However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following examples, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0036] like Figure 1As shown, the present invention provides a subway integrated air conditioning system, including an air conditioning wind module, an environment and human flow monitoring module and an air duct monitoring module.

[0037] In this embodiment, the air conditioning module is used to control the temperature inside the subway station by adjusting the frequency of the fan inverter and controlling the opening of the air valve, so that the temperature inside the subway station reaches a preset target temperature.

[0038] In this embodiment, the environment and crowd flow monitoring module is used to determine the target temperature according to the environmental parameters of the subway station; the environmental parameters include the temperature outside the subway station, the real-time weather, and the crowd flow or number of people in the station.

[0039] In this embodiment, the air duct monitoring module is used to detect the information of each air duct in the subway station; the air duct information includes the air duct temperature, the air duct flow rate, etc.

[0040] In this embodiment, Figure 2 As shown, the air conditioning module includes a first air duct 1 and a second air duct 2; the first air duct 1 is used to supply air to the inside of the subway station, and the second air duct 2 is used to exhaust air to the inside of the subway station.

[0041] Among them, the first air duct 1 includes a first well 11, a first chamber 12 and a first unit 13; the first well 11 is a fresh air well, which is used to inhale fresh air from the outside of the subway station, and then the fresh air enters the first chamber 12 (fresh air chamber) through the pipe, and finally enters the first unit 13 (air-conditioning unit) through the pipe, and enters the subway station from the air inlet end after temperature control.

[0042] Among them, the second air duct 2 includes a second shaft 21, a second chamber 22 and a second unit 23; the exhaust end of the second unit 23 (exhaust fan unit) sucks in waste air from the inside of the subway station, enters the second chamber 22 (exhaust chamber) through a pipe, and then is discharged from the second shaft 21 (exhaust shaft) to the outside of the subway station through a pipe.

[0043] In this embodiment, a first valve 24 is provided between the second well 21 and the second chamber 22, and a second valve 25 is provided between the first chamber 12 and the second chamber 22; when the first valve 24 is opened and the second valve 25 is closed, the first air duct 1 and the second air duct 2 operate independently; when the first valve 24 is closed and the second valve 25 is opened, waste air can enter the first chamber 12 from the second chamber 22 through the second valve 25 and mix with fresh air.

[0044] In this embodiment, the carbon dioxide concentration in the waste air can be detected by a carbon dioxide concentration detection device, so that the waste air can be directly discharged or partially / fully mixed with fresh air according to the carbon dioxide concentration.

[0045] For example, it switches according to the concentration threshold of carbon dioxide or particulate matter, and directly discharges after exceeding the threshold. The threshold can be set by yourself. When the carbon dioxide concentration is less than 1000ppm, it is comfortable and no exhaust is required, that is, the first valve 24 and the second valve 25 are both closed; when the carbon dioxide concentration is in the range of 1000ppm-1500ppm, the first valve 24 is closed and the second valve 25 is opened, and the waste air can enter the first chamber 12 from the second chamber 22 through the second valve 25 and mix with the fresh air; when the carbon dioxide concentration is greater than 1500ppm, it is determined that the air is relatively turbid under the threshold state, and it is automatically switched to direct exhaust of waste air, that is, the second valve 25 is closed and the first valve 24 is opened.

[0046] In this embodiment, the first unit 13 includes a variable frequency magnetic levitation centrifuge for refrigeration, a filter assembly and an air valve for filtering; wherein the variable frequency magnetic levitation centrifuge has a cop of 6.0, and directly cools the chiller by water cooling or other means. The second unit 23 includes an exhaust fan and an air valve. The first unit 13 and the second unit 23 are pre-installed on the installation template base, and are transported uniformly through the installation template base during transportation. When installed, they are fixed to the machine room through the installation template base, and are modularly designed and transported to facilitate assembly.

