Description

Technical Field

[0001] This application relates to the field of surveillance technology, and in particular to an intelligent surveillance and inspection system. Background Technology

[0002] Currently, there are two main technical solutions for achieving seamless indoor surveillance coverage:

[0003] Fixed camera array solution: consists of cameras fixedly installed on the wall, a hard disk recorder (responsible for storing camera footage) in a control cabinet, an industrial control computer, a monitor (responsible for displaying camera footage in real time), and a switch. Because the cameras are fixedly installed, even if the cameras can rotate 360 ​​degrees, there are still blind spots and areas that cannot be monitored. If it is required that there are as many blind spots as possible indoors, the number of cameras needs to be increased, which in turn increases the number of hard disk recorder channels, hard disk size, and power supply cabling. Expanding the monitoring range by increasing the number of cameras leads to a significant increase in hardware costs (hard disk recorders, switches) and cabling complexity.

[0004] Mobile inspection device solutions: For example, patent document CN223049803U provides a workshop equipment operation monitoring device with an inspection structure. However, this solution relies on the mechanical linkage of a hydraulic telescopic rod and a gear rack for assembly and disassembly, which poses risks of jamming and oil leakage in dusty and humid environments, resulting in high maintenance frequency. For long-distance wall monitoring, existing solutions typically require the deployment of multiple cameras or guide rails to avoid horizontal blind spots. While this approach expands the monitoring range to some extent, it also leads to high hardware costs, failing to fundamentally reduce user operating costs. Utility Model Content

[0005] This application provides an intelligent monitoring and patrol system, which aims to solve the problem of difficulty in fundamentally reducing user costs when there are many blind spots or long-distance monitoring needs.

[0006] Firstly, an intelligent monitoring and patrol system is provided, characterized by comprising:

[0007] A fixed monitoring unit, including at least one camera fixedly mounted on a wall;

[0012] The PLC controller is connected to each servo driver via a 485 bus. Its input terminal receives the motor origin limit signal and the driver fault signal; its output terminal receives the driver power supply control signal.

[0013] Optionally, in the above scheme, the belt drive mechanism includes a driving wheel and a driven wheel located at both ends of the sliding electric guide rail, and the motor output shaft is connected to the driving wheel.

[0014] Optionally, in the above scheme, the sliding electric guide rail is provided with mechanical positive / reverse limit switches at both ends and directly connected to the servo driver, and the guide rail is provided with an origin limit switch in the middle and connected to the PLC controller.

[0015] Optionally, in the above scheme, the main control cabinet is equipped with:

[0016] The D-type tripping leakage protection circuit breaker has its output connected to a servo driver via a filter.

[0017] All motors have their grounding terminals connected to both the mains ground wire and the building ground wire.

[0018] Optionally, in the above scheme, the mobile camera transmits monitoring data via WIFI, and the fixed camera transmits data via a wired network.

[0019] Optionally, in the above scheme, each servo drive's control box is equipped with an emergency stop button, a reset button, and a self-test button, wherein the emergency stop button directly cuts off the power supply to the corresponding drive.

[0020] Optionally, in the above scheme, the PLC controller includes a programmable memory containing control instructions.

[0021] The input port of the PLC controller is connected to the origin limit switch via a hard wire, and the output port is connected to the servo driver and the moving camera via a hard wire or a 485 bus.

[0022] The system is configured as follows:

[0023] When the physical trigger signal of the origin limit switch is input to the PLC controller, it outputs an electrical pulse command to the servo driver to stop the motor at the origin position;

[0024] The servo driver controls the motor to move to a preset physical position on the sliding electric guide rail;

[0025] At each preset point, a level signal is output to the mobile camera via the IO interface to trigger the mobile camera to perform a 360° scan.

[0026] The video stream from the mobile camera is transmitted to the host computer via the physical circuitry of the communication module, which is a WIFI module installed inside the mobile camera housing.

[0027] Optionally, in the above scheme, the power supply copper rail of the sliding power rail forms a sliding electrical connection with the power-taking slider of the camera; the power-taking slider is rigidly connected to the moving camera by an insulating bracket, and an elastic clamping element is provided between the slider and the copper rail to maintain continuous electrical contact during the sliding process.

[0028] Optionally, in the above scheme, the mobile camera is protected by moving via a cable chain, with one end of the cable chain fixed to the end bracket of the sliding power rail and the other end fixed to the base of the mobile camera.

