[0002] Since the cable trench is widely distributed, difficult to observe, long in length, much rain, and poor in environment, it is difficult to achieve the monitoring of each point in the cable at a high cost. When the cable trench is inspected, the method is single, the cover plate needs to be opened, and the maintenance cost is high. Since the cable is densely laid, the real-time monitoring of the cable temperature, fire, water accumulation, and mouse activity in the trench cannot be effectively performed, and the on-duty personnel cannot easily inspect and find the situation in the cable trench, which is close to a blind area of management and control. Once a fault occurs in the cable trench, it is usually difficult to handle and time-consuming, which seriously threatens and affects the safe operation of electrical equipment.

Detailed Implementation

[0038] The application will be further described below in conjunction with the drawings and embodiments.

[0039] It should be noted that the cable trench is prone to fire, rat infestation and other situations, so we need to monitor the situation in the cable trench to master it, so as to eliminate potential dangers and perceive and stop in time when the danger occurs. However, there are many difficulties in cable trench monitoring: 1. The cable trench is long along the way, and the cost of setting up a full-range monitoring camera along the way is too high; 2. The cable trench is usually set in remote areas, and manual monitoring costs are high, and problems cannot be found in time; 3. The environment in the cable trench is complex and harsh, and industrial monitoring robots are difficult to apply to this situation, and the cost is high.

[0040] Therefore, as shown in Figures 1 to 7 The embodiment provides a composite light intelligent monitoring system suitable for narrow and harsh environment of cable trench, which is installed at the cable trench and comprises a composite light monitoring mobile 1, a tubular track 2, a traction wire bundle 3 and a mobile traction device 4.

[0041] Specifically, the tubular track 2 is laid along the cable trench along the way and fixedly installed on the upper part of the side wall of the cable trench; a cable trench monitoring port 16 is also penetrated and formed on the pipe wall of the tubular track 2, and a C-shaped structure tubular track is formed; the cable is laid at the bottom of the cable trench, and the cable trench monitoring port 16 is arranged towards the cable.

[0042] Specifically, the composite light monitoring mobile 1 is installed in the tubular track 2 and comprises a mobile shell 11 and a composite light monitoring device installed in the mobile shell 11; the mobile shell 11 comprises a columnar cavity, a cavity sealing cover 13 and a cable monitoring port 12, the cable monitoring port 12 is arranged in the middle part of the side wall of the columnar cavity and is sealed by a transparent baffle; the cavity sealing cover 13 is threadedly installed at both ends of the columnar cavity, a wire bundle hole is formed in the middle part of the cavity sealing cover 13, one end of the traction wire bundle 3 is fixed in the wire bundle hole through a bunching sealing ring 14, and the other end is connected with the mobile traction device 4.

[0043] Specifically, the mobile traction device 4 comprises an A-end active traction machine and a B-end active traction machine and is respectively installed at the two ends of the cable trench; the other end of the traction wire bundle 3 is connected with the mobile traction device 4 on the same side.

[0044] It should be noted that, as Figure 1As shown, the composite light monitoring device proposed in the embodiment adopts a composite light monitoring mover 1 to monitor the whole way along the cable trench. Since the composite light monitoring mover 1 can realize the movement and positioning of the mover under the cooperation of the traction wire bundle 3 and the mover traction device 4, the accurate monitoring of each area in the cable trench can be realized. Since the composite light monitoring mover 1 is installed in the tubular track 2, and the composite light monitoring device is wrapped and protected by the mover shell 11, the device can adapt to the harsh environment in the cable trench and ensure the waterproof, sandproof and dustproof of the device.

[0045] As a further solution, the mover shell 11 is further provided with a limiting buckle frame 15 at the edge of the cable monitoring port 12. The mover shell 11 is installed in the tubular track 2, the limiting buckle frame 15 is buckled at the cable trench monitoring port 16, and the orientation of the mover shell 11 is fixed.

[0046] It should be noted that: Figure 2 As shown, Figure 3 As shown, since the mover shell 11 is in a cylindrical shape, it is easy to rotate and deviate during the dragging movement, which causes the cable monitoring port 12 to fail to align with the cable. Therefore, the embodiment sets the limiting buckle frame 15 at the edge of the cable monitoring port 12 to ensure that the mover shell 11 does not deviate.

[0047] As a further solution, the traction wire bundle 3 includes a power traction wire bundle and a communication traction wire bundle, and is connected with an A-end active traction machine or a B-end active traction machine.

[0048] Specifically, the power traction wire bundle includes an outer traction wire bundle and an inner power wire bundle; the outer traction wire bundle wraps the inner power wire bundle; the communication traction wire bundle includes an outer traction wire bundle and an inner communication wire bundle; the outer traction wire bundle wraps the inner communication wire bundle.

