Why use cell phone signal jammers in gas stations, oil depots and other places?
The current mobile phone signal is almost everywhere, and all electrical equipment is 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 exchange 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, that 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.
When the battery of the mobile phone is started, when the bell 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 is not ideal. The equipment at the gas station 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 from the mobile phone, which can easily cause a fire and cause an explosion at the gas station. Therefore, the gas station that is a fire-resistant area is not only strictly forbidden to use mobile phones in the station, but it is 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. The dangers of using mobile phones at gas stations have attracted many attentions. It is recommended that gas stations use mobile phone signal jammers. Sinopec and China National Petroleum Corporation have taken the lead in using mobile phone signal jammers at gas stations in some areas.
