Assume that three reception times and corresponding photoelectric switches are respectively:
5:10, corresponding to the first photoelectric switch;
5.11, corresponding to the second photoelectric switch;
5.13, corresponding to the first photoelectric switch;
and 5.14, corresponding to the second photoelectric switch.
The difference between the time when the control unit receives the electrical signal sent by the first photoelectric switch and the time when the control unit receives the electrical signal sent by the second photoelectric switch can be understood as 1 minute according to the photoelectric switch corresponding to each receiving time in the first time difference, wherein the first time difference is 5:11-5:10=1 minute. Assuming that the time when the light beam emitted by the photoelectric switch is blocked is the same as the time when the control unit receives the electric signal emitted by the photoelectric switch, the blade blocks the light beam emitted by the first photoelectric switch, and 1 minute passes from when the blade blocks the light beam emitted by the second photoelectric switch.
The second time difference is 5:13-5:11=2 minutes, which means that the blade blocks the light beam emitted by the second photoelectric switch until the blade blocks the light beam emitted by the first photoelectric switch for 2 minutes.
The third time difference is 5:14-5:13=1 minute, which means that the blade blocks the light beam emitted by the first photoelectric switch until the blade blocks the light beam emitted by the second photoelectric switch for 1 minute.
When the control unit determines the rotation direction of the rotating shaft according to the magnitude of the two adjacent time length difference values and the photoelectric switch corresponding to each receiving time in each time length difference value, the control unit can save the corresponding relationship between the magnitude of the two adjacent time length difference values, the receiving sequence corresponding to the photoelectric switch and the forward and backward rotation, and determine the forward and backward rotation according to the magnitude of the two adjacent time length difference values and the receiving sequence corresponding to the photoelectric switch which are currently determined.
Assuming that two adjacent time length differences are the first time length difference and the second time length difference, whether the relationship between the two time length differences is positive rotation or negative rotation is determined, and the relationship between the two time length differences and the second time length difference is related to the placement positions of the two photoelectric switches, once the fixed positions of the two photoelectric switch tubes are determined, the user can know who is according to the two time length differences, and whether the two time length differences are positive rotation or negative rotation is determined.

The control unit is connected with the forward and reverse rotation prompting device through a circuit, and the connection belongs to the prior art, and details are omitted in the embodiment of the invention.
The control unit can control the forward and backward rotation prompting device to correspondingly prompt after determining the forward and backward rotation of the rotating shaft. If the control unit determines that the rotating shaft rotates positively, the positive and negative rotation prompting device is controlled to prompt the rotating shaft to rotate positively, and if the control unit determines that the rotating shaft rotates negatively, the positive and negative rotation prompting device is controlled to prompt the rotating shaft to rotate negatively. The process of controlling the forward and reverse rotation prompting device to perform corresponding prompting by the control device belongs to the prior art, and details are not repeated in the embodiment of the invention.
In an embodiment of the present invention, the forward and reverse rotation prompting device includes: a forward rotation indicator lamp and a reverse rotation indicator lamp;
and the controller is used for controlling the forward rotation indicator lamp or the reverse rotation indicator lamp to be lightened when the rotation direction of the rotating shaft is determined.

based on the above embodiments, in the embodiments of the present invention, the positional relationship between the photoelectric switch and the blade may be: the blade forms a circular plane when rotating, the projection point of the light beam emitted by each photoelectric switch on the first plane where the circular plane is located in the circular plane, and the projection point of the rotating shaft on the circular plane and the projection points of the two light beams on the circular plane are not located on the same straight line.
The circular plane formed when the blade rotates is only a circle swept by the blade when the blade rotates, the plane in which the circular plane is located is called a first plane, the projection of the light beam on the first plane is a point, namely the projection point, and two corresponding projection points of two light beams are both located in the circular plane. The projection of the rotating shaft on the circular plane is a projection point. The three proxels are not in a straight line. For clarity of description, the projection points will be simply converted, without affecting the overall concept of the present invention.
The two photoelectric switches are fixed on the same second inner side perpendicular to the first inner side wall, and the projection of the rotating shaft on the second inner side wall is positioned on a line segment formed by the projection points of the two light beams on the second inner side wall.
Taking the example that two photoelectric switches are positioned on the top side wall as an example, the relative positional relationship among the light beam, the rotation shaft and the blade can be seen from the top view, the front view and the right view as shown in fig. 4. The light beam emitted by the first photoelectric switch is a light beam 1, and the light beam emitted by the second photoelectric switch is a light beam 2. On the top side wall, the projection points of the two light beams are not in the same straight line with the projection points of the rotating shaft.
When the blades rotate, the light beams 1 and 2 are shielded, the corresponding first photoelectric switch and second photoelectric switch send electric signals to the control unit, and the control unit determines the rotating direction of the rotating shaft according to the first time length difference value and the second time length difference value.
If the first time length difference value is smaller than the second time length difference value, the rotating shaft rotates positively; if the first time length difference is greater than the second time length difference, the rotating shaft is reversed.
Simple modifications of the structure described with reference to fig. 4 are also within the scope of the embodiments of the present invention.
