Nowadays, cell phone jammer are widely used in many industries. At this stage, mobile signals are basically ubiquitous, and all electrical equipment will be surrounded by them. When there is no application of a smart phone, the interference of such surrounded signals to other electrical equipment is almost zero. This is because, when there is no application of a smart phone, there is no data communication between the smart phone and the communication base station. It is also unlikely to form a transition signal. The electrical equipment is surrounded by a relatively stable magnetic field, that is, a static magnetic field. The interference of this static magnetic field on the electrical equipment is almost zero. When using a smart phone, the data information between the smart phone and the communication base station is communicated, and the resulting change signal is formed, so that a dynamic magnetic field is formed around the electrical equipment. This kind of dynamic magnetic field signal will detect Transformed electromagnetic interference can easily cause disorder in electrical equipment.
When the mobile phone is in operation or when the ringing comes, it can form sufficient strength to cause a light spark formed by a flame, which may cause a fire accident. Crude oil, chemical plants, safety and other related departments have clearly stipulated that gas stations prohibit the use of smart phones. It has been a long time since the announcement, but the current situation is not ideal. All gas station facilities are controlled by computers. Mobile signals will interfere with the regular operation of facilities and cause inaccurate measurement and detection. More importantly, the smartphone will cause fires during the dialing process, which is more likely to cause fire accidents. Caused the gas station to explode.
Therefore, the gas stations that belong to the fire-resistant areas not only prohibit the use of smart phones in the stations, but it is also best not to use smart phones within two or three meters of the gas station. In addition, gas stations should set up prominent signs prohibiting smartphone calls, and increase publicity on safety common sense, so that everyone knows that it is undoubtedly very dangerous to use smart phones in gas stations. The risks arising from the use of smart phones in gas stations have long attracted attention from many aspects. It is proposed to use mobile phone signal jammers at gas stations. Many gas stations have already taken the lead in applying cell phone signal blockers to gas stations in some areas.
