As is well known, trains are a vehicle that emphasizes safety and driving efficiency compared to other vehicles because of the characteristics of mass transportation.

Therefore, in order to secure the safety of trains and improve the efficiency of operation, the train automatic stop device (AUTO-MATIC TRAIN STOPPER: hereinafter referred to as ATS), the train automatic control device (AUTOMATIC TRAIN CONT- ROL: hereinafter referred to as ATC), and the train automatic operation device Train operation automatic control devices such as (AUTOMATIC TRAIN OPERATION: hereinafter called ATO) have been developed and used.

However, the conventional automatic train operation control device as described above is composed of a ground device installed on the track, a vehicle-mounted device mounted on the train, etc., which is a high-tech equipment which secures the safety of the train and improves the driving efficiency, and its configuration is complicated. In addition, since installation costs and operating costs are expensive and professional training has to be performed, there is a problem in that installation and operation cannot be made without securing a large budget.

Therefore, on a track that does not have an automatic train control system such as ATS, ATC, or ATO, a signal source dedicated to the signal resides, providing information about the distance from the preceding train and the passage of the point. It was notified by hand signal, or manually operated signal light, which required a lot of manpower, and caused an unexpected situation to the signal source and could not signal or caused an accident if the signal was wrong. There was a problem. An example of operating the signal form as described above is India, where a person resides at a certain distance or a major section in India to inform the engineer of the track occupancy status of the train.

An object of the present invention is to solve the conventional problems as described above, in particular, after installing the wheel detection means and the traffic light at a predetermined distance along the track, and whether the train passes through the wheel detection means and occupies the track occupancy By detecting the state and automatically controlling the operation of the traffic light, to provide an "automatic traffic light automatic control device and its control method" that can be unattended automatic control of the traffic light at a simple installation and low cost.

That is, if the number of wheels of the train passing through one automatic traffic light control device is counted and transmitted to the next traffic light automatic control device, the next traffic light automatic control device stores data on the number of wheels transmitted. When the number of wheels passing through is equal to the number of wheels transmitted, it is recognized as the passage of trains and the traffic lights are linked to control the traffic. It is to inform the train automatically through the lighting of the lights.

For convenience of description, the Excel counter will be referred to as a wheel detection unit and a microcomputer as a control unit.

The accelerator counter is a device that detects a wheel by using an effect of decreasing the gain of the oscillation frequency due to a change in inductance when a metal object approaches the LC oscillation circuit. As illustrated in FIGS. 4 and 5, the LC counter An antenna unit (11a) formed of an oscillation circuit and installed in a railway line; A detector (11b) for detecting a gain change due to a change in inductance that changes when a wheel of a train approaches the antenna unit; It consists of a hold part 11c and a regulator part 11d.
