The Main Function of speed-changing draught fan is the ventilation in winter pig house, reduces ammonia concentration in pig house, its operating speed
Degree is controlled by ammonia concentration in pig house and temperature, when temperature is less than the default interval threshold values peak of temperature in pig house, change
The running speed of fast blower fan is influenceed by ammonia concentration value, and the running speed of speed-changing draught fan is with the rising increase of ammonia concentration；
When temperature is higher than the default interval threshold values peak of temperature in pig house, speed-changing draught fan full-speed operation.
STM32 single-chip microcomputers are built-in with self-check program, and after opening total power switch, whole system is powered, STM32 single-chip microcomputer meetings
Start built-in self-check program, the equipment for being connected to control system is run one by one, whether the equipment that so both have detected access has
Failure, at the same again by equipment stable operation when data STM32 single-chip microcomputers are transferred to by current detector, record in program
It is used to detect equipment fault as sample.
The ammonia of this control system, humidity, the bound of temperature can be adjusted according to the actual requirements.Below with ammonia concentration
Lower limit 0ppm, ammonia concentration upper limit 20ppm, humidity lower limit 80%, top limit of humidity 95%, 20 DEG C of lowest temperature, temperature upper limit 30
As a example by DEG C.
This control system can control 1 group of speed-changing draught fan, 1 group of wet curtain and n group constant speed blower fans, below controlling 1 group of speed change
As a example by blower fan, 1 group of wet curtain and 6 groups of constant speed blower fans.
1 group of frequency conversion fan is controlled by ammonia concentration and temperature.
When temperature is less than ceiling temperature, i.e. 30 DEG C of ＜, now speed-changing draught fan is controlled by ammonia concentration, and speed-changing draught fan is most
The low speed of service be 20%, with ammonia concentration from 0ppm be increased to 20ppm when, the rotating speed of speed-changing draught fan is increased to from 20%
100%, after ammonia concentration is more than 20ppm, speed-changing draught fan then full speed running；
After temperature is higher than ceiling temperature, i.e. 30 DEG C of ＞, now speed-changing draught fan is temperature controlled, no matter now ammonia concentration
It is how many, speed-changing draught fan all full-speed operations.
1 group of wet curtain is controlled by humidity and temperature.
When temperature is more than 3 DEG C of default ceiling temperature (temperature for detecting is higher than 33 DEG C), and humidity is less than lower limit
During humidity 80%, the starting mode of pump of wet curtain；
When temperature is more than 3 DEG C of default ceiling temperature (temperature for detecting is higher than 33 DEG C), humidity is higher than lower limit humidity
80%, less than threshold moisture 95%, state now is continued to run with if water pump is currently running, protected if water pump does not run
Hold continuation halted state；
When temperature is more than 3 DEG C of default ceiling temperature (temperature for detecting is higher than 33 DEG C), but humidity is higher than the upper limit
When 95%, the water pump of wet curtain is out of service, and after humidity descends below lower limit humidity 80%, the water pump of wet curtain starts running again；
6 groups of constant speed blower fans are controlled by temperature.
6 groups of blower fans according to STM32 single-chip microcomputers set automatically different start and stop temperature values realize temperature control automatic sequence start with
Stop, the start and stop temperature value of blower fan group subtracts lower limit temperature mean allocation according to ceiling temperature, start stop step by step.What is set opens
Dynamic order should by 1,2,3,4,5,6, the stopping of setting order should be by 6,5,4,3,2,1 modes.
Run after setting as follows：
6 groups of constant speed blower fans are opened one by one in 20-30 DEG C of interval of temperature, and the temperature in 20-30 DEG C of interval is divided into six points, are used
In control six groups of startups and stopping of constant speed blower fan；When temperature reaches 20 DEG C, first group of blower fan automatic；When temperature reaches
During 20+ (30-20)/6 DEG C, first and second group of blower fan starts；By that analogy, when temperature reaches 20+4* (30-20)/6 DEG C, first
Start to five groups of blower fans；When temperature reaches 30 DEG C, the first to six group constant speed blower fans all start.
If only accessing 5 groups of blower fans, set by the internal processes of STM32 single-chip microcomputers, can be by the 20-30 DEG C of temperature in interval
It is divided into five points.According to identical principle, 5 groups of blower fans are opened one by one.
It is several groups to access blower fan group number, then the interval temperature is divided into several parts, and several groups of startup temperature of blower fan are controlled respectively
Degree.
N is the blower fan group number for accessing, and a is lower limit temperature, and b is ceiling temperature；Then in a-b temperature ranges, startup point
Unit number is n groups, n≤6.The hygrometric formula that then every group of blower fan starts is f (n)=a+ (n-1) (b-a)/n.Equipment starts behaviour
Make：
Each element and equipment are connected with wire according to correct mode；
Total power switch 5 on opening operation panel 2, whole system is powered, and total power light 4 is lighted.
Temperature, humidity, the upper lower limit value of ammonia concentration are set on the liquid crystal display 7 on guidance panel 2 and are preserved, protect
Deposit complete rear liquid crystal display 7 and enter main interface.
After the completion of parameter setting, operating system enters Auto-Sensing Mode, detection speed-changing draught fan, wet curtain and n group constant speed blower fans
Ruuning situation, checks whether there is faulty equipment, and all of ruuning situation record in STM32 single-chip microcomputers, as normal fortune
Capable data sample.
After System self-test is finished, system can close all of equipment, to prevent from simultaneously closing off the electric current spark mistake of relay
Greatly, equipment stops one by one in order.Equipment stopping order be：Stop speed-changing draught fan first, several groups of constant speed blower fans stop one by one after 1S
Only, every group of stopping interval time of constant speed blower fan is 1S, after after the stopping of all constant speed blower fans, water pump is stopped after 1S.I.e. every group sets
Standby stopping interval time is all 1S, so can effectively prevent immediate current excessive, jamming decision.
If detecting the equipment normal operation of all access systems, system will be automatically into intelligent operation pattern.If inspection
Measuring the equipment of access system has operation troubles, alarm meeting automatic alarm, while liquid crystal display can also show specific event
The equipment of barrier, facilitates operating personnel to repair.
After system enters intelligent operation pattern, temperature in current house, appropriateness and ammonia can be in real time shown on liquid crystal display
Gas concentration.Run indicator can be lighted with the operation of corresponding equipment, and malfunction indicator lamp detects corresponding equipment
Normal operation is then shown in green, detects shown in red after equipment breaks down.
Guidance panel is provided with hand switch button, every group of equipment one shift knob of correspondence.When using automatically controlling,
All of switch is all initial in " OFF " closed mode；Broken down when system or because special circumstances need artificially to start it
In one group or whole equipment when, the corresponding switch of equipment can be switched to " ON " opening, skip and automatically control, force fortune
Row relevant device.Manually operated start and stop can arbitrarily start, stop any Fans regardless of order.
General principle of the invention, principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.
