Abstract

The invention discloses a sensor data reading and writing device and a reading and writing method thereof. The data export and system parameter configuration of most professional electronic systems often need to be realized with the help of the supporting host computer software. The invention relates to a sensor data reading and storage circuit, comprising a power supply circuit, a multiplexing circuit, a TF card circuit, a TF card reading circuit and a main control circuit. The TF card reading circuit includes a card reader chip and a USB socket. The multiplexing circuit includes a multiplexing chip. By setting the multiplexing circuit, the invention can realize the switching connection between the TF card, the main control chip and the host computer, thereby simplifying the reading process of sensor data and the configuration process of the sensor. The data selection end of the multiplexing chip in the present invention is connected to the TF card reading circuit. Therefore, when the TF card reading circuit is powered on, the TF card will be automatically connected to the host computer, which simplifies the process of connecting the TF card to the host computer.
