[0001] The application belongs to the technical field of Internet of Things, and particularly relates to a conference room device control method and device, electronic equipment and a storage medium. BACKGROUND

[0002] With the development of modern office mode towards high-efficiency cooperation, a conference has become a core scene for enterprise decision-making, communication and project promotion. In a frequent and long-duration conference process, since a conference room is usually in a relatively closed state, personnel are concentrated, and air circulation is limited, leading to rapid increase of carbon dioxide (CO2) concentration in the conference room. In the case of high temperature or CO2 concentration in the conference room, the human body will have the "brain fog" phenomenon of decreased attention, slow reaction, drowsiness, and slow thinking, thereby affecting information processing efficiency and conference decision-making quality.

[0003] Under normal circumstances, a conference organizer will manually open a smart air conditioner, a fresh air system and other air purifiers to purify the air in the conference room. However, the air purifiers on the market currently rely on time operation, manual operation or pollutant sensor detection of pollutant exceeding standard to start, and such passive response control strategy leads to air purification lagging behind actual demand, and cannot effectively alleviate the cognitive fatigue and drowsiness problems caused by air pollution. SUMMARY

[0004] The conference room device control method and device, electronic equipment and storage medium provided by the embodiments of the application can solve the problem that air purification lags behind actual demand in the prior art, and cannot effectively alleviate the cognitive fatigue and drowsiness problems caused by air pollution.

The adjustment module is used to adjust the second operating parameters of the air purification device based on the meeting schedule information or the air quality information.

[0007] Thirdly, this application provides an electronic device, including: a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the aforementioned equipment control method for the conference room.

[0021] Although the operations or steps are described in a specific order in the accompanying drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations or steps to be performed in the specific order or serial order shown, or requiring all the operations or steps to be performed to obtain the desired results. In the embodiments of the present disclosure, the operations or steps can be performed in series; the operations or steps can also be performed in parallel; or a part of the operations or steps can be performed.

[0022] With the development of modern office mode towards high-efficiency collaboration, meetings have become the core scene of enterprise decision-making, communication and project promotion. However, in the process of frequent and long-duration meetings, due to the fact that the conference room is usually in a relatively closed state, the personnel are dense, and the air circulation is limited, the carbon dioxide (CO2) concentration released by human respiration rises rapidly. Studies have shown that when the indoor CO2 concentration exceeds 800 parts per million (ppm), the human body will experience "brain fog" phenomena such as decreased attention, sluggish reaction, drowsiness, and slow thinking, which seriously affects information processing efficiency and meeting decision-making quality. This problem is particularly prominent in conference rooms without natural ventilation or insufficient fresh air systems.

[0023] The air purifiers on the market at present mainly rely on timing operation, manual operation or start after detecting that the pollutants exceed the standard based on fine particulate matter (PM2.5), total volatile organic compounds (TVOC) and other pollutant sensors, that is, the existing technology is a passive response control strategy. This "passive governance" mode causes air purification to lag behind actual demand, and cannot effectively alleviate the cognitive fatigue and drowsiness problems caused by air pollution.

[0024] Although part of the intelligent air conditioner or fresh air system has realized linkage with office schedule, realizing temperature control pre-start function, the technology has not been expanded to air purification field, and has not taken "preventing dozing off" as the core control target. It can be seen that the existing air purification scheme has the following problems: 1. In a long time meeting, the CO2 concentration in the closed space rises rapidly, and the "brain fog" phenomenon such as attention decline and drowsiness is caused after exceeding 800ppm, affecting the meeting efficiency.

[0025] 2. Air purification response lag problem: the existing equipment mostly depends on the increase of air volume after the pollutants exceed the standard, there is obvious delay, and it cannot actively intervene in the early stage of the meeting.

[0026] 3. Lack of meeting scene adaptability: the traditional purifier is not linked with the office system, and cannot dynamically adjust according to the meeting time, number of people and other information.

[0027] 4. No active anti-dozing mechanism: the products on the market generally stay at the "pollution control" level, and lack the design of preventing dozing off through air disturbance, body sensation stimulation and the like.

[0028] In order to solve the above technical problems, the embodiment of the present application provides a conference room device control method, device, electronic equipment and storage medium, which will be described in detail below in combination with the drawings, through specific embodiments and application scenarios.

[0029] Figure 1 It is a step flow chart of a conference room device control method provided by the embodiment of the present application, as shown in Figure 1 The method can include the following steps.

[0030] Step 101, according to the meeting schedule information and the air quality information, predicting the pollutant parameters of the conference room in the meeting process.

[0031] In the embodiment of the present application, the meeting schedule information at least includes the meeting starting time.

