Traffic signal control apparatus for correction real time of standard time and method for correction of standard time

摘要

The present invention provides a traffic signal control device and a standard time correction method thereof so that interworking for traffic signal control between adjacent intersections or roads can be performed smoothly by correcting the current standard time in real time using the time information provided by the GPS. Receiving means for processing valid data received from the satellite according to a predetermined protocol, and setting and outputting a standard time valid flag in the processed data; Data processing means for receiving data processed by the receiving means in predetermined time units and temporarily storing the data processed according to a predetermined protocol among the stored data; Time information extracting means for extracting time information from the data analyzed by interpreting the data having the standard time valid flag set from the data processing means according to a predetermined protocol; Standard time correction means for real-time correcting the standard time of the traffic signal control device with the time information extracted by the time information extracting means; And a traffic signal control means for controlling a traffic signal cycle for each time zone according to the corrected time.
