Description

  The present invention provides a route for managing the passing route of visitors by writing data to IC tags held by the attendees in a plurality of recording devices installed in the venue at an event venue such as an exhibition or orienteering. Regarding the management system.

  Conventionally, a system for lending an IC tag to a visitor to such a facility in an art museum or a museum, and acquiring the browsing history of the exhibit viewed by the visitor using the rented IC tag has been proposed. It is used for facility management.

In this proposed system, a tag reader for reading an IC tag is installed at the entrance / exit of the venue, while an IC tag reader / writer (hereinafter referred to as R / W) is installed in front of each exhibit in the facility. A flag corresponding to each exhibit is provided in advance in the data area of the IC tag. When an attendee browses the exhibit, the IC tag is held over the R / W, and the flag of the corresponding exhibit is displayed. When the IC tag is set and the IC tag is placed over the tag reader installed at the entrance when the entrant leaves, the flag state is read by the tag reader. As described above, since the browsing history of the visitor possessing the IC tag is written in the IC tag, the administrator does not need to collect information from the R / W side, and connects the R / W in the facility. It is possible to acquire the visitor's browsing history at the entrance / exit without constructing a network for the purpose (see, for example, Patent Document 1).
JP 2002-259611 A

  However, in the proposed system, the browsing history of the exhibit is written in the IC tag by setting a flag for each exhibit provided in advance in the IC tag, so that information on the viewed exhibit is acquired. For example, in a large event venue where the route is not specified in advance, it was not possible to grasp the browsing route such as what route the viewer went through and viewed each exhibit. .

  The present invention has been made in view of these problems, and an object of the present invention is to provide a route management system that manages the passage route of facility users in facilities such as event venues and museums where entrance is managed. And

  The invention according to claim 1, which has been made in order to achieve such an object, is distributed and installed in a facility to be managed, and an IC possessed by the facility user when the facility user passes near the installation location. A plurality of recording devices that write data to a tag, and a management device that is installed at an entrance / exit of the managed facility and reads data from an IC tag possessed by the facility user when the facility user passes through the entrance / exit A route management system for managing a passage route of a facility user in the management target facility, wherein the recording device performs data communication between a time measuring unit for measuring a current time and the IC tag. Thus, the writing means capable of writing data to the IC tag, the first detection means for detecting the passage of the facility user near the installation location, and the passage of the facility user by the first detection means. When detected, the timekeeping First control means for reading the current time from the stage, generating time data comprising the current time and identification information of the recording device, and writing the generated time data to the IC tag via the writing means; The management device comprises: a reading unit capable of reading data from the IC tag by performing data communication with the IC tag; and a second detection unit detecting passage of a facility user at the entrance / exit When the second detection means detects the passage of the facility user, the identification information pre-registered in the IC tag is written by the respective recording devices from the IC tag via the reading means. And second control means for reading the time data and storing it in the storage means.

  As described above, in the route management system of the present invention, when the first detection unit detects the passage of the facility user near the installation location in the recording apparatus distributed and installed in the management target facility, the first control unit Reads the current time measured by the time measuring means, generates time data from the current time and the identification information of the recording device, and writes the generated time data to the IC tag via the writing means. Further, in the management apparatus installed at the entrance / exit of the facility to be managed, when the second detection means detects the passage of the facility user at the entrance / exit, the second control means changes the IC tag from the IC tag via the reading means. The identification information registered in advance and the time data written by each recording device are read and stored in the storage means.

  For this reason, according to the route management system of the present invention, the manager managing the facility reads a plurality of time data including the current time and the identification information of the recording device read from the IC tag possessed by the facility user at the entrance / exit. Thus, the facility user can grasp and manage the route that has passed through the facility.

  The path management system according to claim 1 is configured to count the elapsed time from a reference time predetermined for each recording apparatus and management apparatus as the current time, as described in claim 2. May be.

