[0034] To address the problems existing in current technologies, a warning screen control system is proposed, such as... Figure 1 As shown, it includes:

[0035] The control unit 100 is electrically connected to the dual-color module 300 and is used to control the dual-color module 300 to display warning content;

[0036] The control unit 100 includes a microcontroller 101, a display driver card 103, and a lithium battery charging and discharging device 102.

[0037] The microcontroller 101 is electrically connected to the warning screen via the display driver card 103;

[0038] The lithium battery charging and discharging device 102 is electrically connected to the lithium battery 400 and the switching power supply 200. The switching power supply 200 is electrically connected to the dual-color module 300, the display driver card 103 and the microcontroller 101 respectively, so as to provide power to the dual-color module 300, the display driver card 103 and the microcontroller 101 respectively.

[0039] The microcontroller 101 is model STC8G1K08. The function of the microcontroller 101 is to receive the control signal from one function button 700, convert it into three signal outputs to control the display driver card 300. The display driver card 300 pre-stores the display content, and the preset display content can be quickly switched on-site through the function button 700.

[0041] The lithium battery charging and discharging device 102 is model BA-12.6V15A, which is responsible for converting the externally input 220V AC power into a 12.6V lithium battery 400 charging power supply, and controlling the discharge voltage of the lithium battery 400 to prevent damage to the lithium battery 400.

[0042] The lithium battery 400 is a 40AH 12.6V battery. The lithium battery 400 is electrically connected to the power indicator 500.

[0043] The vehicle power supply 600 is connected to the lithium battery charging and discharging device 102. The vehicle power supply 600 takes 12V AC power from the vehicle's cigarette lighter and converts it to 220V AC power to supply the lithium battery 400 for charging. The power indicator 500 is connected to the lithium battery 400 and the lithium battery charging and discharging device 102 to provide the remaining power of the lithium battery. If the power is insufficient in the field, the vehicle power supply 600 can be used for emergency charging.

In the unfolded state, the dual-color module 300 is perpendicular to the ground.

[0048] The bottom housing 1000 includes a rotating support foot 1001. In the folded state, the rotating support foot and the bottom housing 1000 overlap; in the unfolded state, the rotating support foot 1001 and the bottom housing 1000 form a cross shape to support standing.

[0050] The dual-color modules 300 are respectively installed on the upper rotating plate 800 and the lower rotating plate 900 to form an upper dual-color module 301 and a lower dual-color module 302. The upper dual-color module 301 and the lower dual-color module 302 are connected in series with the switching power supply 200 through a connecting wire, and then connected to the display driver card 103.

[0051] The warning screen designed in this utility model has a foldable rotating panel, which can be used as a display screen when unfolded, and can be stored in the trunk of a car for easy carrying when folded.
