Zijin Mining Group Co., Ltd. started from the Zijinshan Gold Mine in Fujian Province in 1993. After 21 years of development, it has become a large state-owned mining group focused on the exploration and development of gold and metal mineral resources. Zijin Mining adheres to the principle of "life first, environmental protection first", and safe production is the lifeline of its enterprise. In order to better protect the safety of operating personnel, wireless remote monitoring of mining areas has also become the best helper for enterprises.

无线远程监控 地理位置的选择是很重要的,如果有遮挡就必须用加中继的方式来避开遮挡物。 Because the geographical environment of the open area is more complicated, there will be many trees in the mountains. Therefore, it is very important to choose a wireless remote monitoring geographic location in the open area . If there is cover, you must use a relay to avoid the cover. Thing.


On-site demand situation:

In the mining area, the signals of 12 high-definition network cameras need to be transmitted back to the monitoring center, and there is cover in the middle. The wireless monitoring equipment needs to be relayed twice to return to the monitoring center. The distance between the monitoring point and the mountaintop is 500 meters The distance between the peak transfer point and the tower is 5 kilometers, and the distance from the tower to the monitoring center is 5 kilometers.


Demand solution:

There are eight points of signals from the front-end network camera. -5830F Wireless monitoring equipment to launch, there are four points is that two cameras together to share two LA -5830F Wireless monitoring equipment to transmit, the transmitting end needs a total of ten LAs -5830F 作为发射; Wireless monitoring equipment as a transmission;

The first transfer point on the top of the mountain uses two LA-5810-N wireless bridges + two 90-degree dual-polarized plate antennas for reception. The signals of the two wireless bridges are forwarded by the switch and then another LA-5810 -N wireless bridge + 5.8G 29dbi dual polarized dish antenna to transmit;

One LA-5810-N wireless bridge for the second transit point tower + 5.8G The 29dbi dual-polarized dish antenna is used for receiving. The signal of this wireless bridge is forwarded by the switch and then another LA-5810-N + is used. 5.8G 32dbi dual-polarized dish antenna as the transmission (the transmission distance of this device is Twenty kilometers );

One LA-5810-N + for monitoring center 5.8G The 32dbi dual-polarized dish antenna is used for receiving, and the signal of this wireless bridge can be directly sent to the digital matrix or hard disk video recorder (NVR) storage and display.

  Features and advantages of wireless remote monitoring

This wireless monitoring system uses 802.11A / B / G / N and OFDM / QPSK modulation technologies have the characteristics of long transmission distance, high receiving sensitivity, long non-line-of-sight transmission distance, and clear and smooth images. It mainly solves the real-time video transmission of mobile and wireless remote monitoring.

The advantages of its wireless monitoring equipment are reflected in the following aspects: easy installation and construction, low comprehensive cost; flexible networking, good scalability, plug and play; good system stability, high reliability; low maintenance costs; high bandwidth , Strong compatibility; fast networking, strong manageability;
