The invention provides an entrance and exit traffic flow detection device based on an ultrasonic radar array. The entrance and exit traffic flow detection device comprises a main control unit, an ultrasonic radar array, a communication unit and a power supply unit; the main control unit is connected with the ultrasonic radar array and the communication unit. The power supply unit is used for supplying power to the main control unit, the ultrasonic radar array and the communication unit. The main control unit is used for sending an instruction to the ultrasonic radar array; detection of vehicles entering and exiting the entrance is realized through distance detection data fed back by the ultrasonic radar array; the ultrasonic radar array comprises at least two ultrasonic radar probes whichare arranged on the side of a traffic lane and face different directions, one probe A is configured to obliquely face the vehicle driving-in direction of the traffic lane, and the other probe B is configured to obliquely face the vehicle driving-off direction of the traffic lane; the included angle between the two ultrasonic radar probes is configured to be capable of detecting the same vehicle atthe same time but incapable of detecting the same pedestrian at the same time. The traffic flow detection accuracy is high.

    本发明提供一种基于超声雷达阵列的出入口车流量检测装置,包括:主控单元、超声雷达阵列、通信单元、电源单元;所述主控单元分别与超声雷达阵列、通信单元连接,电源单元用于为主控单元、超声雷达阵列和通信单元提供电力;主控单元用于向超声雷达阵列发送指令;通过超声雷达阵列反馈的距离探测数据实现出入口进出车辆的检测;超声雷达阵列包括配置在行车道侧的至少2个朝向不同方向的超声雷达探头,其中一个探头A配置为斜向朝向行车道车辆驶入方向,另一个探头B配置为斜向朝向行车道车辆驶离方向;2个超声雷达探头之间的夹角配置为能够同时探测到同一车辆但不能同时探测到同一行人。本发明车流量检测准确率高。
