Abstract

The invention discloses a photoelectric sensing system applied to rotation speed measurement. The system comprises a photoelectric sensor, a motor to be measured, a power supply module and a supporting base; the power supply module is in bidirectional connection with the photoelectric sensor, a display unit and the motor to be measured through wires; and the photoelectric sensor is in bidirectional connection with the display unit through a wireless transmit-receive module. The invention belongs to the technical field of rotation speed measurement. According to the photoelectric sensing systemapplied to the rotation speed measurement, the optical fiber sensor is adopted as a measuring main body; the short testing time of the optical fiber sensor is short; and the optical fiber sensor doesnot need to be in direct contact with the object to be measured, and has high stability. The test time of an existing optical sensor is long; if the existing optical sensor is used for rotation speedmeasurement, the measurement limit of the existing optical sensor is low; the existing optical sensor is only applicable to some motors, and fails to realize measurement for some special motors; andexisting optical sensing equipment has low stability and needs to be in actual physical contact with a object to be measured during measurement, and as a result, measurement deviation will be broughtabout easily. With the photoelectric sensing system of the invention adopted, the above problems can be solved.

Description

technical field [0001] The invention relates to the technical field related to rotational speed measurement, in particular to a photoelectric sensor system applied to rotational speed measurement. Background technique [0002] Many aspects of life and production require accurate measurement of speed, especially in terms of rotational speed. For all rotating machinery, it is necessary to monitor the rotational speed of the rotating mechanical shaft. The rotational speed is an important indicator of the normal operation of the machine. For example, people Most of the electricity used in daily life is generated by generators. At this time, we must know the speed of the generator in order to control it and output a stable voltage. Otherwise, it will bring a lot of inconvenience to our life and production. For example, the speed of the speed is closely related to the precise dosage of the gear pump. Therefore, accurate measurement of rotational speed is of great significance to ...
