Description

Technical Field

[0001] This utility model relates to the field of electronic technology, and in particular to a cable trench intrusion alarm and deterrent device. Background Technology

[0002] As the core node for power distribution and conversion, the safe and stable operation of substations directly affects the reliability of power grid supply. Since substations are mostly built in remote suburbs or rural areas with complex surrounding ecosystems, there is a high risk of small animals accidentally entering the substation. Once they gnaw on the cable insulation or come into direct contact with the live parts of the operating equipment, it will cause accidents such as damage to the cable insulation and discharge of the operating equipment, resulting in power outages.

[0003] Existing preventative measures are passive defenses, only able to be remedied after intrusion traces are discovered or risks are anticipated, through methods such as reinforcement and sealing, and replenishment of poison bait, but unable to achieve proactive prevention and control. As the scale of unmanned substations continues to expand, the drawbacks of traditional manual inspection methods—low efficiency and slow response—are becoming increasingly apparent. Utility Model Content

[0004] In view of this, and considering the actual working conditions, manpower development and equipment deployment costs, this utility model proposes to develop a cable trench intrusion alarm and de-encroachment device. This device integrates infrared and ultrasonic sensors to achieve 24-hour uninterrupted and blind-spot-free monitoring. Upon detecting an anomaly, it immediately alerts staff in real time and uses a multi-module of flashing and buzzing to drive away animals on-site. This effectively fills existing blind spots in prevention and control, significantly improves the operation and maintenance efficiency and safety of unmanned substations, and builds a solid defense for the stable operation of the power grid.

[0005] This utility model provides a cable trench intrusion alarm and expulsion device, which includes a functional module; the functional module includes an intrusion monitoring module, a local expulsion module and a human-machine interaction module; the intrusion monitoring module is connected to the local expulsion module and the human-machine interaction module respectively, and the local expulsion module is connected to the human-machine interaction module.

[0006] The intrusion detection module uses ultrasonic ranging components and pyroelectric infrared sensing components to sense and monitor the movement distance and infrared radiation of animals in the cable trench. If the distance between the animal and the device is lower than the preset distance, or if the infrared radiation of the device changes and the change value of the infrared radiation is greater than the preset value, an intrusion signal will be triggered and transmitted to the local expulsion module and the human-machine interaction module.

[0007] The on-site expulsion module is used to drive away animals with sound and bright light after receiving an intrusion signal, and combines the sound and bright light into an alarm signal and sends it to the human-computer interaction module.

[0008] The human-machine interaction module is used to receive intrusion signals sent by the intrusion detection module and alarm signals sent by the local expulsion module, and to display intrusion alarm information, alarm notification information and equipment status information to the staff.

[0009] Furthermore, the ultrasonic ranging component mainly consists of two piezoelectric ceramic ultrasonic sensors. One piezoelectric ceramic ultrasonic sensor is used to continuously emit ultrasonic signals, and the other piezoelectric ceramic ultrasonic sensor is used to receive reflected ultrasonic signals. The power of the emitted ultrasonic signal is increased by an external signal amplifier, and the reflected ultrasonic signal is amplified. By measuring the time difference between the emitted and received ultrasonic signals, the distance between the ultrasonic ranging component and the reflector is calculated based on the propagation speed of the sound wave. When the distance exceeds a preset distance, an intrusion signal will be triggered.

[0010] Furthermore, the pyroelectric infrared sensing component operates based on the pyroelectric effect. When the pyroelectric material of the pyroelectric infrared sensing component undergoes thermal changes due to infrared radiation, it generates polarization, leading to the accumulation and release of surface charges, thereby generating an electrical signal. Animals emit infrared radiation of a specific wavelength. When an animal moves within the detection range of the sensor, it causes a change in the infrared radiation in the space where the sensor is located. The pyroelectric infrared sensing component converts this change into an electrical signal. After processing and amplification by the internal circuitry, it outputs a high-level signal, thereby triggering the formation of an intrusion signal.

[0011] Furthermore, the local drive-away module uses a buzzer and RGB adjustable lights; the buzzer is mainly composed of an oscillator, an electromagnetic coil, a magnet, and a vibrating diaphragm; after receiving a signal, the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the electromagnetic coil to generate a magnetic field; the vibrating diaphragm vibrates and produces sound under the interaction of the electromagnetic coil and the magnet.

[0012] RGB adjustable lights are used to change the color and brightness of the light by adjusting the proportion of the three primary colors: red, green, and blue. Setting an RGB adjustable light to a high-brightness strobe light can stimulate the animal's vision and achieve a repelling function.

[0013] Furthermore, the intrusion alarm information includes the alarm location and alarm time; the alarm notification information includes whether an alarm signal was issued and whether the intruding animal still exists; and the equipment status information includes whether the device is online and the device's real-time time.

[0014] Furthermore, it also includes a basic module; the basic module includes the main control chip and the power supply module;

[0015] The main control chip is the main control component that handles communication and computing tasks, and it is the foundation for the computing and communication of the intrusion detection module, the local expulsion module, and the human-computer interaction module.

[0016] The power supply module provides a stable voltage to the main control chip, which is the foundation for the intrusion detection module, the local expulsion module, and the human-machine interaction module to be online at all times.

[0017] Furthermore, the basic module is the hardware foundation for realizing the three major functions, ensuring the normal operation of the functional modules and ensuring that the intrusion detection module, the local expulsion module, and the human-computer interaction module can realize their functions.

[0018] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0019] 1. Taking into account the three key aspects of intrusive animal identification and detection, real-time alarm for abnormality detection, and on-site animal removal, the system is based on an Internet of Things (IoT) technology platform and uses infrared sensing technology for uninterrupted monitoring and identification, uploading alarm information to staff and triggering on-site animal removal alarms.

[0020] 2. Based on the Internet of Things (IoT) technology platform, infrared sensing technology is used for uninterrupted monitoring and identification. An appropriate communication network is selected to upload alarm information and drive away alarms on the spot, achieving full coverage of blind spots, full reception of information, and full removal of intrusions.
