[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Application Overview

[0033] Double-layer orifice plate is a common ventilation method, which plays the role of exchanging air inside and outside the orifice plate, adjusting the temperature inside and outside the orifice plate, and adjusting the ventilation rate. The position relationship of the double-layer orifice plates is parallel to each other, and there is only a small gap between the orifice plates. The orifice plates move back and forth in a straight line, and the purpose of adjusting the ventilation rate is achieved by using the air to enter the room through the orifice plate with several circular or slit-shaped holes. The ventilation rate of the double-layer orifice plate is related to factors such as the size and shape of the holes on the double-layer orifice plate, the space of the blocked holes, and the pressure difference inside and outside the double-layer orifice plate. The advantage of double-layer orifice plate ventilation is uniform ventilation. Because the holes on the orifice plate are consistent in size and shape, arranged regularly, and evenly distributed, the ventilation is uniform, and there will be no local insufficient or excessive ventilation, thereby ensuring the air quality indoors and outdoors. However, the above-mentioned traditional method of adjusting the ventilation rate with a double-layer orifice plate. There are the following problems:

[0034] When the operating knob is turned by hand, the orifice plate moves back and forth (see attached Figure 1 ) is inefficient, and turning the operating knob is laborious and inconvenient for actual operation;

[0035] When the operating knob is turned by hand, the reciprocating motion of the orifice plate is not smooth and there is a jam;

[0036] The operating knob is adjusted in several gears, and the through-hole rate cannot be adjusted arbitrarily within a certain adjustment range;

[0037] When the distance is far, the operation and maintenance personnel cannot reach the site immediately, and the ventilation rate cannot be adjusted in time;

[0038] The purpose of the present invention is to provide a ventilation method for adjusting ventilation rate by double-layer orifice plates, which has labor-saving operation, smooth orifice plate movement, and can realize manual, automatic and remote control.

[0039] Specifically, this patent can realize manual adjustment, automatic temperature adjustment, remote control adjustment, and stepless adjustment of ventilation rate, ensuring that the orifice plate moves back and forth smoothly without jamming, and is more labor-saving during operation. The entire system is composed of a control system and a motion system. The control system: consists of a circuit board (welding chips and other components), a touch screen, PC programming software, a network switch, and a digital temperature controller. The motion system: consists of electric and pneumatic structural methods for pushing the orifice plate, and transmission methods such as slide rails and guide rails at both ends of the orifice plate. The specific working method for adjusting the ventilation rate of the double-layer orifice plate is as follows:

[0040] Stepless adjustment of through-hole rate: The through-hole rate can be adjusted arbitrarily within the adjustment range. The stepless adjustment of the through-hole rate is achieved by means of the operation programming between displacement and force. The program is burned into the chip of the circuit board. The program sets the output force to push the orifice plate to move a certain distance to meet the adjustment of the through-hole rate within a certain adjustment range. The distance the orifice plate moves is controlled by increasing or decreasing the output force.

[0041] The orifice plate can move back and forth smoothly without jamming: the strength of the double-layer orifice plate can be improved, such as increasing the thickness of the orifice plate, making a reinforced structure, etc., to ensure the flatness of the double-layer orifice plate and achieve no bending or deformation under force during the movement of the orifice plate.

[0042] According to the convenience of intelligent adjustment and operation by operation and maintenance personnel, we have divided the control system into three levels. When the operation and maintenance personnel adjust the ventilation rate on site, they can adjust the ventilation rate through manual control. When the operation and maintenance personnel are not on site, we adjust the ventilation rate through automatic or remote control. Remote control is based on automatic control.

[0043] Manual control: The touch screen is connected to the orifice plate control system. By sliding your finger on the multi-function touch screen or pressing the "+" or "-" key, a command signal is sent to the control system to increase or decrease the ventilation rate. The control system makes circuit feedback, and the chip program sends corresponding instructions according to the type of signal feedback from the circuit. The signal is transmitted to the motion system, and the electric, pneumatic and other structures will push the orifice plate to move, thereby achieving the effect of manually adjusting the ventilation rate.

