Problems solved by technology

[0006] However, prior art building management systems have at least the following problems: If the watt-hour meter 140 is directly connected to the BAC network gateway 120, the watt-hour meter 140 must be installed in the Near BAC Network Gateway 120
[0007] In addition, although a BAC network module could be installed between the watt-hour meter 140 and the BAC network gateway 120 to allow the watt-hour meter 140 to be installed remotely from the BAC network gateway 120, this would increase the cost of the installation and impose a burden on the workers who do so. come unchanged

Abstract

The invention discloses a building management system, which comprises: a BAC network gateway, which has a protocol converter, and the protocol converter receives data in a remote communication protocol format and converts the data based on a BAC network communication protocol; a central control and a watt-hour meter that measures the wattage of the subsystem and transmits the wattage data to the protocol converter using a telecommunication protocol format.

Description

technical field [0001] The present invention relates to a building management system, and more particularly, to a building management system performing unified (centralized) control through a BAC network (Building Automation and Control Network). Background technique [0002] Recently, with the modernization of building facilities, automatic control systems are increasingly used for automatically controlling subsystems installed in buildings such as power management systems, lighting systems, air conditioning systems, disaster prevention systems, and security management systems, and actively develop building management systems that can comprehensively (centrally) manage these subsystems. [0003] In operating such a building management system, the BAC network is used as a reliable communication protocol for sharing various information required to control and monitor these subsystems. [0004] Referring to Fig. 1, the building management system of prior art comprises: variou...
