WARNSS (Wireless Autonomous Rail Networked Sensing System)

现有的Perpetuum列车传感器系统使用振动能量采集器（VEH）为振动传感器、电子设备和通信设备供电，这些设备可以监控轴承、车轮和轨道的健康状况。它记录振动数据并通过数据集中器无线传输，数据集中器使用GSM网络传输到列车外。该系统运行良好，能量采集器为列车运营商提供了独特的支持技术，使其能够在25年的使用寿命内做出明智的维护决策。现有的能量采集器通常为系统产生足够的电力，并使用电容器进行能量存储。随着TSB资助的项目EQUIPGYMAN的完成，这种情况得到了进一步改善，该项目提高了电源管理电子设备的效率。系统现在有能量可用于通过监控其他设备（例如变速箱、电机、制动器）来提高其能力。该项目将使Perpetuum的传感器系统能够提供全面的数据，从而能够对更广泛的设备进行明智的维护，并为列车运营商节省大量成本。

The existing Perpetuum train sensor system uses vibration energy harvesters (VEH) to power a vibration sensor, electronics and communications that can monitor the health of bearings, wheels and the track. It records vibration data and transmits wirelessly via a data concentrator that transmits off the train using the GSM network. The system performs very well and the energy harvesters provides a unique enabling technology for train operators to make informed maintenance decisions over a lifetime of 25 years. The existing energy harvester typically generates more than sufficient power for the system and uses capacitors for energy storage. The situation has further improved with the recent completion of the TSB funded project ENERGYMAN which has increased the efficiency of the power management electronics. The system now has energy available to improve its capability by monitoring further equipment (e.g. gearboxes, motors, brakes). This project will enable Perpetuum’s sensor system to provide comprehensive data that enables informed maintenance of a much wider range of equipment and provide considerable cost savings to the train operator.
