The two apparent intelligent controllers of the two controls of the utility model twin-tub solar water heater are to be core with the 89C52 single-chip microcomputer, cooperate 4 grades of level sensor A of two resistor-types, B, detect the hot and cold water tank respectively, one-line temperature digital temperature sensor, extended keyboard, display device, include 67 sections charactrons in the display, preceding two 7 sections charactron displays temperatures, it is temperature display watch, three, four 7 sections charactrons show water level A, be water temperature display list A, latter two 7 sections charactrons show water level B, be water temperature display list B, clock chip, driver A, B, last water solenoid valve, water solenoid valve on the cold water storage cistern, peripheral components such as electrical heating and alarm is finished the water level in the solar water heater boiler, temperature measurement, show; Level measuring and demonstration in the cold water storage cistern; Automatic loading water during lack of water, water overflow and report to the police; Manually go up water, parameter setting; Regularly water temperature is crossed functions such as low intelligent electrical heating.
89C52 is a basic product in the MCS-51 of the INTEL Corp. series monolithic, 8 single-chip microcomputers of high-performance that it adopts the reliable CHMOS technology of INTEL Corp. to make, the HCMOS product that belongs to the MCS-51 of standard, it has 32 two-way I/O mouths, wherein: P1.0 mouth control electrical heating, the P1.1 mouth is connected water solenoid valve respectively with the P1.2 mouth, water solenoid valve on the cold water storage cistern, control cold, water on the boiler, the P1.3 mouth connects alarm, P3.2-3.5 mouth and P2.0-2.3 mouth are connected hot and cold water tank's level sensor A respectively, B, digital temperature sensor connects the P3.0 serial port, other interface expansion is connected with the 8255A chip of 38 parallel-by-bit I/O mouths, is used for keyboard setting and temperature, water level shows.
Level measuring: place the position of four kinds of differing heights in the water tank respectively with 5 stainless pins, when certain draw point did not contact the water surface, it was output as high level; Output low level then when it contacts with the water surface.Their output is connected to electronic switch A, B, through electronic switch A, B oppositely and after driver A, B drive, insert the P3.0-P3.3 pin water tank 1 and P2.0-2.3 pin water tank 2 of 89C52 single-chip microcomputer respectively, after CPU judges these pins, send to and show corresponding water level value, show to be divided into 4 grades, every grade is 25% of full-water level.
Temperature measurement: the temperature-measurement principle of digital temperature sensor: it was realized by the counting clock cycle, internal counter is to the step-by-step counting of the oscillator of a temperature influence, during low temperature, the pulse of oscillator can be passed through gate circuit, and it to be a certain when high temperature is set when arriving, the pulse of oscillator can't be passed through gate circuit, counter is set to-55 ℃, simultaneously, when counter reset at current temperature value, circuit compensated the temperature coefficient of oscillator, and counter restarts counting up to returning zero, if gate circuit is not closed yet, then system repeats said process.
Clock chip: 89C52 single-chip microcomputer VCC2 connects+the 5V power supply, and VCC1 connects+the 5V reserve battery.
Keypad function: manually going up water key and electrical heating key is independent function key, water level parameter key being set and the temperature key is set is multiplexing key, when for the first time when water level parameter key is set, enter water level state is set, whenever add one, periodic duty for water level is set then by once manually going up the water key, when for the first time when the temperature key is set, enter water temperature state is set, whenever add one, periodic duty for water temperature is set then by the temperature key once is set.
Last water management circuit: water solenoid valve is controlled in the output by 89C52 single-chip microcomputer P1.1 mouth, the P1.1 mouth connects the base stage of 9013 triodes by the resistance of a 2.2K, 9013 colelctor electrode connects positive 12V power supply by a hilted broadsword relay, 9013 triode emitter groundings, when P1.1 mouth output low level, triode by, almost do not have base stage that electric current passes through triode to emitter-base bandgap grading, colelctor electrode to emitter-base bandgap grading, promptly
So the electric current that flow through relay this moment is almost 0, relay is opened; When P1.1 mouth output high level, triode 9013 conductings have bigger saturation current to flow through relay, and make its adhesive, close, thus opens solenoid valve.
The electrical heating control circuit: electrically heated relay adopts the biswitch relay, the live wire of a switch control electric heater, and another controls zero line.When 89C52 single-chip microcomputer P1.0 mouth output low level, not conducting of triode, the relay no current passes through, switch open, electric heater is not worked, when P1.0 mouth output high level, and the triode conducting, relay has big electric current to pass through, switch closure, and electric heater is started working.
The alarm control circuit: the colelctor electrode of warning output triode connects buzzer, the positive 5 volts of power supplys of another termination of buzzer, 89C52 single-chip microcomputer P1.2 mouth control warning circuit is arranged, and P1.2 mouth output high level is reported to the police when water level exceeds standard, and when not reporting to the police the P1.2 mouth is put low level.
Power circuit: for the solar energy user, the power frequency AC of the power supply of the most frequently used, most convenient yes 220V, but solar energy holds that water heater control system needs be stable+5V and+the 12V power supply, so will be the Control System Design DC power supply circuit, because the utility model is by+5V and+two different power voltage supplies of 12V, and+5V is a main power source, transformer adopts 220/8 and 220/15 transformer respectively, and mu balanced circuit adopts integrated regulator spare 7805 and 7812 to carry out voltage stabilizing respectively.
