Abstract

PURPOSE:To realize the automatic transmission/reception of a message set previously by sending automatically the recorded message to the reception side from a transmission side after confirmation of the coincidence between the identification codes and recording automatically the received message. CONSTITUTION:When the transmission of a message is desired, a radio communication card is set in a transmission mode and an identification code and the relevant message are supplied. A control part 5 transmits the identification code in the timing set optionally and at a prescribed frequency and at the same time keeps a reception state for a fixed period after transmission of the identification code. When an identification code generating/deciding part 2 decides that a desired identification code is received from the remote side, transmission message is read out of a digital voice memory part 4 and transmitted. At the reception side the received message is supplied to a voice CODEC part 3 and stored in the form of the digital voice. Thus it is possible to transmit and receive automatically the message set previously.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of automatically sending and receiving not only real-time messages but also preset messages when the recitation codes match. Regarding the wireless communication cart.

[Prior Art and Problems to be Solved] Conventionally, as this type of wireless communication device with a recitation code, there is a personal wireless communication device. This communication device has a mechanism that allows you to set a specific group number and the other party's radio device with the matching number will emit a calling tone, allowing you to communicate with each other in real time using real voice. .

However, the conventional personal wireless communication device mentioned above is
Since it was intended for real-time communication, there was a problem in that messages could not be sent or received unless the communication partners were able to communicate with each other.

The present invention has been made in view of the above-mentioned problems, and is a wireless communication system that not only automatically calls people whose recitation codes match, but also enables automatic transmission and reception of preset messages. For the purpose of providing cards.

[Means for solving problems] In order to achieve the above object, the wireless communication card of the present invention has the following features:
A means for transmitting or receiving a pre-registered recitation code at a fixed period or arbitrarily set timing, and generating a recitation code at the time of transmission, and combining the received recitation code and an internally set reception permission code at the time of reception. A means of comparing and determining whether there is a match or a mismatch, and when sending,
After confirming that the recitation codes of the sender and the receiver match, the sender automatically sends the recorded message to the receiver, and when receiving the message, the message is automatically recorded. It is.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 shows a block diagram of the machine part in one embodiment of the present invention. In this FIG. 1 is a digital audio memory section, 5 is a control section for controlling each section as a whole, and 6 is an input section, for example, a key input section. Further, 7 indicates a speaker (earphone), 8 indicates a microphone, and 9 indicates the entire wireless communication card.

When inputting a recitation code in a wireless communication card having such a configuration, the necessary number is entered from the key input section 6, and the recitation code generation/discrimination section 2 is input via the control section 5.
Enter.

The transmitted message is input as a voice through the microphone 8, converted into digital voice in the voice codec section 3, and then stored in the digital voice memory section 4.

On the other hand, the received message is input from the wireless transmitting/receiving section 1 as an analog signal to the voice communication section 3, converted into digital voice, and then stored in the received message section of the digital voice memory section 4 as digital voice data. When opening a received message, an appropriate operation is performed on a key manual section 6 to continuously take out the received message from a digital voice memory section 4, convert it into an analog signal through a voice codec 3, and output it as voice from a speaker 7.

Also, wireless transmission and reception is performed using the following procedure.

That is, when there is a message to be sent, the wireless communication cart is set to the sending mode in advance and the recitation code and message to be sent are input. At the same time, the recitation code is transmitted from the antenna la using a predetermined modulation method on a predetermined frequency, and after transmission, the recitation code is kept in the receiving state for a certain period of time to determine whether or not the expected recitation code has been transmitted from the other party. Check that.

Here, if the recitation code generation/discrimination unit 2 determines that the expected recitation code has been sent from the other party,
The message to be transmitted is read from the digital voice memory section 4, converted into an analog signal via the voice codec section 3, and then transmitted from the antenna la of the wireless transceiver section l.

On the other hand, on the receiving side, after sending the recitation code, it waits for a message to be sent from the sending side, and if the above-mentioned message is received via antenna la and wireless transceiver l, Audio codec section 3
After being converted into digital audio, the message is manually input to the digital audio memory section 4 and stored as a received message.

Next, embodiments of the present invention will be described in more detail with reference to FIGS. 2(a) to 2(d).

In FIG. 2(a), a set of two wireless communication carts 9A
, 9B are set to the same recitation code "37814". This recitation code is written in advance as an information collection number in a specific field (for example.

(change information). The wireless communication card 9A on the message sender side digitally records the message "Today..." from the sender.

In Fig. 2(b), the wireless communication card 9A on the message sender side transmits a recited code at regular intervals. put it in your pocket and have it sent automatically.

If the wireless communication card 9B with the same recitation code "37814" happens to be within the receivable range, this wireless communication card 9B receives it, detects a match between the recitation codes, and reads the code as shown in Fig. 2 (c). ), it sends out a "0" signal. Then, the message sender's wireless communication cart 9A receives an "OK" signal, and the message "To" is sent.
day...". The wireless communication cart 9B on the message receiving side receives this transmitted message and automatically stores it in the internal memory 4.

Thereby, as shown in FIG. 2(d), the received message can be heard via the speaker 8 whenever desired.

By adding a secret device to one wireless communication card, it can be used as an effective means for exchanging important messages. Furthermore, if a mode for sending and receiving messages in real time is provided, it is of course possible to send and receive messages in real time.

As described above, according to the present invention, by automatically transmitting and receiving a recitation code and determining whether or not they match, and when there is a match, by automatically transmitting and receiving messages and storing them, , communication regarding specific information can be performed automatically.

■ Automatic and confidential communications regarding specific information with specific parties.

■ Since audio input and output and storage using digital audio memory are performed, only a microphone/speaker (earphone) is required for input and output, making it compact or f7.

[Effects of the Invention] As described above, according to the present invention, it is possible to automatically send and receive messages set in advance.
