Programmable portable type rotating speed and torque measuring device

The utility model relates to a programmable portable type rotating speed and torque measuring device. After a rotating speed and torque signal output by a photoelectric coder is filtered and shaped by a photoelectric isolation circuit, the rotating speed and torque signal is output to a data collection card; and the signal collected by the data collection card is processed by an embedded type personal computer (PC), and the rotating speed, the torque and the output power value on a shaft are calculated and are transmitted onto a display of a touch screen for real-time displaying. The device is simple and convenient, is easy to carry, has good measuring accuracy and is reliable to operate; the waveforms and the numerical values of the rotating speeds and the torques, which are output by photoelectric coders with different types, can be measured, the program portability is strong, and the application range is wide; the waveforms and the numerical values of the rotating speeds and the torques of a plurality of m
