Embodiment Construction

[0012] The invention is further described in conjunction with the accompanying drawings. The present invention realizes the seamless integration with the train control and management system TCMS through the TRDP (Train Real-time Data Protocol) protocol based on the ECN (Ethernet ConsistNetwork) Ethernet communication network. In this way, the real-time sending and receiving of the monitoring data of the train control and management system TCMS is realized, and the isolation from the train control and management system TCMS is realized through the firewall based on the TRDP protocol.

[0013] The invention realizes train state monitoring, fault diagnosis and fault early warning in the form of graphs, curves and tables through a workstation. The invention integrates a workstation and a mobile communication gateway TLR (Mobile Communication Gateway) to realize wireless uploading of train data, enabling the operation control center OCC and the depot control center DCC to perform re...

Abstract

The invention discloses a wireless uploading and expert diagnosis system for an intermediate and low speed magnetic levitation train based on a TRDP (Train Real-time Data Protocol) protocol. The system comprises an expert diagnosis system and a wireless uploading system. The expert diagnosis system is used for carrying out real-time monitoring, fault smart diagnosis and fault early warning and isisolated with a train control and management system (TCMS) through utilization of a firewall based on the TRDP protocol, thereby preventing a network attack. The wireless uploading system is used forcommunicating with the TCMS and the expert diagnosis system through utilization of the Ethernet, obtaining train fault, state and early warning information and uploading the information to a ground server through utilization of wireless network. According to the system, vehicle operation is monitored visually in forms such as a chart and a curve, information such as vehicle states and faults is wirelessly uploaded, an operation control center (OCC) and a vehicle depot control center (DCC) can monitor train states remotely in real time, and the train operation security and train maintainabilityare improved.

Description

technical field [0001] The invention relates to the technical field of medium and low-speed maglev trains, in particular to a wireless upload and expert diagnosis system for medium and low-speed maglev trains based on the TRDP protocol. Background technique [0002] At present, the new generation of medium and low-speed maglev trains in China is in the development stage, and there is no mature wireless uploading and expert diagnosis technology. Under the prior art, the current train status can only be monitored through each page of the driver's display screen HMI. It is impossible to intuitively monitor vehicle operation through charts, curves, etc.; wireless upload of information such as vehicle status and faults cannot be realized, and the operation control center OCC and depot control center DCC cannot remotely monitor the train status in real time. Contents of the invention [0003] Aiming at the defects of the above-mentioned prior art, the present invention provides...
