Description
Technical field
The present invention relates to a kind of means of voting based on binary channels voting system.
Background technology
Meeting voting formula experienced from applaud, raise one's hand to using electronic voting system evolution process.
The common display form of electronic voting system is that a uninscribed voting machine is set in face of each representative, is had above
" agree with, oppose, waiving the right " three buttons, after representing button, the data of each electronic voting machine in meeting-place can be controlled by deciding by vote
Device processed, which collects, is forwarded to main control computer, and after main control computer counts to result, voting result is included in meeting-place
In electrical screen.
Generally speaking, the framework of voting system is substantially use " voting machine-voting controller-main control computer "
Form.Voting machine in meeting-place by special communication cable is connected to voting controller after being connected by the mode of handing in hand, and decides by vote
The control operations such as controller carries out system configuration to N number of voting machine on this link, order is sent, voting information gathering；Together
When, after voting machine quantity reaches certain scale just a plurality of voting machine link must be controlled respectively using multiple controllers.M
Controller controls M × N number of voting machine, and M controller converges to string further through serial port connecting wire cable or Ethernet connection cables
Mouth convergence device or Ethernet switch, and finally communicated with voting main control computer.Run on voting main control computer
Voting primary control program major function be exactly whole voting system is configured, send voting order, collect voting machine by
Key information, display proposal voting result etc..
The structure of conventional electrical voting system is simultaneously uncomplicated, but electronic voting system with we it is daily it is middle use it is other
The different place of system is that its occasion applied all is often in great, serious conference process, if in voting process
In, system jam, then, it is not merely that have impact on being normally carried out for meeting, it could even be possible to making participant to meeting
Voting result produce distrust, in turn result in the severe political fallout of comparison.Therefore, the operation of electronic voting system is not only
It is required that efficiently and accurately, its requirement to the stability of a system, reliability is also high.
Therefore, the global reliability tool for improving electronic voting system is of great significance.At present, in general electronics
Voting system is more to carry out related work, allusion quotation in terms of main control computer, voting controller, voting machine and its connection cables etc. four
The mode of type and its weak point are as follows：
First, " annular is handed in hand " connected mode is used in voting machine connected mode.The voting machine of each link it
Between connected using mode hand in hand, when occur in the link Single Point of Faliure (such as broken cable or a certain seat voting machine occur therefore
Barrier) when may result in the disconnecting of the follow-up voting machine of whole piece link.To tackle this kind of failure situation, " annular hand can be used
Handle " connected mode connection voting machine, is to draw a connection cables and table again on the end voting machine of each link
Certainly controller connects, and link is formed a ring.This annular connected mode can avoid because of Single Point of Faliure to a certain extent
Caused by system overall failure, but can not avoid being when multiple voting machine failures occur for system or controller breaks down
System overall failure.
Second, by the way of cold standby or hot standby controller.This is also a kind of conventional emergency preplan, is each of the links
Increase a backup controller.Backup controller can use cold standby mode to use hot standby mode.If using cold standby
Mode：When a certain controller breaks down, then its corresponding cold standby controller is enabled temporarily.Meet an urgent need and ring when breaking down
Should be cumbersome, take longer, easily error.On this basis also have it is a kind of reduce the emergency processing time way, be exactly
Controller backup mode is changed to hot standby mode.Specific practice is exactly to use the distributor customized and switch by spare controller
It is connected in system, currently used controller is selected by switch, when a failure occurs, will will be currently by switch
The controller used of uniting is switched to spare controller.This mode can save processing during failure response to a certain extent
Time and step, but due to introducing " distributor " and " switch " two key node equipment again, be the equal of and draw
Enter trouble point, when " distributor " and " switch " breaks down, will also result in global fault.Meanwhile both modes
The system overall failure brought when all can not solve main control computer failure.
Third, the standby main control computer of increase, and failover is carried out using Two-channel switching equipment.Under this framework,
When main control computer breaks down, system can be switched on standby main control computer using Two-channel switching equipment and continued
Carry out subsequent operation.This scheme can solve the problem that the situation of the system failure caused by main control computer breaks down, but its shortcoming
It is that switching needs to carry out manual operation, and adds trouble point, Two-channel switching equipment easily becomes the weak ring of system in itself
Section.
