Join in marriage net line fault positioning system based on GPRSSMS mixed communication

The utility model discloses a join in marriage net line fault positioning system based on GPRSSMS mixed communication, including setting up the distribution intelligent control unit on built on stilts or cable run, near and the corresponding GPRS DTU who sets up distribution intelligent control unit, each distribution intelligent control unit is respectively through the RS serial communication module to GPRS DTU conveying control data, the system still includes network server and remote monitoring center, GPRSDTU loops through the removal GPRS network, the internet is to network server conveying control data, network server will monitor data transmission to remote monitoring center, distribution intelligent control unit includes that alternate short -circuit fault surveys the module and earth fault surveys the module, alternate short -circuit fault surveys the output and RS serial communication module electric connection of module and earth fault detection module. This system can improve stability, reliability and the application scope of system greatly, avoids loss of data, and phenomenon emergences such as inaccurate are failed to report, are fixed a position to the trouble, has good popularization and application and is worth.
