According to one embodiment, a scheduling apparatus sends queries to communication modules in buildings and receives facility information measured at monitor-control points from the communication modules. As for each communication module, a network address, a waiting time to receive the facility information after sending a query, and a connection with the monitor-control points, are stored. When a service request indicating at least one monitor-control point is received, queries each including the network address of a communication module connected with a monitor-control point indicated by the service request, are generated. A priority of each query is decided based on the waiting time corresponding to the communication module. Each query is added to a first send queue or a second send queue based on the priority. When queries are sent, a timing to send from the first send queue is same as or earlier than a timing to send from the second send queue.

To provide an entry control system as well as an entry control method allowing for an easy entry of user, permitting a restriction to persons who have a legitimate right to enter a facility, an illuminating device (1) emits a modulated visible light signal 13 modulated by use of a door ID code into a preset illumination range, the modulated visible light signal 13 from the illuminating device (1) is received by a mobile terminal (2) portable by the user, where it is demodulated for wireless signal transmission, and the door ID code transmitted from the mobile terminal (2) is received by an authentication device (3), which judges whether or not the door ID code is legitimate, and generates an unlock command when the door ID code is judged to be legitimate, and a door (4) for a facility controlled of entry receives the unlock command from the authentication device (3), whereby it is unlocked.
摘要:
A humidity estimation device connected with an air-conditioner includes a charge airflow rate estimation (CARE) unit, a charge air absolute humidity estimation (CAAHE) unit, an indoor generated vapor amount estimation (IGVAE) unit, and an indoor absolute humidity estimation (IAHE) unit. The CARE unit calculates an estimated charge airflow rate (ECAR) of the air-conditioner based on operation control information of the charge fan and a preset fan differential pressure. The CAAHE unit calculates an estimated charge air absolute humidity (ECAAH) of the air-conditioner based on a charge air temperature and a preset charge air relative humidity. The IGVAE unit calculates an estimated indoor generated vapor amount (EIGVA) based on an indoor temperature, the number of persons in the room and activity index values of the persons. The IAHE unit calculates an estimated absolute humidity in the room based on the ECAR, the ECAAH and the EIGVA.
