Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of braking devices, in particular to a temperature monitoring system for a braking device and a rail transit vehicle. BACKGROUND

[0002] A braking device is a core safety component in a rail transit vehicle. Its main function is to convert the kinetic energy of the vehicle into heat energy through friction when the vehicle needs to be decelerated or stopped, thereby achieving braking. During this process, the brake disc, as a key component of the braking device, plays an important role in converting kinetic energy into heat energy. An effective braking device can ensure the safe and reliable deceleration or stopping of the vehicle under various operating conditions, and is the basis for ensuring passenger safety and vehicle operation safety.

[0003] During the braking process of a rail transit vehicle, if the heat generated by the friction of the brake disc cannot be effectively dissipated, the temperature of the brake disc will continue to rise. High temperature not only affects the braking effect, but also accelerates the wear of the brake disc material, reduces its service life, and even causes braking failure in extreme cases, resulting in serious safety accidents. Therefore, how to effectively monitor and control the temperature of the brake disc to ensure its safe operation within a certain temperature range is an important technical challenge faced by the current braking system of a rail transit vehicle. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to provide a temperature monitoring system for a braking device, which can effectively solve the problem of temperature rise caused by the heat generated by the friction of the brake disc not being effectively dissipated, by monitoring the temperature of the brake disc in real time and automatically controlling the cooling device to dissipate heat, thereby improving the safety and reliability of the braking system of a rail transit vehicle. Another purpose of the present application is to provide a rail transit vehicle.

[0005] To achieve the above-mentioned purpose, the present application provides a temperature monitoring system for a braking device, comprising:

[0006] a brake disc;

[0007] a first sensor for monitoring the temperature of the brake disc in real time;

[0008] a control box connected to the first sensor signal, the control box being configured to receive the real-time monitoring temperature of the brake disc;

[0009] a cooling device connected to the control box signal, the cooling device being configured to dissipate heat from the brake disc under the control of the control box to reduce the real-time monitoring temperature of the brake disc.

[0010] In some embodiments, the control box is pre-set with a first threshold value;

[0011] When the control box receives the real-time monitoring temperature of the brake disc, if the real-time monitoring temperature of the brake disc meets the first threshold value, the control box controls the cooling device to start and perform heat dissipation on the brake disc.

[0012] In some embodiments, the control box is pre-set with a second threshold value.

[0013] When the control box receives the real-time monitoring temperature of the brake disc, if the real-time monitoring temperature of the brake disc does not meet the second threshold value, the control box controls the cooling device to be turned off.

[0014] The second threshold value is less than the first threshold value.

[0015] In some embodiments, the control box is further configured to control the cooling device to perform heat dissipation on the brake disc according to the braking level of the braking device.

[0016] In some embodiments, the control box and the first sensor are connected through wireless communication.

[0017] In some embodiments, the first sensor is arranged inside the brake disc.

[0018] In some embodiments, the first sensor is pre-embedded on one side of the braking surface of the brake disc; and / or,

[0019] The first sensor is a thermocouple.

[0020] In some embodiments, the number of the first sensors is multiple, and the multiple first sensors are uniformly distributed along the circumferential direction of the brake disc.

[0021] In some embodiments, the cooling device is provided with a blowing pipeline, which is used to blow cooling air flow to the brake disc to perform heat dissipation on the brake disc.

[0022] The application also provides a rail transit vehicle comprising the above-mentioned temperature monitoring system for a braking device.

[0023] With respect to the above background technology, the temperature monitoring system for a braking device provided by the application mainly comprises a brake disc, a first sensor, a control box and a cooling device. The first sensor is used to monitor the temperature of the brake disc in real time. The control box is signal connected with the first sensor, and is used to receive the real-time monitoring temperature of the brake disc. The cooling device is signal connected with the control box, and is used to perform heat dissipation on the brake disc under the control of the control box, so as to reduce the real-time monitoring temperature of the brake disc.

