Time synchronization module KOMKON GPS

Time synchronization module KOMKON GPS (Local center F)

Time synchronization module «KOMKON GPS (Local center F)» (hereinafter GPS-module) is designed to manage traffic controllers KOMKON KDK in order to synchronize the start of the daily program work cycle with atomic clocks of artificial Earth satellite. GPS-module sends to driven controller command of cycle beginning with the number of daily programs, thus making the synchronization of controller. In the case of programs "flashing yellow" and "turn off lights" GPS-module sends a command to controller with a period of 100 seconds. With the loss of communication with the satellite GPS-module within 4 hours leads controller upon a daily program. Once every 4 hours GPS-module adjusts the internal controller clock. The control is provided by daily schedule, allowing 24 times a day to change the number of traffic management program, separable for each day of the week.

Synchronization of chain of managed by GPS-module controllers allows to organize a coordinated traffic signalization. Synchronization is carried out gradually reducing the existing difference in time between the start of work cycle at the expense of differences between minimum and normal time of basic tact, allowing the transition to the first phase of the cycle only after ending of minimal time of basic tact.

Data about the daily programs is recorded to GPS-module and controller in the same way, using external memory module KDMP.
