213) after the completion of selection confirms, if agreement successful match, agreement successful match is prompted on interface, if selection has confirmed
Cheng Hou, agreement mismatch, then prompt agreement matching unsuccessful on interface, and return to step 212) it reselects.
9. a kind of intelligent network according to claim 7 joins motor road top-cross messenger method for converting protocol, which is characterized in that
The step 3) specifically includes following steps：
When signaling protocol conversion equipment connect obstructed with traffic signal controlling machine, digital independent, tool are carried out by hardware port
Body is：
301) after the serial ports or network interface that traffic signal controlling machine is connect with signaling protocol conversion equipment interrupt, signaling protocol conversion
Device is switched to hardware data acquisition mode；
302) signaling protocol conversion equipment directly reads signal modulating voltage and electricity by voltage acquisition unit and current acquisition unit
Stream information；
303) the local timing scheme of traffic signal controlling machine is directly acquired；
304) local timing scheme, signal lamp voltage and current information data are summarized and the agreement for carrying out a variety of supports turns
It changes, transformed data is packaged according to data protocol；
It is synchronous to pass through serial acquisition unit and hardware end when signaling protocol conversion equipment connect normal with traffic signal controlling machine
Mouth carries out digital independent, specially：
311) when signaling protocol conversion equipment connect normal with traffic signal controlling machine, signaling protocol conversion equipment is switched to string
Mouth acquisition mode；
312) by serial acquisition unit read the working method information of traffic signal controlling machine, timing scheme, phase state with
And lamp group and terminal information, current state and count down information；
313) by the working method information of traffic signal controlling machine, timing scheme, phase state and lamp group and terminal information, when
Preceding state and count down information are summarized and are carried out the protocol conversion of a variety of supports, by transformed data according to data protocol
It is packaged.
10. a kind of intelligent network according to claim 7 joins motor road top-cross messenger method for converting protocol, feature exists
In the step 4) specifically includes：
Signaling protocol conversion equipment passes through equipment heartbeat, signal lamp data, device status data, failure logging and operation log
Communication module unit be actively sent to large data center and carry out cycle covering and display, large data center pass through communication module list
Member asks required data, including timing scheme, failure logging and operation log to signaling protocol conversion equipment.
