Example 3

The above-described preferred embodiments of this embodiment are further exemplified below.

In the related art, when monitoring a railway vehicle, the intelligence of the vehicle is realized by automatically recognizing the type and quantity of goods through a radio frequency identification technology (RFID); in addition, although the intelligent vehicle in the related art is provided with the vehicle-mounted monitoring system, the sensor type, the system composition and the working principle of the intelligent vehicle are different from those of the scheme, and the embodiment provides a solution of the intelligent railway wagon in the aspects of sensor arrangement, a vehicle-mounted gateway, a communication mode, a ground management platform, a mobile terminal and the like.

The railway freight car usually takes general mechanical technology as the main, realizes vehicle running performance and safety monitoring through ground 5T equipment, but because the monitoring equipment of 5T system can only be arranged at fixed point along the railway, if the distance is generally tens of kilometers, then there is no monitoring ability in the interval, thus there is monitoring blind area of longer time and distance. Therefore, the 5T system realizes discontinuous monitoring, and safety accidents can occur due to the fact that vehicle operation faults or abnormal conditions cannot be early warned in time. In addition, the 5T system monitoring service is oriented to all-road vehicles, mainly monitors general safety performance parameters of various vehicles, and is difficult to realize customized monitoring for special monitoring requirements of novel trucks such as current heavy load, rapidness, cold chain and multimodal transportation.

Because the railway freight train adopts an operating mode of unfixed attachment, the freight train needs to be frequently disassembled and regrouped, and the railway freight train is generally unattended, the factors determine that the railway freight train does not have power generation and power receiving capabilities for a long time, and the informatization and intelligent development of the railway freight train is restricted. With the rapid development of information technologies such as internet of things, big data and cloud computing, a new generation of information technology is deeply integrated with a rail transit equipment technology, and the development trend of railway wagon intellectualization is triggered.

The intelligent railway wagon with the vehicle-mounted intelligent monitoring system can realize online real-time monitoring of vehicle running performance and safety, plays an important role in guaranteeing vehicle running safety, relieving train inspection operation workload and reducing maintenance and repair cost, and the embodiment can be combined with information technologies such as the current rapidly-developed Internet of things and wireless communication, and provides an intelligent railway wagon technical scheme.

In the related technology, about 80 thousands of various general and special railway wagons such as open wagons, boxcars, flatcars, tank wagons, hopper wagons and the like are used, although the quantity is large and the variety is large, most railway wagons do not have self-generating capacity or power receiving conditions except that a small quantity of special wagons and refrigerated trucks need to receive power from locomotives or carry diesel generator sets, and basically have no vehicle-mounted information equipment, and the running state and safety monitoring of the railway wagons are realized mainly by means of 5T equipment arranged at fixed points along the railway.

As can be seen from the above, the following disadvantages mainly exist in the related art: the vehicle has no power receiving or generating capacity, no vehicle-mounted intelligent equipment is provided, and the vehicle informatization management level is low; the running state and safety of the vehicle are monitored at fixed points by ground 5T equipment, and continuous monitoring, dynamic monitoring and real-time monitoring cannot be realized; the monitoring parameters and the equipment type are solidified, so that the method is not suitable for various new monitoring requirements of the current heavy-load, quick and multi-type combined transport truck.

The technical problem solved by the embodiment can be overcome and the defects that the existing railway wagon can only carry out fixed-point running state and safety monitoring through 5T equipment can be overcome, and continuous monitoring, dynamic monitoring and real-time monitoring of the running state and the safety monitoring of the railway wagon can be realized according to the specific wagon type and the cargo carrying requirement, so that the application safety of the railway wagon is ensured, and the application, maintenance and overhaul costs are reduced.
