Technical Field

[0001] The present invention relates to the technical field of digital management of buildings, and in particular to a visualization device-influenced space management system based on the Internet of Things. Background Art

[0002] At present, the spaces where people move have different requirements for ventilation, cooling, heating, etc. In actual scheme design, the specific layout scheme is basically formulated by the designer based on historical experience. After the specific layout is implemented, the situation of "failure to meet the use needs" or "over-configuration" often occurs. The former brings many troubles to the subsequent use process, and the latter causes serious waste of resources.

[0003] In view of this, this application is hereby filed. Summary of the invention

[0004] The purpose of the present invention is to provide a visual equipment impact space management system based on the Internet of Things, which can provide a reference for solution designers, so that they can more reasonably plan ventilation, cooling, heating and other solutions, and can effectively improve the accuracy of the solution and avoid the problems of failure to meet usage needs and over-configuration.

[0005] The embodiment of the present invention is achieved as follows:

[0006] A visual equipment impact space management system based on the Internet of Things includes: a monitoring end and a management end. The monitoring end includes: a test mechanism, a detection circuit and a processing module. The test mechanism includes: a mounting frame and a matching shaft.

[0007] The mounting frame is used to be installed on the periphery of the air outlet and is arranged in the vertical direction. The matching shaft is rotatably matched with the mounting frame and is arranged in the horizontal direction. In the vertical direction, multiple matching shafts are arranged at intervals on the mounting frame. Each matching shaft is fixedly connected to a counterweight. In the natural state, the counterweight is located directly below the matching shaft, which is recorded as the initial state.

[0008] The mounting frame is also provided with a slide groove, which continuously extends into an arc shape along the circumference of the matching shaft, and the groove wall of the slide groove is provided with a conductive belt extending along its length direction. The matching shaft is fixedly connected with a slider, which slides and fits in the slide groove. The slider is made of conductive material, and the slider is attached to the conductive belt and is electrically conductive.

[0009] Each matching shaft is correspondingly provided with a detection circuit, the slider is connected to one pole of the detection circuit, and one end of the conductive belt is connected to the other pole of the detection circuit.

[0010] The processing module is connected to the management end for communication, so as to send the detection data of the detection circuit to the management end. The management end is used to determine the affected space of the air outlet in the visualization model according to the detection data.

[0011] Furthermore, when the management end determines the outlet angle and wind speed of the air outlet according to the detection data, an analysis process is executed. The analysis process includes the following steps:

[0012] S1. Determine the deflection angle of the corresponding matching axis according to the current detected by the detection circuit, and determine the reference wind speed at the corresponding matching axis according to the deflection angle.

[0013] S2. Determine the divergence angle of the air outlet according to the distribution of the deflected mating axis on the mounting frame.

[0014] S3. Determine the airflow field of the air outlet in the visualization model according to the divergence angle and the reference wind speed.

[0015] S4. Determine the affected space of the air outlet according to the air flow field.

[0016] Further, S4 includes the following steps:

[0017] S41. Set a critical wind speed and construct a constant velocity surface corresponding to the critical wind speed in the airflow field.

[0018] S42, taking the space near the air outlet on the isovelocity surface in the airflow field as the first influencing space of the air outlet.

[0019] The first impact space corresponds to the area that can be directly blown by the air outlet.

[0020] Furthermore, S4 includes the following steps:

[0021] S43: Set the influence distance, and shift the boundary of the first influence space outward by a distance corresponding to the influence distance to obtain a critical boundary.

[0022] S44. The space within the critical boundary and outside the first influence space is taken as the second influence space.

[0023] The second impact space corresponds to the area that the airflow from the air outlet can actually affect.

[0024] Furthermore, the analysis process also includes the following steps:

[0025] S5. Determine the personnel activity area and the personnel height data, shift the ground of the personnel activity area upward by a distance corresponding to the personnel height data, and obtain a control surface. The area between the control surface and the ground is used as the activity three-dimensional area.

[0026] S6. Adjust the height of the air outlet and / or adjust the outlet wind speed of the air outlet so that the entire three-dimensional activity area is located within the second influence space.

[0027] Furthermore, when the air outlet is located in the indoor space and the second impact space determined by S44 intersects with the wall of the indoor space, the extension process is performed. The extension process includes the following steps:

[0028] D1. Calculate the spatial volume of the second impact space determined by S44 on the wall and the ground of the indoor space away from the air outlet, and record it as the residual volume.

