DETAILED DESCRIPTION

[0021] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0022] The first implementation method: Figure 1-6 It is shown that a multifunctional cable with risk perception and early warning function includes multiple cables, and a drag chain protective cover is connected between the multiple cables. The cable includes a wire core 1, and the outer end of the wire core 1 is connected to an inner protective layer 2. The outer end of the inner protective layer 2 is covered with a heat-conducting mesh 3, and the heat-conducting mesh 3 is made of woven heat-conducting fibers. The mesh number of the heat-conducting mesh 3 includes 40 meshes to 100 meshes; The heat-conducting net 3 is covered with an outer insulating layer 4, and a plurality of annular grooves are formed on the outer insulating layer 4; a temperature-changing ring is clamped in the annular groove, and the temperature-changing ring is made of a thermochromic material, and the temperature change temperature of the temperature-changing ring is greater than 60 degrees Celsius; The drag chain protective cover includes a pair of end covers 5, and a plurality of drag chain units 6 are connected between the pair of end covers 5 and are rotatably connected in sequence head to tail. The drag chain unit 6 includes a main housing 61, and a shaft seat and a shaft frame are respectively installed at the front and rear ends of the main housing 61. Two adjacent main housings 61 are rotatably connected through the shaft seat and the shaft frame; A wire fixing plate 62 is installed in the main shell 61, and a plurality of wire threading holes matching the cables are opened on the wire fixing plate 62; a temperature variable ring is clamped in the annular groove, and the temperature variable ring is made of thermochromic material. When the cable is installed in the drag chain protective cover, the temperature variable ring is not installed in the annular groove matching the position of the wire fixing plate 62; a plurality of air holes can be arranged on the temperature variable ring to assist the cable in heat dissipation.

[0023] The cable exposed between two adjacent drag chain units 6 has its annular groove protected by a temperature variable ring to prevent external impurities from contaminating the heat conductive network 3. When the cable is overheated, the temperature variable ring changes color, making it easy to visually observe the overheated part of the cable and facilitate visual warning.

[0024] Both upper and lower ends of the main housing 61 are provided with mounting grooves, a sliding hole extending to the mounting groove is provided in the threading hole, a fixed wire post 9 is rotatably connected in the sliding hole, a docking groove matching the temperature sensing ring 72 is provided on the outer side of the top of the fixed wire post 9, a hexagonal groove is provided in the middle of the top of the fixed wire post 9, a movable post 91 is threadedly connected to the bottom end of the fixed wire post 9, and a fixed wire arc plate 92 is installed at one end of the movable post 91 located in the threading hole; the hexagonal groove is used to facilitate the use of tools to rotate the fixed wire post 9; The wire fixing column 9 and the movable column 91 are both made of heat-conducting material, the wire fixing arc plate 92 is made of elastic heat-conducting material, and the width of the wire fixing arc plate 92 matches the width of the annular groove; Optionally, a fixed thorn is fixedly connected to the fixed arc plate 92, the length of the fixed thorn matches the thickness of the outer insulating layer 4, and the fixed thorn is made of a heat-conducting material; the fixed thorn pierces the outer insulating layer 4 and contacts the heat-conducting net. When the cable is replaced, if the installation error causes the annular groove to not match the fixed arc plate 92, or the cable without the annular groove is installed, the fixed thorn can be pierced into the outer insulating layer 4 to monitor the temperature of the heat-conducting net. At the same time, the heat-conducting net 3 is in a mesh shape, and its structure is not easily destroyed when the fixed thorn pierces, so it is easy to ensure the integrity of the inside of the cable; An early warning unit 7 is carded in the installation groove, and the early warning unit 7 includes a monitor body 71, and a plurality of temperature sensing rings 72 matching the docking grooves are fixedly connected to the lower end of the monitor body 71; a data transmission socket 8 matching the early warning unit 7 is installed on the main shell 61, and an elastic data line is connected between two adjacent data transmission sockets 8; a line hub connector connected to a plurality of cables is installed on the two end covers 5, and a data transmission interface matching the elastic data line is provided on the wiring plug.

[0025] Optionally, symmetrically arranged laser transmitters and laser receivers are respectively installed at the front and rear ends of the early warning unit 7. For the straight section of the cable, the two adjacent early warning units 7 can monitor the straightness of the cable through the laser transmitter and the laser receiver. When the cable remains flat, the laser emitted by the laser transmitter of one early warning unit 7 is received by the laser receiver of the other early warning unit 7. When the straight section of the cable is deformed by an external force, the drag chain unit 6 is deformed or rotated accordingly. At this time, the laser receivers of the two adjacent early warning units 7 do not match the laser receiver. The laser receiver and the laser receiver are periodically turned on to assist in monitoring the situation of the cable area where the early warning unit 7 is not provided with the external force. After installation, the early warning unit 7 is connected in parallel with the data transmission socket 8, and two adjacent data transmission sockets 8 are connected in series through elastic data lines. The early warning unit 7 and the data transmission socket 8 are respectively installed with wiring plugs and wiring plugs. A temperature sensor matching the temperature sensing ring 72 is installed in the early warning unit 7. A pressure sensing film is laid at the lower end of the early warning unit 7, and a buffer protective layer is provided on the surface of the early warning unit 7.

