Abstract

The invention provides an integrated detection system. A three-dimensional combined force measuring device is provided with horizontal connection supports provided with installation through holes. The two ends of each horizontal sensor are provided with the corresponding horizontal connection supports. The horizontal sensors and the installation through holes can only be rotationally matched and connected with each other around the axes of the installation through holes, and the horizontal connection supports are fixedly connected with a table top. After the table top bears force in the vertical direction (z-axis), a stress point of the table top moves downward, but the horizontal sensors in the x-axis direction and in the y-axis direction and the installation through holes can only be rotationally matched and connected with each other around the axes of the installation through holes, so that the horizontal sensors in the x-axis and y-axis directions do not send out signals, and inter-dimension coupling is avoided. Influences of the gravity of a motor vehicle on braking force and sideslip force in the measuring process can be effectively avoided, and then the braking force of the motor vehicle is accurately measured.

Description

technical field [0001] The invention relates to the technical field of parameter measurement of public transport motor vehicles, in particular to an integrated detection system for roads. Background technique [0002] When a motor vehicle is running, it is often necessary to brake it. The force given by the vehicle brake to the motor vehicle is divided into braking force and sideslip force. The size of the braking force determines the length of the braking time of the motor vehicle. If the braking force is too small, the braking time of the motor vehicle will be too long. At this time, there may be a danger of colliding with other motor vehicles, which seriously affects the normal passage of road vehicles. Simultaneously, because the two or four driving wheels of motor vehicle are locked due to mechanical error, there may be inconsistencies in the braking between the wheels. During the driving process of the motor vehicle, once the lateral sliding force of the motor vehicle...
