DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only some embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.
[0023] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0024] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "set", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0025] In the prior art, a sensing device is usually provided in a display device. The sensing device can usually be enabled after the display device enters the standby state and the screen is turned off, and is used to detect the human body movement status around the display device, so as to control the display device to exit the standby state and turn on the screen and operate normally when it is detected that someone enters the detection range around the display device. In practice, the sensing device can refer to detecting human body movement within a corresponding range through a pyroelectric infrared sensor, or detecting human body movement within a corresponding range through other types of sensors, which is not limited herein.
[0026] The defect of the prior art is that since users usually cannot quickly leave the detection range of the sensing device before the display device enters the standby state, it is easy for the display device to immediately detect that the user is still within its detection range after entering the standby state, thus misjudging that it is necessary to exit the standby state and turn on the screen at this time. This will cause waste of energy during the subsequent process of waiting for the display device to enter the standby state, resulting in a relatively high usage cost of the sensing device. In one example, after the user controls the display device to enter the standby state, during the process of the display device transitioning from the powered-on state to the standby state, if the user has not yet left the detection range of the sensing device of the display device, then when the user subsequently leaves this detection range, the user's body movement is detected by the sensing device, triggering the display device to exit the standby state and resume the powered-on state. This will cause the display device to be unable to remain in the standby state after the user leaves, but will remain lit and usually only automatically enter the standby state when no user operation is detected within a certain period of time after being lit. Even in some display devices with certain settings, they will always remain lit, wasting energy and resulting in a relatively high usage cost.
[0027] In response to this, the present application proposes a sensing device, which can be the above-mentioned display device or a part of the above-mentioned display device. When the duration of the processing module entering the standby state is relatively short, the connection between the sensing module and the processing module is disconnected, thereby disabling the sensing module. And when the duration of the processing module entering the standby state is relatively long, the connection between the sensing module and the processing module is conducted, thereby restoring the normal use of the sensing module. Based on the above method, it is possible to delay the activation of the sensing module to detect human movement after the processing module enters the standby state, thereby reducing the possibility that the sensing module misjudges that it is necessary to control the processing module to exit the standby state because the user has not quickly left after the user controls the processing module to enter the standby state. That is, it reduces the possibility of energy waste and reduces the usage cost of the sensing device.
[0028] See Figure 1 , Figure 1 FIG. is one of the structural schematic diagrams of an embodiment of the sensing device of the present application. The sensing device can specifically be the above-mentioned display device or a part of the above-mentioned display device. The above-mentioned display device can specifically be an intelligent interactive flat panel, a computer display screen, or other types of display devices, which are not limited herein.
[0029] As Figure 1 shown, the sensing device includes a clock module 11, a processing module 12, a switch module 13, and a sensing module 14.
[0030] The clock module 11 has an interrupt signal output terminal.
[0031] Among them, the clock module 11 can specifically be a clock chip, such as an RTC (Real Time Clock) chip. In one example, refer to Figure 2 , Figure 2 which is a schematic structural diagram of an embodiment of the RTC chip of the present application. As shown in Figure 2 , the RTC chip may include a 32KHZ output control circuit, an oscillator, a time adjustment circuit, a frequency division unit, a stop oscillation detection unit, an interrupt control unit, a comparator A, a comparator B, a ring register A, a ring register B, a time count register, an internal address register, and an I2C interface unit. The connection relationship is as shown in Figure 2 .
[0032] The oscillator can receive the crystal oscillator output signal OSCIN of the crystal oscillator circuit and output a crystal oscillator feedback signal OSCOUT.
[0033] The interrupt control unit can have two interrupt signal output terminals to respectively output a first interrupt output signal INTRA and a second interrupt output signal INTRB. The processing module 12 usually needs to occupy the signal output by one of the interrupt signal output terminals. For example, it is connected to the interrupt signal output terminal corresponding to the second interrupt output signal INTRB to perform corresponding timing in the operations it needs to perform.
[0034] The I2C interface unit can be connected to the processing module 12. The processing module 12 can set the interrupt function or other functions of the RTC chip through the SCL (Serial Clock Line) and SDA (Serial Data). For example, it can adjust the parameters of the RTC chip during the process of turning on the switch module 13 after a preset duration when the processing module 12 is in standby. The preset duration can be set to 5 seconds, or 5 minutes, or other durations, which is not limited here.
[0035] The processing module 12 is connected to the clock module 11.
[0036] Among them, the processing module 12 can specifically be a TV card chip (TV chip) in a TV, or the main chip in a smart interactive tablet, or the main chip in other types of devices, which is not limited here.
