Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an XY recorder having an XY plotter function.

2. Description of the Related Art Conventionally, as shown in FIG. 7, an XY recorder converts two types of analog input data into digital input data using A-D converters respectively assigned to an X channel 101 and a Y channel 12. From D conversion data to XY
After creating plot data and storing it in the XY RAM,
An XY record, for example, an XY waveform 18, is drawn on the recording paper 16 of the recording device in response to a print command from the operation unit 14. At that time, in order for the user to print comments (characters), axes, scales, etc. on the same recording paper 16 as the XY waveform, the user must generate an XY analog waveform that matches the figure he wants to draw.
X channel 10. It is necessary to provide each to the Y channel 12. For example, as shown in FIG. 8, the letter N shown in FIG.
To draw a complex analog input waveform (Y waveform), a complex analog waveform in which the voltage V shown in Figure 8 changes according to time t is applied to the X channel 10. Must be given to 12.

Problems to be Solved by the Invention However, it is not easy to draw such characters, axes, scales, etc. by generating XY analog waveforms suitable for the types of graphics.

The present invention has been made by focusing on such conventional problems, and has an XY plotter function that allows necessary figures to be easily drawn on recording paper on which XY plot data created from A-D conversion data is printed. The purpose is to provide an XY recorder.

Means for Solving the Problems Means for achieving the above object will be explained below using FIG. 1 showing the present invention.

The input section of this XY recorder having an XY plotter function includes an A-D converter 2.2 that converts two types of analog input data into digital input data, and an input control section 24 that receives input codes from an external controller. The input processing unit is equipped with XY data from two types of AD conversion data.
A recorder XY plot data creation means 48 for creating plot data and a plotter XY plot data creation means 50 for creating XY plot data according to the type of figure specified by the input code are provided, and the created XY plot data can be Via the memory 42 for storing, the output section has the following information:
It is equipped with a recording device 36 that reads XY plot data from a memory 42 and prints it on recording paper.

action The above means works as follows.

Two types of analog data input from the X channel 28 and the Y channel 30 are respectively converted into digital input data by an A-D converter provided in the A-D converter 22. Further, the input control section takes in the code input from the interface 32 connected to the external controller. Recorder XY plot data creation means 4 from the two types of A-D conversion data taken in along this time series
Step 8 creates XY plot data. Also, from the input code, the plotter XY plot data creation means 50 creates XY plot data according to the type of figure specified.

The created XY plot data is stored in the memory 42. The recording device 36 reads the XY plot data from this memory 42 and prints it on recording paper. Therefore, a record based on the A-D conversion data and a figure based on the input code can be simultaneously printed on the recording paper.

Example Hereinafter, the present invention will be described in detail based on the accompanying drawings.

Figure 2 shows an XY plotter function to which the present invention is applied.
FIG. 2 is a block diagram showing the configuration of a Y recorder. In the figure, 20
is an XY recorder with an XY plot function, 22.24
．． 26 is an A-D converter and an input control unit in the input section;
This is the operation section. This A-D converter 22 is equipped with an A-D converter for each of the X channel 28 and Y channel 30, and two types of voltages entering each channel 28, 30,
Converts analog data such as current and power into digital data. The input control unit 24 takes in various codes input from an interface 32 connected to an external controller. Further, the operation unit 26 is equipped with various switches, and by operating the keys, it is possible to perform processing that corresponds to various codes input from an external controller. However, there is no switch corresponding to plotter commands. Therefore, the operation section 26 is not suitable for these processes.
It is not necessarily necessary to provide. In this way, two types of rare A-D conversion data are imported in chronological order,
The code input from the external controller enters the device 34 equipped with a CPU, where it creates XY plot data from two types of A-D conversion data, and creates XY plot data according to the type of figure specified by the input code. Then, processing necessary for printing, such as storing the XY plot data in memory, is performed. A recording device 36 such as a dot printer is connected to the device 34 equipped with this CPU.

The device 34 equipped with the above-mentioned CPU includes, for example, a CPU (central processing unit) 38 and a ROM (read-only memory) 40.
A microcomputer consisting of an SRAM (readable/writable memory) 42, an input/output port 44, a pass line 46, etc. is used.

