Description

Technical Field

[0001] This utility model relates to the field of rodent control, and in particular to a real-time rodent control monitoring device. Background Technology

[0002] In agricultural production, warehousing and logistics, and residential settings, rampant rodent infestations can cause numerous problems such as food loss, equipment damage, and the spread of diseases. Efficient rodent control and real-time monitoring of rodent control status have become urgent needs to ensure a safe and clean production and living environment.

[0003] Traditional rodent-catching methods, such as sticky traps and ordinary mousetraps, have obvious drawbacks: on the one hand, they cannot provide real-time feedback on the rodent-catching status, requiring staff to conduct manual inspections and confirmations, which is time-consuming and labor-intensive, and makes it difficult to know the rodent-catching situation in a timely manner; on the other hand, they lack accurate detection and intelligent control, either missing the opportunity to catch rodents due to insensitive triggering, or the active defense modules such as electric shocks are poorly controlled, which are prone to false triggering or failures that cannot be detected in time. Moreover, in complex environments such as humid conditions, the circuit is prone to short circuits and damage, affecting the stability and service life of the device.

[0004] Although some intelligent mouse-catching devices have attempted to incorporate sensors and communication modules, they still fall short in terms of system integration and functional refinement. For example, sensor detection is easily affected by ambient light, resulting in poor detection accuracy; capacitor charging and discharging modules lack a robust protection mechanism, making them prone to burning out during short circuits; fault diagnosis relies solely on simple indicator lights, without combining programming to achieve accurate fault type identification and code recording; and wireless communication is mostly unidirectional, with limited alarm methods at the receiving end, making it difficult to meet the rapid response requirements in various scenarios.

[0005] Therefore, there is an urgent need to develop a real-time rodent monitoring device that integrates high-precision detection and intelligent features. With functions such as control, safety protection, real-time communication, and fault diagnosis, it relies on the PLC control core to optimize sensor detection logic, capacitor charging and discharging process, and wireless alarm mechanism, adapting to complex environments, improving rodent trapping efficiency and device reliability, and solving many pain points of traditional and existing equipment. Summary of the Invention

[0006] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0007] A real-time rodent monitoring device, comprising: PLC control module: The Mitsubishi FX2N-14MR industrial control board is used as the control core. The industrial control board is used to receive sensor signals and output control commands. It is programmed with GXDeveloper software to implement initialization, infrared detection, electric shock control, alarm processing and fault diagnosis functions. Photoelectric sensor module: The E3F-DS30C photoelectric sensor is selected to detect whether a mouse has entered the electric shock area. The sensor generates a detection signal by emitting and receiving changes in light and transmits it to the PLC control module. The capacitor bank charging and discharging module consists of 16 CBB capacitors arranged in a 4×4 matrix, supports 12V DC power supply, and has the ability to generate 1.5KV high voltage through instantaneous discharge. The module is electrically connected to the PLC control module and is controlled by PLC commands to control the charging and discharging process. Wireless communication module: integrates low-power wireless serial communication technology, used to send an alarm signal to the receiver after the capacitor bank discharges. The module is connected to the PLC control module to realize real-time transmission of the mouse trapping status. Safety protection module: Includes an insulating protective layer and a moisture-proof circuit design. The insulating protective layer covers the high-voltage discharge area, and the moisture-proof circuit uses sealant to encapsulate key components to prevent moisture damage. The circuit short-circuited in a humid environment.

[0008] As an improvement, the I / O allocation of the PLC control module includes: a power start switch connected to input port X0, a photoelectric sensor connected to input port X1, a communication switch input connected to input port X2, a capacitor discharge device connected to output port Y0, and a communication switch output connected to output port Y1.

[0009] As an improvement, the detection logic of the photoelectric sensor module is as follows: when a mouse enters the detection range, the sensor outputs a high-level signal to the X1 port of the PLC, triggering the PLC to control the Y0 port to output a high level, so that the capacitor bank discharge module releases high-voltage electric shock.

[0010] As an improvement, the discharge control process of the capacitor bank charging and discharging module is as follows: after receiving the sensor signal, the PLC controls the capacitor bank to charge to the set voltage. When a mouse is detected in the electric shock area, the capacitor bank is triggered to discharge instantaneously for 2 seconds.

