Abstract

PURPOSE:To automatically record time without audio recording time and to reproduce accurate measuring time by providing a CPU for recording and reproducing measuring time. CONSTITUTION:When the recording mode is selected by a recording/reproducing selection switch 3, data from a measuring instrument, etc., coupled with an external monitor terminal 7 are fed to a recording section 1 consisting of a tape recorder, etc. Simultaneously, time is processed as 10sec, 1min and 10min, etc., from set time by internal clocking counting in conformity with program processing by the CPU 4, and the time data are outputted by a UART to be automatically recorded to the recording section 1, not by audio recording. The measuring time thus recorded is reproduced by a reproducing section 2 under the reproducing mode to obtain accurate measuring time.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a recording/reproducing device.

[Conventional technology]

FIG. 6 is a system diagram of an example of a conventional recording and reproducing device. In the diagram, 1 is a recording section, 2 is a reproduction section, 3 is a recording/reproduction selection switch for selecting a recording mode and a reproduction mode, and 6 is a recording data Input terminal 7 is an external monitor terminal for monitoring recorded data and re-output data.

Next, the operation will be explained. When recording data, a recording mode is selected using the recording/reproduction selection switch 3, and data is input from the recording data input terminal 6. Data is recorded in a recording unit 1 comprising a tape recorder or the like, and is also connected to a general-purpose measuring device or the like through an external monitor terminal 7 for recording (or monitoring). To play data, record/
The reproduction mode is selected with the reproduction selection switch 3, and the recording data input terminal 6 is disconnected. Recorded data is read from the recording section I and output to the reproducing section 2, which is composed of a pen-written oscillograph or the like. It is also possible to record (or monitor) this by connecting it to a general-purpose measuring instrument or the like through the external monitor terminal 7.

[Problem that the invention seeks to solve]

Since conventional recording and reproducing devices are configured as described above, the measurement time must be recorded by voice recording, etc., and therefore a measurement person is required to be present during recording and reproduction. However, there were other problems such as the playback time being inaccurate.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a recording/reproducing device that can automatically record time and accurately reproduce time.

[Means for solving problems]

The recording and reproducing apparatus according to the present invention is provided with a CPU section for recording and reproducing measured times.

[Effect]

In the recording and reproducing apparatus according to the present invention, since the CPU section converts the measured time into data and records it, the recording and reproducing of data can be automated and accurate time data can be obtained.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 1 is a recording section, 2 is a playback section, 3 is a recording/playback selection switch that selects the recording mode and playback mode, 4 is a cpU section that converts measurement time into data, and 5 is an output from the recording section 1 to the playback section 2. 6 is a record data input terminal; 7 is an external monitor terminal for monitoring recorded data and playback data; 8 is an interface circuit for outputting playback time data;
is a printer.

Next, the operation will be explained. When recording data, a recording mode is selected using the recording/reproduction switch 3, and data is input from the recording data input terminal 6. Data is recorded in a recording unit 1 consisting of a tape recorder, etc., and is also recorded (or monitored) by connecting it to a general-purpose measuring device through an external monitor terminal 7.
seconds) is converted into data by the 020 unit 4 and output to the recording unit 1 via the serial interface. Data conversion of measurement time is 02
This is done by executing the program shown in FIG. 2 using part 04. The process is as follows.

■ Set the measurement time.

■ Update the above set time every second using the internal clock.

■ The second value of the time is N seconds (N=0.10.20°30.
40.50 or less), a 10-second process is performed.

■ When processing for 10 seconds, time data is output via the serial interface.

■ The 1-minute process is executed when the second value of the time reaches 00 seconds.

(1) 1 minute processing updates the time every 1 second, and outputs time data via the serial interface when the second value of the time reaches 3 seconds (or 2 seconds).

■ When the minute value of the time reaches N minutes (N is the same as above), perform 10-minute processing.

(1) In the 10-minute process, the time is updated every second, and when the second value of the time reaches (N+5) seconds, the time data is output via the serial interface.

■ From then on, repeat ■ to ■ until the measurement is completed.

When reproducing data, a reproduction mode is selected with the recording/reproduction switch 3 and the recording data input terminal 6 is disconnected. Recorded data is output from the recording section 1, and the data is reproduced by the reproduction section 2, which is composed of a pen-written oscillograph, etc.
It is played back (monitored) by connecting it to a general-purpose measuring device or the like through the external monitor terminal 7.

The time data is reproduced (monitored) in the same manner as other reproduction data, and is returned to time in the 020 section 4, and is displayed and output to a printer. Since the time data output from the 020 section 4 uses a serial interface such as a known asynchronous method, the time data output from the recording section 1 during reproduction is the serial data shown in FIG. If this time data is directly input to the reproducing unit 2, it may damage the reproducing unit 2. For example, if the reproducing unit is a pen-written oscillograph, the data in 3 (bl), which damages the pen, etc. Therefore, an interface circuit 5 is provided to prevent the playback unit 2 from being damaged.In the case of the pen-written oscillograph described above, waveform shaping using a capacitor etc. The interface circuit 5 generates a waveform that can be recorded as shown in Figure 3 (C1). Figure 4 shows an example of the pen-written oscillograph and the time data reproduced on the printer ((a) shows the pen-written oscillograph output. , (b) are printer outputs).The year, month, and day 1:00 of the time can be determined by comparing with the data output from the printer.

In the above embodiment, an example was shown in which time data is recorded/reproduced by the CPU section, but as shown in another embodiment of the present invention shown in FIG. C
Data that has been connected to the PU unit 4 and subjected to calculation processing may be recorded/reproduced using a similar method. 9 in the diagram is CP
The U section is a processing data input terminal, and 10 is a calculation processing data external monitor terminal.

〔Effect of the invention〕

As described above, according to the recording and reproducing device according to the present invention,
Since a CPU unit for recording and reproducing measurement time is provided, data recording and reproduction can be automated, accurate time data can be obtained, and data analysis can be performed accurately and easily.
