针对大中型超市冷柜中的食品温度需要进行实时监测，进而保证食品质量的问题，提出基于 Lab VIEW 的超市冷柜温度监测系统。采用 ZigBee 无线通信技术，通过星形网络实现主从节点之间数据采集与传输。子节点温度传感器将所采集到的信息传送给协调器，协调器负责接收子节点传来的温度信息。在监控机房，协调器与 PC 机利用串口连接，通过监测界面实时监测各冷柜的温度，同时完成对采集数据的保存。既实现了采集监测和超值报警的功能，又可以实现本机历史查询和远程登录数据库查询，节省人力和资源的同时，方便上级对各连锁超市的考核工作。

We propose a Lab VIEW-based supermarket freezer temperature monitoring system in light of the problem that the food temperatures in freezers at the large and medium-sized supermarkets need to be monitored and thus to ensure the qualities of the foods.ZigBee wireless communication technology is used,and the data collection and transmission between the master and slave nodes are realised through the star networks.The temperature sensor of the child node transmits the collected information to coordinator,and the coordinator is responsible for receiving the temperature information from the child node.In monitor room,the coordinator and the PC monitor the temperatures of each freezer timely using the serial port connection and through the monitoring interface,and complete the preservation of the collected data at the same time.This system realises the functions of collection and monitoring as well as over-temperature alarming,besides,it also realises the local machine history query and the telnet logon database query.While saving the manpower and resources,the system is also convenient for the higher-ups to examine the works of every chained supermarket.