[0024] In rail transit vehicles, the safety of the braking device is crucial, especially during braking. If the heat generated by the friction of the brake disc cannot be effectively dissipated, the temperature of the brake disc will rise, affecting the braking effect, accelerating wear, and even causing brake failure. To solve this problem, the present application provides a temperature monitoring system that monitors the temperature of the brake disc in real time and automatically controls the cooling device to dissipate heat, effectively solving the problem of rising brake disc temperature.

[0025] The core components of the system include the brake disc, the first sensor, the control box, and the cooling device. The first sensor is responsible for real-time monitoring of the temperature of the brake disc. This real-time monitoring function ensures that the temperature data of the brake disc is obtained in real time, providing accurate data support for subsequent temperature control. The control box is signal connected with the first sensor and is used to receive the real-time monitoring temperature of the brake disc. As the center of the system, the control box can respond quickly according to the received temperature data. The cooling device is signal connected with the control box and implements heat dissipation on the brake disc under the instruction of the control box to reduce the temperature of the brake disc.

[0026] This design enables the system to respond to changes in the temperature of the brake disc in a timely manner, effectively dissipating heat from the brake disc through automatic control of the cooling device, thereby avoiding problems such as reduced braking performance and accelerated wear of brake disc materials caused by excessive temperature. In addition, this automatic heat dissipation mechanism reduces the need for human intervention, improves the response speed of the system and the convenience of operation, and thus improves the safety and reliability of the braking system of the rail transit vehicle as a whole. Therefore, the system not only solves the problem of rising brake disc temperature, but also provides a more solid guarantee for the safe operation of the rail transit vehicle.

[0027] In combination with the above structure and process description, it can be seen that the temperature monitoring system for the braking device has at least the following beneficial effects: the temperature monitoring system monitors the temperature of the brake disc in real time and automatically controls the cooling device to dissipate heat, effectively solving the problem of rising temperature caused by the heat generated by the friction of the brake disc, and improving the safety and reliability of the braking system of the rail transit vehicle.

[0032] The technical solutions in the embodiments of the present application will be apparently and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without any creative work fall within the protection scope of the present application.

[0033] In order for the person skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail in combination with the drawings and specific embodiments.

[0034] Reference is made to Figure 1 , Figure 1 The schematic diagram of the temperature monitoring system for the braking device provided by the embodiments of the present application.

[0035] In the first specific embodiment, the temperature monitoring system for the braking device provided by the embodiments of the present application mainly comprises a brake disc 1, a first sensor 2, a control box 3 and a cooling device 4. The first sensor 2 is used for monitoring the temperature of the brake disc 1 in real time. The control box 3 is in signal connection with the first sensor 2, and the control box 3 is used for receiving the real-time monitoring temperature of the brake disc 1. The cooling device 4 is in signal connection with the control box 3, and the cooling device 4 is used for cooling the brake disc 1 under the control of the control box 3, so as to reduce the real-time monitoring temperature of the brake disc 1.

[0036] In the rail transit vehicle, the safety of the braking device is crucial, especially during the braking process. If the heat generated by the friction of the brake disc 1 cannot be effectively dissipated, the temperature of the brake disc 1 will rise, which will affect the braking effect, accelerate the wear, and even cause the brake failure. In view of this problem, the present application provides a temperature monitoring system. The system can effectively solve the problem of temperature rise of the brake disc 1 by monitoring the temperature of the brake disc 1 in real time and automatically controlling the cooling device 4 to dissipate heat.

[0037] The core components of the system include the brake disc 1, the first sensor 2, the control box 3, and the cooling device 4. The first sensor 2 is responsible for real-time monitoring of the temperature of the brake disc 1, which ensures that the temperature data of the brake disc 1 is obtained in real time, providing accurate data support for subsequent temperature control. The control box 3 is signal connected with the first sensor 2, used to receive the real-time monitoring temperature of the brake disc 1, as the center of the system, the control box 3 can make a quick response according to the received temperature data. The cooling device 4 is signal connected with the control box 3, and under the instruction of the control box 3, it implements heat dissipation to the brake disc 1 to reduce the temperature of the brake disc 1.

