DETAILED DESCRIPTION

[0025] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] For example, see Figure 1-3The present invention provides a technical solution: an intelligent testing system for a train in a braking state, comprising a data input module, a data acquisition module, a handheld monitoring module and a terminal monitoring module, for collecting and analyzing pressure data in a train in a braking state to ensure that the train brakes normally when in use.

[0027] The data input module is used to connect to the pressure test port of each corresponding carriage to obtain the pressure data under the braking state of the train; it is usually set to connect to the pressure test port of the BCU (Brake Control Unit) box. The BCU is a brake control unit, which is used to control the braking system of the train, mainly by receiving brake signals, speed signals and load signals, and outputting corresponding brake mode signals.

[0028] The data acquisition module is signal-connected to the above-mentioned data input module and is used for pressure data acquisition in the corresponding braking mode. The data acquisition module is signal-connected to a collector 1. The collector 1 needs to be paired with a corresponding charger. The collector 1 is preferably an air pressure tester. Specifically, a plurality of pipe interfaces 2 are provided on the top of the surface of the collector 1. The plurality of pipe interfaces 2 are used to be connected to the pressure test port of the corresponding carriage through a pipe. A first antenna 3 is provided on both sides of the collector 1 for enhancing the wireless signal output.

[0029] The handheld detection module is used to detect the signal transmission status in the data acquisition module. The handheld detection module signal is connected to a handheld device, which is not shown in the figure. The handheld device also needs to be equipped with a charger. The working voltage is set to 3.7 volts and it has its own lithium battery for charging. The handheld device is connected to a second antenna for easy wireless signal reception.

[0030] The terminal monitoring module is connected to the handheld detection module signal. The terminal monitoring module is used to monitor the entire test process, determine the accuracy of the test process, and summarize the results obtained from each car after the test to determine whether the train's braking is normal, so as to improve the train's braking safety.

[0031] Specifically, the data input module includes a connection confirmation unit and a position selection unit, wherein the connection confirmation unit is used to determine that the pipeline interface 2 completes the connection of the corresponding pressure test port, and the position selection unit is used to determine the vehicle information. Further, the position selection is used to select vehicle data on the test software at the handheld device. Exemplarily, the vehicle data includes the test model, the main control vehicle, the test compartment, the selected equipment and the vehicle number. After the selection is completed, the test system is entered by clicking OK to effectively collect and record the corresponding test data of the vehicle;

[0032] The data acquisition module includes an air pressure monitoring unit and an electric quantity monitoring unit. The electric quantity monitoring unit is used for pre-detection of the electric quantity of the collector 1. Therefore, in the use requirements, if the test process is carried out, it is necessary to ensure that the electric quantity of the collector 1 is sufficient. The air pressure monitoring unit is used for real-time monitoring of the obtained pressure data during the pressure test under the braking state, and can be fed back to the terminal monitoring module;

[0033] The handheld detection module includes a gear determination unit and a result generation unit. The gear determination unit is used to set a brake test for multiple gears, including but not limited to EB electric-pneumatic composite emergency brake, UB pure air emergency brake, and FSB maximum common braking mode. The result generation unit is used to form a report of the test result and transmit it to the terminal monitoring module;

[0034] The terminal monitoring module includes a data receiving unit, an accurate analysis unit, and an alarm transmission unit. The data receiving unit is used to summarize and receive the measured pressure data. The accurate analysis unit can compare and analyze the measured pressure data, and determine whether there is a braking problem through abnormal pressure data. The alarm transmission unit is used to issue an alarm for abnormal pressure problems, alerting the staff to conduct separate inspections on the abnormal carriages to ensure the safety of the train carriages during the braking process.

[0035] After the handheld device is turned on, the corresponding test software is set on its display screen, which is convenient for manually clicking the process and collecting the measured pressure data.

[0036] In this embodiment, the first step is to take out the collector 1 required for the test and turn on the first antenna 3, and long press the power for the set time to turn on the machine. The normal state of the collector 1 is determined by the flashing of the status light, and the sufficient power is determined by the color of the power light. For example, if the status light keeps flashing, the device is normal, if the power light is constant green, it means the power is sufficient, and if the power light is red, it means the power is insufficient.

