Description

Technical Field

[0001] This utility model relates to the field of EMU commissioning technology, and in particular to an electro-pneumatic triggering device for pressure wave protection testing of the air conditioning system of the Fuxing EMU. Background Technology

[0002] The Fuxing bullet train is a high-speed train independently developed by China with complete intellectual property rights. It integrates a large number of domestically produced high technologies, with significant breakthroughs in key technologies such as traction and braking. Chinese standards account for over 80% of the many important standards involved. The Fuxing electric multiple unit mainly consists of the car body structure and traction system, with power traction methods including centralized and distributed power. It covers different speed levels such as 160, 250, and 350 km / h, adapting to diverse environments such as high altitudes, extreme cold, and sandstorms. It boasts advantages such as long service life, high comfort, and low running resistance.

[0003] During the commissioning phase of the Fuxing bullet train, pressure wave protection tests of the air conditioning system are required. Current methods require two testers to simultaneously and rapidly strike the pressure wave sensor's air pressure detection port with their hands, causing a change in external pressure and creating a pressure difference with the internal pressure, thus triggering the pressure wave protection function. This method poses a risk of injury to the testers' hands, and the two testers need to maintain a certain level of synchronization during the striking process. If the striking frequency is inconsistent, the operation must be repeated until the pressure wave protection function is triggered, resulting in significant labor intensity. Furthermore, the high position of the pressure wave sensor's detection port, limited by manufacturing facilities such as bullet train production plants or depots, makes it difficult to trigger pressure waves, further complicating the testing process.

[0015] In the above technical solution, the electronic control module is also equipped with a time-delay power-off relay designed based on the pressure wave logic principle.

[0016] In the above technical solution, the time-delayed power-off relay is equipped with a 3-second delay before disconnection.

[0046] Example 1

[0047] like Figure 1-3 As shown:

[0048] The present invention relates to an electro-pneumatic triggering device for pressure wave protection testing of the air conditioning system of a Fuxing high-speed train, comprising: an electro-pneumatic triggering device 10 and a Fuxing high-speed train test vehicle 20;

[0049] in,

[0050] The electro-pneumatic triggering device 10 includes an electronic control module 40 and an air circuit control module 30.

[0051] The test vehicle 20 of the Fuxing bullet train is equipped with a first pressure wave sensor detection port adapter 36 and a second pressure wave sensor detection port adapter 37.

[0052] The electro-pneumatic triggering device 10 is connected to the first pressure wave sensor detection port adapter 36 and the second pressure wave sensor detection port adapter 37 in the Fuxing EMU test vehicle 20 through the second air connection hose 33 and the third air connection hose 34. It is then connected to the left side 21 and the right side 22 of the pressure wave sensor detection port, respectively, to synchronously generate air pressure, thereby creating a pressure difference between the inside and outside of the Fuxing EMU test vehicle 20, thus triggering the pressure wave protection function of the EMU air conditioning system and completing the test.

[0053] like Figure 2 As shown:

[0054] In the pressure wave protection test electro-pneumatic triggering device of the air conditioning system of the Fuxing high-speed train of this utility model, the electro-pneumatic triggering device 10 mainly includes: air circuit control module 30 and electro-control module 40.

[0055] The present invention relates to an electronically controlled pneumatic triggering device for pressure wave protection testing of the air conditioning system of the Fuxing high-speed train. The pneumatic control module 30 and the electronic control module 40 are connected by a connecting cable 41. The electronic control module 40 transmits electronic control commands to the pneumatic control module 30 through the connecting cable 41.

[0056] like Figure 3 As shown:

[0057] The air circuit control module 30 is a functional module that generates a pressure difference between the inside and outside of the Fuxing high-speed train test vehicle 20. The air circuit control module 30 includes a pneumatic pump 31 and a composite air valve 35. The electrical control module 40 transmits electrical control commands to the air circuit control module 30 via a connecting cable 41 to control the start or stop of the pneumatic pump 31. After the pneumatic pump 31 starts, the generated pressurized air reaches the composite air valve 35 through the first air connection hose 32. After the composite air valve 35 evenly distributes the air pressure, the air pressure sequentially passes through the second air connection hose 33 and the first pressure wave sensor detection port adapter 36 (wherein, the second air connection hose 33 and the first pressure wave sensor detection port adapter 36 are sealed). The air valve 35, with a sealed connection, connects to the left side 21 of the pressure wave sensor detection port, thereby increasing the pressure at the left side 21 of the pressure wave sensor detection port and generating a trigger signal for pressure wave protection. Conversely, air pressure sequentially passes through the third air connection hose 34 and the second pressure wave sensor detection port adapter 37 (wherein, the third air connection hose 34 and the second pressure wave sensor detection port adapter 37 are a sealed connection) and connects to the right side 22 of the pressure wave sensor detection port, thereby increasing the pressure at the right side 22 of the pressure wave sensor detection port and generating a trigger signal for pressure wave protection. After the composite air valve 35 evenly distributes the air pressure, the air pressure is evenly and simultaneously delivered to the second air connection hose 33 and the third air connection hose 34 for operation. The exhaust valve 38 can exhaust compressed air from all air lines in the air circuit control module 30.

