A wireless communication method based on the IEEE802-15-4 standard

Abstract

The invention provides a wireless communication method based on the IEEE802-15-4 standard. The method requires a coordinator having the wireless communication capability based on the IEEE802-15-4 standard and a plurality of terminals having the wireless communication capability based on the IEEE802-15-4 standard, the coordinator and the terminals forming a local area network. The coordinator is provided with a periodic timer. After connection is established between the terminals and the coordinator, a counter is established for each terminal device in connection; after the timing of a period is over, one is added to the counters corresponding to all the terminal devices in connection; each terminal sends a heartbeat packet to the coordinator at intervals to report the connection state; users start wireless voice talkback through buttons and the coordinator can directly initiate voice talkback; other terminal devices need to send request information to the coordinator and cannot initiate voice talkback until the coordinator replies to and confirms the requests. Compared with the conventional methods, the method has the advantages of multiple functions, small size and low power consumption.

Description

Technical field: [0001] The invention relates to a communication technology. Background technique: [0002] In some group activities with short distances between members (such as bicycle convoys), timely communication is often required to communicate information and confirm each other's positions. If the usual walkie-talkie method is used, the disadvantage is that it can only For voice communication, the function is relatively single, and the volume is large, and the power consumption is high. Invention content: [0003] The object of the present invention is to provide a wireless communication method based on the IEEE802-15-4 standard with various functions, small size and low power consumption. [0004] The present invention is achieved in this way, including a coordinator with wireless communication capability based on the IEEE802-15-4 standard and several terminals with wireless communication capabilities based on the IEEE802-15-4 standard constituting a local area ne...
