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
Exemplified 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 to control 1 group of speed change
Exemplified 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；
When temperature is higher than ceiling temperature, i.e. after 30 DEG C of ＞, now speed-changing draught fan is temperature controlled, no matter now ammonia concentration
To be 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 default 3 DEG C of ceiling temperature (temperature detected be 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 default 3 DEG C of ceiling temperature (temperature detected 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, is protected if water pump is not run
Hold continuation halted state；
When temperature is more than default 3 DEG C of ceiling temperature (temperature detected be 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, starts stop step by step.What is set opens
Dynamic order should be by 1,2,3,4,5,6, and the stopping order of setting 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 section of temperature, and the temperature in 20-30 DEG C of section is divided into six points, used
In the startup and stopping that controlling six groups of constant speed blower fans；When temperature reaches 20 DEG C, first group of blower fan automatic start；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 temperature in 20-30 DEG C of section
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 temperature in the section is divided into several parts, controls the startup temperature of several groups of blower fans respectively
Degree.
N is the blower fan group number of access, and a is lower limit temperature, and b is ceiling temperature；Then in a-b temperature ranges, point of startup
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 start-up operation：
Each element is connected with equipment with wire according to correct mode；
Total power switch 5 on opening operation panel 2, whole system are powered, and total power light 4 is lighted.
Temperature, humidity, the upper lower limit value of ammonia concentration and preservation are set on the liquid crystal display 7 on guidance panel 2, protected
Deposit complete rear liquid crystal display 7 and enter main interface.
After the completion of parameter setting, operating system enters Auto-Sensing Mode, detects speed-changing draught fan, wet curtain and n group constant speed blower fans
Running situation, faulty equipment is checked whether there is, and all running situation is recorded in STM32 single-chip microcomputers, as normal fortune
Capable data sample.
After System self-test, system can close all 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, the stopping interval time of every group of constant speed blower fan is 1S, after the stopping of all constant speed blower fans, stops water pump after 1S.I.e. every group sets
Standby stopping interval time is all 1S, so can effectively prevent that immediate current is 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, appropriateness and ammonia on liquid crystal display in the current house of meeting real-time display
Gas concentration.Run indicator can be run with corresponding equipment and light, and malfunction indicator lamp detects corresponding equipment
Normal operation is then shown in green, detects that equipment is shown in red after breaking down.
Guidance panel is provided with hand switch button, the corresponding shift knob of every group of equipment.When use automatically controls,
All switches it is all initial be in " OFF " closed mode；When system breaks down or because special circumstances need artificially to start it
In one group or whole of equipment when, switch corresponding to equipment can be switched to " ON " opening, skip and automatically control, force fortune
Row relevant device.Manually operated start and stop can arbitrarily start regardless of order, stop any Fans.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
