技术领域technical field
本实用新型涉及光幕传感器技术领域，尤其涉及一种双层光幕传感器性能测试装置。The utility model relates to the technical field of light curtain sensors, in particular to a performance testing device for double-layer light curtain sensors.
背景技术Background technique
目前，光幕传感器由一对发光器、接收器组成，发光器向接收器发射若干束红外线形成光幕，当光幕被遮挡时，光幕传感器发出遮光信号。作为安全防护装置，光幕传感器在机械加工、汽车制造、电器生产、电梯、医疗设备等领域有着广泛应用。At present, the light curtain sensor is composed of a pair of light emitters and receivers. The light emitter emits several beams of infrared rays to the receiver to form a light curtain. When the light curtain is blocked, the light curtain sensor sends out a shading signal. As a safety protection device, light curtain sensors are widely used in machining, automobile manufacturing, electrical appliance production, elevators, medical equipment and other fields.
双层光幕传感器由两组单层光幕传感器组成，用于高安全等级防护和物体位置跟踪测量，如在大型医学影像设备SPECT(Single Photon Emission Computed Tomography，单光子发射断层成像)中，要求两个重达数百公斤的探测器尽量贴近人体表面，但不能接触；在全身扫描成像过程中，探测器还需具有人体轮廓自动跟踪功能。为实现探测器对人体表面轮廓的感知，通常在探测器表面安装双层光幕传感器，用以测量探测器表面与人体轮廓之间的距离，由于涉及人身安全，对双层光幕传感器的工作性能和可靠性具有较高要求，双层光幕的遮光性、响应时间、抗干扰性能，以及可靠性等性能需严格测试，但现有技术中并没有专用于双层光幕传感器的自动化测试装置。The double-layer light curtain sensor consists of two sets of single-layer light curtain sensors, which are used for high-level protection and object position tracking measurement. The two detectors weighing hundreds of kilograms are as close to the surface of the human body as possible, but they cannot touch them; during the whole-body scanning imaging process, the detectors also need to have the function of automatically tracking the contours of the human body. In order to realize the detector's perception of the contour of the human body surface, a double-layer light curtain sensor is usually installed on the surface of the detector to measure the distance between the detector surface and the contour of the human body. Because it involves personal safety, the work of the double-layer light curtain sensor Performance and reliability have high requirements. The shading performance, response time, anti-interference performance, and reliability of the double-layer light curtain need to be strictly tested. However, there is no automated test dedicated to the double-layer light curtain sensor in the prior art. device.