[0049] It should be noted that: in order to realize the whole monitoring, it is necessary to provide a communication channel and a power supply line. However, the environment along the cable trench is complex and buried underground, so it is difficult to transmit video data through a wireless communication mode. Therefore, the embodiment combines the power line and the data line into the traction wire bundle 3 to realize the stable communication and power supply of the device.

[0050] As a further solution, the composite light monitoring device includes a visible light shooting lens, an infrared light shooting lens, a light supplement lamp, a communication module, a voltage stabilizing module and a shooting control module.

[0051] Specifically, the visible light shooting lens, the infrared light shooting lens, the light supplement lamp, the communication module and the voltage stabilizing module are electrically connected with the shooting control module, and the shooting control module is set through an MCU chip; the voltage stabilizing module is further electrically connected with one end of the inner layer power line bundle; the communication module is further electrically connected with one end of the inner layer communication line bundle; the visible light shooting lens, the infrared light shooting lens and the light supplement lamp are installed at the cable trench monitoring port 16.

[0052] It should be noted that the visible light shooting lens can monitor the environment in the cable trench, such as rodent disasters, the infrared light shooting lens can monitor fire and the like, and the light supplement lamp can provide a shooting light source in a dark environment. The communication module, the voltage stabilizing module and the shooting control module are all existing chip modules.

[0053] As a further solution, the A-end active traction machine and the B-end active traction machine adopt the same traction machine, which includes a traction motor, a wire spool, a wire bundle storage box, a traction control module and a power module. The traction motor and the power module are electrically connected with the traction control module, the traction motor is connected with the wire spool shaft, the wire spool is installed in the wire bundle storage box, one end of the traction wire bundle 3 is fixed on the wire spool and is stored in the storage box in a spiral spool structure; the power module is electrically connected with the other end of the inner layer power line bundle.

[0054] It should be noted that existing mover moving technologies mainly include a load plate moving type, a shaft driving type and a wire bundle traction type. The load plate moving type is self-driven through a micro motor on a load plate, and realizes remote control and power supply by combining NCT cableless power supply and cableless communication technology. However, the technology device is complex, suitable for automatic factory and the like, and not suitable for cable trench and the like with poor environment. The shaft driving type has low cost, sufficient driving force and simple device, but due to the existence of curved terrain along the way and long driving distance, the shaft driving cannot be deployed in such an environment, such as shown in Figure 6 Therefore, the wire bundle traction type is selected to provide kinetic energy for the composite light monitoring mover 1.

[0055] As a further solution, a synchronous traction module is further arranged between the A-end active traction machine and the B-end active traction machine, and the synchronous traction module includes a traction controller, a traction driver, a motor synchronization circuit and an indication and switch unit, as shown in Figure 8 .

[0056] Specifically, the traction controller is an MCU controller, including a plurality of I / O ports; the traction driver is a drive control chip of ULN2003A type, including input port a1, input port a2, input port a3, input port a4, input port a5, input port a6, input port a7, input port a8, output port b1, output port b2, output port b3, output port b4, output port b5, output port b6, output port b7 and output port b8; the indication and switch unit includes relay 1, relay 2, a buzzer, indicator lamp 1 and indicator lamp 2; the motor synchronization circuit includes two reverse branches with the same structure, and each reverse branch includes a shunt and an inverter; the shunt includes an input end and two output ends, one of which is used as a same-phase output end, and the other output end is connected with the inverter and used as an opposite-phase output end.

[0057] In the embodiment, input port a1, input port a2, input port a3, input port a4, input port a5, input port a6 and input port a7 are connected with the ground through 4K ohm resistors respectively, and are connected with the corresponding I / O ports respectively; input port a8 is directly connected with the ground; input port a1 and input port a2 are connected with relay 1 and relay 2 respectively, and the other ends of relay 1 and relay 2 are connected with +12V direct current; output port b3 and output port b4 are used as control output ports, and are connected with the reverse branches respectively, and the same-phase output ends of the two reverse branches are connected with the traction control module of any A active traction machine or B active traction machine; the opposite-phase output ends of the two reverse branches are connected with the other traction control module, and the two traction control modules are also connected with +12V direct current respectively; output port b5, output port b6 and output port b7 are connected with the buzzer, indicator lamp 1 and indicator lamp 2 respectively, and are connected with +12V direct current; output port b8 is connected with +12V direct current, and a capacitor C is arranged between output port b8 and input port a8.

