The slope stress monitoring of the opencast mine is important to safe production in opencast coal mine. The purpose of the thesis is to design and implement a set of slope stress monitoring with wireless remote monitoring technology. According to the analysis of technology of the slope stress monitoring, it selects anchor dynamometer to monitor slope data; It raises the remote transfer program based on short message service of GSM network as the core technology; It chooses microprocessor AT89S52 as the main control chip in order to design the sub-node stress monitoring circuit, which completes the field data acquisition, monitoring and transmission; Based on formulating the data communication protocol, it accomplishes remote transmission of data through the application of MC35i SMS; it achieves the sub-node manual and automatic inquiry, the list display of database and graphic curve display via the designing of management software of the central monitoring computer. The circuit of hardware and software procedure after debugging comply the remote acquisition, transmission and management. The layout has been verified as a reliable and effective set of opencast-coal-mine slope stress monitoring system with wireless remote monitoring technology through eight-month field operation.
