Embodiment Construction

[0065] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0066] A home environment comfort control method based on fuzzy intelligent behavior simulation includes a home environment comfort fuzzy control mathematical model and a device for realizing fuzzy control. The comfortable fuzzy control mathematical model of the home environment includes the actual value range of the input and output variables and its fuzzy domain, membership function, fuzzy rules and fuzzy inference. Based on the fuzzy control rule table, the sensor signal is fuzzified , fuzzy reasoning synthesis and defuzzification to realize the fuzzy control of comfortable home environment. Its hardware implementation is as follows: write the fuzzy reasoning response table into the memory unit of the single-chip microcomputer, and in actual application, through the table look-up function of the single-chip microcomputer, take out the value stored in the c...

Abstract

The invention discloses a living environment comfort degree control method based on fuzzy intelligent behavior simulation. The method is characterized by including the following steps: building a living environment comfort degree control device; building a comfort degree fuzzy control mathematic model; implanting a single chip computer fuzzy controller; collecting indoor environment and transmitting the indoor environment to the single chip computer fuzzy controller; carrying out fuzzy reasoning operation through the single chip computer fuzzy controller, and obtaining a fuzzy comfort control output response value; transmitting the value to a drive executor; controlling the work state of a cooler or heater. The method overcomes the difficulties that the indoor comfort degree can not be directly measured and hardware circuits are complex. A comfort degree sensor has the advantages of being scientific and effective in fuzzy judging method, simple in hardware circuit, high in responding speed and the like.

Description

technical field [0001] The invention belongs to a comfort control technology for home environment control, in particular to a home environment comfort control method based on fuzzy intelligent behavior simulation by means of fuzzy control technology. Background technique [0002] Because people's feeling of comfort is fuzzy and subjective, it is difficult to quantify, so from a mathematical point of view, it is a physical quantity that cannot be directly measured. Home dwellers with good experience can often adjust the indoor temperature according to their life experience, so as to make the home environment more comfortable, but after all, there are too few such people, and their subjective dependence is too strong. However, the current patents in this field, such as the indoor thermal environment comfort control system described in the patent [CN202075431U], have the following disadvantages or deficiencies in some specific cases: [0003] (1) There are limitations in model...
