【摘要】：介绍了动态辐射扫描测温仪相应的硬件和软件设计。硬件设计主要是两部分:光学设计和电路设计。光学设计主要包括光学镜头、扫描镜、激光器、透镜组以及孔径光栏这五部分。电路设计由前置放大电路和数据处理电路组成。前置放大电路包括前置放大器AD820、反相放大器OP07以及继电器三个部分;数据处理电路采用STC12C5A16S2单片机最小系统,通讯采用MAX232进行;并且将12864k12作为液晶显示屏;其中,运用矩阵键盘,按键的功能包括发射率的设定、扫描频率的设定、测量键、通讯键和复位键,并且采用AC/DC的电源模块。动态辐射扫描测温仪采用非接触法测量,这种测量方法的主要优点是测量精度高、响应速度快、测试方便、便于携带等,使得该测量仪能够在危险系数高、辐射强度大、具有腐蚀性等恶劣环境下进行测量,使用方便,因此在市场中有着广阔的应用前景。
[Abstract]:This paper introduces the hardware and software design of dynamic radiation scanning thermometer. The hardware design is mainly composed of two parts: optical design and circuit design. Optical design mainly includes optical lens, scanning mirror, laser. The circuit is composed of preamplifier circuit and data processing circuit. The preamplifier circuit consists of three parts: preamplifier AD820, inverse amplifier OP07 and relay. The data processing circuit adopts the STC12C5A16S2 microcontroller minimum system, the communication adopts MAX232, and takes 12864k12 as the liquid crystal display screen, in which, uses the matrix keyboard, the key function includes the emissivity setting, the scanning frequency setting, the measuring key. The communication key and reset key are used, and the power module of AC/DC is used. The dynamic radiation scanning thermometer is measured by non-contact method. The main advantages of this method are high measuring precision, fast response speed, convenient test, easy to carry, etc. The instrument can be used in the environment of high risk coefficient, high radiation intensity, corrosive and so on, and it is convenient to use, so it has a broad application prospect in the market.
