Abstract:

Deformation monitoring is an important basis and technical measurement to ensure the project construction and operation, it perfects the geotechnical engineering design method and plays an important role in project construction and operation stage. Traditional manual monitoring method is difficult to ensure the monitoring frequency and result because of its time-consuming and hard sledding. Based on the public telephone network and the GPRS network, one kind of digital monitoring wireless transmission method and equipment has been designed for automatic monitoring and it is especially suitable for difficult condition automatic remote measuring. to establish and control The data acquisition instrument through public telephone network data acquisition communication facility is established and controlled by using master control computer and necessary control software, the monitoring result to the master control computer through the GPRS network wireless transmission is returned. From this method, the remote measuring for distortion numerical monitoring in geotechnical engineering has been accomplished. The apparatus is mor accurate and stable than the traditional method for its simple structure, high precision, automaticity , stability and low error rate. The deformation monitoring in geotechnical engineering is no longer difficult and arduous.
