In this embodiment, only when the simulation simulator IS in an operating state, an instruction for starting recording may be sent to the simulation simulator through a control window of the trainer station, and the IS control window starts the starting recording including the following operations: and adding the record item in the IS list, hiding the history record information, and adding an initial scene node under the record item, wherein the playback function related buttons are not available at the moment, and displaying a data record in a state pane of the simulation simulator.
When the simulation simulator IS in an operating state, each simulation system HMI and a corresponding simulation logic scheduling service response instruction carry out data simulation, at the moment, after a simulation data service module receives a start record command sent by an IS, a data point to be recorded at this time IS obtained from a record data point list (record_points) of a MYSQL database, a simulation system data obtaining API IS automatically called according to configuration frequency, real-time values of the record_points data point are obtained from a real-time shared memory and stored into a time sequence database INFLUXDB, wherein the configuration frequency IS preset in a starting configuration file of the simulation data service module.
In the process of data recording, if a user judges that certain scenes are needed to be particularly focused or studied with great importance, the user can also send out instructions for saving the scenes from the coach station so as to add corresponding labels to the current data recording according to actual requirements,
during data recording, the simulation data service module samples and stores all data point values in the recorded data point list according to the instruction, and although the data points are screened relative to the actual measuring points, the data quantity stored after each recording is relatively large, so in the embodiment, the scene is synchronously saved in the process of data recording, and in the subsequent data playback, a user can quickly find the data to be played back from the data recording according to the scene information. In addition, the node description may be modified in the IS control window to further facilitate locating at playback.
The scene preservation method specifically comprises the following steps: when the user IS in the data recording process, sending a scene saving command at the IS control window, adding a new scene child node under a record item displayed in the IS control window, displaying action triggering time in node information, and correspondingly generating scene information in a scene list of the MYSQL database; if the user sends out a plurality of scene saving commands in the IS control window in the data recording process, the scene list correspondingly generates a plurality of scene information;

The data recording operation can complete the process of one time of data recording, after the data recording IS completed, the first-level node of the list displays the recorded item information (data points) in the control window of the IS, and the second-level node displays the scene list stored in the current record. At this time, if data playback IS required, interaction between the IS and the simulation simulator IS required first, so that the simulation simulator enters a frozen state.
When the simulation simulator IS in a frozen state, a user can click a start button in a playback column in a control window of an IS to generate a start playback command, after receiving a start playback command sent by the IS, a simulation data service module analyzes a corresponding control word, obtains a start point and an end point of the current playback time, reads historical data from INFLUXDB according to a default frequency, writes the historical data into a real-time shared memory, and a simulation system HMI reads the historical data from INFLUXDB and writes the historical data into the real-time shared memory, so that the simulation system HMI refreshes a picture according to a historical record to play data, wherein the default frequency can be set in the IS control window according to user requirements.

Preferably, the data playback further includes an operation of setting a playback speed, and the first type of control instruction further includes a playback speed setting instruction, and the user can modify the default frequency in the process of data playback in addition to setting the default frequency in the generation of the start playback command, and after the user modifies the default frequency to generate the instruction of setting the playback speed, the simulation data service module obtains data from the INFLUXDB according to the newly received playback speed parameter at a multiplying power time interval, so that a fast forward effect of fast playback of the historical data is seen on a flowchart of the simulation system HMI.
Preferably, the data playback further includes an operation of suspending playback, and the corresponding first type of control instruction further includes a playback suspension instruction, when the simulation data service module receives the playback suspension instruction during the data playback, the simulation data service module stops the operations of acquiring data from the time sequence database and writing into the shared memory.
Specifically, after the IS control window issues a playback start command, the "pause" and "stop" buttons in the control window are available, and the list only presents the record and sub-scene nodes to which the scene belongs, and the simulator status pane displays "data playback". The simulator status pane "data disappear". In addition, when the playback start instruction is sent, the rate frequency of the playback can be input in the control window, for example, the playing rate is set to be 5 times, so that fast forward playing can be performed according to the speed required by the user. After receiving a playback command sent by the IS, the simulation data service module acquires data from the INFLUXDB according to the multiplying power time interval, so that the fast forward effect of fast playback of the historical data IS seen on the flow chart of the simulation system HMI, and 20 times fast forward IS supported at maximum.
Meanwhile, in the data playback process, if the progress bar is dragged in the right lower corner of the control window, the simulator time can be seen to jump to the dragging point, at this time, the simulation data service module acquires the current position time point, changes the data acquisition starting point, and reads the historical data from the INFLUXDB. The simulator time displayed by the simulator IS starts from the recording start point, IS refreshed, and IS played back until the scene time point.
