Abstract

The invention discloses a wireless transmission type motor vehicle speed measurement system and method using a pressing belt. The system comprises a plurality of sub-equipment modules and a main equipment module wirelessly connected with the plurality of sub-equipment modules, wherein the belt pressing mechanism comprises a first pressing belt and a second pressing belt, the sub-equipment module comprises a sub-shell, a sub-controller and a sub-wireless communication module, the input end of the sub-controller is connected with a first signal acquisition module and a second signal acquisitionmodule, and the main equipment module comprises a main shell, a main controller and a main wireless communication module. The method comprises the following steps: 1, arranging a belt pressing mechanism; 2, carrying out data acquisition and data processing; and 3, judging data, performing alarming and and giving a prompt. Speed measurement of the motor vehicle is achieved, the instantaneous speedof the motor vehicle at a measurement point can be accurately measured, data transmission is conducted in a wireless transmission mode, the test system is convenient to build and convenient to operate, and test data are accurately obtained.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle speed measurement, and in particular relates to a wireless transmission type motor vehicle speed measurement system and a speed measurement method using a pressure belt. Background technique [0002] As a means of transportation, motor vehicles are frequently used in daily life. The state requires testing agencies to test the noise of motor vehicles and other aspects. During the testing process of these items, it is necessary to test the speed of motor vehicles passing through specific points. For example, in motorcycle noise testing, it is stipulated that the instantaneous vehicle speed passing the test road entry point must be within ±3% of the specified vehicle speed. However, currently widely used speed measurement devices, such as GPS speedometers, cannot accurately record the instantaneous speed of motorcycles passing through specified points, and can only rely on the driver to visuall...
