A general-purpose building automation assembled network communication system and method

Abstract

A general-purpose building automation assembled network communication system and method, belonging to the technical field of intelligent control of the Internet of Things. Technical solution: including: DT0 protocol module, DT1 protocol module, DT2 protocol module, and logical event processor module, the DT0 protocol module is used to abstract the physical layer of the IO port device in the control system from a programming perspective; the DT1 The protocol module is used to realize the interface unification of the communication technology among the various nodes in the control system; the DT2 protocol module is used to realize the information interaction between the various nodes in the control system; the logic event processor module is used to control the The state of the IO port is processed and controlled. The beneficial effects are: the general-purpose building automation assembled network communication system and method described in the present invention have high cost performance, low power consumption, high customization, and modular control, and solve the problem at a relatively low cost. Problems that cannot be customized efficiently and cannot be assembled modularly.

Description

technical field [0001] The invention belongs to the technical field of intelligent control of the Internet of Things, and in particular relates to a general-purpose building automation assembled network communication system and method. Background technique [0002] With the development of wireless Internet of Things technology and the development of PLC technology, people's demand for smart devices is increasing. There are also a large number of various technologies for smart devices. For example, the Chinese patent announcement document with the application number 201410557640.2 discloses an intelligent control method, an intelligent controller and an intelligent control system, which can realize a low-power wireless control method. [0003] There are many existing communication protocol technologies, but there is no unified standardization, which makes their compatibility poor, and there is no standard to standardize and generalize them; although the communication technolo...

AI Technical Summary

Problems solved by technology

[0003] There are many existing communication protocol technologies, but there is no unified standardization, which makes their compatibility poor, and there is no standard to standardize and generalize them; although the communication technologies represented by can bus, 485 and zigbee are relatively expensive Low, but there are problems of incompatibility, poor programmability, and single function of network equipment; although the technology represented by PLC does not have the problem of poor programmability, it has the disadvantages of high cost, high power consumption, low integration and difficult wiring , which also leads to the very high cost of large-scale application of PLC
