[0003] However, the power supply method of directly powering electrical equipment with the acquired electromagnetic induced electromotive force or through an energy storage unit does not set the output power according to the type and number of electrical equipment, and does not reasonably allocate the output power according to the current power demand of the electrical equipment, which inevitably causes fluctuations in the power supply voltage of the electrical equipment and causes energy waste.

[0009] The current output power of the isolation transformer unit is adaptively adjusted and controlled as follows: If the current output power of the isolation transformer unit is less than the current power demand range of the electrical equipment, the output voltage and output current of the energy storage unit are adaptively adjusted to increase, thereby controlling the output power of the isolation transformer unit to meet the current power demand conditions of the electrical equipment; If the current output power of the isolation transformer unit is greater than or equal to the current power demand range of the electrical equipment, the output voltage and output current of the energy storage unit are adaptively adjusted to reduce the output power of the isolation transformer unit, thereby controlling the output power of the isolation transformer unit to meet the current power demand conditions of the electrical equipment.

[0010] Each transformer unit in the multi-channel transformer unit is connected to one or more electrical devices to supply power thereto.

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 is a flow chart of the method of the present invention; Figure 2 Schematic diagram of the system structure of the present invention in one embodiment. DETAILED DESCRIPTION

[0020] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0021] Example 1 This embodiment provides an energy management adaptive power supply method for power transmission line induction energy extraction, such as Figure 1 As shown, the following steps are included: S101. Generate a duty cycle adjustment control signal based on an input voltage and an input current of a power supply unit of a power transmission line to control an isolation transformer unit to provide a stable power output.

[0022] The transmission line energy acquisition unit is installed on the transmission line to obtain electromagnetic induced electromotive force. The transmission line energy acquisition unit is used to charge the energy storage unit and supply power to the electrical equipment. The input voltage and input current of the transmission line energy acquisition unit are obtained, and a reference value comparison process is performed based on the input voltage and input current of the transmission line energy acquisition unit and the set reference value. The reference value comparison process includes a voltage reference value comparison process and a current reference value comparison process. Based on the reference value comparison process result, the duty cycle is adjusted to control the output voltage and output current of the isolation transformer unit.

[0023] Specifically, the following steps are included: Comparing the input voltage of the power transmission line energy taking unit with the set voltage reference value; Comparing the input current of the power transmission line energy taking unit with the set current reference value; generating a duty cycle adjustment control signal based on a voltage reference value comparison processing result and a current reference value comparison processing result; The output voltage and output current of the energy storage unit are adaptively adjusted based on the duty cycle adjustment control signal, and the output voltage and output current of the isolation transformer unit are controlled by the energy storage unit to output stable power.

[0024] For example, in Figure 2In the system shown, the first controller unit obtains the input voltage and input current of the power transmission line energy acquisition unit, and compares the input voltage and input current of the power transmission line energy acquisition unit with the set reference value. If the input voltage and input current of the power transmission line energy acquisition unit are both less than the set voltage reference value and the set current reference value, the energy storage unit is controlled to supply power and generate a duty cycle adjustment control signal to be transmitted to the isolation driver unit, and the output voltage and output current of the energy storage unit are adaptively adjusted based on the duty cycle adjustment control signal, thereby controlling the output voltage and output current of the isolation transformer unit. By controlling the output voltage and output current of the isolation transformer unit, the power demand conditions of the electrical equipment can be met.

[0025] S102, based on the detection signal of the electric device, determine the current power demand range of the electric device, and compare the power demand with the current output power of the isolation transformer unit, adjust the output power of the isolation transformer unit according to the comparison result to match the power demand of the electric device, and after the adjustment is completed, call the electric device commissioning log to generate an output power allocation control signal.

[0026] In this embodiment, the electric device detection signal includes an electric device quantity detection signal and an electric device type detection signal.

[0027] For example, the types of electrical equipment include current acquisition units, voltage acquisition units, image acquisition units, communication transmission units, temperature acquisition units, humidity acquisition units, etc. Electrical equipment is divided into types of electrical equipment according to power size, and the types of electrical equipment include primary power equipment type, secondary power equipment type, and tertiary power equipment type. The types of electrical equipment can be divided according to specific actual usage conditions, and are not specifically limited in this application.

