The embodiment of the air supply method of the train air conditioning system comprises the following steps:
the air blowing method of the inter-train air conditioning system 100 of the present invention is a software program applied to the main controller 1 of the inter-train air conditioning air blowing system in the above-described embodiment, and is used to control the air blowing states of the first fan group 21 and the second fan group 22 of the inter-train air conditioning 2 of the inter-train air conditioning system 100.
As shown in fig. 4, the air supply method of the inter-train air conditioning system 100 of the present embodiment includes a presetting step, a sampling step, and an operating step, and specifically, when the air supply method of the inter-train air conditioning system 100 controls the first fan set 21, the step S10 is executed first, that is, the presetting step, the presetting unit 11 of the main controller 1 obtains a first operating instruction, and determines a first preset angle according to the first operating instruction; acquiring a third operating instruction, and determining a first set angle according to the third operating instruction, wherein the first preset angle is used for controlling the rotation angle of the first fan unit when the absolute value of the first temperature difference is greater than a first preset threshold; the first set angle is used for controlling the rotation angle of the first fan unit when the absolute value of the first temperature difference value is smaller than a first preset threshold value.

Similarly, the user can set the rotation mode of the first fan unit 21 in the normal operation state according to the actual installation position of the inter-row air conditioner 2, for example, the user can set the rotation mode of the first fan unit 21 of the inter-row air conditioner 2 in the normal operation state to the constant angle air supply, the constant angle rotation air supply, the automatic air sweeping, or the like according to the actual installation position of the inter-row air conditioner 2.

If the operation unit 13 determines that the first temperature difference is greater than the first preset threshold, step S40 is executed, the main controller 1 sends a first control instruction to the first fan unit 21, and after the first fan unit 21 obtains the first control instruction, the first fan unit turns to the side with the larger temperature value in the first temperature sensor 3 and the second temperature sensor 4 according to the first preset angle. Specifically, when the first temperature difference is greater than a first preset threshold, the operating unit 13 sends a first control instruction to the first fan unit 21, so that the first air deflector of the first fan unit 21 guides the cold air to the side with the higher temperature value of the space, and cools the area, so as to ensure that the server in the area can normally operate.

