Description

  The present invention relates to an article management system for managing an article storage environment, and more particularly, to an article management system for managing an article storage environment by attaching a wireless communication medium to the article.

  Conventionally, strict management of the storage environment is required for articles whose quality is affected by the storage environment, such as food and drink. For example, in the case of alcoholic beverages and frozen foods, management within a predetermined temperature range is required, and various devices have been made for that purpose. For example, in Patent Document 1, RFID (Radio Frequency Identification), which is a wireless communication medium for recording the transition of environmental data, is attached to a box or the like for packaging alcoholic beverages as articles, and recorded in a memory in the RFID. A technology for managing the distribution and storage status of alcoholic beverages based on changes in environmental data is described. In this technology, environmental data in the distribution route of alcoholic beverages is written in a memory in the RFID attached to a box or the like for packing alcoholic beverages, and then written in the memory in the RFID at a liquor delivery destination or the like. By reading out environmental data, the distribution and storage state of alcoholic beverages is managed.

  In addition, when environmental data is written in the memory in the RFID in this way and then the environmental data written in the memory in the RFID is read out, for example, as the RFID, an active battery that has a built-in battery and transmits radio waves by itself Using a type RFID, an access point that reads environmental data transmits a request signal for transmitting environmental data written in the memory to the RFID, and the RFID that has received the request signal transmits the environmental data written in the memory. It is conceivable that the data is read and transmitted to the access point. The access point is connected to an information processing device such as a personal computer via an interface, and environmental data transmitted from the RFID is transmitted to the information processing device via the access point. Will be managed.

Thus, in recent years, RFID capable of reading information in a non-contact state has been used in various fields, and even in the distribution management of goods, environmental data in a distribution channel is written and the environmental data is read out. It is used as such. With RFID that can read information in a non-contact state, it is possible to read information in a non-contact state from a distant location, and it is possible to simultaneously read information from RFIDs attached to multiple items. For this reason, it is possible to improve the efficiency of work for managing articles.

  However, in the one described in Patent Document 1, environmental data in the distribution channel of the article is written in the RFID, and then the environmental data written in the RFID is read out at the delivery destination of the article. When the amount of environmental data to be recorded increases, there is a problem that the RFID memory must have a large capacity. Further, when the amount of environmental data to be recorded is larger, an external memory must be provided in addition to the RFID memory, and there is a problem that the wireless communication medium attached to the article becomes large. In addition, since the environmental data written in the distribution channel is read at a time at the delivery destination of the article, etc., when the RFID has a built-in battery, the battery is greatly consumed when reading the written environmental data. There is a problem that it will.

  Further, as described above, a request signal for transmitting the environmental data written in the memory is transmitted from the access point that reads the environmental data to the RFID, and the RFID that has received the request signal transmits the environmental data written in the memory. When reading and transmitting to the access point, it is necessary to provide the wireless communication medium with a reception function for receiving a request signal transmitted from the access point and a transmission function for transmitting environmental data to the access point, There is a problem that it is difficult to reduce the size of the wireless communication medium attached to the article and simplify the component configuration. In addition, in RFID, in order to receive a request signal transmitted from an access point, it is necessary to always be in a receivable state, so that there is a problem that the battery life is shortened. Further, in an environment where an access point connected to the information processing apparatus is not provided, there is a problem that environment data written in the RFID cannot be read. This is because, for example, when an article is transported by a transportation means such as a truck, the transportation means such as a truck is often provided with an access point connected to an information processing apparatus. Therefore, an access point is provided. Since the environmental data written in the RFID is read out at the delivery destination or the like, the same problem as described above occurs.

  The present invention has been made in view of the problems of the prior art as described above, and is an access point connected to an information processing apparatus when managing a product by attaching a wireless communication medium to the product. It is an object of the present invention to provide an article management system capable of managing articles without enlarging the size of a wireless communication medium or complicating the configuration even in an environment in which no is provided.

  In the present invention configured as described above, the environmental data acquisition means of the wireless communication medium attached to the article acquires environmental data such as the ambient temperature of the attached article at a predetermined timing. Then, each time the environmental data is acquired by the environmental data acquisition means, the acquired environmental data is independently transmitted to the data holding device in the transmission means of the wireless communication medium. In the data holding device, when the environment data transmitted from the wireless communication medium is received by the receiving means, the received environment data is stored and held in the storage means. Thereafter, when the information processing apparatus that manages the environmental data of the article is connected to the output means of the data holding apparatus, the environmental data stored and held in the storage means is output to the information processing apparatus.

