qt rcc 原理

qt rcc 原理摘要：1.QT RCC 简介2.QT RCC 的工作原理3.QT RCC 的应用领域正文：1.QT RCC 简介QT RCC，全称Qt 远程控制中心，是一款基于Qt 框架开发的远程控制软件。

它主要用于实现对嵌入式设备的远程监控、控制和管理，通过串口、以太网等网络方式与设备进行通信，为用户提供实时的数据展示和设备操控功能。

QT RCC 具有操作简单、界面友好、功能强大等特点，广泛应用于工业自动化、智能家居、医疗设备等领域。

2.QT RCC 的工作原理QT RCC 的工作原理可以分为三个部分：客户端、服务器端和嵌入式设备。

（1）客户端：客户端是用户使用的部分，主要负责与服务器端建立连接，接收服务器端发送的数据，并将这些数据以图形化界面的形式展示给用户。

同时，客户端也可以接收用户的操作指令，并将这些指令发送给服务器端。

（2）服务器端：服务器端负责处理客户端的请求，对接嵌入式设备的数据，并将这些数据发送给客户端。

当客户端发送操作指令时，服务器端会将这些指令转发给嵌入式设备，并根据设备的响应结果返回给客户端。

（3）嵌入式设备：嵌入式设备是QT RCC 控制的对象，负责处理服务器端发送的指令，并将设备的数据上传给服务器端。

嵌入式设备通常具有串口、以太网等网络接口，可以与服务器端进行通信。

3.QT RCC 的应用领域QT RCC 广泛应用于各种远程监控和控制场景，主要包括以下几个领域：（1）工业自动化：QT RCC 可以用于实现对工业设备的远程监控和控制，提高生产效率和设备维护的便捷性。

（2）智能家居：QT RCC 可以用于实现对家居设备的远程控制，如控制家电、照明等，为用户提供智能化的生活体验。

（3）医疗设备：QT RCC 可以用于实现对医疗设备的远程监控和管理，提高医疗服务的效率和质量。

（4）交通运输：QT RCC 可以用于实现对交通运输设备的远程监控和控制，如无人驾驶、无人机等，提高交通运输的安全性和效率。

基于CAN总线的远程数据

CAN总线作为一种有效支持分布式控制和实时控制的技术，以其稳定性好、可靠性高、抗干扰能力强、通讯速率高、维护成本低及其独特的设计越来越受到人们的重视，并被公认为是最有前途的现场总线之一。

基于CAN总线的远程数据采集系统分为上位机、CAN总线和下位机三个部分。

上位机建立友好的人机交互界面；CAN总线采用总线型拓扑结构，通信电缆采用双绞线；下位机部分是两个传感器节点。

本论文重点介绍了下位机传感器节点的设计。

首先介绍了系统总体设计方案，然后对温度传感器节点使用的K型热电偶、温度传感器AD590和压力传感器节点使用的MPX53DP做简要介绍，并分析设计放大电路；接着介绍单片机AT89C52及其附属电路，特别对键盘做了重点分析介绍；分析软件算法，使用C51语言编程；最后介绍系统调试。

