DETAILED DESCRIPTION

[0017] Embodiments of the present application are described in detail below, and examples of the embodiments 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 application, and should not be construed as limiting the present application.

[0018] The following describes the abnormal state monitoring method, system and electronic device of an electric locomotive according to the embodiment of the present application with reference to the accompanying drawings.

[0019] Figure 1 The following is a flow chart of a method for monitoring abnormal state of an electric locomotive provided in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps: S101, obtaining the running status of the electric locomotive.

[0020] It is understandable that when the electric locomotive is running, it may experience slipping, abnormal starting or abnormal braking, and when the electric locomotive is stationary, it may experience abnormal conditions such as sliding. Therefore, the current operating state of the electric locomotive is determined as a moving state or a stopped state to monitor different abnormal conditions of the electric locomotive.

[0021] Optionally, the operating state of the electric locomotive may be determined based on a driving device of the electric locomotive, for example, when the driving device is working, the electric locomotive is determined to be in a moving state, and when the driving device is stationary, the electric locomotive is determined to be in a stopped state.

[0022] S102, determining whether the running state of the electric locomotive is a stopped state or a moving state.

[0023] S103, in response to the running state of the electric locomotive being the stopped state, acquiring stationary information of the electric locomotive, and determining, according to the stationary information, first indication information of whether the electric locomotive has a slipping abnormality.

[0024] It can be understood that the stop state is a state in which the electric locomotive is stationary and not moving; optionally, the stop information may include the position information of the electric locomotive, and whether the electric locomotive is slipping is determined based on changes in the position information of the electric locomotive. For example, the first position of the electric locomotive when it is stationary is recorded, and the second position of the electric locomotive after a preset time period is obtained. When the first position is the same as the second position or the error is within a preset range, it is determined that the electric locomotive has been stationary and there is no slipping abnormality. Correspondingly, when the error between the first position and the second position exceeds the preset range, it is determined that the electric locomotive has a slipping abnormality.

[0025] It can be understood that the first indication information includes an indication that the electric locomotive has a slipping abnormality or that the electric locomotive does not have a slipping abnormality.

[0026] S104, in response to the operating state of the electric locomotive being a moving state, obtaining operating information of the electric locomotive.

[0027] It can be understood that the motion state is the state in which the electric locomotive is running and moving; optionally, the running information at least includes the running speed of the driving wheel, the running speed of the driven wheel and the running speed of the whole vehicle of the electric locomotive.

[0028] S105, determining second indication information of whether the electric locomotive has a slip abnormality according to the running speed of the driving wheel and the running speed of the driven wheel.

[0029] In some implementations, when the running speed of the entire vehicle reaches a certain threshold, it is determined whether the running speed of the driving wheel and the running speed of the driven wheel are consistent. If the running speed of the driving wheel is different from the running speed of the driven wheel, it is determined that the electric locomotive has a slip abnormality; correspondingly, if the running speed of the driving wheel is the same as the running speed of the driven wheel, it is determined that the electric locomotive does not have a slip abnormality.

[0030] It can be understood that the second indication information includes an indication that the electric locomotive has a slip abnormality or that the electric locomotive does not have a slip abnormality.

[0031] S106, determining whether the electric locomotive has third indication information of abnormal starting according to the running speed of the entire vehicle.

[0032] In some implementations, the starting abnormality of an electric locomotive refers to an abnormal state that exists when the electric locomotive starts running. If the whole vehicle running speed does not change or changes very little when the electric locomotive starts, it can be determined that the electric locomotive has a starting abnormality; accordingly, if the electric locomotive reaches the normal whole vehicle running speed within a preset time, it is determined that the electric locomotive does not have a starting abnormality.

[0033] It can be understood that the third indication information includes indicating that there is a startup abnormality in the electric locomotive or that there is no startup abnormality in the electric locomotive.

[0034] S107, determining, based on the running speed of the driven wheels, whether the electric locomotive has fourth indication information indicating abnormal parking.

[0035] In some implementations, parking abnormality refers to an abnormal state of the electric locomotive when braking. If the electric locomotive determines whether the running speed of the driven wheel is reduced to zero within a preset time after issuing a brake signal, if the running speed of the driven wheel becomes zero within the preset time, it is determined that there is no parking abnormality of the electric locomotive. Otherwise, if the running speed of the driven wheel does not become zero within the preset time, it is determined that there is a parking abnormality of the electric locomotive.

[0036] It can be understood that the fourth indication information includes indicating that the electric locomotive has a parking abnormality or that the electric locomotive does not have a parking abnormality.

