Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a wireless manual control operation device for a signal controller that manually controls a large number of signal controllers by remote control.

(Summary of the Invention) The present invention enables manual control of a large number of signal controllers to be performed easily and efficiently from any location with less manpower.

(Prior art and its problems) When controlling traffic due to traffic stagnation or marching, it is necessary, for example, to significantly lengthen the travel time in the main direction, so signal control equipment is required to control the signal accordingly. It is configured so that it can be performed manually.

.

Conventionally, in order to carry out this manual control, one police officer or other person was assigned to each of a large number of signal controllers, and received commands via transceiver etc. from a supervisor monitoring the entire traffic flow from a pedestrian bridge, etc. Each signal controller was manually operated based on the following.

However, in such a conventional case, there is a drawback that a large number of people are required, including the number of signal controllers to be manually controlled, plus one supervisor.

Therefore, a manual control operating device is provided, and the operating device and each of the numerous signal controllers are connected via cables.
There are devices that allow multiple signal controllers to be controlled by operating from a location. However, since the signal controller is connected by cable, it is difficult and costly to connect to a signal controller far away, and for example, a manual control operation device is installed between two signal controllers. However, there was still room for improvement as the manual control device could not be moved and a person was required to monitor the traffic flow.

(Object of the Invention) The present invention has been made in view of the above circumstances, and an object of the present invention is to enable manual control operation of a traffic signal controller from any location without manual intervention. do.

a signal setting operation unit that sets each step signal of the step signal generation circuit to a frequency signal unique to each of the plurality of signal controllers; and a signal setting operation unit that receives return signals from each of the signal controllers to check the manual control state. and confirmation means.

According to this configuration, a person who intends to perform manual control operations moves to a location where he or she can view the entire traffic flow, such as on a pedestrian bridge, and while monitoring the traffic flow from that location, a person who intends to perform manual control operations moves to a location where the entire traffic flow can be observed, such as on a pedestrian bridge. , a mode signal or a step signal set to a unique frequency signal is transmitted, and the operation of the signal controller can be manually controlled as desired while being confirmed by the confirmation means.

Therefore, manual control operations are possible as long as the radio waves are within the reachable range and are chirping, and even a person can manually control a large number of signal control devices, making it possible to manually control a large number of signal control devices without human intervention. Ta.

Moreover, since it is wireless, it can be moved to any location, and can be operated while monitoring traffic flow by selecting a location with a good view, such as on a pedestrian bridge, making manual control operations extremely convenient. Now I can do it.
