<p><P>PROBLEM TO BE SOLVED: To obtain a remote monitoring device for matching the pulse integrated values of a slave station and a master station by simple configurations even when signal transmission between a slave station and a master station or between a pulse measuring instrument and a slave station is interrupted due to the maintenance of a server. <P>SOLUTION: This remote monitoring device includes: a slave station 1 equipped with a pulse measuring instrument which successively outputs pulses according to the usage of electric energy, and integrates the output pulses, and outputs a pulse integrated value; a server 100 which stores the pulses and the pulse integrated value from the slave station 1 through a signal transmission path 2, and outputs the pulses and the pulse integrated value; a master station 3 positioned so as to be separated from the slave station 1, and equipped with an output circuit 26 which successively fetches and stores the pulses and pulse integrated value stored in the server 100 through the signal transmission path 2, and displays this; and a pulse integrated value updating means 200 which reads all the digits of the pulse integrated value stored in the server 100 each time the pulses stored in the server 100 are turned to be specific values, and overwrites all the read digits of the pulse integrated value to the pulse integrated value stored in the output circuit 26 installed in the master station 3 for storage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
