Detailed Description
In order to facilitate understanding and explaining the technical solutions provided by the embodiments of the present application, the following description will first describe the background art of the present application.
The inventor researches a traditional wheel locking fault diagnosis method and finds that the traditional wheel locking fault judgment method is judged by a brake system, the brake system acquires the state information of a wheel, and the wheel locking fault judgment is carried out according to the state information of the wheel. However, since the running environment of the train is complex, the transmission of the signal may be affected by the environment, and the state information of the wheel acquired by the brake system may be interfered. The brake system may determine the state of the wheel incorrectly by using the disturbed wheel state information, which results in incorrect control over the operation of the train and influences the normal operation of the train.
Based on this, the embodiment of the present application provides a method for determining a wheel locking fault, which may be applied to a wheel locking fault determination system having a network system and a braking system. The brake system acquires second state information; wherein the second state information is state information of a wheel; judging whether the wheel has a locking fault according to the second state information; if the wheels have locking faults, fault confirmation information is sent to the network system; the network system acquires first state information; wherein the first status information is status information of the wheel provided by a traction system; the network system judges whether the wheel has a locking fault according to the first state information; the network system judges whether fault confirmation information sent by the brake system is received or not; and if the wheel has a locking fault and receives fault confirmation information sent by the braking system, the network system sends fault reporting information.
The technical solution provided by the embodiment of the present application is easy to understand, and the following describes a wheel locking fault determination method provided by the embodiment of the present application with reference to the accompanying drawings.
Since the wheel locking fault determination method provided by the embodiment of the present application is applied to a network system and a braking system, in order to better understand the wheel locking fault determination method provided by the embodiment of the present application, the wheel locking fault determination method applied to the network system and the wheel locking fault determination method applied to the braking system are integrated into a method embodiment for description, and the method embodiment applied to the network system or the braking system is not separately described.
The braking system is a system with a braking function in a train running system; the network system is a system for transmitting data among the systems, and can realize the acquisition of information generated by each system and the analysis and judgment of the information. In a possible implementation manner, the network system may specifically be a central control system in the train operation system.
Referring to fig. 1, a flowchart of a wheel locking fault determination method provided in an embodiment of the present application is shown, where the method includes steps S101 to S106.
S101: the brake system acquires second state information; wherein the second state information is state information of a wheel; and judging whether the wheel has a locking fault or not according to the second state information.
And the braking system acquires the second state information so as to judge whether the wheel has a locking fault or not. The braking system can directly acquire the state information of the wheel, namely the second state information, and judge whether the wheel has a locking fault according to the second state information.
The second state information may include an axle speed signal of the wheel, and the braking system may determine whether the wheel has a locking fault through the axle speed signal of the wheel. Specifically, the step of judging whether the wheel has a locking fault by the braking system according to the second state information includes:
judging whether the axle speed signal of the wheel is instantaneously disconnected; if the axle speed signal of the wheel is instantaneously disconnected, the wheel is in a locking fault; and if the shaft speed signal of the wheel is not instantaneously disconnected, the wheel is not locked.
It should be noted that the momentary interruption of the shaft speed signal may refer to a momentary interruption of the shaft speed signal. When the axle speed signal in the second state information acquired by the brake system is interrupted instantaneously, the axle speed of the wheel can be indicated to stop, namely, the wheel has a locking fault. However, in the actual train running process, because the running environment is complex, the axle speed signal may be interfered by communication, so that the brake system cannot receive the axle speed signal, and the wheel locking fault is misjudged.
S102: and if the wheels have locking faults, sending fault confirmation information to the network system.
When the brake system judges that the wheel has the locking fault, fault confirmation information is sent to the network system, so that whether the wheel has the locking fault or not is judged through the network system. By sending the fault confirmation information to the network system, whether the wheel has the locking fault or not can be confirmed through the network system, and the accuracy of judging the wheel has the locking fault is improved.
S103: the network system acquires first state information; wherein the first status information is status information of the wheel provided by a traction system.
The network system acquires the state information of the wheels, i.e., the first state information, through the traction system. It is understood that the traction system has status information of the wheels. The network system acquires the state information of the wheels through the traction system, and can prevent the situation that whether the wheels are locked or not is judged wrongly because the network system is consistent with a way of acquiring the state information of the wheels through the brake system.
It should be noted that, in the embodiment of the present application, the execution sequence between S101 and S103 is not limited, and the acquisition of the second state information by the brake system and the acquisition of the first state information by the network system may be performed simultaneously.
S104: and the network system judges whether the wheel has a locking fault according to the first state information.
