Abstract

PURPOSE:To attain arbitrary control, by separating analog and digital output items outputted in advance respectively, storing input point and output data range at each output item as a table and selecting the output item depending on analog and digital signals arbitrarily. CONSTITUTION:The system is provided with a computer 1 storing various data and processing the operation according to a prescribed program, an operation console 2 to set start and stop time of a pen recorder 4 and the output data range, and a CRT display 3. Analog output item and digital output item outputted from the recorder 4 are separated in advance and the input point and output data range are stored in the storage device of the computer 1 at each input item as a table. Further, the table corresponding to the registered output item is referenced as to the registered start and stop time in response to the registration of the desired output data range of the operation console 2, the data of the input point as to the output item is read, the proportional operation is applied to the registered data range and outputted on the recorder 4.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a system for operating a pen recorder via a computer or the like and freely selecting analog output items and digital output items when using a pen recorder. You can start, stop, and expand the data output.

The present invention relates to a recorder control method in which reductions can also be freely performed.

[Technical background of the invention]

(Recorders are widely used in various fields for storing analog data.

Conventionally, by turning on the 10K source, the pen recorder operated at a selected constant speed and specific analog data connected to the pen recorder was output. (In many cases, the installation position of the recorder was also fixed in advance.

Therefore, if it is desired to simultaneously record analog input data from various facilities located far apart, it is necessary to prepare separate pen recorders. This increases costs,
Moreover, a separate place was required to install the recorder.

Furthermore, the output data can only be output within a certain data range, and if accurate data is to be obtained only during a certain time period, a person must change the output range each time. Furthermore, since the output range can only be changed over a few turns, the obtained data changes only over a few turns.

However, in reality, when using a digital recorder, it is often necessary to select not only analog output items, but also digital output items used to calculate the important number of runs of a power machine or the operating time. ,
It is often desirable to enlarge or reduce data based on the recorded in-recorder start/stop times and output data range.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a pen recorder control method that can arbitrarily select output data items, either analog or digital, and can also arbitrarily turn on/off the pen recorder or enlarge/reduce data output.

[Summary of the invention]

The present invention distinguishes analog output items and digital output items to be output by a pen recorder in advance, and stores in a storage device analog and r-internal data tables that tabulate input data and output data ranges for each output item. Then, according to the registration of the output items by input operation, the start/stop time of the pen recorder, and the desired output data when outputting data, refer to the data table corresponding to the registered output item within the registered start/stop time. The system is characterized in that it reads the input data for the output item, performs a proportional calculation on this data based on the registered output data range, and outputs the predetermined data to the recorder.

[Embodiments of the invention]

FIG. 1 shows a system configuration of an embodiment of the present invention.

As shown in Figure 1, this system uses a computer 1゜ operation IL.
j, a cRT (cathode ray tube) display device 3 and a pen recorder 4). Calculation result 1#'i, stores various data described later, and stores them in a predetermined! Perform calculations according to the program. Further, the operation console 2 is used when the start/stop time of the pen recorder 4 sets the output data range.

The read data is displayed on the CR7 display device 3. (
The output to the recorder 4 is controlled by instructions from the computer 1.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

First, using the CR7 display device 3 and the operation console 2, it is checked whether the operator has recorded the output items in advance (P1), and if no output items have been registered, the control ends. As output items, the name of the item desired to be output, the start/stop time for starting/stopping the pen recorder 4, and the data range used for data output are registered using the CR7 display device 3 and the operator console 2. It is assumed that for one item, the start/stop time and data range can be set for up to four turns, for example. In addition, the selection of items is
It can also be done freely and easily by using data files that are divided into various types of equipment. If there are output items, compare the current time with the registered start/stop time (process p2), and if it is not within the start/stop time, check whether all output items have been completed. Check, go to routine (process P1).

If it is within the start/stop time, it is checked whether the output item is analog (process p3). Here, we will explain the case where it is an analog input item.

First, the output items are selected from the analog data chisel in which analog input points, output data ranges, etc. are registered (P4), and the analog input data is Reading is performed (process P5).

Next, based on the output data range, output data is calculated by proportional calculation using the calculation formula Y-aX+b (process P6), and data is output in the output range from 0 to IOV (process P1). After data output is complete, check whether all output items have been output (P8).
If all the steps have not been completed, the process returns to process P1. When all output items are completed, the control ends.

Similarly, when the output item is digital, processing P3 to P8. Controlled through P9.

In this way, the number of pen recorders can be reduced and the pen recorders can be used effectively. Furthermore, since both digital items and analog insect eyes can be registered, e.g.
Number of pumps in operation.

It is possible to simultaneously output comparison data between operating time and pump output flow rate. Furthermore, by changing the output data range and start/stop time, it is possible to more accurately obtain data on output items in a certain time period.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the spirit thereof.

〔Effect of the invention〕

According to the present invention, it is possible to arbitrarily select output data items, either analog or digital, and to provide an output control method (starting/stopping the recorder or scaling up/down the data output as desired).
