The first flow Cheng Quxiao indicates that flow nodes in the first flow that did not execute the completion do not continue to execute, and that the data or state associated with each flow node is restored to a normal state. The normal state refers to a default state of the respective data or states.
The method for judging whether the compensation task node is successfully executed according to the execution result can be as follows: and acquiring the state change condition of the compensation task node.
Optionally, the execution result of each flow node is stored in a database by the workflow engine. After the preset time, determining whether the execution result of the corresponding flow node is stored in the database.

The execution order of each flow node of the first flow and the data or equipment and the like in which interaction is required are determined based on the node attributes.
The first flow is assumed to be a flow for guiding the vehicle to stop. When the vehicle arrives at the hall door, the ground sensing signal is triggered. And triggering an execution request of a first process while receiving the ground sensing signal, wherein the first process needs to open the hall door, guide the vehicle to stop, detect that the vehicle enters the hall and close the hall door.
The node attribute represents the type of task that each flow node needs to perform and the data that needs to be given or obtained to perform the task. For example, the process node of opening the outer door of the car hall needs to acquire the state of the outer door of the car hall, if the outer door of the car hall is in a closed state, the outer door of the car hall needs to be controlled to be opened, and finally, the opened result of the outer door of the car hall is returned.
After the execution is completed, the door outside the car hall is opened, the car is stopped and guided, whether the car enters the car hall or not is detected, when the execution state returned by the flow node is not received for more than the preset time, the flow node can be determined not to be executed, and the working state of the first flow is confirmed to be an abnormal state.
In this embodiment, by receiving the execution state returned by the first flow, if the execution state returned by the first flow is not received after the preset time elapses, the working state of the first flow is confirmed to be an abnormal state, and when the first flow is in the abnormal state, the subsequent flow cannot be executed, and the first flow needs to be cancelled, which is beneficial to the execution of the subsequent flow.
Further, S100, if the working state of the first flow is an abnormal state, obtaining, by the workflow engine, the second flow based on the node information of the first flow includes:
s130, acquiring the compensation flow configuration information of the first flow through a workflow engine.
S140, if the compensation flow configuration information indicates that the first flow is provided with the compensation flow, the compensation flow is obtained as the second flow.
Specifically, the workflow engine configures information by accessing the compensation flow of the first flow in the database. The compensation flow configuration information indicates whether the first flow is provided with a compensation flow, and the compensation flow is used for restoring data or equipment involved in the first flow to a normal state when the first flow is canceled.
The compensation flow can be created by a workflow engine, after the creation is successful, the flow information of the whole compensation flow is stored in a database, and the state of the compensation flow configuration information is configured as available. When the first flow needs to be canceled, the compensation flow is acquired as a second flow by the workflow engine.
In this embodiment, compensation flow configuration information of the first flow is obtained, where the compensation flow configuration information is used to obtain a compensation flow of the first flow, and according to the compensation flow, a task can be reset when the first flow is suddenly interrupted, so as to reset data or equipment involved in the first flow.
Further, S130, obtaining, by the workflow engine, compensation flow configuration information of the first flow includes:
s131, if the compensation flow configuration information indicates that the first flow is not configured with the compensation flow, the node index of the first flow is obtained.
S132, based on the node index, inquiring a second flow with an index relation with the first flow in the workflow engine.
Specifically, if the compensation flow configuration information of the first flow indicates that the first flow does not configure the compensation flow, a second flow having an index relationship with the first flow is obtained according to the node index of the first flow.
The second flow may be composed of a plurality of flow nodes having an index relationship with the flow nodes in the first flow.
In addition, a node index is used to indicate associations between the various flow nodes. Firstly, establishing node indexes according to the flow information of each flow node, and establishing an index relation with a preset sequence of the flow nodes with the index relation.
For example, node a and node B store an association in execution order. In another flow, node A has an association with node C in order of execution, and then node A's node index includes node B and node C.
Specifically, the node index of the flow node includes different node attributes of the flow node, and the flow task corresponding to each node attribute is different.
The first flow includes a node A, and other flow nodes are obtained according to the node index of the node A. It should be noted that, if the node index includes a plurality of flow nodes, the corresponding flow nodes are matched according to the task information of the first flow. And acquiring a second flow with an index relation with the first flow according to the node attribute of the flow node in the first flow and the node index, wherein the second flow consists of a plurality of flow nodes with an index relation with the flow node of the first flow.
Specifically, the node index of the first flow is created by the workflow engine, an index relationship is constructed according to the node representations of the nodes of each flow, and the index relationship is stored in the database. And inquiring the index relation of the first process in the database through the workflow engine to obtain a second process with the index relation with the first process.
Optionally, node indexes of the flow nodes are stored in the form of building node trees, and a second flow with an index relation with the first flow is obtained by inquiring the index relation of the tree nodes.
In this embodiment, a second flow having an index relationship with the first flow is obtained through the node index of the first flow, and the second flow is beneficial to the subsequent construction of the compensation flow.

