The sensing means 100 is installed along the railroad R at a distance from the worksite W from the worksite W adjacent to the railroad R or the railroad R. [ The sensing means 100 senses the railroad car T approaching the worksite W along the railroad R and outputs a sensing signal.

The sensing means 100 is installed to output a sensing signal at a place where the worker W can safely escape with sufficient time and may be installed at a distance of 800 m to 1500 m from the workshop W. [

1, the sensing means 100 is installed on a railway R in the direction in which the railway vehicle T enters the worksite W, and the railway R is installed on the railway R as shown in FIG. When the vehicle T is a disconnection line running on both sides, it is installed on the right and left sides around the worksite W. In the case of a double line, as shown in Fig. 3, the railway T in the direction in which the railway car T enters the worksite W R respectively.

The control means 200 is installed in the work area W, and is provided at a place that does not interfere with the work. The control means 200 receives the sensing signal output from the sensing means 100 and outputs a warning signal to the warning means 300.

The warning means 300 is also installed in the workshop W. [ The warning means 300 is installed in a place that does not interfere with the operation and is capable of effectively warning the operator. The warning means 300 outputs a warning signal of the control means 200 in the form of a combination of sound, light (light), numeral or letter, or two or more kinds thereof, ).

The warning means 300 can be installed together with the control means 200 as a control means 200 and can be installed at a distance from the control means 200 and can be provided as wired or wireless It can receive a warning signal from the control means 200 through communication and warn the operator.
