Definitions
- the invention relates to a configuration management device and equipment maintenance management.
- the field of the invention is that of configuration management and equipment maintenance management.
- the invention relates more precisely to electronic equipment that is integrated into a system.
- This equipment is identified by a configuration that is a reference describing the type to which the equipment belongs, the serial number of the equipment as well as a version of software contained by the equipment.
- the configuration of a device is likely to evolve over time, for example, as a result of an evolution of a software of the equipment.
- Configuration management is the creation of a configuration for a device and updating the configuration to follow the evolution of the equipment.
- maintenance teams are responsible for keeping systems running by relying on messages from equipment-based test devices or observations from system users to build fault diagnoses, identify and / or locate failures, and if necessary, replace a faulty equipment in part or in whole.
- Maintenance management is the collection of messages and observations used to detect equipment failures.
- the invention also relates to an equipment configuration management method and an equipment maintenance management method.
- the architecture of complex systems is generally based on information transfers between electronic equipment interconnected by a communication network.
- the location of equipment in the system sometimes meets the specifications of severe congestion, the equipment can be distant from ten centimeters to several hundred meters and be difficult to access. This is the case of aeronautical systems mounted on board aircraft (for example a avionics suite for broadcasting multimedia contents, referred to as "In- flight Entertainment "or by the acronym IFE) than industrial installations.
- the electronic equipment integrated into a system generally has a configuration that perfectly identifies the main components, software and hardware they contain, from the equipment manufacturer and from the system.
- the configuration takes the form of one or more identifiers that may be affixed to the equipment, such as, for example, markings on a label affixed to the outer surface of a wall of a housing protecting the equipment.
- Equipment configuration allows a maintenance team to replace failed equipment with new equipment with the same configuration or configuration that the equipment manufacturer can ensure that the equipment that carries it is compatible with the equipment. defective equipment.
- the configuration also makes it possible to alert an equipment manufacturer to a chronic failure of one of its equipment. When the manufacturer is informed of all the failures encountered by his equipment in operation, he can make an observation that a frequency of a failure exceeds a certain threshold. Thus, it highlights a weakness of its equipment and propose a common fix for all equipment of the same configuration and which are deemed to suffer from the same weakness.
- An applicable configuration of a system is a list consisting of configurations of the different devices integrated into the system.
- the configuration of the equipment can change over time, it is called system configuration management which is based on an equipment configuration management.
- equipment configuration management could generally be described as "static", ie the applicable configuration of a system was reduced to a system configuration register, for example: for example a document in paper form, which contained all the configurations of the equipment integrated into the system. Any change in a configuration of one of the equipment integrated in the system was logged manually in the configuration register.
- Intelligent configuration management consists of storing the configuration of a device in an internal memory of the equipment.
- the configuration of the equipment is transmitted, during the power supply of the system, before anything else, to a main computer of the system, by means of a communication network connecting, for example star, the main computer and the equipment of the system.
- the main computer verifies that the configurations that the equipment transmits to it are compatible with the applicable configuration of the system which is previously stored in one of its internal memories.
- the "intelligent systems" equipment also includes an integrated test device (known by the English name “Buit-In-Test Equipment” or the acronym BITE).
- the integrated test device delivers messages containing information on the operation of the equipment in which it is integrated through the communication network, to the main computer.
- "Intelligent" maintenance management consists of centralizing in the main computer reports on operating anomalies of the equipment integrated in the system and producing at each shutdown of the system a report summarizing these anomalies that can be usefully consulted by a maintenance team.
- test bench is an installation that is shaped to supply energy and access the contents of the internal memories of the equipment. This installation is expensive and / or bulky and it is not always possible to quickly transport the equipment to a test bench.
- the delay in identifying the configuration of a device can directly affect the downtime of the equipment, and can cause a downtime of a system that can be very expensive.
- RFID Tag or "Radio Frequency Identification Tag”.
- a so-called passive radio tag is a component that has the capacity to store information and to communicate it, on request, to means of a contactless link, usually in the radio frequency range.
- a radio tag in which an equipment configuration information has been stored, is pasted on the equipment, it enables a maintenance team equipped with a radio tag reader / marker to access the equipment.
- Equipment configuration information even when the equipment is not powered, and without the use of a test bench.
- the radio tag is energized by an electromagnetic field which is generally provided by the radio tag reader / marker.
- a radio tag affixed to a device does not allow the equipment configuration to be transmitted quickly to the main computer for final verification of compatibility between the equipment configuration and the applicable system configuration.
- the frequency range of the contactless link for communicating the radio tag is not suitable for communication over a long range, typically more than a few meters, for two main reasons: the power supply decreases very quickly with distance and the environment can attenuate or scramble the radio link, especially if it includes electrical conductive material surfaces.
- a maintenance management based solely on a job of radio tag is not a solution to the problem of communication and storage of messages delivered by the test devices embedded in radio tags, ie in a downward direction.
