Wireless multipoint temperature and humidity measuring system

Abstract

The invention discloses a wireless multipoint temperature and humidity measuring system, which comprises a wireless data acquisition system and a wireless data master supervision part, wherein the wireless data acquisition system comprises a plurality of temperature and humidity data acquisition points, acquires temperature and humidity data at a certain time interval, and packs and transmits the data through a wireless module; the whole process is controlled by a microprocessor; and a wireless module of the wireless data master supervision part receives the data, stores the data in a secure digital (SD) memory card, and transmits the data to a personal computer (PC) through a serial port to achieve the effect of monitoring in time. The wireless multipoint temperature and humidity measuring system has the advantages of simple structure, convenience for operation, low cost, high practicability, low power consumption and the like.

Description

technical field [0001] The technology relates to the field of temperature and humidity monitoring, especially a wireless intelligent temperature and humidity monitoring system. It can be used in agriculture and industry, such as temperature and humidity monitoring of granaries, vegetable greenhouses, workshops, etc. Background technique [0002] Temperature and humidity are closely related to human production and life. They are also the most common and basic process parameters in industrial production. For example, in various industries such as machinery, electronics, petroleum, and chemical industry, temperature and humidity detection and control are widely required. . And with the improvement of people's living standards, people pay more and more attention to their living environment, and the change of temperature and humidity in the air has a direct impact on the comfort and emotion of the human body, so the detection and control of temperature and humidity are very impo...

AI Technical Summary

Problems solved by technology

At present, most of the temperature and humidity detection instruments in the market are single-point measurement, and the temperature and humidity information is not transmitted in time, and the accuracy cannot meet the requirements, which is not conducive to the controller to make timely decisions according to the temperature and humidity changes. Therefore, this design and development A measurement and control product that can measure multiple points at the same time, has high real-time performance, high precision, can comprehensively process multi-point temperature and humidity information, and can perform temperature and humidity control

[0004] Generally speaking, the existing technology and the existing wired detection technology have many shortcomings, such as: complex installation and wiring, high equipment cost, poor mobility, greatly affected by environmental factors such as terrain, unable to flexibly adjust the number of monitoring points, intelligent To a certain extent, it is difficult to meet the requirements of all-weather monitoring, etc.

The patent No. 200920056505.4 proposes a temperature monitoring system, but the system adopts a wired method, which is mainly suitable for indoor use, and is not suitable for the field or places with complicated geographical conditions.
