Moving body information transmission device and moving body monitoring system using same

An information transmission device installed in a moving body, comprising:

• a communication section that performs wireless communication with a base station on a ground side;
• a position detection section that detects current position of the moving body;
• a zone information storage section that stores zone information indicating a predetermined zone that includes a zone in which the wireless communication cannot be performed;
• an operation mode determining section that periodically determines, based on the current position and the zone information, whether an operation mode relating to transmission from the communication section to the base station is to be a first operation mode or a second operation mode, wherein the operation mode determining section determines the first operation mode when the current position is within the predetermined zone and determines the second operation mode based on a necessary condition that the current position is outside the predetermined zone;
• an attribute assigning section that, when the operation mode determining section determines the first operation mode, assigns an attribute, indicating that new information should be transmitted later, to the new information that is not yet targeted for processing in the first operation mode or for processing in the second operation mode among information collected in time series in the moving body;
• a communication control section that, when the operation mode determining section determines the second operation mode, controls the communication section so that the new information, which is not yet targeted for processing in the first operation mode or for processing in the second operation mode among the information collected in time series, and at least a part of the information to which the attribute is assigned are transmitted to the base station;
• and
• an attribute canceling section that cancels the attribute, which is assigned to the at least part among the information to which the attribute is assigned, after the transmission of the information.
