Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The multi-vehicle operation automatic test system, method, apparatus and storage medium of the present invention are described below with reference to fig. 1-3.
Fig. 1 is a schematic structural diagram of a multi-vehicle operation automatic test system provided by the present invention, as shown in fig. 1, including a train control module 110 and a plurality of simulation test modules 120, wherein:
the train control module 110 is used for outputting train control instructions and train control interaction signals; the train control instruction is used for controlling the running state of the train, and the train control interaction signal is used for indicating the running purpose of the train;
each of the simulation test modules 120 includes a run simulation module and an interactive simulation module, wherein:
The operation simulation module is used for simulating train operation according to the train control instruction output by the train control module;
The interactive simulation module is used for simulating train operation according to the train control interactive signals output by the train control module.
In the embodiment of the present invention, the train control module 110 is a control system for controlling the operation of all vehicles in a multi-vehicle system that needs to perform operation test, for example, a communication-based train operation control system (Communication Based Train Control System, CBTC); the CBTC system may include a plurality of subsystems such as an interlock subsystem, zone control subsystem (ZC), automatic train monitoring subsystem (Automatic Train Supervision, ATS), autopilot subsystem (Automatic Train Operation, ATO), autoguard subsystem (Automatic Train Protection, ATP), etc.; it can be understood that, in the embodiment of the present invention, the train control module 110, especially the interlocking subsystem, the regional control subsystem, and other subsystems for controlling signals of multiple vehicles are test objects of the automatic test system for multiple vehicle operation in the embodiment of the present invention, and the embodiment of the present invention may use the corresponding input/output interface of the train control module to implement the operation control according to the train control module, so that the train control command and the train control interaction signal output by the train control module 110 have the same algorithm and logic as the output of the train control module 110 during the actual operation, so as to implement the automatic test of the multiple vehicle system for rail transit based on simulation, which is close to the actual situation.
In the technical field of rail transit, although the CBTC system can send out most control instructions to realize automatic control of rail vehicles, for some scenes which do not meet automatic driving conditions, in order to ensure rail transit safety, the CBTC system or a platform can only send out corresponding train control interaction signals to indicate the purpose of train operation, but cannot directly control the running state of the train. Thus, embodiments of the present invention provide for the interactive simulation module 120 to simulate the response of a driver to the train control interactive signals, thereby enabling train simulation for different situations.
The scenario related to the embodiment of the invention, in which the autopilot condition is not satisfied, may include: the train is not positioned, the ATO system does not meet the starting condition, the train needs to start the turn-back flow, and the train operation is finished; it can be understood that the above-mentioned scenes cover most of scenes which do not meet the automatic driving condition, and for the scenes which do not meet the automatic driving condition, which are not related to the embodiment of the present invention, the corresponding control logic can also be designed for the simulation test module to realize the simulation of the corresponding scenes.
In the embodiment of the present invention, the automatic test system for multi-vehicle operation may be initialized according to the train operation diagram or the schedule, a simulation test module 120 is constructed for each train in the train operation diagram or the schedule, each simulation test module 120 corresponds to a simulation train, and a process of an ATS system, an ATO system, and an ATP system is started for each simulation test module 120 in the train control module 110.
Therefore, the multi-vehicle operation automatic test system of the embodiment of the invention enables the operation simulation module to simulate the train control instruction output by the train control module by constructing the simulation test module comprising the operation simulation module and the interaction simulation module, and the interaction simulation module simulates the operation of a driver and simulates the train control interaction signal output by the train control module; the running simulation module can simulate the running states of the simulated trains with different running parameters, and the interactive simulation module can simulate the reaction of drivers and control instructions sent to the trains, so that the simulation-based rail transit multi-vehicle system automatic test close to the real situation is realized under the condition of saving manpower and hardware resource allocation.
For a scene where a train is not positioned, in the embodiment of the invention, the train control interaction signal comprises whether the train is positioned or not; the interactive simulation module is used for executing the following steps when the received train control interactive signal indicates that the train is not positioned:
Closing the control of the running simulation module to the simulation train;
controlling the simulated train to run at a low speed until the train is positioned;
and sending the positioning message to a train control module.
The embodiment of the invention simulates the operation steps of a driver in a scene where the train is not positioned through the steps. The low-speed operation of the embodiment of the invention is lower than the normal or preset operation speed of the train; may be operated according to a preset speed. When the train is not positioned in the actual scene, because an automatic driving system is not available, a train driver needs to control the train to run at a safe speed by self and wait for positioning recovery; therefore, the interactive simulation module of the embodiment of the invention simulates the operation so as to realize the simulation of the non-positioned scene of the train.
