[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0046] Example 1
[0047] This embodiment provides a car wash machine's obstacle avoidance device for EMU bogies. This device is applied in the cleaning of passenger cars, EMUs, subways, and other transportation vehicles, enabling the car wash machine to avoid the EMU bogies when cleaning them. Each car of the EMU is equipped with two EMU bogies, which are located on both sides along the length of the car.
[0048] As shown in Figure 1, the car wash machine for cleaning high-speed trains includes several bottom skirt brushes 500 and several side brushes 600 arranged sequentially along the length of the track 400 on the sides of the track 400. The side brushes 600 are used to clean the carriages of the high-speed train, and the bottom skirt brushes 500 are used to clean the bottom skirts of the high-speed train. The number of bottom skirt brushes 500 can be set to one, two, three, or more, depending on the cleaning requirements. The number of side brushes 600 can also be set to one, two, three, or more, depending on the cleaning requirements.
[0049] As shown in Figure 2, the avoidance device includes a proximity sensor 100 and a control module 200. The proximity sensor 100 is installed on the side of the track 400 and at least at a preset position in front of the corresponding bottom skirt brush 500, and is used to detect the position of the train bogie. As one example, the proximity sensor 100 is located at a preset position in front of the corresponding bottom skirt brush 500; as yet another example, the proximity sensor 100 is located at preset positions both in front of and behind the corresponding bottom skirt brush 500.
[0050] Compared to optical sensors, proximity sensors 100 are less affected by the external environment, especially by water and oil. Even when the car wash machine is operating in a wet environment, it can still ensure detection accuracy, enabling the underskirt brush 500 to effectively avoid collisions with the bogie.
[0051] Among them, the distance between the proximity sensor 100 and the corresponding bottom skirt brush 500 is mainly related to the distance between the front wheelset 710 and the rear wheelset 720 of the train bogie 700.
[0052] The control module 200 is electrically connected to the proximity sensor 100 and is used to control the start and stop of the corresponding bottom skirt brush 500 based on the detection results sent by the proximity sensor 100, so that the corresponding bottom skirt brush 500 avoids the train bogie. When the proximity sensor 100 detects the train bogie passing by, the control module 200 disconnects the path of the corresponding bottom skirt brush 500, causing the corresponding bottom skirt brush 500 to stop rotating. This avoids the train bogie from continuing to rotate while the train bogie is passing by, which not only avoids damage to the cables at the train bogie, but also avoids corrosion of the train bogie by detergent.
[0053] As can be seen, the avoidance device provided in this embodiment can enable the bottom skirt brush 500 to avoid the train bogie through the cooperation of the proximity sensor 100 and the control module 200. This not only avoids damage to the cables at the train bogie 700, but also prevents detergent from corroding the train bogie 700.
[0054] In this embodiment, the proximity sensor 100 can be disposed on the inner side of the track 400. Compared to being disposed on the outer side of the track 400, being disposed on the inner side of the track 400 makes it easier to detect wheels with a large right angle at the rim.
[0055] The track 400 can be either 50 or 60 rails. It should be noted that 50 rails refer to rails weighing 50 kg / m, and 60 rails refer to rails weighing 60 kg / m.
[0056] In this embodiment, multiple proximity sensors 100 are configured, and these sensors 100 are divided into several groups along the length of the track 400. Each group can have one proximity sensor 100, which saves costs. Alternatively, each group can have two proximity sensors 100, arranged opposite each other along the width of the track 400, with one proximity sensor at each rail of the track 400. This ensures that if one proximity sensor 400 fails, the other can continue operating, guaranteeing precise avoidance of the bogie 700. It is understood that the distance from each group of proximity sensors 100 to the corresponding bottom skirt brush 500 is the same. When any proximity sensor 100 in each group detects the passing of the bogie, the control module 200 controls the corresponding bottom skirt brush 500 to stop rotating, allowing the bottom skirt brush 500 to avoid the bogie.
[0057] Example 2
[0058] This embodiment provides a vehicle wash machine obstacle avoidance device for train bogies. Compared with the obstacle avoidance device provided in Embodiment 1, in this embodiment, specifically, when the proximity sensor 100 detects different front and rear wheelsets of the train bogie 700, it can alternately send a first detection result and a second detection result; the control module 200 can switch or maintain the state of the corresponding underside brush 500 based on the first and second detection results; wherein, the detection results include the first detection result and the second detection result, and the state of the corresponding underside brush 500 includes an on state and a off state. The control module 200 can determine the current state of the corresponding underside brush 500 according to the first and second detection results sent by the proximity sensor 100, which facilitates the control of the start and stop of the corresponding underside brush 500.
