Abstract: To realize theft and leakage pre-warning on long-distance oil pipelines in the blind areas of mobile communication network, the function of Beidou FB3511 module (i.e., satellite short message communication) was used in this paper to design a long-distance oil pipeline pre-warning system with low power consumption which integrates SCM, DSP and Beidou module together. According to the requirements of engineering application on oil pipeline pre-warning system and the characteristics that mobile network link is not available for the data transmission in the blind areas of mobile communication network, the functional requirements of real-time pre-warning, geological location, distributed topology and low power consumption were put forward. And accordingly the program design of the whole system was completed. The hardware platform of pre-warning system is composed of signal acquisition & conditioning module, SCM module, DSP module, Beidou short message module and power supply module. The working process of the whole system was described in detail. It is shown from its field test that this system can provide pre-warning on theft and leakage of long-distance oil pipelines in the blind areas of mobile communication network, and its indicators satisfy the design requirements, e.g. locating precision, system delay and average power. This system is of great engineering significance to ensure the operation safety of long-distance oil pipelines in the blind areas of mobile communication network.
