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.
As shown in fig. 1, the railway driving early warning method provided by the invention comprises the following steps:
step 101: acquiring a first railway line of a railway driving to early-warning terminal equipment and a second railway line where the early-warning terminal equipment is located;
in the step, firstly, the railway driving to the early warning terminal equipment is determined, then the first railway line where the railway driving is currently located is determined based on the driving information reported by the railway driving at fixed time, and the second railway line where the early warning terminal equipment is located is obtained.

In the step, according to the position information of the line switching point, a first distance between the railway running to the early warning terminal device and the line switching point is determined, and a second distance between the early warning terminal device and the line switching point is determined. And finally, calculating the actual railway distance between the railway running to the early warning terminal equipment and the early warning terminal equipment according to the first distance and the second distance. The railway driving early warning system can set an early warning distance according to the actual running condition of the terminal equipment, when the actual railway distance between the railway driving and the early warning terminal equipment is smaller than or equal to the early warning distance of the early warning terminal equipment, the railway driving approaching early warning information is sent to the early warning terminal equipment, and when the actual railway distance between the railway driving and the early warning terminal equipment is larger than the early warning distance of the early warning terminal equipment, the railway driving approaching early warning information is not sent to the early warning terminal equipment.
The railway driving early warning method provided by the invention comprises the steps of firstly obtaining a first railway line of a railway driving to early warning terminal equipment and a second railway line where the early warning terminal equipment is located, then determining a line switching point for switching the railway driving to the early warning terminal equipment to the railway line where the early warning terminal equipment is located according to the first railway line and the second railway line, so that according to the line switching point, calculating the actual railway distance between the railway driving to the early warning terminal equipment and the early warning terminal equipment, and sending the railway driving approaching early warning information to the early warning terminal equipment when the actual railway distance is smaller than or equal to the early warning distance of the early warning terminal equipment. Therefore, when the railway vehicle and the terminal equipment are not on the same railway line, the invention firstly determines the railway vehicle which drives to the early warning terminal equipment to be switched to the line switching point of the railway line where the early warning terminal equipment is located, then respectively determines the distance between the railway vehicle and the line switching point and the distance between the terminal equipment and the line switching point based on the position information of the line switching point, and further obtains the actual distance between the railway vehicle and the terminal equipment on the railway by utilizing the mode of distance summation. According to the method and the device, the railway driving approaching early warning is carried out according to the calculated actual railway distance between the railway driving to the early warning terminal device and the early warning terminal device, and compared with the existing longitude and latitude calculation mode, the actual distance between the railway driving to the early warning terminal device and the early warning terminal device on a railway can be calculated more accurately, so that the accuracy of railway driving early warning is improved, and early warning errors are avoided. In addition, compared with the existing radio station early warning mode, when the railway vehicle approaches the terminal equipment after multiple line turns, the method can accurately early warn through the actual distance between the railway vehicle and the early warning terminal equipment on the railway, and the defect that whether the terminal equipment is early warned or not cannot be judged due to multiple line turns of the railway vehicle is avoided.
Based on the foregoing embodiment, in this embodiment, calculating, according to the line switching point, an actual railway distance between a railway driving to the early warning terminal device and the early warning terminal device includes:
determining a first distance between a railway travelling crane which drives to the early warning terminal equipment and the line switching point and a second distance between the early warning terminal equipment and the line switching point according to the position information of the line switching point;
and calculating the actual railway distance between the railway running to the early warning terminal equipment and the early warning terminal equipment according to the first distance and the second distance.
