Description

Technical Field

[0001] The present invention relates to the technical field of train control, and particularly to an intelligent control system for sightseeing trains. Background Art

[0002] A sightseeing train is a short-distance transportation vehicle specially designed for tourism sightseeing, usually consisting of a small locomotive towing multiple passenger cars. Sightseeing trains are usually used in tourist attractions, coastal resorts or historical and cultural famous cities, providing convenient transportation services for tourists and bringing a better sightseeing experience through the scenery outside the window. Sightseeing trains have been widely used abroad and there is a large market demand in China.

[0003] Since sightseeing trains usually require the construction of specific tracks or lines, and the terrain inside the scenic area is complex, there is a situation of skidding during the driving on slopes and curves. Therefore, it is difficult to construct tracks in existing scenic areas. Through the speed measurement of the installed sightseeing trains, it is found that usually the flat slope speed of the train can meet the requirements of the designed speed, but there is an obvious stutter when the sightseeing train goes uphill, and the speed decreases significantly after going uphill.

[0004] Therefore, there is a need for an intelligent control system for sightseeing trains that can effectively maintain the designed speed during the train operation. Summary of the Invention

[0005] The present invention provides an intelligent control system for sightseeing trains, which can effectively maintain the designed speed during the train operation.

[0006] To solve the above technical problems, the present application provides the following technical solutions:

[0007] The intelligent control system for sightseeing trains includes: a sensor module, a central control module, a power module and a control execution module;

[0008] The sensor module is used to collect the state data during the train operation, and the state data includes the running speed, the train inclination angle and the number of passengers;

[0009] The central control module is used to obtain the running speed, judge whether the running speed reaches the preset running speed, and if it does not reach the preset running speed, generate a speed regulation instruction;

[0010] The central control module is also used to obtain the train inclination angle, judge whether the inclination angle is greater than the preset inclination angle value, and if it is greater than the preset inclination angle value, judge that it enters a slope; after entering the slope, generate a sand spreading start instruction, and after ending the slope, generate a sand spreading end instruction;

[0011] The power module includes a drive motor and a drive wheel sand spreading device;

[0012] The control execution module includes a driving execution unit and an anti-skid execution unit;

[0013] The driving execution unit is used to adjust the rotational speed of the driving motor according to the speed regulation instruction; the anti-skid execution unit is used to control the driving wheel sanding device to perform sanding operation according to the sanding start instruction, and control the driving wheel sanding device to end the sanding operation according to the sanding end instruction.

[0014] Furthermore, the state data further includes the number of passengers;

[0015] The central control module is also used to obtain the number of passengers, judge whether the number of passengers exceeds the preset number of passengers, and generate an overload alarm if it exceeds the preset number of passengers.

[0016] Furthermore, the state data further includes the position;

[0017] The central control module is also used to draw the running track according to the running position, identify the curve according to the running track, judge whether the turning radius is greater than the threshold, and generate a turning radius warning message if it is greater than the threshold.

[0018] Furthermore, it further includes a display module, which is used to display the current running speed, position and the number of passengers, and is also used to display the overload alarm and the turning radius warning message.

[0019] Furthermore, the sensor module includes:

[0020] A speed sensor, which is used to monitor the rotational speed of the train and calculate the running speed; in this embodiment, a Hall effect sensor is adopted;

[0021] A GPS module, which is used to provide geographical location data to obtain the current position;

[0022] An inclination sensor, which is used to monitor the inclination of the train;

[0024] Furthermore, the sensor module further includes a rain sensor, and the central control module is also used to obtain rain data from the rain sensor for real-time analysis to identify whether it is raining currently and the specific rainfall;

[0025] The central control module is also used to judge whether the rainfall exceeds the rainfall threshold when it is raining, and reduce the preset running speed if it exceeds the rainfall threshold.

[0026] This solution collects the running speed of the train in real time through the sensor module. The central control module can accurately judge whether the train reaches the preset running speed and timely adjusts the rotation speed of the drive motor through the drive execution unit. When it identifies that the train enters a ramp, it performs a sand spraying operation through the control of the drive wheel sand spraying device to increase the friction between the wheels and the track, effectively preventing the train from slipping on the ramp, so as to ensure that the train can stably maintain the designed speed during operation, especially in complex terrains such as ramps.

[0029] The following is a more detailed description through specific embodiments:

[0030] First Embodiment

[0031] As Figure 1 shown, the intelligent control system for the sightseeing train in this embodiment includes: a sensor module, a central control module, a power module, a control execution module, and a display module.

[0032] The sensor module is used to collect the status data during the running of the train, and the status data includes running speed, position, train inclination angle, number of passengers, etc.

