Abstract
A temperature intelligent controller is formed by combining an STC89C52RC single chip microcomputer with a Fuzzy Logic Toolbox design fuzzy controller with MATLAB software, uses a DS12C887 chip as a system to provide a high-accuracy clock, utilizes a DS18B20 digital temperature sensor to perform temperature measurement, controls a heating rod through a zero-crossing trigger alternating current solid-state relay so simulate an auxiliary heating function of a solar water heater, and has functions of automatically detecting the water level, automatically supplying water, displaying the temperature and heating time in real time in a liquid crystal mode, automatically giving an alarm for reminding when the set time is up and the like. The solar water heater intelligent controller can intelligently adjust power output within a set time period, enables the system to reach to the set temperature within the set time period, avoids a traditional 'rated power heating-long time heat preservation' mode, can further reduce the energy consumption and is humanized.
Description
Technical field
The present invention is a kind of Intelligent temperature controller, is exactly applied solar energy water heater intelligent controller specifically.
Background technology
Solar water heater industry development is rapid, and what present a contrast with it is that the control system of solar energy water heater matching with solar water heater is but in the research and development stage always.Mostly there is the problems such as function singleness, complicated operation, control inconvenience in the control system of solar water heater in the market, and a lot of controller modules only have temperature and level measuring and Presentation Function, and measure error is larger; And subject matter is: no matter be that solar energy directly-heated or auxiliary heating process all do not possess temp. control function.When due to weather or climate reasons and light intensity when not enough, solar water heater will not reach bathing requirement by Yin Wendu, gives to use the user of water heater to make troubles; Even and part solar water appliance has auxiliary heating function, because the electrical heating temperature control procedure of water heater has the feature of intensification one-way, large inertia, hysteresis quality and time variation, apply traditional analog circuit control method, be difficult to the control effect that reaches desirable.Some product also may be because the heat time can not burning occur Based Intelligent Control, not only wasted electric energy but also easily generation accident.In addition, what some had that the water heater of auxiliary heating function adopts is the pattern of " when rated power heats-grow be incubated ", before bringing into use hot water, user uses rated power Fast Heating, and be heated to after temperature for a long time in always in keeping warm mode, in night and non-water period still in power consumption, thereby wasted more electric energy.
Summary of the invention
The object of this invention is to provide the intelligent controller of solar heater that a kind of automaticity is high, cost is low, small and exquisite and practical.
The object of the present invention is achieved like this:
It mainly comprises: single-chip minimum system circuit, controller real-time clock interface circuit, water storage box temperature and water level detecting interface circuit, automatic watering control circuit, temperature/time are set keyboard circuit, auxiliary heating interface circuit.
Its operation principle is such:
Native system adopts STC89C52RC single-chip microcomputer, in conjunction with the Fuzzy Logic Toolbox design fuzzy controller of MATLAB software, provide high precision clock take DS12C887 chip as system, utilize DS18B20 digital temperature sensor to carry out temperature survey, control the auxiliary heating function of heating rod with analog solar water heater by zero cross fired ac solid relay; And there is automatic sensed water level, automatic loading water, the real-time displays temperature of liquid crystal and heat time, reach setting-up time can automatic alarm the function such as prompting; And can be within the time of setting adjustment power stage, make control system in setting-up time, reach design temperature, avoided traditional " rated power heating-insulation for a long time " pattern, can reduce further energy consumption, and make design have more hommization.
Its operation acts process is such:
After system powers on, single-chip microcomputer priming level trace routine, opens magnetic valve when water level lower than when setting value and adds water, until water level Self-shut electromagnetic valve while reaching setting value; Now can set the heat time, press after " determining " key, liquid crystal will show the setting value/currency of heat time and temperature, starts heating simultaneously.In heating process, single-chip microcomputer can timing sensed water level and automatic loading water, regulates the power of heater according to fuzzy rule and setup times intelligence, thereby makes water in water tank in user's setting-up time, accurately, stably arrives design temperature.
The invention has the beneficial effects as follows:
Native system components and parts used are few and system bulk is little, and lightweight, antijamming capability is strong, not high to environmental requirement.The software programming that has completed single chip part, stability is better.
Realize the automation of higher degree.
Serial communication program is also write in design host computer interface, receives in real time the temperature value of single-chip microcomputer transmission and shows curve, controls effect and makes analysis intuitively to reflect.

The specific embodiment
After system powers on, single-chip microcomputer priming level trace routine, opens magnetic valve when water level lower than when setting value and adds water, until water level Self-shut electromagnetic valve while reaching setting value; Now can set the heat time, press after " determining " key, liquid crystal will show the setting value/currency of heat time and temperature, starts heating simultaneously.In heating process, single-chip microcomputer can timing sensed water level and automatic loading water, regulates the power of heater according to fuzzy rule and setup times intelligence, thereby makes water in water tank in user's setting-up time, accurately, stably arrives design temperature.
