Description

Technical Field

[0001] The invention relates to the technical field of motor vehicle groups, and more particularly to an intelligent debugging device, a debugging system and a debugging method for brake pressure of a motor vehicle group. Background Art

[0002] Many pressure sensors are used in the EMU braking system to convert pressure signals into electrical signals for common braking control, emergency braking control, parking brake control, air compressor start and stop control, etc. According to their functions, they can be divided into: total air pressure sensor, brake cylinder pressure sensor, brake air supply pressure sensor, parking brake cylinder pressure sensor, common brake pre-control pressure sensor, emergency brake pre-control pressure sensor and air spring pressure sensor, etc., which play a vital role in the braking control system.

[0003] During the advanced maintenance of EMUs, comprehensive functional verification of the brake system is required. By collecting the pressure data of each air cylinder under different braking conditions, the entire brake system is ensured to function normally. The traditional method is that the operator manually collects the pressure of the brake pressure system of each carriage one by one through the air pressure gauge, and compares it with the pressure data monitored by the train network system. On average, a short-length EMU needs to collect about 280 pressure data. This method has the problems of low detection accuracy, easy errors in manual recording, cumbersome operation and low efficiency. The existing technology has initially realized the unified external electronic collection device to collect the pressure of the brake pressure system of each carriage, but this method still requires personnel to be on duty in the driver's cab or to simulate personnel control through electronic equipment to perform multiple braking operations and brake relief operations, resulting in the main air compressor to frequently start and stop air supply, which cannot effectively save manpower and energy, and improper operation may bring safety hazards.

[0004] In addition, when the EMU is statically debugged in the maintenance depot, the rapid switching of brake pressure and the frequent starting and stopping of the main air compressor during simulated driving will cause unstable air pressure, thus affecting the accuracy and reliability of the debugging data.

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an intelligent debugging device, a debugging system and a debugging method for EMU brake pressure, which utilizes the intelligent debugging device to actively supply air pressure, and obtains the air path air pressure value by comparing the supplied air pressure data with the sensor pressure data read by the EMU brake control box (BCU).

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0020] Reference Figure 1-2A motor vehicle brake pressure intelligent debugging device includes a shell 1, and detection quick-action interfaces 8 are arranged on the outside of the shell 1. In this embodiment, the number of detection quick-action interfaces 8 is 6 and they are symmetrically arranged. An air circuit switching valve 15 is provided in the shell 1. The valve port of the air circuit switching valve 15 is correspondingly connected to the detection quick-action interface 8, so as to adjust the connectivity status of different detection quick-action interfaces 8 through the air circuit switching valve 15.

[0021] Specifically, in the present embodiment, the gas circuit switching valve 15 is a six-way ball valve. In other embodiments, the gas circuit switching valve 15 can also be set as a valve with other communication ports greater than six-way.

[0022] Furthermore, a control main board 9 is provided in the outer shell 1, and the control main board 9 is controlled and connected to the gas circuit switching valve 15 to control the connectivity of the gas circuit switching valve 15. A battery 11 is provided at the bottom of the control main board 9, and the battery 11 is used to power the control main board 9. In addition, a charging port 5 is provided on the outer side of the outer shell 1 corresponding to the battery 11 to complete the charging operation of the battery 11.

[0023] Furthermore, a storage unit is provided on the control mainboard 9 to store data received by the control mainboard 9. The storage unit includes a hard disk or any other storage device in the prior art, which is not specifically limited here.

[0024] In addition, the control main board 9 also includes a network main board 13 and a network communication component for realizing a communication connection. The network communication component is connected to the control main board 9 through the network main board 13. At the same time, the network communication components between different debugging devices can communicate with each other to form a network. In this embodiment, the network communication device is specifically a lora antenna 6 arranged on the outside of the outer shell 1, and the network main board 13 realizes a local area network communication connection through the lora antenna 6.

[0025] In other embodiments, the network communication component may also use communication connection methods such as WiFi, Bluetooth, etc.

[0026] Furthermore, a display component is also provided on the housing 1 , and the display component is used to display the output data of the control mainboard 9 , and the display component is preferably a display screen 4 .

[0027] Furthermore, the alarm component is an indicator light 2 arranged on the housing 1. The indicator light 2 can be set to emit light of different colors individually, or multiple indicator lights can be set to emit light of a single color. The use of the indicator light 2 can facilitate observation by operators at a distance.

[0028] In another embodiment, the alarm component is a sound-generating device, which emits a prompt sound to alert the operator.

[0029] In another embodiment, the alarm components include an indicator light 2 and a sound-generating device, and the two work together to improve the alarm effect.

