The signal driver module of signal controlling machine and detector are separately positioned, it may appear that detector docks needs with signal controlling machine
Special docking agreement, detection data cannot directly access monitoring backstage, monitoring backstage and control machine and respond speed to detection information
It spends slow etc..
To solve the above-mentioned problems, we are seeking always a kind of ideal technical solution.
Invention content
The purpose of the present invention is in view of the deficiencies of the prior art, to provide, a kind of integrated level is high, responds rapid traffic
Lamp fault detection and control system.
The technical solution adopted by the present invention is：A kind of traffic lamp fault detection control system, including detection and drive control
Module, main control module and control platform, wherein the detection is connect with drive control module with traffic lights, the detection and drive
Dynamic control module includes detection unit and drive control unit, and the detection unit is connected with the drive control unit, described
Detection communicates detection information to the main control module with drive control module；The main control module passes through the detection letter to output
Breath compares analysis, it is determined whether needs to carry out troubleshooting, when needing troubleshooting, the master control to traffic lights by setup program
Module sends control signals to the detection and drive control module, and the drive control unit is according to control signal to traffic
Lamp carries out respective handling, meanwhile, main control module will be detected is reported to control platform with processing data, provides dispatcher's reference arm
Mouth operating condition.When communication failure, the drive control list between the detection and drive control module and the main control module
Member is voluntarily handled traffic lights according to detection information.
Based on above-mentioned, it further include it is yellow dodge drive module, it is described it is yellow dodge drive module respectively with the main control module, traffic
Lamp connects, and when the main control module does yellow sudden strain of a muscle processing to failure, yellow glitch is sent to the Huang and dodges drive module, described
Huang dodges drive module driving traffic lights progress Huang and dodges operation.The measurement and control system dodges disposition multi layer control to the yellow of failure：
Drive module is dodged by Huang first and carries out yellow sudden strain of a muscle control；If Huang dodges drive module damage, main control module will export yellow glitch
Yellow dodge directly is carried out to drive control unit to control；When main control module and detection failure is communicated with drive control module, drive
Dynamic control unit can independently carry out yellow dodge and control.Multilayer Huang, which dodges control, can ensure the stability of the measurement and control system.
Based on above-mentioned, the detection unit includes current detector and frequency detector.Wherein current detector can be
Ammeter, frequency detector can be optocouplers, and the electric current and frequency of traffic lights carry out double check, and the reliability of fault detect increases
By force.
The present invention has substantive distinguishing features outstanding and significantly improves compared with the prior art, specifically, of the invention
Detection is integrated with detection unit with drive control module, and detection data can be directly accessed control platform, control platform and signal
Lamp control machine is to detection information fast response time.Furtherly, this system dodges processing multi layer control, troubleshooting to the yellow of failure
Reliability is stronger.Another step says that detection unit of the invention includes electric current and frequency detecting, the reliability enhancing of fault detect.
It has the advantages that integrated level is high, response is rapid and reliability is preferable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Below by specific implementation mode, technical scheme of the present invention will be described in further detail.
As shown in Figure 1, a kind of traffic lamp fault detection control system, including detection and drive control module, main control module
And control platform, further include yellow sudden strain of a muscle drive module, the yellow drive module of dodging is connect with the main control module, traffic lights respectively,
When the main control module does yellow sudden strain of a muscle processing to failure, yellow glitch is sent to the yellow sudden strain of a muscle drive module, the Huang flash drive
Dynamic module drive traffic lights carries out yellow dodge and operates.Wherein, the detection is connect with drive control module with traffic lights, the detection
Include detection unit and drive control unit with drive control module, the detection unit includes current detector and frequency detecting
Device.The detection unit is connected with the drive control unit, it is described detection with drive control module by detection information communicate to
The main control module；The main control module compares analysis by the detection information to output, it is determined whether needs by setup program
Troubleshooting is carried out to traffic lights, when needing troubleshooting, the main control module sends control signals to the detection and drives
Dynamic control module, the drive control unit carry out respective handling according to control signal to traffic lights, meanwhile, main control module will be located
Reason data are reported to control platform, provide dispatcher and refer to crossing operating condition；When it is described detection with drive control module with
Communication failure between the main control module, the drive control unit are voluntarily handled traffic lights according to detection information.
Embodiment 1
Traffic lamp on/off controls：When current detector detects that amber light electric current is excessive, detection and drive control module are by electric current mistake
Information carrying breath is sent to the main control module, and the main control module transmission turns off the light information to detection and drive control module, the drive