Fourth, increase other set voting system can be with primary system as back-up system, newly-increased standby voting system
System uses different implementations.Such as pass through the voting machine of design specialized on the multimedia terminal for possess touch screen function
Software realizes voting function, and multimedia terminal deployment and traditional touch-tone voting machine be all deployed in participant's desktop, usually two
Set system each completes different functions, can be pressed on multimedia terminal with information, tradition such as display conference file, proposal titles
Keyed voting machine completes proposal voting function.When the failure of traditional touch-tone voting machine can not be in use, can be by multimedia
Terminal control computer sends instruction, the multimedia terminal in meeting-place is entered voting procedure, voting procedure mould on the touchscreen
Intend " agreeing with ", " opposition ", " abstention " three buttons, participant expresses wish by the button on point touching screen and carries out proposal
Voting.So as to realize the lasting progress of meeting.This scheme can solve the problem that when any failure occurs for primary voting system, it is impossible to
Persistently ensure the situation that meeting is carried out, but there is also two aspect problems in actual mechanical process, one be due to enable it is standby
Participant requires transformation into the progress proposal voting on the virtual key of touch-screen after system, rather than under normal circumstances in reality
Carried out on body button, this just must specially be illustrated by meeting presider in conference process to such case, if primary
System is the failure that occurs during proposal voting, then also needs to again be decided by vote to having voted on the bills and proposals, this be also required into
Row specified otherwise.In a word, the specified otherwise of host all can extreme influence meeting normal flow, give meeting affairs organization work band
Carry out extreme difficulties；On the other hand it is that this system-level switching is also to be operated by operating personnel, nervous shape at the scene
Also there is the possibility of human error under state, and participant also easily makes a fault when putting to the vote, such as not in void
Intend deciding by vote on button, and be still on primary voting machine and put to the vote.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the invention provides a kind of voting based on binary channels voting system
Method.
The technical solution adopted for the present invention to solve the technical problems is：A kind of voting based on binary channels voting system
Method, comprise the following steps：
Step 1: when starting voting, A channel main control computer is sent to channel B main control computer starts voting order；
Step 2: A channel main control computer and channel B main control computer are respectively to the respective channel of dual channel controller
Voting order is sent, into voting state, each delegate participating in the conference carries out button voting；
Step 3: the A of dual channel controller, channel B collect key information respectively, and respectively to A channel main control computer
Sent with channel B main control computer；
Step 4: A channel main control computer and channel B main control computer receive the voted data that respective passage is sent
While be transmitted to other side；
Step 5: A channel main control computer and channel B main control computer respectively enter to the voted data of two passages
Row processing, then merges the data of two passages, invalid key assignments is replaced with effective key assignments, finally by the number after merging
According to being counted and shown；
Step 6: when terminating voting, A channel main control computer is sent to channel B main control computer terminates voting order,
Then A channel main control computer and channel B main control computer are sent to the respective channel of dual channel controller respectively terminates voting
Order, this voting terminate.
Compared with prior art, the positive effect of the present invention is：
1. compared with traditional " annular is handed in hand " connected mode, present system eliminates the Single Point of Faliure of voting machine unit.
" annular is handed in hand " although in connected mode occur a voting machine failure after can avoid to a certain extent because
System overall failure caused by Single Point of Faliure, but the integrality of system is still destroyed, and system will lack a seat voting machine.
And the system is using binary channels voting machine, equivalent to there is two voting machine concurrent workings at the same time in same position, when
After one goes wrong, another unaffected, remains able to normal work, and system integrity is unaffected.
2. compared with the modes such as traditional cold standby controller mode, cold standby computer, when the system reduces failure generation
System handover operation, avoid human error.
