Embodiment Construction
[0016] The present invention will be further described below in conjunction with drawings and embodiments.
[0017] The active active two-way electronic tag used in the present invention is an electronic tag with active active two-way (XTIVE RFID) technology. The electronic tag has strong anti-metal interference, anti-disassembly function, and integrated switching value and voltage input interface. And expand the sound and light output, it can be placed in the freezer or other occasions that need to detect temperature and humidity.
[0018] The RFID reader-writer matched with the active active two-way electronic tag and the active active two-way electronic tag do not need to be connected to collect data and send it to the computer of the management department at regular intervals. The timing can be passed Free configuration of hardware or software. The management software on the computer analyzes the received data, visually detects the temperature, humidity and environmental ...

The invention provides an internet-of-things technology based bidirectional cold chain management system. The system comprises a master control computer, an RFID (Radio Frequency Identification) reader, an active bidirectional electronic tag and a GSM (Global System for Mobile communications) or 3G (Three-Dimensional) receiving terminal, wherein the master control computer is connected with the RFID reader through a wireless or wired local area network and is connected with the GSM or 3G receiving terminal through a serial port or a USB (Universal Serial Bus) interface; and the active bidirectional electronic tag is communicated with the RFID reader in a radio frequency mode. The system has the advantages that: the requirements for scattered distribution, large number, high accuracy and the like are met; a bidirectional radio frequency transmission technology is adopted; wiring is not required; the installation is not limited to region or space; various detection input points can be connected and output alarm content can be defined; temperature and humidity data are detected, and data such as door opening data, detection data of other vessel equipment and the like and running data of the system can be detected; real-time alarm can be realized; and the characteristic of strategic management of the internet of things is embodied.
Description
technical field [0001] The invention relates to a wireless cold chain management system, in particular to a two-way cold chain management system based on Internet of Things technology. Background technique [0002] There are many medicines, reagents, samples and other medical and food supplies that are related to temperature and humidity in the medical, pharmaceutical and food industries. In addition to manual recording, wireless cold chain management is one-way or single-function temperature detection. [0003] The manual management method is to manually record the thermometer on the storage container to form a manual report. [0004] The wireless detection method on the market is a one-way detection network composed of multiple single-function sensors. [0005] This form is difficult to detect abnormal changes in temperature and humidity in time, and is greatly affected by the responsibility of the operator. There are many false reports, or there are reports but no on-si...