[0047] In this embodiment, the environment and crowd flow monitoring module monitors the temperature outside the subway station, the real-time weather, and the flow of people or the number of people in the station, and detects meteorological conditions, etc., and determines the appropriate target temperature for the appropriate temperature under different weather conditions and the flow of people in the station, etc. How to sense the external temperature through devices such as temperature sensors, how to query the real-time weather, and how to detect the flow of people or the number of people are all existing technologies, and will not be elaborated on here.

[0048] In this embodiment, Figure 3 As shown, the environment and human flow monitoring module includes an environment parameter detection unit and a target temperature determination unit.

[0049] The environmental parameter detection unit is used to detect the environmental parameters of the subway station, including internal and external temperatures, real-time weather, and the flow or number of people in the station;

[0050] The target temperature determination unit is preset with a variety of detection control tables or fitting curves (corresponding to different environmental parameters), and obtains the first target temperature according to the environmental parameters.

[0051] That is, in different weather conditions, a control table with different outside temperature-first target temperature is set up to minimize the temperature difference between inside and outside the station while approaching the comfortable temperature. Specifically, it can be obtained based on the historical data statistics of the subway air-conditioning system. The statistical sample can be the adjusted temperature after the flow of people is in the reference area (the flow of people can be 0 or other intervals) and maintained for a certain period of time, and then the average temperature is taken to obtain the first target temperature. Curve fitting can also be performed based on the above table.

[0052] In this embodiment, the environment and human flow monitoring module further includes a region division unit and a temperature update unit.

[0053] The area division unit is used to divide the passenger flow parameters into several areas, and obtain the corresponding offset temperature according to which area of ​​the distribution area the passenger flow in the station falls into.

[0054] The greater the flow of people, the greater the total heat dissipated, and the greater the impact on the overall ambient temperature. The air outlet temperature needs to be further reduced by an offset temperature so that the actual temperature obtained in the station as a whole is more suitable.

[0055] Furthermore, the offset temperatures of different pedestrian flow intervals compared to the reference interval can be directly preset, for example, the offset temperature of area A1 is a1, and the offset temperature of area A2 is a2; they can also be set to different levels in sequence, for example, the offset temperature is -0.5°C for each level increase in pedestrian flow, so that the offset temperature = -0.5*the level difference with the reference interval.

[0056] The temperature updating unit is used to calculate the second target temperature corresponding to each area according to the offset temperature (the second target temperature=the first target temperature+the offset temperature).

[0057] In this embodiment, prediction can also be achieved through machine learning and the frequency of the first unit 13 and the opening of the air valve can be controlled.

[0058] In this embodiment, the environmental human flow monitoring module also includes a carbon dioxide concentration detection unit, which is used to detect the carbon dioxide concentration in the waste air, thereby controlling the waste air (exhaust air) to be directly discharged from the second well 21 or from the second chamber 22 into the first chamber 21 and mixed with fresh air according to the carbon dioxide concentration.

[0059] In this embodiment, the air duct monitoring module is used to monitor the air duct information in the air duct to facilitate risk assessment and maintenance.

[0060] like Figure 4 As shown, the air duct monitoring module includes M temperature and flow detection units (with unique numbers corresponding to the positions), which are evenly distributed in the connecting pipes of the first air duct 1 and the second air duct 2 (which may be located on the upper side of the pipes), and are used to detect temperature and flow, and are numbered {1, 2, 3, ..., i-1, i, i+1, ..., m}.

[0061] In this embodiment, abnormal points can be screened out by comparing the real-time temperatures and flows at different positions in the first air duct 1 and the second air duct 2. The screening work can be a data comparison at a certain interval, or a data curve comparison within a period of time. The abnormal point can be a point where the difference in flow and temperature compared with nearby points exceeds a preset value.

[0062] In this embodiment, the method for screening abnormal location points is:

[0063] A1: M temperature flow detection units are installed in the first air duct 1. Taking temperature as an example, calculate the first difference between the temperature of the first temperature flow detection unit and the temperature of the mth temperature flow detection unit c1 = T1-T m , T1 represents the temperature of the first temperature flow detection unit, T m represents the temperature of the mth temperature flow detection unit;

[0064] If the first difference c1 is less than the first temperature difference threshold α, it means that the temperature difference at both ends of the air duct is within the set range, which is a normal phenomenon; if the first difference c1 is greater than or equal to the first temperature difference threshold α, it means that the air duct or the connection at both ends of the air duct has aging or failure problems.

