Title:
DATA COLLECTION SYSTEM AND CONTROL SYSTEM USING THE SAME
Document Type and Number:
Japanese Patent JP2013255193
Kind Code:
A
Abstract:

To provide a data collection system and a control system using the same, capable of securely receiving transmitted data while reducing power consumption and communication traffic in a sensor sub-unit, by reducing the number of data transmission times from the sensor sub-unit.

A sensor sub-unit 1 includes a radio communication unit 13 for radio transmitting to a radio master unit 2 a plurality of times of measurement data including a most up-to-date measurement data, measured by a sensor unit 11, and the past measurement data, when predetermined transmission timing comes. The radio master unit 2, on receiving the transmission data from the sensor sub-unit 1 by a radio communication unit 21, transfers the received data from a wired communication unit 23 to a management server 3. The management server 3 allows a memory unit 32 to store the plurality of times of measurement data received through the radio master unit 2, in a state of being associated with each measurement time.
