The working principle of the engine motor oil location alarm of present embodiment is following:
One, when the car load power switch is opened, the ECU energising, power supply gives capacitor C 1 charging through resistance R 1; If this moment, thermistor RT was immersed in machine oil the inside (safe oil level position); This thermistor RT is because machine oil thermolysis and temperature is low, and thermistor RT resistance is little, and capacitor C 1 charging is fast; In capacitor C 1 charging, the high petential of triode T1 collector electrode output is also giving capacitor C 2 chargings.But discharge immediately after in the time that capacitor C 1 detection is provided with, being full of electricity, the 3 pin output low potential of 555 ICs 1 stops to capacitor C 2 chargings; Because under machine oil oil level normal condition; Be set to the duration of charge of 1 duration of charge of capacitor C less than capacitor C 2, cause capacitor C 2 can not give the 2 pin discharge of 555 ICs 2 all the time, 3 pin of 555 ICs 2 also just can not be in high petential all the time; Under the machine oil normal condition, LED is not reported to the police.When capacitor C 1 discharge off, 3 pin of 555 ICs 1 are in low potential, and resistance R 2 is the current-limiting resistance of triode T1.Triode T1 exports high petential again, gives capacitor C 1 charging, capacitor C 2 chargings again simultaneously, accomplishes the one action circulation.Resistance R 4, resistance R 5 are that resistance is just established in the time-delay of 555 ICs, 1,555 ICs 2.
Two, under machine oil oil level abnormal conditions, to the C1 charging, thermistor RT was not immersed in the machine oil the inside and generated heat fast power supply this moment through resistance R 1; Thermistor RT resistance is big, and the C1 duration of charge is greater than C2, and the high petential that this moment, triode T1 was in is charging to C2 always; At the appointed time; When C1 also was not full of electricity, C2 had been full of the 2 pin discharge that electricity is given 555 ICs 2, and 3 pin of 555 ICs 2 are in high petential; Triode T2 conducting output high petential, the LED flicker is reported to the police.
The motor with above-mentioned engine motor oil location alarm of present embodiment, said motor are provided with aforesaid engine motor oil location alarm.The alarm body of said engine motor oil location alarm is connected in through bindiny mechanism on the machine oil mouth of motor, and sensor measuring bar slave hydraulic fluid port stretches into.
Should be pointed out that the above embodiment can make those skilled in the art more fully understand the invention, but do not limit the present invention in any way creation.Therefore; Although this specification has carried out detailed explanation with reference to accompanying drawing and embodiment to the invention,, those skilled in the art are to be understood that; Still can make amendment or be equal to replacement the invention; In a word, all do not break away from the technological scheme and the improvement thereof of the spirit and the scope of the invention, and it all should be encompassed in the middle of the protection domain of the invention patent.
