The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: automatic control traffic safety hurdle, People's Bank of China crossing as shown in fig. 1, comprise People's Bank of China's signal lamp and garage's signal lamp, it is characterized in that: also be provided with People's Bank of China's safety fence 24 at the People's Bank of China crossing, 25, the garage crossing is provided with garage's safety fence 26,27, the safety fence flexible by driven by motor is installed on the track on ground, travel switch 9 is equipped with at the track two ends, 10,13,14, People's Bank of China's safety fence 24,25, garage's safety fence 26,27, People's Bank of China's signal lamp 18,19,22,23 and garage's signal lamp 16,17,20,21 are controlled by the timing automatic control circuit.
In Fig. 2, described timing automatic control circuit is made up of timing reverse circuit 30, safety fence control circuit 28 and the signal lamp control circuit 29 of single phase ac mains-supplied, and described timing reverse circuit 30 is in series and is constituted by bistable state timer 2, power amplifier 3, relay line bag 4; Described safety fence control circuit 28 has two groups of circuit for controlling motor parallel with one another, and each group circuit for controlling motor has often opening and normally closed roadblock contact- making switch 5,6 of a pair of interlock, inserts the electric capacity pin of the two-way exchange motor of two parallel connections respectively; Described signal lamp control circuit 29 is often opened and normally closed signal lamp contact-making switch 15 by a pair of interlock, is connected in series to two groups each four signal lamps of lighting simultaneously in parallel respectively and constitutes.
Three pairs of normally-open normally-close contact-making switches in Fig. 2 circuit are subjected to the control of relay line bag 4 simultaneously.
As shown in Figure 1, People's Bank of China and garage's entrance side at the People's Bank of China crossing, all be provided with safety fence as roadblock, it is respectively garage's safety fence 1, garage's safety fence 2 27, People's Bank of China's safety fence 1, People's Bank of China's safety fence 2 25, these four roadblock safety fences directly stand on the respective rail of road surface setting, by the driven by motor extension and contraction control, the near-end of road surface track and far-end all are equipped with the normally closed travel switch of timing closing, it is respectively garage's safety fence travel switch 1, garage's safety fence travel switch 2 14, People's Bank of China's safety fence travel switch 1, People's Bank of China's safety fence travel switch 2 10, the effect of travel switch is that circuit is disconnected, motor stops operating, recover closed behind the delay time that the travel switch process of band time-delay is preset, motor is remained in operation.
Opposite at safety fence is equipped with traffic lights, is respectively vehicle red light 1, vehicle green light 1, garage's red light 2 17, garage's green light 2 21, People's Bank of China's red light 3 22, People's Bank of China's green light 3 18, People's Bank of China's red light 4 23, People's Bank of China's green light 4 19.Traffic lights cooperate interlock with safety fence, when garage's red light was bright, garage's safety fence trailed and waits for, People's Bank of China's green light is lighted, and People's Bank of China's safety fence shrinks and waits for; When garage's green light was bright, garage's safety fence shrank and waits for that People's Bank of China's red light is lighted, and People's Bank of China's safety fence stretches and waits for.
Safety fence and signal lamp are by regularly automatic control circuit control as shown in Figure 2, timing reverse circuit 30 among Fig. 2 plays the effect of the "on" position that changes relay line bag 4, after the output signal process power amplification of bistable state timer 2, at high level state, relay line bag 4 just be in electricity condition, this moment, the constant open contact switch of relay was all closed, the constant close contact switch all disconnects, behind the timing through the bistable state timer 2, output low level, relay line bag 4 dead electricity, this moment, the constant open contact switch of relay all disconnected, and the constant close contact switch is all closed.Relay line bag 4 is transition status in turn in this two states just.And signal lamp and motor all are subjected to the control of relay contact switch.
In safety fence control circuit 28, the connect travel switch of this motor place safety fence near-end and far-end of two coil common ports of single phase bidirectional alternating current generator, the two ends in addition of motor link to each other with civil power with normally closed contact-making switch through often driving contact-making switch respectively, always have a contact-making switch closure at any one time, if this moment, travel switch was in closure state, motor will rotate, by the time regularly arrive flip-flop transition, another contact-making switch closure, two contact-making switch swap statuses, motor counter-rotating.
In signal lamp control circuit 29 shown in Figure 2, two groups of signal lamps that each four signal lamp is formed are lighted in turn, and these two groups of signal lamps are often opened contact-making switch or the control of normally closed contact-making switch by relay respectively.
Action in conjunction with People's Bank of China's safety fence and signal lamp is that example illustrates that the course of action of motor is as follows: a level of bistable state timer 2 output also picks up counting, relay line bag 4, with People's Bank of China safety fence motor 1, the normal open switch closure of People's Bank of China's roadblock contact-making switch 5 that People's Bank of China's safety fence motor 28 links to each other, People's Bank of China's safety fence motor 1, People's Bank of China's safety fence motor 28 is just changeing, People's Bank of China's safety fence 1, People's Bank of China's safety fence 2 25 is done contractile motion, with garage safety fence motor 1, the normal open switch closure of garage's roadblock contact-making switch 6 that garage's safety fence motor 2 12 links to each other, garage's safety fence motor 1,2 12 counter-rotatings of garage's safety fence motor, garage's safety fence 1, garage's safety fence 2 27 is done extensional motion; At this moment, one group of signal lamp: garage's red light 1, garage's red light 2 17, People's Bank of China's green light 3 18, People's Bank of China's green light 4 19, owing to connecting with signal lamp contact-making switch 15 normal open switch of closure and being lighted.
When People's Bank of China's safety fence 1, People's Bank of China's safety fence 2 25 are retracted to respectively when running into the near-end travel switch, People's Bank of China's safety fence motor 1, People's Bank of China's safety fence motor 28 shut down because of switch opens circuit respectively; When garage's safety fence 1, garage's safety fence 2 27 are stretched to respectively when running into the far-end travel switch, garage's safety fence motor 1, garage's safety fence motor 2 12 also shut down because of switch opens circuit respectively; The delay time one of wait travel switch promptly can be distinguished closure to travel switch, at this moment, the rollover states of bistable state timer 2 overturn in time before this, and the constant open contact of contact-making switch disconnects and the constant close contact closure, another group signal lamp is lighted, and last group of signal lamp extinguishes.Motor change simultaneously turns to, People's Bank of China's safety fence 1, People's Bank of China's safety fence 2 25 are done extensional motion, garage's safety fence 1, garage's safety fence 2 27 are done contractile motion, run into the far-end travel switch up to People's Bank of China's safety fence 1, People's Bank of China's safety fence 2 25, garage's safety fence 1, garage's safety fence 2 27 run into the near-end travel switch, enter the time-delay stand-by period.So circulation realizes the timing automatic conversion of safety fence and signal lamp.
