Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a villa elevator structure. Background Art

[0002] Most of the current villa elevators are platform elevators without cars for the purpose of saving space. In the prior art, a car position detection device for a platform elevator disclosed in Chinese patent application number CN202320015851.8 sets a grating ruler reader on the backpack frame to detect the height position of the car in conjunction with the grating ruler. Although this design scheme meets the basic needs of elevator operation to a certain extent, it has a significant defect: it only relies on a single grating ruler reader for detection.

[0003] In practical applications, a single grating ruler reader is easily affected by a variety of external factors, such as electromagnetic interference, dust accumulation, mechanical vibration, etc. These factors may cause deviations in the data read by the reader, thereby affecting the accuracy of the car position detection. Once the detection data is inaccurate, it may cause abnormal operation of the elevator and even endanger the safety of passengers.

[0004] In addition, the design of a single reader also lacks redundancy and fault warning mechanism. Once the reader fails, the system will not be able to obtain accurate car location information in time, which may cause the elevator to stop operating or take other emergency measures, causing inconvenience to passengers and possibly increasing maintenance costs.

[0016] Beneficial effects of the present invention: The present invention realizes dual detection of the platform car frame position by setting two independent grating scale readers. When the readings of the two readers are basically consistent, the average value is taken as the final platform car frame position data, which effectively reduces the error of a single reader caused by external factors, improves the detection accuracy, ensures the smooth operation and precise parking of the elevator, and thus improves the riding experience and satisfaction of passengers; and the dual reader design provides a redundant detection mechanism. Even if one reader cannot work normally due to a fault or error, the other reader can still provide effective platform car frame position information to ensure the continuous and safe operation of the elevator system, which greatly reduces the risk of elevator shutdown caused by a single reader failure and improves the overall reliability of the system; in addition, the control system can monitor the reading difference between the two readers in real time. When the difference exceeds the preset threshold, the system will trigger a fault warning mechanism to prompt maintenance personnel to check and repair, which helps to promptly discover and deal with potential safety hazards and avoid accidents.
