In recent years, the market demand for needle and mother row has been maintaining a rapid growth situation. The emergence of new materials and new technologies has also greatly promoted the improvement of the industry application level. At present, the development trend of the needle and mother row market is getting better and better, and realizes its own value in different fields.

In view of the improvement of the miniaturization and intelligence level of the row needle and row mother technology, and the further integration of multiple functions based on information acquisition, which is a certain trend, the multi row needle and row mother data fusion technology also promotes the development of this technology. The local data resources provided by multiple similar or different types of row pins and buses distributed in different locations are integrated, analyzed by computer technology, eliminating possible redundancy and contradiction between information, complementing each other, reducing its uncertainty, obtaining consistent interpretation and description of the tested object, so as to improve the rapidity and correctness of system decision-making, planning and response, and enable the system to obtain more sufficient information. Its information fusion appears at different information levels, including data level fusion, feature level fusion and decision level fusion.

Because it has the following advantages over the single row of pin and bus information, namely, fault tolerance, complementarity, real-time, and economy, it has been gradually popularized and applied. In addition to military applications, it has been applied to automation technology, robots, ocean surveillance, seismic observation, architecture, air traffic control, medical diagnosis, remote sensing technology, etc.
