DETAILED DESCRIPTION

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0044] See also Figures 1 to 7The present invention provides a whole-house intelligent oxygen supply system including a concentration monitoring module 1, a concentration analysis module 2, a human trace monitoring module 3, a main control module 4 and an oxygen control module 5, wherein the oxygen control module 5 is connected to the main control module 4, the human trace monitoring module 3 is connected to the main control module 4, the concentration monitoring module 1 is connected to the concentration analysis module 2, the concentration analysis module 2 is connected to the main control module 4, and the main control module 4 is connected to the concentration monitoring module 1;

[0045] The concentration monitoring module 1 is used to monitor the oxygen concentration, carbon dioxide concentration and combustible gas concentration in a specified area;

[0046] The concentration analysis module 2 is used to analyze the acquired oxygen concentration, carbon dioxide concentration and combustible gas concentration data;

[0047] The human footprint monitoring module 3 is used to monitor the activities of people in a designated area;

[0048] The main control module 4 controls the corresponding modules based on the received data results;

[0049] The oxygen control module 5 regulates the oxygen concentration in the designated area based on the received instructions.

[0050] Specifically, the concentration monitoring module 1 monitors the oxygen concentration in the environment of the specified area, and then the concentration analysis module 2 analyzes the monitoring data of the concentration monitoring module 1. Thereafter, the main control module 4 generates and outputs corresponding instructions based on the analysis results of the concentration analysis module 2. Finally, the oxygen control module 5 completes the control of the corresponding equipment by receiving and analyzing the instructions issued by the main control module 4, thereby realizing the adjustment of the oxygen concentration. Among them, the main control module 4 has a human-machine operation interface, can be connected to the Internet, and can remotely, automatically, timed or manually control the oxygen concentration in the room. At the same time, the concentration monitoring module 1 adopts a multi-probe monitoring instrument, which can monitor the oxygen concentration, carbon dioxide concentration and combustible gas concentration in the specified area in real time.

[0051] For further information, see Figure 2 , the concentration monitoring module 1 includes a data acquisition submodule 11 and a data processing submodule 12, the data acquisition submodule 11 is connected to the data processing submodule 12, and is connected to the main control module 4; the data processing submodule 12 is connected to the concentration analysis module 2;

[0052] The data acquisition submodule 11 is used to obtain the real-time oxygen concentration, carbon dioxide concentration and combustible gas concentration in the specified area;

[0053] The data processing submodule 12 is used to classify and process the acquired real-time oxygen concentration, carbon dioxide concentration and combustible gas concentration according to a set time period, and generate corresponding gas concentration comparison data.

[0054] In this embodiment, the data acquisition submodule 11 mainly completes the concentration monitoring of various gases in the specified area through a multi-probe gas concentration monitor. The corresponding multi-probe gas concentration monitor can be installed according to the actual use needs of the user. When installing, it is necessary to select a suitable installation position according to the scope of the monitoring area, so as to be able to more accurately monitor the concentration of various gases in the area;

[0055] The data processing submodule 12 is mainly used to process and analyze the real-time oxygen concentration obtained by the data acquisition submodule 11. Since the gas concentration in the entire space is changing all the time, the average value of the gas concentration within the specified time can be used to more accurately judge the concentration status of various gases in the specified area. As for the selection of time, it can be set according to actual usage. The set time should not be too long, and it is best to keep it within one minute. When the set time is too long, the overall control accuracy and efficiency will be too low. However, if the set time is too short, the data processing volume of the entire system will be large. Therefore, the time setting should be kept within an appropriate range.

[0056] For further information, see Figure 3 , the concentration analysis module 2 includes a range setting submodule 21 and a judgment submodule 22, the range setting submodule 21 is connected to the judgment submodule 22; the judgment submodule 22 is connected to the concentration monitoring module 1, and is connected to the main control module 4;

[0057] The range setting submodule 21 is used to set the normal oxygen concentration range, carbon dioxide concentration range and combustible gas concentration range in advance;

[0058] The judgment submodule 22 analyzes and judges the specified gas concentration comparison data based on the set normal oxygen concentration range, carbon dioxide concentration range and combustible gas concentration range.

