Description
Technical Field
The present invention relates to the field of data transmission technologies, and in particular, to a Zigbee data transmission method, a Zigbee data transmission system, and a Zigbee data transmission device.
Background
Zigbee transmissions support an acknowledgement mechanism, which is generally turned on by default for the reliability of the transmission. For example, the sub-device switch is taken as an example, (1) the gateway command is issued, such as an on command; (2) the gateway waits for the ACK return of the sub-equipment; (3) if the kid device does not return an ACK, the gateway will retransmit. This ensures the reliability of the gateway commands reaching the kid device. The processing flow of the sub-equipment is as follows: (1) the sub-device reports the current device state, such as the on state, after receiving the on command of the gateway and completing the executed action. (2) The gateway receives the state report of the equipment and returns an ACK message; (3) the sub-equipment will detect whether there is ACK message returned, and if there is no ACK message returned, the state is reported again. Therefore, the reliability of the state reporting of the sub-equipment is ensured. The detailed schematic is shown in figure 1.
Although the method can ensure reliable transmission of data to the maximum extent, when the data of the sub-equipment is more, the situation of data loss is easy to occur due to more interaction, so that a large amount of retransmission and ACK confirmation messages are generated, and transmission is further deteriorated.
