The survey found that gas stations must use signal jammers. Today’s mobile phone data signals are almost everywhere, and all electrical equipment is surrounded by them. When the mobile phone is not in use, the information ratio of other electrical equipment is not good, because there is no data communication between the mobile phone and the communication base station, and it is impossible to form a fusion signal.
Electrical equipment is a relatively stable electromagnetic field, that is, a static electromagnetic field. The interference of static data electromagnetic fields on electrical equipment is almost zero. When using a mobile phone, there is data exchange between the mobile phone and the communication base station, and any sudden change in the signal will cause an electromagnetic field to form around the electrical equipment. This dynamic electromagnetic field signal and magnetic induction suddenly invade the signal, which can easily lead to an imbalance in the function of the electrical equipment. This is what a cell phone jammer means at the gas station.
Why gas stations must use cell phone signal jammers
When the cell phone battery is running and the ring is heard, it can generate enough energy to cause a tiny flame to form a spark discharge, which may lead to a fire accident. Safety-related departments have clearly stipulated that gas stations prohibit the use of cell phones and have issued regulations for a long time. It has been implemented for some time, but the current implementation situation is not ideal. The facilities of the gas station are controlled by computers. The mobile phone signal will affect the normal operation of the facility and cause measurement failure. More specifically, the mobile phone will emit flames during the dialing process, which can easily cause fire accidents and lead to Gas station construction blasting.
Adding cell phone jammers to gas stations can prevent some unfortunate incidents. Therefore, gas stations classified as fire safety areas not only prohibit the use of mobile phones within the website, but also prohibit the use of mobile phones within two or three meters of the gas station. At the same time, gas stations should set up obvious representatives to discourage cell phone calls, widely spread safety knowledge, and let people know that using cell phones at gas stations is undoubtedly a tiger in the same industry.
Why do gas stations use cell phone signal jammers?
There have been several fire accidents caused by the use of mobile phones in China. A gas station exploded because a driver was using his mobile phone to refuel, causing many casualties. There have also been several fire accidents and emergencies caused by mobile phone use at gas stations in Shenzhen, Chongqing and other places. The risks posed by using mobile phones at gas stations have attracted attention from many quarters.
