Apply and safeguard that unit is pushed information in the mobile information platform 300 for safeguarding repair personnel, it is pre- with the overall process to fault message
Alert treatment.
It is configurating terminal that traffic lights safeguard repair personnel to mobile information platform 300, and failure is in for obtaining
The relevant operational state information of the crossroad traffic signal lamp of state, the operational factor for obtaining relevant traffic signal lamp, report maintenance
Repairing result etc..
Referring to Fig. 4, the road traffic signal lamp failure automatic early-warning system for constituting accordingly is respectively handed over by Real-time Collection crossing
Ventilating signal lamp running state information, and the information for just collecting carries out live data analysis treatment, to determine traffic lights
Carrying out practically state, once information can be distributed to traffic administration command centre by faulty phenomenon in the very first time, then by commanding
Signal is pushed to Traffic Warden Subteam by center, and notifies facility unit in time.Whole information flow can in public security network operation, without
Again construction network.
The road traffic signal lamp failure automatic early-warning system being made up of such scheme can fast and effeciently determine hair
Geographical location information residing for the road traffic signal lamp of the information that is out of order, once the traffic lights of crossing operation enter failure
State, can be uploaded to positional information and fault message by network carrier the command centre of vehicle supervision department in time, enter
Row collects and processes；Each area's level Traffic Warden Subteam is pushed information to by the command centre of vehicle supervision department again, then by area's level
Traffic Warden Subteam pushes information to corresponding means of transportation and safeguards unit, finally safeguards that unit is pushed information to by means of transportation
Safeguard in the mobile information platform of repair personnel, so as to the overall process early warning for realizing fault message is processed.
