[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings. It is obvious that the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments.

[0028] Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without making any creative work should fall within the scope of protection of the present invention.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Example 1

[0031] A wireless power supply system for lock identification and activation, characterized in that: it includes a wireless power supply device, a hull end and a lock end, the hull end includes a plurality of receiving devices, and the lock end includes a plurality of transmitting devices; the receiving device is installed on the equipment that needs to be powered, responsible for receiving electromagnetic energy and converting it into electric energy, and the transmitting device is installed on the shore of the lock and responsible for generating an electromagnetic field; the transmitting device includes a transmitting unit and a transmitting coil, the transmitting unit is used to convert the connected direct current power into alternating current power, and transmit the alternating current power to the receiving unit through the transmitting coil; the receiving device includes a receiving unit, including a receiving coil arranged in pair with the transmitting coil, and the receiving coil is used to receive alternating current power;

[0032] The wireless power supply device includes a power supply signal generating unit and a propagation coefficient calculating unit, wherein the power supply signal generating unit is used to generate a power supply signal; the propagation coefficient calculating unit is used to calculate the propagation coefficients of the wireless transceiver chips at the hull end and the lock end;

[0033] The lock end is provided with a reader for reading identification information on the vessel, and the hull end is provided with a tag / identification containing the identity information and data of the vessel;

[0034] Also included is a wireless power supply module, including a transmitting end and a receiving end, for transmitting electrical energy from the transmitting end to the receiving end;

[0035] An identification module, including a reader and an identification tag, for identifying the identity information of the vessel;

[0036] a control system, including a central controller and actuators, for processing identification information and controlling the operation of the locks;

[0037] Communication module, used for data transmission and coordination between various subsystems, including wired communication or wireless communication;

[0038] The opening or closing of the lock is automatically controlled according to the input information of the recognition system.

[0039] Specifically, when a ship with a tag comes to the lock, the reader will automatically identify the tag on the ship for pairing. After the pairing is successful, the wireless power supply device will start the power supply signal generation unit and the propagation coefficient calculation unit to calculate the propagation coefficients of the wireless transceiver chips at the hull end and the lock end. The first unit sends a power supply suspension instruction to the power transmitter; before the power transmitter suspends power supply, the first unit sends the operating status information and configuration information to the second unit; after the power transmitter resumes power supply, the second unit returns the operating status information and configuration information to the first unit; after receiving the returned operating status information and configuration information, the first unit works based on the operating status information and configuration information. The configuration information includes the timing duration of the power supply suspension, and the second unit includes a timing circuit, which is used to count the duration of the power supply suspension at the power transmitter. When the duration of the power supply suspension at the power transmitter exceeds the timing duration, the second unit sends an alarm message to the upper computer; when the upper computer receives the alarm message, it sends a reset signal to the second unit so that the second unit performs a reset operation.

