SalientSystems公司的StressNet系统把轨道应力检测技术与因特网的通讯能力结合起来,为铁路系统提供轨道安全性及保养状况的实时信息。采用常规的通讯设备,只有当钢轨断开,才能使电子线路切断,从而向铁路部门发出故障后的报警信号。但StressNet系统可对可能造成脱轨事故的轨道 SalientSystems’ StressNet system combines orbital stress detection with the Internet’s communications capabilities to provide rail systems with real-time information on orbital safety and maintenance. With conventional communications equipment, the electronic circuit can only be switched off when the rail is disconnected, thereby sending a signal to the railroad department after the fault. However, StressNet systems may work on rails that may cause derailment