[0058] It should be noted that, as shown in FIG. 1, the traction control module is connected with the traction driver through the I / O ports of the MCU controller, and the traction driver is connected with the motor synchronization circuit through the input ports a1-a8. Figure 7As shown, since the "double-end wire harness traction" scheme is adopted, the traction motors at both ends need to rotate synchronously and reversely. The reverse synchronous rotation can be achieved by an integrated CAN bus stepper motor driver PMC007. PMCO07CxSxP is a micro-integrated stepper motor subdivision controller that can be directly installed on the rear cover of 42 / 57 / 86 series stepper motors. This series of controllers provides CAN bus control and different current profile selection. Using PMC007CxSxP stepper motor controller can easily realize up to 120 nodes of industrial control network system, and can realize encoder-based closed-loop control according to user requirements. PMC007CxSxP adopts the industrial standard CANOPEN DS301 control protocol, which greatly simplifies the complexity of the upper control system, and maximizes the flexibility of control, suitable for various high-precision, wide-range industrial applications. However, the integrated CAN bus stepper motor driver has high cost, and the system only has two controlled units, so the embodiment proposes a low-cost synchronous driving circuit based on ULN2003A driving control chip, which takes into account the practicality and cost advantage.

[0059] As a further solution, a monitoring server and an intelligent monitoring system are further provided, the monitoring server is electrically connected with the other end of the inner communication wire harness, and the monitoring server is electrically connected with the traction control module.

[0060] The intelligent monitoring system comprises a monitoring control system and a monitoring display system; the monitoring control system comprises a control console and a control keyboard, the control keyboard is electrically connected with the control console, and the control console is electrically connected with the monitoring server; the monitoring display system comprises a display driver and a display screen, the display screen is electrically connected with the display driver, and the display driver is electrically connected with the monitoring server.

[0061] It should be noted that: setting a remote monitoring server can realize data distribution and realize more functions. Such as remote monitoring, remote control, remote fault analysis, etc.

[0062] As a further solution, an image recognition system is further provided, the image recognition system is obtained by training a machine learning model through a training data set; the training data set is obtained by collecting a fusion image data RGB_T of the cable trench anomaly and performing data augmentation processing, the training data set is divided into a training set and a test set, the training set is used for image recognition training of the machine learning model, the test set is used for testing the machine learning model, and an identification accuracy is obtained, when the identification accuracy reaches an identification precision, the training of the machine learning model is stopped, and the machine learning model is output as an image recognition system.

[0063] As a further solution, a mover positioning module is also provided; the traction motor is a stepper motor, and the traction control module is a programmable stepper motor control drive module including a drive register; the mover positioning module is electrically connected to the drive register and forwards the electrical signals in the drive register to the monitoring server. The monitoring and positioning module performs positioning through the following steps:

[0064] S1 acquires the initial position (L1, L2) of the composite light beam monitoring mover, where L1 is the distance from the composite light beam monitoring mover to the active traction machine at end A, and L2 is the distance from the composite light beam monitoring mover to the active traction machine at end B.

[0065] S2 obtains the current number of rotations D, deflection angle θ, and steering direction i of the active traction machine at end A or end B;

[0066] S3 obtains the diameter R of the coil on the spool;

[0067] S4 calculates the position offset ΔL, ΔL = (-1) i πR(D+θ / 360), where i=0 indicates the direction of rotation to end A, and i=1 indicates the direction of rotation to end B;

[0068] S5 corrects the current position of the moving carrier (L1+ΔL, L2-ΔL) and completes the positioning.

[0069] It should be noted that traditional solutions based on positioning sensors are used for locating fault locations or cameras. However, these sensors are not very accurate in scenarios like cable trenches, are easily damaged, and are costly. Therefore, this embodiment uses a stepper motor and reads data such as the number of rotations and the wheelbase from the registers in the programmable stepper motor control drive module to calculate the traction length. Since the cable trench is linear, the current location can be determined based on the traction length.

[0070] It should be noted that the image recognition system can identify visible light smoke, fire, electric arc, small animals, and flooding data of target cables, and realize corresponding early warning and prediction functions. The system also has back-end management functions such as data storage and image and video browsing.

[0071] As a further solution, the composite light monitoring mover 1 is also provided with graphite collars at both ends; the graphite collar includes a graphite ring 131 and a rubber ring 132, the graphite ring 131 is nested in the outer layer of the rubber ring 132, and a collar mounting groove 17 is opened on the outer wall of the columnar cavity, and the rubber ring 132 is nested in the collar mounting groove.

[0072] It should be noted that: such as Figure 4 and Figure 5As shown, since the composite light ray monitoring mobile 1 needs to move in the tubular track 2, graphite collars are used to solve the problem of frictional damage to the pipe wall and the mobile shell 11. The graphite ring 131 of the outer layer of the graphite collar can well prevent frictional damage to the device, the rubber ring 132 can slow down the shock caused by movement, and the collar installation groove 17 can fix the graphite collar therein and facilitate replacement.

[0073] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
