A timing controller and an operation method of the timing controller are provided. The timing controller includes a timing signal generation part and a frame signal generation part. The timing signal generation part generates a clock signal to a source driver for driving a display panel. The frame signal generation part generates a frame signal synchronized with the clock signal. The timing controller transmits a first differential signal pair and a second differential signal pair of the frame signal to the source driver via different transmission paths. The timing controller adjusts the phase of at least one of the first differential signal pair and the second differential signal pair so that the clock signal has different timing skews for different differential signal pairs, in order to adapt to different transmission path delays of the different transmission paths.

The application provides an auxiliary driving control system and a vehicle. Through double screening of a vehicle information service provider platform and a cloud computing platform, redundant data in a vehicle working condition data package is removed. The double screening mechanism avoids transmission of invalid data from the source, reduces transmission delay and cloud processing load. The instruction generation process is transferred to the cloud computing platform. The vehicle end only needs to retain the light data acquisition, encryption upload and instruction execution capability, thereby reducing the vehicle hardware cost. The vehicle-mounted system can perform auxiliary driving control based on the current network state between the vehicle-mounted information service provider platform and according to the action instruction or the redundant decision plan, thereby ensuring the availability and safety of the function under various network conditions. The vehicle-mounted system can realize smooth degradation of the function under various scenes from temporary lag to long-term disconnection, rather than directly exiting the auxiliary driving, thereby greatly enhancing the driving confidence and safety of the user in a weak network scene.

The present application belongs to the technical field of measurement of electrical variables and edge computing, and discloses an electric energy metering box monitoring system based on intelligent sensors, which comprises an intelligent sensor node and an edge control unit, and a lightweight abnormality preliminary screening model and a dual-mode communication stack are built in the node. The node reports a state vector through a message queue telemetry transport protocol under normal conditions, and the edge control unit inputs the state vector into the preliminary screening model to output a state confidence. When the state confidence is in a transition interval, the edge control unit issues an instruction, the node switches an analog-to-digital converter to a high-frequency mode, and switches a communication stack to a limited application protocol block transmission protocol based on a user datagram protocol, and transmits high-frequency sampling data to the edge control unit in blocks. The present application suppresses invalid data flow under normal conditions, avoids bus conflicts caused by sudden high-frequency data, and shortens the data acquisition and transmission delay under abnormal conditions.

This invention discloses a feed control device for a mixer, relating to the field of feed control technology. It includes: a weighing body for weighing the material reduction; a receiving bin suspended above the weighing body for receiving materials; a first screw conveyor located at the bottom of the receiving bin; a second screw conveyor located on the weighing body and below the first screw conveyor; and a differential compensation channel connecting the discharge port of the first screw conveyor and the inlet of the second screw conveyor to achieve partial material suspension, compensating for material overfeeding caused by signal transmission delay. This invention, by adding a differential compensation channel, utilizes the principle that suspended material within the channel cannot be weighed by the weighing body. When the weighing body detects that the material reduction reaches a preset value and triggers a stop signal, this suspended material precisely compensates for the extra material feeding during the delay period, completely solving the problem of excessive material feeding caused by signal delay in traditional loss-in-weight scale feed control.
