【摘要】 随着科学技术的发展,温度测量越来越受到重视,而且对测量准确度的要求也越来越高,在某些场合,温度测量问题成为关键问题。此外随着能源危机的出现,出于节能、环保的目的,在工业生产应用中,对温度的监测也越来越重要,尤其是在航天、材料、能源、冶金等领域中占有极重要地位。温度测量分为接触测温与非接触测温两大类,接触测温法测得的温度是物体的真实温度,但其动态特性差,由于要接触被测物体,故对被测物体的温度场分布有影响,而且受传感器材料耐温上限的限制,不能应用于超高温测量。非接触测温目前仍以辐射测温法为主,辐射测温在理论上不存在测温上限,具有测温范围广、响应速度快、不破坏被测对象温度场等特点。因此在实际应用中,辐射测温技术越来越受到重视并被广泛应用于高温快速测量中。本文就是利用多光谱法对导弹爆炸瞬间温度进行测量。论文详细阐述了该爆炸火焰测温系统的硬件和软件设计,硬件电路主要包括I/V转换电路,三级放大电路,采样保持电路,以及A/D转换电路和外扩存储电路。软件设计以TMS320F2812DSP为核心,由于该芯片具有低成本、低功耗、高速度,实时性好等优点,所以选择该芯片作为整个系统的核心。该系统可以测量的温度范围为800℃~3500℃,测温范围大,测量准确,性能可靠,并且由于作了相应的防爆处理使其具有一定的可更换性,因此在国防、航天、航空领域具有很好的应用前景。
硕士论文代写【Abstract】 As the development of the science and technology, people pay more and more attentions to the temperature measurement and have higher demands for accuracy. In some conditions, temperature measurement has become key problem. Besides, because of the energy crisis temperature monitoring is becoming more and more important with the purpose of energy conservation and environmental protection in the industrial production field especially in the fields of aerospace, materials, energy, metallurgy and so on.The measurement of the temperature can be divided into contacting and noncontacting one. The contacting measuring temperature gets the true temperature of the objects, however, it has poor dynamic characteristics. It will influence the temperature distribution because it has to contact the measured object and it can’t be used to measure ultrahigh temperature due to the restriction of working temperature of sensitive materials. Now radiation thermometry is the chief noncontacting measurement for that it hasn’t upper sensing limit and has the characteristics of wide temperature tested ranges, fast response, no destruction to temperature distribution and so on. So in the actual application, the technology of radiation thermometry is paid more and more attentions and being applied to high temperature rapid measurement.The paper is to measure the transient temperature of missile explosion with multi-spectral thermometry. A detailed description on the development of explosion flame temperature system of hardware and software was given. The hardware circuit mainly includes I/V conversion circuit, three-stage amplifier, sample and hold circuit, A/D convert circuit and external expanding memory. The core of the software is TMS320F2812DSP. We choose it to be the core just because it has low cost, low power, high speed and good real-time performance.The range of temperature for measurement is 800℃~3500℃, so it has large range of temperature measurement. Besides, it can implement accurate measurement and has reliable performance. Meanwhile, we have done some corresponding processing to prevent the explosion, so it has certain removability. Above all these reasons, it will have a very good application prospect in national defense, aerospace and aviation field.
