Method and system for building service facility control based on intelligent recognition of semantic instructions

Abstract

The invention discloses a building service facility control method based on intelligent semantic instruction recognition. The building service facility control method based on the intelligent semanticinstruction recognition comprises the following steps: firstly acquiring an instruction speech signal, then converting the instruction speech signal into a primary character string through speech recognition, then determining a low-confidence character from the primary character string, then substituting characteristic parameters of the low-confidence character into a Hopfield neural network to obtain a regular character string, finally generating corresponding control signals according to the regular character string and controlling a building service facility to perform corresponding functions according to the control signals. By the building service facility control method, a user can control operation of various service equipment in the building service facility through an instructionspeech, so that the control mode is more intelligent and convenient; meanwhile, a correct instruction speech can be obtained when pronunciation of the instruction speech issued by the user is not standardized, so that incapability of normally controlling the building service facility by the user due to the problem of the speech is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a control method for building service facilities based on intelligent identification of semantic instructions, and a control system for building service facilities based on intelligent identification of semantic instructions. Background technique [0002] Building service facilities are all kinds of facilities in buildings, including public service facilities and living service facilities, that provide services for the daily operation of the city and people's daily life. The operation of building service facilities is inseparable from the various service equipment in the facilities. Operation, such as elevators in buildings in public places and access control at the entrance of residential buildings, as well as air conditioners and lighting fixtures in bedrooms in private clubs, these service equipments work together to ensure the normal operation of building service f...

Problems solved by technology

[0005] However, in the current methods of controlling the operation of devices by voice and realizing various functions, relatively simple speech recognizers are used, which cannot be used for different accents, irregular pronunciation and unclear enunciation of speaking users. Response and processing, so that the command voice may not be correctly recognized, resulting in the failure to control the operation of the facility
