摘要
Measures and manages temperature and humidity according to the provisions of Hazard Analysis Critical Control Points (HACCP), which is the key point of food hazard factor management, using various information received from the sensor network that can adaptively select the communication frequency according to the communication situation A system is disclosed that can do this. According to an aspect of the present invention, there is provided a wireless communication system including a plurality of sensor nodes for measuring sensed information including at least one of a central server, temperature information, and humidity information, transmitting sensed sensed information to the central server, A gateway for performing wireless communication with at least a part of the plurality of sensor nodes and relaying the central server and the plurality of sensor nodes, and a wireless communication unit for wirelessly relaying at least a part of the plurality of sensor nodes and the gateway Wherein the central server sets a reference temperature and a temperature deviation according to HACCP rules, stores and manages temperature data received from the plurality of sensor nodes, sets a reference humidity and a humidity deviation according to the HACCP rule, And stores and manages humidity data received from the plurality of sensor nodes, And outputs a warning signal when the detection information received from the node is out of the reference value defined in the HACPP, and generates a CPP report based on the received detection information, and the gateway and the wireless router transmit the first frequency And a second frequency band that is different from the first frequency band, and when the sensor node is to perform wireless communication with the gateway, the sensor node activates the first frequency band or the second frequency band according to a wireless communication state with the gateway, 2 frequency band and performs wireless communication with the gateway in a selected frequency band and performs wireless communication with the wireless router when the wireless communication with the wireless router is performed, Or the second frequency band, and transmits the selected frequency band to the non-The HACCAP based health management system using an adaptive wireless communication that performs a wireless communication with the router is provided.;
