Abstract

PURPOSE:To improve operability at the time of switching sorts by receiving the sort of an object to be processed after starting collection. CONSTITUTION:In the step S21, inputted sort number data are written in a temporary storage area. During the collection of data, the sort number data stored in the sort number area are read out and whether data collection is executed prior to the input of the sort number or not is judged (S23) by judging whether the read data are null data or not. When the sort number has been inputted, whether the sort number data read out from the sort number area coincide with the inputted sort number data stored in the sort temporary storage area or not is judged (S24), and when both the data mutually different, a new storage area is prepared to input a new sort (S25). Then new sort number data written in the sort temporary storage area are written in the newly secured area (S26).

Here, the product type serial number is a temporary product type number when the product type number data is not input, and is, for example, character data that increases by 1 from 1 in order. Further, the end clear flag is a flag for determining whether or not to inherit the product at the end when, for example, one-day collection is ended and collection of the next day is started, and when this flag is "1". This means that the flag is set to the unset state, and when this flag is "0", it means that the product at the end of the previous day is succeeded. Further, the switching clear flag is a flag for setting whether the serial number automatically created internally is used as the product number data or the input product number data is used as the product number data when the product is switched by the product switching signal. Is. When this flag is "0", the product serial number is used as product number data. When this flag is "1", it is set to an unset state (null data).

The totaled results are also recorded in. [Operation] Next, the operation of the above-described embodiment will be described. The control operation of the terminal-side terminal will be described with reference to the control flowchart shown in FIGS. 6 to 8.

First, in step S1 of FIG. 6, initial setting is performed. Here, various flags are set to initial values. In step S2, it is determined whether to clear the contents of the product type temporary storage area 38. Whether to clear the temporary storage area 38 is determined by turning on / off a predetermined bit of the dip switch 29 when the power is turned on. When it is determined that the temporary storage area 38 is cleared, the process proceeds to step S3. In step S3, null data is written in the product type temporary storage area 38. This null data is data for creating a state in which the product type number data has not been set.

In step S4, it is determined whether a collection start signal is input. This judgment is made when the collection operation is controlled by the timetable, when the timetable rises to the collection state, and when the collection operation is controlled by the collection start signal from the outside,
It is performed by each rising of the acquisition start signal from the outside. If it is determined that the collection is not started, the process proceeds from step S4 to step S5. In step S5, it is determined whether or not the product type number data has been input. In step S6, it is determined whether or not the setting data has been received from the host computer 1. In step S7, another process is executed, and after execution, the process returns to step S4.

When the product type number is input, the process proceeds from step S5 to step S8. In step S8, the inputted product type number is received and a product type number input process (described later) is executed. When the setting data is received, the process proceeds from step S6 to step S9. In step S9, the contents of the setting data storage unit 27 are updated with the received setting data. As a result, the setting conditions for the terminal 4 from the host computer 1 are accepted. For example, the values of various flags stored in the flag storage area 39 of the setting data storage unit 27 are updated by the setting data transmitted from the host computer 1.

When it is determined that the collection is started, the process proceeds from step S4 to step S10. In step S10, the product serial number is set to "0". In step S11, a new storage area is secured in the data storage unit 26. That is, a new product type number storage area 35 and a new data storage area 36 are secured. In step S12, the product type number data stored in the product type temporary storage area 38 is stored in the data storage unit 2
6 in the product type number area 35. At the start of collection, the product type number data or null data at the end of collection is normally stored in the product type temporary storage area 38 depending on the content of the end clear flag, so either data is written in the product type number area 35. .

In step S13, it is determined whether a collection end signal has been input. This judgment is based on the fall of the collection state when the collection operation is controlled by the timetable, and the rise of the collection end signal when the collection operation is controlled by the collection end signal from the outside. Based on. If the collection is not completed, the process proceeds to step S14.

In step S14, a data collection operation is executed. In step S15, it is determined whether or not the product type number has been input by the operator. When the product type number is input, the process proceeds from step S15 to step S17. Step S1
In step 7, the inputted product type number data is received and a product number input process (described later) is executed. In step S16, it is determined whether a product type switching signal has been input by the operator. When the product type switching signal is input, steps S16 to S16
Go to 18. In step S18, a product type switching process (described later) is executed. Then, the process returns to step S13, and the collection operation is performed in step S14 until the end of collection is accepted.

When the collection end is accepted, the process proceeds from step S13 to step S19. In step S19, it is determined whether the end clear flag set by the host computer 1 is 1. This end clear flag is set when the collection ends and the next collection starts as described above.
This is a flag for determining whether or not to inherit the product type at the end. When the end clear flag is "1", the process proceeds to step S20, and null data is written in the product type temporary storage area 38 to bring it into the unset state. When the end clear flag is “0”, the product type temporary storage area 38
The process returns to step S4 without rewriting the contents of. As a result, when the next collection is started, the product type number data at the end is inherited.

