Problems solved by technology
[0006] In view of the need for long-term monitoring of the rotating shaft of the current long-time working equipment, it is necessary to solve the problem that the battery life is insufficient and cannot be used for a long time under the premise that the strain monitoring device cannot be replaced frequently. The present invention proposes a self-generating rotating shaft The shaft strain monitoring device and system can generate electricity by itself through the rotation of the shaft system, provide long-term strain monitoring functions without regular maintenance, and provide an effective solution for the current bottleneck of rotating shaft strain monitoring

The invention provides a self-generating rotating shaft strain monitoring device and system. The device comprises a strain gauge unit which is installed at a dangerous cross section of a rotating shaft, and is used for measuring the strain amount of the rotating shaft; an acquisition module connected with the strain gauge unit and used for acquiring a strain signal from the strain gauge unit; a self-correction module connected with the acquisition module and used for correcting the strain signal; the signal transmitting module is connected with the self-correction module and is used for transmitting the corrected strain signal to processing equipment to realize strain monitoring; a self-generating module connected with the power supply module and used for generating electric energy in the rotating shaft operation process and transmitting the electric energy to the power supply module; and the power supply module connected with the acquisition module, the self-correction module and the signal transmitting module, and used for storing the electric energy generated by the self-power-generation module and providing the electric energy for the acquisition module, the self-correction module and the signal transmitting module. The technical problem that an existing strain testing device cannot work for a long time is effectively solved.
Description
technical field [0001] The invention relates to the technical field of long-term monitoring of rotating mechanisms, in particular to a self-generating rotating shaft strain monitoring device and system. Background technique [0002] The rotating shaft is one of the key transmission mechanisms of most rotating equipment. Its operation stability has an important impact on the equipment. As the main component of the rotating equipment, the rotating shaft undertakes all the power transmission of the equipment. For equipment that needs to work for a long time, the construction period of this type of equipment is generally tight. During the use of the equipment, if there is no failure, it will work continuously for 24 hours. [0003] Since the rotating shaft mechanism of the long-time working equipment cannot be replaced and repaired regularly, it can only be repaired when it breaks down. As a result, the rotating shaft cannot be found and repaired in time before the fault occurs,...
