Abstract

The utility model discloses a kind of time delay anti-jamming device of city bus car door, comprise for the single-chip microcomputer of control gate switch, the drive circuit of control gate switch, the enabling electromagnetic valve be electrically connected with drive circuit and electromagnetic valve of closing the door, put in place for the cylinder of control gate switch and Men Guan testing circuit, drive circuit and the Men Guan testing circuit that puts in place is electrically connected with single-chip microcomputer respectively, and enabling electromagnetic valve is connected with cylinder respectively with electromagnetic valve of closing the door; Also comprise the delay adjustment knob for adjusting the automatic door opening time, described delay adjustment knob is electrically connected with single-chip microcomputer; Advantage is by the delay adjustment knob setting automatic door opening time, when single-chip microcomputer after reaching this time do not receive a pass put in place testing circuit feedback signal, single-chip microcomputer opens car door by drive circuit by the solenoid control cylinder that opens the door automatically, thus prevents from crushing passenger.

Description

A kind of time delay anti-jamming device of city bus car door

Technical field

The utility model relates to a kind of time delay anti-jamming device of city bus car door.

Background technology

What in urban transportation tool, occupy important proportion is city bus, and because China is populous, the people of upper and lower car door is many, and the contingency of bus door folder people often occurs.Although doorframe is enclosed with rubber, but what adopt due to city bus is the switch of electrical control car door, and switch gate institute is stressed comparatively large, and needs driver just can open by door open button after folder people, easily crushes passenger, may cause injures and deaths time serious.

Utility model content

Technical problem to be solved in the utility model is to provide the time delay anti-jamming device that a kind of car door time-out does not close the city bus car door of automatic door opening when putting in place.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of time delay anti-jamming device of city bus car door, comprise for the single-chip microcomputer of control gate switch, the drive circuit of control gate switch, the enabling electromagnetic valve be electrically connected with drive circuit and electromagnetic valve of closing the door, put in place for the cylinder of control gate switch and Men Guan testing circuit, drive circuit and the Men Guan testing circuit that puts in place is electrically connected with single-chip microcomputer respectively, and enabling electromagnetic valve is connected with cylinder respectively with electromagnetic valve of closing the door; Also comprise the delay adjustment knob for adjusting the automatic door opening time, described delay adjustment knob is electrically connected with single-chip microcomputer.

Compared with prior art, the utility model has the advantage of by the delay adjustment knob setting automatic door opening time, when single-chip microcomputer after reaching this time do not receive a pass put in place testing circuit feedback signal, single-chip microcomputer opens car door by drive circuit by the solenoid control cylinder that opens the door automatically, thus prevents from crushing passenger.

As preferably, the automatic door opening time of the setting of delay adjustment knob is 3 ~ 4 seconds.According to the passenger traffic situation adjustment suitable automatic door opening time, be adjusted to 3 seconds when common passenger traffic, during passenger traffic peak, be adjusted to 4 seconds.

As improvement, remind the alarm of driver after being also included in time delay automatic door opening, alarm is electrically connected with single-chip microcomputer.

Accompanying drawing explanation

Fig. 1 is circuit block diagram of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.

This preferred embodiment is a kind of time delay anti-jamming device of city bus car door, comprise for the drive circuit 2 of the single-chip microcomputer 1 of control gate switch, control gate switch, power module 3, door closing switch 4, door open switch 5, the enabling electromagnetic valve 6 be electrically connected with drive circuit 2 and electromagnetic valve 7 of closing the door, close for the cylinder of control gate switch and existing door the testing circuit 8 that puts in place, power module 3 is electrically connected with single-chip microcomputer 1 and drive circuit 2, drive circuit 2 and the Men Guan testing circuit 8 that puts in place is electrically connected with single-chip microcomputer 1 respectively, and enabling electromagnetic valve 6 is connected with cylinder respectively with electromagnetic valve 7 of closing the door; Also comprise the delay adjustment knob 9 for adjusting the automatic door opening time, delay adjustment knob 9 is electrically connected with single-chip microcomputer 1.Remind the alarm 10 of driver after being also included in time delay automatic door opening, alarm 10 is electrically connected with single-chip microcomputer 1.Its circuit block diagram as shown in Figure 1.

The automatic door opening time of the setting of delay adjustment knob 9 is 3 ~ 4 seconds, the lockup of general city bus be 2 seconds some more but 3 seconds less than.Set 3 seconds for delay adjustment knob 9, the pass gate signal receiving door closing switch 4 when single-chip microcomputer 1 starts timing, and close to put in place signal if receive put in place the door of testing circuit 8 of a pass in 3 seconds, then anti-pinch is inoperative; If exceed 3 seconds and do not receive a pass to put in place signal, then anti-pinch works, and single-chip microcomputer 1 output signal opens door to drive circuit 2 by enabling electromagnetic valve 6 control cylinder.
