The invention relates to the technical field of road traffic, in particular to a C-V2X vehicle-road cooperation system roadside equipment information configuration method. Roadside unit equipment information, map information and the like can be configured through a JSON format configuration file, remote configuration is performed through an MQTT protocol in a 4G mode, and platform management is realized. The method comprises the following steps that: S1, a cloud platform is built, an MQTT service is started and a corresponding configuration message theme is subscribed; S2, after a roadside unit is started, the MQTT service is started, and a corresponding configuration message theme is subscribed at the same time; S3, roadside equipment needing to be configured is connected through the cloud platform, configuration information is issued to a corresponding theme through the MQTT service, and the information is broadcast to the roadside equipment giving the corresponding theme; S4, the roadside equipment reports and issues data to the cloud platform through a 4G module; and S5, after receiving the data issued by the cloud platform, the roadside equipment writes the configuration information into a configuration file of the roadside equipment after data analysis, so that the configuration of the roadside equipment is modified.
本发明涉及道路交通的技术领域,特别是涉及C‑V2X车路协同系统路侧设备信息配置的方法,可以通过JSON格式配置文件配置路侧单元设备信息和地图信息等,用4G方式通过MQTT协议进行远程配置,实现平台化管理;包括以下步骤:S1、搭建云平台,开启MQTT服务并订阅相应的配置消息主题;S2、路侧单元启动后同时会启动MQTT服务并订阅相应的配置消息主题;S3、通过云平台连接需要配置的路侧设备,将配置信息通过MQTT服务发布到相应的主题上,并且将信息广播给定相应主题的路侧设备;S4、路侧设备通过4G模块,实现与云平台数据的上报和下发;S5、路侧设备收到云平台下发的数据后,经过数据解析后将配置信息写入到路测设备本身的配置文件中,从而实现修改路侧设备的配置。