[0044] Automatic control: The program for increasing or decreasing the ventilation rate is set according to the temperature difference between the internal and external environments of the double-layer orifice plate. A digital thermostat is installed on the side of the double-layer orifice plate with temperature requirements to detect the current value of its temperature control. The temperature probe of the thermostat can convert the temperature signal into an electrical signal, which is transmitted to the control system, ultimately achieving the effect of automatically adjusting the ventilation rate.

[0045] Remote control: The control system is connected to the network switch, and commands are sent to the control system through the network to achieve remote control, providing convenience for operation and maintenance personnel who cannot be on-site.

[0046] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0047] Exemplary Methods

[0048] Figure 1 The figure is a flow chart of a method for adjusting the ventilation rate of a double-layer orifice plate provided in an embodiment of the present application. The method is used to control the ventilation rate of a double-layer orifice plate of a ventilation system; the ventilation system comprises: a control system, a motion system and a double-layer orifice plate; the control system is used to drive the motion system so that the motion system drives the double-layer orifice plate to move, so that different layers of orifice plates in the double-layer orifice plate move relative to each other, thereby changing the ventilation rate; Figure 1 As shown, the method for adjusting the ventilation rate of the double-layer orifice plate includes:

[0049] Step S101, obtaining an adjustment instruction;

[0050] This is the starting step of the entire adjustment process. Adjustment instructions can come from multiple channels, such as manually operated control panels, remote control devices, and instructions issued by automated systems based on preset conditions.

[0051] If it is a manual operation, the operator can input the adjustment instructions through a specific interface according to the actual ventilation needs. For example, in a factory workshop, when the production process changes and the ventilation rate needs to be adjusted to adapt to the new environmental requirements, the operator can input the instructions on the panel in the control room.

[0052] Remote control devices allow users to adjust ventilation systems from different locations. For example, managers can send adjustment instructions remotely from the office through a mobile phone application to adjust the ventilation conditions of a workshop or warehouse at any time.

[0053] A situation where the automation system issues instructions based on preset conditions. For example, when the indoor air quality sensor detects that the air quality has dropped to a certain level, the automation system will issue an adjustment instruction to increase the ventilation rate and improve the air quality.

[0054] Step S102, generating a control signal based on the adjustment instruction;

[0055] After receiving the adjustment instructions, the control system begins to play a core role and converts the instructions into specific control signals.

[0056] A control system usually consists of hardware and software. The hardware part includes processors, sensors, communication modules, etc., while the software part is responsible for processing instructions, executing algorithms and generating control signals.

[0057] First, the control system will analyze the adjustment command and determine the ventilation rate target value that needs to be adjusted. Then, according to the preset algorithm and the characteristics of the ventilation system, the corresponding control signal parameters are calculated. For example, if the adjustment command requires an increase in ventilation rate, the control system may calculate the distance and speed at which the double-layer orifice plate needs to be moved.

[0058] The generated control signal is usually transmitted in the form of an electrical signal with specific characteristics such as frequency, amplitude and waveform in order to accurately drive the motion system.

[0059] Step S103, driving the motion system through the control signal, so that the motion system drives the double-layer perforated plate to move, so that different layers of perforated plates in the double-layer perforated plate move relative to each other, thereby changing the ventilation rate.

[0060] This is a key step in achieving ventilation rate regulation; after the motion system receives the control signal, it converts it into mechanical power to drive the double-layer orifice plate to move. The motion system can use different drive methods such as motors, hydraulic devices, pneumatic devices, etc., depending on the design and requirements of the ventilation system. When the different layers of orifice plates in the double-layer orifice plate move relative to each other, the overlapping area of ​​the holes changes, thereby changing the ventilation rate. For example, if the holes of the two layers of orifice plates overlap completely, the ventilation rate is maximum; when the holes of the two layers of orifice plates partially overlap or do not overlap at all, the ventilation rate will decrease accordingly. By precisely controlling the movement of the motion system, the ventilation rate can be continuously adjusted to meet the ventilation needs in different scenarios. At the same time, the stability and reliability of the motion system are also crucial to ensure that the ventilation rate is accurately adjusted and can operate stably for a long time. A detailed introduction to the motion system

[0061] In some embodiments, the obtaining of adjustment instructions includes: obtaining adjustment instructions based on a preset local human-computer interaction device; or, obtaining adjustment instructions based on a human-computer interaction device connected by remote communication; or, automatically generating adjustment instructions based on a preset control strategy; or, collecting information based on a preset sensor; and generating adjustment instructions based on the collected information and a preset control strategy.

