Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides for
This invention relates to a device that can be called individually or in groups by sending and receiving identification codes.

[Prior Art] Among wireless transceivers, a personal radio device is generally known as a simple radio equipment that uses the 900 MHz band. These so-called personal radios have a five-digit identification number called a group number, and only radios whose transmitted and received identification numbers match can communicate with each other. Considering the function of this group number, when making a call, it can be separated into a group number for making a call and a group number for receiving a call.

Traditionally, this way of calling and being called is,
There were two methods described below.

One method is for personal radios that cannot be set independently because the calling group number and the incoming group number setting device are common, and are called individually. In this case, first set as follows.

Win “ABCDO”, 111 “ABCDl” Handset 2 “ABCD2”, Handset 3 “ABCD3” Therefore, when calling Handset 1 from the base unit, set the group number of the base unit to “AB”.
C[)1” and make a call.

If you do not return the least significant digit to "O" when the call ends, you will not be able to respond to subsequent calls from the handset.

Also, when calling the base unit from the slave unit, enter the group number of the slave unit “
ABCDO". If you do not change the number back to the original number when you end the call, you will not be able to answer subsequent calls.

Another method is to have a device that can separately set the calling group number and the standby group number.

In this case, first set as follows. Base unit calling “AB”
COX"・Hold ABCDO", child m'+ call"
A B CD
2's call "ABCDX"/Holder's receiver ABCD2", handset 3's call "ABCDX", hander's receiver "ABCD3", and when calling from the base unit to the handset or from the handset to the base unit, Set the last digit of the other party's group number to "O to 3" and make a call.

[Problems to be Solved by the Invention] As described above, even with the conventional method, it is possible to create a reason for individual calling as described above.

However, in the former method of sharing a group number for sending and receiving, after the call ends, the calling party needs to return the setting to the original group number in preparation for subsequent calls.
The latter conventional method of separately setting group numbers for transmission and reception requires a function to set a plurality of group numbers, which has the disadvantage of increasing costs and making operations complicated.

Furthermore, when considering the addition of a simultaneous call function, it becomes necessary to separately set a group number for receiving, making the configuration complicated.

Therefore, this invention was made to solve the above-mentioned problems in the prior art, and its purpose is to enable individual calls or simultaneous calls between a plurality of wireless communication devices. The object of the present invention is to provide a wireless transceiver that can be easily operated and configured at low cost.

[Means for Solving the Problems] The gist of the present invention to achieve the above object is to have two types of setting changeable identification codes consisting of multiple digits, one for sending and one for receiving, and to identify the sent and received identification codes. In a wireless transceiver that becomes capable of communication when the codes mutually match, the two types of identification codes are divided into a group identification code and an individual identification code by corresponding digits, and the group identification code is divided into a group identification code and an individual identification code. The identification code is commonly used for the sending and receiving identification codes, and individual calls can be made between each other by sending and receiving the identification code in which only the settings of the individual identification code have been changed. A wireless transmitter/receiver characterized by:

Further, there exists a wireless transceiver in which a group identification code is common and a specific individual identification code is provided separately as a receiving identification code for simultaneous calls. (Operation) Individual calling or group calling is performed as follows between wireless transmitter/receivers configured in this manner and sharing the same preset group identification code. .

Each radio transceiver is preset with an individual identification code for reception (standby) in response to individual calls or general calls. Then, from a certain radio transceiver,
Change the setting of the individual identification code part of the sending identification code to the individual identification code of the person you want to call,
Make a call.

At this time, if the individual identification code is set to the code for simultaneous calling, all other wireless transceivers in the same group other than the self are called.

Also, if you set the individual identification code to the code of the person you want to call and make a call, only the designated wireless transceiver will be called.

In this way, the identification code for sending and receiving is divided into two parts, one for group identification and one for individual identification, and the group identification code can be shared as is, and the settings for the individual identification code can be changed with a simple operation. - General calls or individual calls cannot be performed. This partial operation allows for easy calling, and by sharing the group identification code,
The entire device is easily constructed at low cost.

[Embodiment] Next, an embodiment in which the present invention is applied to a wireless transceiver such as a personal radio will be described with reference to the drawings.