  As described above, the environmental data of the article acquired by the wireless communication medium attached to the article is acquired at a predetermined timing, and the acquired environmental data is transmitted every time the environmental data is acquired. Therefore, it is not necessary to provide a reception function for receiving a request signal for transmitting environmental data in the wireless communication medium. Further, when the environmental data of the article is acquired by the wireless communication medium, the environmental data is transmitted to the data holding device and stored / held, so that the acquired environmental data is recorded in the wireless communication medium. In addition, a large-capacity memory and an external memory are not required, and the battery built in the wireless communication medium is not greatly consumed. In addition, when the environmental data acquired by the wireless communication medium is stored and held in the data holding device, and thereafter the information processing device that manages the environmental data of the article is connected to the output unit of the data holding device, the storage unit Since environmental data stored and held in the information processing device is output to the information processing device, articles can be managed without increasing the size of the wireless communication medium even in an environment where an access point connected to the information processing device is not provided. be able to.

  As described above, in the present invention, environmental data of an article acquired by a wireless communication medium attached to the article is acquired at a predetermined timing, and is acquired every time environmental data is acquired. Since the configuration is such that the environmental data is autonomously transmitted from the wireless communication medium to the data holding device, it is not necessary to provide a reception function for receiving a request signal for transmitting the environmental data in the wireless communication medium, and the wireless communication medium is large-sized. The article can be managed without making it complicated or complicating its configuration.

  In addition, since the environment data acquired by the wireless communication medium is transmitted to the data holding device and stored / held, a large-capacity memory is provided to record the acquired environment data in the wireless communication medium. In addition, it is possible to prevent the battery built in the wireless communication medium from being greatly consumed.

  In addition, when the environmental data acquired by the wireless communication medium is stored and held in the data holding device, and thereafter the information processing device that manages the environmental data of the article is connected to the output unit of the data holding device, the storage unit Since the environment data stored and stored in the information processing device is output to the information processing device, the article can be stored without increasing the size of the wireless communication medium even in an environment where an access point connected to the information processing device is not provided. Can be managed.

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

  FIG. 1 is a diagram showing an embodiment of an article management system of the present invention.

  In this embodiment, as shown in FIG. 1, a wireless IC tag 10 with a sensor, which is a wireless communication medium that is attached to an article to be managed and acquires ambient temperature data as environmental data of the attached article, and a wireless IC tag with a sensor The logging device 20 is a data holding device that stores and holds the ambient temperature data acquired at 10 and can output to the information processing device 40 via the external output interface 30.

  The sensor-equipped IC tag 10 is an active RFID that has a built-in power source and transmits radio waves by itself, and includes a power source 18, a temperature sensor 17 and measurement data input unit 14 that are environmental data acquisition means, a power source control unit 13, and the like. The memory 15 is composed of a communication data output unit 12 and a wireless transmission unit 16 which are transmission means. Note that the power supply control unit 13, the measurement data input unit 14, the memory 15, and the communication data output unit 12 are configured by, for example, one chip and are the tag CPU unit 11.

  The temperature sensor 17 measures the ambient temperature and outputs the measured ambient temperature data as an analog value. Thereby, in the state where the wireless IC tag with sensor 10 is attached to the article, the ambient temperature of the article is measured by the temperature sensor 17.

  The power control unit 13 turns on the tag CPU unit 11 and controls power supply from the power source 18 to the temperature sensor 17 and the wireless transmission unit 16 by a watchdog timer function (not shown) of the tag CPU unit 11. .

  The measurement data input unit 14 takes in analog ambient temperature data measured by the temperature sensor 17, converts it into a digital value, and writes it into the memory 15.

  The memory 15 is an overwrite memory, and temporarily stores the ambient temperature data converted into a digital value by the measurement data input unit 14 for each measurement by the temperature sensor 17.

  The communication data output unit 12 outputs the ambient temperature data temporarily stored in the memory 15 as a communication form to the logging device 20.

  The wireless transmission unit 16 wirelessly transmits the ambient temperature data output from the communication data output unit 12 to the logging device 20.

  In addition, the logging device 20 includes a wireless reception unit 26 and a communication data input unit 22 that are reception units, a power source control unit 23, a memory 24 that is a storage unit, a measurement data output unit 25 that is an output unit, and a power source 27. It consists of and. Note that the communication data input unit 22, the power supply control unit 23, the memory 24, and the measurement data output unit 25 are configured by, for example, one chip and are the CPU unit 21.

  The wireless receiver 26 receives the ambient temperature data transmitted from the wireless IC tag with sensor 10 via wireless.

