An increase in communication traffic at the time of transmission of commands of controlling power consumption of individual buildings can be suppressed so as to be low. A wide area management system includes a wide area management device that includes a database that stores a command table and a transmission unit that transmits a control command to each uppermost-level building management device and building management devices, each of which includes a database that stores a management table and a building-associated correspondence table, a transfer unit where, in a case where a reception unit receives the control command, specifies lower-level building management devices by referring to the management table and transfers the received control command to each of the specified building management devices, an event program extraction unit that extracts an event program corresponding to the control command from a building-associated correspondence table, and an event program execution unit that executes the extracted event program to control power consumption of the buildings.

Managing energy consumption of a building in an interconnected wide area management system

Even when there are a lot of buildings as a management target, a power consumption of each building can be appropriately managed. A broad area management systemis provided with a broad area management apparatusin which a control command reception unitreceiving a selection of a control command of a power consumption from an operation terminal of an administrator and a transmission unittransmitting received one control command to a plurality of building management apparatusesare included, and the building management apparatusin which an event program execution unitstoring an event program in association with the control command, a reception unitextracting the event program corresponding to the control command from the event program execution unitin a case where the control command is received from the broad area management apparatus, an event program extraction unitcontrolling the power consumption of each facilityby executing the extracted event program.

Broad area management system, broad area management apparatus, building management apparatus, and broad area management method

A security system with processing optimized for monitoring the actions of a surveillance subject and detecting abnormal actions. The action record of an individual is monitored using a sensor network security system SNS, and the development of an action event is reported as an action, and the corresponding processing of the security system SCS is determined based on this action.

Security system

In an information processor having a central processing unit, a main storage which is accessed by the central processing unit, and an input/output processing unit which controls transfer of information between the central processing unit as well as the main storage and exterior of the information processor; a memory area of the main storage is partitioned into a software area and a hardware area, a train of instructions for inspecting the central processing unit, the main storage and the input/output processing unit are stored in the hardware area, and the central processing unit executes a program stored in the software area and the instruction train stored in the hardware area, alternately at desired intervals so as to decide existence or nonexistence of occurrence of an error on the basis of an executed result of the instruction train.
