The invention is suitable for the technical field of intelligent transportation, and provides a data transmission method, terminal equipment, a system and a readable storage medium. The data transmission system comprises a vehicle-mounted unit and a road side unit, the road side unit is used for acquiring a first BST message and sequentially sending a wake-up signal and the first BST message to the vehicle-mounted unit, and the first BST message sequentially carries event priorities and event information of road events; the vehicle-mounted unit is used for receiving the first BST message in response to the wake-up signal sent by the road side unit, and analyzing the first BST message in the process of receiving the first BST message, so as to control a processing module of the vehicle-mounted unit to keep a dormant state when the current electric quantity of the vehicle-mounted unit and the event priority obtained by analysis meet a dormant condition, and control the processing module of the vehicle-mounted unit to keep the dormant state when the current electric quantity of the vehicle-mounted unit and the event priority obtained by analysis meet the dormant condition. The processing module is used for analyzing event information in the first BST message. According to the embodiment of the invention, the power consumption of the vehicle-mounted unit can be reduced.
本申请适用于智能交通技术领域,提供了一种数据传输方法、终端设备、系统和可读存储介质。其中,上述数据传输系统包括车载单元和路侧单元;所述路侧单元用于获取第一BST消息,并依次向车载单元发送唤醒信号和第一BST消息,第一BST消息依次携带有道路事件的事件优先级和事件信息;车载单元用于响应于路侧单元发送的唤醒信号,接收第一BST消息,并在接收第一BST消息的过程中,对第一BST消息进行解析,以在车载单元的当前电量和解析得到的事件优先级满足休眠条件时,控制车载单元的处理模块保持休眠状态,处理模块用于解析第一BST消息中的事件信息。本申请的实施例可以降低车载单元的功耗。