  In other words, the absolute time at that time may be measured as the current time, but in order to represent 24 hours in seconds, a data length of 17 bits is required, and the capacity of the data area of the IC tag is insufficient. The number of time data that can be written may be insufficient. However, as described in claim 2, when the elapsed time is counted as the current time, the elapsed time can be made shorter than 24 hours by setting the reference time, so the data length of the data representing the current time is shortened. . For this reason, the data length of the time data written by the recording device is shortened, and more time data can be written to the IC tag.

  According to a second aspect of the present invention, the route management system according to the second aspect is the initial value for the time measuring means to measure the elapsed time from the reference time according to the command inputted from the outside to the recording device. There may be provided an initial value setting means for setting.

  That is, in each recording device, it is possible to simultaneously start timekeeping by the timekeeping means and measure the elapsed time using this time as a reference time, but in this way, a device for performing wireless communication with the recording device is provided. It is necessary to provide it. However, according to the third aspect of the present invention, even if the timing of starting the timing in the time measuring means of each recording device is not the same, by inputting the elapsed time from the reference time at that time as an initial value, Since the elapsed time from the reference time is measured based on the initial value, it is possible to set the initial value while sequentially turning each recording apparatus, and to measure the elapsed time from the reference time, which is convenient.

  Furthermore, when the route management system according to claim 2 or 3 reads the elapsed time and the identification information as time data as described in claim 4, the second control means And a time at which the recording device reads the current time from the time measuring means from a predetermined reference time, and the calculated time and identification information are stored in the storage means as time data. Also good.

  In this way, since the absolute time when the facility user is detected by the recording device is calculated and stored in the management device, the administrator can set the time data including the elapsed time as the absolute time. There is no need to perform an operation for conversion, which is convenient.

  Next, in the fifth aspect of the invention, in the route management system according to any one of the first to fourth aspects, when the passage of the facility user is detected by the first detection means, Based on the current time read and the time data already written in the IC tag, time difference data representing the time from the time when the previous time data was written in the IC tag is generated. If the data length is longer than a predetermined value, first time data is generated by adding an identification header indicating the data length to the current time and identification information, and the data length of the time difference data is predetermined. If shorter than the value, data for generating second time data having a shorter data length than the first time data in which the identification header indicating the data length is added to the time difference data and the identification information When the data generating means is provided with the generating means and the data generating means generates the data, the first control means uses the first time data or the second time data as the time data of the recording apparatus via the writing means. And writing to the IC tag.

  Depending on the number of recording devices passed by the facility user, the capacity of the data area of the IC tag may be insufficient, and the number of time data that can be written may be insufficient. According to the invention of claim 5, When the time difference data is shorter than the predetermined data length, the second time data shorter than the first time data is generated based on the time difference data and the identification information. The situation in which the second time data having a short data length is written increases, and more time data can be written to the IC tag.

  Further, in the route management system according to claim 5, when the identification information of the recording device is composed of an identification number and the data generation means generates a time difference data shorter than a predetermined value, When the identification number difference is calculated from the identification number of the recording apparatus that has written the data and the identification number of the recording apparatus, and the data length of the identification difference data that represents the difference between the identification numbers is longer than a predetermined value When the first time data with the identification header added to the current time and the identification number is shorter than a predetermined value, the data length is longer than the first time data with the identification header added to the time difference data and the identification difference data. The second time data having a short time may be generated.

  In this way, since the second time data having a short data length is generated only when the data representing the difference between the current time and the identification number is shorter than a predetermined value, the second time data is made shorter. More time data can be written to the IC tag in accordance with conditions such as the installation interval of the recording device and the setting of the identification number.

Embodiments of the present invention will be described below with reference to the drawings.
1A is a schematic configuration diagram showing the configuration of a path management system to which the present invention is applied, FIG. 1B is a block diagram showing the configuration of the management device 10, and FIG. 1C is a recording device. It is a block diagram which shows the structure of 50. FIG.

