Computing node for distributed computing network

Abstract

The invention discloses a computing node (CPN) for a distributed computing network. The CPN is a computer with information receiving, processing and sending functions. The CPU is equipped with a central processing unit, a memory and a communication interface. A plurality of CPNs form the distributed computing network. Each CPN carries out data interaction with adjacent CPNs in a topology where the CPN is located. Each CPN is equipped with a space attribute. The space attribute indicates an absolute space location where the CPN is located and / or a relative space location in a topology network where the CPN is located. An operating system is built in each computing node. An API interface is provided by each operating system. According to each API interface, various management / control demands and / or strategies are converted into standard computing sequences and the standard computing sequences are converted into instruction sequences capable of being identified by each operating system. The CPNs in the distributed computing network finish computing the sequences together in a distributed and self-organizing mode. The CPNs can be applied to a building automatic control system, and an open, flat and easy-programmable control platform is provided.

Problems solved by technology

[0002] Since the 1980s, people have begun to use information technology to realize intelligent automatic control of buildings, such as broadcasting and audio systems for specific service functions, IC card management systems, hotel room management systems, energy monitoring and management systems, and specific electromechanical equipment. Air conditioning control system, security system, fire protection system, cold station control system, electricity safety system, etc. However, the problem is that the management and control systems in the existing technology are often not so "intelligent", and more than half of the building automatic control systems can only be realized in The central control room remotely monitors the operating parameters of the building environment and system equipment, and manually starts and stops or adjusts the operating status of electromechanical equipment through the central control man-machine interface

[0004] 1. The measurement and control points of the terminal need to be named for global communication, define physical attributes and define the relationship between each other. When the number of measurement and control points is large, the work of on-site configuration and configuration becomes extremely heavy and difficult; This work can only be carried out after the construction of the building is completed and the mechanical and electrical equipment is in place, and the available construction period is very short, so the time is rushed; when the building layout or functional division changes in the later period, it is difficult for the automatic control system to change flexibly;

[0005] 2. It is difficult to realize real sharing of information between subsystems. In order to realize cross-system information sharing, a new system must be established on the upper layer of several existing systems, which requires reconfiguration and definition of the overall situation. The difficulty and The cost is extremely high, and it does not meet the needs of building control intelligence, informatization, and front-end;

[0006] 3. The automatic control platform is closed and has poor versatility. The control software is often designed individually for individual buildings. Therefore, in the process of system transformation and expansion, it is difficult to implement new control strategies flexibly and simply on the existing automatic control platform.

[0007] 4. Cross-system integration is difficult, the existing automatic control system and platform are poor in versatility, and the software and hardware environment is not friendly, requiring developers to have high IT expertise. The control strategy of the communication system, the control strategy of the fire protection system, and the control strategy of the security system) are often formulated by engineers in various fields (HVAC engineers, fire safety engineers, etc.), which makes it difficult for engineers in various fields to Its formulated control strategy and control logic are transformed into the control software of the automatic control system, which makes it difficult for the functions that each subsystem should realize to be integrated in the existing automatic control system and automatic control platform
