The invention discloses a single-line communication method. The method comprises the following steps that: when master equipment and slave equipment do not carry out data communication, the master equipment sends first verification data to the slave equipment, and the slave equipment returns second verification data to the master equipment after receiving the first verification data; after starting data communication, the master equipment waits for second verification data returned by the slave equipment and sends master communication data to the slave equipment after receiving the second verification data, and the master equipment and the slave equipment enter data communication; and after starting data communication, the slave equipment waits for the first verification data sent by the master equipment and sends the slave communication data to the master equipment after receiving the first verification data, and the master equipment and the slave equipment enter data communication. Visibly, the single-line communication method prevents the master equipment and the slave equipment from entering the sending mode at the same time, thereby preventing data transmission congestion andimproving the communication stability. The invention further discloses a single-wire communication system which has the same beneficial effects as the single-wire communication method.
Description
technical field [0001] The invention relates to the field of data communication, in particular to a single-line communication method and system. Background technique [0002] When designing the structure of smart wearable devices, miniaturization is one of the main design requirements. At present, in order to simplify the equipment structure, the technical means usually adopted is: multiplex the communication contact for sending data and the communication contact for receiving data to the same communication contact, that is, the same communication channel is used for sending and receiving, and That is, the smart wearable device communicates with the external device through a single line. However, the single-line communication has the following problems: if the smart wearable device and the external device transmit data to each other at the same time, the two will enter the sending mode at the same time, resulting in the blockage of data transmission on the single transmissi...
