水温骤变是影响鱼苗成活率最主要原因之一,如何保证水温的恒定是家鱼养殖难题之一。一般来说要实现对水温的测量与控制,传统方式需要在控制室与鱼塘水温测量地点之间铺设许多的电缆。本文采用无线温度控制的方案,不必铺设电缆,还可以节省大量成本。因此专为水温控制系统的远程监控设计的研究就显得尤为重要。本设计是以STC89C52单片机为核心的无线温度控制系统。温度信号由数字温度传感器DS18B20采集,并以数字信号传输给单片机,以数字温度传感器作感温元件的数字式温度计,解决传统的温度检测可靠性差,测量温度准确率低的缺点,它以单总线的连接方式,使电路大大的简化。
Sudden changes in water temperature affect the survival rate of fry one of the most important reasons, how to ensure the constant water temperature is one of the problems of domestic fish farming. In general, to achieve the measurement and control of water temperature, the traditional way requires laying a lot of cables between the control room and the location of the fish pond water temperature measurement. This article uses a wireless temperature control program, without laying cables, you can also save a lot of cost. Therefore, the design of remote monitoring and control system for water temperature control is particularly important. The design is based on STC89C52 microcontroller as the core of the wireless temperature control system. The temperature signal is collected by the digital temperature sensor DS18B20 and transmitted to the microcontroller by the digital signal. The digital thermometer with digital temperature sensor as the temperature sensing element solves the defect that the traditional temperature detection has poor reliability and the temperature accuracy is low, The connection, so that the circuit greatly simplified.