  The communication data input unit 22 writes the ambient temperature data received by the wireless reception unit 26 in the memory 24.

  The power control unit 23 controls power supply from the power source 27 to the wireless reception unit 26.

  In the memory 24, the ambient temperature data received by the wireless receiver 26 is written by the communication data input unit 22, and the ambient temperature data is stored / held by the temperature sensor 17 for a plurality of measurements. It has sufficient capacity to store the ambient temperature data. A separate type such as an SD card may be used.

  The measurement data output unit 25 is configured to be connectable to the information processing device 40 via the external output interface 30, and is stored / held in the memory 24 when connected to the information processing device 40 via the external output interface 30. The ambient temperature data is output to the information processing device 40.

  Hereinafter, an article management method using the article management system configured as described above will be described.

  First, the processing until the logging device 20 stores and holds the ambient temperature data of the article acquired by the sensor-equipped wireless IC tag 10 will be described.

  FIG. 2 is a diagram showing an example of actually managing the ambient temperature of an article using the article management system shown in FIG.

  In this example, as shown in FIG. 2, an article 50 to be transported is accommodated in a container 60, and a sensor-attached wireless IC tag 10 is attached to each of the articles 50. A logging device 20 is installed in the container 60. It is conceivable that the wireless IC tag with sensor 10 is attached to the article 50 by being affixed to the article 50 as a label form or housed in a housing portion provided in the article 50. As long as the logging device 20 can communicate with the sensor-equipped wireless IC tag 10 attached to the article 50, the logging device 20 is not limited to being installed in the container 60 but installed in the driver's seat of a vehicle loaded with the container 60. Is also possible.

  FIG. 3 is a flowchart for explaining the processing until the ambient temperature data of the article 50 shown in FIG. 2 is stored and held in the logging device 20 using the article management system shown in FIG.

  In the tag CPU unit 11 of the sensor-equipped wireless IC tag 10, whether or not it is time to turn the tag CPU unit 11 on is constantly monitored by the watchdog timer function. When it is time to turn on the tag CPU unit 11 (step S1), the tag CPU unit 11 is set to the ON state under the control of the power supply control unit 13, and the temperature sensor is set by the power supplied from the power supply 18. 17 and the wireless transmission unit 16 are activated (step S2).

  When the temperature sensor 17 is activated, the temperature sensor 17 measures the ambient temperature, that is, the ambient temperature of the article 50 attached with the sensor-equipped wireless IC tag 10, and the measured ambient temperature data is measured by the measurement data input unit 14. Captured (step S3). At this time, since the ambient temperature data is output as an analog value from the temperature sensor 17, the ambient temperature data captured by the measurement data input unit 14 is an analog value.

  In the measurement data input unit 14, the ambient temperature data captured as an analog value is converted into a digital value, and the ambient temperature data converted into a digital value is temporarily stored in the memory 15 (step S4).

  Next, in the communication data output unit 12, the ambient temperature data temporarily stored in the memory 15 is read and converted into a communication form to the logging device 20. At this time, in the communication data output unit 12, the unique ID of the sensor-equipped wireless IC tag 10 is given to the ambient temperature data read from the memory 15, and a communication form to the logging device 20 is made.

  Ambient temperature data in the form of communication with the logging device 20 by the communication data output unit 12 is wirelessly transmitted to the logging device 20 via the wireless transmission unit 16 (step S5). At this time, the time stamp function (not shown) of the communication data output unit 12 gives information indicating the transmission time to the ambient temperature data to which the unique ID is assigned, and gives the information indicating the unique ID and the transmission time. The ambient temperature data is wirelessly transmitted to the logging device 20 via the wireless transmission unit 16.

  As described above, in the sensor-equipped wireless IC tag 10, the ambient temperature of the article 50 is measured at a predetermined timing by the watchdog timer function, and the ambient temperature data is independently obtained every time the ambient temperature is measured. Since it is transmitted to the logging device 20, it is not necessary to receive a request signal or the like for transmitting the ambient temperature data to the logging device 20 from the logging device 20.

