Description

Technical Field

[0001] The invention relates to a railway shunting data collection and analysis system and method, belonging to the technical field of railway shunting. Background Art

[0002] Train unmarshaling and shunting operations are key links in railway transportation production. The operating efficiency of this link directly affects the efficiency of the entire train command and transportation production. Therefore, improving shunting efficiency is of positive and important significance to improving overall transportation efficiency and expanding transportation capacity. At present, due to the lack of effective means and data support, the realistic analysis of shunting efficiency only remains at a vague level, the shunting operation time is limited to manual realistic methods, and the shunting efficiency analysis is limited to the shunting time quota determination. It is impossible to systematically, accurately and scientifically analyze the shunting operation volume and even the shunting efficiency, such as the number of shunting hooks, the number of shunting vehicles, the actual running, the running distance, the running speed, etc.

[0003] As an effective implementation and control of shunting operations, the railway flat wireless shunting equipment is a wireless light display system used by shunting masters, locomotive drivers and shunting personnel to transmit wireless shunting signals and communicate. The system consists of locomotive equipment, portable equipment and fixed equipment. Locomotive equipment (on-board station), locomotive equipment consists of a machine controller host (including power supply), driver's voice box, display lights, speakers, antennas, etc. It has the functions of call, signaling recognition and display, and can identify the shunting instructions issued by the shunting personnel, light up the display, give voice prompts, issue responses and record, record signaling, time and other information parameters. Portable equipment (handheld station), portable equipment also includes shunting master handheld radio, brakeman handheld radio, connector handheld radio. The portable equipment consists of a professional radio station equipped with a wireless shunting signaling control device. It has the functions of issuing various shunting instructions to the locomotive, calling the locomotive and the district chief station. Fixed equipment (dispatching desk), which consists of a district chief controller, microphone, antenna and feeder, has the functions of talking and identifying the call signal issued by the shunting master, and can record the conversations of the shunting team members. Each device can be programmed to set the system time parameters, group number, personnel number and other basic identity information.

[0004] However, in the prior art, when it is necessary to retrieve the conversation recordings of the shunting team members, it is necessary to use a USB flash drive or hard disk to export the recordings in the device one by one, or use a data cable to directly export them to a computer. Due to the large capacity of the recording data file, the USB flash drive download is slow, and the read data needs to be read or played with special software. Therefore, the prior art cannot effectively collect, store and analyze the conversations and wireless shunting signals between locomotive equipment, portable devices and fixed equipment, especially when reverse investigation is required, there are difficulties.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the technical features of the solution of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0021] like Figure 1 As shown, a railway shunting data collection and analysis system provided by an embodiment of the present invention includes a shunting signaling monitoring device, a railway plane wireless shunting equipment and a background server, the railway plane wireless shunting equipment includes a wireless light display radio station and a shunting radio station, the wireless light display radio station generates wireless shunting signaling, the shunting radio station modulates the collected wireless shunting signaling and transmits it to the shunting signaling monitoring device, the shunting signaling monitoring device demodulates the received wireless shunting signaling data and then identifies and analyzes it, and transmits the analysis result to the background server, the background server classifies and displays the acquired wireless shunting signaling data, and presents the abnormal analysis situation of the monitoring data on the liquid crystal display interface of the background server.

[0022] As a possible implementation of this embodiment, the wireless communication between the shunting radio station and the wireless light display radio station is coordinated with the wireless shunting signaling of train unmarshaling and shunting operations to transmit the wireless shunting signaling.

[0023] As a possible implementation of this embodiment, at least one shunting signaling monitoring device is configured at each shunting site where shunting data is to be collected.

[0024] As a possible implementation of this embodiment, the shunting signaling monitoring device includes an antenna module, a wireless shunting signaling voice command collection module, a wireless shunting signaling voice command recognition module, a wireless shunting signaling modulation and demodulation module and an industrial computer module. The wireless shunting signaling voice command collection module receives the wireless shunting signaling of the wireless light display radio, and receives the original signal of the light display signaling sent by the shunting master's handheld radio, the brakeman's handheld radio, and the connector's handheld radio. The wireless shunting signaling modulation and demodulation module demodulates the wireless shunting signaling voice collected by the wireless shunting signaling voice command collection module and forms a corresponding digital code by comparing it with the coding table; the wireless shunting signaling voice command recognition module identifies repeated command signals in the wireless shunting signaling and sends them to the industrial computer module after deduplication processing; the industrial computer module intelligently recognizes and analyzes the received audio, and transmits the analysis results to the background server through the antenna module, so as to realize automatic realism, analysis and assessment of the shunting operation process, and finally achieve the goal of improving the production efficiency of the shunting operation.

