A state signal of the switch is transmitted to the control unit 16, an operation is performed based on a command signal from the control unit 16, and an operation status signal is returned to the control unit 16. The up and down vehicles C can pass alternately, and the vehicles C can flow smoothly without congestion.

The above-mentioned obstacle sensor detects an obstacle that hinders the closing operation of the blocking bar 2, particularly a vehicle C that enters. Then, the control unit 16 receives the obstacle detection signal of the obstacle sensor, shifts the blocking bar 2 during the closing operation to the opening operation, and when the obstacle sensor stops detecting the obstacle, the vehicle sensor 6 described above. The number of vehicles is determined based on the vehicle detection signal of the second vehicle sensor 17, and the signal of the traffic light 4 is switched and the blocking bar 2 is opened and closed in accordance with the number of vehicles, so that the vehicle C passes without congestion.

The circuit breaker 1 includes a blocking bar 2 and a traffic light 4.
The control can be switched between automatic control and manual control. As this manual control, either a completely manual type or a semi-manual type may be adopted. The completely manual type controls the opening and closing of the blocking bar 2 and the interlocking of the signal light of the traffic light 4 by a manual remote control operation based on visual judgment of a staff member, and is mainly used in an emergency. Semi-manual type has two breakers 1
One of the circuit breakers 1 is used as a base unit, and one person in charge controls the system by manual remote control operation based on visual judgment, and the other circuit breaker 1 is interlocked with the operation of the base unit. Used when the site is complex and there are many construction vehicles. In addition, any of a fully automatic type and a semi-automatic type may be employed as the automatic control. The fully automatic type controls the system by judging the data of the vehicle sensor 6 and the second vehicle sensor 17 and transmits a command signal to each of the circuit breakers 1, and is generally used. The semi-automatic type performs control that gives priority to this manual operation when a manual remote control operation is performed by a staff when interrupt processing is performed in a fully automatic type, and when an emergency vehicle such as an ambulance or a construction vehicle is passed.