In this embodiment, it should be noted that, in the discussion of calculating the actual railway distance between the railway vehicle and the early warning terminal device, the first case is that the railway vehicle approaches the early warning terminal device on the line where the early warning terminal device is located, and at this time, the distance between the railway vehicle that is driven to the early warning terminal device and the early warning terminal device may be calculated according to the position information of the railway vehicle that is driven to the early warning terminal device and the position information of the early warning terminal device. For example, the distance between the railway driving to the early warning terminal device and the early warning terminal device is calculated according to the kilometer post of the railway driving and the kilometer post of the early warning terminal device. The other condition is that the railway train is currently driven to the railway line where the early warning terminal equipment is located on other railway lines, and at the moment, the railway train is firstly determined to be switched to the line switching point of the railway line where the early warning terminal equipment is located. Specifically, a line switching point is determined according to the information of the railway line where the railway driving is currently located and the information of the railway line where the early warning terminal equipment is located. After the line switching point is determined, the distance between the railway vehicle and the line switching point, which are driven to the early warning terminal equipment, can be determined according to the position information of the line switching point, and the distance between the line switching point and the early warning terminal equipment can be determined, and the actual railway distance between the railway vehicle and the early warning terminal equipment can be obtained by adding the two distances. Compared with the existing longitude and latitude calculation mode, the method can calculate the actual distance between the railway running to the early warning terminal device and the railway on which the early warning terminal device is located more accurately, so that the accuracy of early warning of the railway running is improved, and early warning errors are avoided. In addition, compared with the existing radio station early warning mode, when the railway vehicle approaches the terminal equipment after multiple line turns, the method can accurately early warn through the actual distance between the railway vehicle and the early warning terminal equipment on the railway, and the defect that whether the terminal equipment is early warned or not cannot be judged due to multiple line turns of the railway vehicle is avoided.
Based on the content of the above embodiment, in this embodiment, further includes:
determining a railway line set which is required to be switched from the railway driving to the early warning terminal equipment to the railway line where the early warning terminal equipment is located according to the line information of the first railway line and the line information of the second railway line;
sequentially determining the line switching points of two adjacent railway lines in the railway line set according to the line switching sequence of railway travelling to the early warning terminal equipment to obtain a line switching point set;
determining a third distance between a railway travelling crane which drives to the early warning terminal equipment and a line switching point of a railway line where the early warning terminal equipment is located according to the position information of each line switching point in the line switching point set, and determining a second distance between the early warning terminal equipment and the line switching point; and calculating the actual railway distance between the railway running to the early warning terminal equipment and the early warning terminal equipment according to the third distance and the second distance.
In this embodiment, it should be noted that, when the railway vehicle needs to make a plurality of turns to drive into the railway line where the early warning terminal device is located, it is necessary to first determine a set of railway lines where the railway vehicle needs to be switched before switching to the railway line where the early warning terminal device is located, then sequentially determine line switching points of two adjacent railway lines according to a line switching sequence of the railway vehicle driving to the early warning terminal device, obtain a set of line switching points, determine a distance between the railway vehicle driving to the early warning terminal device and the line switching point of the railway line where the early warning terminal device is located according to position information of each line switching point in the set of line switching points, and determine a distance between the line switching point and the early warning terminal device. And finally, carrying out addition operation on the two distances to obtain the actual railway distance between the railway running and the early warning terminal equipment. For example, the current line of the railway vehicle is S1, the line of the railway vehicle entering the early warning terminal device needs to be sequentially switched from the line S1 to the line S2, then from the line S2 to the line S3, and finally from the line S3 to the line S4 of the early warning terminal device, then the set of railway lines to be switched by the railway vehicle is { S1, S2, S3, S4}, further, the line switching points of two adjacent railway lines are sequentially determined, for example, the switching points a of S1 and S2, the switching points B of S2 and S3, and the switching point C of S3 and S4 are determined, and then the set of line switching points is { a, B, C }. According to the A, B, C position information, the actual railway distance from A to C can be calculated, the actual railway distance from A to C and the actual railway distance from the early warning terminal equipment to C are calculated, and the actual railway distance from A to C, the actual railway distance from A to C and the actual railway distance from the early warning terminal equipment to C are added to obtain the actual railway distance from the railway to the early warning terminal equipment. Therefore, the method is suitable for the condition that the railway vehicle reaches the early warning terminal equipment after being subjected to line changing for many times, and can accurately calculate the actual railway distance between the railway vehicle and the early warning terminal equipment, so that the early warning is performed, and the method has strong practicability.
Based on the above-mentioned embodiments, in this embodiment, according to the actual railway distance and the running speed of the railway running to the early-warning terminal device, the estimated time for the railway running to the early-warning terminal device to reach the position where the early-warning terminal device is located is calculated, and the estimated time is sent to the early-warning terminal device.
In this embodiment, optionally, after the actual railway distance between the railway vehicle and the early warning terminal device is calculated, the estimated time for the railway vehicle traveling to reach the early warning terminal device may be calculated according to the current traveling speed reported by the railway vehicle, and the estimated time may be sent to the early warning terminal device, so as to remind related personnel to stop the current operation and execute the coping operation.
