Embodiment
Following 1-2 by reference to the accompanying drawings, is further described the application's scheme:
A scanning recognition method between wireless lighting control system middle controller and actuator, comprises the following steps:
A) make actuator enter the remote activation step of configuration status, have following operation:
Arrange actuator under lasting "on" position, within T1 second, complete the operation that one or many power-off powers on again, be considered as activation and enter configuration status, this configuration status continues T
2second, in this duration T
2in second, actuator receives the search command that any controller sends, and resolves the controller ID obtained in temporary the last search command, and this controller ID temporary storage time is T
3second, for follow-up test and configuration operation;
B) based on the actuator scanning step of the Aloha algorithm improved, following operation is had:
Controller is set and enters configuration status, the Aloha algorithm improved is used to scan, in local scope, send search command and configuration order, described search command includes the ID of controller, described configuration order include to actuator action setting some instructions or instruction code.
The actuator scanning step of the described Aloha algorithm based on improving comprises following operation further:
1. search initiated by controller, generates a timeslot number and a random number;
2. controller starts to send first time search instruction, comprise this timeslot number and random number in this search instruction, controller enters and waits for actuator response status immediately, waits for " the software time slot * timeslot number " time, exceeding this time then repeats aforesaid operations, sends search instruction next time;
3. actuator receives described search instruction and responds, and one of them time slot of random selecting from the time slot search instruction, waits for that the time of this time slot returns self information to backward controller;
4. controller received by actuator feedack in " the software time slot * timeslot number " time, resolved and recorded the ID of actuator and be inserted in the middle of next search instruction;
5. actuator receives search instruction again, when the ID containing himself in search instruction then enters silent status, no longer responds search;
6. controller sends configuration order to the actuator of Record ID, is received, complete configuration by this actuator.
Described actuator receives search instruction, then judge whether it is new search by random number; If so, this search is namely responded; No, then enter silent status.
Described controller controls by intelligent terminal, and described intelligent terminal has the visual operation interface of Controller-oriented; By the configuration status of described intelligent terminal active controller, the result of the search that controller is initiated reports to intelligent terminal, is shown with list or graphics mode by intelligent terminal.
Described intelligent terminal initiates the connecting test to the actuator found by controller, is specially, and controller finds test instruction to appointment actuator, is received and feedback-related information by this actuator, to confirm its coupling connection status.
When the first time search feedback result that controller is initiated is zero, then initiate second time search with the second timeslot number at least again.
As shown in Figure 1-2, apply scanning recognition method of the present invention, the concrete configuration process of wireless lighting control system is:
First keep actuator "on" position (controlled lamp is bright), then at T
1complete the operation that a time power-off powers on again in=2 seconds, then actuator enters configuration status, continues appropriate time (as T
2=30 seconds), this T
2in time, actuator can be arbitrarily controlled device search, and the ID of the controller of temporary the last search, this ID can keep in a period of time (as T
3=30 minutes) for follow-up test and configuration operation.
Actuator not response controller search command when not being in configuration status; Controller, outside configuration status, does not send search command and configuration order yet; Be not performed device keep in ID controller cannot to this actuator carry out other operation; There is provided the fail safe of system with this, actuator can not be paired to other controller by mistake; Even if certain actuator is mismatched for a certain reason, also can be corrected by Timeliness coverage.
After controller and actuator all enter configuration status, use the Aloha algorithm improved to scan, find the actuator existed in surrounding environment, and impose suitable configuration.
Search instruction (subsidiary timeslot number) initiated by software, controller is made to start search procedure, controller generates a random number, and start to send first time search instruction, comprise this timeslot number and random number in instruction, controller enters and waits for that (time-out time is total slot time to actuator response status, if timeslot number is 32 immediately, each time slot is 20ms, then the time-out time of this search is 640ms);
Actuator receives this instruction and at configuration status, then judge whether it is new search by random number, if so, this search is namely responded, random selecting time slot from the time slot instruction, wait for that the time of this time slot is to rear, returns self information (such as to controller, timeslot number is 32, then random selecting one value in 1-32, as 8, and each time slot is 20ms, then return information after wait 160ms);
Controller receives the information of actuator, to this information of software upload, and the ID recording actuator is inserted in next search instruction, the controller wait timeout time arrives, then search is next time initiated, if actuator receives search instruction again, if contain self ID in instruction, enter silent status and no longer respond search (only the new search triggered, is judged by random number);
If controller current search result is 0, then sending a timeslot number is again the search of 8, if this search is without returning, exits search, if return, and the search operation before continuing.
The algorithm that present patent application realizes can guarantee that the actuator of preassembled Lighting Control Assembly was found rapidly in the system configuration stage, even if the installation site of these actuators can not be seen by visual, also can complete configuration effort within a few second.
Table below shows the test result of realized algorithm:
| Actuator quantity | Minimum search time (ms) | The maximum search time (ms) | Average search time (ms) |
| 10 | 1600 | 2080 | 1840 |
| 20 | 2080 | 3360 | 2720 |
| 30 | 2720 | 4000 | 3360 |
| 40 | 3360 | 4000 | 3680 |
| 58 | 4000 | 4640 | 4320 |
The realization of this algorithm can the installation of simplified intelligent lamp light control system and layoutprocedure greatly, makes the DIY of System Implementation become possibility.
Above-mentioned preferred implementation should be considered as illustrating of the application's scheme implementation mode, allly to duplicate with the application's scheme, technology that is approximate or that make based on this is deduced, replaces, improvement etc., all should be considered as the protection range of this patent.