The operating state of the wheels can be determined by the first state information acquired by the traction system. The first state information may include an axle speed corresponding to the wheel, and whether the wheel is operating normally may be determined according to the axle speed corresponding to the wheel. Specifically, the determining, by the network system, whether the wheel has a locking fault according to the first state information includes:
judging whether the axle speed corresponding to the wheel in the first state information accords with a preset axle speed or not;
if the axle speed corresponding to the wheel in the first state information accords with a preset axle speed, the wheel does not have a locking fault;
and if the axle speed corresponding to the wheel in the first state information does not accord with the preset axle speed, the wheel has a locking fault.
In order to determine whether the wheel has a locking fault, a preset axle speed may be set to indicate the axle speed when the wheel is operating normally. The network system can judge whether the wheels have locking faults or not through the relative relation between the axle speed in the first state information and the preset axle speed.
S105: and the network system judges whether fault confirmation information sent by the brake system is received.
It should be noted that, in order to ensure that the network system and the brake system confirm after the wheel has the lock failure, the network system needs to determine whether to receive the failure confirmation information of the brake system, so as to report the subsequent failure.
In the embodiment of the present application, the order between S105 and S104 is not limited. In a possible implementation manner, after the network system acquires the first state information, it may directly determine whether a locking fault occurs in the wheel, and then determine whether a fault confirmation information sent by the brake system is received. In another possible implementation manner, the network system may determine whether the locking fault occurs in the wheel after receiving the fault confirmation message sent by the braking system. Correspondingly, the embodiment of the application provides two wheel locking fault judgment methods, and specific embodiments are shown in the following.
S106: and if the wheel has a locking fault and receives fault confirmation information sent by the braking system, the network system sends fault reporting information.
When the network system judges that the wheel has the locking fault and receives fault confirmation information sent by the braking system, the network system and the braking system both determine that the wheel has the locking fault and need to send fault reporting information so that the running system of the train can confirm that the wheel has the locking fault and adopt corresponding safety measures.
Based on the contents of S101 to S106, in the embodiment of the present application, the braking system and the network system respectively obtain the state information of the wheel in different manners, and correspondingly determine whether the locking fault occurs in the wheel. And if the braking system judges that the wheels have the locking fault, sending fault confirmation information to the network system. And the network system judges that the wheel has a locking fault and sends fault reporting information after receiving the fault confirmation information. Therefore, the braking system and the network system have different modes for acquiring the wheel state information, whether the wheel has the locking fault is judged through the braking system and the network system, whether the wheel has the locking fault can be judged from two aspects, and a more accurate judgment result of the wheel locking fault is obtained.
The embodiment of the present application provides two methods for determining a wheel locking failure, corresponding to different execution sequences of S104 and S105.
In a possible implementation manner, in order to quickly determine the wheel locking fault, after the network system acquires the first state information, the network system may directly determine whether the wheel locking fault occurs, so as to directly send the fault reporting information after acquiring the fault confirmation information.
Referring to fig. 2, a flowchart of another wheel locking fault determination method provided in the embodiment of the present application is shown, where the method includes steps S201 to S206.
S201: the brake system acquires second state information; wherein the second state information is state information of a wheel; and judging whether the wheel has a locking fault or not according to the second state information.
S202: and if the wheels have locking faults, sending fault confirmation information to the network system.
S203: the network system acquires first state information; wherein the first status information is status information of the wheel provided by a traction system.
The contents of S201-S203 are the same as those of S101-S103, and are not described herein again.
S204: after the first state information is acquired, the network system judges whether the wheel has a locking fault or not according to the first state information.
After the first state information is acquired, the network system judges whether the wheel has a locking fault according to the first state information, and if the wheel is judged to have the locking fault, the network system marks the wheel with a fault.
S205: and if the wheels have locking faults, the network system judges whether fault confirmation information sent by the braking system is received.
After the wheel locking fault is judged, the network system judges whether fault confirmation information sent by the brake system is received or not so as to determine whether the brake system confirms that the wheel locking fault occurs or not.
S206: and if the network system receives the fault confirmation information sent by the braking system, the network system sends fault reporting information.
If the network system receives the fault confirmation information sent by the braking system after judging that the wheel has the locking fault, the network system indicates that the braking system confirms that the wheel has the locking fault, and the network system sends the fault reporting information so that the running system of the train can execute corresponding safety measures.
In the embodiment of the application, the network system judges the wheel state information in real time so as to directly report the fault after receiving the brake system, thereby improving the speed of judging the wheel fault, timely judging the locking fault and obtaining a more accurate judgment result.
In one possible case, the network system determines that the wheel has not suffered a locking failure, but may receive a failure confirmation message sent by the brake system. Another wheel locking fault determination method provided in the embodiment of the present application may further include the following steps:
if the wheel has no locking fault, the network system sends feedback information to the braking system after receiving fault confirmation information sent by the braking system, so that the braking system can determine whether the wheel has the locking fault.
