Description

Technical Field

[0001] The present invention relates to the technical field of railway locomotives and vehicles, and in particular to a traction / braking handling system and method for a central locomotive of a heavy-duty locomotive. Background Art

[0002] The traction / brake signal from the head locomotive of the combined train is sent to the middle locomotive via wireless transmission. After receiving the traction / brake command from the head locomotive, the middle locomotive performs the corresponding action synchronously. Taking the starting stage of the combined train as an example, due to the long distance between the head locomotive and the middle locomotive, the vehicle in front of the middle locomotive is still stationary when the middle locomotive generates traction / brake action. At this time, the traction force generated by the middle locomotive and the stationary vehicle in front form a squeeze, which may cause problems such as the end coupler of the middle locomotive being unhooked. In general, when the operating conditions of the combined train change, the inconsistency between the running status of the middle locomotive and the vehicle in front of the middle locomotive is likely to cause impulse and unevenness between the middle locomotive and the vehicle in front of the middle locomotive.

[0003] In addition, when the signal of the combined train is interrupted during operation, the middle locomotive will gradually reduce the traction / electric braking force to 0 after maintaining the state before the communication interruption for a period of time. There are two main problems with this control method: 1) When the combined train is on an uphill line, due to the unloading of the traction force of the middle locomotive, the traction force of the head locomotive alone may not be able to pass through the uphill section, causing the combined train to stop on the slope; 2) When the combined train is on a downhill line, the locomotive uses electric braking force to adjust the speed of the combined train. When the communication between the head locomotive and the middle locomotive is abnormal, the middle locomotive will reduce the electric braking force to 0. At this time, the electric braking force of the head locomotive alone may not meet the speed regulation requirements of the combined train on the downhill line. At the same time, due to the sudden unloading of the electric braking force of the middle locomotive, it takes a long time for the electric braking force generated by the head locomotive to be transmitted to the rear vehicle through the coupler, and the speed difference between the vehicles will also cause impulse problems between the vehicles.

[0004] Therefore, it is an urgent problem to be solved by those skilled in the art to provide a heavy-duty locomotive mid-locomotive traction / braking handling system and method that can effectively solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The embodiments of the present invention are written in a progressive manner.

[0021] The embodiment of the present invention provides a heavy-duty locomotive middle locomotive traction / braking disposal system and method, which mainly solves the technical problem in the prior art that the middle locomotive traction / braking safety is low, resulting in the risk of the end hook being unhooked.

[0022] like Figure 1 As shown, a heavy-load locomotive middle locomotive traction / brake handling system includes: a sensor processing device, a TCMS device, a head locomotive command sending device and a middle locomotive traction brake device; The TCMS device is connected to the command sending device, sensor processing device of the head locomotive and the traction brake device of the middle locomotive respectively; The sensor processing device is installed at the coupler of the middle locomotive, and is used to obtain and process the coupler force data of the middle locomotive, obtain the processed coupler force data and send it to the TCMS device; The head locomotive command sending device, when in normal state, is used to send traction / braking commands to the TCMS device; The TCMS device is used to formulate the traction / braking strategy of the central locomotive according to the traction / braking command and the processed coupler force data after receiving the traction / braking command and the processed coupler force data; The central locomotive traction brake device is used to perform corresponding traction / braking actions on the central locomotive according to the central locomotive traction / braking strategy.

[0023] During actual use, the TCMS device is connected to the command sending device of the head locomotive, the traction and braking device of the middle locomotive, and the sensor processing device. The sensor processing device detects and obtains the coupler force data of the middle locomotive and processes the data accordingly to obtain the processed coupler force data; when the command sending device of the head locomotive is in a normal state, it sends a traction / braking command to the TCMS device. When the TCMS device receives the traction / braking command and the processed coupler force data, it formulates a traction / braking strategy for the middle locomotive according to the command and data, and executes the strategy after the strategy is formulated to achieve traction / braking of the middle locomotive.