[0028] In order to further meet the power demand of multiple electrical devices at the same time, the output power of the isolation transformer unit is controlled based on the detection signal of the electrical device to meet the power demand conditions of the electrical device. For example, the detection signal of the electrical device is obtained, the number and type of the electrical devices are determined based on the detection signal of the electrical device, and the power demand of the electrical devices is determined by the number and type of the electrical devices. Based on the input voltage and input current of the transmission line energy acquisition unit, it is determined whether the current power demand of the electrical device is met. If the current power demand of the electrical device cannot be met, the output voltage and output current of the energy storage unit are adaptively adjusted to control the output power of the isolation transformer unit so that the output power of the isolation transformer unit meets the current power demand conditions of the electrical device.

[0029] Specifically, the following steps are included: Determine the current power demand range of the electric device based on the electric device quantity detection signal and the electric device type detection signal; Compare the current output power of the isolation transformer unit with the current power demand range of the electrical equipment, and adaptively adjust and control the current output power of the isolation transformer unit to ensure that the output power of the isolation transformer unit meets the current power demand conditions of the electrical equipment; Call the power equipment commissioning log to obtain the power equipment commissioning signal; An output power distribution control signal is generated based on the power-consuming device quantity detection signal, the power-consuming device type detection signal and the power-consuming device commissioning signal.

[0030] The current output power of the isolation transformer unit is adaptively adjusted and controlled as follows: If the current output power of the isolation transformer unit is less than the current power demand range of the electrical equipment, the output voltage and output current of the energy storage unit are adaptively adjusted to increase, thereby controlling the output power of the isolation transformer unit to meet the current power demand conditions of the electrical equipment; If the current output power of the isolation transformer unit is greater than or equal to the current power demand range of the electrical equipment, the output voltage and output current of the energy storage unit are adaptively adjusted to reduce the output power of the isolation transformer unit, thereby controlling the output power of the isolation transformer unit to meet the current power demand conditions of the electrical equipment.

[0031] For example, in Figure 2 In the system shown, the second controller unit obtains the output voltage and output current of the isolation transformer unit. The current output power of the isolation transformer unit is determined based on the output voltage and output current of the isolation transformer unit, and the type and number of electrical equipment currently in use are determined by obtaining the electrical equipment detection signal. The current power demand condition is determined based on the type and number of electrical equipment currently in use, and it is determined whether the current output power of the isolation transformer unit meets the current power demand condition of the electrical equipment. The current output power of the isolation transformer unit is adaptively adjusted to ensure that the output power of the isolation transformer unit meets the current power demand condition of the electrical equipment. The signal for the electrical equipment to be put into use can be obtained by calling the electrical equipment put into use log.

[0032] Based on the power equipment commissioning signal, the corresponding power equipment is controlled to be commissioned. The power equipment commissioning signal includes the power equipment commissioning type, the power equipment commissioning quantity and the power equipment commissioning duration. The output power allocation control signal is generated based on the power equipment quantity detection signal, the power equipment type detection signal and the power equipment commissioning signal, wherein the power equipment commissioning duration is used to determine the timeliness of the output power allocation control signal. For example, if the power equipment commissioning duration is 1 hour, the timeliness of the output power allocation control signal is 1 hour. The power supply to the power equipment is stopped after 1 hour of commissioning, and the power equipment commissioning signal needs to be obtained to re-power the power equipment.

[0033] S103, distributing power to the multi-channel transformer unit based on the output power distribution control signal and the power-consuming device detection signal, and controlling the output voltage of the multi-channel transformer unit.

[0034] The multi-channel transformer unit includes 2 or more transformer units. This embodiment takes the case where 2 transformer units of the multi-channel transformer unit are working at the same time as an example. The first transformer unit is used to provide a regulated output to the first electrical device, and the second transformer unit is used to provide a regulated output to the second electrical device (other electrical devices and other transformers are not put into use). The first transformer unit and the second transformer unit can be a DC-to-DC boost module or a DC-to-DC buck module. In this embodiment, the first transformer unit and the second transformer unit are not specifically limited. The first transformer unit and the second transformer unit can be used for boosting or bucking according to actual usage.

[0035] Specifically, the following steps are included: Determine the current power demand of the electric equipment corresponding to each transformer unit of the multiple transformer units based on the electric equipment detection signal; Based on the current power demand of the power-consuming equipment, the power demand is matched between the multi-channel transformer units and the output power distribution control signal; The output voltage of the multi-channel transformer unit is controlled based on the allocated output power distribution control signal.

