Why are portable mobile phone signal jammers so popular in chemical plants and gas stations?

Today's information development is very mature. It can be said that there are unlimited signals wherever you go, and all mobile phones and our commonly used electronic devices have been covered. In the past, when there was no mobile phone, the omni-directional coverage of data signals had very little impact on other electronic devices. This is because before there was no mobile phone, it was impossible to have data and information exchange and contact between the mobile phone and the mobile base station. Perhaps it was not possible. As a result of the sudden change of the data signal, there is a relatively stable electromagnetic field near the electrical equipment. In fact, it is an electromagnetic field in a data format. The electromagnetic field in this data format has almost zero impact on the electrical equipment.

However, when mobile phones are popularized in front of us, there will be no data and information exchange and connection relationship between mobile phones and mobile base stations, which will also lead to sudden changes in data signals at any time, causing a dynamic electromagnetic field to appear in other electrical equipment attached to it. , This kind of dynamic electromagnetic field data signal will induce a sudden change of interference signal, which is very easy to cause information dysfunction of electrical equipment. When the mobile phone is running and ringing, it can cause corona discharge caused by a slight discharge phenomenon caused by abundant mechanical energy, which is very likely to cause a safety accident. Relevant departments such as refueling, chemical industry, and safety have clearly stipulated that gas stations are strictly prohibited from using mobile phones to make calls, and the current implementation of portable cell phone signal jammer equipment is not ideal. Why are portable mobile phone signal jammers so popular in chemical plants and gas stations?

The machinery at the gas station is controlled by computers. The data signal will seriously affect the normal operation of all mechanical equipment, and measurement and detection are strictly prohibited. More importantly, there will be flames when the mobile phone is dialed, which is likely to cause safety accidents and gas station explosions. Therefore, the gas station, which is a must for fire safety, not only prohibits mobile phones in the internal structure of the search engine, but also does not need to use mobile phones within two or three meters near the gas station. In addition, gas stations should set up obvious signs to prohibit calling mobile phones, and widely publicize the necessity of safety knowledge so that everyone can understand the risks of using mobile phones at gas stations. But even if it is expressly prohibited, some people still think it is sensational and violates the rules. Faced with this situation, the portable mobile phone signal jammer has the last line of defense to avoid the use of mobile phones at gas stations.

There are currently several accidents nationwide due to the use of mobile phones. A gas station in Sichuan Province caused an explosion accident due to the driver's mobile phone while stepping on the gas pedal, causing many fatalities and injuries. There are several safety accidents and emergencies caused by dialing mobile phones at gas stations in Shenzhen, Chongqing and other regions. The risks caused by using mobile phones at gas stations have already attracted great attention from all parties. Relevant departments in Beijing, Hubei Province, Inner Mongolia Autonomous Region, Guangdong Province, Henan Province, Shandong Province, Jiangxi Province, Sichuan Province, Chongqing City and other regions have suggested that gas stations under their jurisdiction use portable mobile phone signal jammers. The headquarters of Sinopec and China National Petroleum Corporation have already used portable mobile phone signal jammers at gas stations in some areas.
