Document Type and Number:
WIPO Patent Application WO/2023/197443
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a signal transmission method, apparatus and device based on a drilling device, and a medium. Signal transmission is applied to a signal transmission system of a drilling device, wherein the signal transmission system comprises a master node and a plurality of slave nodes, and the master node communicates with the plurality of slave nodes by means of a 1-wire bus. The signal transmission method comprises: a master node sending to a designated slave node an instruction signal obtained by coupling a TTL signal with a data request signal, wherein the data request signal is a critical identifiable signal having the same cycle as the TTL signal, so as to ensure that a system can identify the logic level of the instruction signal and a 1-wire bus is occupied in real time; and the designated slave node receiving the instruction signal, performing decoupling on the instruction signal to obtain the data request signal, obtaining a reply signal on the basis of the data request signal, coupling the reply signal with the TTL signal to obtain a feedback signal, and sending the feedback signal to the master node.
