Embodiments of the present invention provide a method and system for processing locomotive data, a locomotive and a server, which belong to the field of transportation and communication. The method includes two aspects, one is the method executed by the locomotive, and the other is the method executed by the server. The method performed by the locomotive includes: collecting information of the locomotive, wherein the information includes basic information and / or operation information of the locomotive; collecting grid voltage and current of the locomotive; calculating forward active power and reverse feedback power of the locomotive according to the grid voltage and current ; Transmitting information and energy consumption data to the server, so that the server processes the information and energy consumption data, wherein the energy consumption data includes at least one of the following: network voltage, current, forward active power and reverse feedback power. In this way, the data of the locomotive can be acquired remotely, real-time monitoring of whether the network voltage of the locomotive is abnormal, and the electric energy fed back by the locomotive can be effectively obtained.

The invention discloses an optical call column for a railway section to solve the problem of point-to-multipoint optical communication transmission access in the railway section. An upper end of a hollow column (1) is connected with a base plate; an optical cable or an electric cable enters a cavity through the hollow column (1) and is divided into an optical fiber bundle tube or an electric cable core wire; and the optical fiber bundle tube or the electric cable core wire is fixedly connected with a fixing bracket (7) on the base plate (2). The optical fiber bundle tube enters an optical fiber lead-in welding layout unit (6) and is connected with the same; upper and lower link through fiber pigtails led out of the optical fiber lead-in welding distribution unit (6) are connected in series with an optical adapter (8) on an optical fiber coupling divider unit (5); the optical adaptor (8) is connected with an optical splitter (9) which is connected with an optical transceiver interface (10) of section optical far-end equipment (4); a power interface (11) and a telephone interface (22) of the section optical far-end equipment (4), an Ethernet port (23) and an E1 interface (12) are connected with a distribution port plate (13) on the base plate (2); and the electric cable core wire is connected with the distribution port plate (13) on the base plate (2).

The invention discloses a power grid integrated information remote access method. The method includes allowing a local control center to transmit a power grid integrated information remote access service request to a remote control center, allowing the remote control center to make decisions according to the remote access service request and return image files to the local control center, and allowing the local control center to analyze the image files and transmit an image data service request to the remote control center; allowing the remote control center to query real-time data indexes in a power grid integrated information database according to the content of the image data service request, acquiring the power grid integrated information data according to the indexes, and transmitting the power grid integrated information data to the local control center after power grid integrated information combination; allowing the local control center to receive and display the power grid integrated information data. Thus, the share and exchange of the power grid integrated information of different control centers can be implemented, and the practicality level of power grid integrated information monitoring is raised effectively.

The invention provides a remote access method and system for a group intranet. The remote access method for the group intranet comprises the steps that when a group intranet user migrates from a source cell of the group intranet to a remote target cell, the target cell receives a remote access request sent by the user, wherein each of the source cell and the target cell comprises an HSS (home subscriber server), and the data of the HSS of the source cell is synchronous with that of the HSS of the target cell; the target cell confirms that user data information of the user is stored in the HSS of the target cell; and the target cell allows the user to access the target cell remotely according to the user data information. Through the group intranet remote access method and system, remote access of industrial group intranet can be achieved simply and effectively for the user.

The invention discloses a wireless public network communication method with security protection in a power system, and relates to a wireless public network communication method. In order to solve the problem that attack of an external network to a substation cannot resisted because identity authentication and data encryption are not carried out in data communication between a master station and the substation when wireless public network communication is used at present, the method comprises the following steps of: transmitting data packets of n groups of integrated automatic equipment or remote terminal units (RTU) to corresponding substation security gateways through serial communication ports; signing and encrypting the received data packets by each substation security gateway; transmitting the data packets to a master station security gateway by using a wireless public network; de-signing and decrypting the received data packets by the master station security gateway; transmitting the data packets to a central wireless gateway system; and transmitting the data packets to a front-end processor of an event management system (EMS) by using a serial RS-232 communication interface through the central wireless gateway system. The method is used for the wireless public network communication in the power system.
