摘要：本文介绍了采用温度传感器DS18B20采集温度、STC89C52单片机处理、LCD1602液晶显示、及NRF24L01无线收发一体模块组成的新型温度无线采集预警系统,该系统以STC89C52单片机为控制核心,利用温度传感器 DS18B20测量温度值,NRF24L01实现温度的传输。本系统分三个测温段,分别为:恒温运输18℃~22℃、冷藏运输0℃~7℃、冷冻运输?18℃~?22℃。在三个分段车厢内,一旦温度超过其上限值或下限值,接收端单片机便启动报警系统。该系统精度高、测温准确、报警及时,可广泛应用于冷藏车运输。
This paper introduces a new kind of wireless temperature acquisition using temperature sensor DS18B20 temperature acquisition, STC89C52 MCU processing, LCD1602 liquid crystal display, and nRF24L01 wireless transceiver integrated module is composed of a novel temperature collection and wireless early warning system is introduced in this paper, the system uses STC89C52 MCU as control core, using temperature sensor DS18B20 temperature measurement value, nRF24L01 achieve the temperature transmission. The system is divided into three measuring section, re-spectively: transportation with constant temperature of 18 degrees - 22 degrees C, refrigerated transport 0 DEG C - 7 DEG C, refrigerated transport ?18 DEG C - ?22 degrees. Repeated segments inside, once the temperature exceeds the upper or lower limit, the receiver chip will activate alarm system. The system has high precision, accurate temperature measurement and alarm, which can be widely used in the transport of refrigerated trucks.
