Development of Infrared Safety Light Screen MCU
The safety light curtain consists of two parts: a light projector and a light receiver. The emitter emits modulated infrared light and is received by the receiver to form a protective net. When an object enters the protective net, when light is blocked by the object, through the internal control circuit, the receiver circuit immediately responds, that is, the output Part of it outputs a signal for emergency braking of machine tools such as punches and presses.
Components:
Light-emitting device: It is composed of several light-emitting units and emits infrared light.
Light receiver: It is composed of several light receiving units, which receive infrared light and correspond to the light emitter to form a protective light curtain, which generates light-through and light-shielding signals, which are transmitted to the controller through a signal cable.
Controller: Supply power to the illuminator and the receiver, and process the light-on and shading signals generated by the receiver, generate control signals, control the brake control circuit of the machine tool or the alarm device of other equipment, and realize the machine stop or safety alarm. The controller can be divided into built-in controller (N), external controller (W) and J-type safety interface; the built-in controller has a small and compact structure and can be installed in the electrical cabinet of machine tools or other equipment; external control The device has a beautiful and firm structure and can be directly installed on the wall of the machine tool bed or other equipment; the J-type safety interface is dedicated to systems that require level signal control to provide power and complete signal processing to ensure safe and reliable signal transmission.
Signal cable: used to transmit the signal between the controller and the light emitter and the light receiver.
Control cable: used to connect the controller and the machine tool and equipment to realize the safety control of the machine tool or other equipment.

红外安全光幕单片机开发
安全光幕由投光器和受光器两部分组成。投光器发射出调制的红外光，由受光器接收，形成了一个保护网，当是有物体进入保护网，当从中有光线被物体挡住，通过内部控制线路，受光器电路马上作出反应，即在输出部分输出一个信号用于机床如冲床，压力机等紧急刹车。
组成单元：
发光器：由若干发光单元组成，发射红外光线。
受光器：由若干受光单元组成，接受红外光线，与发光器对应，形成保护光幕，产生通光、遮光信号，通 过信号电缆传输到控制器。
控制器：为发光器、受光器供电，并处理受光器产生的通光、遮光信号，产生控制信号，控制机床的制动 控制回路或其他设备的报警装，实现机床停车或安全报警。控制器又可分为内置式控制器（N）和外置式控制器(W)和J型安全接口；内置式控制器结构小巧紧 凑，可安装在机床或其他设备的电气柜内；外置式控制器结构美观牢固，可直接安装在机床床壁上或其他设备上；J型安全接口专用于需要电平信号控制的系统提供 电源并完成信号处理，保证信号安全可靠的传输。
信号电缆：用来传输控制器和发光器、受光器之间的信号。
控制电缆：用来连接控制器和机床、设备，以实现机床或其他设备的安全控制。