[0029] D2. Calculate the spatial volume in the indoor space that is not covered by the second impact space determined by S44 and the first impact space determined by S42, and record it as the gap volume.

[0030] D3. If the surplus volume is larger than the gap volume, the second impact space is extended at the passage of the indoor space, and the extended volume is equal to the difference between the surplus volume and the gap volume.

[0031] Furthermore, in D3, when the second influence space is extended at the passage of the indoor space, the extension divergence space is determined according to the difference between the extension divergence angle, the residual volume and the gap volume at the passage.

[0032] Furthermore, in S6, if the active three-dimensional area cannot be completely located within the second influence space, a calculation process is executed. The calculation process includes the following steps:

[0033] H1. Determine the second influence space and extended divergence space corresponding to the maximum wind speed allowed at each air outlet.

[0034] H2. Construct a test plane for each air outlet, and set the test plane perpendicular to the outlet direction of the corresponding air outlet. Determine the intersection area of ​​the test plane with the second influence space and the extension divergence space, record it as the first intersection area, and make the area of ​​the first intersection area the largest.

[0035] H3. Use the distance between the test plane and the air outlet as a reference to set the height.

[0036] H4. Set the limit spacing distance, arrange the air outlets in the personnel activity area according to the reference setting height, and make the distance between the first intersection areas corresponding to adjacent air outlets less than or equal to the limit spacing distance.

[0037] H5. Provide the manager with the layout plan of the air outlets that complies with H4.

[0038] Furthermore, the management end is also used to execute the maintenance planning process, which includes:

[0039] All air outlets are divided into n batches of maintenance objects, where n≥2. The n batches of maintenance objects cover all air outlets.

[0040] For any batch of maintenance objects, determine the intersection area between the second influence space and the extended divergent space of the air outlet outside the maintenance object and the ground, which is recorded as the second intersection area. The second intersection area meets the following conditions: the spacing between adjacent second intersection areas is less than or equal to the limit spacing distance.

[0041] Furthermore, the management end is also used to execute the design planning process, which includes:

[0042] Arrange the air outlets for the object space so that the total number is minimized while meeting the requirements of S6 and the maintenance planning process.

[0043] The beneficial effects of the technical solution of the embodiment of the present invention include:

[0044] During use of the visualization device impact space management system based on the Internet of Things provided by an embodiment of the present invention, when the airflow blown out of the air outlet blows toward the counterweight, the counterweight will drive the matching shaft to rotate, thereby causing the matching shaft to deflect. At this time, the slider slides along the slide groove, and the position of the slider on the conductive belt changes, causing the connection length of the conductive belt connected to the detection circuit to change, the resistance value in the detection circuit changes, and the current changes accordingly. Therefore, the rotation of the matching shaft can be determined by the current change data in the detection circuit. The management end is used to determine the impact space of the air outlet in the visualization model based on the detection data. The impact space can show the area that the airflow of each air outlet can actually affect, so that the designer can more reasonably plan the specific design scheme of the air outlet, and it is also convenient for the management personnel in the actual use process to manage each air outlet.

[0045] Based on the impact space of each air outlet, we can know the role of each air outlet in promoting the cold source (cooling), heat source (heating) and ventilation (fresh air), so as to more reasonably determine and adjust the cooling, heating and ventilation plans.

[0046] In general, the IoT-based visualization equipment impact space management system provided by the embodiments of the present invention can provide a reference for solution designers, facilitating them to more reasonably plan ventilation, cooling, heating and other solutions, which can effectively improve the accuracy of the solution and avoid the problems of failure to meet usage needs and over-configuration.

Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list.

[0059] The flowcharts used in this specification are used to illustrate the operations performed by the system according to the embodiments of this specification. It is understood that the operations of each step are not necessarily performed precisely in order. On the contrary, the steps can be processed in reverse order or simultaneously. At the same time, other operations can also be added to these processes, or one or more operations can be removed from these processes.

[0060] In order to overcome the shortcomings of the prior art, please refer to Figure 1~Figure 3 This embodiment provides a visual device impact space management system based on the Internet of Things, which includes a monitoring end and a management end (not shown in the figure). The monitoring end includes a test mechanism 100, a detection circuit 200 and a processing module (not shown in the figure). The test mechanism 100 includes a mounting frame 110 and a mating shaft 120.

