Referring to fig. 1 and 4, the return air inlet 12 of the blower unit is disposed above the blower unit, and the supply air outlet 11 is disposed below the blower unit. The pipe casing 2 has been seted up on the stratum, and air supply unit 1 of return air, air supply mode down is gone up to the embedding in pipe casing 2, in order to guarantee the air supply effect, all inlays whole supply-air outlet 11 in the pipe casing 2 to make the air that the supply-air outlet sent out get into in the pipe casing 2. In order to make the wind of tube seat get into the waiting room of railway station indoor, set up air-out grid 21 above the tube seat, air-out grid 21's the mode of setting is: the grid density is reduced in an interval mode according to the distance from the air supply outlet of the air supply unit to the air supply outlet from small to large and according to the preset interval, and the air output above the pipe groove is the same when the air is supplied to the maximum. The air-out grid sets up the principle and does: the air outlet grille at the position close to the air supply outlet has high density, the air outlet grille at the position far away from the air supply outlet has low density, the higher the density is, the higher the resistance is, and the wind can flow to the position with low resistance; meanwhile, the dynamic pressure of air supplied at the position close to the air supply outlet is large, and the dynamic pressure at the far position is small; the two parameters are combined, the density of the grating is adjusted, and the same air output at each position is ensured when the maximum air supply is carried out.
For example, referring to fig. 2, in the embodiment of the present invention, the density of the outlet grilles may be set to 3, the density of the outlet grilles near the air outlet is the highest, and the upper portion of the duct is divided into 3 sections according to the different densities of the outlet grilles, and the section a, the section B, and the section C are marked (where the density of the outlet grilles in the section a is the highest). A plurality of seats are provided for each section, and in the present embodiment, description will be given by taking an example in which 15 seats are provided for each section. In this embodiment, the temperature detectors are respectively disposed at the farthest positions from the air supply outlets of the corresponding sections, and the temperature detector is disposed at the rearmost end of each section region, such as the tail end of the a1 region, so that the whole a1 region can only satisfy the set temperature if it is ensured that the tail end temperature of the a1 region satisfies the set temperature.
In some embodiments, optionally, for example, the configuration is convenient, the number of the duct slots is several, for example, 1, 2, 3, and the like, and the air supply outlet is connected to one end of the duct slot through the splitter 13; the diverter 13 is connected with the control module and divides the air of the air supply outlet into a plurality of pipe grooves.

For example, each blower unit can blow the duct channel flow path including one split flow, two split flows, three split flows, etc., and more flow paths can be provided, and the specific number of flow paths can be set according to the size of the air conditioning unit or occasion needs, etc. The seats are uniformly arranged above the air supply grilles, and meanwhile, the region division is carried out according to different grille densities, such as a1 region, a B1 region, a C1 region and the like in fig. 2. For example, fig. 3 is a schematic diagram of a flow divider according to different flow divisions according to an embodiment of the present invention; fig. 3(a) is a schematic cross-sectional view, fig. 3(b) is a schematic cross-sectional view, and fig. 3(c) is a schematic cross-sectional view. Referring to fig. 3, when the number of the duct slots is more than 1, a splitter may be provided at the air blowing port, and the splitting flow path may be set according to the number of the duct slots. In order to realize the control of the air flow, an adjusting air valve can be arranged behind the flow divider and in front of the pipe groove, for example, an automatic adjusting air valve is adopted in the embodiment.

Fig. 5 is a schematic view of a working principle of a pipe-groove type air supply system according to an embodiment of the present invention, referring to fig. 5, a control module may be respectively connected to a pressure detector, a temperature detector, an air regulating valve, a blower M1 of an air supply unit, and a display module through a wireless or communication line D, and the control module respectively collects detection information of a connection piece and sends a control instruction to the connection piece. Wherein, the display component can be a display screen. In this embodiment, the control module is configured at the blower set. Wherein, the display module can be the display screen of going out fan group, also can be the display screen of waiting room.
In order to explain the air supply control method in the present invention, in this embodiment, a two-split flow is taken as an example to explain the technical solution, and the section is divided into an a1 area, a B1 area, a C1 area, an a2 area, a B2 area, and a C2 area under the two-split flow, where the a1 area is opposite to the a2 area, the B1 area is opposite to the B2 area, and the C1 area is opposite to the C2 area. A first adjusting air valve 141 is arranged at the joint of the A1 area and the air supply outlet, and a second adjusting air valve 142 is arranged at the joint of the A2 area and the air supply outlet.
After the control module acquires the pressure detection information, whether a person is on the seat in the corresponding section is judged according to the pressure detection information. When the fact that a person sits on the seat is judged, the fact that a passenger has a rest in the zone is indicated, at the moment, whether the temperature detection information of the zone is within a temperature threshold value is judged, for example, the temperature threshold value can be 18-24 ℃ in summer and 16-22 ℃ in winter, and when the fact that the current temperature value is not within the set temperature threshold value is judged, a fan of a corresponding fan unit (such as an air conditioner) is triggered to be started to carry out cooling or heating until the temperature value of the zone is maintained within the temperature threshold value. When the flow divider and the adjusting air valve are arranged, the corresponding adjusting air valve is triggered to be opened to the maximum opening degree.
In the following examples, refrigeration is taken as an example to explain the scheme simply.
In some embodiments, the air supply is controlled by using the duct-and-slot type air supply system provided by the application. And the control module is used for judging whether the temperature detection information of the interval is within the temperature threshold value when personnel exist in the interval, and if not, triggering to start the corresponding fan unit and the corresponding adjusting air valve so as to enable the temperature information of the interval to be within the temperature threshold value.