[0011] As an improvement, the wireless communication module uses 433MHz frequency band wireless transmission. When the capacitor bank discharge module performs the discharge action, the PLC controls the Y1 port to output a signal, triggering the wireless module to send mouse alarm information to the remote terminal.

[0012] As an improvement, a fault diagnosis module is also included. This module uses PLC programming to detect photoelectric sensor faults, abnormal capacitor bank voltages, and wireless communication interruptions. When a fault is detected, the PLC controls the alarm indicator light to flash and records the fault code.

[0013] As an improvement, the program of the PLC control module includes a power-on initialization subroutine, which uses the M8002 special relay to generate a pulse signal when the PLC is powered on, to initialize the status of each register and output port.

[0014] As an improvement, the photoelectric sensor module has a detection distance of 30cm, adopts the through-beam optical detection principle, and reduces ambient light interference through a filter to ensure detection accuracy.

[0015] As an improvement, the capacitor bank charging and discharging module supports no-load and short-circuit protection. When a short circuit is detected at the output terminal, the PLC controls the disconnection of the charging circuit to prevent the capacitor from overheating and burning out.

[0016] As an improvement, the receiving end of the wireless communication module is equipped with an alarm notification device, including an audible and visual alarm and a text message push function. When an alarm signal is received, the audible and visual alarm is triggered simultaneously, and a mouse-catching notification text message is sent to a preset mobile phone number.

[0017] Beneficial effects I. Precise and efficient rat trapping Accurate detection: The photoelectric sensor adopts a through-beam principle and a filter design. The 30cm detection distance is suitable for the electric shock area, effectively reducing ambient light interference, accurately identifying mouse intrusion, avoiding false alarms and missed detections, and improving the accuracy of mouse trapping.

[0018] Controllable electric shock: The PLC-coordinated capacitor bank charging and discharging module has a clear charging-discharging process (charging to the set voltage and 2-second instantaneous high-voltage discharge), which ensures the rodent extermination effect while avoiding energy waste and excessive capacitor loss, and efficiently completes the rodent trapping action.

[0019] II. Intelligent Monitoring and Interaction Real-time status feedback: The wireless communication module is based on the 433MHz frequency band. The alarm is triggered synchronously with the discharge. The receiver provides dual reminders of sound and light and SMS, so that users (homes, warehouse managers, etc.) can know the results of the rodent trapping in time, eliminating the need for manual inspection and improving management efficiency.

[0020] Fault self-diagnosis: PLC programming enables fault detection of sensors, capacitor banks, and communication systems, recording fault codes and flashing indicator lights to accurately locate problems, reduce maintenance difficulty and time costs, and ensure long-term stable operation of the device.

[0021] III. Safety and Environmental Adaptation Hardware protection: capacitor bank short circuit / no-load protection, high-voltage area insulation protection layer, and moisture-proof packaging for critical circuits. From circuit safety to physical protection, it avoids electric shock to personnel and burnout of components, and is suitable for complex environments such as humid (such as kitchens and warehouses) and dusty environments.

[0022] Program safety: The power-on initialization subroutine resets the system state to ensure stability on each startup; I / O ports are allocated reasonably, and instruction and signal interactions are clear, reducing program conflicts and improving device reliability.

[0023] IV. Deployment and Usage Advantages Flexible deployment: The device is compatible with 12V DC power supply batteries and power adapters, and features a compact 4×4 capacitor matrix layout. It is small in size, easy to install, and can be quickly deployed in scenarios such as home kitchens and outdoor storage.

[0024] Highly user-friendly: Simple control via switches (power supply, communication), fault codes and alarm prompts lower the barrier to operation and maintenance, allowing even non-professionals to get started quickly and reducing usage and maintenance costs.

