Description

Blocking rail break monitoring system for railway and method thereof

Technical Field

The invention relates to the technical field of railway monitoring, in particular to a blocking rail break monitoring system and a method thereof for a railway.

Background

In recent years, as seamless tracks have been increased, long tracks have been increased, and stress is hardly removed, so that the phenomenon of breaking of long tracks has been increased. The steel rail is broken for a plurality of reasons, so that the problems can not be fundamentally solved, once the steel rail is broken, the safety of railway transportation is greatly threatened, the train is derailed and overturned, the consequences are extremely serious, and if the train of passengers overturns at high speed, the serious consequences of vehicle damage and human death are caused. In europe with developed high speed railways, accidents caused by rail break occur hundreds of times each year, causing significant property loss and casualties. Therefore, the non-electrified railway semi-automatic blocking broken rail monitoring system comprises a monitoring host, a detection terminal and an insulating part, wherein the insulating part divides a steel rail into a detection area, the monitoring host is connected to the initial end of the steel rail, the detection terminal is connected to the tail end of the steel rail, a plurality of detection terminals are connected to the middle of the steel rail, and the monitoring host is connected with a server through a wireless network.

The monitoring host is connected with the server through a wireless network, and the server is connected with the operation computer and the short message module.

The detection mode and principle of the semi-automatic block rail break monitoring system of the non-electrified railway are as follows: A. the method comprises the steps of real-time detection, wherein when a rail is broken, the tail end of the detection is disconnected, and a host machine sends a detection instruction when detecting the current change of the rail; in addition, faults of all parts in the host computer are also detected in real time; B. detecting at fixed time, wherein the system is set to circularly detect once every 10 minutes, and the host computer sends a detection instruction;

C. detecting the passing of the train, wherein the host sends a detection instruction after the train passes through each time;

broken rail judgment principle: after receiving the detection instruction, each detection terminal sequentially sends a signal of a detection result to the host;

if the rail is broken, all detection terminal signals behind the broken rail point are disconnected; the host machine judges the rail breaking position of the steel rail according to the serial number of the detection terminal receiving the signal; the faults of all parts in the host machine are also detected in real time; the fault of the terminal (tail) end is detected by timing detection and vehicle passing detection; if one or more detection terminals are in fault, the host computer cannot receive corresponding signals, so that the detection tail end or the detection terminal number and the installation position of the fault are judged.

Thus, a set of monitoring device is installed in each semi-automatic block interval non-track circuit section, the blank of track break monitoring is effectively solved, and the track break monitoring can be transplanted for other lines; the method can effectively solve the problem that the rail is not easy to find after the rail fracture failure, thoroughly eradicates the serious consequences of train derailment overturn and vehicle damage and human death possibly caused by rail fracture, and has immeasurable economic and social benefits.

The monitoring host can send the signal of the detection result to the server through the wireless signal, which mainly aims to prevent the signal of the detection result from losing when the monitoring host has problems, because the amount of the signal of the detection result in the monitoring host is increased continuously, in order to prevent the signal of the detection result from losing when the monitoring host has problems, the signal of the detection result needs to be transmitted to the server for storage, thereby ensuring the safety of the signal of the detection result, when the existing monitoring host sends the signal of the detection result to the server through the wireless signal, an intermediate server which is wirelessly connected with the monitoring host and the server is arranged between the monitoring host and the server in advance, the monitoring host firstly transmits the signal of the detection result to the intermediate server through the wireless signal, and then transmits the signal of the detection result to the server through the intermediate server through the wireless signal During the storage, the intermediate server needs to transfer once, so that the signal transmission speed is not good, and the time length of transmitting the signal to the server is prolonged.

In order to avoid damage caused by external impact, the server is placed in a hollow server case, the server case needs to have a good liquid blocking effect, liquid flow caused by condition change in a room where the server case is located due to various accidents can be prevented from permeating into the server case, and the liquid flow leaks onto the server case like a liquid pipeline laid on a ceiling in the room.

the monitoring host machine carries out reduction on a signal of a detection result, namely an initial signal, which needs to be transmitted to the server for storage, and then obtains sub information for storage, namely the capacity of the reduced signal is lower than that of the signal of the detection result, namely the capacity of the initial signal, which needs to be transmitted to the server for storage; running this step can reduce the storage capacity; the signal of the detection result to be transmitted to the server for storage can be reduced to a plurality of pieces of sub information to be stored under the condition that the signal capacity of the detection result to be transmitted to the server for storage is not small, for example, the signal of the detection result to be transmitted to the server for storage has sixteen megabits and can be reduced to six thousand 100 bits of sub information to be stored, and the sub information to be transmitted to the server for storage is reduced by a few compared with the signal of the detection result to be transmitted to the server for storage, so that the transmission speed of the sub information to be transmitted to the server for storage is increased by a few compared with the signal of the detection result to be transmitted to the server for storage.

the method for establishing the wireless link between the monitoring host and the server by the monitoring host comprises the following steps: the wireless link between the monitoring host and the server can be established through the monitoring host or the server, and specifically comprises the following steps: before the wireless link is established, the monitoring host is identified by the server, or the server is identified by the monitoring host, so as to improve the reliability of the wireless link. For example, the server stores the identification information in advance, the identification information is a character string 'wwwkkktttt', the identification information needs to be input into the monitoring host computer, then the identification information is sent to the server to be compared, and after the input identification information is confirmed to be consistent with the identification information stored in the server in advance, the wireless link can be established;

The monitoring host can transmit various sub information for storage under different link conditions, for example, when a wireless link is smooth, the monitoring host transmits the sub information for storage in the order from large to small according to the weight value of a signal corresponding to the sub information for storage, and when the wireless link is blocked, the monitoring host transmits the sub information for storage from small to large according to the capacity of the sub information for storage, so that the purpose of flexibly transmitting a plurality of sub information for storage under different link conditions is achieved, the signal transmission speed is improved, and the time for transmitting the sub information to a server is reduced.

