Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] refer to figure 1 , a multivariate data acquisition system based on an embedded system, including:

[0044]Matrix keyboard, according to the matrix keyboard DataSheet, when the button is not pressed, the output is high level, when the button is pressed (such as button J1), if the PP2 pin (ie ROW1_IN) input high level, then PD0 The pin (COL1_OUT) output is also high level; if the PP2 pin inputs low level, the PD0 pin output is also low level. By selecting a row to set the low level and scanning the four output terminals, it is possible to know which button in the row is pressed.

[0045] In the actual situation, there is a certain vibration when the button is pressed, and the delay debounce algorithm is adopted in the present invention: when the button is pressed, the delay is advanced, and then it is detected whether the button is still in the pressed state ,...

Abstract

The invention relates to a multivariate data acquisition system based on an embedded system. The system comprises a control chip, a matrix keyboard, a TFT touch screen, a triaxial accelerometer, a rocker, a ZigBee sending module and a ZigBee receiving module; the matrix keyboard, the TFT touch screen, the triaxial accelerometer and the rocker are all connected with the control chip; the control chip is connected with the ZigBee sending module; the ZigBee sending module is in communication connection with the ZigBee receiving module; the ZigBee receiving module is connected with a PC end. The invention provides the multivariate data acquisition system based on the embedded system, which is rich in data type and good in applicability.

Description

technical field [0001] The invention belongs to the field of embedded data acquisition and communication, and relates to single-chip microcomputer embedded ZigBee communication technology, PC terminal serial port communication technology, multi-sensor data acquisition system design and other technologies. Background technique [0002] A sensor refers to "a device or device that can sense a specified measured value and convert it into a usable signal according to a certain rule, usually consisting of a sensitive element and a conversion element." A sensor is a detection device that can feel the measured information, and can convert the detected information into electrical signals or other required forms of information output according to certain rules, so as to meet the needs of information transmission, processing, storage, display, recording and control requirements. It is the first link to realize automatic detection and automatic control. [0003] Sensor technology is n...
