The invention relates to an intersection traffic comprehensive control system, wherein a statistical module is used to generate vehicle flow data of each traffic lane and each direction, a traffic light intelligent control module is used to generate vehicle stopping and queuing data of corresponding traffic lanes and directions, a vehicle speed detecting module is used to generate vehicle speed data, a snapshot control module is used to generate a snapshot control signal, a traffic light control module is used to receive each traffic light control instruction of a central processing module and to connect or disconnect a corresponding traffic light power supply circuit, the central processing module is used to receive information and data which is sent by other modules and devices and to control other modules and devices. The intersection traffic comprehensive control system has various control functions of monitoring the traffic conditions, controlling the traffic lights and shooting violation vehicles and the like, the functions of the system and the various devices which are controlled by the system are effectively exerted, the system structure is simplified, the investment is saved, and the system building and using are convenient.

The invention relates to an intelligent traffic light control system, which comprises a microprocessor which is used to control switching actions of traffic lights, wherein the microprocessor is provided with a manual input device, a forced switching device and an intelligent detecting device, wherein the intelligent detecting device comprises a panoramic camera and an intelligent controller, the panoramic camera is used to obtain real time video images of road conditions on each direction, the intelligent controller is used to adopt the video images which are obtained by the camera through a video capture card and to recognize stopping vehicles on each road, the stopping and queuing distance of the vehicles is calculated, recognition and calculation are carried out according to the stopping and queuing distance of the vehicles on each road, an instruction of modifying a traffic light control parameter is sent by the microprocessor according to prearranged procedures, and the microprocessor receives the instruction and modifies the traffic light control parameter. The control system automatically adjusts the traffic light control parameter according to the traffic flow changes on different directions to improve the traffic efficiency of intersections and to realize optimum control to intersection traffic.

An EGR cooler having an inlet / outlet tube installed by insertion is provided, and can have a curved gas flow path defined at least in part by a tank body. The inlet / outlet tube can include a first inlet / outlet tube and a second inlet / outlet tube to introduce and to exhaust gas. The tank body can have a configuration such that a connection housing is installed to establish fluid communication between individual ends of both the first inlet / outlet tube and second inlet / outlet tube, so that heat exchange efficiency between the inflow gas and the cooling fluid can be improved, and effective space utilization can be promoted in equipping an vehicle with the EGR cooler.

The invention relates to a method for carrying out a lane change in a motor vehicle (4), wherein a change from a lane (2) which is currently being travelled on by the motor vehicle (4) in question to an adjacent lane (3) is carried out autonomously if a recommendation to change the lane (2, 3) is output by a control device. The recommendation to change from a relatively fast lane (2) to a slower lane (3) is output by the control device if - a lane change is possible without putting at risk the motor vehicle (4) in question and / or a motor vehicle travelling on the slower lane (5, 6), - on the lane (2) which is currently being travelled on the motor vehicle (4) in question is not being prevented from travelling at a speed predefined for the motor vehicle (4) in question by another motor vehicle (8) travelling ahead, and - on the slower lane (3) no motor vehicle which is travelling at a higher speed than the speed of the motor vehicle (4) in question is detected at a specific distance behind the motor vehicle (4) in question.

The invention relates to a method for large diameter borehole extracting and high-pressure grouting hole sealing, which is characterized in that the method comprises the following steps: at the coal seam top and in the floor roadway rock surface, an across-seam hole drilling and sealing section are constructed in the coal seam; a hole sealing pipe is positioned into the hole sealing stage; a grouting cavity is reserved between the hole sealing pipe and the hole wall of a borehole; a grouting pipe and a return pipe are respectively arranged in the two positions corresponding to the grouting cavity; the output pipe of a high pressure grouting pump communicates with the grouting pipe; grouting material is infused into the grouting cavity by the high pressure grouting pump through the grouting pipe, until the grouting material overflows out of the return pipe; the hole sealing section is formed through maintenance; across-seam hole drilling is constructed in the inner cavity of the hole sealing pipe. The method has the advantages that the hole sealing effect is good, the effective gas extraction time is long, and the construction method is simple.

The invention relates to a magnetic energy oil-saving environment-friendly device for magnetizing fuel oil. The device comprises an oil pipe body, a plurality of magnetizers and a magnetic filter, wherein the plurality of magnetizers are arranged on the outer diameter of the oil pipe body; each magnetizer is internally provided with two permanent magnet bodies which are arranged in symmetry centered on an axial center; a yoke iron ring encircles the outer diameters of the two permanent magnet bodies; an interval is formed between every two adjacent magnetizers; the permanent magnet bodies in each magnetizer are distributed at equal angles; the magnetic filter is provided with a filtering net in a passage through which the fuel oil flows; and the filtering net is internally provided with a permanent magnet core. The device has the following beneficial effects that the magnetic field intensity of the whole section through which the fuel oil flowing in the magnetic energy oil-saving environment-friendly device is raised, the magnetizing capability of the fuel oil is enhanced, and the burning efficiency of the fuel oil is raised remarkably; and ferromagnetic impurities in the fuel oil are prevented from entering an oil path in a magnetizing area by the filter, so that the fault of oil path blockage is avoided.
