Abstract

PURPOSE:To reduce the cost and moreover, to reduce a possibility of the occurrence of an aggregate miss by transferring data between plural digital platform scales and one computer for centralized control. CONSTITUTION:An analog weighing signal (S) from a weighing part 2 of the digital platform scale 11 is converted into a digital weighing signal (T) with an A/D conversion part 4 and supplied to an arithmetic part 6. A tare weight signal and a target weight signal are also supplied from a ten key 8 to the arithmetic part 6. Then, when the tare and an article are mounted on a mounting stand of the weighing part 2, the signal (S) is produced and converted into the signal (T) with the conversion part 4 and supplied to the arithmetic part 6. The arithmetic part 6 substracts the tare weight signal from the signal (T) and calculates a net weight signal of the article which is displayed on a display part 10. When the signal is made stable, it is supplied to a control part 16 via a system controller 14, etc. The control part 16 accumulates the net weight signal for every digital platform scale 11-1n which is stored in a memory 22. Then, when there is a request from a personal computer 24, the control part 16 reads each accumulated value from the memory 22 and transmits it to the personal computer 24 and the arithmetic processing is performed there.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for centrally managing a plurality of digital platform scales in a factory or the like that uses a plurality of digital platform scales.

[Prior art]

Conventionally, it is well known that a plurality of electronic fare scales are centrally managed by one totalizer (see Japanese Patent Laid-Open No. 53-95070). However, this was only used for control at the point of sale at stores, etc., and there was no central control device for production and supply lines. Therefore, a printer was connected to each digital platform scale to print out the weight data, and each printout data was brought in and totaled.

[Problem that the invention seeks to solve]

However, with the above technology, a printer must be connected to each digital platform scale, resulting in high costs. Furthermore, it is troublesome to tabulate the printed data, and there is a high possibility that mistakes will be made in the tabulation.

[Failure to solve the problem]

In order to solve the above problems, the present invention provides a plurality of digital platform scales and one centralized control computer, and provides a transmission means for exchanging data between the digital platform scales and the computer. It is set up.

[Action/Effect]

According to this invention, data from a plurality of digital platform scales is transmitted to the computer via the transmission means. On the other hand, data from the computer is also supplied to each digital platform scale via a transmission means. Therefore, there is no need to connect a printer to each digital platform scale, and costs can be reduced.

Furthermore, since the tabulation and the like are automatically performed by a computer, no human effort is required, and the possibility of a tabulation error is extremely reduced.

〔Example〕

In FIG. 1, 1□ to In are digital platform scales, which are installed on various production lines in a production factory.

Since the configurations of these digital platform scales 1□ to In are all the same, the detailed configuration of only the digital platform scale 1□ will be explained. The digital platform scale 1 □ has a weighing section 2 , and an analog weighing signal from the weighing section 2 is converted into a digital weighing signal by an A/D converter 4 and supplied to a calculating section 6 . The calculation unit 6 is also supplied with a tare weight signal and a target weight signal from the numeric keypad 8. When the tare bag and the article are loaded on the platform of the weighing section 2, the weighing section 2 generates an analog weight signal corresponding to the total weight of the tare bag and the article, and this analog weight signal is transmitted to the A/ The signal is converted into a digital weight signal by the D converter 4 and supplied to the arithmetic unit 6. The calculation unit 6 subtracts the tare weight signal from this digital weight signal to calculate the net weight signal of the article. This net weight signal is displayed on the display section 10.
will be displayed.

Once stabilized, this net weight signal is supplied to the L''C control section 16 via the system controller 141 interface 20.18.
□Accumulate and total the net weight signal every 1n and store it in memory 2.
Store in 2.

Then, upon receiving a request from the personal computer 24, the control unit 16 reads each accumulated value from the memory 22, and sends the total value to the personal computer 24 via the interface 26.
Send to. The personal computer 24 performs arithmetic processing on these cumulative values.

In the above embodiment, data was only transmitted from the digital platform scale 1 to 1, but the personal computer 2
FIG. 2 shows a flowchart in which data can also be transmitted from 4 to 4. That is, a zero point command signal is supplied from the personal computer 24 to each of the digital platform scales 1□ to 1n via the system controller 14 (step A). For this reason, each digital platform scale 1□~1n
performs zero point adjustment. And each digital platform scale 1□～
When a tare is placed on 1n, each digital platform scale 1. ~1n sends the tare weight to the personal computer 24 via the system controller 14 (step B). Following this, a tare weight subtraction command signal is sent to each digital scale 1□-1n via the burner computer 24 color system condominium 14 (step C). As a result, each of the digital platform scales 1□ to 8 performs tare subtraction.

Next, each digital scale 1 is sent from the personal computer 24.
The target values are sent to □ to 1n via the system controller 14 (step D). This completes the setting of target values for each digital platform scale 1□ to rice.

Next, the objects to be weighed are loaded into each digital platform scale (step E), and the calculation section 6 determines whether the digital weight signal is greater than or equal to the target value (step F).Until this determination becomes YES, step E, The judgment in step F of repeating F is YES.
When S is reached, each digital platform scale 1□ to 1n transmits weighing data to the system controller 14 (Step G).
. The system controller 14 transfers this transmitted weighing data to each digital platform scale 1. Aggregation is performed every ~1n (Step H). Then, it is determined whether the personal computer 24 can accept the data (step I), and if YES, the total data for each digital platform scale 1□-ln is transmitted to the personal computer 24 (step J), and it is determined whether the transmission is completed (step K). ). If this judgment is NO,
Steps J and K are performed until the answer is YES, and when the answer is YES, the process returns to step A.

In each of the above embodiments, the system controller 14 performs the cumulative total, but the personal computer 24 calculates the cumulative total.
You can also do it with
