Why use cell phone signal jammers in gas stations, oil depots and other places?
Currently, mobile phone signals are almost everywhere and all electrical equipment is surrounded by them. When the phone is not in use, this environmental signal can minimize interference with other electrical equipment. This is because when the mobile phone is not in use, the data exchange between the mobile phone and the base station does not occur and a sudden change signal cannot be formed. There is a relatively stable electromagnetic field around electrical equipment, that is, a static electromagnetic field. The interference of this static electromagnetic field with electrical equipment is almost zero. When using a mobile phone, data is exchanged between the mobile phone and the base station to generate random transient signals, thereby generating dynamic electromagnetic fields around electrical equipment. The dynamic electromagnetic field signal may cause a sudden change in the interference signal, which may cause the electrical equipment to malfunction. Installing a GSM jammer is the most effective method of control.
When the phone’s battery is on, the doorbell generates enough power to cause a slight spark, which may cause a fire. The petroleum, chemical, security and other relevant departments have made it clear that the use of cell phones at gas stations is prohibited. It has been a long time since its introduction, but the current implementation is not ideal. The gas station equipment is controlled by a computer. The cell phone signal will affect the normal operation of the device and lead to inaccurate measurement results. Most importantly, when talking on a cell phone, sparks can easily catch fire and explode at a gas station. Therefore, gas stations belonging to fire-resistant zones not only strictly prohibit the use of cellphones at gas stations, but it is also better not to use cellphones within 2-3m around the area. gas station. At the same time, gas stations should put up clear signs, ban phone calls and spread safety knowledge so that people can understand that calls at gas stations undoubtedly go with tigers. The fire across the country caused by the use of cell phones. The dangers of using cell phones at gas stations have attracted a lot of attention. It is recommended to use cell phone signal jammers at gas stations. Sinopec and China National Petroleum Corporation have led the way in using mobile phone signal jammers at gas stations in some areas.
