At this stage, data signals are basically ubiquitous, and all electrical equipment will be surrounded by them. When there is no mobile phone application, the surrounding data signals have little impact on other electrical equipment. This is because when the mobile phone is not on the mobile phone, there is no data communication between the mobile phone and the communication base station. Suddenly changing data signals are unlikely to be generated. There is a relatively stable magnetic field around the electrical equipment, which is a magnetic field of static data. The impact of the magnetic field of this type of static data on the electrical equipment is almost zero.
When you use the mobile phone, you have the data information communication between the mobile phone and the communication base station, which causes any sudden changes in the data signal, causing a dynamic magnetic field around the electrical equipment. This kind of dynamic magnetic field data signal, Sudden changes of electromagnetic interference will be magnetically induced, which can easily lead to neurological disorders of electrical equipment. When the mobile phone is started and ringing, it can cause sufficient kinetic energy to cause a spark discharge caused by a slight flame, which is likely to cause a fire accident. Crude oil, chemical plants, safety and other related departments have clearly stipulated that gas filling stations are strictly prohibited from using mobile phones. The implementation of cell phone jammer equipment can be implemented at this stage. The situation is not ideal.
The machinery and equipment of the gas station are all controlled by a computer. The data signal will endanger all the normal operation of the machinery and equipment, and will cause the measurement verification prohibition. More importantly, the flame will appear during the whole process of dialing on the mobile phone, which is very easy. It caused a fire accident and caused the gas station to explode. Therefore, gas filling stations that belong to a place of fire safety are not only prohibited from using mobile phones inside the website, but it is better not to use mobile phones within two or three meters of the gas station. In addition, the gas station should set a prominent sign that it is strictly forbidden to dial through the mobile phone, and increase publicity on the importance of common sense of safety, so that everyone understands that calling on the mobile phone in the gas station is undoubtedly the same industry.
There have been several fire accidents caused by mobile apps in various parts of the country. A gas station in Henan Province caused an explosion due to the driver’s application of the mobile phone when supplying fuel, resulting in a major safety accident that caused many casualties. There were also several fire accidents and emergencies caused by mobile phone calls at gas filling stations in Shenzhen, Chongqing and other places. The risks arising from the application of mobile phones in gas stations have already caused great attention in all aspects. Relevant departments in Beijing, Hubei Province, Inner Mongolia Autonomous Region, Guangdong Province, Henan Province, Shandong Province, Jiangxi Province, Sichuan, Chongqing City and other places have proposed the application of wireless signal shielding equipment to gas filling stations under their jurisdiction. The headquarters of Sinopec and China National Petroleum Corporation have already applied wireless signal shielding equipment to gas filling stations in some areas.
