[0047] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0048] In the event that a train idles or slides due to rain or snow, the train operator will report the idling and sliding to the train dispatcher. After confirmation by the train dispatcher, a temporary speed limit is set to reduce the idling and sliding conditions so that the train can run according to the set temporary speed limit to ensure driving safety. When the weather is fine, the train dispatcher manually determines and cancels the temporary speed limit, and the ATS system switches the online train operation to normal mode. After each online train is set to normal mode by the ATS system, it controls the train operation according to the normal mode operating parameters. However, setting a temporary speed limit based on human judgment may sometimes lead to misjudgment or delay.

[0049] In view of the above situation, the present invention provides a method for temporarily limiting the speed of urban rail when a train is running. Figure 1 FIG. 1 is a flow chart of a method for temporarily limiting the speed of urban rails during train operation according to an exemplary embodiment. Figure 1 As shown, the temporary speed limit method for urban rail when the train is running includes:

[0050] Based on parameter sensors deployed on the track in the train running area, at least two of the humidity, temperature and pressure of the track in the running area are collected to obtain at least two of the current humidity, current temperature and current pressure of the track in the running area;

[0051] Determine a current state value of the track in the operating area based on at least two of the current humidity, current temperature and current pressure of the track in the operating area; wherein the current state value is used to characterize a safety state of a train when it runs on the track in the operating area at a predetermined speed;

[0052] Based on the current state value of the track in the operating area, the current speed of the train when running on the track in the operating area is adjusted.

[0053] In this exemplary embodiment, the central ATS system detects temperature and humidity through the sensor device deployed on the track and uploads them to the central ATS system, which then summarizes the data. It then determines whether a temporary speed limit needs to be set based on the set parameters to solve the problem that the train dispatcher fails to set a temporary speed limit in time based on the driving information fed back by the driver, resulting in a long braking distance for the train and a poor passenger experience.

[0054] This application implements dynamic setting of temporary speed limits in different areas, based on different area divisions, such as ground, elevated, field / section, transition section between ground and underground, and open-air lines, and then dynamically sets temporary speed limits based on different configuration parameters. The central ATS system summarizes and calculates the data collected from different areas, and then determines whether it is necessary to dynamically set a temporary speed limit based on the parameters configured for different areas. If the central ATS calculates based on the collected data and does not meet the requirements for dynamically setting the temporary speed limit, the temporary speed limit in this area will be dynamically canceled, and the train will run at the automatic operating speed.

[0055] In some embodiments, different operating areas have different state limit values;

[0056] The adjusting the current speed of the train when running on the track in the operating area based on the current state value of the track in the operating area includes:

[0057] Comparing the current state value of the track in the operating area with the state limit value corresponding to the operating area to obtain a comparison result;

[0058] Based on the comparison result, the current speed of the train when running on the track in the operating area is adjusted.

[0059] In this exemplary embodiment, adjusting the current speed of the train when running on the track in the operation area based on the comparison result includes:

[0060] If the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, the current speed of the train when running on the track in the operating area is reduced so that the train runs on the track in the operating area at a safe speed;

[0061] If the comparison result is that the current state value of the track in the operating area is less than or equal to the state limit value corresponding to the operating area, the current speed of the train when running on the track in the operating area is maintained.

[0062] In this exemplary embodiment, if the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, it means that the humidity and temperature of the track in the operating area are relatively high at this time, and the train may be idling and slipping at the current speed. In this regard, it is necessary to reduce the current speed of the train when it is running on the track in the operating area, so that the train can run on the track in the operating area at a safe speed.

[0063] If the comparison result is that the current state value of the track in the operating area is less than or equal to the state limit value corresponding to the operating area, it means that the humidity and temperature of the track in the operating area are relatively small at this time, and within a reasonable range, there is no risk of idling or slipping when the train runs. At this time, the current speed of the train when running on the track in the operating area can be maintained.

[0064] In some embodiments, adjusting the current speed of the train when running on the track in the operation area based on the comparison result includes:

[0065] If the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, determining whether there is a temporary speed limit on the track in the operating area;

[0066] If there is a temporary speed limit on the track in the operating area, reducing the current speed of the train to a speed range within the temporary speed limit;

[0067] If there is no temporary speed limit on the track in the operation area, setting a temporary speed limit for the train when it is running on the track in the operation area;

[0068] If the comparison result is that the current state value of the track in the operating area is less than or equal to the state limit value corresponding to the operating area, determining whether there is a temporary speed limit on the track in the operating area;

[0069] If there is a temporary speed limit on the track in the operating area, the temporary speed limit on the track in the operating area is canceled to maintain the current speed of the train when running on the track in the operating area.

[0070] In this exemplary embodiment, if the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, it means that the temperature and humidity of the track in the operating area are relatively high, and it is necessary to determine whether there is a temporary speed limit on the track in the operating area. If there is a temporary speed limit on the track in the operating area, the current speed of the train is reduced to within the speed range of the temporary speed limit according to the temporary speed limit to ensure the safe operation of the train. If there is no temporary speed limit on the track in the operating area, a temporary speed limit is set when the train is running on the track in the operating area to reduce the current speed of the train to within the speed range of the temporary speed limit to ensure the safe operation of the train.

