Embodiment

As shown in Figure 1, a kind of video eyeglasses of the present utility model, comprises video player, head-mounted display and power module, and described power module comprises lithium battery and optocoupler; In described video player, be provided with JZ4755 video processor, FM module, SD card, TF card and button cell, 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 to respectively on JZ4755 video processor; 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 to respectively on feed circuit and some micro-displays; Described optocoupler is electrically connected to 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 the relative level changing between PIN1 and PIN2, controls the on off operating mode between PIN3 and PIN4.During use, the IO that PIN1 connects processor controls mouth, PIN2 ground connection, PIN3 connects lithium battery, and PIN4 connects feed circuit, because the level of processor IO mouth is 3.3VTTL level, so when IO mouth be 3.3V(now logic for ' 1 ') time, PIN3 and PIN4 conducting, head-mounted display is opened; When IO mouth is now logic ' 0 ' of 0V() time, PIN3 and PIN4 close, and head-mounted display is closed.

In using the process of 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 user's operation requests for a long time, such as surpassing 1 minute (comprising 1 minute), JZ4755 video processor controls IO mouth 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 in DOZE pattern lower time, once universal I/O or interruption (also other has the interruption of the input/output port of capturing function) be detected, be triggered, processor is controlled the unlatching of IO mouth, head-mounted display restores electricity, and enters normal operating conditions.

2, IDLE pattern.As shown in Figure 5, when JZ4755 video processor is operated under normal mode of operation, once wake-up switch by short by (time that presses the button maintenance is less than 2 seconds), JZ4755 video processor controls IO mouth and cuts out, optocoupler is closed, head-mounted display loses power supply, and micro-display, in off-position, enters in IDLE pattern.

As shown in Figure 6, when JZ4755 video processor is in IDLE pattern lower time, once detect wake-up switch by short by (time that presses the button maintenance is less than 2 seconds), processor is controlled IO mouth and is opened, head-mounted display restores electricity, and enters normal operating conditions.

3, SLEEP pattern.As shown in Figure 7, when JZ4755 video processor is operated under normal mode of operation, once its wake-up switch, be long pressed (time that presses the button maintenance is greater than 4 seconds), JZ4755 video processor controls IO mouth and cuts out, optocoupler is closed, head-mounted display loses power supply, and micro-display, in off-position, enters in SLEEP pattern.

As shown in Figure 8, when JZ4755 video processor is in SLEEP pattern lower time, once wake-up switch be detected, be long pressed (time that presses the button maintenance is greater than 4 seconds), processor is controlled IO mouth and is opened, and head-mounted display restores electricity, and enters normal operating conditions.

In order further to verify superiority of the present utility model, existing video eyeglasses process to be improved, and detected the power consumption under 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 utility model, original spectacle player is done after corresponding modify, do not closing micro-display, the Overall Power Consumption of processor under SLEEP mode state is:

3, according to structure of the present utility model, original spectacle player to be done after corresponding modify, the Overall Power Consumption under DOZE mode state is:

4, according to structure of the present utility model, original spectacle player to be done after corresponding modify, the Overall Power Consumption under IDLE mode state is:
