Detailed Description
The present invention will be described in further detail with reference to specific embodiments.
The invention provides a method for quickly checking LKJ vehicle-mounted data by using sliding screen operation, which is used for checking the written LKJ data or verifying whether the control of an LKJ control program is correct or not after the LKJ control program is modified. Compared with the prior art, the method provided by the invention has the advantages that the data is checked in a screen sliding mode instead of the conventional method of directly checking in a key mode, the acquisition density can be set as required to acquire data points, and the defect of losing control data in the prior art is prevented or reduced.
The invention specifically comprises the following steps:
firstly, LKJ vehicle-mounted data to be checked are graphically displayed on a touch display screen through the existing method, the LKJ vehicle-mounted data to be checked are displayed on the touch display screen from near to far from the current position of a train in a line mode, and graphic marks such as stations, signal lamps, speed limit curves and the like can be displayed on the line.
After LKJ basic data are compiled to form LKJ vehicle-mounted data, the data need to be checked to get on the vehicle, and therefore data correctness is determined. When data is required to be checked, fingers of a checking person drive a map sliding screen to the current position of the train from the target position to which the train moves, pressing is finished, and the fingers are lifted; or the current position of the train drives the train sliding screen to the target position of the train, the pressing action is finished, and the finger is lifted; in the screen sliding process, fingers slide along the train walking line to simulate real walking.
If the map is dragged by fingers in the dragging process, and the train is not moved, the fingers drag the current position of the train from the target position where the train is going to move forwards, namely, the screen is slid along the opposite direction of the train moving route to simulate the train moving, so that the front route data moves backwards along with the moving; if the train is dragged, and the map is still, the fingers slide from the current position of the train to the target position of the train to simulate the running, namely, the screen is slid along the same direction of the running line of the train, so that the line data in front moves back along with the running.
In the process of sliding the screen by the finger, the processor sends a train running position at fixed millisecond intervals to ensure that more train control data cannot be lost. For example, when the train needs to go forward by 2000 meters and directly crosses the middle line to reach 2000 meters, part of the subarea signal machine control data can be lost because the data do not pass through the signal machine, so that the processor collects the train walking position once every set time in the screen sliding process, namely, the record of the forward distance is updated once, and the signal machine control data is not lost as far as possible. After the controller collects data, the controller carries out simulation operation on the locomotive through built-in existing simulation software to obtain state data of the locomotive in the current walking process, and when the locomotive walks to a target position, the data can be displayed, so that a worker can check whether poetry sentences are correct or not.
The controller connected with the touch display screen acquires LKJ vehicle-mounted data information corresponding to a target position stored in a memory connected with the controller according to coordinates of the target position, and displays the LKJ vehicle-mounted data information when the locomotive is simulated to run to the current position on the screen for a checker to check, wherein the LKJ vehicle-mounted data information comprises inherent LKJ basic data information at the position, such as a station, a signal machine, a bridge, a tunnel and the like, and also comprises control information generated by LKJ control software in a calculation mode, such as a speed limit curve, temporary disclosure, side line control information called according to a color light signal and the like.
In the process, the controller records the current position pressed by the finger of a checking person, the lifted target position and the screen sliding line, and calls LKJ vehicle-mounted data to simulate the real running of the train according to the screen sliding line pressed by the finger, namely, when the finger screen sliding simulates the running of a locomotive, the situation that partial function control is incorrect due to a direct fast-forward mode is avoided, and further more correct LKJ control data at the target position can be obtained.
The line data can be verified one meter and one meter, but the verification is very complex, and the current speed of the train is calculated according to a fixed interval in the actual train running process so as to obtain the displacement, so that the method can more truly simulate the real running of the train by calculating the current train distance at a certain time interval.
When the check personnel press the touch screen with fingers and slide the screen along the train walking line:
(1) in a screen sliding line between the pressing and lifting of the finger of the checking personnel each time, starting from an initial pressing position, pressing points are collected along the screen sliding line at set time intervals, the position difference between adjacent pressing points is calculated, and the number of meters corresponding to the position difference is calculated according to the screen resolution.
(2) If the number of meters is within the set range, sending displacement information to the controller, and controlling the train on the touch screen to move to the designated position by the controller; the displacement information is the position difference between two detections, the set meter is a numerical value of the distance which can not lose the control state information, the displacement information is normal when the displacement information does not exceed the numerical value, and the simulation needs to be carried out again if the displacement information does not exceed the numerical value.
(3) And (5) circulating the operations of (1) to (2) until the finger of the checking personnel is detected to be lifted, and then finishing.
(4) And (3) when the fact that the finger of the checking person presses the touch screen is detected again, the operation of (1) - (3) is circulated.
The process changes the collection of each point on the screen in the walking line into the collection of a certain number of pixels at intervals, reduces the collection number, can adjust the interval data according to different test objects, flexibly changes and adapts to various tests.
The present invention can implement all or part of the processes of the above methods, and can also be implemented by using a computer program to instruct related hardware, where the computer program can be stored in a computer-readable storage medium, and when the computer program is executed by a processor, the steps of the above method embodiments can be implemented.
