<p><P>PROBLEM TO BE SOLVED: To provide a remote monitoring control system by which a degree of freedom of a limit time is drastically extended only by the change of specifications of a device without changing a form of a transmission signal. <P>SOLUTION: A transmission unit 1 transmits the transmission signal with a fixed length to an operation terminal 2 having a switch SW and a control terminal 3 to which a load L is connected via a signal line Ls. The operation terminal 2 has an operation data storage part 21 which stores a set of an operation mode of the load and the limit time when the load L is controlled by limiting a time from an operation of the switch SW as operation data and an operation data transfer part 22 which transfers the content of the operation data storage part 21 to the transmission unit 1 at the operation of the switch SW. The transmission unit 1 transmits twice of transmission signals to one operation terminal 2, accepts a request from the operation terminal 2 by the first transmission signal, acquires the operation data from the operation terminal 2 by the second transmission signal and controls the load L using the acquired operation data. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
