Design And Development Of Data Acquisition And Distribution System Based On WeChat Hardware

Today we are in a rapidly developing information age.With the rapid development of data analysis,data mining and other technologies,the value of various types of data in production and life becomes higher and higher,and the research on data acquisition systems has become increasingly important.In recent years,with the rapid development of Internet of Things technology,smart hardware development platforms have been mentioned more.Smart hardware platform provides new options for IoT solutions.The WeChat hardware platform is also launched under this background,which greatly reduces the difficulty of hardware devices accessing the Internet,simplifies the communication process between people and things,and things,and has strong openness,mature technology,and a wide audience advantage.The data acquisition and distribution system based on WeChat hardware platform designed in this paper aims to provide new ways for data collection and distribution,and promote the practical,universal and intelligent development of data collection.This paper takes temperature and humidity collection as an example to introduce the realization of data collection function of the system,and takes exploring the relationship between temperature and humidity and indoor crowd density as an example to introduce the realization of data release function of the system.The system combines the advantages of the WeChat hardware platform,can use the WeChat public number to view the collected data,publish data,and control the number of acquisition end devices.It has the advantages of low access to the acquisition equipment,simple control of the acquisition equipment,and convenient data viewing.The traditional method of monitoring crowd density basically belongs to the direction of video or image processing technology.Although the technology is relatively mature,it requires video surveillance,photographing or wiring,and the monitoring cost is relatively high.This article has changed the traditional way of estimating the indoor population density,using human activities will affect the characteristics of indoor temperature and humidity,put forward the use of temperature and humidity to reflect the indoor population density and reduce the monitoring costs.The system involves two public numbers.One is used to bind equipment,control data collection and distribution,called administrator public number,and the other is to receive released data,which is called general public number.The user enters the administrator's public number through the binding collection device and can actively publish the data and publish the data to the general public number so that all those who are concerned about the public number can receive the data information.The advantage of this is that all people concerned about the general public number can receive the data they care about,and distinguish the user's authority.The person who binds the device can control the data collection and distribution,and only those who are concerned with the public number.Only data can be received to ensure the system's practicality and data security.The system architecture of this article includes hardware and software parts,which realizes the separation of data acquisition and data processing hardware and software.Hardware development based on DA14580 development board,mainly responsible for data acquisition.The software is based on Alibaba Cloud,which is mainly responsible for data analysis and processing.Service modules,logic processing modules,data processing modules,and database modules are designed.In addition to the necessary program burning in the hardware device,some of the logic processing involved in the server program,with the advantages of easy expansion.In order to test the data acquisition and distribution system,we collected indoor temperature and humidity data,and established a relationship model between the temperature and humidity data and the indoor population density,using the collected temperature and humidity data to achieve the purpose of monitoring indoor crowd density,and Temperature and humidity data and crowd density information are issued to users of general public numbers.The test results show that the system designed in this paper can work on data collection normally and stably,and can accurately estimate the indoor population density,and can push the data to the public number for publication,which is convenient for users to view.
