Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an action data processing system according to the present invention. The configuration and operation of the present embodiment will be described with reference to FIG.

As shown in FIG. 1, the behavior data processing system according to the present embodiment returns a plurality of readers 1 installed in a behavior area for recording behavior data, and returns signals transmitted from each of the readers 1. A plurality of transponders 2
A data processor 4 for statistically processing predetermined data returned from the plurality of transponders 2 and stored in the reader through the network 3 is provided. Here, the action range (survey range) is a building such as a certain factory or department store, a site, a house, or the like.

Note that the first transmitting / receiving means of the present invention is the reader 1
Corresponding to The second transmitting / receiving means of the present invention corresponds to a transponder.

Moreover, each reader 1 includes a signal transmitting / receiving unit 5 for outputting signal change information for generating a signal of a type different from a signal transmitted by another reader.
An RFID unit (a unit for recognizing the presence of a person using a radio signal) 6 for determining the type of a signal returned from the transponder 2 by the reader 1 and a memory for storing a result determined by the RFID unit 6 as data A part 7 is provided.

Next, this will be described in more detail.

As shown in FIG. 1, readers 1a to 1d, which are signal transceivers, are installed at each point (each room, corridor, stairs, toilet, etc.) of a building. Furthermore, a person who acts in the action range walks with the small transponder 2, and the reader 1 receives and records the returned signal. The data stored in the reader 1 is collected by the data processor 4 via the network 3, and the position and speed are calculated and statistically processed.

FIG. 2 shows a block diagram of the reader 1, and FIG. 3 shows the processing procedure.

As shown in FIG. 2, the reader 1 outputs a different signal to the transponder 2 for each reader, receives a reply from the transponder, and transmits data from the memory unit 7 of the reader 1 to the data processor 4 via the network 3. Is provided with a signal transmitting / receiving unit 5 for determining the timing of extracting the behavior data.

The signal transmitting / receiving unit 5 is constituted by, for example, a switching circuit of a dip switch or a switching unit by inserting and removing a ROM. By switching the switches etc. in this unit or replacing the whole unit,
Change the type of outgoing signal.

As described above, the reader 1 changes the signals to be transmitted. For example, since each transmission signal is changed with a frequency, a pulse signal, or the like, the reader 1 can be identified from the viewpoint of the transponder 2, and further, personal information can be recorded on the transponder 2.
You can identify the presence or absence of a person and the individual. The data processor 4 determines the location in the building based on the signal intensity ratio in the signal transmission and reception between the transponder 2 and the reader 1 at this time.

More specifically, the signal strength of the return signal from the transponder 2 is set in advance so as to be proportional to the distance. For example, a case will be described in which the transponder 2 at the position shown in FIG. 1 receives a signal from the reader 1a and transmits a reply signal therefrom. Due to the above-described distance relationship between the transponder 2 and each reader, the ratio of the signal strength of the return signal from each transponder 2 received by each reader decreases in the order of the readers 1a, 1b, 1d, and 1c. Therefore, by storing the relationship between the signal strength ratio of the return signal and the position in the building as data in advance, and comparing with the stored data, the location of the person in the building as described above is obtained. Can be determined.

As shown in FIG. 3, in the reader 1, first,
The signal transmission / reception unit of each reader is set so that each reader outputs a different signal (see steps 1 and 2 in FIG. 3).

Next, the reply from the transponder 2 is received by the RFID unit 5 using the time sharing function. The presence or absence of a signal is used to determine the presence or absence of a person (see step 3 in FIG. 3). When the approach of a person is detected, the action data is stored in the memory unit 7 from the signal transmitting / receiving unit 6 and the RFI
The signal change information of D is read (see step 4). Further, the signal transmitting / receiving unit 5 creates a signal based on the signal change information and outputs the signal to the data processor 4 (see step 5).

As the data processor 4, a personal computer (personal computer) capable of performing statistical processing is used.
This personal computer can be used as a recording medium for storing behavior data, such as a floppy disk, hard disk, magneto-optical disk, or CD.
-R and so on.

The data processing is a processing for calculating an action pattern of each person from data transferred to an electronic computer such as a personal computer. Further, the flow of people in the building such as when and how many people are gathering in each room in the building can be known from all personal data.

FIG. 4 is a flowchart showing processing steps in the data processor 4 of the present embodiment.

Hereinafter, the data processor 4 will be described with reference to FIG.
Will be further described.

That is, when storing the behavior data transmitted in step 5 of FIG. 3, the data processor 4 reads the previously stored data (see step 21).

Further, it is confirmed whether or not the previous and current signal types are the same (see step 22). That is, it is checked whether or not the previous and current recording data are data transmitted from the same reader.

If the result of determination in step 22 is that the signal types are the same, the process proceeds to step 23. Then, in a step 23, it is checked whether or not the signal strength is the same as the previous data.

