Abstract

The embodiment of the invention discloses torque measuring equipment. The equipment comprises a wireless power supply device, a voltage conversion device, an analog-to-digital conversion device, a single chip microcomputer and a wireless data sending device; the wireless power supply device is connected with the voltage conversion device; the voltage conversion device comprises a first voltage conversion module, a second voltage conversion module and a third voltage conversion module; the analog-to-digital conversion device comprises an interface connected with a second voltage output end of the second voltage conversion module and a stress sensor; an interface connected with the stress sensor is connected with an analog-to-digital converter ISL28533; a single-ended output pin of the analog-to-digital converter is connected with a single-chip microcomputer and is used for sending the processed data to the single-chip microcomputer; the interface connected with the stress sensor is usedfor sending the voltage difference generated by a strain gauge to the analog-to-digital converter; and the single-chip microcomputer is used for sending the data to a wireless data sending device. Byapplying the scheme provided by the embodiment of the invention, the torque measurement efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of torque measurement, in particular to a torque measurement device. Background technique [0002] With the development of the domestic automobile industry, new models emerge in an endless stream, and automobile bench and road tests are becoming more and more important. Modern engines need to increase the speed to improve mechanical performance and efficiency, and torque is an important indicator of motor and engine performance, so high-precision and reliable torque measurement is required. [0003] The existing torque measurement methods mainly include the transmission measurement method of the resistance strain gauge type. The torque will cause a certain strain on the product to be tested, and this strain is proportional to the magnitude of the torque, so the corresponding torque can be detected through the resistance strain gauge that will undergo torsional deformation. When the product to be tested is ...
