恒温浴缸设计 摘要：温度是日常生活中无时不在的物理量，温度的控制在各个领域都有积极的意义。很多行业中都有大量的用电加热设备，如用于热处理的加热炉，用于融化金属的坩锅电阻炉及各种不同用途的恒温箱等，采用单片机对它们进行控制不仅具有控制方便、简单、灵活性大等特点，而且还可以大幅度提高被控温度的技术指标，从而能够大大提高产品的质量。因此，智能化温度控制技术正被广泛地采用。 本次设计以恒温浴缸设计为中心，诠释了恒温水箱控制的思路。设计中采用经典的8031单片机，配以DS18B20数字温度传感器，该温度传感器可通过键盘接口设置温度的高低值。单片机将检测到的温度信号与输入的温度进行比较，由此作出判断是否启动加热装置。另外，还加入了常用的共阳极数码管显示电路，使得整个设计更加完整，更加灵活。 关键字：恒温箱；恒温浴缸；单片机；控制 Design of Constant Temperature Bath Abstract：Temperature is the ever-present in daily life physical quantities, temperature control in various fields have positive significance. A lot of businesses have a lot of electric heating equipment, such as for heat treatment furnace for melting the metal crucible resistance furnace and a variety of different uses of the temperature boxes, using SCM to control them is not only easy to control, Simple, flexibility and other characteristics, but also can greatly improve the temperature was charged with technical indicators, which can greatly improve product quality. Therefore, intelligent temperature control technology is being widely adopted. The design of the constant temperature bath designed for adult center, a heated tank control interpretation of the idea. Design used in the classic 8031, together with the DS18B20 digital temperature sensor, the temperature sensor can be set via the keyboard interface, the temperature of the high and low values. MCU will detect the temperature of the input signal and compare the temperature, which to judge whether to start the heating device. In addition, also joined the common anode LED display circuit, making the design more complete and more flexible. 朗读 Key words：Incubators; thermostat bath; Monolithic Integrated Circuit; control显示对应的拉丁字符的拼音 字典  目录 第1章 引言 1 1.1 温度控制系统设计的背景 1 1.2 温度控制系统的发展现状及趋势 1 1.2.1 国外恒温控制的发展现状及趋势 1 1.2.2 国内恒温控制的发展现状及趋势 2 1.3 恒温浴缸设计的现状及意义 2 第2章 恒温浴缸总体方案设计 3 2.1 设计方案 3 2.1.1 温度控制方面 3 2.1.2 浴缸测温点分布方面 3 2.1.3 水循环控制方面 3 2.1.4 按摩方式方面 3 2.2 方案论证 4 2.3 系统总框图 4 第3章 恒温浴缸结构设计 5 3.1 浴缸缸体结构设计 5 3.1.1
