Accompanying drawing explanation
Fig. 1 is the circuit diagram of gig operational failure annunciator.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of gig operational failure annunciator, comprises chip IC 1, resistance R1, sensor P and relay J, one end contact resistance R2 of described sensor P, resistance R3, resistance R5, power supply VCC, the pin 4 of chip IC 1 and the pin 8 of chip IC 1, the other end of sensor P connects electric capacity C1, the pin 2 of resistance R1 and chip IC 1, the other end of resistance R1 connects a fixed end of potential device RP1, and the sliding end of potential device RP1 connects the other end of electric capacity C1, electric capacity C2, resistance R4, the anode of diode D3, the negative electrode of diode D4, relay J, loudspeaker B, another fixed end of potential device RP1 and the pin 1 of chip IC 1, the other end of resistance R2 connects the other end of electric capacity C2, the pin 6 of chip IC 1 and the pin 7 of chip IC 1, the pin 3 of chip IC 1 connects the negative electrode of diode D1, the anode of diode D2, the negative electrode of diode D3 and the other end of relay J, the other end of the negative electrode contact resistance R4 of diode D2, the other end of the anode contact resistance R3 of diode D1, the other end of resistance R5 connects the contact J-1 of relay J, and the other end of the contact J-1 of relay J connects the anode of diode D4 and the other end of loudspeaker B.
Chip IC 1 is NE555 type time base circuit.Relay J is for often to drive electric shock relay.Diode D1 and diode D2 is light-emitting diode.
Principle of work of the present utility model is: the principle of design of circuit is when gig overload or drive belt are swung loosening, and the secondary speed of gig can be slack-off.According to this feature, utilize the trigger level of 555 and the relation of RC discharge and recharge time constant, design this warning circuit.The magnetic switch that sensor P is made up of a permanent magnet and dry-reed tube is formed, and the former tightens up on the driven wheel, and the latter is fixed on ad-hoc location.When rotating speed is normal, often turn around, because magnetic switch is closed, C1 is charged.Regulator potentiometer RP1, makes the charging valtage on C1 (when normal speed) a little higher than 1/3VCC, makes the mouth of 555 (3 pin) keep low level.When due to thus fall make secondary speed lower than normal speed time, the voltage on cond C1 due to discharge time lengthen and lower than 1/3VCC, chip IC 1 overturns, circuit export become high level.Now, be connected on the relay conducting of 3 pin of chip IC 1, the J-1 adhesive of its contact, the loudspeaker B thereon and light-emitting diode D4 that makes to connect sends sound and light alarm.Circuit structure is simple, components and parts are few, cost of manufacture is low, use sensor as the detecting element of gig operative condition, once gig motor internal to occur rotating speed abnormal, will trigger alarm circuit, send sound and light alarm, timely prompting user maintenance, therefore, it is possible to actv. reduces gig fault accident therefore.
