Abstract

PROBLEM TO BE SOLVED: To enable more devices to share data without requiring a server by transmitting communication data that a receiving terminal has received all together at constant intervals of time to respective devices connected to a LAN(local area network), i.e., communication terminals, etc., which receive monitor data. SOLUTION: Monitor signals as communication signals sent by controlled terminals 1 and 6 are passed through modems 2 and 7 and communication lines 3 and 8, decoded by modems 4 and 9, received by communication terminals 5 and 10, and transmitted to control terminals 13 and 14 through the bus 11 of the LAN. A transmission format passed through the LAN bus 11 consists of a header part, a transmission destination address part, a, data part, etc., and the communication terminals 5 and 10 transmit the received communication data all together to the control terminals 13 and 14 connected to the bus 11 of the LAN at constant intervals of' time. Consequently, equipment such as a server is not necessary, and information from the controlled terminals can be shared at constant intervals of time without increasing communication data.

According to the present invention, a receiving terminal transmits received data at regular intervals using a simultaneous transmission mode of a LAN, so that all the LAN terminals share the data. Here, the simultaneous transmission mode is different from the one in which the address of a transmission destination is normally added to transmission data and one-to-one data communication is performed with the transmission destination, in the above-described LAN system. By adding a specific address, all the LAN terminals connected on the LAN
Reception is possible. When all the received data is transmitted at once, the terminal on the receiving LAN has a lot of unnecessary data, which may result in useless communication.

[0006] In the remote control monitoring device, the control terminal and the controlled terminal are connected one to one. However, other terminals are connected on a one-to-one basis and do not need all of the data to be transmitted and received. Therefore, by simultaneously transmitting the current reception data at regular intervals, the monitoring data can be shared without transmitting useless data.
