Description

Technical Field

[0001] The present invention relates to the technical field of transmission and distribution pipelines of new energy buses, and in particular to a drying and waterproofing method, system and application of intelligent gas pipelines of new energy buses. Background Art

[0002] The air compressor of new energy buses is a device used to compress air and store it in the on-board high-pressure gas cylinder to provide a high-pressure gas source for the vehicle's braking system and other units. New energy buses generally adopt the air brake principle. The pneumatic brake system is widely used in the braking process of buses, using high-pressure air compressed by the air compressor for braking. During the operation of the air compressor, the compressed high-temperature and high-pressure air must ensure that the water content is lower than the design standard to avoid the impact of compressed air with a high water content on the air pipeline and pneumatic components during the transportation process, thereby ensuring the safety of pneumatic brakes of new energy buses.

[0003] When driving new energy buses in coastal areas, the proportion of moisture in the air is relatively high. The air compressor is prone to continuously accumulate moisture in the air storage tank during operation. The continuous accumulation of high-pressure air with high moisture content and supply to the brake system is prone to water accumulation, which is easy to freeze in low temperatures in winter, causing blockage of the brake valve and air path, resulting in bus brake failure and seriously affecting vehicle driving safety. In the prior art, the air compressor lacks corresponding dehumidification and waterproofing measures at both the air inlet and outlet ends to reduce the moisture content in the compressed air, and cannot ensure that the air compressor can form a stable output air pressure to achieve the expected effect. Summary of the invention

[0052] Example 1

[0053] See also Figure 1 and 2 As shown, the present invention is a drying and waterproofing method for an intelligent air pipeline of a new energy bus, comprising the following steps:

[0054] S10, obtaining the current intake air humidity value at the inlet end of the vehicle-mounted air compressor 1.

[0055] The method for obtaining the current intake air humidity value in this step includes: an intake gate valve 11 and an intake gate valve 2 12 are sequentially arranged on the air delivery direction of the intake pipe 10 of the vehicle-mounted air compressor 1, wherein the intake gate valve 11 is in a normally open state, and the intake gate valve 2 12 is in a normally closed state, and the intake gate valve 11 and the intake gate valve 2 12 are electrically connected to the ECU 3 respectively; an intake air humidity sensor 4 is arranged on the pipe section between the intake gate valve 11 and the intake gate valve 2 12, and the intake air humidity sensor 4 is used to obtain the current intake air humidity value and feed it back to the ECU 3.

[0056] S11. If the current intake air humidity value is greater than a preset intake air humidity threshold, an isolation dehumidification zone is formed in the intake pipe 10 of the air compressor 1, and the isolation dehumidification zone is preheated and dehumidified by the electronically controlled preheater 2.

[0057] In this step, the method for preheating and dehumidifying the isolated dehumidification zone includes: the intake humidity sensor 4 obtains that the current intake humidity value is greater than the preset intake humidity threshold, and the ECU3 electrically controls the intake gate valve 11 to close. At this time, the pipe section between the intake gate valve 11 and the intake gate valve 2 12 is a closed cavity, so that an isolated dehumidification zone is formed in the intake pipe 10 of the air compressor 1; the electronically controlled preheater 2 is turned on by the ECU3, and the isolated dehumidification zone is preheated and dehumidified by the electronically controlled preheater 2.

[0058] S12, inputting the dry air after preheating and dehumidification in the isolated dehumidification area into the air storage tank of the air compressor 1.

[0059] In this step, the method of inputting dry air into the air storage tank includes: first, if the intake humidity sensor 4 obtains a current intake humidity value that is less than the preset intake humidity threshold, the ECU3 electronically opens the intake gate valve 2 12. At this time, the intake gate valve 11 is in a normally open state, and dry air below the preset intake humidity threshold is input into the air storage tank; second, the humid air in the isolation dehumidification area is preheated and dehumidified until the intake humidity sensor 4 obtains a current intake humidity value that is greater than the preset intake humidity threshold, and the ECU3 electronically opens the intake gate valve 2 12. At this time, the intake gate valve 11 is in an electronically closed state, and dry air below the preset intake humidity threshold is input into the air storage tank.