  Thereafter, in the wireless IC tag with sensor 10, the tag CPU unit 11 is turned off under the control of the power supply control unit 13, and the operations of the temperature sensor 17 and the wireless transmission unit 16 are stopped. 10 enters the sleep mode (step S6). In the power supply control unit 13, the time from when the ambient temperature is measured by the temperature sensor 17 as described above until the ambient temperature data is wirelessly transmitted to the logging device 20 via the wireless transmission unit 16 is set in advance. After the tag CPU unit 11 is turned on and the set time elapses after the temperature sensor 17 and the wireless transmission unit 16 are activated, the tag CPU unit 11 is turned off and the temperature sensor 17 and the wireless communication unit 16 are wirelessly connected. Control is performed to stop the operation of the transmission unit 16. For example, 40 [msec] is set as the time from when the ambient temperature is measured by the temperature sensor 17 until the ambient temperature data is wirelessly transmitted to the logging device 20 via the wireless transmission unit 16. After the unit 11 is turned on and 40 [msec] has elapsed since the temperature sensor 17 and the wireless transmission unit 16 are activated, the tag CPU unit 11 is turned off and the operation of the temperature sensor 17 and the wireless transmission unit 16 is performed. Control to stop is performed.

  In the watchdog timer function of the tag CPU unit 11, timer monitoring is performed so that the above-described processing is repeatedly performed every predetermined time. For example, if the watchdog timer function is set so that an alarm is output every 5 [sec], the control of the power supply control unit 13 is performed every 5 [sec] by this alarm, and the above-described processing is performed 5 times. This is repeated every [sec]. At that time, the ambient temperature data converted into a digital value by the measurement data input unit 14 is overwritten in the memory 15 for each measurement by the temperature sensor 17. That is, only one ambient temperature data measured by the temperature sensor 17 is written in the memory 15, and it is not necessary to make the memory 15 have a large capacity or provide an external memory. .

  Thus, in the sensor-equipped wireless IC tag 10, the ambient temperature is measured every predetermined time, the ambient temperature data is transmitted to the logging device 20, and then the process of setting the sleep mode is repeatedly performed. The consumption of the battery serving as the power source 18 of the sensor-equipped wireless IC tag 10 can be suppressed.

  The ambient temperature data wirelessly transmitted from the wireless transmission unit 16 of the sensor-equipped wireless IC tag 10 is received by the wireless reception unit 26 of the logging device 20 and taken into the communication data input unit 22 (step S7).

  In the communication data input unit 22, when the ambient temperature data received by the wireless reception unit 26 is captured, the captured ambient temperature data is written in the memory 24, and the ambient temperature data is stored / held in the memory 24. (Step S8).

  FIG. 4 is a diagram showing data written to and stored in the memory 24 shown in FIG.

  As shown in FIG. 4, the memory 24 shown in FIG. 1 includes the ambient temperature data measured by the sensor-equipped wireless IC tag 10 and the ID of the sensor-equipped wireless IC tag 10 that is the transmission source of the ambient temperature data. The information indicating the time when the ambient temperature data is transmitted from the sensor-equipped wireless IC tag 10 is stored in association with each other. Since these data are transmitted in correspondence with each other in the communication data output unit 12 of the sensor-equipped wireless IC tag 10 as described above, the communication data input unit 22 recognizes these correspondences. Can do.

  Thus, in the memory 24 of the logging device 20, the ambient temperature data of the article 50 measured by the sensor-equipped wireless IC tag 10 corresponds to the ID of the sensor-equipped wireless IC tag 10 that is the transmission source of the ambient temperature data. Therefore, if the ID of the wireless IC tag with sensor 10 and the article 50 attached with the sensor-attached wireless IC tag 10 are associated with each other and managed in advance, a plurality of wireless IC tags with sensors 10 are stored. It is possible to store the ambient temperature data of the article 50 measured in step 1 so that the article 50 can be specified.

  In the logging device 20 as well, in the power supply control unit 23, as with the wireless IC tag with sensor 10, the CPU unit 21 is turned on and wirelessly transmitted by the watchdog timer function (not shown) of the CPU unit 21. It is also conceivable to control power supply to the unit 26.

  Next, processing until ambient temperature data stored and held in the logging device 20 is managed by the information processing device 40 will be described.

  FIG. 5 is a diagram showing a system configuration example in which the information processing device 40 manages ambient temperature data stored and held in the logging device 20 in the article management system shown in FIG.

  In this configuration example, as shown in FIG. 5, a mobile phone 41 and an article management server 42 are provided as the information processing apparatus 40 shown in FIG. The cellular phone 41 is connected to the measurement data output unit 25 of the logging device 20 via the USB cable 31 serving as the external interface 30, and the article management server 42 can be accessed from the cellular phone 41 via the communication line 43 such as the Internet. It is configured.

  FIG. 6 is a flowchart for explaining processing until ambient temperature data stored and held in the logging device 20 in the article management system shown in FIG. 1 is managed by the article management server 42 shown in FIG. is there.