[0038] This design enables the system to respond to changes in the temperature of the brake disc 1 in a timely manner, effectively dissipating heat from the brake disc 1 through automatic control of the cooling device 4, thereby avoiding problems such as reduced braking performance and accelerated wear of the brake disc 1 material due to excessive temperature. In addition, this automatic heat dissipation mechanism also reduces the need for human intervention, improving the response speed and convenience of operation of the system, thereby overall improving the safety and reliability of the braking system of the rail transit vehicle. Therefore, the system not only solves the problem of temperature rise of the brake disc 1, but also provides a more solid guarantee for the safe operation of the rail transit vehicle.

[0039] In combination with the above structure and process description, it can be seen that the temperature monitoring system for the braking device has at least the following beneficial effects: the temperature monitoring system effectively solves the problem of temperature rise of the brake disc 1 due to the heat generated by friction by real-time monitoring of the temperature of the brake disc 1 and automatically controlling the cooling device 4 to dissipate heat, thereby improving the safety and reliability of the braking system of the rail transit vehicle.

[0040] In some embodiments, the control box 3 is pre-set with a first threshold value;

[0041] When the control box 3 receives the real-time monitoring temperature of the brake disc 1, if the real-time monitoring temperature of the brake disc 1 meets the first threshold value, the control box 3 controls the cooling device 4 to start and dissipate heat to the brake disc 1.

[0042] In this embodiment, the control box 3 is set with a start temperature, i.e. the first threshold value. This first threshold value is a warning temperature point, which is set below the critical dangerous temperature that the brake disc 1 can withstand, ensuring that the brake disc 1 is properly cooled before reaching a temperature that may cause damage. Such a design allows the system to have enough time to respond to the temperature rise and take measures to prevent the temperature from further rising to a dangerous level.

[0043] The control box 3 receives real-time temperature monitoring data from the first sensor 2, which reflects the temperature changes of the brake disc 1 during operation. If the temperature of the brake disc 1 rises and reaches a first threshold preset by the control box 3, it means that the temperature of the brake disc 1 is approaching a level that may affect braking performance and safety. In this case, the control box 3 will automatically activate the cooling device 4 to dissipate heat from the brake disc 1.

[0044] By activating the cooling device 4 before the brake disc 1 reaches a dangerous temperature, the system effectively prevents the temperature of the brake disc 1 from continuing to rise, thereby avoiding problems such as decreased braking performance, brake disc 1 material fatigue, or damage. This preventative heat dissipation measure helps extend the service life of the brake disc 1 and ensures that the braking system of the rail transit vehicle is always kept in optimal operating condition.

[0045] Therefore, the temperature monitoring system in this embodiment improves the safety and reliability of the rail transit vehicle's braking system through intelligent temperature control and timely heat dissipation response, while also reducing the risk of braking system failure due to improper temperature control. This design not only improves the temperature management efficiency of the brake disc 1 but also provides strong protection for the safe operation of the rail transit vehicle.

[0046] In some embodiments, the control box 3 is preset with a second threshold;

[0047] When the control box 3 receives the real-time monitoring temperature of the brake disc 1, if the real-time monitoring temperature of the brake disc 1 does not meet the second threshold, the control box 3 controls the cooling device 4 to shut down.

[0048] The second threshold is less than the first threshold.

[0049] In this embodiment, the control box 3 not only presets a first threshold for activating the cooling device 4, but also additionally sets a second threshold, which is the temperature point at which the cooling device 4 is shut down. Compared to the first threshold, the second threshold is set to a lower temperature value, i.e., less than the first threshold. This design ensures that the cooling device 4 will not shut down when the temperature of the brake disc 1 is just below the activation temperature, but will stop working only when the temperature further decreases to a safer range.

