济南地库冬季防风卷帘门故障排查：不落或自动升起？这样解决更稳妥

　　Troubleshooting of winter windproof rolling shutter door in Jinan basement: does it not fall or automatically rises? This is a more secure solution

　　济南冬季地库的防风卷帘门、快速自动门不仅承担着防风保温的核心职责，部分还需契合停车场消防合规要求——比如坡道出入口的防火分隔，若门体出现不落、落一半自动升起的故障，既影响通行效率，还可能破坏消防防护体系。今天就为济南地库管理者和使用者科普实用故障排查方法，兼顾冬季使用需求与消防合规性，快速恢复门体正常运行。

　　The windproof rolling shutter doors and fast automatic doors in winter underground warehouses in Jinan not only bear the core responsibility of windproof insulation, but also need to comply with the fire safety compliance requirements of parking lots, such as the fire separation at ramp entrances and exits. If the door body fails to fall or automatically rises halfway down, it will not only affect traffic efficiency but may also damage the fire protection system. Today, we will popularize practical troubleshooting methods for Jinan underground warehouse managers and users, taking into account winter usage needs and fire compliance, and quickly restoring the normal operation of the door body.

　　遇到门体升降异常，从易排查的操作层面入手。先检查急停按钮是否被误按，冬季地库人员通行频繁，可能因碰撞、误触导致急停触发，门体将暂停所有自动操作，恢复急停按钮后可再次尝试启动；同时观察控制面板的显示代码，若数字频繁跳动却不执行指令，大概率不是操作失误，需进一步排查硬件或参数问题。

　　When encountering abnormal door lifting, start with the easiest operational level to troubleshoot. First, check if the emergency stop button has been pressed incorrectly. In winter, the underground warehouse personnel frequently pass through, and the emergency stop may be triggered due to collisions or accidental touches. The door will pause all automatic operations, and once the emergency stop button is restored, it can be attempted to start again; At the same time, observe the display code on the control panel. If the numbers frequently jump but instructions are not executed, it is likely not an operational error and further investigation of hardware or parameter issues is needed.

　　红外对射系统异常是冬季高发故障，济南冬季低温易导致镜片结霜、积尘，或碰撞后镜片偏移，都会影响对射精准度。红外对射的核心作用是检测通行障碍，若镜片未竖直对齐、表面有冰霜灰尘，门体为避免碰撞会拒绝下落，或下落中触发保护机制自动升起。排查时可先擦拭镜片，冰霜与灰尘，再轻轻调整镜片竖直状态，确保对射通畅；若拔掉红外电源插头后门体能正常下落，说明红外对射存在校准问题，重新对齐后插好插头即可恢复。

　　Abnormal infrared imaging system is a common malfunction in winter. The low temperature in Jinan during winter can easily cause lens frosting, dust accumulation, or lens displacement after collision, which can affect ejaculation accuracy. The core function of infrared radiation is to detect passage obstacles. If the lens is not vertically aligned or there is frost and dust on the surface, the door will refuse to fall to avoid collision, or the protection mechanism will be triggered to automatically rise during the fall. When troubleshooting, you can first wipe the lens to remove frost and dust, and then gently adjust the lens to a vertical position to ensure smooth aiming; If the door can fall normally after unplugging the infrared power plug, it indicates that there is a calibration problem with the infrared radiation. Re align and plug in the plug to restore it.

　　门体传动皮带的松紧度也会受冬季低温影响。低温可能导致皮带变硬、收缩，若门体曾被车辆碰撞，还可能出现皮带松动，运行时因受力不均引发升降异常——比如下落时皮带打滑，门体无法精准到位，触发电机保护机制自动回升。此时需调整皮带松紧度，让皮带保持适度张力，避免因传动失效导致故障，调整后可手动测试门体升降，确认皮带运行顺畅。

　　The tightness of the door drive belt is also affected by the low temperature in winter. Low temperature may cause the belt to harden and shrink. If the door has been hit by a vehicle, the belt may also become loose. During operation, uneven force may cause abnormal lifting - for example, when the belt slips during a fall, the door cannot be accurately positioned, triggering the motor protection mechanism to automatically rebound. At this point, it is necessary to adjust the tightness of the belt to maintain a moderate tension and avoid faults caused by transmission failure. After adjustment, the door body can be manually tested to ensure smooth operation of the belt.