[0059] For further information, see Figure 7, the judgment submodule 22 includes a mobilization instruction unit 221, a concentration change analysis unit 222 and an instruction integration issuing unit 223, the mobilization instruction unit 221 is connected to the range setting submodule 21, and is connected to the concentration monitoring module 1; the concentration change analysis unit 222 is connected to the mobilization instruction unit 221, and is connected to the instruction integration issuing unit 223, and is connected to the main control module 4; the instruction integration issuing unit 223 is connected to the mobilization instruction unit 221, and is connected to the main control module 4;

[0060] The adjustment instruction unit 221 is used to determine whether the gas concentration comparison data is within a normal concentration range, and generate an adjustment instruction based on the determination result;

[0061] The concentration change analysis unit 222 is used to calculate the change of the oxygen concentration comparison data within a set time range and generate a frequency modulation instruction based on the change;

[0062] The instruction integration and issuing unit 223 generates a control instruction based on the acquired maneuvering instruction and the frequency modulation instruction.

[0063] In this embodiment, the range setting submodule 21 is used for the user to set the adjustment range of various gases in advance, and the adjustment instruction unit 221 in the judgment submodule 22 compares the obtained gas concentration comparison data with the set control range to determine whether the obtained gas concentration comparison data is within the set control range. When the oxygen concentration in the gas concentration comparison data is lower than the set control range, it can be determined that the oxygen concentration inside the designated area is low, and the corresponding adjustment instruction can be generated. According to the generated adjustment instruction, the entire control system can be activated to adjust the oxygen concentration inside the designated area.

[0064] The concentration change analysis unit 222 in the judgment submodule 22 is mainly used to analyze and judge the change of oxygen according to the oxygen concentration comparison data obtained in different time periods, for example, the oxygen consumption rate is calculated according to the change amplitude of the oxygen concentration comparison data within the specified time, and then the instruction integration and issuance unit 223 can adjust the output power of oxygen by generating the frequency modulation instruction according to the oxygen consumption rate analyzed by the concentration change analysis unit 222, so as to be able to appropriately adjust the output of oxygen according to the oxygen consumption in the area, thereby better ensuring the stability of the oxygen concentration in the specified area. It should be noted that if the mobilization instruction issued by the mobilization instruction unit 221 shows that there is no need to adjust the oxygen concentration, that is, the monitored oxygen concentration data meets the set oxygen concentration range, then the instruction integration and issuance unit 223 will not integrate the control instruction issued by the frequency modulation instruction. Only when the mobilization instruction issued by the mobilization instruction unit 221 shows that regulation is required, the instruction integration and issuance unit 223 will integrate a series of instructions and issue the final control instruction;

[0065] It should be noted that the present invention also monitors the carbon dioxide concentration and the combustible gas concentration in real time, the oxygen concentration detection signal is used to control the oxygen content in the room, the carbon dioxide concentration detection is used to link the ventilation equipment, and ventilation will be carried out when the carbon dioxide concentration is too high. The combustible gas concentration detection is to prevent indoor gas leakage. When the indoor combustible gas concentration detection exceeds the preset range, an instruction to stop oxygen delivery will be directly issued, because when the indoor combustible gas concentration is high, the oxygen concentration will be relatively low. According to the above judgment, an oxygen delivery instruction will be issued, but oxygen and excessive combustible gas are easy to form a mixed explosive gas, which is easy to deflagrate or explode when encountering an ignition source. Therefore, when it is detected that the combustible gas concentration exceeds the standard, the oxygen delivery will be stopped immediately. At the same time, based on the monitoring results of the combustible gas concentration, it can also cooperate with the corresponding fire alarm installed in the room to issue an early warning to avoid fire and the like. For the monitoring of carbon dioxide concentration, when it is detected that the carbon dioxide concentration exceeds the standard, the corresponding ventilation will be carried out first by sending the control quality. When the carbon dioxide concentration continues to exceed the standard, the oxygen supply will be stopped. Because the carbon dioxide concentration continues to exceed the standard, a fire may have occurred. If oxygen is continued to be supplied, the spread of the fire will be accelerated.