  In the system shown in FIG. 5, when the ambient temperature data stored and held in the memory 24 of the logging device 20 is managed by the article management server 42, first, the USB cable 31 is connected to the measurement data output unit 25 of the logging device 20. The mobile phone 41 is connected to the mobile phone 41, and the mobile phone 41 is operated to read out ambient temperature data stored and held in the memory 24 of the logging device 20 (step S11).

  Then, the measurement data output unit 25 of the logging device 20 reads the ambient temperature data stored / held in the memory 24 and outputs the read ambient temperature data to the mobile phone 41 via the USB cable 31. (Step S12). At this time, the ID of the wireless IC tag with sensor 10 associated with the ambient temperature data and the information indicating the time when the ambient temperature data was transmitted from the wireless IC tag with sensor 10 are transmitted from the memory 24 together with the ambient temperature data. In the measurement data output unit 25, the ID of the logging device 20 that can identify the logging device 20 is assigned to the information and is output to the mobile phone 41. The ID of the logging device 20 that can identify the logging device 20 is not given to the ambient temperature data when the ambient temperature data is output from the measurement data output unit 25, but from the sensor-equipped wireless IC tag 10. It is also conceivable that the transmitted ambient temperature data is added to the ambient temperature data when it is written to the memory 24.

  After the ambient temperature data output from the measurement data output unit 25 of the logging device 20 is acquired by the mobile phone 41 via the USB cable 31 (step S13), it is acquired from the logging device 20 to the mobile phone 41. When an operation for transmitting the ambient temperature data to the article management server 42 is performed, the ambient temperature data acquired from the logging device 20 by the mobile phone 41 is transmitted to the article management server 42 via the communication line 43 (step S14). ). Even in this case, the ambient temperature data includes the ID of the wireless IC tag with sensor 10 associated with the ambient temperature data, and information indicating the time when the ambient temperature data is transmitted from the wireless IC tag with sensor 10. The ID of the logging device 20 that can identify the logging device 20 is given to the article management server 42 from the mobile phone 41.

  In the article management server 42, when the ambient temperature data transmitted from the mobile phone 41 is received (step S15), the received ambient temperature data is associated with the sensor-equipped wireless IC tag 10 associated with the ambient temperature data. In the article management server 42 with the ID of the logging device 20, the information indicating the time when the ambient temperature data is transmitted from the sensor-equipped wireless IC tag 10, and the ID of the logging device 20 that can identify the logging device 20 being given. (Step S16).

  FIG. 7 is a diagram showing data stored in the article management server 42 shown in FIG.

  As shown in FIG. 7, in the article management server 42, the ambient temperature data transmitted from the mobile phone 41 includes the ID of the wireless IC tag with sensor 10 associated with the ambient temperature data, and the wireless IC tag with sensor. The information indicating the time when the ambient temperature data is transmitted from 10 and the ID of the logging device 20 that can specify the logging device 20 are stored.

  Thus, in the article management server 42, the ambient temperature of the article 50 measured by the sensor-equipped wireless IC tag 10 is managed for each article 50.

  As described above, the ambient temperature data of the article 50 measured by the sensor-equipped wireless IC tag 10 is temporarily stored and held in the logging device 20 for a plurality of measurements in the temperature sensor 17, and then the surroundings of the article 50. When the information processing device 40 that manages the temperature is connected to the logging device 20, the ambient temperature data of the article 50 stored and held in the logging device 20 is output to the information processing device 40. Even in an environment where the device 40 is not provided, the ambient temperature data of the article 50 can be acquired and managed.

  In the configuration example illustrated in FIG. 5, the case where the mobile phone 41 and the article management server 42 are used as the information processing apparatus 40 has been described as an example. However, a general personal computer is used as the information processing apparatus 40. It is also possible. In addition, the external output interface 30 is not limited to the USB cable 31 described above, and an RS-232C cable, a LAN cable, or the like can be used as appropriate according to the type of the information processing apparatus 40.

  Further, when the information processing device 40 is connected to the logging device 20 via the external output interface 30 such as the USB cable 31, the ambient temperature data temporarily stored and held in the logging device 20 is automatically sent to the information processing device 40. It is also possible to adopt a configuration in which the data is transmitted to.

  In the present embodiment, the ambient temperature data of the article 50 measured by the temperature sensor 17 is described as an example of the environmental data. However, the environmental data in the present invention is not limited to this, and the type of the article to be managed. Accordingly, it is conceivable that data relating to humidity, vibration, ultraviolet irradiation, etc. is handled as environmental data, and a sensor for measuring the environmental data is provided in the sensor-equipped wireless IC tag 10.
