The data transmission between the rangefinder and the upper computer includes the following:
Control commands: including start distance measurement, continuous distance measurement, single distance measurement, query commands, etc.
Return data: including distance information, ambient temperature, rangefinder status, etc. The data exchange between the rangefinder and the upper computer adopts the 422 bus. The specific software communication protocol is as follows:
Communication format: RS422 communication, baud rate 115200bps;
Data format: 8-bit data, one start bit, one stop bit, without parity check. The data consists of a header byte, command part, data length, parameter part, and checksum byte;.
Communication method: The master control and rangefinder adopt a master-slave communication method. The master control sends control commands to the rangefinder, and the rangefinder receives and executes the commands. In the ranging state, the rangefinder sends back the data and status of the rangefinder to the upper computer according to the ranging cycle. The communication format and command content are shown in the table below.
