Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in Figure 1, alarming device of the present invention, it comprises the solar panel 1 that is arranged on the lamp stand 4, be positioned at the lamp body 2 at lamp stand 4 middle parts, arrangement is arranged on the LED3 on the described lamp body 2, and LED3 gets blue three looks of reddish yellow, arranges to be provided with and forms the warning lamp array, the bottom of described lamp stand 4 is provided with charging control box 5, comprises charge controller and accumulator.
Control circuit has been installed in described lamp body 2 inside, comprises that 12V shown in Figure 2 changes DC-DC power transfer module 8, toggle switch 9, single chip machine controlling circuit 10, sensing module 11 and the LED driver module 12 of 5V.The input termination charge controller 6 of described DC-DC power transfer module 8, the described single chip machine controlling circuit 10 of described toggle switch 9 output terminations, described sensing module 11 output terminals also connect single chip machine controlling circuit 10, described LED driver module 12 input ends connect single chip machine controlling circuit 10, the described warning lamp array 13 of output termination.Described single chip machine controlling circuit 10 is by described DC-DC power transfer module 8 power supplies, and described warning lamp array 13 is directly powered by described charge controller 6 by accumulator.
Among Fig. 2, described charge controller 6 with electrical power storage in described accumulator 7, described accumulator 7 is supplied with warning lamp array 13 and DC-DC power transfer module 8 through described charge controller 6 with the 12V electricity, as shown in Figure 3, single chip machine controlling circuit is made up of single-chip microcomputer 14 and peripheral circuit thereof, described DC-DC power transfer module 8 is a switch power module, and power attenuation is lower, the power supply conversion efficiency height.12V voltage is converted to 5V through DC-DC power transfer module 8 and supplies with single-chip microcomputer 14, and described single-chip microcomputer 14 adopts the extremely low AVR single-chip microcomputer of power consumption.Described toggle switch 9 is connected to the I/O mouth that described single-chip microcomputer 14 has interrupt function, described sensing module 11, LED driver module (being the driven MOS pipe) 12 are connected to the I/O mouth of described single-chip microcomputer 14, and the output terminal of driven MOS pipe is connected to described warning lamp array 13.
