Description
Technical field
This utility model relates to the monitoring technical field of isolator, is specifically related to a kind of isolator multi fan and controls system
System.
Background technology
Isolation technology is the technology that controlled space and external environment condition are mutually completely cut off by a kind of means using physical barriers.?
When isolator produces or detects, according to medicine in cabin or the toxicological characteristics of article to be tested, when there is leakage to protect medicine
When being main and harmless, need in isolator to remain malleation, when occur leakage time harmful thus with protection
When personnel are main, need in isolator to remain negative pressure.Meanwhile, in order to ensure the purification of internal medium, often also need to protect
In holding cabin, air flows by certain speed, and such isolator needs many group blower fans to control pressure reduction and the wind of internal diverse location
Speed, it is desirable to system can be to organizing blower fan the most quickly regulation, with the pressure reduction within formation and wind speed requirement more.
Utility model content
In order to solve the deficiency in above-mentioned technical problem, the purpose of this utility model is: provide a kind of isolator with many
Blower fan control system, it is possible to realize the quick speed governing to group blower fans many in isolator and monitoring in real time.
The technical scheme that this utility model is used by its technical problem of solution is:
Described isolator multi fan control system, including isolator, isolator is connected with PLC system, isolator
Inside is provided with blower fan, PLC system be connected to HMI, HMI include processor, display unit, input block, data storage cell and
Communication interface, PLC system is connected by communication interface with HMI, and PLC system is connected and converter by ProfinetIO bus
Being connected, the other end of converter is connected with blower fan, and the display unit of described HMI also sets up start and stop module, fault recognition
Module and wind speed arrange module.
Further preferably, blower fan includes multiple, and each blower fan passes through ProfinetIO bus and PLC after concatenating converter
System is connected.
Compared with prior art, this utility model has the advantages that
This utility model novel structure, easy to use, it is possible to quick speed governing and the real-time prison to group blower fans many in isolator
Control, makes to remain inside isolator negative pressure.
Accompanying drawing explanation
Fig. 1 this utility model structured flowchart.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
Embodiment 1
As it is shown in figure 1, isolator multi fan control system described in the utility model, including isolator, isolator and PLC
System is connected, and the inside of isolator is provided with blower fan, and blower fan is for regulating the pressure reduction within isolator, and PLC system is connected to
HMI, HMI include processor, display unit, input block, data storage cell and communication interface, and PLC system and HMI are by logical
Communication interface is connected, and PLC system is connected by ProfinetIO bus and is connected with converter, can control instruction be transferred to
Converter, and the information such as rotation speed of fan, fault message and start and stop state, the other end of converter and blower fan is read from converter
Being connected, converter is used for controlling rotation speed of fan and start and stop, the display unit of described HMI also sets up start and stop module, fault true
Recognize module and wind speed arranges module；HMI mainly shows the state of blower fan, and can input the control instruction that blower fan is relevant.
Wherein, blower fan includes multiple, and each blower fan passes through ProfinetIO bus and PLC system phase after concatenating converter
Connect.
To each converter one unique remote ip address of distribution and title in PLC system, simultaneously at converter end
Arranging corresponding local address, such PLC can find each converter by address, when PLC receives opening from HMI
After the instruction of stop instruction, fault recognition, rotating speed arrange instruction, can quickly navigate to corresponding converter, by always by address
Line transmission control message is to this converter, and owing to employing bus mode, each converter, by the parallel control of PLC, can connect simultaneously
Receive the different instruction from PLC.Meanwhile, in order to be monitored rotation speed of fan, preventing blower fan overlond running, PLC also will be from
Each converter reads the running status of blower fan, rotating speed and fault alarm information etc., in order to make a response fault in time.This
It is prior art that utility model realizes the computer program of this function, it is not necessary to pay creativeness.