For a scene that the ATO system does not meet the starting condition, in the embodiment of the invention, the train control interaction signal comprises whether to get off; the interactive simulation module is used for starting the operation simulation module to control the simulation train when the received train control interactive signal indicates the train to be sent; and when the received train control interaction signal indicates that the train is not sent, closing the control of the running simulation module on the simulation train.
The embodiment of the invention simulates the operation steps of a driver in a scene of which the ATO system does not meet the starting condition through the steps. For an ATO system, the ATO can control the movement of the train as long as the condition that the movement authorization condition is met in front of the train is detected; however, in some scenarios, such as trains at a platform without arrival at departure time, or trains need to stay on track for dispatch reasons, where the train is not operational while meeting movement authorization conditions, the driver needs to wait for an indication to start the rail vehicle; therefore, the interactive simulation module of the embodiment of the invention simulates the operation so as to realize the simulation of the scene that the ATO system does not meet the starting condition.
For a scene that a train needs to start a turn-back flow, in the embodiment of the invention, a train control interaction signal comprises whether to enter the turn-back, and when the received train control interaction signal indicates to enter the turn-back, the interactive simulation module executes the following steps:
Acquiring simulated train operation information according to a train control module;
Determining first information according to the simulated train operation information, wherein the first information is used for indicating whether to confirm turning back or not; when the first information indicates the train to turn back, the first information is sent to a train control module;
Determining second information according to the simulated train operation information, wherein the second information is used for indicating the turning-back flow to end;
the train control module is used for executing the following steps when the received first information indicates confirmation of turning back:
Generating a train turn-back control instruction according to the simulated train operation information;
and sending the train turn-back control instruction to an operation simulation module.
The embodiment of the invention simulates the operation steps of a driver in a scene needing to start the turn-back flow through the steps. When a rail vehicle runs, manual control of turning back is required at certain stations or rails, and the flow is generally as follows: the driver receives the turn-back indication, controls the running direction of the train to realize turn-back at a proper track section, and reports turn-back completion information; in the embodiment of the invention, the interactive simulation module can determine the turning-back time of the rail train and report the turning-back time to the train control module; because the running process of the train after turning back meets the automatic driving condition, after the train control module receives the first information, a control instruction after turning back can be generated and sent to the running simulation module to control the running state of the simulated train after turning back; after the turning-back is completed, the interactive simulation module reports turning-back completion information. In the embodiment of the invention, whether the turning-back is finished can be judged according to the positioning and running states of the simulated train, for example, when the simulated train is in a preset turning-back station and needs to be turned back, the turning-back can be judged to be finished when the simulated train returns to the turning-back station again and stops running; the foldback for other cases is similar; therefore, the interactive simulation module of the embodiment of the invention simulates the operation so as to realize the simulation of the scene of the turn-back flow to be started.
For the scenario of ending the train operation, in the embodiment of the present invention, the interactive simulation module is further configured to execute the following steps:
acquiring a simulation test running chart according to the train control module;
And judging whether the simulation test is finished or not according to the simulation test running diagram.
It can be appreciated that when the simulation test of a single simulated train is completed, the computing resources corresponding to the simulated train can be released from the computing device, so as to improve the efficiency of the simulation calculation. Specifically, according to the simulation test running diagram, the interactive simulation module judges that the simulation train has reached the last station, considers that the simulation train has completed the simulation test, releases the calculation resources of the simulation train, and informs the train control module of the process of destroying the ATS system, the ATO system and the ATP system corresponding to the simulation train.
In the embodiment of the invention, the multi-vehicle running automatic test system can comprise a man-machine interaction module which is in communication connection with the train control module so as to realize the monitoring and control of train control instructions and train control interaction signals output by the train control module, so as to simulate different emergency situations and change test conditions.
In the embodiment of the invention, the interactive simulation module can acquire the running state information of the simulated train, such as speed information, acceleration information, pose information, destination information and map information, according to the train control module so as to make a train control decision, so that the simulation of the interactive simulation module on the scene which does not meet the automatic driving condition is closer to the actual situation.
In summary, the multi-vehicle operation automatic test system of the embodiment of the invention constructs the simulation test module comprising the operation simulation module and the interaction simulation module, so that the operation simulation module simulates the train control instruction output by the train control module, and the interaction simulation module simulates the operation of a driver and simulates the train control interaction signal output by the train control module; the running simulation module can simulate the running states of the simulated trains with different running parameters, and the interactive simulation module can simulate the reaction of drivers and control instructions sent to the trains, so that the simulation-based rail transit multi-vehicle system automatic test close to the real situation is realized under the condition of saving manpower and hardware resource allocation.