Based on the content of the above embodiment, in this embodiment, further includes:
determining each railway line connected with the early warning terminal equipment according to the position information of the early warning terminal equipment;
and determining railway driving to the early warning terminal equipment on each railway line connected with the early warning terminal equipment according to the driving information reported by each railway driving at fixed time.
In this embodiment, it should be noted that, due to the crisscross railway lines, there may be multiple line switching points in the current railway line where the early warning terminal device is located, that is, there may be a case where other multiple railway lines are incorporated into the current railway line. In order to accurately calculate the actual railway distance between the railway running and the terminal equipment, the method firstly acquires the position information of the early warning terminal equipment, and then determines each railway line connected with the early warning terminal equipment according to the position information of the terminal equipment. The position information of the early warning terminal device may include one or more of a railway line code where the early warning terminal device is located, a kilometer sign of a railway line where the early warning terminal device is located, and a longitude and latitude of the early warning terminal device, where the longitude and latitude of the early warning terminal device may be converted into a corresponding line code and a corresponding kilometer sign, which are not described herein. The terminal device according to the present invention may be a device providing voice and/or data connectivity, a handheld device having a wireless connection function, or other processing device connected to a wireless modem, etc. The names of the terminal devices may also differ in different systems, and the wireless terminal devices may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g. portable, pocket, hand-held, computer-built-in or car-mounted mobile devices, which exchange speech and/or data with the radio access network.
In this embodiment, it should be noted that, the existing longitude and latitude calculation method and the wireless radar calculation method cannot determine whether the railway vehicle will drive to the terminal device, so that false alarm is easily caused, and normal construction operation of the terminal device is affected. Therefore, in the step, through the running information of each railway running on the railway line, which is reported at fixed time, the railway running to the early warning terminal equipment is determined on each railway connected with the early warning terminal equipment, the non-approaching railway running away from the terminal equipment is removed, the subsequent calculated amount is reduced, and the early warning efficiency of the railway running is improved. The running information reported by the railway running can comprise one or more of the position information, the running speed and the running direction of the railway running, the position information of the railway running can comprise one or more of the railway line code of the railway running, the kilometer sign of the railway line of the railway running and the longitude and latitude of the railway running, and the longitude and latitude of the railway running can be converted into the corresponding line code and the corresponding kilometer sign.
Based on the foregoing embodiment, in this embodiment, the determining, according to the location information of the early warning terminal device, each railway line connected to the early warning terminal device includes:
Acquiring a railway line code of the early warning terminal equipment;
and determining each railway line connected with the early warning terminal equipment according to the railway line code.
In this embodiment, optionally, each railway line connected to the early-warning terminal device may be determined according to the railway line code where the early-warning terminal device is located, and the early-warning trend of the early-warning terminal device may be determined according to the railway line code where the early-warning terminal device is located and the kilometer scale of the early-warning terminal device, for example, L1 and L2 in fig. 8 are early-warning trends of the early-warning terminal device, the kilometer scale of the early-warning terminal device is k50+0000 kilometers, the early-warning trend of the railway line where the early-warning terminal device is located is k65+000 kilometer-k50+0000 kilometer-k35+000 kilometers, and further, other railway lines incorporated into the railway line where the early-warning terminal device is located are determined within the range of the early-warning trend is k65+000 kilometer-k50+0000-k35+000 kilometer, for example, the railway line corresponding to the early-warning trend L3 in fig. 9. In this embodiment, each railway line connected to the early warning terminal device is determined, so as to more accurately obtain the railway driving approaching the early warning terminal device, and not only for the railway driving on which the early warning terminal device is located, thereby expanding the early warning analysis range.
Based on the foregoing embodiment, in this embodiment, determining, according to the travel information reported at regular time of each railway travel, a railway travel to the early-warning terminal device on each railway line connected to the early-warning terminal device includes:
determining the railway running normally running on each railway line connected with the early warning terminal equipment according to the running information reported by each railway running at regular time;
and determining the railway running to the early warning terminal equipment according to the running direction of the railway running normally running on each railway line connected with the early warning terminal equipment. In this embodiment, it may be determined, according to the running direction in the running information reported by the railway vehicle, whether the railway vehicle is currently moving near the early warning terminal device or moving away from the early warning terminal device, so as to select the railway vehicle near the early warning terminal device to perform subsequent distance calculation, and reject the railway vehicle away from the early warning terminal device, thereby achieving the effect of reducing the calculation amount.
