The invention provides a traffic signal synchronous and asynchronous control system which comprises a traffic signal control card. The traffic signal control card comprises a control card shell, an asynchronous control mainboard, a Wi F i module, a synchronous control mainboard, a power supply, a network interface and a WiFi antenna. The asynchronous control mainboard, the WiFi module, the synchronous control mainboard and the power supply are fixedly installed in the control card shell. The power supply is electrically connected with the asynchronous control mainboard and the synchronous control mainboard, the asynchronous control mainboard and the synchronous control mainboard are electrically connected through a network interface, and the synchronous control mainboard is electrically connected with the WiFi module. In order to integrate the advantages of a synchronous control mainboard and an asynchronous control mainboard at the same time, the synchronous control mainboard and the asynchronous control mainboard are combined in one device, and a single-chip microcomputer chip is added for assistance, so that when the synchronous control mainboard is not synchronously updated in real time, and the asynchronous control mainboard calls the program originally stored in the asynchronous control mainboard through the single chip microcomputer chip for display.
本发明提供了交通信号同异步控制系统,包括:交通信号控制卡,交通信号控制卡包括:控制卡外壳、异步控制主板、Wi F i模块、同步控制主板、电源、网络接口和WiFi天线,其中所述控制卡外壳内固定安装有异步控制主板、WiFi模块、同步控制主板、电源,所述电源电性连接异步控制主板和同步控制主板,而所述异步控制主板和同步控制主板通过网络接口电性连接,所述同步控制主板电性连接WiFi模块;本发明为了能够同时兼备同步控制主板和异步控制主板优点的同时,本方案将两者合并在一个设备中,并加以单片机芯片进行辅助,在同步控制主板没有设备同步实时更新的时候,异步控制主板就会通过单片机芯片调用其内部原本存储的程序进行显示进行显示。
