Many switch cabinets are at work or trade the electric in-process, and the networking state of real-time detection self and judge whether satisfy the transmission data condition and include: the main power switching cabinet detects the networking state of the main power switching cabinet in real time and sends a networking state detection instruction to the plurality of sub power switching cabinets in real time; the method comprises the steps that a plurality of sub power switching cabinets detect the networking state of the sub power switching cabinets in real time, and send state detection results to a main power switching cabinet according to networking state detection instructions; and the main power switching cabinet judges whether the main power switching cabinet and the plurality of sub power switching cabinets meet the data transmission condition or not according to the networking state of the main power switching cabinet and the state detection result sent by the plurality of sub power switching cabinets. Furthermore, the plurality of sub-power-switching cabinets interact respective state detection results in real time, and whether the sub-power-switching cabinets meet data transmission conditions or not is judged according to the respective state detection results.
In the embodiment, the networking state detection and judgment are carried out on a plurality of power change cabinets in the form of a main power change cabinet and a secondary power change cabinet. Specifically, any one of the multiple power switching cabinets is set as a main power switching cabinet, the rest of the multiple power switching cabinets are set as sub power switching cabinets, when the network state is detected, the main power switching cabinet detects the networking state of the main power switching cabinet in real time, a networking state detection instruction is sent to the multiple sub power switching cabinets in real time, the multiple sub power switching cabinets detect the networking state of the multiple sub power switching cabinets in real time, a state detection result of the main power switching cabinet is returned to the main power switching cabinet at regular time, the main power switching cabinet judges the transmission data conditions according to the networking state of the main power switching cabinet and the state detection result returned by the multiple sub power switching cabinets, and therefore the transmission data conditions of the sub power switching cabinets and the main power switching cabinet are determined, and the transmission data conditions of the main power switching cabinet and the transmission data conditions of the sub power switching cabinets are sent to the sub power switching cabinets in real time. It should be noted that, in this embodiment, communication may also be performed between the sub power switching cabinets, so that when any one power switching cabinet network is abnormal, data may be transmitted through other power switching cabinets.
Or, in some other embodiments, the detecting the networking state of the plurality of power switching cabinets in real time and judging whether the transmission data condition is met includes: and the plurality of power change cabinets detect the networking states of the power change cabinets in real time, and judge whether the power change cabinets meet the data transmission conditions according to respective state detection results. The networking state of a plurality of power switching cabinets within a preset distance range is detected in real time, whether the power switching cabinets meet the data transmission condition is judged, and the real-time data transmission conditions of other power switching cabinets can be obtained, so that data can be transmitted through other power switching cabinets when any power switching cabinet network is abnormal.
Optionally, in the embodiment of the present invention, the power exchange cabinet is designated as the power exchange cabinet with the strongest signal transmission in the power exchange cabinets meeting the data transmission condition.
A, B, C, D four electricity-changing cabinets are arranged in the preset distance range, and after the installation is finished, the four battery replacing cabinets can complete local area networking in a wired or wireless mode (certainly, local area networking can also be carried out in the working process or the battery replacing process in real time), after local area networking is finished, in the working process or the power exchange process, each power exchange cabinet detects the networking state of the power exchange cabinet in real time and judges the data transmission condition of the power exchange cabinet (namely whether the power exchange cabinet can be networked with a cloud platform or not, if the power exchange cabinet can be networked with the cloud platform, the power exchange cabinet is judged to meet the data transmission condition, if the power exchange cabinet is disconnected from the cloud platform, the power exchange cabinet is judged not to meet the data transmission condition), and feeds the data transmission condition of the power exchange cabinet back to other power exchange cabinets, therefore, when any one of the A, B, C, D has a network fault, data interaction with the cloud platform can be performed through other stations. For example, in the power exchange process, network abnormality occurs, and normal data interaction cannot be performed with the cloud platform, at this time, the power exchange cabinet a selects one with the strongest transmission signal from B, C, D power exchange cabinets (set as the power exchange cabinet C), the power exchange cabinet C is the designated power exchange cabinet, and data transmission of the power exchange cabinet a is completed through the power exchange cabinet C, that is, the power exchange cabinet a transmits data to the power exchange cabinet C, and then the power exchange cabinet C transmits the data to the cloud platform, after the cloud platform performs related data processing, the data is returned to the power exchange cabinet C, and is returned to the power exchange cabinet a through the power exchange cabinet C, so that when the network abnormality of the power exchange cabinet a is completed, data interaction with the cloud platform is continuously completed through the power exchange cabinet C, and reliability and continuity of data transmission of the power exchange cabinet a are ensured.
Further, in the embodiment of the present invention, the battery swapping cabinet data includes: equipment data of the power switching cabinet and information data in the power switching process.
Wherein, the equipment data of the cabinet of changing electricity includes: any one or more of hardware information data, alarm data, traffic data, and maintenance data.
