[0018] Specifically, the wire rope 1 to be monitored can be a high-strength tensioned wire rope.

[0019] The hydraulic tension distance unit 10 includes: a hydraulic tension distance gauge and a data transmission module; wherein, the hydraulic tension distance gauge is connected to the steel wire rope 1 to be monitored, and is used to apply an external force to the steel wire rope 1 to be monitored and collect the loosening tension value on the steel wire rope 1 to be monitored and the displacement data caused thereby; the input end of the data transmission module is connected to the hydraulic tension distance gauge, and the output end of the data transmission component is connected to the floating induction unit 20, and is used to send the loosening tension value and the displacement data caused thereby to the floating induction unit 20.

[0020] In this embodiment, the floating induction unit 20 includes: a positive floating capture component and a negative floating capture component; wherein, both the positive floating capture component and the negative floating capture component are connected to the intelligent control unit 30, and are used to send detection results to the intelligent control unit 30 respectively.

[0021] Specifically, the positive floating capture component captures positive data exceeding the set value, and the negative floating capture component captures negative data exceeding the set value. The preset range set in the floating induction unit 20 is +5mm to -5mm. The positive floating capture component and the negative floating capture component start to capture whether the data sent by the hydraulic tension distance unit 10 is within the specified value range (+5mm to -5mm).

[0022] In this embodiment, the sequence coding unit 40 further includes: a sequence coding monitoring module and a sequence coding coordination module; wherein, the sequence coding monitoring module is connected to the sequence coding transfer module, and is used to monitor the sequence coding status of each device in real time. When it is detected that the two unique sequence codes of the device do not change at a fixed time, an instruction is sent to the sequence coding transfer module; the sequence coding coordination module is connected to the sequence coding monitoring module, and is used to receive a notification from the sequence coding monitoring module when a sequence coding system error is detected by the sequence coding monitoring module and execute necessary recovery measures to ensure the normal operation of the system.

[0023] Specifically, each steel wire rope monitoring and warning device has two unique sequence codes, and they change in real time. For example, 1A and 1B are two unique sequence codes, and they change at fixed intervals between 1A and 1B. The function of real-time change: in case the device cannot work properly due to other reasons, the real-time change can timely detect the problem device. That is, when a problem occurs, the device can be found and processed in time.

[0024] Refer to Figure 2 and Figure 3, in actual use, a wire rope monitoring and warning device is connected to each wire rope 1 to be monitored through a U-shaped clamp. When a wire rope becomes loose, the intelligent control unit 30 obtains the coding information of the corresponding warning device from the sequence coding unit 40, so as to clearly locate which wire rope has become loose. More specifically, the U-shaped clamp 3 and the wire rope monitoring and warning device can be fixed together through bolts 2.

[0025] In this embodiment, it may further include: an information transmission unit 60; wherein, the information transmission unit is connected to the intelligent control unit 30, and is used to receive the instruction information of the intelligent control unit 30 and forward the instruction information to the remote end, so that remote personnel can arrange professional personnel to arrive at the scene for maintenance in a timely manner based on the received information.

[0026] In this embodiment, it further includes: a housing; wherein, the floating induction unit 20, the intelligent control unit 30, the sequence coding unit 40 and the warning unit 50 are all placed on the housing and connected to the inside of the housing; the hydraulic tensioning unit 10 is placed inside the housing, and the force application part of the hydraulic tensioning unit 10 is connected to one end of the wire rope 1 to be monitored.

[0027] Of course, in this embodiment, it may further include a power management module for providing a stable working voltage to the hydraulic tensioning unit 10, the floating induction unit 20, the intelligent control unit 30, the sequence coding unit 40 and the warning unit 50.

[0028] The working process of the wire rope monitoring and warning device in this embodiment is as follows: After the wire rope and the monitoring and warning device are installed according to the specified requirements, the system starts to work. The hydraulic tensioning unit 10 starts to measure and transmits the data to the data transmission module in real time; the data transmission module collects and integrates these data and then sends them to the floating induction unit. The positive and negative floating capture function in the floating induction unit checks whether the data of the hydraulic tensioning is within the specified range (±5 mm). After the check is completed, the information is sent to the intelligent control unit 30; the intelligent control unit 30 receives and processes the data from the floating induction unit 20. If it finds that the data is abnormal, it sends an instruction to the serial code transfer module to obtain the serial code of the corresponding warning device, and remotely archives the data through the signal transmission unit 600 and sends a warning message to the warning unit; the serial code monitoring module is responsible for real-time monitoring of the serial code; if it detects that a specific serial code does not change on time or there is an error in the internal system, it sends an instruction to the intelligent control unit, and the intelligent control unit sends the instruction to the signal transmission unit, and the signal transmission unit transmits the information to the remote end. When the remote end personnel find a problem, they arrange professional personnel to arrive at the scene for maintenance in time. When it is detected that there is an error in the serial code unit due to internal system reasons, the serial code monitoring module timely sends the information to the intelligent control unit, and the intelligent control unit sends the processed information to the serial code coordination module, and the serial code module coordinates and makes a timely coordination and recovery.

[0029] Obviously, it can be concluded that the wire rope monitoring and warning device provided in this embodiment applies an external force to the wire rope through the hydraulic tensioning unit and measures the loosening tension value acting on the wire rope and the displacement data caused thereby, and judges whether the data is abnormal through the floating induction unit and then sends feedback information to the intelligent control unit. The intelligent control unit requests the device code information at the abnormal location from the serial code unit and sends the code information and the fault details to the warning unit for alarm reminder. It can give a real-time warning. When the warning value is exceeded, it will send an alarm in advance to remind the surrounding operators to evacuate and take shelter, which will greatly improve the operation safety of the operators.

[0030] Method embodiment: The present invention also provides a wire rope monitoring and warning method, including the following steps: Step 1, measuring the loosening tension value acting on the wire rope to be monitored and the displacement data caused thereby.

[0031] Step 2, analyzing whether the loosening tension value or the displacement data is within a preset range.

[0032] Specifically, the preset range is +5 mm to -5 mm.

[0033] Step 3, receive the analysis result of whether the loosening tensile value or displacement data is within the preset range, and when the analysis result is abnormal, send an instruction to request the serial code of the warning device on the steel wire rope to be monitored where the abnormality occurs, and receive the back-transmitted device serial code information.

[0034] Specifically, when it is monitored that the two unique serial codes of the device do not change at fixed time, this information is transmitted to the remote end, and when the remote end personnel find the problem, professional personnel are arranged to arrive at the scene for maintenance in time.

[0035] When it is monitored that the serial code has an error due to internal system reasons, coordination and recovery are made in time.

[0036] Step 4, when receiving the back-transmitted device serial code information, turn on the voice control warning and optical warning.

[0037] Specifically, after receiving the serial code, the intelligent management module confirms which device has a problem according to the code. Then, the intelligent management unit sends this information together with the fault details to the warning unit to initiate corresponding warning measures. In summary, the present invention breaks through the traditional manual inspection method, reduces the labor and construction costs, and greatly improves the detection accuracy and monitoring efficiency; and can give real-time warnings. When the warning value is exceeded, an alarm will be issued in advance to remind the surrounding operators to evacuate and take shelter, which will greatly improve the operation safety of the operators.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention also intends to include these modifications and variations.
