    • Disclosed is a wireless communications device with strong realtime performance, giving rise to no latency in communications even if communications errors arise in the communication frame MAC header. MAC header information is used to determine whether or not the destination address of a received data frame is the address of a concerned wireless communications device (1). MAC header information allocated among a plurality of MAC headers is employed in selecting MAC header information without errors. If all MAC header information is in error, a majority determination processing unit (13) is used to effect a majority determination of the MAC header information and generate correct MAC header information. A received data extraction unit (14) removes the received frame header, etc., extracts the received data, and outputs same to an external device.

    • A plurality of slave stations receive a plurality of apparatus information signals concerning apparatus to be controlled (or sensors), and a master station allots the apparatus information signals to time slots in a transmission path and receives a specified apparatus information signal with priority from the respective slave stations. A priority change information signal adder in the master station adds a priority change information signal for changing priority of the information signals transmitted from each slave station to an information transmission signal string containing a sync signal and various information signals transmitted to each slave station. A multi-element information signal separator/processor in the master station separates and processes the multi-element information signals transmitted from each slave station, on the basis of the priority change information signal. A detector/counter in each slave station detects the sync signal transmitted from the master station and counts the number of time slots following the sync signal. A transmission pattern reconstructor in the slave station reconstructs transmission patterns of the respective slave stations in accordance with the priority change information signal when a count value coincides with a predetermined value.
    • 多个从站接收到关于要控制的设备(或传感器)的多个设备信息信号,并且主站将设备信息信号分配给传输路径中的时隙,并且从相应的接收到的优先级接收指定的设备信息信号 从站。 主站中的优先改变信息信号加法器将用于将从每个从站发送的信息信号的优先级改变为包含发送到每个从站的同步信号和各种信息信号的信息发送信号串的优先权改变信息信号。 主站中的多元素信息信号分离器/处理器基于优先级改变信息信号分离和处理从每个从站发送的多元素信息信号。 每个从站中的检测器/计数器检测从主站发送的同步信号,并对同步信号后的时隙数进行计数。 当计数值与预定值一致时,从站中的传输模式重建器根据优先级改变信息信号来重建各个从站的传输模式。
