Embodiment
As shown in Figure 1, a kind of video eyeglasses of the present invention, comprises video player, head-mounted display and power module, and described power module comprises lithium battery and optocoupler; JZ4755 video processor, FM module, SD card, TF card and button cell is provided with in described video player, described video player housing is provided with wake-up switch and controls button, and described button cell, FM module, SD card, TF card, wake-up switch and control button are electrically connected on JZ4755 video processor respectively; Described head-mounted display comprises feed circuit, driving circuit and some micro-displays, and described driving circuit adopts TW8816 microprocessor as core devices, and described driving circuit is electrically connected on feed circuit and some micro-displays respectively; Described optocoupler is electrically connected with lithium battery, processor and feed circuit respectively.
As shown in Figure 2, described electrooptical device change-over circuit mainly comprises CPC1017N optocoupler type device, by changing the on off operating mode between relative level control PIN3 and PIN4 between PIN1 and PIN2.During use, the IO that PIN1 connects processor controls mouth, PIN2 ground connection, PIN3 connects lithium battery, and PIN4 connects feed circuit, and the level due to processor I/O port is 3.3VTTL level, so when I/O port be 3.3V(now logic for ' 1 ') time, PIN3 and PIN4 conducting, head-mounted display is opened; When I/O port is 0V(now logic ' 0 ') time, PIN3 and PIN4 closes, and head-mounted display is closed.
In the process using spectacle player, this video eyeglasses provides three kinds of different low-power consumption modes, and the criterion of three kinds of low-power consumption modes and method of operating are:
1, DOZE pattern.As shown in Figure 3, when described JZ4755 video processor is not when receiving the operation requests of user for a long time, such as more than 1 minute (comprising 1 minute), JZ4755 video processor controls I/O port and cuts out, optocoupler is closed, head-mounted display loses power supply, closes Presentation Function, enters in DOZE pattern.
As shown in Figure 4, when JZ4755 video processor is under DOZE pattern, once detect that general purpose I/O or interruption (may also be the interruption that other has the input/output port of capturing function) are triggered, then processor controls I/O port unlatching, head-mounted display restores electricity, and enters normal operating conditions.
2, IDLE pattern.As shown in Figure 5, when the work of JZ4755 video processor in the normal mode of operation, (time pressing the button maintenance is less than 2 seconds) is pressed by short once wake-up switch, JZ4755 video processor controls I/O port and cuts out, optocoupler is closed, head-mounted display loses power supply, and micro-display is in off-position, enters in IDLE pattern.
As shown in Figure 6, when JZ4755 video processor is under IDLE pattern, once wake-up switch be detected by short by (time pressing the button maintenance is less than 2 seconds), then processor controls I/O port unlatching, and head-mounted display restores electricity, and enters normal operating conditions.
3, SLEEP pattern.As shown in Figure 7, when the work of JZ4755 video processor in the normal mode of operation, be long pressed (time pressing the button maintenance is greater than 4 seconds) once its wake-up switch, JZ4755 video processor controls I/O port and cuts out, optocoupler is closed, head-mounted display loses power supply, and micro-display is in off-position, enters in SLEEP pattern.
As shown in Figure 8, when JZ4755 video processor is under SLEEP pattern, once detect that wake-up switch is long pressed (time pressing the button maintenance is greater than 4 seconds), then processor controls I/O port unlatching, and head-mounted display restores electricity, and enters normal operating conditions.
In order to verify superiority of the present invention further, by existing video eyeglasses through improving, and the power consumption under detecting different conditions, device testing result is as follows:
1, the Overall Power Consumption of original spectacle player is:
2, according to structure of the present invention, after making corresponding modify to original spectacle player, do not closing micro-display, the Overall Power Consumption that processor is under SLEEP mode state is:
3, according to structure of the present invention, after making corresponding modify to original spectacle player, the Overall Power Consumption under DOZE mode state is:
4, according to structure of the present invention, after making corresponding modify to original spectacle player, the Overall Power Consumption under IDLE mode state is:
5, according to structure of the present invention, after corresponding modify is done to original spectacle player, the Overall Power Consumption under SLEEP mode state
Can be found out by form above, based on the lithium battery that two groups of micro-displays and the head-mounted display of driving circuit and the video player of JZ4755 processor are test platform and a 1500mAh, head-mounted display circuit power consumption is at 450mW, in normal operation, account for about 30% of complete machine, but in the standby state, the electric current of video player is only about 200mW, the power consumption of head-mounted display accounts for about 70% of system, by adopting the invention of this patent, effectively can realize the power consumption control of head-mounted display under this holding state, thus reach the object of reduction system Overall Power Consumption.
The above is the preferred embodiment of the present invention, and for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are also regarded as protection scope of the present invention.
