Description
Technical field
The present invention relates to the processing method of a kind of infrared ray to the injection device pulse received by receiving terminal of infrared.
Background technology
Present known infrared ray to the injection device receiving terminal when receiving infrared pulse signal, it all is continuous reception, that is to say, the infrared pulse signal that the injection device transmitting terminal is sent at infrared ray, in a single day infrared ray is opened the power supply of injection device receiving terminal, and infrared ray is to be in operating state uninterruptedly to the infrared ray receiver module of injection device receiving terminal all the time.Adopt such receiving handling method certainly will cause infrared ray to the bigger power consumption of injection device receiving terminal consumption.
Present most infrared ray all adopts mains-supplied to the injection device receiving terminal, though power consumption is bigger, can not influence the normal use of infrared ray to the injection device receiving terminal; But application along with the new type solar energy electric supply installation, infrared ray all is directly to take from these power supplys by solar energy converting by connecting line to the working power of injection device transmitting terminal and receiving terminal, because solar panels are with illumination time length relation to be arranged, how to have maximally utilised solar energy, infrared ray just counts for much to the power consumption of injection device.These solar powered infrared rays to injection device in, the weather that how to solve long-time a run of wet weather brings continuous power supply to have defective, wherein how many electric energy of correlation consumption has substantial connection, and some will be unable to do what one wishes, can't obtain round-the-clock popularization in a lot of places.The direct battery-powered infrared ray that has is to injection device, and the consideration of power consumption also is very important, becomes technical emphasis naturally so how to reduce the work energy consumption.
Summary of the invention
Technical problem to be solved by this invention is to provide the processing method of a kind of infrared ray to the injection device pulse received by receiving terminal of infrared at above-mentioned prior art, utilize infrared ray after this method can not only better must keep to the injection device receiving terminal and infrared ray to clock between the injection device transmitting terminal synchronously, can also effectively reduce self energy consumption.

Preferably, the present invention can also comprise
Step 5, described processor enter holding state after each infrared ray finishes receiving the infrared pulse of injection device transmitting terminal, wait for of the arrival of next infrared ray to the infrared pulse of injection device transmitting terminal, processor neither equally be in the operating state of highly energy-consuming like this, but is in the holding state of low energy consumption between two continuous infrared pulses.
Described t is better more than or equal to the pulse sequence width of zero infrared pulse signal that arrives smaller or equal to two current actual reception.
As improvement, the present invention can also comprise
Step 6, processor are every a Fixed Time Interval cycle, receive in real time the infrared pulse signal that the infrared ray of injection device receiving terminal successful matching is sent the injection device transmitting terminal with described infrared ray, the time interval of the respective pulses in the waveform of the time interval of this infrared pulse signal that receives and standard is compared, calculate the clock offset of transmitting terminal and receiving terminal, the pulse sequence waveform of the standard infrared pulse signal preserved in the described step 1 is revised according to the side-play amount of clock.
This step is used for the correction to the preprocessor clock drift that works long hours, and can guarantee the transmitting terminal that works long hours and the clock synchronization of receiving terminal.
Compared with prior art, the invention has the advantages that:
1,, can guarantee preferably that infrared ray is to synchronous to clock between the injection device transmitting terminal of injection device receiving terminal and infrared ray by step 2, step 3;
2, pass through step 4, make power supply t before each infrared ray is to the infrared pulse arrival of injection device transmitting terminal of infrared ray receiver module open during second, after each infrared ray finishes receiving the infrared pulse of injection device transmitting terminal, close, make infrared ray reach energy-saving effect preferably the injection device receiving terminal.
