The invention discloses a DSRC-based special signal lamp control device for a special service vehicle. The DSRC-based special signal lamp control device comprises vehicle-mounted panel display equipment and a signal lamp part. A DSRC-based special service vehicle signal lamp control method comprises the following steps of: 1, when the special service vehicle drives in, the vehicle-mounted panel display equipment communicates with the signal lamp part through DSRC wireless communication; 2, after receiving data of the vehicle-mounted panel display equipment, the signal lamp part interrupts thecontrol of the intersection annunciator over a signal lamp, and the signal lamp part autonomously controls the signal lamp; 3, the signal lamp part judges a driving direction of the special service vehicle according to the received data, turning on green light of the signal lamps in the direction, and turning on red light of the signal lamps in other directions, and the display state of the intersection signal lamps is displayed on vehicle-mounted panel display equipment; 4, after the special service vehicle drives away, the vehicle-mounted panel display equipment and the signal lamp part aredisconnected, and the intersection signal lamp is controlled by the intersection annunciator; and 5, the intersection annunciator normally provides a lamp output signal for the signal lamp.
本发明公开了一种基于DSRC的特勤车辆专用信号灯控制装置,包括车载平板显示设备和信号灯部分。一种基于DSRC的特勤车辆专用信号灯控制步骤如下:一.当有特勤车辆驶入,车载平板显示设备通过DSRC无线通讯和信号灯部分进行通讯;二.信号灯部分接收到车载平板显示设备的数据后中断路口信号机对信号灯的控制,改由信号灯部分自主控制;三.信号灯部分通过接收到的数据判断出特勤车辆行驶方向,将该方向的信号灯放行绿灯,其余方向信号灯为全红,并将路口信号灯显示状态显示在车载平板显示设备上;四.当特勤车辆驶离后车载平板显示设备和信号灯部分连接断开,路口信号灯交由路口信号机控制;五.路口信号机正常给信号灯提供灯输出信号。
