(1.1) Communication host: composed of GSM/GPRS communication module, short-distance wireless communication module, power low-voltage carrier module, artificial intelligence power grid status recognition module, sound and light alarm module, etc. Due to the intensive information in the station area and the sharing of data resources, the communication host system has strong information intelligent identification, intelligent decision-making and control capabilities. The communication host completes information collection, processing, control, exchange and remote data communication within the station area through the GSM/GPRS network (uplink) of the GSM/GPRS communication module and the wireless ad hoc network (downlink) channel of the short-distance wireless communication module.

(1.2), communication extension: mainly composed of three-phase four-wire artificial intelligence grid status identification module, carrier signal receiving module, short-distance wireless communication module, intelligent protection module, sound and light alarm module, etc. Signal identification, tracking and monitoring and alarm tasks for partial lines.

(1.3) The distribution transformer detector is fixed on the top of the transformer cover with strong magnetic steel suction. Usually, the circuit is in a dormant state when the transformer is in normal operation. Send an alarm signal to the communication host through the communication extension.

(1.4), the line detector is a unit device for protecting key line sections. It is composed of wire sensors, interface filters, single-chip IC chips and communication extensions. It usually works in a semi-dormant state. When the power line is broken, it is fixed on the power line. The sensor will send a wireless alarm message to the communication host due to imbalance.

(2) Features of the anti-theft subsystem in the station area

(2.1), convenient and flexible networking, high cost performance, and low operating costs. Taking the sub-system of the distribution station area as the monitored unit, the protection covers all the power facilities in the station area, and the unit equipment in the adjacent station area can also be combined into a subsystem (the capacity of the GSM communication host and the communication distance of the ad hoc network allow Down).

In order to ensure the reliability of the system, the system is distributed from the sensor to the channel, and the microcomputer artificial intelligence IC chip is embedded in the distribution. Regardless of the operating state of the power grid or the weather conditions of the natural environment, when the power facilities are damaged or stolen, it can intelligently analyze and make a correct judgment, and send out a "stolen alarm" signal in time, and will never falsely or refuse to call the police. Or miss the alarm.

If the system equipment is "sub-healthy" or malfunctions, the system will send out a "maintenance alarm" signal in advance for timely repair. If the GSM/GPRS channel fails or is blocked, the system will immediately switch to the "self-rescue" working mode. Once the channel returns to normal, it will immediately report to the management and application layer about the event and the power facilities in the time period.

3. Cable and cable trench anti-theft subsystem

With the advancement of the urbanization process, 10KV lines are gradually transferred from the ground to underground, and the laying project is divided into two methods: 10KV high-voltage cable trench and 10KV high-voltage buried cable.

(3.1), 10KV cable trench anti-theft subsystem consists of communication host, solar panel, communication extension, sensor and composite channel bus. When someone invades the cable trench and touches the smart sensor, the communication host will send a stolen warning message to the intrusion location number. And when other small animals enter the cable trench, the sensor intelligently filters the signal and intelligently recognizes it without sending out an early warning message. The device is moisture-proof, flood-proof and vandal-proof, and the power supply can be taken from solar panels or street lamps.

When the line inspector presses the "wireless line inspector notification device" carried with him under the iron tower (50M range), the "power transmission monitoring and management computer" will display the line inspector's name, inspection location and time.

(2.3) Due to lightning strikes and insulator fouling, the insulators between the tower and the transmission line will cause flashover faults. The conventional inspection method is to check tower by tower manually, which is time-consuming, laborious, expensive, and economically lost. Therefore, automatic monitoring of transmission line leakage The current limit alarm is very necessary.
