Description

technical field [0001] The present invention relates to a high-speed remote wireless transmission device based on IEEE 802.11a wireless transmission protocol, Wi-Fi, WLAN wireless access technology and microwave communication technology, in particular to a high-speed remote wireless transmission device and its method for on-site monitoring of geotechnical engineering . Background technique [0002] Geotechnical engineering monitoring is an important part of geotechnical engineering. It plays an important role in all stages of design, construction and operation. It is an indispensable technical measure to ensure the safety of geotechnical engineering construction and operation. It is a key link in the design method and an important basis for construction and operation technology decisions. In recent years, safety monitoring has been widely used and developed in water conservancy and hydropower, industrial and civil construction, railway transportation, coal mines, and milita...

AI Technical Summary

Problems solved by technology

However, the GPRS and CDMA technologies currently used in wireless monitoring technology have obvious shortcomings of insufficient bandwidth. The data transmission rate is only a few Kbps to a dozen Kbps, and the video transmission is only a few frames per second or even impossible to transmit, especially in remote areas far from the base station. The signal is weak, the connection and transmission rate are significantly reduced, and it is prone to breakpoints and wireless reception dead spots

Even if wireless telemetry is realized, the effect is unsatisfactory
