Upon the receipt of the ID1 signal addressed to its own station from the opposite station, the recorder 46 starts the talking from the opposite station, and upon the receipt of the ID2 signal addressed to its own station from the opposite station, the recording is stopped, Thus, only the talking of the opposite station and its own station is recorded depending on the type of the ID signals.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio with a recording function for recording the voice of a call partner station.

[0002]

2. Description of the Related Art FIG. 4 shows a timing chart showing the relationship between a call and a recording of a conventional radio with a recording function. Figure 4
(A) is a method of recording in synchronization with a call when the call is started. Recording is started by detecting an audio signal of a predetermined input level or higher in the wireless device. When the call 1 addressed to the own station is received, the recording 2 is started, and when the call 1 addressed to the own station is ended, the recording 2 is also ended. The recording 4 is similarly performed for the response 3 of the own station to the other station which talks with the own station. Further, unnecessary recordings 7 and 8 are also made for the call 5 addressed to another station and the response 6 for the other station corresponding thereto received by the own station. Here, the other station refers to a station other than the partner station which is a partner of the call with the own station. Furthermore, by making recordings 7 and 8, there is a possibility that the memory capacity for recording will be exceeded and the contents of the previously recorded call 1 addressed to itself will be erased.
In a general vehicle-mounted wireless system, since the temperature inside the vehicle becomes high or low, a magnetic tape having a large memory capacity for recording cannot be used, but a semiconductor memory having a small capacity is used.

FIG. 4B shows a system in which recording 11 is started at the same time when the local station calling signal 10 is received from the partner station. Since the ID signal is added to the local station calling signal 10 as identification data addressed to the local station, it is possible to determine the local station calling by detecting the signal. When the local station call signal 10 is received, the call from the partner station to the local station 1
Recording 11 is performed until the end of 3. However, recording from the call 10 addressed to the local station to the start of the local station response 12 and the recording from the end of the local station response 12 to the start of the local station addressed call 13 are wasted.

In FIG. 4C, when the own station is set to be absent, when the calling signal 20 addressed to the own station from the other station is received, the absent signal 21 and the absence message 2 to the other station are sent.
A method of starting recording after transmitting 2 will be described. In this figure, while waiting for a call addressed to the own station from the partner station after starting the recording 23, the recording exceeds the preset waiting period and the recording 23 is stopped. In this way, the partner station terminates the call to itself when it is determined that the partner station is absent. Therefore, the recording device of the partner station may end without recording due to the time-out of the partner station waiting for a response. .

FIG. 4 (D) shows a method of starting recording 36 after transmitting an absence signal 31 when a calling signal 30 addressed to itself is received from a partner station when the own station is set to be absent. Indicates. After starting the recording 36, while waiting for a call addressed to the own station from the partner station, signals and calls between other stations indicated by reference numerals 32 to 35 are received and recorded. In this case, since the time-out waiting for the response from the partner station after transmitting the absence signal 31 is not set, the recording 36 is continued until the call from the partner station addressed to itself is received.

[0006]

In the conventional radio with a recording function, when recording the voice of the call with the partner station, as shown in FIG. Also, while waiting for a response from the partner station, it is wasteful to make a recording.

An object of the present invention is to provide a radio device with a recording function which can eliminate the waste of recording during a call with a partner station and improve the efficiency of recording.

[0008]

According to the present invention, there is provided a radio device with a recording function, which receives and records a voice signal to which identification data is added before and after, and transmits the absence signal when the operator is absent.

A radio device with a recording function, comprising: a control means for starting the recording of a signal and ending the recording when the identification data indicating the end of the audio signal is detected.

[0009]

According to the present invention, in a radio device with a recording function for receiving and recording a voice signal to which identification data is added before and after, and transmitting an absence signal when the operator is absent, the identification data addressed to the own station is provided. Is used, a response means from the local station to the partner station, and a control means are used. The control means responds to the output from the detection means or the response means, starts recording the voice signal only when detecting the identification data addressed to the own station or when responding to the partner station, and detects the identification data indicating the end of the voice signal. The recording ends when you do. Therefore, it is possible to eliminate the waste of recording during a call with the partner station.

1 is a block diagram showing the electrical construction of a radio device with a recording function according to an embodiment of the present invention. When the radio wave is received by the receiver 41 via the antenna 40, the radio wave is demodulated into voice in the voice band and data such as an ID signal. Data such as the demodulated ID signal is converted into digital data by the modem 42. The ID signal is a signal for identifying whether or not a radio wave from an unspecified station is addressed to itself. The demodulated audio signal is amplified by the amplifier 44 and can be heard as audio by the speaker 45. At the same time, the demodulated voice signal is recorded by the recorder 46, and the recorded data is stored in the semiconductor memory 47.

