【摘要】：本文研究的是一套較完善的空氣壓縮機聯(lián)控系統(tǒng)。空氣壓縮機作為工業(yè)生產(chǎn)過程中的一種動力輸出設(shè)備,普遍應(yīng)用于各種生產(chǎn)環(huán)境。目前多數(shù)生產(chǎn)環(huán)境對空壓機輸出氣壓的穩(wěn)定性,準確性和實時性要求并不高。然而隨著現(xiàn)代工業(yè)生產(chǎn)精細化管理,許多工廠對空壓機系統(tǒng)要求越來越高。為提高生產(chǎn)線氣壓控制的高精度,低能耗,迅速響應(yīng)等要求,該系統(tǒng)應(yīng)運而生。 該系統(tǒng)設(shè)計以項目要求為依據(jù),通過結(jié)構(gòu)化建模處理,將整個控制系統(tǒng)按功能劃分為：輸入輸出模塊,空壓機控制模塊,順序切換模塊,通訊模塊,分氣缸PID調(diào)節(jié)模塊和報警模塊。為便于用戶操作管理,該系統(tǒng)的人機交互界面使用Wincc開發(fā),可在Windows系統(tǒng)上穩(wěn)定運行。使用該HMI(人機交互界面)可以遠程控制系統(tǒng)管轄的各種設(shè)備,較之手工抄表的傳統(tǒng)工作方式更加安全高效。系統(tǒng)還具備歷史查詢功能和趨勢分析功能,為生產(chǎn)分析,流程管理提供了有效的分析手段。系統(tǒng)設(shè)計中有以下三點重點工作： 1.將軟件工程中的結(jié)構(gòu)化編程思路應(yīng)用于PLC項目開發(fā),在項目過程中體現(xiàn)出諸多優(yōu)勢。如程序結(jié)構(gòu)簡明清晰,便于程序修改和系統(tǒng)調(diào)試,為項目后期的收尾工作節(jié)約了大量時間等。 2. Modbus輪詢法控制數(shù)據(jù)通訊。該方法在通訊收到干擾的情況下,較傳統(tǒng)的時序法通訊更為高效穩(wěn)定。提高數(shù)據(jù)讀寫的穩(wěn)定性和可靠性,為整個系統(tǒng)奠定了良好的通信基礎(chǔ)。 3.使用面向?qū)ο蟮木幊趟悸烽_發(fā)空壓機控制模塊。提高該模塊的擴展性和通用性,從而提高整個系統(tǒng)的擴展性和可維護性,為系統(tǒng)升級和二次開發(fā)提供便利。 該系統(tǒng)實施后在不影響實際工作需求的情況下降低供氣管網(wǎng)壓力,節(jié)能降耗；減少空壓機工作時間,并且可以通過調(diào)整不同機器的工作狀態(tài)平衡各機器的工作損耗；為工廠的設(shè)備維護檢修,升級換代提供方便。通過自動化程序控制空壓機工作,減少了人員操作失誤的幾率,提高了控制的實時性和準確性,有利于工廠的智能生產(chǎn)管理。
[Abstract]:This paper studies a set of air compressor control system. As a kind of power output equipment in industrial production, air compressor is widely used in various production environments. At present, the stability, accuracy and real-time of air compressor output pressure are not high in most production environments. However, with the fine management of modern industrial production, many factories are demanding more and more air compressor system. In order to improve the high precision, low energy consumption and rapid response of air pressure control in production line, the system emerges as the times require. The design of the system is based on the project requirements. Through structured modeling, the whole control system is divided into input and output module, air compressor control module, sequential switching module and communication module. Separate cylinder PID regulation module and alarm module. In order to facilitate user operation and management, the man-machine interface of the system is developed with Wincc and can run stably on the Windows system. The HMI (man-machine interface) can be used to remotely control all kinds of devices under the control of the system, which is more safe and efficient than the traditional manual meter reading. The system also has historical query function and trend analysis function, which provides an effective analysis method for production analysis and process management. The system design has the following three key tasks: 1. The structural programming idea in software engineering is applied to the development of PLC project, which shows many advantages in the process of the project. Such as simple and clear program structure, easy to modify the program and system debugging, for the end of the project to save a lot of time. 2. Modbus polling method controls data communication. This method is more efficient and stable than the traditional sequential method when the communication is disturbed. Improve the stability and reliability of data reading and writing, and lay a good communication foundation for the whole system. 3. The control module of air compressor is developed by object-oriented programming. The extensibility and generality of the module are improved, and the extensibility and maintainability of the whole system are improved. It is convenient for system upgrade and secondary development. The system can reduce the pressure of gas supply network, save energy and reduce consumption, reduce the working time of air compressor, and balance the working loss of each machine by adjusting the working state of different machines. For the factory equipment maintenance and repair, upgrade to provide convenience. The work of air compressor is controlled by automatic program, which reduces the probability of personnel operation error, improves the real-time and accuracy of control, and is beneficial to the intelligent production management of the factory.
