Abstract

The invention provides a simple speed measuring device which comprises a first photoelectric sensor, a second photoelectric sensor, a control console and a computer, wherein the computer is connected to the control console; the control console is connected with the first photoelectric sensor and the second photoelectric sensor; light beams of the first photoelectric sensor are parallel to light beams of the second photoelectric sensor; and the light beams of the first photoelectric sensor are vertical to the movement direction of a tested object. The simple speed measuring device has the advantages of reducing the testing cost, accelerating and simplifying testing procedures and can be applied to severe environments.

Description

Technical field [0001] The invention relates to a testing device, in particular to a simple device for measuring speed. Background technique [0002] In many speed measurement experiments, it is required that the object to be measured cannot be contacted, which greatly limits the measurement method. If the method of high-speed camera is used for measurement, the cost will increase a lot, and the later data processing will be more troublesome. The test requirements are also relatively high. Summary of the invention [0003] In order to solve the problem that the coaxial electrical connector is easily assembled in the prior art and the signal transmission performance is unstable, the object of the present invention is to provide a simple device for measuring speed. [0004] According to one aspect of the present invention, there is provided a simple device for measuring speed, including a first photoelectric sensor, a second photoelectric sensor, a console, and a computer, wherein th...