[0050] When the first sensor 2 monitors the temperature of the brake disc 1 and transmits it to the control box 3, the control box 3 compares the real-time monitored temperature with the preset second threshold value. If the temperature of the brake disc 1 drops below the second threshold value, the control box 3 determines that the temperature at this time is low enough and does not need to continue to cool, so the control box 3 controls the cooling device 4 to be closed. This design allows the system to stop the cooling process when the temperature of the brake disc 1 drops to a safe margin, thereby avoiding frequent start and stop of the cooling device 4 due to temperature fluctuations, reducing energy waste and system loss.

[0051] By setting two different thresholds of start-up temperature (first threshold) and shutdown temperature (second threshold), the temperature monitoring system in this embodiment realizes intelligent control of the cooling device 4 within a certain temperature range. This control strategy not only improves the temperature management efficiency of the brake disc 1, but also helps to prolong the service life of the brake disc 1 and ensures that the braking system of the rail transit vehicle always remains in the best working state. At the same time, this design also reduces the risk of braking system failure caused by improper temperature control, enhancing the safety and reliability of the entire system.

[0052] In some embodiments, the control box 3 is also used to control the cooling of the brake disc 1 by the cooling device 4 according to the braking level implemented by the braking device.

[0053] In this embodiment, the function of the control box 3 is not limited to controlling the cooling device 4 according to the preset threshold, but is extended to adjusting the working state of the cooling device 4 according to different braking levels implemented by the braking device. The braking level reflects the heating condition of the brake disc 1 during braking, and different levels of braking correspond to different degrees of friction and heat generation.

[0054] The control box 3 can determine the heating state of the brake disc 1 by receiving the braking level information from the braking device. In light braking, the brake disc 1 generates less heat, and the control box 3 may reduce the running intensity of the cooling device 4 or delay its start to avoid excessive cooling and energy waste. Conversely, in high-intensity braking or emergency braking, the brake disc 1 generates a large amount of heat, and the control box 3 will start the cooling device 4 in time and may increase its running intensity to quickly and effectively reduce the temperature of the brake disc 1, preventing the decline of braking performance or safety risks caused by overheating.

[0055] This design of adjusting the working state of the cooling device 4 according to the braking level enables the temperature monitoring system to manage the temperature of the brake disc 1 more finely and intelligently. It not only improves the temperature control efficiency of the brake disc 1, but also optimizes energy use, prolongs the service life of the brake disc 1, and ensures the stability and reliability of the braking system under various braking conditions. Through this intelligent temperature management, the braking system of the rail transit vehicle can better adapt to different operating conditions, improving the safety performance of the whole vehicle.

[0056] In some cases, the temperature monitoring system for the braking device is particularly suitable for large-level braking of rail transit vehicles. In this case, when the rail transit vehicle performs large-level braking, the brake disc 1 will generate more heat than regular braking, and the role of the first sensor 2 becomes particularly important. The first sensor 2 is responsible for monitoring the temperature changes of the brake disc 1 in real time and transmitting these key data to the control box 3. The control box 3 evaluates the thermal state of the brake disc 1 according to the received temperature data and makes timely decisions. If the monitored temperature approaches or reaches the preset first threshold, indicating that the temperature of the brake disc 1 has risen to the point where cooling is needed, the control box 3 will immediately control the cooling device 4 to start and effectively cool the brake disc 1 to rapidly reduce its temperature, preventing a decrease in braking performance or damage to the brake disc 1 due to high temperature. This precise temperature control and timely cooling response ensures the safety and reliability of the braking system of the rail transit vehicle during large-level braking, while also protecting the brake disc 1 and prolonging its service life.

[0057] In some cases, for small-level braking of rail transit vehicles, the temperature monitoring system for the braking device can temporarily stop working. This is because during small-level braking, the brake disc 1 generates relatively little heat, which is not enough to cause a significant temperature rise, so additional cooling measures are not needed. In this case, the system is designed to allow the control box 3 to decide whether to start the cooling device 4 according to the braking level and the actual temperature of the brake disc 1. If the temperature monitored by the first sensor 2 is far below the starting threshold, indicating that the temperature of the brake disc 1 is within a safe range, the control box 3 can keep the cooling device 4 in an off state to save energy and reduce unnecessary system wear. Such a design makes the temperature monitoring system more flexible and efficient, allowing it to intelligently adjust its working mode according to different braking needs and heat generation conditions, ensuring that necessary cooling is provided when needed and the system remains at rest when not needed, thus achieving optimal management of the braking system of the rail transit vehicle.

