METHOD AND DEVICE FOR RECEIVING, STORING AND DISTRIBUTING THREE-DIMENSIONAL RANGE DATA IN EARTHWORK ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To use processed data from sensors at an earthwork site together with an autonomous machine by requesting and receiving data corresponding to selected information to a data server receiving data from a plurality of sensor systems getting renewal data in accordance with partial variation of an earthwork environment and transmitting the data. SOLUTION: In a device receiving, storing, and distributing data in an earthwork environment, sensor systems 10-12 obtain data of two-dimensional and three-dimensional ranges and images renewed in accordance with the partial change of the earthwork environment by use of a scanning laser, a sonar, rader, and an infrated ray detection technique and transmit these data to the central data server 16 which store a multiplex data packet in a memory. User input means 24-26 constituted of data transmitting/receiving systems transmit questions in which a range that respective users 18, 20, 22 have interests, or a specified space zone of a working site or the like is written and the data server 16 transmits a requested part in the stored data in the memory.
