Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention discloses a punctual arrival control method for a locomotive, including:
step S11: determining the current speed of a target locomotive and the target distance between the current position of the target locomotive and a target station;
in this embodiment, to achieve punctual arrival of the target locomotive, a current speed of the target locomotive and a target distance of a current location of the target locomotive from the target station are first determined. In practical applications, there are various methods for obtaining the current speed of the target locomotive and the distance between the current position of the target locomotive and the target station, such as: the current speed of the target locomotive may be acquired by a speed sensor or a speed detection device, the current location of the target locomotive may be acquired by a GPS navigator or a location measuring instrument, and then the target distance from the current location of the target locomotive to the target site may be measured by a distance sensor or a distance measuring instrument. Of course, in practical application, the current speed of the target locomotive, the current position of the target locomotive, and the target distance from the current position of the target locomotive to the target station are obtained in any manner, and the embodiment is not limited in particular.
In this embodiment, the target station refers to a station that the target locomotive needs to reach, and may be a station next to the target locomotive on the target locomotive operation route, or a station pre-designated on the target locomotive operation route. In addition, the target locomotive in this embodiment may be a freight locomotive, a passenger train, a motor train unit, or another vehicle type related to punctual arrival, and this embodiment does not specifically limit the vehicle type of the target locomotive.
Step S12: acquiring a target arrival time of a target locomotive to a target station;
after the current speed of the target locomotive, the current position of the target locomotive and the target distance between the current position of the target locomotive and the target station are determined, the target arrival time at which the target locomotive needs to arrive at the target station is also required to be obtained, that is, the purpose of the step is to determine at which time the target locomotive needs to specifically arrive at the target station.
It should be noted that, in this embodiment, the target arrival time may be a standard arrival time on the operation schedule of the target locomotive, or may be a preset arrival time preset by an operator according to the actual requirement, where the setting manner of the target arrival time is not specifically limited.
Step S13: and adjusting the current speed of the target locomotive according to the target distance and the target arrival time so that the target locomotive arrives at the target station at the target arrival time.
It can be understood that, after the target distance between the current position of the target locomotive and the target station is obtained and the target arrival time at which the target locomotive needs to arrive at the target station is obtained, it is equivalent to obtaining the travel relationship between the current position of the target locomotive and the target station, and then the current speed of the target locomotive can be dynamically adjusted according to the travel relationship, so that the target locomotive can arrive at the target station at the target arrival time.
It is conceivable that the current speed of the target locomotive may be adjusted at a constant speed or may be adjusted at a non-constant speed. Here, the process of adjusting the speed of the target locomotive is not particularly limited as long as the target locomotive can reach the target station at the target arrival time.
It is understood that in the present embodiment, the target arrival time of the target locomotive at the target station is used as the output of the closed-loop system, and the target arrival time is fed back to the input of the closed-loop system in a certain feedback manner to dynamically adjust the current speed of the target locomotive, so that the target locomotive can arrive at the target station at the target arrival time. In this way, the accuracy of the target locomotive reaching the target station at the target arrival time can be further improved.
In addition, in the process of adjusting the current speed of the target locomotive, the traction of the target locomotive in the operation process is changed, that is, the target locomotive calculates the traction of the target locomotive according to the factors such as self load, cargo load, motor characteristics of the target locomotive, and the like, and the calculation process is well known by those skilled in the art and will not be described in detail herein.
As can be seen, in this embodiment, the current speed of the target locomotive and the target distance from the current position of the target locomotive to the target station are determined first, and then the target arrival time at which the target locomotive needs to reach the target station is obtained. After acquiring the current speed of the target locomotive, the target distance from the current position of the target locomotive to the target station and the target arrival time when the target locomotive needs to arrive at the target station, it is equivalent to acquiring the distance-travel relationship when the target locomotive arrives at the target station, and finally, adjusting the current speed of the target locomotive in real time according to the acquired distance-travel relationship, so that the target locomotive arrives at the target station at the target arrival time. Obviously, compared with the prior art, the method in the embodiment can objectively adjust the current speed of the target locomotive according to the current running state of the target locomotive, and avoids interference of human subjective factors, so that the method in the embodiment can more accurately realize on-time arrival of the target locomotive.
Referring to fig. 2, another punctual arrival control method for a locomotive is disclosed in an embodiment of the present invention, and the method includes:
step S21: determining the current speed of a target locomotive and the target distance between the current position of the target locomotive and a target station;
step S21 is the same as step S11, and the related description information can refer to step S11, which is not described herein again.
