Description

Automatic door and window opening and closing control method and device, electronic equipment and storage medium

Technical Field

The application relates to the technical field of door and window control, in particular to a door and window automatic opening and closing control method, a device, electronic equipment and a storage medium.

Background

In modern buildings, automatic control systems for doors and windows have been widely used. These systems are typically equipped with an opening and closing device, a detector and a controller on the door and window. When the detector detects information (such as temperature, humidity, wind speed, coal gas, carbon monoxide, formaldehyde and the like) meeting preset conditions, the controller sends instructions according to the information to control the opening and closing device to open or close the door and window.

The invention discloses an automatic window opening device based on carbon monoxide concentration detection, which is disclosed in the Chinese patent application with publication number of CN109322583A, and the automatic window opening device can realize the automatic window opening effect by arranging a carbon monoxide concentration detection sensor, a first wireless communication module, a controller, a second wireless communication module and a window opening mechanism and controlling the window opening mechanism to perform window opening action through the controller after detecting that the carbon monoxide concentration exceeds the standard, wherein the first wireless communication module and the second wireless communication module play the function of information transmission.

The invention of China patent application with publication number CN105511322A proposes a system for detecting gas to control doors and windows, and the door and window can be automatically opened under the condition of gas leakage by arranging a gas sensor and a window pushing device for controlling the opening and closing of the doors and windows, so that intelligent control of the doors and the windows is realized.

The invention of China patent application with publication number CN107461107A provides an automatic opening and closing window based on a sensor, and particularly discloses that when smoke in a room exceeds a preset value, a motor rotates to open a door and window and gives an alarm, when the temperature rises to exceed the preset value, the motor rotates to close the door and window and open an air conditioner, if a humidity sensor outside a rainy window senses and closes the door and window, the time for automatically opening the door and window and the time for automatically closing the door and window can be set through a key, the door and window can be automatically closed or opened when the set time is reached, and the functions of controlling the opening and closing of the door and window according to the temperature and humidity and opening and closing the door and window according to the time can be set.

It has been found that by providing sensors to detect indoor and/or outdoor environmental information, controlling doors and windows to open and close automatically when preset conditions are reached is a very mature prior art.

However, it is neglected in the art that the above-mentioned prior art only controls the opening and closing of a single door and window, and opens and closes the door and window, which is essentially to realize the communication or the separation between the indoor and the outdoor, taking gas leakage as an example, when gas leakage occurs in the indoor, the indoor and the outdoor are usually required to be communicated, so as to avoid the too high concentration of the gas in the indoor, in the intrinsic cognition of the field, as long as the door and window are opened, the ventilation requirement can be met, thereby avoiding the problem that the concentration of the gas in the indoor is too high, because of the intrinsic cognition, the technical scheme related to the field is always remained after reaching the preset condition based on the detection of the detector, the corresponding door and window is controlled to open and close, and the influence of the position relation between the door and window arranged at different positions in the indoor is ignored, for example, the leakage usually occurs in the indoor kitchen position, when the gas leakage occurs in the prior art, the door and window at the position can detect the gas concentration rising, then be opened, however, if the outside is in the kitchen, the air is diffused from the outdoor, the outdoor is not diffused, the air is diffused, the dangerous condition is not generated, and the ventilation plug is not diffused, and the ventilation is easy, and the ventilation is not diffused to be carried out to the outdoor, and the outdoor air is in time, and the outdoor air is not diffused, and the ventilation is easy.

That is, most of the prior art, although it is possible to automatically control the door and window to automatically open and close the door and window to achieve the indoor and outdoor communication or blocking, has neglected the problem of how to improve the efficiency of achieving the indoor and outdoor communication or blocking after achieving the indoor and outdoor communication or blocking, and as the above example, the goal of achieving the indoor and outdoor communication is to diffuse the gas to the outside, although ventilation can be finally achieved by opening the door and window, the wind blowing from the outside toward the indoor will not be continued all the time, and ventilation can be finally achieved, and the gas will be diffused to the outside, however, the efficiency of diffusing the gas to the outside is not considered in the prior art, and the slower the efficiency of diffusing the gas to the outside, the greater the risk.