For example, to conserve resources, the identification may be made at the waiting room identification component: please enter the seat in sequence, which is: a1 → A2 → B1 → B2 → C1 → C2. Wherein, for the convenience of passenger to look over, the sign subassembly can be for waiting room display screen, also can show at the display screen of air conditioner.
When no passenger sits in the corresponding interval area, the air blower unit is in a standby or shutdown state, and the display screen displays the state of the air blower unit, the current number of seats and the current temperature value of each interval area. When any passenger enters the waiting room, the passenger enters the waiting room according to the set seating sequence.
Table 1 is a display schematic table of a display when no person is seated according to an embodiment of the present invention.
TABLE 1
For example, after a passenger enters a waiting room, the passenger preferably enters a waiting room in a region a1, when a pressure detector under a seat in a region a1 senses pressure, the pressure information is sent to a control module, the control module receives the pressure information and then turns on a blower unit (such as an air conditioner), the rotation speed of a fan of the air conditioner is gradually increased from low to high, the first adjusting air valve 141 is opened to the maximum opening degree, and the second adjusting air valve 142 is closed. When the temperature detector in the area A1 detects that the temperature is K ℃ (K is the set refrigeration temperature of the air conditioner, the most comfortable temperature of the human body is 18-24 ℃ in summer, the most comfortable temperature of the human body is 16-22 ℃ in winter, and K is respectively positioned in data between two groups of numerical values or a certain range between the two groups of numerical values in summer and winter), the temperature detector feeds back the temperature information to the control module, and the control module controls the fan to keep the current running state.
In some embodiments, optionally, the control module is configured to: judging whether the pressure detection information belongs to the same interval or not; if the pressure detection information does not belong to the same interval, sequentially judging whether the seat in the previous interval is fully seated according to a preset seating sequence; if the seat in the previous section is full, the corresponding fan unit in the next section and the corresponding adjusting air valve are opened.
For example, when the pressure detection information is determined to be the numerical values of the two areas a1 and a2, it is determined whether the area a1 is fully seated, and if the area a1 is not fully seated, the area a2 is not opened, and passengers in the area a2 may be prompted, such as "please seat in order". Similarly, if the pressure detection information is areas a1, a2 and B1, the area B1 will be activated after the areas a1 and a2 are full of people. The control method of other areas is the same, and is not described herein.
When the seats in the A1 area are fully seated, the seats in the A1 area cannot meet the number of passengers, and the A1 and the A2 area need to be cooled simultaneously, the first adjusting air valve 141 and the second adjusting air valve 142 are opened to the maximum opening degree simultaneously, the fan continues to increase the rotating speed, and when the temperature detectors in the A1 and the A2 areas detect that the temperature meets K ℃, temperature information is fed back to the control module, and the control module controls the fan to keep the current running state.
When the areas A1, A2 and B1 need to be cooled simultaneously, the fan rotating speed, the first adjusting air valve 141 and the second adjusting air valve 142 are opened simultaneously for adjustment. When the temperature detectors at the positions A2 and B1 meet the set temperature K ℃, the temperature information is fed back to the control module, and the control module controls the rotating speed of the fan, the first adjusting air valve 141 and the second adjusting air valve 142 to keep the current states.
When other areas need to be refrigerated, the control method is the same as the simultaneous refrigeration control mode of the areas A1, A2 and B1, and details are not described here. At the moment, the display screen can display the starting state, the current number of vacant seats, the current temperature of each area and the like. Table 2 is a display screen display schematic table for simultaneously cooling in regions a1, a2, and B1 according to an embodiment of the present invention.
TABLE 2
In some embodiments, optionally, the control module is configured to: after the seats in any interval are judged to be full, in a first preset time interval, if the persons on the first preset number of seats in the interval leave, the state of the fan unit and the state of the corresponding adjusting air valve are maintained.
For example, in a waiting room of a train station, the waiting room is only a place where passengers temporarily wait while traveling, all waiting rooms are basically scattered passengers to get in, and when a vehicle arrives, a large number of passengers often leave at the same time to get on the train. Therefore, when a passenger or passengers leave the seats in a waiting room, the passengers can go to shopping or go to a toilet and then return, so that the passengers can take the seats conveniently and energy is saved. In this embodiment, after a person in a certain area is fully seated, in a first preset time interval, if there are a first preset number of persons (a small number of persons, for example, 15 persons are determined in each area, the first preset number may be 3 persons) to leave, the turning on of the air conditioner in the next area is not affected.
In some embodiments, optionally, after it is determined that the seats in any one section are fully seated, in a second preset time interval, if the persons on the seats in the second preset number in the section leave, the number of the persons who do not leave the seats is obtained, and the number of the sections in which the fan unit needs to be started and the air valves need to be adjusted correspondingly is calculated according to the number of the persons who do not leave the seats; the second preset number is larger than the first preset number.
For example, in a second time interval between people fully sitting, a second preset number (a large number of people, e.g., 15 people are checked per area, and the second preset number may be 8 people) of passengers leave the seat at the same time, and after the control module receives the leaving information, the control module controls the air conditioner to determine that several areas are needed to turn on the air conditioner according to the current remaining number of people, and displays the information on the display screen. For example, when 10 people remain in areas a1, a2 and B1, and it is determined that the passenger's riding requirements can be met by only opening area a1, the areas a2 and B1 are triggered to be closed, and the passenger is prompted to enter the area a 1. The prompting mode may be a voice prompt, a display screen prompt, or the like, and is not limited specifically here.
In some embodiments, optionally, the method further includes: a display; the display is connected with the control module; the display is used for displaying the preset seating sequence, the current temperature information of each interval or the on-off state of the air supply unit.
