How does the elevator automatic rescue operating device start and function when the elevator loses power or fails?
Publish Time: 2024-12-30
The elevator automatic rescue operating device is a functional device that automatically starts and safely returns the elevator to the designated floor when the elevator loses power or fails.1. Power supply monitoringMains power monitoring: The device has a built-in power monitoring module to monitor the elevator power supply status in real time. When the mains power supply is interrupted or the voltage is abnormal, the monitoring module will immediately detect and trigger the emergency procedure.Backup power supply: The device is equipped with a backup power supply (such as a battery), which automatically switches to the backup power supply when the mains power is interrupted to ensure the continuation of the rescue operation.2. Fault detectionControl system monitoring: The device is connected to the elevator control system to monitor the operating status of the elevator in real time. When the elevator control system fails and the elevator cannot operate normally, the device will automatically detect the fault and start the rescue mode.Safety circuit monitoring: Monitor the elevator's safety circuit, including the status of safety devices such as door locks and safety clamps. If the safety circuit is disconnected or there are other safety faults, the device will respond immediately.3. Automatic startEmergency start: When the mains power is interrupted or the elevator control system fails, the device will automatically start the rescue operation program without manual intervention.Priority setting: The device has a higher priority and can automatically take over the elevator control in an emergency to ensure that the rescue operation is prioritized.4. Rescue operation controlTarget floor selection: The device pre-sets the target floor for rescue, usually the bottom floor or the nearest floor, so that passengers can evacuate safely.Leveling control: Through the precise leveling control algorithm, ensure that the elevator stops accurately at the target floor and the error is controlled within a safe range.Slow speed operation: During the rescue operation, the elevator runs at a lower speed to ensure the safety and comfort of passengers.5. Safety measuresMultiple protections: The device has built-in multiple safety protection mechanisms, such as overcurrent protection, short circuit protection, overheating protection, etc., to ensure safety during the rescue operation.Emergency stop: During the rescue operation, if a new fault or safety hazard is detected, the device will stop running immediately and issue an alarm signal.6. Communication and promptsVoice prompts: The device is equipped with a voice prompt system. During the rescue operation, the current status and precautions are broadcast to passengers through the speakers in the elevator to calm the passengers.External communication: The device is connected to the elevator monitoring system to upload the rescue operation status and fault information in real time, which is convenient for remote monitoring and management.7. Operation records and analysisData recording: The device records the data of the entire rescue operation, including start-up time, operation parameters, fault information, etc., which is convenient for subsequent analysis and improvement.Fault diagnosis: By analyzing the recorded data, the cause of the fault can be quickly located and the maintenance efficiency can be improved.8. Recovery and shutdownNormal operation recovery: When the city power is restored or the fault is eliminated, the device automatically stops the rescue operation and the elevator resumes normal operation mode.Manual shutdown: When necessary, the staff can manually shut down the rescue operation device through the control panel for manual operation.The elevator automatic rescue operating device automatically identifies power outages or faults by monitoring the power supply and operation status of the elevator in real time, and safely returns the elevator to the designated floor through the backup power supply and rescue operation control to ensure the safe evacuation of passengers. This device combines multiple functions such as power monitoring, fault detection, automatic control, safety protection and communication prompts, providing strong guarantee for the safe operation of elevators in emergency situations.
