DETAILED DESCRIPTION

[0036] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Example 1:

[0038] The present invention provides a multi-parameter integrated monitoring line-laying pulley, such as Figure 1 As shown, it includes: a pulley 101, a piezoelectric array module 106, a self-charging and signal output module 107, a suspension device and a signal receiving, processing and transmitting module 103;

[0039] The bearing of the pulley 101 is mounted on the suspension device, and the suspension device is used to be suspended on the transmission tower so that the transmission line on the transmission tower passes through the pulley 101. The piezoelectric vibrator module 106 is arranged on the wheel groove of the pulley 101;

[0040] The self-charging and signal output module 107 and the signal receiving, processing and transmitting module 103 are connected via electrical signals;

[0041] The piezoelectric vibrator module 106 is used to monitor the force exerted on the pulley when the power line is squeezed by the power line during the process of passing through the pulley groove of the pulley 101, and transmit the measured force exerted on the pulley to the self-charging and signal output module 107;

[0042] The self-charging and signal output module 107 is used to process the received pulley force to obtain a pulley force signal, and send the pulley force signal to the signal receiving, processing and transmitting module 103;

[0043] The signal receiving, processing and transmitting module 103 is used to send the force signal of the pulley to the monitoring background, so that the monitoring background can monitor the line-paying pulley.

[0044] The suspension device is used to mount pulley 101 and suspend it from the transmission tower. This device keeps pulley 101 and the power line passing through it suspended in the air. Using pulley 101 to pay out power lines reduces friction between the power line and the outside world, reduces wear on the power line itself, and thus increases its service life. The self-charging and signal output module 107 is secured to the hub of pulley 101, ensuring it remains relatively stationary with the piezoelectric array module 106, minimizing interference with the piezoelectric array 202.

[0045] The signal receiving and processing unit of the signal receiving, processing and transmission module 103 is equivalent to a relay station, which receives the force signal of the pulley from the self-charging and signal output module 107 and sends it from high altitude to the ground end through wireless networking. Its basic working process is: the reader sends a radio frequency signal of a certain frequency through the transmitting antenna. When the radio frequency card enters the working area of ​​the transmitting antenna, an induced current is generated, and the radio frequency card obtains energy and is activated; the radio frequency card sends its own coding and other information through the built-in transmitting antenna of the card; the system receiving antenna receives the carrier signal sent from the radio frequency card, and transmits it to the reader through the antenna regulator. The reader demodulates and decodes the received pulley force signal and then sends it to the background main system for relevant processing; the main system determines the legitimacy of the card based on logical operations, makes corresponding processing and control for different settings, and sends command signals to control the action of the actuator.

[0046] Different contactless transmission methods are fundamentally different in terms of coupling mode (inductive-electromagnetic), communication process (FDX, HDX, SEQ), data transmission method from RFID card to reader (load modulation, backscattering, high-order harmonics) and frequency range. However, all readers are very similar in functional principles and the design structure determined by them. All readers can be simplified into two basic modules: high-frequency interface and control unit.

[0047] The high-frequency interface consists of a transmitter and a receiver. Its functions include: generating high-frequency transmission power to activate and provide energy to the RFID card; modulating the transmission signal to transmit the pulley force signal transmitted by the pay-out pulley to the RFID card; and receiving and demodulating the high-frequency signal from the RFID card. The high-frequency interface design of different RFID systems varies.

[0048] The reader's control unit functions include: communicating with the application system software and executing commands sent by the application system software; controlling the communication process with the RFID card (master-slave principle); and encoding and decoding signals. For some special systems, additional functions include executing anti-collision algorithms, encrypting and decrypting data to be transmitted between the RFID card and the reader, and performing identity authentication between the RFID card and the reader.

[0049] The reading and writing distance of the RFID system is a critical parameter.

[0050] Currently, long-range RFID systems are still very expensive, so finding ways to increase their read and write distances is crucial. Factors influencing RFID card read and write distances include the antenna operating frequency, the reader's RF output power, the reader's receiver sensitivity, the RFID card's power consumption, the Q value of the antenna and resonant circuit, the antenna orientation, the degree of coupling between the reader and the RFID card, and the energy received by the RFID card itself and the energy required to transmit information. For most systems, the read and write distances are different, with the write distance being approximately 40% to 80% of the read distance.

[0051] The signal receiving, processing and transmission module 103 is used to process the information on the force exerted on the pulley transmitted by the self-charging and signal output module 107, obtain the pressure signal, frequency signal and envelope angle signal, and determine whether the obtained pressure signal, frequency signal and envelope angle signal are in normal values, thereby determining whether the transmission line has not deviated from the track of the pulley 101 during the evolution process, and whether the pressure, speed and envelope angle values ​​measured on the pulley 101 are in normal values. When an abnormality occurs, timely adjustments can be made to increase the service life of the pulley 101 and reduce damage.

[0052] like Figure 2 As shown, the piezoelectric array module 106 is a piezoelectric array composed of a plurality of groups of piezoelectric arrays 202 spaced apart on the wheel grooves of the pulley (101).