[0066] For further information, see Figure 4 The human trace monitoring module 3 includes a personnel sensing submodule 31 and a marking submodule 32, wherein the personnel sensing submodule 31 is connected to the marking submodule 32; and the marking submodule 32 is connected to the main control module 4;

[0067] The personnel sensing submodule 31 is used to sense the entry of personnel into a designated area;

[0068] The marking submodule 32 marks the sensed personnel entry data based on the actual installation position of the sensing device.

[0069] In this embodiment, the personnel sensing submodule 31 mainly uses an infrared temperature sensing mechanism to judge the situation of personnel entering the area. The user can install multiple oxygen concentration monitoring devices and infrared temperature sensing mechanisms according to the actual divided area situation. It should be noted that the corresponding infrared temperature sensing mechanism corresponds to the oxygen concentration monitoring device provided. The marking submodule 32 is used to mark the installation position of the oxygen concentration monitoring device on the sensing signal emitted by the corresponding infrared temperature sensing mechanism. In this way, when the main control module 4 receives the sensing signal emitted by the infrared temperature sensing mechanism, it can quickly control the oxygen concentration monitoring device at the specified position through the position mark;

[0070] The above-mentioned entire oxygen control system is based on the oxygen concentration monitoring data of the designated area. The oxygen concentration monitoring equipment in the designated area can be automatically activated through the personnel sensing submodule 31 and the marking submodule 32. When a person is detected to enter the corresponding area, if the oxygen concentration monitoring equipment in the corresponding area is in the off state, the main control module 4 can activate the oxygen concentration monitoring equipment at the corresponding position through the received sensing signal with the designated position information, thereby activating the oxygen control system in the corresponding area.

[0071] For further information, see Figure 5 The main control module 4 includes an oxygen output control submodule 41 and a system operation control submodule 42. The oxygen output control submodule 41 is connected to the oxygen control module 5 and to the concentration analysis module 2; the system operation control submodule 42 is connected to the concentration monitoring module 1, to the concentration analysis module 2, and to the human footprint monitoring module 3;

[0072] The oxygen output control submodule 41 generates and outputs corresponding oxygen delivery instructions based on the analysis results of the gas concentration comparison data;

[0073] The system operation control submodule 42 controls the concentration monitoring module 1 based on the oxygen concentration data analysis result combined with the monitoring of personnel activities.

[0074] For further information, see Figure 6 , the oxygen control module 5 includes an instruction analysis submodule 51 and a work execution submodule 52, the instruction analysis submodule 51 is connected to the main control module 4; the work execution submodule 52 is connected to the instruction analysis submodule 51;

[0075] The instruction analysis submodule 51 is used to receive and analyze the issued oxygen delivery instruction;

[0076] The work execution submodule 52 controls the oxygen generating device to generate and output oxygen based on the analysis result of the oxygen delivery instruction.

[0077] In this embodiment, the oxygen output control submodule 41 in the main control module 4 is mainly used to receive the control instruction issued by the instruction integration and issuance unit 223, and then perform signal conversion processing on the received control instruction to generate a corresponding control instruction signal and send it to the instruction analysis submodule 51 of the oxygen control module 5. The instruction analysis submodule 51 analyzes the control instruction signal to further determine the output position, output range and corresponding output power of oxygen, and finally realizes the oxygen concentration control of the specified area through the work execution submodule 52;

[0078] The work execution submodule 52 is composed of a corresponding oxygen source and a transmission pipeline, etc. The oxygen source can be an oxygen concentrator, bottled oxygen, and a combination thereof. If the oxygen source uses an oxygen concentrator, the local air humidity must also be considered. When using bottled oxygen, automatic switching, a pressure reducing device, etc. can be set. The size of the gas source is calculated according to the user's demand, and the supply of the gas source is calculated according to the following formula.

[0079] Gas unit flow calculation formula:

[0080] Q--Calculated flow rate of gas source (L / min);

[0081] Qa--Rated flow rate at the terminal (L / min), usually 10L / min;

[0082] Qb--Calculated average flow rate at the terminal (L / min), usually 6L / min;

[0083] n-------The number of oxygen supply units;

[0084] η------Simultaneous use coefficient, usually 75%.

