The invention discloses a fixed clinometer system. The fixed clinometer system comprises a group of sensors, a data acquisition system, a data transmitting system and a data receiving system, wherein the sensors are connected with the data acquisition system; the data acquisition system is connected with the data transmitting system; the data transmitting system transmits data to the data receiving system through general packet radio service (GPRS); and the sensors are connected in series. Through the adoption of serial connection mode of the sensors, each sensor is prevented from being directly connected to the data acquisition system, so many leads are avoids and inconvenience of mounting and maintenance is avoided. Through the adoption of serial connection mode of the sensors, the system supply power to the sensors step by step and at different time to finish acquisition and upload signals, so that reliable transmission of the signals is guaranteed, the sensors in the sampling process can truly obtain the power, the whole system has minimum power consumption, and the system is suitable for the environment of field power supply by batteries.
