Description
Technical field
the invention belongs to research on remote fault diagnosis technology field, particularly relate to a kind of radar remote failure diagnosis system.
Background technology
in recent years, due to develop rapidly and the huge potentiality to be exploited of internet, based on the research of the apparatus remote fault diagnosis technology of Internet, the close attention of domestic and international researcher is received.Utilize various means of communication that fault diagnosis system is combined network consisting, be conducive to managing equipment, reduce equipment investment, improve system availability.
because the complexity of radar equipment improves constantly, the difficulty that diagnosis is safeguarded continues to increase, and device distribution is in wider scope, is difficult to carry out fault diagnosis in time in a lot of situation.For this situation, propose the framework set up based on Internet radar remote failure diagnosis system herein, utilize the advantage of the network information technology, based on existing diagnostic resource and expert system, set up remote diagnosis service centre, realize rapidity and the validity of diagnosis.
Summary of the invention
the present invention is exactly for the problems referred to above, provides the radar remote failure diagnosis system that a kind of diagnosis capability is strong.
to achieve these goals, the present invention adopts following technical scheme, the present invention includes diagnostic center main control computer, expert system module, on-the-spot radar maintenance car, portable tester, its structural feature diagnostic center main control computer is connected with expert system module, on-the-spot radar maintenance car, portable tester respectively.
as a kind of preferred version, expert system module of the present invention comprises database, explanation engine, knowledge acquisition machine, inference machine, knowledge base, database, explanation engine, knowledge acquisition machine are connected with diagnostic center main control computer respectively, knowledge base is connected with explanation engine, knowledge acquisition machine, inference machine respectively, and inference machine is connected with database.
as another kind of preferred version, on-the-spot radar maintenance car of the present invention comprises measured piece, test board, programmable instrument, and test board is connected with measured piece, programmable instrument respectively.
beneficial effect of the present invention.
the characteristics such as the structure opening that the present invention utilizes Internet to have, information sharing, remote failure diagnosis system overcomes the obstacle that General System is difficult to overcome, and has higher cost performance and stronger diagnosis capability.
Accompanying drawing explanation
in order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
fig. 1 is schematic block circuit diagram of the present invention.
Embodiment
as shown in the figure, the present invention includes diagnostic center main control computer, expert system module, on-the-spot radar maintenance car, portable tester, diagnostic center main control computer is connected with expert system module, on-the-spot radar maintenance car, portable tester respectively.
described expert system module comprises database, explanation engine, knowledge acquisition machine, inference machine, knowledge base, database, explanation engine, knowledge acquisition machine are connected with diagnostic center main control computer respectively, knowledge base is connected with explanation engine, knowledge acquisition machine, inference machine respectively, and inference machine is connected with database.
described on-the-spot radar maintenance car comprises measured piece, test board, programmable instrument, and test board is connected with measured piece, programmable instrument respectively.
core of the present invention is remote diagnostic center, diagnostic service center mainly provides coordination and the management work of diagnostic task, center is after the diagnosis request of receiving strange land equipment, discriminator carried out to diagnosis request and starts diagnostic expert system, selecting suitable Diagnostic Strategy to start fault diagnosis reasoning.Fault diagnosis software based on expert system is just arranged on wherein.
when serious fault appears in equipment, device context maintainer can not make correct process, and local system is by request remote diagnosis service.After local and remote diagnosis system connect, remote diagnostic center system is interacted by man-machine interface and diagnostician, diagnostician can obtain real-time information or the historical information of local device as required, by breakdown judge being fed back to local system after analysis ratiocination.Maintenance personal by the suspected fault UUT dismounting on radar according to Remote Expert System prompting, takes and tests to on-the-spot radar maintenance car test board, and return to diagnostic center result by network.Expert accesses diagnostic center by Internet, modification and perfection expert system, and user accesses diagnostic center by the on-the-spot radar fault in expert system prompting diagnosis location, finally therefrom gains in depth of comprehension to diagnostic result.
in conjunction with the feature of radar, utilize the Theories and methods of artificial intelligence, by the knowledge and experience in addition systematization of experienced expert about fault diagnosis, form the knowledge base of fault diagnosis expert system, continuous accumulation is about the knowledge of fault diagnosis, realize knowledge sharing, be conducive to location and the diagnosis of fault.
native system test board part is the Auto-Test System based on LAN bus, is made up of simulation test bench and hybrid test platform.Analog circuit test platform is mainly used in testing the module based on mimic channel in radar, takes into account the intelligent instruments such as digital multimeter form primarily of oscillograph, frequency spectrograph, power.Hybrid circuit test board is made up of digital module, D/A module, scanning switch module, switch module, DMM module, adapter, test bus interface card, power supply, oscillograph etc.Test board is connected with computing machine by GPIB, RS232C, USB, Ethernet interface etc., and composition test macro, supports VISA software standard.The part of data acquisition of native system is a Portable data acquisition instrument, can gather the radar system performance index needed in fault diagnosis, and preserves data with text form.
above content is the further description done the present invention in conjunction with concrete preferred implementation; can not assert that specific embodiment of the invention is confined to these explanations; for general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; some simple deduction or replace can also be made, all should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
