The invention discloses an elevator outbound firmware upgrading system and method, belongs to the field of elevators, and relates to the elevator control technology, a handheld device is connected to an outbound communication bus, after the handheld device sends an outbound upgrading command request, all nodes of an elevator control system enter a silent mode, and the elevator outbound firmware is upgraded. Secondly, the handheld device requests outbound distribution information from a control system and broadcasts and issues an outbound upgrade command, all the outbound nodes receive and verify the outbound nodes to be correct, then enter a firmware upgrade state and wait for the command of the next step, in addition, the handheld device begins to poll whether all the outbound nodes enter the firmware upgrade state or not, and after the check is completed, the handheld device sends the command to the control system; starting to broadcast a firmware upgrade package, and finally confirming the integrity of the firmware package for all outbound nodes related to upgrade; according to the invention, all outbound firmware batch upgrading is realized through the existing outbound bus of the elevator control system under the condition that an outbound device is not damaged or disassembled.
本发明公开了一种电梯外呼固件升级系统及方法,属于电梯领域,涉及电梯控制技术,通过手持设备连接至外呼的通信总线,手持设备发送外呼升级命令请求后,电梯控制系统所有节点进入静默模式,其次手持设备向控制系统请求外呼分布信息,手持设备广播发布外呼升级命令,所有外呼节点接收并校验正确后进入固件升级状态,等待下一步的命令,此外,手持设备开始轮询所有外呼节点是否进入固件升级状态,检查完成后,开始广播固件升级包,最后对所有涉及升级的外呼节点进行固件包完整性的确认;本发明通过电梯控制系统现有的外呼总线,在不破坏外呼装置或拆卸的情况下实现所有外呼的固件批量升级。
