Description
Technical field
The present invention relates to tunnel monitoring technical field, more particularly to a kind of equipment monitoring system based on hardware redundancy.
Background technology
In tunnel monitoring field, most of the monitoring system based on PLC is the CS1D types PLC and master using Japan OMRON
To be directed to vcehicular tunnel, be characterized in PLC system as a subsystem among vcehicular tunnel comprehensive monitoring system, using point
Cloth structure, one section of highway corresponds to 1 set of CS1D type PLC system, and each subsystem function is：1st, some zone detection is collected
The information of the information, the generally detection such as CO detectors, visibility detector and wagon detector of equipment detection；2nd, ventilation control
System：Blower fan is controlled according to situations such as CO concentration, the volume of traffic, number of units, blower fan rotation direction, the fortune for such as controlling blower fan to put into operation
Row time etc.；3rd, Lighting control：According to the illumination controlled inside and outside the hole detected situations such as light intensity data, day and night in tunnel
Illumination in system, regulation entrance and hole；4th, electrical substation monitoring：Power supply running status and fault status to tunnel transformer station is entered
Row monitoring.
And vcehicular tunnel comprehensive monitoring system is Three Tiered Network Architecture from top to bottom：Management information net, equipment control net, showed
Field device net, and using centralized management, decentralised control strategy.Wherein PLC subsystems provide for vcehicular tunnel comprehensive monitoring system
The field device information of bottom, collectively forms and sets with video management subsystem, information issue subsystem, fire alarm subsystem etc.
Standby key-course, each subsystem has itself field apparatus net, and subsystems give the tunnel in management information stratum reticulare to integrate
Emergency command is intervened in management platform interaction data, by road tunnel comprehensive monitoring system log history data and generation emergency
Strategy, generates the form of data and event and interacts in real time or go through with municipal public administration mechanism (Department of Communications, fire station etc.)
History information.
Current vcehicular tunnel comprehensive monitoring system Shortcomings and defect：
1st, Japanese OMRON complete control technology is employed, is not required to separately develop, but must be in each distributed controll
Section configures the PLC system that a whole set of includes redundancy CPU, power supply, networking component and I/O cards, causes whole PLC field networks layer
Device hardware is more and cost is high.Can also with PLC whole systems in the case where I/O equipment is various for each section of vcehicular tunnel
Receive, but actually each section I/O equipment amounts simultaneously less (are less than 256 passages), therefore a whole set of PLC system price height of configuration,
Engineering economy is poor.
2nd, the special monitoring software of vcehicular tunnel of the supporting customization of Japan OMRON vcehicular tunnel comprehensive monitoring system, but
Just because of being the special monitoring software of vcehicular tunnel, systemic openness is lost and flexible while realizing and simplifying configuration application
Property, and it is same for the angle of engineering, although use mark without the interface protocol of self-developing software, but sub-system
Quasi- interface and agreement, flexibility is not strong；Secondly, the special monitoring software price of the vcehicular tunnel is high, it is impossible to realize engineering economy；
Finally, the special monitoring software of the vcehicular tunnel is developed for vcehicular tunnel, and the electromechanical equipment of vcehicular tunnel and Under-cross tunnel
It is entirely different to monitor emphasis, if not also being suitable for Under-cross tunnel without relevant configuration and secondary development.