[0037] Additionally, keep the handset powered on with its second antenna switched on;

[0038] The second step is to open the desktop icon of the handheld device in a pre-set manner, which may be long pressing a key with other functions or a dedicated start button;

[0039] The third step is to input vehicle information through the desktop icon, select the current test model, main control vehicle, test compartment, selected equipment, and enter the vehicle number, and click OK to enter the test interface;

[0040] The fourth step is to install the collector 1. Place it in the BCU box of the corresponding carriage according to the number of the collector 1. After entering the test interface, under the connection of the pipeline interface 2, the test interface can connect the pipeline interface 2 corresponding to the collector 1 with the corresponding BCU box pressure test port. Among them, the pipeline interface 2 can be marked as CH01-CHi, i is 02-n, and n is the total number of pipeline interfaces 2. Figure 3 , the pipe interface 2 can be marked as CH01-CH05, and the corresponding BCU box pressure test port marking setting can also be associated with the vehicle data to facilitate the rapid positioning of the carriage and the pressure test port when generating reports;

[0041] Step 5: Select the brake gear and start collecting data. The test interface is set with test mode selection, including but not limited to EB electric-pneumatic composite emergency brake, UB pure air emergency brake, and FSB maximum common brake mode. In addition, before data collection, refresh through the "refresh data" set in the test interface to obtain pressure data and power data presented in data form;

[0042] Step 6. Place the brake handle on the brake gear that currently corresponds to the test interface and wait for the data to be displayed. After confirming that the data is correct, continue to select other brake gears at the bottom of the screen and repeat the operation until the test is completed.

[0043] After all the operations are completed, click the "Generate Report" button set at the bottom of the screen to save the report in the handheld test software folder and transfer it to the background monitoring module;

[0044] Step 7: Collect the data of collector 1 and the handheld device and execute the shutdown procedure in order. The back-end performs comparative analysis on the pressure data of the report.

[0045] Example 2, reference Figure 4-Figure 8 , the following mechanism is added on the basis of the first embodiment:

[0046] A base 4 is provided below the collector 1 for supporting and fixing the collector 1. A mounting plate 5 is provided between the base 4 and the collector 1 for fixing the collector 1. A plurality of gravity sensing parts 6 are supported and connected between the base 4 and the mounting plate 5. For example, four gravity sensing parts 6 are provided, which are respectively fixedly connected to the four corners of the mounting plate 5 for collecting gravity data at each corner to determine whether the mounting plate 5 is in a stable installation state.

[0047] like Figure 4 As shown, a mounting groove matching the bottom of the collector 1 is provided in the middle of the upper surface of the mounting plate 5, and a fixing portion 7 is fixedly connected to one side of the mounting groove. The fixing method includes but is not limited to a threaded connection. The fixing portion 7 is in contact with a side of the collector 1 where the first antenna 3 is provided.

[0048] like Figure 5-Figure 6 As shown, a support plate 11 is fixed at the other side of the fixing part 7 and the collector 1 where the first antenna 3 is provided, and the fixing method includes but is not limited to an integrated setting with one side of the mounting plate 5, welding, etc., the middle part of the support plate 11 is fixedly connected with an electric control driving part 12, and the output end of the electric control driving part 12 is transmission-connected with a first transmission part 15, the first transmission part 15 can be composed of a gear set with a certain transmission ratio and a first conveyor belt, the output end of the first transmission part 15 is connected with a central shaft 18 through a key, the end of the central shaft 18 close to the collector 1 is fixedly connected with a central gear 17, the outer surface of the central gear 17 is connected with a second transmission part 16 through a gear transmission, and the second transmission part 16 can be composed of a second conveyor belt and gears of the same size arranged at both ends of the second conveyor belt;

[0049] The two ends of the second transmission part 16 are connected to the rotating rod 13, and the rotating rod 13 and the central axis 18 are rotatably connected to the ear seat on the upper surface of the mounting plate 5. The ear seat is fixedly mounted on the mounting plate 5, and one end of the rotating rod 13 and the central axis 18 is connected to the support plate 11 with a bearing;

