    摘要： A contention control system unitarily manages a plurality of data transmissions so as to avoid contention therebetween. Data transmission command sending equipment of a data receiver continuously sends data transmission commands to a data sender according to a data transmission request. Data transmission-command receive control equipment receives the first valid one of the continuously-delivered data transmission commands therein and delivers it to data transmission control equipment. Correspondingly, data sending equipment starts to transmit data. Data transmission monitoring equipment of the data receiver monitors the state of transmission of the data. When the data transmission corresponding to the data transmission commands is made, the data transmission monitoring equipment detects it and notifies the result of detection to data transmission-command transmit control equipment, which in turns terminates the notification of the data transmission commands in response to its notification delivered from the data transmission monitoring equipment. Thus, a reduction in the efficiency of bandwidth utilization at the time that transmission errors are produced in the notification of the above commands can be restrained.
