Abstract

PURPOSE:To decrease the faults of noises, etc., without providing many optical communication equipments to a monitor center building by forming a communication network to perform the loop transmission of information where the information are successively transmitted to the receivers of adjacent buildings to be monitored and finally returned to the receiver of a terminal center equipment. CONSTITUTION:The information received from a terminal center equipment TCS of a monitor center building A is sent to a receiver R1 of an adjacent building B to be monitored via an optical transmitter T connected to the equipment TCS and then to a transmitter T1 from the receiver R1 via a terminal equipment TS1. Furthermore the information is transmitted to a receiver R2 of another adjacent building C to be monitored from the transmitter T1 and finally returned to a receiver R connected to the equipment TCS of the building A in a loop. Thus only a pair of transmission/reception devices suffices to the equipment T of the equipment TCS and at the same time the transfer of information is attained between the buildings adjacent to each other. Then the faults of noises, etc., are decreased.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a building remote monitoring device using an optical communication device.

[Conventional technology]

Generally, when a terminal device installed in a monitored building and a terminal device installed in a monitoring center building are connected, they are connected by electric wires.

In the case of the above-mentioned connection, if there is an obstacle in the connection route due to roads, etc., the wires are buried underground or connected using utility poles, etc., which causes problems such as the connection distance becomes long and the connection route becomes complicated. there were.

For this reason, recently, as described in Japanese Unexamined Patent Publication No. 121551/1983, optical communication equipment has been installed in the terminal equipment of the monitored building and the terminal center equipment of the monitoring center building, and the connection is made using optical signals. is proposed.

[Problem to be solved by the invention]

In the above conventional technology, since the transmitting device and the receiving device in the optical communication device are integrated, when monitoring multiple monitored buildings, for example, when monitoring four monitored buildings, four monitored buildings are installed in the monitoring center building. If a building is equipped with optical communication equipment, as many optical communication equipment as the number of buildings to be monitored will be required. Furthermore, if the monitored building and the monitoring center building are far apart, there is a problem that disturbances such as noise may occur.

An object of the present invention is to provide a building remote monitoring device that does not require the provision of many optical communication devices in a monitoring center building and can reduce disturbances such as noise.

[Means to solve the problem]

In order to achieve the above objective, each of the multiple monitored buildings is equipped with a terminal device that monitors the equipment in each building, and information from this terminal device is sent to the monitoring center building via the optical communication device on the monitored building side. In a building remote monitoring device that transmits data to a center-side optical communication device of a terminal center device installed,
Each of the monitored building-side optical communication devices is divided into a transmitting device and a receiving device and connected to a building-side terminal device and a terminal center device, and a transmission device connected to a terminal center device provided in the monitoring center building. The information from the device is sequentially transmitted to the receiving device of the adjacent monitored building, and then from the transmitting device of this adjacent monitored building to the receiving device of other adjacent monitored buildings, and finally to the terminal center device. A communication network is configured to perform loop transmission back to the receiving device.

[Effect]

Information from a terminal center device installed in a monitoring center building is transmitted via an optical transmitter connected to this terminal center device to a receiving device in an adjacent monitored building, and from this receiving device via a terminal device. sent to the device. Furthermore,
The information is sequentially transmitted from this transmitting device to receiving devices in other adjacent buildings to be monitored, and is finally loop-transmitted back to the receiving device connected to the terminal center device in the monitoring center building.

As a result, the optical communication device of the terminal center equipment needs only a pair of transmitting/receiving devices, and information can be exchanged between adjacent buildings, reducing interference such as noise.
