Use of Automatic Vehicle Monitoring (AVM) and Vehicle Health Monitoring/Diagnostic Systems by Transit Agencies

项目名称：	Use of Automatic Vehicle Monitoring (AVM) and Vehicle Health Monitoring/Diagnostic Systems by Transit Agencies
摘要：	Automatic Vehicle Monitoring (AVM) is a vehicle health diagnostic system that integrates the monitoring of an array of on-board components in order to assist in the early identification of potential mechanical problems and thus support effective maintenance. These are also sometimes referred to as multiplex vehicle health monitoring systems. Sensors monitor the performance of various engine and vehicle components and systems. This functionality takes on different forms and levels of sophistication or integration, as follows: (1) An integrated comprehensive AVM monitoring, diagnostic, and reporting system that is built into the maintenance system. AVM may be fully integrated with the on-based CAD/AVL system, or a stand-alone system. (2) Vehicle engine and component suppliers provide their own independent diagnostic systems used by maintenance departments. (3) A limited number of engine sensors integrated into the Automatic Vehicle Location (AVL) system that only provide real-time alarms of faults or critical failures (e.g., temperature, pressure, etc.). AVM can be used to identify likely mechanical failures and make maintenance more accurate or efficient. The monitoring systems provide an itemized report of all vehicle faults, allowing the maintenance department to prioritize repairs. Early identification of faults on a daily basis through expanded onboard monitoring allows the agency to respond more quickly with preventive maintenance (PM) action, which typically would not take place until the next scheduled PM interval or after a sudden breakdown occurred. The system allows direct assignment of personnel to required repair actions, thereby eliminating major costs associated with diagnostic time.
