Management control device and on-board communication terminal device

An onboard communication terminal device comprising a computer mounted on a manned working machine that travels under operation by an operator, the computer being connected to each of a terminal-side communication device, which is mounted on the manned working machine and includes a wireless communication device, and a GPS mounted on the manned working machine;

• the GPS being configured to calculate a position of the manned working machine and to output position information;
• the terminal-side communication device being connected to a traffic control device, which performs traffic control of an autonomous traveling working machine, via wireless communication network, and being configured to transmit information on a protected region setting request, which requests setting of a protected region for the manned working machine to avoid interference with the autonomous traveling working machine, and the position information to the traffic control device, and to receive response information, which indicates a position of the protected region as set by the traffic control device, from the traffic control device;
• the onboard communication terminal device comprising:
• a vehicle body information storage section that stores vehicle body information indicating a size of vehicle body of the manned working machine,
• a protected region monitoring section that compares the position of the protected region as indicated by the response information and the position information as acquired from the GPS and monitors whether the manned working machine has departed from the protected region, and
• a protected region setting request information generating section that based on results of monitoring by the protected region monitoring section, generates information on a protected region setting request for requesting setting of a new protected region and outputs the protected region setting request information to the terminal-side communication device;
• the protected region including a first protected region, which includes the position of the manned working machine, and a second protected region, which has been set along an outer periphery of the first protected region;
• the first protected region being a region in which the onboard communication terminal device does not transmit new protected region setting request information;
• the second protected region being a region in which the onboard communication terminal device transmits new protected region setting request information;
• the protected region monitoring section including:
• an occupied area calculating section that based on the position information and the vehicle body information, calculates positions of at least two representative points in an occupied area that the vehicle body of the manned working machine occupies on a plane formed by projecting the vehicle body of the manned working machine on a ground surface, and
• a comparison section that compares the positions of the representative points with each of a position of the first protected region and a position of the second protected region;
• and
• the protected region setting request information generating section being configured so that based on results of the comparison by the comparison section, new protected region setting request information is not generated if the occupied area is in the first protected region but new protected region setting request information is generated if the occupied area is in the second protected region.
