The types of service devices installed in the cab and the room are merely examples, and some of them may be omitted or a new service device may be added as needed, and the present invention is limited to the type and quantity of service devices Or is obvious to a person skilled in the art.

FIG. 2 is a diagram illustrating a dual network configuration of a four-vehicle single-rail vehicle having two cabins and four rooms according to an embodiment of the present invention. FIG. FIG. 2 is a diagram illustrating a dual network configuration of a train. As shown in FIG. 2 and FIG. 3, there are differences in the number of the rooms and the presence or absence of the combination of the rooms, compared with the structure of the train shown in FIG. 1. Only the service devices installed in the cab and cabinets are Ethernet ) And CAN (dotted line), so that detailed description of the detailed configuration will be omitted.

The present invention relates to a network configuration of various service apparatuses installed in a cabin and a cabin. As shown in FIG. 1, an Ethernet (indicated by a solid line) and a CAN bus (indicated by a dotted line) The present invention is characterized in that a dual network is constructed by using the network. According to such a dual network configuration, CAN can be used mainly for local communication between a cab or a service apparatus installed in a room, and in case of global communication such as cab to cab, cabin, or cab, This can be used mainly.

CAN is a serial communication technology first developed by Bosch for vehicle network in 1985. It is a serial bus type network for network construction among various electronic devices in a vehicle and processes messages according to priority. The CAN scheme does not require a specific network address assignment to identify each device as the manner in which all devices connected to the network receive messages. On the other hand, in order to transmit and receive data using Ethernet for high-speed communication, a network address is required to identify the data transmitting and receiving apparatuses. In order to configure the Ethernet-based network, an address must be assigned to various devices connected to the network. However, there is a problem in setting the network address every time in an environment where the network environment of the train is variable due to variable organization, There is.

Accordingly, the present invention proposes a method of automatically configuring network addresses of devices in a network constituting a network of a train using a network requiring network address setting of the device such as Ethernet.

FIG. 4 shows an example of a service device arrangement in a cabin to which the present invention is applied, and FIG. 5 shows an example of a service device arrangement in a cabin. As shown, since two or more identical service devices (e.g., side controllers (SCBs, CCTVs, etc.) can be installed in the cab if necessary), the same service devices are also identifiable A network address will be required. Similarly, it is shown that several LCD devices may be installed in the room shown in FIG.

6 shows a flowchart of a dual network construction method of a train according to an embodiment of the present invention. The network configuration operation according to the present invention can be performed at network initialization setting, or when a variable situation of the network environment occurs, such as a change in the number of vehicles, a variable combination of two or more, or a change of a communication device for a partial electric vehicle in some electric vehicles, Will be performed for dynamic configuration. In addition, the network configuration operation according to the present invention can be performed in each vehicle when the network initialization setting is performed, and when the network change occurs only for a specific vehicle, the network configuration operation can be performed for the vehicle.

Meanwhile, according to an embodiment of the present invention, the network configuration operation can be performed by a service control device or a service control device connected in series with the vehicle control computer through RS485 serial communication among the service devices inside the vehicle. For example, referring to FIG. 1, a voice broadcasting module (ABM) 112 connected in series with a knitting control computer 111 in a cabin will perform a dual network configuration operation according to the present invention. However, the voice broadcasting module ABM is not limited to performing the network configuration operation according to the present invention, and any service device connected in series with the cabin control computer of the cabin or the cabin control computer of the cabin may be a dual network configuration It is apparent to those skilled in the art that the operation can be performed. In addition, in an alternative embodiment, an apparatus for performing the network configuration according to the present invention may be implemented separately from the service apparatus so as to be connected to the organizing control computer or the vehicle control computer through serial communication, and a plurality of service apparatuses Or may be implemented as a connected configuration.

First, in step 610, the vehicle number of the vehicle is received from the knitting control computer or the vehicle control computer. In one embodiment, the vehicle number may be received from the knob control computer or the vehicle control computer via RS485 serial communication.

In step 620, the car number is communicated to a plurality of service devices connected through the first communication network. In one embodiment, the first communications network, as a CAN, will be responsible for local communications between service devices within the vehicle.

In step 630, the network address of the service device generated using the vehicle number, the service device identifier, and the rotary switch value of the service device is received from each of the plurality of service devices and stored.

In one embodiment, the network address of the service device is generated by the service device itself that received the vehicle number. The network address generated by the service device may follow the IP address scheme. Specifically, the first and second addresses of the IP address are predetermined, the third address of the IP address is set to the car number, and the fourth address is set to the combination of the service device identifier and the rotary switch value of the service device (Eg, IP address: aaa.bbb.car number, service device identifier + rotary switch value).

In one example, the service device identifier is information indicating the service device type, and an identifier of 10 units may be assigned to the same service device type. For example, the audio broadcasting module (ABM) 10, the audio image streaming server (AVS) 20, and the network image storage module (NVR) 30 are allocated.

The rotary switch value is a switch value that is set for each position of the same device at the time of initial installation or replacement when one or more identical service devices are installed in the vehicle. For example, in the case of FIG. 5, four LCDs are installed in the cabin. The LCD 1 will be set to the rotary switch 0, the LCD 2 to the rotary switch 1, the LCD 3 to the rotary switch 2, and the LCD 4 to the rotary switch 4.

If the ABM installed in the cabin (vehicle number 1) generates its own IP address (assuming that the first address of the IP address is designated as "172 ", the second address is designated as" 16 & "172. 16. 1. 11" may be generated.

 Referring to FIGS. 7A to 7C, the Ethernet network address generated for the service devices in the cabin (car number 1), room 1 (car number 2), room 9 (car number 10) The tables described are shown.

The network addresses generated and received by each of the service devices in the manner described above will be used by the service devices as the network addresses required for setting up the second communication network. In one embodiment, the second communication network is Ethernet.

In addition, since the network address of the service device includes the information of the vehicle and the vehicle in which the service device is installed, it is possible to control the operation of the service device in the vehicle by position. For example, when an emergency situation occurs in the room shown in FIG. 5, the passenger will attempt to make a call using the emergency interphone (EMP). At this time, the driver uses the network address of the emergency interphone, Information can be grasped and the operation of the CCTV close to the CCTV can be controlled.
