Abstract

The invention discloses an image storage type anti-theft device for rural power equipment, belonging to the technical field of power industry equipment management. The image storage type anti-theft device is composed of an infrared ray emitting part and an alarm and evidence taking part, wherein, in the alarm and evidence taking part, an infrared ray receiving module IM transmits the received signals to a CPU (Central Processing Unit), the CPU compares the received information with the information in a FLASH and controls a camera CAM to work, image information is reserved in the FLASH, and simultaneously, alarm information is sent out by a wireless transmitting module GPRS (General Packet Radio Service). The image storage type anti-theft device for the rural power equipment has the following advantage that: the device not only can give an alarm accurately and reduce the probability of wrong alarm and false alarm, but also can shoot on-site images in real time so as to provide strong evidence for later law case detection.

Description

An image storage anti-theft device for agricultural electrical equipment

technical field

The invention belongs to the technical field of equipment management in the electric power industry.

Background technique

At present, the theft of agricultural electrical equipment (such as transformers) often occurs in vast rural areas, which not only brings direct losses to farmers, but also delays farming time and affects agricultural production throughout the year. Since such cases frequently occur in the field and there is a lack of personal and physical evidence, it is often difficult to solve the case even if the police are called to the police. If we can use scientific and technological means to prevent theft and at the same time carry out image forensics, it will greatly improve the efficiency of the public security department in handling cases, and it will also be able to deter criminals and protect agricultural power equipment more effectively.

Contents of the invention

The purpose of the present invention is to use the infrared signal to control the concealed camera device, analyze and process the image data of the scene of the event, and send out corresponding information.

The technical scheme of the present invention is: the invention is composed of an infrared emitting part and an alarm and evidence collection part, wherein the alarm and evidence collection part sends the received signal to the central processing unit CPU by the infrared receiving module IM, and the central processing unit CPU compares the information with the information in the memory FLASH Process and control the work of the camera CAM, the image information is kept in the memory FLASH, and the alarm information is sent through the wireless transmission module GPRS.

Beneficial effects of the present invention: the present invention not only achieves accurate alarm and reduces the probability of false alarms, but also captures on-site images in time to provide strong evidence for future case detection.

Description of drawings

Accompanying drawing 1 is the partial block diagram of the present invention's alarm evidence collection.

Detailed ways

The invention consists of an infrared emission part and an alarm and evidence collection part, wherein the infrared emission part is installed on the protected object, and the infrared emission heads are not less than 3, which are installed in a dispersed manner, emitting different modulation and coding signals, and the directions are all aligned with the alarm and evidence collection part orientation. The alarm and evidence collection part is concealedly installed on the peripheral observation point, which is within 10-50 meters from the protected object. In the alarm and evidence collection part, the infrared receiving module IM sends the received signal to the central processing unit CPU, and the central processing unit CPU demodulates each received signal of the infrared emitting head, and compares it with the information in the memory FLASH. If there is no change, then Continue to receive signals regularly without processing; if the signal received by the infrared receiving module IM changes from the last signal, the camera CAM will be controlled to start working, and the image information will be stored in the memory FLASH. If the received signal changes continuously and cannot be recovered, an alarm message will be sent through the wireless transmitting module GPRS.

The central processing unit CPU connects the timing unit TIM and the infrared lamp LED, and the effect of the infrared lamp LED is to provide infrared illumination for the camera unit CAM at night. Both the infrared emitting part and the alarm and evidence collection part are powered by rechargeable lithium batteries. The infrared emitting head, the infrared receiving module IM, the camera CAM, and the wireless transmitting module GPRS are all commercially available standard products, and there are many models, which will not be listed in detail here.