[0026] When in use, after the drag chain protective cover is laid and fixed, the warning unit 7 is selected and installed in the installation slot at a suitable position. At this time, the warning unit 7 is connected to the data transmission socket 8 through the wiring plug and the wiring plug, and the temperature sensing ring 72 on the warning unit 7 is connected to the top of the fixed wire column 9; When the early warning unit 7 is working, the external force condition of the early warning unit 7 installation area is monitored through the pressure sensing membrane, and the temperature of the temperature sensing ring 72 is monitored through the temperature sensor to realize the cable temperature monitoring; at the same time, in this scheme, a heat conducting net 3 is arranged in the cable, and a plurality of annular grooves that allow the heat conducting net 3 to be exposed are arranged on the outer insulating layer 4. On the one hand, the setting of the annular groove facilitates the fixing of the cable by the wire fixing arc plate 92, and on the other hand, it facilitates the wire fixing arc plate 92 to transfer the heat of the heat conducting net 3 to the temperature sensing ring 72 through the wire fixing column 9 and the movable column 91, so that the temperature sensor in the early warning unit 7 can monitor the heating temperature of the wire core 1 more accurately, so as to facilitate timely warning when the wire core 1 is overheated.

[0027] Second implementation method: Figure 7 It is shown that the present solution also includes a risk warning system, which includes a monitoring terminal connected to the data transmission interface signal, a processor is provided in the monitoring terminal, and a monitoring module, an early warning module, a data processing module and a data storage module are connected to the processor; Monitoring terminal: It is the core of the risk warning system. It integrates the processor, monitoring module, warning module, data processing module and data storage module. The monitoring terminal is connected to the warning unit 7 and data transmission socket 8 of the cable through the data transmission interface to realize real-time data exchange and processing. The monitoring terminal usually has a user interface to facilitate operators to view real-time data, historical records and system status.

[0028] The monitoring module collects the monitoring data of the early warning unit 7 in real time. The monitoring data includes temperature data and pressure data. The temperature data is obtained by monitoring the temperature of the temperature-sensitive ring 72 through the temperature sensor. These temperature-sensitive rings are in direct contact with the heat-conducting net 3 of the cable through the fixed wire column 9, the movable column 91 and the fixed wire arc plate 92, and can more accurately reflect the heating condition of the wire core 1; the pressure data is obtained through the pressure sensing membrane; The data processing module is responsible for processing the monitoring data collected from the monitoring module and judging whether there are risk situations according to the set parameters. Risk situations include deformation, overheating and impact. When judging overheating risk, process temperature data, analyze temperature change trends, and predict potential overheating risks; The deformation risk is judged based on whether the pressure data exceeds the set threshold a and whether the laser receiver receives the laser; When judging the impact risk, the judgment is made based on whether the pressure data exceeds the set threshold b; After the data processing module processes the monitoring data, it passes it to the data storage module and sends the judgment results to the early warning module. In addition, the data processing module is also responsible for optimizing the performance of the monitoring terminal to ensure the accuracy of the data and the response speed of the system.

[0029] The early warning module receives the judgment results from the data processing module. If it is judged that there is a risk situation, the early warning module will trigger the preset alarm measures, such as reminding relevant technical personnel or taking automatic measures. The automatic measures include: reducing the load or cutting off the power supply to prevent cable failure caused by risk situations.

[0030] Data storage module: used to store all operating data during the operation of the cable, including temperature records, warning events and operation logs. The data storage module facilitates the later analysis of the cable's operating status, evaluates the effectiveness of the risk warning system, and provides data support for future maintenance and upgrades.

[0031] Through the collaborative work of various modules, the risk warning system can effectively monitor the operating status of the cable, timely detect and warn of potential risks, thereby ensuring the safe and stable operation of the cable.

[0032] The drag chain protective cover of this solution not only protects the cable, but also realizes risk monitoring of the cable. The flexibly installable warning unit 7 enhances the perception of the cable operation status, and is easy to adapt to the risk monitoring and warning needs of the cable installed in different usage environments. At the same time, the design of the data transmission socket and the elastic data cable on the drag chain protective cover ensures the stability and reliability of the monitoring data transmission, and ensures the timely discovery and warning of risk situations.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
