Description

technical field

The invention relates to the field of signal transmission, in particular to a wireless transmission system for microseismic monitoring data in rock engineering.

Background technique

In recent years, geological disasters have occurred frequently in our country, causing a large number of human and economic losses. In order to reduce the losses caused by geological disasters to human beings, people use microseismic monitoring systems to monitor the occurrence of geological disasters, analyze them in time and issue geological disaster warnings to people.

In the microseismic monitoring system, it is necessary to monitor many monitoring points in real time. Because the monitoring points of the microseismic monitoring system are scattered and widely distributed, and most of them are set in areas with harsh environments, there is a lack of skilled microseismic information analysts and large-scale background on site. The computer and other equipment required for stress field calculation, so most of the monitoring data need to be sent to the back-end server of the calculation and analysis center in real time for processing. At present, the data transmission methods used in the remote monitoring system are wired and wireless. The wired data transmission method is only suitable for monitoring systems in small areas and small areas, and the maintenance of the lines is large, so it is difficult to guarantee the transmission quality. The wireless transmission method based on GPRS is favored by people because of its long-distance, high-precision, and distortion-free transmission of data. Although some people envisage applying the GPRS wireless transmission method to the microseismic monitoring system, most of them stay in the theoretical research stage, or only design a certain wireless transmission module of the microseismic monitoring system, and there is no complete and overall microseismic monitoring wireless transmission system. .
