Abstract:
A management apparatus for an air-conditioning apparatus configured to manage a plurality of air-conditioning apparatuses configured to condition air in an air-conditioning target space includes: a management-side communication unit to receive data of arrival locations and arrival times in the space transmitted from a plurality of terminal devices; and a management-side arithmetic unit configured to perform totaling based on the data of the arrival locations and the arrival times received by the management-side communication unit, and to perform a process of determining an order in which operation is started in the plurality of air-conditioning apparatuses. Operation is performed in order, and thus a steep increase in power consumption can be reduced.
Abstract:
Provided is a management apparatus, which is to be connected to a device, and is configured to manage the device. The management apparatus includes: a display unit configured to display a state of the device; and a wireless communication unit configured to wirelessly communicate to and from a mobile terminal. When a distance between the mobile terminal and the management apparatus has become smaller than a threshold value, the management apparatus displays on the display unit management program information on a management program for managing the device.
Abstract:
A sensor device includes: a primary battery; a secondary battery that is charged by energy harvesting; a sensor that is operated by electricity supplied from the primary battery or from the secondary battery; a source-of-electricity switching circuit that switches a source of electricity for the sensor between the primary battery and the secondary battery; a notification unit that makes a notification indicating information; and a controller that controls the sensor and the notification unit. The source-of-electricity switching circuit switches the source of electricity to the primary battery when a voltage of the secondary battery falls below a predetermined first reference voltage in the case where the source of electricity is the secondary battery. The controller causes the notification unit to make a notification indicating that an operation of the secondary battery is unstable, when the voltage of the secondary battery falls below the first reference voltage.
Abstract:
An air-conditioning control system includes a plurality of air-conditioning apparatuses each provided with an indoor unit and an outdoor unit; a master remote control device associated with one or more of the plurality of air-conditioning apparatuses and adapted to control operation of the associated air-conditioning apparatus or apparatuses; and one or more slave remote control devices connected with the master remote control device using a first communication system, associated with a remaining one or ones of the plurality of air-conditioning apparatuses, and adapted to control operation of the associated air-conditioning apparatus or apparatuses, in which the indoor units of the air-conditioning apparatuses are connected with an associated one or ones of the master remote control device and the slave remote control device or devices using a second communication system different from the first communication system, and the master remote control device controls the operation of the remaining air-conditioning apparatus or apparatuses via the slave remote control device or devices.
Abstract:
An air-conditioning remote controller for operating an air-conditioning apparatus is provided. The air-conditioning remote controller includes a display unit, an image acquisition processing unit, and a display processing unit. The display unit displays various information. The image acquisition processing unit acquires image data from an external communication terminal. The display processing unit displays, on the display unit, a settings management screen used for operating the air-conditioning apparatus, and the image data acquired by the image acquisition processing unit from the communication terminal.