Next, the voice signal input through the microphone 48 is modulated in the carrier wave in the transmitter 49 and transmitted as a radio wave through the antenna 40. at the same time,
The voice from the microphone is recorded by the recorder 46.
In addition, the recorder 46 outputs and sends an absent signal and an absent message in response to a call signal addressed to itself from the partner station when the absence is set. When the voice is input from the microphone 48, the press talk switch of the microphone 48 is pressed, but in synchronization with this, the PTT signal is transmitted from the microphone 48 to the C
It is output to the PU 43. The CPU 43 inputs the ID
The recorder 48 is controlled based on the signal and the PTT signal.

FIG. 2 is a timing chart showing the relationship between the call and the recording of the radio with a recording function shown in FIG. Figure 2
(A) is a case where when the own station is set to be absent, when the call signal 60 addressed to the own station is received from the partner station, after the absence signal is transmitted to the partner station, the call to the partner station of the partner station is recorded. Indicates. Since the calling signal 60 addressed to the own station includes the identification data ID1 for communicating with the own station from an unspecified station, it can be determined that the signal is addressed to the own station. After transmitting the absence signal 61 from the local station, the recording 63 is started by receiving the ID signal 62 addressed to the local station of the partner station as the identification data. Recording 63
Is performed after the end of the call 64 addressed to the own station until the ID2 communication 65 addressed to the own station is received as an identification signal. In this way, by receiving the ID1 signal 62 and the ID2 signal 65 addressed to the own station as the identification data, the transmission data addressed to the own station and the other station can be distinguished, and the start and end of the call can be determined. , You can record only calls to your station.

FIG. 2B shows a case where a call between the local station and the remote station is recorded when the call signal 70 addressed to the local station is received from the remote station. After receiving the calling signal 70 addressed to itself, the ID1 signal addressed to itself is transmitted as identification data, and at the same time, the recording 72 is started. The recording 72 is performed after the call 73 addressed to the partner station is completed until the ID2 signal addressed to the partner station is transmitted as identification data. When the ID1 signal 75 addressed to the local station of the partner station is received after the ID2 signal 74 addressed to the partner station is received, recording 76 is started. The recording 76 is performed after the call 77 to the own station of the partner station is completed and until the own station receives the ID2 signal 78 addressed to the own station as identification data. The ID signal addressed to the other station and the call addressed to the other station, which are denoted by reference numerals 79 to 81, are not recorded by the local station by confirming the ID signal.

As described above, by transmitting the ID1 signal 71 and the ID2 signal 74 addressed to the partner station as the identification data, the start and end of the call can be detected.
Only calls to the other station can be recorded. Also, ID1 addressed to your own station
By receiving the signal 75 and the ID2 signal 78 addressed to the own station as identification data, the transmission data of the own station and the transmission data of another station can be distinguished, and the start and end of the call can be detected. Only recording is possible.

FIG. 3 is a flow chart showing the recording operation of the local station in the radio device with recording function shown in FIG. At step a1, the process is started. At step a2, when the call signal addressed to the own station is received, the process proceeds to step a3. When the call signal addressed to the own station is not received in step a2, the process proceeds to step a10 and it is confirmed whether or not there is a call addressed to the own station. If the own station is set to the absence mode in step a3, the absence signal is returned to the partner station in step a4, the absence message is transmitted, and the process returns to step a2.
If the own station is not set to the absent mode in step a3, the process proceeds to step a5 and returns a response signal to the fact that the own station has received the calling signal. At step a6, the pre-talk switch of the microphone is pressed to turn on the PTT signal.
When it is set to N, an ID1 signal addressed to the partner station, which indicates the start of transmission from the own station to the partner station, is transmitted, and a call is made from the own station. If not transmitted from the own station in step a6, the process proceeds to step a10 and it is confirmed whether or not there is a call addressed to the own station. In step a7, transmission from the own station to the other station is started to make a call, and at the same time, recording is started. At step a8, it is confirmed whether or not the PTT signal is OFF with the press talk switch 4 of the microphone in the original state. Step a8
If the PTT signal is turned off at, the ID2 signal addressed to the partner station indicating the end of transmission is transmitted, and at the same time recording is stopped.

At step a10, since the call to the partner station is completed at step a9, a response to the call to the own station from the partner station is waited for, and whether or not the ID1 signal addressed to the own station indicating the start of transmission of the partner station is received. Check if When the ID1 signal addressed to the own station is received in step a10, the process proceeds to step a11 to start recording the call from the partner station. If the ID1 signal addressed to the own station cannot be received in step a10, the process returns to the initial state of step a2. At step a12, it is confirmed whether or not the ID2 signal addressed to the own station, which indicates the end of transmission of the partner station, is received. When the ID2 signal addressed to the own station is received in step a12, the process proceeds to step a13 and recording is stopped. In step a13,
When the call from the partner station to the own station ends, the process returns to step a6, the call from the own station to the partner station is performed, and the operations of steps a6 to a13 are repeated until the mutual call ends.

[0017]

As described above, according to the present invention, when recording a call with a partner station in a radio device with a recording function, only the call between the partner station and the own station is recorded and unnecessary recording is performed. Not performed. Therefore, it is possible to eliminate the waste of the recording in the call with the partner station and improve the efficiency of the recording.
