设计（论文）选题名称
基于单片机的浴缸水位水温控制系统
选题理由及准备情况：
一、 选题理由
温度控制是我们的日常生活中总会遇到的过程控制，很多的生产与生活过程都是以温度做为参考量。例如当我们正在公共的澡堂洗澡的时候，经常会突然感觉水特别的凉和热，让人难以忍受，有的人就会很难受，以后就不愿意来而且抱怨这家澡堂，因此就会有人很想想出办法来改变这个现状。温度检测和控制的准确性直接影响生产状况和产品质量。因此,在很多工业现场，我们对温度测量和精度有着相当高的要求。对于不同生产情况和工艺要求下的温度控制，所采用的加热方式、燃料、控制方案也有所不同。在现代生活中已经有了越来越多的温度控制系统，如经过红外线遥控控制温度，或者是GSM来控制温度，当温度过高，则有GSM发送短信来提示，然后短信控制风扇的转速和风力，也能够经过GSM来进行报警等等。高精度的恒温控制，能够将温度相对恒定的控制在一个值，用以满足高精度的工业要求。也有自带因子的模糊温度控制，和基于单片机的模糊温度控制系统，能够达到稳态和网络可靠性优越的功能。
二、 准备情况
一开始确定了毕业设计的思路之后，开始查找了各种温度传感器，语音芯片，89S52单片机，水位检测，液晶显示的资料，综合的进行了比较。也对现在市场上的出现的温度控制系统进行了了解，从而完善了自己的毕业设计思路，完成了自己的初步设想。采用DS18B20温度传感器测量温度，LCD12864显示温度，经过水位检测电路和温度控制电路，来达到将水位和水温控制在自己适宜的范围。
指导教师意见：
该题对现实生活的运用具有一定的可行操作性，涉及单片机多方面及本学科课程的知识内容，符合专业设计课题的悬疑要求，同意选题开题

毕业设计（论文）进行起止日期
.6.30----- .4.14
毕业设计（论文）的内容及技术参数
本次设计的主要内容有温度测量，水位检测，温度控制，语音报警，液晶显示，温度上下限的控制。温度传感器测量温度由于要测量水温，需要具备实时性和性价比，采用了DS18B20温度传感器。DS18B20温度传感器的测量温度能够从-55℃°到125℃，温度精度误差0.5℃，能够直接输出温度值，抗干扰能力也很优越，测量水温特别要注意防止液体腐蚀传感器外壳，在这点上,防水DS18b20更具优越性。
液晶显示主要是采用LCD12864，因为显示的量比较大,有当前温度；设定温度值，还要提示温度过高过低，在LCD1602或者数码管上并不能完全的实现。它的工作温度能够在-20℃到70℃，能够兼容多数的单片机，而且接口简单，操作简单方便,在显示和硬件电路上都有优势，在性价比上也有不小的领先。
语音提示是采用ISD1420芯片ISD1420芯片采用CMOS技术，，可录放实际为8至20秒，音质好。拥有边缘/电平触发两种放音控制和唯一的录音控制，电路简单。

ABSTRACT
This paper describes a single chip embedded temperature controller design programmed in a single Programmable System on Chip (PSoC);a mixed array logic consists of analog,digital and digital communication blocks within in it.The virtual instrument control program written in Labview ver.7.1,a graphical language,provides user friendly menu driven window based control panel,interacts with the single PSoC chip design for sensing and controlling the temperature.This simple cost effective embedded design finds potential application in laboratory as well as in industries.This deign can also be made as a standalone system without PC by programming LED/ LCD display and key pad attachment modules in same PSoC chip.
1. INTRODUCTION
The advent of intelligent programmable embedded silicon designs provides the ability to implement any required hardware programmatically for the design automation in industries and laboratories.Recent trend in laboratory as well as in industrial automation designs uses minimal hardware and maximum support of software.The programmable embedded components and application software available in the market enables the designer for user friendly cost effective design solution for any system automation.Temperature controllers are playing vital role in industries and laboratories.To accurately control process temperature without extensive operator involvement,a temperature control system relies upon a controller,which accepts a temperature sensor such as a thermocouple or RTD as input.It compares the actual temperature to the desired control temperature,or set point,and provides an output to a control element.The controller is one of the major parts of the entire control system,and the whole system should be analyzed in selecting the proper controller.This paper describes a novel single chip temperature controller design with Cypress Micro systems Programmable System on Chip (PSoC).Virtual instrument control program written in Lab VIEW ver.7.1 interacts with the embedded PSoC design and senses and controls the temperature of furnace / load.
2. PROGRAMMABLE SYSTEM ON CHIP (P Soc)
While Sand inexpensive interface to sensors,andmore.Cypress’System-Chip(PSoC)architecture offers a flexible,economical solution for a wide variety of applications.This paper describes the design of a temperature controller on a single CY8C27143,8 pin PSoC chip.Ass how n in fig.1,it features four main areas:PSoC core,digital system,analog system,and resources including in/out ports. This architecture allows the user to create customize Alpheratz configurations that match the requirements of each individual application.The UAR Tinter face, coupled with configurable analog and digital peripherals makes the CY8C27143 truly universal in its connections to the external world.The PSoC core includes:an M8C micro controller;32K Bytes of program flash memory;2Kbyte of data RAM;internal 24 oscillator;sleep and watchdog timer;general-purpose input/output pins (GPIO) allowing any pin to be used as digital input or output,and most pins to be used as analog inputs or outputs.Every pin can be used as a digital or analog interrupt.The digital system is made up of 8digital PSoC blocks.Each block is an 8-bit resource that can be used alone or combined with other blocks to form peripherals.Possible peripherals include:PWMs (8- to 32-bit);PWMs with dead band (8- to 24-bit);counters (8- to 32-bit);UART 8-bit with selectable parity;SPI master and slave;cyclical redundancy checker/generator (8- to 32-bit);pseudo random sequence generators (8- to 32-bit).These digital blocks can be connected to any of the GPIO through a series of global buses.These buses also allow for signal multiplexing and performing logic operations.The analog system is made up of12configurable blocks,each comp rising an op amp circuit allowing the creation of complex analog signal flows.Analog peripheral sar every flexible and can be customized to support specific application requirements.Some of the more common PS0C analog functions are:filters (2 and 4 pole band-pass,low-pass,andnotch); amplifiers (up to 2,with selectable gain to 48x);instrumentation amplifiers (1with selectable gain to 93x); comparators (up to 2, with 16 selectable thresholds);DAC (up to 2, with 6 to 10-bit resolution); and SAR ADC (up to two,with 6-bit resolution).In combination with the digital blocks,additional functions can be created, including: incremental ADCs (up to 2, with 6- to 14-bit resolution); delta sigma ADC (1,with 8-bit resolution at62.5ksps).The additional system resources provide additional capability useful for the complete system design.

