Speed test system and test method

Abstract

The invention belongs to the technical field of speed test and relates to a speed test system and test method. The system comprises a marking module for marking a target object, an acquisition modulefor acquiring the image of the target object and recording the acquisition time of the image, a speed module for calculating the speed of the target object during the movement of the target object, and an output module for outputting a result; the marking module includes a fixing member for connecting the target object, a light emitting tube arranged on the fixing member, and a driving circuit fordriving the light emitting tube to emit light; and the acquisition module is provided with a band pass filter. According to the speed test system and test method of the invention, a non-contact direct test speed method is adopted, so that the defects of visual estimation or test methods such as tape measures and stopwatches can be eliminated; required speed information can be calculated automatically after the image information of the target object is obtained; and therefore, the accuracy of test can be effectively improved, and a test process is efficient and convenient.

Description

technical field [0001] The invention relates to the technical field of speed measurement, in particular to a speed test system and a test method. Background technique [0002] According to the "Lifting Machinery Safety Supervision Regulations", special equipment safety technical rules and national standards, it is necessary to monitor and measure the main parameters such as the lifting speed of the crane, the running speed of the cart and the trolley, and the speed is to judge whether the hoisting machinery is modified or undergoes major maintenance. an important indicator of . [0003] At present, the number of in-use and newly-installed bridge-gate cranes is relatively large. When the factory leaves the factory, the user inspects itself or a third party detects the lifting speed of the crane and the speed of the large and small vehicles, it is often estimated based on the nameplate data and visual inspection. And simple stopwatch, tape measure etc. are determined, and the...

Problems solved by technology

[0003] At present, the number of in-use and newly-installed bridge-gate cranes is relatively large. When the factory leaves the factory, the user inspects itself or a third party detects the lifting speed of the crane and the speed of the large and small vehicles, it is often estimated based on the nameplate data and visual inspection. As well as simple stopwatches, tape measures, etc., the results obtained are inaccurate, and the detection methods are unscientific or inefficient

Therefore, the lack of hoisting machinery testing instruments and the inefficiency of testing methods have failed to effectively improve the quality and efficiency of enterprise inspection and testing, lagging behind the development of hoisting machinery testing speed technology
