6. alarm function for automotive embedded host with alarm input interface, you can connect any kind of regular alarm device.

When the alarm occurs, the alert information is remote to the monitoring center in monitoring center of GIS maps the vehicle will the corresponding icon flashing, supervisory personnel using the mouse to click the icon corresponding to the vehicle, the vehicle information (such as license plate numbers, driving directions, etc) and driver information (such as name, age, driving experience, etc.) are automatically displayed, and the vehicle will the corresponding video signal through GPRS or CDMA transmission to the monitoring center, monitor staff for immediate on the car for remote monitoring. Combined with GPS and digital map, police can immediately understand the location of the vehicle, this exhibition rapidly.

Transport vehicle monitoring system

The system consists of three major components: vehicle monitoring systems, data and video transmission system (CDMA/GPRS/GPS), the Center control and management system (see picture).

1. vehicle monitoring system

Vehicle monitoring system installed in the dangerous goods transport vehicles, the main function for vehicle operation monitoring, video and wireless data transfer.

This programme in dangerous goods transport vehicles, the installation of 2 ~ 4 infrared color (or black and white) pinhole camera, mounted in the cab and the rear part, even in the absence of any illumination night, also see site cannot be guaranteed.

Due to the dangerous goods transport vehicles is mobile and changes of temperature, humidity, dust, working conditions, the requirements of the digital video recorder.

This programme uses the on-board embedded hard disk video production company in Tianjin world weiye TC-2800A ofN series-mounted on-board embedded host, the host uses the Embedded RTOS operating system, system stability, extend powerful characteristics. Chassis design professional shockproof, multiple protection for a hard drive; speed, driving directions, traffic status and real-time image recording function; excessive speed warning function, you can record the speed, steering, brake and stop time, and other related travel information. Video data is stored using H.264 compression, has a clear image, small footprint, and network bandwidth consumption is small, and many other features.

Other automobile electrical equipment more voltage variations relatively large, relatively strong electromagnetic interference, the on-board embedded host with a wide input voltage range of power.

The input voltage is within the scope of the DC7V-30V, output voltage can be maintained, through the power supply to the monitor and camera power supply, can make the host image in auto standby and moving to keep clear and stable, so that you can increase the life of the monitor and camera and always stable image.

2. data transmission system

In addition to this vehicle monitoring and video recording, with the use of wireless digital transmission module, this system can also be car audio and video related travel information through GPRS or CDMA module real-time transmission to the monitoring center, dangerous goods transport vehicles, remote audio and video monitoring.

3. central monitoring and management system