[0061] The mounting frame 110 is used to be mounted on the periphery of the air outlet 500 (it should be noted that the air outlet 500 in this application refers to the air outlet 500 disposed at the top of the activity space, i.e., the air outlet 500 blowing from top to bottom) and is disposed in the vertical direction. Along the circumference of the air outlet 500, a plurality of mounting frames 110 are evenly spaced.

[0062] The matching shaft 120 is rotatably matched with the mounting frame 110 and is arranged in the horizontal direction, and each mounting frame 110 is matched with a plurality of matching shafts 120. In the vertical direction, the plurality of matching shafts 120 are arranged on the mounting frame 110 at intervals.

[0063] Each of the mating shafts 120 is fixedly connected with a counterweight 130. In a natural state, the counterweight 130 is located directly below the mating shaft 120, which is recorded as an initial state. The counterweight 130 can be plate-shaped.

[0064] Specifically, the mounting frame 110 is provided with a matching blind hole 111 for matching with the end of the matching shaft 120 , and both ends of the matching shaft 120 are rotatably matched with the mounting frame 110 .

[0065] A slide groove 112 is also provided at the bottom of the matching blind hole 111 of the mounting frame 110. The slide groove 112 extends continuously in an arc shape along the circumference of the matching shaft 120. The groove wall of the slide groove 112 is provided with a conductive belt 113 extending along its length direction. The conductive belt 113 is made of conductive material, and the resistance per unit length of the conductive belt 113 is equal.

[0066] The end surface of the mating shaft 120 is fixedly connected with a slider 121 . The slider 121 is slidably matched in the slide groove 112 . The slider 121 is made of a conductive material. The slider 121 is attached to the conductive belt 113 and is electrically connected.

[0067] Each matching shaft 120 is correspondingly provided with a detection circuit 200 , the slider 121 is connected to one pole of the detection circuit 200 , and one end of the conductive belt 113 is connected to the other pole of the detection circuit 200 .

[0068] When the airflow from the air outlet 500 blows toward the counterweight 130, the counterweight 130 drives the mating shaft 120 to rotate, thereby causing the mating shaft 120 to deflect. At this time, the slider 121 slides along the slide slot 112, and the position of the slider 121 on the conductive belt 113 changes, causing the connection length of the conductive belt 113 connected to the detection circuit 200 to change, and the resistance value in the detection circuit 200 changes, and the current changes accordingly. Therefore, the rotation of the mating shaft 120 can be determined by the current change data in the detection circuit 200.

[0069] Under different wind forces, the counterweight 130 drives the matching shaft 120 to rotate at different angles. The greater the wind force, the greater the rotation angle.

[0070] The processing module is connected to the management end for sending the detection data (i.e., the current change data) of the detection circuit 200 to the management end. The processing module realizes the association between the monitoring end and the management end in the sense of the Internet of Things, so that the management end can monitor and manage the monitoring end in a unified manner.

[0071] The management end is used to determine the influence space of the air outlet 500 in the visualization model according to the detection data. The influence space can show the area that the airflow of each air outlet 500 can actually affect, so that the designer can more reasonably plan the specific design scheme of the air outlet 500, thereby facilitating the optimization of the original design of the air outlet 500, or upgrading the layout of the existing air outlet 500, and also facilitating the management personnel to manage each air outlet 500 during actual use.

[0072] Based on the impact space of each air outlet 500, it is possible to know the promoting effect of each air outlet 500 on the cold source (cooling), heat source (heating) and ventilation (fresh air), so as to more reasonably determine and adjust the cooling, heating and ventilation plans.

[0073] The visualization model can be flexibly selected according to actual needs, including but not limited to: a three-dimensional model of a building. After the influence space of the air outlet 500 is determined, the influence space corresponding to the air outlet 500 can be highlighted in the visualization model for intuitive observation.

[0074] In general, the IoT-based visualization equipment impact space management system provided in this embodiment can provide a reference for solution designers, allowing them to more reasonably plan ventilation, cooling, heating and other solutions, which can effectively improve the accuracy of the solution and avoid problems such as failure to meet usage needs and over-configuration.

[0075] In this embodiment, when the management end determines the outlet angle and wind speed of the air outlet 500 according to the detection data, an analysis process is executed. The analysis process includes the following steps:

[0076] S1. Determine the deflection angle of the corresponding mating shaft 120 according to the current detected by the detection circuit 200, and determine the reference wind speed at the corresponding mating shaft 120 according to the deflection angle. The reference wind speed is the wind speed when the airflow from the air outlet 500 blows to the counterweight 130.

