[系统设计方案] ds18b20

数字温度计是一种将模拟温度数据转化成数字温度数据并加以显示的系统。由传感器测得模拟温度数值,并将其转化为数字信号,通过串行通信的方法将数据传送给单片机,并由单片机处理后显示。 本设计采用ATmega16为控制部件,用1602液晶显示方式来显示所测的温度值,温度值的最小精确度为0.1℃,基本上满足一般的要求。温度传感器采用DS18B20,其传感器为数字输出,所以不需要进行模数转化直接由单片机控制读取温度值,这样大大减少了硬件的成本。 每次测温由单片机向测温传感器发出特定脉冲,测温传感器能够检测到脉冲并做相应的工作。传感器将模拟温度信号经过采集,数字处理,放大后输出。DS18B20使用一个单线接口发送或接收信息,因此在单片机和DS18B20之间只需要一条线链接,用于读写和温度转换的电源可以从数据线获得,无需外接。

[系统设计方案] HVAC

介绍了在变频制冷空调系统中为了节能和提高 COP,建立能同时独立控制室温和过热度的独立控制器设计。此研 究解决了对具有非线性性质的变频制冷空调系统的多个控制量设计独立控制器较难的问题。此控制器地设计方法不仅是用于 基本单一的制冷空调系统,也可以应用在一拖多机的系统;不仅适用于家用制冷空调系统也可以适用在多种工业用冷却系统。
Introduced in the inverter in order to refrigeration and air conditioning systems to improve energy efficiency and COP, while separate control room set up to separate moderate superheat controller design. This study addresses the frequency of non-linear nature of the refrigeration and air conditioning systems control the amount of more than one independent controller design more difficult questions. The controller design method is not only for basic single refrigeration and air conditioning systems can also be used in more than a drag machine system not only in home refrigeration and air conditioning systems can also be applied in a variety of industrial cooling systems.