[0025] As a possible implementation of this embodiment, the specific process of the wireless shunting signaling modulation and demodulation module performing signal demodulation and command analysis on the wireless shunting signaling voice collected by the wireless shunting signaling voice command collection module and forming a corresponding digital code by comparing the coding table is as follows: receiving the wireless shunting signaling to be processed through the receiver; Perform filtering, carrier wave and frequency conversion preprocessing on the received wireless shunting signaling signal; The characteristic information of different modulation modes is obtained through calculation and transformation, and the performance and type of different modulation modes are identified. The time domain characteristics of the communication signal include instantaneous amplitude, instantaneous frequency and instantaneous phase, and the characteristics of the transform domain include the spectral characteristics of the signal; The statistical histogram is used to construct the required features, the linear classifier is used to identify the modulation of the signal, and the corresponding digital code is formed by comparing with the coding table.

[0026] As a possible implementation of this embodiment, the background server classifies and displays the acquired wireless shunting signaling data, and presents the abnormal analysis situation of the monitoring data on the liquid crystal display interface of the background server in the following specific process: Display a map of the jurisdiction area based on the monitoring data, display each station in a specific graphic form on the map of the jurisdiction area based on the geographical location data of each station and form a two-dimensional distribution model, thereby forming a main management interface; Generate monitoring data history curves of each station based on historical values ​​of monitoring data and analysis results, and generate a monitoring data history curve display interface, thereby forming a sub-management interface; Displaying switch buttons corresponding to various monitoring items on the main management interface, and switching displaying different monitoring items on the main management interface by selecting different switch buttons; The graphics representing each station are used as sub-management interface switching links. When a specific station is selected on the main management interface, the sub-management interface of the station is entered to display the historical curve of the monitoring data of the station.

[0027] Since the original signal is not suitable for use as a transmission signal, because the original signal has not been processed and cannot match the transmission channel, the original signal must be modulated. The first step is to preprocess the original signal, extract the signal recognition features and design the classifier. The second step is to obtain the characteristic information of different modulation methods through calculation and transformation, so as to identify the performance and type of different modulation methods. The time domain characteristics of the communication signal include instantaneous amplitude, instantaneous frequency and instantaneous phase, while the characteristics of the transform domain include the frequency of the signal. By analyzing and processing the received original signal, the modulation method of the received signal is finally determined, so as to better provide information and parameters for signal processing.

[0028] The modulation recognition procedure of the wireless shunting signaling modulation and demodulation module mainly includes the reception of shunting signaling, the preprocessing of shunting signaling, the extraction of shunting signaling identification features and the design of classifiers. These links are the general process of modulation recognition. The reception of shunting signaling refers to the reception of the shunting signaling to be processed by the receiver, and preliminary sorting and temporary storage are also required if necessary.

[0029] Among them, the preprocessing of shunting signal refers to various preprocessing of received signals, so as to lay a good foundation for subsequent work. The main tasks include filtering and carrier estimation. However, due to the complexity of high-frequency signals in calculation and processing, frequency conversion work must be performed after receiving the signal to facilitate the subsequent calculation and processing of the signal.

[0030] Information recognition feature extraction is the most critical link, which is related to the accuracy of modulation recognition. First of all, in order to achieve effective signal recognition, it is necessary to pre-process the received signal, and then obtain the characteristic information of different modulation modes through calculation and transformation, so as to identify the performance and type of different modulation modes. The time domain characteristics of communication signals include instantaneous amplitude, instantaneous frequency and instantaneous phase, while the characteristics of the transform domain include the spectral characteristics of the signal, etc. Technicians need to make choices based on the characteristics of different modulation modes to improve the accuracy of modulation recognition.

[0031] The shunting signaling voice command recognition module supports the interaction between the master and slave stations, and recognizes repeated command signals to achieve deduplication; this recognition technology is divided into two aspects: audio wireless reception and voice recognition. The radio station receives real-time operation audio and transmits it to the industrial computer voice recognition system. The voice recognizes the signaling audio and stores the analysis results in the information database through the API interface.

[0032] The storage module in the industrial computer module has a record backup of the command parsing content and supports the storage of voice decoding information for up to 1 month.

[0033] The antenna module is used to transmit electronic data to the backend server through the 4G or 5G network, and supports the function of resuming transmission after network disconnection.

[0034] The software in the backend server, such as the software that displays the main management interface and sub-management interface, needs to be described functionally.

[0035] The shunting signaling monitoring device records the shunting signaling generated during the shunting operation in real time. Combined with the shunting operation plan sheet, the shunting operation plan sheet hooking and cancellation algorithm is designed. The generated shunting signaling is used to record the hooking plan start and end time of each batch of shunting operations.

