[0002] In power transmission systems, transmission towers, as the core structure supporting high-voltage lines, directly affect the safety and reliability of the power grid operation due to the stability of their mechanical properties. In the field of angle steel reinforcement for transmission towers, traditional mechanical fastening and welding technologies have long faced reliability bottlenecks. With the rise of electromagnetic pulse (EMP) crimping technology, which achieves heat-free connection through instantaneous high-energy electromagnetic force-driven metal plastic deformation, an innovative approach to angle steel reinforcement has been provided. This technology avoids performance degradation caused by heat input or mechanical loosening in traditional methods, and results in higher atomic-level bonding strength at the connection interface.

[0003] However, existing electromagnetic pulse (EMP) devices are mostly fixed structures, which present challenges in remote locations such as fields and mountains, including difficulties in transportation and limited operating radius, severely restricting the large-scale application of this technology in power transmission tower maintenance. Furthermore, these devices typically rely on external power supplies, rendering them unusable in areas without power or with unstable power supply. Moreover, the performance of existing equipment in areas such as charging control and status monitoring needs improvement; it is difficult to precisely control the output parameters of the EMP and monitor the equipment's operating status in real time and accurately, resulting in insufficient reliability and stability.

[0023] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 This invention provides an electromagnetic pulse fastening system for angle steel of power transmission towers, comprising: Tracked subsystem 1: The tracked subsystem 1 is rigidly connected to the control panel 00 to enable movement and position adjustment in the working environment.

[0025] The track subsystem 1 employs a track structure, consisting of multiple track plates 11 connected by pins 12 to form a continuous track ring. This structure increases the contact area with the ground, distributes the equipment weight, and improves its passability in complex terrains (such as muddy or rugged surfaces). The drive wheel 13 is mounted at the front of the track subsystem 1, its teeth meshing with the track plates 11. By rotating the drive wheel 13, the track plates 11 are moved using gear transmission principles, enabling the equipment to move forward, backward, and turn. The support wheel 14 is mounted in the middle and connected to the chassis 16 via bearings 15, supporting the weight of the equipment while reducing frictional resistance during track movement. The tension wheel 17 is mounted side-by-side with the drive wheel 13 and support wheel 14, used to adjust the track tension, ensuring the track maintains a suitable tension at all times. This prevents slippage due to excessive looseness or increased wear due to excessive tightness, thus ensuring stable and efficient movement and positioning of the equipment in the operating environment.

[0026] Charging control platform 2 includes a power supply 21, a capacitor 22, an SCR voltage regulator 23, and a voltage sensor 26. The power supply 21 is connected to the capacitor 22, and the voltage sensor 26 is connected to both ends of the capacitor 22. The charging control platform 2 regulates the charging process of the capacitor 22 through the SCR voltage regulator 23.

[0027] The power supply unit 21 provides charging energy to the capacitor 22, and the voltage sensor 26 monitors the voltage across the capacitor 22 in real time. The SCR power regulator 23 plays a crucial regulatory role during the charging process, working collaboratively with its internal silicon controlled rectifier 231, trigger circuit 232, and adjusting potentiometer 233. Adjusting the potentiometer 233 changes the resistance value, thereby altering the signal voltage input to the trigger circuit 232. The trigger circuit 232 generates a corresponding trigger pulse based on this signal, controlling the conduction time and conduction angle of the silicon controlled rectifier 231. By adjusting the conduction angle, the SCR power regulator 23 can precisely control the current and voltage input to the capacitor 22, ensuring that the capacitor 22 charges according to the set charging curve, guaranteeing the stability and accuracy of the charging process, and providing a guarantee for the stable output of subsequent electromagnetic pulses.

[0028] Electromagnetic pulse generation subsystem 3: The electromagnetic pulse generation subsystem 3 is connected to the charging control platform 2. The electromagnetic pulse generation subsystem 3 is used to generate electromagnetic pulses to achieve the fastening operation of the angle steel of the power transmission tower.

[0029] The charging control platform 2 provides power to the electromagnetic pulse generation subsystem 3. When the capacitor 22 reaches the set voltage, the switching element 323 closes, and the capacitor 22 discharges to the electromagnetic pulse generation subsystem 3. The upper pressing mold 311 and lower pressing mold 312 of the crimping device 31 are connected by a hinge to form an angle steel working chamber for placing the angle steel. The upper magnetic coil 321 and lower magnetic coil 322 of the magnetic collecting device 32 are connected to the upper pressing mold 311 and lower pressing mold 312 respectively, forming a cavity with the same center as the working chamber. When the capacitor 22 discharges, current flows through the magnetic coils. According to the principle of electromagnetic induction, the magnetic coils generate a strong local magnetic field, which is concentrated in the working chamber. This causes the angle steel of the transmission tower and the reinforcing angle steel located therein to undergo plastic deformation and fusion under the action of electromagnetic force, thereby achieving the fastening of the transmission tower angle steel. The limiting device 33 is used to position and fix the angle steel, ensuring accurate fastening position and improving crimping quality.

