Stereoscopic library Whether it can operate after power failure mainly depends on the power supply design, standby power supply configuration, equipment emergency mechanism and manual operation scheme of the system. The modern stereoscopic warehouse usually adopts various modes, such as uninterruptible power supply (UPS), standby generator, manual emergency operation, etc., to ensure that the basic operation can still be maintained in case of sudden power failure and avoid affecting production and logistics efficiency.
First of all, UPS is the standard configuration of many stereo libraries. The UPS can provide power for the control system, computer terminal, monitoring equipment, etc. in a short time after the main power supply is cut off, to ensure that data will not be lost, and to provide buffer time for the start of the standby generator. The power supply time of UPS is usually between 10 minutes and 1 hour, depending on the battery capacity and load. During this period, the control system of stereo library can execute necessary shutdown protection procedures to prevent equipment damage or data loss caused by sudden power failure.
Secondly, the standby generator is a common configuration of most large three-dimensional warehouses, especially in manufacturing, medicine, cold chain storage and other industries with high requirements for continuous operation. When the mains power supply is cut off, the standby generator can be automatically started within seconds to minutes to provide stable power for the entire stereo warehouse, so that the core equipment such as the stacker and the conveying system can continue to operate, and ensure the uninterrupted logistics. If the stereo warehouse only relies on UPS for power supply, it may only be able to maintain the operation of the control system and cannot drive large mechanical equipment, so the standby generator is crucial in the case of long-term power failure.
In addition, manual emergency operation is also an important remedial measure in case of power failure. Some key equipment, such as stacker, shuttle car and conveyor, are usually equipped with manual clutch device, manual lifting system or emergency release mechanism, allowing operators to manually control the equipment and move the goods to a safe position in case of power failure. For example, the stacker can be equipped with a manual drive mechanism to allow manual control of its horizontal or vertical movement in case of power failure, so as to complete the emergency access task in a short time and prevent the problem that the goods cannot be picked up due to power failure.
At the same time, the intelligent management system of stereo library usually has power failure protection mechanism. In case of sudden power failure, the system will automatically store the current operation status, so as to ensure that the system can continue to operate according to the original status after power supply is restored, without causing chaos in cargo access or data loss. In addition, some advanced stereo libraries also support remote monitoring and automatic alarm functions, which can send notification to management personnel in case of power failure for timely response.
In general, the operation capacity of the stereoscopic warehouse after power failure depends on the configuration of UPS, standby generator and emergency operation scheme. If only relying on UPS, it may only maintain the control system operation for a short time; If the standby generator is equipped, all functions can be recovered in a short time to maintain normal operation; The manual emergency operation is a remedial measure under bad conditions to ensure that the necessary access tasks can be completed under any circumstances. Therefore, in order to ensure the continuous operation of the stereo warehouse, it is recommended to adopt the multi-layer protection scheme of UPS+standby generator+emergency manual operation to deal with sudden power failure.
