一种三波段红外火焰探测器红外管软硬件综合温度补偿电路
摘要：
本实用新型公开了一种三波段红外火焰探测器红外管软硬件综合温度补偿电路，包括MCU、动态温度补偿电路和静态温度补偿电路；动态温度补偿电路包括放大电路，放大电路包括运算放大器U1A，运算放大器U1A的反相输入端连接有补偿电路，运算放大器的输出端连接于MCU；静态温度补偿电路包括用于采集红外管输出值的AD采样电路，AD采样电路连接有多级放大电路，并通过多级放大电路连接于MCU。本实用新型解决了现有技术中仅采用单一的温度补偿(即仅硬件温度补偿或软件算法补偿)所造成的温度补偿效果不佳的技术问题，其电路结构简单，温度补偿可靠。
摘要（英）：

The utility model discloses a temperature compensation circuit is synthesized to triband infrared flame detector infrared tube software and hardware, including MCU, dynamic temperature compensation circuit and static temperature compensation circuit, developments temperature compensation circuit includes amplifier circuit, and amplifier circuit includes operational amplifier U1A, and operational amplifier U1A's inverting input end is connected with compensating circuit, and operational amplifier's output is connected in MCU, static temperature compensation circuit is including being used for gathering the AD sampling circuit of infrared tube output valve, and AD sampling circuit is connected with the multi -stage amplifiers circuit to through multi -stage amplifiers circuit connection in MCU. The utility model provides a not good technical problem of temperature compensating effect who only adopts single temperature compensating (only hardware temperature compensating or the compensation of software algorithm promptly) to cause among the prior art, its circuit structure is simple, temperature compensating is reliable.
