What is the price of Liaoning explosion-proof smartphone
For a long time, domestic and foreign wireless communication technology has been stuck in the narrow band low-speed range, the prevalence of equipment complex, single function, can not be reused channels, repeated wiring problems. Chongqing Branch in a large number of preliminary research, data collection, analysis and summary of the basis of the current domestic and foreign mature Wi-Fi technology, combined with the wideapplication of RFID technology, through technical improvement, essential safety design, developed a special environment to adapt to the mining wireless communication system.
Wireless communication system as a new generation of mine wireless transmission system, using Wi-Fi and RFID technology, in the explosion-proof realization of a system to achieve voice and personnel location data transmission.
Breaking through the traditional system structure mode, wireless communication and personnel positioning share a set of transmission lines, with a high cost-effective. The system network structure will adopt the star-type combined bus-type network structure scheme with industrial Ethernet as the main dry, take the industrial Ethernet switch as the center point of the star, and adopt the serial connection between the base stations. The base station has both voice communication and positioning functions, and the positioning terminal includes a mobile phone with positioning function. The system adopts the method of intrinsically safe power supply, so that the equipment meets the safety level and technical requirements used in the return airway and work surface.
