Bio-incubator makes incubator temperature control precision using old-fashioned temperature control method, it is difficult to ensures the temperature that microorganism fungus kind needs
Degree.Application No. 201620030184.0, the Chinese patent of entitled " SCM Based incubator ", it solve only to training
The temperature inside the box and the control of time are supported, the humidity in inaccurate control incubator, and humidity is also to influence the growth of strain
The key condition of breeding；In addition, also without reference to bactericidal unit in the technical scheme of the patent, and conventional bactericidal unit due to
There is no timing function, cause sterilizing not thorough, cultivation results is produced very big difference yet.Therefore, it is necessary to develop a kind of temperature,
Humid control is accurate, has the incubator based on Automatic control of single chip microcomputer of clock automatically timing and regulatory function.
Utility model content
The purpose of this utility model is to provide a kind of control of temperature and humidity accurate, has automatic clock timing and regulation
The incubator based on Automatic control of single chip microcomputer of function.
The purpose of this utility model is achieved in that including casing, and rack, heating plate, humidification are provided with casing
Device, temperature sensor, humidity sensor and ultraviolet sterilizing lamp, casing front panel are provided with display screen and button, and this practicality is new
Type also includes single chip computer automatic control system, and single chip computer automatic control system includes analog signal input block, Signal Pretreatment
Unit, A/D converters, power supply, button, single-chip microcomputer, D/A converters and analog signal output unit；Analog signal input block
Including the temperature sensor, humidity sensor and ultraviolet sterilizing lamp being electrically connected with single-chip microcomputer；Analog signal output unit bag
Humidifier regulating valve, electric hot plate regulating valve, display screen, data storage and the sterilamp ON/OFF for including single-chip microcomputer electric connection are determined
When device.
Further, single-chip microcomputer uses 89S52 as control chip.
Further, temperature sensor is WZP-A type Pt100 temperature sensors.
Further, humidity sensor is electric resistance moisture sensor.
Further, display screen uses LED display.
Further, A/D converters select MC14433 converters.
Further, D/A converters select AD667 converters.
The beneficial effects of the utility model are：Temperature sensor, humidity sensor and ultraviolet are gone out by A/D converter
The simulation that bacterium lamp collects changes into data signal, then these data signals are inputted in single-chip microcomputer, is passed through after single-chip microcomputer is handled
Certain analog circuit is crossed to realize the functions such as the switch to each control element, regulation, timing and data display storage；Due to this
A little elements have higher precision, the epidemic disaster in incubator can be monitored in real time, to the follpet of ultraviolet sterilizing lamp
There is timing function, avoid the randomness of manual control, can relatively accurately simulate microorganism and cell, bacterial growth are bred
Ecological environment, ensure the epidemic disaster needed for each microorganism fungus kind, promote them to grow.

Fig. 2 is the theory diagram of Automatic control of single chip microcomputer；
In figure：1- heating plates, 2- racks, 3- single-chip microcomputers, 4- humidifiers, 5- buttons, 6- display screens, 7- TEMPs
Device, 8- ultraviolet sterilizing lamps, 9- humidity sensors.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not subject in any way
Limitation, any changes and modifications made based on the utility model training centre, belongs to the scope of protection of the utility model.
As shown in Figure 1-2, the utility model includes casing, and rack 2, heating plate 1, humidifier 4, temperature are provided with casing
Degree sensor 7, humidity sensor 9 and ultraviolet sterilizing lamp 8, casing front panel are provided with display screen 6 and button 5, and its feature exists
In：Also include single chip computer automatic control system, single chip computer automatic control system includes analog signal input block, Signal Pretreatment
