Smart ODN system of low power consumption

摘要

The present invention discloses a smart ODN system of low power consumption, and the system is related to the ODN field and includes a smart management terminal, a master control management board, and several wiring management boards, where the smart management terminal is directly connected to the master control management board, and is also connected to the master control management board through the Internet and a mobile terminal, the master control management board is connected with several wiring management boards, each wiring management board includes a PMU and a PQU, which are independent from each other, the PQU is connected to a CPU of a wiring management board through a control line; the PMU is configured to collect and store information data of a port and communicate with the master control management board or the smart management terminal; the PQU independent from the CPU independently performs the query operation on a wiring port, and promptly obtains a port connection status. The present invention more than doubles operation time of a smart ODN management system, extends battery life of the whole system when a mobile power supply provides power for the system, shortens a time span taken by the system to respond to port changes, and improves operation efficiency of the system.

1. A smart ODN system of low power consumption, comprising:
a smart management terminal, a master control management board, and several wiring management boards, wherein the smart management terminal is directly connected to the master control management board, and is also connected to the master control management board through the Internet and a mobile terminal, the master control management board is connected with several wiring management boards, each wiring management board comprises a PMU and a PQU, the PMU and PQU are hardware units independent from each other, the PQU is connected to a CPU of a wiring management board through a control line and is independent from the CPU; the PMU is configured to collect and store information data of a port and communicate with the master control management board or the smart management terminal; and the PQU is configured to independently perform the query operation on a wiring port, and to promptly obtain a port connection status; wherein the PQU is implemented by a dedicated chip or by an FPGA through programming; wherein the PQU always performs query operation on a port when the wiring management board operates or sleeps, activates the PMU through a control line once finding that a port connection status changes, and requests information to be sent; wherein when no port changes when the system operates, the wiring management unit enters into sleep mode and only the PQU operates; when a port changes, the PQU activates the PMU, the PMU reports port change information to a management information system and automatically enters into sleep mode again; and wherein the flow of initiation and operation of the system is as follows: when the system initiates, an upper level device initiates wiring management boards one by one and makes them enter into sleep mode after the operation; after the upper level device finishes processing of all wiring management boards, identification and status reading of all devices are completed, then the upper level device enters into status A wherein the upper level device waits for an operation instruction and receives port change information; the wiring management boards except the PQU enter into sleep mode; the PQU constantly queries port status; the PQU continues query if no change is found; the PQU activates the PMU if a change is found, the PMU promptly updates port information contacts the upper level device and reports port change information; the wiring management board reenters into sleep mode after the port information is sent.
