Mobile phones bring safety hazards to gas stations

The number of small cars in Shenzhen is growing rapidly at a rate of 200 vehicles per day. How much do new drivers know about the safety regulations of gas stations? Yesterday, the reporter randomly interviewed several gas stations in the city and found that although the safety warning signs in the gas stations were very eye-catching, many drivers turned a deaf ear to the safety regulations such as banning mobile phones and turning off vehicles when refueling.

Most drivers have used their mobile phones at gas stations. How many people have complied with the safety rule of “turn off the vehicle when refueling”? The reporter interviewed several gas stations in the city and learned that 80% of novices often need to remind the fueler to stop the fuel when refueling. Old drivers generally do not need to remind the fuel to stop, but some old drivers do not want to stop the fuel because of trouble.

At the Sinopec gas station on Hongli Road, Ms. Huang from Meilin Village told reporters about her dangerous experience. Once when she refueled, she got out of the car without stalling, and the fueler reminded her to refuel after stalling the car. When she was refueling, her cell phone rang, and the fueler asked her to stand farther away to answer the phone. At that time, she felt a little unhappy in her heart, thinking that the fueler was very unkind. When she was standing far away on the phone, she suddenly heard a strange noise from the spray gun being refueling, and saw a sudden electric spark flashing from the front of the car. Although the spray gun automatically stopped refueling later, Ms. Huang was shocked. She told reporters that if it weren’t for the reminder of the fueler, it might have caused a catastrophe.

At a gas station near Liantang in Luohu District, 15 vehicles came to refuel within 20 minutes. Among them, 9 drivers were talking and laughing on their mobile phones while refueling. When the fueler was refueling a car, the driver’s mobile phone rang, and the driver picked up to answer the call. Although the fueler saw this scene, he did not remind the driver. On a pillar next to him, there was a post “No mobile phone use”. The striking goal.

During the reporter’s interview, two-thirds of drivers said they had used their mobile phones at gas stations, and many drivers even said they didn’t know this rule at all. A Mr. Zhu said: “I have never heard that calling on a mobile phone in a gas station will cause an explosion.” Many drivers think this is a big or small matter, and there is no need to make a fuss. Illegal operations can easily lead to accidents. It is common knowledge that fireworks are strictly prohibited at gas stations, but it is not clear to so many people that dialing or receiving mobile phones at oil depots or gas stations or refueling without turning off the flame may cause an oil and gas explosion. As more and more people use their mobile phones at gas stations and do not turn off the gas to refuel, relevant people warn that such illegal operations may become the fuse of an oil and gas explosion, and its danger is tantamount to playing with fire.

A person from the petrochemical company said that the density of oil and gas around the vehicle will increase sharply when refueling. At this time, the electronic friction generated by the mobile phone in the transmitting or receiving state may ignite the gasoline and cause an explosion. In fact, the manual of general mobile phone products will indicate: Do not use the mobile phone at the gas station! At the same time, the reporter learned that only last year, gas stations in Yueyang, Zhengzhou, Changsha, Lanzhou and other places had exploded due to the use of mobile phones, causing serious incidents of casualties.

How far is the most suitable shielding range of a mobile phone signal jammer?

The shielding distance of the device has a great relationship with the power of the device and the use environment, and several aspects that are helpful to the shielding effect: one is the output power of the device, the other is the working method of the shield, and the third is the use environment (indoor or outdoor). The fourth is to shield the interference intensity of the surrounding environment.

Nowadays, mobile phones are all digital signals, and the anti-interference ability of digital signals is very strong. Generally, the effect of using analog signal technology to interfere with digital signals is poor. Therefore, digital signals must be used to interfere with digital signals. The interference effect is quite different. The signal jammer using digital jamming signal technology has lower power and higher efficiency than the jammer using analog signal jamming technology.

The synthesis, attenuation, and reflection analysis of indoor mobile phone signals and interference signals is very complicated. Before shielding, the strength and quality of local cell phone signals have a great impact on shielding. Different mobile phones have different effects. Generally, mobile phones with strong ability to receive weak signals may not have good anti-interference effects.

The direction of the base station and the direction of the shielded area of ​​the mobile phone also affect the shielding effect. Generally, the spatial signal strength is about -60 to -70dbm, and the base station can reach about -40dbm within a few hundred meters, and the mobile phone reception strength range is generally between -35 to -95dbm. The higher the signal power of the space mobile phone, the shorter the shielding distance.

The above conclusions are based on the law of radio signal transmission in free space. In reality, there are many obstacles on the ground that affect the transmission of radio waves. The above can only be qualitatively used as a reference, especially indoors. The above law is very different from the actual situation. Therefore, this problem is difficult to calculate accurately at the time, and can only be determined based on the actual situation on site. Precise construction projects must carry out preliminary research and signal testing, and then design specific solutions. In the later period, timely follow-up tests are required, and certain corresponding supplements can be foolproof, that is, to achieve the effect of strict shielding.

