Remote diagnosis system for existing track engineering machinery

Abstract

The invention discloses a remote diagnosis system for existing track engineering machinery. The remote diagnosis system comprises a vehicle-mounted host machine, a switch device, a front end analog quantity acquisition board, a multipath analog quantity acquisition board, a program control motherboard, at least two vehicle driving monitoring digital quantity acquisition modules and at least two vehicle driving monitoring analog quantity acquisition modules. Data interaction is conducted between the vehicle-mounted host machine and a third party device via the switch device; the front end analog quantity acquisition board, the multipath analog quantity acquisition board and the program control motherboard transmit collected operating condition data of the track engineering machinery to the vehicle-mounted host machine via an on-site bus. The vehicle driving monitoring digital quantity acquisition modules and the vehicle driving monitoring analog quantity acquisition modules transmit collected vehicle driving safety monitoring data of the track engineering machinery to the vehicle-mounted host machine. The remote diagnosis system can solve technical problems of difficult existing track engineering machinery information acquisition monitoring, low trouble-shooting efficiency, difficult on-site management, and difficult vehicle-mounted equipment installation and wire arrangement.

Description

technical field [0001] The invention relates to the field of railway engineering, in particular to a remote diagnosis system applied to existing track engineering machinery.