[0032] In some embodiments, the meeting schedule information further includes: meeting expected duration and number of participants.

[0033] In a possible implementation manner, the meeting schedule information includes the meeting starting time and the meeting ending time, and the meeting expected duration is calculated according to the meeting starting time and the meeting ending time.

[0034] In the embodiment of the present application, the conference room is the conference room where the air purification equipment is located.

[0035] In some embodiments, the air quality information comprises: a current indoor pollutant concentration, a current outdoor pollutant concentration, a single-person exhaled pollutant rate, and a fresh air volume. The pollutant can be CO2, PM2.5, TVOC, etc.

[0036] For example, the pollutant is CO2, and the pollutant sensor built in the air purification device can be a non-dispersive infrared (NDIR) CO2 sensor.

[0037] In the embodiments of the present application, the fresh air volume can be the amount of fresh air introduced from the outdoor to the indoor.

[0038] In some embodiments, the pollutant parameter comprises an increase rate of the pollutant concentration and a target pollutant concentration at a conference start time.

[0039] For example, the pollutant parameter comprises an increase rate of CO2 per minute and a CO2 concentration at a conference start time.

[0040] In some embodiments, the step 101 comprises: inputting the conference schedule information and the air quality information into a preset Ordinary Differential Equation (ODE) model to obtain an increase rate of the pollutant concentration output by the ODE model.

[0041] In some other embodiments, the step 101 can further comprise: predicting the target pollutant concentration at the conference start time according to the increase rate and a time difference between the current time and the conference start time.

[0042] The step 102 comprises: determining a first operation parameter according to the pollutant parameter and the air quality information.

[0043] In the embodiments of the present application, the first operation parameter is an operation parameter of the air purification device when performing pre-purification before the conference start time.

[0044] In some embodiments, the first operation parameter comprises a fan air volume.

[0045] In some embodiments, when the target pollutant concentration is greater than a preset third concentration threshold, or the current indoor pollutant concentration is greater than an upper limit of a preset first concentration range, an upper limit value of the fan air volume is taken as the first operation parameter.

[0046] In a possible implementation manner, the first concentration range can be a pollutant concentration baseline, and when the target pollutant concentration is greater than an upper limit of the first concentration range, it indicates that the current pollutant concentration is at a high level.

[0047] For example, if the current indoor CO2 concentration is 750 ppm and the first concentration range is 400-600 ppm, the current indoor pollutant concentration is greater than the upper limit of the first concentration range, and the air purification device is increased from the first air volume value to the upper limit of the air volume value.

[0048] In some embodiments, the first air volume value and the first running time length are determined as the first running parameters when the target pollutant concentration is less than or equal to the third concentration threshold and the current indoor pollutant concentration is less than or equal to the upper limit of the first concentration range.

[0049] For example, the first air volume value is 60%-70% of the upper limit of the air volume value, and the first running time length is 10-15 minutes (min).

[0050] In step 103, the first adjustment time is determined according to the conference start time and the preset first time length, and the air purification device is controlled to execute the first running parameters at the first adjustment time.

[0051] In the embodiments of the present application, the first adjustment time is earlier than the conference start time.

[0052] For example, the first time length can be 10 min, the first time length can also be 15 min, and the first time length can also be any value in the range of 10-15 min, which is not limited in the embodiments of the present application.

[0053] For example, the conference start time is 14:00, and the first time length is 15 min, so the first adjustment time is 13:45.

[0054] In some embodiments, step 103 includes: subtracting the first time length from the conference start time to obtain the first adjustment time; and controlling the air purification device to start at the first adjustment time and run for the preset first running time length according to the first running parameters.

[0055] In another possible implementation, the air purification device is started at the first adjustment time and runs according to the first running parameters, so that the current indoor pollutant concentration is lower than the upper limit of the preset first concentration range.

[0056] For example, the first adjustment time is 13:45, the first concentration range is 400-600 ppm, and the air purification device is started at 13:45 and runs at 60%-70% of the upper limit of the air volume value, so that the current indoor pollutant concentration is lower than 600 ppm.

[0057] In step 104, the second running parameters of the air purification device are adjusted according to the conference schedule information or the pollutant parameters.

[0058] In the embodiments of the present application, the second operating parameter is an operating parameter of the air purification device during the conference, that is, the second operating parameter is an operating parameter executed after the start time of the conference.

[0059] In some embodiments, step 104 comprises: adjusting the second operating parameter of the air purification device according to the conference schedule information; or adjusting the second operating parameter of the air purification device according to the pollutant parameter.

[0060] In some embodiments, after step 104, the device control method of the conference room comprises: adjusting the operating parameter of the fresh air system according to the conference schedule information and the pollutant parameter; wherein the operating parameter of the fresh air system comprises: the start-stop state of the fresh air system, the release time and the release frequency of the cold air pulse release.