[0077] S2. Determine the divergence angle of the air outlet 500 according to the distribution of the deflected mating shaft 120 on the mounting frame 110 (e.g. Figure 1 The angle α shown in the figure). When the divergence angle of the air outlet 500 is different, the number of the counterweights 130 that can be blown in the vertical direction is different. Therefore, the divergence angle of the air outlet 500 can be determined by determining which matching shafts 120 have their corresponding currents of the detection circuits 200 changed, that is, which matching shafts 120 have deflected. It should be noted that the arrangement density of the matching shafts 120 in the vertical direction on the mounting frame 110 can be flexibly adjusted according to actual needs, which can affect the measurement accuracy of the divergence angle.

[0078] S3. Determine the airflow field of the air outlet 500 in the visualization model according to the divergence angle and the reference wind speed, that is, determine the actual flow of the airflow blown out of the air outlet 500 in combination with aerodynamics. Figure 4 shown.

[0079] S4. Determine the influence space of the air outlet 500 according to the air flow field.

[0080] Specifically, S4 includes the following steps:

[0081] S41. Set the critical wind speed (the critical wind speed can be flexibly set according to actual needs, for example, it can be set to the maximum wind speed at which the human body will not feel uncomfortable), and construct a constant velocity surface corresponding to the critical wind speed in the airflow field. Figure 4 As shown, the critical wind speed v0 corresponds to the constant velocity surface X.

[0082] S42, taking the space on the side of the isovelocity surface in the air flow field close to the air outlet 500 as the first influencing space of the air outlet 500.

[0083] The first affected space corresponds to an area that can be directly blown by the air outlet 500. Generally speaking, the wind speed in this area is relatively high, and the air flow is more obvious.

[0084] Furthermore, S4 includes the following steps:

[0085] S43, setting the influence distance, shifting the boundary of the first influence space outward by a distance corresponding to the influence distance, and obtaining a critical boundary. The influence distance refers to the distance that can promote air movement (the flow intensity that cannot be obviously perceived by the human body) under the action of the airflow in the first influence space. The influence distance can be flexibly set according to actual conditions.

[0086] S44. The space within the critical boundary and outside the first influence space is taken as the second influence space.

[0087] The second influence space corresponds to the area that can be actually affected by the airflow of the air outlet 500. Generally speaking, under the action of the air outlet 500, the air in the second influence space can move accordingly, which plays a role in promoting air circulation.

[0088] For the first impact space and the second impact space, the analysis process also includes the following steps:

[0089] S5. Determine the personnel activity area and the personnel height data, shift the ground of the personnel activity area upward by a distance corresponding to the personnel height data, and obtain a control surface. The area between the control surface and the ground is used as the activity three-dimensional area.

[0090] S6. Adjust the height of the air outlet 500 and / or adjust the outlet wind speed of the air outlet 500 so that the entire active three-dimensional area is located within the second influence space.

[0091] In this way, the people in the three-dimensional activity area can have a better sense of body. In the design of the air outlet 500, it can provide a design reference for the designer; in the actual use management process, it can provide a reference for the management personnel to adjust each air outlet 500.

[0092] It should be noted that the above situation does not take into account the problem of wall obstruction. In other words, it is more applicable to situations where the indoor space is large and there is no direct contact with the wall, or where temporary air supply solutions are built in some open-air or semi-open-air venues.

[0093] It should be noted that the visualization model used in this application refers to a three-dimensional model of a building with corresponding air outlets 500 arranged. For open-air venues and semi-open-air venues, corresponding three-dimensional models of the open-air venues and semi-open-air venues can be established.

[0094] In particular, when the air outlet 500 is located in an indoor space (for example, in a room), and the second impact space determined by S44 intersects with the wall of the indoor space, the extension process is executed. It should be noted that whether the air outlet intersects with the wall is used as the basis for determining whether the extension process is executed. This is because if the air outlet does not intersect with the wall, it means that the airflow blown out by the air outlet 500 can basically only affect the room where it is located, and the impact on other rooms can be ignored.

[0095] Specifically, the epitaxial process includes the following steps:

[0096] D1. Calculate the spatial volume of the second influence space determined by S44 on the side of the wall and the ground of the indoor space away from the air outlet 500, and record it as the residual volume. That is, first determine the second influence space according to S41 to S44 without considering the wall and the ground, and then determine the residual volume according to the relationship between the determined second influence space and the actual wall and ground.

