4results about How to "Fast decoding" patented technology

This application discloses an encoding method, a decoding method, an electronic device, and a readable storage medium, relating to the field of programmable logic controller (PLC) technology. The method includes: identifying instruction characteristics of an instruction; determining the instruction code type based on the instruction characteristics, wherein the instruction code type includes basic fixed-length instruction code, fixed extended instruction code, extended long instruction code, and variable-length instruction code; and filling the instruction code field of the instruction according to the instruction code type to obtain the target instruction code. This application solves the problem of low encoding efficiency in PLC instruction encoding methods and effectively improves decoding speed.

This invention provides an automatic billet information tracking and receiving / sending control method based on a steel rolling heating furnace, relating to the field of steel production technology. The method includes the following steps: Step 1: Receiving billet coding information from the steelmaking system via a gateway communication device between steelmaking and rolling; Step 2: Determining if the coding information is correct. If it does not conform to the rules, the system returns to receive the coding information again and returns an error instruction to the steelmaking system; Step 3: Upon receiving data that conforms to the rules, the system calls the information decoding module to perform protocol decoding on the received data; Step 4: Generating a tracking sequence from the decoded data according to the data definition. This invention quickly, accurately, and in real-time decodes the billet coding data sent from the steelmaking system, achieving fully automatic billet tracking from the hot conveyor roller to the furnace. It then matches the weighing, length measurement, and temperature data with the steelmaking flow data, re-matches and returns the data to the steelmaking system, facilitating collaborative work between the steel rolling and steelmaking systems.

This invention provides a data storage device and a decoding method selection method. The data storage device includes a controller and non-volatile memory. The non-volatile memory stores multiple instructions, and the controller executes these instructions to implement the decoding method selection method, which includes: determining if a first read voltage from a previously correctly read data is stored; determining if hard decoding based on the first read voltage has failed; obtaining the symptom weight of the hard decoding; finding the number of reads required for soft decoding based on the first read voltage according to the symptom weight; and determining if soft decoding based on the first read voltage has succeeded. This allows for fast soft decoding, saving the time required to track the read voltage.
