  The IC card 5 is a non-contact type IC card in which an IC chip is embedded, and its block configuration is the same as that of the RF tag 1 shown in FIG. Further, a program for operating the IC card is stored in the ROM of the storage unit 16 of the IC card 5, and IC card identification information assigned to each IC card is stored in the EEPROM.

  In the above configuration, the processing of the CPU 10 of the RF tag 1 will be described. The RF tag 1 is supplied with power by the power of a radio signal transmitted from the reader / writer 2. The CPU 10 of the RF tag 1 starts the processing shown in FIG. 5 when the product is displayed on the product shelf and the power is supplied by the power of the radio signal periodically transmitted from the reader / writer 2.

  First, it is determined whether or not a radio signal from the reader / writer 2 is received by the antenna 13c (S100).

  Here, when the radio signal from the reader / writer 2 is not received, power is not supplied to the RF tag 1 itself, so the determination of S100 is not actually performed, but until the wireless signal from the reader / writer 2 is received, Assume that the determination in S100 is performed.

  In S100, when a radio signal from the reader / writer 2 is received, the received radio signal is amplified and frequency-converted by the radio receiver 13b, and further demodulated and A / D converted by the demodulation circuit 12b. The signal according to the reception level is input to the CPU 10. In addition, this signal includes read / writer identification information RWi and time information Ti for identifying the read / writer 2.

  Next, it is determined whether the customer has picked up the product displayed on the product shelf or the like. When the product displayed on the product shelf or the like is moved by the customer, the distance between the RF tag 1 attached to the product and a specific reader / writer 2 provided in the vicinity of the RF tag 1 changes, and the RF tag The reception level of the radio signal 1 received from the specific reader / writer 2 changes. Therefore, based on the reception level of the wireless signal, it is detected whether or not the product displayed on the product shelf has moved.

  That is, the reception level of the radio signal from the reader / writer 2 is a radio signal from a specific reader / reader provided in the vicinity of the RF tag 1 or a radio signal from a reader / driver farther away from the specified reader / writer. A first threshold level LV1 for determining whether the product is displayed and a second threshold level LV2 for determining whether the product is in a displayed state or a moved state are defined in advance. Whether the product has moved based on whether the reception level of the radio signal from the reader / writer 2 is higher than the first threshold level LV1 and lower than the second threshold level LV2, that is, , It is determined whether the customer has picked up the product.

  If the reception level of the radio signal from the reader / writer 2 is smaller than the first threshold level LV1, the radio signal from the reader / writer 2 is regarded as noise and is not recognized. In addition, in the state where the product is displayed, the distance between the product and the specific reader / writer 2 is short, the reception level of the radio signal from the reader / writer 2 is higher than the second threshold level LV2, and the product is displayed. It is determined that it is in a state. (S102).

  If it is determined that the customer has not picked up the product (determined as N in S102), the process returns to S100.

  In S102, when it is determined that the customer has picked up the product (determined as Y in S102), the product identification information PRi is added to the reader / writer identification information RWi and the time information Ti included in the wireless signal received in S100. The added reply data is generated (S104).

  Then, the reply data generated in S104 is transmitted from the antenna 13c (S106).

  Next, based on whether or not a signal indicating that the product has been settled is received from the POS 4, it is determined whether or not the product has been settled at the POS 4 (S108).

  Here, when it is determined that the product is not settled in POS4, the process returns to the determination in S102, and the processes in S100 to S108 are repeated.

  If it is determined in S108 that the product has been settled at POS4, the function as the RF tag is stopped (S110).

  Next, the processing of the CPU of the IC card 5 will be described with reference to FIG. Similar to the RF tag 1, the IC card 5 is supplied with power by the power of the radio signal transmitted from the reader / writer 2. The IC card 5 is owned by the customer and moves with the customer. Further, the CPU of the IC card 5 starts the process shown in FIG. 6 when the power is supplied by the power of the radio signal periodically transmitted from the reader / writer 2.

  First, it is determined whether a radio signal from the reader / writer 2 has been received. The radio signal from the reader / writer 2 includes the reader / writer identification information RWi and time information Ti, which are identification information given to the reader / writer 2 (S200).

  Next, reply data in which the IC card identification information Ici is added to the reader / writer identification information RWi and the time information Ti included in the wireless signal received in S200 is generated (S204).

  Then, the reply data generated in S204 is transmitted (S206).

  Next, based on whether or not a signal indicating that the product has been settled is received from the POS 4, it is determined whether or not the product has been settled at the POS 4 (S208).

  Here, when it is determined that the product is not settled in POS4, the process returns to the determination in S200, and the processes in S200 to S208 are repeated.

  If it is determined in S208 that the product has been settled in POS4, this process ends.

  Next, with reference to FIG. 7, the processing of the CPU 20 of the reader / writer 2 and the processing unit of the management server 3 will be described. Note that the processing of the CPU 20 of the reader / writer 2 and the processing of the processing unit of the management server 3 will be described as processing of the same processing unit. When the power is turned on, the CPU 20 of the reader / writer 2 and the processing unit of the management server 3 perform a predetermined initialization process and then perform the process shown in FIG.

  First, a radio signal is periodically transmitted from the transmission antenna 23c of the reader / writer 2. This radio signal is received by both the RF tag 1 and the IC card 5. In addition, this wireless signal includes read / writer identification information RWi and time information Ti, which are identification information given to the read / writer 2 (S300).