[0030] Furthermore, the detection quick-action interface 8 includes an air source interface 801, which is used to connect the air source. A total air control valve is provided at the air source interface 801, and the total air control valve is connected to the control main board 9. The control main board 9 is used to regulate the opening and closing of the total air control valve. The air source supplies air to the direction of the air circuit switching valve 15 through the air source interface 801, and controls the opening and closing of the air circuit through the total air control valve.

[0031] Specifically, the gas source is preferably an air compressor on the train. In another embodiment, the gas source is also an external air supply.

[0032] Furthermore, a main sensor 10 is provided between the main control valve and the gas circuit switching valve 15. When the main control valve controls the gas circuit to be opened, the gas source supplies air to the gas circuit switching valve 15, and the main sensor 10 can detect the size of the gas supply pressure.

[0033] Furthermore, the detection quick-acting interface 8 also includes a pressure regulating port 802, which is connected to the train relay valve. The control main board 9 is connected to the pressure regulating port 802 by adjusting the air circuit switching valve 15, so that the air source can supply a pre-control pressure (Cv) to the relay valve. A pressure regulating sensor is provided at the pressure regulating port 802 to read and record the pressure supply data of the pressure regulating port 802, and a pressure regulating valve 12 is provided at the pressure regulating port 802. The pressure regulating valve 12 is used to adjust the air pressure supplied by the pressure regulating port 802. In this embodiment, the pressure regulating valve 12 is specifically an electronic pressure regulating valve 12, and is connected to the control main board 9 to facilitate the control main board 9 to adjust its pressure regulation size.

[0034] Furthermore, the detection quick-action interface 8 also includes a detection port 803, which is used to transfer the air cylinder where the on-board pressure sensor is located. In this embodiment, the number of on-board pressure sensors of a single train section detected is 3, which are respectively brake pressure (C), spare brake pre-control pressure sensor (STV), and air spring pressure sensor (T). The corresponding number of detection ports 803 is also 3 and they are connected in sequence to the air cylinders corresponding to the brake pressure (C), spare brake pre-control pressure sensor (STV), and air spring pressure sensor (T).

[0035] During the train brake pressure relief process, the control main board 9 closes the main air control valve, and at the same time adjusts the air circuit switching valve 15 to sequentially switch the air cylinders where the three on-board pressure sensors are located, so that the three air cylinders sequentially release pressure through the detection port 803 and the air circuit switching valve 15 to the pipeline where the main sensor 10 is located, and the pressures of the three air cylinder terminal nodes are obtained in turn through the main sensor 10.

[0036] Due to the frequent air supply from the air source, a great impact will be caused on the pipelines and sensors. Therefore, a pressure-maintaining cylinder 14 is provided in the outer shell 1. The pressure-maintaining cylinder 14 is connected between the main air control valve and the air circuit switching valve 15. A pressure relief valve 7 is provided on one side of the outer shell 1 corresponding to the pressure-maintaining cylinder 14. The pressure relief valve 7 is connected to the pressure-maintaining cylinder 14 and is used to relieve the pressure of the pressure-maintaining cylinder 14.

[0037] The use of the pressure-maintaining cylinder 14 can significantly reduce the impact of the gas source on the valve and sensor components during gas supply, thereby achieving a pressure and flow stabilization effect, thereby improving the accuracy and reliability of the detection data.

[0038] At the same time, in another optional method, the pressure-maintaining cylinder 14 can be used to stabilize the pressure of the air cylinder where the vehicle-mounted pressure sensor is located when the pressure is released, so as to improve the detection accuracy of the main sensor 10 for the pressure of the three air cylinder terminal nodes.

[0039] Furthermore, the detection quick-action interface 8 also includes an air vent 804, which is connected to the air path switching valve 15. The air vent 804 is used to vent the air pressure of the device to avoid interference with the next detection, thereby realizing rapid switching detection of multiple gears.

[0040] Reference Figure 3-4 A EMU brake pressure intelligent debugging system includes at least one EMU brake pressure intelligent debugging device as described above. The debugging system includes: an information acquisition module, the information acquisition module is connected to the debugging device, specifically by communication connection or data line transmission, the information acquisition module is connected to the train BCU and is used to intercept data of the BCU corresponding to the debugging device, the intercepted data is transmitted to the debugging device, and the data is stored in a storage unit.

[0041] It also includes a calculation module, which is used to read the storage unit data in the debugging device and calculate the pressure values ​​of the brake cylinder pressure sensor, train pipe pressure sensor, total air pressure sensor, parking brake cylinder pressure sensor and auxiliary air cylinder pressure sensor.

[0042] The calculation module can cooperate with the main sensor 10 to calculate and obtain theoretical values, thereby facilitating the subsequent comparison module to perform comparison.

[0043] It also includes a comparison module, which is used to compare the time axis pressure value curve calculated by the main sensor 10 data / calculation module with the time axis pressure value curve of the sensor intercepted from the BCU, thereby forming a chart to facilitate subsequent judgment of the system status. At the same time, the comparison module can judge the data difference, thereby realizing the detection of sensor accuracy.