In systems to key core equipment, such as：Controller and main control computer, the mode of cold standby is carried out, although energy
It is enough when these nucleus equipments break down by manual switching to cold standby equipment, still, on the one hand, this process take compared with
It is long so that meeting normal procedure is affected, or even the situation that requirement participant goes back upon a vote to same proposal, meeting occurs
It is very bad to discuss effect；On the other hand, when disposing such case at the scene, the pressure of staff is very big, it is possible to can go out
The situation of existing operational error so that emergency processing fails, it is impossible to solves the system failure in time.And these crucial cores of the system
Heart equipment is all while concurrent working, failure need not switch over operation when occurring.Do not made for the normal flow of meeting
Into influence, participant will not perceive the generation of failure, and the button operation that participant has made also all has been received by the system
Arrive, be not in the situation for needing to go back upon a vote to same proposal.
3. compared with traditional hot standby controller, hot standby main control computer mode, hardware device that the system does not increase newly
Trouble point, the control logic of system software are also relatively simple.
Traditional hot standby controller and hot standby main control computer mode are required for introducing switching equipment in systems, so as to
Stand-by equipment is can switch to when core host apparatus breaks down, the switching equipment newly introduced is actually in systems
New trouble point is introduced, the stability and reliability of its own have great shadow to the overall stability of system and reliability
Ring；Simultaneously because active and standby two sets of data source or data processing equipment be present, this kind of system needs the extremely complex number of design logic
According to, control synchro system, cause software systems complexity too high, resistance to overturning, reliability are relatively low.
4. form separate main preparation system as back-up system with traditional increase other set voting system
Scheme is compared, and this programme can preferably merge two sets of independent voting systems, when being broken down on single passage, without
Carry out system switching, the button voting formula of participant do not make any changes, and are operating and are using upper when avoiding switching system
The error situation being likely to occur, while participant will not perceive the generation of failure, without changing conference flow, Neng Goubao
Demonstrate,prove the fluency of meeting procedure.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the system architecture schematic diagram of the present invention；
Fig. 2 is the structural representation of binary channels voting machine.
Embodiment
A kind of voting system based on double-core dual link, using total system dual link architecture design hot standby in real time.Such as
Shown in Fig. 1, including A, channel B main control computer, A, channel B convergence switch and at least one dual channel controller are described double
The binary channels voting machine that channel controller connects hand in hand with several connects；The A channel main control computer, A channel convergence
Interchanger, the A channel of dual channel controller, the A channel of several binary channels voting machines connected hand in hand are in turn connected to form
Decide by vote link A；The channel B main control computer, channel B convergence switch, dual channel controller channel B, several pull
The channel B of the binary channels voting machine of hand connection is in turn connected to form the voting link B independently of voting link A.
The A channel convergence switch and channel B convergence switch are connected with core switch.The core exchanges
Machine is connected with C network switch.The C network switch is respectively with main meeting management work station, for meeting management work station, main number
Connected according to storehouse server, standby database server, master network printer, the standby network printer.
Binary channels voting machine connection of handing in hand refers to：The A channel of dual channel controller provides parallel defeated in four tunnels
Exit port, each output port can connect 128 voting machines.Each port is drawn by special eight cores connector decides by vote
Cable, and be connected by general aviation connector with the A channel arrival line of first binary channels voting machine, first voting machine
A channel egress line again be connected with the A feeder connection lines of second binary channels voting machine, by that analogy, until second from the bottom
The A channel egress line of individual binary channels voting machine is connected with the A channel arrival line of last binary channels voting machine.Such A channel
Voting machine, which realizes, to be connected hand in hand.What the connection hand in hand of same channel B voting machine was also realized in.
RS485 bus communications are used between dual channel controller and binary channels voting machine.In communication process at controller
In whip hand, voting machine is in passive position.All voting machines of order that controller is sent to voting machine can be received by,
The order of controller is divided into two classes, and one kind is global command, that is, requires the order that all voting machines will perform, such as：Start
Voting, stop voting, the reset of all voting machines etc., another kind of is specific order, that is, requires the order that single voting machine performs,
Such as number order, unit reset command etc. are received, this kind of order can specify the unique address code of the voting machine.Voting machine receives control
After device order processed, order can be parsed.If it was found that the order is global command, directly start to perform order；If it was found that
The order is specific order, then the unique address code of oneself is compared with the address code carried in order, is compared consistent
Then perform, it is inconsistent, ignore.Controller is that the serial communication between voting machine is realized by this communications protocol.
