Road spacing speed display system based on double Ethernet

Abstract

The invention discloses a road spacing speed display system based on double Ethernet. Two independent data information Ethernet ports are formed in a double Ethernet meter. The double Ethernet meter is electrically connected with a W5500 chip through the data information Ethernet ports. An information transformation module is mounted on the W5500 chip. The output end of the W5500 chip is electrically connected with the input end of an ARM chip. The output end of the ARM chip is electrically connected with the input end of a stepping motor drive meter through a VI transformation circuit. According to the road spacing speed display system based on the double Ethernet, the double Ethernet is adopted to conduct network communication, so that the communication speed is increased, and the communication quality is improved; the datum amount of simultaneous transmission is large, and through mutual collaboration and standby application between double Ethernet channels, the situation that an network fault occurs so that data cannot be received, and normal rail travelling is affected can be effectively prevented; and the double Ethernet has strong network fault treatment capacity, so that the road spacing speed display system is steadier.

Description

technical field [0001] The invention relates to the technical field of road distance and speed display systems, in particular to a road distance and speed display system based on dual Ethernet. Background technique [0002] The intelligent transportation system is the development direction of the future transportation system. It is a kind of system established by effectively integrating advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground traffic management system. It is a real-time, accurate and efficient comprehensive traffic management system that plays a role in a wide range and in all directions. The intelligent traffic system is based on the traffic flow data of the road network to initialize the timing and control of traffic signals, and at the same time according to real-time traffic flow conditions , adjust the timing plan in real time to realize ...

Problems solved by technology

[0003] At present, the driver's cab of rail transit vehicles is generally equipped with a special display screen for monitoring and displaying various real-time data of locomotive operation, such as speed, voltage, current, pressure and other index parameters. Channels for data transmission, resulting in data collection that cannot be sent to multiple display screens at the same time, affecting data comparison and reference, and the communication performance of the communication method is poor, the communication speed is slow, and the amount of communication data is small, resulting in unsafe driving of rail transit. At the same time, when the single network distance shows a fault, it cannot be used normally, affecting normal rail traffic