[0030] Monitoring and feedback subsystem 4: The monitoring and feedback subsystem 4 is used to monitor the operating status of the electromagnetic pulse fastening system of the angle steel of the power transmission tower in real time.

[0031] The monitoring feedback subsystem 4 utilizes multiple sensors and controllers 502 to collaboratively monitor the system's operating status in real time. A temperature sensor 41, installed inside the capacitor 22, monitors its temperature in real time, as the capacitor 22 generates heat during charging and discharging; excessively high temperatures can affect its performance and lifespan, and even cause safety issues. A current sensor 24 monitors the current in the charging circuit, and a voltage sensor 26 monitors the voltage across the capacitor 22. This data is transmitted to the charging control module 25 and the microcontroller 45. Based on the received data, the microcontroller 45 analyzes the impact of temperature fluctuations on the charging current and voltage by running preset control algorithms, such as a temperature compensation algorithm, and dynamically adjusts the PWM signal (pulse width modulation signal) and charging parameters to ensure a stable charging process. An operation panel 42 is located on the front of the control panel 00, allowing operators to view system operating data (such as current, voltage, and temperature) in real time and control the system using start / stop buttons and parameter adjustment buttons. Alarm 43 is connected to current sensor 24, SCR voltage regulator 23, and temperature sensor 41. When abnormal conditions such as overvoltage, overcurrent, or overtemperature are detected, alarm 43 issues a warning signal to remind operators to handle the situation promptly and ensure the safe operation of the system. Data storage 44 is used to store data such as operating temperature, voltage, current, and alarm records, facilitating subsequent analysis of system operation and troubleshooting. It communicates with microcontroller 45 via an SPI interface to achieve fast data transmission and storage management.

[0032] See Figure 9 In this embodiment, a photovoltaic power supply system 5 is also included, which includes a photovoltaic panel 501, a controller 502, an inverter 503, a load 235, a monitor 504, and a battery 505. Photovoltaic panel 501: The photovoltaic panel 501 is used to convert solar energy into electrical energy to power the electromagnetic pulse fastening system of the angle steel of the power transmission tower. The output end of the photovoltaic panel 501 is connected to the input end of the controller 502.

[0033] Specifically, the photovoltaic panel 501 operates based on the photoelectric effect. When sunlight shines on the photovoltaic panel 501, photons interact with the semiconductor material within the panel, transferring energy to electrons. This allows the electrons to gain enough energy to break free from the atoms, creating electron-hole pairs. These electrons and holes move directionally under the influence of the electric field within the photovoltaic panel 501, forming an electric current and achieving a direct conversion from solar energy to electrical energy. The generated electrical energy is transmitted to the controller 502 through the output terminal, providing green and sustainable energy for the entire system.

[0034] Controller 502: The controller 502 receives electrical energy from the photovoltaic panel 501 and distributes electrical energy according to the power demand of the load 235 and the power status of the battery 505.

[0035] Specifically, the controller 502 acts as the energy management hub, monitoring the power demand of the load 235 and the charge status of the battery 505 in real time. When the load 235 has low demand and the battery 505 is not fully charged, the controller 502 directs excess power generated by the photovoltaic panel 501 to the battery 505 for charging, thus storing energy. When the load 235 has high demand or the photovoltaic panel 501 is not generating enough power, the controller 502 prioritizes allocating power from the photovoltaic panel 501 to the load 235. If the photovoltaic panel 501 is not generating enough power, it releases power from the battery 505 to supplement it, ensuring that the load 235 always has a stable power supply, improving energy efficiency, and ensuring the normal operation of the system under different operating conditions.

[0036] Inverter 503: The inverter 503 converts the DC power input to the controller 502 into AC power suitable for the load 235.

[0037] Specifically, the inverter 503 converts direct current (DC) into alternating current (AC) through the switching action of power electronic devices (such as IGBTs). Its operation generally consists of two stages: DC chopping and inversion. First, by controlling the switching on and off of the power electronic devices, the DC is chopped into a series of square wave signals with variable pulse widths. Then, the filter circuit 236 shapes and filters these square wave signals to produce an AC output close to a sine wave, meeting the AC requirements of most electrical equipment and ensuring the normal operation of various loads 235 in the electromagnetic pulse fastening system of the transmission tower angle steel.

