Abstract

The invention provides a data upgrading method and system, and the method comprises the steps: receiving a mode switching instruction broadcasted and transmitted by a control end when a circuit moduleneeds to carry out the data upgrading, and switching an operation mode into an upgrading mode according to the mode switching instruction; wherein each circuit module has different identification numbers; according to a preset receiving sequence, receiving an upgrading data packet sent by the control end based on the fragmentation transmission strategy, the upgrading data packet comprising m pieces of data packets; when the current circuit module receives the upgrading data packet; judging whether the upgrading data packet is an own upgrading data packet or not according to the identificationnumber of the target circuit module carried in the upgrading data packet; if the upgrading data packet is not the own upgrading data packet, forwarding the upgrading data packet to an adjacent circuit module according to a preset forwarding strategy until the upgrading data packet is matched to the target circuit module; and when the target circuit module receives the upgrading data packet, performing data upgrading by utilizing the upgrading data packet.

Description

technical field [0001] The invention belongs to the technical field of petroleum drilling, and in particular relates to a data upgrading method and system. Background technique [0002] With the increasing difficulty of reservoir development, reservoir development forms and reservoir geological conditions and other factors, the requirements for drilling technology are getting higher and higher. Due to its high drilling precision and high economic benefits, rotary steerable drilling technology is favored by drilling workers. . [0003] Rotary steerable drilling is generally realized by downhole rotary steerable tools. The rotary steerable tool includes multiple circuit modules, and each circuit module has an independent controller. In order to ensure drilling accuracy, each circuit module needs to be updated and debugged. [0004] However, in the prior art, not all circuit modules have external mechanical ports, so the tool can only be disassembled when performing data upgr...