Drones are causing trouble again

From 6 am to 6:30 am local time on May 14, Saudi Aramco’s pumping stations 8 and 9 were attacked by drones, and the company was forced to temporarily close the east-west pipelines. The Yanbu Port that was attacked this time was even more than 700 kilometers away from the Houthi armed forces’ control area, and the ASEF-1 small drones currently in the hands of the Houthi are simply not enough to support such a distance. Voyage. The only explanation is that the attack was caused by a Houthi-armed drone attack squad that penetrated the border between Yemen and Saudi Arabia and carried out a long-distance attack.

Affected by this incident, international oil prices rose sharply during the intraday session, and the intraday increase once exceeded 1.5%.

In March of this year, the Houthi UAV has publicly reached an important strategic goal in southern Saudi Arabia: Suqa Phase 2 of independent desalination and power plants. Compared with the last reconnaissance operation on Suqa Plant 2, the attack on Yanbu is even more shocking, which is too far away from Yemen. Yanbu is located in the central area of ​​Saudi Arabia’s Red Sea coast. The closest distance to Yemen is more than 800 kilometers. The range of small drones in the hands of Husseis is not that far. For such a long-distance flight, at least a medium-sized drone of the level of Rainbow 3 is required. The flying distance has exceeded the direct communication distance between air and ground. Satellite relay communication equipment is required to ensure the communication between the drone and the ground station. Because of the Houthi armed forces’ equipment level and organizational capabilities, the take-off point for this attack cannot be in Yemen. Either take off from the sea, or secretly infiltrate and take off near Yanbu. Obviously the former is the least difficult to implement.

The seven UAVs used in the attack were QASEF-1 suicide UAVs in the hands of Hu Sai. The pictures and information of the aircraft that Hu Sai has shown to the outside world are based on Iran’s Ababil-2 UAV. The maximum flight distance can reach 150 kilometers, the length is 2.5 meters, and the wingspan is 3 meters. Small fishing boats can carry it. . It is very likely that the fishing boat controlled by Husai sailed concealedly to the sea off Yanbu Port. The 150-kilometer voyage can ensure that the ship is on the high seas. The total weight of the warhead carried by the 7 QASEF-1s is 210 kg, which is enough. Two carefully selected pumping stations caused serious damage.

This shows the touching degree of the combat power of the Saudi “Royal Army”. First of all, the borders of their homes were infiltrated by the armed men of the other side without even knowing it, and they were allowed to run hundreds of kilometers in their own territory. What’s more, Iran’s aid to the Houthi armed forces has been significantly reduced after the sanctions. This can be said to be a wave of high-profile UAV counterattacks by the Houthi armed forces against Saudi Arabia under desperate conditions. Saudi Arabia, whose annual military expenditure is as high as 67.6 billion U.S. dollars, has nothing to do with it!

It’s time to consider using drone jammer to counter drone.

Mobile phone signal jammer installation and technical advantages of conference room signal jammer

Many companies will install signal jammer in conference rooms. The main reason is that they don’t want to let the phone call in to disturb the progress of the meeting. What are the technical advantages of signal jammers in conference rooms? What are the installation methods of signal jammers? Below jammer-mart Let me introduce you.

newest hidden mini cell phone jammer

Advantages of existing technology of mobile phone signal jammer:

(1) The new cell phone jammer can already achieve the IMSI number obtained in the 4G mode, which does not disturb the people, does not interfere, and is green;

(2) Which floor in that area has a mobile phone violation alarm, that is, the shielding device in the area is activated, not all devices in the entire unit’s supervision area are activated together, not for a long period of time, so the shielding effect is very small, the time limit is very short, green Environmental protection;

(3) Leading technology, mature and reliable, in line with the technical prevention requirements of national signal control;

(4) It can effectively block the 2G+3G+4G mobile phone standards that all mobile\linkage operators have opened and run today.

Installation method of mobile phone signal jammer

1. When using an external mobile phone signal jammer with an antenna, lock the letter on the antenna corresponding to the letter on the host, and then turn on the power.

2. The mobile phone signal jammer with built-in antenna is easier to use. Just plug in the power and turn on the switch.

Why drones become a nightmare at British airports

London’s Gatwick Airport (Gatwick Airport) has been closed for more than one day under the influence of drones, affecting more than 700 flights and affecting approximately 100,000 passengers. The local police have yet to find anyone operating the drone, but they suspect that it may be the work of environmentalists.

