Transformer anti-theft system principle and composition: transformer anti-theft system

The power transformer anti-theft alarm system developed for the actual situation is mainly used for power line and transformer anti-theft alarm. Its characteristics are: no distance limitation, no quantity restrictions, no weather influence, only one alarm center can be set up. The microcomputer is equipped with the alarm center software, which can display the actual location of the alarm transformer and the fault line in an electronic map, and can record the alarm time in real time. After receiving the printer, you can print the data, alarm date, time and extension number for future reference, and reduce the investment cost. It has the characteristics of practical function, good quality, stable and reliable work, and is suitable for outdoor environment use. It is widely used in the safety protection of all outdoor electrical equipment such as electric power, petroleum and mining.

Principle and composition of transformer anti-theft system: system principle and composition

1, system principle:

The wireless monitoring alarm host is installed on the pole of the monitored power line or next to the transformer. Once the power line or transformer is stolen, three-phase disconnected or power-off, the monitoring alarm host immediately detects and sends a warning to the GSM receiving host via wireless GSM short message and voice. After receiving the alarm signal, the receiving host transmits the data to the microcomputer. The microcomputer analyzes and judges the alarm host and the line that may be faulty after receiving the alarm software. The screen displays the alarm date, time, alarm extension number, fault transformer and possible fault line. And display the actual location of the alarm transformer and the fault line by electronic map, and store the alarm data in the database for inquiry. After the duty leader got the alarm, he immediately sent police to the scene to check the situation and deal with the relevant issues.

2. System composition

The system consists of an alarm alarm host, a GSM receiver host, and a microcomputer (an alarm software) to form an anti-theft alarm system.

(1) Transformer anti-theft alarm host

GSM (900M/1800MHz) wireless cellular network control alarm host uses GSM short message data transmission mode and voice function platform to complete remote transmission and control of intelligent alarm data. This series of hosts has the characteristics of practical function, good quality, stable and reliable operation, and adapts to outdoor. It is widely used in the safety protection of all outdoor electrical equipment such as electric power, petroleum, mining, etc. Due to the wide coverage of GSM global wireless mobile communication network signal, it realizes the convenience and flexibility of low-cost and high-quality ultra-long distance. The intelligent wireless control and alarm solves the limitations of fixed-line wired or wireless high-power alarm control.

(1) GSM receiving host

The GSM SMS and voice receiving host mainly completes the GSM SMS data and voice dialing conversion to the standard RS232 serial communication protocol function, and connects to the computer through the RS232 serial port to form the alarm center.

(2) Alarm center software

The alarm police software is a professional integrated alarm information receiving platform. It is the first in China to use GSM network short message (SMS) and voice and fixed telephone network voice to receive alarm information. It is used in public security and security duty alarm centers. It integrates functions such as alarm reception, user database, GSM short message, alarm voice telephone alarm, and instant print alarm data. Its display interface is intuitive, image and friendly, without professional operation knowledge, and no need for professional operators. Learning fast, easy to use.
