Description

A kind of Laboratory Temperature humidity regulation device
Technical field
The utility model belongs to the electron controls technology field, is specifically related to a kind of SCM Based Laboratory Temperature humidity regulation device.
Background technology
Temperature and humidity is the most basic environmental baseline in laboratory, is also on the larger factor of experimental result impact.Temperature and humidity measurement in the common laboratory temperature and humidity control system all adopts thermistor and humicap, this traditional analog Temperature Humidity Sensor generally all needs modelled signal modulate circuit and complicated calibration and the calibration process of process, therefore measuring accuracy is difficult to guarantee, and also has some problems at aspects such as the linearity, repeatability, interchangeability.
This sensor is only suitable for those measurements less, not high to accuracy requirement occasion of counting.Therefore design that a precision is high, good stability, Temperature/Humidity Control System that cost is low will have certain market.Native system adopts the digital transducer SHT11 of advantages such as having high precision, anti-tampering, does not need outer member, can adaptive various single-chip microcomputers.This humiture observation and control system for Development of New Generation provides advantage, also helps the humiture observation and control technology is brought up to new level simultaneously.
Summary of the invention
The purpose of this utility model be to provide a kind of use have high precision, can jamming-proof Laboratory Temperature moisture control system.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of Laboratory Temperature humidity regulation device, it is characterized in that, device comprises single-chip microcomputer, Temperature Humidity Sensor, display, well heater and humidifier, described single-chip microcomputer is provided with input end and output terminal, described Temperature Humidity Sensor is connected with the input end of single-chip microcomputer, and described display, well heater and humidifier are connected with the output terminal of single-chip microcomputer.
The utility model also has following technical characterictic:
Described single-chip microcomputer adopts the AT89C52 single-chip microcomputer.
Described Temperature Humidity Sensor is the SHT11 digital temperature-humidity sensor.
Compared with prior art, the utlity model has following features:
(1) device of the present utility model adopts the digital temperature-humidity sensor of advantages such as having high precision, anti-tampering, does not need outer member, can adaptive various single-chip microcomputers.
(2) device of the present utility model has the function of controlling simultaneously laboratory temperature and humidity, can reach set control index, and has stable, the accurate and easy to operate characteristics of result.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is the circuit block diagram of device of the present utility model.
Embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, one concrete Laboratory Temperature humidity regulation device comprises single-chip microcomputer, Temperature Humidity Sensor, display, button, well heater and humidifier, described single-chip microcomputer is provided with input end and output terminal, described Temperature Humidity Sensor is connected with the input end of single-chip microcomputer, and described display, button, well heater and humidifier are connected with the output terminal of single-chip microcomputer.
Wherein, single-chip microcomputer adopts the AT89C52 single-chip microcomputer, and Temperature Humidity Sensor is the SHT11 digital temperature-humidity sensor, is installed in the laboratory, can export through the relative humidity of absolute calibration and the digital signal of temperature, is convenient to the integrated of the system that realizes; Button is arranged on display, and well heater and humidifier are installed in the laboratory.
When the utility model is in running order, through Temperature Humidity Sensor, the temperature in laboratory, humidity value is directly changed into as sending in single-chip microcomputer after digital quantity, and corresponding humiture value is shown by display screen.The input data are carried out the data processing through single-chip microcomputer by predetermined algorithm, carry out the deviation computing with the control target of setting, finally by I/O mouth output real-time control signal.During less than the initial value that arranges, single-chip microcomputer will make well heater (or humidifier) start working or change its working strength by controlling output interface when indoor temperature (or humidity); During the initial value that arranges greater than (or equaling) when the temperature in the greenhouse (or humidity), single-chip microcomputer quits work control heater (or humidifier).