  In the route management system of this embodiment, as shown in FIG. 1A, the venue is divided into a plurality of zones, and in the orienteering venue where a plurality of checkpoints are provided for each zone, the orientation management is performed at the reception. The IC tag 2 lent to the participant is used to manage the movement route of the participant in the venue, and is installed at the reception of the venue and management for reading the data written in the IC tag 2 The apparatus 10 includes a plurality of recording devices 50 that are installed at each check point and write a time log indicating that the IC tag 2 has been detected to the IC tag 2.

  In this embodiment, each checkpoint provided in the same zone of the orienteering venue is arranged so that the travel time between checkpoints is within 30 minutes, and each checkpoint in the same zone The recording device 50 installed at the point is set with an identification number so that the difference between the identification numbers is 7 or less.

  As shown in FIG. 1B, the management apparatus 10 of this embodiment includes a management terminal 20 composed of a personal computer (hereinafter referred to as a personal computer) and an IC tag reader / writer 12 (hereinafter referred to as R / W 12) connected to the management terminal 20. The management terminal 20 is configured to be able to send and receive data to and from the IC tag 2 via the R / W 12.

  The management terminal 20 includes a control unit 22 including a CPU, RAM, ROM, timer, and the like, a memory 24, an operation unit 26 including a keyboard and a mouse, a display unit 28 including a display, and the control unit 22 includes an operation unit 26. In response to the command input from the above, various processes such as display of data stored in the memory 24 on the display unit 28, data aggregation, and reference time setting are executed.

  Further, when the IC tag 2 is held over the R / W 12 and the IC tag 2 is detected by the R / W 12, the control unit 22 writes the ID of the detected IC tag 2 and each recording device 50. A plurality of time logs are read out via the R / W 12 and stored in the memory 24.

  On the other hand, as shown in FIG. 1C, the recording apparatus 50 includes a control unit 54 composed of a microcomputer including a CPU, RAM, ROM, timer, etc., an IC tag reader / writer 52 (hereinafter referred to as R / W 52), a connector, The external I / F 56 is configured to be capable of transmitting / receiving data to / from the IC tag 2 via the R / W 52.

  An external device such as a personal computer can be connected to the recording apparatus 50 via the external I / F 56. When time is input from the connected external device, the control unit 54 receives the input. The time is set as an initial value for measuring the elapsed time from the reference time, and the elapsed time from the reference time is measured by the built-in timer based on the initial value (in the initial value setting means in the present invention). Equivalent to).

  Further, when the IC tag 2 is held over the R / W 52 and the IC tag 2 is detected by the R / W 52, the control unit 54 reads and reads the past time log already written in the detected IC tag 2. Based on the past time log, the elapsed time measured by the timer, and the identification number of the recording device 50, a time log in the recording device 50 is generated, and this time log is connected to the IC tag 2 via the R / W 52. Write to.

  The R / W 12, 52 is a non-contact IC reader / writer capable of reading and writing information with respect to the IC tag 2 separated by several tens of centimeters. The IC tag 2 transmits the wireless transmission power from the R / W 12, 52. The tag is provided with a function for starting and wirelessly transmitting information and having a rewritable user area by incorporating a memory such as an EEPROM.

2A and 2B are configuration diagrams showing the configuration of the time log generated by each recording device 50, and FIG. 2C is an example of data written in the storage area of the IC tag 2. FIG.
The time log is configured based on the identification number of the recording device 50 and the elapsed time from the reference time, and the past time log already written in the detected IC tag 2 in each recording device 50, and the recording Depending on the relationship between the identification number of the device 50 and the elapsed time, one of two types of time logs of type A or type B having different data lengths is generated.

  More specifically, assuming that the nth checkpoint is the checkpoint that the participant has passed through the nth checkpoint, and the recording device 50 installed at this checkpoint is the nth recording device 50, from the (n-1) th checkpoint. The time until the nth check point is reached, that is, the n-1 elapsed time measured by the n-1 recording device 50 and the nth elapsed time measured by the nth recording device 50. When both the time difference data representing the time difference and the identification difference data representing the difference between the identification number of the (n-1) th recording device 50 and the identification number of the nth recording device 50 are shorter than the predetermined data length, A time log is generated, otherwise a type A time log is generated.

