Description
Technical field
The present invention relates to a kind of switching control in the electronics concentrator station.
Background technology
Switching control is used to be controlled at the driving of switch on the railway network and the position of monitoring switching track switch.Society proposes very high requirement to the fail safety and the safety in operation of switching control.For example happen to when train vibration influence passes through switch, must avoid because the disabler of switching control makes switch drive adjusted voltage.Relay is only used in the current signalling technique safety control that is used to load.It is believed that the airspace distance between the relay contact of opening is the effective isolation point, this in fact also determines through overtesting.Therewith correspondingly, people only set up known switching control with the relay technology.
The development of electronics concentrator station is along with in centralized function such as signal and demonstration, the computer technology of using in safety and the element control begins, develop into the control of carrying out an element by computing machine afterwards, develop into step by step in track clear signal (axle counting machine interior arrangement and timing point), use treater and microcontroller in signal control and in the interface card plate of parallel connection output and input.Because the switch group with the relay technology has high reliability, has no reason to carry out technology innovation up at present.
Yet the switching control convenience that constitutes with the relay technology need take up room greatly.Therefore wish the electronics concentrator station of the improved electronic switching control of exploitation usefulness.
Summary of the invention
Therefore task of the present invention provides a kind of electronic switching control, and the high security requirement aspect its startability in the concentrator station technology is satisfied in this electronic switching control.
This task is by solving according to the described switching controlling schemes of claim 1.Relevant with it preferred embodiment is described in the dependent claims.
According to suggestion of the present invention, relay contact and semiconductor switch are connected in series, like this advantage of two kinds of switchtypes is united.By the combination of electronic switch and mechanical contact, formed a nothing wearing and tearing switch with signalling technique performance.
Preferred embodiment be successively to operate two switches.When connecting, at first relay contact closure is connected load by semiconductor switch then.When disconnecting consumers, at first semiconductor switch disconnects, and opens relay contact then.Therefore relay contact moves at no current state, burn (wearing and tearing) can not occur.
Because operation does not have wearing and tearing, the electronic switching control setup has the very high life-span.By semiconductor switch, can be implemented on definite phase position and connect.Therefore when opening operation, reduce making current and induced voltage significantly, and reduced disturbing influence adjacent system.
Description of drawings
Below by means of unique accompanying drawing narration one embodiment of the present of invention.Accompanying drawing has been represented the interconnecting wiring diagram according to the switching control convenience dispatching device of the present invention's realization.
The specific embodiment
Switching control 1 is as central control unit, comprises that by model be the duplex computer system 10 that two microcontrollers of C167 are formed.Sort controller model and affiliated operating system used with access in other security application.
A binary channel interface 11a, 11b is connected with described electronics concentrator station, this connection for example can be adopted parallel interface (being applicable to ESTW Alcatel 6111 Lock Track), adopts redundancy CAN-interface (being applicable to ESTW Alcatel 6151 Lock Track) or employing to be applicable to the bus interface of the connection TTP-module (Time Triggered agreement) of ESTW Alcatel 6131 Lock Trac.Can also consider to adopt other multiple interfaces according to application requirements.LEDs on the front panel of described device is provided for the diagnosis function of fault search, or enters through the maintenance terminal on the serial interface.
Described switching control 1 is connected with switch actuating device 2 through a traditional four-wire interface, and this allows the connection of the minimum heart yearn realization switch actuating device of use, and the compatibility of realization and existing external device.Described switch actuating device comprises a three phase electric machine 211,212,213, is used for switch is moved to desirable final position.Contact 221-224 carries out closure or opening action by the position of suitable inspection loop 121,122 identification switches according to point tongue, and this checks that the loop is described in detail in the parallel patent application specification of declaring by same inventor.
Connect power supply voltage by semiconductor switch 131 and 132.Use the so-called IGBT-module (insulated gate bipolar transistor) by field effect transistor and bipolar transistor combination, each module comprises two IGBT for this reason, and one is connected on positive half-wave, and one is connected on negative half-wave.
If semiconductor switch is used on the big current return of control signal technology, so its isolation performance can only reach the semi-conductive punching voltage.When surpassing the punching voltage (by the over voltage of short time), flow through semi-conductive electric current and in quartz conductor, produce a high loss in efficiency.Because closed semiconductor switch of thermal overload short time, power supply voltage affacts in the load, so displacement might take place switch, this under any circumstance is unallowed certainly.
The problems referred to above are avoided like this according to the present invention, and relay WN and two quartz conductors 131,132 are connected in series.At lead L1, separately normally closed contact of relay WN and electronic switch (with the IGBT plug-in mounting) are cascaded on the current path of L2.On electronic switch, respectively dispose a variable resistance V1, V2, if when on the electronic switch of high resistance and the relay contact opened, the over voltage of pulse shape occurring, variable resistance V1, V2 can limit this over voltage, and therefore the over voltage that occurs on electronic switch can not be higher than the semi-conductive punching voltage.Described over voltage remains on the airspace of relay WN open contact apart from last.
Here relay use is monostable, the card form relay of forced guiding, and its contact is to replying by microcontroller.The position of WN contact bank can be read the contact by failure-free duplex computer system 10 all the time and be checked.
In order to reach the high life of relay contact, it is moved as isolator, that is to say that it determines current path, but and disconnect power, this is not born by semiconductor switch 131,132 with having wearing and tearing.Relay contact closure at first when connecting is connected load 211,212,213 by semiconductor switch then.When cutting off load, at first disconnect semiconductor switch, open relay contact then.By priority cutin relay WN and IGBT, can in each switching process, additionally check electronic switch.When cutin relay WN and IGBT when also disconnecting,, measure less than electric current at current converter I load and I open end.
Suddenly raise or in order to reduce induced voltage for fear of voltage, can preferably the switch motor be connected to voltage zero and pass through state, stop the switch motor during by state in described current zero.This realizes (electronic programmable electronics package) by ELDP 1111.When duplex computer system 10 discharged, the phase place correctness of 1111 pairs of changing voltages of ELDP was controlled.
In order to control the nominal position of switch, use two other relay R and L, they are the card form relay of forced guiding equally.Can to use switch in order being in operation, to be necessary to monitor all the time actual position.This information is by the switch nominal position by the response position relay with by checking that electric current flow regime on monitor current loop (60V) is formed.Electric current flows through the circuit series of the switch of monitoring voltage, and employing enters testing fixture 121 circulars and " enters " 122 for annunciator for annunciator " monitoring " and circular.All these modules realize with semiconductor technology.This can monitor pulsing operation with duplex computer.By means of the control by pulses algorithm that is fit to, cycle check monitor current loop publicly, the interruption status of heart yearn joint and voltage failure.Therefore be in operation and save conversion operations for the reality of obsolete switch.
Isolating transformer is used for the electricity of current path and isolates, and photoelectrical coupler is used for the electricity of signal path and isolates.