[0025] In summary, this device optimizes the entire process from core rodent-catching functions to safety and operation and maintenance, precisely addressing the pain points of traditional rodent-catching methods such as "poor detection, slow feedback, difficult maintenance, and unsafety." It has high efficiency and practical value in multiple scenarios such as homes, agriculture, and warehousing, balancing functionality, safety, and ease of use, and contributing to intelligent rodent control. Attached Figure Description

[0026] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, in which: Figure 1 This is a system schematic diagram of the device according to the present invention. Detailed Implementation

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] This real-time rodent monitoring device uses a Mitsubishi FX2N-14MR industrial control board as the core PLC control module to build the overall control system. Each functional module works in conjunction with the PLC control module. The specific connections and interactions are as follows: As the core hub, the PLC control module receives detection signals from the photoelectric sensor module, command signals from the power start switch and communication switch; it outputs discharge control signals to the capacitor bank charging and discharging module, and alarm trigger signals to the wireless communication module. It also integrates functions such as fault diagnosis and program initialization, and works with the safety protection module to ensure the stable operation of the device.

[0029] Hardware and Programming Fundamentals: The Mitsubishi FX2N-14MR industrial control board was used, and the program was written using GXDeveloper software. The program covers subroutines for functions such as power-on initialization, infrared detection, electric shock control, alarm handling, and fault diagnosis. For example, the power-on initialization subroutine uses the M8002 special relay to generate a pulse signal at the moment the PLC is powered on, clearing or setting the initial values ​​of various registers (such as registers used to store sensor status, capacitor voltage values, etc.), and simultaneously initializing the output ports (Y0, Y1, etc.) to low level to ensure that the device's startup state is controllable.

[0030] I / O allocation and signal interaction: The power start switch is connected to input port X0. When the operator closes the switch, port X0 receives a high-level signal, triggering the PLC's internal program to start running; the detection signal from the photoelectric sensor module is transmitted to input port X1; the communication switch... The input switch X2 is used to manually control whether the wireless communication alarm function is enabled (e.g., during equipment debugging or in specific scenarios where alarms are not required, disconnecting the communication switch input will cause port X2 to be at a low level, and the PLC will not trigger the wireless alarm process). Output port Y0 is connected to the capacitor bank charging and discharging module to output the discharge control signal; output port Y1 is connected to the wireless communication module to output the alarm trigger signal.

[0031] Hardware Selection and Principle: The E3F-DS30C photoelectric sensor is selected, operating on the principle of through-beam optical detection. This sensor includes a transmitter and a receiver; the transmitter continuously emits light of a specific wavelength, which the receiver receives. Its detection distance is set at 30cm, effectively covering the electric shock area of ​​conventional mousetraps. To reduce interference from ambient light (such as sunlight and indoor lighting), the sensor is equipped with a filter, allowing only light of a specific wavelength (matching the wavelength of the emitted light) to pass through, ensuring detection accuracy.

[0032] Detection Logic and Signal Transmission: When a mouse enters the 30cm detection range, it blocks the light emitted by the transmitter to the receiver. The receiver experiences a sudden change in light intensity, triggering the sensor's internal circuitry and outputting a high-level signal to the PLC's X1 port. The PLC program monitors the X1 port status in real time; once a high level is detected, it immediately initiates the electric shock control process. The Y0 port is controlled to output a high-level signal to prepare for the discharge of the capacitor bank charging and discharging module.

[0033] Hardware Composition and Power Supply: The capacitor bank consists of 16 CBB capacitors arranged in a 4×4 matrix, powered by 12V DC. This matrix arrangement ensures sufficient capacitor capacity and discharge capability while facilitating circuit layout and heat dissipation. The 12V DC power supply is compatible with common low-voltage power supply scenarios (such as power supply via batteries or low-voltage power adapters), making it easy to deploy the device in different environments (such as temporary field storage sites, home kitchens, etc.).

[0034] Charge / discharge control process: When the PLC receives a signal from the photoelectric sensor module via port X1... Upon receiving a high-level detection signal, the PLC first controls the capacitor bank to enter the charging phase. The internal charging circuit charges the capacitor bank to a set voltage according to a preset program (during charging, the PLC can monitor the capacitor voltage in real time via a voltage detection circuit to ensure that the discharge requirement is met). When a mouse is detected again continuously in the electric shock area (confirmed by a signal continuously output by the photoelectric sensor module or in conjunction with other auxiliary detection methods), the PLC immediately triggers a momentary discharge of the capacitor bank, with the discharge duration precisely controlled to 2 seconds. This discharge duration has been tested and found to effectively stun or eliminate the mouse while avoiding excessive capacitor wear or energy waste due to prolonged discharge.

