Cubic press health monitoring method and system

The invention proposes a cubic press health monitoring method and system. The monitoring system comprises a power management module, a signal processing module and a remote control monitoring module which are serially connected. The signal processing module comprises a strain detection module, a signal conditioning module, a microprocessor, a storage module and a wireless data transmission module; the strain detection module comprises a strain collection sheet, a bridge-type compensation circuit, and an electronic switch; the signal conditioning module comprises a passage amplifier, a filter and an A/D converter; The remote control monitoring module is arranged in a remote monitoring room and acquires the test data through the wireless data transmission module. The aim of online health monitoring of cubic presses is achieved based on an electrical strain measuring method and modern wireless transmission technology. The cubic press health monitoring system can accurately acquire weak strain signal data, has the functions of online monitoring and real-time display and recording of equipment usage status, and can predicate the fatigue life of equipment in actual work conditions, thereby preventing great and malignant accidents and reducing losses.
