[embodiment]
Accompanying drawing below in conjunction with the embodiment of the present invention is explained and illustrated the technological scheme of the embodiment of the present invention, but following embodiment is only the preferred embodiments of the present invention, not all.Embodiment based in mode of execution, those skilled in the art are other embodiments that obtains under the prerequisite of not making creative work, all belong to protection scope of the present invention.
With reference to Fig. 1, the electromagnetic valve control method of the embodiment of the present invention, this solenoid valve is to be connected to master chip by electronic switch, the electronic switch of the present embodiment is selected controllable silicon, master chip is used for judging whether solenoid valve needs work, if master chip judges that solenoid valve needs work, timer starts, enter zero passage delay procedure, that is to say, judging that solenoid valve needs after work, be not solenoid valve to be switched at once, but there is a time delay process, the time of this time delay process is set by timer, as timer, setting break period is 2ms, delay time is 2ms, arrive while setting delay time, controlled silicon conducting, timer interrupts, solenoid valve energising work, when the electrical current of solenoid valve arrives phase place during zero point, controllable silicon turn-offs voluntarily, solenoid valve power-off.
With reference to Fig. 2, solenoid valve electrical current oscillogram by the present embodiment can be found out, between solenoid valve electrical current phase place A at zero point and phase place B at zero point, form crest, needed time of control program operation is the time that two zero passages are interrupted, and in prior art, time period from phase place A at zero point to phase place B at zero point, solenoid valve is all in full power "on" position, so heating value is larger, but the present embodiment is because set the break period of timer, realized zero propagation, by silicon controlled Delayed conducting, solenoid valve is only switched in the corresponding time period between phase point C and phase place B at zero point, compared to existing technology, in a control program running, reduce the current"on"time of solenoid valve, the heat being produced by power consumption also reduces, thereby reduced the heating value of solenoid valve self.
The time delay process of the present embodiment is except controlling break period by timer, can also control by timer interruption times, be that timer produces once and interrupts every set time, the number of times that timer interrupts is stored in the register of master chip, and on master chip, prestore the interruption setting value of timer, when timer interruption times arrives interruption setting value, the delay time meter of setting is full, for example: timer produces once and interrupts every 1ms, every generation is once interrupted, interruption times on register adds 1, it is 5 that the timer prestoring on master chip interrupts setting value, when timer interrupts after 5 times, controlled silicon conducting, solenoid valve energising work, delay time is controlled as 5ms.
According to the characteristic of electromagnetic valve work, can find out, solenoid valve has stem structure and elastic reset structure conventionally, during energising, stem structure action, during power-off, elastic reset structure is ordered about stem structure and is resetted, but be understandable that: when power-off instantaneous, although elastic reset structure function is on stem structure, but stem structure can't be in the instantaneous reset immediately of power-off, also there is time delay, that is to say: even solenoid valve power-off, the stem structure of solenoid valve within a period of time still in working position, and can not reset immediately, therefore, the embodiment of the present invention is in whole control procedure, solenoid valve is intermittent energising work, in service in a secondary program, reduce the current"on"time of solenoid valve, but do not affect the normal work of solenoid valve.For example: the one-period of 220V-50Hz Ac is 20ms, according to the characteristic of elastic reset structure in solenoid valve, keep the time of solenoid valve stem structure action only to need 3/4 cycle, be 15ms, if the setting operating time of solenoid valve is 60s, so in fact, energising and the power-off of solenoid valve hocket, accumulative total current"on"time of solenoid valve is 45s, and the power-off time accumulative total of solenoid valve is 15s.
So the embodiment of the present invention can reduce the current"on"time of solenoid valve in the situation that not affecting the normal work of solenoid valve, reduces heating value, has also saved electric energy simultaneously.
