The invention discloses a traffic monitoring device capable of switching camera shooting modes; the traffic monitoring device comprises a sensor group, an infrared camera set, a visible light camera set, a visible light camera holder, an infrared camera holder, a holder driver and a digital signal processor; the sensor group comprises a pressure sensor, a photoelectric displacement sensor, and a photosensitive sensor; the infrared camera and the visible light camera gather image information, and said devices are connected with the digital signal processor as detection front ends; the holder driver can regulate the angles of the visible light camera and the infrared camera in real time. The system has a continuously working mode and an interrupted shooting mode, thus reducing the system work time, prolonging the system life, and reducing the system making cost; the system can switch shooting cameras according to the light intensity, thus protecting man eyes from having dizzy conditionsformed by visible light supplement, reducing traffic safety hidden troubles, finely adjusting camera angles, realizing blind angle-free shooting, and identifying vehicle license plates and filming violations at all weather.

The invention relates to the technical field of the detection of the traffic state of a road and particularly discloses a method for distinguishing the traffic jam of a toll plaza of a highway based on a video detection technology, which comprises the following steps: (1) shooting the video of the road of a toll plaza; (2) extracting the picture of the road of the toll plaza from the video; (3) establishing and updating a background model of the picture; (4) extracting a foreground image from the picture; and (5) obtaining the energy value and the absolute value of the variable quantity of the energy value of the foreground image and judging whether the road of the toll plaza is jammed or not. According to the method for distinguishing the traffic jam of the toll plaza of the highway based on the video detection technology, only the parameter of the energy value of the road needs to be obtained, and a jam distinguishing model is constructed, so that the judgment to the jam state of the toll plaza of the highway is finished. The algorithm is simple, the operation expense is little, the real-time property is strong, the problem of distinguishing the traffic jam of the toll plaza of the highway can be accurately and effectively solved, and a jam caution is also output at the time of jam, so that powerful information support is provided for a manager to master a site condition in time and make a management decision so as to reduce the potential safety hazard of pass in traffic.

The invention provides a vehicle-borne following vehicle distance sensing and prompting system. A mobile communication network and a system server are used to establish the binding relation and communication operation between a vehicle-borne following vehicle distance prompting signal display terminal and the mobile client used by a user, the setting of the control parameter of the vehicle-borne following vehicle distance prompting signal display terminal installed and arranged in a vehicle is carried out through the mobile client, when the vehicle-borne following vehicle distance prompting signal display terminal uses the distance sensing ability of the terminal senses and judges that a following vehicle distance is smaller than a preset limit, a vehicle distance maintaining prompting signal display operation is executed, the condition of a too close following vehicle distance can be sensed and prompted, thus the relief of the 'road rage' mood of drivers between driving vehicles is helped, the traffic hidden risk brought by a too close distance between vehicles is reduced, the system is convenient to use by a user, the functions are diversified, the technology realization difficulty is small, the application effect is remarkable, and the system has a good market application prospect.

The invention discloses an intelligent robot system for motor vehicle driver training. The intelligent robot system comprises an industry supervision platform, a public service platform and a training intelligent robot. Data interaction is performed through a wireless network, so that supervision, on-line examination and approval, intelligent teaching, a mock examination and process analysis are performed on the driver training industry. Working efficiency of a driver training industry department in charge is improved, teaching cost of a driving school is reduced, the training teaching process is standardized, teaching quality is improved, learning efficiency of learners can be rapidly improved, safety in the training process is improved, and a teaching program is implemented. In this way, potential traffic dangers are reduced, and social and public life and property safety is guaranteed.