[0065] A2: Then calculate the temperature T of the i-th temperature flow detection unit i The second difference between the average temperature of two adjacent temperature flow detection units, T i represents the temperature of the ith temperature flow detection unit, T i-1 represents the temperature of the i-1th temperature flow detection unit, T i+1 represents the temperature of the i+1th temperature flow detection unit;

[0066] If the second difference c2 is less than the second temperature difference threshold β, it means that the temperature difference between the corresponding position point of the i-th temperature flow detection unit and the two ends is relatively uniform, which is a normal phenomenon; if the second difference c2 is greater than or equal to the second temperature difference threshold β, it means that the corresponding position point of the i-th temperature flow detection unit is abnormal, that is, one side has a fault or aging;

[0067] If the second difference c2 of multiple consecutive detection points is greater than the second temperature difference threshold β, the middle detection point can be taken as the detection source and inspections can be performed in both directions, or the entire section can be inspected.

[0068] In this embodiment, the air duct monitoring module further includes N detection robots, which are distributed in the connecting pipes (the pipes may be square) between the first air duct 1 and the second air duct 2 .

[0069] The detection robot moves in the first air duct 1 or the second air duct 2, and takes pictures or senses the situation in the air duct to determine the problem location in the air duct. For example, when the temperature and flow detection parts compare and find that there is an abnormality at a certain position in the air duct, the detection robot moves to the abnormal position, takes pictures in a dark environment to confirm whether there are light leaks, and / or turns on the light source and then takes pictures of the working conditions of the air duct or the end equipment; the detection robot can also be equipped with other non-destructive testing devices.

[0070] In this embodiment, the detection robot is at the lower side of the air duct and moves along the air duct. It can be set as a structure such as a trolley with a camera. The detection robot can also be set as a sweeping robot with a camera, that is, the detection robot includes a sweeping machine component at the bottom, which can realize shooting and detection while facilitating the cleaning of dust accumulated in the air duct.

[0071] In this embodiment, a storage space is extended at a certain bending angle of the air duct, and the outer end of the storage space can be disassembled through an opening and closing door for the detection robot to store and replace items on a daily basis. A special moving path can also be set for the robot to move along the moving path, and the moving path is connected to the air duct only through a connecting channel, so that the robot's camera device can extend from the connecting channel into the air duct for shooting and detection.

[0072] like Figure 5 As shown, the present invention also provides a working method of a subway integrated air conditioning system, which specifically includes the following steps:

[0073] S1: The environmental parameters of the subway station are detected in real time through the environmental crowd monitoring module, and the target temperature is determined according to the environmental parameters.

[0074] In this embodiment, the environmental parameters include the temperature outside the subway station, the real-time weather, and the flow or number of people in the station.

[0075] S1-1: Obtain a temperature control table of the outside temperature-target temperature according to historical data statistics of the subway air conditioning system, and then obtain a first target temperature according to the real-time outside temperature and the temperature control table; the first target temperature can also be obtained by curve fitting;

[0076] S1-2: Divide the interior of the subway station into several areas according to the flow of people, and set the offset temperature of the corresponding area according to the level of the flow of people.

[0077] For example, the offset temperatures of different pedestrian flow intervals compared to the reference interval can be directly preset, the offset temperature of area A1 is a1, and the offset temperature of area A2 is a2; it can also be set to different levels in sequence, for example, for each level increase in pedestrian flow, the offset temperature is -0.5°C, so that the offset temperature = -0.5*the level difference with the reference interval.

[0078] S1-3: used to calculate the second target temperature corresponding to each area according to the offset temperature, where the second target temperature = the first target temperature + the offset temperature.

