Embodiment:
When vehicle is opened in workshop outside workshop, vehicle can first pass through the first optoelectronic switch 5 in Fig. 1, due to vehicle
Light when passing through between the first optoelectronic switch 5 and the first reflector 6 is kept off, and the first optoelectronic switch 5, which can generate a signal, to be made
The coil of intermediate relay KA1 in Fig. 2 obtain it is electric, KA1 coil obtain it is electric after, KA1 normally opened contact 5-9 closure keep coil self-locking；Together
When KA1 normally opened contact 6-10 be closed, time relay KT1 coil must establish beginning timing by cable；KA1 normally opened contact 7-11 closure is cried out simultaneously
Words device (alarm 2) beginning is propagandaed directed to communicate according to recording substance, and pedestrian is reminded to pay attention to avoiding.When time relay KT1 setting
Time, then KT1 delay break contact 1-9 was disconnected, then intermediate relay KA1 coil losing electricity, and the contact 7-11 of KA1 is disconnected, cried out
Words device stopping is propagandaed directed to communicate.
When vehicle past workshop external-open out of workshop, vehicle can first pass through the first optoelectronic switch 4 in Fig. 1, due to light
A signal, which can be generated, by the first optoelectronic switch 4 of gear makes the coil of the intermediate relay KA2 in Fig. 2 obtain electric, and KA2 coil obtains electric
Afterwards, KA2 normally opened contact 5-9 closure keeps coil self-locking；KA2 normally opened contact 6-10 closure simultaneously, time relay KT2 coil obtains electric
Start timing；The normally-closed contact 2-10 of KA2 is disconnected simultaneously, therefore when vehicle outputs workshop by optoelectronic switch 1, intermediate relay
The coil of device KA1 can not obtain electric, and the normally opened contact 7-11 of KA1 is off-state always, therefore megaphone will not propaganda directed to communicate, and realize
The alarm that vehicle one direction enters is propagandaed directed to communicate function.When the time relay KT2 setting time then, the delay break contact of KT2
1-9 is disconnected, intermediate relay KA2 coil losing electricity, the normally-closed contact 2-10 closure of KA2, when vehicle is again outside workshop toward workshop
The coil of KA1 can obtain electric alarm again and propaganda directed to communicate when inside opening.Megaphone propaganda directed to communicate the time length can by time relay KT1 into
Row setting.When the time of time relay KT2 setting needs to reach required for optoelectronic switch 1 greater than vehicle from optoelectronic switch 2
Between.
