Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] The following takes the digital sensor MAG3110 as an example to provide 12 MAG3110 array connections and data readout methods. The MAG3110 is an I 2 For the sensors of the C bus, all the sensors can be set to the same working mode in a unified way of reading and writing in the array, such as the continuous measurement working mode. In this working mode, all sensors have the same data output format and output timing under a given timing clock signal. The microcontroller for reading and writing the sensor may be a single-chip microcomputer, ARM, FFPGA, CPLD, etc. This embodiment uses STM32f407 as an example for illustration.

[0019] Sensor array arrangement and connection method:

[0020] The 12 sensors MAG3110 are divided into 3 rows × 4 columns and distributed in a rectangular array. The sensors are distributed as follows: figure 1 ...

Abstract

The invention relates to a connection method for a digital sensor array. Multiple digital sensors adopt array distribution, rows and columns of an array are clock lines or data lines, a clock line SCLof each sensor in the array is connected to a clock line SCLi of the array, and i is equal to 1-M; a data input / output line SDA of each sensor in the array is connected to a data line SDAj of the array, and j is equal to 1-N; an IO pin of a micro controller is connected to the clock line and the data line of the sensor array; and the micro controller drives the clock line of the digital sensor array and reads in data of all the sensors in the array by virtue of the data line of the array.

Description

technical field [0001] The present invention relates to a class of digital sensors. Background technique [0002] Sensors are the main ways and means for people in modern society to obtain information in the fields of nature and production. In modern industrial production, especially in the automated production process, various sensors are required to obtain various parameter information in the production process; in the Internet of Things, various sensors are used to measure or perceive various information in the surrounding environment. Sensors are generally divided into analog sensors and digital sensors. The digital sensor is a sensor that passes the traditional analog sensor through the A / D conversion module to make the output signal a digital quantity. The advantage of the digital sensor is that the application circuit structure is simple, and the direct digital output is convenient for direct input into the computer. Nowadays, more digital sensors communicate with t...