3. VIRTUAL INSTRUMENT PROGRAM
Virtual instrument (VI) is an application of general purpose digital PCs for the measurement and control of various physical variables.The VI program mimics the control processes,which are in a remote area,on the PC screen.On-going process control automation can be visualized by the experimentalist through PC screen.VI program provides inexpensive and yet a powerful platform for the control and data acquisition of process variables.These programs are easy to implement with graphic languages (G-language).The “G” language implements the data flow technique.The usage of “G” language provides easy interfacing with PCs under the Windows environment [2]. The “G” language provides built-in function libraries for a variety of application requirements as graphic palettes, which in turn supports the required DLL s for the functions to run under windows environment.Usually the “G” language VI programs consist of two frames viz.,panel diagram and functional diagram.In the panel diagram,programmers can assign various controls and indicators (i.e., input and output variables).their requirements and in the functional diagram, the designers can implement the required.

4. PSoC SINGLE CHIP TEMPERATURE CONTROLLER DESIGN
Fig.2 shows the PSoC designer screen for the embedded single chip temperature controller design project [1].Left side of the screen shows the settings of global resource and user module parameters along with pin connectivity.Middle portion of the screen shows the analog and digital blocks user module placement.Top portion of the screen shows the selected user modules for this project.Right side of the screen describes the pin connectivity configured in the design.In this novel single chip design,thermocouple (TC) signal has been amplified by a programmable gain amplifier (PGA) placed in the PSoC’s analog block.The amplified TC signal has been fed in to a 12 bit Analog-to digital(ADC) user module programmed in the PSoC chip, which includes both analog and digital blocks for its functionality by PSoC designer programming.The converted digital data of the TC signal has been fed to the UART user module for serial communication with Personal Computer.The UART user module placed in the chip,automatically gets placed in two digital blocks of PSoC chip,transmitter (TxD) and receiver (RxD) for PCs serial communication.A pulse width modulator (PWM),placed in the PSoC digital block,sets a serial pulse width modulated TTL pulses in response to the PID control function for the deviation in set and measured temperature.This will in turn controls the optically coupled solid state relay (SSR) driving the AC line power connected to the load/furnace[3,4].The menu driven window based virtual instrument control program senses the temperature,via,thermocouple,TC amplifier,12-bit ADC and UART communication block of PSoC chip and evaluate the control functions like PID, linear heating, on-sweep and sets the pulse width of PWM in a PSoC chip via UART block in a serial communication.

Fig. 3 : Single PSoC chip Temperature controller design
Fig.3.shows the connectivity of a single PSoC chip design with solid state relay (SSR)and USB port via,serial-to-USB converter cable for communication with PC.The SSR,acts as AC power controller for controlling the furnace power,has been activated by the PWM pulses from PSoC chip.The menu driven virtual instrument control program works in window environment interacts with the embedded design for sensing,controlling and acquiring the temperature data. On-line plotting of acquired temperature data also carried out by the VI program.
5. CONCLUSION
A simple and cost effective embedded temperature controller has been designed,fabricated and tested successfully for its functionality.This compact designs permits the user to select any type of control function through its virtual instrument program,written in LabVIEW 7.1,and works under window environment.This design can be directly connected to PCs‘com’ port or USB port via USB-to-serial converter cable,the SSR power controller module can be connected on the furnace stand.The optically isolated power controller provides safe operation without damaging the interfacing intelligent controller.
