Detailed description of the invention
As a kind of preferred version, STM32 selected by controller described in the utility model, and this chip internal is integrated with ADC acquisition function block.
Below in conjunction with accompanying drawing, the utility model is further described.
The theory diagram of the radon chamber constant temperature and humidity automaton that Fig. 1 provides for the utility model, it comprises temperature detecting module, humidity detecting module, controller, humidity control system, humidity control system and display module.Described temperature detecting module gathers port primarily of the ADC of temperature sensor, signal amplification circuit and STM32 and forms; Humidity detecting module gathers port primarily of the ADC of humidity sensor, signal amplification circuit and STM32 and forms; Humidity control system comprises compressor, condenser, evaporimeter, capillary, fan, circulating line composition; Humidity control system is made up of dehumidifier, humidifier, fan, circulating line; Display module is made up of LCD display and LED.
Fig. 2 is the temperature Principles of Regulation block diagram of the utility model radon chamber constant temperature and humidity automaton, temperature Principles of Regulation and conventional air-condition principle similar, by the gaseous state of compressor by the gaseous refrigerant boil down to HTHP of low-temp low-pressure, then condenser (radon chamber is outer) is delivered to, due to the reduction of pressure and temperature, refrigerant gas is condensed into liquid, and the amount of heat that sheds, and what the fan of condenser was produced by boasting is exactly hot blast; Then evaporimeter is entered by capillary; Suddenly increase because cold-producing medium arrives evaporimeter (radon chamber in) rear space from capillary, pressure reduces, refrigerants vaporize, thus absorbs a large amount of heats, and what the fan at evaporimeter place was produced by boasting is exactly cold wind; When heating, the turnover air exhaustion of compressor being commutated, exchanging by original condenser and evaporimeter.
Fig. 3 is the Temperature and Humidity Control structural representation of the utility model radon chamber constant temperature and humidity automaton, and arrow points is air flow; In humidity control system, air in radon chamber is blown over evaporimeter by fan, after temperature reduces, send in radon chamber through fan by circulating line, as needed to heat up, being commutated by humidity control system compressor, is evaporimeter in radon chamber, air in radon chamber is blown into by fan, sends in radon chamber after atmosphere temperature rising through fan by circulating line; When air humidity regulates, radon room air is introduced in humidity control system by fan, and as needed humidification, then air is by humidifier, and the air after humidification is sent in radon chamber by circulating line by fan, if dehumidifying is then through dehumidifier, sent in radon chamber through circulating line by fan after dehumidifying.
Described radon chamber constant temperature and humidity automaton, concrete implementation step is as follows.
1. temperature regulates: the temperature in temperature sensor Real-Time Monitoring radon chamber, outputs signal after amplifying, by the ADC port processing of STM32 to controller, and is converted to actual temperature value; When temperature is higher than setting value, humidity control system starts refrigerating function, and cold-producing medium absorbs heat in evaporimeter, air is lowered the temperature in evaporimeter surrounding, air in passing through fan and circulating line and radon chamber carries out temperature exchange, when temperature reaches setting value, stops refrigeration; When temperature is lower than setting value, the air inlet of compressor and outlet side are switched, the loop direction of air-conditioning system changes, former evaporimeter becomes condenser, air heats up around condenser, carry out temperature exchange by the air in fan and circulating line and radon chamber again, when temperature reaches setting value, heat stopping.
2. humidity regulation: the humidity in humidity sensor Real-Time Monitoring radon chamber, outputs signal after amplifying, by the ADC port processing of STM32 to controller, and is converted to actual humidity value; When humidity is higher than setting value, air is introduced dehumidifier, after dehumidifier dehumidifying, the air in passing through fan and circulating line and radon chamber circulates, and when humidity reaches setting value, humidity control system quits work, and closes radon chamber air insertion switch; When humidity is lower than setting value, air is introduced in humidifier, then by fan and circulating line and radon indoor air circulation, until humidity value reaches setting value, stop humidity regulation, close circulating path.
3. Presentation Function: when radon chamber runs, LED is the running status instruction of current Temperature and Humidity Control, and LCD display, for showing warm and humid angle value real-time in radon chamber, is convenient to understand timely the humiture situation in radon chamber.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, anyone amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