In the chinese patent application with publication number CN107461107a, an intelligent door and window system and an automatic control method thereof are proposed, when dealing with an emergency of gas leakage in a building, according to the specific situation of gas leakage, the method combines with the house type features in the building, calculates the theoretically optimal gas discharge scheme, plans to adopt natural ventilation and exhaust of a ventilation system, and when using natural ventilation to discharge gas, makes the gas discharge outside the building under the action of natural wind through the cooperation of the sequential opening and opening degrees of each door and window. And in the implementation process, the gas leakage risk is more intelligently and rapidly relieved according to the actually measured parameters in real time so as to reduce the energy waste.

The above prior art relates to linkage control of multiple doors and windows, however, the technical scheme of the linkage control needs to be in linkage control with a ventilation system, which needs to perform additional adaptation, that is, needs to perform unified control on the ventilation system, which brings difficulty and cost of adaptation work, and the ventilation system usually needs to use a motor to rotate at a high speed to realize ventilation during operation, and the motor rotating at the high speed can bring heat and friction, so that extra safety risks are brought during gas discharge.

Thus, improvements are needed in the art.

The first door and window is located in a kitchen area and is directly communicated with the outside, and can be opened or closed according to a control signal, and normally, one first door and window is arranged.

The second doors and windows are other doors and windows which are directly communicated with indoor and outdoor in a house, and a plurality of second doors and windows are usually arranged in each region of bedrooms, living rooms and the like in one house.

The third door and window is located on the first path, and the opening and closing of the third door and window are controlled to form an effective ventilation path, wherein the first path is a channel which is formed between the first door and window and the second door and window and can enable gas to flow, and when a plurality of second doors and windows exist, a plurality of corresponding first paths exist.

The wind direction information can be obtained by arranging a wind sensor, and the wind direction information can be detected, and the wind power can be detected.

Wherein, first door and window, second door and window and third door and window all are equipped with automatic opening and closing system, and automatic opening and closing system specifically can be including drive arrangement and controlling means, and controlling means controls drive arrangement action through signal trigger, thereby drive arrangement realizes automatic opening and closing through door and window structural connection, and automatic opening and closing system on door and window belongs to current conventional art, and unnecessary description here.

The application is different from the prior art in that the scheme of the application provides a functional object for determining the first door and window according to wind direction information, namely, determining the first door and window as a gas discharge air inlet or a gas discharge air outlet according to wind direction information, and executing different control strategies according to different wind direction information so as to ensure that leaked gas can be discharged outdoors in the shortest time, thereby ensuring safety.

In most of the prior art, the corresponding doors and windows are directly controlled to be opened after the gas exceeding standard is detected, the influence of the actual wind direction information on the gas going out is not considered, and in the Chinese patent application with publication number of CN107461107A, the proposal is considered to consider the influence of different wind directions on the gas discharge, however, in the technical proposal, the linkage control with a ventilation system is needed, and the situation that if the actual comprehensive wind direction is located in the negative direction of the vector, the doors and windows with the wind directions consistent with the negative direction of the vector are closed first, and then the ventilation system is opened is clearly described.

The prior art adopts a mode of linkage with a ventilation system, so that only the condition that doors and windows which are directly communicated with the outside in a kitchen are taken as air outlets, but not the condition that the doors and windows are taken as air inlets is considered, the scheme of the application determines the air inlets of the first doors and windows which are taken as gas discharge or the air outlets of the gas discharge based on the wind direction information of the first doors and windows and the second doors, and selects a gas discharge scheme based on the actual wind direction information under the condition that an additional ventilation system is not required to be controlled in a linkage mode, and the application has the advantages of low cost and high safety under the condition that the efficient discharge of the gas is ensured.

Specifically, referring to fig. 2, fig. 2 is a schematic indoor layout of a house, where the first door and window is a, the second door and window is B, C, D, E, that is, the first path at this time includes a-B, A-C, A-D, A-E, the third door and window is F, G, H, when the overall wind direction information is blown from north to south, that is, the wind direction information detected on the first door and window and the second door and window is all blown from north to south, for the second door and window C, it may not detect specific wind direction information, or the detected information is very weak, at this time, the wind direction information on the second door and window C may be deduced from the wind direction information detected on other third door and window and first door and window, because the wind direction information is blown from north to south, it may be determined that the functional object of the first door and window a is the air inlet for gas discharge, after the functional object of the first door and window a is determined, the first target door and window for the air outlet needs to be selected from the second door and window B, C, D, E, the second target door and window for the air outlet is assumed, the second target window for the gas outlet, and the second door and window B, C is the first target window for the air outlet, at this time, the first door and window is 35 a-35H, and the first door and window is controlled to be opened, and the third door and window is 35H.