  In the present embodiment, when the participant has moved from a checkpoint in the same zone, as described above, the difference in elapsed time is within 30 minutes, and the difference in identification numbers is 7 or less. . For this reason, the type B time log is generated in the case of movement within the same zone, and the type A time log is generated in the case of movement between zones. 11 bits that can record a value between 2047 seconds (about 34 minutes) and the default data length of the identification difference data are set to 4 bits that can be recorded with a value between -7 and 7, respectively. .

  Then, as shown in FIG. 2A, the type A time log is recorded by an identification header (value 0) indicating type A, data indicating the identification number of the recording device 50, and the recording device 50. And the data length of the identification header, the identification number, and the elapsed time are set to 1 bit, 6 bits, and 17 bits. For this reason, a value between 1 and 64 as the identification number and 0 to 131071 seconds (about 36 hours) as the elapsed time can be recorded, and the type A time log is composed of 24 bits (3 bytes) as a whole. ing.

  On the other hand, as shown in FIG. 2B, the type B time log includes an identification header (value 1) indicating type B, the above-described identification difference data and time difference data, and data of the identification header. The length is 1 bit, and each data length of the identification difference data and the time difference data is set to 4 bits and 11 bits, which are the same as the predetermined data length, so that data less than the predetermined data length can be recorded. For this reason, the type B time log has a total of 16 bits (2 bytes), and is configured to be able to handle writing in byte units in the same manner as the type A time log.

  Next, the configuration of data stored in the storage area of the IC tag 2 will be described. The storage area of the IC tag 2 is composed of a rewritable user area as shown in FIG. 2C and an area in which the ID of the IC tag 2 is recorded and which is not permitted to be rewritten.

  In the IC tag 2 used in the present embodiment, for example, as shown in FIG. 2C, the user area is divided into 4-byte blocks, and the user area has a total of 128 bytes. By holding the IC tag 2 over the recording device 50, time logs are written in order from the first block. Here, since the identification header of type A time log is 0, the data length is 3 bytes, the identification header of type B is 1 and the data length is 2 bytes, the user area is read in order from the first block. Thus, each time log can be disassembled and read for each recording device 50 in which the time log is written.

  For example, in the data shown in FIG. 2C, since the first bit is 0, the first time log (1) written by the first recording device 50 is identified as type A, It is determined that the subsequent 3-byte area including the identification header is data written in the first recording device 50. Similarly, since the subsequent bit is 1, the subsequent 2 bytes including the identification header are the second time log (2) of type B written by the second recording device 50, and the subsequent bits are Therefore, the subsequent 2 bytes including the identification header are identified as the type B third time log (3) written by the third recording device 50.

  Below, the procedure of the time recording process which the control part 54 of the recording device 50 performs is demonstrated using FIG. FIG. 3 is a flowchart showing the time recording process, and shows the process of the control unit 54 of the nth recording apparatus 50 in which the participant has passed the nth time.

  The time recording process is a process that is repeatedly executed by the control unit 54 while orienteering is held. When the process is started, the IC tag 2 is first detected by the R / W 52 in S100. It is determined whether or not. If the IC tag 2 is not detected (S100: NO), the process of S100 is repeated.

  On the other hand, when the IC tag 2 is detected (S100: YES), the process proceeds to S110, where all of the detected ID of the IC tag 2 and past time logs written in the user area are read. Transition. In S120, it is determined whether or not the past time log can be read in S110, that is, whether or not the past time log is saved in the user area, and the past time log is saved. If it is, that is, if it is not the first check point (S120: YES), the process proceeds to S130.

