With the development of the country in information technology, and those technology products are also used in life. Such as capacitive devices in power systems. But capacitive equipment will also have some failures, so it is necessary to monitor it online. Now researchers have found a lot of online monitoring methods, but in most of the current monitoring methods, the monitoring process will produce a huge amount of data, which is very large, so that technicians may miss some important data. In order to solve this problem which can not be discovered early because of the excessive amount of data, this paper adopts some methods based on big data to dig through the data the data obtained by the dig algorithm are statistically analyzed in big data technology.

With the rapid development of China's people's economic growth, people are more and more interested in tourism. With the development of Internet and network multimedia information technology, more and more users share all kinds of tourism information through the Internet. The tour information on the Internet is growing at an exponential rate. How to subdivide customers and recommend appropriate tourism information. This paper mainly analyzes the tourism information resource sharing system of customer segmentation k-means algorithm. Using k-means algorithm to cluster the longitude and latitude of customer tourism images, the images of a certain region can be segmented into images in small regions, Because the images of the same popular landmark are close in space, customer segmentation and sorting are carried out. The experimental results show that the tourism information resource sharing system based on customer segmentation k-means algorithm increases the tourism resource sharing rate by 18%, and analyzes the user's popular surface and representative address through the algorithm. Users will also be interested in the location and heat information of popular landmarks. To obtain the location information of popular landmarks, they only need to calculate the arithmetic mean of the longitude and latitude of the image corresponding to the image clustering of popular landmarks. The result is the longitude and latitude information corresponding to the popular landmark. The tourism information resource sharing system in this paper solves the problem of difficult choice for users. It can quickly obtain effective information from huge data resources and face complex tourism data. Accurate and complete tourism data information is the premise of realizing k-means algorithm + tourism, and obtaining high-quality tourism data resources is very important.

The underwater radiated noise of ships contains a lot of information, which is mainly divided into two signal forms: transient state and steady state. At present, the research technology for steady-state signals has been very mature, but the research on transient signals has always been the focus and difficulty. Therefore, how to obtain the instantaneous characteristics of ship underwater acoustic is an urgent problem in signal acquisition and processing. From the perspective of engineering research, this paper focuses on the analysis of multiple transient signal feature extraction

Aiming at the fault of carbon deposition in spark plug of a certain aircraft engine, the sand blasting cleaning technology was proposed. The sand blasting to remove the carbon deposition in spark plug was carried out and the test results were analyzed. The test results show that the surface color of the spark plug after sandblasting is changed from black gray to bright gray, the resistance value of the central electrode was reduced by 120 and 134Ω, and the central electrode is converted from non-conductive to conductive. At the same time, the roughness of the central electrode and the surrounding metal shell after sandblasting is greater than that before sandblasting, and the surface after sandblasting was coarsened. This technology can remove the carbon in the spark cold surface area, and it can provide a good method for removing the carbon deposition in the engine spark plug.
