The inverter-integrated motor 8 includes an electric motor 4 for driving the pump 3, an inverter 5 for controlling the rotation frequency of the electric motor 4 to drive the electric motor 4, and a fan 6 for cooling the inverter 5. The pump device 2 further includes a control panel 7 which is an example of a control unit that controls the inverter 5. There is also a form in which an inverter is built in the motor.

A discharge pipe 20 is connected to the discharge side of the pump 3, and tap water in a water receiving tank (not shown) is supplied by the pump 3 to a terminal demand destination such as a house. The discharge pipe 20 is provided with a flow switch 24 as one of the check valve 22 and the sensor 23, and the output signal of the flow switch 24 is input to the control panel 7. The check valve 22 is a check valve for preventing water from flowing back from the discharge side to the suction side when the pump 3 is stopped, and the flow switch 24 has a reduced amount of water in the discharge pipe 20.

Since a network is generated by edge computers 1-1 to 1-3 and various sensors, it is possible to check and collect information on pumps within the network range even in an environment where communication with the cloud or server is not possible.

The edge computers 1-1 to 1-3 may be installed not only in the control panel of the pump device or the water supply device but also in the switchboard to which the pump is connected as long as the communication can reach.

The edge computers 1-1 to 1-3 are installed within a range in which they can be wirelessly connected to various sensors, control panels, and water supply devices, but if that is not possible, PLC may be used for communication.

For example, the data in the first row of the state value data tables T2-1 and T2-3 has the output current value of the inverter even though there is no flow rate, so that the pump or motor is stuck or stuck. Since it can be determined that the rotation is defective, for example, the processor 14 sets the diagnosis result as "abnormal", sets the abnormality content as "rotating body sticking / defect", and outputs the diagnosis result and the abnormality content. Then, the processor 14 stores the diagnosis result and the abnormality content in the record of the first row of the state value data tables T2-1 and T2-3. Here, the storage 11 stores the diagnostic criteria in advance, and the processor 14 compares, for example, one or more sensor data (for example, a set of the output signal of the flow switch 24 and the output current value of the inverter) with the diagnostic criteria. Then, it may be determined whether or not it is abnormal, and if it is abnormal, the content of the abnormality may be determined, and the diagnosis result and / or the content of the abnormality may be output. Here, the diagnostic criterion is, for example, when the output current value of the inverter exists even though the output signal data of the flow switch 24 is at a high level (no flow rate), the diagnostic result is "abnormal" and the abnormality content is "rotating body". It is said to be "sticking / defective".
