[0018] Figure 4 It represents the change in magnetic flux density when the conduction current is 40A. Detailed Implementation

[0019] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] This embodiment provides a valve-structured wireless environmental energy harvesting and signal transmission device, fixed to the side surface of a heat sink, such as... Figure 1 As shown. It includes: a wireless energy harvesting coil, an energy storage capacitor, a power management circuit, a control chip, and a 5G signal transmission system, such as... Figure 2 As shown. The 5G signal transmission system includes: a modulator, a 5G baseband chip, a transmitter module, and a 5G module power supply unit, such as... Figure 3 As shown.

[0021] The wireless energy harvesting coil uses a polarized coil to convert electromagnetic wave power signals in the environment surrounding the valve structure into current energy through electromagnetic induction. This current energy is then transmitted to the power management circuit via wires. The power management circuit controls the absorbed electromagnetic wave power to meet the rated voltage requirements of the electrical equipment, thus powering the equipment. Excess energy is stored in an energy storage capacitor for use by other parts of the device.

[0022] The power management circuit processes the electromagnetic wave power signal and connects it to the control chip to supply power to the control chip. The control chip effectively identifies and calculates the received valve structure monitoring digital signal, and controls the control and feedback of each part. The control chip is connected to the modulator through the signal line and sends the valve structure monitoring digital signal to the modulator for processing.

[0023] The modulator converts the digital signal of valve structure monitoring into an analog energy signal and modulates the analog energy signal to be transmitted to meet the control requirements, which is beneficial for the 5G transmission module to process and transmit to the host computer.

[0024] The 5G baseband chip processes the modulated analog energy signal to be transmitted, converting it into a radio frequency signal suitable for transmission and transmission, and sends it to the 5G transmission module.

[0025] The 5G transmitter module sends radio frequency signals to the host computer. It is one of the core components of the 5G signal transmission system, completing the end-to-end communication function of sending data signals to the host computer.

[0026] The 5G module power supply unit receives energy from the power management circuit and energy storage capacitor, and then converts it through the power interface to power the 5G baseband chip, modulator and transmitter module.

[0027] When the IGCT valve structure is turned on and off, the sudden change in current causes a sudden change in the spatial magnetic flux density. According to Faraday's law of electromagnetic induction, the induced electromotive force is proportional to the rate of change of magnetic flux, which is also proportional to the rate of change of magnetic flux density. The wireless energy harvesting coil is wrapped around the IGCT device. When the IGCT is turned on and off, an induced electromotive force is generated in the coil, which in turn charges the power management circuit.

[0028] Powered by 380V 50HZ, the IGCT device conducts for 1ms in each cycle, with a conduction current of 40A. The magnetic induction intensity generated by the 40A conduction current is 190uT.

[0029] According to Faraday's law of electromagnetic induction, the induced electromotive force is proportional to the rate of change of magnetic flux, which is also proportional to the rate of change of magnetic induction intensity. Figure 4The magnetic flux density change is shown when the conduction current is 40A. The rate of change of magnetic flux density is large at the instants of conduction and turn-off, which is beneficial for energy harvesting.

[0030] Received energy: With a current of 40A and a transmitting coil diameter of 100mm, the received induced current is approximately 5mA. The larger the current, the greater the received energy. Similarly, with a current of 400A and a transmitting coil diameter of 100mm, the induced current is approximately 50mA; the transmitting coil can receive 40uJ per cycle.

[0031] Operating power consumption: The sampling time is approximately 2µs, and the power consumption is approximately 20µJ.

[0032] The energy received in each cycle is sufficient for one sampling.

[0033] Through testing and verification, the technical solution of this utility model, using a wireless environmental energy harvesting coil, can collect magnetic field energy in the environment surrounding the valve structure during normal switching operation and store it in an energy storage capacitor for use by the valve structure data detection system.

[0034] According to the embodiments of this utility model, the sensor is self-powered by harvesting electromagnetic energy in the environment. The sensor provides power for operation, which saves construction costs and also achieves high reliability, maintenance-free operation, long life and wide adaptability. This is of great significance for the construction of intelligent sensing systems for valve structures.
