Track traffic synthetic monitoring system and method

Abstract

The invention discloses a rail traffic comprehensive monitoring system and a method thereof, comprising a collecting platform, a comprehensive monitoring supporting platform and a monitoring control module which are sequentially connected through application interfaces. The invention also comprises a maintenance management module which is connected with the comprehensive monitoring supporting platform through the application interface. The method comprises online detection, filtration and malfunction grade judgement. The disposal is carried out according to different grades and different situations; a preparedness disposal is carried out if the disposal belongs to the first grade and, for the residual disposals, the maintenance strategy is determined and the expert database sub-module is updated according to the decision of experts; the equipment which is required to be maintained at once is maintained or waits to be maintained; a nominal disposal is firstly carried out during the maintenance and then malfunctions are isolated; the maintenance result is detected finally and the malfunction and maintenance condition are recorded. The invention can effectively reflects the healthy condition of equipment and gives out maintenance strategy in the comprehensive monitoring system, which leads the maintenance and operation scheduling to be integrated for management, implements high integration, transparence and informationization of maintenance operation, and effectively reduces construction cost.

Description

technical field [0001] The invention relates to a rail transit comprehensive monitoring system and method. technical background [0002] Generally, rail transit includes three operating systems: driving system, operating service system and maintenance system. The traffic system is mainly based on the signal system to ensure traffic safety and personal safety; the operation service system is mainly based on the comprehensive monitoring system to meet the requirements of operation dispatching and passenger service; the maintenance system is mainly based on the equipment maintenance management system. Provide basic guarantees for operations. [0003] The comprehensive monitoring system of rail transit is generally composed of a data acquisition platform, a comprehensive monitoring support platform and some upper application modules, which are used to realize the monitoring and dispatching of professional systems such as power supply system, environmental control system, fire a...

AI Technical Summary

Problems solved by technology

[0006] (1) The maintenance department urgently needs advanced functions such as early warning of equipment failure to effectively reduce the failure rate of equipment and ensure driving safety, but the currently commonly used planned maintenance and failure maintenance cannot fully meet this requirement

For example, for the key electromechanical equipment of rail transit, if there are too many planned maintenance times and too frequent equipment replacement, it will waste time, manpower and material resources, and even reduce the reliability of the equipment and shorten the service life of the equipment due to too many times of equipment disassembly and assembly. Service life; if it is too small, the integrity rate of the equipment cannot be well guaranteed, and equipment with hidden dangers may break down during operation and cause serious accidents

Fault maintenance is a passive maintenance method, which can neither guarantee the normal use of the equipment nor the normal operation order

[0007] (2) Since the equipment maintenance management system cannot share the data collected by the integrated monitoring system, the function of the equipment maintenance management system is limited to the statistics and analysis of equipment fixed information, which cannot reflect the current health status of the equipment in time, and cannot predict the potential failure of the equipment

[0008] (3) If a dedicated data collection platform is built for the equipment maintenance and management system, not only will there be a problem of repeated construction, but also a large amount of capital investment will be required. Therefore, the existing equipment maintenance and management systems do not include a dedicated data collection platform

[0009] (4) Since the comprehensive monitoring system has multiple data interface relationships with power monitoring, environmental control, fire alarm and other systems, the equipment maintenance system also has similar interface relationships with these systems, making the existing interfaces repetitive and large in number. The type is complex, which increases the difficulty of construction
