Problems solved by technology
In addition, since each network works independently and data flows from the two networks to the machine, there is a problem that the machine cannot judge which data should be selected as the valid value (Valid), or the judgment becomes very difficult.
In addition, the signal between the transmission device and the equipment is currently switched by a relay. In this case, it is necessary to switch the output of the transmission device of all vehicles, but there are cases where only a part of them is switched when there is an abnormality in the network. question

Embodiment Construction
[0023] An embodiment of the present invention will now be described with reference to the accompanying drawings, particularly FIG. 2 thereof. The same numerals referred to herein denote the same or corresponding parts in a plurality of cases.
[0024] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
[0025] FIG. 1 shows the structure of a railway vehicle transmission system according to an embodiment of the present invention, and FIG. 2 shows the structure of a transmission switch in the railway vehicle transmission system. The transmitters 1a to 1e of the first system and the transmitters 1a' to 1e' of the second system are mounted on the respective vehicles. The transmitters 1a to 1e of one system are connected point-to-point on the trunk transmission lines 3a to 3d of one system to transmit and receive data. The transmitters 1a' to 1e' of the two systems are connected point-to-point on the trunk transmission lines 3a' t...

A duplicated transmission system for rail vehicles in which exchange of data between rail vehicles is performed by a network, including transmitters having more than one transmission port and that transmit data received from any port to a required transmission port in accordance with prescribed instructions and transmission paths that connect the transmitters. This duplicated transmission system also includes: a transmission switch (2) that connects by branch transmission paths (4), (4') system 1 transmitters (1) and system 2 transmitters (1') arranged in the same vehicle, and various types of devices (5) arranged in the vehicle. The transmission switch transmits data received from the devices to a system 1 transmitter and system 2 transmitter, and of the received data from the system 1 transmitters and system 2 transmitters, only data that is identified by the transmission switch, from the destination address of the received data or the source address thereof, as being of the prioritized system is arranged to be transmitted to the device.
Description
field of invention [0001] The present invention relates to a transmission system for railway vehicles, and more particularly to a transmission system for railway vehicles using a network. Background technique [0002] When a railway vehicle network is configured using Ethernet (registered trademark of XEROX Corporation) compliant with the IEEE802.3 standard, which is a representative general-purpose network, the network has a single-layer bus network structure. On the other hand, in railway vehicles, it is more necessary to ensure safety from the viewpoint of personnel transportation, so redundancy is required, and therefore a duplex network using two sets of one-column bus-shaped networks is required. Therefore, in the existing transmission system for railway vehicles and the equipment connected to it, the two-way transmission system and equipment are connected through the multi-point connection of RS (Recommended Standard)-485. [0003] However, the mainstream of networks...
