一次性環保餐具（jù）設備控製係統你了解（jiě）嗎？

一次性環保餐具設備控製係統的研發成功主要依賴（lài）於以下幾個方（fāng）麵：

The successful development of disposable environmental protection tableware equipment control system mainly depends on the following aspects:

1、需求分析比較明確。需求分析是係統開發的基礎，明確（què）的（de）需求分析是明晰業務流程（chéng）和係統功能的（de）關鍵所（suǒ）在。

1. The demand analysis is relatively clear. Requirement analysis is the basis of system development, and clear requirement analysis is the key to clarify business process and system function.

2、在設計上充（chōng）分考慮了操作簡單、維護方便和可靠性上的晑求。控製麵板設計簡（jiǎn）潔明了，PLC選型合理，資源分配設計合理（lǐ）。

2. In the design, the requirements of simple operation, convenient maintenance and reliability are fully considered. The control panel design is simple and clear, the PLC selection is reasonable, and the resource allocations design is reasonable.

3、周全考慮了成型機的內部（bù）結構和功能需求特點，采用簡單明了的硬件接線設計。

3. Considering the internal structure and functional requirements of the molding machine, simple and clear hardware wiring design is adopted.

4、在控製軟件（jiàn）的設計上，合（hé）理的選擇了（le）程序結構，采用了步進指令+高階指（zhǐ）令的程序結構、從而解決了掃描時間過長的（de）問題。

4. In the design of control software, the program structure is selected reasonably, and the program structure of step instruction and high-order instruction is adopted, so as to solve the problem of long scanning time.

接下來我們來具體了解該餐具設備控製係統的（de）各組成特點：

Next, we will specifically understand the characteristics of each component of the tableware equipment control system

一、控製麵板：

1、 Control panel:

在（zài）一次性環保餐具設備控製麵板的設計上主要（yào）考（kǎo）慮係統控製操（cāo）作的方（fāng）便，避免引起誤操作（zuò）;另外，需要考慮係統硬件接（jiē）線的方便、係統線路檢修的方便以及麵板整體的美觀。

In the design of disposable environmental protection tableware equipment control panel, the convenience of system control operation is mainly considered to avoid misoperation; In addition, we need to consider the convenience of system hardware wiring, the convenience of system circuit maintenance and the overall beauty of the panel.
                        

二、資源分配設計：

2、 Resource allocations design:

資源的分配主要涉及到輸入和輸出點的確（què）定，對應的功能（néng）按鈕以及功能的描述（shù）等，具體參見表1。為了越加清楚的（de）描述資源的分配，表中同時列出了PLC的一些內部資源的分配，包括時間繼電器和中間繼電器。

The allocations of resources mainly involves the determination of input and output points, corresponding function buttons and function description. See Table 1 for details. In order to more clearly describe the allocations of resources, the table also lists some internal resource allocations of PLC, including time relay and intermediate relay.

三、硬件線路和軟件設計（jì）：

3、 Hardware circuit and software design

硬件線路的設計比較簡單，根據資源表就可（kě）以對PLC的外部接線進行設計（jì）。軟件的（de）設計相對比較複雜，先需（xū）要繪製軟（ruǎn）件程（chéng）序流程圖，從（cóng）圖中可知，控製程序主要有3個（gè）分（fèn）支，即點動、自動和單步執（zhí）行。

The design of hardware circuit is relatively simple. According to the resource table, the external wiring of PLC can be designed. The design of the software is relatively complex. First, we need to draw the flow chart of the software program. From the chart, we can see that the control program mainly has three branches, namely inching, automatic and single step execution.

一次性環保餐具設備係統的控製（zhì）程序采用廠商提供的 PFSOFT開發工具進行（háng）開發，把 PFSOFT軟件安裝（zhuāng）在PC機上，PC機與PLC相連，打開 PFSOFT開發界麵，編寫LC控製（zhì）梯形圖程序，梯形圖（tú）程序下載到PLC中，可以在PLC上（shàng）進行模擬調試，調試平台采用（yòng）“電氣控製與PLC實（shí）驗平台開始采用常規控製指令進行編程，雖然功能上實現沒有問（wèn）題，但由於功能比較複雜，程（chéng）序比較長，以致PLC對程序的掃描時間過長，不符合（hé）成型機控製的要求。放（fàng）棄常規控製指令結構，而采用步進指令+高階指令的程（chéng）序結構，使（shǐ）得程序結構越加明晰，程序長度大大縮短，程序的（de）掃描時間達到控製的要求。

The control program of disposable environmental protection tableware equipment system is developed with pfsoft development tool provided by the manufacturer. The pfsoft software is installed on the PC, and the PC is connected with the PLC. The pfsoft development interface is opened, and the LC control ladder program is written. The ladder program is downloaded to the PLC, and the simulation debugging can be carried out on the PLC, The debugging platform adopts "electrical control and PLC", and the experimental platform begins to use conventional control instructions for programming. Although there is no problem in function realization, due to the complex function and long program, the PLC scanning time for the program is too long, which does not meet the requirements of synthetic machine control. By abandoning the conventional control instruction structure and adopting the program structure of step instruction and higher order instruction, the program structure becomes clearer, the program length is greatly shortened, and the scanning time of the program meets the control requirements.