[0038] Monitor 504: The monitor 504 is used to monitor the operating parameters of the photovoltaic panel 501, the controller 502, the inverter 503, and the battery 505.

[0039] Specifically, the monitor 504 is connected to the photovoltaic panel 501, controller 502, inverter 503, and battery 505 via sensors to collect real-time operating parameters of these devices, such as the output voltage, current, and power of the photovoltaic panel 501; the operating status and power distribution of the controller 502; the input and output voltage, current, and frequency of the inverter 503; and the voltage, current, and charge of the battery 505. The monitor 504 analyzes and processes this data. If any abnormal parameters are detected, such as excessively high or low voltage, current overload, or abnormal fluctuations in charge, it promptly issues an alarm signal and uploads the data to the system's monitoring center or stores it locally. This allows operators to view and analyze the system's operating status at any time, promptly identify potential problems, and perform maintenance, ensuring the stable and reliable operation of the photovoltaic power supply system 5.

[0040] See Figure 1 In one possible embodiment, the track subsystem 1 includes a plurality of track plates 11 connected by pins 12 to form a continuous track ring. A drive wheel 13 is installed at the front of the track subsystem 1, and the drive wheel 13 meshes with the track plates 11 in a toothed manner. A support wheel 14 is installed in the middle of the track subsystem 1, and the support wheel 14 is connected to the chassis 16 through a bearing 15. A tension wheel 17 is installed side by side on the drive wheel 13 and the support wheel 14.

[0041] Specifically, the track plates 11 are connected to form track rings via pins 12. This connection method ensures both the flexibility of the track and the ability to withstand significant tensile and frictional forces. The tooth profile of the drive wheel 13 precisely matches that of the track plate 11. When the drive wheel 13 rotates under the drive of a power source (such as an electric motor), its teeth mesh with the teeth of the track plate 11. According to the gear transmission principle, the rotational force of the drive wheel 13 is converted into the linear motion force of the track plate 11, propelling the equipment forward or backward. The support wheel 14 is located in the middle of the track subsystem 1 and is connected to the chassis 16 via a bearing 15. The bearing 15 reduces the friction between the support wheel 14 and the chassis 16, allowing the support wheel 14 to rotate flexibly. Simultaneously, the support wheel 14 bears part of the equipment's weight, distributing it evenly across the track, reducing localized pressure on the track, and extending its service life. The tension wheel 17 adjusts the track tension; by adjusting the position of the tension wheel 17, the track tension can be changed. When the track is too loose, the equipment is prone to slippage, affecting driving force and driving stability; when the track is too tight, it increases friction between the track and other components, accelerating track wear. The tension wheel 17 adjusts the track tension according to actual conditions through its own adjustment mechanism (such as screws, springs, etc.) to ensure that the track is always in optimal working condition.

[0042] See Figure 3 In one possible embodiment, the charging control platform 2 further includes a current sensor 24 and a charging control module 25; the power supply device 21 includes a charging controller 211 and a power module 212; the charging controller 211 is used to manage the charging process of the power module 212; the power module 212 provides an initial charging current to the capacitor 22; The current sensor 24 is installed in the charging circuit to monitor the charging current of the capacitor 22 in real time; the current sensor 24 transmits the current data to the charging control module 25, and the charging control module 25 adjusts the output of the power module 212 according to the feedback from the voltage and current sensor 24.

[0043] Specifically, the charging controller 211 intelligently manages the charging process of the power module 212. Based on the characteristics of the power module 212 (such as battery type and capacity) and a preset charging strategy, it controls the charging voltage, current, and charging time of the power module 212 to ensure safe and efficient charging. Under the control of the charging controller 211, the power module 212 provides the initial charging current to the capacitor 22. A current sensor 24 is installed in the charging circuit and uses principles such as electromagnetic induction or the Hall effect to monitor the magnitude of the charging current in real time, transmitting the current data to the charging control module 25 in the form of an electrical signal. The charging control module 25, as the core control unit of the charging control platform 2, receives feedback signals from the voltage sensor 26 and the current sensor 24, and analyzes and processes them through its internal microprocessor or logic circuit. According to a preset control algorithm (such as a PID control algorithm), the charging control module 25 adjusts the output voltage and current of the power module 212 to make the charging process of the capacitor 22 more stable and precise. For example, when the charging current of capacitor 22 is detected to be too large, the charging control module 25 reduces the output voltage of the power module 212 to reduce the charging current; when the charging current is detected to be too small, the output voltage of the power module 212 is appropriately increased to speed up the charging speed, ensuring that capacitor 22 is charged according to the ideal charging curve, thereby improving charging efficiency and charging quality.

