The antenna device is installed on any of outer peripheral surfaces of the case. The first wireless router device transmits collected operation data of the vehicle control device via the antenna device and a first wireless communication network to a second wireless router device arranged in a second railroad vehicle so that a gateway router also arranged in the second railroad vehicle can transmit the collected operation data to an external server via a second wireless communication network. ## Claims ### Claim 1 A vehicle control device for a first railroad vehicle, comprising: a case; an antenna device connected to a first wireless router device; and the first wireless router device housed in the case and configured to transmit collected operation data of the vehicle control device via a first wireless communication network, established between the antenna device and an antenna connected to a second wireless router device, to the second wireless router device arranged in a second railroad vehicle so that a gateway router also arranged in the second railroad vehicle can transmit the collected operation data to an external server via a second wireless communication network. ### Claim 2 (depends on 1) The vehicle control device according to claim 1, wherein the antenna device includes multiple antennas. ### Claim 3 (depends on 2) The vehicle control device according to claim 2, wherein the antennas are installed on different outer peripheral surfaces of the case. ### Claim 4 (depends on 2) The vehicle control device according to claim 2, wherein the antennas are installed on the same outer peripheral surface of the case. ### Claim 5 (depends on 4) The vehicle control device according to claim 4, wherein the antennas extend vertically and extension directions of the antennas are parallel to each other. ### Claim 6 (depends on 5) The vehicle control device according to claim 5, wherein center positions of the antennas are at substantially the same height. ### Claim 7 (depends on 5) The vehicle control device according to claim 5, wherein center positions of the antennas are at different heights. ### Claim 8 (depends on 6) The vehicle control device according to claim 6, wherein an upper position of one of the antennas is higher than a lower position of another of the antennas. ### Claim 9 (depends on 1) The vehicle control device according to claim 1, wherein the antenna device is electrically connected to the first wireless router device via a coaxial cable. ### Claim 10 (depends on 1) The vehicle control device according to claim 1, wherein the antenna device extends through the case to be directly connected to the first wireless router device. ### Claim 11 A vehicle control system for a railroad vehicle, comprising: a gateway router configured to transmit operation data to an external server via a first wireless communication network; a wireless router device that is housed in a case and mounted on the railroad vehicle, and configured to collect and transmit the operation data to the gateway router via a second wireless communication network; and an antenna device that is connected to the wireless router device for establishing the second wireless communication network. ### Claim 12 (depends on 11) The vehicle control system according to claim 11, wherein the gateway router is configured to transmit the operation data to the external server by packet communication. ### Claim 13 (depends on 12) The vehicle control system according to claim 12, wherein the vehicle control device is configured to update a control application or an operating system based on data received via the gateway router. ### Claim 14 (depends on 11) The vehicle control system according to claim 11, wherein the operation data includes data indicating the operation state of the vehicle control device, data indicating the degradation state of each component of the vehicle control device, and data indicating life of each component of the vehicle control device. ### Claim 15 (depends on 11) The vehicle control system according to claim 11, wherein the wireless router device is configured to relay operation data, which have been transmitted by other wireless router devices of other vehicle control devices mounted on other railroad vehicles to the wireless router device. ### Claim 16 (depends on 11) The vehicle control system according to claim 11, wherein the antenna device includes multiple antennas that are installed on different outer peripheral surfaces of the case. ### Claim 17 A method of managing operation data for a plurality of railroad vehicles that are connected in series, comprising: collecting operation data of the railroad vehicles at a wireless router device that is housed in a case and mounted on one of the railroad vehicles; transmitting the collected operation data of the railroad vehicles from the wireless router device to a gateway router via a first wireless communication network; and transmitting the collected operation data from the gateway router to an external server via a second wireless communication network, wherein an antenna device is connected to the wireless router device and the collected operation data is transmitted from the wireless router device to the gateway router through the antenna device. ### Claim 18 (depends on 17) The method of claim 17, wherein the antenna device is installed on any of outer peripheral surfaces of the case. ### Claim 19 (depends on 17) The method of claim 17, further comprising: receiving operation data from wireless router devices of other railroad vehicles via the first wireless communication network through the antenna device. ### Claim 20 (depends on 17) The method of claim 17, further comprising: receiving operation data through the gateway router; and updating a control application or an operating system based on the operation data received through the gateway router.
