Description

Anti-theft alarm for lines not in production

technical field

The utility model relates to an anti-theft alarm, in particular to an alarm for preventing theft of power lines.

Background technique

During the construction of power lines, especially before they are put into production, incidents of wire rod theft often occur. Through the analysis of power line theft incidents, it is found that there are the following characteristics: 1. Theft is easy to occur during the period when the newly erected line is not put into operation; 2. Theft is easy to occur at night, especially in the middle of the night; 3. Theft is easy to occur during the interval between inspections; 4. Theft is prone to occur in remote mountainous areas or sparsely populated places. The theft of power wires will affect the normal construction progress of power facilities and transmission lines, affect the electricity consumption of people's daily life and production, and cause serious direct and indirect economic losses.

In order to prevent the occurrence of line theft incidents, we usually take measures such as increasing the patrol vision, especially strengthening the night patrol vision, to prevent theft incidents. However, since most of the lines are built in sparsely populated areas or remote mountainous areas, night inspections increase the workload of inspectors and increase the traffic safety risks of inspectors.

In order to reduce the workload of the inspectors, reduce the traffic safety risk of the inspectors at night, and discover the stolen lines in time, we conduct research on this topic.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Anti-theft alarm for lines not put into production, including box body 1, intelligent telecontrol terminal 2, battery 5, alarm 3 and battery charging management module, box body 1 including the box body and box cover containing other devices; intelligent telecontrol terminal 2 includes the control system 2-1 and the three-phase electrical interface terminal 2-2. The control system 2-1 is used to detect whether the three-phase power is disconnected to determine whether there is a theft problem, and to control the alarm 3 to send an alarm when the theft problem occurs , and send an alarm message to the power system staff, and the control system 2-1 detects whether the electric quantity of the accumulator 5 is too low at the same time, and reminds the staff to charge in time. The control system 2-1 can be a logic circuit, a single-chip microcomputer, a TTU terminal, etc. In this embodiment, a TTU terminal is used, and the model is WFJ-3303.

The main control module of WFJ-3303 adopts an embedded digital signal processor (DSP) to form a simple and efficient data acquisition and processing system, and adopts surface mount installation technology, which greatly improves the reliability and anti-interference ability of the system; 4-digit switch input It is used to detect the condition of the line and the voltage of the storage battery 5, and to detect whether the battery charging management module has AC power; the circuit of the output part is used to drive the alarm 3.

The three-phase electrical interface terminal 2-2 is three connection terminals, which are respectively connected to the three phases A, B, and C in the transmission line.
