Explosion-proof industrial tablet PCs are often used in petroleum, chemical, coal, and other industries in a very complex environment. In these industries, it is difficult for us to judge the explosive risk factors. In order to ensure the use safety of equipment in these industries, the design of explosion-proof industrial tablet computers must be more professional, so as to fundamentally optimize the performance of explosion-proof industrial tablet computers, Make them more competitive in the market.
The design and manufacturing requirements of explosion-proof industrial tablet computers are as follows.
1. Explosion-proof industrial tablet PCs' power supply design. The storage battery and dry battery belong to an independent power supply that is safe and easy to carry. Both storage battery and dry battery are resistive circuits. The determination of power safety parameters of its power supply can be realized according to the curve of low resistive ignition current. Using the high voltage of the battery, find out the small ignition current, and then divide it by the value of the safety factor to get the allowable safety current of the battery. The direct short circuit of the battery is a very serious discharge state of the battery. Therefore, when designing the power supply, we must consider the intrinsic safety performance of the power supply and take the short-circuit current as of the measurement standard.
2. The circuit design of explosion-proof industrial tablet computer. In the circuit design, the electrical function of the panel PC must be fully considered to ensure the correctness of the electrical principle. Secondly, the insulation parameters, creepage distance, and electrical clearance of explosion-proof industrial tablet PC must comply with the relevant requirements of national standard GB3836.
3. Explosion-proof industrial tablet PC's housing design. The design of the shell must have a strong capability of anti-collision, impact resistance, anti-static, and excellent thermal conductivity performance.
The explosion-proof industrial tablet PC is an important factor to determine whether enterprises in petroleum, chemical, coal, and other industries can produce smoothly. Therefore, the design and manufacture of explosion-proof industrial tablet PC must be strengthened and the quality must be guaranteed.