[0062] The following is a detailed description of the methods for obtaining adjustment instructions in these embodiments:

[0063] Get adjustment instructions based on local human-computer interaction device:

[0064] The local human-computer interaction device can be in various forms. For example, a control panel is set up at the site where the ventilation system is located, and the control panel may have interactive elements such as buttons, knobs, and touch screens.

[0065] The button can be used to implement some simple functions, such as turning the ventilation system on or off with one click, or switching different ventilation modes (such as normal ventilation mode, fast ventilation mode, etc.).

[0066] The knob can be used to continuously adjust the ventilation rate, and the operator can increase or decrease the ventilation rate value by rotating the knob.

[0067] The touch screen provides richer interactive functions. The current status information of the ventilation system (such as ventilation rate value, operation mode, etc.) can be displayed on the touch screen, and the operator can operate by touching the virtual buttons and sliders on the screen, such as accurately setting the ventilation rate value or selecting different control strategies.

[0068] The advantage of this approach is that operators can quickly operate on site according to actual conditions. For example, if workers in a certain area of ​​an industrial plant feel that the ventilation is not smooth, the on-site operator can immediately go to the control panel and quickly adjust the ventilation rate through buttons, knobs or touch screens to meet the comfort needs of the on-site workers.

[0069] The human-machine interaction device based on the remote communication connection obtains the adjustment instruction:

[0070] Use network technology to achieve remote communication connection. The control system of the ventilation system can be connected to the remote human-computer interaction device through a wired network (such as Ethernet) or a wireless network (such as Wi-Fi, Bluetooth, ZigBee, etc.).

[0071] The remote human-computer interaction device can be dedicated software on a computer, an application on a mobile phone or tablet computer, etc.

[0072] This approach is suitable for large buildings or widely distributed facilities. For example, in a large hospital, there are multiple ward buildings and different department areas, and the ventilation system is widely distributed. When there is a problem with the ventilation system in a certain area or the ventilation rate needs to be adjusted, the operation and maintenance personnel do not need to go to the area in person, but can send adjustment instructions remotely through the software on the computer at the hospital's control center or use the relevant application on their mobile phone.

[0073] Its advantage is that it saves the time and energy of operation and maintenance personnel and improves operation and maintenance efficiency. At the same time, in some special circumstances, such as during the epidemic, it reduces the flow and contact of personnel and reduces the risk of infection.

[0074] Automatically generate adjustment instructions based on preset control strategies:

[0075] The control strategy can be set based on a variety of factors. For example, it can be set based on time. During the day, different time periods may have different requirements for ventilation rates. For example, during office hours, when there are many people, a higher ventilation rate may be required; while during non-office hours, when there are fewer people, the ventilation rate can be reduced to save energy.

[0076] It can also be set according to the ambient temperature. When the ambient temperature is higher than a certain threshold, an instruction to increase the ventilation rate is automatically generated to reduce the indoor temperature; when the ambient temperature is lower than another threshold, an instruction to reduce the ventilation rate is automatically generated to keep the indoor temperature stable.

[0077] It can also be set according to air quality. When the air quality sensor detects that the indoor air quality is poor, it automatically generates an instruction to increase the ventilation rate to improve the indoor air quality as soon as possible.

[0078] This automatic generation of adjustment instructions reduces manual intervention and improves the system's automated operation capabilities. The system can automatically adapt to environmental changes according to preset strategies, without the need for operators to constantly pay attention and adjust, thus improving the operating efficiency and stability of the ventilation system.

[0079] Collect information based on preset sensors; generate adjustment instructions based on the collected information and preset control strategies

[0080] There are many kinds of sensors that may be installed in the ventilation system. Temperature sensors are used to detect indoor and outdoor temperature information, humidity sensors are used to detect indoor and outdoor humidity information, and air quality sensors are used to detect indoor air quality (such as pollutant concentration, oxygen content, etc.).

[0081] These sensors collect relevant information in the environment in real time and transmit it to the control system.