When the wireless link between the monitoring host and the server is blocked, the sub information for storage is not transferred quickly, the sub information for storage is often unsuccessfully transferred and then continuously transferred for a plurality of times, and for the sub information for storage with the weight value of the corresponding signal higher than the weight threshold, if the sub information for storage is continuously transferred for a plurality of times, the probability of leakage of the sub information for storage is increased, and the reliability of the sub information for storage in transfer cannot be ensured; therefore, the sub-information which is less important and has a low weight value and is used for storage is transmitted first, and the contribution of leakage of the sub-information transmission which has a weight value higher than the weight threshold value of the corresponding signal is reduced; when the wireless link between the monitoring host and the server is smooth, the monitoring host transfers the sub information for storage, of which the weight value of the corresponding signal is higher than the weight threshold, to the server in the order of the weight values from high to low, and then transfers the sub information for storage, of which the weight value of the corresponding signal is lower than the weight threshold, to the server in the order of the weight values from high to low, so that the link resources can be fully utilized, the information transfer speed is increased, and the reliability of the sub information for storage can be improved.

The step 5 can further include:

here, the monitoring host can start several processes, and when the wireless link is smooth, several pieces of sub information for storage can be concurrently transferred to the several processes. For example, if the monitoring host starts K processes, the monitoring host can concurrently transfer K pieces of sub information for storage, where K is a natural number. Therefore, a plurality of sub information for storage can be transmitted simultaneously, and compared with the one-by-one transmitted information, the signal transmission speed can be increased.

After step 5, the following method can be performed:

here, the sub information for storage that is not successfully transferred can be monitoring that the host accidentally drops the wireless link upon transferring the sub information for storage, such that the transfer of the sub information for storage is not successful. Generally, after a monitoring host transfers a sub-message for storage to a server, the server responds to a response message if receiving the sub-message for storage, the monitoring host identifies the sub-message for storage as successful in transfer after obtaining the response message, and identifies the sub-message for storage as not transferred if not obtaining the response message.

When the monitoring host cancels the wireless link with the server, the monitoring host stores the sub-information for storage which is not transmitted yet and the sub-information for storage which is not transmitted successfully in a plurality of sub-information for storage, and identifies the sub-information for storage which is not transmitted yet and the sub-information for storage which is not transmitted successfully as the sub-information for storage which is not transmitted;

upon the monitoring host re-establishing a wireless link with the server, the monitoring host communicating to the server sub-information for storage identified as not communicated among the plurality of sub-information for storage; compared with the prior art, when the monitoring host and the server build a wireless link again, the signal transmission speed can be improved without transmitting a plurality of pieces of sub information for storage again.

the monitoring host machine executes the reduction of the signals of the detection results which need to be transmitted to the server for storage by using a hybrid coding method formed by the combination of entropy coding and source coding; specifically, a source coding method is firstly used for reducing a signal of a detection result which needs to be transmitted to a server for storage to obtain a first code, then an entropy coding method is used for reducing the first code again to obtain a second code, and all the second codes are a plurality of sub-information for storage. The entropy encoding method is run length coding, LZW coding, shannon coding, huffman coding, or arithmetic coding. The method comprises the steps of firstly utilizing a source coding method to reduce a signal of a detection result which needs to be transmitted to a server for storage to obtain a first code, then utilizing an entropy coding method to reduce the code again to obtain a second code, wherein all the second codes are a plurality of pieces of sub information used for storage, the reliability of the stored sub information during transmission can be improved, and for the signal of the detection result which needs to be transmitted to the server for storage and is not required to be disclosed or published, the reliability of the transmission of the stored sub information can be improved through two times of coding.

Before proceeding to step 5, the following steps can also be performed:

Here, after the monitoring host performs reduction on the signal of the detection result to be transmitted to the server for storage by using the hybrid coding method, and after the sub-information for storage is obtained, in order that the server can obtain the signal of the detection result to be transmitted to the server for storage in the sub-information for storage after obtaining the sub-information for storage, the monitoring host concurrently transmits the information of the hybrid decoding method corresponding to the hybrid coding method to the server, so that the server performs decoding on the obtained sub-information for storage by using the information of the hybrid decoding method, and then stores the decoded signal on the server.

The present invention has been described in an illustrative manner by the embodiments, and it should be understood by those skilled in the art that the present disclosure is not limited to the embodiments described above, but is capable of various changes, modifications and substitutions without departing from the scope of the present invention.
