The Explosion-proof Design For Intelligent Scanning Test System

The explosion-proof design for scanning test system is aimed to meet the special demand of coal mine, oil and petrochemical industry and it is the key to guarantee safe production and regular order of the industry.Intelligent scanning test system which will be used to supervise manual one can effectively urge worker to arrive on the scene on time according to scanning test plan of fixed person, fixed time and fixed spot. In terms of enterprise management, fractionizing and quantization can be done by fairly rewarding the laborious and punishing the lazy in the light of the scanning test record.The explosion-proof design for intelligent scanning test management system is mainly applied to oil and petrochemical industry which is characteristic of large work filed and much equipment. Volatile gas may exist in the work field and may explode on meeting fire, which will bring about great casualty and property loss. So, strict work rules must be obeyed in these work field and the explosion-proof performance for detect instrument and product equipment must accord with the nation standard. Aiming at these industry specialties, explosion-proof scanning test system will ensure not only safe scanning test but also the safety of workers and environment.Main work in the paper concentrates on the following:1 Safe explosion-proof grade for instrument fitting for coal mine, oil and petrochemical industry is studied and discussed, and design requirement is introduced on the base of the fore.2 How to distinguish dangerous site and explosion-proof grade and choose the type of explosion-proof instrument is detailed.3 National standard and design rule for explosion-proof technology are introduced.4 System main board circuit and mechanical structure are designed according to national standard for volatile gas environment electric device.5 System safety and separate explosion design is explained for the examples of post display communication device and data transmitting card. Explosion-proof files and related enterprise standard are written.Based on the technology development abroad and home, the real need of explosion-proof scanning test system is analyzed and the main design aim, principle and point are put forward. Scanning test system method and function realization are studied and discussed.The characteristics of explosion-proof scanning test system are below:1 Design method is accorded with the national standard of volatile gas environment electric device, different from ordinary scanning test system design method.2 Humanism management of scanning test worker is realized by post display communication device and data transmitting card and the inconvenience of user real operation is solved.