[0061] In some embodiments, the operating parameter of the air purification device comprises: the fan flow of the air purification device, the fan speed of the air purification device, the working mode of the air purification device, etc.

[0062] In a possible implementation, in the case where the air purification device integrates a negative ion generator, the operating parameter of the air purification device further comprises the working state of the negative ion generator.

[0063] In summary, in the embodiments of the present application, the pollutant parameter of the conference room during the conference is predicted according to the conference schedule information and the air quality information, the first operating parameter is determined according to the conference schedule information or the pollutant parameter, and the air purification device is started to perform pre-purification at the first adjustment time before the start time of the conference, which can optimize the air quality in advance, avoid the pollutant concentration exceeding the standard at the initial stage of the conference, and achieve active purification of the air in the conference room; further, the operating parameter of the air purification device is adjusted according to the conference schedule information and the air quality information, which can dynamically adjust the operating parameter during the conference, achieve active intervention on the air quality, avoid the “brain fog” phenomenon caused by the pollutant concentration exceeding the standard, such as decreased attention and drowsiness, and improve the conference efficiency.

[0064] Figure 2 is a specific step flowchart of a device control method of a conference room provided by the embodiments of the present application, as shown in Figure 2 The method can comprise the following steps.

[0065] Step 201, obtaining the current indoor pollutant concentration, determining the indicator light color and air quality level corresponding to the current pollutant concentration.

[0066] In some embodiments, step 201 comprises: obtaining the current indoor pollutant concentration by the pollutant sensor built in the air purification device.

[0067] Exemplarily, the pollutant is CO2, and the pollutant sensor built in the air purification device can be a non-dispersive infrared (NDIR) CO2 sensor.

[0068] In some embodiments, step 201 can include: determining the indicator light color and the air quality level corresponding to the current pollutant concentration according to the interval in which the current pollutant concentration is located and the correspondence between different intervals and the indicator light color and the air quality level.

[0069] Exemplarily, the current pollutant concentration is the current CO2 concentration, and the correspondence between different intervals and the indicator light color can be: in the case that the current CO2 concentration is less than 800 ppm, the air quality level is excellent, and the indicator light color is green; in the case that the current CO2 concentration is greater than or equal to 800 ppm and less than 1000 ppm, the air quality level is slight pollution, and the indicator light color is yellow; in the case that the current CO2 concentration is greater than 1000 ppm, the air quality level is high-concentration pollution, and the indicator light color is red.

[0070] In some embodiments, before step 201, the device control method of the conference room includes: acquiring conference schedule information and air quality information.

[0071] In a possible implementation, an Application Programming Interface (API) connection is established with the office software through wireless connection, and the conference schedule information is acquired from the office software. The wireless connection can be wireless network communication technology (Wi-Fi) or Bluetooth connection.

[0072] In a possible implementation, the schedule synchronization interface is periodically called at a first time period, and an information acquisition request is sent to the office software; the information acquisition request is used to acquire a list of all meetings scheduled in the conference room on the current day; in the case that the meeting list indicates that there is a meeting arrangement on the current day, the meeting start time, the meeting expected duration and the number of participants of the conference room are determined according to the meeting list.

[0073] Exemplarily, the first time period is one natural day, the schedule synchronization interface is called automatically at 06:00 every day, the information acquisition request is sent to the office software, and the list of all meetings scheduled in the conference room on the current day is acquired. If there is a meeting record, the information analysis stage is entered, and the meeting start time, the meeting expected duration and the number of participants of the conference room are obtained.

[0074] In a possible implementation, when the conference list indicates that there is no conference arrangement on the current day, the air purification device is controlled to operate in a standby mode, and the conference schedule information is periodically polled and updated at a second time period.

[0075] In some embodiments, the air quality information includes: a current indoor pollutant concentration, a current outdoor pollutant concentration, a single-person exhaled pollutant rate, and a fresh air volume. The pollutant can be CO2, PM2.5, TVOC, or the like.

[0076] In a possible implementation, the third-party data interface is called to obtain the current outdoor pollutant concentration, and the single-person exhaled pollutant rate pre-stored in the air purification device is obtained.

[0077] In the embodiments of the present application, the fresh air volume can be the amount of fresh air introduced from the outdoor to the indoor.

[0078] In a possible implementation, when the air purification device is integrated with a fresh air module, the fresh air volume is obtained by measuring the airflow speed in the air duct.

[0079] In another possible implementation, when the air purification device is not integrated with a fresh air module, a fresh air volume query request is sent to a fresh air system, and the fresh air volume fed back by the fresh air system is received.

