Description
Technical field
The invention belongs to track traffic signal technical fields, and in particular to a kind of track traffic signal monitoring system.
Background technique
Track traffic signal monitoring system is to guarantee that traffic safety, the management of reinforcement signalling arrangement engaging portion, monitoring signals are set
Standby state, analysis signalling arrangement failure cause, assist trouble processing, instructs field maintenance, reflection to set at discovery signalling arrangement hidden danger
Received shipment quality, the important travelling facility for improving telecommunication and signaling branch maintenance levels and maintenance efficiency accomplish unified planning, unified real
It applies, with interlocking, occlusion, column control, TDCS/CTC, the systems Synchronization Design such as hump, construction, debugging, examination and open-minded.
Existing conventional rails traffic signals monitoring system (referring to fig. 2) is by two server tiers and a terminal device layer
Grade composition, two server tiers are respectively centre grade server and station level server；Terminal device level includes rail traffic
Ground and mobile unit in signal system；The signalling arrangement monitoring in this rank region may be implemented in two server tiers, together
When the access interface of Local or Remote is also provided.
Conventional rails traffic signals monitoring system met under the conditions of original technology at that time field of track traffic to signal
The primary demand of monitoring system also largely promotes the development and progress of rail traffic signal system.But with
The explosion type of track transportation industry develops, and conventional rails traffic signals monitoring system has exposed shortcomings, one net
The rapid development of the network communication technology, network environment and external electromagnetic environment etc. are increasingly complicated and changeable, the hair of disparate networks communication failure
It is raw that terminal device grade monitoring information is caused to be lost.Monitoring information loses so that monitoring information does not have integrality, to influence event
Site playback and accident analysis positioning after barrier eventually lead to the availability and maintainable reduction of entire signal system；Secondly
Terminal device is directly accessed station level server in conventional rails traffic signals monitoring system, and terminating stage can not provide signal system prison
Technical staff needs to tie up by the monitoring of station level server or centre grade server when surveying maintenance interface, system deployment or maintenance
Shield interface is analyzed and is handled to terminal device current state and historical failure, this causes system deployment and the efficiency of maintenance
No small influence.
Summary of the invention
To solve the above problem that conventional rails traffic signals monitor system, the invention proposes a kind of track traffic signals
Monitoring system.

Maintenance personnel quickly handles and eliminates equipment fault.
As the scheme of further improvement, the device level server in three server tiers is declined using high reliability insertion
Processor micro server, compact is exquisite, and also easier multiplicity, the cost of additional are very low great for mounting means
Sexual valence this.Embedded microprocessor micro server server is using the embedded system relationship type for meeting embedded system application
Database, data storage use raid-array technology, guarantee the stabilization redundancy and safety of data.Used insertion
Formula phylogenetic relationship type database has the characteristics that high availability, safety, cross-platform data management, concurrent and share and access；Branch
Local and remote SQL operation is held, while also supporting access mandate management and data encryption；Support ARM, MIPS, PowerPC and
X 86 processor, while Vxworks, QNX, freeRTOS, μ cos, wince, RT-thread, RTEMS etc. being supported commonly to be embedded in
Formula operating system.
As the scheme of further improvement, monitors between system server, uses high speed ether between server and terminal device
Wired or wireless mode may be selected according to actual environment demand in Network Communication, communication mode.Three level servers of monitoring system,
Centre grade server rank highest, station level server is secondly, device level server rank is minimum.High-level server passes through credit
Long-range SQL mode of operation access low level server realize that fast and safely data difference is synchronous；Low level server is based on
Local data configuration file can carry out the other data filtering of the same level and processing, and it is same to avoid the invalid nonsignificant data of uplink
Step；Low level server local data configuration file can pass through high-level server authorization or local manual type configuration.
As the scheme of further improvement, three level servers all provide the access interface of the Local or Remote of credit, base
In remote interface can be convenient each jurisdiction by level region of realization signalling arrangement monitoring, based on local interface system deployment and
Maintenance personnel can safely and efficiently implement system deployment and maintenance.
As preferential, embedded microprocessor micro server uses the embedded scheme of ARM+FPGA.
As preferential, centre grade server and station level server are equipped with dedicated display device, and device level server is not required to match
Standby dedicated display device.
Compared with prior art, the present invention has the following technical effect that
A kind of track traffic signal monitoring system main innovation point:
1, the present invention use three tier server framework, increase device level server relative to legacy system, make entirely be
System has the ability of three-level monitoring, diagnosing, improves the efficiency of system deployment and maintenance.Simultaneously because device level server portion
Administration is in terminal filed, technology people when can provide signal system monitoring and maintenance interface, system deployment or maintenance for terminal device grade
Member directly can be analyzed and be handled to terminal device current state and historical failure, and system deployment and maintenance are substantially increased
Efficiency；Monitoring information will not be caused to lose because of system overall network failure simultaneously, the effective guarantee integrality of information；
2, device level server uses high reliability embedded microprocessor micro server, and compact is exquisite,
Mounting means also easier multiplicity；Device level server disposition embedded system relevant database, realize with
The perfect matching of traditional desktop server database interface；The offer of device level server is similarly awarded with conventional desktop server
The interface locally or remotely accessible of letter.