A Gatwick Airport spokesperson pointed out that the British police and military have provided additional precautions for the airport to allow the airport to reopen and allow aircraft to take off.

Many drones are now cheap, and you can buy them for as little as tens of dollars. But the BBC science and technology reporter Jane Wakefield (Jane Wakefield) reported that these small aircraft can have a huge impact on civil aviation traffic.

What is the impact of drones on aviation safety?

A UAV collided with a civil airliner at an airport in Canada in October 2017. The wing was slightly damaged, but it still landed safely afterwards.

We are not yet fully aware of the consequences of a collision between a UAV and a civil airliner. Many organizations have done relevant research to simulate the consequences of collisions between drones and passenger planes in different situations, but the conclusions of each test seem to be different.

The University of Dayton in the United States simulated a collision between a one-kilogram drone and a civil aircraft flying at 383 kilometers per hour. The results showed that the passenger aircraft was seriously damaged.

If there is a drone jammer gun, will the situation be better?

The UAV counter-gun is a kind of electromagnetic interference equipment with a gun type, which is not only a gun type but also a splint type. The principle of this weapon is to emit electromagnetic interference waves between 2.4GHz and 5.8GHz, interrupting the connection between remote control equipment and drones. Because most drone remote controls are also in this frequency range. The operating distance is within 1000 meters, which can force the long-distance low-altitude drone to fall, return to the operator or descend smoothly in a short time, thereby realizing effective control of flying drones in the “control area”.

Talking about the advantages of UAV jammers

Today, more and more people complain that their personal lives are often exposed to unauthorized drones. UAVs are very famous today, they are usually used to capture important events or certain objects from the air. Since these technologies do not stand in the same place, new and more advanced models of drones and squares are being created every day that can turn your personal life into the object of particularly curious espionage.

Intruders are one kilometer or more away from objects protected by traditional security systems. They can conduct industrial espionage from the air, monitor private life, throw prohibited items around guards or export valuables, and drugs bypass control points and inspections. Considering the growing threat of terrorism around the world, the use of drones carrying explosive devices can be expected to attack crowded locations and sensitive infrastructure elements. Equally dangerous is the drone, whose operators simply lose control and stay away. Such drones are in the airport area even at very high altitudes, and can enter the engine of the flying or landing aircraft and turn off the power cord.

Thieves can obtain detailed information about the location of guards and installed CCTV cameras, the location of storage facilities, and the number of any secret equipment. As you can see, with the help of drones, detailed information can be obtained. Therefore, if you want to protect yourself from unauthorized entry into your personal life or business, then you should know what drone jamming technology is. The jammers of quadcopters and drones are high-power devices that can block the audio and video transmission of information. These devices are beneficial because they can store confidential materials.

When choosing a drone jammer, please pay attention to the spectrum of the blocking frequency. The drone jammer is a powerful device that can effectively prevent the operation of the following frequencies: video transmission frequency (2.4G WIFI 2400-2500MHz 20W); remote control frequency (2.4G WIFI 2400-2500MHz 20W); ˚F video Transmission and remote radio control (5.8G 5.5-5.9MHz 2W) rate; ˚F remote radio control nuclear rate (868-912 MHz, 860-920MHz 25W, 20W 433-434MHz); GPS frequency L1 1575 MHz 40W.

The anti-drone jammer is equipped with multiple pin antennas. The length of the antenna can be different. The blocking radius of the suppressor can also vary according to the signal strength, location, and remoteness of the basic control. The more powerful the function you choose, the larger the blocking radius. It is important to note that the jammer has a low-noise built-in fan. With such a reliable cooling system, you can stay calm and overheating will not pose a threat to you.

Most drone radio jammers have unlimited working hours, so you can use it for a long time. Signal jammer is specifically used for advantageous purposes to ensure control of the territory, prevent industrial espionage, counter-terrorism purposes, attempts to move narcotic substances, certain types of weapons, personal family information or commercial espionage, etc. 2.4 GHz jammer for drones-ideal for any citizen who cares about privacy. If you have any questions about drone blockers, you can call our manager or send a message. We are happy to answer all your questions. In addition, we will help you choose a suppressor that meets all your requirements.

A hundred shots and a hundred hits within 2000 meters, the drones dare to fly randomly?

The UAV counter-gun is a kind of electromagnetic interference equipment with a gun type, which is not only a gun type but also a splint type.

The Wuhan police demonstrated that they are equipped with the latest domestically-made “electromagnetic rifles.” In the opening match of the China League One held last week, a drone of unknown origin broke into the event site, seriously disrupting the progress of the game. Afterwards, the Wuhan police took out their new equipment-a silver-gray drone counter-gun about 1 meter long, and “shot down” the opponent with a single shot. On the day of the match, the Wuhan police used the gun six times to expel the approaching drone.

portable drone blocker gun-type

The drone was not broken into pieces, but landed slowly on the ground. According to the International Business Times, the principle of this weapon is to emit electromagnetic interference waves between 2.4GHz and 5.8GHz, interrupting the connection between remote control equipment and drones. Because most drone remote controls are also in this frequency range.