[0080] In step 202, the indicator light color is displayed through the indicator light built in the air purification device, and the terminal device is outputted with the reminder information.

[0081] The reminder information is used to display the current pollutant concentration and the air quality level.

[0082] In a possible implementation, the terminal device can be a mobile terminal of an administrator or a conference organizer, and the terminal device displays the reminder information in the form of an application (APP).

[0083] In a possible implementation, the indicator light built in the air purification device can be a ring-shaped light-emitting diode (LED) light belt on the top of the air purification device.

[0084] In a possible implementation, when the air quality level is high-concentration pollution, the reminder information is further used to suggest the user to open the window for ventilation.

[0085] By the technical solution, the current pollutant concentration is visually displayed by the color of the indicator light, so that the customer can intuitively feel the change of the current pollutant concentration; meanwhile, the current pollutant concentration and the air quality level are reminded by the reminder information, so that the user can remotely view the air quality of the conference room without going to the site, which is conducive to unified management of multiple conference rooms and improvement of product usability and technological sense.

[0086] In step 203, the increase rate is predicted according to the conference schedule information, the current indoor pollutant concentration and a preset mass conservation formula.

[0087] For example, the mass conservation formula can be a first-order ordinary differential equation based on the mass conservation principle, as shown in the following formula:

[0088] In the formula, C represents the current indoor pollutant concentration, C0 represents the current outdoor pollutant concentration, the units of C and C0 are ppm, V represents the volume of the conference room, the unit of V is cubic meters (m 3 ), q represents the fresh air volume, the unit of q is per minute / cubic meter (m 3 / min), N represents the number of participants, and γ represents the pollutant exhalation rate of a single person, the unit of γ is liters / minute (L / min).

[0089] In some embodiments, step 203 can include: In sub-step 2031, the contribution amount of the participants to the pollutant concentration is predicted according to the number of participants, the pollutant exhalation rate of a single person and the preset volume of the conference room. In sub-step 2032, the difference between the current outdoor pollutant concentration and the current indoor pollutant concentration is calculated to obtain a pollutant concentration difference. In sub-step 2033, the influence amount of fresh air ventilation on the pollutant concentration is predicted according to the pollutant concentration difference, the volume of the conference room and the fresh air volume. In sub-step 2034, the increase rate is predicted according to the contribution amount and the influence amount.

[0090] In the embodiments of the present application, the indoor pollutant mass change rate is the difference between the pollutant input rate and the pollutant output rate, the pollutant input rate can be the contribution amount of the participants to the pollutant concentration, the pollutant output rate can be the influence amount of fresh air ventilation on the pollutant concentration, and the increase rate is the ratio of the indoor pollutant mass change rate to the volume of the conference room.

[0091] In the embodiments of the present application, the unit conversion is used to determine the unit matching of all parameters.

[0092] In a possible implementation manner, the contribution amount = the number of participants x the pollutant exhalation rate of a single person / the volume of the conference room.

[0093] In a possible implementation, the fresh air volume is detected by an air purification device air speed sensor or a third-party fresh air system.

[0094] In a possible implementation, the impact volume = (pollutant concentration difference x fresh air volume) / conference room volume.

[0095] In a possible implementation, the increase rate of the pollutant concentration is the difference between the contribution volume and the impact volume.

[0096] In this way, not only the contribution volume of the participants to the pollutant concentration is considered, but also the impact volume of the fresh air ventilation on the pollutant concentration, and the mass conservation principle is used to improve the accuracy of predicting the increase rate of the pollutant concentration. Further, the increase rate of the pollutant concentration is predicted according to the conference duration and the number of participants, which is beneficial to subsequent dynamic adjustment of the conference room equipment according to the conference duration, the number of participants, and the like.

[0097] Step 204, predicting a target pollutant concentration according to the increase rate, the current indoor pollutant concentration, and the conference start time.

[0098] In some embodiments, a time difference between the current time and the conference start time is calculated; a product of the increase rate and the time difference is calculated to obtain a first product; and the current indoor pollutant concentration and the first product are summed to obtain the target pollutant concentration.

[0099] By applying the mass conservation formula to the linkage control of the conference schedule and the air purifier, the increase rate of the pollutant concentration and the target pollutant concentration are predicted, which not only predicts the speed of the change of the pollutant concentration, but also predicts the target pollutant concentration at the conference start time, thereby reducing the limitation of a single dimension.

[0100] Step 205, determining a first operation parameter according to the pollutant parameter and the air quality information.

[0101] The method of this step has been described in the foregoing step 102, and will not be repeated here.