[0037] The processing module 12 can set the interrupt functions corresponding to the two interrupt signal output terminals of the clock module 11 through the connection with the clock module 11. The clock module 11 can receive the signal sent by the processing module 12 when it enters the standby state through the connection with the processing module 12, so as to determine the moment when the processing module 12 enters the standby state, and thus record the duration when the processing module 12 enters the standby state.
[0038] In one example, the display device is a smart interactive flat panel, and the sensing device is a device inside the smart interactive flat panel. Among them, the TV card chip in the sensing device is usually used to decode the received TV signal or other types of video signals, and then the display device of the smart interactive flat panel can perform corresponding screen display based on the decoded signal. For the sensing device, by connecting the clock module 11 to the TV card chip, it can be determined whether the user controls the TV card chip to enter the standby state and the duration of the TV card chip entering the standby state, so as to record the duration of the TV card chip entering the standby state for subsequent use.
[0039] The driving end of the switch module 13 is connected to the interrupt signal output end, and the first end of the switch module 13 is connected to the processing module 12. The sensing module 14 is connected to the second end of the switch module 13.
[0040] Among them, the interrupt signal output end of the clock module 11 can specifically be the output end for outputting the first interrupt output signal INTRA or the second interrupt output signal INTRB described in the foregoing embodiments, which is not limited herein.
[0041] The sensing module 14 is used to output a sensing signal when human movement is detected within a corresponding detection range.
[0042] Among them, the corresponding detection range can specifically refer to the detection range of the sensing module 14, that is, the sensing module 14 is specifically used to output a sensing signal when human movement is detected within its detection range. For example, when the sensing module 14 is a human infrared sensor, the sensing module 14 is specifically used to output a sensing signal when human movement is detected within its human infrared detection range. The sensing module 14 can also be other types of modules with sensing capabilities, which is not limited herein.
[0043] When the duration of the processing module 12 entering the standby state is not greater than the preset duration threshold, the switch module 13 is disconnected, and when the duration of the processing module 12 entering the standby state is greater than the preset duration threshold, the switch module 13 is turned on, and the processing module receives the sensing signal through the switch module.
[0044] Among them, the clock module 11 can be used to send a disconnection signal to the switch module 13 when the duration of the processing module 12 entering the standby state is not greater than the preset duration threshold, so that the switch module 13 is disconnected, and when the duration of the processing module 12 entering the standby state is greater than the preset duration threshold, send a conduction signal to the switch module 13 to make the switch module 13 conductive, and the processing module 12 receives the sensing signal through the switch module 13.
[0045] Within a preset duration threshold at the very beginning when the device where the processing module 12 is located (such as a TV) enters the standby state, the switch module 13 is disconnected, so that even if the sensing module 14 outputs a sensing signal, the processing module 12 cannot receive this sensing signal. Moreover, after a preset duration threshold at the very beginning when the device where the processing module 12 is located (such as a TV) enters the standby state, the switch module 13 is turned on, enabling the processing module 12 to have the ability to receive the sensing signal, that is, controlling the processing module 12 to start enabling the sensing module 14 to detect human movement within the detection range.
[0046] Based on the above method, within the initial period when the processing module 12 enters the standby state, it is possible to reduce the generation of sensing signals caused by the user not having had time to leave the detection range of the sensing module 14, and further reduce the possibility of the processing module 12 receiving the sensing signal and exiting the standby state, thereby reducing the duration of the display device where it is located turning on the screen due to the processing module 12 entering and quickly exiting the standby state, reducing energy waste, and achieving the reduction of the usage cost of the sensing device.
[0047] Different from the prior art, in the technical solution of the present application, a switch module is provided between the processing module and the sensing module, and the clock module can record the duration when the processing module enters the standby state. When the duration when the processing module enters the standby state is not greater than the preset duration threshold, the switch module is controlled to disconnect, and when the duration when the processing module enters the standby state is greater than the preset duration threshold, the switch module is controlled to turn on, so that the sensing signal output by the sensing module will not be sent to the processing module within the preset duration threshold, that is, the processing module will not exit the standby state due to receiving the sensing signal within the preset duration threshold after entering the standby state, achieving the effect of delaying the enabling of the sensing module to detect human movement after the processing module enters the standby state, reducing the possibility of the processing module quickly exiting the standby state because the user is still within the detection range of the sensing module within a relatively short duration when the processing module enters the standby state, thereby reducing energy waste and further reducing the usage cost of the sensing device.
[0048] In one embodiment, refer to Figure 3 , Figure 3 is the second schematic structural diagram of an embodiment of the sensing device of the present application. As Figure 3 shown, the switch module 13 includes a first switch tube 1301 and a second switch tube 1302.
