Embodiment
To combine accompanying drawing that the embodiment of the invention is described further below.
As shown in Figure 1, reduce among the method and system embodiment of stand-by power consumption of wireless transceiver system in the present invention, comprise the steps:
Step S11 begins: as previously mentioned; In wireless transceiver system, the standby power consumption of radiating portion can not considered, and can when button is pressed, just be circuit supply; When not having button to press; Power supply not to be connected, and need not consider its power consumption basically, mainly needs to consider the standby power consumption of receiving unit.In this step, the microprocessor start program of receiving unit.
Step S12 judge WDT regularly the overflow indicator position whether be 0: owing to regularly overflow when waking up when the WDT of system house dog, its watchdog reset zone bit can become 1 by 0, and program can start anew to move.Therefore, in this step, earlier judge whether the watchdog reset zone bit is 1, as be 1 (house dog have timing to overflow wake up), then execution in step S15; As be 0, execution in step S13 then.
Step S13 initiation parameter is set: in this step; Parameter initialization comprises that the house dog when microprocessor is set to be waken up overflows number of times; Because the time that house dog is overflowed is certain, has set the number of times that overflows of house dog, has also just set the length of one's sleep of microprocessor in the receiving trap.
Step S14 moves sleep program: after setting parameter, in this step, the microprocessor of receiving trap gets into sleep state, when the house dog generation is overflowed for the first time, returns step S11 and begins to carry out.
Step S15 accumulative total WDT regularly overflows and reaches set point number whether: in this step, judge whether the number of times of the WDT of accumulative total surpasses the number of times of setting, if surpass, and execution in step S16, otherwise, execution in step S14.
The variable zero clearing that step S16 accumulative total WDT regularly overflows number of times: with the WDT of accumulative total overflow the number of times zero clearing, prepare to finish this sleep state.
Step S17 finishes sleep to the receiving circuit operation master routine that powers on: finish this sleep state, power on for the each several part of receiving trap, comprise and accept circuit, move the master routine of the microprocessor of this receiving device, prepare acknowledge(ment) signal.
Step S18 judges whether power-on time has reached setting value: owing to when parameter setting, set power-on time, promptly in any one-period; For the power-on time of microprocessor and receiving circuit can not surpass this time; Therefore in this step, judge whether this power-on time reaches this setting value, if; Execution in step S14, microprocessor gets into sleep state; If not, execution in step S19.
Step S19 drives timer, judges receiving code: open timer, begin the signal of waiting for that emitter sends out.
Step S20 receiving code OK: judge whether the receiving code in the signal that receives is correct, promptly whether this signal sends to this receiver, if, execution in step S21, if not, execution in step S18 returned.
Step S21 operation master routine is carried out relevant action: in this step, when receiving correct receiving code, microprocessor is decoded to it, finds corresponding action, and carries out.
Whether receive receiving code again behind the step S22 setting-up time: behind the execution of step S21, judge after timer is opened, whether to receive receiving code once more, in this way, execution in step S20; If not, execution in step S14.
In the present embodiment; The shortest power-on time during intermittent power supply should have long enough; At least should be able to be in this power-on time section; Let the microprocessor of receiving trap can receive all transmitting, and through judge whether to receive desired launching code decide the microprocessor of follow-up receiving trap be this continuation sleep (the ultralow power consumption stand-by operation pattern of intermittent power supply) still this ends sleep get into lasting normal mode of operation (the microprocessor power consumption of receiving trap at this moment obviously increases severely).In the present embodiment; Need not to wait for that the microprocessor of receiving trap can receive all transmitting; As long as judge some crucial bit data wherein, whether the microprocessor that can determine receiving trap should continuations be controlled and the power supply that continues receiving circuit still is that this is got back in the sleep again and goes.
Usually; The shortest power-on time of intermittent power supply is to confirm like this: because the launching code of wireless transceiver system is made up of synchronous code (or claiming the forward position sign indicating number), address code, numeric data code etc.; And after the microprocessor of receiving trap regularly intermittently wakes up; Usually to wait until coding that interpretation to 2 at least time receives all protocol compliant require and just think after the unanimity as a result to receive decoding effectively, just can let the microprocessor of receiving trap get into normal mode of operation afterwards.So; The shortest power-on time of intermittent power supply pattern; Receive effective transmit coded signals no matter have or not; All must reserve the time that guarantees enough to run through 2 complete and effective transmit coded signals (the BIT data that comprise all constituents such as synchronous code, address code, numeric data code) at least, create necessary time conditions for receiving at least 2 complete and effective transmit coded signals, so duration of power supply is longer.
In the present embodiment; As long as once satisfactory synchronous code and address code (also claiming " extraneous signal identity code ") are arrived in the microprocessor interpretation; Need not to wait until follow-up numeric data code and other yard BIT of the first string of interpretation again; Also need not to wait again interpretation to finish the effective transmit coded signals of the 2nd string, can finish sleep and get into normal mode of operation, and continued power is in power supply/reception data mode to guarantee reception, signal transformation circuit always; Numeric data code as the back receives is not right, just gets into sleep again at once.Thus; The shortest power-on time of reserving; Only need get final product for receiving 1 synchronous code and necessary time conditions of address code creation in the complete transmit coded signals, because the BIT position has significantly reduced, the shortest power-on time of the intermittent power supply standby mode of design has also just shortened dramatically like this; Dutycycle can reach more than 1: 5, and significantly reduces the standby average current.What need cooperation is: the every emission of coded signal once; Its duration should be greater than the T.T. (being referred to as a time cycle) of receiving trap microprocessor length of one's sleep+intermittent power supply time; Can cover the time period that the receiving circuit in any time cycle is waken up to guarantee to transmit, make receiving circuit not miss the reception of any external transmit coded signals once.