[0024] It should be noted that TCMS is the abbreviation of Train Control and Management System. The full name of TCMS is Locomotive Microcomputer Control and Monitoring System. The main function is to realize locomotive characteristic control, logic control, fault monitoring and self-diagnosis, and transmit information to the microcomputer display screen on the driver's console to give the driver an intuitive reflection of the real-time status of the locomotive. TCMS includes 1 main control device and 2 display units. The main CPU adopts a redundant design and is equipped with two sets of control links, one for the main control link and the other for the hot standby control link. When the main control link fails, it is automatically cut off, and the standby control link is automatically put into operation immediately.

[0025] Preferably, When the command sending device of the head locomotive is in an abnormal state, the TCMS device is also used to formulate the traction / braking strategy of the middle locomotive based on the processed coupler force data.

[0026] During actual operation, when the communication of the combined train is abnormal, due to the abnormal wireless reconnection communication, the CRRC locomotive cannot receive the traction / braking command issued by the command sending device of the head locomotive. Instead of directly unloading the traction force or electric braking force by the middle locomotive as in the existing combined train, the TCMS formulates the locomotive traction / braking strategy based on the data collected by the coupler force sensor and executes it according to the strategy until the train stops smoothly.

[0027] like Figure 2 As shown, preferably, The TCMS device includes: a judgment module; The judgment module is used to determine whether the processed coupler force data has been received when the TCMS device receives the traction / braking command.

[0028] During actual use, a judgment module is provided in the TCMS device. When the TCMS device receives a traction / braking command sent by the head locomotive command sending device, the judgment module is started to judge whether the TCMS device has received the processed coupler force data.

[0029] Preferably, The TCMS device includes: an execution module; The execution module is used to execute different strategies according to the judgment results.

[0030] In actual use, the TCMS device is further provided with an execution module, which is connected to the judgment module and executes different strategies according to different judgment results of the judgment module.

[0031] Preferably, the execution module is specifically used to, when the TCMS device has received the traction / braking command but has not received the processed coupler force data, execute the silent strategy until the processed coupler force data is received; The specific silent strategy is: control the central locomotive to change to idling mode and maintain silent waiting.

[0032] Preferably, the execution module is specifically used to execute the corresponding traction / braking strategy when the TCMS device has received the traction / braking command and the processed coupler force data; The specific traction / braking strategy is: control the middle locomotive to perform electric traction / braking, and the magnitude of the electric traction / braking force provided is consistent with that of the leading locomotive.

[0033] During actual operation, when the TCMS device receives instructions but does not receive the coupler force data, the silent strategy is executed. Specifically, the middle locomotive is controlled to change to the idling mode (traction force is reduced to 0), and the silent waiting is maintained until the TCMS device receives the coupler force data; when the TCMS device has received the instructions and the processed coupler force data, the conditions are met and the middle locomotive is controlled to perform electric traction / braking. The traction / braking force provided is consistent with that of the head locomotive.

[0034] like Figure 3 As shown, a method for traction / braking of a heavy-load locomotive in the middle of the locomotive comprises the following steps: S1. Obtain and process the coupler force data of the central locomotive, obtain the processed coupler force data and send it to the TCMS device; S2. When the head locomotive command sending device is in normal state, it is used to send traction / braking commands to the TCMS device; S3. After receiving the traction / braking command and the processed coupler force data, the TCMS device formulates the central locomotive traction / braking strategy according to the traction / braking command and the processed coupler force data; S4. The central locomotive traction brake device performs corresponding traction / braking actions on the central locomotive according to the central locomotive traction / braking strategy.

[0035] Preferably, after step S1, the method further includes: When the command sending device of the leading locomotive is in an abnormal state, the TCMS device formulates the traction / braking strategy of the middle locomotive based on the processed coupler force data.

[0036] The specific implementation process of the steps disclosed in step S1 to step S4 is the function realized by each module in the system, belongs to the same inventive concept as the system, has the same beneficial effects, and will not be repeated here.
