DETAILED DESCRIPTION OF THE INVENTION <Industry> Second Field of Application The present invention relates to a waveform monitor device used in an experiment/evaluation system.

BACKGROUND ART Conventionally, when monitoring waveforms in an experiment/evaluation system, a multi-pen recorder (for example, two 12-pen recorders connected) has been used as a monitor and recording device.

<Problem that the invention seeks to solve> In this case, the following problems arise.

■The amount of data (recording paper) is large, making it difficult to store.

■Comparison with past data is difficult to process using a computer because there is no device that can easily read the waveform data on the recording paper.

■Recording paper shrinks and changes depending on temperature and humidity, making manual correction during reading difficult.

■Due to the pen recorder's limited response speed, it is not suitable for monitoring and recording high-speed phenomena.

The purpose of the present invention is to solve these problems,
It is a multi-channel monitoring device that does not use recording paper.
An object of the present invention is to provide a waveform monitor device that can be used by a computer to save data and compare it with past data.

<Means for Solving the Problems> The present invention to achieve the above objects includes an auxiliary storage device for storing data, a keyboard for inputting necessary information, and a man-machine interface with an operator. A color monitor that is used as a first color monitor interface having a function of converting the video signal into a video signal and displaying the video signal on a color monitor according to a television system; The present invention is characterized in that it includes a second color monitor interface that superimposes the signal and sends it to the color monitor.

Function> The video signal from the first color monitor interface is displayed on the color monitor screen. At this time, if the superimpose function of the second color monitor interface is activated according to the specification, an arbitrary area of the color monitor screen can be displayed. It is possible to superimpose the monitored signal waveform that you want to monitor.

This CPU reads the waveform data stored in the auxiliary storage device 6 based on the information input from the keyboard 5, converts it into a video signal, and then displays it on the color monitor 3 in a television format. In this case, the color monitor 3 is used as a man-machine interface with the operator.

(hereinafter referred to as an AD converter) 4 converts the monitored signal digitized and given to a video signal, combines it with the video signal from the first color monitor interface 1, and sends it to the color monitor 3. It is now possible to do so. Note that the first color monitor interface 1 can also store the output of the AD converter 4 in the auxiliary storage device 6 if specified.

FIG. 2 is a diagram showing the configuration of the circuit part related to the synthesis of the video signals, in which the switch 10 is switched by the control signal generated by the timing generator to output the output of the first color monitor interface 1 or the output of the second color monitor interface. One of the skewer forces on the color monitor interface 2 is selected and sent to the color monitor 3.

FIG. 3 is a diagram of the screen of the color monitor 3. By switching the switch 10, a monitor area 8 is set at an arbitrary position on the display area 7 where the waveform data from the first color monitor interface 1 is displayed. The monitored signal from the AD converter 4 can be displayed (superimposed).

The timing generator 9 generates a 3 control signal (switch switching signal) corresponding to the digit 12X1 + X 2 + 3' 1 + 3' 2 of the monitor area 8 in FIG. This X , X2 , 3'1 1 3'