[0058] like Figure 2 As shown:

[0059] The electronic control module 40 is a circuit control module designed based on the triggering conditions of the pressure wave protection function logic of the air conditioning system of the Fuxing EMU. It controls the pneumatic pump 31 in the air circuit control module 30 through the connecting cable 41.

[0060] The electronic control module 40 includes: an external power plug 42 (for connecting to an external AC220V power supply), a main circuit air circuit breaker, a control circuit air circuit breaker, an emergency stop button, a self-reset button, a time-delay power-off relay (designed based on the pressure wave logic principle with a 3-second delay before disconnection), and a pneumatic pump closing contactor (two normally open contacts are provided to improve the circuit's segmentation capability, thereby ensuring the pneumatic pump can be reliably disconnected). The pneumatic pump 31 provides air pressure to the air circuit control module 30, thereby generating a pressure difference between the inside and outside of the Fuxing EMU test vehicle 20 and triggering the air conditioning system pressure wave protection function.

[0061] In the pressure wave protection test electro-pneumatic triggering device for the air conditioning system of the Fuxing high-speed train of this utility model, the components of the electrical control module 40 are composed of any general electrical components, all of which are modules known in the art.

[0062] The functions of electronic control modules known in the art include: motor control, energy management, dynamic response, and safety; among which:

[0063] Motor control:

[0064] The electronic control module converts direct current (DC) to alternating current (AC) through an inverter to drive the motor and convert electrical energy into mechanical energy.

[0065] Energy Management:

[0066] The electronic control module is responsible for monitoring the battery status, managing the battery charging and discharging process, ensuring that the battery operates within a safe range, thereby extending battery life.

[0067] Dynamic response:

[0068] The electronic control module needs to have high dynamic response capability to adapt to the needs of the vehicle under different operating conditions, such as acceleration, deceleration and hill climbing.

[0069] Safety: The electronic control module must also have high safety to prevent overload, short circuit and other faults, and ensure the safe operation of the vehicle.

[0070] The components of a conventional electronic control module, as known in the art, include: an IGBT module, a controller, and a sensor; wherein:

[0071] IGBT module: Responsible for controlling the direction and frequency of current flow, it is a key part of the electronic control module.

[0072] Controller: Based on power semiconductor hardware and software design, it controls the motor's operating status in real time and provides other control functions.

[0073] Sensors: Used to monitor motor status and provide real-time data to the controller for decision-making.

[0074] The usage process of the electro-pneumatic triggering device for pressure wave protection test of the air conditioning system of the Fuxing bullet train of this utility model includes:

[0075] First, connect the external power plug 42 of the electrical control module 40 to AC220V; the main circuit air circuit breaker is closed, the control circuit air circuit breaker is closed, and the emergency stop button is not pressed and is in the ON position. Press the control circuit start button to energize the time-delay power-off relay, which closes the auxiliary normally open contact of the time-delay power-off relay, energizing the pneumatic pump closing contactor. After the pneumatic pump closing contactor is energized, its two pairs of normally open contacts close, energizing the pneumatic pump 31.

[0076] Second, after the electronic control module 40 starts the pneumatic pump 31 in the pneumatic circuit control module 30 through the connecting cable 41, the generated air pressure reaches the composite air valve 35 through the first air connection hose 32. After the composite air valve 35 evenly distributes the air pressure, the air pressure is respectively increased through the second air connection hose 33 and the first pressure wave sensor detection port adapter 36 and through the third air connection hose 34 and the second pressure wave sensor detection port adapter 37, respectively, to the left side 21 and the right side 22 of the pressure wave sensor detection port, generating a trigger signal for pressure wave protection and completing the pressure wave protection function test.

[0077] Third, after pressing the self-reset button and briefly starting the circuit, the delayed power-off relay is immediately de-energized. The auxiliary normally open contact of the delayed power-off relay automatically opens after 3 seconds, de-energizing the pneumatic pump's closing contactor and stopping the pneumatic pump 31. Operate the exhaust valve 38 in the air circuit control module 30 to purge compressed air from all air lines in the module. After purging, disconnect the exhaust valve 38. This completes one test of the air conditioning system pressure wave protection trigger function.

[0078] This utility model relates to an electro-pneumatic triggering device for testing the pressure wave protection of the air conditioning system of the Fuxing bullet train. The test vehicle can be tested independently by one tester using this device. This eliminates the drawback of the original test method, which required two testers to operate the pressure wave sensor wind pressure detection port at the same time, and changes the operation of the pressure difference between the inside and outside of the vehicle, so as to achieve the effect of reducing personnel and increasing efficiency.

[0079] The present invention relates to an electro-pneumatic triggering device for pressure wave protection testing of the air conditioning system of the Fuxing bullet train. This device eliminates the need for manual tapping of the pressure wave sensor's air pressure detection port during the pressure wave protection test of the air conditioning system of the Fuxing bullet train during the train commissioning phase. This would change the external pressure of the train and create a pressure difference with the internal pressure, thereby triggering the pressure wave protection function.

[0080] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
