Decentralized distributed control system and deployment method thereof

Abstract

The invention provides a decentralized distributed control system and a deployment method. The system comprises a cloud platform, a wireless network base station in communication connection with the cloud platform, a first protocol conversion unit which is disposed at the edge of a network coverage range of the wireless network base station and is in communication connection with the wireless network base station, a first wireless direct digital control unit arranged outside the network coverage area of the wireless network base station and in communication connection with the first protocol conversion unit, and a second wireless direct digital control unit arranged inside the network coverage area of the wireless network base station and in communication connection with the wireless network base station. The system has the advantages that the problems that a wired monitoring system is high in cost, difficult to expand in the later period and difficult to maintain under the condition that the main node breaks down are solved, and the technical effects that the monitoring system is constructed at low cost, later-period expansion is facilitated, and rapid maintenance is conducted under the condition that the main node breaks down are achieved.

Description

technical field [0001] The present application relates to the technical field of building automation control, in particular to a decentralized distributed control system and a deployment method thereof. Background technique [0002] Building equipment monitoring is an important part of building automation deployments. Building equipment monitoring mainly monitors the following equipment: refrigeration unit, air conditioning unit, fresh air unit, supply and exhaust fan unit, heat pump unit, boiler, fan coil unit, elevator, lighting, hot water, sewage, energy management. In addition, the areas monitored by building equipment mainly include centralized underground computer rooms, centralized above-ground computer rooms, public areas on each floor, and owner areas. [0003] In related technologies, solutions for building equipment monitoring are all wired solutions, including RS485-based Modbus communication, Ethernet-based BACnet, and the like. [0004] For centralized underg...