[0058] It should be noted that the present embodiment does not limit the working principle of the first sensor 2. This means that no matter whether the first sensor 2 is based on thermocouple, thermistor, infrared sensing technology, or any other sensor technology capable of accurately monitoring the temperature of the brake disc 1, as long as it can monitor the temperature of the brake disc 1 in real time and transmit data to the control box 3, these different working principles and sensor types should be considered within the scope of the present embodiment.

[0059] In some embodiments, the first sensor 2 is a thermocouple.

[0060] In the present embodiment, the first sensor 2 uses a thermocouple as a temperature monitoring element. Due to its high precision and fast response time, the thermocouple is very suitable for real-time monitoring of the temperature changes of the brake disc 1. As a temperature sensor, the thermocouple can convert temperature changes into electrical signals, which are then transmitted to the control box 3 for analysis and processing.

[0061] When the brake disc 1 generates heat during braking, the thermocouple can quickly detect this change and generate corresponding electrical signals. After receiving these signals, the control box 3 will determine the current temperature of the brake disc 1 according to the strength of the signals. If the temperature reading shows that the temperature of the brake disc 1 is close to or exceeds the first preset threshold, the control box 3 will start the cooling device 4 to dissipate heat, so as to keep the temperature of the brake disc 1 within a safe working range. Conversely, if the temperature reading is far below the second threshold, indicating that the temperature of the brake disc 1 is low enough, the control box 3 will turn off the cooling device 4 to avoid unnecessary energy consumption and system activation.

[0062] It should be noted that the present embodiment does not limit the specific installation position of the first sensor 2. The first sensor 2 can be directly installed on the brake disc 1 to more accurately monitor the temperature changes of the brake disc, or it can be separated from the brake disc 1, such as being installed on the body of the rail transit vehicle or other positions that are convenient for monitoring and installation. These different installation methods should be considered within the scope of the present embodiment.

[0063] In some embodiments, the first sensor 2 is installed inside the brake disc 1.

[0064] In the present embodiment, the first sensor 2 is directly installed inside the brake disc 1. This design allows the first sensor 2 to more accurately monitor the temperature of the brake disc 1, as it is directly exposed to the heat generated by the brake disc 1. The internal installation position allows the first sensor 2 to immediately sense small changes in temperature during braking, thereby providing the most direct and accurate temperature data.

[0065] Since the first sensor 2 is located inside the brake disc 1, it can quickly respond to temperature increases, which is crucial for reacting rapidly during braking. When the brake disc 1 generates heat due to friction, the internal thermocouple (first sensor 2) can immediately detect this change and quickly transmit the data to the control box 3. Based on these data, the control box 3 can determine in time whether to activate the cooling device 4 for heat dissipation, to keep the temperature of the brake disc 1 within a safe working range.

[0066] This internal installation method also helps to reduce the influence of environmental factors on temperature readings, as the first sensor 2 is protected by the brake disc 1 itself and is less susceptible to external environmental temperature changes. This enhances the reliability and stability of the system, ensuring accurate temperature monitoring even under extreme conditions, thereby improving the safety and efficiency of the rail transit vehicle braking system.

[0067] In some embodiments, the first sensor 2 is pre-embedded on the braking surface side of the brake disc 1.

[0068] In this embodiment, the first sensor 2 is specifically designed to be pre-embedded on the braking surface side of the brake disc 1. This installation method allows the sensor to be very close to the area where heat is generated during braking, thus most directly sensing the heat changes generated by the brake disc 1 due to friction.

