Can assist quickly to investigate fault point during barrier, can popularization and application in the stored program controlled under same architecture.
Description of the drawings
Fig. 1 is the structural representation in this utility model embodiment.
Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, a kind of GPON networks MDU interface conversions and condition monitoring system in the present embodiment, including with it is many
Road MDU equipment is by the connected interface convertor of DB interfaces, state monitoring module, Arduino development boards, Zigbee data transmission terminals
Send with Fructus Rubi, the multichannel MDU telephone signal of GPON networks accesses the system by DB interfaces, through the interface convertor reality for concatenating
The direct conversion of line RJ11 interfaces is now arrived, user equipment, the signal input of state monitoring module are connected to by ordinary telephone line
Hold and be connected on the connection line of interface convertor and RJ11 interfaces, the signal output part of the state monitoring module is linked into
The signal input part of Arduino development boards, Arduino development boards determine user side telephone line states by change in voltage, with
The binary digit of 2bit represents different states, and such as " 11 " represent hook state, and " 10 " represent off hook state, and " 00 " represents broken string
State；The signal output part of Arduino development boards is connected with the signal input part of Zigbee data transmission terminals, and passes through Zigbee numbers
User Status are sent to Zigbee network, the signal input part of Fructus Rubi group and the signal output part of state monitoring module by transmission terminal
