Abstract

PURPOSE:To make it possible to change and add production steps, by writing the address of the next step when the production step is changed in a next-step address-information area, and using the addresses for the new step, change in step sequence and the like. CONSTITUTION:An address control device 3 outputs an address signal AD, which specifies the address of the initial production step in the preset production process, and reads the address information of the next step of said specified address. When a next-step specifying signal NX is inputted and the already written address information of the next step is at the initial state of a memory medium, the addresses in the sequence of the preset steps are specified. When the address is the specific address, an address signal, which specifies the specific address, is outputted. Then, the address information of the next step is updated to the address information of the next step in the address specified by said address signal AD. Then, the change in step sequence and addition of the production steps can be performed by writing in the address-information area of the associated next step and writing in the information area of the unit step in the new production step. The change in step sequence and the addition of the production steps can be readily performed in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a production process management method for processing and managing production processes in a predetermined order.

[Conventional technology]

Conventionally, in this type of production process management system, as shown in FIG. 4, the process order of a plurality of production processes is set in advance, and the process name 14 of each of these production processes is stored in a storage device using a PROM device or the like. The process name area 11 of the corresponding address 31 is written in process order, and the process name 14 is written in the order of this address 31.
The configuration was such that each production process was read out and sequentially processed. When the processing of the production process is completed, the passage sign "Opa" is written in the passage sign area 13 provided corresponding to each production process.

[Problem that the invention seeks to solve]

In the conventional production process management method described above, the process names 14 of a plurality of production processes are written in the process name area 11 of the corresponding address 31 of the storage device in a preset order, and these are sequentially read out and processed. Therefore, when changes or additions occur to the production process, it is not possible to partially rewrite the memory contents, and it is necessary to erase all the stored contents and rewrite them all again. However, it has the disadvantage that it takes time to rewrite it.

For example, a 64 to 4.800 bit EERPOM device
Assume that reading, writing, and verification after writing are performed via a bit/second communication line, that is, it takes 40 seconds.

An object of the present invention is to provide a production process management system that allows changes and additions to the production process by only changing the relevant parts of the storage device, and allows changes and additions to the production process to be made easily and in a short time. be.

A central controller that reads information from the process information area, outputs an operation instruction signal to operate the production process with the process name included in this information, and outputs a next process instruction signal when the operation of this production process is completed. , when the reset signal is input, the address signal designating the address of the first production process set in advance is outputted, and next process address information of this address is read, and when the next process instruction signal is input, the address signal is read. When the stored next process address information is in the initial state, an address in the preset address order is specified, and when it is the specific address, the address signal that specifies this specific address is output, and the next process address information of this address is output. and an address control device that updates the read next process address information, and normally writes each process name in a preset process order in the process name area of each address in the address order, and updates the next process address information. The address information area is left in the initial state, and when a change in the process order occurs, the specific address of the next process address is written in the related next process address information area, and the production process is added. At this time, the unit process information area is secured at a new address, and the process name of this production process is written and the specific address is written in the next process address information area of the related address.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The storage device 1 includes a process name area in which the process name of each production process is written in a predetermined address corresponding to a plurality of production processes;
A unit process information area that has a next process address information area in which the initial state of the storage medium or a specific address is written as address information for the next process, and a passing sign area in which to write whether the processing of this production process has been completed. is provided.

The central control device 2 outputs a reset signal R3 at the start of operation, and when the address signal AD is input, it reads information from the unit process information area of the address of the storage device 1 specified by this address signal AD, and reads the information contained in this information. It outputs an operation instruction signal PD for operating the production process with the process name. When the operation and processing of this production process are completed, the next process instruction signal NX is outputted, and information of the passing sign "0" is outputted.

When the reset signal R3 is input, the address control device 3 outputs an address signal AD specifying the address of the first production process of the preset production processes, reads the next process address information of this address, and instructs the next process. When signal NX is input, the next process address information that has already been read is the initial state of the storage medium! When it is a specific address, it specifies an address in a preset process order, and when it is a specific address, it outputs an address signal that specifies the specific address.

Then, the next process address information that has already been read is updated to the next process address information of the address specified by this address signal AD.

Address bus 4 and data bus 5 transmit addresses and information between storage device 1, central control device 2, and address control device 3, respectively.

FIG. 2 is a schematic diagram showing an example of the configuration and stored information of each unit process information area 10 provided in the storage device l.

The unit process information area 10 is composed of a process name area 11, a next process address information area 12, and a passing sign area 13, and the process name area 11 stores process names 14 in a preset process order in the order of 31 addresses. ing.

Further, in the next process address information area 12, the address information of the next process is stored in the initial state of the storage medium, that is, "'FF
” or a specific address. Usually the second
As shown in the figure, all address information 15a is "FF". When a change in the process order occurs, a specific address indicating the address of the next process is written in the related next process address information area 12, and when a production process is added, the new address is written in the unit process information area 10 of the production process. is secured and the process name 14 is written, and a specific address is also written in the next process address information area 12 of the related address.

Figure 3 shows each unit process information 1 when a production process is added.
FIG. 2 is a schematic diagram showing the contents of 0.

This example is a case where the production process [Rinse J] is added after "Water washing" at address "00'".

In this case, the next process address information area 12 at the address "00゛°" contains the specific address "90 '" of the new address.
is written. Therefore, after the "washing" process of the address control device is completed, the address is set to 90 degrees as shown by arrow A.
“Proceed to the “rinsing” process. Also, the address "' 9
A specific address ``10°'' is stored in the next process address information area 12 of 0'', and after processing the ``rinsing'' process, the process moves to the address ``10'' as shown by arrow B.
After this, since the address information for each next step is "F F ", the steps are processed in the order of the addresses.

Therefore, changing the process order or adding a production process can be done by writing to the related next process address information area 12 and writing to the unit process information area of the new production process, making it easy to change the process order or add a production process in a short time. Additions can be made. In addition,
Changes in the production process of the pond, such as deletion, process changes, etc.
The same thing can be done by changing the order of the steps mentioned above and adding production steps.

In this embodiment, for example, when adding 100 bytes of information over a 4,800 bit/second communication line, it can be done in 0.5 seconds.

[Effects of the Invention] As explained above, the present invention normally leaves the next process address information area in the initial state of the storage medium, and when a change in the production process occurs, writes the address of the next process and updates it. Change the production process by changing the configuration used to change the process or process order.

This has the effect of allowing additions to be made easily in a short period of time.

In addition, especially in production process systems that use IC cards and the like that store highly sophisticated information, there is also the advantage that other valuable data collected can be used without being erased.