[0069] Since the first sensor 2 is directly embedded in the braking surface of the brake disc 1, it can quickly respond to small changes in temperature and quickly transmit data to the control box 3. This layout not only improves the response speed and accuracy of temperature monitoring, as it reduces the path length of heat transfer from the brake disc 1 to the sensor, but also helps to protect the first sensor 2 from direct environmental influences such as rain, mud or other contaminants that may affect the performance of the sensor.

[0070] Such an embedded design enhances the durability of the sensor, ensuring long-term reliability and reducing maintenance requirements. Therefore, this pre-embedded first sensor 2 design not only improves the accuracy and response speed of temperature monitoring, but also enhances the durability and maintainability of the sensor, which is crucial for ensuring the safe and effective operation of the rail transit vehicle braking system under various conditions.

[0071] It should be noted that the present embodiment does not limit the communication principle between the control box 3 and the first sensor 2. This means that the communication between the control box 3 and the first sensor 2 can adopt various communication modes such as wired or wireless. Whether it is direct data transmission through wired connection such as cable or optical fiber, or remote data transmission through wireless technologies such as Bluetooth, Wi-Fi, ZigBee, cellular network, as long as they can ensure that the temperature data of the brake disc 1 monitored by the first sensor 2 is accurately transmitted to the control box 3 and processed and instructed by the control box 3, these different communication modes should be considered within the scope of the present embodiment.

[0072] In some embodiments, the control box 3 and the first sensor 2 are connected by wireless communication.

[0073] In the present embodiment, the wireless communication mode provides flexibility in installation and layout, so that the first sensor 2 can be pre-buried on the brake surface side of the brake disc 1 without worrying about the complexity of wiring. By using wireless technologies such as Bluetooth, infrared, etc., the system can reduce signal interference and physical damage that may be caused by cable connection, enhancing the stability and reliability of the system.

[0074] Using wireless communication technology, the first sensor 2 can transmit the monitored temperature data of the brake disc 1 to the control box 3 in real time without relying on physical connection. This way makes the system installation more convenient, while also reducing maintenance costs and potential failure points. After receiving these data, the control box 3 can determine whether to start the cooling device 4 to dissipate heat according to the real-time temperature reading, so as to keep the temperature of the brake disc 1 within a safe working range.

[0075] In addition, the application of wireless communication technology also improves the flexibility and scalability of the system, facilitating future upgrades and functional expansion. For example, the system can easily add more sensors or integrate with other vehicle systems to achieve more comprehensive vehicle monitoring and management. Therefore, this wireless connection method not only improves the practicality and flexibility of the temperature monitoring system, but also provides technical support for the intelligentization and automation of rail transit vehicles.

[0076] In some embodiments, the number of first sensors 2 is multiple, and the multiple first sensors 2 are uniformly distributed along the circumferential direction of the brake disc 1.

[0077] In the present embodiment, in order to improve the comprehensiveness and accuracy of temperature monitoring, multiple first sensors 2 are uniformly distributed along the circumferential direction of the brake disc 1. This design allows the system to monitor the temperature of the brake disc 1 from multiple positions, thereby obtaining more comprehensive thermal distribution data. By deploying multiple sensors in different areas of the brake disc 1, local hot spots or temperature anomalies can be detected more accurately, which may be difficult to capture by a single sensor.

[0078] This uniform distribution of sensors helps to ensure that the temperature of the brake disc 1 is effectively monitored under any braking condition. When the brake disc 1 generates heat due to friction, each first sensor 2 can independently monitor the temperature change of its respective area and transmit the data to the control box 3. The control box 3 can integrate these data to more accurately assess the overall thermal state of the brake disc 1, thereby more effectively controlling the activation and deactivation of the cooling device 4.

[0079] The use of multiple first sensors 2 also increases the redundancy of the system, so that even if a sensor fails, other sensors can still provide sufficient data to maintain the continuity of temperature monitoring. This design improves the reliability of the system, ensuring that temperature monitoring and control of the brake disc 1 can still be carried out normally even in the event of partial sensor failure.

