Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multi-functional sports venues, in particular to a sports venue light position quick switching device and method. BACKGROUND

[0002] With the popularity of multi-functional sports venues, a single venue needs to frequently switch between basketball, badminton and table tennis events. According to the "Gymnasium Lighting Design and Detection Standard" (JGJ 153-2016) and the International Sports Federation (GAISF) specification requirements, there are different core indicators for lighting in different events: basketball events require a symmetrical four-side light distribution scheme to ensure that the vertical illuminance is ≥ 1500lx, while table tennis events require horizontal light distribution and control of the glare index UGR≤19; in terms of beam angle, collective ball games require a 25°-60° wide beam to cover, and track and field events rely on a 15° narrow beam to achieve precise projection.

[0003] However, the existing sports venue lighting system has three main defects: first, to meet the needs of multiple scenes, multiple independent lighting systems (such as basketball and table tennis double light array) are forced to be installed, resulting in a 40%-65% increase in equipment cost; second, temporary erection of a lifting frame requires a lot of time for manual adjustment, which violates the ≤90-minute event switching standard specified by the International Basketball Federation (FIBA); third, fixed lamps will produce glare exceeding the standard in non-adapted scenes, with a measured UGR value fluctuating by 22-28, which seriously violates the CIE S 017:2020 international lighting standard.

[0004] The industry technology evolution is facing a key bottleneck: the existing sports venue intelligent lighting system (such as the dimming scheme based on DMX512 protocol) can only adjust brightness and color temperature, and cannot solve the problem of lamp space pose reconstruction. For example: the rotating lamp head scheme only supports ±30° horizontal adjustment and lacks cross-region displacement capability; the lifting frame structure lacks three-dimensional space rotation freedom, resulting in a decrease in light uniformity, with a measured field area illuminance ratio greater than 1.8.

[0099] Embodiment Two

[0100] Please refer to Figure 20 The embodiment provides a sports stadium light position quick switching method, which is applied to a control host and includes the following steps:

[0101] Step 1: receiving a sports event mode switching instruction input by a user, judging whether the lifting platform needs to be rotated according to the sports event mode switching instruction; if the lifting platform needs to be rotated, lowering the lifting platform to the ground by a winch, disconnecting the lifting platform from the steel wire after the lifting platform is lowered to the ground, rotating the lifting platform by 90 degrees through a vehicle frame and connecting the lifting platform with the steel wire, and raising the lifting platform by the winch; if the lifting platform does not need to be rotated, directly entering step 2.

[0102] Specifically, it is judged whether the position of the lifting platform needs to be adjusted according to the sports event to be held; if adjustment is needed, the lifting platform is lowered to the moving trolley by the control host, the steel wire connecting device is removed, the trolley is pushed to the position to be adjusted, the steel wire connecting device is hung, and finally the lifting platform is raised to the position by the control host (as shown in Figure 21

[0103] After the lifting platform is raised to the position, a start button is pressed, the lifting platform is powered on, the system starts self-checking and initial parameter setting, port setting and polling reading of ModBus data such as motor frequency and encoder value, and then a mode switching instruction button is pressed.

[0104] Step 2: obtaining the horizontal rotation angle and the pitch rotation angle of each gimbal on the lifting platform according to the sports event mode switching instruction.

[0105] Step 3: judging whether the horizontal direction needs to be adjusted according to the horizontal rotation angle and the gimbal horizontal angle of the pre-set sports event.

[0106] ​Step 4: If adjustment is needed, calculate the horizontal angle value and direction to be adjusted according to the horizontal rotation angle and the preset horizontal angle of the sports event;

[0107] Step 5: Adjust the horizontal angle of the holder according to the horizontal angle value and direction;

[0108] Specifically, after calculating the horizontal angle value and direction, they are converted into pulse numbers and written into the motor controller, and an execution command is written into the motor controller, and the motor is automatically adjusted to the mode angle.

[0109] Step 6: Determine whether the vertical direction needs to be adjusted according to the pitch rotation angle and the preset vertical angle of the sports event holder;

[0110] Step 7: If adjustment is needed, calculate the vertical angle value and direction to be adjusted according to the pitch rotation angle and the preset vertical angle of the sports event holder;

[0111] Step 8: Adjust the vertical angle of the holder according to the vertical angle value and direction.

[0112] Specifically, after calculating the vertical angle value and direction, they are converted into pulse numbers and written into the motor controller, and an execution command is written into the motor controller, and the motor is automatically adjusted to the mode angle.

[0113] In this embodiment, one side of the main interface of the control host is a mode key, and the other side displays the lifting platform and the number of holders on each lifting platform. Taking a standard basketball court as an example, it includes 8 sets of lifting platforms, and each platform is deployed with 6 holders. The display form can be switched by switching the display key. The lifting platform and the number of holders can be displayed, and the platform position in the field can also be displayed. For example, Figure 22 and Figure 23 As shown in the figure, the figure shows the status display and switching under mode 1 (basketball court).

[0114] In this embodiment, the platform to be operated or viewed can be selected in the touch screen interface and clicked (as shown in Figure 24 and Figure 25 After being selected and clicked, the selected platform interface window is entered. In this window, the state of the holder deployed on the lifting platform (sensor encoder value), the control signal of the horizontal and pitch motor controller (drive pulse and pulse number), the set target value and motor state value (as shown in Figure 26 In each preset mode, the angle target value of the holder has been preset, and the independent control of the horizontal and pitch of the holder can be set in the target value when needed. When mode switching is needed to vertically rotate a certain lifting platform, the platform needs to be lowered and rotated to the predetermined position by the trolley before being raised and lowered. Here, the lifting control is performed by the up and down keys.

[0115] After the platform completes the vertical rotation and rises to the corresponding position, the docking is completed. The corresponding mode is selected for switching, and mode 2 (two badminton court lighting) is taken as an example here. Please refer to Figure 27 and Figure 28 , and click the mode 2 button of the touch screen for selection. In this mode, the corresponding gimbals on all lifting platforms rotate to the corresponding angles, and the lamps carried on the gimbals are controlled to the preset brightness by the DMX512 controller.

[0116] The following takes a specific scene switching as an example to specifically illustrate how the scene switching is performed in this embodiment:

[0117] Scene switching mode example 1:
