A vehicle guide system for guiding vehicles, the system comprising:
- solar guide lamps including a solar cell, a capacitor for charging electric power stored by the solar cell, LED modules for emitting light of multiple colors, and a control device for controlling on and off of the LED modules, and installed to be buried in a road surface at regular intervals;
- and
- a controller for receiving lighting cycle information including a lighting color and a lighting cycle from outside, wherein
- the control device further includes:
- a wireless communication module for receiving the lighting cycle information from the controller;
- a lighting-on-off control module for controlling the LED modules according to the lighting cycle information received from the controller through the wireless communication module;
- and
- a control module for activating the wireless communication module to operate only during a preset communication cycle T, and deactivating the wireless communication module to stop the operation when a threshold time is elapsed, and
- the control device further includes a communication error information generation module for generating communication error information when wireless communication with the controller is not performed for a preset number of times (TH:
- Threshold), wherein
- when the communication error information is generated by the communication error information generation module, the control device controls the wireless communication module to transmit the communication error information to the controller, and
- when the communication error information is received from the control device, the controller re-sets the communication cycle T, and transmits the re-set communication cycle T to the control devices of the solar guide lamps, and
- the control device performs wireless communication according to the re-set communication cycle T received from the controller, and
- the control device further includes a deactivation information generation module, and
- the deactivation information generation module further includes:
- a charged electric power detection module for detecting charged electric power of the capacitor;
- a comparison module for comparing the charged electric power detected by the charged electric power detection module with a preset threshold value;
- and
- a generation module for generating, when the charged electric power is determined to be lower than the threshold value by the comparison module, deactivation information indicating that wireless communication with the controller is not performed, and
- when the deactivation information is generated by the deactivation information generation module, the control module of the control device transmits the generated deactivation information to the controller not to drive the wireless communication module,
- wherein the system further comprises an external server for transmitting a preset operation processing value, wherein the controller sets in advance and stores matching information on matching color and cycle information of each solar guide lamp according to the operation processing value received from the external server, and generates, when the operation processing value is received from the external server, the lighting cycle information according to the received operation processing value using the matching information.
