Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Such as figure 1 As shown, the embodiment of the present invention provides a method for evaluating the health index of expressway mechanical and electrical systems based on AHP and aging index model correction, including the following steps:

[0047] Step 1: Basic concepts of the health index of mechanical and electrical equipment on highways

[0048] The expressway mechanical and electrical equipment health index is a single value between 0 and 10 calculated based on the digital conversion of various information on expressway mechanical and electrical equipment, combined with the operating conditions of on-site mechanical and electrical equipment. The health index is used to represent the health of expressway mechanical and electrical equipment, and different values ​​represent different states of the equipment. 0 means that the electromechan...

Abstract

The invention discloses a health index evaluation method for a highway electromechanical system. The method comprises the following steps of step 1.establishing a basic concept for health indexes of the electromechanical system; step 2.constructing a hierarchical composition structure of the highway electromechanical system; step 3.evalutaing and correcting the health indexes of a single device based on an aging index model; and step 4.carrying out quantitative evaluation on health indexes of all levels of a highway composition structure based on an analytic hierarchy process. Through adoption of the technical scheme of the invention, the devices of the electromechanical system can be effectively managed, and the method has important significance to effective allocation of operation and maintenance funds of the devices.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation system and expressway electromechanical system informatization, and in particular relates to a health index evaluation method of expressway electromechanical system based on analytic hierarchy process and aging index model correction. Background technique [0002] At present, the electromechanical system of expressway has become the support system and realization method of expressway operation management, and is the basic guarantee for the normal operation of expressway. The good working condition of expressway mechanical and electrical equipment plays a decisive role in the high-quality services such as safety, comfort and speed of the expressway. [0003] However, the expressway electromechanical system has complex structure, high technical content and expensive equipment. On the one hand, with the continuous expansion of the expressway network and the continuous increase and...
