Multifunctional temperature and humidity monitoring system based on RFID (radio frequency identification) technology

Abstract

The invention provides a multifunctional temperature and humidity monitoring system and a method thereof based on a 433MHz active RFID (radio frequency identification) technology, and the system is mainly applied to the field of temperature and humidity monitoring. The system consists of one or more than one central controller and multiple temperature and humidity acquisition labels which are in wireless connection, wherein the central controller comprises a wireless transceiving module and an MCU (micro control unit) central control module; each temperature and humidity acquisition label comprises a wireless transceiving module and a temperature and humidity sensor; the system is provided with a GPRS (general packet radio service) module used for sending short messages for alarm; and in addition, the system also comprises a GPS positioning module capable of monitoring the position and operation track of a carrier vehicle in real time, sending the short messages and uploading temperature and humidity information to an upper layer control system through the GPRS module. The patent of the invention also comprises a temperature and humidity monitoring method used for collecting and displaying the temperature and humidity information, processing alarm information, sending the alarm information to telephones of related persons through the GPRS module and simultaneously processing the data uploaded by a GPS system.

Description

technical field [0001] The patent of the invention is applied in the field of temperature and humidity monitoring, which can collect temperature and humidity information accurately in real time, and send and receive information through wireless radio frequency. technical background [0002] At present, with the continuous advancement of science and technology, the requirements for temperature and humidity of biological products in hospitals and laboratories of scientific research units are getting higher and higher. However, most units still use the original manual recording method. This method has many disadvantages: such as a large amount of data collection, time-consuming and waste of manpower; the temperature and humidity information cannot be dynamically displayed, and it is difficult to store the recorded information; frequent personnel Entering and exiting the warehouse will affect the indoor temperature and humidity, causing immeasurable losses to biological products...

Problems solved by technology

However, most units still use the original manual recording method. This method has many disadvantages: such as a large amount of data collection, time-consuming and waste of manpower; the temperature and humidity information cannot be dynamically displayed, and it is difficult to store the recorded information; frequent personnel Entering and leaving the warehouse will affect the indoor temperature and humidity, causing immeasurable losses to biological products; in addition, there are disadvantages such as untimely and inaccurate alarms in manual records

It can be seen that the traditional temperature and humidity collection methods have become less and less suitable for the needs of the current situation.
