Say.

A neural network consists of an input layer consisting of multiple neurons, an intermediate layer (hidden layer) consisting of multiple neurons, and an output layer consisting of multiple neurons. The intermediate layer may be one layer, or two or more layers.

For example, in a three-layer neural network, when multiple inputs are input to the input layers (X1-X3), the values are multiplied by weight W1 (w11-w16) and input to the intermediate layers (Y1-Y2). The result is further multiplied by weight W2 (w21 to w26) and output from the output layer (Z1 to Z3). This output result varies depending on the values of weights W1 and W2.

According to the learning data acquired by the data acquisition unit 102, the neural network performs supervised learning, based on the image data of the indoor unit 1 received from the portable terminal 13 of the air conditioning system 500. Generate a trained model that infers no.

In step c2, the inference unit 203 inputs the image data of the indoor unit 1 acquired in step c1 to the learned model stored in the learned model storage device 301. In step c3, the inference unit 203 uses the learned model to infer whether maintenance of the indoor unit 1 is necessary from the image data of the indoor unit 1 acquired in step c1.

As an example, in step c3, as an inference as to whether or not maintenance is necessary, whether the filter 9 needs to be cleaned, whether the filter 9 needs to be replaced, whether the drain pan 22 needs to be cleaned, whether the panel (decorative panel 2, filter panel 7, Infer the parts that need maintenance and maintenance work items, such as whether the inside of the side panel 5) needs to be cleaned or whether the panel (decorative panel 2, filter panel 7, side panel 5) needs to be replaced. estimated by Then, depending on the dirty state of the location estimated as the location requiring maintenance, the timing of maintenance is estimated by inference, such as whether maintenance is required immediately or when maintenance will be required in the future.

At step c4, the maintenance planning device 600 immediately determines whether or not maintenance is necessary based on the inference result of the inference unit 203 as to whether maintenance is necessary at step c3.

When it is determined in step c4 that immediate maintenance is required, in step c5, the maintenance planning device 600 sends maintenance to the location of the air conditioning system 500 including the indoor unit 1 determined to require maintenance. It decides to dispatch a worker to do so, and proceeds to step c7. When it is decided to dispatch a worker for maintenance, the maintenance work item estimated in step c3 is further determined as the work item for the worker to be dispatched.

When it is determined in step c4 that immediate maintenance is not required, in step c6, the maintenance planning device 600 determines the timing of future maintenance, and proceeds to step c7. For example, in step c6, the estimated timing of maintenance, such as when maintenance will be required in the future estimated in step c3, is determined as the future maintenance timing.

In step c7, the maintenance planning device 600 plans a maintenance schedule based on the decisions made in step c5 or steps c6. In step c7, for example, when it is decided to dispatch workers for maintenance in step c5, based on the determined maintenance work items, how many workers to dispatch and how much Develop a maintenance schedule, such as scheduling work hours.