[0060] During the use of the waterproof method of the present application, the inhaled air of the air intake pipe 10 of the air compressor 1 is detected in real time to determine whether the humidity of the inhaled air is within the preset air intake humidity threshold. If it is greater than the preset air intake humidity threshold, an isolation dehumidification zone is formed in the air intake pipe 10 of the air compressor 1, and the isolation dehumidification zone is preheated and dehumidified by the electronically controlled preheater 2. The isolation dehumidification zone is easy to operate to control the dry inhaled air, and can ensure that the humidity of the inhaled air is accurately controlled, so that the air compressor 1 can compress the dry air for gas storage, meet the needs of new energy buses running in coastal areas, ensure that the inhaled air is dry from the air intake end of the air compressor 1, and ensure that the air compressor 1 can form a stable output air pressure to achieve the expected effect.

[0061] During the use of the waterproof method of the present application, when the humid air in the isolation dehumidification zone is preheated and dehumidified, a temperature sensor 6 is provided on the pipe section between the air intake gate valve 11 and the air intake gate valve 2 12. The temperature sensor 6 is used to obtain the intake temperature value of the isolation dehumidification zone and feed it back to the ECU 3. When the air compressor 1 is in normal air intake, the intake temperature value of the isolation dehumidification zone obtained by the temperature sensor 6 will not exceed the preset intake temperature threshold. When the preheating and dehumidification operation is performed in the isolation dehumidification zone, the intake temperature value of the isolation dehumidification zone obtained by the temperature sensor 6 may exceed the preset intake temperature threshold. Generally, the preset intake temperature threshold is 40°C. In this way, the internal structural components of the air compressor 1 will not be damaged due to excessive temperature. Therefore, it is necessary to detect the intake temperature through the temperature sensor 6 and control the intake compression and storage below the preset intake temperature threshold.

[0062] During the use of the waterproof method of the present application, water will be generated during the preheating and dehumidification process of the isolation dehumidification zone. By connecting the drain pipe 13 to the air intake pipe 10, the drain gate valve 14 can be electronically opened through the ECU3 to facilitate the discharge of the water in the isolation dehumidification zone from the drain pipe 13, thereby preventing the accumulated water from affecting the preheating and dehumidification effect of the isolation dehumidification zone.

[0063] Example 2

[0064] Combination Figure 3As shown, the present invention also provides a waterproof system for an intelligent air pipeline of a new energy bus, including an intake humidity detection module 400, an outlet humidity detection module 500, an electric control preheating module 200, an air compressor execution end module 100 and an ECU control end module 300. The intake humidity detection module 400 is used for the current intake humidity value at the inlet end of the air compressor execution end module 100, and is fed back to the ECU control end module 300. The outlet humidity detection module 500 is used for the current outlet humidity value at the outlet end of the air compressor execution end module 100, and is fed back to the ECU control end module 300. The U control end module 300 and the electric control preheating module 200 are used to preheat and dehumidify the isolated dehumidification area. The air compressor execution end module 100 is used for the air compressor 1 to perform air intake, air compression, air storage and air discharge actions. The ECU control end module 300 is used to run the instruction generation program of the air intake humidity detection module 400, the air outlet humidity detection module 500, the electric control preheating module 200 and the air compressor execution end module 100. When the instruction generation program is executed by the ECU control end module 300, the drying and waterproofing method steps of the intelligent air pipeline of the new energy bus as mentioned above are implemented.

[0065] The waterproof system of the present application is convenient for intelligent control, and the detection data is fed back to the ECU control end module 300, so that analysis and judgment can be performed to control the electronically controlled preheating module 200 and the air compressor execution end module 100 to perform corresponding actions, which can ensure that the humidity of the inhaled air and the humidity of the output air are respectively precisely controlled, so that the air compressor 1 can compress dry air for storage or discharge, meeting the needs of new energy buses running in coastal areas. The air can be kept dry from the air inlet and outlet ends of the air compressor 1, thereby ensuring that the air compressor 1 can form a stable output air pressure to achieve the expected effect.

[0066] Example 3

[0067] Combination Figure 4 and Figure 5 As shown, the present invention also provides a waterproof application of an intelligent air pipeline for new energy buses, including an ECU3, wherein the ECU3 is used to run an application scenario program of an intake humidity sensor 4, an outlet humidity sensor 5, a temperature sensor 6, an electronically controlled preheater 2 and an air compressor 1. When the application scenario program is executed by the ECU3, the steps of the drying and waterproofing method for the intelligent air pipeline of the new energy bus are implemented as described above.

