Abstract

The invention provides a slave unit access method in Bluetooth networking, a slave unit and a Bluetooth communication system. The method includes: the slave unit in the coverage of a master unit transmits a connectible broadcast message to the master unit during starting so as to allow the master unit to build connection with the slave unit according to the connectible broadcast message; the slave unit receives Bluetooth connection period configuration information, wherein the Bluetooth connection period configuration information is the Bluetooth connection period configuration information of the slave unit and is received by the master unit from a monitoring center after the master unit transmits the connection information to the monitoring center after the connection between the master unit and slave unit is built; the slave unit modifies the time period of connection period configuration according to the Bluetooth connection period configuration information and transmits a connectible broadcast message to the master unit at the interval of the time period so as to allow the master unit to build connection with the slave unit according to the connectible broadcast message. The method has the advantages that the defect that the few slave units can be simultaneously connected to low-power-consumption Bluetooth is overcome, the probability that the master unit needs to be connected with multiple slave units at the same time is lowered, the master unit can serve more slave units, energy can be saved, and low power consumption is achieved.

Description

In bluetooth group from equipment cut-in method, from equipment and Bluetooth communication system

Technical field

The present invention relates to short-distance wireless communication technology field, in more particularly, to a kind of bluetooth group From equipment cut-in method, from equipment and Bluetooth communication system.

Background technology

Bluetooth low energy consumption (bluetooth low energy, abbreviation ble) technology be low cost, Short distance, the wireless technology of interoperable, are operated in the 2.4ghz ism (industrial exempting to permit Scientific medical industry, science, medical science) radio frequency band.It designs from the beginning For super low-power consumption (ultra-low power, abbreviation ulp) wireless technology.It is using many intelligence Means can reduce power consumption to greatest extent, this technology can be used for the simple data between mini-plant Transmission is it is only necessary to one piece of button cell just can run 1 year.

Low-power consumption bluetooth solution is typically based on master/slave mechanism, that is, bluetooth master with Multiple Bluetooth slave devices are connected.One equipment can be bluetooth master or bluetooth from setting Standby, but it can not be bluetooth master and Bluetooth slave devices simultaneously.Bluetooth slave devices permit Permitted communication frequency by bluetooth master control, only in the case of bluetooth master requirement, bluetooth Just can communicate from equipment.In addition, low-power consumption bluetooth technology new features is exactly bluetooth From the broadcast capability of equipment, Bluetooth slave devices can announce by this approach that it has information to want Send bluetooth master to.Different according to type, broadcast is divided into: can connect and broadcast and non- Connect two kinds of broadcast, broadcast can be connected and allow other equipment to respond thereto and set up blue therewith Tooth connects, and disconnected broadcast then can ignore any response message and connection request.Can connect wide Broadcast and can only be sent by the bluetooth equipment being under disconnected state, and disconnected broadcast is then not limited System.

Bluetooth low energy consumption technologies adopt variable Connection Time interval, and this interval is according to concrete application Could be arranged to several milliseconds to several seconds.In addition, because ble technology is using very quick Connected mode, therefore may be at " disconnected " state (save energy), now link at ordinary times Two ends simply know other side each other, only just open link when necessary, then as far as possible Link is closed in the short time.Bluetooth low energy consumption technologies " completing " once connect and (scan it Its equipment, set up link, send data, certification and suitably terminate) only need 3ms.

The link layer of low-power consumption bluetooth has two states: Idle state and connected state.Main equipment uses The sweep parameter of its configuration is scanned, when scanning from the connected broadcast of equipment, meeting Send connection establishment request, be connected with setting up from equipment, now main equipment is even with from equipment Connect state.Main equipment can send with one party from equipment and disconnect request, connect after disconnecting, Main equipment be in idle condition from equipment.

At present, existing low-power consumption bluetooth technology is due to being limited by hardware processing capability, generally One main equipment can only be simultaneously connected with limited from equipment (being assumed to be n), that is, when certain a period of time Carve main equipment with n when equipment is set up and is connected and communicated, in main equipment coverage Other cannot use from equipment, and main equipment needs to service multiple scenes from equipment and can be limited System.

In consideration of it, how to overcome while saving more multi-energy low-power consumption bluetooth be simultaneously connected with from The less shortcoming of equipment number, making main equipment can serve more becoming from equipment needs at present Technical problem to be solved.

Content of the invention

For solving above-mentioned technical problem, the present invention provides in a kind of bluetooth group and accesses from equipment Method, from equipment and Bluetooth communication system, low-power consumption bluetooth can be overcome to be simultaneously connected with from equipment The less shortcoming of number, reducing main equipment needs to be simultaneously connected with multiple probabilities from equipment, makes master Equipment can be served more from equipment, saves more multi-energy, low in energy consumption.