Typical communication process is as follows, after voting controller receives " starting to decide by vote " order that main control computer is sent, first issues one
Global command, it is desirable to which all voting machines enter voting state；Voting machine receives and indicator lamp is set into flicker state after the order,
Start to read key value；Once some button is pressed, voting machine then records the key assignments, then stops flashing light, makes lamp normal
It is bright；In sequence controller is polled receipts number, i.e., after all voting machines start to read key assignments in the way of " roll-call "
Each voting machine for being connected to controller sends the specific order of " receipts number ", will just be received by the voting machine put to name
Key value information sends controller to.(if the now also non-button of voting machine, the voting machine can return to its station number control
Device).Communicated between dual channel controller and main control computer using TCP/IP.
The institute in binary channels voting machine, dual channel controller, PC, interchanger, display device and system in system
There are linked circuits, be double copies.Equivalent to there is the concurrent working simultaneously of two sets of voting systems, equipment on any bar passage or
Line failure, the normal work of another passage is not interfered with, and manual switching need not be carried out, it can be ensured that meeting
Uninterrupted be normally carried out.
The effect of core switch is exactly that the equipment of A channel and the equipment of channel B can be interconnected.
In terms of electric power system, whole supply network is divided into tri- different sub-networks of A, B, C by us.Wherein wrapped in A subnets
The electrical equipments such as the A modules of A channel main control computer, A channel interchanger, dual channel controller are contained, B are contained in B subnets
Passage main control computer, channel B interchanger, the electrical equipment such as B modules of dual channel controller, contain in C subnets other
There is no the equipment or work station of task during voting.C subnets include active and standby database server, active and standby meeting management
The equipment such as work station, active and standby printer.All data messages of system are stored in active and standby database server；Active and standby meeting
The effect of business management work station is that meeting message is added before meeting, deleted, is changed, and generates, preserves, type list after the meeting
Certainly result, that is, the data in active and standby database server are managed.Equipment in C nets is all before meeting or after the meeting
The equipment used.For simplified system architecture in conference process, to database and network when reducing voting system operation as far as possible
Degree of dependence, avoid the normal operation of database or network fault influence voting system, voting main control workstation is in meeting
Just all data needed for system are all read in A, channel B main control computer before beginning, not visited again during meeting voting
Database server, caused voting result data are also first stored in A, channel B main control computer during meeting voting,
Unify all voting results being stored in database service again not by network storage into database server, after meeting adjourned
Device.These three subnets are respectively derived from different power supply units, the purpose so divided be avoid because certain all the way power supply occur therefore
Barrier, nor affect on the ability to work of whole system.
In terms of communication network, whole network also divide into tri- communication subnets of A, B, C by us.
Single voting machine in system has the independent voting units of A, B two, and the work(of voting machine can each be implemented separately
Energy.After A, B voting unit in multiple voting machines is connected hand in hand each via voting client cables, table is respectively enterd
Certainly controller, form the data link of A, B two.Decide by vote in controller, also there are two independent voting control units, respectively
For controlling the data link of A, B two.A, the B both links that are managed of voting controller, by network cable respectively with voting
Control main frame A is connected with voting control main frame B, just forms two real-time onlines, mutually redundant complete voting link.
Supporting network as system, it is intended that introduce a set of network architecture, make in real time to exist in voting system
Line, mutually redundant A, B both links, on the premise of establishing one's own system, realize zone isolation, classical network can be defendd to attack,
Strengthen the robustness and stability of whole network system.That is, in the case of single link failure, do not interfere with another
The stability and reliability of bar link.
Often quickly, the voting process of a proposal will be complete within more than 10 seconds time for rhythm during actually deciding by vote
Into process is decided by vote in each proposal, is required for operating personnel to perform " display proposal " according to the chair words of host, " start table
Certainly ", the sequence of operations such as " terminating voting ", " display voting result ".In order to ensure the voting system running status of two passages
It is consistent with system data, two main control computer operation rhythm should be as consistent as possible.If distinguished by two operating personnel
It is difficult to ensure operational consistency for a long time to operate this two main control computers to be.Therefore, in system design, A channel master control meter
Communication and command interaction are needed between calculation machine and channel B main control computer.Specific algorithm is as follows.
