Abstract
At present, traditional Chinese medicine is still stored in the traditional way, with defects such as poor management of medicinal materials and slow taking of medicines. In order to improve the storage environment of traditional Chinese medicine and ensure the efficacy of traditional Chinese medicine, the research and development of intelligent Chinese medicine cabinet is imperative.Based on single chip microcomputer and sensor technology, this paper designs an intelligent Chinese medicine environmental parameter monitoring and control system. STC89C52 single chip microcomputer as the main control chip; DHT11 temperature and humidity sensor is used to monitor the temperature and humidity of medicine cabinet in real time. The threshold setting, mode switching and interface switching of medicine cabinet are carried out by pressing buttons. LCD1602 display screen is used to display the real-time temperature and humidity of the medicine cabinet and the setting threshold. Four relays are used to adjust the temperature and humidity parameters of the medicine cabinet, so that the medicine cabinet is in the best state suitable for the storage of traditional Chinese medicine. The sound and light alarm is used to remind the medicine cabinet manager; Through the cooperation of the above modules, the preset functions of the system are completed. The intelligent medicine cabinet management system monitors the storage of traditional Chinese medicine in the medicine cabinet in real time and plays a key role in ensuring the efficacy of traditional Chinese medicine. The research and development of this system has solved the problems of storage safety of medicine cabinet, medicine management and so on, and greatly improved the work efficiency of Chinese medicine administrators.
Key words：STC89C52 MCU; Chinese medicine cabinet; Temperature and humidity; LCD1602, measurement and control