[0044] See Figure 7 In one possible embodiment, the SCR power regulator 23 includes a silicon controlled rectifier 231, a trigger circuit 232, an adjustment potentiometer 233, a power input circuit 234, a load 235, and a filter circuit 236. One end of the power input circuit 234 is connected to the silicon controlled rectifier 231, and the silicon controlled rectifier 231 is connected in series with the adjustment potentiometer 233. The adjustment potentiometer 233 adjusts the input signal by changing the resistance value, thereby affecting the trigger circuit 232. A switching element 323 is also connected between the power input circuit 234 and the capacitor 22. The switching element 323 is used to control the on / off state of the circuit to control the charging and discharging process of the electromagnetic pulse generation subsystem 3.

[0045] Specifically, the power input circuit 234 connects an external power source (such as AC mains power) to the SCR power regulator 23, providing power to the entire voltage regulation circuit. The silicon controlled rectifier 231 is one of the core components of the SCR power regulator 23, possessing unidirectional conductivity and controllable conduction characteristics. The adjusting potentiometer 233 is connected in series with the silicon controlled rectifier 231. By changing its resistance value, it alters the current in the circuit, thereby regulating the voltage signal input to the trigger circuit 232. When the trigger pulse arrives, the silicon controlled rectifier 231 conducts, and current flows through it to the load 235 (in this system, the load 235 is mainly the capacitor 22). By adjusting the resistance value of the adjusting potentiometer 233, the timing of the trigger pulse generated by the trigger circuit 232 can be changed, i.e., controlling the conduction time and conduction angle of the silicon controlled rectifier 231, thereby precisely controlling the voltage and current output to the capacitor 22. The switching element 323 is connected between the power input circuit 234 and the capacitor 22 to control the on / off state of the circuit. During charging, switch element 323 closes, and capacitor 22 begins charging. When capacitor 22 is fully charged or charging needs to be stopped, switch element 323 opens, cutting off the charging circuit. During discharging, switch element 323 controls the timing of capacitor 22 discharging into electromagnetic pulse generation subsystem 3. Filter circuit 236 is generally composed of inductors, capacitors, and other components, connected to the output terminal of SCR power regulator 23. Because silicon controlled rectifier 231 generates voltage fluctuations and pulse interference during conduction and turn-off, filter circuit 236 utilizes the energy storage characteristics of inductors and capacitors to filter the output voltage, smoothing the irregular voltage waveform into a more stable DC voltage. This reduces the impact of voltage fluctuations on the charging process of capacitor 22 and electromagnetic pulse generation subsystem 3, improving the system's stability and reliability.

[0046] See Figure 4 , Figure 5 and Figure 6 In one possible embodiment, the electromagnetic pulse generation subsystem 3 includes a pressing device 31, a magnetic collecting device 32, and a limiting device 33. The pressing device 31 is connected to the sliding rail 35 via the slider 34. The pressing device 31 includes an upper pressing die 311 and a lower pressing die 312. The upper pressing die 311 and the lower pressing die 312 are rotatably connected by a hinge to form an angle steel working chamber. An operating handle 313 is provided on one side of the upper pressing die 311, and a locking mechanism 314 is provided below the operating handle 313.

[0047] Specifically, the slider 34 of the crimping device 31 cooperates with the sliding rail 35, enabling the crimping device 31 to move precisely within a certain range, facilitating the adjustment of the crimping position. The upper crimping mold 311 and the lower crimping mold 312 are connected by a hinge to form an angle steel working chamber. This structural design allows the angle steel of the transmission tower and the reinforcing angle steel to be stably placed in the chamber for fastening operations. The operating handle 313 allows the operator to manually control the opening and closing of the upper crimping mold 311. When it is necessary to place or remove the angle steel of the transmission tower, the operator can open the upper crimping mold 311 through the operating handle 313; when performing crimping operations, the operator closes the upper crimping mold 311 and uses the locking mechanism 314 to tightly fix the upper crimping mold 311 and the lower crimping mold 312 together, ensuring that they will not loosen during the fastening process and guaranteeing the stability and reliability of the crimping.

[0048] The magnetic collecting device 32 includes an upper magnetic collecting coil 321 and a lower magnetic collecting coil 322. The upper magnetic collecting coil 321 is connected to the upper pressing mold 311, and the lower magnetic collecting coil 322 is connected to the lower pressing mold 312. The upper magnetic collecting coil 321 and the lower magnetic collecting coil 322 together form a cavity with the same diameter as the angle steel working chamber. The upper magnetic collecting coil 321 and the lower magnetic collecting coil 322 are connected to the capacitor 22 through the switching element 323.

