Specification :

A. System principle & composition:
The system is made up of alarm receiving center ( including SMS alarm receiving host, a computer & a set of software) and several alarm hosts in the monitored places. The alarm hosts are installed on the poles beside the power transformers. Once the infrared detector detects someone intruder the defense zone, the horn will issue 110 dB sound to warn the intruders which have entered the dangerous zone.
Before stealing the power transformers, the thieves will cut the power lines. The alarm host can detect which line of the three phase lines is cut and immediately alarms to the alarm receiving center and mobile phones through GSM SMS alarm. The alarm receiving center transmits the data to the computer when receives an alarm. After the analytical judgment by the alarm receiving software, voice alarm will happen in the alarm receiving center. The computer shows the alarm date, time, extensions, the broken transformer & the possible fault phase electric. At the same time, the digital map displays the actual location of the alarm transformer and the information of fault phase electric. The alarm data will be recorded automatically for inquiries. Once the operator on duty gets the alarm information, he will immediately send the police & the relevant people to inspect the situation & handle the relevant issues.
