Wireless temperature and humidity acquisition system

Abstract

The invention discloses a wireless temperature and humidity acquisition system, which is characterized by comprising a host computer, a slave computer and a wireless module, wherein the host computeris used for data processing and control output; the slave computer is used for temperature and humidity data acquisition and data output; and the wireless module is used for establishing communicationconnection between the host computer and the slave computer, the transmitting terminal enters a response state after transmitting data to the receiving terminal, and the receiving terminal returns aresponse signal if receiving the data packet of the transmitting terminal; otherwise, the receiving terminal does not return a response signal, and the transmitting terminal retransmits the unsuccessful data packet at regular time until the limited number of times is reached. The wireless temperature and humidity acquisition system adopts a structure form of the host-slave computers, the data transmission is implemented through the wireless module, the probability of congestion during data transmission is greatly reduced through adding a data handshaking mechanism, and the problems of line interference and data distortion are avoided; and meanwhile, the wireless temperature and humidity acquisition system adopts a mode that the host computer controls the process and the slave computer performs acquisition, so that the data processing ability is enhanced.

Description

technical field [0001] The invention relates to the technical field of temperature and humidity collection, in particular to a wireless temperature and humidity collection system. Background technique [0002] With the advancement of science and technology and the development of society, people pay more and more attention to environmental conditions in life and production. As the two basic environmental elements in the daily life of human beings, temperature and humidity are closely related to our production and life. The most important measurement parameters, so real-time monitoring of temperature and humidity is very necessary. [0003] Traditional temperature and humidity acquisition systems use traditional wired data transmission, which will be subject to electromagnetic interference from other lines during data transmission, which will attenuate the signal and affect the real data. Contents of the invention [0004] Aiming at the above existing problems, the present...
