State inspection system and state inspection method

Abstract

The invention discloses a state inspection system, which is applied to weft knitting machines. The state inspection system comprises a driver module; an ARM processor module; a serial transceiver module; a drive detection module; a tool bit action detection module used for detecting vibration signals generated in the work of the tool bit and converting the vibration signals into second voltage signals; a comparison signals control module used for receiving PWM signals from an ARM processor and converting the PWM signals into third voltage signals; and a comparison circuit module used for receiving the second voltage signals from the tool bit action detection module and the third voltage signals from the comparison signals control module, comparing the second voltage signals and the third voltage signals, and sending a comparison result to the ARM processor module. The state inspection system and a state inspection method have the advantages that the state inspection system further improves the efficiency of state inspections through a double closed-loop state detection.

Description

technical field [0001] The invention relates to a state detection system and a state detection method. Background technique [0002] Most of the needle selector control systems of weft knitting machines in the market are open-loop controlled. When the needle selector drive circuit is damaged, or the needle selector cutter head and the mechanical parts of the housing are abnormal or damaged, the needle selector control system cannot detect In this state, the circular weft knitting machine is still in the knitting state, which will cause the cutter head of the needle selector to not move in place, or the cutter head will not be able to maintain its strength. As a result, the needle output of the knitting machine is abnormal, resulting in fabric defects. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a state detection system and a state detection method to solve the above problems. [0004] In order to ...
