GSM network electric power device alarm system realizes the remote transmission and control of the intelligent alarm data by using GSM short message transmitting mode and the voice function platform. This alarm system is mainly applied to the prevention of cutting, stealing, and destroying of the power supply device and the circuitry of the electric wires and transformers in the electric power system. The mainframe adopts sealed Aluminum Die Casting shell. With good waterproof ability, practical, good quality and stable and credible functions, it can be used in various outdoor environments, like the security protection of the outdoor electric power device working at power station, oil, and mine and so on. It can work independently or be together with the police center network. The functions are as follows:
1. GSM short message warning is direct and reliable. The transmission distance is not restricted.
2. It can detect and submit very correctly about the abnormal circumstances after three-phase testing on the electric power supply circuitry.
3. It can be mounted with sensors which can alarm on the destroying and moving of the power supply transformer.
4. It can set 6 groups of alarming numbers which can get through with police by common cell phone or the computer in the police center.
5. Users can set some related information by short message.
6. It can set mainframe state inquiry everyday.
7. There will be message hints when the battery is in low volts.
8. Sealed aluminum die-casting shell offers good waterproof quality. It is suitable for outdoor installation.
9. The whole system can self protect when the electricity is cut off. When the wire is destroyed or cut off for other reasons, the backup battery will play an important role and can be charged when the electricity is available.