[0085] Total oxygen flow = sum of flow rates of each gas unit * 0.06m 3 / h,

[0086] As for the corresponding transmission pipeline, the diameter of the pipe needs to be calculated according to the user's usage. The calculation method can refer to the following formula, but the minimum diameter of the main pipe should not be less than φ8mm, and the minimum diameter of the branch pipe should not be less than φ6mm: The material of the pipeline can be stainless steel pipe or copper pipe above grade 304.

[0087] Pipe diameter calculation formula:

[0088] d--pipe diameter mm (inner diameter);

[0089] Q--Flow rate m 3 / h;

[0090] V--flow velocity m / s, usually 10m / s;

[0091] The oxygen output control submodule 41 in the main control module 4 adopts an intelligent control system, which is composed of a control host, a display module and a gas circuit control module. It can automatically start and stop the oxygen source through the automatic monitoring and analysis of the oxygen concentration by the concentration monitoring module 1 and the concentration analysis module 2. At the same time, the entire control system can also be provided with a corresponding remote operation module to support remote monitoring and control by mobile phone APP, so as to build a whole-house intelligent oxygen supply;

[0092] The system operation control submodule 42 mainly starts the monitoring equipment in the designated area by receiving and analyzing the sensing signal of the human footprint monitoring module 3, thereby activating the control system of the corresponding area. At the same time, the system operation control submodule 42 can also shut down the control system of the corresponding area by analyzing the concentration change analysis unit 222 calculated by the concentration change analysis unit 222. When the concentration change analysis unit 222 calculates that the oxygen concentration consumption rate remains at a small value for a long time, the control monitoring equipment can be stopped from monitoring. Because when the designated area is in an unmanned state, the oxygen concentration consumption rate in the area will approach zero, especially in the current residential areas. In order to improve the living environment, tenants still Green plants will be cultivated indoors, which will result in no large oxygen consumption inside the entire house when no one is using it. In this way, the entire oxygen supply system naturally does not need to be adjusted, and the entire system can be controlled to be shut down to avoid unnecessary energy consumption. Moreover, when people go out, especially for a long time, the entire house will be in a sealed state with doors and windows closed. Therefore, the internal oxygen concentration will not be frequently exchanged with the external environment, so the internal oxygen consumption will also be maintained in a small numerical range. In this way, it can be judged through the analysis structure of the oxygen consumption that no one lives in the residential area, and then the oxygen supply system can be shut down. When the person re-enters the designated area, the entire oxygen supply system can be activated through the human footprint monitoring module 3.

[0093] See also Figure 8 A whole-house intelligent oxygen supply method, using the whole-house intelligent oxygen supply system, comprises the following steps:

[0094] S1: Monitor the oxygen concentration in the environment of the designated area through the concentration monitoring module 1;

[0095] Specifically, the concentration monitoring module 1 includes a data acquisition submodule 11 and a data processing submodule 12. The data acquisition submodule 11 mainly completes the oxygen concentration monitoring inside the specified area through the oxygen concentration monitor. The corresponding oxygen concentration monitor can be installed according to the actual use requirements of the user. When installing, it is necessary to select a suitable installation position according to the scope of the monitoring area, so as to be able to more accurately monitor the oxygen concentration in the area;

[0096] The data processing submodule 12 is mainly used to process and analyze the real-time oxygen concentration obtained by the data acquisition submodule 11. Since the oxygen concentration in the entire space is changing all the time, the oxygen concentration state in the specified area can be judged more accurately by adopting the average value of the oxygen concentration within the specified time. As for the selection of time, it can be set according to actual usage. The set time should not be too long, and it is best to keep it within one minute. When the set time is too long, the overall control accuracy and efficiency will be too low. However, if the set time is too short, the data processing volume of the entire system will be large. Therefore, the time setting should be kept within an appropriate range.