[0050] A slide groove 14 is correspondingly provided on the upper surface of the mounting plate 5 near the rotating rod 13. The other end bearing of the rotating rod 13 is connected to the inside of the slide groove 14, and the outer surface of the rotating rod 13 located inside the slide groove 14 is provided with the same thread. A fixed adjustment part 19 is rotatably connected to the surface of the rotating rod 13 located at the slide groove 14. After the installation of the collector 1 is completed, the other side of the collector 1 is clamped and fixed to achieve the predetermined installation of the collector 1 in the mounting plate 5.

[0051] like Figure 7 As shown, the base 4 is provided with a corresponding storage groove 21 on the upper surface of one side close to the gravity sensor 6 for the regular placement of the wire body;

[0052] like Figure 8 As shown, a magnetic attraction portion 20 is provided at the bottom of the base 4. By energizing the setting, the magnetic attraction portion 20 drives the entire base 4 and the collector 1 to be fixed at the connection. A starting switch is also provided for energizing the setting. It should be noted that the connection is made of a magnet-attractive material. Otherwise, a number of threaded connectors can also be provided on the surface of the base 4 to achieve the fixation of the base 4, which will not be elaborated here.

[0053] Furthermore, a support rod is installed through the surface of the mounting plate 5 close to the support plate 11 , and a support spring is installed and wound around the surface of the support rod below the mounting plate 5 to improve the support stability of the mounting plate 5 .

[0054] In this embodiment, when executing the fourth step, the installation structure in this embodiment is adopted. Specifically, the base 4 and the structure installed above it are pre-installed in the BCU box. The base 4 is fixed by starting and energizing the magnetic attraction part 20. The collector 1 is first placed in the installation slot and abutted against the fixing part 7. Finally, the electric control driving part 12 is started to set the time. Under the action of the first transmission part 15 and the second transmission part 16, the rotating rod 13 rotates to drive the fixing adjustment part 19 to move toward the collector 1 and completes the clamping of the collector 1 body through the cooperation with the fixing part 7.

[0055] After that, adjust the angle of the first antenna 3, and then connect the pipeline interface 2 and the test pressure port in turn. First, the above fixing method of the collector 1 is simple. Secondly, through the gravity sensor 6 set at the bottom, not only the placement level of the collector 1 is detected, but also the overall vibration condition can be monitored during the test process performed in the sixth step;

[0056] It should be noted that when executing the fourth step, the gravity sensing unit 6 is connected to the terminal monitoring module through the data acquisition module. When the handheld device is turned on, the handheld detection module will obtain data feedback from the terminal monitoring module. For example, based on the position setting of the gravity sensing unit 6 in this embodiment, it will be determined whether the collector is in a horizontal state based on the collected gravity data, thereby improving the measurement accuracy. Specifically, the four sets of initial gravity data actually collected are displayed on a three-dimensional coordinate model, with the x and y coordinates being consistent, and only the z coordinate value is obtained. The displayed model is displayed in the handheld device, and the horizontal state of the collector 1 can be quickly obtained. If there is a large deviation, the collector 1 will be replaced immediately while ensuring that other structures are correct, to ensure the accuracy of subsequent detection data.

[0057] When executing pressure data collection in each mode, the vibration condition of the collector 1 body is judged by the floating interval of gravity data. Specifically, taking this technical solution as an example, the initial gravity data is recorded as f j , real-time gravity data is recorded as F j , j is an integer from 1 to 4, which is the mark number of the gravity sensor part 6, indicating the initial and real-time gravity data of the four groups of gravity sensor parts 6. The real-time gravity data changes in real time during the test. The data acquisition module collects the gravity data and calculates the vibration value F through the accurate analysis unit. Z , , Indicates that during the test, the jth gravity sensor 6 takes the maximum gravity difference from the initial gravity data, and the vibration value F ZIt is the sum of the maximum gravity difference values ​​measured by all gravity sensing parts 6. The vibration condition value range corresponding to different levels of vibration is input in advance in the handheld device or the back end, thereby obtaining the vibration condition corresponding to the collector 1. While determining that the measured pressure data is inaccurate, the quality of the collector 1 itself is judged. Through the result feedback of the handheld device, the collector 1 with abnormal vibration is stopped from working, and the collector 1 is replaced and marked for subsequent problem inspection.

