Description
Technical field
The present invention relates to the railway interlocking communications field, particularly relate to a kind of railway information and collect and the field communicated.
Background technology
The operation of railroad train be unable to do without train control center, train control center wish in real time can and adopt the mode of redundancy to communicate to train data, then by system, the trackside performance element controlling the outdoor facilitys such as switch machine, signal, track circuit, cab signal is moved forward to the side of controlled device, and realize distributed AC servo system.Trackside communication extension set adopts dual CAN bus to communicate with asking of each control module.And power supply can also be provided by independently uplink and downlink bottle-neck section redundant power supply network to trackside performance element by power supply panel.Finally according to the feature of train operation, ites is desirable to interlock main frame and trackside equipment communicator have to be saved cable, reduce construction costs, reduces the advantages such as disconnection fault.
According to above problem, the present invention is compared to traditional approach in the past, and interlock access table generates more succinct and accurately, generates with consumption of natural resource when calling less, start and response time almost nil, therefore, the present invention has more advantage in interlocking.
Summary of the invention
The technical problem to be solved in the present invention is: more complicated signal and even more intelligent body bring more route Generating Problems to section and track switch.
For solving the problem, the invention provides following technical scheme: a kind of interlocking main frame and trackside equipment communicator comprise by host computer communication, trackside host computer communication, interlocking machine;
Trackside host computer communication is connected with switch machine, signal, track signal, and is connected with host computer communication; Both being connected communicates with parallel port by serial ports; Responser, dump device are directly connected with host computer communication; Digital and analog interface is connected with peripheral components such as the speed sensor in train, pressure sensor, crosspointer speed meter, mileage meters, speed data, and pressure data, crosspointer speed, mileage sends main frame to;
Terrestrial information is sent to receiver carried by automobile by wireless transceiver by responser, then delivers to main frame by interface.Various data during the train operation of dump device record, during for debugging locomotive and failure analysis, dump device is by interface data; Main frame carries out data exchange by CAN and locomotive;
Locomotive operating mode (various button information, Brake feedback information, handle position and direction switch information), is input to main frame by parallel port after level conversion.Main frame exports 3 way switch amount signals by parallel port, is respectively unloading, service braking, emergency braking.
Accompanying drawing explanation
Fig. 1 is system assumption diagram of the present invention;
Detailed description of the invention
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention will be described in detail.It should be noted that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention, the product that can realize said function belongs to equivalent to be replaced and improves, and is all included within protection scope of the present invention.Concrete grammar is as follows:
Embodiment 1: as shown in Figure 1: trackside host computer communication is connected with switch machine, signal, track signal, and is connected with host computer communication; Both being connected communicates with parallel port by serial ports; Responser, dump device are directly connected with host computer communication; Digital and analog interface is connected with peripheral components such as the speed sensor in train, pressure sensor, crosspointer speed meter, mileage meters, speed data, and pressure data, crosspointer speed, mileage sends main frame to; Locomotive operating mode (as various button information, Brake feedback information, handle position and direction switch information etc.), is input to main frame by parallel port after level conversion.Main frame exports 3 way switch amount signals by parallel port, is respectively unloading, service braking, emergency braking.
Train control center adopts two-node cluster hot backup redundancy of effort mode, identical by A, B two groups, independently control unit form, i.e. main frame and backup machine, be responsible for sampling to various extraneous information, and form the velocity mode curve between two ground dot-mode transponders according to the data of collection and the parameter of sets itself, when actual speed exceedes the limits value of modeling curve, export control signal and start corresponding brake equipment generation braking maneuver, speed is remained within the scope of requirement.If the CAN passage of main frame breaks down, can start the CAN for subsequent use of main frame, standby host still keeps standby host state, and when the two-way CAN of main frame all breaks down, standby host enters mode of operation as main frame immediately; When digital quantity I/O passage or the analog input/delivery channel fault of main frame, standby host can only be enabled.When main frame is in running order, standby host is in hot standby state, only has main frame to produce the control signal outputting to locomotive.Although standby host synchronized operation, it is the data that passive Receiving Host is sent, and according to the data of these Data Update oneself, it also produces control signal, but does not externally export.Namely main frame has control to system, and standby host does not have.Once main frame breaks down, standby host puts into operation immediately, becomes new main frame, and fault machine automatically exits host work state and keeps in repair; Train control center supports interface and the agreement of the communications such as RS485, CAN, MVB, carries out data exchange with the unit that tests the speed, ground dot-mode transponder.Terrestrial information is sent to receiver carried by automobile by wireless transceiver by ground dot-mode transponder, then delivers to main frame by RS485 interface.Various data during the train operation of dump device record, during for debugging locomotive and failure analysis, dump device is by RS485 interface data.System carries out data exchange by CAN and locomotive.Locomotive operating mode (as various button information, Brake feedback information, handle position and direction switch information etc.), is input to main frame by parallel port after level conversion.Main frame exports 3 way switch amount signals, is respectively unloading, service braking, emergency braking.Digital and analog interface, from the speed signal of vibration transmitter, a road braking reservoir pressure signal and road preserved signal input, also comprises train real-world operation speed, speed limit and mileage in addition.
This system is made up of monitoring equipment, workover rig, interlocking main frame, trackside performance element, safe communication system, power supply and supply network etc.Trackside performance element is made up of power module, trackside communication extension set, switch machine module, signal module, rail module, cab signal module etc.Safe communication system is made up of communication host, trackside communication extension set and communication network.Interlocking main frame communicates with adopting redundancy Rs 1 bus mode between communication host; Communication host communicates with trackside between extension set and adopts point-to-point slack to communicate;
The present invention designs interlocking main frame and mainly contains with trackside equipment communicator advantage: communicate with the state of various equipment with bursty state and according to the state of train according to actual operation, thus improves the Interlock Reliability at station.
