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

Based on the wireless communications method of IEEE802-15-4 standard

Technical field:

The present invention relates to a kind of communication technology.

Background technology:

In the group activity that some member's spacing is shorter (as bicycle fleet), often need to link up timely each other, so that the communication of the information of carrying out and confirm mutual position, according to the mode of common intercom, shortcoming to carry out speech exchange, function is relatively single, and volume is large, and power consumption is higher.

Summary of the invention:

Goal of the invention of the present invention is the wireless communications method based on IEEE802-15-4 standard providing a kind of diverse in function, volume little, low in energy consumption.

The present invention realizes like this, comprise and form the telegon that of LAN has the wireless communication ability based on IEEE802-15-4 standard, the terminal of several wireless communication ability based on IEEE802-15-4 standard, telegon is provided with periodical timer, after terminal and telegon connect, a counter is set up to the terminal equipment connected, one-period timing terminates the rear counter corresponding to the terminal equipment of all connections and adds one, terminal sends heartbeat packet at set intervals to telegon, return connection status, telegon receives the counter O reset of correspondence after the heartbeat message of terminal, be cleared not yet when rolling counters forward reaches certain numerical value, show to be connected with terminal to lose, now coordinator unit verbal announcement helmet user immediately, reach the object connecting monitoring, user is by pushbutton enable wireless voice intercommunication, telegon directly can initiate speech talkback, other-end equipment then needs transmission request information to arrive telegon, telegon is replied and is confirmed that request just can initiate speech talkback.

Here, telegon, terminal are all connected with mobile phone by bluetooth module, can realize audio transmission, can realize dialing, receiving calls operation.

Telegon, terminal are all connected with mobile phone by bluetooth module, and mobile phone can use auxiliary App, obtain helmet operating state and change corresponding parameter, and in conjunction with the function of mobile phone, expand the function of this system.

Telegon, terminal all carry out transfer of data by bluetooth module and mobile phone, are responsible for carrying out data processing by the App on mobile phone.Mobile phone A pp can obtain working state of system, arranges system parameters, and passes through the function of this this system of App calling mobile phone Function Extension.

Telegon has voice call and interrupts function, and when needing, press-to-talk button sends the message of terminated speech intercommunication to all terminals, stops ongoing voice communication, then changes to and initiates speech talkback by telegon.

The present invention has the telegon of the wireless communication ability based on IEEE802-15-4 standard, the terminal of several wireless communication ability based on IEEE802-15-4 standard owing to adopting one of formation LAN, like this, can can not carry out that voice etc. are write to each other in team appointments too far away in bicycle team or team member's spacing, transmission information, confirm team member whether in team, and volume little, low in energy consumption, advantage that several functions can be expanded.

Accompanying drawing illustrates:

Fig. 1 is the flow chart that LAN of the present invention is set up;

Fig. 2 is the flow chart in LAN during voice call.

Embodiment:

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:

As shown in Figure 2, comprise and form the telegon that of LAN has the wireless communication ability based on IEEE802-15-4 standard, the terminal of several wireless communication ability based on IEEE802-15-4 standard, telegon is provided with periodical timer, after terminal and telegon connect, a counter is set up to the terminal equipment connected, one-period timing terminates the rear counter corresponding to the terminal equipment of all connections and adds one, terminal sends heartbeat packet at set intervals to telegon, return connection status, telegon receives the counter O reset of correspondence after the heartbeat message of terminal, be cleared not yet when rolling counters forward reaches certain numerical value, show to be connected with terminal to lose, now coordinator unit verbal announcement helmet user immediately, reach the object connecting monitoring, user is by pushbutton enable wireless voice intercommunication, telegon directly can initiate speech talkback, other-end equipment then needs transmission request information to arrive telegon, telegon is replied and is confirmed that request just can initiate speech talkback.

As shown in Figure 1, telegon, terminal is identical equipment, when LAN is set up, as the equipment of telegon to start as telegon or with undefined pattern random delay, and in start-up course scan for networks, when network not existing telegon, this device start is telegon, if when network existing telegon, to start unsuccessfully as the pattern of telegon, and inform user, undefined pattern startup is then connected on already present telegon with the pattern of terminal, other equipment restart with the pattern of terminal and in start-up course scan for networks, if when network existing telegon, be connected on telegon.

Telegon, terminal works situation notice informs user by text-to-speech mode.

Telegon, terminal use button as input control mode.

Telegon, terminal communication pattern are voice data communication mode, and the packet that this pattern sends does not need the other side's object equipment to reply, and cancels message retransmission mechanism.
