Before the start of the game, the referee is responsible for collecting and filling in the scoring book from the referee (or the head of the referee group) to check whether the height of the net, the placement of the net columns are correct and whether the net is damaged; Whether the position of linesman and serve referee is appropriate; Assemble athletes, choose sides, serve first, on the court; Lead athletes into the competition venues; Choose a game ball.
The game starts from the referee's "0: 0", and the referee wants to score points; Score (players score first, singles-when one side loses the right to serve, report "changing serve" first and then score. Doubles-when the server loses the right to serve for the first time, he will report the "second serve" first and then score); It also depends on whether the ball that falls near the sideline and is not noticed by the linesman is in bounds;
Judging the illegal behavior of the receiver when serving and the illegal behavior of both sides in the game; Pay attention to avoid unnecessary delay in competition time, and have the responsibility to warn athletes that if they continue to delay, they will be sentenced to violation; Correctly implement the choice of "rematch"; If foreign badminton or other people or things invade the competition area and affect the competition, they should be sentenced to "re-serve"; When the game is interrupted unexpectedly, the score at that time should be recorded in the score book, and what is the position of the server and the receiver in doubles and doubles; Correctly implement and remind athletes to change venues.
Badminton serve referee rules focus on the action of the server when serving, and have the final referee power. Usually sitting in a low chair opposite the referee, he is responsible for paying attention to whether the server has stepped on the line with his foot when serving. Whether the hitting moment is "over the waist", "over the hand" or "not hitting the ball first"; There is no misconduct in serving with a badminton racket. If there is any violation, you should immediately announce "violation" loudly and ensure that the referee can hear it.
Badminton linesman rules have the final decision on whether the facts on the supervised line are in or out of bounds. For example, if the ball falls out of bounds, no matter how far it is, it will be gestured (arms raised horizontally); If the ball falls within the boundary, point to the landing point on the boundary with the index finger of the right hand; If the line of sight is blocked, you should immediately raise your hand and cross in front of your eyes, and the referee will make a ruling. If the referee doesn't see it, you should re-judge the service, not according to the opinions of the players or the off-site personnel. All gestures should be made sure that the referee can see clearly.
