    • A plurality of wireless communication methods are combined, networks to be used are dynamically selected by evaluating each network quality, and a packet format is changed adaptively to realize necessary reliability. The wireless communication apparatus has a network interface, a data interface, a quality interface, an allocation control part, a quality database, a quality update part, communication units and antennas. The wireless communication apparatus receives data and a requested quality from an application apparatus, selects the communication unit and communication method suitable for the requested quality, and transmits the data and requested quality. The communication unit receives a communication quality of the communication partner, and the quality update part updates the communication quality state in the quality database.
    • 多个无线通信方法组合,通过评估每个网络质量动态地选择要使用的网络,并且分组格式自适应地改变以实现必要的可靠性。 无线通信装置具有网络接口,数据接口,质量接口,分配控制部,质量数据库,质量更新部,通信单元和天线。 无线通信装置从应用装置接收数据和请求的质量,选择适合所请求质量的通信单元和通信方法,并发送数据和请求的质量。 通信单元接收通信伙伴的通信质量,质量更新部更新质量数据库中的通信质量状态。

    • In the construction of a wireless network in a building, structure conditions such as the floor plan of the building and the shape of the floor, material conditions such as materials for structures, and the like have a great effect on radio wave propagation characteristics. This causes a problem that unless these pieces of information are taken into consideration, an accurate layout design of wireless base stations cannot be made. In the construction of a new wireless network in a building, a wireless network similar to structure conditions of a newly constructed building is extracted from structure conditions of past buildings in which a wireless network is constructed. The layout positions of wireless base stations used in the extracted wireless network are regarded as the layout positions of wireless base stations in the new wireless network.
    • 在建筑物中的无线网络的构造中,诸如建筑物的平面图和地板的形状等结构条件,诸如结构材料的材料条件等对无线电波传播特性具有很大的影响。 这导致了一个问题,除非考虑到这些信息,否则无法进行无线基站的精确布局设计。 在建筑物中建立新的无线网络时,从构建无线网络的过去建筑物的结构条件中提取类似于新建建筑物的结构条件的无线网络。 提取的无线网络中使用的无线基站的布​​局位置被认为是新无线网络中无线基站的布​​局位置。

    • A feedback control device capable of continuously performing high-accuracy, stable control even in cases where any of multiple controllers for controlling a controlled system becomes incapable of control action. A controller (master controller) generates control data for stably controlling a heater by feedback control, controls the heater in accordance with the control data, and sends the control data to the other controller (slave controller). The slave controller receives the control data from the master controller but does not control the heater while the master controller is operating normally. If the master controller develops anomaly and becomes incapable of normal control action, the slave controller initiates feedback control of the heater in accordance with the control data received from the master controller immediately before the anomaly occurred, and controls the heater thereafter in accordance with control data generated thereby.
    • 即使在用于控制受控系统的多个控制器中的任一个变得无法控制的情况下,也能够连续执行高精度,稳定的控制的反馈控制装置。 控制器(主控制器)通过反馈控制产生用于稳定地控制加热器的控制数据,根据控制数据控制加热器,并将控制数据发送到另一控制器(从控制器)。 从控制器从主控制器接收控制数据,但在主控制器正常运行时不控制加热器。 如果主控制器出现异常并且不能正常控制动作,则从控制器根据在异常发生之前从主控制器接收的控制数据启动加热器的反馈控制,并根据控制数据控制加热器 由此产生。
