Embodiment
The object of this invention is to provide one and Intelligent household scene instruction set is saved in terminal device, directly the method calling the instruction of terminal device is controlled, comprising writing scene, saving scenario, calling scene three part by terminal device when user calls scene.
Scene composition part implementation method, scene is the set of a set of instruction, has space character between each instruction, and blank character is divided into three kinds: " & & ", " &; ", " &! ".Wherein, " & & " blank character represents and does not also terminate, below also have instruction send over and this joint data length sent not more than 255, in Single Chip Microcomputer (SCM) system, the subregion of a nonvolatile memory can not be too large, for 255, just need by the subregion limit system of limiting; " &; " also represent scene also do not terminate, below also have instruction send over and this joint data length sent more than 255, module needs to set up another a storage unit stores data; " &! " be ending full stop, there is no instruction below expression, terminate to write scene state.The instruction once transmitted due to Zigbee module can not be too many, and what these Dictating users needed a rule sends to gateway.Gateway is forwarded on the terminal device in Zigbee network more one by one by Zigbee communication modes, terminal device to receive after these instructions analyzing and processing one by one.
The process of saving scenario, for scene is saved in the storer of Zigbee module, first needs to set one section of storage space in the nonvolatile memory in its sheet.To arrange 20 scenes, arranging 0x0400 is first initial scene, totally 20, so when the length of a scene has exceeded the size of paging, such as 255 time, just measure by a constant offset and use next space, such as side-play amount is " 30 ", so concerning scene " 01 ", the storage space distributing to scene " 01 " is that 0x0400+01 rises, then, if page space that is 255 not, so next section of space of scene " 01 " is 0x0400+01+30.This storage means effectively utilizes space, just can be able to realize again by simple program, special solve deposit scene instruction more time, storage space can use across the page.When Zigbee module receives scene instruction, realize the process of storage scenarios by above-mentioned method.
The instruction of issuing terminal is that a rule sends, this is because the load of each bag length of Zigbee is limited.Article 1, be the instruction that notification terminal module prepares to receive scene, in instruction, have the code name writing scene.Each instruction is below dealt into terminal and just represents that what write has been the instruction in scene under this numbering.Form and the validity judgement work of instruction are realized by mobile phone A PP, and the single-chip microcomputer of zigbee module receives only information herein and algorithmically preserves.The storer of paging management Single Chip Microcomputer (SCM) program inside distributes and uses, and has been responsible for by single-chip microcomputer.Concrete grammar, as this section of above-mentioned introduction.
The invoked procedure of scene: after having stored scene, calling of scene is the mode of instruction calls, but the triggering of instruction can have various ways, both can be receive instruction triggers by Zigbee communication, also can be start by set date instruction triggers, can also be that the manual modes such as the button on terminal device trigger.Inner in program, be all that the triggering command of a given scenario code name has been come.When manual triggers, can have multiple button, such as three road soft-touch controls have three buttons, and so these three buttons can correspond respectively to three different scenes.
The implementation of scene, after the condition of trigger scenario is set up, terminal device, according to the difference of scene ID, inquires corresponding scene instruction at the storage space of correspondence, this scene instruction may have the instruction of nearly tens, sends these instructions and can not simply to circulate transmission.Will define a task events in Zigbee module internal processes, after triggering this task, every about 100 milliseconds, circulation performs this task, often performs a subtask, sends an instruction in instruction set.This is because the CPU of Zigbee module is multitask, long-term exclusive CPU can cause system crash.Also be avoid a terminal device time of concentration to take communication channel, the method that other equipment cannot normally work.Instruction in instruction set can be the instruction of mailing to other-end equipment, also can be the instruction sending to oneself to perform, and can also be to be sent to gateway to transfer to gateway forwards to arrive the instruction of other equipment.Can have the instruction of calling other scenes in instruction, the interlock realizing scene like this uses.More than illustrate and describe the technical method of a specific embodiment in detail, lower mask body combined command, introduce the effect of actual mechanical process under this implementation method and execution.
Actual mechanical process is, the first step, first edit instruction " AT+UCAST=****; AT+GCAST=S** " sends to gateway, wherein * * * * is the Zigbee terminal device numbering intending saving scenario, and * * is scene ID, chooses a scene ID when writing by user, each terminal device restriction can write 32 scenes, and scene ID is numbered 16 binary data 00 to 1F.This informs that Zigbee terminal device will prepare to start to write the instruction of scene, and such as choose a scene ID01, scene write by the soft-touch control being 1234 to terminal number, and sending instruction is " AT+UCAST=1234, AT+GCAST=S01 ".Can pass to corresponding Zigbee terminal device according to device numbering after gateway receives instruction, Zigbee terminal device can by oneself current status indication for writing scene state, and the scene ID extracted in instruction record.