The feedback information comprises information that the network system confirms that the wheels are not locked, and the braking system determines whether the wheels are locked again after acquiring the feedback information, so that the operation accident caused by the fact that the locking fault of the wheels cannot be determined due to misjudgment of the network system is avoided.
The braking system determines whether the wheel has a locking fault, and specifically comprises the following steps:
if the braking system receives feedback information sent by the network system, judging whether the duration time of the locking fault of the wheel is longer than preset time;
and if the duration time of the locking fault of the wheel is longer than the preset time, determining that the locking fault of the wheel occurs, and sending fault reporting information.
It will be appreciated that the braking system determines whether a locking fault has occurred in the wheel based on whether a momentary interruption in the axle speed signal has occurred in the second status information. If the network system judges that the wheel has no locking fault, the braking system can determine whether the wheel has the locking fault by judging whether the duration time of the wheel having the locking fault is longer than the preset time. If the shaft speed signal is instantaneously broken due to interference, the shaft speed signal can be recovered to be normal within the preset time, if the duration time of the instantaneous interruption of the shaft speed signal is longer than the preset time, the operation of the wheels is failed, and the brake system sends failure report information so as to execute subsequent safety measures.
In the embodiment of the application, if the network system confirms that the wheel has no locking fault, the network system sends feedback information to the braking system, so that the braking system determines whether the wheel has the locking fault according to the duration time of the locking fault. The problem that the judgment result of the locking fault of the wheel is inaccurate due to misjudgment of a network system can be avoided, the judgment accuracy of the locking fault of the wheel is improved, and the safe operation of the train is guaranteed.
In another possible implementation manner, in view of the fact that the probability of the occurrence of the wheel locking fault is small, the speed of determining whether the wheel locking fault occurs by the network system is fast, and in order to save the computing resources of the network system, the determination of whether the wheel locking fault occurs may be performed after the network system receives the fault confirmation information.
Referring to fig. 3, which is a flowchart illustrating another method for determining a wheel locking fault according to an embodiment of the present application, the method includes steps S301 to S306.
S301: the brake system acquires second state information; wherein the second state information is state information of a wheel; and judging whether the wheel has a locking fault or not according to the second state information.
S302: and if the wheels have locking faults, sending fault confirmation information to the network system.
S303: the network system acquires first state information; wherein the first status information is status information of the wheel provided by a traction system.
The contents of S301-S303 are the same as those of S101-S103, and are not described herein again.
S304: and the network system judges whether fault confirmation information sent by the brake system is received.
After the first state information is acquired, the network system does not judge whether the wheels have locking faults in real time. And after receiving fault confirmation information sent by the brake system, judging whether the wheels have locking faults or not.
S305: and if the network system receives the fault confirmation information sent by the braking system, judging whether the wheels have locking faults or not according to the first state information.
And after the network system receives the fault confirmation information sent by the brake system, the brake system confirms that the wheel has a locking fault, and the network system further judges.
S306: and if the wheel has a locking fault, sending fault reporting information.
And if the network system judges that the wheels have the locking fault, sending fault reporting information so that a running system of the train can execute corresponding safety measures.
In the embodiment of the application, after the network system acquires the fault confirmation information sent by the brake system, the network system determines whether the wheel has a locking fault. The time for judging by the network system is short, so that the influence on the time of wheel locking faults is small. Therefore, the computing resource of the network system can be saved, and the computing resource of the network system is saved on the basis of ensuring the accuracy of wheel locking fault judgment.
In a possible case, after the network system receives the failure confirmation information sent by the brake system, it may be determined that the wheel locking failure has not occurred. Another wheel locking fault determination method provided in the embodiment of the present application may further include the following steps:
and if the wheel has no locking fault, sending feedback information to the braking system so that the braking system can determine whether the wheel has the locking fault.
The method for the network system to send feedback information to the braking system and the braking system to determine whether the wheel has the locking fault in this step is consistent with the above embodiments, and will not be described herein again.
In the embodiment of the application, if the network system confirms that the wheel has the locking fault after the braking system confirms that the wheel has the locking fault, the network system sends feedback information to the braking system so that the braking system can continuously determine whether the wheel has the locking fault according to the duration of the locking fault. The problem that the judgment result of the locking fault of the wheel is inaccurate due to misjudgment of a network system can be avoided, and the judgment accuracy of the locking fault of the wheel is further improved.
Based on the wheel locking fault determination method provided by the above method embodiment, the embodiment of the present application further provides a wheel locking fault determination system, which will be described below with reference to the accompanying drawings.