[0102] In some embodiments, step 205 includes: Sub-step 2051, in a case where the target pollutant concentration is greater than a preset third concentration threshold or the current indoor pollutant concentration is greater than an upper limit of a preset first concentration range, taking an upper limit value of the fan air volume as the first operation parameter.

[0103] In a possible implementation, the third concentration threshold is a pollutant concentration value for risk warning, and the specific value of the third concentration threshold is set according to the conference scene and the health standard.

[0104] Exemplarily, the third concentration threshold value can be 800 ppm.

[0105] In a possible implementation, the first concentration range can be a baseline of the pollutant concentration, and when the target pollutant concentration is greater than the upper limit of the first concentration range, it indicates that the current pollutant concentration is at a high level.

[0106] Exemplarily, if the current indoor CO2 concentration is 750 ppm and the first concentration range is 400-600 ppm, the current indoor pollutant concentration is greater than the upper limit of the first concentration range, and the air purification device is increased from the first air volume value to the upper limit of the air volume value.

[0107] By the above technical solution, the air purification device is started to perform pre-purification at the first adjustment time before the conference start time, and the air volume of the air purification device is dynamically adjusted according to the target pollutant concentration or the current indoor pollutant concentration at the conference start time, which can optimize the air quality in advance, avoid the pollutant concentration exceeding the standard at the initial stage of the conference, and achieve active purification of the air in the conference room.

[0108] In other embodiments, step 205 can further include: Sub-step 2052, in the case that the target pollutant concentration is less than or equal to the third concentration threshold value, and the current indoor pollutant concentration is less than or equal to the upper limit of the first concentration range, the first air volume value and the first running time are taken as the first running parameters.

[0109] In a possible implementation, the first running parameters include the first air volume value and the first running time.

[0110] Exemplarily, the first air volume value is 60%-70% of the upper limit of the air volume, and the first running time is 10-15 min.

[0111] Step 206, determining the first adjustment time according to the conference start time and the first time, and controlling the air purification device to perform the first running parameters at the first adjustment time.

[0112] The method of this step has been described in the foregoing step 103, and will not be repeated here.

[0113] In a possible implementation, the first adjustment time is obtained by subtracting the preset first time from the conference start time.

[0114] In some embodiments, step 206 can include: controlling the air purification device to start at the first adjustment time and run at the upper limit of the air volume at the first adjustment time.

[0115] For example, the conference starting time is 14:00, the first time length is 15 min, the first adjustment time is 13:45, and the air purification device starts pre-purification at 13:45 and controls the air purification device to operate according to the upper limit value of the air volume.

[0116] In a possible implementation, the air purification device is controlled to start at the first adjustment time and operate according to the upper limit value of the air volume until the current indoor pollutant concentration of the conference room is less than or equal to the preset safety threshold.

[0117] For example, the safety threshold is 600 ppm, and the CO2 concentration in the conference room is reduced to less than or equal to 600 ppm to avoid entering a high-concentration environment as soon as the conference starts.

[0118] In other embodiments, step 206 can further include: controlling the air purification device to start at the first adjustment time and operate according to the first air volume value and the first operation time length at the first adjustment time.

[0119] Through the above technical solution, compared with starting pre-purification at a fixed time and fixed parameters, the air fan volume of the air purification device can be dynamically adjusted according to the target pollutant concentration at the conference starting time or the current indoor pollutant concentration, which not only avoids the situation that the pollutant concentration exceeds the standard at the initial stage of the conference due to insufficient air volume, but also reduces the waste of energy consumption of the air purification device caused by fixedly using high air volume.

[0120] It should be noted that after step 206, step 207 can be performed, or step 208 can be performed.

[0121] Step 207: adjusting the air fan volume of the air purification device and adjusting the working state of the negative ion generator according to the current indoor pollutant concentration.

[0122] In some embodiments, the air purification device includes a main control unit, an NDIR type CO2 sensor, an adjustable speed fan, and an ion generator; wherein the main control unit is configured to predict the CO2 concentration at the conference starting time according to the current CO2 concentration detected by the NDIR type CO2 sensor, and adjust the air fan volume and the working state of the negative ion generator according to the CO2 concentration at the conference starting time.

[0123] In some embodiments, step 207 can include: Sub-step 2071: increasing the air fan volume in a case where the current indoor pollutant concentration is greater than or equal to a preset first concentration threshold. Sub-step 2072: switching the working state of the negative ion generator from the off state to the start state.

[0124] In the embodiments of this application, the first concentration threshold can be 750 ppm, the first concentration threshold can be 800 ppm, or other values, which are not limited in this application.

[0125] In one possible implementation, if the current indoor pollutant concentration is greater than or equal to a preset first concentration threshold, the fan airflow is increased to a second airflow value.

