用于检测红外线光源的运动的传感器系统
摘要：
本发明描述一种用于检测在红外线光源(29)的预定运动方向(30)上的运动的传感器系统，其具有至少一对红外线光传感器，所述对红外线光传感器由两个红外线光传感器(4，5；36，37)组成，所述红外线光传感器相对于所述运动方向(30)并排布置，且因此界定传感器覆盖区域(17)，所述传感器覆盖区域通过所述红外线光传感器(4，5；36，37)的末端(16)之间的距离确定，所述红外线光传感器相对于所述运动方向(29)彼此背对并经配置使得在暴露于所述红外线光源(29)期间，所述传感器提供用于检测所述红外线光源(29)的运动的电荷符号是相反的电信号，使得所述信号可被分接，其中所述传感器系统(1)具有在所述红外线光传感器(4，5；36，37)与所述红外线光源(29)之间的窗(7)；且通过此窗所述红外线光源(29)的红外线光可照射于所述红外线光传感器(4，5；36，37)上；且在此窗后方布置所述红外线光传感器(4，5；36，37)；且其布置及其在所述运动方向(29)上的范围根据所述窗(7)的宽度(41)调整，使得在距所述窗(7)的预定限制距离(20)之外，所述红外线光传感器(4，5；36，37)中的每一个具有充分照明区域(22，23)，所述充分照明区域(22，23)界定位置，所述红外线光源(29)从所述位置仅充分照明所述红外线光传感器(4，36或5，37)中的其中一个，其中所述充分照明区域(22，23)在空间上不重叠超出所述限制距离(20)；且所述窗宽度(41)在所述运动方向(29)上小于所述传感器覆盖区域(17)。
摘要（英）：

A sensor system for detecting a movement of an Infrared light source (29) in a predetermined direction of movement (30) has at least one pair of infrared light sensors consisting of two infrared light sensors (4, 5; 36, 37) which are arranged beside one another with respect to the direction of movement (30) and thereby define a sensor coverage section (17), which is determined by the distance between the ends (16) of the infrared light sensors (4, 5; 36, 37) which face away from one another with respect to the direction of movement (30), and are set up in such a manner that, during irradiation with the infrared light source (29), said sensors provide electrical signals, the charge signs of which are opposing, for detecting the movement of the infrared light source (29) in a manner such that said signals can be tapped off, wherein the sensor system (1) has a window (7) between the infrared light sensors (4, 5; 36, 37) and the infrared light source (29), through which window the infrared light from the infrared light source (29) can be beamed onto the infrared light sensors (4, 5; 36, 37) and behind which window the infrared light sensors (4, 5; 36, 37) are arranged and the arrangement and extent of which are matched to the width (41) of the window (7) in the direction of movement (30) in such a manner that, beyond a predetermined limit distance (20) away from the window (7), the infrared light sensors (4, 5; 36, 37) each have a full shine area (22, 23) which defines the locations from which the infrared light source (29) fully shines on only one of the infrared light sensors (4, 36 or 5, 37), wherein the full shine areas (22, 23) do not spatially overlap beyond the limit distance (20), and the window width (41) is shorter than the sensor coverage section (17) in the direction of movement (30).