[0080] It should be noted that the present embodiment does not limit the working principle of the cooling device 4. This means that the cooling device 4 can adopt various cooling technologies such as air cooling or water cooling to adapt to different application requirements and environmental conditions. Whether it is an air cooling system that blows cold air to reduce the temperature of the brake disc 1, or a water cooling system that circulates cooling liquid to absorb and carry away heat, as long as it can effectively cool the brake disc 1 under the control of the control box 3 to reduce the real-time monitoring temperature of the brake disc 1, these different cooling principles and methods should be considered within the scope of the present embodiment.

[0081] In some embodiments, the cooling device 4 is provided with a blowing pipeline for blowing cooling air flow to the brake disc 1 to cool it.

[0082] In the present embodiment, the cooling device 4 is specially designed to effectively cool the brake disc 1. The cooling device 4 includes a blowing pipeline that faces the brake disc 1 for blowing cooling air flow to reduce its temperature. The cooling device 4 can be fixed on the vehicle body of the rail transit vehicle, usually at the lower part of the vehicle body, which is beneficial for directly cooling the brake disc 1 while reducing interference with other parts of the vehicle.

[0083] In addition to the blowing pipeline, the cooling device 4 also includes a fan that is responsible for generating sufficient wind power to blow cold air directly to the brake disc 1 through the blowing pipeline to achieve rapid cooling. This direct cooling method can quickly reduce the temperature of the brake disc 1, which is particularly important when the temperature of the brake disc 1 rises rapidly after high-intensity braking or continuous braking.

[0084] In some necessary cases, the cooling device 4 can further include a heat sink to enhance the cooling effect. The heat sink can be a heat exchanger that absorbs and dissipates heat through the circulation of the vehicle's cooling liquid, further improving the cooling efficiency. This design that combines the use of fans and heat sinks provides a powerful cooling solution, ensuring that the brake disc 1 remains within a safe temperature range under various braking loads.

[0085] The present application also provides a rail transit vehicle comprising the above-mentioned temperature monitoring system for brake devices.

[0086] The rail transit vehicle should have all the beneficial technical effects of the above-mentioned temperature monitoring system for brake devices, which will not be repeated here.

[0087] In some embodiments, the design of the rail transit vehicle includes setting up a control box 3 on each car body. Such a layout aims to achieve localized control of temperature monitoring and management of the brake disc 1 on each car body. Each control box 3 is responsible for collecting and determining whether the temperature of the brake disc 1 on the corresponding car body meets the preset safety requirements.

[0088] This design makes the temperature monitoring system have a distributed architecture, and each control box 3 can independently process data from the first sensor 2 on its corresponding car body. When the temperature data monitored by the first sensor 2 is transmitted to the corresponding control box 3, the control box 3 will determine whether the temperature condition of the brake disc 1 is normal according to these data and the preset threshold value. If the temperature exceeds the first preset threshold value, the control box 3 will start the cooling device 4 to reduce the temperature of the brake disc 1; if the temperature is lower than the second threshold value, the control box 3 will turn off the cooling device 4 to avoid unnecessary energy consumption.

[0089] This practice of setting up a control box 3 on each car body improves the flexibility and efficiency of temperature monitoring and response of the entire rail transit vehicle. It allows for customized temperature management of the braking system of each car body, taking into account the different heat generated by different car bodies due to different loads, usage frequency and other operating conditions. In addition, this also simplifies the maintenance and fault diagnosis process of the system, because each control box 3 can independently monitor and control the brake disc temperature of its corresponding car body, making problem positioning and solving more rapid and accurate.

[0090] It should be noted that many components mentioned in this application are general standard components or components known to those skilled in the art, the structure and principle of which can be known by the technical personnel through technical manual or through conventional experimental method.

[0091] It should be noted that the relational terms herein, such as first and second, are used solely to distinguish one from another entity without necessarily requiring or implying any actual relationship or order between such entities.