[0035] Safety protection mechanism: The module supports no-load and short-circuit protection functions. The device has a built-in detection circuit to monitor the status of the capacitor bank output in real time. When a short circuit is detected at the output (such as insulation failure between electrodes due to a humid environment, short circuit due to external metal objects, etc.), the PLC quickly controls the disconnection of the charging circuit, stopping the power supply to the capacitor bank to prevent the capacitors from overheating and burning out due to continuous high current charging, thus ensuring the safety and service life of the device hardware.

[0036] Communication Technology and Frequency Band: It integrates low-power wireless serial communication technology and uses the 433MHz frequency band for wireless transmission. This frequency band has advantages such as strong diffraction capability, moderate transmission distance (stable transmission distance of tens to hundreds of meters in indoor environments, meeting the spatial requirements of scenarios such as homes and warehouses), and relatively low susceptibility to interference, making it suitable for the short-range real-time communication needs of rodent traps.

[0037] Alarm Triggering and Information Transmission: When the capacitor bank charging and discharging module performs a discharging action, The PLC controls the Y1 port to output a high-level signal, triggering the wireless communication module to operate. The wireless communication module modulates the pre-set mouse alarm information (including basic data such as device number and mouse-catching time, which can be pre-encoded and stored via the PLC program) and transmits it at a frequency of 433MHz. The segment signal is sent to the remote terminal.

[0038] Receiver Functionality: The receiver is equipped with an alarm notification device, including an audible and visual alarm and SMS push notification functionality. Upon receiving an alarm signal from the wireless module, the receiver first triggers the audible and visual alarm, emitting a clear audible and visual warning (such as a high-decibel buzzer and flashing warning lights) to alert on-site or nearby personnel. Simultaneously, the receiver's built-in SMS push module calls a preset SMS sending interface to send a mouse-catching notification SMS to a pre-set mobile phone number. The SMS content includes information such as the location of the mouse-catching device and the approximate time of catching, allowing remote management personnel to be promptly informed of the mouse-catching situation, achieving multi-dimensional and rapid-response alarm notifications.

[0039] Insulation Protection Layer: An insulation protection layer is applied to the high-voltage discharge areas of the capacitor bank charging and discharging module (such as electrodes and capacitor output connection points). Insulating materials with good insulation properties, high voltage resistance, and wear resistance (such as silicone insulating coatings, epoxy resin insulating boards, etc.) are selected to isolate the high-voltage live parts from the external environment, preventing accidental electric shock hazards caused by workers touching them, and also preventing unintended discharges or device damage caused by rodents or other organisms coming into contact with the high-voltage area.

[0040] Moisture-proof circuit design: To address the potentially humid environments the device may encounter (such as warehouses during the rainy season in southern China, or near kitchen sinks), key circuit components (such as the wiring terminals of the PLC control module, the signal processing circuits of the photoelectric sensor module, and the RF circuits of the wireless communication module) are encapsulated with sealant. The sealant effectively prevents external moisture intrusion, avoids short circuits in humid environments, ensures stable operation of each module, and enhances the device's adaptability and reliability in complex environments.

[0041] Fault Detection Logic: Fault detection of key components is implemented through PLC programming, covering three main types of faults: photoelectric sensor failure, capacitor bank voltage abnormality, and wireless communication interruption. For photoelectric sensor failures, the PLC program periodically checks the signal status of port X1; if... If no normal high / low level changes are detected within a set time period (e.g., 10 consecutive minutes) (neither a low level when a mouse blocks the path nor a high level after a mouse enters), the photoelectric sensor is deemed faulty. For abnormal capacitor bank voltage, the PLC's analog input module (or an external voltage detection circuit) is used to collect the capacitor bank voltage value in real time. If the voltage value continuously deviates from the set charging voltage range (e.g., if the voltage is continuously lower than 11.5V or higher than 12.5V when the set charging voltage is 12V±0.5V), the capacitor bank voltage is deemed abnormal. For wireless communication interruption faults, the PLC monitors whether a response signal is received from the receiver within a set time (e.g., 5 seconds) after the Y1 port is triggered (this can be achieved through the bidirectional communication function of the wireless communication module or by setting a simple signal feedback verification mechanism in the program). If no response signal is received, the wireless communication is deemed interrupted.