[0053] The piezoelectric array can more accurately obtain the excitation information generated when the transmission line passes through, and the piezoelectric array can monitor the data generated by the transmission line at different positions in the pulley 101 groove and at the groove curvature, and judge whether the transmission line deviates from the groove based on the data.

[0054] The piezoelectric array can obtain pressure data generated at different times on the same track and transmit the obtained data to the signal receiving, processing and transmission module 103, which further calculates the rotation speed of the pulley 101 and the value of the envelope angle through the rotation speed and frequency signal.

[0055] Specifically, the self-charging and signal output module 107 includes a node MCU, a pressure signal processing unit, a frequency signal processing unit, a pressure signal readable parameter value, and a frequency signal readable parameter value;

[0056] The node MCU is used to convert the force applied to the pulley into data to obtain a pressure signal, and calculate a frequency signal based on the time interval of the pressure signal transmission;

[0057] The pressure signal processing unit is used to convert the pressure signal into a parameter value readable by the pressure signal;

[0058] The frequency signal processing unit is used to convert the frequency signal into a frequency signal readable parameter value.

[0059] The node MCU is used to calculate data, and calculates the force on the pulley received from the piezoelectric vibrator module 106 through the circumference of the pulley 101, the interval of the force transmission on the pulley, and the force duration and the change of the force on the pulley from the start of signal transmission to the end of signal transmission by the piezoelectric vibrator module 106 after the transmission line passes through the pulley 101, so as to obtain the force signal, frequency signal and envelope angle signal of the pulley. Further, the node MCU transmits the electrical signal to the pressure signal processing unit, the frequency signal conversion unit and the envelope angle signal processing unit respectively, so as to obtain the readable pressure signal readable parameter value, the frequency numerical readable parameter value and the envelope angle readable parameter value, and transmits the obtained pressure signal readable parameter value, frequency numerical readable parameter value and envelope angle readable parameter value to the signal receiving, processing and transmitting module 103. The signal receiving, processing and transmitting module 103 processes the obtained parameter values ​​and transmits them to the monitoring background to realize the monitoring of the line-laying pulley.

[0060] Specifically, a wear-resistant rubber ring 203 is provided on the upper surface of the wheel groove of the pulley 101 . A wear-resistant colloid layer 201 is bonded to the wear-resistant rubber ring 203 . The piezoelectric vibrator module 106 is disposed in the wear-resistant colloid layer 201 . The wear-resistant colloid layer 201 is convex.

[0061] The wear-resistant colloid layer 201 is bonded to the upper end of the wear-resistant rubber ring 203 and has sufficient toughness and ductility to meet the deformation requirements of the piezoelectric array 202 .

[0062] A spindle 108 is provided inside the pulley 101 , and the pulley 101 and the spindle 108 are connected via a hub.

[0063] Specifically, the lower ends of the piezoelectric array module 106 and the self-charging and signal output module 107 are fastened to the hub of the pulley 101 by bolts.

[0064] The wear-resistant colloid layer 201 and the wear-resistant rubber ring 203 can both protect the pulley 101 and the power transmission line transmitted on the pulley 101, increase the service life, and reduce the degree of wear. The wear-resistant colloid layer 201 and the wear-resistant rubber ring 203 can be replaced at any time according to the degree of damage.

[0065] like Figure 3 As shown, the self-charging and signal output module 107 is connected to the piezoelectric array module 106 via a wire 205 .

[0066] The self-charging and signal output module 107 ensures its own continuous power supply through the action of the piezoelectric nanogenerator to prevent the problem of insufficient power supply for the speed monitoring and pressure monitoring devices, and to adapt to different construction environments.

[0067] Specifically, the piezoelectric array module 106 is disposed in the wheel groove of the pulley 101 , the self-charging and signal output module 107 is disposed on the hub of the pulley 101 , and the signal receiving and processing module is disposed on the suspension device.

[0068] The suspension device includes: a frame 104, a connecting plate 102 and a bottom beam 109;

[0069] The frame 104 is arranged on both sides of the pulley 101, one end of the frame 104 is connected to a connecting plate 102, and the end of the frame 104 away from the connecting plate 102 is connected to a bottom beam 109, and the pulley 101 is connected and fixed by the frame 104 and the bottom beam 109; the pulley 101 is suspended to the transmission tower through the connecting plate 102.

[0070] The signal receiving, processing and transmitting module 103 can be placed in the middle of the pulley connecting plate 102 and can receive signals with better quality.

[0071] The connecting plate 102 is a triangular structure, and a shackle 105 is provided at one triangular end of the connecting plate 102. The other end of the shackle 105 is connected to a rotary connector 100, and is connected to the transmission tower through the rotary connector 100.

[0072] The signal receiving, processing and transmitting module 103 is fixed to the middle section of the connecting plate 102 away from the shackle 105 by bolts.

[0073] Specifically, one or more pulleys 101 are provided according to the number of transmission lines, and the multiple pulleys 101 are coaxially connected.

[0074] Generally, three-wheel pulleys are used, which can lay multiple transmission lines at one time.

