Embodiment Construction

[0025] exist figure 1 The multi-building fault detection system of this embodiment is shown as an example in FIG. The multi-building fault detection system includes a plurality of buildings (buildings) 10A, 10B, 10C . . . and a management building 14 . Each building 10A, 10B, 10C... is provided with a failure detection device 16 (gateway), and the failure detection device 16 transmits failure information to a management server 18 that manages the building 14 via a network line 12 such as the Internet.

[0026] Conventionally, in the operation of a building / energy management system (BEMS), administrators are resident in each building 10A, 10B, 10C, . In contrast, by constructing figure 1 The multi-building fault detection system shown can realize labor-saving of buildings 10A, 10B, 10C....

[0027] For example, at night when the number of failure alarms and abnormal alarms is relatively reduced, the administrator is left in only the management building 14, and the administra...

Abstract

A fault detection device (16) is connected to a network (21), and service information, which is information on an object modeled as a device to be controlled and characteristics of the object, circulates through the network (21). A fault detection device (16) has a service information receiving unit (38), an alarm message extracting unit (42), and a name confirming unit (44). A service information receiving unit (38) receives service information. An alarm message extraction unit (42) extracts service information including an alarm notification from the received service information. A name confirming unit (44) uses the sender object identifier added to the service information including the alarm notification as a destination, and requests the name of the object and at least one of normal values ​​and abnormal values ​​that current value characteristics can take. Thus, a light-load failure detection system can be constructed.

Description

technical field [0001] The present invention relates to a failure detection device capable of detecting failures of building equipment. Background technique [0002] Conventionally, there is known a building / energy management system (BEMS: Building and Energy Management System) that manages building equipment and electric power. In the BEMS, communication is performed between various control devices (network devices) based on, for example, the BACnet (Building Automation and Control networking) protocol established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). [0003] Typically, a decentralized control system is employed when applying a BEMS to a prescribed building. That is, lower-level control devices (B-BC: BACnet Building Controller) are provided for each equipment group type such as air-conditioning equipment, lighting equipment, and disaster prevention equipment. Furthermore, each lower control device is managed and opera...
