[0026] Specifically, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first light-emitting laser lamp 5 turns off as the start bit, and then the laser lamp turns on and off according to the content of the data. 1 byte of 8-bit data is sent once, and the last bit of the 8-bit data is the parity bit. The parity bit verifies whether there is an error in the data transmission process. If odd parity is used, the number of lit bits in the data bit and the check bit is an odd number; if even parity is used, the number of lit bits is an even number. When the data content is sent, the first light-emitting laser lamp 5 of the host is lit, representing the stop bit, which means that the 1-byte content is sent. Then the second photosensitive photodiode 28 of the slave receiving module housing 26 detects the change of the laser lamp. Binary data transmission, according to the change of the high or low frequency of the clock crystal oscillator, determines the speed of data transmission. Reciprocating transmission can complete the data transmission. The slave transmitting module housing 18 can send information to the host receiving module housing 11 in the same way.

[0029] Working principle: When the utility model is in use, first, the electrical signal is converted into an optical signal. The host housing 1 serves as a signal transmitting source to send a communication signal to the slave housing 17. The first light-emitting laser lamp 5 inside the first cylindrical tube 3 on the side of the host transmitting module housing 2 emits laser light, and the first transparent convex lens 4 focuses the light to further increase the transmission distance of the laser light. When the data is started to be sent, the first light-emitting laser lamp 5 is turned off as the start bit, and then the on and off change of the laser lamp is determined according to the content of the data. 1 byte of 8-bit data is sent once, and the last bit of the 8-bit data is the parity bit. The parity bit verifies whether there is an error in the transmission process of the identification data. If odd parity is used, the number of lit bits in the data bits and the parity bits is an odd number; if even parity is used, the number of lit bits is an even number. When the data content is sent, the first light-emitting laser light 5 of the host lights up, representing the stop bit, which means that the sending of 1 byte of content is completed. Then the second photosensitive photodiode 28 of the slave receiving module shell 26 detects the changes in the brightness of the laser light for binary data transmission. The speed of data transmission is determined according to the changes in the high or low frequency of the clock crystal oscillator. The reciprocating cycle can complete the data transmission. The slave transmitting module shell 18 can send information to the host receiving module shell 11 in the same way. The inner walls of the second cylindrical tube 12 and the fourth cylindrical tube 27 are coated with a light-absorbing black coating to increase the accuracy of data communication.
