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 everywhere. All mobile phones and electronic devices we commonly use are covered. In the past, when there were no mobile phones, the all-round coverage of data signals had little impact on other electronic devices. This is because, when there were no mobile phones, it was impossible for the mobile phone to communicate and connect with the mobile base station, and it was unlikely to cause a sudden change in data signals. There is a relatively stable electromagnetic field near the electrical equipment, which is actually a data format electromagnetic field. The impact of this data format electromagnetic field on the electrical equipment is almost zero.
However, when we popularize mobile phones in front of us, there will be no data and information communication and connection between the mobile phone and the mobile base station, which will cause a sudden change in data signals at any time, so that other electrical equipment nearby will have a dynamic electromagnetic field. This dynamic electromagnetic field signal will induce a sudden change in interference signal, which is easy to cause the information function of the electrical equipment to malfunction. When the mobile phone is running and ringing, it can cause sufficient mechanical energy to cause a slight discharge phenomenon caused by corona discharge, which is very likely to cause a safety accident. Relevant departments such as gas stations, chemical companies, and safety factors have clearly stipulated that it is strictly forbidden to use mobile phones to make calls at gas stations. The current implementation of portable mobile phone signal blockers is not ideal. Why are portable mobile phone signal blockers so popular in chemical plants and gas stations?
The mechanical equipment at gas stations is controlled by computers. Data signals 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 easy to cause safety accidents and gas station explosions. Therefore, gas stations, which are a must for fire safety, not only prohibit mobile phones in the internal structure of the search engine, but also do 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 mobile phone calls, and widely publicize the necessity of safety knowledge to let everyone know the risks of using mobile phones at gas stations. But even if it is explicitly prohibited, some people still think it is sensational and violates the rules. Faced with this situation, portable cell phone signal blockers have the last line of defense to prevent the use of mobile phones at gas stations.
