In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
In order to facilitate dynamic collection of the output torque of the motor, the embodiment of the present application provides a non-contact power supply and data transmission device 10, as shown in fig. 1. The contactless power supply and data transmission device 10 includes: a first wiring board 11 and a second wiring board 21.
The first circuit board 11 is provided with a data receiving circuit 13, a power module 12 and a first coil 14. The power supply module 12 is connected to the data receiving circuit 13 and the first coil 14, respectively, and the data receiving circuit 13 is connected to the first coil 14. The power module 12 is used for supplying power to the data receiving circuit 13 and the first coil 14. It should be noted that the power module 12 can output ac power and dc power at the same time, where the ac power is used for supplying power to the first coil 14, and the dc power is used for supplying power to the data receiving circuit 13. For example, the power module 12 includes an AC power source and a power supply circuit, the power supply circuit is configured to convert (e.g., rectify, filter, stabilize, etc.) the AC power generated by the AC power source into a dc power and then supply the dc power to the data receiving circuit 13, and the AC power generated by the AC power source is applied to the first coil 14 to supply power thereto. The power supply circuit may be a circuit commonly used at present for converting alternating current into direct current, which is well known to those skilled in the art and will not be described for avoiding redundancy. Of course, the power module 12 may also include a dc power source and an inverter circuit, and the inverter circuit is configured to invert the dc power output by the dc power source into ac power to supply the first coil 14. The inverter circuit may be a circuit commonly used at present to convert direct current into alternating current, which is well known to those skilled in the art and will not be described for avoiding redundancy.
The data receiving circuit 13 is used for acquiring the specified electric signals acquired and transmitted by the data acquisition and transmission circuit 24 on the second circuit board 21 through the first coil 14. For example, the data receiving circuit 13 is configured to obtain, via the first coil 14, an electric torque signal of the motor rotating shaft collected and transmitted by the data collecting and transmitting circuit 24 on the second circuit board 21. As an alternative embodiment, the data receiving circuit 13 is an NFC (Near Field Communication) card reader. The NFC card reader can realize point-to-point data communication, has no delay or almost negligible delay, and can greatly improve the efficiency of data exchange. Meanwhile, the working frequency band of the NFC is 13.56MHz, which is much smaller than that of other wireless digital communication technologies (such as bluetooth, WiFi, 3G, 4G, 5G, etc.), and the mutual interference between the working frequency band and the alternating current signal for supplying power to the first coil 14 is very small, which can be ignored with respect to other wireless digital communication technologies, so that the situation of poor integrity of transmitted data does not exist, and an integrity check link does not need to be added. It should be noted that, if the above other wireless digital communication technologies with the operating frequency band in the ultrahigh frequency band are used to transmit data, there is a certain delay in data transmission and processing, and meanwhile, the data transmission process is susceptible to interference, a calibration link needs to be added, filtering processing needs to be performed on incomplete frame data, and the data integrity is poor. Of course, the NFC card reader may be replaced by a Radio Frequency card reader with a Frequency band of 13.56MHz, that is, an RFID (Radio Frequency Identification) card reader.
It should be noted that, during the data transmission process, the first coil 14 corresponds to a receiving antenna of the data receiving circuit 13, and correspondingly, the second coil 22 corresponds to a transmitting antenna of the data collecting and transmitting circuit 24.
As another embodiment, in order to facilitate transmission of the specified electrical signal read by the NFC card reader, a first processor 15 is further disposed on the first circuit board 11, the first processor 15 is respectively connected to the power module 12 and the NFC card reader, and the first processor 15 is configured to transmit the specified electrical signal acquired by the NFC card reader, for example, to a main control board of the motor. The first Processor 15 may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; but also Digital Signal Processors (DSPs), Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs) or other Programmable logic devices, discrete Gate or transistor logic devices, discrete hardware components.

The power supply circuit 23 may be a circuit that converts alternating current into direct current, which is commonly used at present.
And the data acquisition and transmission circuit 24 is used for acquiring the specified electric signal of the preset target and transmitting the acquired specified electric signal to the second coil 22, so that the data receiving circuit 13 receives the specified electric signal coupled through the first coil 14. When the device is used, the second circuit board 21 is arranged opposite to the first circuit board 11, so that the first coil 14 is opposite to the second coil 22, and the electric energy acting on the first coil 14 can be coupled to the second coil 22 and converted into direct current to supply power to the data acquisition and transmission circuit 24 after being preprocessed (for example, rectified, filtered, stabilized and the like) by the power supply circuit 23. That is, according to faraday's law of electromagnetic induction, when an alternating current is applied to the first coil 14 (primary coil), a magnetic field is generated, and an alternating current is induced in the second coil 22 (secondary coil) due to the presence of an alternating magnetic field. During data transmission, a specific electrical signal acting on the second coil 22 can be coupled to the first coil 14 and read by the data receiving circuit 13. For example, when the noncontact power-supply and data-transmission device 10 is applied to a motor for detecting an output torque of the motor, the second wiring board 21 is provided on a shaft end of a rotation shaft of the motor to be rotatable with the rotation shaft, and the first wiring board 11 is provided on a housing opposite to the shaft end so that the first coil 14 is opposed to the second coil 22.

The collecting sensor 241 is configured to collect a specific electrical signal of a preset target, and transmit the collected specific electrical signal to the second processor 242. The acquisition sensor 241 may be flexibly set as required according to different signals to be acquired, for example, if the torque or the torque is acquired, the acquisition sensor 241 may be a torque sensor, a surface acoustic wave sensor, a torque sensor, or a bulk acoustic wave sensor.

A general purpose processor may be a microprocessor or the second processor 242 may be any conventional processor or the like.
The transmitter 243 is used to transmit the specified electric signal transmitted by the second processor 242 to the second coil 22. Alternatively, when the data receiving circuit 13 is an NFC reader, the transmitter 243 may be an NFC chip. And point-to-point communication is realized between the NFC card reader and the NFC chip. As another embodiment, the transmitter 243 may also be a dual port memory. The NFC interface of the dual port memory is connected to the second coil 22, and the other interface (which may be I) of the dual port memory2C interface) is connected to the second processor 242 to implement transmission and storage, so as to improve data transmission efficiency.

The amplifying circuit 244 is used to amplify the designated electrical signal and transmit the amplified signal to the second processor 242. The amplifier circuit 244 may be an operational amplifier circuit commonly used at present, which is well known to those skilled in the art and will not be described again to avoid redundancy.
The non-contact power supply and data transmission device 10 provided by the embodiment of the application well solves the problems of how to supply power to the sensor and how to transmit the data acquired by the sensor in special occasions (for example, acquiring the moment of a rotating shaft which continuously rotates), and in addition, the power supply and data transmission can be realized simultaneously only by adopting a group of coils, so that the structure is simple, and the process requirement is not high.
