Asynchronous process data collection system and data collection method

Abstract

The utility model discloses an asynchronous process data collection system and the method of realizing the process data collection. The utility model adopts supporting data packet communication to provide the network of process data communication service with high speed and large scale; connected with the network, the utility model is used to provide active real-time data collection terminal of active real-time process data collection service; connected with the networks, the utility model is used to provide passive idle general computer system of process data filing service; the incentive of the asynchronous process data collection system comes from the process, and the network and the general computer system are a passive idle system. The process data collection method comprises: establishing process data queues; conducting process data queue compacting and transmitting by data collection terminal; and finally conducting process data queue reduction. The utility model evades the uncertainty of Ethernet communication and the non-real time of the general computer system effectively, and improves the real time and stability of the process data collection system greatly.