[0040] The electromagnetic resonance circuit is driven to send a magnetic field energy signal, and a power receiving state signal fed back by the wireless power receiving device is obtained, and it is determined whether the power receiving state signal can be parsed out to obtain valid data. If valid data can be parsed out, the power receiving voltage and the power receiving current are parsed out; the load state of the wireless power receiving device is evaluated according to the power receiving voltage, and the evaluation process can be to determine whether the power supply voltage of the wireless power supply device is greater than the power receiving voltage. If the power supply voltage is greater than the power receiving voltage, it is considered that the load is overloaded and the output power is insufficient. If the power supply voltage is less than the power receiving voltage, it is considered that the load is underloaded and the output power is too high; when the load state is overloaded, the resonant frequency of the electromagnetic resonance circuit is lowered according to the size of the power receiving current to increase the transmission power of the magnetic field energy signal. The amplitude of the resonant frequency reduction can be calculated according to the size of the power receiving current, that is, the target value of the resonant frequency is calculated using the power receiving current. In the specific adjustment process, a step-by-step adjustment can be adopted to gradually make the resonant frequency approach the target value. In the case of underload, the resonant frequency of the electromagnetic latent vibration circuit is increased according to the magnitude of the receiving current, so as to reduce the transmission power of the peak magnetic field energy signal. The degree of harmonic frequency can be calculated according to the magnitude of the receiving current, that is, the target value of the resonant frequency is calculated by using the receiving current. In the specific adjustment process, a step-by-step adjustment can be adopted to gradually make the resonant frequency close to the target value. In the case that valid data cannot be parsed out, it is judged whether the power receiving state signal contains data features. The data features can refer to the fact that the power receiving state signal can be determined to be a signal that conforms to the law sent by the wireless power receiving device, but the valid data cannot be parsed out due to insufficient clarity; in the case that the power receiving state signal contains data to be queried, the possible reason is that the output power is insufficient, resulting in the unclear response of the wireless power receiving device, then the resonant frequency of the electromagnetic resonance circuit is reduced to increase the transmission power of the magnetic field energy signal. In the case that the power receiving state signal does not contain data features, it can be determined that the energy transmission fails or the wireless power receiving device fails, the number of energy transmission failures can be accumulated, and the power receiving state signal can be re-acquired. It is determined whether the accumulated times exceed the preset value. The wireless power receiving device is used in conjunction with the wireless power supply device, and its power receiving control program can execute a power receiving control method that cooperates with the control method of the wireless power supply device of this embodiment.The detection signal is obtained, and the detection signal is used to receive power, and the power receiving controller is initialized; a feedback signal in response to the detection signal is sent in a predetermined form; the wireless power supply device is detected to determine whether it has stably output electric energy, and the voltage value measured by the voltage measurement circuit of the power receiving end can be used for judgment. If the wireless power supply device does not stably output electric energy, the feedback signal in response to the detection signal is sent repeatedly in accordance with the predetermined form; if the wireless power supply device has stably output electric energy, that is, after determining that the electric energy can meet the requirements of the load supply, it enters the power receiving mode, turns on the circuit breaker protection circuit, and the voltage stabilization circuit starts to work; closes the load switch, and starts to supply power to the load. Detect the receiving voltage and the receiving current; determine whether the receiving voltage is abnormal, that is, determine whether the receiving voltage exceeds the set receiving voltage threshold range. If the receiving voltage is abnormal, interrupt the power supply to the load and wait for the wireless power supply device to return to normal; provide the wireless power supply device with a power receiving state signal, and wait for the wireless power supply device to adjust the output power. Through the cooperation of the above-mentioned wireless power receiving device and the wireless power supply device, the wireless power supply process can be completed efficiently together. Before wireless power supply, a detection signal is first sent, and the signal characteristics of the sensing signal received thereafter are used to identify the wireless power receiving device. Since the wireless power receiving device is confirmed by the time interval between the peaks in the anti-signal, the recognition efficiency is greatly improved, and the type of the wireless power receiving device can be further identified. Compared with the existing recognition process, the anti-interference ability is greatly improved, and the recognition efficiency and accuracy are also greatly improved. During the interval of sending the magnetic field energy signal, by detecting the attenuation of the attenuation section set in the attenuation signal, it is determined whether there is a foreign object in the magnetic field, thereby improving safety. The receiving device also includes a secondary converter connected to the power collector, which is used to adjust the high-frequency current output by the power collector to a stable third power supply to power the mobile device.

[0042] The second embodiment of the present invention is different from the previous embodiment. This embodiment provides a control method to solve the problem that the wireless power supply system can be further improved when in use.

[0046] The central controller issues a command to start the wireless power supply module, the transmitter starts to generate an electromagnetic field, and the receiver receives the electromagnetic energy and converts it into electrical energy to power the operating equipment of the lock.

[0047] The central controller issues instructions to control the actuator to open and close the lock gate; after the ship passes through the lock, the lock gate closes again, the central controller records the information of the ship passing through, and prepares for the next operation.

Once an abnormal situation is found, an alarm is immediately issued and corresponding measures are taken to prevent accidents.

[0049] The reader reads the RFID tag information on the ship and obtains the ship's identity information;

[0050] The central controller verifies the ship's identity information and decides whether to allow the ship to pass;

[0051] If the vessel is authorized to pass, the central controller activates the wireless power supply module, the transmitter generates an electromagnetic field, and the receiver receives electrical energy;