Second step, editor's scene instruction is also sent to terminal.This Zigbee terminal device scene in the realization of reality, scene instruction is divided into scene instruction can through gateway, also can without gateway two kinds of situations.Wherein, scene instruction is through gateway, although refer to that this instruction set is kept in terminal device, but the instruction in this instruction set, first be sent to gateway, then by gateway forwards to another terminal device, this kind of situation is mutually far away for two terminal device intervals, terminal and terminal called may not freely time, this mode is referred to as r method.Another kind of situation be instruction in instruction set without gateway, that is be instruction in instruction set be directly be sent to other terminal device, this situation is that the relative position of these equipment is closer, and this mode is referred to as E mode.In second case, namely when instruction is without gateway, also have a kind of special circumstances, namely the instruction in this instruction set is outer to be sent out, but the set of ordering that this equipment oneself performs, such as, LED Color-changing lamp, realize the effect of one group of colour switching, namely can terminal scene instruction set in this way and realizing, this mode is referred to as C mode.
Above three kinds of modes give an order and write slightly different, and mainly for different modes, order format is different, to save storage area.Scene has three kinds of forms.Wherein, r method gives an order as " AT+UCAST=****, AT+GCAST=A, AT+UCAST=****; order * * ", and E mode gives an order as " AT+UCAST=****, AT+GCAST=A, * * * *; order * * ", and C mode gives an order as " AT+UCAST=****, AT+GCAST=A, order * * ".Wherein, first * * * * is the equipment code name of the Zigbee terminal device of saving scenario instruction; A * * * * next will be controlled the equipment code name of the terminal device of executable operations; " order " is the operation that terminal device will perform; * is ending symbol.End up symbol and previously described blank character herein, is divided into three kinds: " & & ", " &; ", " &! ", its implication and effect are as mentioned before.
User edits scenery control instruction set, steering order form " R ", " E " described above, " C " three kinds of modes,
Such as, under r method, in the soft-touch control of Zigbee terminal device numbering 1203, arrange terminal scenery control device numbering is the three-way switch of 1120, the terminal scene instruction that Shi Qi tri-tunnel all changes to closed condition is: " AT+UCAST=1203; AT+GCAST=A; AT+UCAST=1120, ACTIONbbb & & ";
Wherein, " ACTIONbbb " is an operational order of closing three tunnels; " & & " i.e. separator, also has other instructions after expression.Again under such as E mode, arrange in the soft-touch control of Zigbee terminal device numbering 1203 terminal scenery control device numbering be 1120 the terminal scene instruction that all changes to open mode of three-way switch full Shi Qi tri-tunnel be " AT+UCAST=1203; AT+GCAST=A; 1120, ACTIONaaa & & ".Again under such as C mode, arranging the terminal scene instruction that three-way switch that Zigbee terminal device is numbered 1203 all opens is " AT+UCAST=1203, AT+GCAST=A, ACTIONaaa & & ";
After editting instruction, instruction is issued gateway by a rule, and these steering orders can be stored in the storage space corresponding with scene ID according to scene ID label by terminal.
After writing scene, user can call setting to scene, and such as timing is called, triggered and call, and also what can not arrange and directly use mobile device to call execution scene.
When calling scene, user on the mobile apparatus editor terminal scene sends to gateway after performing instruction, and the execution instruction of calling terminal scene is still divided into three kinds, i.e. R, E, C, three kinds of modes.Call the scene instruction that in terminal device, self performs, order format is " AT+UCAST=****, AT+GCAST=C** ", wherein * * * * is terminal device numbering, and * * is the ID of terminal scene, such as, device numbering be 1234 LED desk lamp with dimmer switch have scene ID be 01 terminal scene, this terminal scene is the scene of control 1234 self color change, then its call instruction is " AT+UCAST=1234, AT+GCAST=C01 ", call the scene instruction through the control other-end equipment of gateway forwards in terminal device, form is " AT+UCAST=****, AT+GCAST=R** ", wherein * * * * is terminal device numbering, * is the ID of terminal scene, such as, device numbering be 1230 LED desk lamp with dimmer switch have scene ID be 03 terminal scene, this terminal scene is the scene that opertaing device is numbered the LED desk lamp with dimmer switch color change of 1256, then its call instruction is " AT+UCAST=1230, AT+GCAST=R03 ", call the scene instruction without the control other-end equipment of gateway forwards in terminal device, form is " AT+UCAST=****, AT+GCAST=E** ", wherein * * * * is terminal device numbering, * is the ID of terminal scene, such as, device numbering be 1230 a way switch opertaing device number be the Kai Heguan of a way switch of 1256, then its call instruction is " AT+UCAST=1230, AT+GCAST=E03 ".Called scene ID can be extracted in instruction after terminal receives terminal scene call instruction, the data of preserving in corresponding storage space are extracted again according to scene ID, then according to blank character and different method of calling, data one rule resolved to steering order and perform one by one or order sent one by one control other equipment.
Above embodiment is one of optimum embodiment of the present invention; art technology engineering staff it should be understood that the present embodiment can have multiple change, as long as but in terminal device saving scenario; and performed by terminal device, all within the claims in the present invention protection domain.