[0042] Fault Alarm and Recording: When any of the above faults is detected, the PLC immediately controls the alarm indicator light to flash (a dedicated fault alarm indicator light can be installed on the device casing; different fault types correspond to different flashing frequencies, such as fast flashing for photoelectric sensor faults and slow flashing for capacitor bank voltage abnormalities). Simultaneously, the fault code is recorded in the PLC's internal register (e.g., code "E01" represents a photoelectric sensor fault, "E02" represents a capacitor bank voltage abnormality, and "E03" represents a wireless communication interruption). Operators can read the fault codes and quickly locate the fault type by connecting to the PLC programming software or the device's simple display interface, facilitating repair and maintenance.

[0043] Example of device workflow (taking mouse trapping in a home kitchen as an example) Deployment and Initialization: Place the real-time mouse monitoring device in a corner of the kitchen, near food storage areas and in areas with high mouse activity. Close the power switch to start the PLC control module. The block triggers the power-on initialization subroutine via the M8002 special relay to initialize the status of each register and output port, and the device enters standby mode. At this time, the photoelectric sensor module continuously emits and receives light to monitor whether a mouse enters the 30cm detection range; the capacitor bank charging and discharging module is in an uncharged standby state; the wireless communication module is in a triggerable state if the communication switch input (X2 port) is high (communication alarm is enabled by default); the safety protection module normally performs its insulation and moisture-proof functions; and the fault diagnosis module begins to periodically check the status of each component.

[0044] Mouse trapping trigger and execution: When a mouse enters the detection range (within 30cm) of the photoelectric sensor along a corner of the wall, blocking the light, the sensor outputs a high-level signal to the X1 port of the PLC. Upon detecting the high level at the X1 port, the PLC program controls the capacitor charging and discharging module to begin... During charging, the internal circuit charges the capacitor bank to a set voltage of 12V. Simultaneously, it continuously monitors the X1 port signal to confirm the mouse remains within the electric shock zone (if the signal remains high for more than 0.5 seconds, to avoid false triggering). Subsequently, the PLC controls the Y0 port to output a high level, triggering the capacitor bank charging / discharging module to discharge instantaneously, delivering a 1.5KV high-voltage electric shock for 2 seconds, stunning the mouse.

[0045] Alarm and Feedback: Simultaneously with the capacitor bank's discharge, the PLC controls the Y1 port to output a high-level signal, triggering the wireless communication module. The wireless communication module sends a mouse-catching alarm message to the indoor receiver in the home at a frequency of 433MHz. Upon receiving the signal, the receiver simultaneously triggers an audible and visual alarm, emitting a continuous audible and visual warning; and sends a text message to the pre-bound mobile phone number of the homeowner, containing information such as "when and where the kitchen mouse trap was triggered."

[0046] Troubleshooting (assuming a photoelectric sensor malfunction): If kitchen fumes, dust, or other contaminants cause pollution to the photoelectric sensor filter, reducing detection accuracy, the PLC fault diagnosis module will detect a prolonged period of no normal signal change at port X1 during periodic checks, indicating a photoelectric sensor malfunction. The system will then control the fault alarm indicator to flash rapidly and record the fault code "E01" in the register. The homeowner can view the fault code through the device's simple display interface and contact a technician to clean or replace the photoelectric sensor to restore the device's normal detection function.

[0047] Through the coordinated operation of the above modules and detailed implementation process, this real-time rodent monitoring device achieves accurate detection, intelligent electric shock control, real-time alarm feedback, reliable safety protection and fault diagnosis, effectively solving many shortcomings of traditional and existing rodent-catching equipment, adapting to rodent-catching needs in multiple scenarios such as homes and warehouses, and improving rodent-catching efficiency and management convenience.
