Embodiment Construction

[0010] A sensor-based cable anti-theft monitoring system is mainly composed of a carrier module 1, a Hall current detection circuit 2, CDMA3, LPC21314, a liquid crystal display module 5, a keyboard module 6 and a reset circuit 7, and is characterized in that: the carrier Module 1, Hall current detection circuit 2 and CDMA3 are all connected to LPC21314, and liquid crystal display module 5, keyboard module 6 and reset circuit 7 are all connected to LPC21314.

[0011] The carrier module is selected from the PLT232 carrier module, and the line anti-theft detector is installed at the power cable tap point in the transformer station area. It is mainly composed of a power supply circuit and a gateway PLC module. Its function is to send and receive carrier signals and perform carrier communication. Sensing with Hall sensors provides the prerequisites for the application.

[0012] The Hall current detection circuit 2 uses a Hall current sensor of the SP4 series, and selects an AC-DC p...

Abstract

The invention discloses a cable anti-theft monitoring system based on a sensor, and belongs to the technical field of sensor detection. The system is mainly composed of a carrier module, a Hall current detection circuit, a CDMA, an LPC2131, a liquid crystal display module, a keyboard module and a reset circuit. The system is characterized in that the carrier module, the Hall current detection circuit and the CDMA are connected with the LPC2131; the liquid crystal display module, the keyboard module and the reset circuit are connected with the LPC2131. The system is easy to maintain, popularizeand use, low in cost and the like, and opens up a new way for safe operation of a low-voltage power cable and improvement of reliability and maintainability of the cable alarm system.

Description

technical field [0001] The invention relates to a sensor-based cable anti-theft monitoring system, which belongs to the technical field of sensor detection. Background technique [0002] Cable theft is one of the most serious disasters in the power system. In recent years, cable theft accidents have occurred frequently, causing major economic losses and potential safety hazards to the country. For this reason, it is very important to improve the reliability and timeliness of the low-voltage distribution cable anti-theft alarm system. The research and application goal of multi-sensor data fusion theory is to intelligently synthesize data and information from multiple information sources to produce more accurate, more complete and more reliable descriptions and judgments than single sensors. The extremely extensive application background is a hot research field in the scientific and technological circles. The invention develops a sensor-based cable anti-theft monitoring syst...
