The invention belongs to the technical field of daisy chain communication, and discloses a daisy chain breakpoint recovery method and device, equipment and a storage medium. The method comprises the following steps: acquiring the connection number of front-end sampling chips in a daisy chain, and determining whether breakpoints exist in the daisy chain or not based on the connection number; when a breakpoint exists in the daisy chain, limiting the driving power based on sampling data before the breakpoint; the front-end sampling chips in the daisy chain are reconnected, so that the daisy chain returns to normal; and after the daisy chain returns to normal, obtaining overall sampling data, and based on the overall sampling data, recovering the driving power. By means of the mode, when daisy chain interference or line breaking occurs in the vehicle driving process, the position of the breakpoint can be accurately confirmed, data before the breakpoint can be obtained for power-limited driving, driving safety is guaranteed, and meanwhile the daisy chain is recovered through rapid reconnection.
本发明属于菊花链通信技术领域,公开了一种菊花链断点恢复方法、装置、设备及存储介质。该方法包括:获取菊花链中前端采样芯片的连接数量,基于所述连接数量,确定所述菊花链中是否存在断点;在所述菊花链中存在断点时,基于断点前采样数据,对行驶功率进行限制;对所述菊花链中的前端采样芯片进行重新连接,以使所述菊花链恢复正常;在所述菊花链恢复正常后,获取整体采样数据,基于所述整体采样数据,对所述行驶功率进行恢复。通过上述方式,在车辆行驶过程中,出现菊花链干扰或者断线时,可以准确确认断点位置,获取断点前的数据进行限功率行驶,保证驾驶安全,同时通过快速重连恢复菊花链。
