    • 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.
    • 根据一个实施例,调度装置向建筑物中的通信模块发送查询,并且从通信模块接收在监视控制点处测量的设施信息。 对于每个通信模块,存储网络地址,发送查询之后接收设施信息的等待时间以及与监视控制点的连接。 当接收到指示至少一个监视控制点的服务请求时,生成包括由服务请求指示的监视控制点连接的通信模块的网络地址的查询。 基于对应于通信模块的等待时间来确定每个查询的优先级。 基于优先级将每个查询添加到第一个发送队列或第二个发送队列。 当发送查询时,从第一发送队列发送的定时与从第二发送队列发送的定时相同或较早。
