Abstract

The invention relates to a system for remote monitoring and prewarning of a fatigue state of a professional driver based on dual-card CDMA and GPRS and fiber network transmission, which belongs to the technical field of traffic safety. The system comprises an onboard wireless dual-card CDMA mobile video monitoring system, a professional driver video acquisition device, a fiber transmission system and a command monitoring prewarning system. Hardware device of the onboard wireless dual-card CDMA mobile video monitoring system consists of the dual-card CDMA, an integrative camera, an onboard display, an integrative host computer, an antenna, a control panel and an onboard GPS receiving mechanism. The professional driver video acquisition device realizes the acquisition of facial expressions of a professional driver. The command monitoring prewarning center comprises a remote monitoring host computer, monitoring management software, a video acquisition card, a monitoring and commanding large screen and the like. The system for remote monitoring and prewarning of the fatigue state aiming at driving habits and driving behaviors of the professional driver has the advantages of effectively avoiding accidents. Besides, the system has reasonable layout, convenient use and easy maintenance.

Example Embodiment

[0018] in figure 1 In, the camera on the vehicle-mounted mobile platform collects live real-time video signals and connects to the host of the CDMA trunking video transmission system through cables. The camera image is compressed by the video compression coding module of the host, and transmitted to the CDMA network through the intelligent wireless communication terminal. The video signal is transmitted to the Internet through the CDMA wireless network. The encryption function is realized by the VPDN technology, and it is connected to the remote monitoring and early warning command center of the computer network. The remote monitoring and early warning command center control server receives and controls the video images sent back from the front end and records them.
[0019] The four network decoders are connected to the video server through the local area network, and the digital video signal transmitted by the server is converted into an analog video signal, and then connected to the TV, DLP, and COMPUTER through optical fiber transmission and a matrix system.
[0020] in figure 2 In, the GPS module is used to realize the early warning of remote monitoring, and the method of short message and phone call is adopted. When the monitoring personnel of the remote monitoring center find that the driver has signs of fatigue or is in a state of fatigue, they can use a pleasant early warning method to achieve remote early warning according to the fatigue level to avoid accidents. The on-board GPS receiver receives the prompt of the short message, and has a voice to play the content of the short message, which plays a role of early warning for professional drivers.
