    INFRASTRUCTURE INSPECTION AND DIAGNOSIS SYSTEM AND
    ASSOCIATED PROCEDURE
    D E S C R I P C I O N
    OBJECT OF THE INVENTION
    The present invention relates to an infrastructure inspection and diagnostic system and an associated procedure that allows the automatic evaluation of the different variables and devices involved in the operation and control of the infrastructure.
    The object of the invention is an infrastructure inspection and diagnosis system and an associated procedure that allows to know the state of the infrastructure 24 hours a day, 7 days a week, a state that can be known remotely and where a series of data derived from the operation and control to be later evaluated by said inspection and diagnostic system.
    BACKGROUND OF THE INVENTION
    Infrastructure control systems are known in the state of the art, for example power plants, where mechanical energy is converted into electrical energy. Among the above, the main sources of energy are water, gas, uranium, wind and solar energy. These primary energy sources allow moving the blades of a turbine, which in turn is connected to an electric generator.
    The management and diagnosis systems of power plants known in the state of the art allow to carry out the management and diagnosis of the power plant in situ, by means of a series of sensors and status indicators that reflect the status of the different devices and systems of the power plant and allow maintenance of the predictive or corrective power plant.
    However, the previous management and diagnostic systems require the presence of technicians and operators in the power plant itself that carry out these maintenance tasks once the system has carried out the management and diagnosis.
    Management and diagnostic systems are also known that do not allow a global diagnosis of a power plant to be carried out, but simply of each of the subsystems separately.
    5 As the exploitation of energy or work of facilities of this type of infrastructure increases, the requirements for the availability of the facilities also increase, aiming for particularly short downtimes for maintenance and conservation measures. The increasing complexity of the control facilities conditioned by it leads to increasing difficulties in the manipulation by the service personnel 10 in a control maintenance, and in particular both with respect to a broad overview of the current state of the installation and also with regard to early recognition of failures.
    In fact, as the degree of automation increases in a hierarchically constituted gluttony system 15, as is known from EP0242609, a concentration of the increasing pyramid information of the data supplied by the value detection is achieved. measurement; on the other hand, the evaluation of the measurement data is, however, left to the will of the service personnel. In addition, as the complexity of the supervision system increases, its tendency to fail 20 increases.
    Document EP0364151 is known which discloses a diagnostic system with a distributed structure, in which an evaluation of the measurement values is also left to the will of the service personnel.
    25
    The present invention proposes an infrastructure inspection and diagnostic system and an associated procedure that solve all the above inconveniences.

    The infrastructure inspection and diagnosis system subsequently allows, in view of the evaluation of the variables and devices involved in the operation and control of the structure, to decide whether it is necessary to carry out any corrective or predictive action on the infrastructure.

Optionally, the infrastructure inspection and diagnostic system comprises a set of sensors that allow analyzing different infrastructure variables in real time.
    The cameras allow imaging to be carried out so that the control server determines the existence or not of anomalous situations depending on the value of a control analytical performed based on the image obtained by the cameras, in addition to controlling the operation of the cameras themselves and store the images collected by them in the realization of the control analytics.
    The control server also includes a main control module that allows to carry out the control and management of the inspection and diagnostic system of the infrastructure and a control module for the set of cameras that allows the operation of said cameras to be controlled. Optionally the cameras can be fixed, mobile or a combination of both.
    The control server sends an SMS message when a serious infrastructure failure occurs, the warning of which is stored in a database for the generation of reports associated with the corrective actions carried out by a technician.
    The infrastructure inspection and diagnostic system is modular as it facilitates the inclusion of additional control modules, additional sensors and is replicable in another infrastructure without the need to make major changes to its configuration.
