| titleOfInvention | Automatic control device for digging speed of shield machine |
| abstract | (57) [Summary] [Purpose] To enable automatic adjustment of the excavation speed of the shield machine. [Structure] The drive current supplied to the cutter motor, the pressing pressure of the shield jack, the propulsive force of the shield, the density of the excavated soil in the muddy water, and the rotation speed of the sludge pump are determined by the current detector 3b and the jack pressure sensor 9b. , The propulsion force detection unit 47, the sludge density sensor 29, and the tachometer 31, and these detection results are input to the evaluation score calculation unit 49 of the control computer 45 at predetermined time intervals, and the excavation state of the shield machine 1 is entered. The fuzzy inference unit 55 applies the fuzzy control rule R held in the fuzzy control rule holding unit 57 to perform fuzzy inference based on the calculated evaluation score as an index of Based on the control unit 61 However, the drive of the hydraulic drive source 9a is controlled while monitoring the excavation speed of the shield machine detected by the speed sensor 33. |
