Description

A method, medium and system for on-site editing of MES work orders

technical field

The invention belongs to the technical field of automobile manufacturing, and discloses a method and system for on-site editing of MES work orders and a recording medium storing programs capable of executing the method.

Background technique

In the current auto parts production, the MES system (manufacturing enterprise production process execution system) and the data acquisition system and the PLC controlling the production site are widely used as the execution base for production process control. However, due to the failure of the MES system network or the data acquisition system network, The PLC grassroots cannot obtain production orders, resulting in production stoppages. There are two current solutions;

First, wait for the network fault at the MES system end or the network fault at the data acquisition system end to be resolved, and the data can be normally transmitted to the execution layer PLC end. In this method, the production end is in a state of waiting to stop production before the problem is finally solved, which directly leads to waste of production time, resulting in no effective output during this period, causing customers to wait and causing more serious economic losses.

Second, establish a certain amount of various types of parts inventory, and provide corresponding types of parts according to customer needs. The disadvantages: there is a risk of destocking when building too much inventory, and there is a risk of direct loss. The establishment of inventory areas leads to waste of effective use of the factory area And the risk of customer stoppage after the inventory is used up.

Contents of the invention

In view of the above problems, the present invention provides a method for on-site editing of MES work orders, which specifically includes the following steps:

S1. Cancel the upper computer work order on the PLC that controls the production site, and output the cancellation information to the MES routing communication unit;

S2. Manually edit the work order of the same model product on the PLC;

S3. Start the work order for the product of the same model, and send the data to the downstream device for execution;

S4. Store the data of the executed work order of the product of the same model on the PLC, and output the data to the MES routing communication unit.

The above solution solves the problem that the execution end of the PLC cannot receive the work order due to the network failure of the MES system or the network failure of the data acquisition system, which affects the direct synchronous delivery with the customer, and also saves the inventory caused by the establishment of a large amount of inventory. The labor cost caused by building storage, the consumption of the storage area, and the potential risk that the stock cannot be delivered after the stock is used up ensure the delivery and reduce the direct economic loss. When the network fault of the MES system is eliminated, repeated operations of the same task will not be formed, and the work order is in a traceable state.

Preferably, a modular work order template directory is established on the PLC for calling when manually editing a work order.

This saves the time of manually editing the work order each time, and facilitates the quick finding of the corresponding template from the catalog to generate the correct order.

Preferably, a comparison module is embedded in the MES system to check the difference between the canceled host computer work order and the manually edited work order of the same model product.

Compared with the data in the MES, the work order data entered manually may have errors. With the above steps, it is easy to rectify or accept it with a concession.

Another solution of the present invention is to provide a non-transitory readable recording medium for storing one or more programs including a plurality of instructions. When the instructions are executed, the processing circuit will be caused to perform the above-mentioned on-site editing of the MES work order. method.

The present invention also provides a system for on-site editing of MES work orders, including a processing circuit and a memory electrically coupled thereto, characterized in that the memory is configured to store at least one program, the program includes a plurality of instructions, the The processing circuit runs the program, and can execute the above-mentioned method for on-site editing of the MES work order.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, and the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without innovative efforts fall within the protection scope of the present invention.

As shown in the drawings of the description of the present invention, this embodiment is a method for on-site editing of MES work orders, specifically as follows:

A modular work order template directory has been established in the PLC controlling the production site. Due to the data communication failure of the upper computer, the work order of the upper computer is canceled on site, and the cancellation information is output to the routing communication unit of the MES;

Manually edit the work order of the same model product of the current customer on the PLC;

Start the work order for the product of the same model, and send the data to the downstream device for execution;

Store the data of the work order of the same model product that has been executed on the PLC, and output the data to the MES routing communication unit.

When the data communication failure of the upper computer is eliminated, the MES system will automatically obtain the work order cancellation information and manual work order data retained in the on-site PLC routing communication unit, and make adaptive task adjustments after comparison.