[0049] Specifically, the upper magnetic collecting coil 321 and the lower magnetic collecting coil 322 of the magnetic collecting device 32 are tightly connected to the upper pressing mold 311 and the lower pressing mold 312, respectively, forming a cavity with the same center as the working chamber of the pressing device 31. This structural design enables the magnetic field to be highly concentrated in the working chamber, improving the magnetic field utilization efficiency. When the capacitor 22 is charged to the set voltage value, the switching element 323 closes, and the capacitor 22 discharges to the magnetic collecting coil. According to the law of electromagnetic induction, a magnetic field is generated when current passes through the upper and lower magnetic collecting coils 322. Due to the relative position and winding method of the two magnetic collecting coils, their magnetic fields are superimposed in the working chamber, forming a strong local magnetic field. This magnetic field acts on the angle steel located in the working chamber, subjecting the angle steel to a strong electromagnetic force. Under the action of the electromagnetic force, the metal materials of the transmission tower angle steel and the reinforcing angle steel undergo plastic deformation, achieving a tight connection and completing the fastening operation.

[0050] The limiting device 33 has receiving tubes 331 on both sides, the receiving tubes 331 penetrate the angle steel groove 332, and a rubber protective sleeve 333 connects the receiving tubes 331 and the angle steel groove 332; a rotary button 334 is provided on one side of the limiting device 33, and the rotary button 334 is connected to the angle steel positioning clamp inside the limiting device 33.

[0051] Specifically, the receiving cylinder 331 of the limiting device 33 guides the angle steel into the reinforcement area, and the through-hole design of the angle steel groove 332 facilitates the placement and positioning of the angle steel. A rubber protective sleeve 333 connects the receiving cylinder 331 and the angle steel groove 332, protecting the angle steel and preventing scratches or wear during insertion and positioning. The rotary button 334 is connected to the angle steel positioning clamp inside the limiting device 33. The operator can adjust the position of the angle steel positioning clamp by rotating the button 334, thereby precisely adjusting the position of the angle steel to ensure it is in the optimal position during tightening, improving tightening quality and guaranteeing the connection accuracy and stability of the angle steel.

[0052] See Figure 8 In one possible embodiment, the monitoring feedback subsystem 4 includes a temperature sensor 41, an operation panel 42, an alarm 43, a microcontroller 45, and a data storage device 44. The temperature sensor 41 is installed inside the capacitor 22; the operation panel 42 is located on the front side of the operation table 00, and the operation panel 42 is provided with a display 421, a start / stop device button and an adjustment working parameter button; The alarm 43 is connected to the current sensor 24, the SCR power regulator 23 and the temperature sensor 41; the alarm 43 is used to issue a warning signal when an abnormal situation of overvoltage, overcurrent or overtemperature occurs during the charging process.

[0053] Specifically, temperature sensor 41 is installed inside capacitor 22 to monitor the temperature change of capacitor 22 in real time during charging and discharging. Since capacitor 22 generates heat during charging and discharging, excessively high temperatures can affect its performance and lifespan, and even cause safety issues. Temperature sensor 41 converts the temperature signal into an electrical signal and transmits it to microcontroller 45. Operation panel 42 is located on the front of the control panel 00, facilitating interaction between the operator and the system. Display 421 displays real-time system operating parameters such as current, voltage, temperature, pulse intensity, and applied pressure, allowing the operator to intuitively understand the system's operating status. The start / stop button controls the start and stop of the entire electromagnetic pulse fastening system for the transmission tower angle steel. The adjust operating parameters button allows the operator to adjust system operating parameters such as charging voltage, current, and crimping time according to actual operational needs. The alarm 43 is connected to the current sensor 24, the SCR power regulator 23 and the temperature sensor 41. When the current sensor 24 detects overcurrent, the SCR power regulator 23 outputs overvoltage or the temperature sensor 41 detects overtemperature or other abnormal conditions, the alarm 43 will receive the corresponding signal and issue a warning signal (such as an audible and visual alarm) to remind the operator to take timely measures to avoid equipment damage or safety accidents.

[0054] The data storage 44 is used to store operating temperature, voltage, current, and alarm record data. The data storage 44 communicates with the microcontroller 45 through an SPI interface. The microcontroller 45 is used to analyze the impact of temperature fluctuations on charging current and voltage through a temperature compensation algorithm, and dynamically adjust the PWM signal and charging parameters.