  In S130, the past time log read in S110 is identified by the identification header in order from the first block, and it was set at the last saved time log, that is, the checkpoint where the participant passed one before. It is determined whether or not the (n-1) th time log written in the (n-1) th recording device 50 is a type A time log. If it is determined that the (n-1) th time log is type A (S130: YES), the process proceeds to S140 and the (n-1) th representing the identification number of the (n-1) th recording device 50 from the (n-1) th time log. The identification number data and the (n-1) th elapsed time data indicating the elapsed time counted by the (n-1) th recording device 50 are extracted, and the process proceeds to S160.

  On the other hand, when it is determined in S130 that the (n-1) th time log is type B (S130: NO), the process proceeds to S150, and the latest type A among the time logs stored in the IC tag 2 is obtained. And the n-1th identification number data and the n-1 elapsed time data are calculated from the time log and the type B time log up to the (n-1) th time log thereafter. S160 Migrate to

  In S160, the elapsed time measured by the timer of the n-th recording device 50 is read, and n-th time difference data, which is the difference between the read n-th elapsed time data and the (n-1) -th elapsed time data, is calculated. In S170, it is determined whether the data length of the n-th time difference data is 11 bits or less, that is, whether the time difference is 2047 seconds or less. If the data length is 11 bits or less (S170: YES), S180 Migrate to

  In S180, nth identification difference data, which is a difference between the (n-1) th identification number data and the nth identification number data representing the identification number of the nth recording device 50, is calculated. It is determined whether the data length of the identification difference data is 4 bits or less, that is, whether the difference between the identification numbers is 7 or less. If the data length is 4 bits or less (S190: YES), the process proceeds to S200. A type B nth time log having a data length of 2 bytes is generated from the identification header (value 1), the nth identification difference data having a data length of 4 bits, and the nth time difference data having a data length of 11 bits. The process proceeds to S210.

  On the other hand, if it is determined in S120 that the past time log is not saved, that is, if it is the first check point (S120: NO), the data length is 11 bits or more, that is, the time difference is S170. If it is determined that it is longer than 2047 seconds (S170: NO), in S190, if it is determined that the data length is 4 bits or more, that is, the difference between the identification numbers is larger than 7 (S190: NO), the process proceeds to S220. A type A nth time log having a data length of 3 bytes is generated from the identification header (value 0), the nth identification number data having a data length of 6 bits, and the nth elapsed time data having a data length of 17 bits. The process proceeds to S210.

  In S210, the n-th time log generated in S200 or S220 is written in a free area following the already stored n-1 time log in the user area of the IC tag 2 detected in S100. The process ends.

Next, the procedure of the reception management process executed by the control unit 22 of the management apparatus 10 will be described with reference to FIG. FIG. 4 is a flowchart showing the reception management process executed by the control unit 22.
The reception management process is a process that is repeatedly executed by the control unit 22 while orienteering is held. When the process is started, the IC tag 2 is first detected by the R / W 12 in S300. It is determined whether or not. If the IC tag 2 is not detected (S300: NO), the process of S300 is repeated.

  On the other hand, when the IC tag 2 is detected (S300: YES), the process proceeds to S310, the ID of the IC tag 2 detected at the R / W 12 is read, the process proceeds to S320, and the ID read at S310. Is an ID stored in the memory 24. If it is determined that the ID is a stored ID (S320: YES), the process proceeds to S330, data consisting of a plurality of time logs stored in the user area of the IC tag 2 is read, and the process proceeds to S340.

  Then, in S340, a first time log having a data length of 24 bits is extracted from the beginning of the data read in S330, and in subsequent S350, the identification header (the first time log is a type A time log, the value is The 6 bits following (0) are decomposed as the first identification number data, and the subsequent 17 bits are decomposed as the first elapsed time data, and the process proceeds to S360.

  In S360, it is determined whether or not the identification header of the next time log is 0. If the identification header is 0, that is, the time log is a type A time log (S360: YES), the process proceeds to S370. In S370, the 23-bit data following the identification header is extracted. In S380, the data is decomposed into 6-bit identification number data and 17-bit elapsed time data, and the process proceeds to S390.

