Description of drawings
Fig. 1 is the structured flowchart of the first embodiment of control coding study light fixture of the present utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
The first embodiment:
Because the address information of each telepilot is different, whether thereby can distinguish with telepilot during light fixture is communicated by letter by described telepilot address information is in the telepilot of light fixture pairing, so control coding described in present embodiment study light fixture is by changing the address signal of the pairing telepilot of storing in the light fixture, thereby realize the fast pairing between the light fixture and different remote.
So as shown in Figure 1, the control coding of present embodiment study light fixture comprises a wireless receiving chip 1, a decoding chip 2, a processor 3, a storer 4 and a switch 5.
Wherein said storer 4 be used for storage with the telepilot address information of the telepilot of described light fixture pairing.Storer described in the present embodiment 4 adopts EEPROM to realize.
Described wireless receiving chip 1 is used for receiving the control signal that an extraneous telepilot sends.And the message transmission rate between telepilot and the light fixture is that 1K-3K is optimum condition, so adopt the high-frequency transmission frequency of 315MHx in the present embodiment.
Described decoding chip 2 is used for decoding one first telepilot address information from described control signal, and described decoding chip 2 also decodes one second telepilot address information again from described control signal.
Wherein said decoding chip 2 also comprises a circulation correcting unit 21, whether described circulation correcting unit 21 is used for more described the first telepilot address information identical with described the second telepilot address information, if not identical, then abandon described the first telepilot address information.
And the described switch 5 of present embodiment by the closed and disconnected of switch control described decoding chip 2 whether from control signal decoding obtain the first telepilot address information, namely when described switch 5 closure, the operation that described decoding chip 2 is decoded, when switch 5 disconnects, stop the decode operation of described decoding chip 2.
The specific works principle of present embodiment is as follows:
In the situation that telepilot and light fixture have matched, transmitter code chip in the employing of telepilot end, for example the PT2240B chip of golden ploughshare Electronics Co., Ltd. is launched through the wireless transmitter module modulated high frequency signal through the coded pulse of certain rule, and frequency is 315MHZ.
Thereby at the light fixture end, pulse when the wireless receiving chip 1 with same frequency is reduced to emission with the high-frequency signal of receiving is after decoding chip 2 analyzing and processing, export corresponding telepilot address information and corresponding light fixture control information, the motor positive and inverse of control light fixture and lighting circuit etc.
When telepilot needs and light fixture when matching, need to be with described switch 5 closures, decoding chip 2 enters duty at this moment.Thereby can change the telepilot address information of storage in the storer 4 of light fixture, thereby the again pairing between realization light fixture and the telepilot.
At this moment described telepilot transmits control signal to described light fixture, and wherein detailed process is:
This moment is at the telepilot end, the user clicks any one switch of telepilot self, it is the button of telepilot, switch sections provides push button signalling to coding chip PT2240B chip, coding chip is encoded signal according to certain rules, wherein the preamble code of coding described in the present embodiment, address code and numeric data code form, and described signal is launched through the high-frequency signal that wireless transmitter module is modulated into 315MHz.
After this at the light fixture end, described wireless receiving chip 1 receives the high-frequency signal of described 315MHz and is sent to the pulsewidth of the waveform of the described high-frequency signal of described decoding chip 2 identifications, tell numeral 1 and 0, then identify remote control mode and the function key of control signal according to 1 and 0 combination, isolate address code and numeric data code.Wherein control signal described in the present embodiment is comprised of synchronous preamble code, data 0 and data 1.The form that is described control signal one frame is: what receive first belongs to synchronous preamble code, receive again afterwards 20 bit address, and then receive 4 bit data codes, distribute the data of an above-mentioned frame after, if the button of telepilot is not decontroled, then continue circulation data one by one.
