Abstract

PURPOSE:To provide additionally a pass word function to a radio equipment by inputting a group number of an opposite device by a key, storing the number in a group number memory in a CPU, reading the number from this memory at talking, transmitting the group signal to the radio equipment and also bringing the radio equipment into the transmission mode. CONSTITUTION:The user inputs the group number (call number) of the opposite party from a key input device 3 and displays the inputted group number to a group number display device 1 via a CPU 6. Further, the inputted group number is stored in an RAM 7 in the CPU 6. Then the group number of the opposite device is read from the group number memory RAM 7 in talking. The read group number of the opposite device is transmitted to the radio equipment 13 via an MODEM 12 from the CPU 6. Further, the CPU 6 transmits the group number to the radio equipment 13 and also the radio equipment 13 is brought into the transmission mode and a control signal is outputted from the radio equipment 13 via an antenna 16.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wireless device such as a personal wireless device that performs communication by setting a group number.

Conventional configuration and its problems Conventional wireless devices that perform communication by setting a calling number of the other party do not have a function to prohibit unauthorized use by others.

Purpose of the Invention The present invention eliminates the problems of the above-mentioned conventional example,
The purpose is to prevent unauthorized use by others without adding a memory for passwords.

Structure of the Invention In order to achieve the above object, the present invention utilizes a group number memory to add a password function.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 schematically shows a personal radio device which is an embodiment of the present invention. In FIG. 1, 1 is a group number display, and this group number display 1 displays a five-digit group number inputted from a key input device 3. Reference numeral 2 denotes a device status indicator 2 for displaying the status of the personal radio. For example, this device status indicator 2 displays [READYJ] when the device is in a standby state, and displays l'-TALK'J when the device is in a talking state. 4
is a display interface, and this display interface (−
The face 4 controls the group number display 1 and the equipment status display 2 based on the display take output from the central processing unit (CPU) 6. 5 is a key human power interface, and this key human power interface 5 is a key human power device:
The key manual data input from 3 is transmitted to 0PU6. 7 is a random access memory (R,
AM), 8 is a read-only memory (R, OM) that stores a program for controlling the CPU 6. Reference numeral 9 is for connecting the input and output ports. 10 is a timer within the input/output interface 9;
performs time management for the CPU 6. ] 1 is an IDROM in which the license number is stored, 14 is a phase locked loop (PLL) provided in the radio 13, J5 is a microphone for inputting audio, 16 is an antenna, and 17 is a speaker for outputting audio signals. .

The above CPU6 is the license number stored in IDROMII,
Read group number stored in RAM, 7, specify wireless channel, send/receive control signals (synchronization signal, group number, call channel number, license number), microphone]
It has functions such as operation when the breath talk switch provided at 5 is pressed, control of the display, connection and control of telephone calls, etc.

The personal radio shown in Fig. 1 is a simple radio station that uses radio waves in the 900 MHz band, and has a frequency of 251 (J
-80 channels are assigned to each Iz (channel 1 is a control channel, channels 2 to 80 are communication channels). The user inputs the group number (calling number) of the other party using the keypad 3, and inputs the input group number to C! P.U.
6 on the group number display 1. The input group number is still held in the RAM 7 within the CPU 6. FIG. 2 shows the key manual device 3, and when storing the group number in R, AM7, rOJ r*J r
Press OJ, then rlJ r2J r3J r4J
By pressing r5J, r
The group number "12345J" is stored in the OJth position.Other group numbers can be stored in the "1" to "9th" positions of the group number memory by a similar operation. Here, the group number stored in the 0th position of the group number memory becomes the center lock keyword, and in the password judgment routine described later, unless the same number as the center lock keyword [1,234,5J is entered, the person will be locked. The radio does not work.

When making a call, the group number of the other party is read out from the group number memory. The group number of the other party that has been read out is sent from the CPU 6 to the wireless device 3 via the modem 12. At the same time, the CPU 6 sends the group number to the radio device 13, sets the radio device 13 to the transmission mode, and a control signal is output from the radio device 13 via the antenna 16.

In this way, by transmitting to the other station the group number that the other station is waiting for, it becomes possible to make a call and make a conversation.

When calling the other party in this way, it is first necessary to set the other party's group number on the personal radio, and the frequently used group number is set in advance to C! RAM7 inside PU6
is memorized.

The RAM 7 also stores a group number (receiving number) for receiving a call from the other party. The group number is made up of random five-digit numbers. In this embodiment, the CPU
A password function is added by utilizing the group number memory included in the internal RAM 7 of the 6.

The operation of this embodiment will be explained below. The following explanation assumes that during the previous call, you set the Siseno lock by operating ``6 Power is supplied to the circuits inside the machine, and the C!PU 6 starts operating.The CPU 6 executes the program stored in the ROM 8 and sets a starting value in the circuit.

After that, a password determination routine is executed.

At the beginning of the password determination routine, a display is made on the group number display 1 to inform that the next password is to be input. FIG. 4 shows an example of a display indicating that a password is being input. R in to the 5-digit group number display l
Put J (a) is first shown for 1 second.

Next, "y o u r J (b)" is displayed for 1 second, and finally "co r d J (c)" is displayed for 1 second, and then the password input is waited.This is the same as the password shown in Figure 3. This is done in step A of the format routine.Next, the address of the group number (set lock keyword) to be compared with the first character of the password input in step B is sent to the CPU 6.
is set in the internal RAM 7 of the address, and the match or mismatch between the data indicated by this address and the one-character password data input in step C is performed in step D. In step D, if the input one-character data does not match the password, the process returns to step B and returns to the first address of the comparison group number. If it matches the /ζJ character character password entered in step D, step 1
In step F, the address of the comparison group number is moved to the address above the next sentence', and it is determined in step F whether that address is the password end address. If it is determined that the address is not completed, the process returns to step C and the password is input again. This process is repeated until the comparison group number address is completed.

In this manner, after the user turns on the power of the personal radio, the personal radio will not operate unless the user inputs a preset arbitrary group number as a password from the key-powered device 3.

FIG. 5 shows the basic configuration of the device of the present invention.

In FIG. 5, 18 is a key manual means, and 19 is an address for specifying the address of the group number (seven-no-doronk keyword) stored in the 0th position of the group number memory 20, and reading out the characters of the group number sequentially from the beginning. A designation means 21 compares character data of the read group number with character data input from the key manual means 18 character by character and determines whether they match or not; 22 a comparison means which operates the radio based on the comparison result; It is a control means for controlling.

Effects of the Invention The present invention has the above-mentioned configuration, and has the advantage that a read function can be added according to the present invention.

Therefore, unauthorized use of the radio by another person can be prevented.
