The trunked system shown in FIG. 6 includes a control station 5, a repeater system 2, and a wireless communication terminal (not shown). For example, a plurality of mobile bodies (mobiles) 6 divided into groups 1 to 3 It consists of From the control station 5, it is possible to perform a simultaneous call to all mobile bodies 6 equipped with wireless communication terminals, a call to each group of mobile bodies 6, and a call to individual mobile bodies 6. Moreover, communication between mobile bodies is also possible.

  FIG. 1 shows a wireless communication terminal 1 of the present invention configured to be used in the trunked system described above.

  In FIG. 1, reference numeral 11 denotes a power switch of the wireless communication terminal 1. A PTT (Push to Talk) switch 12 is mounted on the side (side surface) of the wireless communication terminal 1 so as to be easily operated. The wireless communication terminal 1 is set to the transmission mode only during the period during which the PTT switch 12 continues to be pressed, and when the pressing operation is released, the wireless communication terminal 1 is set to the reception mode. As described above, the wireless communication terminal 1 is configured to perform communication by arbitrarily setting the transmission / reception mode by the pressing operation or the pressing release operation of the PTT switch 12.

  Reference numeral 13 denotes a fingerprint reading unit provided integrally with the PTT switch 12, which is a means for reading the fingerprint of the terminal user. The fingerprint reading unit 13 includes a finger sensor (not shown) having a sensor surface on which a finger can be placed, and is provided at a position where the terminal user's finger is placed on the PTT switch 12.

  A storage unit 14 includes a fingerprint registration unit 141 that can register fingerprints of a plurality of terminal users. A fingerprint authentication unit 15 is a means for collating the read fingerprint data read by the fingerprint reading unit 13 with the registered fingerprint data of a plurality of terminal users registered in advance in the storage unit 14. Reference numeral 16 denotes a control unit that operates the wireless communication terminal 1 based on the collation result of the fingerprint authentication unit 15.

Reference numeral 22 denotes a transmission / reception antenna.

  The operation of the wireless communication terminal 1 of the present invention configured as described above is stored in the flowchart showing the operation of turning on the power shown in FIG. 2, the flowchart of the voice transmission process shown in FIG. 3, and the fingerprint registration unit 141 shown in FIG. A description will be given based on an example of a fingerprint database.

  The flowchart of FIG. 2 shows each step in which the wireless communication terminal 1 can be turned on on condition that fingerprint data is registered in the fingerprint registration unit 141 as a terminal user of the wireless communication terminal 1 in advance. . Therefore, fingerprint data of all terminal users and ID number information set for each terminal user, such as transmission / reception frequency and usage ID number, are stored in the fingerprint registration unit 141 in advance as a fingerprint database.

  In the fingerprint database shown in FIG. 4, fingerprint information of a specific terminal user, name, group number ID, ID, transmission frequency, and reception frequency are stored in association with each other.

  First, the power switch 11 is turned on (powered on) while pressing the PTT switch 12 (step S1). When the power switch 11 is turned on while pressing the PTT switch 12 in step S1, the fingerprint reading unit 13 reads fingerprint data (step S2).

  When the fingerprint data is read, the fingerprint authentication unit 15 calls a plurality of terminal user fingerprint databases stored in the fingerprint registration unit 141 and registered in advance (step S3), and converts the fingerprint data read into the fingerprint database. It is verified whether there is a matching fingerprint (step S4).

  If the registered terminal user is confirmed in the next step S5 based on the collation result of the fingerprint authentication unit 15, the process proceeds to the next step S6 and the power-on state of the wireless communication terminal 1 is maintained. The ID number information such as the transmission / reception frequency and the use ID number set for each terminal user stored in the fingerprint registration unit 141 is read as the function setting of the wireless communication terminal 1. After saving in the storage unit 14, the state shifts to a standby state.

  On the other hand, when it is not confirmed that the terminal user is registered, the power of the wireless communication terminal 1 is turned off and the process is terminated. As a result, the wireless communication terminal 1 cannot be used, and unauthorized use of the wireless communication terminal 1 can be prevented.

  In addition to the security operation described above, the present embodiment is further configured to prevent unauthorized use even if the wireless communication terminal 1 is stolen when the power switch 11 is on. ing. This operation is shown in the flowchart of the voice transmission process in FIG.

  The operation will be described based on the flowchart of the voice transmission process of FIG. First, when the PTT switch 12 is pressed to perform voice transmission (step S11), the fingerprint reading unit 13 reads the fingerprint of the terminal user who pressed the PTT switch 12 (step S12).

  When the fingerprint of the terminal user is read, the fingerprint authentication unit 15 calls up the fingerprint data of the terminal user acquired when the power switch 11 is turned on while pressing the PTT switch 12 from the storage unit 14 ( Step S13). In the next step S14, the fingerprint of the terminal user who is currently pressing the PTT switch 12 matches the fingerprint of the terminal user acquired when the power switch 11 is turned on while pressing the PTT switch 12. It is checked whether or not to perform (step S15).

  As a result of the collation, if it is confirmed that the user is a terminal user, the process proceeds to the next step S16. In this step S16, the registered ID number stored in the storage unit 14 is called, and in the next step S17, a tone signal including the called registered ID number information is added to the carrier wave and voice transmission is executed. Note that the tone signal used in the trunked system is composed of 40 bits, of which 8 bits are assigned to the ID number information of the terminal user.

  On the other hand, in step S15, as a result of the collation, the fingerprints do not match, and the terminal user who is now pressing the PTT switch 12 and wants to perform voice transmission turns on the power switch 11 while pressing the PTT switch 12. If it is determined that it is different from the terminal user at the time, the voice transmission is not performed, and the process ends. As a result, the terminal user who is now pressing the PTT switch 12 cannot perform voice transmission, and can prevent unauthorized use of the wireless communication terminal 1.

  According to the present embodiment configured as described above, in a wireless communication terminal provided with a PTT switch, a fingerprint reading unit provided in the PTT switch, a terminal using a plurality of terminal users' fingerprint data and the fingerprint data registered therein A storage unit that can register ID number information including at least a use ID number set for each person, a fingerprint authentication unit that collates fingerprint data read by the fingerprint reading unit with registered fingerprint data in the storage unit, and a fingerprint authentication unit And a means for operating the wireless communication terminal based on the collation result and a means for obtaining one ID number information from the storage unit based on the collation result of the fingerprint authentication unit. It has an advanced security function that can be used only by a specific plurality of terminal users.

  Also, even if the wireless communication terminal to be used is changed, the ID number information can be acquired based on the fingerprint collation result and automatically changed to the terminal user individual setting. The troublesomeness of setting ID number information can be eliminated. Furthermore, there is no mistake in the radio communication terminals, and there is no terminal user having the same use ID number in the group, so that so-called impersonation can be prevented.

  Further, in the above-described embodiment, when it is determined that the terminal user who is going to perform the voice transmission process is different from the terminal user when the power switch 11 is turned on while pressing the PTT switch 12, The processing is terminated without performing transmission, but the power switch 11 may be turned off. In this case, a more advanced security function can be realized.

  In addition, when it is determined that the terminal user who is going to perform voice processing is different from the terminal user when the power switch 11 is turned on while pressing the PTT switch 12, the stored other terminal is used. The personal data of the collated terminal user may be read if they match with the fingerprint data of the user. In this case, since the ID number information is changed when voice transmission processing is performed even when the terminal user is changed after the power is turned on, so-called impersonation can be prevented more reliably.
