Description
Technical field
The present invention relates to a kind of triggering command and triggering method that is applicable to multiple intelligent gateway, belong to the Communication Control Technology field of intelligent gateway.
Background technology
Along with the concept of wired home and Intelligent office is progressively popularized, the intelligent integral technology is used in reality, mainly makes up to realize by middle control platform, intelligent gateway and multiple sensors node.Along with the development of intelligent gateway, what it expedited the emergence of out is of a great variety: the triggering command of existing intelligent gateway mostly is simple instructions such as sending [opening], [pass] or [beginning report], [stopping report], [timing wake-up], [external interrupt wakeup]; The frame format of common triggering command as shown in Figure 1.Frame head wherein: comprise immobilized substance, such as FE; Order: distinguish the effect of this command frame, common are control command, acquisition, wake command etc.; Length: the length of this frame; Data: the user data of concrete application scenarios; FCS: check code.
Generally setting different triggering command for user's needs controls intelligent gateway, this brings many follow-up inconvenience just for the communication between middle control platform and the intelligent gateway, and how therefore adopting, the triggering command of form can become the technical problem that present stage need to need to be resolved hurrily by the Unified Communication form.And used triggering command is single and sends, and triggering command can not be adjusted the transmission form automatically according to the dynamic accepting state of intelligent gateway.
Summary of the invention
In order to solve above technical deficiency, the invention discloses a kind of triggering command that is applicable to multiple intelligent gateway.
The invention also discloses and utilize above-mentioned triggering command realization to the triggering method of multiple intelligent gateway.
Technical scheme of the present invention is as follows:
A kind of triggering command that is applicable to multiple intelligent gateway, comprise frame head, trigger packet header, order, length, data and FCS, described triggering packet header comprises the number of repetition instruction, requires to report receipt instruction, failure retransfer delay instruction, the instruction of failure retransfer number of times and cipher mode instruction; Described number of repetition instruction is 3 binary codes, to require to report the receipt instruction be that 1 binary code, failure retransfer delay instruction are that 4 binary codes, the instruction of failure retransfer number of times are 2 binary codes; The cipher mode instruction is 2 binary codes.
A kind ofly utilize above-mentioned triggering command to realize triggering method to intelligent gateway, the communication steps of namely utilizing triggering command of the present invention to control between platform, the intelligent gateway in realizing is as follows:
(1) the control platform is initiated triggering command in
Middle control platform according to the frame format of the triggering command that is applicable to multiple intelligent gateway, calculates and forms triggering command frame, i.e. a triggering command according to actual needs; And send to intelligent gateway by ICP/IP protocol;
(2) the described triggering command of intelligent gateway analyzing step (1)
Intelligent gateway receives the triggering command that middle control platform is sent by ICP/IP protocol, and according to the frame format of triggering command, parses triggering command; According to the difference of triggering command, intelligent gateway calculates and forms the application instruction of the correspondence of local definition; And simultaneously application instruction is mail to corresponding destination node.Described corresponding destination node refers to: for example application instruction is to obtain temperature value, and then corresponding destination node is to realize the node of measurement or collecting temperature.
Further preferred according to the present invention, described intelligent gateway converted described application instruction to the frame format of corresponding host-host protocol before the destination node to correspondence sends application instruction.
Advantage of the present invention is:
Triggering command of the present invention comprises frame head, triggers packet header, order, length, data and FCS, and described triggering packet header comprises the number of repetition instruction, requires to report receipt instruction, failure retransfer delay instruction, the instruction of failure retransfer number of times and cipher mode instruction; Adopt the Unified Communication form, this triggering command is adjusted the transmission form automatically according to the dynamic accepting state of intelligent gateway, guarantees that instruction efficiently carried out by destination node.
Description of drawings
Fig. 1 is the frame format of existing triggering command;
Fig. 2 is the frame format of intelligent gateway triggering command of the present invention.
Embodiment
Below in conjunction with embodiment and Figure of description the present invention is described in detail, but is not limited to this.
Embodiment 1,
As shown in Figure 2.
A kind of triggering command that is applicable to multiple intelligent gateway, comprise frame head, trigger packet header, order, length, data and FCS, described triggering packet header comprises the number of repetition instruction, requires to report receipt instruction, failure retransfer delay instruction, the instruction of failure retransfer number of times and cipher mode instruction; Described number of repetition instruction is 3 binary codes, to require to report the receipt instruction be that 1 binary code, failure retransfer delay instruction are that 4 binary codes, the instruction of failure retransfer number of times are 2 binary codes; The cipher mode instruction is 2 binary codes.
A kind of utilization as described in Example 1 triggering command realization namely utilizes the communication steps of controlling between platform, the intelligent gateway in the triggering command realization of the present invention as follows to the triggering method of intelligent gateway:
Take the control collecting temperature as example, obtain the network address and be the temperature value of 1234 node,
(1) the control platform is initiated triggering command in
Middle control platform according to the frame format of the triggering command that is applicable to multiple intelligent gateway, calculates and forms a triggering command frame according to actual needs, i.e. triggering command, as shown in Figure 2:
Frame head: 0xFE
Trigger packet header: 0x0634(number of repetition 3, do not need receipt, unsuccessfully postpone 3s, failure retransfer 1 time is without encrypting)
Order: RTV(Read Temperature Value)
Length: 0x04
Data: 0x1234
FCS：0x40
Be that triggering command is: FE634RTV04123440; And by ICP/IP protocol, send to intelligent gateway;
(2) the described triggering command of intelligent gateway analyzing step (1)
Intelligent gateway receives the triggering command that middle control platform is sent by ICP/IP protocol, and according to the frame format of triggering command, parsing triggering command is RTV; According to the difference of triggering command, intelligent gateway calculates and forms the application instruction GTV of the correspondence of local definition; And simultaneously application instruction is mail to corresponding destination node.
The network address is 1234 node reception and resolves the application instruction frame that the parsing application instruction is: FE634GTV04123455.
According to the information that triggers packet header, the network address is that 1234 node will initiatively gather local temperature value, and uploads 3 times.
Described intelligent gateway converted described application instruction to the frame format of corresponding host-host protocol before the destination node to correspondence sends application instruction.
