The invention discloses a traffic signal lamp time service time adjusting method, and relates to the field of intelligent traffic, and the method comprises the steps: signal lamp equipment obtains a satellite time service data packet and a central time service data packet in real time in the operation process, and the satellite time service data packet and the central time service data packet comprise time service time provided by various time service modes; respectively calculating the stability magnitude P of each time service mode; when a time service deviation exists between the time service time provided by the time service mode selected by the equipment and the timing time of the local machine, determining the maximum duration allowed to be adjusted per second in the time service mode according to the corresponding P value and the time service deviation duration; and the equipment adjusts the time service time according to the maximum duration allowed to be adjusted per second, and calculates the maximum duration allowed to be adjusted per second at the next time until the time service deviation is eliminated. When the intelligent signal lamp equipment uses wireless or bus communication, precision time service can be realized among the equipment, and risks caused by time asynchronization of the signal control equipment are reduced as much as possible.
本发明公开了一种交通信号灯的授时时间调整方法,涉及智能交通领域,该方法包括:信号灯设备在运行过程中实时获取卫星授时数据包和中心授时数据包,其中包含了各类授时方式提供的授时时间;分别计算各类授时方式的稳定性量值P;当设备选择的授时方式提供的授时时间与本机计时时间存在授时偏差时,根据相应的P值和授时偏差时长确定该授时方式下每秒允许调整的最大时长;设备按照每秒允许调整的最大时长进行授时时间的调整,计算下一次每秒允许调整的最大时长直至消除授时偏差。使智能信号灯设备使用无线或总线通信时,各个设备之间可以实现精度授时,尽量降低信号控制设备由于时间不同步引起的风险。