[0097] S2: Then the concentration analysis module 2 analyzes the monitoring data of the concentration monitoring module 1;

[0098] Specifically, the concentration analysis module 2 includes a range setting submodule 21 and a judgment submodule 22, and the judgment submodule 22 includes a mobilization instruction unit 221, a concentration change analysis unit 222 and an instruction integration issuing unit 223. The range setting submodule 21 is used for the user to set the oxygen adjustment range in advance, and the mobilization instruction unit 221 in the judgment submodule 22 compares the obtained oxygen concentration comparison data with the set control range to determine whether the obtained oxygen concentration comparison data is within the set control range. When the oxygen concentration comparison data is lower than the set control range, it can be determined that the oxygen concentration inside the designated area is low, and the corresponding mobilization instruction can be generated. According to the generated mobilization instruction, the entire control system can be activated to adjust the oxygen concentration inside the designated area.

[0099] The concentration change analysis unit 222 in the judgment submodule 22 is mainly used to analyze and judge the change of oxygen according to the oxygen concentration comparison data obtained in different time periods, for example, the oxygen consumption rate is calculated according to the change amplitude of the oxygen concentration comparison data within the specified time, and then the instruction integration and issuance unit 223 can adjust the output power of oxygen by generating the frequency modulation instruction according to the oxygen consumption rate analyzed by the concentration change analysis unit 222, so as to be able to appropriately adjust the output of oxygen according to the oxygen consumption in the area, thereby better ensuring the stability of the oxygen concentration in the specified area. It should be noted that if the mobilization instruction issued by the mobilization instruction unit 221 shows that there is no need to adjust the oxygen concentration, that is, the monitored oxygen concentration data meets the set oxygen concentration range, then the instruction integration and issuance unit 223 will not integrate the control instruction issued by the frequency modulation instruction. Only when the mobilization instruction issued by the mobilization instruction unit 221 shows that regulation is required, the instruction integration and issuance unit 223 will integrate a series of instructions and issue the final control instruction.

[0100] S3: the main control module 4 controls the concentration monitoring module 1 according to the monitoring result of the human footprint monitoring module 3 and the analysis result of the concentration analysis module 2;

[0101] S4: the main control module 4 generates corresponding instructions by analyzing and judging the analysis results of the concentration analysis module 2;

[0102] S5: The oxygen control module 5 controls the corresponding equipment by receiving and analyzing the instructions sent by the main control module 4, thereby adjusting the oxygen concentration.

[0103] Specifically, the human trace monitoring module 3 includes a personnel sensing submodule 31 and a marking submodule 32. The personnel sensing submodule 31 mainly uses an infrared temperature sensing mechanism to judge the situation of people entering the area. The user can install multiple oxygen concentration monitoring devices and infrared temperature sensing mechanisms according to the actual divided area situation. It should be noted that the corresponding infrared temperature sensing mechanism corresponds to the oxygen concentration monitoring device provided one by one. The marking submodule 32 is used to mark the installation position of the oxygen concentration monitoring device on the sensing signal emitted by the corresponding infrared temperature sensing mechanism. In this way, when the main control module 4 receives the sensing signal emitted by the infrared temperature sensing mechanism, it can quickly control the oxygen concentration monitoring device at the specified position through the position mark;

[0104] The above-mentioned entire oxygen control system is based on the oxygen concentration monitoring data of the designated area. The oxygen concentration monitoring equipment in the designated area can be automatically activated through the personnel sensing submodule 31 and the marking submodule 32. When a person is detected to enter the corresponding area, if the oxygen concentration monitoring equipment in the corresponding area is in the off state, the main control module 4 can activate the oxygen concentration monitoring equipment at the corresponding position through the received sensing signal with the designated position information, thereby activating the oxygen control system in the corresponding area.

[0105] The main control module 4 includes an oxygen output control submodule 41 and a system operation control submodule 42. The oxygen output control submodule 41 in the main control module 4 is mainly used to receive the control instruction issued by the instruction integration and issuance unit 223, and then perform signal conversion processing on the received control instruction to generate a corresponding control instruction signal and send it to the instruction analysis submodule 51 of the oxygen control module 5. The instruction analysis submodule 51 analyzes the control instruction signal to further determine the output position, output range and corresponding output power of oxygen, and finally realizes the oxygen concentration control of the specified area through the work execution submodule 52.
