【摘要】：安全是鐵路運輸永恒的主題。隨著我國鐵路隨著“高速、重載”的方向發(fā)展,對運行中的鐵路貨車進行實時監(jiān)控、及時掌握車輛的運行安全狀況十分必要。由于鐵路貨車需要頻繁地解列編組,車輛間無通訊電纜,因此對無線監(jiān)測提出了較高的要求;此外,由于鐵路貨車無車載供電裝置,且難以通過電力線纜連接至機車進行集中供電,需解決供電問題。常規(guī)的地面監(jiān)測模式需要在軌邊進行大規(guī)模的聯(lián)網(wǎng)建設(shè),不僅設(shè)備成本高、維護不方便,而且難以實時在線監(jiān)測車輛的運行狀態(tài)。近年來,新興的物聯(lián)網(wǎng)技術(shù)憑借其諸多優(yōu)勢,在智能家居、智能電網(wǎng)、智能農(nóng)業(yè)、智能交通等領(lǐng)域得到了廣泛應(yīng)用。將物聯(lián)網(wǎng)技術(shù)應(yīng)用到鐵路貨車,必將有力促進鐵路運輸安全事業(yè)的發(fā)展。本文結(jié)合鐵路貨車的實際應(yīng)用需求,設(shè)計了一套基于物聯(lián)網(wǎng)的鐵路貨車行車狀態(tài)在線監(jiān)測系統(tǒng)。論文主要從ZigBee無線傳感網(wǎng)絡(luò)、機車監(jiān)控平臺和地面監(jiān)控中心上位機三部分展開研究與設(shè)計。ZigBee無線傳感網(wǎng)絡(luò)以TI的CC2530射頻芯片為核心,包括車廂節(jié)點和機車節(jié)點兩種網(wǎng)絡(luò)設(shè)備。其中,車廂節(jié)點作為網(wǎng)絡(luò)路由器負(fù)責(zé)軸溫、煙霧和溫濕度傳感器數(shù)據(jù)的采集和傳輸,并擴大ZigBee無線網(wǎng)絡(luò)的通信范圍;機車節(jié)點作為網(wǎng)絡(luò)協(xié)調(diào)器負(fù)責(zé)ZigBee網(wǎng)絡(luò)的建立、控制車廂節(jié)點的加入、接收各車廂節(jié)點發(fā)送的數(shù)據(jù)以及向或從機車監(jiān)控平臺上傳或接收數(shù)據(jù)。為了滿足鐵路貨車頻繁解列編組環(huán)境對列車組網(wǎng)的需求,本文設(shè)計了 ZigBee MAC地址白名單驗證算法,以實現(xiàn)車廂節(jié)點入網(wǎng)的驗證識別。機車監(jiān)控平臺是整個監(jiān)測系統(tǒng)運行的核心,主要負(fù)責(zé)收集ZigBee網(wǎng)絡(luò)上傳的各車廂監(jiān)視項的所有信息,然后以人機界面的方式實時顯示列車運行中可能出現(xiàn)的各種故障信息,使得司乘人員能夠?qū)崟r掌握整列車的運行狀況。本文采用ARM+Linux技術(shù)構(gòu)建了機車監(jiān)控平臺嵌入式軟硬件開發(fā)環(huán)境;采用Qt/Embedded圖形框架開發(fā)了一款嵌入式平臺運行的機車監(jiān)控軟件,該軟件可實現(xiàn)列車編組管理、串口數(shù)據(jù)接收處理、狀態(tài)參數(shù)實時顯示、GPRS數(shù)據(jù)發(fā)送、數(shù)據(jù)存儲與查詢、列車網(wǎng)絡(luò)狀態(tài)控制等功能。地面監(jiān)控中心上位機基于Qt的TCP網(wǎng)絡(luò)通信,實現(xiàn)了 GPRS數(shù)據(jù)實時接收、處理、顯示和存儲等功能,便于地面專家對歷史數(shù)據(jù)進行查詢和故障診斷。最后,本文對整個監(jiān)測系統(tǒng)進行了聯(lián)調(diào)測試。測試結(jié)果表明,在實驗室環(huán)境下,該系統(tǒng)達到了較好的實時在線監(jiān)測效果,在鐵路貨車行車安全監(jiān)測領(lǐng)域具有廣泛的應(yīng)用前景。
[Abstract]:Safety is the eternal theme of railway transportation. With the development of high speed and heavy load railway in our country, it is necessary to monitor the running railway freight cars in real time and grasp the running safety condition of the rolling stock in time. Since railway trucks need to be unmarshalled frequently and there is no communication cable between them, a higher requirement is put forward for wireless monitoring. In addition, since there is no on-board power supply device for railway trucks, And it is difficult to connect to locomotive through power cable for centralized power supply, so the problem of power supply should be solved. The conventional ground monitoring mode requires a large-scale network construction on the side of the rail. It is difficult to monitor the running state of the vehicle in real time and online because of the high cost of the equipment and the inconvenient maintenance. In recent years, the emerging Internet of things technology, with its many advantages, has been widely used in smart home, smart grid, intelligent agriculture, intelligent transportation and other fields. The application of Internet of things technology to railway freight cars will promote the development of railway transportation safety. According to the practical application requirement of railway freight cars, a set of on-line monitoring system of railway freight car running status based on Internet of things is designed in this paper. The research and design of ZigBee wireless sensor network, locomotive monitoring platform and ground monitoring center are mainly carried out in this paper. The core of ZigBee wireless sensor network is CC2530 RF chip of TI, which includes two kinds of network equipment: car node and locomotive node. The bus node acts as the network router to collect and transmit the data of the axle temperature, smoke and temperature and humidity sensor, and expands the communication range of the ZigBee wireless network, and the locomotive node is responsible for the establishment of the ZigBee network as the network coordinator. Control the addition of car nodes, receive the data sent by each compartment node and upload or receive data to or from the locomotive monitoring platform. In order to meet the needs of train network in railway freight car frequent unmarshalling environment, a verification algorithm of ZigBee MAC address whitelist is designed in this paper to realize the verification and identification of train nodes entering the network. The locomotive monitoring platform is the core of the whole monitoring system. It is mainly responsible for collecting all the information of the monitoring items uploaded by ZigBee network, and then displaying all kinds of fault information that may appear in the train operation in the way of man-machine interface in real time. So that the crew can grasp the operation of the whole train in real time. In this paper, the embedded software and hardware development environment of locomotive monitoring platform is constructed with arm Linux technology, and a locomotive monitoring software is developed by using QT / embedded graphic framework, which can realize train marshalling management, serial port data receiving and processing. State parameters real-time display GPRS data transmission, data storage and query, train network state control and other functions. The TCP network communication based on QT in the upper computer of the ground monitoring center realizes the functions of receiving, processing, displaying and storing the GPRS data in real time, which is convenient for the ground experts to query and diagnose the historical data. Finally, the whole monitoring system is tested. The test results show that the system achieves a good real-time on-line monitoring effect in the laboratory environment and has a wide application prospect in the field of railway freight car safety monitoring.