So in decode procedure, that at first considers detects synchronous preamble code, if known the composition of synchronous preamble code, how just gone again to detect relatively easily.So at first need to detect the high level signal of 200uS in the present embodiment.The method that detects has a variety of, here article a kind of method wherein: by time-delay 20uS, if reading the interface of decoding chip 2 is the value of high level register, need to delay time again and read again the interface of decoding chip 2 behind the 20us, continue to detect like this, test is to surpassing 30 times or high level, and this code is synchronous preamble code scarcely so, at this moment will jump out this circulation.Detected low level signal if be no more than 30 times, consider the existence of time error in the present embodiment, so will judge whether so between 15 to 25, namely the time error scope of above data thereby can not make decoding error cause error code between positive and negative 10%.If in this scope, just think that the high level of synchronous preamble code has detected, go to judge the low level of synchronous preamble code, because the low level of the synchronous preamble code of setting in the present embodiment is 6000us, need to weigh take 60us as benchmark the low level signal of synchronous code this moment, preserve count value with a register equally, constantly the data of decoding chip 2 interfaces are read in circulation, when reading decoding chip 2 interface high level, relatively this value is in the error range of defined, consider equally time error, this value can be located at 5000us in the scope between the 7000us in the present embodiment, this value of depositing is exactly in 80 ~ 120 scope so, and so far, the low level of preamble code then detects and finishes synchronously.If not in this scope, not the low level of synchronous preamble code so just,
If preamble code detects unsuccessfully synchronously, described decoding chip 2 is abandoned data, waits for the control signal that again has described wireless receiving chip 1 to receive.
After if preamble code detects successfully synchronously, to consider that also can data 24 bit codes of measuring circulate, whether namely detect described data 24 bit codes by circulation correcting unit 21 receives correctly, wherein in the present embodiment for the first time detected 24 bit codes obtain the first telepilot address information by the temporary Ji Ci Time of internal register, detected 24 bit codes for the second time, i.e. the second telepilot address information, see that the described second time, detected 24 bit codes compared with for the first time detected 24 bit codes, identical then for circulating; Not identical then for not capable of circulation, namely think undesired signal.Concrete method of testing namely can be measured with software delay, also can measure with timer.Because of the interference problem of considering that distance causes, come measurement data with the software delay method as far as possible.Less demanding if adjust the distance, but when higher, can realize with timer the measurement of data to the accuracy requirement of decoding.Do not meet above-mentioned rule if wherein have a bit code in testing process, this group test result need be lost.
The detection method of concrete data has multiple, for example judges it is that 0 or 1 circulation gets final product for 24 times according to the width of the high level that tests out.If the data-signal that detects 0 or 1 is identical, and is namely capable of circulation, not identical then for not capable of circulation, can think undesired signal.We also can test then judgement to high level and low level if require height, if high-low level all satisfies data qualification, degree of accuracy can be higher like this.
After 24 yards of data are finished decoding, also to distinguish address and the data of telepilot, wherein address information is front 20 in the present embodiment, data are rear four, the address of remote control and data need to separately be processed, wherein said address information, namely the telepilot address information is used for distinguishing different telepilots, and described data are used for determining the function allocation of respective keys on the telepilot.
The address information that this preprocessor 3 need to be about to store among described address information and the EEPROM is compared, if there is not this address information, processor 3 will be carried out and write code operations, and address code is write among the EEPROM, namely the address information in the EEPR0M is covered.
So far just finished the pairing between telepilot and the light fixture.
The second embodiment:
Present embodiment, is specially to the Pairing behavior of having simplified further between telepilot and the light fixture on the basis of the first embodiment:
Processor 3 is only for the telepilot address information that described control signal telepilot address information is covered in the described storer 4 in the present embodiment.
Be that processor described in the present embodiment 3 is no longer judged whether having stored described telepilot address information in the storer 4, so when re-starting pairing, no matter be all direct telepilot address informations of storage in the overlaying memory 4 of the telepilot that matched or the address information of the telepilot of new needs pairing, and in the use impression of user side without any difference.
Each embodiment in this instructions all adopts the mode of going forward one by one to describe, and identical similar part is mutually referring to getting final product between each embodiment, and each embodiment stresses is difference with other embodiment.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these embodiments under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection domain of the present utility model.
