Remote multi-point temperature and humidity data acquisition system based on single-chip microcomputer

Abstract

The invention provides a remote multi-point temperature and humidity data acquisition system based on a single-chip microcomputer. The remote multi-point temperature and humidity data acquisition system comprises a controller module, a display module, a power supply module, a temperature and humidity acquisition module, an alarm module and a communication module, wherein the controller module takes an STC89C52 single chip microcomputer as a control core; and the display module is composed of an LCD liquid crystal display screen with a 12846 dot matrix and four double-color light-emitting diodes. The remote multi-point temperature and humidity data acquisition system adopts an external clock chip, and uses a battery for supplying power, so that related information of a clock can be stored even under the condition of power failure.

Description

[0002] With the continuous development of computers, single-chip microcomputers are widely used in the field of intelligent control as an important branch. The advantages of high integration, small size, high reliability, and low voltage of single-chip microcomputers can be used as core control components to control the operation of the entire system. Temperature and humidity monitoring and data collection and feedback are important parts of modern agricultural technology. Agricultural production can be adjusted by monitoring the temperature and humidity of the soil and the environment to obtain better yields and economic benefits. There are various types of existing data collection systems , but there are still some problems in practical use. For example, the built-in timer often has timing deviation and data is easily lost, especially when communicating with GSM modules. Although it does not affect the functions of the host computer and the alarm module, However, due to the existence of such problems, there is a deviation in the communication between the entire data acquisition system and the mobile phone monitoring terminal, and the actual use effect is poor. The administrator can only rely on the host computer for information interaction, which is not convenient. Therefore, the present invention designs a new temperature and humidity Data acquisition system, optimize the system from multiple angles to solve the above problems
