【摘要】：混凝土作为常用建筑材料,其质量问题是人们关注的焦点。混凝土是选用水泥作为胶凝材料,按照一定比例选择砂、石等固体材料作为集料,并添加水等外加剂和掺和了搅拌之后,经一系列过程而得到的建筑材料。水泥加一定量的水搅拌后,会发生化学反应,水泥中的这组成部分开始发生复杂的反应,凝结硬化成为一定强度的石状体,这个过程称为混凝土的水化热过程,水化热过程对混凝土的质量问题有着决定性的影响。为了在提高混凝土的质量,对水化热过程中对的温度进行监控是不可缺少的,通过监控系统采集到的水化热过程温度曲线,一方面指导控制部分采用一定的方法将混凝土的内外温度,内外温差,升温速度和降温速度保持在一定范围内,提高混凝土质量,一方面将通过采集到的大量数据对水化热过程与混凝土质量质检的关系进行研究,为混凝土水化热控制过程提供更完善的控制要求。国外目前已有的水化热监控设备但价格昂贵,国内设备价格较低,但大多结构简单,智能化程度不高。本课题所构建的水化热监控系统包含以Atmega128单片机为核心控制器构建下位机硬件系统,采用VC++语言开发的具有数据分析功能的上位机监控软件,同时为了采集汇总大量数据为之后的分析提供数据支持建立的远程数据服务器,构建了一套参数测定精确化、硬件结构合理化、系统智能化、数据存储能力庞大的功能完整的监控系统。
[Abstract]:As a common building material, the quality of concrete is the focus of attention. Concrete is a kind of building material obtained by selecting cement as cementing material, selecting sand, stone and other solid materials as aggregates according to a certain proportion, adding admixture such as water and mixing after mixing. When the cement is stirred with a certain amount of water, there will be a chemical reaction, and this component of the cement will begin to undergo a complex reaction, and the condensation and hardening will become stone bodies of a certain strength. This process is called the hydration heat process of the concrete. The hydration heat process has a decisive effect on the quality of concrete. In order to improve the quality of concrete, it is necessary to monitor the temperature in hydration heat process. On the one hand, guiding the control part to adopt certain methods to keep the internal and external temperature, the difference of internal and external temperature, the rate of heating up and the speed of cooling down in a certain range, so as to improve the quality of concrete. On the one hand, the relationship between the hydration heat process and the quality control of concrete will be studied through a large number of data collected, so as to provide more perfect control requirements for the hydration heat control process of concrete. The existing hydration heat monitoring equipments in foreign countries are expensive, but most of them are simple in structure and low in intelligence. The hydration heat monitoring system is composed of Atmega128 single chip microcomputer as the core controller to build the hardware system of the lower computer, and the upper computer monitoring software with data analysis function developed by VC language. At the same time, in order to collect and aggregate a large amount of data for the later analysis to provide data support for the establishment of a remote data server, a set of parameters measurement accuracy, hardware structure rationalization, system intelligence, Data storage capacity of a large function of the complete monitoring system.
