It has an input unit 17, a monitoring signal output unit 18 for outputting a monitoring signal, and the like, and has a function of inputting a condition setting control signal.

Reference numerals 6 and 7 denote an internal analog tape recorder and a digital recorder for recording the audio signal from the microphone amplifier 11, respectively. Reference numeral 8 denotes an audio amplifier for sending an audio signal to an external analog tape recorder and digital recorder via an audio signal line 9.

A first interface (A) 2 receives a signal from the control unit 1 and converts the signal into a digital signal.
Reference numeral 4 denotes a CPU that performs arithmetic processing on the signal converted by the first interface (A) 2 and outputs a data signal for driving the internal recorders.

Reference numeral 3 denotes an output data signal which has been processed by the CPU 4 when a voice is recorded / reproduced with respect to an external device such as an externally connected analog tape recorder and digital recorder, as a control signal to the external device. The second interfaces (B) and 5 for conversion are modems for sending output signals from the second interface (B) 3 to the external data line 10.

The CPU 4 has a display function of receiving the operation status of the external recorder after driving as a monitoring signal by the modem 5 and displaying the monitor on the control unit 1 on the operation console at a time.

Next, a description will be given of a case of recording / reproducing and controlling / monitoring the analog tape recorder 6 and the digital recorder 7 provided inside the operation console. First, the control unit 1 of the operation console
Type more control signals C ₁ -C _n, selects the unit to operate. Next, select the mode of operation device by the control signal E ₁ to E _n, further sets the TIME DATA by Data signals A ₁ to A _n. By completing this setting, the analog tape recorder 6 and the digital recorder 7 built in the operation console can be brought into the operating state.

These set control signals and Data signals are converted into parallel digital signals by the interface (A) 2 and input to the CPU 4. The digital data input to the CPU 4 is output from the CPU 4 after performing predetermined arithmetic processing, and returns to the interface (A) 2. The interface (A) 2 converts the digital control signals and digital data required for the analog tape recorder 6 and the digital tape recorder 7 into digital data, which are then input to the respective recorders, and the recorders are activated.

Further, the audio signal input from the MIC AMP 11 of the control unit 1 is input to each recorder and recorded. The operation state of the recorder is as follows: Data A ₁ through the signal route of interface (A) 2 → CPU 4 → interface (A) 2 → control unit _1.
ＡA _n and monitoring signals G _{1 to} G _n are converted by the control unit 1 and output as monitoring signals indicating the recording operation state of the device.

Next, the operation of recording / reproducing control and monitoring of a recording device externally connected to the operation console will be described. Control signals C ₁ -C _n described above, select LINE in addition to the control signal D ₁ to D _n of E ₁ to E _n, select the XMTR (transmitter) by the control signal F ₁ to F _n, Additionally, Data signals A ₁ to A _n by Time Data
Will be set. Upon completion of this setting, the operation console sets the externally connected recorder to an operable state.

Next, the signal flow will be described. The signal input from the interface (A) 2 to the CPU 4 is converted into an RS232c code by the interface (B) 3 and input to the modem 5. The signal input to the modem 5 is further converted to a signal of 1 MBPS or less, and then passes through the data line 10 to drive an externally connected recorder.

The audio signal input from the MIC AMP 11 of the control unit 1 passes through the audio amplifier 8 and the audio signal line 9 and is input as an audio input of an external recorder.

Further, the operation state after the recording is reversed from the above-mentioned drive signal to the external recording equipment → the data line 10 → the modem 5 → the interface (B) 3 → the CPU 4 → the interface (A) 2 → the control unit 1. and is input after being signal-converted by the control unit 1, Data signal B ₁ .about.B _n, and is output as a monitor signal G ₁ ~G _n.

As described above, the recording / reproducing control device of the airport information providing device performs the control of the device and the data processing.
By adopting the digital arithmetic processing technology, it is possible to control and monitor a plurality of analog tape recorders and digital recorders.

[0022]

As described above, the airport information provision of the present invention is as described above.
According to the recording / reproduction control apparatus of the test device, an analog tape recorder, to di diethylene Tal recorder, as well as enabling multiple connections, to the console inside the recording device or external recording device from the operation console unit, Didjitaru Since control and digital data processing are performed, hardware simplification, data transmission speed and control speed can be increased, and device reliability can be improved.