[0055] Specifically, the data memory 44 employs non-volatile storage technology (such as EEPROM, FLASH, etc.) to store important data during system operation, including temperature, voltage, current, and alarm records. This data provides a basis for system fault diagnosis, performance optimization, and operational status analysis. The SPI interface (Serial Peripheral Interface) is a high-speed, synchronous serial communication interface used to achieve fast data transmission between the microcontroller 45 and the data memory 44. The microcontroller 45 writes data to or reads data from the data memory 44 through the SPI interface, ensuring accurate data storage and fast access, so as to effectively monitor and analyze the operational status of the electromagnetic pulse fastening system for the angle steel of the power transmission tower, and provide data support for system optimization and fault diagnosis.

[0056] Among them, the microcontroller 45 is used to analyze the impact of temperature fluctuations on charging current and voltage through a temperature compensation algorithm, and dynamically adjust the PWM signal and charging parameters.

[0057] Specifically, the microcontroller 45 incorporates a temperature compensation algorithm. This algorithm is based on a pre-defined mathematical model and performs calculations using real-time temperature data of the capacitor 22 collected by the temperature sensor 41. Since the electrical properties of the capacitor 22 change with temperature—for example, as the temperature rises, the equivalent series resistance of the capacitor 22 increases—energy loss during charging increases, and the charging current and voltage are also affected. The microcontroller 45 utilizes the temperature compensation algorithm to accurately calculate the parameter values ​​needed to maintain stable charging based on temperature fluctuations.

[0058] The PWM (Pulse Width Modulation) signal is the key means for the microcontroller 45 to control the charging process. The microcontroller 45 adjusts the voltage and current output by the power module 212 by changing the duty cycle of the PWM signal (i.e., the proportion of the high level within one cycle). When the temperature rises, the microcontroller 45 appropriately reduces the duty cycle of the PWM signal according to the temperature compensation algorithm, reducing the charging current and preventing the capacitor 22 from being damaged by overheating. Conversely, when the temperature decreases, the microcontroller 45 increases the duty cycle of the PWM signal, increasing the charging current and accelerating the charging speed. Through this dynamic adjustment of the PWM signal and charging parameters, the microcontroller 45 can effectively eliminate the adverse effects of temperature fluctuations on the charging process, ensuring that the capacitor 22 can be charged stably and efficiently under different temperature environments, thus improving the reliability and stability of the electromagnetic pulse connector crimping system.

[0059] The workflow of this invention is as follows: First, system preparation and startup Equipment Inspection: Before commencing operations, operators must conduct a comprehensive inspection of the entire fastening system. Carefully examine the equipment's exterior to ensure there is no damage to the casing, loose components, or other issues. Also check that all wiring connections are secure and that plugs and sockets have no poor contact.

[0060] Photovoltaic power supply system 5 startup: After the operator turns on the system power, the photovoltaic power supply system 5 begins to work. Under sunlight, the photovoltaic panel 501 converts solar energy into electrical energy based on the photoelectric effect. The DC power generated by the photovoltaic panel 501 is output to the controller 502. The controller 502 monitors the output power of the photovoltaic panel 501, the power demand of the load 235, and the charge status of the battery 505 in real time. If there is sufficient sunlight and the power demand of the load 235 is small, the controller 502 will guide the excess power to the battery 505 for charging to store energy; if there is insufficient sunlight, or the power demand of the load 235 is large, and the power generated by the photovoltaic panel 501 is insufficient to meet the demand of the load 235, the controller 502 will allocate the power in the battery 505 to supply the load 235 together with the power generated by the photovoltaic panel 501, ensuring the stability of the system power.

[0061] System Self-Check: Simultaneously, the system performs an internal self-check. Key components in each subsystem, such as sensors and controller 502, conduct self-tests to confirm their operational status. For example, temperature sensor 41, current sensor 24, and voltage sensor 26 in the monitoring feedback subsystem 4 automatically check the accuracy of their measurement functions and the smoothness of communication lines. If an anomaly is detected, the system will display corresponding fault information on the operation panel 42, reminding operators to troubleshoot and repair.

[0062] Second, the equipment is moved to the work site. Track subsystem 1 startup: The operator starts track subsystem 1 via the track control button on the control panel 42. The power unit (such as an electric motor) starts running, transmitting power to the drive wheel 13. The drive wheel 13 begins to rotate under the action of power. Since the drive wheel 13 and the track 11 are connected by a toothed meshing method, the rotational force of the drive wheel 13 is converted into the linear motion force of the track 11.

