Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
the invention discloses an intelligent online monitoring system for a ring main unit, which is mainly used for online acquisition of safety data of the ring main unit, and real-time monitoring and recording of the conventional inflatable ring main unit.
The intelligent management platform uses a mobile terminal APP technology, and displays the state parameters of the ring main unit in a more visual mode through acquiring real-time data transmitted by the background, so that the intelligent management platform is more beneficial to people to check. The alarm device module is located inside the ring main unit body and used for finding abnormal parameters and giving an alarm, and when a partial discharge signal is detected, the alarm device module can be triggered to give an alarm. The detection sending unit comprises a main controller, an ultrahigh frequency sensor module, a vibration sensor module, a sound sensor module and a first wireless communication module.
Referring to fig. 1, a system block diagram of an intelligent online monitoring system for a ring main unit is shown, in which the overall architecture of the system is summarized from three dimensions of a presentation layer, an application layer, and a service layer. The software development of the system adopts a working mode of front-end and back-end separated development, and the development of the front-end and the back-end are carried out simultaneously, so that the working efficiency is improved. The page can be easily loaded according to the needs by the configuration of the front-end route, the server does not analyze the front-end page, the page interaction and the user experience are optimized, and the maintainability of the code is enhanced. Through a centralized storage management mode of vuex, front-end page components can be managed in a unified mode, and a response type sharing characteristic is achieved. The data interaction utilizes a restful style interface and an axios technology, the back end only needs to provide an interface and process data, and the page only needs to send a request and json data, so that stable and efficient data interaction can be easily realized. Through real-time parameters, indexes such as temperature and humidity and ozone of the ring main unit are monitored in real time, and meanwhile, equipment state information of the current time can be checked. The real-time parameter acquisition can intuitively know the fluctuation of the parameters in one day, and is favorable for the overall judgment of professional personnel in the management ring main unit.
The running state of the ring main unit is detected through the sensor, real-time data are provided for the background system to be visually displayed, the function of remotely detecting the ring main unit is achieved, the background system can perform early warning according to the change of the equipment state of the ring main unit, and the result of state evaluation is automatically produced, so that the management pressure of professionals is reduced, and the daily running requirement of the equipment is improved. When the wireless sensor detects that the equipment state index exceeds the standard, the early warning state is started immediately, data is sent to the background to give an alarm, the background receives an alarm signal immediately, and the current equipment state is transmitted to professionals.
Fig. 2 is a functional flow chart of the intelligent online monitoring system of the ring main unit.
According to the online looped network cabinet intelligent detection platform, the current looped network cabinet management mainly depends on manpower, the specific state, parameters and the like of the looped network cabinet cannot be directly and remotely checked, and whether the looped network cabinet has an abnormal condition at present cannot be checked. The system can acquire parameters in the ring main unit such as temperature, humidity and ozone in real time, and professionals can further perform routing inspection judgment through the real-time data. When the looped netowrk cabinet appears abnormal parameter, this platform also can report an emergency and ask for help or increased vigilance in real time, and the notice user has appeared which abnormal time this moment, can carry out twenty-four hours real-time detection to all looped netowrk cabinets in the transformer substation. The main platform of realizing is the mobile terminal of the mobile phone, the user who faces is the professional related to the management of the ring main unit, and the user can inquire the real-time state parameters of the ring main unit after selecting the ring main unit in the area. In order to ensure the normal operation of a power supply system, the problem that an intelligent ring main unit is low in fault detection model and poor in generalization performance needs to be solved by nonlinear transformation. The PCA algorithm is a common fault judgment method based on statistics, new main characteristics including training set data and mutually orthogonal low-dimensional spaces are obtained through the change of a coordinate system of the training set data, and the complex process of linear analysis of the original process is simplified. However, this method ignores higher order relationships between parameters, so it is often not desirable for data that if non-linear relationships exist. Therefore, based on the problem, the system introduces a KPCA algorithm which maps the original space to a high-dimensional feature space through a kernel function, and replaces the inner product operation of the high-dimensional feature space with the kernel function operation, thereby simplifying the calculation process. In the aspect of hardware, the on-line monitoring system acquires state information in the inflatable cabinet through the environment sensor acquisition layer, the state information comprises key index parameters such as air pressure, moisture content and running load current, and meanwhile, when the key parameters are abnormal, the system can also send an alarm to professional power personnel, the information can be uploaded through the network communication layer, and the centralized monitoring center completes information acquisition fusion and fault diagnosis and analysis. And the visualization of data and the real-time fault alarm are realized by utilizing a high-performance database management center of the monitoring center and a friendly online interaction interface.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