　　上下限位参数偏移是碰撞后常见的核心故障，冬季低温也可能加剧部件变形，导致参数错位。门体的上下限位决定了升降终点，若碰撞后限位参数偏移，电机无法识别正确的落地位置，可能出现落到地面后继续下行，触发保护自动升起，或上升到中途就停止的情况。排查时可将门体切换手动模式，通过控制面板的菜单键校准：长按菜单键六秒，待显示“L1”（下限）时，按下降键让门体落到地面，松开后按确认保存；再切换“L0”（上限），按上升键调整合适高度后确认，完成参数校准，让电机精准识别升降终点。

　　The deviation of upper and lower limit parameters is a common core fault after collisions, and low temperatures in winter may also exacerbate component deformation, leading to parameter misalignment. The upper and lower limits of the door determine the lifting endpoint. If the limit parameters deviate after a collision, the motor may not be able to recognize the correct landing position, which may result in continuing to descend after landing on the ground, triggering the protection to automatically raise, or stopping halfway up. When troubleshooting, the door can be switched to manual mode and calibrated through the menu button on the control panel: long press the menu button for six seconds, wait for the display of "L1" (lower limit), press the down button to let the door fall to the ground, release it, and press confirm to save; Switch to "L0" (upper limit) again, press the up button to adjust to the appropriate height, confirm, complete parameter calibration, and allow the motor to accurately identify the lifting endpoint.

　　需要特别注意的是，若地库门涉及停车场坡道出入口的防火分隔，排查与维修时需保障消防合规性。根据消防要求，除敞开式、斜楼板式汽车库外，坡道出入口需通过防火卷帘、防火门等与停车区隔开，仅当汽车库和坡道均设置自动灭火系统时，可免设部分设施。维修时切勿破坏门体的防火密封结构，若门体为防火卷帘，调整后需确认其密封性能与升降稳定性，避免影响消防防护效果。

　　It should be noted that if the basement door involves fire separation at the entrance and exit of the parking lot ramp, fire compliance must be ensured during inspection and maintenance. According to fire safety requirements, except for open and inclined floor slab garages, ramp entrances and exits need to be separated from the parking area by fire-resistant rolling shutters, Class A fire doors, etc. Only when both the garage and ramp are equipped with automatic fire extinguishing systems, some facilities can be exempted. Do not damage the fireproof sealing structure of the door during maintenance. If the door is a fireproof rolling shutter, its sealing performance and lifting stability should be confirmed after adjustment to avoid affecting the fire protection effect.

　　针对济南冬季地库门的使用场景，建议定期做好维护：冬季每月清理红外镜片的冰霜、灰尘，检查皮带松紧度与限位参数，避免低温环境下部件故障；若门体发生碰撞，及时排查上述部位，避免小问题恶化；若门体涉及消防功能，需定期联系机构检测，确保符合防火分隔要求。出现故障时切勿强行反复启动，以免损坏电机或传动部件，可按排查步骤操作，或联系厂家售后获取技术支持，避免违规改装影响消防合规。

　　For the usage scenario of Jinan's winter underground warehouse doors, it is recommended to regularly maintain them: clean the frost and dust on the infrared lenses every month in winter, check the tightness and limit parameters of the belts, and avoid component failures in low-temperature environments; If there is a collision with the door, promptly check the above parts to avoid minor problems from worsening; If the door body involves fire protection functions, it is necessary to regularly contact professional institutions for testing to ensure compliance with fire separation requirements. When a malfunction occurs, do not forcefully restart repeatedly to avoid damaging the motor or transmission components. Follow the troubleshooting steps or contact the manufacturer's after-sales service for technical support to avoid unauthorized modifications that may affect fire safety compliance.
