15 results about "Upgrade" patented technology

Upgrading is the process of replacing a product with a newer version of the same product. In computing and consumer electronics an upgrade is generally a replacement of hardware, software or firmware with a newer or better version, in order to bring the system up to date or to improve its characteristics.

Optical network unit version upgrade method and system

ActiveCN108733394AExempt from replacementLow costMultiplex system selection arrangementsTransmissionComputer moduleLine card
The invention discloses an optical network unit (ONU) version upgrade method and an optical network unit version upgrade system. The system mainly comprises a main control panel, a line card and an annular memory module disposed on the main control panel and the line card, wherein the annular memory module includes a writing task module for fragmenting file data of an upper-level device and writing fragments into a current-level device, a reading task module for reading the current-level data fragments and issuing the data fragments into a next-level device, a writing task scheduling module for controlling a writing speed and a writing position of the writing task module, and a reading task scheduling module for controlling a reading speed and a reading position of the reading task module;and the annular memory module is started when the ONU upgrade file cannot be completely stored in a memory resource of the main control panel or the line card. According to the optical network unit version upgrade method and the optical network unit version upgrade system, the writing and reading speeds are controlled by reasonably scheduling of reading and writing tasks so that remaining memories in the main control panel are not lower than a safety threshold value for normal running of the system, the ONU device is guaranteed to upgrade successfully when the ONU upgrade file cannot be stored in the main control panel or the line card; and the scheme is simple and low in investment.

Winding force sensor for hard metal wire, and winding force detection method

InactiveCN110608836AHigh degree of automationIncrease productivityTension measurementWinding machineHard metal
The invention discloses a winding force sensor for a hard metal wire, and the winding force sensor comprises a wire-passing guide wheel, a cantilever pressure sensor, and wire-pressing guide wheels, wherein the wire-pressing guide wheels are divided into left and right groups, which are respectively installed on support platforms on left and right sides of the cantilever pressure sensor. The invention also discloses a winding force detection method of the winding force sensor for the hard metal wire, and the method firstly makes the hard metal wire sequentially pass through the wire-pressing guide wheel on the left side, the wire-passing guide wheel and the wire-pressing guide wheel on the right side, starts the winding machine to tension and wind the metal wire that will generate downwardpressure on the wire-passing guide wheel and the detection axis of the cantilever pressure sensor, obtains the relationship between the pressure and winding force by the trigonometric function operation, and calculates the winding force of the metal wire, so that the real-time monitoring of the winding force of the hard metal wire during the winding process is realized, and the installation is flexible and convenient, which is suitable for the upgrade and reconstruction of large cable production equipment.

Online upgrading method and system for programmable logic device

InactiveCN113407223ARealize online upgradeSoftware engineeringProgrammable logic deviceEngineering
The embodiment of the invention provides an online upgrading method and system for a programmable logic device. The method comprises the following steps: receiving a target serial port signal carrying an upgrade file, which is sent by a CPU through a serial port pin group, through a second IO pin group; based on a mapping relation between a preset serial port signal and a bus signal, determining a target bus signal corresponding to the target serial port signal, the target bus signal carrying the upgrade file; and sending the target bus signal to a first bus pin group through a first IO pin group so as to write the upgrade file into a first programmable logic device through the target bus signal. On-line upgrading of the programmable logic device can be achieved under the condition that GPIO resources of the CPU are not occupied.