In the present embodiment, when the WDT of system house dog is regularly overflowed when waking up, its watchdog reset zone bit can become 1 by 0, the program operation that can start anew.Through the number of times of inquiry when beginning and accumulative total watchdog reset zone bit jumping 1, can calculate and set the time of receiving trap microprocessor sleep.Every regularly the waking up of receiving trap microprocessor come once, i.e. whether inspection has the reception signal, as does not have, and gets into sleep state again.If any receiving effective extraneous signal, then get into normal mode of operation.Normal work period as there is not the signal of reception in the setting-up time always, then gets into sleep again, to reach the power saving purpose.
Wherein, earlier judge whether the watchdog reset zone bit is 1, as be 1 (house dog have regularly to overflow wake up), cumulative number then as also not reaching the number of times of setting, does not also reach the number of times of setting like cumulative number, and then watchdog reset zone bit zero clearing continues to sleep; Reached the number of times of setting like cumulative number, then directly operation is opened and is regularly interrupted, declares master routine parts such as receiving code, key scan.
In the present embodiment, the house dog of the length of one's sleep=house dog time of regularly overflowing * setting that the receiving trap microprocessor is set is regularly overflowed number of times, and regularly the time of overflowing can remove to set correlation parameter through the mask option to house dog.After receiving trap microprocessor house dog is regularly waken up certainly, the operation master routine, at first whether the power-on time of judgement setting arrives, and as also being less than, then the receiving trap microprocessor continues to the receiving circuit power supply, and the execution extraneous signal receives and a judgement yard supervisor; Power-on time as setting arrives, and the receiving trap microprocessor judges do not receive effective extraneous signal identity code, jumps again and removes to carry out sleep program; Receive effective extraneous signal identity code like the receiving trap microprocessor judges; Then prolong receiving circuit power-on time to 1 second; Receiving all external transmit coded signals, as the extraneous signal that receives decodes successfully, then gets into operate as normal (non-power saving) pattern.As there is not the signal of reception in the follow-up setting-up time of receiving trap microprocessor always, then MCU just gets into sleep again, recovers the intermittent power supply pattern of receiving circuit simultaneously, to reach power saving effect.
Attention: key scan should select the I/O mouth of arousal function, so as between receiving trap microprocessor sleep period also response button in good time.And need add an instruction of jumping to master routine in sleep instruction back; Because it is to wake the statement that sleep instruction back is carried out in the back up that button I/O mouth wakes up; Watchdog reset wakes the statement of then not carrying out sleep instruction back up; Directly from the beginning the return information beginning is carried out, and this wakes up different with watchdog reset.
Owing to adopt house dog timing wake-up mode, and house dog is regularly overflowed to reset and just makes the program operation that starts anew again, but can't change the data in the RAM, and these are different with other reset mode, so also just do not have the drawback of the information of brushing former storage.
In addition, in the present embodiment, during intermittent power supply operation master routine, be added with the anti-endless loop instruction of " CLRWDT " in the master routine; As not receiving signal in the setting-up time, then jump again and remove to carry out sleep program.Because of nothing in the sleep program " clear WDT " instruction, so can not occur to wake the problem of sleep certainly up with house dog because of operation " clear WDT ".
In the present embodiment, also disclosed a kind of wireless transceiver system, comprise receiving trap and coded signal thereof launch time greater than length of one's sleep of the microprocessor of said receiving trap and said microprocessor by the emitter of the power-on time sum after waking up; Said receiving trap comprises that also being used to be provided with the sleep state that gets into sleep state time length is provided with module 1, is used to judge whether the signal identification module 3 that breaks away from said dormant sleep state detection module 2 and be used for during said microprocessor power supply, judging whether to receive correct synchronous code and address code.Sleep state is provided with module 1 and comprises that house dog is set overflows the number of times of number of times module 11 is set; The number of times that this number of times is provided with module 11 settings combined with the time of overflowing that microprocessor itself is had at every turn, had fixed each dormant total time of entering of microprocessor.Sleep state judge module 2 comprises being used to discern whether said house dog overflow overflows judge module 21, be used to judge that said house dog overflows the number of times judge module 22 whether number of times reaches setting value; Overflow judge module 21 through judging that house dog overflow indicator position is 0 or 1 to judge that house dog is overflowed and whether take place; And house dog of every generation is overflowed; Number of times judge module 22 all will add the number of times that overflows of its record 1 back and detect and once to overflow number of times and whether reach above-mentioned number of times the set number of times of module 11 is set; Surpass set point number like this number of times, mean that arrive the length of one's sleep of microprocessor, should withdraw from sleep state; Do not surpass set point number like this number of times, then continue sleep.Signal identification module 3 comprise be used to judge the power-on time that saidly receives signal receiving circuit and signaling module 31 that whether synchronous code and address code conform to this machine, when said synchronous code conforms to address code, keep said microprocessor power supply to make the power-on time Postponement module 32 of the coding that it can the said emitter emission of complete reception and be used to judge said microprocessor whether with the power-on time control circuit 33 that reaches setting-up time; When signal receiving circuit and signaling module 31 are judged the synchronous code that receives and address code when correct, 32 work of power-on time Postponement module, the power-on time that prolongs microprocessor and receiving circuit guarantees that microprocessor can receive complete launching code; Power-on time control circuit 33 then is used for when microprocessor does not receive signal, the power-on time of microprocessor and receiving circuit in the control sleep state.In addition, receiving trap also be included in its when being triggered with the microprocessor of said receiving trap by the button that wakes up in the sleep state 4; Said button 4 is connected said microprocessor and has on the input/output end port 5 of arousal function.Therefore, no matter how, triggering button 4, the state of microprocessor all can make it get into duty.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
