Embodiment Construction

[0032] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the vehicle-mounted sensor rapid diagnosis system based on Telemetry technology of the present invention includes a sensor, a controller, an actuator, a T-BOX terminal, and a user terminal.

[0034] The MCU unit is deployed on the sensor, which is responsible for receiving the initialization information sent by the controller and performing sensor initialization. The initialization settings include synchronizing the sensor reference time, setting the transmission interface and sending cycle. After the sensor is started, the MCU obtains the local signal acquisition physical channel number and acquires the acquisition signal; then sends time stamp, transmission interface, sensor working status, and acquisition signal information, encapsulates them into Telemetry messages, and periodically commu...

Abstract

The invention provides a method and system for rapid diagnosis of on-board sensors based on Telemetry technology. The integrated MCU sensor is initialized according to the initialization information issued by the controller; the controller encapsulates the acquisition signal and the working status information into the Telemetry message, which is periodically reported through the transmission interface Controller; the controller receives the Telemetry message to extract the acquisition signal of the sensor, analyzes the current working status information of the sensor and judges its mode; the controller encapsulates the sensor working status diagnosis result into a Telemetry message, and sends it to the T-BOX terminal through the transmission interface for dynamic Refresh the real-time working status of the sensor. The present invention deploys the MCU in the vehicle sensor to process the Telemetry message, and monitors the working state of the sensor in real time while normally collecting and reporting the data, thereby ensuring the safety of automatic driving.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to a method and system for rapid diagnosis of vehicle-mounted sensors based on Telemetry technology. Background technique [0002] Telemetry is a remote high-speed data collection technology from physical or virtual devices. The device periodically and proactively sends the device's input and output interface statistics, time stamps, hardware status data and other information to the collector through the push mode (Push Mode), which provides A more real-time and higher-speed data acquisition function. [0003] For the sensor diagnosis technology involved in the field of automatic driving, the traditional method is mostly through UDS technology, in an offline state, through a specific diagnostic tool to connect to the vehicle ECU, and execute diagnostic commands one by one. Although this traditional sensor diagnosis method can also diagnose whether it is abnor...
