The use of mobile phone signal jammer in gas station

　　When the mobile phone battery starts, when the ringing rings, it can generate enough energy to cause a slight spark, which may cause a fire. Petroleum, chemical, security, and other relevant departments have clearly stipulated that gas stations prohibit the use of mobile phones. It has been a long time since the introduction, but the current implementation situation is not ideal.

　　Gas station equipment is controlled by a computer. The signal from the mobile phone will affect the normal operation of the equipment and cause inaccurate measurement. More importantly, sparks will appear during the call on the mobile phone, which can easily cause fire and cause the gas station to explode. The current mobile phone signal is almost everywhere, and all electrical appliances are surrounded by it. When the mobile phone is not in use, this kind of surrounded signal has minimal interference to other electrical equipment. This is because when the mobile phone is not in use, there is no data communication between the mobile phone and the base station, and it is impossible to form a sudden change signal. The electrical equipment is surrounded by a relatively stable electromagnetic field, which is a static electromagnetic field. The interference of this static electromagnetic field to the electrical equipment is almost zero.

　　When using a mobile phone, there is a data exchange between the mobile phone and the base station, which generates a random mutation signal, which causes a dynamic electromagnetic field to form around the electrical equipment. This dynamic electromagnetic field signal will induce a mutation interference signal, which is easy to Cause dysfunction of electrical equipment. Therefore, gas stations that are a fire-resistant area are not only strictly prohibited from using mobile phones in the station, but it is also best not to use mobile phones within two or three meters around the gas station.

　　At the same time, gas stations should set up obvious signs prohibiting cell phone calls, and widely publicize safety knowledge, so that people understand that calling cell phones in gas stations is undoubtedly walking with the tiger. There have been many fires caused by the use of mobile phones across the country. A gas station in Henan caused an explosion when the driver used his mobile phone while refueling, causing a huge accident involving many deaths and injuries. There are also many fire dangers caused by mobile phones in gas stations in Shenzhen and Chongqing.

　　The dangers of using mobile phones at gas stations have attracted many attentions. Relevant departments in Beijing, Hubei, Inner Mongolia, Guangdong, Henan, Shandong, Jiangxi, Sichuan, Chongqing and other places have recommended the use of mobile phone signal jammers at gas stations under their jurisdiction. Sinopec and China National Petroleum Corporation have taken the lead in using mobile phone signal jammers at gas stations in some areas. In short, do you understand now? This is why cell phone signal jammers are used in gas stations, oil depots and other places.

　　MDPB-5E (6 channels) upgraded version of mobile phone signal jammer is a mobile phone signal jammer specially developed and produced by adopting international advanced shielding technology to meet market demand. The equipment has undergone a brand-new upgrade, changing from 5 channels to 6 channels increases the shielding effect of the device itself on the signal. At the same time, the newly added 4G frequency band solves the disadvantages that other products cannot shield the 4G frequency band, and the shielding effect is superior to other similar products. The shielding effect is stronger, the performance is more stable, and it is easier to be recognized and accepted by customers. The MDPB-5E (6 channels) upgraded version of the mobile phone signal jammer can automatically form a shielding magnetic field within the specified range when entering the working state, forcibly disabling mobile phone signals, the MDPB-5E (6 channels) upgraded version is only for mobile phone communication signals Shielding, without interfering with other electronic devices, has also become its rare advantage. The advent of the MDPB-5E (6 channel) upgraded version of the mobile phone signal jammer may completely solve the harm caused by the information leakage of communication facilities to users, allowing people to enjoy the speed and convenience brought by high-tech to mankind while ensuring The security of its information.