This drone jammer uses a combination of an integrated information source and a broadband power amplifier, and the source integrates 8 frequency bands. The full frequency band coverage of radio from 300MHz to 6GHz is closer to the current mainstream UAV radio remote control and image transmission signal modulation method. The intensity of electromagnetic waves it emits is 8 times that of ordinary jammers. It can accurately distinguish various drones at a distance of 3 to 5 kilometers, and effectively intercept within a range of 500 meters to 2000 meters.

The “artificial weapon of military force” between Turkey and Russia

The “Krasukha” land-based electronic jamming system is the most advanced signal jammer equipped by the Russian armed forces. The system can effectively interfere with land-based radars, aerial radars, early warning aircraft, and even near-Earth satellites within 300 kilometers. The system is said to permanently damage the target radio equipment.

Russia has already deployed a “Klasuha” land-based electronic jamming system in Syria. Compared with Turkey’s “Koral” portable radar jamming system, “Krasuha” has a wider interference range. “Krasuha” can blind the Turkish Air Force’s “Peace Eagle” early warning aircraft, making it impossible for the Turkish side to map the airspace of Syria and the Eastern Mediterranean, and greatly reducing its interception capabilities.

The Russian “Glory”-class guided missile cruiser has advanced maritime combat platforms and air defense platforms, equipped with 16 “Bazart” anti-ship missile launch systems, 64 S-300PMU long-range air defense missile systems and two “Wasps” short-range Surface-to-air missiles. The “Glorious”-class guided missile cruiser has advanced functions such as three-dimensional search and radar tracking, and is called a “floating fortress.” After the Russian fighter plane was shot down on November 24, a “Glorious”-class guided-missile cruiser has been deployed to Latakia Port in Syria.

However, the “Glorious”-class guided-missile cruiser is not without flaws. This class of cruisers lack effective anti-submarine firepower, especially when capturing stealth underwater targets such as Turkish “Gul” class submarines. In addition, Russia has only one “Glorious”-class guided-missile cruiser that can be used in the Syrian region, and several other ships are deployed in the Baltic Sea and the Pacific Ocean.

Russian special forces have a long-standing reputation and have performed a large number of special missions since the Soviet era. They can perform various missions such as long-range raids, assassinations, sabotage, and lurking. It has multiple teams and branches, and its most recent appearance is said to be a “little green man” who suddenly appeared in the Crimea region in February 2014. Many think tanks believe that the Russian special forces are the sword that Ankara is most worried about. Ankara’s envisioned plot includes Russian special forces disguising as Syrian refugees and mixing into southern Turkey and performing special tasks.

6 ways to prevent decoder theft

When the car owner locks the car, it intercepts the decoded signal sent from the car’s key to the car’s central control lock device, analyzes the frequency and data in it, and copies this signal to control the car door lock and easily steal the owner’s car or car property.

The car GPS jammer has a low technical content. The principle is to send out a frequency similar to the original car key signal, and the signal is strong, covering the original car key signal, making the vehicle unable to lock the door, and taking the opportunity to steal the property or the vehicle after the owner goes away .

car gps anti track blocker

“This kind of device is a decoder, rather than a codecutter, because it mainly relies on intercepting the signal to copy the signal.” Master Su said, the public need not be too panic, because only when the owner of the car is opening or locking the car, it is illegal. Only the disciples can take advantage of it. However, in order to avoid property damage, Master Su reminded the majority of car owners to be more careful when parking.

Learn the following 6 tips to reduce the chance of theft of vehicles and their belongings:

1. When you lock the car, pay attention to whether there are suspicious persons within 10 meters.
2. When locking the car, the owner should not be too far away from the car to reduce the range of sensor sensing by the decoder.
3. When using the car anti-theft alarm, install a mechanical anti-theft device and install several concealed locks, such as steering wheel locks and gear locks, so you are not afraid of any decoder.
4. Look for a more side-by-side anti-theft method, do not install the anti-theft device in a fixed position, which increases the time of the thief’s crime, and the thief will lose patience, thereby reducing the chance of successful theft.
5. Load the GPS global positioning system on the car. Even if the car is stolen, the police can quickly locate the stolen vehicle and retrieve the stolen vehicle as soon as possible.
6. It is still necessary to emphasize that you should not put valuables such as leather bags, mobile phones, cash, etc. in the car to avoid losses caused by criminals.