The CPU 38 corresponds to the central brain of a microcomputer, and according to instructions from the program, controls the entire system, performs arithmetic and logical operations, and temporarily stores the results. It also controls peripheral devices. The ROM 40 contains a control program for controlling the entire XY recorder, an XY plot data print processing program for two types of A-D conversion data and input codes, and XY plot data corresponding to the types of axes, scales, characters, and other figures. Creation data etc. are stored. Further, the RAM 42 stores normal data, XY plot data, etc. of calculation results by the CPU 3B. In addition, R
Instead of dividing the AM 42 into a normal data storage section for calculation results by the CPU 38 and an XY plot data storage dedicated section (XY RAM), it is also possible to separately provide a RAM dedicated to storage of XY plot data. The input/output port 44 includes an A-D conversion section 22, an input control section 24, an operation section 26, and a recording device 3.
6 is connected. The path lines 46 include address bus lines, data bus lines, control path lines, etc. for connecting them.

Next, the operation of this embodiment will be explained.

3, 4, and 5 are flowcharts consisting of steps P1 to P23 showing an example of an XY plot data print processing program for AD conversion data and input codes. To run this program, first
Clear all the XY plot data in the XY RAM 42 and initialize it.

Next, the process goes to P2, and it is determined whether there is an input code from the external controller. If the input code is valid, go to P3' and input the code. Next, the process goes to P4, where a code is input and it is determined whether the jqed command is a recorder command or a plotter command. If it is a recorder command, go to P5,
It is determined whether the instruction is an instruction to set conditions necessary for various processes or a process execution instruction. If it is a condition setting command, go to P6 and set various conditions. If it is a processing execution command, go to P7 and check whether the command is a 5TART command or not.
Determine whether it is a CLEAR instruction or a PRINT instruction. 5TA
In response to the RT command, the process goes to P8, and the XY plot data created from the A-D conversion data obtained according to the set conditions is stored in the XY RAM 42. P9 for CLEAR command
Go to and clear the XY RAM42. Also, PRIN
The T command goes to plO and prints the XY plot data etc. stored in the XY RAM 42 on the recording device 36. Next, the program goes to Pll and determines whether or not to end the processing by this program. If it does not end, return to P2.

If P4 is a plotter command, the process goes to P12, and it is determined whether the command specifies plotting of an axis, scale, character, or any other type of figure. If it is an axis drawing command, go to p13 and draw the XY according to the specified axis.
Data for creating plot data is selected from the ROM 40, the created XY plot data is stored in the XY RAM 42, and the process goes to Pll. In the case of a scale drawing command, a character drawing command, or other types of drawing commands (line, circle, graph, etc.), the process goes to P14, P15, and P1B, performs similar processing, and goes to Pll. Therefore, as a plotter command from an external controller, for example, "' L B N
By simply transmitting ``, the character ``N'' shown in FIG. 8A can be easily drawn.

If there is no external input in the previous P2, p17 is doubled, and it is determined whether there is a switch input by key operation.

If there is a switch input, the process goes to P18, and it is determined whether the switch is a condition setting switch or a process execution switch.

With the condition setting switch, go to Pl9. Further, the process execution switch goes to P2O, and it is determined whether the switch is a 5TART switch, a CLEAR switch, or a PRINT switch. 5TART switch to p21, CLEA
For R switch, go to P22, for PRINT switch, go to P2
Go to 3. The processing performed at these Pl9, P21, P22, and p23 respectively is P6 and P8 according to the input code.
, P9, and Plo. Therefore, all other processes unrelated to plotter commands can be performed by switch input. In this way, the XY recorder function and the XY plotter function can be used at the same time.
Based on data obtained by A-D conversion of analog input data such as measured current, voltage, and power as shown in the figure
2 and a figure such as the axis 54 based on the input code can be easily printed on the same recording paper 56.

According to the present invention, which has been described in detail, necessary figures can be easily drawn on recording paper on which XY plot data created from AD conversion data is printed.
