DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for collecting, integrating, and recording counter values of weighing counters such as a wattmeter counter and a rain gauge counter by a data processing device via a communication line.

[0002]

2. Description of the Related Art An example of a conventional data collection method of a weighing counter will be described with reference to FIG. In this type of data collection method of a weighing counter, a weighing counter 1 such as a wattmeter counter or a rain gauge counter is transmitted to a central input device 2 via a communication line at a constant cycle or when the counter value changes. When the counter value is passed from the input device 2 to the data processing device 3, the counter value is used for measuring and recording the amount of the counter that has increased within a certain period of time. The counter value received by the data processing device 3 is stored in the counter storage unit 4 of the storage device 4 by the weighing counter recording unit 32.
Recorded in 2. The weighing counter integrated value calculation and recording means 34 calculates the integrated value from the difference between the previous counter value and the current counter value in the counter storage unit 42, records the integrated value in the counter integrated value storage unit 44, and sends it to the output device 5 as necessary. Is output.

[0003]

However, the above method has the following problems. The first problem is
If the weighing counter is replaced for periodic calibration or the like, the integrated value may not be correct.

The first reason is that, in the conventional data collection method of the weighing counter, there is no means for recognizing the exchange in the data processing device, and the initial value of the counter after the exchange is irrelevant to the counter value before the exchange. This is because, despite the value, the erroneous integrated value is calculated with the discontinuous counter value as normal.

[0005] The second reason is that the weighing counter cannot be weighed from the time of removal to the time of attachment when replacing the weighing counter.
This is because the increment during that time is not included in the integrated value.

A third reason is that as a procedure for periodically calibrating the weighing counter, a temporary weighing counter is attached as a substitute until the periodic calibration of the removed weighing counter is completed. However, the weighing counter has a different power according to each weighing counter and the power during the attachment of the temporary weighing counter is different, so that the integrated value is incorrect.

The second problem is that even if an incorrect integrated value is manually corrected later, the time required for manual work by the operator is greatly increased.

The reason is that the operator must manually record the counter value before and after replacement, the counter value at a fixed time, and each multiplication factor at the site, and manually calculate the integrated value from these records. This is because the data processing device needs to correct the output result to the input or output device. In general, many weighing counters of this type are often installed, and the number of periodic calibrations increases according to the number of installations.
Manual calculations and data correction work also increase.

Accordingly, an object of the present invention is to provide a data collection method for a weighing counter that can automatically record the counter values before and after the replacement when the weighing counter is replaced.

Another object of the present invention is to provide a weighing counter data collection system capable of automatically calculating and recording a correct integrated value when the weighing counter is replaced.

Still another object of the present invention is to provide a data collection method of a weighing counter which can set a multiplying factor per counter for each replaced weighing counter when replacing the weighing counter.

Another object of the present invention is to provide a data collection method for a weighing counter that can add missing integrated values when the weighing counter is replaced.

Next, the operation will be described with reference to FIGS. 3, 4, and 5. FIG. The counter value of the weighing counter 1 input from the remote monitoring device slave station 21 is transmitted to the remote monitoring device master station 23 through the communication line 22 when a certain period or a change greater than a certain change width is transmitted.

[0041]

According to the present invention described above, the following effects can be obtained.

The first effect is that even if the weighing counter is replaced, an accurate integrated value is calculated and recorded. As a result, there is no need to perform manual calculations later, and the number of work steps can be reduced. The reason is that the storage unit is separately prepared for each exchange in the storage device, and when the weighing counter is exchanged, the weighing counter exchange detection means and the counter selection unit switch the storage destination of the storage unit, and the integrated value is calculated separately. This is because the sum obtained after the calculation is used as an integrated value.

The second effect is that the data is valid even when the data is replaced with a temporary weighing counter. As a result, there is no need to perform manual calculations later, and the number of work steps can be reduced. The reason is that a storage unit for the multiplication factor for each exchange is prepared in the storage device, and this multiplication factor is used when calculating the integrated value.