[0044] Specifically, in this embodiment, the display module is a display screen 4 mounted on the housing 1 to facilitate operators to view the detection results in real time.

[0045] Among them, when the operator inspects multiple carriages at the same time, multiple network communication devices communicate with each other to form a local area network group. The local area network is used for communication between debugging devices and between debugging devices and information acquisition modules, thereby facilitating the aggregation and export of data to avoid data loss.

[0046] Reference Figure 5 , an intelligent debugging method for brake pressure of a train set, applied to the debugging system as described above, for performing pressure adjustment detection on the train, the debugging method comprises: S1. The air source supplies air pressure to the air circuit switching valve 15 according to the standard air pressure required for the debugging gear position. At this time, the main sensor 10 detects the size of the supplied air pressure and the size of the total air cylinder pressure. At the same time, the information acquisition module obtains the total air cylinder pressure value corresponding to the BCU. Since the train is in a cold state, there is still a certain air pressure in the total air cylinder. Therefore, the main sensor 10 is used in conjunction with the information acquisition module to complete the detection of the initial pressure value in the total air cylinder.

[0047] S2. Switch the air circuit switching valve 15 so that the air source supplies air pressure to the pressure regulating port 802. The pressure regulating valve 12 adjusts the air pressure supplied to the relay valve to the control air pressure required for the gear to be tested. The pressure regulating sensor records the supply air pressure value in real time. At the same time, the information acquisition module obtains the total air cylinder and pre-control pressure values ​​corresponding to the BCU in real time. By supplying pressure to the relay valve and obtaining the change in the pressure value before and after the total air cylinder is supplied with pressure, the theoretical pressure value and the actual pressure value in the total air cylinder can be obtained, so as to complete the debugging of the total air cylinder pressure switch 3 under the brake gear according to the value.

[0048] S3. Cut off the main air control valve and switch the air circuit switching valve 15 to connect with the detection port 803. Specifically, since the number of detection ports 803 is 3, the six-way valve is switched to connect with the three detection ports 803 in turn, so that the corresponding cylinders of the brake pressure (C), the backup brake pre-control pressure sensor (STV), and the air spring pressure sensor (T) respectively discharge air to the six-way ball valve, and the main sensor 10 records the brake pressure (C), the backup brake pre-control pressure sensor (STV), and the air spring pressure sensor (T) The air cylinder air pressure value, at the same time, the information acquisition module obtains the recorded values ​​of the corresponding sensors from the BCU.

[0049] S4. The calculation module calculates the theoretical pressure values ​​of the brake cylinder pressure sensor, train pipe pressure sensor, total wind pressure sensor, parking brake cylinder pressure sensor, and auxiliary air cylinder pressure sensor according to the air cylinder air pressure value of the vehicle-mounted pressure sensor position recorded by the main sensor 10. At the same time, the information acquisition module obtains the recorded values ​​of the BCU corresponding sensors.

[0050] Specifically, the conversion formula corresponding to the calculation module is:

[0051]

[0052]

[0053] Wherein, x is the input pressure value, which in this embodiment is specifically the supply air pressure value recorded by the pressure regulating sensor.

[0054] S5. Reopen the main air control valve, supply corresponding air pressure to the air circuit switching valve 15 according to the air pressure required for another gear of the braking system and the changing air pressure during gear switching and shaking, and repeat steps S1-S4 until all gears are debugged.

[0055] S6. The debugging device receives data from the information acquisition module in real time, and the comparison module automatically draws the time axis pressure value curve calculated by the main sensor 10 data / calculation module in the debugging device and the time axis pressure value curve of the sensor intercepted from the BCU to form a comparison chart, automatically calculates the accuracy and response speed of each vehicle-mounted sensor, and automatically generates chart data.

[0056] S7. The debugging device determines the abnormal working state of the sensor according to the comparison chart.

[0057] S8. Data is aggregated between multiple debugging devices through networking interaction transmission, so as to aggregate the data on other debugging devices into a single debugging device.

[0058] Specifically, when there are multiple debugging devices in the system, a local area network is formed between the multiple debugging devices. Before a single debugging device is shut down, it automatically searches for other online debugging devices through the network communication component to send data to other devices. Only when the data of all debugging devices are summarized in a single communication unit can the subsequent shutdown steps be performed. When the transmission is not successful, the alarm component sounds an alarm to remind the operator to avoid data loss, thereby cooperating with the above-mentioned debugging system to realize automatic data identification, automatic induction, automatic tabulation, and automatic uploading. Through data interaction before shutdown, data loss is effectively avoided, and the accuracy and reliability of debugging data are guaranteed.

[0059] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
