Embodiment Construction
[0024] refer to Figure 1-3 , a vehicle-mounted off-road mechanical exhaust emissions wireless transmission measurement method of the present invention, comprising the following steps:
[0025] The host computer 100 generates a command signal and sends the command data to the host 200 through the serial port, the processor of the host 200 sends the command data to the first radio frequency chip, and the first radio frequency chip transmits the command data to the first radio frequency chip after receiving the command data The internal FIFO module forms a ring signal wave to radiate the surrounding space through the antenna.
[0026] After the slave 300 receives the command from the host 200, the pin potential of the second radio frequency chip in the slave 300 decreases, and then reads the status register of the second radio frequency chip to determine whether the reception is interrupted. If the reception is interrupted, Then read the data sent by the host 200 from the FIFO ...
