5、方式。而传统电加热温度控制具有升温单向性、大惯性、大滞后性和时变性的特点，应用传统的模拟电路控制方法，很难达到理想的控制效果。也可能由于加热时间不能控制而产生过烧，从而浪费电能。(2）上水控制通常采用手动控制，水满不容易发觉，造成水资源的浪费。或者有所谓水位控制,是通过设定来实现太阳能热水器水箱里缺水时自动补水、水满时自动停水的功能。现有的控制方案多由水位传感器根据缺水或满水时发出的不同信号控制半导体器件的通断,从而进一步控制继电器、电磁阀的开合状态,来进行补水与否。这种方案容易造成用户在使用过程中水位下降进行补水，出现混水问题。对于家庭用户来说，一天热水的使用量相差不会很大，若使用时随时补水
6、，混水后又需要电辅热进行加。因此针对手动控制等中低端太阳能热水器，我们旨在利用水位传感器开发一种控制更加智能，而且更加经济的太阳能热水器自动上水控制系统。这套系统具有以下优点：可以自定上水时间、外部扩展能力强、使用方便、开发周期短、开发费用低。满足经济性、实用性、科学性的要求。关键词：太阳能热水器；水位传感器；自动上水控制；经济ABSTRACTIn solar thermal utilization, is widely used to produce hot water of solar energy water heater, it makes full use of the enviro
7、nmentally friendly energy sources - solar, this tense time for todays resources, has the vital significance. The solar water heater has become Chinas renewable energy market demand is one of the largest and most rapid product development. However, most of the solar energy water heater control system
8、 on the market at present is single function, complex operation, it is not convenient to control the problem, a lot of controller with functions of temperature and water level show, only and the error is bigger. The main existing problems are the following two aspects: (1) does not have temperature
9、control function. When due to weather or climate and light intensity is insufficient, the solar energy water heater will reach bath temperature requirements, to inconvenience water heater water heater users. Even if part of the solar water heater with auxiliary heating function, and is usually used
10、in electric heating mode. And traditional electric heating temperature control heating unipolarity, big inertia, big lag and time-varying characteristics, application of the traditional analog control method, it is difficult to achieve ideal control effect. May also be the result of the heating time
11、 cannot control burnt, thus wasting electricity. (2) water control usually USES the manual control, water is not easy to find, cause the waste of water resources. Or a so-called water level control, is done by setting the solar water heater tank water when the function of automatic filling water, th
12、e water is full automatic water supply. Current control scheme is much by water level sensor based on lack of water or with water of different signal control on-off of semiconductor devices, thus further control the opening and closing state of the relay, solenoid valve, or not to water. This scheme
13、 is easy to cause the loss of the user in the process of using water filling water, mix water problems. For home users, a day in the use of hot water is not a great difference, if at any time when using filling water, mix water and then need to add complementary heat. So for manual control and mid-r
14、ange solar water heater, we aim to use the control of water level sensor to develop a more intelligent, more economic and automatic water control system of the solar water heater. The system has the following advantages: you can set up time, external extension ability strong, easy to use, short deve