[0037] S108, determining abnormal information of the electric locomotive according to the first indication information, the second indication information, the third indication information and the fourth indication information.

[0038] It can be understood that the abnormal information of the electric locomotive can be determined based on the first indication information, the second indication information, the third indication information or the fourth indication information. The abnormal information may include whether the electric locomotive has abnormal slipping, sliding, starting and stopping, thereby improving the real-time monitoring effect of the electric locomotive.

[0039] In the present embodiment, different operating states of the electric locomotive are monitored for abnormalities. When the electric locomotive is in a stopped state, whether there is a slipping abnormality is determined by the stopping information of the electric locomotive. When the electric locomotive is in a moving state, whether there is a slipping abnormality is determined by obtaining the driving wheel running speed and the driven wheel running speed of the electric locomotive. Whether there is a starting abnormality of the electric locomotive is determined by the whole vehicle running speed of the electric locomotive, and whether there is a parking abnormality of the electric locomotive is determined according to the driven wheel running speed. Thus, according to the indication information corresponding to each abnormality type, the abnormal information of the electric locomotive is determined, so as to comprehensively monitor the state of the electric locomotive, obtain the abnormal state of the electric locomotive more timely and accurately, and ensure the safe operation of the electric locomotive.

[0040] Based on the above embodiments, Figure 2 A flow chart of another method for monitoring abnormal state of an electric locomotive provided in an embodiment of the present application. Figure 2 As shown, the method comprises the following steps: S201, obtaining the running status of the electric locomotive.

[0041] In some implementations, before acquiring the state of the electric locomotive, a zero-point calibration may be performed on the electric locomotive to acquire more accurate information related to the electric locomotive.

[0042] In the embodiment of the present application, the implementation method of S201 can be implemented by any of the methods in the embodiments of the present disclosure, which is not limited here and will not be repeated.

[0043] S202, determining whether the running state of the electric locomotive is a stopped state or a moving state.

[0044] S203, in response to the running state of the electric locomotive being the stopped state, acquiring stationary information of the electric locomotive, and determining, according to the stationary information, first indication information of whether the electric locomotive has a slipping abnormality.

[0045] In some implementations, the first absolute position of the electric locomotive when it is initially stationary and the second absolute position after a preset period can be determined based on the stationary information; optionally, the absolute position can be calculated as: absolute position S = (encoder pulse number Q / encoder resolution p) * wheel circumference L, where the encoder is arranged on the driven wheel of the electric locomotive to obtain the rotation information of the driven wheel to calculate the driving information of the electric locomotive.

[0046] The deviation absolute position is determined based on the first absolute position and the second absolute position; that is, the absolute value of the difference between the initial first absolute position and the second absolute position after a preset period is determined as the deviation absolute position. In response to the deviation absolute position being greater than or equal to the preset distance, it is determined that the first indication information indicates that the electric locomotive has a slipping abnormality; in response to the deviation absolute position being less than the preset distance, it is determined that the first indication information indicates that the electric locomotive does not have a slipping abnormality.

[0047] In this embodiment, the preset period can be 2 seconds, and the preset distance can be 10 mm. That is, when the electric locomotive moves a distance exceeding 10 mm within 2 seconds, it is determined that the electric locomotive has a slipping abnormality. Otherwise, it is determined that the electric locomotive does not have a slipping abnormality. In other embodiments, the preset period and preset distance can be adjusted, and the details are not repeated here.

[0048] S204, in response to the operating state of the electric locomotive being a moving state, obtaining operating information of the electric locomotive.

[0049] In some implementations, the running speed in the running information is determined by the difference between the mileage and the calculation cycle, and the mileage is obtained by the absolute position before and after the counting cycle, that is, when the electric locomotive is running, after a counting cycle T, the absolute positions S1 and S2 fed back before and after the counting cycle T are determined, and the absolute value of the difference S1-S2 before and after is taken to obtain the mileage, and the running speed is obtained according to the ratio of the mileage and the counting cycle T, that is, the running speed is |S1-S2| / T, |S1-S2| represents the absolute value of the difference.

[0050] In some implementations, the driving wheel running speed can be calculated by an inverter of the electric locomotive, and the driven wheel running speed can be calculated by an encoder through the rotation information of the driven wheel.

[0051] In the embodiment of the present application, the implementation method of S204 can be implemented by any of the methods in the embodiments of the present disclosure, which is not limited here and will not be repeated.

[0052] S205, determining an absolute difference between the running speed of the driving wheel and the running speed of the driven wheel, and determining second indication information of whether the electric locomotive has a slip abnormality according to the absolute difference.