[0059] Specifically, in this embodiment, multiple proximity sensors 100 are provided, with proximity sensors 100 positioned at preset locations in front of and behind the bottom skirt brush 500. When the proximity sensor 100 in front of the bottom skirt brush 500 detects the passage of the front wheelset 710 of the bogie 700, it can send a first detection result. Based on the first detection result sent by the front proximity sensor 100, the control module 200 can switch the state of the corresponding bottom skirt brush 500 from an open state to a closed state. When the proximity sensor 100 in front of the bottom skirt brush 500 detects the passage of the rear wheelset 720 of the bogie 700, it can send a second detection result. Based on the first detection result sent by the front proximity sensor 100, the control module 200 can switch the state of the corresponding bottom skirt brush 500 from an open state to a closed state. The control module 200 maintains the current state of the corresponding underside brush 500 by sending the second detection result. When the proximity sensor 100 behind the corresponding underside brush 500 detects the passage of the front wheelset 710 of the bogie 700, it can send the first detection result. Based on the first detection result sent by the rear proximity sensor 100, the control module 200 can switch the state of the corresponding underside brush 500 from the off state to the on state. When the proximity sensor 100 behind the corresponding underside brush 500 detects the passage of the rear wheelset 720 of the bogie 700, it can send the second detection result. Based on the second detection result sent by the rear proximity sensor 100, the control module 200 maintains the current state of the corresponding underside brush 500.
[0060] When the front proximity sensor 100 and the rear proximity sensor 100 detect the front wheelset 710 of the bogie 700, both the front and rear proximity sensors 100 send a first detection result, such as outputting a "1" level in digital form. When the front and rear proximity sensors 100 detect the rear wheelset 720 of the bogie 700, both the front and rear proximity sensors 100 send a second detection result, such as outputting a "0" level in digital form. The front wheelset 710 and the rear wheelset 720 can be distinguished by the first and second detection results, which can effectively determine the position of the bogie 700. The control module 200 can also determine the state of the underside brush 500 according to the type of detection result, so that the corresponding underside brush 500 can effectively avoid the bogie 700.
[0061] Specifically, when the proximity sensor 100 behind the corresponding bottom skirt brush 500 detects the front wheel set 710 of the train bogie 700, the control module 200 switches the state of the corresponding bottom skirt brush 500 from the off state to the on state. At this time, in order to ensure that the corresponding bottom skirt brush 500 can avoid the train bogie 700, the rear wheel 720 of the train bogie 700 should be located behind the bottom skirt brush 500. This means that the distance from the corresponding bottom skirt brush 500 to the proximity sensor 100 behind it must be at least equal to the distance from the train bogie 710 to the rear wheel set 710. Considering that the response time of the proximity sensor 100 and the start-up time of the corresponding underside brush 500 are both in the millisecond range, the distance from the corresponding underside brush 500 to the rear proximity sensor 100 is slightly greater than the distance between the front wheel pair 710 and the rear wheel pair 720 of the bogie 700. Similarly, the distance from the corresponding underside brush 500 to the front proximity sensor 100 can also be slightly greater than the distance between the front wheel pair 710 and the rear wheel pair 720 of the bogie 700.
[0062] The obstacle avoidance device provided in this embodiment can be applied to both situations where the train bogie 700 is traveling at a constant speed and situations where the train bogie 700 is traveling at a non-constant speed.
[0063] Figure 3 illustrates a car wash line, suitable for both bidirectional and unidirectional car washing. Each station (G09, G12, G13, G14, G16, and G18) is equipped with a skirt brush 500, and each station (A1, A2, A3, A4, A5, A6, A7, A8, and A9) is equipped with a proximity sensor 100. The proximity sensors 100 at stations A1 and A2 correspond to the skirt brush 500 at station G09, and the proximity sensors 100 at stations A3 and A5... The proximity sensor 100 corresponds to the bottom skirt brush 500 at station G12; the proximity sensor 100 at stations A4 and A6 corresponds to the bottom skirt brush 500 at station G13; the proximity sensor 100 at stations A5 and A7 corresponds to the bottom skirt brush 500 at station G14; the proximity sensor 100 at stations A7 and A8 corresponds to the bottom skirt brush 500 at station G16; and the proximity sensor 100 at stations A8 and A9 corresponds to the bottom skirt brush 500 at station G18.
