Structured system for monitoring and controlling the engineering equipment of an installation

The present inventions pertains to the field of automatic control systems based on computer technology, and essentially relates to a structured system for monitoring and controlling the engineering equipment in an installation, mainly a building comprising several floors. The system includes a central computer module with an input-output device as well as a plurality of monitoring and/or measuring and/or control sensors and/or control devices for the units and apparatus of the engineering equipment in the building. The module consists of a programmable computer server station having functions, according to the software, that provide for the centralized reception of monitoring data through information channels within a single network protocol, as well as for the processing of said data and for the output of control signals towards the control devices for the units and apparatus of the engineering equipment in the building. This system further includes controllers connected in a “star” circuit to the input-output device of the central computer module. Each controller has a plurality of remote input-output modules connected serially thereto, while each of said modules has a corresponding sensor or a control device connected thereto. At least one additional computer station is connected through its input-output module to the corresponding controller that ensures, according to the software, the local monitoring and the control of the units and apparatus in at least one functionally independent section of the engineering equipment in the building.

The invention discloses an accelerated test method of an LED (light-emitting diode) lighting lamp based on subsystem decomposition. The method comprises the steps that: firstly, an LED lamp system is decomposed into a plurality of functionally independent subsystems; next, under precondition that the whole system is maintained to be able to work in a closed state, a target subsystem is placed in an accelerated test environment and is subjected to accelerated reliability test; by utilizing data measurement result obtained in the accelerated test progress, a reliability function of the target subsystem is obtained through extrapolation; and finally, the relevance in performance change of each subsystem and performance change of the whole lamp system is combined, the reliability function of each subsystem is synthesized through application of a system reliability statistical analysis method, then, the reliability function of the whole LED lamp system is obtained through derivation, and reliability evaluation of the whole lamp system is realized. According to the method disclosed by the invention, the complexity, even the infeasibility of an accelerated reliability test directly aiming at the whole lamp system can be avoided; the method not only can be applied to evaluation of accelerated reliability test of the LED lighting lamp, but also can be used as reference for evaluation of the accelerated test of other complicated systems.
