[0001] The present disclosure relates to the field of rail transit technology, and more specifically, to a control method, device, equipment, medium and diesel locomotive for a diesel locomotive. Background Art

When the diesel multiple unit changes from the electric braking state to the coasting state, the energy originally consumed or fed back by the electric braking system will suddenly be transferred to the power system, resulting in a large fluctuation in the engine speed, which affects the service life of the engine.

[0041] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks, servers and internal combustion locomotives may be provided as required.

[0042] Figure 2 The flowchart of the control method of the internal combustion engine vehicle according to the embodiment of the present disclosure is schematically shown. Figure 2 As shown, the method includes operations S201 to S204.

[0043] In operation S201, the current running state of the diesel locomotive is acquired, the current running state includes a traction state, a coasting state and a braking state, and the braking state includes an electric braking state.

[0044] In operation S202, when the current running state of the diesel locomotive is an electric braking state, a first trend graph of changes in engine torque versus engine speed of the diesel locomotive is obtained.

[0045] In operation S203 , a target rotation speed is determined based on the first trend graph.

[0046] In operation S204, the engine speed of the diesel locomotive is adjusted to a target speed.

[0047] According to an embodiment of the present disclosure, when a diesel locomotive changes from an electric braking state to an idling state, energy originally consumed or fed back by the electric braking system will suddenly be transferred to the power system, causing large fluctuations in the engine speed, affecting the service life of the engine.

[0048] Figure 3 A schematic diagram of the operating state of a diesel locomotive according to an embodiment of the present disclosure is schematically shown, wherein the R1 diesel engine and the R2 diesel engine are two engines of the same diesel locomotive.

[0049] like Figure 3 As shown, when the running time of the diesel locomotive is 12:03:15, the train is in a state of transitioning from electric braking to coasting. At this time, the train speed decreases, the grid voltage decreases, the actual speed of the R1 diesel engine and the R2 diesel engine decreases, and the diesel engine load rate increases suddenly.

[0050] In order to reduce the impact of sudden load changes on the engine, the engine speed can be adjusted when the diesel locomotive changes from electric braking state to coasting state to improve the engine's load resistance, thereby reducing the impact of sudden load changes on the engine's service life.

[0051] According to an embodiment of the present disclosure, the engine torque is related to the engine's load resistance. Generally, the greater the engine torque, the stronger the engine's response ability when facing load changes, that is, the stronger the engine's load resistance. There is also a corresponding relationship between the engine torque and the engine speed. Therefore, in order to ensure that the engine has a strong load resistance under electric braking, the target engine torque can be determined first, wherein the target engine torque corresponds to a stronger engine load resistance; and then the target speed is determined based on the target engine torque. As a result, when the engine is running at the target speed, the engine has a strong load resistance, which can effectively reduce the impact of sudden load changes on the engine's service life.

[0052] According to an embodiment of the present disclosure, specifically, in operation S201, the diesel locomotive may have multiple operating states, such as traction state, coasting state and braking state. Among them, the braking state may include an electric braking state. The electric braking state refers to the state in which the diesel locomotive is currently using an electric braking system for braking. Usually, when the speed of the train is above 10 km / h, the train uses the electric braking system for braking.

[0053] According to an embodiment of the present disclosure, in operations S202 to S203, the target speed can be determined based on a pre-constructed first trend graph of the engine torque of a diesel locomotive changing with the engine speed. For example, since the engine has the strongest load resistance when the engine torque is at its maximum, the engine speed corresponding to the maximum engine torque can be read from the first trend graph and used as the target speed.

[0054] According to an embodiment of the present disclosure, in operation S204, after determining the target speed, the engine speed of the diesel locomotive may be adjusted to the target speed, thereby improving the load resistance of the engine in the electric braking state.

[0055] According to an embodiment of the present disclosure, a pre-built engine characteristic curve diagram may be obtained. The engine characteristic curve diagram may include, for example, a first trend diagram of engine torque changing with engine speed, and may also include a schematic diagram of engine output power changing with engine speed.

[0056] Figure 4 A first trend diagram showing changes in engine torque with engine speed according to an embodiment of the present disclosure is schematically shown. Figure 5 A schematic diagram showing the variation of engine output power with engine speed according to the present disclosure is shown schematically.

