first embodiment

[0032]FIG. 1 is a functional block diagram schematically illustrating an air conditioning control system 1 according to a

[0033]Each of functional blocks illustrated in FIG. 1 is implemented such that a processor such as a CPU and a GPU included in a computer such as a numerical controller, a cell computer, a host computer, and a cloud server controls an operation of each unit of a device in accordance with each system program.

[0034]An air conditioning control system 1 according to the present embodiment includes an environment management unit 100, an inference processing unit 200, and a learning model storage unit 300. The environment management unit 100 manages an environment (a room in which an air conditioner 130 is installed, for example) at least a state of which is an object of observation and inference. The inference processing unit 200 infers a state of the environment. The learning model storage unit 300 stores and manages a plurality of learning models. This air conditioni...

second embodiment

[0054]FIG. 3 is a functional block diagram schematically illustrating an air conditioning control system 1 according to a

[0055]In the air conditioning control system 1 according to the present embodiment, each functional block is mounted on one air conditioning controller 2 (which is to be structured on a central management device of air conditioners, a numerical controller, or the like). In such configuration, the air conditioning control system 1 according to the present embodiment infers a method for controlling the air conditioners 130 in an environment managed by the air conditioning control system 1 by using a learning model differing depending on installation states and operation states of the machines 120 in the environment managed by the air conditioning control system 1 so as to control the air conditioners 130 in the environment managed by the air conditioning control system 1. Further, one air conditioning controller 2 is capable of generating / updating learning models ea...

third embodiment

[0056]FIG. 4 is a functional block diagram schematically illustrating an air conditioning control system 1 according to a

[0057]In the air conditioning control system 1 according to the present embodiment, the environment management unit 100, the inference processing unit 200, and the air conditioning control unit 400 are mounted on the air conditioning controller 2, and the learning model storage unit 300 and the learning model generation unit 500 are mounted on a machine learning device 3 which is connected with the air conditioning controller 2 via standard interface and network. The machine learning device 3 may be mounted on a cell computer, a host computer, a cloud server, or a database server. In such configuration, inference processing using a learned model, which is relatively light processing, can be executed on the air conditioning controller 2 and processing for generating / updating a learning model, which is relatively heavy processing, can be executed on the machine lear...

Abstract

An air conditioning control system for controlling an air conditioner specifies a condition in an environment, detects a state amount representing the environment, infers a control method for the air conditioner in the environment based on the state amount that is detected, and controls the air conditioner based on the control method that is inferred. Further, the air conditioning control system generates or updates a plurality of learning models through machine learning using the state amount that is detected and stores the plurality of learning models in a manner such that they are associated with combinations of conditions in the environment.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to an air conditioning control system and especially relates to an air conditioning control system that controls air conditioning while switching learning models in accordance with an installation state and an operation state of machines in a factory.2. Description of the Related Art[0002]Since a plurality of machines (machine tools, for example) ate installed in a factory and the temperature in the factory affects machining accuracy in precision machining, an air conditioner for controlling environment conditions inside the factory is provided. Production in a factory is instructed based on a production plan. In order to produce products instructed in the production plan by an instructed delivery date, operation states and machining conditions of a plurality of machines arc controlled find an operation state of an air conditioner is controlled to realize temperature conditions (temperature and u...
