Embodiment Construction

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like figure 1 As shown, a sensor data reading and writing device includes a power supply circuit I, a multiplexing circuit II, a TF card circuit III, a TF card reading circuit IV, an RTC clock circuit V and a main control circuit VI. Power supply circuit I supplies power for multiplexing circuit II, TF card circuit III, RTC clock circuit V and main control circuit VI. A TF card is set on the TF card circuit III. The TF card circuit III is connected with the multiplexing circuit II. The multiplexing circuit II realizes the switching between the TF card circuit III, the TF card reading circuit IV and the main control circuit VI through the multiplexing chip. The RTC clock circuit Ⅴ provides the clock signal for the main control circuit Ⅵ.

[0028] like figure 2As shown, the power supply circuit includes a switching power supply chip U1. The model of the switc...

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.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a sensor data reading and writing device and a reading and writing method thereof. Background technique [0002] Data storage and system parameter configuration are important components of various embedded electronic systems. 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 development of the supporting dedicated host computer software requires a certain amount of energy and financial resources, and the inconvenience of the host computer will lead to inconvenience for users. Therefore, it is particularly important to develop a data storage and parameter configuration circuit with good versatility, strong operability and convenient use in the design of electronic systems. SUMMARY OF THE INVENTION [0003] The purpose of the present in...
