Abstract

The invention discloses a collection device based on a single-chip microcomputer and a SIM900A. The device is composed of four subsystem modules, namely, a collection system module, a single-chip microcomputer minimum system module, a wireless transmit-receive module and a liquid crystal display module. The collection system module mainly comprises a first temperature sensor and a second simulation-type humidity sensor, and is used for completing front end humiture sampling. The wireless transmit-receive module takes the SIM900A as a core and is used for sending a humiture signal to an assigned IP or equipment. The collection device is good in stability and reliability and has a high utility value and an application prospect. The collection device is free from restrictions of landforms and common environments, is strong in applicability, and can meet requirements for environmental parameter collection in remote regions and in complex conditions that wiring is difficult and the like.

Description

technical field [0001] The present invention relates to the field of environmental data collection and wireless transmission and reception, more specifically, the present invention relates to a collection device based on single-chip microcomputer and SIM900A. Background technique [0002] In recent years, with the rapid development of electronic technology and communication technology, wireless communication has been widely used in many fields. The construction in remote areas is booming day by day, and it is inevitable to collect demand data such as temperature and humidity in remote areas during the construction process. At present, our country still lacks the collection technology of environmental parameters under complex working conditions such as remote areas and difficult wiring, which greatly hinders the country's construction of remote areas. [0003] Chinese Patent No. ZL 200620012855.7 discloses a single bus temperature and humidity data acquisition transmitter. T...
