Smart home logic control method and system based on KNX bus protocol

Abstract

The invention discloses a smart home logic control method and system based on the KNX bus protocol. The smart home logic control method comprises the steps that firstly, smart home devices are grouped according to set demands, and the addresses of the grouped smart home devices, the addresses of the smart home device groups and the initial states of the grouped smart home devices are set based on the KNX bus protocol; secondly, control orders are transmitted to a KNX bus through an upper computer in the mode of messages of the addresses of the smart home device groups, a logic controller receives the control orders from the KNX bus, and analysis and judgment based on combinational logical operation and sequential logic operation are conducted on the control orders; finally, the logic controller sends the orders according with the control logic to the KNX bus in the mode of the messages of the addresses of the groups according to the timing sequence, and then intelligent control over a smart home is achieved. By the adoption of the smart home logic control method and system based on the KNX bus protocol, combinational logic verification and sequential logic deduction of the system control orders are achieved, the intelligence level of a smart home system is improved, and the accuracy of intelligent control is guaranteed.

Description

technical field [0001] The invention relates to the field of smart home systems, in particular to a smart home logic control method and system based on the KNX bus protocol. Background technique [0002] In May 1999, the three major European bus protocols EIB, BatiBus and EHSA merged to form the Konnex Association and proposed the KNX (Konnex) bus protocol. Based on EIB, the protocol takes into account the physical layer specifications of BatiBus and EHSA, and absorbs the advantages of configuration modes in BatiBus and EHSA, providing a complete solution for home and building automation. KNX was approved as Chinese standard GB / Z 20965 in 2007. Products with different performances and different manufacturers can realize interoperability, and have passed strict quality control and third-party KNX certification, which further guarantees product quality. The KNX bus protocol provides rich extension forms and standard interfaces for smart home products. [0003] Although smar...