[0057] like Figure 4 As shown in the figure, for a diesel engine, the speed when its torque reaches the maximum value is 1300rpm. At this time, the load resistance of the diesel engine is the strongest, so the target speed can be determined to be 1300rpm. When the handle of the internal combustion engine is in the braking state, the speed of the diesel engine can be increased to 1300rpm, thereby reducing the impact of the sudden load on the speed of the diesel engine. Figure 5 As shown, for this diesel engine, when the speed is 1300rpm, the output power is 600KW.

[0058] It should be noted that the target speeds of diesel engines of different models may be different. The description of the value of the target speed in the embodiment of the present disclosure is only exemplary and does not limit the value of the target speed in any form.

[0059] The control method of existing diesel locomotives is that when the diesel locomotive is switched to the electric braking state, the engine usually runs at the idle speed. However, the idle speed of the engine installed in the diesel multiple unit is often low, and its load resistance capacity is poor. Specifically, when the train changes from the electric braking state to the coasting state, the energy originally consumed or fed back by the electric braking system will suddenly be transferred to the power system, which will cause the engine speed to fluctuate greatly, thereby affecting the service life of the engine.

[0060] According to the embodiment of the present disclosure, when the current running state of the internal combustion engine locomotive is the electric braking state, the engine speed of the internal combustion engine locomotive is adjusted to the target speed, and the target speed corresponds to the speed when the engine has a strong load resistance, so that the engine speed can be controlled to fluctuate within a reasonable range, so that the engine has a greater load resistance, effectively reducing the impact of sudden load changes on the service life of the engine, and improving the reliability of engine operation. In addition, by determining the target speed based on the first trend graph, the corresponding relationship between the engine torque and the engine speed can be simply and accurately obtained. After determining the target engine torque, the target speed can be accurately determined.

[0061] According to an embodiment of the present disclosure, determining the target rotation speed based on the first trend graph may include operations 11 to 13.

[0062] In operation 11 , a predetermined threshold range of engine torque is determined.

[0063] In operation 12 , an engine speed range corresponding to a predetermined threshold range is read from the first trend map.

[0064] In operation 13 , a target speed is determined based on the engine speed range.

[0065] According to the embodiment of the present disclosure, according to the actual operation requirements of the internal combustion engine, a predetermined threshold range of the engine torque can be first determined. Within the predetermined threshold range, the engine has a strong load resistance. Then, the engine speed range corresponding to the predetermined threshold range is read from the first trend graph.

[0066] According to an embodiment of the present disclosure, determining the target rotation speed based on the first trend graph may further include operations 21 and 22.

[0067] In operation 21 , an engine speed corresponding to when the engine torque is maximum is determined based on the first trend map.

[0068] In operation 22 , the engine speed corresponding to when the engine torque is maximum is used as the target speed.

[0069] According to the embodiment of the present disclosure, since under normal circumstances, the engine has the strongest load resistance when the engine torque is the largest, the engine speed corresponding to the maximum engine torque can be directly read from the first trend graph and used as the target speed. Thus, when the engine speed of the internal combustion locomotive is adjusted to the target speed, the engine can have the strongest load resistance.

[0070] According to an embodiment of the present disclosure, based on the pre-constructed first trend graph, the engine speed corresponding to the maximum engine torque can be accurately read, thereby improving the accuracy of determining the target speed.

[0071] According to an embodiment of the present disclosure, the control method of the above-mentioned diesel locomotive also includes: when the current operating state of the diesel locomotive is a coasting state and the duration of the current operating state exceeds a predetermined time threshold, adjusting the engine speed of the diesel locomotive to an idle speed.

[0072] According to an embodiment of the present disclosure, Figure 3 It can be seen that for a period of time after the diesel locomotive switched to the idling state (the running time was 12:03:15~12:03:18), the engine load rate was still at a relatively high level; as time continued to increase, the engine load rate gradually reached a lower level.

[0073] According to an embodiment of the present disclosure, within a predetermined time threshold, the engine load rate is still at a relatively high level, and the engine still needs to maintain a relatively high load resistance capacity, so the engine speed is still the target speed; when the duration of the idling state exceeds the predetermined time threshold, the engine load rate reaches a relatively low level, and therefore there is no need to maintain a relatively high load resistance capacity, and the engine speed of the diesel locomotive can be adjusted to the idle speed.

