DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention enables not only real-time message transmission but also automatic transmission / reception of preset messages when the password codes match. Wireless communication card.

[Prior Art and Problems to be Solved] Conventionally, as a wireless communication device with this code, there is a communication device for personal wireless. This communication device has a function that, if a specific group number is set, a radio device on the other side having the same number transmits a ringing tone, and can perform real-time communication with each other by real voice.

However, the conventional personal wireless communication device described above,
It is intended for real-time communication, and there is a problem that messages cannot be sent and received unless the communication partners can talk with each other.

The present invention has been made in view of the above problems, and wireless communication that enables not only automatically calling those having the same code but also automatically transmitting and receiving a preset message. The purpose is to provide a card.

[Means for Solving Problems] The wireless communication card of the present invention achieves the above object.
Pre-registered memory code is sent autonomously at a fixed cycle or at an arbitrarily set timing, and means for staying in a receiving state for a certain period after transmission, and a memory code is generated at the time of transmission and received at the time of reception Means of comparing the secret code and the reception allowable code set internally to determine match / mismatch, and at the time of transmission, after confirming the coincidence of the secret code of the sending side and the receiving side, it is recorded from the sending side. It automatically sends the received message to the receiving side, and at the time of reception, after confirming the encryption code, it automatically records the received message automatically.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a functional block diagram in an embodiment of the present invention. In FIG. 1, 1 is a wireless transmission / reception section, 1a is an antenna, 2 is a code code generation / discrimination section, 3 is a voice codec section, 4 is a digital voice memory section, 5 is a control section for controlling each section as a whole, An input unit 6 is, for example, a key input unit. Further, 7 is a speaker (earphone), 8 is a microphone, and 9 is the entire wireless communication card.

When inputting a password code in the wireless communication card having such a configuration, a necessary number is entered from the key input unit 6 and the password code generation / determination unit 2 is input via the control unit 5.
To enter.

The input of the transmission message is voice-input through the microphone 8, converted into digital voice in the voice codec unit 3, and then stored in the digital voice memory unit 4.

On the other hand, the received message is input from the wireless transmission / reception unit 1 to the voice codec unit 3 as an analog signal, converted into digital voice, and then stored as digital voice data in the reception message unit of the digital voice memory unit 4. When opening the received message, an appropriate operation is performed on the key input unit 6, the received message is continuously taken out from the digital voice memory unit 4, converted into an analog signal through the voice codec unit 3, and output as voice from the speaker 7.

Also, wireless transmission / reception is performed in the following procedure.

That is, when there is a message to be transmitted, the wireless communication card is set in the transmission mode in advance, and the password and the transmission message are input. As a result, the control unit 5 autonomously transmits a code code from the antenna 1a at a predetermined frequency at a predetermined interval or at an arbitrarily set timing according to a predetermined modulation method, and after receiving the fixed code for a predetermined period. The state is checked, and it is checked whether the expected memory code is transmitted from the other party.

Here, if it is judged by the memory code generation / determination unit 2 that the expected memory code is sent from the other party,
The transmission message is read from the digital voice memory unit 4, converted into an analog signal via the voice codec unit 3, and then transmitted from the antenna 1a of the wireless transmission / reception unit 1.

On the other hand, on the receiving side, after sending the encryption code, it is waiting for a transmission message from the transmission side, and if the reception message described above is received via the antenna 1a and the wireless transmission / reception unit 1, immediately. Audio codec section 3
Is input to the digital voice memory unit 4 after being converted into digital voice, and is stored as a received message.

Next, the embodiment of the present invention will be described more specifically with reference to FIGS.

In FIG. 2 (a), a set of two wireless communication cards 9A, 9
Suppose B was set to the same code code "37814". It is assumed that this secret code is known in advance as an information collection number (for example, fishing information) in a specific field. Wireless communication card for message sender
9A digitally records the message "Today ..." as the sender.

FIG. 2B shows a state in which the wireless communication card 9A on the message sender side transmits a reciting code at regular intervals. As a concrete example, put it in a bag or a pocket of clothes while commuting, and have it automatically sent.
By chance, if the wireless communication card 9B in which the same memory code "37814" is set is within the receivable range, this wireless communication card 9B receives it and detects the coincidence of the memory code, and FIG. 2 (c). Send the "OK" signal as shown in. Then, the wireless communication card 9A on the message sender side
The K ”signal is received and the transmission message“ Today ... ”is transmitted. The wireless communication card 9B on the message receiving side receives this transmission message and automatically stores it in the internal memory 4.

As a result, as shown in FIG. 2D, the received message can be heard via the speaker 8 at any time.

By adding a confidential communication device to this wireless communication card, it can be used as an effective means for exchanging important messages. In addition, if a mode capable of transmitting and receiving in real time is provided, it is of course possible to transmit and receive messages in real time.

As described above, according to the present invention, by automatically transmitting and receiving the password code and determining whether or not the code is coincident with each other, and when they are coincident with each other, the message is automatically transmitted / received and stored, whereby an unspecified partner Communication can be automatically performed regarding specific information.

Communication can be automatically made secret with respect to a specific person and specific information.

Since the input and output by voice and the storage by the digital voice memory unit are performed, only the microphone / speaker (earphone) is required for input and output, and miniaturization is possible.

[Effect of the Invention] As described above, according to the present invention, there is an effect that a preset message can be transmitted and received completely automatically.
