State packet etc. duration to be sent.
Wherein, in the equipment state packet of slave devices the slave devices device type, device identification and status information.
Optionally, online slave devices often receive a synchronous package, and next equipment state packet is sent according only to the synchronous package.
This step can be realized by several steps as shown in Figure 4：
Step 410, online equipment queue table is obtained from the synchronous package.
After executing step 410, step 420 and/or step 430 can perform.
Step 420, if the online equipment queue table includes the device type of itself, in the online equipment queue table
In the case of including the device identification of itself, according to from online equipment list queue number, host equipment is online
The durations to be sent such as the queue number determination in list of devices.
For example, calculated using a formula the next equipment state packet of itself etc. duration to be sent, the formula be：
T1=(Q2-a)×T0；
Wherein, T1For next equipment state packet etc. duration to be sent, Q2It is the slave devices in online equipment list
Queue number, T0For delay time parameter, a is queue number of the host equipment in online equipment list.For example, host is set
The standby queue number in online equipment list is 0, then the value of a is 0；For another example machine equipment is in online equipment list
Queue number is 1, then the value of a is 1.Delay time parameter can be the parameter of systemic presupposition, or customized ginseng
Number.For example, T0For preset 5ms.

For example, in their the online equipment queue tables in the synchronous package that pedestal socket is sent；The queue number of pedestal insert row is
0, the queue number of LED light is 1, the queue number of Baffle Box of Bluetooth is 2, the queue number of wireless charging is 3.Then LED light is receiving
A delay time parameter is waited for retransmit its equipment state packet to when synchronous package.
It should be noted that above-mentioned formula only by queue number and is shaken hands for sequence correlation, optionally,
For negative correlativing relation when, above-mentioned formula can be T with mutation1=(a-Q2)×T0；
Step 430, if the online equipment queue table includes the device type of itself, in the online equipment queue table packet
In the case of the device identification for including itself, in the equipment state packet for receiving other slave devices, set according to other slaves
Standby and certainly in the online equipment list queue number determines such duration to be sent.
In line slave devices after receiving synchronous package, these online slave devices are according to from online equipment list
Queue number priority sending device state packet.Implementing to be：Any slave devices are receiving other slave devices
Equipment state packet when, it is true according to the queue number of other slave devices and the slave devices in the online equipment list
Fixed such duration to be sent.
For example, calculated using the first formula the next equipment state packet of itself etc. duration to be sent, the first formula be：
T1=(Q2-Q1-a)×T0；
Wherein, T1For next equipment state packet etc. duration to be sent, Q2For the queue certainly in online equipment list
Number, Q1For the queue number of other slave devices in online equipment list, T0For delay time parameter, a is host equipment
Queue number in online equipment list.
For example, include Baffle Box of Bluetooth, LED light, wireless charging by pedestal socket, online slave devices of host equipment
For example, in their the online equipment queue tables in the synchronous package that pedestal socket is sent；The queue number of pedestal insert row is
0, the queue number of LED light is 1, the queue number of Baffle Box of Bluetooth is 2, the queue number of wireless charging is 3.
Using slave devices as bluetooth equipment for example, bluetooth equipment knows the queue of oneself after receiving synchronous package
Number is 2, current when itself receiving the equipment state packet of LED light, calculate next equipment state packet of bluetooth equipment etc.
Time to be sent is (2-0-1) * T0, then bluetooth equipment wait for a time parameter T0The equipment state packet of itself is retransmited afterwards.
Step 330, according to the online slave quantity of the host equipment determine next equipment state packet etc. it is to be sent when
It is long.
The realization of this step can be：Online equipment queue table is obtained from the synchronous package；If the online equipment queue table
Do not include the device type of itself, then determines the total quantity of online slave and host equipment according to the online equipment list；Root
Any of priority and total quantity determination etc. are corresponded to according to the corresponding number of equipment of itself type, equipment of itself type
Duration to be sent.
Wherein, determine that the realization of the total quantity of online slave and host equipment can be according to the online equipment list：
In the case where the queue number of host equipment is 1, obtains the maximum queue number of numerical value in the online equipment list and obtain
The total quantity of line slave and host equipment；In the case where the queue number of host equipment is 0, obtain in the online equipment list
The maximum queue number of numerical value adds 1 to obtain the total quantity of online slave and host equipment.
Wherein, determine etc. that the realization of duration to be sent can be with according to the total quantity, the corresponding number of device type of itself
For：The summed result for calculating total quantity number corresponding with the device type of itself, when being multiplied by delay using the summed result
Between parameter the duration to be sent such as obtain.Wherein, delay time parameter is usually set by system developer.Not online slave is set to set
It is standby to be retransmited after line slave devices sending device state packet all, and all not online slave devices according to its own
The ascending sequence of the corresponding number of device type is successively sent.
It should be noted that all devices type of support is numbered in advance by system developer.Each equipment
Device type number simultaneously as agreement transmit address and return information source identification.
In addition, if the online equipment queue table includes the device type of itself but do not include the device identification of itself,
Continue waiting for receive data and/or wait for one send waiting time (be slave devices initialization when obtain, usually by system
The initial latency market of developer's setting) sending device state packet.As it can be seen that in multiple slave devices of identical device type,
The equipment state packet of equipment of itself can be sent according to synchronous package by only becoming the online slave devices of host equipment at first, other
The slave devices of the device type were periodically attempted to send the equipment state packet of itself according to the waiting time itself initialized.
Step 340, the next equipment state packet of itself is sent to host equipment according to such duration to be sent.
This step can be realized by following two modes：
The first, when according to the reception of predefined type data packet (the equipment state packet of synchronous package or other slave devices)
Between, etc. duration to be sent determine the sending time of next equipment state packet, send itself to host equipment in the sending time
Equipment state packet.
For example, using synchronous package receiving time plus etc. duration to be sent (according to the receiving time of the synchronous package calculate
Go out) sending time of next equipment state packet is obtained, the equipment state of itself is sent to host equipment in the sending time
Packet.
For example, using other slave devices equipment state packet receiving time plus etc. duration to be sent (set according to this
Standby state packet is calculated) sending time of next equipment state packet is obtained, it is sent certainly to host equipment in the sending time
The equipment state packet of body.
Second, reach completing predefined type data packet (the equipment state packet of synchronous package or other slave devices) reception
When corresponding transmission waiting time, the equipment state packet of itself is sent to host equipment.
