The invention discloses an intelligent video monitor of railway crossing, which includes a video sensor that is arranged on the railway crossing and is capable of covering the traffic condition of the entire crossing as well as a monitoring computer that is used for monitoring the condition of the entire crossing and is capable of dynamic image understanding; wherein, the monitoring computer includes a video image collecting module, a displaying unit, an image pretreatment module, a railway crossing customizing module, a dynamic image understanding module used for analyzing the safety condition of the crossing, a video information saving module, a crossing wireless receiving and transmitting module and an issuing module of crossing safety information; wherein, the issuing module of crossing safety information is connected with a crossing displaying unit and an alarming sound playing unit; and the monitoring computer is connected with the wireless receiving and transmitting device. Theinvention has a high intelligence level and is capable of automatically judging various dangerous conditions or failures of the crossing through the image understanding technique and is also capable of mutual communication between the train driver and safety condition of the crossing as well as between the passengers and vehicles passing through the crossing and the train running condition through the wireless communication technique.

The invention discloses an urgency arresting gear used under the condition of automobile braking system failure. The urgency arresting gear comprises an arresting hook system, an arresting machine system, a tail hook component, a movable shaft, a hook arm and a tail hook, wherein the arresting hook system is fixed to an automotive chassis and comprises a tail hook component and a hoist component; the arresting machine system is arranged on a road and can arrest the arresting hook system; the tail hook component comprises a supporting seat arranged at the bottom of the automobile chassis; the movable shaft is movably arranged on the supporting seat; one end of the hook arm is connected with the movable shaft though a transverse centering damper; the tail hook is connected with the other end of the hook arm, and the hoist component drives the hook arm to enable the tail hook to be extended and retracted. By means of the urgency arresting gear, a runaway automobile is effectively arrested in the safe range, and the runaway automobile is prevented from running at high speed on an expressway for a long time or falling off a cliff on a downgrade section.

The invention relates to a device for preventing faulty operation for using an accelerator as a brake by mistake based on computer vision, which comprises a vision sensor, an embedded system, a vehicle speed measuring unit, a vehicle driving angle measuring unit, a distance measuring unit, a voice alarm unit, an accelerator control unit, a brake control unit and a power supply unit, wherein the embedded system is used for reading the information of driving speed of a vehicle, a vehicle steering wheel angle, a video image of a front road of the vehicle, and the like, estimating a barrier distance on the front road and calculating a driving risk factor and driving risk change tendency according to the barrier distance, the vehicle steering wheel angle and the speed of the vehicle. The invention makes a corresponding driving decision according to the driving risk factor and the driving risk change tendency, controls the voice alarm unit to produce drive warning sound according to the driving decision, controls the accelerator control unit to allow the action effectiveness of stepping the accelerator by a driver and controls the brake control unit to control the automatic brake of thevehicle.

The invention belongs to the technical field of digitalized monitoring and management of vehicles, and in particular relates to a digitalized vehicle overspeed and fatigue driving intelligent real-time monitoring network management system. The components of the system include the automatic driving recorder installed on the car; the radio frequency tags installed on the speed limit signs of highways and urban roads; Digital information reader for driving and other violation information data; portable mobile information terminal carried by police officers to send and receive vehicle speeding, fatigue driving and other violation information data; realize interactive transmission of information with digital information reader and portable mobile information terminal and information processing monitoring computer systems. This system can effectively improve the law enforcement efficiency and ability of the traffic management department, avoid omissions and mistakes in the management work, eliminate the phenomenon of vehicle speeding and fatigue driving, and improve the level of road traffic management and the image of the city.

Disclosed is a mis-tread preventing device for emergency stop, belong to autocontrol technical field. The input port of a signal processor is connected to the output port of pressure difference electrical signal of a controllable magnet valve; the output port of the signal processor is connected to the input port of a controller; the two output ports of the controller are connected to the control pole of two electronic switches; the anode and the cathode of the first electronic switch are connected in series in a DC power supply loop for the controllable magnet valve; the controllable magnet valve is disposed at the upper range of the foot pedal accelerograph in a gasoline pipe of the automobile. Gasoline supplied to the automobile first goes through the controllable magnet valve, then passes the foot pedal accelerograph and at last goes to the cylinder of the engine. The anode and the cathode of the second electronic switch are connected in series in a DC power supply loop for an electricity powered handspike; the top of the electricity powered handspike is mechanically connected to the force arm at the lower part of the pedal rod of an arrester in a mode that the handspike and the arrester can rotate in a plane within 90 degree. The invention can prevent accidents and safeguard the safety of people as well as transportation vehicles.