[0074] According to an embodiment of the present disclosure, the engine speed of the diesel locomotive is adjusted to the idle speed only when the duration of the idling state exceeds a predetermined time threshold. By deeply exploring the changing law of the engine load rate, the impact of the energy consumed or fed back by the electric braking system on the engine service life when it is suddenly transferred to the power system can be further reduced.

[0075] According to an embodiment of the present disclosure, specifically, a second trend graph of changes in the engine load rate of the diesel locomotive with the running time can be obtained; and based on the second trend graph, a predetermined time threshold is determined.

[0076] For example, after obtaining the second trend graph of the engine load rate of a diesel locomotive changing with the running time, it can be determined based on the second trend graph that the engine load rate of the diesel locomotive is still at a high level when the running time is 12:03:15-12:03:18, and the load rate reaches a low level after 12:03:18. Therefore, the predetermined time threshold can be determined to be 3 seconds.

[0077] According to an embodiment of the present disclosure, the engine load rate can measure the working intensity of the engine within a specific time, which reflects the ratio between the actual output power of the engine and the maximum output power.

[0078] According to an embodiment of the present disclosure, a second trend graph can be pre-constructed to intuitively show the change of the engine load rate with the running time of the diesel locomotive, thereby accurately determining the predetermined time threshold corresponding to when the engine load rate is still at a high level.

[0079] According to an embodiment of the present disclosure, the control method of the above-mentioned diesel locomotive also includes: when the current operating state of the diesel locomotive is a traction state, determining the target traction level corresponding to the current operating state; adjusting the engine speed of the diesel locomotive to the speed corresponding to the target traction level.

[0080] According to an embodiment of the present disclosure, after the diesel locomotive returns to the traction state, the engine speed of the diesel locomotive is adjusted to a speed corresponding to the target traction level so that the diesel locomotive can operate normally.

[0081] Figure 6 A block diagram schematically shows a control device of a diesel locomotive according to an embodiment of the present disclosure.

[0082] like Figure 6 As shown, the control device 600 of the diesel locomotive in this embodiment includes a first acquisition module 610 , a second acquisition module 620 , a first determination module 630 , and a first adjustment module 640 .

[0083] The first acquisition module 610 is used to acquire the current running state of the diesel locomotive, which includes traction state, coasting state and braking state, and the braking state includes electric braking state. In one embodiment, the first acquisition module 610 can be used to perform the operation S201 described above, which will not be repeated here.

[0084] The second acquisition module 620 is used to acquire a first trend graph of engine torque of the diesel locomotive as a function of engine speed when the current running state of the diesel locomotive is the electric braking state. In one embodiment, the second acquisition module 620 can be used to perform the operation S202 described above, which will not be described in detail here.

[0085] The first determination module 630 is used to determine the target rotation speed based on the first trend graph. In one embodiment, the first determination module 630 can be used to perform the operation S203 described above, which will not be described in detail here.

[0087] According to an embodiment of the present disclosure, the first determination module includes a first determination submodule, a first reading submodule and a second determination submodule.

[0088] The first determination submodule is used to determine a predetermined threshold range of the engine torque; the first reading submodule is used to read the engine speed range corresponding to the predetermined threshold range from the first trend graph; and the second determination submodule is used to determine the target speed based on the engine speed range.

[0089] According to an embodiment of the present disclosure, the first determining module includes a third determining submodule.

[0090] The third determination submodule is used to determine the engine speed corresponding to the maximum engine torque based on the first trend graph; and use the engine speed corresponding to the maximum engine torque as the target speed.

[0091] According to an embodiment of the present disclosure, the control device of the diesel locomotive further includes a second adjustment module.

[0092] The second adjustment module is used to adjust the engine speed of the diesel locomotive to the idle speed when the current running state of the diesel locomotive is the coasting state and the duration of the current running state exceeds a predetermined time threshold.

[0093] According to an embodiment of the present disclosure, the second adjustment module further includes an acquisition submodule and a fourth determination submodule.

[0094] The acquisition submodule is used to acquire a second trend graph of the engine load rate of the diesel locomotive changing with the running time; the fourth determination submodule is used to determine a predetermined time threshold based on the second trend graph.

[0095] According to an embodiment of the present disclosure, the control device of the diesel locomotive further includes a second determination module and a third adjustment module.

[0096] The second determination module is used to determine the target traction level corresponding to the current operating state when the current operating state of the diesel locomotive is the traction state; the third adjustment module is used to adjust the engine speed of the diesel locomotive to the speed corresponding to the target traction level.
