Accompanying drawing explanation
Fig. 1 is schematic circuit diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of school bus stop signal arm control circuit as shown in Figure 1, comprises stop signal arm W1, Der Blink und Abblendschalter, indicator lamp LED, red strobe light LED1, yellow stroboscopic lamp LED2, the first relay J 1, second relay J 2, the 3rd relay J 3, battery isolator control K, the first K switch 1, second switch K2, the 3rd K switch 3 and power supply V1.
Described first relay J 1, its common port and open contact connect the control end of stop signal arm W1 respectively, one end of its coil connects the normally closed contact of the 3rd relay J 3 through second switch K2, the other end of its coil connects the positive pole of power supply V1 through wire fuse F1, battery isolator control K.The negative earth of described power supply V1.
Described second relay J 2, its common end grounding, its normally closed contact connects the yellow stroboscopic lamp control end of Der Blink und Abblendschalter, its open contact connects the red strobe light control end of Der Blink und Abblendschalter, the normally closed contact of one termination the 3rd relay J 3 of its coil, the other end of its coil connects the positive pole of power supply V1 successively through the first K switch 1, wire fuse F1, battery isolator control K.Described Der Blink und Abblendschalter, its mouth connects the input end of red strobe light LED1, the input end of yellow stroboscopic lamp LED2 respectively, and its power input meets power supply V1 through the first K switch 1, wire fuse F1 and battery isolator control K successively.
Described 3rd relay J 3, its common end grounding, one end the 3rd K switch 3 ground connection of its coil, the other end of its coil connects the positive pole of power supply V1 successively through the first K switch 1, wire fuse F1, battery isolator control K.Described 3rd K switch 3 and indicator lamp LED are all arranged in combination instrument, and the mouth of the control termination combination instrument controller of described 3rd K switch 3.Described indicator lamp LED one end ground connection, the other end connects the positive pole of power supply V1 successively through the first K switch 1, wire fuse F1, battery isolator control K.
Described stop signal arm W1 is several, is separately positioned on body side wall and vehicle body front bumper place.
Described vehicle is provided with speed sensor, and the mouth of this speed sensor is connected with the input end of combination instrument controller.
Described first relay J 1 is corner relay, and described second relay J 2 and the 3rd relay J 3 are five jiaos of relays.
Described power supply V1 is 24V car load power supply.
Principle of work of the present utility model is:
As when parking, first manual closing first switch of driver and second switch; Now, the 3rd switch disconnects, and the normally closed contact of the 3rd relay closes, thus makes the coil electricity of the first relay, and the open contact of the first relay closes, and stop signal arm works; Meanwhile, the coil electricity of the second relay, the open contact of the second relay closes, and Der Blink und Abblendschalter drives red strobe light to glimmer with certain frequency.When stopping, by the instruction of stop signal arm and red strobe light, the pedestrian and vehicle that make periphery can be noticed that school bus is dead ship condition, thus the safety of raising school bus.
When school bus changes motoring condition into by halted state: if driver is manual, first switch and second switch are disconnected, so, the coil no power of the 3rd relay, the normally closed contact of the 3rd relay closes, the open contact of the first relay disconnects, and stop signal arm quits work; Meanwhile, the normally closed contact of the second relay closes, but is not energized due to now Der Blink und Abblendschalter, and therefore yellow stroboscopic lamp and red strobe light all do not work.
If the first switch and second switch do not disconnect by driver, so, the vehicle speed data that combination instrument controller detects according to the speed sensor received, controls the break-make of the 3rd switch.If the speed of a motor vehicle is greater than speed of a motor vehicle threshold value, so, combination instrument controller drives the 3rd switch to close, then, the coil electricity of the 3rd relay, the open contact of the 3rd relay closes, and the open contact of the first relay disconnects, stop signal arm quits work, the normally closed contact of the second relay closes, yellow stroboscopic lamp work, now, indicator lamp is bright state, does not also disconnect to remind driver first switch and second switch.If the speed of a motor vehicle is not more than speed of a motor vehicle threshold value, so, 3rd switch remains open state, the normally closed contact of the 3rd relay closes, the coil electricity of the first relay, and the open contact of the first relay closes, stop signal arm works, the coil electricity of the second relay, the open contact of the second relay closes, red strobe light work; Now, the effect of stop signal arm and red strobe light is, pedestrian and the vehicle of prompting school bus periphery are noted just at the school bus of low speed driving, to ensure safety of school bus.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
