German CABINET HOME sensor CABINET HOME model CABINET HOME price

CABINET HOME sensor is a device that converts optical signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a material absorb the energy of photons when light strikes certain substances, resulting in corresponding electrical effects. Based on the different phenomena of the photoelectric effect, it is classified into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells. The performance and characteristic curves of photoelectric devices are analyzed.

CABINET HOME sensor classification

Lasers can be classified into 4 types based on the working medium. (1) Solid-state lasers: The working medium is solid. Common types include ruby lasers, neodymium-doped yttrium aluminum garnet lasers (i.e., YAG lasers), and neodymium glass lasers. Their structures are roughly similar, characterized by compactness, robustness, and high power. Neodymium glass lasers are the devices with the highest pulsed output power, reaching tens of megawatts. (2) Gas lasers: The working medium is gas. Various gas atomic, ion, metal vapor, and gas molecular lasers are now available. Common types include carbon dioxide lasers, helium-neon lasers, and carbon monoxide lasers. They are shaped like ordinary discharge tubes, characterized by stable output, good monochromaticity, and long life, but have lower power and lower conversion efficiency. (3) Liquid lasers: These can be further divided into chelate lasers, inorganic liquid lasers, and organic dye lasers, among which organic dye lasers are the most important. Their main feature is continuously tunable wavelength. (4) Semiconductor lasers: This is a relatively newer type of laser, with gallium arsenide lasers being the more mature variant. They are characterized by high efficiency, small size, light weight, and simple structure, making them suitable for use on aircraft, warships, tanks, and as portable equipment for infantry. They can be made into rangefinders and sights. However, they have lower output power, poorer directionality, and are significantly affected by ambient temperature.

CABINET HOME sensor principle

When a laser sensor operates, a laser emission diode first emits laser pulses toward the target. After reflection from the target, the laser scatters in various directions. Part of the scattered light returns to the sensor receiver, where it is received by the optical system and imaged onto an avalanche photodiode. An avalanche photodiode is an optical sensor with internal amplification capability, allowing it to detect extremely weak optical signals and convert them into corresponding electrical signals. A common type is the laser distance sensor, which determines the target distance by recording and processing the time elapsed from the emission of the light pulse to its reception. Laser sensors must measure the transmission time with extreme precision because the speed of light is very fast.

CABINET HOME sensor applications

Over-dimensional detection of vehicle width and height: Laser sensors are used for rapid measurement. The network kernel of the PC industrial PC and visualization programming software VB is utilized for real-time data transmission and processing with the sensors. Additionally, user-friendly upper-computer control software has been designed. Field test data indicates that the system offers good real-time performance and high measurement accuracy, demonstrating practical value. Highway toll stations: Used at highway toll stations for vehicle counting and safety protection. Malaysia's Teras company has already applied hundreds of sets of BEA laser sensors in its manual and automatic toll station systems. The laser sensors adopt the Time-of-Flight (TOF) measurement principle, forming 4 planes within the detection area to monitor vehicles. The product also features anti-rear-end collision and vehicle safety protection functions. Compared to traditional light curtains, laser sensors offer advantages such as high sensitivity, high accuracy, easy installation, cost-effectiveness, and strong stability. Google's second-generation driverless car: Equipped with laser sensors, the prototype of Google's second-generation autonomous vehicle retains a prominent top-mounted laser sensor, while other sensors are discreetly integrated. Distinctive Google driverless car logos are affixed to the front, rear, and sides of the vehicle. The control and driving principle of the Google driverless car involves numerous sensors installed around the vehicle that continuously collect precise data about the vehicle itself and its surroundings. This data is analyzed and computed by the onboard processor, which then controls the vehicle's movement based on the results. The driverless car utilizes GPS equipment and sensors to accurately determine the vehicle's position and forward speed, identifying pedestrians, vehicles, bicycles, traffic lights, and many other objects in the vicinity. The roof of this Lexus vehicle features a 360° rotating laser holographic sensor, capable of simultaneously sensing conditions in front of, to the sides of, and behind the vehicle. Data collected by the sensor is transmitted via green data cables to the processor located on the right rear side of the vehicle. This laser sensor also enables global precise positioning for the driverless car. The original L style Lexus emblem on the front of the car has been removed and replaced with a radar sensor, used to measure forward distance and vehicle speed to assess traffic conditions ahead and control safe acceleration and deceleration. Position sensors are also installed on the tire hubs to detect wheel rotation, aiding in vehicle localization. The heart of the Google driverless car—the processor—is located on the right rear side of the vehicle. Data information from all sensors is transmitted here via data cables for software analysis and processing, enabling precise sensing and judgment of different objects near the driverless car. In addition to analyzing and judging the current positions of objects around the driverless car, the vehicle uses software calculations to accurately predict the potential next position of each object. Finally, the driverless car makes safe driving decisions based on all collected data, including controlling vehicle speed and maintaining distance from surrounding vehicles.
