【摘要】：我国温室大棚采暖采用火道采暖、热风炉采暖、电热线采暖等供暖方式,火道采暖采用的是家用铁炉子和砖块砌成的炉灶,在温室大棚内安装一个向上的烟囱,依靠烟气流过烟囱进行热交换,从而对温室大棚进行供热,这种采暖方式管理不便,填煤频繁、容易造成火灾,温室大棚内污染严重。热风炉采暖所用能源不同,可分为燃煤热风炉、燃油热风炉及热气热风炉等,但是燃油设备虽然造价比较低、占地面积比较小,土建资源也低,但是运行费用比较高,相同的比热值要比燃煤费用高3倍。电热线采暖依靠电热线放出热量来提高地温,电热线采暖方式通常是用来育苗,但是电线埋在地下容易造成老化损害,同时消耗大量电费,使用成本较高。根据我国现阶段温室大棚供热设备发展情况,需要解决温室大棚有效、节能、经济已经波仔眉睫。现在国家一直在倡导节能减排,采用绿色能源和节约型能源。根据我国目前的基本国情以及用户市场的需求这一现象急需改善。基于上述研究背景,本文设计出一款自身能够进行发电,并可以自供电给水流,使其产生温度进行供热。这样既能够节约能源、保护自然环境;也可以降低温室大棚的经济成本。能够很好的对温室大棚进行供热。本文设计了一款基于单片机Mega128及水流发电机设计一款自发电式的热量测量仪。热量计量表依据的是温度、压力、流量、热量四个参数。本文首先提出基本的设计要求,同时对方案进行论证和比较,根据最终方案,进行了系统供电单元硬件系统设计。单片机及其外围电路、系统实现及程序设计等。论文的最后对设计的系统进行了测试及分析,使其最终能够根据需要调节室温,保证室内温暖舒适,并且计量方便,达到节能的目的。
[Abstract]:The greenhouse greenhouse in our country adopts the heating methods such as fire way heating, hot blast stove heating, electric hot wire heating and so on. The fire tunnel heating adopts the stove made of home iron stove and brick, and installs an upward chimney in the greenhouse shed. Rely on flue gas flow through the chimney for heat exchange, thus heating greenhouse, this heating mode is inconvenient, coal filling frequent, easy to cause fire. The pollution in greenhouse is serious. The heating energy of hot-blast stove is different. It can be divided into coal-fired hot stove, oil-fired hot stove and hot-air stove, etc., but the cost of fuel equipment is relatively low, and the area of land is relatively small. Civil engineering resources are also low, but the operating cost is relatively high, the same specific calorific value is three times higher than the cost of coal burning. The electric hotline heating relies on the electric hotline to release heat to improve the ground temperature, and the electric hotline heating method is usually used to raise seedlings. But the electric wire buried in the ground will easily cause aging damage, at the same time consume a large amount of electricity, use high cost. According to the current situation of greenhouse heating equipment in China, it is necessary to solve the greenhouse greenhouse effective, energy-saving. The economy has become a bogey. Now the country has been advocating energy conservation and emission reduction. Using green energy and energy-saving energy, according to the current situation of our country and the demand of user market, this phenomenon needs to be improved. Based on the above research background, this paper designs a kind of power generation. And it can supply water flow by itself, make it produce temperature for heating, which can save energy and protect the natural environment. It can also reduce the economic cost of greenhouse. It can heat the greenhouse well. This paper designs a heat measuring instrument based on single-chip microcomputer Mega128 and hydrogenerator. The calorimeter is based on temperature. Pressure, flow, heat four parameters. This paper first put forward the basic design requirements, at the same time to demonstrate and compare the scheme, according to the final plan. The hardware system design of the system power supply unit, single chip microcomputer and its peripheral circuits, system implementation and program design, etc. At the end of the paper, the system is tested and analyzed. Finally, it can adjust the room temperature according to the need, ensure the indoor warmth and comfort, and measure conveniently, achieve the purpose of energy saving.