If the result of the above determination in step 23 is that the signal intensities are different, it can be determined that this means that a person is moving, and the process proceeds to step 24.

In step 24, the previous data is erased and the current recording data is written next to the data two times before.
Therefore, transmission from the same reader (see step 25)
The signal thus obtained is not stored three times in succession, but the action data when approaching the reader for the first time and the action data when leaving the reader are stored. That is, when RFIDs having the same reception strength continue, it indicates that the person was present at that time from time to time.

On the other hand, if the result of determination in step 22 is that the signal types are not the same, the current recording data is written next to the previous recording data (see step 24).

As described above, according to the present embodiment, human behavior data can be obtained in real time, can be easily installed, and the installation of facilities can be easily performed.

The number of readers can be freely increased as long as signals can be identified.

There is no limit on the number of transponders.
For this reason, it is possible to have each person carry the device, and to know the behavior pattern of many people at the same time. In particular, even if many people gather near one reader at the same time, the data can be correctly recorded for all the members.

An optical disk or a magnetic disk on which a program for causing a computer to execute all or a part of the functions of each of the means described above is recorded, and the computer is used by using the optical disk or the magnetic disk. It is also possible to execute the operation. Thereby, the same effect as described above is exerted.

In the above embodiment, the case where the action subject is a human has been described. However, the present invention is not limited to this.
Other moving objects such as animals and living things other than humans may be used.

As described above, according to the present invention, for example, a plurality of readers installed in a range where action data is recorded, a transponder for receiving and returning signals transmitted from each of the readers, A data processor for statistically processing predetermined data stored in the reader through a network, wherein each of the readers receives a radio wave and has a memory unit for sequentially storing the received signals. .

In the first means, for example, in a case where the activity data of a person in this building is measured using a certain building as an activity range, a person who acts in the building has a transponder.

Further, readers for emitting specific signals are arranged at various places in the building. In this reader, the signal processing unit outputs signal information for generating a signal of a type different from a signal transmitted by another transmitter, and the transponder returns a unique signal according to the signal information.

The transponder returns a signal from the reader every time the transponder changes its position according to the action of the carrier, and this signal is stored in the memory unit of the reader. This means that each time the carrier moves and reaches a different range of readers,
Received and written. The storage in the memory unit of the reader does not necessarily need to be digital data.

Then, data is collected from the memory units of the plurality of readers via the network, and the data processor analyzes the signals stored in the memory units and statistically processes the data.

As the second means, in addition to the items specifying the first means, each of the readers respectively has an RFID section for capturing the presence or absence of a person passing within the transmittable range of the signal, and an RFID section for the RFID section. A configuration including a signal processing unit that controls the transmission timing of the signal to the transponder and the data processor based on the output is adopted.

For this reason, in the second means, even if there are a plurality of carriers, the individual can be easily identified only by individually allocating the recording codes of the transponders. In addition, a signal is transmitted only when there is a change in the behavior data in the memory unit, that is, only when the carrier moves, and there is little waste.

As a third means, in addition to the items for specifying the first and second means, a memory unit sequentially stored by the readers obtains the position ratio data obtained through the network from the memory unit by using the intensity ratio of the received signal. A configuration with a function to calculate the current position is adopted.

According to the third means, when the reader receives a signal returned from the transponder, the reader stores the received time in the memory unit. For this reason, in the data processor, the exact position of the carrier is also subjected to statistical processing.

As a fourth means, in addition to the items specifying the third means, a differential value for a certain period of time is obtained from position data obtained through a network from a memory unit sequentially stored by the readers. A configuration having a function of calculating a moving speed is employed.

According to the fourth means, the reader can calculate the moving speed from the time when the signal returned from the transponder is received and the position data, and the exercise amount of the carrier is also subjected to the statistical processing.

As described above, according to the present invention, a plurality of readers are respectively set in an action range for recording action data, and a transponder of a person acting in this action range is transmitted from each of these readers. The data processor receives the signal and stores the determination result in the memory unit based on the returned signal, so the data processor performs a statistical process based on the data stored in each reader, thereby carrying the transponder and carrying out the action. An action pattern can be measured based on the action history of a person who has acted in the range.

Further, since the transponder only needs to have the RFID function, it is easy to set or change the action range, and it is sufficient if the transponder has a function capable of determining the type of the signal from the reader. Therefore, the number of transponders is not limited.

As described above, it is possible to provide an unprecedented excellent behavior pattern measuring apparatus capable of measuring a behavior pattern of a large number of people in a building or a site with equipment that can be easily installed and easily added.

[0062]

As is apparent from the above description, the present invention has an advantage that the behavior data of a plurality of actors in a building or a site can be processed in real time with simpler equipment.
