Smooth expansion of a dynamic data collection system and method may be

The present invention discloses a data acquisition system and method of dynamically smooth expansion, comprising: a central data acquisition system and data collection terminal; data collection center system includes a gateway routing node, the node management data acquisition, data acquisition node, security authentication node, collecting data storage nodes, monitoring node, time synchronization service node, security certificate storage node, log management node, log storage node, the data acquisition system via a communication network with a central data collection terminal communication, said data acquisition terminal device data is collected transmitted to the data acquisition node, and transmitting the data encrypted form submission data acquisition application gateway routing node, the routing information of the data acquisition node forms a gateway routing node is returned, business reports each block transmission request to each data acquisition node initiates performed. The present invention solves the conventional high data acquisition system in the new extension applications cost, scalability is poor, the problem of security risks.
