Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a data processing device that collects, stores, calculates, and outputs data output from measuring devices such as balances and biochemical analyzers. It is.

(Prior art) The number of output digits of data output from a measuring device is
Depends on the measuring device.

When output data from a measuring device is collected and processed by a data processing device, some processing is performed on the data. In conventional data processing, it is common to collect significant figures of output data as they are.

(Problems to be Solved by the Invention) If the significant figures of output data are collected as they are, inconveniences arise when performing calculations that match the accuracy of the collected data.

An object of the present invention is to extract only the necessary number of digits of data when taking in data from a measuring device, and to ensure consistency with data to be stored or processed.

(Means for Solving the Problems) In the data processing device of the present invention, after collecting data from a measuring device, before displaying it or storing it in an external storage device, the data is Pre-process the data so that it can be manipulated in a way that is truly necessary and useful.

As shown in FIG. 1, the data processing device 1 of the present invention includes a setting section 2 that sets the number of input digits of measurement data according to the type of data from the measurement device, and data set by the setting section 2. an input digit number storage unit 4 that stores input digit numerical values according to the type of , and a data collection unit 8 that collects output data from the measuring device 6
Based on the number of input digits set in the input digit number storage unit 4, arithmetic processing is performed to align the number of digits in the input data of the data collection unit 8 according to the type of data, and the number of digits of the measured data is made smaller than the digit setting value. The calculation control section 10 outputs an overflow signal when the overflow signal is also large. 12 is an output control section, and 14 is a printer.

(Operation) The operation of the present invention will be explained with reference to FIGS. 1 and 2.

The number of input digits is set in advance from the setting unit (for example, a keyboard) 2, and stored in the input digit number storage unit 4 divided into an integer part and a decimal part. If there are multiple types of data input, a plurality of input digits (n in the figure) are stored.

If there is data input from the measuring device 6, the data collection unit 8 receives the data (step S1)
At the same time, the arithmetic control section 10 retrieves the digit setting value from the input digit number storage section 4 according to the type of data (step S2), and controls the result to the data acquisition section 8, which then follows it. data collection.

Data collection is performed as follows.

If the number of digits in the integer part of the measurement data is less than or equal to the digit setting value for the integer part, and the number of digits in the decimal part of the measurement data is also less than the digit setting value for the decimal part (step S3,
S4), the measurement data is collected as is and sent to the calculation control section 10. (Step S5).

If the number of digits in the integer part of the measurement data is less than or equal to the digit setting value for the integer part, but the number of digits in the decimal part of the measurement data is greater than the digit setting value for the decimal part, the measured data will be adjusted according to the digit setting value for the decimal part. After rounding off the number of decimal digits, the measured data is sent to the calculation control unit 1.
0 (steps S3, S4→S6→S5).

After performing necessary arithmetic processing on the data, the arithmetic control section 10 outputs the results through the output control section 12.

If the number of digits in the integer part of the measurement data is larger than the digit setting value for the integer part, a message indicating that the number of digits has overflowed is sent to the output control section 12 (steps S3→S7).

(Example) FIG. 3 represents one embodiment.

20 is a CPU, which realizes the data acquisition section 8 and the calculation control section 10. 22 is a memory device as the input digit number storage section 4; The measuring device 6, the keyboard 2 as a setting section, and the printer 14 are connected to this CPU system via interfaces 24, 26, and 28, respectively.

In FIG. 1, the number of output digits of data output from the output control section 12 may be set independently of the number of input digits. In that case, the number of output digits from the data processing device of the present invention can be different from the number of input digits.

(Effects of the Invention) Since the data processing device of the present invention sets the number of digits of the data to be collected to a preset number of digits,
The following effects can be achieved.

(1) Consistency between imported data and post-processed data is achieved, increasing the value of the raw data.

(2) Depending on the purpose, the reliability of arithmetic operations between data processed according to the present invention is higher than that of arithmetic operations between data that only have the same significant figures.

For example, GLP (Good
This is especially useful for dealing with safety tests such as laboratory practice.

(3) When data with a larger number of digits than the digit setting value is supplied from the measuring device, this can be immediately displayed on a printer, etc., and the set number of input digits can be changed. .