[0058] Example 3, reference Figure 4 as well as Figure 7 , the following structure is added on the basis of the second embodiment:

[0059] The base 4 is located on both sides of the collector 1 and is fixedly installed with a bracket group 8. The bracket group 8 is fixedly connected to a plurality of electrically controlled telescopic parts 9 on one side facing the pipe interface 2. The number of electrically controlled telescopic parts 9 on both sides is consistent with the number of pipe interfaces 2, and the output ends of the electrically controlled telescopic parts 9 on both sides are respectively connected with a sub-cover 101 and a main cover 102 that are connected to each other. The sub-cover 101 and the main cover 102 constitute an auxiliary cover 10, which can be sleeved on the outer circle position of the pipe interface 2 to monitor leakage under brake pressure test. Specifically, the inner walls of the sub-cover 101 and the main cover 102 are provided with sensing plates 103 near the upper and lower interfaces of the pipe, and the inside of the sensing plate 103 is provided with a pressure sensing sheet for monitoring the airflow pressure at the interface where leakage problems may exist, so as to find the problem more quickly when abnormal pressure data appears.

[0060] In addition, a flow passage 104 is installed in the middle of the inner wall of the sub-cover 101 and the main cover 102. The flow passage 104 is arranged to penetrate and protrude from the inner wall and the outer wall of the auxiliary cover 10. The flow passage 104 protrudes from the outer ring surface of the inner wall of the auxiliary cover 10 and is provided with a plurality of air holes in a ring shape. A ventilation flow channel is arranged inside the flow passage 104. One end of the ventilation flow channel is communicated with the plurality of air holes. The flow passage 104 is located on the protruding outer surface of the outer wall of the auxiliary cover 10 and is fixed to the output end of the adjacent electric control telescopic part 9. The other end of the ventilation flow channel extends to the protruding part of the outer wall of the auxiliary cover 10 where the flow passage 104 is located and is connected to an air pump through a hose. The air pump is arranged separately and is not shown in the figure. The output end of the air pump can be connected to all hoses through a pipeline connection. The collector 1 is cleaned and decontaminated before or after use.

[0061] In this embodiment, the induction board 103 is connected to the data acquisition module signal. When the collector 1 is installed and clamped in the installation slot, the sub-cover 101 and the main cover 102 are separated. After the installation of the collector 1 is completed, the air pump is started and blows up the area near the pipeline interface 2 through the air hole to remove impurities, and then the pipeline of the pressure test port is connected. After that, the electric control telescopic part 9 is started to make the sub-cover 101 and the main cover 102 clamped and form an auxiliary cover 10 structure;

[0062] During the execution of the sixth step, the sensing plate 103 arranged on the inner wall of the auxiliary cover 10 can perform a gas leakage test on the interface position. Through the setting of the auxiliary cover 10, a relatively windless environment is formed at the upper and lower interfaces of the pipeline interface. During the pressure test process under the braking state, the sensing plate 103 performs leakage detection on the leakage airflow to ensure the accuracy of the pressure data measured by the collector 1. If the sensing plate 103 measures the pressure exerted by the leaking gas, the above pressure test is suspended and the connection at the pipeline interface 2 is adjusted. The gas leakage position can also be quickly obtained by marking the sensing plate 103 in advance.

[0063] In addition, the data acquisition module improves the accuracy of pressure data acquisition through the above-mentioned vibration conditions and the gas leakage conditions in this example, and can monitor the quality problems of the collector 1 itself and the connection problems at the pipeline interface 2 in real time. In addition, when abnormal conditions occur, the corresponding problems of the collector 1 can be directly obtained, saving troubleshooting time.

[0064] During the seventh step of taking out, the air pump can be started again to remove the debris on the surface of the collector 1 to facilitate the packing of the collector 1.