[0126] For example, the second air volume value can be 85%–90% of the upper limit of air volume.

[0127] In one possible implementation, when the current indoor pollutant concentration is greater than or equal to a preset first concentration threshold, the fan airflow is increased and the air guide plate motor integrated into the air purification equipment is used to drive the air guide plate to oscillate periodically to enhance air turbulence.

[0128] In another possible implementation, if the current indoor pollutant concentration is greater than or equal to a preset first concentration threshold, the air volume is increased at a preset rate.

[0129] For example, a stepped speed increase can be adopted, with the preset speed increase being 10% per minute to increase the upper limit of air volume, to avoid sudden noise increases caused by sudden changes in air volume and to ensure the comfort of the meeting.

[0130] In one possible implementation, switching the operating state of the negative ion generator from the off state to the on state includes: controlling the negative ion generator to start and release negative ions within a preset second concentration range.

[0131] For example, the preset second concentration range could be 1×10 6 ~5×10 6 pcs / cm³

[0132] It is understandable that negative ions cannot directly reduce CO2 concentration, but they can combine with suspended particulate matter such as dust and droplets in the air, causing the suspended particulate matter to become charged and settle, thus reducing airborne particulate matter. In other words, negative ions can improve the sense of air transparency and alleviate the stuffiness caused by high CO2 concentration among participants.

[0133] In some embodiments, after sub-step 2072, the equipment control method for the conference room may further include: changing the color of the control indicator light from green to yellow to indicate a decline in air quality; and pushing a first text reminder message to the APP of the terminal device. For example, the first text reminder message may be "High CO2 concentration detected, entering wakefulness mode".

[0134] In some other embodiments, after sub-step 2072, the equipment control method for the conference room may further include: sending a first control command to the fresh air system in the conference room when the current indoor pollutant concentration is greater than or equal to a preset first concentration threshold; the first control command is used to control the fresh air system to start.

[0135] By employing the aforementioned technical solution, when the current indoor pollutant concentration is greater than or equal to a preset first concentration threshold, increasing the airflow to enhance purification intensity not only reduces the rate of increase in pollutant concentration but also avoids high power consumption throughout the day, thus reducing equipment energy consumption. Further reducing pollution, the negative ion generator is activated, using negative ions to improve the air quality in the meeting room, alleviating the stuffiness experienced by attendees due to the high indoor pollutant concentration and enhancing meeting comfort.

[0136] In some embodiments, after sub-step 2072, the above-mentioned equipment control method for the conference room may further include: Sub-step 2073: If the current indoor pollutant concentration is greater than or equal to the preset second concentration threshold, send a first control command to the fresh air system in the conference room; Sub-step 2074: Calculate the duration of the meeting based on the meeting start time and the current time; Sub-step 2075: If the duration of the meeting exceeds the preset second duration, send a second control command to the fresh air system.

[0137] It should be noted that, in the embodiments of this application, sub-step 2073 can be executed after sub-step 2072, and sub-steps 2074 to 2075 can also be executed after sub-step 2072, and sub-steps 2073 to 2075 can also be executed after sub-step 2072.

[0138] The first control command is used to control the start of the fresh air system.

[0139] In one possible implementation, the first control command is used to control the fresh air system to start and execute specified operating parameters.

[0140] For example, the main control unit sends the first control command to the fresh air system controller through a preset communication protocol; after receiving the command, the fresh air system controller immediately starts and operates according to the specified operating parameters, forming a collaborative purification with the air purification equipment to improve the sense of air permeability and stimulate brain awakening.

[0141] In the embodiments of this application, the second concentration threshold may be the same as the first concentration threshold, or the second concentration threshold may be greater than the first concentration threshold.

[0142] In some embodiments, after sub-step 2073, the equipment control method for the conference room further includes: outputting early warning information to the terminal device; wherein the early warning information is used to remind the user that the concentration of the target pollutant is greater than or equal to a second concentration threshold, and to remind the user to open the window for ventilation.

[0143] In one possible implementation, the estimated meeting duration is obtained by subtracting the meeting's end time from its start time.

[0144] In this embodiment, the second control command is used to control the fresh air system to release cold air pulses according to the third operating parameters.

[0145] For example, the second duration could be 45 minutes. If a meeting ends at 14:00 and starts at 15:30, and the meeting is expected to last 90 minutes, and 90 minutes is longer than the second duration, a second control command is sent to the fresh air system.

[0146] In one possible implementation, the third operating parameter includes the release frequency and release time of the cold air pulse corresponding to the fresh air system. The release time is later than the start time of the meeting.