本设计实现了下位机对现场温度信号和压力信号的采集，通过键盘在线更改测量范围、报警值等参数。

CAN bus has some advantages such as high level of security,strong anti-interference, high communication speed and low of maintenance cost. It is a particular design, and it is regarded a field-bus with expansibility.The long-distance data collection based on CAN bus is divided into three parts: upper computer and CAN bus and lower computer. The upper computer is established friendly Human-Machine Interface.CAN bus uses bus topology structure, and use UTP cable communications. The lower computer uses two sensor nodes.This paper’s emphasis is to introduce the design of the lower computer sensor node.This design firstly introduced the system overall project design. It introduced briefly the K-thermocouple which uses temperature sensor node, and the MPX53DP which uses temperature sensor AD590 and pressure sensor node.It analyzed the design enlargement electric circuit. It also introduced AT89C52 MCU and its subsidiary circuit, especially focused on analyzing the keyboard.Then it analyzed software algorithm, and used the C51 language for its programming. It introduced the system debugging finally. This design has realized the lower computer to the scene temperature signal and pressure signal collection; through the keyboard it can change online measurement range and alarms and so on.Key words: CAN bus; data collection; lower computer; AT89C52 MCU目录摘要 (I)Abstract (II)第一章基于CAN总线的远程数据采集系统总体方案 (1)1.1 研究背景 (1)1.2 方案的选择 (1)1.2.1数据采集分析 (1)1.2.2 现场总线概述 (2)1.2.3 CAN总线 (3)1.3系统设计方案 (4)第二章温度传感器节点 (7)2.1 热电偶及其放大电路 (7)2.1.1 热电偶测温原理 (7)2.1.2 热电偶的种类及结构形成 (8)2.1.3 热电偶的选择及其放大电路 (9)2.2 热电偶的冷端温度补偿 (11)2.2.1热电偶的冷端温度补偿方法 (11)2.2.2 AD590及其放大电路 (12)第三章压力传感器节点 (15)3.1压力传感器及其测温原理 (15)3.2 放大电路 (16)第四章单片机数据处理模块 (18)4.1 芯片选择 (18)4.1.1单片机的选择 (18)4.1.2 A/D芯片的选择 (18)4.1.3看门狗选择 (18)4.2硬件电路连接 (19)4.3 显示方式 (20)4.4 键盘 (22)4.4.1 键盘接口技术 (22)4.4.2 键盘设置 (22)4.5看门狗及复位电路 (24)第五章软件编程 (26)5.1 软件编程概述 (26)5.2 温度传感器节点软件设计 (26)5.3 压力传感器节点软件设计 (36)5.4 编程心得 (42)第六章系统调试 (44)6.1下位机节点调试 (44)6.1.1 模拟放大电路调试 (44)6.1.2 显示电路调试 (45)6.1.3 单片机模块调试 (45)6.1.4 键盘调试 (46)6.2 综合调试 (46)6.3 设计结果 (47)参考文献 (48)附录A 基于CAN总线的远程数据采集系统硬件原理图 (49)附录B 温度传感器节点硬件原理图 (50)附录C 压力传感器节点硬件原理图 (51)附录D 下位机C51程序清单 (52)致谢 (93)第一章基于CAN总线的远程数据采集系统总体方案1.1 研究背景随着现代工业技术的发展，特别是计算机、控制、网络通信技术在工业中各个具体行业的广泛应用，促进了计算机、控制、网络通讯技术的发展，同时这些技术又与各个行业中的其它技术融合，促进了各个行业的飞速发展[1]。

rcc 反馈展宽电路

rcc 反馈展宽电路English Answer:RCC (Reinforced Cement Concrete) feedback is a technique used to analyze and optimize the design of reinforced concrete elements. It involves iteratively adjusting the design variables, such as the amount of reinforcement and the concrete cover, to meet specific performance criteria.There are two main types of RCC feedback:Positive feedback: The design variables are adjusted in a way that amplifies the desired effect. For example, increasing the amount of reinforcement will increase the strength of the element.Negative feedback: The design variables are adjusted in a way that dampens the undesired effect. For example, increasing the concrete cover will reduce the risk ofcorrosion of the reinforcement.RCC feedback can be used to improve the performance of reinforced concrete elements in a number of ways, including:Increasing strength: By increasing the amount of reinforcement and the concrete cover, the strength of the element can be increased.Reducing deflection: By increasing the amount of reinforcement and the concrete cover, the deflection of the element can be reduced.Improving durability: By increasing the concrete cover, the risk of corrosion of the reinforcement can be reduced.Reducing cost: By optimizing the design of the element, the cost of the element can be reduced.RCC feedback is a powerful tool that can be used to improve the performance of reinforced concrete elements. It is a valuable technique for structural engineers to use inthe design of reinforced concrete structures.中文回答：RCC 反馈。

RCC开关电源变压器设计方法及步骤

RCC开关电源变压器设计方法及步骤
RCC(RINGING CHOKE CONVERTER)是一种非定频电源.在RCC 设
计中,一般先设定工作频率,如为50K,然后设定工作DUTY 在90V 入力,最大输
出时为0.5
假设设计一功率为12V/1A
1. 最大输出电流为定格电流的1.2~1.4 倍,取1.3 倍.
2. 出力电力Pout = Vout × Iout = 12V×1.3A = 15.6W
3. 入力电力Pin = Pout/∩=22.3W(RCC效率∩一般设在65%~75% , 取70%)
4. 入力平均电流Iin=Pin/Vdc(INmin)=22.3/85*1.2=0.22( Vin(DCmin) = Vac(Inmin)×1.2)
5. T=1/SwF=1/50K=20uS Ton=Toff=10uS
6. Ipk=Iin 入力平均电流*2/DUTY=0.22*2/0.5=0.88
7. 一次侧电感量Lp=Vin(DCmin)*Ton/Ipk=102*10/0.88=1159uH 取1160uH
8. 选择磁芯,根据磁芯规格,选择EI28. Ae=0.85CM 动作磁通=2000~2800
取2000(当然,这是很保守的作法)
9. Np=Ipk*Lp*K/Ae*▲Bm=(0.88*1160*100)/(0.85*2000)=60Ts
10. Ns=(Vout+Vf)*Np/Vin(DCmin)=7.6 取8Ts
11. 辅助电压取5V(晶体管) 如功率管使用MOSFET 则应设为11V
12. Vin(DCmin)/Np=Vb/Nb----Nb=2.94 取3Ts
故变压器的构造如下:
Lp=1160uH。