Specifically, when the first temperature difference is smaller than the first preset threshold, at this time, the operation unit 13 determines that refrigeration is not required for a certain specific area, so that the operation unit 13 controls the first fan unit 21 to rotate or automatically sweep air according to a first set angle, so that the temperature around the inter-row air conditioner 2 is maintained in a relatively stable state, and normal operation of the server is ensured.
The air blowing method of the inter-train air conditioning system 100 can control the second fan group 22 independently and simultaneously when controlling the first fan group 21. Specifically, as shown in fig. 5, step S11 is first executed, that is, the presetting step further includes: the preset unit 11 of the main controller 1 acquires a second operation instruction, and determines a second preset angle according to the second operation instruction; acquiring a fourth operation instruction, and determining a second set angle according to the fourth operation instruction, wherein the second preset angle is used for controlling the rotation angle of the second fan unit when the absolute value of the second temperature difference is greater than a second threshold; the second set angle is used for controlling the rotation angle of the second fan unit when the absolute value of the second temperature difference value is smaller than a second preset threshold value. The user can determine the rotation angle range of the second fan set 22 according to the relative positions of the third temperature sensor 5, the fourth temperature sensor 6 and the inter-row air conditioner 2, and can send a corresponding operation instruction to the preset unit through the touch screen display of the inter-row air conditioner 2 according to the determined angle range value, so that the rotation angle range of the second fan set 22 is set, and a second preset angle is determined. Similarly, the user can set the rotation mode of the second fan unit 22 in the normal operation state according to the actual installation position of the inter-row air conditioner 2, for example, the user can set the rotation mode of the second fan unit 22 in the inter-row air conditioner 2 in the normal operation state to the constant angle air supply, the constant angle rotation air supply, the automatic air sweeping, or the like according to the actual installation position of the inter-row air conditioner 2.
The sampling step further comprises: after the second preset angle and the second set angle are set, the inter-train air conditioning system 100 may operate according to the control program. At this time, the sampling unit 12 of the main controller 1 executes step S21, and acquires the third temperature value detected by the third temperature sensor 5 and the fourth temperature value detected by the fourth temperature sensor 6.
The executing step further comprises: after acquiring the third temperature value and the fourth temperature value, the sampling unit 12 sends the third temperature value and the fourth temperature value to the operation unit 13, so that the operation unit 13 compares the third temperature value and the fourth temperature value, that is, step S30 is executed, and whether a second temperature difference value between the third temperature value and the fourth temperature value is greater than a second preset threshold value is determined. If the operation unit 13 determines that the second temperature difference is greater than the second preset threshold, step S40 is executed, the main controller 1 sends a second control instruction to the second fan unit 22, and after the second fan unit 22 obtains the second control instruction, the second fan unit turns to the side with the larger temperature value in the third temperature sensor 5 and the fourth temperature sensor 6 according to the second preset angle. Specifically, when the second temperature difference is greater than the second preset threshold, the operating unit 13 sends a second control instruction to the second fan unit 22, so that the second air deflector of the second fan unit 22 guides the cold air to the side with the higher temperature value of the space, and cools the area, thereby ensuring that the server in the area can normally operate.
If the operating unit 13 determines that the second temperature difference is smaller than the second preset threshold, step S50 is executed, the main controller 1 outputs a fourth control instruction to the second fan unit 22, and the second fan unit 22 rotates or automatically sweeps air according to a second set angle after acquiring the fourth control instruction. Specifically, when the second temperature difference is smaller than the second preset threshold, at this time, the operation unit 13 determines that refrigeration is not required for a certain specific area, so that the operation unit 13 controls the second fan unit 22 to rotate or automatically sweep air according to the first set angle, so that the temperature around the inter-row air conditioner 2 is maintained in a relatively stable state, and normal operation of the server is ensured.
Further, as shown in fig. 6, the air supply system of the train air conditioning system 100 further includes a detection step, and first, step S12 is executed, the operation unit 13 of the main controller 1 determines whether or not the first abnormality information or the first failure information transmitted by the first temperature sensor 3 and/or the second temperature sensor 4 is acquired, and when the operation unit 13 of the main controller 1 determines that the first abnormality information or the first failure information is acquired, step S22 is executed, and the main controller 1 controls the first fan group 21 to rotate or automatically sweep air according to the first set angle. Specifically, after the operating unit 13 of the main controller 1 acquires the first abnormal information or the first failure information, the first fan unit 21 is controlled to rotate or automatically sweep air according to a first set angle. When the first temperature sensor 3 and/or the second temperature sensor 4 are abnormal or have a fault, the first temperature sensor 3 and/or the second temperature sensor 4 outputs abnormal information or fault information to the operating unit 13 of the main controller 1, so that the operating unit 13 can adjust the rotation mode of the first fan set 21 in time, for example, the rotation mode of the first fan set 21 is set to fixed-angle air supply, fixed-angle rotation air supply, automatic air sweeping, or the like, so as to ensure the normal operation of servers around the inter-row air conditioner 2.
As shown in fig. 7, first, step S13 is executed, the operation unit 13 of the main controller 1 determines whether or not to acquire the second abnormality information or the second failure information transmitted by the third temperature sensor 5 and/or the fourth temperature sensor 6, and when the operation unit 13 of the main controller 1 determines that the second abnormality information or the second failure information is acquired, step S23 is executed, and the main controller 1 controls the second fan group 22 to rotate or automatically sweep air according to the second set angle. Specifically, after the operating unit 13 of the main controller 1 acquires the second abnormal information or the second failure information, the first fan unit 21 is controlled to rotate or automatically sweep air according to a second set angle. When the third temperature sensor 5 and/or the fourth temperature sensor 6 are abnormal or have a fault, the third temperature sensor 5 and/or the fourth temperature sensor 6 outputs abnormal information or fault information to the operating unit 13 of the main controller 1, so that the operating unit 13 can adjust the rotation mode of the second fan set 22 in time, for example, the rotation mode of the second fan set 22 is set to fixed-angle air supply, fixed-angle rotation air supply, automatic air sweeping, or the like, so as to ensure the normal operation of servers around the inter-row air conditioner 2.