[0147] In one possible implementation, the cold air pulse can be cold air with an outlet temperature lower than the current room temperature and a preset pulse duration. For example, the cold air pulse can be cold air with an outlet temperature 2 to 3°C lower than the current room temperature and a duration of 60 seconds.

[0148] For example, the release time is 45 minutes after the start of the meeting, and the release frequency is 15 minutes. The second control command is used to release a 60-second cold air pulse every 15 minutes after the start of the meeting. The sudden drop in perceived temperature can activate the sympathetic nervous system and enhance alertness. In this way, short-term cold stimulation can increase the power of beta waves in the brain by more than 15%, thereby stimulating the participants' sense of body temperature, breaking the physiological inertia of sitting still, preventing drowsiness, and significantly improving attention.

[0149] In some embodiments, after sub-step 2075, the equipment control method for the conference room may further include: changing the color of the control indicator light to blue and flashing it at a preset frequency to indicate that the cooling pulse has been released; and pushing a second text reminder message to the APP of the terminal device. For example, the second text reminder message may be "Invigorating fan activated, air disturbance mode has been entered".

[0150] In some embodiments, in response to a user manually turning off the refreshing air function via a mobile app or panel button, the sending of a second control command to the fresh air system is stopped.

[0151] In some embodiments, the equipment control method for the conference room described above may further include: calculating the duration of the conference based on the conference start time and the current time; If the duration of the meeting exceeds the preset second duration, a second control command is sent to the fresh air system.

[0152] Compared to the existing control logic that remains at the "pollution control" level, the above technical solution, when the current indoor pollutant concentration is greater than or equal to the preset second concentration threshold, can link other equipment and the fresh air system in the conference room to not only improve air quality by increasing air volume and air flow, but also provide sensory stimulation through cold air pulses, forming a dual wake-up mechanism. This effectively prevents cognitive fatigue during long meetings and achieves the core goal of "preventing drowsiness".

[0153] In some embodiments, prior to sub-step 2075, the equipment control method for the conference room may further include: Sub-step A1: If the expected duration of the meeting exceeds the preset fourth duration and the rate of increase of pollutants is greater than the preset rate threshold, increase the release frequency of the cold air pulse corresponding to the fresh air system to obtain a new release frequency. Sub-step A2: Shorten the time interval between the meeting start time and the release time to obtain a new release time; Sub-step A3: Determine the third operating parameter based on the new release frequency and the new release time.

[0154] In this embodiment of the application, the release time is the release time of the first cold air pulse.

[0155] In the embodiments of this application, the fourth duration represents the physiological limit of human sustained focus. For example, the fourth duration can be 60 minutes, 45 minutes, or any value between 45 minutes and 60 minutes.

[0156] In the embodiments of this application, a pollutant increase rate greater than a preset rate threshold indicates that the rate of increase is in a significant growth range. For example, the preset rate threshold is 20 parts per million concentration per minute (ppm / min).

[0157] Understandably, when a meeting is expected to last longer than four hours, participants are prone to physiological inertia due to prolonged sitting and sustained strain on their attention, leading to drowsiness and inattentiveness. Similarly, if the rate of increase in pollutants exceeds a preset threshold, it means that the rate at which participants exhale pollutants far exceeds the dilution rate of the fresh air system and air purification equipment, causing a rapid accumulation of indoor pollutant concentrations and further exacerbating participant fatigue. Therefore, when meetings are long and pollutant concentrations rise rapidly, more frequent cold air pulses are needed to activate enhanced intervention.

[0158] In one possible implementation, the release frequency of the cold air pulse is shortened from once every 15 minutes to once every 8-10 minutes to obtain a new release frequency; the release time of the first cold air pulse is advanced to obtain a new release time.

[0159] For example, if a meeting starts at 14:00 and is expected to end at 15:30, the system originally planned to first activate the "air disturbance mode" 45 minutes after the meeting starts (i.e., 14:45), and then activate it every 15 minutes. However, due to the higher risk, the system will activate it earlier at 14:30. In addition, the activation frequency will be increased from once every 15 minutes to once every 10 minutes, releasing cold air pulses to achieve pre-awakening intervention for cognitive fatigue.

[0160] Through the above technical solutions, when the meeting lasts for a long time and the pollution concentration rises rapidly, enhanced intervention is activated to increase the release frequency of cold air pulses and release them in advance, thereby optimizing operating parameters in advance. This helps to promote indoor air convection, slow down the rate of increase in pollutant concentration, and effectively prevent cognitive fatigue during long meetings.

[0161] Step 208: Adjust the fan speed of the air purifier according to the end time of the meeting.

[0162] In some embodiments, an infrared sensor determines whether the meeting has ended based on the meeting's end time. If the meeting has ended, the fan speed of the air purifier is reduced to avoid unnecessary high-load operation of the equipment after the meeting. For example, the fan speed is reduced in stages at a preset rate, rather than being shut down abruptly, to avoid equipment damage and noise caused by sudden changes in air speed.

