The video information is a method of operating a steel cut or a pedestrian guide module that is a video.
The method of claim 7,
The seventh step of determining the pedestrian safety line,
Correcting the pedestrian safety line by comparing the obtained pedestrian crossing line and the pedestrian safety line overlaid on the test image information on the remote manager computer; And
A method of operating a pedestrian guide module comprising the step of receiving setting video information including the modified pedestrian safety line.
The method of claim 9,
The seventh step of determining the pedestrian safety line,
And receiving confirmation information including the determined pedestrian safety line from the remote manager computer.
The method of claim 8,
Receiving reset information of a pedestrian safety line from the remote manager computer; and
The method of operating a pedestrian guide module further comprising the step of performing the first to eighth steps by the reset information.
In the guide system comprising a pedestrian guide module,

The method of claim 14,
RF module for transmitting and receiving a radio frequency (RF) signal;
Time display, a display module for displaying the set value of the second processor unit; And
And a GPS (Global Positioning System) module that extracts time information from a satellite signal and delivers it to the second processor unit,
The RF module, the display module and the GPS module is a guide system detachably mounted to the main board.
The method of claim 15,
An AC input module connected to a traffic signal to provide AC power;
A pedestrian signal display module that receives whether a light corresponding to red, yellow, or green lights of the traffic light is turned on; And
It includes a status display module for indicating whether the guide system is operating normally or not, and
The AC input module, the pedestrian signal display module and the status display module is a guide system detachably mounted to the main board.
