As can be seen from the above transmission process, the battery information collecting apparatus 10 may store and transmit data in pages, and continue to transmit the data next time after the transmission fails. That is to say, the battery information collecting device 10 of the present invention emphasizes real-time data collection and transmission of the single battery, and can store the data when transmission fails due to transmission and sending without a relay device, and wait for next sending, thereby avoiding data loss. The battery information collecting device 10 of the present invention emphasizes a data caching mechanism when the transfer device is temporarily not available and a data recovery transmission mechanism for accessing the transfer device.
Further, the battery information acquisition method further comprises the following steps:
s130, the terminal device 40 sends a control instruction to the server 30, the server 30 sends the control instruction to the relay module 20, the relay module 20 sends the control instruction to the battery information acquisition device 10, and the battery information acquisition device 10 executes corresponding operation according to the control instruction.
Specifically, the terminal device 40 may control the battery information collecting apparatus 10 to perform corresponding operations, for example, the terminal device 40 calls data of a certain time from the battery information collecting apparatus 10.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
