车辆内部藏匿人的时候，仅仅对藏匿者的肢体、心肺等动目标回波进行检测显示，从而实现探测的目的。它的工作原理是基于人体运动在雷达回波上产生的时域多普勒效应来进行分析判断有无生命体存在以及生命体得具体位置信息。它充分利用纳秒级电磁波脉冲的频谱宽、穿透性强、分辨力高、抗干扰性好、功耗低等特性。

When a person is hidden inside the vehicle, only the hidden person's limbs, heart and lungs and other moving target echoes are detected and displayed, so as to achieve the purpose of detection. Its working principle is based on the time domain Doppler effect generated by human motion on the radar echo to analyze the presence or absence of life forms and the specific location information of life forms. It makes full use of the nanosecond electromagnetic pulse of the broad spectrum, strong penetration, high resolution, good anti-interference, low power consumption and other characteristics.

       雷达的生命侦测仪可以在30秒内侦测出一定范围内遇险者的移动和呼吸，可以穿透障碍物(例如钢筋混凝土砖墙，柏油层，车辆钢板)进行侦测，不受声音和背景噪音的影响。传感器可以发出包含目标指定信息的信号，从而使侦测活动更快，更精确。

The radar's life detectors can detect the movement and breathing of a person in distress within a range of 30 seconds and can penetrate obstacles (e.g., reinforced concrete brick walls, asphalt layers, vehicle steel plates) for detection independent of sound and background noise. The sensor can send signals containing target-specific information, thus making detection activities faster and more accurate.

通过传感器对车辆进行AB门多前端系统联动(选配)

      本系统集成了身份证读卡器，车牌识别摄像机（2台，进车方向和出车方向各一台），全景摄像机，车底检测系统以及生命探测仪系统的相关信息，实现车辆进、出过程中对驾驶员以及车辆本身的全方位监控，自动化管理，信息记录。

This system integrates ID card reader, license plate recognition camera (2 units, one each in the direction of entry and exit), panoramic camera, undercarriage detection system and information related to the life detector system to achieve all-round monitoring of the driver and the vehicle itself during the entry and exit of the vehicle, automated management and information recording.

    其中身份证读卡器用以自动识别和记录驾驶员的身份信息，车牌识别摄像机用以自动识别记录车牌信息，全景摄像机用以记录整个车辆进出口的全景图像，车底检测系统用以检测车辆底部的情况，并形成图片信息保存，车辆探测仪用以探测车辆内部是否有人员藏匿。

The ID card reader is used to automatically identify and record the driver's identity information, the license plate recognition camera is used to automatically identify and record the license plate information, the panoramic camera is used to record the panoramic image of the entire vehicle import and export, the underbody detection system is used to detect the bottom of the vehicle and form the picture information to save, and the vehicle detector is used to detect whether there are people hiding inside the vehicle.

    可在每个监区的车辆进出口的管理站内配置一台工作电脑（根据系统容量可加配一台服务器），安装相应软件系统，通过串行接口、USB接口或IP接口，将工作电脑和上述多个系统连接，通过专业的开发的车辆通行管理信息系统，实现对出入口车辆的检测和管理。通过这套系统可以极大地实现对车辆进出口的有效管理，提高管理人员的工作效率，有效预防犯罪。 

A working computer can be configured in the management station of vehicle import and export of each prison area (a server can be added according to the capacity of the system), the corresponding software system can be installed, and the working computer can be connected with the above multiple systems through serial interface, USB interface or IP interface to realize the detection and management of vehicles at the entrance and exit through the professionally developed vehicle passage management information system. Through this system can greatly realize the effective management of vehicle import and export, improve the efficiency of management personnel and effectively prevent crime.
