[0004] In the communication method of the prior art, there are the following defects:

[0005] 1. The signal level of the interface is relatively high: the logic level communication method uses a 3.3V TTL level communication signal. The signal level of the interface is relatively high, which is easy to damage the chip of the interface circuit. Because it is incompatible with the TTL level, a level conversion circuit is required to connect with the TTL circuit;

[0006] 2. Low transmission rate: In asynchronous transmission, the baud rate is 20Kbps; therefore, in the CPLD development board, the integrated program baud rate can only be 19200;

[0007] 3. Weak noise immunity: The interface uses a signal line and a signal return line to form a common ground transmission form, which is prone to common mode interference;

[0008] 4. Limited transmission distance: The standard value of the maximum transmission distance is 50 feet, and in practice it can only be used within about 15 meters.

[0009] In view of the above reasons, it is necessary to upgrade and transform the existing upper limb joint rehabilitation training system communication to overcome the above defects in the prior art. Summary of the invention

The single-chip microcomputer is also connected to an RS232 communication interface module, and the RS232 communication interface module is connected to a host computer through an RS232 and UBS conversion module, and a USB interface is provided on one side of the host computer;
