Method for real-time monitoring of torque state of calibration platform

Abstract

The invention relates to a method for real-time monitoring of the torque state of a calibration platform. The method relates to a power measuring device and a torque displaying instrument located in a control cabinet of a platform testing system, wherein the power measuring device acquires torque values through a torque sensor, the torque values acquired by the torque sensor are displayed and output through the torque displaying instrument, the output end of the torque sensor is connected with a monitoring instrument through a shield cable by means of a current input connecting method, and the torque monitoring state is determined by comparing the torque values displayed and output by the monitoring instrument with the torque values displayed and output by the torque displaying instrument. According to the method, displaying through the monitoring instrument and displaying through the torque displaying instrument are conducted at the same time, comparison and judgment of any torque points can be achieved, and then real-time monitoring is achieved; the judging method is more scientific, more evidence-based, visualized, convenient and apparent to the eye, as a result, waste of time and labor cost caused by misjudgment are greatly reduced, calibration quality is guaranteed more effectively, and the credibility of a calibration result is improved.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a method for real-time monitoring of the torque state of a school bus platform, belonging to the technical field of school bus monitoring. Background technique [0002] The school bus station is one of the most important equipment for diesel engine performance testing, because it is used frequently and under harsh conditions. In any inspection, it was found that the torque value of the dynamometer in the school bus station would fluctuate and deviate every day, which is also consistent with the actual daily application for metering services at the school bus station. At present, due to technical limitations, the school bus station can only conduct spot checks on the zero position of the dynamometer, and this kind of torque value fluctuation can only be detected by the operator's feeling during use, which is an after-the-fact type, so there is a quality risk. Manual calibration before each ...

Problems solved by technology

[0004] The disadvantages of the above-mentioned torque value fluctuation error judgment method are: except for the intuitive and convenient spot check of the torque zero position indication value, other judgment methods have no effective judgment basis, human subjective consciousness and experience dominate, and it is easy to make wrong judgments and blindness. Calibrating the dynamometer not only wastes time and delays production but also increases labor costs
