Intelligent building management system and method based on pulse current

Abstract

The invention relates to an intelligent building management system and method based on pulse current. A communication center controller controls a meter box monitoring device to transmit meter box pulse voltage carrier signals one by one and controls a distribution box monitoring device to transmit distribution box pulse current carrier signals one by one; the branch-level topology is determined according to the characteristic information of the meter box pulse voltage carrier signal transmitted by each meter box monitoring device and the distribution box pulse current carrier signal transmitted by each distribution box monitoring device; and after the branch-level topology is determined, the communication center controller controls the adapters to transmit corresponding adapter pulse voltage carrier signals one by one, and the meter box-level topology formed by corresponding connection of the adapters and the corresponding meter box monitoring devices is determined according to the adapter pulse voltage carrier signals transmitted by each adapter. According to the invention, the DC power distribution topology of the building is effectively identified and maintained, and the monitoring intelligence and reliability during the use of the electric equipment are improved.

Description

technical field [0001] The invention relates to a building management system and method, in particular to an intelligent building management system and method based on pulse current. Background technique [0002] At present, the function of the building integrated management system is relatively simple. Usually, the power consumption status of the entire building can only be monitored through the power distribution room or the central control room, and the topology relationship of each load on the entire line cannot be analyzed and identified. The electrical equipment of each user and room of the building lacks automatic monitoring means. When the electrical equipment is overloaded or the line is short-circuited or open-circuited during use, it can only rely on manual on-site inspection and maintenance, and cannot take timely monitoring measures. It is difficult to maintain the topology relationship of electrical equipment owned by users, and the problem of chaos before and ...

Problems solved by technology

[0002] At present, the functions of the building integrated management system are relatively single. Usually, the power consumption status of the entire building can only be monitored through the power distribution room or the central control room, and the topological relationship of each load on the entire line cannot be analyzed and identified.

The electrical equipment of each user and room in the building lacks automatic monitoring means. When the electrical equipment is overloaded or the circuit is short-circuited or broken during use, it can only rely on manual on-site inspection and maintenance, and timely monitoring measures cannot be taken. It is difficult to maintain the topological relationship of the user's electrical equipment, and the problem of chaos is prominent

[0003] In the design of high-end new buildings, most of them have deployed intelligent integrated monitoring systems, but due to the influence of various equipment factors, the safety level is low, the fault location is not accurate, and the alarm response is not timely enough, which cannot meet the security needs of today's buildings. Transformer and circuit breaker equipment or branch lines are heavily overloaded and lightly unloaded, and the line load is unbalanced. In severe cases, equipment and lines will be burned, endangering national property and personal safety
