Abstract: A water supply apparatus is provided to meet demands for energy saving by controlling the rotational speed of a pump (1), for example, so as to lower the rotational speed in the time zone when water is not used much while avoiding the time zone when water is used in large quantities. The water supply apparatus includes the pump (1) configured to pressurize and deliver water, a frequency converter configured to supply electric power to the pump (1) to operate the pump (1) at a variable speed, and a controller (15) configured to send operating signals to the frequency converter so as to operate the pump (1) either at a first operation or at a second operation with less power consumption than the first operation. The controller (15) is configured to judge whether the operation of the pump (1) should be shifted from the first operation to the second operation based on an operational state of the pump (1).

Abstract: The present invention provides a water supply apparatus capable of performing a backup operation, without lowering water supply capability, when a failure has occurred in one control substrate due to surge or noise caused by lightning or due to lifetimes of various sensors, by switching to the other control substrate, and capable of reliably performing the backup operation by means of devices that prevent failure of the control substrates. The water supply apparatus (1) includes: a plurality of pumps (3); a plurality of inverters (INV) each configured to change and control a rotational frequency of a corresponding one of the plurality of pumps (3); and a plurality of control substrates (CN) configured to control the plurality of inverters (INV). When an abnormality occurs in one control substrate, other control substrate backs up the one control substrate to thereby allow the water supply apparatus to continue its operations. The one control substrate, the plurality of inverters (INV), and the other control substrate are connected in series by communication lines. A switch (SW1) for turning on and off a communication is provided on the communication lines.

Abstract: An information processing system includes a terminal apparatus that sends the received machine-type identification information and state history information received from the monitoring target apparatus by near field communication, an information processing apparatus that receives the machine-type identification information and the state history information from the terminal apparatus, and a storage apparatus that accumulates machine-type identification information identifying a machine type of a monitoring target apparatus and normal-state history information in an associated manner. When the information processing apparatus receives the machine-type identification information and state history information about a certain monitoring target apparatus from the terminal apparatus, the information processing apparatus compares the normal-state history information accumulated in the storage apparatus in association with the machine-type identification information and the received state history information, judges whether an operation state of the monitoring target apparatus is normal, and sends a judgment result to the terminal apparatus.