[0029] Compared with the prior art, this application has at least the following beneficial effects:

[0030] Based on further analysis and research into existing technical problems, this application recognizes the difficulty in fundamentally reducing user costs when there are many blind spots or long-distance monitoring requirements. This application addresses this issue by integrating fixed and sliding monitoring units. Fixed cameras handle basic monitoring, while the sliding monitoring unit, through a sliding power rail, a moving camera, a motor, and a belt drive mechanism, works collaboratively to achieve long-distance monitoring by sliding horizontally along the wall. Simultaneously, a control module consisting of a PLC controller and servo driver, and a power supply module consisting of a main control cabinet and a switching power supply, ensure stable and efficient system operation. This effectively reduces the number of cameras, lowering hardware costs and wiring complexity. The long-distance monitoring capability of the sliding power rail avoids the high costs of deploying multiple devices, while the belt drive mechanism, compared to complex mechanical linkages, offers greater stability, adaptability to various environments, and significantly reduced maintenance costs.

[0031] This application is compatible with and integrates existing fixed cameras and other monitoring facilities in old factories, incorporating them into a unified monitoring and management system. This eliminates the need for complete removal of existing equipment, reducing the number of devices that need to be replaced or rearranged, thus significantly lowering renovation costs. Furthermore, this application can effectively integrate with existing monitoring systems in old factories, achieving optimized resource allocation and efficient utilization. It avoids large-scale dismantling and reconstruction of the original monitoring system, effectively saving renovation costs and improving the overall cost-effectiveness and practicality of the system.

[0033] Figure 2 This is a power supply schematic diagram of an intelligent monitoring and patrol system provided in one embodiment of this application. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] In the description of this application, unless otherwise stated, the terms "including", "comprising", "having", etc., also mean "not limited to" (certain units, components, materials, steps, etc.).

[0036] This application aims to provide an intelligent monitoring and inspection system that retains wall-mounted cameras for monitoring in large-angle indoor areas with few obstructions. The remaining cameras are equipped with sliding electric rails. The cameras on the electric rails are controlled by a mechanical structure consisting of an end motor and a belt, with the motor's forward and reverse rotation controlling the camera's forward and reverse movement. The cameras are not limited to a single location; thus, installing one camera at a certain height on one wall allows for left and right-side scanning, making it suitable for warehouses and multi-shelf environments.

[0037] In one embodiment, an intelligent monitoring and patrol system is provided, comprising:

[0038] A fixed monitoring unit, including at least one camera fixedly mounted on a wall;

[0039] The sliding monitoring unit includes a sliding electric rail, a mobile camera that can move along the sliding electric rail, a motor that drives the mobile camera to slide, and a belt drive mechanism.

[0040] The control module includes a PLC controller and a servo driver connected to the motor;

[0041] The power supply module includes a main control cabinet that supplies power to the motor and a switching power supply that supplies power to the camera;

[0042] The sliding electric guide rail is horizontally arranged along the wall, and the motor drives the mobile camera to reciprocate along the sliding electric guide rail through a belt transmission mechanism.

[0043] The PLC controller is connected to each servo driver via a 485 bus. Its input terminal receives the motor origin limit signal and the driver fault signal; its output terminal receives the driver power supply control signal.

[0044] This utility model provides a new technical solution: an intelligent monitoring and inspection system. The hardware includes a camera, hard disk recorder, controller, motor, belt, sliding power rail, limit switches (mechanical and non-mechanical), voltmeter, ammeter, filter, and multiple control cabinets (indoor area requires WIFI coverage). The switching power supply converts AC mains power to 12V to power the camera. Mobile cameras upload monitoring footage via WIFI, while fixed cameras upload footage via network cable or fiber optic cable. A small control cabinet (main control cabinet) is located near the motor to house the servo driver. The power and encoder cables between the driver and motor are minimized to reduce maintenance difficulty.

[0045] This application reduces the number of hardware devices, eliminating the limitation of fixed-installation cameras. It allows for multi-angle and multi-position viewing, and monitors indoor situations by controlling the simultaneous movement of multiple cameras on multiple walls. The system links the controller and motor-mounted cameras, and the cameras can be configured with facial recognition and specific shape definitions. The efficiency of manually observing and locking onto specific objects is limited, and the system of this application can improve efficiency to a certain extent.

[0046] In one embodiment, the belt drive mechanism includes a driving wheel and a driven wheel located at both ends of a sliding electric guide rail, with the motor output shaft connected to the driving wheel.

[0047] In one embodiment, the sliding electric guide rail is equipped with mechanical positive / negative limit switches at both ends and directly connected to a servo driver, and an origin limit switch is provided in the middle of the guide rail and connected to a PLC controller.

