Car gas station, natural gas station, petrochemical plants and other sites must use wireless signal blocker. At this stage, data signals are basically ubiquitous, and all electrical equipment will be surrounded by them. When the mobile phone is not used, the impact of such surrounded data signals on other electrical equipment is very little. This is because when the mobile phone is not used, there is no data information between the mobile phone and the communication base station. It is unlikely to generate a sudden change of data signal. The electrical equipment is surrounded by a relatively stable magnetic field, that is, a magnetic field of static data. The magnetic field of such static data has almost zero influence on the electrical equipment.
When the mobile phone is used, it has the data information exchange between the mobile phone and the communication base station, which causes any sudden change of data signal, so that a dynamic magnetic field is generated around the electrical equipment. This kind of dynamic magnetic field data signal, Electromagnetic interference that magnetically induces sudden changes can easily lead to neurological disorders in electrical equipment. When the mobile phone starts and the ringing comes, it can cause sufficient kinetic energy to cause spark discharge caused by a slight flame, which is likely to cause a fire accident. Relevant departments such as crude oil, chemical plants, and safety have clearly stipulated that gas stations are strictly prohibited from using mobile phones. The implementation of wireless wifi signal jammer is not ideal at this stage.
The machinery and equipment of the gas station are all controlled by computers. The data signal will endanger the normal operation of the machinery and equipment, and will cause the prohibition of the measurement verification. More importantly, the mobile phone will appear on the phone during the whole process of dialing, which is very easy. Caused a fire accident and caused the gas station to explode. Therefore, the gas station belonging to the fire safety center is not only prohibited from using mobile phones inside the website, but also does not need to be used on mobile phones within two or three meters around the gas station. In addition, the gas station should set a prominent sign on the mobile phone that is strictly prohibited, and increase the importance of publicity to safety common sense, so that everyone understand the seriousness of calling at the gas station