Specifically, the process node of the last return of the execution result of the first process refers to the process node that is executed last when the working state of the first process changes to the abnormal state.
For example, the first procedure needs to complete the parking process of the user, firstly, the vehicle arrives at the hall door, the ground sensing signal is triggered, the hall outer door is controlled to be opened, the display screen is controlled to display information for guiding the user how to park, the vehicle enters the hall, and the hall outer door is closed after parking is completed.
The user cannot park due to temporary something or other, because the result of the vehicle entering the hall and parking is not received, and the hall door is always in an open state.
The hall door is always in an open state, which creates a safety hazard and requires the hall door to be closed before the first procedure is canceled.
After the last time of the process node which returns the execution result is obtained, a compensation task node is created according to the next execution task node of the process node, and the execution result of the compensation task node is monitored.
As an alternative implementation manner, the judging process is set based on the task result by acquiring the task result of the first process, and whether the compensation task node is successfully executed is determined by the execution result of the judging process.
For example, the task result of the first procedure corresponds to the closing of the hall door, and the compensation task node needs to perform an action of closing the hall door, and then determines whether the hall door has been closed by the determination node based on whether the hall door is closed or not.
In this embodiment, the execution details of the first flow are acquired based on the workflow engine to create the compensation task node, and the execution state of the compensation task node is determined by monitoring the execution result of the compensation task node, so that the first flow can be smoothly canceled, the subsequent flow can be ensured to be executed, and the execution effect of the flow is improved.
Further, S300 is configured to determine whether the execution of the compensation task node is successful according to the execution result, and cancel the first flow through the workflow engine if the execution of the compensation task node is successful, including:
s310, acquiring a flow update state corresponding to the compensation task node from the execution result, wherein the flow update state comprises a state change label of the compensation task node.
S320, if the state change label indicates that the compensation task node is successfully executed, the first flow is canceled through the workflow engine.
Specifically, a flow update state corresponding to the compensation task node is obtained from the execution result, the flow update state includes a state change label of the compensation task node, if the state change label is 1, it is indicated that the compensation task node is successfully executed, and the first flow can be cancelled.
The first procedure is, for example, opening the hall door, guiding the vehicle to stop, detecting that the vehicle has entered the hall, closing the hall door.
The second flow is to detect the state of the outer door of the car hall, and when the outer door of the car hall is in an open state, the outer door of the car hall is controlled to be closed. The compensation task node may be configured to control the closing of the hall door, return an execution result when the hall door is closed, and record a state change flag.
In this embodiment, the process update state of the compensation task node is obtained, and whether the first process is to be cancelled is determined according to the process update state, so that the first process is ensured not to occupy the execution process of other processes after the first process is cancelled, and meanwhile, after the first process is cancelled, the equipment or data involved in the first process can be restored to the normal state, so that the subsequent process can be ensured to be normally executed, and the execution efficiency of the process task is improved.
Further, after S300, the method further includes:
s400, if the compensation task node is not successfully executed, acquiring detailed flow information corresponding to the compensation task node, wherein the detailed flow information is used for indicating the task information of the compensation task node.

Specifically, if the compensation task node is not successfully executed, acquiring detailed flow information corresponding to the compensation task node, and generating reminding information based on the detailed flow information and an execution result of the compensation task node.
For example, the detailed information of the flow of the compensation task node is to control the door outside the car hall to be closed, and if the execution is not successful, a reminding message that the door outside the car hall is not closed can be generated.
The reminding information can be used for reminding a manager to manually close the hall outer door, so that potential safety hazards are prevented.
In this embodiment, if the compensation task node is not successfully executed, the reminding information is generated based on the detailed flow information of the compensation task node, so as to play a role in reminding.