[0064] The following describes how the underside brush 500 group, as shown in Figure 3, avoids the bogie 700: When the proximity sensor 100 at station A1 detects the passage of the front wheel pair 710 of the bogie 700, it outputs a "1" level digitally (i.e., the first detection result), and the control module 200 controls the underside brush 500 at G09 to stop rotating; when the proximity sensor 100 at station A1 detects the passage of the rear wheel pair 720 of the bogie 700, it outputs a "0" level digitally (i.e., the second detection result), and the control module 200 controls the underside brush 500 at G09 to remain stationary, i.e., maintain... The current state is as follows: When the proximity sensor 100 at station A2 detects the passage of the front wheel pair 710 of the bogie 700, it outputs a "1" level in digital form (i.e., the first detection result), and the control module 200 controls the bottom skirt brush 500 at G09 to start rotating; when the proximity sensor 100 at station A2 detects the passage of the rear wheel pair 720 of the bogie 700, it outputs a "0" level in digital form (i.e., the second detection result), and the control module 200 controls the bottom skirt brush 500 at G09 to remain stationary, thus maintaining the current state; and so on, to complete the avoidance of the bogie by the bottom skirt brush 500 group.
[0065] In this embodiment, as shown in FIG4, when the wheelset of the train bogie 700 passes the proximity sensor 100, the probe of the proximity sensor 100 points to the edge of the wheelset, which can improve the detection accuracy of the proximity sensor 100.
[0066] Example 3
[0067] As shown in Figure 5, this embodiment provides a car wash machine to avoid a train bogie. Compared with the avoidance device provided in Embodiment 2, the avoidance device provided in this embodiment only sets a proximity sensor 100 in front of the corresponding bottom skirt brush 500, and enables the control module 200 to have a timing function. The way the proximity sensor 100 and the control module 200 cooperate is also different.
[0068] Specifically, in this embodiment, when the proximity sensor 100 in front of the corresponding bottom skirt brush 500 first detects the wheelset of the train bogie, it can send a detection result; the control module 200 can switch the corresponding bottom skirt brush 500 from an on state to a off state based on the detection result; the control module 200 can also start a timer when the corresponding bottom skirt brush 500 switches from an on state to a off state, and switch the corresponding bottom skirt brush 500 from an off state to an on state when the timer reaches a preset duration. This configuration also allows the control module 200 to control the start and stop of the corresponding bottom skirt brush 500, so that the corresponding bottom skirt brush 500 avoids the train bogie.
[0069] The preset duration is mainly related to the distance L1 between the corresponding underside brush 500 and the front proximity sensor 100, and the distance L2 between the front wheelset 710 and the rear wheelset 720 of the bogie 700. As an example, the preset duration can be calculated using the following formula:
[0070] t=(L1+L2) / V
[0071] In the formula: t is the preset duration; V is the speed of the train bogie at 700.
[0072] The distance L1 between the bottom skirt brush 500 and the front proximity sensor 100 can be determined according to the method of Embodiment 2.
[0073] The obstacle avoidance device provided in this embodiment is applicable to situations where the bogie of a high-speed train is traveling at a constant speed of 700.
[0074] Example 4
[0075] This embodiment provides a method for a car wash machine to avoid a train bogie. The car wash machine includes a plurality of bottom skirt brushes 500 arranged along the length of the track 400 on the side of the track 400, as shown in Figure 6. The avoidance method includes:
[0076] Step S100: Detect the position of the train bogie 700 at least at a preset position in front of the corresponding bottom skirt brush 500 and send the detection result;
[0077] Step S200: Based on the detection results, control the start and stop of the corresponding bottom skirt brush 500 so that the corresponding bottom skirt brush 500 avoids the train bogie 700.
[0078] For step S100, the execution subject of this step is the proximity sensor 100 in Embodiment 1, Embodiment 2, or Embodiment 3. That is, the proximity sensor 100 is set at a preset position in front of the corresponding bottom skirt brush 500 and the position of the train bogie 700 is detected by the proximity sensor 100. Specifically, the proximity sensor 100 is either set at a preset position in front of the corresponding bottom skirt brush 500; or the proximity sensor 100 is set at preset positions both in front of and behind the corresponding bottom skirt brush 500.
[0079] Compared to optical sensors, proximity sensors 100 are less affected by the external environment, especially by water and oil. Even when the car wash machine is operating in a wet environment, it can still ensure detection accuracy, enabling the underskirt brush 500 to effectively avoid collisions with the bogie 700.
[0080] The process from receiving a signal to outputting a signal by the proximity sensor 100 requires a certain amount of time (i.e., response time). During this process, the train bogie 700 moves continuously along the track 400. In order to ensure that the corresponding bottom skirt brush 500 stops rotating as soon as the train bogie 700 reaches it, in this embodiment, the proximity sensor 100 is set at a preset position in front of the bottom skirt brush 500. This allows for a certain distance for the response of the proximity sensor 100. After the proximity sensor 100 has finished responding, the train bogie 700 has just reached the corresponding bottom skirt brush 500.