  Next, the wireless signal transmitted from the IC card 5 in S206 of FIG. 6 is received, and information included in the wireless signal is stored in the database of the storage device 3a. In addition to the reader / writer identification information RWi and time information Ti transmitted in S300, IC card identification information Ici for identifying the IC card 5 is added to this radio signal (S302).

  Next, the wireless signal transmitted from the product RF tag 1 in S106 of FIG. 5 is received, and the information included in the wireless signal is stored in the database of the storage device 3a. The radio signal includes product identification information PRi for identifying the product in addition to the read / writer identification information RWi and time information Ti transmitted in S300. (S304).

  Next, based on the radio signal received from the IC card 5, the customer position is calculated (S310). In FIG. 8, the flowchart of the calculation process of the customer position by CPU20 of the read / dryer 2 is shown.

  First, since a plurality of radio signals are received from the IC card 5 or the RF tag 1 existing in the store by the receiving antenna 23d of the read / dryer 2, the reception of the read / reader 2 is avoided in order to avoid collision of these radio signals. A known anti-collision (collision avoidance) process is performed on the radio signal received by the antenna 23d, and then a noise process for removing noise is performed (S311).

  Based on the signals subjected to these processes, the position of the IC card 5 is calculated by three-point surveying (S308).

  Next, returning to the description of FIG. 7, it is determined whether or not an abnormal data pattern is detected from a database stored as a database in the storage device 3 a of the management server 3.

  As the abnormal data pattern, for example, when the customer is in a certain place for a predetermined reference time or more, or when the customer circulates within a predetermined range for a predetermined reference time or more, it is predetermined by the customer. For example, when a product exceeding the amount of money or the number of products is selected, an unsettled product is moved to the toilet or near the exit by the customer.

  If the customer is in a certain place for a predetermined reference time or more, or if the customer is traveling within a predetermined range for a predetermined reference time or more, it is estimated that the customer is in trouble with product search it can. In addition, when a product that exceeds a predetermined amount or number of items is selected by the customer, if an unsettled product is moved to the toilet or near the exit, suspicious behavior such as theft can be estimated.

  As described above, when an abnormal data pattern is detected, for example, the display screen of the management server 3 is displayed in real time to indicate that there is an abnormality, and a sound indicating the abnormality is output from the speaker to Notification is made (S320).

  Next, when information indicating that the product has been settled from POS4 is input, the customer's purchase trajectory such as the movement trajectory of the customer, whether or not the product has moved by the customer, and the product settled by POS4. The information is associated and stored in the storage device 3a as a database. And the process of S300-S310 is repeated.

  In addition, the information regarding the product settled by the POS 4 includes a product ID transmitted from the RF tag 1 and information indicating that the product is finally purchased.

  FIG. 9 shows an example of a database structure in the storage device 3 a of the management server 3. As shown in the figure, is the database purchased purchasing action ID, time, ID, location, finally purchased? Such items are stored.

  As the ID, identification information such as IC card identification information Ic1 and Ic2 and product identification information PR1 and PR2 is stored. Each position item of the IC card identification information Ic1 and Ic2 stores the position calculated by the position calculation processing of the IC card 5, and each position item of the product identification information PR1 and PR2 contains the item of the displayed product. The position is stored in advance by an operator's input operation, or the position calculated by communication with the reader / reader immediately before the reception level exceeds LV2 in S102 at the time of display. In addition to the information shown in FIG. 9, information indicating whether the product has been moved by the customer is also stored.

  Here, for example, when the customer who owns the IC card 5 that transmits the IC card identification information Ic1 examines the product with the RF tag 1 that transmits the product identification information PR1 by hand, the IC card identification information Ic1 The positions of the product identification information PR1 are almost the same. Furthermore, when the customer puts this product in the shopping cart and moves, each position of the IC card identification information Ic1 and the IC card identification information Ic1 follows the same movement locus. Thus, the same purchase behavior ID is assigned to what can be regarded as the purchase behavior of the same customer from the correlation between the movement trajectory of the customer and the product.

  As described above, the customer comprising the IC card 5 that moves with the customer and transmits a wireless signal, and the management server 3 having the storage device 3a that stores the movement trajectory of the customer based on the wireless signal from the IC card 5. The trend survey system detects that the product has been moved by the RF tag 1 attached to the product, and the storage device 3a is information indicating that the product detected by the RF tag 1 has been moved together with the movement trajectory of the customer. Therefore, it is possible to provide a customer trend survey system that investigates information on how a customer moves in the store and which product the customer has examined.

  In this way, not only information related to the product purchased by the customer, but also purchase behavior characteristic information of the customer such as the movement trajectory of the customer and selection behavior of the product by the customer is collected and managed as a database in the storage device 3a of the management server 3. The

  If information that the customer has not purchased the product but the customer has picked up the product is extracted from the information stored as a database in the storage device 3a of the management server 3, interest in the product is high. Can be estimated. Further, when information indicating that the customer has picked up a plurality of products is extracted, it is also possible to extract information such as which products the customer has purchased by comparing a plurality of products.

  In addition, when an abnormal data pattern is detected from information stored as a database in the storage device 3a of the management server 3, it is estimated that the customer is having trouble finding a product or suspicious behavior by the customer, You can report.

  In this way, customer purchase behavior characteristic information such as the customer's movement trajectory and the customer's product selection behavior is collected and managed as a database in the storage device 3a of the management server 3. Then, it is possible to provide a large amount of high-quality customer purchase behavior characteristic information.

  The purchase behavior characteristic information of the customers collected and managed in this way is utilized as marketing information in stores, headquarters or suppliers, etc., and is used for improving product development capability, customer service improvement, and sales capability.