[0036] The output power allocation control signal is divided into different levels according to the output power size, and the output power allocation control signal of the corresponding level is matched according to the current power demand of the power-consuming equipment to control the transformer unit of the corresponding circuit of the power-consuming equipment.

[0037] In this embodiment, power distribution processing is performed on a multi-channel transformer unit based on an output power distribution control signal and an electrical equipment detection signal, and the output power distribution control signal includes a first-level output power range distribution control signal, a second-level output power range distribution control signal, and a third-level output power range distribution control signal. It should be noted that the output power of the third-level output power range distribution control signal is higher than the output power of the second-level output power range distribution control signal, and the output power of the second-level output power range distribution control signal is higher than the output power of the first-level output power range distribution control signal. The output power range can be set according to actual usage, and simply increasing or decreasing the number of levels of the output power range distribution control signal falls within the protection scope of this application.

[0038] For example, in Figure 2 In the system shown, the output power distribution control signal is transmitted to the driver unit, and the output power of the first transformer unit and the second transformer is controlled based on the output power distribution control signal and the power equipment detection signal. The type and quantity of the power equipment connected to the first transformer unit are determined by the power equipment detection signal, so as to select the output power range distribution control signal that meets the current power demand condition from the first, second and third level output power range distribution control signals. For example, the power equipment connected to the first transformer unit is a first-level power power equipment type, and the first transformer unit is allocated a first-level output power range distribution control signal to meet the current power demand condition of the power equipment, and the output voltage of the first transformer unit is controlled based on the first-level output power range distribution control signal; the power equipment connected to the second transformer unit is a third-level power power equipment type, and the second transformer unit is allocated a third-level output power range distribution control signal to meet the current power demand condition of the power equipment, and the output voltage of the second transformer unit is controlled based on the third-level output power range distribution control signal. By performing power distribution processing on multiple transformer units based on the output power distribution control signal and the power equipment detection signal, the utilization rate of energy is greatly improved and unnecessary energy consumption is reduced.

[0039] S104, performing multi-stage ramp compensation processing based on the output voltage of the multi-channel transformer unit to provide a stable voltage output for the electrical equipment to adapt itself.

[0040] By performing multi-stage ramp compensation on the output voltage of multiple transformer units, the fluctuation of the output voltage can be reduced, thereby adaptively providing a stable voltage output for the electrical equipment. For example, the output voltage of the first transformer unit and the second transformer unit is obtained, and the voltage is compared with the voltage setting value, and a multi-channel duty cycle adjustment control signal is generated based on the voltage comparison result to adjust and control the output voltage of the first transformer unit and the second transformer unit respectively, so as to adaptively provide a regulated voltage output for the electrical equipment connected to the first transformer unit and the second transformer unit.

[0041] Specifically, the following steps are included: Obtain output voltage signals of multiple transformer units and compare the voltages with the voltage setting values; Based on the voltage comparison results, multiple duty cycle adjustment control signals are generated. According to the comparison results of the multiple duty cycle adjustment control signals with the preset multiple duty cycle levels, it is determined whether to perform ramp compensation and the size of the ramp compensation to be performed, so as to adjust the output voltage size of the multiple transformer units and provide a regulated output for the electrical equipment.

[0042] Wherein, when the duty cycle is less than the first set duty cycle value, no ramp compensation is performed; When the duty cycle is greater than or equal to the first set duty cycle value and less than the second set duty cycle value, first-level ramp compensation is performed; When the duty cycle is greater than or equal to the second set duty cycle value and less than the third set duty cycle value, secondary ramp compensation is performed.

[0043] For example, when the duty cycle is less than 30%, no ramp compensation is performed; when the duty cycle is greater than or equal to 30% and less than 45%, first-level ramp compensation is performed; when the duty cycle is greater than or equal to 45% and less than 55%, second-level ramp compensation is performed. The duty cycle value and the number of segments of the multi-stage ramp compensation can be set according to the specific actual use situation, and are not specifically limited in this application. The multi-stage ramp compensation processing of the output voltage of the multi-channel transformer unit falls within the protection scope of this application. By performing multi-stage ramp compensation processing on the output voltage of the multi-channel transformer unit, a stable voltage output can be provided for the electrical equipment.
