Abstract
Description
Technical Field
[0001] This invention relates to the field of elevator accuracy detection technology, specifically a method for detecting the accuracy of an elevator intelligent identification device. Background Technology
[0002] Elevator encoders are typically mounted on the main shaft or door operator electrode shaft. Disassembly and assembly are cumbersome and require meticulous attention to detail, making repair and replacement difficult. Encoders are frequently affected by packaging, manufacturing, transportation damage, improper installation, inadequate maintenance, and external interference with signal transmission. Loose encoder signal lines, worn code discs, and misalignment between the encoder bushing and the motor shaft can all cause signal loss. If other components or control systems malfunction, the elevator will lose protection, potentially leading to unexpected movement, overshooting, or bottoming out. Furthermore, encoder failure can cause sudden stops during operation. The abnormally high acceleration caused by these malfunctions can pose a risk of injury to passengers.
[0003] Explosions and fires caused by electric vehicles and gas cylinders entering elevator cars are frequent, causing incalculable losses to people's lives and property. In response, many technology companies have developed corresponding AI alarm devices, such as the elevator status detection device and elevator abnormal status alarm method disclosed in publication number CN116835403A. The elevator status detection device includes a flow velocity sensor, a data acquisition module, a wireless communication module, and an external data processing terminal. The flow velocity sensor includes a container, a fixing device, a velocity-measuring fluid, a flexible substrate layer, a flexible surface layer, a friction layer, and an electrode layer. The external data processing terminal consists of a data receiving module, a data analysis module, a data recording module, and an alarm module. The elevator abnormal status alarm method determines the elevator's operating status based on the output voltage of the elevator status detection device, detects elevator stall events, and, upon detecting a stall event, sends a signal to the outside world and the elevator control module via Bluetooth communication, enabling timely alarm functionality to prevent missed rescue opportunities due to personnel's inability to independently trigger an alarm.
[0004] However, the technical capabilities of various products vary, and due to the lack of a complete testing system and unified testing standards, the accuracy of elevator intelligent identification devices cannot be tested. Therefore, we propose a method for testing the accuracy of elevator intelligent identification devices. Summary of the Invention
