When the battery of the mobile phone is started, when the bell rings, it can generate enough energy to cause a slight spark to generate electric sparks, 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. Even if Cell Phone Signal Jammer Arduino is installed in some public places, the effect is not very satisfactory. The equipment at the gas station is controlled by a computer. The signal of the mobile phone will affect the normal operation of the equipment and cause the measurement inaccuracy. More importantly, the mobile phone is dialing. Sparks will appear during the process, which can easily cause a fire and cause an explosion at the gas station. 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 will cause minimal interference to other electrical equipment. This is because, cell phone jammer 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, which is a static electromagnetic field. This static electromagnetic field affects the electrical equipment. The interference is almost zero.
When using a mobile phone, there is a data exchange between the mobile phone and the base station, which also 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 The dysfunction of electrical equipment. 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 an obvious sign Cell Phone Signal Jammer Arduino prohibiting cell phone calls, and widely publicize safety knowledge, so that people understand that calling on 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, Chongqing and other places.