[0063] Movement Operation: The operator precisely controls the direction and speed of the tracked subsystem 1 using the operating handle 313 or control buttons. For example, pushing the operating handle 313 forward moves the tracked subsystem 1 forward; turning the operating handle 313 left or right turns the equipment. During movement, the operator must constantly observe the surrounding environment to ensure safe movement of the equipment and avoid collisions with obstacles.

[0064] Positioning the work point: After moving the equipment to the vicinity of the angle steel fastening work point on the transmission tower, the operator fine-tunes the movement of the track subsystem 1 to ensure that the equipment's pressing device 31 is accurately aligned with the angle steel of the transmission tower. During the positioning process, positioning aids (such as laser rangefinders, cameras, etc.) on the equipment can be used to improve positioning accuracy. Simultaneously, the operator must ensure that the equipment is stable at the work point to prevent equipment shaking due to uneven ground or other reasons, which could affect the fastening quality.

[0065] Third, the charging control platform 2 is in operation. Power supply unit 21 initialization: The charging controller 211 of the power supply unit 21 starts working and initializes the power module 212 according to the preset charging strategy and the characteristics of the power module 212 (such as battery type, capacity, etc.). The charging controller 211 controls the power module 212 to output a suitable initial charging current to prepare for charging the capacitor 22.

[0066] Current and voltage monitoring: Current sensor 24 is installed in the charging circuit to monitor the magnitude of the charging current in real time. Current sensor 24 uses principles such as electromagnetic induction or the Hall effect to convert the charging current into an electrical signal and transmit it to the charging control module 25. Voltage sensor 26 is connected across capacitor 22 to monitor the voltage across capacitor 22 in real time and also transmits the voltage signal to the charging control module 25.

[0067] SCR voltage regulator 23 plays a crucial regulatory role during charging. The adjusting potentiometer 233 is connected in series with the silicon controlled rectifier 231. The operator can adjust the resistance value of the adjusting potentiometer 233 to change the current in the circuit, thereby regulating the voltage signal input to the trigger circuit 232. When the trigger pulse arrives, the silicon controlled rectifier 231 conducts, and current flows through it to the capacitor 22. By precisely adjusting the resistance value of the adjusting potentiometer 233, the timing of the trigger pulse generated by the trigger circuit 232 can be changed, thus controlling the conduction time and conduction angle of the silicon controlled rectifier 231. This precisely controls the current and voltage input to the capacitor 22, ensuring that the capacitor 22 charges according to the set charging curve.

[0068] Charging process adjustment: As the core control unit of the charging control platform 2, the charging control module 25 receives feedback signals from the voltage sensor 26 and the current sensor 24. The microprocessor or logic circuit inside the charging control module 25 analyzes and processes the feedback signals according to a preset control algorithm (such as a PID control algorithm). For example, when it detects that the charging current of capacitor 22 is too high, the charging control module 25 will reduce the output voltage of the power module 212 to decrease the charging current; when it detects that the charging current is too low, it will appropriately increase the output voltage of the power module 212 to accelerate the charging speed. Through this real-time adjustment, the charging process of capacitor 22 is ensured to be stable and accurate, improving charging efficiency and charging quality.

[0069] Fourth, electromagnetic pulse generation and crimping Capacitor 22 Discharge Preparation: When capacitor 22 has been charged to the set voltage value, the charging control platform 2 will send a signal to control the switching element 323 to close. At this time, capacitor 22 begins to discharge to the electromagnetic pulse generation subsystem 3.

[0070] Electromagnetic pulse generation: Current flows through the upper magnetic collecting coil 321 and the lower magnetic collecting coil 322 of the magnetic collecting device 32. According to the law of electromagnetic induction, a magnetic field is generated when current flows through the coil. Due to the relative position and winding design of the upper and lower magnetic collecting coils 322, the magnetic fields they generate are superimposed in the angle steel working chamber of the crimping device 31, forming a strong local magnetic field.

[0071] Fastening of transmission tower angle steel: The transmission tower angle steel and reinforcing angle steel located in the angle steel working chamber are subjected to electromagnetic force under the influence of a strong local magnetic field. The metal materials of the transmission tower angle steel and reinforcing angle steel undergo plastic deformation under the action of electromagnetic force, thereby achieving a tight connection and completing the fastening operation.

[0072] Operation of fastening device 31: The operator can conveniently control the opening and closing of the upper pressing mold 311 through the operating handle 313. When placing the angle steel, the operator opens the upper pressing mold 311 and accurately places the transmission tower angle steel and the reinforcing angle steel onto the lower pressing mold 312; then closes the upper pressing mold 311 and uses the locking mechanism 314 below the operating handle 313 to firmly fix the upper pressing mold 311 and the lower pressing mold 312 together, ensuring that the two will not loosen during the fastening process, and ensuring the stability and reliability of the crimping.