[0053] In this embodiment, when the electric locomotive is traveling and the running speed reaches above the first gear, the absolute difference between the running speeds of the driving wheel and the driven wheel is determined. The smaller the absolute difference, the closer the running speeds of the driving wheel and the driven wheel are. Conversely, the larger the absolute difference, the greater the difference between the running speeds of the driving wheel and the driven wheel.

[0054] In response to the absolute difference being greater than or equal to a preset difference, it is determined that the second indication information indicates that the electric locomotive has a slip abnormality; in response to the absolute difference being less than the preset difference, it is determined that the second indication information indicates that the electric locomotive does not have a slip abnormality.

[0055] Optionally, the preset difference may be 0.01 m / s.

[0056] S206, obtaining the first target time, and determining the whole vehicle running speed of the electric locomotive after the first target time, and determining whether the electric locomotive has third indication information of abnormal startup according to the whole vehicle running speed.

[0057] In some implementations, the first target time can be determined based on a preset excitation time, a preset acceleration time, and a first preset speed; wherein the excitation time refers to the time required for the motor or device in the excitation process, that is, the time required for the motor to start and enter a stable working state. In this embodiment, the preset excitation time is denoted as t1, the preset acceleration time is denoted as t2, and the first preset speed is the operating speed V of the locomotive in the first gear. The first target time can be expressed as tm1=t1+V*t2 / 50+1, where the constant term "1" is set based on experience and can be adjusted in other embodiments.

[0058] In some implementations, the whole vehicle running speed after tm1 time after the electric locomotive is started can be obtained, and in response to the whole vehicle running speed being greater than or equal to the first preset speed, it is determined that the third indication information indicates that the electric locomotive has started normally, wherein the first preset speed can be the running speed V of the electric locomotive when it reaches the first gear, that is, after tm1 time, the whole vehicle running speed of the electric locomotive reaches the first preset speed V, and it is determined that the electric locomotive has started normally; accordingly, in response to the whole vehicle running speed being less than the first preset speed, it is determined that the third indication information indicates that the electric locomotive has started abnormally, that is, after tm1 time, the whole vehicle running speed of the electric locomotive has not reached the first preset speed V, and it is determined that the electric locomotive has started abnormally.

[0059] S207, obtaining the second target time, and determining the running speed of the driven wheels after the second target time, and determining fourth indication information of whether the electric locomotive has parking abnormality according to the running speed of the driven wheels.

[0060] In some implementations, the response time of normal braking can be obtained, and the second target time can be obtained based on the sum of the response time and a preset value; optionally, the second target time can be expressed as tm2=tz+0.5, where tz is the response time of normal braking, and the constant term "0.5" is set based on experience and can be adjusted in other embodiments.

[0061] In some implementations, the running speed of the driven wheel tm2 time after the brake signal appears in the electric locomotive can be obtained, and in response to the driven wheel running speed being equal to the second preset speed, it is determined that the fourth indication information indicates that the electric locomotive has stopped normally; wherein the second preset speed is 0, that is, the running speed of the driven wheel becomes 0 tm2 time after the brake signal appears in the electric locomotive, then it is determined that the electric locomotive has stopped normally; accordingly, in response to the running speed of the driven wheel not being equal to the second preset speed, it is determined that the fourth indication information indicates that the electric locomotive has stopped abnormally, that is, the running speed of the driven wheel has not become 0 tm2 time after the brake signal appears in the electric locomotive, then it is determined that the electric locomotive has stopped abnormally.

[0062] S208, determining abnormal information of the electric locomotive according to the first indication information, the second indication information, the third indication information and the fourth indication information.

[0063] It can be understood that if the first indication information indicates that the electric locomotive has a slipping abnormality, and the second indication information, the third indication information and the fourth indication information all indicate that the electric locomotive has no abnormality, then the abnormal information of the electric locomotive is the existence of a slipping abnormality; similarly, if the first indication information indicates that the electric locomotive has a slipping abnormality, the second indication information indicates that the electric locomotive has a skidding abnormality, and the third indication information and the fourth indication information both indicate that the electric locomotive has no abnormality, then the abnormal information of the electric locomotive is the existence of a slipping abnormality and a skidding abnormality, and so on.

[0064] In some implementations, corresponding abnormal alarm information can also be issued based on the abnormality type in the abnormal information. For example, when the electric locomotive has a slipping abnormality, a slipping abnormality alarm is issued, and when the electric locomotive has a starting abnormality, a starting abnormality alarm is issued, so as to remind relevant personnel to pay attention to the abnormal situation of the electric locomotive in time and ensure that the electric locomotive can operate safely.

