Abstract
The utility model belongs to an EPS fault alarm time delay control system. The system comprises an alarm sampling circuit (1) and an EPS fault alarm time delay circuit (2). The system is characterized in that a comparator U1B is connected in parallel with a comparator U1A in the EPS fault alarm time delay circuit (2); a fourth pin of the comparator U1B is connected with a resistor R3, a resistor R2, a resistor R8, one end of a switch S1 and an emitting electrode of a triode Q1; a fifth pin is connected with one end of a resistor R5 and the other end of the S1; a sixth pin is connected with one end of a resistor R4 and the other end of the R3; a seventh pin is connected with one end of a R6 and an anode of a diode D3; a eighth pin is connected with the other end of the R4, one end of a R1, the fifth pin of a LM358N comparator UIA, cathodes of diodes D1 and D2 and one pin of a buzzer LS1. According to the utility model, the D3 is used to carry our feedback; the comparators U1A and U1B compare and generate a signal cycle; a continuous pulse signal is generated so that an alarm sound is emitted or light is generated. The fault can be processed timely and an accident is avoided.
Description
Technical field
The utility model belongs to electrical control gear, particularly a kind of EPS fault alarm delay control system.
Background technology
In the electric control system of electric equipment, all be provided with fault alarm function, in general circuit, signal generating source provides a pulse signal, reports to the police with hummer or light; This mode breaks down at machine, when signal generating source can only provide a single pulse signal, warning circuit can only be reported to the police by single, after pulse disappears, report to the police and also disappear immediately, the staff being taken place sometimes do not hear the sound or do not see light in the very first time, can not get timely processing, influences work or cause the accident.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, a kind of EPS fault alarm delay control system that can continue to send alerting signal is provided.
The used technical scheme of the utility model technical solution problem is: a kind of EPS fault alarm delay control system, comprise warning sample circuit, civil power accessory power supply, inversion accessory power supply and EPS fault alarm delay circuit, it is characterized in that in EPS fault alarm delay circuit and LM358N comparer U1A LM358N comparer U1B in parallel.The emitter of 4 pin connecting resistance R3, R2, R8, switch S 1 one ends and the triode Q1 of LM358N comparer U1B, the other end of 5 pin connecting resistance R5 one ends and switch S 1,4 pin connecting resistance R4 one end and the R3 other ends, 7 pin are by the positive pole of resistance R 6 one ends and diode D3, the pin of 5 pin of the other end of 8 pin connecting resistance R4, the end of R1, LM358N comparer UIA, the negative pole of diode D1, D2 and hummer LS1.
The beneficial effects of the utility model are: utility model is utilized diode D3 feedback, LM358 comparer U1A and U1B relatively produce signal cycle, produce the pulse signal that continues, and make hummer send alarm sound or light, the staff can in time be handled, avoid accident to take place.
