Indicator for forecasting shelf life of cold fresh pork

The invention relates to an indicator for forecasting the shelf life of cold fresh pork, belonging to the technical field of detecting the quality of the pork by acquiring the temperature of the pork. The indicator forecasts the shelf life of the pork by timely acquiring the temperature of the pork in the circulation process from output to sell. The indicator has small volume and convenient use, can be directly attached to the surface of the cold fresh pork, and timely updates and displays the temperature, the shelf life and the system time of the fresh pork. The indicator uses a high-precision temperature sensor DS18B20 to acquire the temperature of the surface of the cold fresh pork, transmits the temperature value to a micro controller MSP430F1XX through a data wire DQ, uses the controller to forecast the real-time shelf life based on the TTT theory of the temperature, and uses a liquid crystal display LM6059BCW to display real-time temperature, the shelf life, the system time and the food names. The system time, the real-time temperature and the shelf life are all memorized in an extended memory card every 1 hour, and can be transmitted to a computer through serial ports of the indicator as required by users. The indicator has high precision, low energy consumption, multiple functions and convenient operation, and effectively solves the problem for forecasting the shelf life of the cold fresh pork during circulating.
