　　在济南的大街小巷，伸缩棚作为遮风挡雨的实用设施随处可见，但你是否知道，如今的伸缩棚早已暗藏 "黑科技"？尤其是自动防夹功能，就像一位隐形的卫士，在伸缩棚运行时默默守护着人们的。这种看似简单的功能，背后却蕴含着精巧的设计与技术，让我们一起揭开它的神秘面纱。

　　In the streets and alleys of Jinan, retractable sheds can be seen everywhere as practical facilities for shelter from wind and rain, but did you know that today's retractable sheds have already hidden "black technology"? Especially the automatic anti pinch function, like an invisible security guard, silently guarding people's safety during the operation of the retractable shed. This seemingly simple function, behind it lies exquisite design and technology, let's uncover its mysterious veil together.

　　敏锐的 "触觉神经"：防夹传感器的神奇作用

　　The sharp 'tactile nerve': the magical effect of anti pinch sensors

　　自动防夹功能的核心在于各类传感器的应用，它们如同伸缩棚的 "触觉神经"，能够敏锐感知外界的障碍物。在济南的伸缩棚中，常见的传感器有红外传感器和压力传感器。红外传感器通常安装在伸缩棚的边缘或轨道两侧，形成一道看不见的红外光束。当有人或物体进入光束范围内，传感器会立即检测到光束被阻断，迅速向控制系统发出信号，使伸缩棚停止运行或改变运动方向，避免夹伤事故发生。这种传感器反应迅速，能够在毫秒级时间内做出判断，适用于人流量较大的公共场所。

　　The core of the automatic anti pinch function lies in the application of various sensors, which are like the "tactile nerves" of a retractable shed, capable of keenly sensing external obstacles. In the telescopic shed in Jinan, common sensors include infrared sensors and pressure sensors. Infrared sensors are usually installed at the edge of the retractable shed or on both sides of the track, forming an invisible infrared beam. When someone or an object enters the range of the beam, the sensor will immediately detect that the beam is blocked and quickly send a signal to the control system, causing the retractable shed to stop running or change the direction of movement to avoid injury accidents. This type of sensor responds quickly and can make judgments within milliseconds, making it suitable for public places with high pedestrian traffic.

　　压力传感器则更多用于伸缩棚的接触式防夹。它通常被嵌入在棚体的边缘或折迭部位，当棚体在伸缩过程中接触到障碍物时，压力传感器会感受到异常的压力变化，并将这一信号传递给控制系统。控制系统接收到信号后，会立即命令电机停止转动，防止夹伤。在济南的一些商业场所，这种压力传感器常常与柔软的橡胶条配合使用，既能提高检测的灵敏度，又能在接触时起到一定的缓冲作用，进一步增强性。

　　Pressure sensors are more commonly used for contact type anti pinch in retractable sheds. It is usually embedded at the edge or folding part of the shed. When the shed touches an obstacle during the expansion and contraction process, the pressure sensor will sense abnormal pressure changes and transmit this signal to the control system. After receiving the signal, the control system will immediately command the motor to stop rotating to prevent injury. In some commercial places in Jinan, this pressure sensor is often used in conjunction with soft rubber strips, which can improve the sensitivity of detection and provide a certain buffering effect when in contact, further enhancing safety.

　　智能的 "大脑"：控制系统的精准指挥

　　Intelligent 'brain center': precise command of control system

　　如果说传感器是伸缩棚的 "触觉神经"，那么控制系统就是它的 "大脑"，负责对传感器传来的信号进行处理和判断，并发出相应的指令。济南伸缩棚的控制系统通常采用微处理器或 PLC（可编程逻辑控制器），具有强大的数据处理和逻辑判断能力。

　　If the sensor is the "tactile nerve" of the retractable shed, then the control system is its "brain center", responsible for processing and judging the signals transmitted by the sensor, and issuing corresponding instructions. The control system of Jinan telescopic shed usually uses microprocessors or PLCs (programmable logic controllers), which have powerful data processing and logical judgment capabilities.

　　当传感器检测到障碍物后，控制系统会对信号进行分析，判断是真实的障碍物还是误触发。如果是误触发，比如树叶飘过红外光束，控制系统会忽略该信号，避免伸缩棚频繁停止影响正常使用；如果确认是真实的障碍物，控制系统会立即发出停止或反转的指令，使棚体迅速停止运动或向相反方向移动。一些的控制系统还具备记忆功能，能够记录之前的防夹事件，为后续的维护和优化提供数据支持。

　　When the sensor detects an obstacle, the control system will first analyze the signal to determine whether it is a real obstacle or a false trigger. If it is a false trigger, such as a leaf floating over an infrared beam, the control system will ignore the signal to avoid frequent stopping of the retractable shed and affecting normal use; If it is confirmed to be a real obstacle, the control system will immediately issue a stop or reverse command, causing the shed to quickly stop moving or move in the opposite direction. Some advanced control systems also have memory functions, which can record previous anti pinch events and provide data support for subsequent maintenance and optimization.

　　可靠的 "动力保障"：电机与传动系统的设计

　　Reliable 'power guarantee': safe design of motors and transmission systems

　　电机和传动系统是伸缩棚实现自动防夹功能的 "动力保障"，它们的设计同样关重要。济南伸缩棚通常采用具有过载保护功能的电机，当电机负载超过额定值时，过载保护装置会自动切断电源，防止电机因过载而损坏，同时也避免了因电机持续运转导致的夹伤风险。

　　The motor and transmission system are the "power guarantee" for the automatic anti pinch function of the telescopic shed, and their safety design is equally crucial. Jinan retractable sheds usually use motors with overload protection function. When the motor load exceeds the rated value, the overload protection device will automatically cut off the power supply to prevent the motor from being damaged due to overload, and also avoid the risk of injury caused by continuous operation of the motor.

　　在传动系统方面，一些伸缩棚采用了摩擦离合器或联轴器等装置。这些装置在遇到过大阻力时会自动打滑或断开，使传动系统与电机分离，从而阻止棚体继续运动。这种机械设计与电子防夹功能相辅相成，进一步提高了伸缩棚的性。

　　In terms of transmission system, some telescopic sheds use devices such as friction clutches or safety couplings. These devices will automatically slip or disconnect when encountering excessive resistance, separating the transmission system from the motor and preventing the shed from continuing to move. This mechanical safety design complements the electronic anti pinch function, further improving the safety of the retractable shed.
