Abstract

An input unit inputs detected information that has been acquired by a sensor. By inserting time information into the detected information that has been input, a multiplexer generates an information sequence in which the detected information and the time information are multiplexed in a time-dividing manner. A transmission unit transmits the information sequence. The time information in the multiplexer is used to synchronize timing between detected information included in an information sequence transmitted from another transmitter and the detected information in the multiplexer.

Claims

1. An information analysis system comprising:

a plurality of transmitters; and

a receiver;

wherein each of the plurality of transmitters includes;

an inputting processor that inputs detected information,

a multiplexor that generates an information sequence including the detected information that has been input to the inputting processor and time information that corresponds to the detected information,

a transmitting processor that transmits the information sequence generated by the multiplexor, and

an acquiring processor that acquires time information generated based on a signal from the outside,

wherein, when the acquiring processor acquires the time information, the acquiring processor outputs the time information to the multiplexor,

and, when the acquiring processor fails to acquire the time information, the acquiring processor outputs time information that is generated by updating already-acquired time information to the multiplexor,

wherein the receiver includes;

receiving processor that receives respective information sequences from the plurality of transmitters, and

a processor that analyzes, based on time information included in the plurality of information sequences received by the receiving processor, detected information included in the plurality of information sequences,

wherein each of the plurality of transmitters further includes an imaging device, and

wherein the detected information is image data imaged by the imaging device.

2. An information analysis system comprising:

a plurality of transmitters; and

a receiver;

wherein each of the plurality of transmitters includes;

an inputting processor that inputs detected information,

a multiplexor that generates an information sequence including the detected information that has been input to the inputting processor and time information that corresponds to the detected information,

a transmitting processor that transmits the information sequence generated by the multiplexor,

a generating processor that generates a change tag that shows the magnitude of a change in the value of the detected information that is input to the processor,

a compressor that compresses the information sequence generated in the multiplexor and outputs the information sequence that has been compressed to the transmitting processor,

wherein the multiplexor also multiplexes, in a time-dividing manner, the change tag generated by the generating processor in addition to the detected information and the time information when generating the information sequence, and

wherein the compressor excludes, in the information sequence, at least the change tag from being compressed,

wherein the receiver includes;

a receiving processor that receives respective information sequences from the plurality of transmitters, and

a processor that analyzes, based on time information included in the plurality of information sequences received by the receiving processor, detected information included in the plurality of information sequences,

wherein each of the plurality of transmitters further includes an imaging device, and

wherein the detected information is image data imaged by the imaging device.

3. The information analysis system according to claim 2, wherein the multiplexor changes an interval for inserting time information based on the type of the detected information that is input to the processor.

4. The information analysis system according to claim 2, wherein the multiplexor changes an interval for inserting time information based on a change in the value of the detected information that is input to the processor.

5. An information analysis system comprising:

a plurality of transmitters; and

a receiver;

wherein each of the plurality of transmitters includes;

an inputting processor that inputs detected information,

a multiplexor that generates an information sequence including the detected information that has been input to the inputting processor and time information that corresponds to the detected information, and

a transmitting processor that;

transmits the information sequence generated by the multiplexor to a transfer device that is also capable of receiving an information sequence from another transmitter, and

wherein, in the transfer device, priority is set to each of the plurality of transmitters, and an information sequence from a transmitter with high priority is referentially transmitted,

wherein the receiver includes;

a receiving processor that receives respective information sequences from the plurality of transmitters, and

a processor that analyzes, based on time information included in the plurality of information sequences received by the receiving processor, detected information included in the plurality of information sequences,

wherein each of the plurality of transmitters further includes an imaging device, and

wherein the detected information is image data imaged by the imaging device.
