Using computer technology, communication technology and network technology, it is clear that the application of coal and non-coal companies' communication systems in practice is obviously necessary and timely. It is also a requirement for the management innovation and technological progress of coal management departments, thereby further improving coal The overall management level of safety production. This is not only important for coal production, but also has important reference value in the same industry in the country. In order to meet the requirements of scientific production and scientific management of modern enterprises, Shenzhen Network Lianyuntong Software Technology Co., Ltd. is a manufacturer of equipment. Based on the mine customer's needs and the mine communications hidden in the mine, ZigBee/IEEE 802.15.4 network technology was independently developed. A high-performance wireless communication system and terminal equipment are presented, and a safe, reliable, economical, advanced, and efficient communication system solution is proposed.
The overall structure of the system:
The mine wireless communication system is a network main body composed of a network switch, a voice gateway and an optical fiber. A number of mining intrinsically safe reader substations are established at the mine or mine according to the communication distance, and the underground mine roadway is covered by a wireless local area network to use the mine. Intensive wireless local area network with intrinsically safe mobile phones enables functions such as voice scheduling, downhole wireless communication, wireless personnel positioning, short message sending and receiving, personnel identification, image processing, and data analysis in various jurisdictions downhole. The department provides scientific evidence for decision-making, eliminates potential accidents to the greatest extent and eliminates accidental safety accidents.
System features: Small amount of communication data, low data transmission rate, small distribution range, low cost and power consumption, easy installation and use.
The main function:
â—Wireless phone calls between Inoue and underground cable telephones and mobile phones â—Single-message and single-send â—Attendance data management â—Wireless personnel positioning â—Continuous 2-hour conversation between mobile phone and mobile phone after disconnection â—Able to meet 7-hour talk time after charging
Most laptop power adapters are suitable for 100 to 240 VAC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and host connection, so you can reduce the size and weight of the host, only a very small number of models built-in power supply in the host. In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, which is the so-called "travel power adapter", if the city voltage is only 110V of the country , This feature is very useful, and some parallel notebook is only sold in the country of origin, there is no such compatible voltage design, or even only a single input voltage of 110V, 220V in China under the voltage plug will burn.