Under the control strategy, the leaked gas in the kitchen is discharged outdoors along the first paths of A-B and A-C under the action of wind power blown from north to south, so that the efficient gas discharge is realized, and the safety effect is ensured.

It should be noted that, in the scheme of the present application, when the functional object of the first door and window is an air inlet for discharging gas, the first door and window, the first target door and window, and a third door and window on a first path corresponding to the first door and window and the first target door and window are controlled to be opened, and the other doors and windows are controlled to be closed, because when the first door and window is used as the air inlet, outdoor fresh air enters the room through the first door and window, gas can diffuse into the room, that is, the gas can diffuse into other areas in the room along with wind, and by closing the other doors and windows, the diffusion range of the gas can be limited to be concentrated in a specific area, and then the gas is discharged according to the specific first path, thereby reducing the range of discharging gas in the room.

Specifically, the step of determining the functional object of the first door and window according to the wind direction information includes:

Determining a first airflow flowing direction according to the corresponding wind direction information of the first door and window, wherein the first airflow flowing direction comprises flowing into the room from the outside or flowing out of the room from the outside;

Specifically, the step of screening the first target door and window as the air outlet for the gas discharge from the second door and window includes:

Determining a second airflow flowing direction according to the wind direction information corresponding to the second door window, wherein the second airflow flowing direction comprises flowing into the room from the outside or flowing out of the room from the outside;

Selecting a second door window with a second airflow flowing direction flowing out of the room from the room as a first target door window;

When the flow direction of the second air flow is determined according to the wind direction information corresponding to the second door window, whether the wind direction points to the second door window or faces away from the second door window can be judged according to the wind direction information, when the wind direction points to the second door window, an included angle formed by the wind direction and a plane where the second door window is located is in a range of 0-180 degrees (excluding 0-180 degrees), the flow direction of the second air flow can be considered to flow from outdoors into indoors, and when the wind direction faces away from the second door window, an included angle formed by the wind direction and the plane where the second door window is located is in a range of 0-180 degrees (including 0-180 degrees), and the flow direction of the second air flow can be considered to flow indoors out of outdoors.

The step of screening the second target door and window as the air inlet for discharging the coal gas from the second door and window comprises the following steps:

Determining a third airflow flowing direction according to the wind direction information corresponding to the second door window, wherein the third airflow flowing direction comprises flowing into the room from the outside or flowing out of the room from the outside;

And selecting a second door window, which flows from the outside into the room, as a second target door window.

When the flow direction of the third air flow is determined according to the wind direction information corresponding to the second door window, the direction of the wind can be firstly judged to be directed to the second door window or to face away from the second door window according to the wind direction information, when the direction of the wind is directed to the second door window, the included angle formed by the wind direction and the plane where the second door window is located is in the range of 0-180 degrees (excluding 0-180 degrees), the flow direction of the third air flow can be considered to flow from outside into the room, and when the direction of the wind is facing away from the second door window, the included angle formed by the wind direction and the plane where the second door window is located is in the range of 0-180 degrees (including 0-180 degrees), and the flow direction of the third air flow can be considered to flow from inside to outside of the room.

It should be noted that, according to different environments of a house, such as the influence of surrounding building environments, the wind forces actually received by doors and windows in different directions are not necessarily the same, that is, the doors and windows in different directions may be subjected to wind forces of different wind directions, taking fig. 2 as an example, the second door and window B may be subjected to wind blowing from east to west, the second door and window D may be subjected to wind blowing from west to east, when the first door and window a is used as an air outlet for discharging gas, the air inlet for discharging gas needs to be screened out from the second door and window, at this time, the second door and window B is subjected to wind blowing from east to west, the second door and window D is subjected to wind blowing from west, at this time, a specific wind speed can be obtained, the air inlet for discharging gas with a high wind speed is selected, for example, the wind speed of the second door and window B is 2m/s, the wind speed of the second door and window D is selected as the air inlet for discharging gas, at this time, the corresponding first paths are a-D, the third paths are a-D, and the first door and window, the third door and window are opened.

Preferably, the second door B is selectively closed in order to avoid blocking the air flow in the a-D path after opening.

That is, when there are a plurality of second windows as second target windows, it is determined whether there is a blocking effect between the second target windows based on wind direction information of the second target windows, and when there is a blocking effect, a window having a large wind speed as a final gas-discharging inlet is selected based on the wind speed, and then the second target windows having a relatively large blocking effect are controlled to be closed.