[0036] Restore the shunting operation process according to the track, quantity, precautions and other contents in the shunting operation sheet. Record the number of mobilization vehicles, actual running, running distance, running speed and other information of the shunting operation, and display them on the LCD. Help optimize the dispatching and operation of trains, and carefully manage the key operation time nodes of shunting operations. With the help of Internet of Things technology, real-time monitoring of vehicles and operation conditions can be achieved, and the operation time of each link can be recorded in detail to support precise management. In terms of analysis and assessment, the operation efficiency is evaluated and optimized through automated data collection, analysis and assessment. Combined with the preset standard operation time and job assessment standards of the station, automatic association of operation time and automatic assessment are realized, which significantly improves the operation efficiency and personnel enthusiasm.

[0037] Through the shunting signaling monitoring device, the shunting train operation plan is transparent, and the shunting operation plan can be flexibly prepared according to the train operation plan, and the shunting operation plan can be prepared in advance. Secondly, the station storage status is transparent, and the occupancy of the lines in the area and the whereabouts of the empty weight of the cars are known at any time, providing an accurate basis for the timely preparation of shunting operation plans and effectively improving the line utilization rate. Thirdly, the shunting machine is dynamic and transparent, fully controlling the progress of shunting operations in the area and coordinating shunting operations in the area.

[0038] The backend server of the present invention has the following functions: 1) Forming the main management interface. The map of the jurisdiction area can be displayed on the LCD display interface. Based on the geographical location data of each station, each station is displayed on the jurisdiction area map with a specific graphic, such as a dot or a triangle. The area size of the above graphic is determined based on the numerical value of each monitoring data and analysis result, and the area size is proportional to the numerical value. This forms a two-dimensional distribution model, thereby forming the main management interface.

[0039] 2) Forming a sub-management interface. The management center generates the monitoring data history curve of each station based on the historical values ​​of the monitoring data and analysis results, and generates a monitoring data history curve display interface, thereby forming a sub-management interface.

[0040] 3) The switch buttons corresponding to the various monitoring items are displayed on the main management interface. By selecting different switch buttons, different monitoring items can be switched and displayed on the main management interface.

[0041] 4) Use the graphics representing each station as a sub-management interface switching link. When a specific station is selected on the main management interface, enter the sub-management interface of the station and display the historical curve of the monitoring data of the station.

[0042] like Figure 2 As shown, a railway shunting data collection and analysis method provided by an embodiment of the present invention includes the following steps: S1, the shunting signaling monitoring device regularly performs the wireless shunting signaling monitoring operation according to the time and cycle information preset in the program, and collects the wireless shunting signaling generated by the wireless light display radio station through the shunting radio station.

[0043] The wireless communication between the shunting radio station and the wireless light display radio station cooperates with the wireless shunting signaling of train unmarshaling and shunting operations to transmit the wireless shunting signaling.

[0044] At least one shunting signaling monitoring device shall be configured at each shunting location where shunting data is to be collected.

[0045] S2, the shunting signaling monitoring device recognizes, removes duplication and converts the voice of the wireless shunting signaling, forms electronic data and sends it to the backend server.

[0046] Specifically, the shunting signaling monitoring device first decodes and parses the wireless shunting signaling voice collected by the wireless shunting signaling voice command collection module, and forms a corresponding digital code according to the coding table; secondly, it identifies repeated command signals in the wireless shunting signaling and performs deduplication processing; then it intelligently identifies and analyzes the audio, and transmits the analysis results to the background server through the antenna module.

[0047] S3, the backend server receives the monitoring data uploaded by the shunting signaling monitoring device, classifies and displays the acquired monitoring data, and presents the abnormal analysis situation of the monitoring data on the liquid crystal display interface of the backend server.

[0048] Specifically, the background server first displays a map of the jurisdiction area based on the monitoring data, and displays each station in a specific graphic form on the jurisdiction area map based on the geographical location data of each station and forms a two-dimensional distribution model, thereby forming a main management interface; secondly, based on the historical values ​​of the monitoring data and analysis results, a monitoring data history curve of each station is generated, and a monitoring data history curve display interface is generated, thereby forming a sub-management interface; then, the switching buttons corresponding to each monitoring item are displayed on the main management interface, and different monitoring items are switched and displayed on the main management interface by selecting different switching buttons; finally, the graphics representing each station are used as sub-management interface switching links. When a specific station is selected on the main management interface, the sub-management interface of the station is entered to display the monitoring data history curve of the station.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