When starting voting, first sent to master control B of master control A starts voting order, and then master control A and master control B corresponds to respective
Controller send voting order, into voting state；Controller starts to collect voting machine key information, and is calculated to master control
Machine is sent；Master control A receives the voted data that controller A is sent, and master control B is relayed to while receiving data, accordingly,
Master control B receives the voted data that controller B is sent, and B points of master control A, master control A and master control are relayed to while receiving data
The other data to controller A and controller B are handled, and then merge controller A and controller B data, are merged
Principle be that effective key assignments replaces invalid key assignments, finally the data after merging are counted and shown；When terminating voting,
Master control A first sends to master control B and terminates voting order, and then master control A and master control B sends to each self-corresponding controller and terminates table
Certainly order, this voting terminates.
First, binary channels voting machine
Binary channels voting machine has two processing units and each independent communication link, and two processing units share one
Individual key control panel, the one-touch action of a representative, can be gathered simultaneously by two cores.The structure of binary channels voting machine
As shown in Fig. 2 including DPDT button, button circuit board and two-channel circuit plate, wherein：DPDT button is three,
On button circuit board, be used separately as " agree with, oppose, waiving the right " three voting buttons, button circuit board by arrange pin with
Two-channel circuit plate is connected, and three buttons are delivered separately on two-channel circuit plate with caused two-way push button signalling
Two core processing units are handled respectively.
Using serial communication mode hand in hand between single core voting machine in conventional voting system, if certain seat is decided by vote
Device is broken down, and all follow-up voting machines in its residing link will be caused not work.If voting machine core running unit
Possess redundancy backup, even if certain seat voting machine breaks down, also do not interfere with the normal work of voting machine follow-up in its residing link
Make, ensure the normal operation of system.Also, because both links are completely independent work, broken down in any one link,
Either controller failure is interrupted or decided by vote to voting machine core running unit failure or communication line, all without another of influence
The normal work of link.
(1) DPDT button and keypad
Although voting machine possesses two core running units, for participant, its key panel operated can only
It is one.We use DPDT fine motion button, and one-touch action can produce two signals simultaneously, for two votings
Device core gathers.
Three DPDT buttons are welded on button circuit board, button circuit board presses button with caused two-way
Key signals are received and handled by two sets of separate circuits respectively, and this two circuits are separate, without any company
Connect road.Two circuits are connected by the 4 pin signal connecting contact pins of the right and left and the two-channel circuit plate of lower section respectively.
(2) double-core running unit is hot standby in real time
Voting machine unit uses the collection in real time of two sets of independent core running units and processing key information, two cores
Concurrent working, even if a certain core running unit breaks down, data transmit-receive and the processing of another unit are not interfered with yet, and
And participant will not perceive the generation of failure completely, it can be ensured that conference agenda is smoothed out.
Two core processing units are devised on binary channels core processing circuit plate, two core processing units do not have yet
Any connection physically.Two core processing units connect the key information on socket acquisition keypad by signal respectively,
And carry out key information processing.Each core processing unit devises two " voting client cables connection sockets ", respectively with respectively
Connected hand in hand from the voting client cables on passage.The effect of voting client cables is to establish and voting controller
Communication connection, it is controlled order and the transmission of voted data communication.
Voting client cables refer to the cable specifically for voting system design and customized production, fully examine in design
Consider power supply, the load capacity of signal and electromagnetic shielding and antistatic protection function, core number, line footpath to cable, connection side
Formula etc. all takes into full account have special core to be used as conduct static, and whole piece cable tie has metal screen layer, realizes special core
It is special, fully ensure that electrostatic protection and the anti-electromagnetic interference capability of cable.
In terms of engineering wiring, the cable color of system A/B both links will be distinguished substantially, and one is black, separately
One is white.The connector type selecting of both links, which have also been made, to be taken into full account, a strip adoption metal aviation plug, one is adopted
With the modern designs of plastics pressure head.Both links overlap joint is it also avoid while obvious distinguish.
