Abstract: A monitoring system includes a battery-type power supply device. The battery-type power supply device is mounted in a battery box of an operation device for remotely operating an external device. A server apparatus is connected via a network to the battery-type power supply device. The battery-type power supply device includes current detection means for detecting an internal current flowing in the operation device, and transmission means for transmitting data indicating a fluctuation in the detected internal current to outside. The server apparatus includes means for receiving the data indicating a fluctuation, operation identification means for identifying an operation portion that has been operated in the external device based on the data indicating the fluctuation, and means for transmitting information relating to the identified operation portion or a result of aggregation of the information to external processing devices via the network.

Abstract: A battery-type power supply device realizes data transmission while also supplying power to a battery-driven external load device in a state in which the battery-type power supply device is mounted in a battery box of the external load device. The battery-type power supply device is mountable in the battery box of the external load device, has a shape and dimensions conforming to battery standards, and is capable of housing a small-size battery therein. An output transistor is interposed between a housed battery and an outer electrode terminal, and opening and closing of the output transistor are controlled by a PWM control section at a duty ratio corresponding to an instruction received from an external information processing device by a radio communication section, so that the battery type power supply device thereby functions as a switching power supply.

Abstract: An objective of the present invention is to realize a voltage detection function in a cell type power supply device having a wireless communication function. A cell type power supply device 1 is attached to a cell box 12 of an external load device 11 alone or in series with another external cell 13. A housing 18 has a shape and dimensions based on a cell standard, and front and rear terminals of the external cell held in a cell holder 2 in the housing 18 are to be in contact with an inner positive terminal 5 and an inner negative terminal 6. An outer positive terminal 3 connected to the inner positive terminal is provided on a front end surface of the housing, and an outer negative terminal 4 connected to the inner negative terminal is provided on a rear end surface of the housing. An output transistor 32 is interposed at least one of between the inner negative terminal and the outer negative terminal and between the inner positive terminal and the outer positive terminal.
