Status display.
In some embodiments of the present invention, the hardware configuration of shown RIOM cabinet as shown in figure 5, include power module 17,
Gateway module 18, DI module 19, DO module and AX module, concrete configuration are as shown in table 2.
Table 2
In a system, it is contemplated that whether the number of actual controlled equipment the number of specific control function, has RIOM superfluous
Complementary work can etc. many factors, configure 2 to 4 RIOM cabinets to realize the control function of requirement, wherein DI module, DO module,
AX module can increase and decrease quantity according to the actual situation.
Entire microcomputer network system can according to need and configure network system based on MVB communication mode, based on Ethernet
The compatible double net systems of the network system of communication mode or two kinds of communication modes, wherein for RIOM related data use with
The processing method of display also different from.
Assuming that have CCU module, RIOM module, DDU module in network system, these three equipment have Ethernet interface and
MVB interface, can receive Ethernet data and MVB data from network, and controlled plant is connect with RIOM module by rigid line.
In MVB network topology structure as shown in FIG. 6, CCU module, RIOM module, DDU module are connect by respective MVB
Mouth sends data in MVB bus, and whether just DDU module receives the RIOM module from the sending of CCU module from MVB bus

Total judgement signal, " 0 " " 1 " shape of the self-test signal in each channel, each channel that are issued in conjunction with RIOM module corresponding ports
State signal shows to carry out related pages.
Specifically, if CCU judges that some RIOM module does not work and issues signal to DDU, DDU module is just not
It must judge the status information that RIOM module issues, directly display RIOM module off position.Similar, if CCU judges
Some RIOM module works normally, and its a certain board does not work, then DDU just sentencing without a certain board inner passage
Disconnected display, directly displays this board off position.If CCU judges that RIOM module and each board are normal conditions,
So DDU is then shown in conjunction with the specific channel status that RIOM module issues.
In ethernet network topological structure as shown in Figure 7, CCU module, RIOM module, DDU module by it is respective with
Too network interface sends data on industry ethernet, and each equipment sends and receives data by multicast mode.The RIOM of DDU module
Module data is shown, same as the previously described embodiments.
Double net topology structures as shown in Figure 8, DDU module had not only had received the RIOM data from MVB bus but also had received
The RIOM data from industry ethernet have been arrived, how two kinds of data are accepted or rejected, it is divided into following three kinds of situations:
I.CCU and two kinds of networks all establish normal communication
In such cases, DDU receives the Ethernet of RIOM module and MVB data are effective.So DDU is shown
RIOM related data is then a circuit-switched data of corresponding CCU selection processing, and CCU sends RIOM to DDU by other port at this time
Selection data bit, if selection is ethernet channel, DDU the RIOM related data received from Ethernet interface into
Row processing and display, if instead selection MVB data, then handle the RIOM related data received from MVB interface and shown
Show.The variable at the interface RIOM is all selected by CCU or to send.
Ii.CCU only establishes normal communication with MVB network
At this point, leading to even if DDU has received the data of RIOM module from Ethernet interface since CCU currently only trusts MVB
Letter mode, then the related interface RIOM of DDU also only shows the related MVB data of RIOM.
Iii.CCU only establishes normal communication with Ethernet
At this point, the interface DDU correlation RIOM only shows Ethernet data with the processing mode of ii.
As shown in figure 9, the selection and processing of network datas bis- for RIOM.Big box 20 is the choosing of the device name to be checked
Key is selected, this interface includes RIOM1 to RIOM4 module.Box 21 is that selected equipment shows the data class for using communication mode
Type, selecting which kind of communication mode is that CCU is sent to display screen.CCU can only select a kind of communication mode in synchronization, if
Selection is MVB data, then " MVB data " icon on the left side, and background color is deepened, otherwise selection is Ethernet data, then
" ETH data " background color on the right is deepened.Box 22 is the related MVB port data content of corresponding RIOM1, can be seen at this time
It arrives, it is 0x110, three ports of 0x111,0x112 that corresponding three ports RIOM1, which are respectively port address,.Each port has 32
The valid data of a Byte length.Box 23 is the relevant Ethernet data content of corresponding RIOM1, right for convenience at this time
It answers, the related data of RIOM1 Ethernet is split into corresponding MVB data format.Box 24 is the interface navigation explanation of DDU.
From big box 20 select the RIOM equipment to be checked after, box 21, box 22, box 23 information according to selected by
Equipment variations.Initial data used by state and redundancy the comparison interface of all correlation RIOM of DDU is according to equipment (CCU mould
The communication mode of block confirmation) select data packet.Box 22 and box 23 are the data of two kinds of communication modes, are used on one side,
It is abandoned on one side.
