Embedded gateway, railway monitoring system adopting gateway, and railway monitoring method

Abstract

The invention provides an embedded gateway special for railways, and a railway monitoring system adopting the gateway. The embedded gateway includes an Ethernet interface, a CAN (Controller Area Network) interface, and a core translation gateway, wherein the Ethernet interface is used for communicating with a station server through Ethernet; the CAN interface is used for receiving a plurality of CAN frames complying with a CAN bus protocol from a plurality of sensor nodes arranged on a railway track through a CAN bus; the core translation gateway is used for generating a first message queue based on the priority of a task related to each CAN frame and with the received CAN frames serving as messages, and, according to a preset order in the first message queue, reading the messages and converting the messages into data messages complying with another communication protocol, so that the data messages can be sent to the station server through the Ethernet interface. The embedded gateway provided by the invention achieves high-speed, real-time and reliable status monitoring of railway devices, e.g. switch setting devices.

Description

technical field [0001] The invention relates to the technical field of signal communication, in particular to the real-time monitoring technology of railway track status. Background technique [0002] With the rapid increase of train speed, the train operation system has higher and higher requirements for railway turnout related equipment. Turnout switching equipment is an important basic equipment for train operation. Whether the equipment can work normally will directly affect the safety and efficiency of train operation. With the construction of railway passenger dedicated lines and the speed increase of existing lines, especially on large-numbered turnouts of high-speed railways, once a failure occurs, it will seriously affect the operation of the railway, and even cause catastrophic accidents. To this end, a large number of sensor arrays are arranged on the railway line, especially on the turnout, and a turnout monitoring system is established to monitor the key turnou...
