Air-conditioning control device and air-conditioning control system

An air conditioner includes a camera to capture an image of a drain pan inside the air conditioner. An air-conditioning management device acquires, from the air conditioner, captured image information indicating an image of the drain pan captured by the air conditioner. The air-conditioning management device compares the captured image information with reference image information indicating a captured image of the drain pan used as a reference to calculate a dirtiness degree. The air-conditioning management device transmits, to a monitoring terminal, information useful for monitoring of the drain pan, such as the capture image information, information indicating the dirtiness degree, and the like.

A mobile terminal capable of obtaining information provided from a server includes: a communication unit capable of communicating with, via a first communication path, an associated terminal in one of a plurality of areas, the associated terminal being placed in the one of the plurality of areas, being a terminal associated with the mobile terminal, and being one of a plurality of area terminals placed in corresponding ones of the plurality of areas; and a display unit capable of displaying service information provided from the server, the service information including first information and second information different from the first information. The display unit displays the first information when the communication unit is able to communicate with the associated terminal, or displays the second information when the communication unit is unable to communicate with the associated terminal.

Mobile terminal and information providing system

A wireless terminal performs communication setting processing in response to connection processing from an air conditioning management apparatus. The air conditioning management apparatus sends, to a wireless terminal, a wireless communication electronic message in which an air conditioning communication electronic message is packaged. Upon receipt of the wireless communication electronic message, the wireless terminal converts the content of the communication. Upon receipt of the air conditioning communication electronic message, an air conditioner executes a request command described in the air conditioning communication electronic message. Upon receipt of the air conditioning communication electronic message, the wireless terminal converts the content of the communication. Upon receipt of the wireless communication electronic message, the air conditioning management apparatus performs response reception processing.

A schedule data acquisition requestor requests and acquires schedule data from a sub controller. When a modification to the acquired schedule data is made, a schedule data update requestor sends the modified schedule data to the sub controller and requests an update. A schedule data update processor sends a permission notification to a main controller in response to the update request and writes the modified schedule data onto its own flash memory. Conversely, when a rejection notification is sent from the sub controller, the schedule data update requestor displays a warning message and new schedule data on a screen.

Equipment system and control apparatus

A control system transmits, to a remote monitoring server, report data generated based on operation data. The control system includes a facility-device management apparatus that generates report data based on the operation data, and a relay device that communicates with the remote monitoring server via an intra-facility LAN and communicates with the facility-device management apparatus via a connection line. The facility-device management apparatus includes setting means for setting whether or not the report data is to be transmitted to the remote monitoring server, first transmission means for transmitting the report data to the remote monitoring server, and second transmission means for transmitting the report data to the relay device. The relay device includes forwarding means for transmitting, to the intra-facility LAN, the report data received from the facility-device management apparatus.

Control system and management apparatus

A monitoring system comprises an equipment management device, a relay server, and monitoring terminals. The equipment management device is configured to establish with the relay server first communication for notifying the monitoring terminals of the states of equipment items. Furthermore, the equipment management device is configured to establish with the relay server second communication, which is different from the first communication, for monitoring equipment information regarding the equipment items from each of the monitoring terminals. The monitoring terminals establish the first communication and second communication with the relay server. The relay server is configured to relay the first communication and second communication.

Monitoring system, facility management device, monitoring method, and program

An equipment manager manages connected equipment. A Web server is able to provide Web contents that include a monitoring program for monitoring the states of equipment managed by plural equipment management devices. A Web-contents-display controller acquires the Web contents that are transmitted from the Web server, executes the monitoring program, acquires an equipment-management-device-address list, uses the acquired equipment-management-device-address list to connect to each of the plural equipment management devices, acquires equipment data that is managed by each of the equipment management devices, and displays that equipment data on one screen of the Web browser.

Equipment management system and program

A standard schedule creator creates a standard schedule that makes it possible to achieve a target presented by target data. A seasonal schedule updater, monthly schedule updater, weekly schedule updater, and current day schedule updater update the created standard schedule using the corresponding weather forecast data to create an operation schedule of an air conditioner in which the weather forecast is properly reflected.

Air-conditioning management device, air-conditioning management method, and program

A facility management device manages communication data that is transmitted and received between remote controllers and an outdoor unit and/or indoor units. A temporary-memory controller stores communication data that was received by a communicator, and transmission-waveform data that was acquired by a transmission-waveform data acquirer for a specified amount of time in a temporary memory. An abnormality determiner determines whether or not there is abnormality in the communication data that is stored in the temporary memory. When it is determined that there is abnormality in the communication data stored in the temporary memory, a data copier stores all of the data that is stored in the temporary memory in an abnormal-data memory.

An equipment manager manages the operating state of equipment. A user verification processor performs user verification according to a request from a monitoring terminal, and when user verification is successful, generates for each facility management device a verification code in which verification data, to which a digital signature has been added using a self-owned secret key, has been encoded using a public key of each facility management device, and transmits the verification codes to the monitoring terminal. After receiving the verification code, a verification code analyzer decodes the verification code using the self-owned secret key, and performs verification by verifying the digital signature using the public key of a representative facility management device. When verification is successful, a Web server is able to monitor and manipulate data that indicates the operating states of all of the equipment that is managed by the equipment manager.
