State surveillance system and method for an object and the adjacent space, and a surveillance system for freight containers

A status surveillance system to survey a movement of an object to be surveyed and a spatial status in the proximate space of said object by a network structure information which is generated by assembling a plurality of communication link statuses, said network being configured by a plurality of wireless communication nodes which are attached to said object to be surveyed,

• wherein said wireless communication node comprises:
• 1) a data communication means to communicate transmission data to other wireless communication nodes;
• and
• 2) a link status detecting means to detect and memorize a link status with other wireless communication nodes.

A status surveillance system to survey a movement of an object to be surveyed and a spatial status in the proximate space of said object by a network structure information which is generated by assembling a plurality of communication link statuses, said network being configured by a plurality of wireless communication nodes which are attached to said object to be surveyed, said status surveillance system further comprising a transmitting means to transmit said network structure information generated at a predetermined time to a surveying center located at a remote location from said object, said network structure information being used as an ID information of said object to be surveyed,

• wherein said wireless communication node comprises:
• 1) a data communication means to communicate transmission data to other wireless communication nodes;
• and
• 2) a link status detecting means to detect and memorize a link status with other wireless communication nodes.

A status surveillance system to survey the inside status of a container during a transportation, comprising:

• a communication network comprising a plurality of communication nodes which are installed randomly or regularly in said container;
• a network structure information generating means to generate a network structure information from a characteristic distribution information of said plurality of communication nodes;
• an initial network structure information recording means to record an initial network structure information of said container to be surveyed, which is generated by said network structure information generating means;
• a monitoring network structure information recording means to record a monitoring network structure information of said container to be surveyed, which is generated by said network structure information generating means in a predetermined time interval;
• a comparison means to compare said initial network structure information recorded in said initial network structure information recording means and said monitoring network structure information recorded in said monitoring network structure information recording means, and output a comparison result;
• and
• a surveillance center to receive said comparison result from said comparison means, wherein, if said comparison result from said comparison means has more than a predetermined deviation, then said surveillance center sends a warning signal to an unloading crane to handle said container with special attention.

A status surveillance method to survey the inside status of a container during a transportation, comprising the steps of:

• installing a communication network comprising a plurality of communication nodes which are installed randomly or regularly in said container;
• generating an initial network structure information from a characteristic distribution information of said plurality of communication nodes at the time of shipping, and recording said initial network structure information;
• recording a monitoring network structure information of an inner space or an object to be monitored installed in said inner space in a predetermined time interval after the container has shipped out;
• comparing said initial network structure information and said monitoring network structure information, and outputting a comparison result, and sending a warning signal to an unloading crane to handle said container with special attention if said comparison result has more than a predetermined deviation.
