In order to avoid external interference factors and improve the accuracy of temperature sampling, a temperature monitoring processing unit is designed to process the output signal of the infrared temperature sensor J1.
红外温度传感器J1的输出信号首先送入红外温度采样电路中进行放大,其中,电容C1对红外温度传感器J1的输出信号进行低通滤波后,由三极管Q1对温度检测信号进行快速放大,提高温度采样效率。为了保证测量的稳定性,采用信号放大补偿电路对红外温度采样电路的输出信号进一步处理,其中,二极管 D1对三极管Q1的输出信号进行限幅后,送入运放器AR1中进行运放处理,在运放过程中,电阻R8与电容C5在运放器AR1的负反馈端起到阻容补偿的作用,提升温度采样的连续性,降低监测系统误差。稳定幅值电路中电阻R9、三极管 Q2与稳压二极管DZ1形成三极管稳压器,利用三极管稳压原理对运放器AR1的输出信号进行稳压处理,提升温度采样数值的稳定性。然后运放器AR2利用电压跟随器原理将三极管稳压器的输出信号进行隔离输出后送入控制器中,保证控制器信号接收与内部运算处理的稳定性,从而有效提高水溶反应温度监测的实时性和准确度。The output signal of the infrared temperature sensor J1 is first sent to the infrared temperature sampling circuit for amplification. After the capacitor C1 performs low-pass filtering on the output signal of the infrared temperature sensor J1, the temperature detection signal is rapidly amplified by the transistor Q1 to improve the temperature sampling. efficiency. In order to ensure the stability of the measurement, the signal amplification compensation circuit is used to further process the output signal of the infrared temperature sampling circuit. The diode D1 limits the output signal of the transistor Q1, and then sends it to the operational amplifier AR1 for operational amplifier processing. During the op amp process, the resistor R8 and the capacitor C5 play the role of resistance-capacitance compensation at the negative feedback end of the op amp AR1, which improves the continuity of temperature sampling and reduces the monitoring system error. In the stable amplitude circuit, the resistor R9, the transistor Q2 and the Zener diode DZ1 form a transistor voltage stabilizer, and the output signal of the op amp AR1 is stabilized by using the transistor voltage stabilizer principle to improve the stability of the temperature sampling value.
