<p>A node device is provided for a sensor data distribution system having a sensor and an external device hierarchically connected through two or more node devices. Control means (201) starts such an internal constitution component of receiving means (208) for the sensor, receiving means (206) for a data processing node, transmission means (205) for the data processing node, transmission means (207) for the external device and conversion processing means (209) as is used with constitution information held by constitution setting means (202), controls not only the connection between the started internal constitution components on the basis of an input-output relation but also the connection between the internal constitution component and the outside in accordance with connection information held by connection setting means (203), and sets the started conversion processing means (209) with the data indicating the conversion processing procedure held in conversion processing setting means (204), thereby to reconstitute a data processing node (100) into any of the node device to be connected with the sensor, the node device to be connected with the external device, and their intermediate node device.</p> |
