Abstract

PURPOSE:To execute an exact summing processing by generating a present right time data by integrating summing pulse data for a range within one minute by a primary processor and obtaining the difference of the present right time data of a previous time and this time, and obtaining an every right time data by integrating a pulse after comparing said differential data with predetermined limit data. CONSTITUTION:A time counter 23 outputs a start to a differential data processing part 24 at the rate of once per 10 seconds. The differential data processing part 24 obtains the difference of the present right time data and the right time data of the previous time, and compares this differential data with the limit data to be stored in a limit data memory 25. When a limit value is larger than the differential data, the differential data is added to the counted value of an integrating counter 26. Time, when a device was started by the time counter 23, is decided whether to be a right time or not, and when it is not the right time, a processing is finished. As the result, the every right time data is generated and is written in an every right time data memory 27, and clears the integrated count value into 0.

and a form processing section (29) that performs form processing similarly to the screen display processing section (28).

Next, the operation of the conventional device will be explained based on the above configuration.

First, in the primary processing device (1), an external pulse signal is detected by the detector (11), and the data of the counter 02) is counted up.

Information on this counter (12) is transmitted to the secondary processing device (2) via the transmission path (3).

In the secondary processing device (2), the clock counter (23) is
The differential data processing unit (24) is activated every hour on the hour.

This differential data processing section (24) reads the counter (12) into the current hour data memory (21), calculates the difference from the previous hour data memory (22), and calculates the difference between the counter (12) and the previous hour data memory (22).
7) and store it.

The clock counter (23) also activates the screen display processing section (28) that performs display processing on the CRT (4) and the form processing section (29) that performs printing processing on the typewriter (5). Every hour data is outputted from the hour data memory (27) to the outside.

[Problems to be Solved by the Invention] Since the conventional pulse count processing device is configured as described above, the counter may change to a value different from normal data such as O due to a failure of the primary processing device or due to maintenance. When this happens, there is a problem that every hour data in the secondary processing device becomes invalid data.

This invention was made in order to solve the above-mentioned problems, and aims to provide a pulse count processing device in which every hour data in the secondary processing device does not become invalid data even in the event of an abnormality in the primary processing device. purpose.

[Means for Solving the Problems] The pulse count processing device according to the present invention integrates added pulse data obtained by cyclically adding pulse data from a plant in a primary processing device within a range of one minute. to create current hour data, find the difference between the previous current hour data and the current current hour data, compare this difference data with predetermined limit data, and determine if the difference data is a smaller value. The configuration is such that the data acquisition process is performed by the secondary processing device only in this case.

[Function] When the difference data in this invention is a normal value, a value of several counts below the limit data is obtained, and when the primary processing device is abnormal, it is expected that it will exceed the limit data or become O. During the abnormal time period of the primary processing device, the data can be set to 0 every hour on the hour, thereby preventing the secondary processing device from receiving abnormal data.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

The configuration block diagram of the apparatus of this embodiment is shown in FIG.
The configuration of the conventional device shown in FIG. 3 includes a limit data memory (25) in which limit data in which the limit of differential data is set in advance is stored, and a limit data memory (25) that stores the limit data when the differential data is a smaller value than the limit data. It is configured by adding an integration counter (26) that adds the value to the count value.

In addition, the clock counter (23) in the device of this embodiment outputs activation to the differential data processing unit (24) only once every hour, whereas the clock counter (23) in the conventional device outputs activation to the differential data processing unit (24) only once every hour. Differential data processing unit (24) at a rate of once
Outputs startup to .

Further, in addition to calculating the difference between the current hourly data and the previous hourly data as in the conventional device, the differential data processing unit (24) also calculates the difference between the current hourly data and the previous hourly data.
), and based on the comparison result, a start output signal is sent to the data memory (27), screen display processing section (28), and form processing section (29) every hour on the hour. do.

Next, the operation of the apparatus of this embodiment based on the above configuration will be explained.

FIG. 2 is a flowchart of the operation of this embodiment according to the program, and shows the process from the clock counter (23) to the creation of data every hour after the differential data processing section (24) is activated.

First, the counter (22) of the primary processing device (1) is input to the current hour data memory (21) in the secondary processing device (2) (step l), and this current hour data and the previous hour data memory are input. The data processing unit (24) calculates the difference from the previous hourly data stored in (22) (step 2). Compare the limit data preset in the limit data memory (25) with the difference data of the difference data processing section (24) in (Step 2) (Step 3), and when the limit value ≧ difference data, the integration counter (26) Difference data is added to the count value (step 4).

The clock counter (23) determines whether the activated time is on the hour, and if it is not on the hour, the process is terminated.

As a result, every hour data is created and every hour data memory (
27) (step 6), and the cumulative count value is set to 0.
``Clearly Step 7) New time data processing will be possible from the next startup.

In the above embodiment, the limit data is stored inside the secondary processing device, but it can also be configured to be received from the outside through a contact point.

Moreover, one limit data can be set for the entire plant, or a plurality of limit data can be set for each signal.

[Effects of the Invention] As described above, according to the present invention, the activation interval from the clock counter is shortened so that the pulse count value can obtain a differential value of several counts, and the differential data is set in advance. Since data is obtained every hour on the hour by integrating after comparing with limit data, the effect of eliminating incorrect data and performing accurate addition processing is enhanced.
