This utility model relates to a front wheel steering angle sensor with adjustable range, including a sensor body, a magnetic block, and a PCB board. The sensor body is connected to the vehicle body through mounting holes, and its built-in center calibration structure is aligned with the steering axis. The magnetic block contains a radially magnetized bare magnet, which forms a magnetic field with the Hall chip on the PCB board. The PCB board is rigidly fixed to the body and is detachable, integrating a Hall sensor chip with an SPI interface for programmable operation, supporting software configuration of the detection range and zero-point parameters. The signal is converted from 3.3V to 5V via a level conversion chip, and a multi-stage power supply module provides dual-channel regulated power. After the microprocessor calculates the angle data, it is output by the CAN bus controller. This sensor establishes an initial zero point through a zero-point calibration component, featuring a compact structure and convenient installation. The software configuration is flexible and adaptable to different range requirements, making it particularly suitable for autonomous driving systems in construction machinery and agricultural machinery, effectively improving steering angle detection accuracy and multi-platform compatibility.

The invention discloses a self-adaptive question answering method based on a large language model and an intelligent large language model. The method comprises the following steps: receiving a query text input by a user; analyzing the query text by using a preset query analysis model to determine the complexity of the query text; if the complexity is a first category, the query text is directly input into a large language model to generate an answer, and the first category corresponds to a preset low-complexity query; if the complexity is a second category, the retrieval process is executed, a reference document related to the query text is obtained from a preset data source, the query text and the reference document are jointly input into the large language model to generate answers, and the second category corresponds to preset high-complexity query. According to the method, query analysis is introduced, so that shunting processing, simple direct answering and answering after complex retrieval on queries with different complexities are realized. The self-adaptive mechanism maximizes the operation efficiency of the system while ensuring the answer quality.
