Embodiment Construction
[0089] In order to better understand the purpose, structure and function of the present invention, an event-triggered asynchronous detection method for water system equipment failures of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0090] Based on the positive semi-Markov jump system model, adaptive event triggering strategy, asynchronous detection strategy and filter-based fault detection method, the present invention collects data on the flow rate of water in the water supply pipe, and proposes an urban water system equipment A fault detection method, this method can carry out real-time and effective fault detection on the equipment of urban water control water supply, so as to effectively improve the problem of unstable water supply and water cut-off.
[0091] Such as figure 1 As shown, the water supply system is taken as the research object, the water flow in the water supply network pipe is used as the co...

The invention belongs to the field of automatic control, and discloses an event-triggered asynchronous detection method for an equipment fault of a water affair system, which comprises the following steps of: 1, establishing a state space model of a water affair system; 2, establishing an event triggering condition of the water affair system; 3, establishing a weighted fault model; 4, establishing an event-triggered asynchronous filter model; 5, constructing a fault detection model of the water affair system; 6, introducing a threshold alarm fault detection mechanism; and 7, designing an event-triggered fault detection filter of the water affair system. Based on a positive semi-Markov jump system model, a self-adaptive event triggering strategy, an asynchronous detection strategy and a filtering fault detection method, data acquisition is carried out on the flow velocity of water in a water supply pipe, and a fault detection method for urban water affair system equipment is provided. According to the method, real-time and effective fault detection can be carried out on the urban water affair water supply control equipment, so that the problems of unstable water supply and water break are effectively improved.
Description
technical field [0001] The invention belongs to the field of automatic control, in particular to an event-triggered asynchronous detection method for water system equipment failure. Background technique [0002] With the continuous development of smart cities in recent years, more and more attention has been paid to the supply and management of water resources in each city, and the water system has become an indispensable part of the management of major cities. Water is the material source that people rely on in their daily lives. Today, with the continuous improvement of the quality of life, people's demand for water is increasing day by day. Urban water supply is often unstable, and even water cutoffs occur due to equipment failures and other problems. Therefore, it is necessary to detect the failure of urban water system equipment in time to avoid water supply accidents in which the water supply system cannot work normally due to equipment problems. The water supply syst...
