Embodiment 1

[0024] like figure 2 As shown, the CPU of the main control module 1 adopts the AT89S52 processor chip of ATMEL Company to coordinate and control the work of each module connected to it. AIO module 7 includes 8 analog input interfaces, composed of ICL7109 chip, MAX308 chip and peripheral circuit of front-end filter, constitutes a device acquisition module, directly connected to the external terminal on the micro-cabinet of the rolling stock equipment room, and collects the operation of the main components of the rolling stock parameter. UART module 3 uses known RS-485 serial interface standard communication, is made up of UART interface and MAX485E chip integrated by AT89S52 chip, and known RS-485 peripheral circuit, communicates with other on-board equipment of rolling stock, receives the locomotive collected by other equipment Basic operating information of the vehicle. Ethernet module 4 supports standard Ethernet communication protocol, and is composed of ENC28J60 network...

Abstract

The invention discloses a rolling stock data acquisition device based on an Ethernet, which comprises a master control module, an Ethernet module, a UART (universal asynchronous receiver transmitter) module, an A / D (analog / digital) module, an AIO (asynchronous input / output) module, an MVB (multifunction vehicle bus) module, a circuit protection module and a working power module. The vehicular Ethernet with an M12 interface is used for large volume data conversion and transmission, and the data acquisition device can receive various standard sensor signals and RS485 and MVB data. By the aid of the rolling stock data acquisition device, state and failure information of various components and equipment on trains can be effectively acquired, converted and integrated in various network control environments of various rolling stocks, and accordingly driving safety of the rolling stocks is reliably guaranteed.

Description

technical field [0001] The invention relates to a vehicle-mounted data acquisition device, in particular to an Ethernet-based rolling stock data acquisition device. Background technique [0002] Railway transportation is one of the main modes of transportation in my country. With the continuous expansion of railway coverage, there are higher requirements for the stability of locomotive equipment. With the rapid speed increase of my country's railways several times, higher requirements have been put forward for the safe, reliable and efficient operation of locomotives and high-speed trains, and problems such as backward maintenance methods and insufficient maintenance capabilities of locomotives and high-speed trains have gradually been exposed, and the solution to this problem The consensus is to collect the operating parameters of the main components and fault-prone parts of the locomotive and high-speed trains in real time, and transmit these data to the ground data center ...