[0071] If the comparison result is that the current state value of the track in the operating area is less than or equal to the state limit value corresponding to the operating area, determining whether there is a temporary speed limit on the track in the operating area;

[0072] If there is a temporary speed limit on the track in the operating area, the temporary speed limit on the track in the operating area is canceled to maintain the current speed of the train when running on the track in the operating area.

[0073] In this exemplary embodiment, the calculation method for dynamically setting the temporary speed limit is determined by using the data collected by the sensor to ensure the safety of train operation. Through the data collected by the sensor, the central server makes a judgment based on the set parameters and enters the dynamic setting of the temporary speed limit to ensure the safety of train operation. The stable operation of the train plays a key role in the service quality and operation level of urban rail transit.

[0074] In some embodiments, determining the current state value of the track in the operating area based on at least two of current humidity, current temperature, and current pressure of the track in the operating area includes:

[0075] Based on at least two of the current humidity, current temperature and current pressure of the track in the operating area, and weights corresponding to at least two of the current humidity, current temperature and current pressure, a current state value of the track in the operating area is determined.

[0076] In some embodiments, the current humidity corresponds to a first weight, the current temperature corresponds to a second weight, and the current pressure corresponds to a third weight;

[0077] The determining of the current state value of the track in the operating area based on at least two of the current humidity, the current temperature and the current pressure of the track in the operating area, and weights corresponding to at least two of the current humidity, the current temperature and the current pressure, includes:

[0078] According to the current state of the train operation and the necessity of influencing factors when considering the current state value, the first weight corresponding to the current humidity, the second weight corresponding to the current temperature, and the third weight corresponding to the current pressure are adjusted.

[0079] In this exemplary embodiment, when determining the current state value of the track in the operating area, the weights corresponding to each factor are different due to the different factors affecting the current state value of the track in the operating area. Therefore, when specifically determining the current state value of the track in the operating area, the current state of the train operation and the necessity of the influencing factors when considering the current state value can be adjusted. For example, when considering two or three of the current humidity, current temperature and current pressure of the track in the operating area, the corresponding weights can be adjusted. For example, considering the current humidity and current temperature of the track in the operating area, or, considering the current temperature and current pressure of the track in the operating area, or, considering the current humidity and current pressure of the track in the operating area, the corresponding weight values ​​can be adjusted when selecting. At the same time, when considering the same influencing factors, the weights corresponding to each factor can also be adjusted according to the current operating state of the train. For example, if the current operating state of the train is very good, the proportion of the party with a larger corresponding value of the influencing factor can be appropriately reduced; if the current operating state of the train is not very good, the proportion of the party with a larger corresponding value of the influencing factor can be appropriately increased.

[0080] In this exemplary embodiment, determining the current state value of the track in the operating area based on the current humidity and the current temperature of the track in the operating area includes:

[0081] Based on the current humidity of the track in the operating area, the first weight corresponding to the current humidity, the current temperature of the track in the operating area, and the second weight corresponding to the current temperature, the current state value of the track in the operating area is determined. Wherein, the first weight and the second weight can be set as needed. For example, the first weight is 40%, the second weight is 60%, or the first weight is 50%, the second weight is 50%, and so on. Wherein, the current state value L = the current humidity S of the track in the operating area * the first weight W1 + the current temperature P of the track in the operating area * the second weight W2; wherein the first weight W1 + the second weight W2 = 100%. In this application, when determining the current state value of the track in the operating area, the current humidity of the track in the operating area and the current temperature of the track in the operating area can be adjusted according to the specific operating state of the train by using the first weight corresponding to the current humidity and the second weight corresponding to the current temperature. The weight ratio is adjusted, so that a more reasonable current state value can be determined according to the operating state of the train, thereby providing a judgment basis for the effective speed limit of the train.

[0082] Figure 2 FIG. 1 is a data collection flow chart of a method for temporarily limiting the speed of urban rails during train operation according to an exemplary embodiment. Figure 2 As shown in the figure, the data collection process includes:

[0083] Step 20, start;

[0085] Step 22: Transmit the collected temperature and humidity to the regional controller;

[0086] Step 23: Transmit the collected temperature and humidity to the central service processor;

[0087] Step 24, end.

[0088] Figure 3 FIG. 1 is a flow chart of a process for determining a dynamic temporary speed limit according to an exemplary embodiment. Figure 3 As shown, the dynamic temporary speed limit determination process is entered, including:

[0089] Step 30, start;

[0090] Step 31, the central service processor generates temperature and humidity detection instructions;

[0091] Step 32, periodically calculating humidity and temperature according to temperature and humidity detection instructions;

[0092] Step 33: Based on the temperature and humidity, determine whether the current state value of the track in the operating area meets the set parameters;

[0093] Step 34: If the current state value of the track in the operating area meets the set parameters, determine whether there is a temporary speed limit;

[0094] Step 35: If there is no temporary speed limit, dynamically set the temporary speed limit;

[0095] Step 36: If there is a temporary speed limit, the determination ends;

[0096] Step 37: If the current state value of the track in the operating area does not meet the set parameters, determine whether there is a temporary speed limit;

[0097] Step 38: If there is a temporary speed limit, dynamically cancel the temporary speed limit.