(3) indicator lamp logic control is carried out using optocoupler
" agree with, oppose, waiving the right " on voting machine panel to be respectively arranged with key indicator lamp, three buttons at three buttons
Indicator lamp is reminded participant to perform corresponding action, served very heavy by the switching of states such as " flicker, Chang Liang, extinguishings "
The channeling wanted.Showing for LED status must be clear.
Two core cells of voting machine are all each equipped with one group of indicator lamp, but the key indicator lamp showed on panel
Only one group, therefore, synchronization, the indicator lamp that can only have a voting machine core can be carried out showing for state, another
Indicator lamp in core should be in OFF state.
Because two cores of voting machine are physically completely self-contained, therefore, we use optocoupler technology, are used for
Logical communication between two voting machine cores, and formulated a set of corresponding logic judgment rule, it is ensured that no matter in positive reason
Under condition, or in the case of some voting machine core exception, the indicator lamp of voting machine all can correctly show due all the time
State, avoid causing to perplex to representative.
Under normal circumstances, indicator lamp, which extinguishes, represents that the voting machine is not entitled to use；Indicator lamp often bright expression voting
Device is standby；Indicator lamp flicker represents that the voting machine is in voting state, and now after button, key information can be
System receives.
Respective independent operating between two cores of AB of double-core voting machine, without physical connection, is adopted between two cores
The running status of the mutual detecting other side of optical signal is carried out with photoelectric coupled device, carries out the logic judgment of correlation.Concrete mode
It is that a flag bit is devised in A cores, when A enters voting state, this flag bit (bit) can be put 1；When B cores are entered
When entering to decide by vote state, it can be 1 by the flag bit of optocoupler signal detection to A cores, show that A cores have started to normal work, this
When B cores indicator lamp would not flash；If B cores detect that the flag bit of A cores is 0, show A core running statuses
Incorrect, now, the indicator lamp of B cores starts to flash.In this way it is ensured that after voting is started, have and only one group of instruction
Lamp is flashing.
Two cores of AB of double-core voting machine are each provided with one group of indicator lamp, and the state of indicator lamp is only by corresponding fortune
Row core controls, will not cross-over control.Illustrate in two kinds of situation below：
First, under holding state, entitled voting machine, two cores of AB can light respective indicator lamp；Power is not assigned
Voting machine, the indicator lamp of two cores of AB all extinguishes.
Second, under voting state, A cores receive start voting instruction after, indicator lamp can enter line flicker state.B cores
Receive after starting voting instruction, can actively be delayed 100ms, and within this 100ms, B cores can pass through optocoupler signal detection A cores
Whether work is normal, if A core works are normal, B cores indicator lamp will not flash, if A core works are abnormal, B
Core indicator lamp can flash.
The purpose for the arrangement is that ensure all the time, after starting voting, only one group of indicator lamp flicker, if two cores of AB
Indicator lamp all flash, then can form double sudden strain of a muscle states, puzzlement is brought to user.
2nd, binary channels voting controller
Decide by vote nucleus equipment of the controller as voting system, play to hold between voting machine and voting master control and open
Under important function.If controller link is decided by vote using cold standby mode, when failure occurs, it is necessary to power off more temporarily
Exchange device, fail-over time is longer, and can influence the carry out process of meeting.If in voting controller link, and adopt
With binary channels concurrent working, each voting subregion has two voting controller cores while supported.Even if any one passage
Voting controller core break down, do not interfere with yet another passage voting controller core normal work, without
Operation is switched over, is realized hot standby in real time, it is ensured that the uninterrupted of conference agenda is smoothed out.
Two sets of completely self-contained control cores are mounted with inside binary channels voting controller, often covering control core has solely
Vertical input power, switch, network interface, radiator fan, 4 tunnels voting trunk cable exits.
The double-core of voting machine does not have the connection on any circuit, it is necessary to which the communication of progress is all to pass through photoelectrical coupler
Part is realized；The double-core circuit board of controller is opened also without the connection on any circuit and intersection using each independent
Powered-down source；Connection between controller and voting machine is also to draw different trunks respectively from two cores of controller respectively
Cable is attached, and for differentiation, we employ two different colors of client cables.
