Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] Such as figure 1 As shown, a control system based on the FSM short-distance home communication protocol includes a host and several slaves connected to the host. The master is connected to several slaves via the same data bus 1 .

[0020] The host includes a sending buffer module 17, an insertion module 16, and a sending register module 14 connected in sequence. This main frame also comprises FIFO parallel / serial conversion module 11, cyclic redundancy check code generator module 13; The signal output terminals of the module 14 are connected. In the figure, the FIFO parallel / serial conversion module 11 sends data through a TXD data packet 10 , and the cyclic redundancy check code generator module 13 sends data through a TXC data packet 12 . The inserting modul...

Abstract

The invention discloses a control system and a control method for a short-distance home communication protocol based on an FSM (Finite State Machine). In a short-distance home communication system, nodes of a host machine and various slave machines are connected in parallel onto a same data bus, in order to avoid conflict of the data bus, the communication is agreed to be initiated by the host machine, and all of the slave machines are in a receiving state at any time; and moreover, the slave machines make responses only after the slave machines receive the address codes matched with the addresses of the slave machines; and meanwhile, the slave machines cannot be communicated mutually. The communication protocol can realize unification of communication standards between control modules of household electrical appliances, so that the automation control of the household electrical appliances can be realized safely.

Description

technical field [0001] The invention relates to the technical field of finite state machines, in particular to a control system and a control method of an FSM-based short-distance home communication protocol. Background technique [0002] With the rapid improvement of people's living standards, the number of household appliances nodes is increasing rapidly, and people's requirements for the intelligent control of household appliances are also getting higher and higher. However, since there is no unified standard for the communication between the control modules of the home appliances, the communication protocols between the control modules of the home appliances are diversified, and the communication interface programs are complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control system and control method based on the short-distance household communication protocol based on FSM. The basic idea, so a...