Step S22: acquiring standard arrival time of a target locomotive to a target station;
wherein the standard arrival time is the arrival time on the operation schedule of the target locomotive.
The purpose of this step is to illustrate that, in this embodiment, the target locomotive is controlled on time to the station according to the standard arrival time on the target locomotive operation schedule. It can be understood that if the target locomotive can reach the target station according to the standard arrival time on the operation schedule, the execution sequence of the dispatching system of the target locomotive can be more ordered and reasonable, thereby ensuring the safety and the orderliness of the target locomotive reaching the target station.
Step S23: and if the target locomotive arrives at the target station before the standard arrival time according to the current speed and the target distance of the target locomotive, decelerating the current speed of the target locomotive so as to enable the target locomotive to arrive at the target station at the standard arrival time.
It will be appreciated that the target locomotive may encounter a wide variety of conditions during actual operation. Steps S23 to S25 list the specific situations of the three target locomotives during actual operation.
The purpose of step S23 is to illustrate that if it is determined that the target locomotive can reach the target site before the standard arrival time based on the current speed of the target locomotive and the target distance from the current position of the target locomotive to the target site, in this case, in order for the target locomotive to reach the target site at the standard arrival time, the current speed of the target locomotive may be decelerated so that the target locomotive reaches the target site at the standard arrival time.
If the target locomotive is in such an operating condition, the mode may be referred to as a "creep mode" of the target locomotive. Specifically, if the target locomotive is in the "slow moving mode", in order to enable the target locomotive to arrive at the target station on time, at this time, a specific arrival time at which the target locomotive can arrive at the target station may be calculated according to a current speed of the target locomotive and a target distance between a current position of the target locomotive and the target station, then a slow moving time score of the target locomotive is obtained according to the calculated specific arrival time and a standard arrival time, and finally, the running time at which the target locomotive arrives at the target station from the current position is obtained by adding the slow moving time score to the specific arrival time, and the traction force of the target locomotive is recalculated to decelerate the current speed of the target locomotive, so that the target locomotive can arrive at the target station at the standard arrival time.
Step S24: and if the target locomotive arrives at the target station after the standard arrival time is judged according to the current speed and the target distance of the target train, accelerating the current speed of the target train so as to enable the target locomotive to arrive at the target station at the standard arrival time.
The purpose of step S24 is to illustrate that if it is determined that the target locomotive is not able to reach the target site after the standard arrival time based on the current speed of the target locomotive and the target distance of the current position of the target locomotive from the target site. At this time, in order that the target locomotive does not have a delay in reaching the target station, the current speed of the target train may be accelerated so that the target locomotive can reach the target station at the standard arrival time.
If the target locomotive is in such an operating state, the mode may be referred to as a "drive-up mode" of the target locomotive. Specifically, if the target locomotive is in the "arrival point mode", in order to enable the target locomotive to arrive at the target station on time, at this time, a specific arrival time at which the target locomotive can arrive at the target station may be calculated first, then, an arrival point time division of the target locomotive is obtained according to the calculated specific arrival time, and finally, the arrival point time division is subtracted from the specific arrival time division to obtain a running time at which the target locomotive arrives at the target station from the current position, and the tractive force of the target locomotive is recalculated to accelerate the current speed of the target locomotive, so that the target locomotive can arrive at the target station at the standard arrival time.
Step S25: and if the target locomotive can reach the target station at the standard arrival time according to the current speed and the target distance of the target train, controlling the current speed of the target locomotive to be kept unchanged so as to enable the target locomotive to reach the target station at the standard arrival time.
The purpose of step S25 is to illustrate that, if it is determined that the target locomotive can reach the target site at the standard arrival time according to the current speed of the target locomotive and the target distance between the current position of the target locomotive and the target site, the current speed of the target locomotive is controlled to remain unchanged so that the target locomotive reaches the target site at the standard arrival time.
If the target locomotive is in such an operating state, the mode may be referred to as a "peer-to-peer mode" of the target locomotive, that is, the target locomotive pre-plans the tractive force of the target locomotive and the traveling speed of the target locomotive according to the standard arrival time, so that the target locomotive arrives at the target station at the standard arrival time.
In summary, the present embodiment provides some specific methods for adjusting the current speed of the target locomotive according to the situation encountered by the target locomotive during the actual operation process, and the method can ensure the reliability and accuracy that the target locomotive can reach the target station at the target arrival time.
Referring to fig. 3, another punctual arrival control method for a locomotive is disclosed in an embodiment of the present invention, the method includes:
step S31: determining the current speed of a target locomotive and the target distance between the current position of the target locomotive and a target station;
step S31 is the same as step S11, and the related description information can refer to step S11, which is not described herein again.
