摘要
随着电子、通信领域的快速发展,温度监控系统被广泛应用,温度监控在不同行业和领域又有着不同的要求和标准。本系统采用STC90C516RD+单片机给DS18B20发送指令获取温度,根据温度进行相应的控制和告警操作,并通过串口连接无线模块实现和上位机的通信。上位机软件显示、处理和保存下位机发来的温度信息,还可发送指令来控制下位机工作。实验证明,该系统电路简单、工作稳定、价格低、实用,可以满足大部分领域对温度监测的需要。
With the rapid development of electronic and communication fields,temperature monitoring system is widely used,and temperature monitoring has different requirements and standards in different industries and fields.The system uses STC90C516RD+MCU to send instructions to DS18B20 to obtain temperature,carries out corresponding control and alarm operation according to temperature value,and connects the wireless module through serial port to realize the communication with the upper computer.The upper computer software displays,processes and saves the temperature information sent by the lower computer,and also controls the operation of the lower computer by sending instructions.It is proved that the system is simple in circuit,stable in operation,low in price,and practical,and can meet the needs of temperature monitoring in most fields.
