DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for confirming the presence or absence of a call target using radio waves.
The present invention relates to a roll call system that allows a user to make a roll call promptly without sight or voice when traveling in a group.

[0002]

2. Description of the Related Art Conventionally, leaders of school excursions and group tours confirm whether all participants are present at each meeting place by calling each person's name or visually confirming each participant. And rolled calls by counting the total number of people.

[0003]

The conventional roll call method has the following problems.

[0004] In the method of taking attendance by calling each person's name, there is a problem in that it takes time to take out a roll call or it is necessary to make a voice, which inconveniences people around. In addition, there is a problem that it is difficult to take a roll call in a place where noise is severe.

[0005] In one person confirmation How participants visually, in addition to that that takes time to take a roll call, a problem that easily mistaken for or moving the roll-call person (human side to be taken the roll call) there were.

[0006] The method of counting the total number of people has a problem that, when there is an absentee, it is possible to know how many people are, but not to know who is absent.

In order to recognize the presence of a specific person, a system for detecting a mountain climber who has been a victim using a portable transmitting / receiving device and a calling transmitting / receiving device as disclosed in Japanese Patent Application Laid-Open No. 63-198424 has been proposed. Although proposed, this is a one-to-one relationship between the calling party and the called party, and cannot be used as a roll-call system.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a roll call system capable of making a roll call quickly.

Another object of the present invention is to provide a roll call system capable of confirming who is absent as a result of the roll call.

Still another object of the present invention is to provide a roll call system capable of quickly creating a roll list for a roll call.

[0011]

In order to achieve the above object, a system using a handy terminal storing a list of persons to be rolled and a contactless IC card for wirelessly transmitting and receiving information to and from the terminal. Is used. First, the handy terminal communicates with a specific contactless IC card associated with the callee using wireless communication. Specifically, a call signal is transmitted, and it is determined whether or not the called party is at the location based on whether or not there is a response to the call signal. If the radio used at this time reaches only a range (for example, about 20 m) that is determined to be at the place when the roll call is captured, it is determined that there is no response if there is no response. Can be. In this way, the handy terminal calls all contactless IC cards of the target person described in the list. Next, a roll call result is created by determining the presence or absence of the target person in the list, and the roll call result is displayed on the handy terminal. The display contents include the total number of the rolled call targets, the number of absentees, and the name of the absentee. In addition, by displaying an icon on the handy terminal for inputting the presence / absence information corresponding to the displayed name of the absentee, the caller confirms the call by visual or voice, etc. Enter the result.
With this configuration, the roll caller can take a roll call without making a voice each time, and can instantly know who is absent.

[0012]

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

FIG. 1 is a diagram showing the concept of the overall system of the present invention. The callee 1 who is the person who is to be rolled,
Each has an IC card 2 that can be read without contact. A caller (not shown) has a handy terminal 4,
The handy terminal 4 sequentially communicates with the IC card 2 owned by the callee using the radio wave 3 to determine whether the callee is at that location. The communicable distance of the IC card 2 that can be read in a non-contact manner can be set arbitrarily according to the output and the frequency to be used. It is sufficient that the necessary transmission distance can be sufficiently communicated when the tens of people gather. For example, in the case of a guide of 50 people, it is sufficient to be able to communicate over a distance of about 20 m. It should be noted that if the transmission distance is too long, it may be regarded as being gathered when it is not gathered at the place.
The handy terminal 4 is large enough to be easily carried by a roll caller and has display means such as a liquid crystal display for displaying information and input means such as a pen input method.

FIG. 2 is a block diagram showing the configuration of the IC card 2 owned by the callee 1. The IC card 2 is, for example, a card having a thickness of 0.76 mm and the same size as a credit card. The receiving coil 5 functions as an antenna for transmitting / receiving the handy terminal 4 by radio waves. This coil can be formed on a substrate of a card such as plastic using a printing technique. The transmitting / receiving unit 6 controls wireless transmission / reception performed via the coil 5 and converts radio waves and electric signals. The transmission / reception unit 6 can be realized by using a known radio technology, but includes a tone squelch or a digital squelch for performing only communication with a specific partner, or a function equivalent thereto.
With this configuration, the other handy terminal 4
Interference can be prevented even if there is a call from The memory 8 is a storage unit for storing information, and can be configured by a semiconductor memory. The storage capacity may be set as needed. As in the present embodiment, if a roll call is merely taken, a small capacity is not necessary. However, by increasing this capacity, various application programs can be stored and executed. An MPU (Micro Processor Unit) 7 stores information received via the transmission / reception unit 6 in the memory 8,
Control for transmitting information in the memory 8 via the transmission / reception unit 6 is performed. In addition, since the MPU 7 has an arithmetic function, it is possible to perform processing using a program such as encryption processing. The power of the IC card 2 may be supplied from a battery (not shown) incorporated in the card, or may be supplied from outside via the receiving coil 5.

