Double-communication automatic switching system and method of intelligent wireless temperature and humidity monitor

Abstract

The invention discloses a dual-communication automatic switching system and method of an intelligent wireless temperature and humidity monitor. A signal detection unit in the system is used for identifying and judging a network environment and the signal strength, an LoRa serial port unvarnished transmission communication module is used for realizing the data transmission with a LoRa network, andan NB-IoT transparent transmission communication module is used for realizing the data transmission with aan NB-IoT network. A microcontroller is used for calculating and processing the data and integrating an application layer protocol, a dialogue form, a data link layer protocol and a communication format, a data acquisition unit is used for acquiring the detection data of the intelligent wireless temperature and humidity monitor, and a timer sets a signal acquisition period of the data acquisition unit. According to the method, the time synchronization is set for data acquisition and recording, the corresponding communication module is activated or closed according to a communication strategy, the data transmission is realized, and the successful transceiving is ensured. The system andthe method are suitable for the centralized and unified management and control occasions of the temperature and humidity, and realize the timely, accurate and reliable transmission of the temperatureand humidity monitoring data.

Description

technical field [0001] The invention relates to the technical field of wireless data communication, in particular to a dual-communication automatic switching system and method for an intelligent wireless temperature and humidity monitor. Background technique [0002] Temperature and humidity factors have a greater impact on electrical equipment. High temperature and high humidity will affect the operation stability of electrical equipment in terms of dielectric strength, mold growth, metal corrosion, and service life. With the development of modern industry and the improvement of the precision of electrical equipment, the requirements for the environment and monitoring of the electrical room are also increasing. At present, the management of the environmental state of the electrical room mainly adopts the method of manual periodic inspection. Due to the large scale of the factory area, the distribution of electrical rooms is scattered, it is difficult to conduct inspections,...