[0048] In this embodiment, the positive and negative limit switches are directly connected to the driver. These limits are not controlled by the controller. The origin limit switch is directly connected to the controller to prepare for the subsequent encoder calibration or zeroing.

[0049] In one embodiment, the main control cabinet is equipped with:

[0050] The D-type tripping leakage protection circuit breaker has its output connected to a servo driver via a filter.

[0051] All motors have their grounding terminals connected to both the mains ground wire and the building ground wire.

[0052] In this embodiment, a power supply control cabinet (main control cabinet) is required indoors. The circuit breaker providing power to the motor is a D-type trip circuit breaker with leakage protection. The sliding power guide rail is mounted on the wall, which raises safety concerns, preventing leakage current. Furthermore, the grounding terminal of each motor needs to be connected to both the mains ground wire and the building ground for double protection. A filter is installed between the lower terminal of the circuit breaker and the upper terminals of multiple drivers to filter the mains power and reduce the interference of mains power fluctuations on the driver control circuitry.

[0053] In one embodiment, the mobile camera transmits monitoring data via Wi-Fi, while the fixed camera transmits data via a wired network.

[0054] In one embodiment, each servo drive's control box is equipped with an emergency stop button, a reset button, and a self-test button, wherein the emergency stop button directly cuts off the power supply to the corresponding drive.

[0055] In this embodiment, each small control box contains not only a driver, but also emergency stop, reset, self-test, start, and stop buttons on the cabinet door. To prevent the remote controller from issuing commands that could cause safety issues during maintenance, the emergency stop button on the corresponding control box can be pressed during maintenance. After maintenance is completed, the maintenance personnel can press the reset button to cancel the driver fault error, and then press the self-test function. The camera will run through the normal troubleshooting process to facilitate the maintenance personnel to check whether the problem has been completely resolved.

[0056] In one embodiment, the PLC controller includes a programmable memory containing control instructions.

[0057] The input port of the PLC controller is connected to the origin limit switch via a hard wire, and the output port is connected to the servo driver and the moving camera via a hard wire or a 485 bus.

[0058] The system is configured as follows:

[0059] When the physical trigger signal of the origin limit switch is input to the PLC controller, it outputs an electrical pulse command to the servo driver to stop the motor at the origin position;

[0060] The servo driver controls the motor to move to a preset physical position on the sliding electric guide rail;

[0061] At each preset point, a level signal is output to the mobile camera via the IO interface to trigger the mobile camera to perform a 360° scan.

[0062] The video stream from the mobile camera is transmitted to the host computer via the physical circuitry of the communication module, which is a WIFI module installed inside the mobile camera housing.

[0063] In this embodiment, the following signals are connected to the input terminal of the PLC controller: origin signal of each motor, driver fault signal, driver power supply feedback signal, and camera power supply feedback signal;

[0064] Output signals: driver power supply signal, camera power supply signal;

[0065] 485 output signals: Driver 1a, Driver 2a, Driver 3a, Driver 4a.

[0066] After the hardware wiring is completed, the PLC controller includes a programmable memory containing control instructions. This is achieved through the connection described in this embodiment: by checking the power supply feedback signals from the driver and sliding electric rail; the controller reads that each driver is operating normally and there are no fault alarms; first, the motor returns to its origin, then moves to the set point from the origin, stops in place, and the camera rotates 360 degrees to check for any abnormalities on site. After the check, the absence of abnormalities or any abnormal items are displayed on the host computer for the operator to view. After checking the current position, the camera moves to the next position, and the cycle repeats; after the cycle ends, it returns to its origin, waiting for the next inspection.

[0067] During the operation and use of automated equipment, there will be maintenance needs, or there will be a need for equipment to check whether the movement of the cameras in the monitored room is normal. This can be done by using cameras that are fixedly installed indoors.

[0068] In one embodiment, the power supply copper rail of the sliding power rail forms a sliding electrical connection with the power-taking slider of the camera; the power-taking slider is rigidly connected to the moving camera by an insulating bracket, and an elastic clamping member is provided between the slider and the copper rail to maintain continuous electrical contact during the sliding process.

[0069] In one embodiment, the mobile camera is protected by a drag chain, with one end of the drag chain fixed to the end bracket of the sliding power rail and the other end fixed to the base of the mobile camera.

[0070] The above embodiments can achieve comprehensive coverage of the monitoring area, ensuring no blind spots; reduce labor costs and improve monitoring efficiency.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