  On the other hand, if it is determined in S360 that the identification header is 1, that is, the type B time log (S360: NO), the process proceeds to S420, and 15-bit data following the identification header is extracted. Then, assuming that the 15-bit data is the n-th time log, in the subsequent S430, the first 4 bits of the 15-bit data are decomposed as the n-th identification difference data, and the subsequent 11 bits are decomposed as the n-th time difference data. The process proceeds to S440. In S440, the nth identification number and the nth elapsed time are calculated based on the n-1th identification number data and the n-1 elapsed time data, which are data obtained last time, and the process proceeds to S390.

  In S390, it is determined whether or not there is a next time log. If there is a next time log (S390: YES), the process proceeds to S360, and it is determined in S390 that there is no next time log. Until this is done, the processing from S360 is repeated.

  In S390, when it is determined that there is no next time log (S390: NO), the process proceeds to S400, the reference time set from the outside via the operation unit 26, and S350, S380, and S440. From the obtained elapsed time, the time at which the elapsed time actually measured by the timer of each recording device 50 is read is calculated, and in the subsequent S410, each recording device obtained in S350, S380, and S440 is calculated. The data is stored in the memory 24 together with the 50 identification number data, and the process is terminated.

  On the other hand, if it is determined in S320 that the ID is not stored in the memory 24 (S320: NO), the process proceeds to S450, the read ID is stored in the memory 24, and in S460, the ID is associated with the ID. The date and time at that time is stored in the memory 24, and the process ends.

  As described above, in the route management system of the present embodiment, the IC tag lent to the participant by the R / W 52 in the recording device 50 installed at each of a plurality of check points provided in the orienteering venue. 2 is detected, the control unit 54 reads the elapsed time from the reference time measured by the built-in timer, generates a time log from the elapsed time and the identification number of the recording device 50, and generates the generated time log. Is written to the IC tag 2 via the R / W 52.

  On the other hand, when the IC tag 2 lent to the participant by the R / W 12 is detected in the management device 10 installed at the reception of the orienteering hall, the control unit 22 of the management terminal 20 performs the IC via the R / W 12. The ID recorded in advance on the IC tag 2 and the plurality of time logs written by each recording device 50 are read from the tag 2 and stored in the memory 24.

  For this reason, according to the route management system of the present invention, the administrator who manages the orienteering venue reads the data written in the IC tag 2, so that the recording device 50 installed at the checkpoint through which the participant has passed. Since the identification number and the time when the check point passes can be grasped, it is possible to reliably manage the route that the participant has passed through the venue while at the reception.

  Then, the control unit 54 of the recording device 50 stores the previous time log in the IC tag 2 based on the elapsed time data representing the elapsed time measured by the timer and the past time log already written in the IC tag 2. Is generated when the time difference data representing the time from when the data is written and the data length of the generated time difference data is longer than 11 bits, that is, when the movement time between checkpoints is 2047 seconds (about 34 minutes) or more. Generates a type A time log in which an identification header indicating type A is added to elapsed time data and identification number data indicating an identification number. On the other hand, if the data length of the time difference data is shorter than 11 bits, the difference between the identification numbers is calculated from the identification number of the recording device 50 that wrote the previous time log in the IC tag 2 and the identification number of the recording device 50. If the data length of the identification difference data representing the identification number difference is longer than 4 bits, that is, if the identification number difference is greater than 7, it indicates that the type is A in the elapsed time data and the identification number data. A type A time log with an identification header added is generated, and if it is shorter than 4 bits, a 3-byte type A time log with an identification header indicating type B added to the time difference data and the identification difference data A 2-byte type B time log having a shorter data length is generated.

  For this reason, a type B time log with a data length of 2 bytes is generated for movement within the same zone, and a type A time log with a data length of 3 bytes is generated only for movement between zones. Therefore, more time logs can be written to the IC tag 2.

