The function configuration module mainly has three main functions of time synchronization, sampling interval setting and memory cleaning, and before each test, the time of the transmitting and receiving circuit boards is synchronized with the ground standard time through the time synchronization function so as to compare with logging related data during data processing and judge the test effect; the memory of the transmitting and receiving circuit board is limited in memory space, the number of signal data points which can be stored is limited, the test requirements of different time periods can be met by setting the sampling interval of the receiving circuit board, the same number of data points are stored, the larger the sampling time interval is, the longer the time period which can be tested is, and the test time period = the number of the stored data points multiplied by the sampling interval; after the test is completed, the memory cleaning function can be used for cleaning the memory of the transmitting and receiving circuit board memories, and more memory space is released, so that the next test is facilitated.
The data reading module is mainly used for reading data points in the memory of the transmitting and receiving circuit board into a computer, the format is Excel, and main contents comprise data point serial numbers, acquisition time (xx, min, xx and sec when xx is the date of xx, xx and xx) and battery voltage data.
The data playback module can replay the read data (Excel format) and can display the number of data points, time and battery voltage signals.
The data display module can monitor the transmitted or received battery voltage data in real time, draw a curve for display, and is mainly used for testing the transmitting or receiving circuit board before experiments, and the curve is stable and continuous, so that the transmitting or receiving circuit board works normally.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
