<p>PROBLEM TO BE SOLVED: To provide a monitoring control system which executes data transmission without data error. SOLUTION: The monitoring control system has a detection-signal relay means comprising AI nodes A11-A31, which output analogue signals derived from sensors S10-S31 measuring electrical quantities of on-site devices distributed and installed in substations or the like, upon A/D converting, to a wireless local area network, as detected signal data; and a CPU device 3 which receives the detected signal data from the wireless local area network, and executes process for monitoring control.</p> |
