Volleyball events occupy an important and unshakable position in the hearts of Chinese people,and it is the glory of Chinese competitive sports.Putting scientific and technological analysis methods and methods in the research of volleyball events is the trend of modern competitive sports development,and it is also one of the strong guarantee ways to promote the improvement of the competitive level of various countries.The unique advantage of BP neural network algorithm is to construct the team's collective technical and tactical ability structure model.The non-linear quantitative mathematical relationship describes the relationship between technical and tactical ability structure and winning and losing results.Training and improvement;input of the team's technical and tactical performance in different seasons of matches,verifying the accuracy of the model's prediction of the team's victory and defeat results.In the face of the ever-changing match situation,the coach passed the accurate and effective technical and tactical strategies to the players on the field in a timely manner.After the match,the opponent's advantages and disadvantages were clarified.This article is based on the 2018-2019 season Chinese Women Volleyball Super League as the model basis,and the 2019-2020 new season league is used as a simulation prediction.This study is conducted with the goal of winning the game to help the team make up for shortcomings and improve the efficiency of daily training.,Reasonable lineup deployment,complementary lengths between players,and hope to play a role in delivering more fresh "blood" to the national women volleyball team.(1)With the help of the model's non-linear quantitative mathematical expressionneural network analysis,to explore the relationship between the technical and tactical capabilities of the four teams and the outcome of the game,whether the results obtained are relative to the top four of the 2018-2019 season as a whole or relative As for the teams,they all accord with the actual technical and tactical performance to a high degree.The constructed neural network model is effective for analyzing the collective technical and tactical capability structure of the Chinese Super Women Volleyball League team.(2)The simulation tests on the models of the Beijing Women' Volleyball Team and the Jiangsu Women Volleyball Team that have been constructed as examples show that the deviations between the prediction results of the two teams' models and the actual results show small differences,and the prediction accuracy of the network is better.The model constructed based on the BP neural network method is used to predict the season results of the Chinese Women Volleyball League team,which is of practical significance.(3)The technical and tactical capabilities of each team are characterized by:(1)The champion team 's Beijing women 's volleyball team has the largest direct scoring rate,has a strong initiative scoring ability,and the turnover rate of various indicators is relatively low;The in-place rate accounted for the largest proportion,the ability to smash offensive scoring,played instability in this season;(3)Shanghai women volleyball team won the third place in this league,defensive ability is the team's winning advantage at the same time,it is also inadequate.The higher turnover rate of the index has a greater impact on the team's competition performance;(4)The passing rate of the women volleyball team in Jiangsu accounted for the largest proportion,and the overall efficiency of the offensive smash attack was low,limiting the team's play in this season.(5)The direct scoring abilities of both the starting and deducting stages are also outstanding in the technical and tactical capabilities of the Beijing Women Volleyball Team and Jiangsu Women Volleyball Team.Through the transfer of players,the Beijing Women Volleyball Team,which makes up for the shortage of the team,has a balanced performance in technical and tactical capabilities,and its capabilities have stabilized.The first pass defense ability is one of the biggest shortcomings of the Jiangsu Women Volleyball Team.However,the stability of the team members' own active scoring ability is not high;the Shanghai women volleyball team's technical and tactical ability structure output performance during the entire season is significantly less than the other three teams,which has a greater impact on the team's victory and defeat results.
