A kind of internet communicating monitoring equipment main control computerTechnical field
The present invention relates to field of network communication, in particular to a kind of internet communicating monitoring equipment main control computer.
Background technique
Internet communicating monitoring computer mainly completes the reliable control to remote equipment, and equipment has a setting analysis, calculatesAnd the function of human-computer interaction.It is required that monitoring computer can continue permanent continuous work, when monitoring host computer encounters failure,Start backup machine immediately, continues to monitor.In external dump, monitoring computer works on by itself built-in power.Railway systems are mainly concerned with the personal safety of a large amount of personnel, it is desirable that any order of control computer output is all accurate's；The outer space, unattended and maintenance are chronically in terms of onboard system, it is desirable that monitoring device main control computer continuous work for a long timeThe reliability of work.
In relation to monitor computer related patents Chinese patent literature (number of patent application 201610578084.6,201110327367.0) in have disclosure.But it is calculated in these controls for not relating to internet communicating monitoring in the prior artMachine, thus how planned network communication monitoring equipment main control computer, then be problem to be solved in the prior art.
Summary of the invention
The technical problems to be solved by the invention are to provide a kind of internet communicating monitoring equipment main control computer, solve existingNetwork communication monitoring device poor reliability in technology is difficult to the problem of continuing monitoring after failure.
Concrete scheme of the invention is as follows:
A kind of internet communicating monitoring equipment main control computer, comprising: arbitration plate, mainboard A, mainboard B, power supply A, power supply B, backboard,Human-computer interaction, rechargeable battery set and casing；
Arbitration plate, mainboard A, mainboard B, power supply A, power supply B, backboard, human-computer interaction, rechargeable battery set are respectively mounted and are fixed on the machineOn shell；
Arbitration plate, mainboard A, mainboard B, power supply A, power supply B, human-computer interaction, rechargeable battery set are connect with backboard.
Above-mentioned computer, it is preferred that mainboard A, mainboard B are the mainboards of duplicate configuration；
Power supply A, the duplicate configuration of power supply B power panel；
Arbitration plate selects one as host by backboard from mainboard A, mainboard B, another is as standby host；
Arbitration plate selects one as main power source by backboard from power supply A, power supply B, another is as backup power source.
Above-mentioned computer, it is preferred that power supply A, power supply B directly connect AC220V alternating current, and give arbitration plate, master by backboardPlate A, mainboard B, human-computer interaction, rechargeable battery set power supply.
Above-mentioned computer, it is preferred that in AC220V mains-supplied, when rechargeable battery set electricity is less than, power supplyA, power supply B is charged by backboard to rechargeable battery set；
In AC220V mains-supplied, when rechargeable battery set electricity is full of, power supply A, power supply B do not fill rechargeable battery setElectricity；
When not connecing AC220V mains-supplied, rechargeable battery set gives arbitration plate, mainboard A, mainboard B, man-machine friendship by backboardMutually power supply.
Compared with the prior art, the present invention has the following advantages: continuous working period is long, and there is fault detection, failure to detectThe characteristics of survey, failure selfreparing, standby host start automatically.
Detailed description of the invention
Fig. 1 is a kind of structural block diagram of internet communicating monitoring equipment main control computer of the present invention.
Specific embodiment
Specific embodiment is described in detail below in conjunction with attached drawing.
Structural block diagram of the invention is as shown in Figure 1, a kind of internet communicating monitoring equipment main control computer, comprising: arbitration plate1, mainboard A 2, mainboard B 3, power supply A 4, power supply B 5, backboard 6, human-computer interaction 7, rechargeable battery set 8 and casing 9；Arbitrate plate1, mainboard B 3, power supply A 4, power supply B 5, backboard 6, human-computer interaction 7, rechargeable battery set 8, which are respectively mounted, is fixed on the casing 9On；Plate 1, mainboard A 2, mainboard B 3, power supply A 4, power supply B 5, human-computer interaction 7, rechargeable battery set 8 is arbitrated to connect with backboard 6It connects.
System is designed as standby machine mode, and mainboard A 2, mainboard B 3 are the mainboard of duplicate configuration, power supply A 4, electricityThe power panel of the duplicate configuration of source B 5, active and standby selection use competition mechanism.Start when system is powered on, arbitrated logic is first write from memoryRecognizing mainboard A 2 is host, and total interface signal (USB, VGA, LVDS, I/O etc.) is connected to mainboard A 2, is hereafter arbitrated in plate 1Arbitrated logic waits the starting of (60s) system, and ruling mainboard A 2 is host after 60s.In the process, if event occurs for mainboard A 2Barrier, at this time if mainboard B 3 is working properly, ruling mainboard B 3 switchs to host, and failure machine enters minor failure state, ifFailure machine fails to restore normal, then issues police instruction to failure machine.
As a same reason, arbitration plate 1 startup stage from power supply A 4, power supply B 5 select one as main power source, anotherAs backup power source.AC220V alternating current is powered directly to power supply A 4, power supply B 5, and power supply A 4, power supply B 5 are by backboard 6 to secondaryCut out plate 1, mainboard A 2, mainboard B 3, power supply A 4, power supply B 5, human-computer interaction 7, the power supply of rechargeable battery set 8.In AC220V alternating currentUnder electric power thus supplied, when 8 electricity of rechargeable battery set is less than, rechargeable battery set 8 is charged by power supply A 4, power supply B 5；Rechargeable batteryWhen 8 electricity of group are full of, 8 starting protection function of rechargeable battery set stops charging.
When the systems are operating normally, host and main power source work normally, and constantly receive and dispatch fault detection signal；Standby host and standbyIn a dormant state with power supply, it can wake up at any time.When host receives fault-signal, standby host and backup power source are waken up immediately,And failure fault detection signal is issued, startup separator selfreparing continues.When external power supply AC220V interruption or failure, charging electricityPond group 8 is powered to backboard 6 to arbitration plate 1, mainboard A 2, mainboard B 3, human-computer interaction 7 automatically, so that safeguards system works normally.