Step S32: acquiring a preset arrival time of a target locomotive at a target station;
it can be understood that some unexpected situations may occur when the target locomotive is actually running, such as: the weather is abnormal or other locomotive safety accidents occur during the operation. At this time, the staff may readjust the specific arrival time of the target locomotive at the target station according to the needs of the actual situation, that is, set a preset arrival time for the target locomotive to arrive at the target station according to the needs of the actual situation, and then control the target locomotive to arrive at the target station at the preset arrival time, so as to avoid the occurrence of an accident.
Step S33: and determining the target speed of the target locomotive at the preset arrival time according to the target distance and the preset arrival time, and adjusting the current speed of the target locomotive to the target speed so that the target locomotive arrives at the target station at the preset arrival time.
The purpose of this step is to explain how to enable the target locomotive to reach the target station at the preset arrival time, that is, the target locomotive first calculates the target distance from the target station and the preset arrival time at which the target locomotive arrives at the target station according to the current position of the target locomotive to calculate the target speed at which the target locomotive arrives at the target station at the preset arrival time, and then adjusts the current speed of the target locomotive to the target speed, so that the target locomotive can arrive at the target station at the preset arrival time.
Of course, this is only to provide a method for enabling the target locomotive to reach the target station, and specifically, the current speed of the target locomotive may be adjusted to the target speed by a uniform speed or a non-uniform speed method, which is not described herein again in detail. In practical applications, if the target locomotive needs to reach the target station at the preset arrival time, this operation mode of the target locomotive may be referred to as "limit mode". Obviously, the method in the embodiment can be applied to more complex scenes to meet the requirements of different application scenes.
Referring to fig. 4, based on the disclosure of the above embodiments, the embodiment will explain how to achieve the on-time arrival of the target locomotive by a specific example.
In practical applications, in order to further save the labor consumption, the automatic driving device can be used to control the operation of the target locomotive. Specifically, the operation schedule of the target locomotive may be converted into an operation time point data file of the target locomotive according to a binary data format, the operation time point data file is stored in the automatic driving device, and then the calculation methods of the "slow-moving mode", the "drive-up mode", the "single-click mode" and the "limit-click mode" disclosed in the above embodiments are stored in the automatic driving device in advance so as to facilitate reading and calling of the automatic driving device. In practical applications, the automatic driving device may be replaced with a driving assistance device.
In addition, the slow-moving mode, the overtaking point mode, the single-point mode and the limiting point mode can be displayed through the human-computer operation interface of the automatic driving device, so that a worker can adjust the running state of the target locomotive in real time according to information displayed on the human-computer interaction interface, and the operation experience of the worker is further improved.
After the target locomotive enters automatic driving through the automatic driving device, the target locomotive calculates the traction force of the target locomotive according to the current speed of the target locomotive, the current position of the target locomotive, the target distance between the current position of the target locomotive and a target station and the operation mode of the target locomotive set by the man-machine operation interface, and dynamically adjusts the current speed of the target locomotive so that the target locomotive can reach the target station at the target-to-station moment.
In addition, in the present embodiment, the target locomotive may be switched in any combination of two, three or four operation modes, i.e., the "slow driving mode", the "drive-up mode", the "single-trip-point mode" and the "limit-point mode" during the operation process, as shown in fig. 5. Therefore, the operation process of the target locomotive can be more flexible and changeable, and the method can be suitable for more practical application scenes.
Referring to fig. 6, on the basis of the above embodiments, the present embodiment further describes and optimizes the technical solution. Specifically, step S13: adjusting the current speed of the target locomotive according to the target distance and the target arrival time, so that the target locomotive arrives at the target station at the target arrival time after the process, further comprising:
step S14: judging whether the target locomotive reaches a target station at the target arrival time;
step S15: if not, the early warning information is prompted.
In this embodiment, after the target locomotive reaches the target station, it may be determined whether the target locomotive reaches the target station at the target arrival time, so as to determine the accuracy of the target locomotive reaching the target arrival time. It can be thought that if the target locomotive does not arrive at the target station according to the target arrival time, it indicates that the target locomotive is abnormal in the operation process, at this time, the early warning information can be prompted, so that the working personnel can check the fault problem in real time and remove the fault in time, thereby not only ensuring the safe operation of the target locomotive in the subsequent process, but also avoiding the situation that the target locomotive cannot arrive at the target station at the target arrival time in the subsequent process.
