Bear when oxygen content in air is 19.5% -20.5%, the growth of optimum chicken class, therefore in program setting, contain in setting air
The oxygen amount upper limit is 20.5%, and oxygen content lower limit is adjustable, but adjusting range is 19.5% or so.
The utility model solves the technical scheme that its technical problem used：A kind of environmental control system, including control
Device, guidance panel, frequency converter, blower fan, exhaust fan, frequency conversion fan, heating subsidiary engine, oxygen sensor, temperature sensor and electricity
Source, police instruction unit.Present apparatus controller uses chip microcontroller, and programmable logic controller (PLC) also can be used（PLC）Deng tool
The unit for having programming in logic to control realizes that its course of work is as follows：
1. guidance panel presets control parameter, it is necessary to parameter set in advance includes：
Oxygen content in air limit value, code 00；
Blower fan minimum ventilation rate, code 01；
Blower fan start sets temperature, code 10, and computing formula is：Blower fan start sets temperature=blower fan turn-on temperature-benchmark
Temperature；
Blower fan shutdown sets temperature, code 11, and computing formula is：Blower fan shutdown sets temperature=blower fan shutoff temperature-benchmark
Temperature；
Alarm temperature lower limit, code 50；
The alarm temperature upper limit, code 51；
Heat the turn-on temperature of subsidiary engine, code 70；
The shutoff temperature of subsidiary engine, code 71 are heated, this temperature is the fiducial temperature that each blower fan starts；
Exhaust fan function is selected, and code 90,0000 is blower fan pattern, and 0001 is Timer modes；

Value is according to the arranges value being finely adjusted using the different process of oxygen sensor.
2. oxygen concentration sensor and temperature sensor detect the oxygen content and temperature in hen house confined space, by numerical value
It is sent to environmental control.
3. the preliminary setting parameter and the state modulator heating of each sensor input that controller is input into according to guidance panel are used
Subsidiary engine, exhaust fan, blower fan or the operation by frequency converter adjustment frequency conversion fan.
（1）Temperature in adjustment hen house.
According to code 70, the setting value of code 71, when setting temperature of the temperature less than code 70, heating subsidiary engine starts,
Hen house is heated；When temperature rises to 71 design temperature of code, heating subsidiary engine is stopped.
（2）Adjustment oxygen content in air.
Blower fan quantity is set according to hen house scale, and the work of blower fan is influenceed by two factors of temperature and oxygen content simultaneously, first
First, with fiducial temperature（Code 71）It is basic point, sets a temperature range（Code 10, code 11）, ensureing temperature in hen house
On the premise of blower fan just devote oneself to work；Again, according to the value of feedback of oxygen sensor（Code 00）Determine live load（Code
01）.Computing formula is as follows：
Blower fan entry condition is：Hen house temperature >=blower fan start sets temperature（Code 10）+ fiducial temperature（Code 71）
Blower fan stop condition is：Hen house temperature≤blower fan shutdown sets temperature（Code 11）+ fiducial temperature（Code 71）
Blower fan works by Maximum Ventilatory Volume：The lower limit of oxygen content in air≤setting in hen house（Code 00）
Blower fan works by minimum ventilation rate（Code 01）：The higher limit of oxygen content in air >=setting in hen house（Code 00）

The frequency conversion fan of control is substituted, and advantage is that frequency conversion fan rotating speed is adjustable, and the control to oxygen content in hen house is more accurate.
Frequency converter observes the frequency of display in the case of missed electric machine, and frequency change is directly proportional to rotating speed.Ventilation 0-
100% corresponding frequency converter frequency 0-50Hz.Therefore, 20% ventilation correspondence frequency converter is about 10Hz in the case of constant speed.If
Put step as follows：
Adjust the oxygen content and minimum ventilation rate of controller
It is 19.5% to set oxygen content, and it is 20.0% to set ventilation, if currently displaying oxygen content is more than or equal to
20.5%, represent that now oxygen content meets and require, controller will export minimum ventilation rate, can now check the display of controller frequently
Rate should be 10Hz or so.If the gain of the DA outputs of the larger adjustable controller of difference.
Adjust the Maximum Ventilatory Volume of controller：
After upper step is good, can slightly blow oxygen sensor position, artificially decline the oxygen content of display, when the oxygen of display
When content is less than 19.5%, it is 50Hz or so that the frequency display of frequency converter is won（Maximum output）, as frequency shows not fine-tuning enough control
The DA outputs of device processed.
Heating subsidiary engine, blower fan, exhaust fan and speed-changing draught fan have automatically and manually two kinds of control models.
（3）Start warning device.
According to code 50, the setting value of code 51, when temperature is less than alarm temperature lower limit or higher than alarm temperature in hen house
During the upper limit, alarm starts, and the warning light LT2 on control panel is lighted, alert when temperature is between alarm temperature upper and lower limit
Report stops, and warning light LT2 is in OFF state.
（4）Start exhaust fan.
Exhaust fan does not add temperature conditioning unit, start and stop not temperature influence, as available ventilation miscellaneous function.In code
90 be 0000 Timer modes when, timer start timing, timer unit be " minute ", now exhaust fan stops completely；When
Code 90 switches to 0001 blower fan pattern, and exhaust fan starts.By this pattern, it is possible to resolve outside temperature-control range, the ventilation of hen house is changed
Gas problem.
（5）Oxygen content compensation is set
Because oxygen sensor is that part is easily lost, service life is about 1 year, more than 1 year its precision may under
Drop, can be compensated, code 91, the oxygen content concentration of compensating operation Display panel according to particular condition in use by setting oxygen content.
Setting scope is 0-25.0, and when general parameters is every increase by 1.0%, display oxygen content increases about 0.1%（Non-linear increase）.
When the kilobit of code 91 is set to 1, oxygen detection function is closed.
This controller includes control loop and performs loop, and performing loop has No. 8 relay output KA1-KA8, all the way
Frequency conversion exports KA9；Control loop installs lightning protection, surge device G1 additional；Control loop has power supply indicator LT1,3 phase circuit breaker Q F1
