A remote maintenance system 100 in which a center server 120 that is located in a service center for performing maintenance of an electrical appliance 102 and a home server 101 that is located in each house and monitors a status of the electrical appliance 102 in the house are connected via a communication network 140, wherein (A) the home server 101 includes an electrical appliance management unit 108 that acquires a status value of the electrical appliance 102, a communication unit 105 that receives from the center server 120 a failure model which is information defining a method of deriving a decision whether the electrical appliance 102 is failed or not from the status value, and a failure deciding unit 106 that decides whether the electrical appliance is failed or not based on the acquired status value and the received failure model using qualitative reasoning, and (B) the center server 120 includes a failure model updating unit 127 that updates a failure model and send the updated failure model to the home server 101 via a communication unit 125.

The invention provides a system and method for remotely diagnosing and repairing a plurality of Automatic Data Collection (“ADC”) device platforms. A remote service technician utilizes a computing system having browsing software that communicates with a network of ADC platform devices. Diagnostic queries for particular ADC devices may be retrieved by the browsing software from a diagnostic server that sends Hypertext Mark-Up Language (“HTML”) documents, Dynamic Hypertext Mark-Up Language (“DHTML”) documents, and / or Extensible Mark-Up Language (“XML”) documents containing appropriate diagnostic applets. The remote technician sends diagnostic queries to a Simple Network Management Protocol (“SNMP”) master agent at the ADC device platform, and a translator translates the diagnostic queries sent to the ADC device platform into a format suitable for reception by its ADC devices in order to effect anomaly diagnosis and functionality restoration. Another translator translates data received from the ADC device into the SNMP format for transmission to the remote service technician in order for the remote service technician to perform diagnostic analysis. The SNMP master agent communicates with the remote computing system using the Transmission Control Protocol (“TCP”), the User Datagram Protocol / Internet Protocol (“UDP / IP”), and / or the User Datagram Plus Protocol (“UDP+”). The ADC platform device may also utilize a wireless communication system for communicating with the remote service technician.

Systems and methods of the present disclosure are directed to providing centralized diagnostic services to a plurality of heterogeneous computing environments deployed at different data centers on different networks. In some embodiments, a centralized diagnostic tool establishes a connection to a server of a data center that deploys a computing environment with components. The centralized diagnostic tool validates automatically a component of the computing environment based on a corresponding configuration file received from the server for the component. The centralized diagnostic tool establishes a virtual device simulating a client application executing on a client device. The client application can be configured to communicate with the component. The centralized diagnostic tool automatically initiates a request using a predetermined protocol flow, and the virtual device transmits the request to the component. The virtual device receives a response to the request indicative of a status of the computing environment.

A remote maintenance system has a center server that is located in a service center for performing maintenance of an electrical appliance and a home server that is located in a house and monitors a status of the electrical appliance 102 in the house which are connected via a communication network. The home server includes an electrical appliance management unit that acquires a status value of the electrical appliance, a communication unit that receives from the center server a failure model which is information defining a method of deriving a decision whether the electrical appliance has failed or not from the status value, and a failure deciding unit that decides whether the electrical appliance has failed or not based on the acquired status value and the received failure model using qualitative reasoning. The center server includes a failure model updating unit that updates a failure model and sends the updated failure model to the home server via a communication unit.

Embodiments of the invention provide a method for determining errors and metrics in a computer network. The method includes positioning an analyzer in communication with the network, capturing a data trace of the network with the analyzer, determining a network device topology from a first processing of the data trace, building user layer protocols using a second processing of the data trace and the determined device topology, determining errors in the network device topology using protocol experts applied to the user layer protocols in conjunction with the determined device topology, and displaying at least one of the device topology and the determined errors to a user.

A computer-implemented system and method for generating a hardware implementation of graphical code. The method may operate to configure an instrument to perform measurement functions, wherein the instrument includes a programmable hardware element. The method comprises first creating a graphical program, wherein the graphical program may implement a measurement function. A portion of the graphical program may be converted into a hardware implementation on a programmable hardware element, and a portion may optionally be compiled into machine code for execution by a CPU. The programmable hardware element is thus configured utilizing a hardware description and implements a hardware implementation of at least a portion of the graphical program.

A system and method for diagnosing an electronic device remotely using a network is provided. The electronic device includes one or more programmable logic devices that are configurable. A diagnostic microcontroller functions to communicate to the programmable logic devices and to communicate to the network. To diagnose the electronic device, communication is established to the network and to a diagnostic / repair center. The diagnostic / repair center selects diagnostic commands and transmits them to the electronic device. The diagnostic microcontroller initiates the diagnostic commands on the one or more programmable logic devices to test their configuration and / or functionality. Test results are collected and transmitted back to the diagnostic / repair center for analysis. Based on the analysis, if appropriate, reconfiguration commands are sent to reconfigure the programmable logic device to correct identified errors.
