Overview:
The safety of China’s coal mining industry has always been the heartache of the Chinese government. Coal is an important energy resource in my country. However, my country’s coal industry has long remained at the level of manual mining, with low production efficiency and many potential safety hazards, such as gas explosions, underground water seepage, etc. Accidents happen frequently. Because the general coal mines are remote in geographic location and complex terrain, the use of wired network construction investment is large, and network wiring is difficult. Wireless has the characteristics of flexible network deployment and faster transmission speed, which can be used as the best supplement to wired networks.
One way to use GPRSWireless communication terminalThe underground data is wirelessly transmitted to the main station server and industrial computer in the control center computer room to realize the real-time acquisition, processing, storage, display and alarm of the underground data. Data including working face images, coal seam humidity, air gas concentration, and fan operating status can all be displayed in the monitoring center in real time. At the same time, real-time monitoring and alarming of the gas content in the mine can be realized by the control center.
System Features:
1) H7000 protocol family, including TCP, PPP, TELNET, HTTP, SMTP, Pop3, etc. The embedded TCP/IP is easy to use, has multiple choices of functional interfaces, supports always-on, flexible configuration, small size, convenient upgrade, strong scalability, strong anti-interference and other characteristics.
2) The hybrid access method of the access method further improves the security of the system.
a) The client software with the function of two-stage virtual dialing. Using VPN for isolation can encrypt and protect the entire data transmission process, effectively avoiding illegal intrusion.
b) For binding, only the SIM belonging to the designated industry and the SIM of ordinary mobile phones.
c) and password to further enhance the security of the system.
d) Encrypt and protect the entire data transmission process.
Network access security authentication mechanism: firewall software is used to set up network authentication and security protection functions to ensure system security.
typical application:
The H7000 wireless DDN system has many advantages such as stable work, easy maintenance, and upgradeability. At the same time, Shenzhen Hongdian Technology Development Co., Ltd. will provide you with comprehensive after-sales service and support. Aiming at the application field of coal mine monitoring system, Shenzhen Hongdian Technology Development Co., Ltd. wholeheartedly provides customers with effective wireless communication solutions for data communication, which will surely have a broader development and application prospects in this industry.
