Abstract: By adopting the advanced monitor instrument and the modern wireless communication technology, a set of long-distance wireless datum transmission system for landslip monitoring has been developed, which is made up of three major parts: control center, GSM network and leading terminal station. One of the system's ends joins the monitoring instrument fixed on the monitoring point in landslip, the other end links with control center. The one-chip computer controls and gathers and changes with A/D the parameter from sensor of the leading terminal station, the receiving and dispatching module (TC35) conveys the data to the control center by GSM after dealing with, in order to realize the tasks of data transmission, data management, establishment of monitoring model, dispatching of pre-warning message; besides it could analyze and process the monitoring data, for researchers to use. This system could be supplied by the solar energy, suitable for the remote districts especially. Through modeling in room, the function of the system is stable; the data is transmitted promptly and accurately.
