[0007] The carriage monitoring system is deployed inside each carriage to monitor the public areas in each carriage of the EMU;

[0008] The pantograph monitoring system is deployed inside some carriages to monitor the status of the roof pantograph and the contact grid.

[0009] The technical solution provided by the embodiment of the present invention includes the following beneficial effects: a car monitoring system and a pantograph monitoring system are designed to form a complete EMU video monitoring system, and in a car where the car monitoring system and the pantograph monitoring system are deployed at the same time, the car monitoring system and the pantograph monitoring system share a server, thereby reducing the resource consumption of setting up the server.

[0016] System Example

[0017] According to an embodiment of the present invention, a train video monitoring system is provided. Figure 1 Schematic diagram of a train video monitoring system according to an embodiment of the present invention. Figure 1 As shown, the train video monitoring system according to the embodiment of the present invention specifically includes:

[0018] Carriage monitoring system and pantograph monitoring system, wherein in a carriage where both the carriage monitoring system and the pantograph monitoring system are deployed, the carriage monitoring system and the pantograph monitoring system share a vehicle-mounted server, and the shared server can meet both the vehicle-mounted service requirements of the carriage monitoring system and the vehicle-mounted service requirements of the pantograph monitoring system;

[0019] The carriage monitoring system 10 is deployed inside each carriage and is used to monitor the public areas in each carriage of the EMU. It specifically includes: a panoramic camera module, a hemispherical camera module, an onboard server and an external authorization device, wherein:

[0020] The panoramic camera module is deployed at the doors at both ends of the carriage. A panoramic network camera is installed at the door of each carriage of the EMU. The hemispherical camera module is deployed at the top of the corridor of the passenger area in the carriage. Two hemispherical cameras are installed in the passenger compartment of the carriage, respectively located at the end of the passenger compartment or one-third of the distance from the end. Preferably, a panoramic camera or a hemispherical camera is added as appropriate in special carriages.

[0021] The panoramic camera module and hemispherical camera module use high-definition network cameras to shoot video images in real time, and store the video images in the vehicle server via Ethernet transmission;

[0022] The vehicle-mounted server is deployed in an electrical cabinet at one end of the vehicle compartment, receives video images and transmits them to an external authorization device, and provides power for the panoramic camera module, that is, mainly provides power for the camera;

[0023] The vehicle server is specifically used for:

[0024] Newly captured video images shall be stored and overwrite existing video images in the order of shooting time according to the first-in-first-out principle, and the storage time shall be no less than thirty days.

[0025] The external authorization device is used to play the received video images;

[0026] External authorization devices are specifically used for:

[0027] Record preview, query, playback, download, time calibration operations and hard disk information, package them into log files at predetermined time intervals, and transmit the log files to the vehicle server for storage.

[0028] The carriage monitoring system 10 is specifically used for monitoring the area within each carriage by adopting a networking or non-networking monitoring method between carriages. Non-networking is a single-car storage solution without centralized monitoring.

[0029] Figure 2 Schematic diagram of the topology design of the carriage monitoring system according to an embodiment of the present invention. Figure 2 As shown, taking an 8-car formation as an example, the relationship between the panoramic camera module, the hemispherical camera module, the vehicle-mounted server and the external authorization device is demonstrated.

[0030] The pantograph monitoring system 12 is deployed inside some carriages to monitor the pantograph on the roof and the contact network status, and specifically includes: a pantograph camera module, an on-board server and a monitoring screen, wherein:

[0031] The pantograph camera module is installed on the outside of the roof of some carriages, and is used to obtain the video images of the pantograph status and the contact network status outside the vehicle body by using an integrated camera group; the pantograph camera module specifically includes: a camera, a fill light and a heated glass, among which,

[0032] The fill light obtains the bow raising and lowering signal through the vehicle-mounted server, and based on the pre-defined automatic control rules, controls the filling light switch to be turned on or off according to the bow raising and lowering signal; the fill light is specifically used for: obtaining the bow raising and lowering signal through the input and output interface of the vehicle-mounted server; the automatic control rules specifically include: the fill light automatically turns off after the bow is lowered for a certain threshold time. In this embodiment, the fill light automatically turns off two minutes after the bow is lowered.

[0033] Heated glass senses external temperature changes and controls automatic heating according to the temperature value.

[0034] The onboard server is the server of the carriage monitoring system corresponding to the carriage, which is used to receive video images and provide power for the pantograph camera module. The onboard server receives the video collected by the pantograph camera module through Ethernet. The onboard server and VES and other systems share Ethernet or EoC coaxial bus. The Ethernet cable adopts twisted shielded industrial Ethernet cable, which meets the relevant standards for EMU cables. The onboard server adopts a 2.5-inch SATA interface hard disk. The hard disk box should be easy to disassemble and install and have anti-theft measures.

[0035] The on-board server of the pantograph monitoring system includes both the pantograph function and the carriage monitoring function, that is to say, in a carriage where both the carriage monitoring system and the pantograph monitoring system are deployed at the same time, the carriage monitoring system and the pantograph monitoring system share a server.

[0036] The monitoring screen is deployed in the mechanic's room of the EMU. Because there is a passenger information PIS system or a train evaluation VES system in the mechanic's room, the monitoring screen is used to play the received video images. Preferably, an intelligent analysis host can also be used to receive video images, perform intelligent analysis on the video images, and transmit the alarm information obtained after the analysis to the monitoring screen for display. In addition, the monitoring screen can view the online status and IP address of the on-board server and camera, as well as the status of the fill light, etc.

[0037] The pantograph monitoring system is specifically used for: monitoring by Ethernet networking between carriages. The pantograph monitoring system realizes network communication through internal networking, and centrally controls and displays in real time through the monitoring screen. Figure 3 Schematic diagram of the topology design of the pantograph monitoring system according to an embodiment of the present invention. Figure 3 As shown, taking an 8-car formation as an example, the topology of the centralized networking of each car of the pantograph monitoring system is demonstrated.

[0038] To sum up, in response to the existing problems, this invention invents a EMU video surveillance system, designs a car monitoring system and a pantograph monitoring system to form a complete EMU video surveillance system, and in the car where the car monitoring system and the pantograph monitoring system are deployed at the same time, the car monitoring system and the pantograph monitoring system share a server, reducing the resource consumption of building the server; the car monitoring system adopts a decentralized monitoring networking solution, which is convenient for the responsible personnel of each car to monitor the internal situation of each car, and the pantograph status is more related to the safe operation status of the EMU, and not every car is deployed with a pantograph monitoring system, so the pantograph monitoring system adopts a centralized networking method, which is convenient for unified viewing and diagnosis in the mechanic's room or the driver's cab, thereby improving the monitoring efficiency.

[0039] 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 aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