[0073] Function of the limiting device 33: The limiting device 33 plays a crucial role in positioning and fixing the angle steel during the fastening process. The angle steel enters the fastening area through the receiving cylinders 331 on both sides of the limiting device 33. The receiving cylinders 331 penetrate the angle steel groove 332, and the rubber protective sleeve 333 connects the receiving cylinders 331 and the angle steel groove 332, effectively protecting the angle steel from scratches or wear during insertion and positioning. The operator can adjust the position of the angle steel positioning clamp by rotating the rotary button 334 on one side of the limiting device 33, thereby precisely adjusting the position of the angle steel to ensure that it is in the optimal position during the fastening process and improving the fastening quality.

[0074] Fifth, monitoring feedback and anomaly handling Real-time monitoring: The monitoring feedback subsystem 4 operates continuously throughout the entire operation, monitoring the system's operating status in real time. Temperature sensor 41 is installed inside capacitor 22, monitoring the temperature changes of capacitor 22 during charging and discharging in real time, and converting the temperature signal into an electrical signal which is transmitted to microcontroller 45. The operation panel 42 is located on the front side of the control panel 00, displaying various operating parameters of the system in real time, such as current, voltage, temperature, pulse intensity, and applied pressure, allowing operators to intuitively understand the system's operating status.

[0075] Anomaly Detection and Alarm: Alarm 43 is connected to current sensor 24, SCR power regulator 23, and temperature sensor 41. When current sensor 24 detects overcurrent, SCR power regulator 23 outputs overvoltage, or temperature sensor 41 detects overtemperature, alarm 43 will receive the corresponding signal and immediately issue a warning signal, such as an audible and visual alarm, to remind operators to take timely measures.

[0076] Temperature Compensation and Parameter Adjustment: The microcontroller 45 incorporates a temperature compensation algorithm. This algorithm is based on a pre-set mathematical model and combines real-time temperature data of the capacitor 22 collected by the temperature sensor 41. Since the electrical performance of the capacitor 22 changes with temperature—for example, as the temperature rises, the equivalent series resistance of the capacitor 22 increases, leading to increased energy loss during charging and affecting the charging current and voltage—the microcontroller 45 uses the temperature compensation algorithm to accurately calculate the parameter values ​​needed to maintain stable charging based on temperature fluctuations. The microcontroller 45 adjusts the voltage and current output by the power module 212 by changing the duty cycle of the PWM signal (Pulse Width Modulation signal). When the temperature rises, the microcontroller 45 appropriately reduces the duty cycle of the PWM signal based on the temperature compensation algorithm, reducing the charging current and preventing the capacitor 22 from being damaged by overheating; conversely, when the temperature decreases, the microcontroller 45 increases the duty cycle of the PWM signal, increasing the charging current and accelerating the charging speed.

[0077] Data Storage and Analysis: The microcontroller 45 interacts with the data memory 44 at high speed via the SPI interface. The microcontroller 45 promptly writes important data from the system operation process, such as operating temperature, voltage, current, and alarm records, into the data memory 44 for storage. The data memory 44 employs non-volatile storage technology (such as EEPROM and FLASH) to ensure that data is not lost due to power outages or other reasons. This stored data provides crucial information for system fault diagnosis, performance optimization, and operational status analysis. Operators can retrieve historical data from the data memory 44 during system operation or subsequent maintenance via the operation panel 42 or related software to analyze system operating trends, promptly identify potential problems, and take corresponding measures for optimization and troubleshooting.

[0078] Sixth, complete the tightening and equipment reset. Discharge Stop and Crimping Device 31 Reset: After the transmission tower angle steel is tightened, the charging control platform 2 will control the switching element 323 to disconnect, stopping the capacitor 22 from discharging to the electromagnetic pulse generation subsystem 3. The operator opens the locking mechanism 314 of the crimping device 31, opens the upper pressing mold 311 through the operating handle 313, and removes the tightened transmission tower angle steel from the crimping device 31.

[0079] Equipment movement or shutdown: If there are still other transmission tower angle steel sections that need to be tightened, the operator restarts the tracked subsystem 1 to move the equipment to the next work point and repeats the above workflow. Once the current operation is complete, the operator shuts down the system and turns off the power using the stop button on the control panel 42, and performs necessary cleaning and maintenance on the equipment to prepare for the next operation.