FIG. 3 is a table showing the contents of data stored in the memory 8. In the present embodiment, information for taking a roll call of the callee is stored. The radio wave identification information 31 stores the radio wave frequency and tone frequency when the IC card 2 responds. This example indicates that a response should be made when called with a signal in which a 66.4 Hz audio tone is superimposed on a 422 MHZ radio wave. If the types of the radio wave and the voice tone are set differently for each IC card owned by the callee 1, the influence of the interference can be prevented. The identification number 32 is a unique identification number for each of the callees 1. For example, if the callee 1 is an elementary school student, the first four digits should be the elementary school identification code, the next one should be the school year, the next two digits should be the class, and the last two digits should be the attendance number. Can be. The figure shows that the child is an elementary school 6th grade 1st class attendance number 12 with an identification code 0102. Name 33
Is the name of the callee, and is actually Shift-JI
It is coded with an S code and stored. History information 3
Reference numeral 4 denotes a communication status with the handy terminal 4. In this example, the communication time, the identification number of the handy terminal 4, and the communication (UP) at the time of creating a list, which will be described later, or the communication at the time of a roll call (CHECK) are stored.

FIG. 4 is a block diagram showing the configuration of the handy terminal 4. As shown in FIG. The transmission / reception unit 41 wirelessly transmits / receives to / from the IC card 2 and includes an antenna unit (not shown). The overall control unit 42 is an MPU (Micro Processor Uni
Various controls are performed by the program including t). The display unit 43 visually displays information such as liquid crystal display means. The input unit 44 is used by an operator to input information, and may use input means such as a keyboard, a touch pen type input device, and a touch panel type. The memory unit 45 includes a volatile semiconductor memory used for the operation of the overall control unit 42 and a nonvolatile storage device such as a magnetic disk, a floppy disk, and a card memory. The memory unit 45 also stores a program for operating the overall control unit 42. FIG.
The handy terminal 4 described in, for example, has a small pen-input type liquid crystal display unit and a small antenna as shown in FIG. 1 so that the operator can easily hold it. The handy terminal 4 can have not only the dedicated terminal as the roll call system but also other general functions as a small portable terminal, a schedule management function, a calculation function, and a database function. In other words, the system of the present invention can be realized by providing the transmitting / receiving unit 41 in a commercially available small portable terminal and introducing a program for implementing the present invention.

Next, the operation of the roll call system according to the embodiment of the present invention will be described with reference to the flowcharts of FIGS.
FIG. 5 shows a procedure for registering a list necessary for taking a roll call in the roll call system. In general, there is a pre-determined roster for school trips for elementary school students and the like, so there is no need for the procedure in this figure. However, FIG. 5 shows a method for easily creating a roster when there is no roster. .
FIG. 6 is a flowchart showing the operation of the IC card 2 when responding.

The procedure shown in FIG. 5 is executed by the handy terminal 4 of the person taking the roll call. First, the handy terminal 4 sets initial values of a communication frequency and a tone frequency with the IC card 2 (step 51). Since the frequency and tone signal used for the IC card 2 have a predetermined band, the lower limit of this band may be set. Next, a call is made to the IC card (step 5).
2). If there is an IC card 2 owner that matches the combination of the set frequency and tone frequency, the IC card 2
There is a response from

Here, the operation of the IC card 2 will be described with reference to the flowchart of FIG. The IC card 2 is usually in a standby state of waiting for a wireless call (step 61). Next, it is determined whether or not there is a call from a certain handy terminal 4 (step 62). It is determined whether or not this call has occurred when there is a call at the same frequency as the frequency set in the IC card, and when the frequency of the tone signal matches, it is determined that there has been a call. If there is no call at the same frequency, or if the tone frequencies do not match, the process returns to step 61.

If there is a call, it is determined whether the call is for a list creation or a roll call (step 63). This determination can be made easily by including such an identification signal in the signal transmitted from the handy terminal 4. In the case of the list creation mode, the identification number 32 and the name 33 stored in the IC card 2 are returned (step 64). In the simple roll call mode (described later), a response indicating presence, for example, a signal indicating reception has been returned (step 65). Next, the IC card 2 records this response status in the history information 34 and returns to step 61 (step 66).