[0097] D2. Calculate the volume of the space in the indoor space that is not covered by the second impact space determined by S44 and the first impact space determined by S42, and record it as the gap volume. If there is only one air outlet 500 in the indoor space, the gap volume is determined by subtracting the volume of the first impact space and the second impact space of the air outlet 500 from the total volume of the indoor space. If there are multiple air outlets 500 in the indoor space, the gap volume can be determined by subtracting the volume of the first impact space and the second impact space of all air outlets 500 from the total volume of the indoor space.

[0098] D3. If the surplus volume is greater than the gap volume, the second affected space is extended at the passage of the indoor space, and the extended volume is equal to the difference between the surplus volume and the gap volume. It should be noted that the "passage" here is a broad concept, referring to the channels connecting the indoor space with other spaces, including but not limited to: doors, windows, other openings, etc.

[0099] Among them, in D3, when the second influence space is extended at the channel of the indoor space, the extended divergence space is determined according to the difference between the extended divergence angle, the residual volume and the gap volume at the channel. The extended divergence angle at the channel can be calculated in combination with the actual aerodynamics at the channel, or the divergence angle at the channel can be directly and reasonably stipulated artificially for the convenience of management and calculation. The specific form can be flexibly selected.

[0100] In this way, the actual influence range (including: extended divergent space) of the second influence space of each air outlet 500 can be evaluated more comprehensively, so that designers and relevant managers can carry out related work more reasonably.

[0101] Furthermore, in S6, if the active three-dimensional area cannot be completely located within the second influence space, a calculation process is executed. The calculation process includes the following steps:

[0102] H1. Determine the second influence space and the extended divergence space corresponding to the maximum wind speed allowed by each air outlet 500.

[0103] H2. Construct a test plane for each air outlet 500, and the test plane is set perpendicular to the outlet direction of the corresponding air outlet 500. Determine the intersection area of ​​the test plane with the second influence space and the extension divergence space, record it as the first intersection area, and make the area of ​​the first intersection area the largest.

[0104] H3. Use the distance between the test plane and the air outlet 500 as a reference to set the height.

[0105] H4. Set the limit spacing distance, arrange the air outlets 500 in the personnel activity area according to the reference setting height, and make the spacing between the first intersection areas corresponding to adjacent air outlets 500 less than or equal to the limit spacing distance. The limit spacing distance needs to meet the following requirements: when people walk in the interval area between two first intersection areas, that is, when walking from the first intersection area of ​​one air outlet 500 to the first intersection area of ​​another air outlet 500, it is calculated according to the normal walking speed of people at this position, and people will not feel uncomfortable (for example: too cold, too hot, stuffy, etc.) when passing through this area. The limit spacing distance is related to the actual situation of the environment and can be flexibly set according to the actual situation.

[0106] H5. Prompt the manager with the arrangement plan of the air outlet 500 that complies with H4.

[0107] The calculation process can help designers take better care of people's physical feelings when the number of air outlets is limited to 500.

[0108] Furthermore, the management end is also used to execute the maintenance planning process, which includes:

[0109] All the air outlets 500 are divided into n batches of maintenance objects, where n is a positive integer and n≥2. The n batches of maintenance objects cover all the air outlets 500.

[0110] For any batch of maintenance objects, the intersection area between the second influence space and the extended divergent space of the air outlet 500 outside the maintenance object and the ground is determined and recorded as the second intersection area. The second intersection area satisfies the following conditions: the spacing between adjacent second intersection areas is less than or equal to the limit spacing distance.

[0111] This design can help managers to reasonably plan maintenance plans during actual use, and avoid significant deterioration in the physical sensation of people in the area due to maintenance of the air outlet 500.

[0112] Furthermore, the management end is also used to execute the design planning process, which includes: arranging the air outlets 500 for the object space so that the requirements of S6 and the requirements of the maintenance planning process are met with the minimum total number.

[0113] In this way, the designer can reserve sufficient operating space for batch maintenance of the air outlet 500 during the design stage, thereby avoiding affecting the physical sensations of people in the area during the maintenance process.

[0114] To sum up, the IoT-based visualization equipment impact space management system provided by the embodiment of the present invention can provide a reference for solution designers, so that solution designers can more reasonably plan ventilation, cooling, heating and other solutions, which can effectively improve the accuracy of the solution and avoid the problems of failure to meet usage needs and over-configuration.
