Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, hyperchannel ARINC700 monitoring bus device consists of industrial computer 1, bus adapter 2 and bus access device 3.
Comprise private communication board 12 in industrial computer 1, private communication board 12 is by multichannel ARINC429 module composition;
Bus adapter 2 is by mainboard, selftest module, power management module and switch matrix module composition.
Industrial computer 1, for moving the monitoring bus procedure set, with bus adapter 2, be connected, it is by calling inner hardware resource and software resource, bus adapter 2 is sent to adaptive instruction, call bus adapter 2 internal resources, system needs the access of data monitoring circuit on the bus of test, complete the collection of data, then the bus data and the ICD data-base content that collect are compared to rear demonstration or directly storage; The ICD database is exactly the database according to the ICD file set up of different type of machines, and this document has defined the implication of every ARINC429 bus representative, solution be this bus is come wherefrom, the problem gone there.
Bus adapter 2 is connected with industrial computer 1 interface, and is connected with bus access device 3, by bus adapter 2, makes the control data and the bus data that transmit in system realize exchange between industrial computer 1 and bus access device 3.
Bus access device 3,256 tunnel aviation buses are connected with bus adapter 2, for the data monitoring circuit being articulated in to the aviation bus that needs test, bus access device 3 inside comprise aviation bus wiring frame and ZIF(zero insertion force) joint 31, distributing frame is connected all aviation buses with ZIF joint 31 p-wires, while on bus, data transmission being arranged, the data indicating module in supervisory circuit can send light flash.
Bus adapter 2 comprises: mainboard for the master control adapter 21, selftest module for the adapter self check 22, one for giving the power management module 23 of the inner modules power supply of adapter; A switch matrix module 24 for the bus run switching, in order to distinguish different monitoring ranks, cost-saving, switch matrix module 24 is divided into A, B, tri-kinds of models of C.
Wherein A type rank is the highest, is Full Featured 16 * 256 way switch, can monitor 256 tunnel buses fully, and each supervisory circuit can be articulated to arbitrarily on 256 tunnel aviation buses.
8 * 128 way switch that Type B is half function, can complete the monitoring of 128 tunnel aviation buses, the other monitoring that just can complete all 256 tunnel buses of cascade, but each piece switch matrix board can only be monitored above 128 tunnels that are connected to this board, can not monitor an other board of cascade.
1 * 16 way switch that the C type is basic type, the using method of function and Type B is similar.Above the board of three models can meet different monitoring demands, the user can configure according to the test assignment of oneself different switch matrix boards.
Be illustrated in figure 2 hyperchannel ARINC700 monitoring bus implementation method software function module division figure provided by the invention.When the user need to carry out monitoring bus to the ARINC700 serial component of access aviation bus, at first aviation bus access device is connected with bus to be measured, the bus adapter two ends link together bus access device and industrial computer, power on to whole system, then open industrial computer operation bus data watchdog routine collection.
At first, system enters self-check program, main inspection hyperchannel ARINC700 monitoring bus device provided by the invention whether can use by telotism, whether there is fault in itself, mainly comprise ring certainly and the outer ring test of private communication board, modules functional test in bus adapter, distributing frame wire harness connecting test in the bus access device.Only in the situation that self check by just entering following flow process.
After self check is passed through, software resource and the hardware resource of the bus data watchdog routine configuration-system of system, and complete the required initial work of data monitoring.The initial work here mainly completes special-purpose logical
letterthe configuration of the passage of board, transfer rate, supervision interval step is set etc.
After passing to bus adaption equipment under steering order, command word is resolved, gauge tap matrix board, be mounted to the test circuit of private communication board on the bus that will test, and the calling data acquisition module, just can complete the monitoring of bus data.
The bus data collected is transferred to respectively display module and memory module is processed, and the ICD database that wherein display module contrasts corresponding type by data is resolved, and completes ARINC700 module data word to the real time parsing of actual physics meaning and shows.Memory module directly deposits data in supporting database, offline playback and ex-post analysis after finishing in order to monitoring.
The method for building up of ICD database: due to the airline carriers of passengers of different model, its for the ICD file all different, in order to make the bus data of the present invention's parsing as much as possible ARINC700 serial component, by the isolation of the exclusive data communication card of ICD database and bottom, develop several relatively independent ICD databases, the data of transmitting in serial component are stored in database, packet is containing data physical significance, transfer rate, steering logic, the code parsing form, the main contents such as sign bit.After bus data reads, directly corresponding with the ICD database, industrial computer is searched relevant information automatically, has reduced the event expense, can complete the timely processing of data.When needs are monitored different bus apparatus, only need to import to want the ICD database of answering, just can complete the switching of monitoring.
As shown in Figure 3, the hyperchannel ARINC700 monitoring bus implementation method of utilizing the invention described above to provide comprises the following step carried out in order:
(1) equipment self-inspection: industrial computer is connected with bus adapter, the bus access device is connected with bus adapter, then the system power-on self-test;
(2) whether the judgment device self check is passed through;
(3) device initialize: configure hardware resource and software resource;
(4) monitored instruction loads: at first judge whether to need to change the channel number of monitoring, then bus adapter is mounted to corresponding bus run according to the instruction of industrial computer by the monitoring bus circuit;
(5) bus data acquisition: while on bus, data transmission being arranged, the private communication board just can read out data;
(6) data the processing stage: the bus data that the private communication board reads is done the processing of two aspects:
A,
willbus data translates to actual physical meaning;
B, data directly store supporting database into, for monitoring the Treatment Analysis after end;
(7) demonstration of bus data: contrast the ICD database of corresponding type, the physical significance that collects data is shown in real time;
(8) the analysis playback of storage data: the data file offline playback of calling storage;
(9) judge whether to need to revise monitor channel; While needing to revise, send new load instructions;
(10) monitoring finishes.