[0079] S2: Adjust the temperature inside the subway station to the target temperature through the air conditioning module.

[0080] The concentration of carbon dioxide inside the subway station is detected in real time. If the concentration of carbon dioxide is less than the first concentration threshold, there is no need to start the second air duct, and only the first air duct needs to be opened to supply air, so that the temperature inside the subway station reaches the target temperature; if the concentration of carbon dioxide is greater than or equal to the first concentration threshold and less than or equal to the second concentration threshold, the second air duct is opened to inhale waste air, and the waste air is sent into the first air duct to mix with fresh air, so that the temperature inside the subway station reaches the target temperature; if the concentration of carbon dioxide is greater than or equal to the second concentration threshold, the second air duct is opened to inhale waste air and discharge it directly, that is, the waste air is not sent into the first air duct to mix with fresh air, so that the temperature inside the subway station reaches the target temperature.

[0081] For example, it switches according to the concentration threshold of carbon dioxide or particulate matter, and directly discharges after exceeding the threshold. The threshold can be set by yourself. When the carbon dioxide concentration is less than 1000ppm, it is comfortable and no exhaust is required, that is, the first valve 24 and the second valve 25 are both closed; when the carbon dioxide concentration is in the range of 1000ppm-1500ppm, the first valve 24 is closed and the second valve 25 is opened, and the waste air can enter the first chamber 12 from the second chamber 22 through the second valve 25 and mix with the fresh air; when the carbon dioxide concentration is greater than 1500ppm, it is determined that the air is relatively turbid under the threshold state, and it is automatically switched to direct exhaust of waste air, that is, the second valve 25 is closed and the first valve 24 is opened.

[0082] S3: The air duct monitoring module detects the air duct information of the air conditioning module, and issues an alarm if any abnormality is found.

[0083] In this embodiment, the method for screening abnormal position points is:

[0084] A1: M temperature flow detection units are installed in the first air duct 1. Taking temperature as an example, calculate the first difference between the temperature of the first temperature flow detection unit and the temperature of the mth temperature flow detection unit c1 = T1-T m , T1 represents the temperature of the first temperature flow detection unit, T m represents the temperature of the mth temperature flow detection unit;

[0085] If the first difference c1 is less than the first temperature difference threshold α, it means that the temperature difference at both ends of the air duct is within the set range, which is a normal phenomenon; if the first difference c1 is greater than or equal to the first temperature difference threshold α, it means that the air duct or the connection at both ends of the air duct has aging or failure problems.

[0086] A2: Then calculate the temperature T of the i-th temperature flow detection unit i The second difference between the average temperature of two adjacent temperature flow detection units, T irepresents the temperature of the ith temperature flow detection unit, T i-1 represents the temperature of the i-1th temperature flow detection unit, T i+1 represents the temperature of the i+1th temperature flow detection unit;

[0087] If the second difference c2 is less than the second temperature difference threshold β, it means that the temperature difference between the corresponding position point of the i-th temperature flow detection unit and the two ends is relatively uniform, which is a normal phenomenon; if the second difference c2 is greater than or equal to the second temperature difference threshold β, it means that the corresponding position point of the i-th temperature flow detection unit is abnormal, that is, one side has a fault or aging;

[0088] If the second difference c2 of multiple consecutive detection points is greater than the second temperature difference threshold β, the middle detection point can be taken as the detection source and inspections can be performed in both directions, or the entire section can be inspected.

[0089] In this embodiment, when an abnormality is found, the detection robot is controlled to move in the first air duct 1 or the second air duct 2, and photograph or sense the situation in the air duct to determine the situation corresponding to the problem position in the air duct. For example, when the temperature and flow detection components compare and find that there is an abnormality at a certain position in the air duct, the detection robot moves to the abnormal position, photographs in a dark environment to confirm whether there are light leaks, and / or turns on the light source and then photographs the working conditions of the air duct or the end equipment; the detection robot can also be equipped with other non-destructive testing devices.

[0090] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
