[0024] A non-contact connector plug and a non-contact connector socket are provided. The non-contact connector plug integrates a data signal transmitting circuit module, and the non-contact connector socket integrates a data signal receiving circuit module. The data signal transmitting circuit module and the data signal receiving circuit module work together to realize the wireless data signal transmission function between the plug and the socket.

[0025] The data signal transmitting circuit module includes a first controller MCU, and a first power supply module, a first host computer communication module, and a wireless transmitting module communicatively connected to the first controller MCU. The first power supply module is used to supply power to the wireless transmitting module and the first controller MCU after voltage conversion.

The second power supply module is used to supply power to the wireless receiving module and the second controller MCU after voltage conversion. The second host computer communication module is used to enable the second controller MCU to communicate with a host computer for data communication. The wireless receiving module is used to receive wireless signals.

[0026] This invention provides a circuit design for a contactless connection system capable of transmitting data signals. The circuit module is small in size and easily integrated into existing connectors. This provides a technical foundation for future product upgrades and circuit improvements. Furthermore, this system circuit achieves point-to-point character data communication within a 10m range, with stable signal transmission and extremely high reliability.

[0027] In this embodiment, the wireless transmitting and receiving modules are developed using domestically produced 2.4GHz wireless modules. These modules utilize the SPI communication protocol and are functionally designed using a microcontroller. Specifically, the Si24R1 wireless communication module is used, and its schematic diagram is shown below. Figure 3As shown, the wireless communication module brings out the SPI communication interface and power interface for communication with the controller MCU microcontroller.

[0028] The controller MCU circuit described in this embodiment is as follows: Figure 4 As shown, the circuit includes a microcontroller reset button circuit, a crystal oscillator circuit, and an interface connected to the wireless transceiver circuit, and also establishes an interface connection for serial communication with the host computer. In this embodiment, the preferred controller MCU chip is the STC89C52.

[0029] In this embodiment, both the first controller MCU and the second controller MCU are connected to the host computer via serial communication interfaces. This allows for observation of communication data on the host computer, including real-time monitoring of the data transmission process, issuing control commands through the host computer, and transmitting custom data. The host computer in this embodiment is a computer capable of directly issuing control commands, as is common in the prior art.

[0030] The circuit of the power module described above in this embodiment is as follows: Figure 5 As shown, the power module realizes the function of converting 5V to 3.3V to power the wireless communication module and the microcontroller (the first controller MCU and the second controller MCU mentioned above), and can also share the power interface with the serial communication interface.

[0031] In one embodiment, the data signal transmitting circuit module further includes a first button module communicatively connected to the first controller MCU; the data signal receiving circuit module further includes a second button module communicatively connected to the second controller MCU. Both the first button module and the second button module are used to switch between wireless data communication modes to control the data transmission process. The circuit of the button module is as follows: Figure 6 As shown, the functions of sending fixed strings and sending custom strings are implemented through software programming.

[0032] In this embodiment, the principle of the aforementioned button module is as follows: each button is a normally open switch circuit. When a designated function key or number key is pressed, it is in a closed state. For a group of keys or a keyboard, it needs to be connected to a microcontroller through an interface circuit to notify the microcontroller of the key's on / off state. The microcontroller can use polling or interrupt methods to determine if there is a key input and check which key is pressed. It then uses a transfer instruction to execute the function program for that key, and returns to the original state after execution. This button module achieves communication mode switching through this button method.

[0033] In one embodiment, the data signal transmitting circuit module further includes a first display module communicatively connected to the first controller MCU; the data signal receiving circuit module further includes a second display module communicatively connected to the second controller MCU. Both the first and second display modules are used to implement LED flashing display during the communication process. When the signal transmitting module and signal receiving module are transmitting signals normally, the LEDs in the display module flash normally to verify and determine the normal progress of wireless communication transmission. The display module circuit is as follows: Figure 7 As shown.

[0034] In this embodiment, the preferred circuit board structure is such that the dimensions of the data signal transmitting circuit module and the data signal receiving circuit module are approximately 45mm*25mm*10mm (length*width*height), which is relatively small and convenient for installation.

[0035] The wireless contactless connection system circuit module in this embodiment of the invention achieves high transmission efficiency and realizes the goal of effective data transmission in the contactless connection system. The overall circuit size is small, making it easy to integrate into existing connectors, and provides technical reserves for future product upgrades and circuit improvements.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