[0033] Specifically, the rotation speed of the train is monitored by a speed sensor installed on the wheel or shaft and the running speed is calculated; in this embodiment, a Hall effect sensor is used;

[0034] The GPS module installed on the train roof provides accurate geographical location data, so as to obtain the current position;

[0035] The inclination angle of the train is monitored by an inclination sensor installed at the bottom of the train;

[0036] The infrared sensor installed at the entrance of the carriage counts the number of people getting on and off and the number of passengers in the carriage.

[0037] The central control module is used to perform real-time analysis on the status data collected by the sensor, judge the running state of the train and generate corresponding control instructions.

[0038] Specifically, the central control module is used to obtain the running speed, determine whether the running speed reaches the preset running speed, and generate a speed regulation instruction if it does not reach the preset running speed. In this embodiment, the PID control algorithm is adopted to adjust the power of the train in real time according to the error between the running speed and the preset running speed, so as to suppress the speed fluctuation and achieve stable operation.

[0039] The central control module is also used to obtain the number of passengers, determine whether the number of passengers exceeds the preset number of passengers, and generate an overloading alarm if it does.

[0040] The central control module is also used to obtain the train inclination angle, determine whether the inclination angle is greater than the preset inclination angle value, and determine that it enters a ramp if it is greater than the preset inclination angle value. After entering the ramp, a sand spreading start instruction is generated, and after the ramp ends, a sand spreading end instruction is generated.

[0041] The central control module is also used to draw the running track according to the running position, identify the curve according to the running track, and determine whether the turning radius is greater than the threshold value. If it is greater than the threshold value, a turning radius warning message is generated.

[0042] The power module includes a drive motor and a drive wheel sand spreading device.

[0043] The control execution module includes a drive execution unit and an anti-skid execution unit;

[0044] The drive execution unit is used to adjust the speed of the drive motor according to the speed regulation instruction. Specifically, the speed of the drive motor is adjusted by a frequency converter, so as to accurately control the speed of the train.

[0045] The anti-skid execution unit is used to control the drive wheel sand spreading device to perform sand spreading operations according to the sand spreading start instruction and end the sand spreading operations according to the sand spreading end instruction.

[0046] The display module is used to display the current running speed, position and number of passengers, and is also used to display the overloading alarm and the turning radius warning message. The display module can provide an information display and operation platform for the staff and support the real-time monitoring of the train running state.

[0047] By conducting on-site inspections and statistics on the current situations affecting the uphill efficiency of the sightseeing train, it is found that the problems affecting the uphill efficiency of the sightseeing train with large curvature include overloading, insufficient running speed, insufficient rail friction, insufficient starting speed, and non-smoothness at the rail joints. By counting the quality defect frequencies of each problem, it is determined that insufficient running speed and insufficient rail friction are the main problems. After investigation, the end factors of the main problems are as Figure 2As shown in the figure, through the investigation and analysis of the end factors, it is found that the insufficient power of the sightseeing train has little impact on "insufficient running speed" and "insufficient rail friction"; the average slip amount under full load is 2.01 times that under no load, so it is proved that different vehicle loads have a greater impact on "insufficient rail friction"; there is basically no difference in the uphill time of the sightseeing train in different weather conditions, and the wetness of the track and wheel surfaces has little impact on "insufficient rail friction"; there is basically no difference in the average speed of the sightseeing train on different uphill lengths; there is a large difference in the average speed of the sightseeing train on different turning radii, which has an obvious impact on the overall uphill speed; the unevenness of the track line has a small impact on "insufficient running speed" and is a non-key factor; there is a very small difference in the average speed of the sightseeing train in different weather conditions, and the impact of the surrounding environment on the overall uphill speed is not obvious; finally, it is confirmed that the following two end factors are the main factors: too small turning radius and different vehicle loads.

[0048] To solve the above problems, the solution of this embodiment can effectively reduce the load through overload alarm. When going uphill, sand is automatically scattered for anti-slip treatment on the slope to increase the rail friction, thereby solving the vehicle load problem. In the case where there are problems with the design of the track turning radius during the preliminary construction, it is also possible to identify the situation where the track radius is too small, which is convenient for subsequent adjustment of the track radius.

[0049] In summary, this solution can enable the sightseeing train to effectively maintain the designed speed during operation.

[0050] Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that in this embodiment, the sensor module further includes a rain sensor, and the central control module is further configured to obtain rain data from the rain sensor for real-time analysis to identify whether it is raining currently and the specific rainfall amount;

[0052] The central control module is further configured to, when it is raining, determine whether the rainfall amount exceeds the rainfall threshold. If it exceeds the rainfall threshold, the preset running speed is reduced to ensure the running safety of the sightseeing train.

[0053] The central control module is further configured to, when the rainfall amount exceeds the rainfall threshold, determine whether a manual braking instruction is received. If a braking instruction is received, a sand scattering start instruction is generated to enhance the braking ability and ensure safety.
