To support more than 80% internet of things equipment, the table 1 (table 1 can be described later) described below is may refer to, so may be used
To greatly simplify development difficulty.For example：The APP of mobile terminal is by UART interface to telegon transmission=XXXXXXYYY, ID#
Order is (for example：=641223170, ID#), distribute a network ID to telegon.It is required that and other associations in Internet of things system
Adjust the network ID of device different, the radio communication channel of short range otherwise it is same.For security, the assignment principle of network ID
It is to try at random, it is discrete.
It is noted that in the present embodiment, network ID is 9 decimal number xxxxxxyyy, is converted into hexadecimal number
Be then the data of 4 bytes afterwards, the high 6 bit digital xxxxxx of network ID can define arbitrarily, represent password, network ID it is low 3
Yyy is 0-255, represents wireless physical channel, due to there is 256 wireless physical channels, by the way of artificially selection channel, this
The reliability of individual mode preferably, works relatively stable, and the present invention and ZIGBEE take energy scan to determine the method for channel not
Together.This definition of network ID so that password is combined with radio communication channel, it is possible to which the length with 4 bytes is whole
Count to represent.The network ID of each telegon is generated with the APP generations of mobile terminal or by the MAC Address of gateway, only net
Network ID identicals terminal device could communicate.Worth one is mentioned that network ID is to change.
The APP of step S02 mobile terminals, which sequentially passes through gateway and UART interface and sent to telegon, meets AT command set number
Start order according to the registration of form：In this step, the APP of mobile terminal sequentially passes through gateway and UART interface and sent to telegon
The registration for meeting AT command set data format starts order, registers startup order as=999999999, R1# orders.
Any button of step S03 long-press terminal devices, terminal device sends upper count off by the wireless physical channel of agreement
According to telegon, telegon is received after reported data is added to registration table by terminal device, then sends current network ID to end
End equipment, notifies terminal device modification network ID, and exit registration mode：In this step, any button of long-press terminal device,
Terminal device sends reported data to telegon by the wireless physical channel of agreement, and telegon receives after reported data and to set terminal
It is standby to be added to registration table, current network ID is then sent to terminal device, notifies terminal device modification network ID, and exit registration
Pattern.
Step S04 terminal devices are received after current network ID according to the nothing included in current network ID and current network ID
Line physical channel works：In this step, terminal device is received after current network ID, according in current network ID and current network ID
Comprising wireless physical channel be operated.
Step S05 repeats the above steps S02 to step S04 registration process, registers and completes until all terminal devices：
In this step, the S02 that repeats the above steps is registered until all terminal devices and completed to step S04 registration process.
Step S06 when telegon can not directly control terminal equipment when, the APP of mobile terminal gives corresponding router to send
Route comprising node ID rewrites order, and corresponding router is entered route rewrites status, then sends and includes device id
Order, after the terminal device addition in need by route, sent to corresponding router and include the end of node ID
Order, and corresponding router is terminated rewriting process：In this step, when telegon can not directly control terminal equipment when, move
The APP of dynamic terminal sends the route comprising node ID to corresponding router and rewrites order, and corresponding router is entered approach
By rewrites status, the order for include device id is then sent, after institute's terminal device in need by route is added, to correspondingly
Router send and include the end order of node ID, and corresponding router is terminated rewriting process.Assuming that telegon is with setting
The terminal device that standby ID is 730000222 can not directly be controlled farther out, it is necessary to the router that node ID is 730000111, then
Need an operating process that 730000222 this device id are written to 730000111 routing table.Detailed process is：It is mobile
The APP of terminal first sends out=730000111, ZY# orders to router, into route rewrites status, then send=
730000222, WA# orders (send=730000222, WM# orders) if removing to router, institute's process in need
After the router addition of route, send=730000111, ZX# orders to router and terminate rewriting process.
It is noted that equipment has a device id in each terminal, device id is 9 decimal numbers, is converted into
Be the data of 4 bytes after hexadecimal, device id dispatches from the factory fixed, can not change, device id at least include type, pattern and
Parameter, device id represents big type with the numeral started, and numeral thereafter represents small type；That is, different types of end
End equipment is distinguished with the numeral started, and telegon obtains the device id of terminal device after terminal device registration, and is stored in
Registration table.
Traditional communication protocol includes source device address and destination device address, and of the invention simplifies Internet of Things communication protocol
By simplification, the two addresses are used when different, only with an address, the address when data downstream is destination device address,
And address during data uplink is the address of source device.That is, the device id in the down order that telegon is sent is mesh
Device id when marking the ID of terminal device, terminal device active transmission or response telegon order is source address.In the present embodiment,
It is that terminal device enters row address distribution according to device id.The allocation tables of terminal device as shown in table 1, should in table 1
Simplify Internet of Things communication protocol and done address distribution to various kinds of equipment for smart home and Internet of Things, so only need to device id
It just can recognize that device type and major parameter.The content of table 1 is specific as follows：
Table 1
In the present embodiment, network ID constitutes the address of 8 bytes with device id.Network ID is can be changed by user
, device id dispatches from the factory fixed, can not change.The problem of effectively can reducing repeated code in application process in this way.
Even if device id is identical, as long as network ID is different, does not result in yet and control by mistake.
