At present, the wireless communication network used in most China refinery plants has been covered, mainly used to complete the daily voice dispatch function in the plant. However, with the development of the refinery and chemical plant business, the refinery and chemical plant is becoming more intelligent, and it is necessary to freely control the production activities such as production inspection, safety hazards, logistics and warehousing, and personnel positioning through various communication technologies. For some enterprises, the explosion-proof walkie-talkie in the traditional sense can not fully meet the needs of the company's business expansion. For this reason, the intelligent explosion-proof intercom mobile phone enters the market , which is favored by refining and other industries Conquest (CONQUEST) S8 intelligent explosion-proof intercom mobile phone, not only an explosion-proof smart phone, but also can be used as an intercom mobile phone, support PTT hardware intercom, can achieve one-to-one, one-to-many function, without time, space , geographical restrictions, at the same time can cross-system platform, cross-operator and other multiple advantages. The flexible use of the hardware intercom function can make up for the shortcomings when the signal of the plant is disturbed and the voice of the software is inconvenient. ! Conquest (CONQUEST) S8 has a more stable and advanced Android 7.1 system than the regular walkie-talkie, 4G full Netcom, CPU  8 core 2.0GHZ, the front and rear camera pixels are 8 million and 16 million respectively, the memory is 128GB 6GB, can load the corporate office APP Collect and store video and picture information. In addition, it also supports GPS positioning, with distance, light sensor, support NFC, WIFI, barcode scanning and other functions, which is convenient for factory staff positioning, data reading and writing and transmission. Generally, the equipment area and tank area of various steel frame structures are distributed in the refinery plant area. In the daily inspection work of the staff, the inspection personnel only need to bring this intelligent explosion-proof intercom mobile phone, and quickly explain through the verbal description. On-site issues, coupled with live video or photos back to the work platform, can allow the relevant departments of the Enterprise Security Division to understand the situation, quickly locate the problem, and come up with a solution. In the daily production scheduling, the staff can also join the conference in real time through the intelligent explosion-proof intercom mobile phone, and dispatch the production site situation to the conference for viewing. The meeting staff can see problems at any time, find the problem and propose a solution. Compared with general explosion-proof walkie-talkies, smart explosion-proof walkie-talkies have more diverse and convenient functions, and still retain the compact and portable characteristics of traditional explosion-proof walkie-talkies. In the long run, the application of smart explosion-proof intercom phone can reduce the maintenance cost of enterprises, solve the problem that traditional explosion-proof intercom used in refineries can only "listen" but not "see". Through the return of data, video and pictures, the transmission efficiency of information can be improved, and the production data and equipment status information can be realized. Circulation, management and control.