  In addition, an external device such as a personal computer can be connected to the recording apparatus 50 via the external I / F 56. When time is input from the connected external device, the control unit 54 receives the input. The time is set as an initial value for measuring the elapsed time from the reference time, and the elapsed time from the reference time is measured by a built-in timer based on the initial value. Therefore, when the administrator inputs the elapsed time from the reference time at that time, the control unit 54 sets the input value as an initial value, and measures the elapsed time from the reference time based on the initial value. Therefore, it is possible to set an initial value while sequentially turning each recording device 50, and to measure the elapsed time from the reference time, which is convenient.

  Then, in the management device 10, when the control unit 22 of the management terminal 20 actually reads the elapsed time in the recording device 50 based on a predetermined reference time and elapsed time data as a time log. Since the time is calculated and stored in the memory 24, it is convenient for the administrator to easily grasp information such as what checkpoint the participant has passed at what time and what time.

  In the embodiment described above, the time log corresponds to the time data of the present invention (the type A time log corresponds to the first time data and the type B time log corresponds to the second time data), and the control unit 22 and the control unit The timer provided in 54 corresponds to the time measuring means of the present invention, R / W 12 corresponds to the reading means of the present invention, and R / W 52 corresponds to the writing means of the present invention.

  And the process of S100 is equivalent to the 1st detection means of this invention, the process of S110-S200, S220 is equivalent to the data generation means of this invention, the process of S210 is equivalent to the 1st control means of this invention, The process of S300 corresponds to the second detection means of the present invention, and the processes of S330 to S440 correspond to the second control means of the present invention.

As mentioned above, although one Embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form.
For example, in the present embodiment, when both the identification number of the recording device 50 and the identification difference data and the time difference data representing the difference in elapsed time measured by the recording device 50 are equal to or less than a predetermined data length, The type B time log is generated, but only the elapsed time written by the recording device 50 is taken according to the arrangement of each checkpoint, and the identification header, the identification number, and the elapsed time A time log may be generated from the difference.

  In the present embodiment, the specified data length of the identification difference data is 4 bits, and the default data length of the time difference data is 11 bits. However, this also depends on the arrangement of each checkpoint and the like. Type B time log with 3 bits that can be recorded with an identification number difference between -3 and 3 and 12 bits that can record between 0 and 4095 seconds (about 68 minutes) as the default data length of time difference data You may comprise so that it may become 2 bytes as a whole.

  In addition, each type of time log is composed of 3 bytes and 2 bytes in order to enable writing in byte units. However, when writing in bit units is possible, the data length of each time log is not in byte units. May be.

  In the present embodiment, the recording device 50 measures the elapsed time from the reference time by using a timer, and writes the elapsed time to the IC tag 2 when the IC tag 2 is recognized. A clock function for measuring a specific time may be provided, and the time when the IC tag 2 is recognized may be written.

  Further, in the present embodiment, the current time is measured in seconds and written in the IC tag 2, but may be measured in minutes. In this way, it is possible to set the data length of the time log to be short or to write data for a longer time with the same data length, so that it can be used for a wider range of applications.

  The present embodiment is an example in which the route management system of the present invention is used to manage a participant's movement route at an orienteering venue, but may be applied to various other venues, facilities, and the like. For example, it can be used only for a limited number of people, such as companies and research institutes. It may be used to manage the travel route within the facility.

  When applying to such a facility, the IC tag 2 is built in the temporary permit, and R / W is installed at the entrance / exit of each area in the facility, and when an outsider enters each area, The permit may be held over the R / W and a time log may be recorded on the IC tag 2 held over. In this way, when the temporary permit is returned, the travel route within the facility of the outsider can be managed by reading the time log. In addition, if each area is locked and this permit has a function as a key to unlock the locked area, the permit will be surely entered when entering the area. Since it is held over the R / W, it is possible to more reliably manage the movement route.