[0163] The above technical solution adjusts the operating parameters of the air purification equipment according to the end time of the meeting or the current indoor pollutant concentration, realizing dynamic adjustment of the operating parameters. The control logic is simple and easy to implement, can be built into existing air purifiers, has good software and hardware compatibility, and low deployment cost.

[0164] In some embodiments, step 208 may include: Sub-step 2081: After the meeting ends, detect the indoor activity status of the conference room using an infrared sensor; Sub-step 2082: If no indoor activity is detected within the preset third time period, reduce the fan speed at a preset rate.

[0165] In this embodiment of the application, the indoor activity status can be the activities of people in the conference room.

[0166] In one possible implementation, after the meeting ends, infrared sensors periodically detect infrared radiation emitted by the human body to determine whether there is any indoor activity in the meeting room, including people moving or staying in one place.

[0167] For example, an infrared sensor scans the conference room every 5 to 10 seconds to ensure timely status detection.

[0168] In one possible implementation, after sub-step 2081, the equipment control method for the conference room may include: maintaining the current operating parameters to ensure the temporary use needs of personnel if indoor activity is detected within a preset third time period.

[0169] For example, the third duration is 10 to 15 minutes.

[0170] In one possible implementation, if no indoor activity is detected within a preset third time period, the maximum wind speed is reduced by 20% per minute until a silent mode is entered.

[0171] In another possible implementation, if no indoor activity is detected within a preset third time period, the fan gradually reduces its speed and runs for 5 minutes to clean the exhaust gas.

[0172] In one possible implementation, after sub-step 2082, the equipment control method for the aforementioned conference room may include: monitoring the current indoor pollutant concentration; if the conference schedule information indicates that there are no new meetings within a fifth duration, controlling the air purification equipment to shut down or switch to a deep standby mode. For example, the fifth duration could be 30 minutes.

[0173] The above technical solution detects indoor activity after the meeting ends. If no indoor activity is detected within a preset third time period, the fan speed is reduced at a preset rate, avoiding noise from sudden speed reduction and reducing the energy consumption of the equipment.

[0174] In summary, in this embodiment, meeting schedule information is incorporated into air purification control. The control logic can be built into existing air purifiers, resulting in good hardware and software compatibility and low deployment costs. Secondly, the mass conservation formula is applied to the linkage control between the meeting schedule and the air purifier, predicting the rate of increase in pollutant concentration and the target pollutant concentration. This not only predicts the speed of pollutant concentration changes but also the target pollutant concentration at the start of the meeting, reducing the limitations of a single dimension and facilitating pre-purification control before the meeting. Finally, it supports schedule synchronization across multiple office platforms and provides visualized feedback on the operating status, enhancing product usability and technological appeal.

[0175] Figure 3This is a flowchart of another equipment control method for a conference room provided in an embodiment of this application, as follows: Figure 3 As shown, taking CO2 as an example, the method may include the following steps.

[0176] Step 301: Listen to the company's calendar time to obtain meeting schedule information.

[0177] Step 302: Predict the rate of increase in CO2 and the trend of air pollution deterioration.

[0178] Step 303: Start the pre-purification mode 15 to 30 minutes in advance.

[0179] Step 304: Start automatic mode.

[0180] The automatic mode is used to adjust the wind speed and air volume based on the real-time monitoring of particulate matter and gaseous pollutant concentrations to maintain clean air.

[0181] Step 305: Monitor CO2 concentration data in real time after the meeting begins.

[0182] Step 306: Determine if the CO2 concentration is greater than 800 ppm; if yes, proceed to step 308; if no, proceed to step 307.

[0183] Step 307: Maintain the current mode.

[0184] Step 308: Activate the wakefulness mode.

[0185] The "Awake Mode" is used to control the air purifier to operate at high speed and release negative ions, which in turn activates the fresh air system.

[0186] Step 309: Determine if the preset meeting duration exceeds 45 minutes; if yes, proceed to step 310; if no, return to step 308.

[0187] Step 310: Activate the air disturbance mode.

[0188] Among them, the air disturbance mode is used to link the fresh air system to release cold air pulses to stimulate a feeling of wakefulness.

[0189] Step 311: Determine if the meeting has ended; if yes, the process ends; if no, return to step 310.

[0190] In summary, the present application's embodiments incorporate meeting schedule information into air purification control, with "preventing drowsiness" as the core objective, promoting the transformation of air purification equipment from traditional environmental governance to proactive health protection, demonstrating significant innovation and market competitiveness.
