An automated system for remote energy monitoring of mobile objects with electric drives

Abstract

An approach to automation of remote energy monitoring of a mobile object with an electric drive is suggested. The approach is focused on solving the problem of generating statistics using analysis of energy consumption profiles. Structural solutions to arranging a system providing collection, transmission, and processing of measuring information from mobile object energy customers are considered. Based on the mixed implementation, a scheme of the measuring unit including a set of temperature, voltage, current, and speed sensors is developed. A data exchange scheme corresponding to the upper level of energy monitoring automation is developed. The control level in the scheme is established by JEVis local and global information systems with an open source. It is proposed to use a VIDA44M module remote telemetry and control line as a controller to collect data. The modules of the energy monitoring system can be supported by one server or distributed among several ones forming a cloud server. The data collection controllers communicate wirelessly with the server. The main calculation parameters of mobile object power supply, as well as the results of energy profile processing using hardware-in-the-loop simulations of the static and dynamic electric drive load, are considered. Based on the graphic profiles obtained by automated energy monitoring, one can assess the energy consumption of mobile objects, including public transport vehicles in a specific form, compare flow rates between similar objects, reveal faults or improper adjustment of the equipment, rank objects in power consumption, work out solutions to replace inefficient parts and mechanisms, predict power consumption, etc. As a result, power supply indices can be calculated and energy efficiency can be estimated; in addition, as energy audit of a transport company can be carried out and management decisions concerning energy efficiency can be suggested.
