Based on IAP15F2K61S2 microcontroller and W5200 Ethernet control chip to achieve. W5200 cyclically monitors whether there is control information sent from the remote console, to ensure that the display of the traffic light module on the single-chip microcomputer is always the same as the display of the traffic light display module of the remote console. Realize the immediacy of remote control. The remote console uses a friendly human-machine interface, which can simulate a variety of road conditions. If it is found that the collected road condition information is abnormal, for example, a certain road is too crowded, the traffic light information can be artificially or intelligently modified to reduce the time waste caused by unreasonable timing. When an emergency vehicle appears on a road, the emergency vehicle strong pass function can be activated. The traffic light in that direction will turn to green, and the traffic light in the other direction will turn to red after two seconds of yellow for the emergency vehicle to pass. Every time the remote console changes the traffic light time information, it will send a control signal to W5200. The remote console can interact with the network through Weibo, so that the driver can know the traffic situation of the current road section and the real-time information of traffic lights in advance.
