[0002]

2. Description of the Related Art Conventionally, in group travel, before and after using transportation, or at tourist sites such as historic sites,
It is customary that the tour operator or tour manager rolls the number of participants, confirms and confirms that all of them are gathered by this rolling work, and then moves on to the next action.

[0003]

By the way, when the number of people is confirmed by roll call as in the prior art, if the number of people counted does not reach the specified number, the number of people is counted again. Must identify who is absent. In this case, if the number of participants is small, re-checking the number of people and confirming the absentee does not require much labor, but if the number of people is large or there are many check points,
There has been a problem that a lot of labor and time are required, which eventually leads to a delay in departure time and a shortened tour time. The present invention has been proposed in view of such conventional circumstances. Therefore, a technical problem of the present invention is to provide a personnel confirmation device formed so that a large number of persons can be confirmed instantaneously and an absentee can be specified.

The frequency division value N of the frequency division ratio 1 / N of the frequency division unit 103 is variable by the frequency division value variable unit 124. That is,
The frequency division value changing unit 124 uses the slave units 11c to 20c described above.
The frequency division ratio 1 / N of the frequency division unit 103 can be varied by sequentially outputting the variable frequency division values N of "1" to "10" of the frequency division value N. In accordance with this variable operation, the frequency of the reception frequency signal 125 is converted into the frequency of the radio wave signal 114 of each of the slaves 11c to 20c, and the reception frequency generator 1 is generated.
It is sequentially output from 23 to the receiving unit 117.

The receiver 117 receives the received frequency signal 12
The received signal 126 received in accordance with No. 5 is output to the conversion unit 118. The conversion unit 118 outputs the data value 127 corresponding to the frequency of the received signal 126 to the matching unit 119. The storage unit 120 stores the radio frequency signals 10 of the slaves 11c to 20c.
The data value 128 corresponding to the frequency of 9 is stored. The matching unit 119 also takes in the data values 127 sequentially output from the conversion unit 118 one by one, and takes in the taken data values 127 and all the data values 1 stored in the storage unit 120.
By collating 28, the data value 128 that matches the data value 127 is detected. This operation is performed on the data values 127 of all the slaves 11c to 20c, and the stored data value 1 which is not detected by this detection operation.
28 is output to the display control unit 121 as an undetected number 129. The display control unit 121 controls to display the undetected number 129 on the display unit 122.

Next, the operation of the device of the present invention in such an embodiment will be described. However, as shown in FIG.
3c, the 5th cordless handset 15c, and the 8th cordless handset 18c shall be separated from the electric wave receiving range of base unit 21. Each cordless handset 11c
The radio signals 114 having different frequencies are transmitted from the mobile stations 20 to 20c to the master device 21c. This is each cordless handset 11c to 20c
This is because the frequency division unit 103 divides the radio frequency signal 109 by the frequency division ratio 1 / N which is different for each.

On the other hand, in the master unit 21c, each slave unit 11
c, 12c, 14c, 16c, 17c, 19c, 20c
The radio signal 114 transmitted from is received sequentially according to the frequency variable control of the reception frequency generation unit 123. The received signal 126 is converted by the conversion unit 118 into a data value 127 corresponding to the frequency of the received signal 126, and the converted data value 127 is collated with the stored data value 128 of the storage unit 120 by the collation unit 119. That is, the collating unit 119 detects all the stored data values 128 that match the data value 127, and the undetected stored data values 128 are output to the display control unit 121 as undetected numbers 129.
It is displayed on the display unit 122 under the control of the display control unit 121. In the embodiment described above, the same effect as that described in the first embodiment can be obtained.

In the device of the present invention, the storage means, the encoding means, which constitute the slave unit and the master unit of each of the above-mentioned embodiments,
The decoding means and the like are composed of commercially available ICs,
Further, the slave unit and the master unit may be combined with other constituent elements. It is preferable that the batteries of the child device and the parent device are as small as possible and have a long life. Examples of such a battery include a button-type silver oxide battery, a button-type alkaline battery, a lithium-ion battery, and a nickel-cadmium battery (secondary battery). Further, in the case of the present invention, since the child device is to be carried and used by a person, it is preferable to be formed into a clip type, a pendant type, a ring type, a bracelet type or the like. In this case, since it can be worn on the body and not in the way, it becomes easy to carry and the usability is improved.

In addition to the above, the device of the present invention can also be applied as, for example, a bus passenger confirmation system, a dementia geriatric loitering prevention system, and a bicycle confirmation system described below. That is, the bus passenger confirmation system confirms the number of passengers on a sightseeing bus or the like with one touch. The demented old man loitering prevention system, the demented old man with wandering habit has the slave unit of the present embodiment, and when a certain distance is left, the alarm device of the slave unit is sounded so that the person can confirm it. It makes it possible to prevent mistakes.

In addition, bicycles are parked by themselves at bicycle parking lots at large stations or parking lots at supermarkets, but there are guards at such places, and bicycles are often rearranged neatly. In such a case, I try to search for the bicycle at the first position, but it takes a considerable amount of time to search because the position has changed. Therefore, if the slave unit of the device of the present invention is attached to the bicycle, the slave unit will ring when the master unit calls it, and the bicycle can be easily found at a distance where the sound can be heard. Further, when the slave unit is provided with a light emitting source such as a light emitting diode which emits light upon receiving a transmission signal from the master unit, the discovery becomes easier.

[0046]

As described above, in the case of the present invention,
Since the master unit displays the ID number of the slave unit that cannot receive the radio wave, the confirmer can instantly confirm and specify the person carrying the slave unit with the displayed ID number. Further, in the case of including the master unit of the type that collects the ID number of the slave unit by the trigger signal, the circuit that is normally off can be operated only when the trigger signal is transmitted, so that it is possible to suppress the power consumption. There is. Further, in the case where the mobile phone of the type that sounds by the trigger signal is provided, there is an advantage that the mobile phone of the mobile device can recognize that a call is being made by the sound.