[0082] The control system generates adjustment instructions based on the collected sensor information and the preset control strategy. For example, when the temperature sensor detects that the indoor temperature is too high and the humidity sensor detects that the humidity is moderate, according to the preset control strategy, an instruction to increase the ventilation rate may be generated to reduce the indoor temperature. If the air quality sensor detects that the indoor air quality is poor and the temperature sensor detects that the indoor temperature is moderate, an instruction to increase the ventilation rate may be generated to improve the indoor air quality.

[0083] This method combines the real-time information collected by sensors with the preset control strategy to adjust the ventilation rate more accurately. It can adjust the ventilation rate in time according to the actual changes in the environment to achieve the best indoor environment adjustment effect.

[0084] Exemplary Systems

[0085] The system embodiment of the present application can be used to execute the method embodiment of the present application. For details not disclosed in the system embodiment of the present application, please refer to the method embodiment of the present application.

[0086] Reference Figure 2The ventilation system comprises: a control system 1, a motion system 2 and a double-layer orifice plate 3; the control system is used to drive the motion system so that the motion system drives the double-layer orifice plate to move, causing different layers of orifice plates in the double-layer orifice plate to move relative to each other, thereby changing the ventilation rate; wherein the control system is used to execute the above-mentioned method for adjusting the ventilation rate of the double-layer orifice plate.

[0087] Specifically, the ventilation system achieves ventilation rate adjustment through the coordinated work of three main parts. The control system, as the "brain", is responsible for issuing instructions and coordinating the operation of various parts; the motion system, as the "executor", drives the double-layer perforated plate to move according to the instructions of the control system; the double-layer perforated plate is the key component to achieve the ventilation function, and the relative movement of the different layers of perforated plates directly changes the ventilation rate.

[0088] The control system executes a method for adjusting the ventilation rate of the double-layer orifice plate, which covers a series of steps including obtaining adjustment instructions, generating control signals based on the instructions, and driving the motion system.

[0089] It can obtain adjustment instructions in a variety of ways, such as based on local human-computer interaction devices (facilitating on-site operation), human-computer interaction devices connected by remote communication (realizing remote control), automatic generation of preset control strategies (improving the degree of automation), and generation of control strategies based on sensor-collected information (realizing precise adjustment).

[0090] The control system components can be composed as follows:

[0091] Circuit board, on which chips and other components are soldered, are the basis for realizing control functions. The chip is responsible for running the program, processing various input information and issuing corresponding instructions.

[0092] The touch display provides a local human-computer interaction interface through which operators can intuitively view the status information of the ventilation system and perform manual adjustments, such as sending instructions to adjust the ventilation rate by touching a specific area or button on the screen.

[0093] PC programming software can be used to perform more complex settings and programming of the control system, such as setting different control strategies, adjusting the adjustment range and accuracy of the ventilation rate, etc.

[0094] The network switch is used to realize the remote communication function, so that the control system can transmit data with the remote human-machine interaction device, thereby receiving remote adjustment instructions.

[0095] Digital thermostat is used to detect ambient temperature and provide temperature information for automatic ventilation rate adjustment. When the ambient temperature changes, the digital thermostat converts the temperature signal into an electrical signal and transmits it to the control system. The control system adjusts the ventilation rate based on this temperature signal according to the preset strategy.

[0096] The motion system can be a pneumatic drive system or an electric drive system. The pneumatic drive system uses gas pressure to generate power to drive the double-layer orifice plate to move. It has the characteristics of fast response speed and strong force, and is suitable for some scenes with high requirements for ventilation rate adjustment speed. The electric drive system uses the torque generated by the motor to drive the double-layer orifice plate to move. It has the advantages of high control accuracy and smooth operation, and is more suitable for some occasions with high requirements for ventilation rate adjustment accuracy.

[0097] The double-layer orifice plate moves relative to each other through the slide rail or guide rail. The slide rail and guide rail provide stable guidance and support for the movement of the double-layer orifice plate, ensuring that the orifice plate can maintain linear motion during the movement process, avoiding deviation or jamming, thereby ensuring the accuracy and stability of ventilation rate adjustment.

[0098] The position relationship of the double-layer orifice plates is parallel to each other, and there is only a small gap between the orifice plates. There are several circular or slit-shaped holes on the orifice plates. The size, shape and distribution of these holes will affect the ventilation rate.

