伊林思工业路由器在电梯运行远程监控系统中的应用

Category : 产品文章, 其他, 技术相关

面对近期频繁发生的电梯垂直降落,特别是被电梯夹住的恶劣事件,已经严重的威胁到了人民群众的生命财产安全。电梯系统的安全、规范和科学化管理势在必行。伊林思推出具有串口(DTU)功能的路由器,直接对接CAN-bus接口。很方便地接入到CAN BUS网络中,在不需改变原有硬件结构的前提下为CAN-bus网络提供远程无线通信接口,实现CAN-bus网络与远程计算机之间的数据通讯。这样就可以让电梯生产厂商在管理中心足不出户随时了解电梯的运行状况,便于电梯后期的维护。当电梯发生故障时或即将发生时,通过无线3G网络及时将电梯所有故障(如:电梯停电、冲顶、撞底、超速等)主动发送到管理机上 维修人员可以及时处理险情。
