    • PURPOSE:To reduce the power consumption and to compensate the communication error due to interference or the like to surely periodically transmit data by performing the intermittent operation and performing transmission or reception plural times at the time of intermittent operation with respect to the communication equipment for radio data communication between a gas meter or a water meter and a remote measurement gage check device CONSTITUTION:This equipment consists of a data transmission equipment consists of a data transmission equipment 2 and a data reception equipment 9. The data transmission equipment 2 is provided with an intermittent transmission control part 6, which is started by a transmission timer part 7 and repeats transmission at intervals of a certain time, and a transmission stop part 16 which stops the operation of the intermittent transmission control part 6 on conditions of the frequency in transmission, the time, etc. The data reception equipment 9 is provided with an intermittent reception control part 13, which is started by a reception timer part 14 and repeats reception at intervals of a certain time, and a reception stop part 18 which stops the operation of the intermittent reception control part 13 on conditions of the frequency in reception, reception of time data, etc.

    • PURPOSE:To surely attain synchronization between transmission and reception and to suppress increase in a synchronization matching interval by deviating a transmission reception timing by a random time when a disturbing signal is in existence in the transmission reception timing for each time interval of Tsec. CONSTITUTION:Upon the receipt of disturbance at the transmission reception of a synchronization matching signal for each interval T2, a transmission communication equipment 29 sends a synchronization matching signal in a succeeding timing T1. When reception is disable in the timing T1, an intermittent control means 22 of a reception communication equipment 23 makes reception for plural number of times for an interval shorter than a bit synchronization interval and detects a synchronizing signal in any reception timing. Then the synchronization is matched in a timing when the synchronizing signal is detected and a prescribed communication mode is set. Thus, a timing when disturbance takes place is avoided early.
    • 目的:为了确保在发送和接收之间达到同步,并且通过在Tsec的每个时间间隔的发送接收定时中存在干扰信号时的随机时间偏移发送接收定时,抑制同步匹配间隔的增加。 构成:在每个间隔T2的同步匹配信号的发送接收中接收到干扰时,发送通信装置29在后续的定时T1发送同步匹配信号。 当在定时T1中禁止接收时,接收通信设备23的间歇控制装置22以比同步间隔短的间隔进行多次接收,并且在任何接收定时检测同步信号。 然后,在检测到同步信号并设定规定的通信模式的定时,同步被匹配。 因此,尽早避免发生干扰的时机。
