The automatic predicting and real-time emptying system for the railway dumper unloading time is characterized by comprising a dumper unloading time predicting and emptying module which is arranged based on a railway shipment line and is respectively connected with a railway dispatching command system and a railway signal interlocking system, wherein the dumper unloading time predicting and emptying module is used for acquiring the number N, the name and the unloading parameter t of heavy cattle line from the railway dispatching command system, simultaneously, the railway dispatching command system sends an operation plan to the railway signal interlocking system, the railway signal interlocking system is used for controlling a shunting signaler of the railway shipment line, the dumper unloading time predicting and emptying module is used for acquiring the red light strip appearing/disappearing time of a heavy cattle line stock track circuit from the railway signal interlocking system, predicting and emptying time by calculating the output para-position time, and simultaneously, notifying the emptying time in real time by calculating the output light strip disappearing time.
2. The automatic predicting and real-time emptying system of railway dumper unloading time according to claim 1, wherein the dumper unloading time predicting and emptying module comprises shunting annunciators D1-D6, one heavy cattle line, two empty cattle lines, a dumper positioned at the tail end of the heavy cattle line and a transfer table positioned between the heavy cattle line and the empty cattle line, the occurrence time of red light bands with cars in the shunting annunciators D1-D6 is marked as T1, and the disappearance time of red light bands without cars is marked as T2.
3. The automatic predicting and real-time emptying system of railway dumper unloading time as set forth in claim 2, wherein the unloading time of the dumper unloading time predicting and emptying module is calculated by calculating and obtaining the predicted unloading time of each batch of upper vehicles by adopting a formula of N+T1 in combination with the number N of incoming vehicles of heavy cattle lines, the goods names and the corresponding emptying parameters of a railway dispatching command system, wherein the unloading time of the dumper unloading time predicting and emptying module is calculated by a red light zone vanishing moment T2+emptying parameter T of a shunting annunciator.
4. An automatic predicting and real-time emptying method for the unloading time of a railway dumper is realized based on the automatic predicting and real-time emptying system of the railway dumper, which is characterized by comprising the following steps: S1, acquiring alignment information of a heavy cattle line of a dumper from a railway dispatching command system automatically and in real time through a dumper unloading time prediction and reporting module, wherein the alignment information comprises an alignment number N, a cargo name and unloading parameters T, and the estimated unloading time of the heavy cattle line is automatically measured through T1+ T; S2, when the last heavy truck of the site heavy truck enters the dumper unloading platform, the red light belt of the heavy truck track shunting annunciator synchronously disappears, and the dumper unloading time prediction and emptying module acquires the disappearing time T2 in real time, obtains the emptying time through T2+ T and automatically predicts in real time.

Description

Automatic predicting and real-time emptying system and method for unloading time of railway dumper Technical Field The invention relates to the technical field of automatic identification of railway freight information, in particular to an automatic forecasting and real-time empty reporting system and method for unloading time of a railway dumper. Background The method is characterized in that a dumper is adopted to unload bulk cargos such as coal, mineral powder and the like which are shipped by railways in enterprises, one heavy cattle line is usually adopted on the corresponding railway line, and two empty cattle lines are arranged in a total diagram, and a specific scheme is shown in fig. 1, wherein the dumper is used for loading a group of heavy cattle lines (vehicles c1-c12 in fig. 1, the specific number of the vehicles is about 20-60 according to the effective length of the heavy cattle lines) by a railway locomotive, after the locomotive withdraws from the heavy cattle lines, the dumper is used for loading the heavy cattle onto a dumper unloading platform (c 8 in the diagram) by a dumper iron cattle, and empty vehicles are delivered to the empty cattle lines (empty cattle lines 2 in the diagram and vehicles c9-c12 in the diagram) by a dumper transfer table after the platform is dumped and unloaded. And after all the heavy vehicles on the heavy cattle line are emptied and fed into the empty cattle line, the railway locomotive is hung on the empty cattle line, and then the empty vehicles are taken out, so that one unloading process is completed. According to the above-mentioned flow, it can be seen that the railway dispatch is timely grasping the progress of unloading, when unloading is completed, the unloading plan is issued to the new unloading on the cattle weighing line, the empty car on the empty cattle line is taken away in real time, which is the key for improving the unloading efficiency of the dumper, and most enterprises all rely on the freight operators to observe and confirm the progress of unloading on site manually at present, so that the following defects exist: (1) And the manual operation efficiency is low, and real-time mastering of the unloading progress cannot be realized. The manual confirmation is needed to be confirmed on site according to the estimated emptying time, the estimated accuracy is large according to the difference of different personnel, the unloading clock and the like, and the real-time performance is not high. (2) And the logistics cost of enterprises is high. Because the dumper is operated for 24 hours, at least 4 personnel are arranged for confirmation (relief is not considered) by one dumper, and the special personnel are difficult to be configured along with the increase of the cost reduction pressure of enterprises. Along with the continuous improvement of enterprise railway automation and informatization level, a railway information system is developed to a comprehensive dispatching management and control system comprising a driving system, a freight system and an interlocking system, so that the real-time accurate tracking of the whole transportation flow data is realized, the existing dumper is not provided with automatic prediction and emptying functions on the basis of the flow data, and the actual use requirements cannot be met.