[0068] During the waterproof application process of the present application, the humidity of the inhaled air can be precisely controlled so that the air compressor 1 can compress the dry air for air storage, meeting the needs of new energy buses traveling in coastal areas. The inhaled air is ensured to be dry from the air inlet end of the air compressor 1, ensuring that the air compressor 1 can form a stable output air pressure to achieve the expected effect.

[0069] The steps of the waterproof method for the outlet of the vehicle-mounted air compressor 1 are as follows:

[0070] S20, obtaining the current outlet air humidity value of the air storage tank outlet of the air compressor 1.

[0071] The method for obtaining the current intake air humidity value in this step includes: an outlet gate valve 16 and an outlet gate valve 2 17 are sequentially arranged on the air delivery direction of the outlet pipe 15 of the vehicle-mounted air compressor 1, wherein the outlet gate valve 16 is in a normally closed state, and the outlet gate valve 2 17 is in a normally closed state, and the outlet gate valve 16 and the outlet gate valve 2 17 are electrically connected to the ECU3 respectively; an outlet air humidity sensor 5 is arranged on the pipe section between the outlet gate valve 16 and the outlet gate valve 2 17, and the ECU3 electronically controls the outlet gate valve 16 to open, and the outlet air humidity sensor 5 is used to obtain the current outlet air humidity value and feed it back to the ECU3.

[0072] S21. If the current outlet humidity value is greater than the preset outlet humidity threshold, a reflux temporary storage area is formed in the outlet pipe 15 of the air compressor 1, and the output air in the reflux temporary storage area is discharged to the inlet pipe 10 of the air compressor 1 through the return pipe 18, and preheated and dehumidified.

[0073] In this step, the method for discharging the output air in the reflux temporary storage area into the air inlet pipe 10 of the air compressor 1 includes: the outlet humidity sensor 5 obtains that the current outlet humidity value is greater than the preset outlet humidity threshold, and the ECU3 electrically controls the outlet gate valve 16 to open and the outlet gate valve 16 to close, so that a reflux temporary storage area is formed in the outlet pipe 15 of the air compressor 1; the reflux gate valve 19 is opened by the ECU3, and the output air in the reflux temporary storage area is discharged into the air inlet pipe 10 of the air compressor 1 through the return pipe 18, and preheating and dehumidification are performed.

[0074] S22, inputting the output air in the reflux temporary storage area into the pneumatic brake system or the air conditioning refrigeration system.

[0075] In this step, the method for applying the output air in the reflux temporary storage area includes: first, if the outlet air humidity sensor 5 obtains a current outlet air humidity value that is less than the preset outlet air humidity threshold, the ECU 3 electronically controls the outlet air gate valve 2 17 to open. At this time, the outlet air gate valve 16 is in a normally open state, and the dry air below the preset outlet air humidity threshold is output for application; second, the humid output air below the preset outlet air humidity threshold in the reflux temporary storage area is refluxed, and the electronically controlled preheater 2 is opened in the intake pipe 10 for preheating and dehumidification, until the condition that the outlet air humidity sensor 5 obtains a current outlet air humidity value that is less than the preset outlet air humidity threshold is met, and the dry air below the preset outlet air humidity threshold is output for application.

[0076] During the waterproof application process of the present application, the exhaust air of the air outlet pipe 15 of the air compressor 1 can be detected in real time to determine whether the exhaust air humidity is within the preset exhaust air humidity threshold. If it is greater than the preset exhaust air humidity threshold, a reflux temporary storage area is formed in the air outlet pipe 15 of the air compressor 1 to return the exhaust air to the air inlet pipe 10, and the reflux circulating air is preheated and dehumidified by the electronically controlled preheater 2, which can ensure that the humidity of the exhaust air is precisely controlled, so that the air compressor 1 can discharge dry compressed air to meet the needs of new energy buses running in coastal areas, and the exhaust air can be ensured to be dry from the air outlet end of the air compressor 1, ensuring that the air compressor 1 can form a stable output air pressure to achieve the expected effect.

[0077] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
