Abstract:
A status notification system for automatically wirelessly communicating status information supplied from a plurality of sensors installed on said movable body, comprising:a status sensing unit for transmitting predetermined data to said response unit through said communication unit when said movable body has a predetermined status based upon data obtained from said plurality of sensors and for selectively transmitting said data obtained from said plurality of sensors when an additional information transmission request is received from said response unit through said communication unit; a response unit; a communication unit for wirelessly communicating with said status sensing unit and for communicating with said response unit, wherein said response unit receives said predetermined data from said status sensing unit through said communication unit, determines whether an acquisition of said additional information is necessary based upon said predetermined data, and requests said transmission of said additional information from said status sensing unit when said acquisition of said additional information is necessary; said status sensing unit having: input means for inputting sensing information sensed from said plurality of sensors; storage means for storing said sensing information inputted by said input means; sensing means for sensing whether said sensing information is within a predetermined range; first communication means for wirelessly communicating with said response unit; and first control means for selecting predetermined sensing information from said sensing information stored in said storage means when said movable body having said sensing unit is in said predetermined status, for controlling said first communication means to wirelessly transmit said selected sensing information to said response unit, and for reading said requested additional information from said storage means to transmit said read additional information when said acquisition request is received from said response unit; said communication unit having: wireless communication means for wirelessly communicating with said status sensing unit; network communication means for communicating with said response unit connected to said network; and conversion means for converting a data format of said wireless communication and a data format of said network communication; and said response unit having: second communication means for communicating with said status sensing unit through said network; evaluation means for evaluating said status of said movable body having said status sensing unit from said predetermined sensing information supplied from said status sensing unit; and second control means for controlling said second communication means to transmit acquisition request information for requesting said additional information to said status sensing unit when said additional information request is necessary based upon an evaluation result from said evaluation means.
