example 1

[0030] Example 1: At the initial time, all power states are power supply states.

[0031] Until the incoming end 113 detects that no connection information is coming in through the receiving interface 13, the first transceiver device 11 switches the transmitting end 111 and the receiving end 112 to the power-saving state, thus causing no information to be transmitted to the second transceiver device 12. 收端122。 The receiving end 122. Therefore, the second transceiver device 12 also switches the transmitting end 121 and the receiving end 122 to a power saving state. At this time, the transceiver 11 and 12 cannot communicate.

[0032] Then, until the incoming end 113 detects that there is a connection message coming in through the receiving interface 13, the first transceiver device 11 will switch the transmitting end 111 and the receiving end 112 to the power supply state again, which will make the second transceiver device 12 because the receiving end 122 senses that there is an in...

example 2

[0033] Example 2: Please refer to figure 2 The communication device 2 also includes a monitoring interface 25, so that the second transceiver device 12 can know the working status of the first transceiver device 11 at any time. At the initial time, all power states are power supply states.

[0034] Until the incoming end 113 detects that there is no incoming connection message, the first transceiving device 11 switches the transmitting end 111 and the receiving end 112 to the power saving state. Then, the second transceiving device 12 learns through the monitoring interface 25 that the first transceiving device 11 is in the power-saving state, and the transmitting terminal 121 and the receiving terminal 122 are switched to the power-saving state.

[0035] Then, until the incoming end 113 detects that there is a connection message incoming, the first transceiver device 11 switches the transmitting end 111 and the receiving end 112 to the power supply state. Then, the second transc...

example 3

[0037] Example 3: Please refer to figure 2 The communication device 2 also includes a monitoring interface 25, so that the second transceiver device 12 can command the first transceiver device 11 to enter which power state. At the initial time, all power states are power supply states.

[0038] When the second transceiver device 12 commands to enter the power saving state, the first transceiver device 11 switches the transmitter 111 and the receiver 112 to the power saving state, and the second transceiver device 12 also switches the transmitter 121 and the receiver 122 to power saving status.

[0039] When the second transceiver device 12 commands to enter the power supply state, the first transceiver device 11 switches the transmitting terminal 111 and the receiving terminal 112 to the power supply state, and the second transceiver device 12 also switches the transmitting terminal 121 and the receiving terminal 122 to the power supply state.

Abstract

A communication system capable of adjusting consumed power is applicable for receiving a link message, and comprises a first receiver device and a second receiver device, wherein the first receiver device comprises a transmitting end and a leading-in end for receiving the link message, the second receiver device comprises a receiving end which can construct a communication contact with the transmitting end; and the power state of the transceiving device can be switch between power supply state and power-down state, so as to change the communication contact relation.

Description

Technical field [0001] The invention relates to a technology for reducing power consumption, in particular to a communication system with adjustable power consumption. Background technique [0002] The communication system is for signal delivery at any time, and a common way is to make the built-in transceiver device maintain power for real-time processing to avoid omissions and ensure transmission quality. For example: Regardless of whether the communication system receives a signal, the built-in transceiver device belonging to the physical (PHY) layer and the transceiver device belonging to the medium access control (MAC) layer both maintain power respectively to pass The serializer / deserializer (Serializer / Deserializer, SerDes) interface maintains communication between devices. [0003] However, the signal is not continuously delivered to the communication system. When the system is idle because it is not receiving signals, the power consumption of the built-in transceiver wil...