[0098] The present invention discloses a temporary speed limiting device for urban rails when a train is running. Figure 4 FIG. 1 is a schematic diagram of the structure of a temporary speed limiting device for urban rails during train operation according to an exemplary embodiment. Figure 4 As shown in the figure, the temporary speed limiting device for urban rails when the train is running includes:

[0099] The data acquisition module 40 is used to collect at least two of the humidity, temperature and pressure of the track in the running area based on parameter sensors deployed on the track in the train running area, and obtain at least two of the current humidity, current temperature and current pressure of the track in the running area;

[0100] A state value determination module 41 is used to determine a current state value of the track in the operating area based on at least two of the current humidity, current temperature and current pressure of the track in the operating area; wherein the current state value is used to represent a safety state of a train when it runs on the track in the operating area at a predetermined speed;

[0101] The speed adjustment module 42 is used to adjust the current speed of the train when it is running on the track in the operating area based on the current state value of the track in the operating area.

[0102] In this exemplary embodiment, the central ATS system detects temperature and humidity through the sensor device deployed on the track and uploads them to the central ATS system, which then summarizes the data. It then determines whether a temporary speed limit needs to be set based on the set parameters to solve the problem that the train dispatcher fails to set a temporary speed limit in time based on the driving information fed back by the driver, resulting in a long braking distance for the train and a poor passenger experience.

[0103] This application implements dynamic setting of temporary speed limits in different areas, based on different area divisions, such as ground, elevated, field / section, transition section between ground and underground, and open-air lines, and then dynamically sets temporary speed limits based on different configuration parameters. The central ATS system summarizes and calculates the data collected from different areas, and then determines whether it is necessary to dynamically set a temporary speed limit based on the parameters configured for different areas. If the central ATS calculates based on the collected data and does not meet the requirements for dynamically setting the temporary speed limit, the temporary speed limit in this area will be dynamically canceled, and the train will run at the automatic operating speed.

[0104] In some embodiments, different operating areas have different state limit values;

[0105] The speed adjustment module is used to

[0106] Comparing the current state value of the track in the operating area with the state limit value corresponding to the operating area to obtain a comparison result;

[0107] Based on the comparison result, the current speed of the train when running on the track in the operating area is adjusted.

[0108] In this exemplary embodiment, the speed adjustment module is used to

[0109] If the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, the current speed of the train when running on the track in the operating area is reduced so that the train runs on the track in the operating area at a safe speed;

[0110] If the comparison result is that the current state value of the track in the operating area is less than or equal to the state limit value corresponding to the operating area, the current speed of the train when running on the track in the operating area is maintained.

[0111] In this exemplary embodiment, if the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, it means that the humidity and temperature of the track in the operating area are relatively high at this time, and the train may be idling and slipping at the current speed. In this regard, it is necessary to reduce the current speed of the train when it is running on the track in the operating area, so that the train can run on the track in the operating area at a safe speed.

[0112] If the comparison result is that the current state value of the track in the operating area is less than or equal to the state limit value corresponding to the operating area, it means that the humidity and temperature of the track in the operating area are relatively small at this time, and within a reasonable range, there is no risk of idling or slipping when the train runs. At this time, the current speed of the train when running on the track in the operating area can be maintained.

[0113] In some embodiments, the speed adjustment module is used to

[0114] If the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, determining whether there is a temporary speed limit on the track in the operating area;

[0115] If there is a temporary speed limit on the track in the operating area, reducing the current speed of the train to a speed range within the temporary speed limit;

[0116] If there is no temporary speed limit on the track in the operation area, setting a temporary speed limit for the train when it is running on the track in the operation area;

[0118] If there is a temporary speed limit on the track in the operating area, the temporary speed limit on the track in the operating area is canceled to maintain the current speed of the train when running on the track in the operating area.

[0119] In this exemplary embodiment, if the comparison result is that the current state value of the track in the operating area is greater than the state limit value corresponding to the operating area, it means that the temperature and humidity of the track in the operating area are relatively high, and it is necessary to determine whether there is a temporary speed limit on the track in the operating area. If there is a temporary speed limit on the track in the operating area, the current speed of the train is reduced to within the speed range of the temporary speed limit according to the temporary speed limit to ensure the safe operation of the train. If there is no temporary speed limit on the track in the operating area, a temporary speed limit is set when the train is running on the track in the operating area to reduce the current speed of the train to within the speed range of the temporary speed limit to ensure the safe operation of the train.

[0121] If there is a temporary speed limit on the track in the operating area, the temporary speed limit on the track in the operating area is canceled to maintain the current speed of the train when running on the track in the operating area.

[0122] In this exemplary embodiment, the calculation method for dynamically setting the temporary speed limit is determined by using the data collected by the sensor to ensure the safety of train operation. Through the data collected by the sensor, the central server makes a judgment based on the set parameters and enters the dynamic setting of the temporary speed limit to ensure the safety of train operation. The stable operation of the train plays a key role in the service quality and operation level of urban rail transit.
