你了解一次性環保餐具設備控製（zhì）係統嗎?

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

　　1.需求分析相對清晰。需求分析是係統開發的基礎，明確的需求分析是明確業務流程和（hé）係統功能（néng）的（de）關鍵。

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

　　2.在設計上充分考慮了操作簡單、維修方便和可靠性晑請求。控製麵板設計簡單明了，PLC選（xuǎn）擇合理，資源（yuán）分配設計合理。

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

　　3.充分考慮注塑機內部結構和功能要求，采用簡（jiǎn）單清晰的硬件布線設計。

　　3. Fully consider the internal structure and functional requirements of the injection molding machine, and adopt simple and clear hardware wiring design.

　　4.在控製軟件設計中，合理選擇程序結（jié）構，采用指令步進+高階（jiē）指令程序結構，解決了掃描時間過長的問題。

　　4. In the design of control software, the program structure is selected reasonably, and the problem of too long scanning time is solved by using the instruction step + high order instruction program structure.

　　下麵（miàn）我們詳細了（le）解一下（xià）餐具（jù）設備控（kòng）製係統的組成部分:

　　Now let's have a detailed understanding of the components of the tableware equipment control system:

　　即控製麵板:

　　I.e. control panel:

　　1.一次性餐具設備控製麵板的設計（jì）主要考慮係統控製操作（zuò）的便利性，避免誤操作;此外，還需要考慮係統硬件（jiàn）布線的便利性、係統（tǒng）線路維護以及麵板的整體美觀性。

　　1. The design of the control panel of disposable tableware equipment mainly considers the convenience of system control operation to avoid misoperation; in addition, the convenience of system hardware wiring, system circuit maintenance and the overall aesthetics of the panel need to be considered.

　　2.資源配置設（shè）計

　　2. Resource allocations design

　　資源分配主要包括輸入輸（shū）出點的確定，相應的功能按鈕，功能描（miáo）述等。詳見表1。為了更清楚地描述資源分配，該表還列（liè）出了（le）PLC內部的一些（xiē）資（zī）源分配，包括時間繼電器和中間繼電器。

　　Resource allocations mainly includes the determination of input and output points, corresponding function buttons, function descriptions, etc. See Table 1 for details. In order to describe resource allocations more clearly, the table also lists some resource allocations within PLC, including time relay and intermediate relay.

　　3.硬件電路及（jí）軟件設計

　　3. Hardware circuit and software design

　　硬件電路設計相對簡單，可以根據資源表對（duì）PLC進行外部布線設計。軟件設計相對複雜（zá），有必要繪製軟件程序流程圖。從（cóng）圖中可以看出，控（kòng）製程序主要有點動、自動和單步執行三個分支。

　　The design of hardware circuit is relatively simple, and the external wiring of PLC can be designed according to the resource table. The software design is relatively complex, so it is necessary to draw software program flow chart. As can be seen from the figure, the control program mainly has three branches: inching, automatic and single step execution.

　　一次（cì）性環保餐具設備係（xì）統控製程序使用供應商PFSOFT開發工（gōng）具開發,PFSOFT軟件安裝在PC, PC和PLC相連,打開PFSOFT開發接（jiē）口,編寫LC控製梯形圖程序下載（zǎi）到PLC梯形圖程序,可以模擬在PLC調試,調試平台采用“電氣（qì）控（kòng）製（zhì）與PLC實驗平台開始采用傳統編（biān）程控製指令,雖然在功能上沒有問題，但是功能比較複雜，程序比較長，使得PLC對程序的掃描時間太長，不（bú）滿足成型機控製的要求。摒棄了傳統的控製指令結構，采用步進指令+高階（jiē）指令的程序結構，使（shǐ）程序結構更加清晰，程序長度大大縮短，程序的掃（sǎo）描時間滿足控製要求。

　　The control program of disposable environmental protection tableware equipment system is developed by pfsoft development tool of the supplier. Pfsoft software is installed in PC, PC and PLC are connected, pfsoft development interface is opened, LC control ladder program is compiled and downloaded to PLC ladder program, which can simulate debugging in PLC. The debugging platform adopts "electrical control and PLC experimental platform start to use traditional programming control instructions, Although there is no problem in function, but the function is complex and the program is long, which makes PLC scan the program too long and does not meet the requirements of molding machine control. The traditional control instruction structure is abandoned, and the program structure of step instruction + higher-order instruction is adopted to make the program structure clearer, the program length greatly shortened, and the scanning time of the program meets the control requirements.
