The invention discloses an LVDS (
Low Voltage Differential Signaling) type
daisy chain communication method based on effective
signal detection, which relates to the technical field of communication, and comprises the following steps: S1, setting acquisition nodes, and connecting all the acquisition nodes in series by using a differential LVDS link to form a
daisy chain topological structure in a grading manner; s2, keeping the transceivers in the
daisy chain topological structure in a
sleep mode and keeping real-time detection; s3, when a high pulse
signal is detected, waking up the LVDS module to receive data; and S4, after confirming that the parameters take effect, generating a response packet, returning the response packet to the computer end, returning to a dormant state, and forming a communication transmission energy-saving
closed loop. According to the invention, through a mechanism of event triggering and local node participation, the
system is awakened when a high-pulse effective
signal is detected, so that the
power consumption overhead caused by that all nodes are always active in a traditional communication architecture is avoided; the method has the advantages of greatly reducing the average
power consumption of daisy chain data communication, improving the overall response rate of the
system and reducing the confirmation time
delay.