[0065] In the present embodiment, abnormality monitoring is performed on different operating states of the electric locomotive. When the electric locomotive is in a stopped state, whether there is a slipping abnormality is determined by the stop information of the electric locomotive. When the electric locomotive is in a moving state, whether there is a slipping abnormality of the electric locomotive is determined by obtaining the absolute difference between the driving wheel running speed and the driven wheel running speed of the electric locomotive, thereby improving the accuracy of monitoring the slipping abnormality. Further, a first target time is obtained, and whether there is a starting abnormality of the electric locomotive is determined based on the whole vehicle running speed after the first target time. A second target time is obtained, and whether there is a parking abnormality of the electric locomotive is determined based on the driven wheel running speed after the second target time, thereby improving the monitoring accuracy of the starting state of the electric locomotive. Therefore, according to the indication information corresponding to each abnormality type, the abnormal information of the electric locomotive is determined and the corresponding abnormal alarm is performed, so as to remind relevant personnel to pay attention to the abnormal situation of the electric locomotive in time, comprehensively monitor the state of the electric locomotive, and ensure the safe operation of the electric locomotive.

[0066] In order to implement the above embodiments, the present application also proposes an abnormal state monitoring system for an electric locomotive.

[0067] Figure 3 The following is a schematic diagram of the structure of an abnormal state monitoring system for electric locomotives provided in an embodiment of the present application. Figure 3 As shown, including: Power motors, electric locomotives, encoders, inverters and programmable logic controllers (PLCs).

[0068] The power motor is arranged on the driving wheel of the electric locomotive to drive the driving wheel to move.

[0069] The inverter is located in the electric control box of the electric locomotive, and is used to drive the power motor and obtain the driving wheel speed of the electric locomotive, and send the driving wheel speed to the PLC; The encoder is arranged on the driven wheel of the electric locomotive and is used to obtain the driving information of the electric locomotive and send the driving information to the PLC, wherein the driving information includes the static information and motion information of the electric locomotive, and the motion information at least includes the running speed of the driven wheel of the electric locomotive and the running speed of the whole vehicle.

[0070] The PLC is used to receive the driving information of the electric locomotive and obtain the operating status of the electric locomotive, which includes a moving state and a stopped state; in response to the operating status of the electric locomotive being a stopped state, first indication information is used to determine whether the electric locomotive has a slipping abnormality based on the stationary information; in response to the operating status of the electric locomotive being a moving state, second indication information is used to determine whether the electric locomotive has a slipping abnormality based on the operating speed of the driving wheel and the operating speed of the driven wheel; third indication information is used to determine whether the electric locomotive has a starting abnormality based on the operating speed of the entire vehicle; fourth indication information is used to determine whether the electric locomotive has a parking abnormality based on the operating speed of the driven wheel; and abnormal information of the electric locomotive is determined based on the first indication information, the second indication information, the third indication information and the fourth indication information.

[0071] In some implementations, the input / output port of the PLC is connected to a button / knob / handle, and the communication port is connected to the touch screen of the electric locomotive; a zero point button or a physical self-reset button can be set on the touch screen to set the absolute value of the encoder feedback to 0, set the zero point of the encoder for zero point correction, and perform more accurate electric locomotive abnormality analysis.

[0072] In some implementations, the driven wheels of the electric locomotive follow the movement of the driving wheels, and the braking system is a pneumatic brake pad that hugs the wheels.

[0073] It should be noted that the above explanations of the embodiment of the method for monitoring the abnormal state of an electric locomotive are also applicable to the system for monitoring the abnormal state of an electric locomotive in this embodiment, and will not be repeated here.

[0074] In the embodiment of the present application, an encoder is arranged on the driven wheel of the electric locomotive to obtain the driving information of the electric locomotive, and the PLC analyzes the driving information. When the electric locomotive is in a stopped state, whether there is a slipping abnormality is determined by the stop information of the electric locomotive. When the electric locomotive is in a moving state, whether there is a slipping abnormality in the electric locomotive is determined by obtaining the absolute difference between the running speed of the driving wheel and the running speed of the driven wheel of the electric locomotive, thereby improving the accuracy of monitoring the slipping abnormality, further obtaining a first target time, and determining whether there is a starting abnormality in the electric locomotive based on the running speed of the whole vehicle after the first target time, obtaining a second target time, and determining whether there is a parking abnormality in the electric locomotive based on the running speed of the driven wheel after the second target time, thereby improving the monitoring accuracy of the starting state of the electric locomotive, comprehensively monitoring the state of the electric locomotive, and ensuring the safe operation of the electric locomotive.
