Description

Technical field [0001] The invention relates to the technical field of vertical elevators, in particular to a real-time floor detection device and method for vertical elevators. Background technique [0002] Vertical elevators need to accurately detect real-time floors during operation. For the detection of elevator floors, acceleration sensors are usually used to detect the realization directly, that is, the acceleration sensor is arranged in the elevator, and the acceleration of the elevator is detected in real time by the acceleration sensor. Perform integration to calculate the real-time speed of the elevator, and then integrate the speed to obtain the displacement of the elevator, and then determine the real-time floor information of the elevator, but the above detection method using the acceleration sensor will have the following problems: [0003] 1. There will be cumulative errors in the acceleration detection process, that is, when the acceleration is integrated and accumu...

Problems solved by technology

[0003] 1. There will be cumulative errors in the acceleration detection process, that is, the errors will also accumulate when the acceleration is integrated and accumulated, and the detection accuracy of the acceleration will gradually decrease as time goes by. Therefore, this type uses a single acceleration detection to calculate the floor. The detection accuracy of the method will gradually decrease, and the actual detection accuracy and reliability are not high, especially when the elevator is running due to various reasons, frequent acceleration and deceleration and large vibration / jitter during operation, the measured acceleration curve will be abnormal. Complexity makes it difficult to obtain accurate detection results and further reduces the accuracy of detection;

[0004] 2. Simple acceleration detection cannot determine the real-time running status of the elevator, which makes it easy to misjudgment and cause floor calculation errors. For example, when the elevator is in the state of "stationary" and "uniform speed", the acceleration value detected by the acceleration sensor is "zero". ", that is, the acceleration value cannot distinguish whether the elevator is in a "stationary" state or a "uniform speed" running state, and once a misjudgment occurs, it will disturb the calculation of the floor;

[0005] Some practitioners proposed to use the access to the elevator equipment system to obtain the floor information of the elevator, but access to the elevator equipment system will inevitably affect the operation of the elevator, which does not comply with national regulations and has great potential safety hazards