[0099] When the two layers of the double-layer perforated plate move relative to each other, the size and shape of the ventilation space will change, thereby changing the ventilation rate. For example, when the two layers of perforated plates are relatively far away, the ventilation space increases and the ventilation rate increases; when the two layers of perforated plates are relatively close, the ventilation space decreases and the ventilation rate decreases.

[0100] Specifically, the motion system is a pneumatic drive system or an electric drive system.

[0101] The following is a detailed introduction to the two driving modes of the motion system:

[0102] The pneumatic drive system uses gas pressure to generate power to push the double-layer orifice plate to move. It usually consists of air source, pneumatic control valve, cylinder and other components.

[0103] The gas source provides gas with a certain pressure, such as compressed air. The pneumatic control valve is used to control the flow direction and flow of the gas. According to the control signal from the control system, the amount of gas entering the cylinder and the direction of pressure are adjusted. The cylinder is an actuator that converts gas pressure energy into mechanical energy. When the gas enters the cylinder, the piston in the cylinder will move under the action of the gas pressure, thereby driving the double-layer orifice plate connected to the piston to move.

[0104] The pneumatic motion system includes the following features:

[0105] Fast response speed: The compressibility of gas enables the pneumatic system to respond quickly after receiving the control signal and quickly adjust the position of the double-layer orifice plate to achieve rapid adjustment of the ventilation rate.

[0106] Greater force: Under the same working conditions, the pneumatic drive system can provide relatively large thrust, which is very beneficial for some application scenarios that require greater force to move the double-layer orifice plate. For example, in large ventilation equipment, when the double-layer orifice plate is large in size and heavy in mass, the pneumatic drive system can more effectively push the orifice plate to move.

[0107] The electric drive system drives the double-layer orifice plate to move through the torque generated by the motor. After receiving the control signal from the control system, the motor will rotate according to the signal requirements. The rotational motion of the motor is transmitted to the double-layer orifice plate through the transmission mechanism (such as belts, chains, gears, etc.), causing the double-layer orifice plate to produce corresponding displacement.

[0108] The electric drive system features are as follows:

[0109] High control accuracy: The electric drive system can achieve high-precision control of the movement of the double-layer orifice plate by accurately controlling the speed and direction of rotation of the motor. For example, the distance and speed of the double-layer orifice plate can be accurately adjusted, thereby adjusting the ventilation rate more accurately.

[0110] Smooth operation: The motor runs relatively smoothly without the jitter that may be caused by gas pressure fluctuations in pneumatic systems. This makes the double-layer orifice plate more stable during movement, which is conducive to the stable regulation of ventilation rate and can reduce equipment wear that may be caused by orifice plate jitter.

[0111] Specifically, the double-layer orifice plate moves relatively via a slide rail or a guide rail.

[0112] The slide rails and guide rails provide stable guidance and support for the relative movement of the double-layer perforated plate. They ensure that the double-layer perforated plate can maintain linear motion during movement, avoiding deviation or jamming, thereby ensuring the accuracy and stability of ventilation rate adjustment.

[0113] The slide rail is usually a long metal structure with a smooth surface, installed on one or both sides of the double-layer perforated plate. The guide rail cooperates with the slide rail and is generally installed on the other side of the double-layer perforated plate (if there are slide rails on both sides) or in the position corresponding to the slide rail (if there are slide rails on only one side). The shape and size of the guide rail match the slide rail to ensure that the double-layer perforated plate can move smoothly between the slide rail and the guide rail.

[0114] Slide rails and guide rails are generally made of metal materials with high strength and hardness, such as aluminum alloy, stainless steel, etc. These materials can withstand the weight of the double-layer orifice plate and the friction generated during movement, and have good wear resistance to ensure long-term reliability.

[0115] In order to ensure that the double-layer orifice plate can move smoothly on the slide rails and guide rails, the slide rails and guide rails need to be properly lubricated. You can use a special lubricant and apply it regularly on the surface of the slide rails and guide rails. At the same time, in daily maintenance, check whether the slide rails and guide rails are worn or deformed, and replace damaged parts in time to ensure the normal operation of the ventilation system.