In the product number input process of step S8 or step S17, the inputted product type number data is written in the product type temporary storage area 38 in step S21 of FIG. In step S22, it is determined whether data is being collected. This determination is made based on whether the timetable or the collection start signal is in the collection state. Note that step S
The determination is NO in the product number input process in 8, and the determination is YES in the product number input process in step S17.

If data is being collected, the process proceeds to step S23. In step S23, the current product type number area 3
The product type number data stored in 5 is read, and it is determined whether or not the data is null data. Thereby, it is determined whether or not the product type number is input prior to data collection. Here, when the product type number data stored in the product type number area 35 is null data, it means that the product type number has not been input from the collection start to the present, and when the product type number data is not null data, before data collection. Means that the product type number has been entered.

If the current product type number data is not null data (if the product type number has been input), the process proceeds to step S24. In step S24, the product type number data read from the product type number area 35 and the product type temporary storage area 3
It is determined whether the entered product type number data stored in 8 matches. If they do not match, it means that a new product type has been input, so the process proceeds to step S25,
Divide the storage area to secure a new area. In step S26, the new product type number data written in the product type temporary storage area 38 is written in the product type number area 35 of the newly secured area.

When the current product type number data is null data (when the product type number is not input), the process proceeds to step S26. As described above, the fact that the product type number data stored in the product type number area 35 is null data means that the product type number data has not been input from the start of data collection to the present. In this case, in step S26, the product type number data stored in the temporary storage area 38 after the start of data collection is stored in the product type number area. That is, the product type number is accepted after the start of data collection.

In the product type switching process of step S18 of FIG. 6, it is determined whether or not the product type switching signal has risen in step S31 of FIG. The product type switching signal is manually input by the operator each time the product type is switched. When the product type switching signal rises, the process proceeds to step S32. Step S
At 32, it is determined whether the switching clear flag is set to "1". As described above, this switching clear flag is set when the type is switched by the type switching signal.
This is a flag for setting whether or not the product serial number automatically created internally is set as the product number. When this flag is "0", the product serial number is set to the product number,
When it is "1", it is set to an unset state (null data).

When the switching clear flag is "0", the process proceeds to step S33. In step S33, "1" is added to the current product serial number. In step S34, the added product serial number is converted into character data. In step S35, the converted character data is stored in the product type temporary storage area 38. Also, the switch clear flag is "1".
In this case, the process proceeds from step S32 to step S36. In step S36, the null data is temporarily stored in the storage area 3
Write to 8.

In step S37, the data area is switched to secure a new storage area. In step S38, the null data or the product serial number stored in the product temporary storage area 38 is written in the product number area 35. Here, the product serial number is automatically written in the product number area as temporary product number data by the product switching signal. Therefore, the production management data can be handled for each product type without inputting the true product type number data. Therefore, it becomes easy to switch the product type, and the workability when switching the product type is improved. Further, when data is collected together with the product serial number in this way, after transferring the data to the host computer 1, the host computer 1 can rewrite the product serial number to true product number data. The control operation of the host-side host computer 1, shown in accordance with the control flow chart shown in FIG.

In the host computer 1, initial setting is performed in step P1 of FIG. In step P2, the operation menu is displayed. In steps P3 to P7, it is determined which process is designated from the operation menu. In Step P3, it is determined whether the online monitor process is designated. In step P4, it is determined whether the print process is designated. In step P5, it is determined whether the system settings have been designated. In step P6, it is determined whether or not another process is designated. When another process is designated, the process proceeds to step S8, and the designated process is executed.
In step P7, it is determined whether or not an end command has been issued. The process returns to step 2 until the end command is issued, and the process ends when the end command is issued.

When the online monitor process is designated, the process proceeds from step P3 to step P9. Step P9
In executes data collection display process for displaying and collecting data from each terminal 4 ₁ to 4 _N. When the printing process is designated, the process proceeds from step P4 to step P10. In Step P10, print processing is executed using various forms.
When the system setting is designated, the process moves from step P5 to step P11.

At step P11, the setting of the switching clear flag is accepted. In step P12, the setting of the end clear flag is accepted. Other settings are accepted in step P13. In the other setting process, for example, the terminal 4
Settings related to the terminal 4 such as data collection time settings of ₁ to 4 _N and settings related to this software are accepted.
In Step P14, the received setting data regarding each terminal is transmitted to the terminal 4 side. The terminal 4 receives the setting data in step S6 of FIG.
Update the contents of. [Other Embodiments] (a) The product type switching signal may be automatically input each time the product type is switched, instead of being manually input. (B) In the above embodiment, the type can be accepted before and after the start of collection, but the type may be accepted only after the start of collection.

[0038]

As described above, in the production control data collection device according to the first aspect of the present invention, the type of the object to be processed can be accepted after the start of collection, so that the operability at the time of type switching is improved. Second
In the production control data collection device according to the invention, regardless of the type acceptance, since the production control data is classified based on the acceptance of the type switching, it is possible to perform the classification according to the type without inputting the type.
