The invention relates to a power conversion cabinet data transmission method and system for local area network, which are applied to a power conversion cabinet system. The power conversion cabinet system comprises a plurality of power conversion cabinets, and the distance between the plurality of power conversion cabinets is within a preset distance range. The method comprises the steps of, S1, in the working or battery replacing process of the multiple battery replacing cabinets, detecting the networking states of the battery replacing cabinets in real time, and judging whether data transmission conditions are met or not; if yes, executing the step S2; if not, executing the step S3; S2, keeping power conversion cabinet data transmission between the power conversion cabinets meeting the data transmission conditions and the cloud platform ; and S3, completing data transmission between the power conversion cabinets which do not meet the data transmission condition and the cloud platform through specified power conversion cabinets in the power conversion cabinets which meet the data transmission condition by the power conversion cabinets which do not meet the data transmission condition. According to the invention, data transmission with the cloud platform can be ensured without adding any communication module after the network is abnormal, the online reliability is enhanced, the implementation is simple and easy to operate, and the stability and reliability of battery replacement are ensured.

    本发明涉及一种局域组网的换电柜数据传输方法及系统,应用于换电柜系统中,换电柜系统:多台换电柜,多台换电柜之间的距离在预设距离范围内;方法包括:步骤S1、多台换电柜在工作或者换电过程中,实时检测自身的联网状态并判断是否满足传输数据条件;若是,执行步骤S2;若否,执行步骤S3;步骤S2、满足传输数据条件的换电柜与云平台保持换电柜数据传输;步骤S3、不满足传输数据条件的换电柜通过满足传输数据条件的换电柜中的指定换电柜完成不满足传输数据条件的换电柜与云平台的数据传输。本发明不需要增加任何通讯模块即可保证在网络异常后仍可与云平台保持数据传输,在线可靠性增强,且实施简单易操作,保证了换电的稳定性和可靠性。