A personal radio is a system that can be called or called only when a five-digit sending/receiving identification code called a calling/standby group number matches. This five-digit identification code is divided into two parts based on the digits, and one part is assigned as a group identification code and the other part is assigned as an individual identification code. The form in which corresponding digits are separated and divided may not be continuous, but may be a discrete combination.

The group identification code is used to separate one group of users of the system from among the many users of wireless transceivers such as personal radios, and the codes are the same within the same group.

The individual identification code is for individually identifying each station within the same group.

As shown in Figure 2, as an example of configuring a system with up to 99 mobile radio stations, the upper three digits are group identification code A''xxx'', and the lower two digits are individual identification code B-C. -D, and the base station individual identification code is “00”.
``From car 1 to car 988'' 01.02...
98'' - Individual identification code D for general calling
99”.

FIG. 1 shows a block diagram of a wireless transceiver. The identification code set for the user operator is determined by the identification code setting sections 10 to 1.
2, and codes corresponding to the set values are generated by the code generation units 20 to 22.

Also, a transmitting section 13, a receiving section 14, and a modem 15 for transmitting and receiving data, and a matching detecting section 16 for detecting whether the received identification code matches the set local address or the general paging code. , and a control section 17 that controls the operation of each of these sections.

Group identification code of the upper three digits of the identification code
As shown in Fig. 2, Xxx''A is the code setting section 1.
It is set to 0, and based on this, the code generators 20 and 21 commonly generate and use it.

The lower two digits of the individual identification code B-D are generated by the code generator 21 for simultaneous calling, the local address C is set by the code setting unit 12, and the code is generated by the code generator 22. It has become. Further, the destination station address B to be called is set each time by the code setting section 11 and generated by the code generating section 20.

As an example, a case will be described in which the base station calls the second car. The base station operator reads the individual identification code B'' for car 2.
02" in the code setting section 11. As a result, the calling identification code "XXXO2" is generated in the code generating section 20. This calling identification code "XXXO2" is
It is transmitted from the transmitting section 13 through the modem section 15.

Car No. 2 has a callee identification code "XXXO2" generated in the code generator 22 as its own address, and the match detector 16 finds that they match, and the call is received.

In this way, a call is started between the base station and the second car.

At this time, the call does not arrive at the other station because the sending/receiving identification codes do not match.

When performing simultaneous calling, calling identification code setting section 1
1 is set to "99" as the individual identification code B. As a result, the transmission code generation section 20 generates the calling identification code "XXX99". When this is transmitted, the call is received because all stations have the called identification code "XXX99". In this way, simultaneous calling is accomplished.

Through the above operations, individual and collective calls within the same group are performed. Note that if a switch that remains in a mechanical state is used in the code setting section, it is possible to replace a part of the code generation section with this switch.

Since the group identification code is 3 digits, 1000
Since it is possible to set up to groups, and each group has a two-digit individual identification code, it is possible to allocate up to 100 stations (-99 stations when numbers are assigned for simultaneous use). The allocation of these numbers of digits can be changed as necessary.

In this way, since the group identification code A is shared, it is only necessary to set the individual identification codes B-D, so if the code setting sections 11 and 12 have a setting function for two digits. Enough. Therefore, the parts cost is low and the space occupied is reduced.

Furthermore, if the calling code setting unit 11 sets only the individual identification code B without changing the group identification code A, the calling operation can be easily performed.

In addition, when changing the group identification code A, all the contents of the code generation units 20 to 22 are rewritten by changing the settings of the code setting unit 10, so the need for double operations is saved. This prevents erroneous operations, incorrect settings, and forgotten changes.

[Effects of the Invention] As described above, according to the present invention, the identification code is separated into a group identification code and an individual identification code, the group identification code is commonly used, and the individual identification code is used for calling other stations. , for local station called, and for general calling, so the number of digits required for setting the individual identification code can be reduced, reducing component costs, saving installation space, and further improving group When changing the identification code, you only need to change it in one place, which simplifies the operation and prevents double work and operational errors.
Various particularly remarkable effects can be obtained.
