The storage unit prestores element image data presenting an element image contained in a display image in an image data region that is a continuous storage region, and prestores draw command data containing data for creating display data presenting the display image in which the element image is placed in a draw command region that is a continuous storage region. The central processing unit makes reference to a screen management table when a predetermined drawing condition is satisfied to identify and output the draw command identification data corresponding to the satisfied drawing condition. The draw processing unit acquires from the storage unit the draw command data identified with the output draw command identification data, and creates and outputs to the display unit the display data placing the element image based on the acquired draw command data.

Control device and remote controller

A device control determiner outputs a control information request containing a condition of facility devices in a data possessing device group possessing control information, and a kind of the control information. A connection relationship manager manages information regarding a connection relationship among each of the plurality of facility devices. A connection route database stores information regarding a connection route from a reference device that is a reference among the plurality of facility devices to another facility device. The device grouper creates a data possessing device group based on the control information request, the connection route database and information managed by the connection relationship manager. An information collective obtainer obtains control information from the facility device in the data possessing device group through a communicator, and creates a data array of the obtained control information.

A facility equipment operation device includes an affected section determiner and a mismatch detector. An affected section determiner computes an affected section that is affected by a controlled equipment that is facility equipment with a changed control parameter, by referencing data including an installation position of facility equipment in an objective space, and a capability related to an area affected by the facility equipment. The mismatch detector detects a mismatched state on the basis of whether or not an effect exerted by the controlled equipment on the affected section when the controlled equipment operates according to the changed control parameter, and an effect exerted on the affected section by a facility equipment currently operating, are in a predetermined relationship.

A first electronic message collector collects electronic messages travelling on a first network and stores the electronic messages in a first storage. A second electronic message collector collects electronic messages travelling on a second network and stores the electronic messages in a second storage. An electronic message associator retains a mapping table in which the correlation, or similar, between electronic messages travelling from the first network to a gateway device and electronic messages travelling from the gateway device the second network are defined. The electronic message associator references the mapping table and associates the electronic messages stored in the second storage with the electronic messages stored in the first storage. From the result of the above-mentioned association, a status analyzer determines whether or not receipt of electronic message between the first network and the second network is accomplished normally.

By efficiently holding only information necessary for a desired control from among information that can be obtained from equipment such as air conditioners, lighting devices and other devices, the control of the air conditioners and other devices according to the situation is obtained with small-capacity memory resources. This facilitates uploading to an air conditioner control device having a relatively small memory capacity and makes it possible to efficiently customize the installed control program.

Upon receiving an update registration request for operating state data from a user I/F controller (a device controller), an arbitrator determines whether to permit the update registration request. Upon permission, the arbitrator retains the update registration request for operating state data. If the update registration request is sent by the user I/F controller (the device controller) and the request is permitted by the arbitrator, the user I/F controller (the device controller) generates FIFO registration data, stores the data in a first FIFO buffer (a second FIFO buffer), and saves the data in a display data storage (a device control data storage). If the arbitrator is retaining an update registration request by the other controller, the user I/F controller (the device controller) retrieves the FIFO registration data from the second FIFO buffer (the first FIFO buffer) and saves the data in the display data storage (the device control data storage).
