The invention relates to an olfactory sensing device capable of judging smell sources and a mobile robot, and the device comprises two olfactory sensors which are distributed at different positions, each sensor is provided with a plurality of detection points, and different detection points generate different responses to the same smell; an actuator that drives the sensor to displace; the encoder is used for pulse encoding of the output of each olfactory sensor, and the encoding rule is that when the signal change degree exceeds a first threshold value, an output peak is triggered to serve as an event; the SNN neural model is used for receiving the time sequence formed by encoding as model input and generating an output pulse sequence representing odor classification and concentration; the processor is used for controlling the actuator to drive the two sensors to perform at least one variable angle displacement in the connecting line direction, and acquiring an output pulse sequence generated by the gas detection executed by the two sensors before and after the variable angle displacement from the SNN neural model; and the smell source direction is judged according to the concentration data of the target gas output by the two sensors before and after the variable-angle displacement.

    本发明涉及一种能够判断气味来源的嗅觉传感装置、移动机器人,包括:分布于不同位置的两个嗅觉传感器,每个传感器有多个检测点,不同检测点对同一气味产生不同响应;致动器,驱动传感器进行位移;编码器,脉冲编码每个嗅觉传感器的输出,编码规则为在信号变化程度超过第一阈值时触发输出尖峰作为事件;SNN神经模型,接收编码形成的时间序列作为模型输入,产生表征气味分类和浓度的输出脉冲序列;处理器,控制致动器驱动两个传感器的连线方向进行至少一次变角度位移,从SNN神经模型获取变角度位移前后两个传感器执行气体检测所产生的输出脉冲序列,依据变角度位移前后两个传感器所输出的目标气体的浓度数据判断气味来源方向。