Returning to FIG. 5, it is determined whether or not there is a response from the IC card 2 (step 53). If there is a response, a list is created based on the content of the response (step 54). If there is no response, skip step 54 and change the frequency and tone frequency (step 5
5). As described above, when the search to the predetermined upper limit of the band is completed, the search for the non-caller ends, and the list created up to that time is registered. In this manner, the name list can be easily created. At this time, the name list is displayed on the display unit 43 of the handy terminal 4 so that the caller can actually visually check the name list, or can input a new callee from the input unit 44. You may input it.

FIG. 7 shows the contents of the created list, which is stored in the memory unit 45 of the handy terminal 4. The identification number 71 and the name 72 indicate the IC that responded.
The identification number 32 and the name 33 obtained from the card 2 are stored. The ringing frequency 73 and the tone 74 store sets of frequencies and tones used when a response is made. The roll call 75 is an area for storing a flag indicating whether or not there is a response when a roll call is made after the list is created, and is used when actually performing the roll call.

Next, the operation for making a roll call will be described with reference to the flowchart of FIG. The operation of this flowchart is also executed by the handy terminal 4.

First, the data (frequency 73, tone 74) of the person at the head of the list shown in FIG. 7 is read (step 8).
1), the transmission / reception unit 41 uses the person's frequency 73 and tone 74
To call the IC card (step 82). The called IC card 2 responds by the operation shown in the flowchart of FIG. 6 (step 65 in FIG. 6). The handy terminal 4 determines whether or not there is a response. If there is a response, the handy terminal 4 sets a flag (for example, “1”) indicating that there is a response in the presence column 75 of the list of FIG. If there is no response, a flag (for example, '0') indicating that there is no response is set in the presence column 75 (step 85). Next, it is determined whether or not the last person in the list has been called, and if not, the data of the next person in the list is read and the process returns to step 82 (steps 86 and 87). Step 8
If the processing is completed up to the last person in the list, the total number of persons, the number of confirmations, and the number of unanswered persons are calculated by totaling the roll call column 75 of the list in FIG. 6, and a list of unanswered persons is displayed. (Step 88). FIG. 9 shows an example of the displayed screen. The handy terminal 4 has a date and time 91 at which the call was made, a total number 92 of persons to be called, a number 93 of respondents,
The number of absentees (non-responders) 94 and the absentee name 95 are displayed. Icons 96 and 97 for inputting the confirmation result by visual observation are displayed in the vicinity of the absentee name, for example, on the right side in correspondence with the name.

Next, the presence or absence of each of the displayed absentee names 95 is visually checked, and if there is, the icon 96 indicating the presence is selected with a pen. Icon 96 to be displayed (step 8)
9). When an icon 96 indicating the presence of this icon is input, a flag (for example, '01') indicating that there is no response but actually exists is stored in the presence column 75 of the list of FIG. 7, and the roll call processing ends. Note that the memo column 98 in FIG. 9 is an area for freely entering a place when a roll call is taken, the reason for the absence of the absentee, and other comments. The memo entered here is stored in the flag of the above-mentioned existence column 75. Correspondingly, it is stored in the memory unit 45.

The present invention can be variously modified.
For example, in FIG. 9, an icon for instructing deletion from the list is displayed in addition to the icons 96 and 97, and when this is selected, FIG.
May be deleted from the list. By doing so, it is possible to exclude a person who performs another action from the middle of the group trip from a roll call target.

Further, in order to include a person who joins in the middle of a group trip, the roll list processing is re-executed when the roll call processing is performed, and the list is updated by adding a person who is not registered in the list. be able to.

Further, the roll call system of the present invention can be applied to various fields. For example, by using the processing of FIGS. 5 and 6, it is possible to create a participant list of persons who have participated in various events, and to apply the present invention to a reception system at a window such as a hospital. In addition, each person has a handy terminal 4
With this, instead of exchanging business cards, information on participants can be obtained by using the list creation function of the present invention. In this case, instead of the present of the roll-call person 1 is information sent from the identification number 32 and name 33, it may be transmitted information to be written on a business card.

[0029]

As described above, according to the present invention, it is possible to automatically create a list of gathered persons by using a contactless IC card, so that the efficiency of list creation is improved. In addition, when a roll call is made based on the list, a roll call can be made, and the roll call can be made easily and securely without visually making the roll call. Furthermore, even if any communication error that cannot be avoided when using radio waves occurs, only the person can be visually confirmed and the information can be easily input.
