Automatic allocation method for serial device communication addresses

The invention relates to an automatic allocation method for serial device communication addresses, which comprises the following steps: after an instruction is received from a device, setting an address recognition output pin to be high or low, and judging whether the levels of the output pin and an input pin are consistent or not; and if the levels of the input pin and the output pin are inconsistent, setting the own equipment address to be 1, sending the equipment address to the gateway, and outputting two pulses to the next equipment at the output pin after delaying for a period of time; ifthe level of the output pin is consistent with the level of the input pin, enabling the slave equipment to configure the address recognition input pin to be in an edge or level triggering interrupt mode; accumulating the number of the pulses in the interruption, setting the number of the pulses as the address of the device itself after the number of the pulses is transmitted, sending the addressto the gateway, and then adding one pulse to the number of the addresses output by the address recognition output pin to the next device. Therefore, the method for automatically allocating the addresses of the gateway and the following slave devices in the serial port mode is realized, and the flexibility and convenience of allocating the addresses of the plurality of slave devices are improved.
