Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor logistics automation, and in particular to a flat-plate power-taking contactless power supply system and method for RGV. Background Art

[0002] RGV stands for rail-guided vehicle. RGV can efficiently and accurately transport goods between different stations along the preset track, and can realize automatic storage and retrieval of goods. With the continuous advancement of science and technology and the widespread application of electronic equipment, higher requirements are placed on the convenience, safety and efficiency of power supply methods. Contactless power supply technology has emerged. It is based on the principles of electromagnetic induction and magnetic resonance, and realizes wireless transmission of electrical energy. The flat-panel design can better adapt to different installation and usage scenarios, providing more flexibility.

[0003] The existing flat-type contactless power supply is greatly affected by the environment. Metal obstacles and humid environments will interfere with the propagation and coupling of electromagnetic fields, thereby affecting the power supply effect. Relatively precise position alignment is required between the flat-type transmission and reception. When the position and alignment are inaccurate, abnormal situations will occur, which will seriously affect the power supply effect and the safety of the system. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a flat-plate power-collecting non-contact power supply system and method for RGV, aiming to improve the power supply effect and system stability under the influence of the environment and the position and misalignment.

[0006] The energy transmitting module is used to generate an alternating magnetic field and transmit energy to the external space;

[0007] The flat-plate power extraction module is used to induce electric energy in the alternating magnetic field;

[0008] The energy regulating module is connected to the flat-plate power taking module and is used to regulate and stably output the induced electric energy;

[0009] The control module is connected to the energy emission module and the energy regulation module respectively, and is used to control the parameters of energy emission and regulate the strategy of electric energy output;

[0010] The protection module is used to prevent abnormal conditions such as overvoltage, overcurrent and overheating from causing damage to the equipment, and ensure the safe and reliable operation of the system.

[0011] The energy transmitting module includes a power supply unit, a high-frequency inverter unit and a transmitting coil unit. The power supply unit is used to provide input power. The high-frequency inverter unit is connected to the power supply unit and is used to convert direct current into high-frequency alternating current. The transmitting coil unit is connected to the high-frequency inverter unit and is used to generate an alternating magnetic field according to the high-frequency alternating current.

[0012] The flat-plate power supply module includes a receiving coil unit, a rectifying and filtering unit and an energy storage unit.

[0014] The control module includes a sensor unit and a microprocessor unit. The sensor unit is used to monitor the working parameters of the system. The microprocessor unit and the sensor module unit are used to control energy emission and electric energy output according to monitoring data.

[0015] The protection module includes an overvoltage protection unit, an overcurrent protection unit, a short circuit protection unit, a temperature protection unit, a leakage protection unit and a surge protection unit. The overvoltage protection unit is used to monitor the output voltage and quickly cut off the circuit. The overcurrent protection unit is used to detect the current in the circuit in real time. The short circuit protection unit is used to quickly detect a short circuit fault in the circuit. The temperature protection unit is used to monitor the temperature in the system. The leakage protection unit is used to detect whether there is leakage in the system. The surge protection unit is used to suppress sudden high voltage surges in the circuit.

[0016] In a second aspect, the present invention provides the following technical solution, a flat-plate type non-contact power supply method for RGV, the method comprising:

[0017] Step 1: The power supply unit in the energy transmitting module provides a stable direct current input, the high-frequency inverter unit converts the direct current into high-frequency alternating current, the transmitting coil module generates an alternating magnetic field of a specific frequency and intensity according to the high-frequency alternating current, and transmits energy to the external space in a specific direction and range;

[0018] Step 2: The receiving coil unit in the flat-type power taking module is in the alternating magnetic field, and generates an induced electromotive force through the principle of electromagnetic induction. The induced electromotive force is rectified and filtered by the rectifying and filtering unit, and converted into a relatively smooth direct current, which is then stored in the energy storage unit;

[0020] Step 4: With the help of the sensor module in the control module, the working parameters of the system are continuously monitored. The microprocessor unit calculates and analyzes the working status of the system according to the data collected by the sensor unit, and then controls the working frequency and duty cycle of the high-frequency inverter unit of the energy transmitting unit, adjusts the intensity and frequency of the alternating magnetic field generated by the transmitting coil module, and adjusts the power regulation and voltage stabilization strategy of the energy regulating unit, so as to achieve precise control of the parameters of energy transmission and the output of electric energy;

[0021] Step 5: When powering the system, the protection module uses sensors to monitor the system's voltage, current, power, temperature, leakage and surge in real time.

[0022] Preferably, in step five, the voltage, current, power, temperature, leakage and surge are respectively measured using a current sensor, a temperature sensor, a leakage sensor, an electromagnetic sensor and a power sensor.

[0025] The present invention has the following beneficial effects:

[0026] 1. In the present invention, real-time dynamic compensation is performed through the energy regulation module, which can monitor the impact of environmental changes on energy transmission in real time, and perform dynamic compensation adjustment to maintain the stability of output energy. In addition, electromagnetic shielding is enhanced through electromagnetic sensors to reduce the interference of external electromagnetic fields on the internal system, and further reduce the interference of metal obstacles and humid environmental factors on electromagnetic field propagation and coupling, thereby improving the effect and stability of flat-type power supply and non-contact power supply.

[0027] 2. In the present invention, the energy regulation module cooperates with the protection module, so that when the transmitting coil unit and the receiving coil unit are not aligned, the energy regulation module performs energy regulation, so that only weak and slow power supply can be carried out between the two, and continued alignment work is required to carry out efficient power supply. The system is monitored in real time through the protection module to avoid long-term power supply under misalignment, which may affect the power supply effect and system safety.
