Abstract

The system comprises: the module for collection of signals from sensor, the signal process module, the performance prediction module, the wireless communication module and the sever. The module for collection of signal from sensor takes charge of collecting signals from multi-path sensor. The signal process module analyzes the signals from sensor and extracts the feature of time-domain or frequency-domain. The performance prediction module first uses the principle component analysis method to extract the feature vector presenting the performance of large format color inkjet printer, then uses neural net method to make data fusion of the feature vector, and to predict and recognize the state of the large format color inkjet printer. The wireless communication module sends the data information to the database in the server by using GPRS wireless transmission mode.
