摘要： PURPOSE:To optimally control the direction of a shield driving machine by inputting the operations of a shield jack, signals from various types of sensors to computers, and analyzing them to predict the future advancing direction and the condition of the shield driving machine. CONSTITUTION:The control system consists of sensors, a underground computer, a measuring computer, and a prediction computer. Data detected by various types of sensors attached to a shield driving machine body are collected in the underground computer, inputted to the measuring computer, calculated, and read out. The measured data are inputted to the prediction computer and analyzed by a statistical technique incorporated in Kalman's filter theory to predict the future advancing course and the position of the shield driving machine. Thus, the prediction accuracy can be improved.

摘要： PURPOSE:To automatically control a shield driving machine by enabling computers to indicate the optimal corrected direction of the shield machine at a real time based on the measured data every moment obtained from a group of sensors in accordance with the change of the field. CONSTITUTION:Detection data every moment obtained from various types of sensors attached to a shield driving machine body are inputted from an underground computer through a surface measuring computer to a control computer. Next, the inputted data are analyzed by the control computer by use of a statistical technique incorporated in Kalman's filter theory in accordance with the change in the ground and the characteristic of the machine. An optical jack- pattern is automatically selected at a real time so that the future advancing direction of the shield driving machine reaches a designed line. Thus, the construction management can be exactly executed.

摘要： PURPOSE:To improve the working management by confirming a present position of a shield driving machine, predicting its future position, and automatically correcting the advancing direction of the machine to the optimal direction by inputting signals from various types of sensors to a computer network. CONSTITUTION:A control mechanism consists of sensors, an underground com puter, a measuring computer, and a control computer. Detection signals from a group of sensors attached to a shield driving machine body are inputted to the underground computer and sent to the measuring computer installed on the ground surface, and then the calculating operation is performed to con firm a present position of the shield driving machine. The calculated values are inputted to the control computer and analyzed by a statistical technique incorporated in Kalman's filter theory. Next, the future advancing direction of the shield driving machine is compared with a designed line and indicated, and a jack patter is automatically selected so that the advancing direction conforms to the designed line in future. Thus, the advancing direction can be optimally controlled.
