wherein each pair of correlation sensors comprises one transmitter and one receiver.
It should be noted that each pair of correlation sensors includes a transmitter and a receiver, and visible light or invisible light is sent to the receiver through the transmitter, and if an obstacle blocks the light, the receiver cannot receive the light, which indicates that the obstacle exists. Each pair of opposite-emitting sensors can be arranged on two sides of the snowplow, namely, the emitter of the opposite-emitting sensor is arranged on one side, and the receiver of the opposite-emitting sensor is arranged on the other side. And a plurality of sensors may be provided on each side, for example 5-15 transmitters and 5-15 receivers on the corresponding other side. The emitter and the receiver in each pair of correlation sensors can also adjust the spacing, and the spacing of each emitter can be set to be the same distance or different distances. The adjustment of the spacing can be adjusted by means of an adjusting device which can be driven by means of a motor which is controlled by a controller.
For example, the play system provides different play items for different levels of runners. On the snowmobile, a competition specified area with universality is established for different competition items, and a uniform horizontal and vertical coordinate is established in the specified area. The transmitters and the receivers of the correlation sensors are respectively arranged at the front end and the rear end of a snow blanket of the indoor simulation skiing machine, 12 groups of correlation straight lines formed by the transmitting end and the receiving end are parallel to the snow blanket, the sensors on the left side and the right side are arranged at fixed intervals, and the distance between every two sensors is 15 cm. Compiling fixed serial numbers for each beam of correlation straight lines, wherein, for example, the sensors arranged on the left side are respectively numbered as L1, L2, L3 … …, R1, R2 and R3 … …, according to the game items, a plurality of same standard game specified areas formed by correlation straight lines with different numbers are arranged for each game, and the correlation straight lines are combined in the same way, for example, the game comprises two correlation straight lines with the distance of 2 m; the coordinates of the specified areas are the same, for example, the competition interval is 4m by 4m, so that the same competition items can be adapted to the simulated skiing machines of various models, and meanwhile, more types of competition items are suitable to be added, for example, richer competition items, such as large rotation items, can be set according to the distance between the opposite straight lines on the left side and the right side; e.g., two diagonal lines of L1 and R1, e.g., a small revolution item, e.g., two diagonal lines of L3 and R3; the size is freely converted by rotation, such as the items comprising four correlation straight lines of L1, R1, L3 and R3. In addition, a standard competition area consisting of correlation straight lines with different numbers can be automatically generated according to the type of the snowmobile and the type of the competition, for example, on a competition project with a competition interval of 3m by 3m on the snowmobile 1, the competition comprises two correlation straight lines with the interval of 2.1m, the two correlation straight lines can consist of the correlation straight lines of L1 and R7, and the two correlation straight lines can also consist of L2 and R6; l7, R1; any row of L6, R2, etc. is formed by the combination of the bijective straight lines with the combination interval of 2.1 m.
When a user carries out a competition on the snowmobile simulator, the opposite-transmitting sensors acquire data signals of each pair of opposite-transmitting sensors, the data signals can be 0 and 1, 0 represents that an obstacle exists, and a receiver cannot receive the signals; 1 represents that the receiver is able to receive the signal.

For example, the number of the piles wound by the user can be set, and in this mode, the score is higher when the number of the piles wound is larger in a certain time. The fixed number and timing mode can be that the time is counted after the user passes through the fixed number of equipment or finishes the fixed number of actions, and the scoring is carried out according to the time.