[0075] The present invention adds an integrated speed monitoring and pressure monitoring device to the three-wheeled wire-laying pulley to monitor the real-time situation of the pulley during wire-laying, thereby judging whether the wire-laying is smooth and preventing the pulley from being damaged by excessive pressure during the wire-laying process. In addition, the pulley will not be instable due to excessive rotation caused by overspeed or jamming of the wire-laying, which will cause damage to both the pulley and the transmission line. The piezoelectric nanogenerator ensures its own power supply to adapt to different construction environments.

[0076] Example 2:

[0077] Based on the same inventive concept, the present invention also provides a Figure 4 A multi-parameter integrated monitoring method for a pay-out pulley is shown, comprising:

[0078] The force on the pulley obtained by the piezoelectric array module 106;

[0079] The force applied to the pulley is converted into a force signal applied to the pulley through the self-charging and signal output module 107;

[0080] The signal receiving, processing and transmitting module 103 sends the force signal of the pulley to the monitoring background to monitor the rotation speed and pressure of the pay-off pulley 101 .

[0081] In order to prevent the pulley from being damaged due to excessive pressure during the wiring process, a pressure monitoring device based on piezoelectric sensing is added for real-time monitoring, so as to detect pressure abnormalities in time and make timely adjustments.

[0082] In order to prevent the pulley from rotating too fast due to overspeed or jamming of the wire, which may cause instability and damage to both the pulley and the transmission line, a speed monitoring device based on piezoelectric sensing is added for real-time monitoring, so as to detect pressure abnormalities in time and make timely adjustments.

[0083] In order to prevent abnormal transmission line length and sag conditions from tower to tower, an envelope angle monitoring device based on piezoelectric sensing is added for real-time monitoring, so as to detect envelope angle abnormalities in time and make timely adjustments.

[0084] The force signal exerted on the pulley 101 includes at least one or more of the following: a pressure signal, a frequency signal, and an envelope angle signal.

[0085] The acquisition of the pressure signal, frequency signal and envelope angle signal includes:

[0086] When the transmission line passes through the pulley 101, the force exerted on the pulley is converted into the pressure signal through the self-charging and signal output module 107;

[0087] The frequency signal is obtained by obtaining the transmission frequency of the force applied to the pulley according to the self-charging and signal output module 107;

[0088] During the rotation of the pulley 101 , the piezoelectric array module 106 obtains the envelope angle signal from the duration of the force applied to the pulley and the rotation angle of the pulley 101 .

[0089] The pressure signal, frequency signal and envelope angle signal are processed by the self-charging and signal output module 107 to obtain readable parameter values, and each readable signal is transmitted to the monitoring background via the receiving and processing module 103 to realize the monitoring of the line-laying pulley.

[0090] When the transmission line passes through the piezoelectric array module 106 on the pulley 101, the process further includes:

[0091] The self-charging and signal output module 107 provides energy for the piezoelectric array module 106;

[0092] When the transmission line passes through the slide 101, vibration excitation is generated, and the vibration excitation is transmitted to the self-charging and signal output module 107, and converted into energy by the self-charging and signal output module 107 and transmitted to the piezoelectric array module 106 to provide energy for the piezoelectric array module 106.

[0093] like Figure 5 As shown, when the transmission line passes through the pulley, vibration excitation is generated. When the transmission line passes through the pulley 101, the wear-resistant gel layer 201 is squeezed, so that the piezoelectric vibrator module 106 in the wear-resistant gel layer 201 is compressed and deformed, and further the piezoelectric sheet in the piezoelectric vibrator module 106 is deformed, generating a polarization effect. The excitation generates excess electricity after passing through the energy collection circuit, supercapacitor, voltage stabilizing circuit, node MCU, and energy dissipation circuit in the self-charging and signal output module 107 and is stored in the supercapacitor. After passing through the node MCU, it passes through the frequency signal conversion unit, the pressure signal unit and the envelope angle signal processing unit respectively, and finally is delivered to the signal receiving and processing module.

[0094] Specifically, the self-charging and signal output module 107 converts the pulley force into a pulley force signal, and transmits the pulley force signal to the signal receiving, processing and transmitting module 103, including:

[0095] After the force exerted on the pulley 101 of the piezoelectric array module 106 enters the self-charging and signal output module 107, it is converted into a force signal exerted on the pulley 101 through the energy conversion unit in the self-charging and signal output module 107. The energy conversion unit in the self-charging and signal output module 107 transmits the force signal exerted on the pulley 101 to the signal output module 103.

[0097] Based on the same inventive concept, the present invention also provides a Figure 4 The multi-parameter integrated monitoring system for a wire-laying pulley shown includes: a multi-parameter integrated monitoring wire-laying pulley and a monitoring background;

[0098] The monitoring background is used to receive the force signal of the pulley transmitted by the wire-paying pulley, and judge the working status of the wire-paying pulley according to the force signal of the pulley.

[0099] Example 4:

[0100] Based on the same inventive concept, the present invention also provides a Figure 4 The computer-readable storage medium of the multi-parameter integrated monitoring method for monitoring a pay-out pulley shown is specifically a computer-readable storage medium (Memory).
