Explosion-proof mobile phones are required in mines. At present, the appearance of explosion-proof mobile phones is similar to that of general mobile phones. The difference is that the functions of explosion-proof mobile phones should be simplified. When we choose explosion-proof mobile phones, we should pay attention to the following matters. Choose the right type of explosion protection according to your own safety requirements. The non-sparking type can be used normally in the environment of explosive mixtures, and the intrinsically safe type will not cause an explosion in explosive mixtures even if it fails. The intrinsically safe type is more explosion-proof, and the intrinsically safe type has higher safety performance than the non-sparking type.
The audience of explosion-proof mobile phones is not as extensive as that of ordinary mobile phones, but it plays a more important role than ordinary mobile phones. After getting the explosion-proof mobile phone, be sure to check whether the mobile phone is intact, especially the completion of the battery and interface. If you purchase a non-sparking explosion-proof mobile phone, you must pay more attention to the fact that the mobile phone must not malfunction during operation, otherwise the thermal effect or pad effect produced by the mobile phone is likely to bring life threats. We must pay attention to the explosion-proof grade of explosion-proof mobile phones. According to the explosion-proof standards in Europe, the environment from zone 0 to 2, 0 is the worst, full of explosive gas, and it is very likely to be dangerous. Zone 1 means that there is a hidden danger of explosion during work. Zone 2 is the safest type. Even if there is a hidden danger, it is short-term. These explosive gas mixtures will not stay forever.
Explosion-proof mobile phones can only be used normally in dangerous environments, that is, to view information, answer calls, etc., and never remove the battery directly in the workplace. Although the internal structure of the battery eliminates thermal effects and static electricity, etc., the operation of disassembling and disassembling the battery may still cause static sparks and then cause an explosion. According to the above standards, CONQUEST has produced a number of intrinsically safe explosion-proof mobile phones, and all have passed explosion-proof certification. Conquer the intrinsically safe explosion-proof mobile phone by increasing the protection circuit, increasing the circuit spacing of the circuit board, shielding and packaging electronic components, and using special materials to manufacture the mobile phone casing, to ensure that the electronic components inside the mobile phone are even short-circuited and fail The energy generated at the time is not enough to form an effective ignition source, thereby ensuring the safety of users in flammable and explosive environments.
At the same time, the CONQUEST explosion-proof mobile phone is equipped with a large-capacity battery, which extends the standby time and uses a large screen design for more feelive operation. The overall line of the explosion-proof mobile phone is smooth, the keyboard is resistant to wear and tear, and it can effectively isolate the dust while being waterproof.
In recent years, many coal mines have gradually promoted faster and safer communication technologies, enabling mobile phones to be used in mines, gradually improving mine emergency response capabilities and disposal capabilities, and consolidating the foundation for safe production in mines. CONQUEST controls the energy release rate of energy storage components by adding a current-limiting circuit. At the same time, special materials are used to protect the motherboard to prevent explosive energy from short-circuiting the circuit, thereby achieving explosion-proof safety. The explosion-proof mobile phone developed by CONQUEST uses increased current limiting devices, enhanced circuit safety protection systems, and limits and eliminates the unsafe hidden dangers caused by the fire of mechanical contacts. When the battery has an unexpected fault such as overcurrent, short circuit, overvoltage, the fuse and the transistor are automatically cut off to avoid generating a device that ignites dangerous gases. To ensure the production safety of industrial users and industrial environments. The casing of the CONQUEST explosion-proof mobile phone is also anti-static treated to reduce the surface resistance so that it meets international explosion-proof standards. The safety performance of explosion-proof lithium batteries has passed 3200 non-spark tests and has reached the national explosion-proof safety technical standards. Explosion-proof mobile phone adopts highly protective 6-sided 12-group three-dimensional skeleton. The outer shell is hard plastic with high strength and toughness. It is wrapped with high-density TPU soft shock-absorbing plastic on the outside. Injection molding has powerful rolling resistance. In addition, the mine's intrinsically safe explosion-proof smartphone is loaded with one-click intercom and external camera, supports NFC multi-card aggregation, Beidou + GPS dual-mode navigation, and collects relevant information for emergencies. Mine staff can use the network to achieve Internet access, Video call, monitoring production dispatch command system and ventilation monitoring system are important tools for safe production communication in mines.
