Problems solved by technology

[0032] If the mode of "replacing vehicles in a formation" or "changing the number of vehicles in a formation" is scheduled in advance, this problem can be solved by setting the IP address of each device in each vehicle in advance, but in actual It is very difficult to use. Whenever "replacement of vehicles in a formation" or "change in the number of vehicles in a formation" occurs, it is necessary to change the database setting of the management device 1A-7. In the case of changing this setting, it is not necessary to Meets requirements for system recovery in minutes

Embodiment 1

[0085] Figures 1A-1E Showing the configuration of the network management system of Embodiment 1 of the present invention, Figure 1A (a) is a schematic configuration diagram showing a monitoring system in a four-vehicle formation consisting of a vehicle 21a of vehicle number 1 to a vehicle 21d of vehicle number 4, Figures 1B-1E (b)-(e) are figures which show the configuration table of each vehicle 21a-21d.

[0086]The monitoring system of vehicle 21a of vehicle number 1 is composed of, for example, four monitoring cameras 1-1 to 1-4, video recording device 1-5, display device 1-6, management device 1-7, network switch 1-8 (SW1), The vehicle device 1-9 and a network router 1-10 (RT1) (connection device between networks) are configured to connect the networks to each other, and the router 1-10 is connected to the surveillance cameras 1-1 to 1-4 and the video recording device 1-5 , and connected to the display device 1-6 and the management device 1-7 via the network switch 1-...

Embodiment 2

[0110] Next, a network management system according to Embodiment 2 of the present invention will be described.

[0111] This second embodiment shows a mode in which automatic update setting can be performed on the database managed in advance by the management device 1-7 in the event of "replacement of vehicles in the formation" or "change in the number of vehicles in one formation".

[0112] Figures 7A-7D It is an explanatory diagram showing a database management method using the LLDP (Link Layer Discovery Protocol) function of the router at the time of replacement of vehicles in the network management system according to the second embodiment of the present invention.

[0113] Figure 8 It is a flow chart showing the flow of database management using the LLDP (Link Layer Discovery Protocol) function in the router at the time of replacement of the formation vehicles in the network management system according to the second embodiment of the present invention.

Abstract

A network management system which can easily rebuild the system even when a switch in the configuration of cars occurs. A monitor apparatus including monitor cameras (1-1˜1-4, . . . ) and recording devices (1-5, . . . ) in each car (21a, 21b, . . . ) is networked. Each intra-car network is constructed as a LAN, a router (1-10 (RT1), . . . ) is connected to the LAN in each car, and an inter-car network is constructed as a WAN. The same apparatus in each car and apparatuses provided at the same positions are connected to a port of the same port number and the same LAN address is allocated to such an apparatus. As for an access from a WAN side, which apparatus is accessed is defined only by a difference in port number. Network information of the car switched car can be set merely by switching the setting of the WAN address of the router, . . . .

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Japanese Patent Application No. 2010-073440 for which it applied on March 26, 2010, The content is taken in in this application by reference. technical field [0003] The present invention relates to a monitoring system, which is equipped with monitoring equipment such as a monitoring camera and a recording device in a railway vehicle, monitors the situation in the vehicle, and records the image data in the recording device. In particular, the present invention relates to a network management system And the connection device between networks, even when the configuration of the network is changed due to "replacement of vehicles in the formation" or "change in the number of vehicles in one formation", system reconfiguration can be easily performed. Background technique [0004] In recent years, a network management system in the form of monitoring has been applied. The network mana...
