PLC主要應(yīng)用的領(lǐng)域　

1．開關(guān)量邏輯控制

　　取代傳統(tǒng)的繼電器電路，實(shí)現(xiàn)邏輯控制、順序控制，既可用于單臺(tái)設(shè)備的控制，也可用于多機(jī)群控及自動(dòng)化流水線。如注塑機(jī)、印刷機(jī)、訂書機(jī)械、組合機(jī)床、磨床、包裝生產(chǎn)線、電鍍流水線等。

2．工業(yè)過程控制

　　在工業(yè)生產(chǎn)過程當(dāng)中，存在一些如溫度、壓力、流量、液位和速度等連續(xù)變化的量（即模擬量），PLC采用相應(yīng)的A/D和D/A轉(zhuǎn)換模塊及各種各樣的控制算法程序來處理模擬量，完成閉環(huán)控制。PID調(diào)節(jié)是一般閉環(huán)控制系統(tǒng)中用得較多的一種調(diào)節(jié)方法。過程控制在冶金、化工、熱處理、鍋爐控制等場(chǎng)合有非常廣泛的應(yīng)用。

3．運(yùn)動(dòng)控制

　　PLC可以用于圓周運(yùn)動(dòng)或直線運(yùn)動(dòng)的控制。一般使用專用的運(yùn)動(dòng)控制模塊，如可驅(qū)動(dòng)步進(jìn)電機(jī)或伺服電機(jī)的單軸或多軸位置控制模塊，廣泛用于各種機(jī)械、機(jī)床、機(jī)器人、電梯等場(chǎng)合。

4．?dāng)?shù)據(jù)處理

　　PLC具有數(shù)學(xué)運(yùn)算（含矩陣運(yùn)算、函數(shù)運(yùn)算、邏輯運(yùn)算）、數(shù)據(jù)傳送、數(shù)據(jù)轉(zhuǎn)換、排序、查表、位操作等功能，可以完成數(shù)據(jù)的采集、分析及處理。數(shù)據(jù)處理一般用于如造紙、冶金、食品工業(yè)中的一些大型控制系統(tǒng)。

5．通信及聯(lián)網(wǎng)

PLC通信含PLC間的通信及PLC與其它智能設(shè)備間的通信。隨著工廠自動(dòng)化網(wǎng)絡(luò)的發(fā)展，現(xiàn)在的PLC都具有通信接口，通信非常方便。

◆測(cè)試系統(tǒng)概述： ?
本系統(tǒng)主要針對(duì)各種工業(yè)、民用設(shè)備和系統(tǒng)的部件 （包括控制器、傳感器和執(zhí)行器等）進(jìn)行功能和性能 測(cè)試，采用系統(tǒng)仿真技術(shù)實(shí)現(xiàn)設(shè)備和系統(tǒng)中與被測(cè)部件 相關(guān)的其他部件的仿真與模擬功能，從而實(shí)現(xiàn)被測(cè)部件的運(yùn)行環(huán)境仿真測(cè)試。
運(yùn)行環(huán)境仿真系統(tǒng)的開發(fā)首先集中于仿真模型，精確建立一個(gè)針對(duì)機(jī)電部件和系統(tǒng)的動(dòng)態(tài)案例仿真模型庫。
這個(gè)模型庫有三個(gè)優(yōu)點(diǎn)：
·基于案例推理技術(shù)的仿真模型分類結(jié)構(gòu)：它可以 動(dòng)態(tài)調(diào)整模型數(shù)據(jù)庫結(jié)構(gòu)以滿足實(shí)際系統(tǒng)需求。
·測(cè)試仿真模型和真實(shí)系統(tǒng)匹配度的功能
·系統(tǒng)辯識(shí)工具：可以從實(shí)際的實(shí)驗(yàn)結(jié)果中提取精 確模型，并重構(gòu)動(dòng)態(tài)模型庫。
這些優(yōu)點(diǎn)可以有效地解決以前靜態(tài)模型庫帶給仿真實(shí)驗(yàn)的問題。動(dòng)態(tài)仿真模型庫具有動(dòng)態(tài)和自適應(yīng)能力， 可以滿足更廣泛的需求。運(yùn)行環(huán)境仿真系統(tǒng)以虛擬儀器 技術(shù)為基礎(chǔ)的硬件在環(huán)測(cè)試系統(tǒng)，這使仿真變得更加容易。

The main application areas of PLC

1. Switch quantity logic control

Instead of the traditional relay circuit, it can realize logic control and sequence control, which can be used for the control of a single device, and can also be used for multi-machine group control and automatic pipeline. Such as injection molding machines, printing presses, stapler machines, combined machine tools, grinding machines, packaging production lines, electroplating lines, etc.

2. Industrial process control

In the industrial production process, there are some continuous changes such as temperature, pressure, flow, liquid level and speed (that is, the analog amount), PLC uses the corresponding A/D and D/A conversion modules and a variety of control algorithms to deal with the analog amount, complete closed-loop control. PID regulation is a kind of regulation method used in general closed-loop control system. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and so on.

3. Motion control

PLC can be used to control circular or linear motion. Generally use special motion control modules, such as single-axis or multi-axis position control modules that can drive stepper motors or servo motors, widely used in various machinery, machine tools, robots, elevators and other occasions.

4. Data processing

PLC has mathematical operations (including matrix operations, function operations, logical operations), data transmission, data conversion, sorting, table lookup, bit operation and other functions, can complete the data collection, analysis and processing. Data processing is generally used in some large control systems in the paper, metallurgy, and food industries.

5. Communication and networking

PLC communication includes communication between PLC and communication between PLC and other intelligent devices. With the development of factory automation network, PLC now has a communication interface, communication is very convenient.

◆ Test system overview:
The system mainly tests the functions and performance of various industrial and civil equipment and system components (including controllers, sensors and actuators, etc.), and adopts system simulation technology to realize the simulation and simulation functions of other components related to the components under test in the equipment and system, so as to realize the simulation test of the operating environment of the components under test.
The development of the operating environment simulation system first focuses on the simulation model, and precisely establishes a dynamic case simulation model base for electromechanical components and systems.
This model library has three advantages:
Simulation model classification structure based on case-based reasoning technology: it can dynamically adjust the model database structure to meet the actual system requirements.
· Function of testing the match between simulation model and real system
· System identification tools: accurate models can be extracted from actual experimental results and dynamic model libraries can be reconstructed.
These advantages can effectively solve the problems brought by static model library to simulation experiments. The dynamic simulation model library has dynamic and adaptive capabilities to meet a wider range of needs. The operating environment simulation system is a hardware-in-the-loop test system based on virtual instrument technology, which makes the simulation easier.