And through the shortest path, the gas can be discharged out of the chamber at the highest speed, so that the concentration of the gas in the chamber is rapidly reduced, and the risk of explosion or poisoning is reduced.

In addition, the short path means that the air flow resistance is small, the exhaust effect is better, and smooth exhaust of the coal gas is ensured.

The third air flow direction is selected as a second target door window which flows into the room from the outside and corresponds to the longest first path, the purpose of the third air flow direction is to fully diffuse fresh air through the longest first path, the second door window with the longest first path is selected as the second target door window, and the purpose of ensuring that fresh air can fully flow through all corners of the room and pushing coal gas to move towards an outlet is achieved, so that effective air convection is formed.

Fresh air is introduced through the longest path, so that the indoor air can be ensured to flow completely, dead angles are avoided, and the coal gas is ensured not to accumulate in certain areas

The second door window corresponding to the shortest first path is selected as the first target door window, so that gas can be rapidly discharged through a short path, the indoor residence time is reduced, the indoor gas concentration is reduced, and the potential safety hazard is reduced.

The second door window corresponding to the longest first path is selected as a second target door window, fresh air can be introduced through the long path, the whole indoor space can be ensured to form effective air convection, gas is pushed to flow towards the outlet direction, the gas is prevented from being detained in certain areas, and the comprehensiveness and the effectiveness of exhaust are improved.

And selecting a second door window with the second airflow flowing direction flowing out of the room from the priority as the first target door window.

Among them, room types typically include bedrooms, living rooms, restaurants, bathrooms, study rooms, storerooms, and the like.

The step of calculating the priority of each second door and window according to the room type specifically refers to setting different priorities for the second door and window corresponding to each room type, so as to determine which second door and window should be preferentially selected as the first target door and window.

Wherein the priority may be set in advance, in some embodiments the bedroom is the lowest priority, as this is the room for rest and should not be the main exhaust path.

Further, the priority can be adjusted according to time, the activity condition of users in different rooms in different time periods is different, and the priority of doors and windows can be adjusted according to the time periods.

The method comprises the following steps:

defining a time period: the day is divided into different time periods, such as morning, noon, afternoon, evening, night.

Adjusting priority: and adjusting the priority of the doors and windows according to the rooms in which the users are active in different time periods. For example:

noon (12:00-14:00): parlor and living room priorities are the lowest, as users typically have noon break in these rooms.

Night (22:00-6:00): bedrooms have the lowest priority because users are typically resting.

In addition, the priority of the doors and windows can be dynamically adjusted by detecting the activity condition of indoor personnel.

Specifically, whether personnel are active in a room or not is detected by using a sensor, the priorities of doors and windows are dynamically adjusted according to the personnel activity condition, the priorities of the second doors and windows corresponding to the room with the personnel activity are reduced, so that the influence of gas emission on personnel is reduced, the priorities of the second doors and windows corresponding to the room without the personnel activity are increased, and the second doors and windows are preferentially selected as first target doors and windows.

It is worth noting that after gas leakage occurs, each door and window can be provided with a warning module, such as a warning lamp or a buzzer, and corresponding warning information can be sent out after gas leakage occurs.

Further, in some of these embodiments, the steps of the method further comprise:

Acquiring the concentration of gas detected in a kitchen area;

the number of first target doors and windows required for calculation is calculated when the gas concentration is detected in the kitchen area.

The gas concentration can be monitored in real time through a gas sensor arranged in a kitchen area, and according to the detected gas concentration, the number of first target doors and windows which need to be opened is calculated to effectively discharge the gas in the room.

The corresponding relation between the gas concentration and the number of the first target doors and windows required can be set in advance, and the corresponding relation can be calculated in real time according to wind direction information and wind speed.

Specifically, the change condition of the gas concentration within the duration time can indicate that the current number of the first target doors and windows cannot meet the discharge requirement of the gas if the gas concentration is continuously increased, and the number of the first target doors and windows needs to be increased.

According to the application, the quantity required by the first target doors and windows is calculated, so that the control of energy source dawn is facilitated, and unnecessary energy consumption is reduced, and the unnecessary energy consumption is caused by opening too many unnecessary first target doors and windows. For example, in winter or summer, excessive opening of doors and windows can cause an increase in the workload of indoor temperature control systems, such as air conditioning or heating, resulting in energy waste, and in addition, unnecessary door and window actions are controlled.