[0081] Regarding step S200, the executing entity for this step is the control module 200 in Embodiment 1, Embodiment 2, or Embodiment 3. Specifically, based on the detection results, the control module 200 controls the start and stop of the corresponding bottom skirt brush 500 to ensure that the corresponding bottom skirt brush 500 avoids the train bogie 700. When the proximity sensor 100 detects the train bogie 700 passing by, the control module 200 disconnects the path of the corresponding bottom skirt brush 500, causing the corresponding bottom skirt brush 500 to stop rotating. This allows it to avoid the train bogie 700, preventing it from continuing to rotate while the train bogie 700 is passing by. This not only avoids damage to cables at the train bogie 700 but also prevents detergent from corroding the train bogie 700.
[0082] As can be seen, the avoidance method provided in this embodiment enables the bottom skirt brush 500 to avoid the train bogie 700, which not only avoids damage to the cables at the train bogie 700, but also avoids the detergent from corroding the train bogie 700.
[0083] Example 5
[0084] This embodiment provides a method for a car wash machine to avoid a train bogie 700. Compared with the avoidance method provided in Embodiment 4, step S200 of this embodiment may specifically include: when different wheelsets of the bogie are detected passing by, alternately sending a first detection result and a second detection result; wherein, the detection result includes the first detection result and the second detection result; step S230 may specifically include: based on the first detection result and the second detection result, switching or maintaining the state of the corresponding underside brush 500; wherein, the state of the corresponding underside brush 500 includes an open state and a closed state. The avoidance method provided by this embodiment can determine the current state of the corresponding underside brush 500 according to the first detection result and the second detection result sent by the proximity sensor 100, which facilitates the control of the start and stop of the corresponding underside brush 500.
[0085] Furthermore, in this embodiment, step S200 may include the following:
[0086] Step S210: When the front wheel pair 710 of the train bogie 700 is detected passing at a preset position in front of the corresponding bottom skirt brush 500, the first detection result is sent.
[0087] Step S220: When the rear wheel pair 720 of the train bogie 700 is detected to pass through at a preset position in front of the corresponding bottom skirt brush 500, the second detection result is sent.
[0088] Step S230: When the front wheel pair 710 of the train bogie 700 is detected passing at a preset position behind the corresponding bottom skirt brush 500, the first detection result is sent.
[0089] Step S240: When the rear wheel pair 720 of the train bogie 700 is detected to pass through at a preset position behind the corresponding bottom skirt brush 500, the second detection result is sent.
[0090] Correspondingly, step S300 may include the following steps:
[0091] Step S310: Based on the first detection result sent in front of the corresponding bottom skirt brush 500, switch the state of the corresponding bottom skirt brush 500 from the open state to the closed state;
[0092] Step S320: Based on the second detection result sent in front of the corresponding bottom skirt brush 500, maintain the state of the corresponding bottom skirt brush 500;
[0093] Step S330: Based on the first detection result sent behind the corresponding bottom skirt brush 500, switch the state of the corresponding bottom skirt brush 500 from the closed state to the open state;
[0094] Step S340: Based on the second detection result sent after the corresponding bottom skirt brush 500, maintain the state of the corresponding bottom skirt brush 500.
[0095] It should be noted that steps 210, 310, 220, 320, 230, 330, 240, and 340 are performed sequentially. When the front wheelset 710 of the bogie 700 is detected passing in front of the corresponding bottom skirt brush 500, a first detection result is sent, for example, a digital output of a "1" level. When the rear wheelset 720 of the bogie 700 is detected passing behind the corresponding bottom skirt brush 500, a second detection result is sent, for example, a digital output of a "0" level. The front wheelset 710 and the rear wheelset 720 can be distinguished by the first and second detection results, which can effectively determine the position of the bogie 700.

[0097] This embodiment provides a method for a car wash machine to avoid a train bogie 700. Compared with the avoidance method provided in Embodiment 5, the avoidance method provided in this embodiment only detects the position of the train bogie 700 in front of the corresponding under skirt brush 500, and step S200 is also different.
[0098] Specifically, in this embodiment, step S100 may include: sending a detection result when the wheelset of the train bogie 700 is first detected to pass; step S200 may include: based on the detection result, switching the state of the corresponding bottom skirt brush 500 from the open state to the closed state, then starting a timer, and when the timer reaches a preset duration, switching the state of the corresponding bottom skirt brush 500 from the closed state to the open state. In this way, the start and stop of the corresponding bottom skirt brush 500 can also be controlled to allow the corresponding bottom skirt brush 500 to avoid the train bogie 700.
