Description
Technical field
The utility model relates to the Ventilation Control technology, specifically, is the terminal wind control device that becomes of a kind of ventilating system.
Background technology
Ventilation Control for present large-scale ventilating system; All be to come the ventilation requirement in the conditioning chamber at the terminal hand switch that adopts that ventilates mostly, its automaticity is lower, can not monitor in real time the room ventilation situation; Can not do demand supply air quantity; Be easy to cause the bad people's of influence of room ventilation quality of life, it is too quick perhaps to ventilate, and causes unnecessary waste for air-conditioning and ventilating system itself.Personnel are on duty to be monitored and regulates ventilated environment if take, and not only labor intensive is more, and the accuracy of control is also relatively poor.
And has only main air blower in traditional ventilation tradition; Terminal unpowered device; Add flow-limiting valve and guarantee hydraulic equilibrium, but so just cause main air blower proximal pressure air quantity big easily, the remote pressure air quantity is little; Can not the little or calm situation of complete solution far-end wind, can not rationally supply according to demand.
The utility model content
The purpose of the utility model is to propose the terminal wind control device that becomes of a kind of ventilating system; Can detect IAQ; Can control automatically rotation speed of fan and ventilation volume; Can also the running status of the blower fan form through RS485 be fed back to far-end control device, calculate the duty that required total blast volume is controlled main air blower through far-end control device.
For achieving the above object, the scheme that the utility model adopted is following:
The terminal wind control device that becomes of a kind of ventilating system; Be provided with controller and power conversion module; Said controller is by the power conversion module for power supply, and its key is: the input at said controller is connected with the air quality sensor, and first output of this controller is connected with the 0-10VDC analog output module; The output of this 0-10VDC analog output module is electrically connected with air intake machine and exhaust blower, also parallel air intake air-valve and the air draft air-valve of being connected with of second input of said controller.
Controller is through the air quality in the air quality sensor in real time sensing chamber; Judge the size of indoor required ventilation according to the quality of air quality; Thereby realize the automatic control of rotation speed of fan and ventilation volume; The control signal of the different voltages of output behind the control signal process 0-10VDC analog output module of controller output, the rotation speed of fan that different output voltage is corresponding different, thus realize control to blower fan.
Be connected with the RS485 module on the COM1 of said controller.
The RS485 module can reach far-end control device with the running status of the blower fan form through RS485, calculates the duty that required total blast volume is controlled main air blower through far-end control device, is convenient to the personnel's of monitoring remote monitoring.
Said air intake air-valve is installed between air intake machine and the intake stack, and said air draft air-valve is installed between exhaust blower and the exhaust duct.
The control signal of second output output of said controller is the switching value signal.
Through the air quality in air quality sensor detection room, controller output switching value signal is controlled the open and-shut mode of air intake air-valve and air draft air-valve, if the room does not need to ventilate, then closes air intake air-valve and air draft air-valve.
The remarkable result of the utility model is: can detect in real time IAQ; Controller can be according to the quality control rotation speed of fan and the ventilation volume of IAQ; The monitoring personnel not only can be through the long-range ventilation state of checking each room; And the ventilation situation that can gather each room controls main air blower work, reaches the purpose of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
As shown in Figure 1; The terminal wind control device that becomes of a kind of ventilating system; Be provided with controller 3 and power conversion module 4, said controller 3 is by 4 power supplies of power conversion module, is connected with air quality sensor 2 at the input of controller 3; First output of this controller 3 is connected with 0-10VDC analog output module 5; The output of this 0-10VDC analog output module 5 is electrically connected with air intake machine 6 and exhaust blower 7, and also parallel air intake air-valve 8 and the air draft air-valve 9 of being connected with of second input of said controller 3 is connected with RS485 module 1 on the communication ends group of controller 3.
In the practical implementation process, it is the singlechip chip of STC12C5A08AD that controller 3 adopts the chip model, and RS485 module 1 adopts MAX1487 as acp chip; Power conversion module 4 is made up of transformer, rectification circuit and mu balanced circuit; Wherein transformer is made up of the transformation coil, and rectification circuit adopts the DB107 rectifier bridge, and mu balanced circuit adopts 7805 and 7812 voltage stabilizing chips; Being used to provides+5V and ± dc source of 12V; Each chip all has the reference connecting circuit of standard, is well known technology, repeats no more at this.
Dissipate in order to reduce wind-force unnecessary in the air channel, said air intake air-valve 8 is installed between air intake machine 6 and the intake stack, and said air draft air-valve 9 is installed between exhaust blower 7 and the exhaust duct.