[0049] The first end of the first switch tube 1301 is used to receive the first power supply voltage signal, and the driving end of the first switch tube 1301 is connected to the interrupt signal output end.
[0050] The driving end of the second switching tube 1302 is connected to the second end of the first switching tube 1301. The first end of the second switching tube 1302 is connected to the sensing module 14, and the second end of the second switching tube 1302 is connected to the processing module 12.
[0051] Specifically, V1 may specifically refer to a first power supply voltage signal. The first power supply voltage signal V1 is a high-level signal that can be provided when the processing module 12 enters the standby state. The driving end of the first switching tube 1301 can be connected to an interrupt signal output end of the clock module 11. For example, through this connection relationship, when the duration of the processing module 12 in the standby state is greater than a preset duration threshold, the clock module 11 can send the first interrupt output signal INTRA to the driving end of the first switching tube 1301 to conduct its first end and second end.
[0052] Among them, the first interrupt output signal INTRA can be a low-level signal. The first switching tube 1301 is a switching tube that conducts when the level is low, such as a PNP triode or other switching tubes that conduct when the level is low, which is not limited here.
[0053] The second switching tube 1302 can be a switching tube that conducts when the level is high, such as an NMOS tube or other switching tubes that conduct when the level is high, which is not limited here.
[0054] In an example, the first switching tube 1301 can specifically be a triode that conducts when the level is low. The driving end of the first switching tube 1301 can specifically be the base (B, base) of the triode. The first end of the first switching tube 1301 can specifically be the emitter (E, emitter) of the triode, and the second end of the first switching tube 1301 can specifically be the collector (C, collector) of the triode.
[0055] The second switching tube 1302 can specifically be a field effect tube that conducts when the level is high. The driving end of the second switching tube 1302 can specifically be the gate G of the field effect tube. The first end of the second switching tube 1302 can specifically be the source S of the field effect tube, and the second end of the second switching tube 1302 can specifically be the drain D of the field effect tube.
[0056] After the first end and the second end of the first switching tube 1301 are conducted, the driving end of the second switching tube 1302 can receive the first power supply voltage signal V1, thereby enabling the second switching tube 1302 to conduct. At this time, if the sensing module 14 detects human movement to generate a sensing signal, the sensing signal can be sent to the processing module 12 through the switching module 13. That is, after the duration of the processing module 12 in the standby state is greater than the preset duration threshold, the sensing signal generated by the sensing module 14 can be sent to the processing module 12.
[0057] Based on the above method, it can play a role in delaying the startup of the sensing module 14 after the processing module 12 enters the standby state, thereby reducing the duration of the display device where the processing module 12 is located turning on the screen due to the processing module 12 entering and quickly exiting the standby state, reducing energy waste, and achieving a reduction in the usage cost of the sensing device.
[0058] Optionally, as Figure 3 shown, the switch module 13 further includes a first resistor 1303 and a second resistor 1304.
[0059] One end of the first resistor 1303 is connected to the clock module 11, and the other end of the first resistor 1303 is connected to the driving end of the first switch tube 1301.
[0060] One end of the second resistor 1304 is connected to the other end of the first resistor 1303, and the other end of the second resistor 1304 is connected to the first end of the first switch tube 1301.
[0061] Specifically, based on the above settings of the first resistor 1303 and the second resistor 1304, it is possible to perform voltage division processing on the voltage of the first power supply voltage signal V1, so as to reduce the possibility that the driving end of the first switch tube 1301 directly receives a voltage signal with too high a voltage and causes the first switch tube 1301 to be damaged, thereby improving the reliability of the sensing device.
[0062] Furthermore, as Figure 3 shown, the switch module 13 further includes a third resistor 1305 and a first capacitor 1306.
[0063] One end of the third resistor 1305 is connected to the second end of the first switch tube 1301, and the other end of the third resistor 1305 is connected to the driving end of the second switch tube 1302.
[0064] One end of the first capacitor 1306 is connected to the other end of the third resistor 1305, and the other end of the first capacitor 1306 is grounded.
[0065] Specifically, based on the above settings of the third resistor 1305 and the first capacitor 1306, it is possible to filter the signal received by the driving end of the second switch tube 1302, so as to reduce stray signals, improve the accuracy of the signal received by the driving end of the second switch tube 1302, reduce the possibility of mis-conduction or mis-disconnection of the second switch tube 1302, and further improve the reliability of the sensing device.
[0066] Even further, as Figure 3 shown, the switch module 13 further includes a fourth resistor 1307.
[0067] One end of the fourth resistor 1307 is connected to the other end of the third resistor 1305, and the other end of the fourth resistor 1307 is used to receive a second power supply voltage signal, which is the power supply voltage signal output when the processing module 12 is in the operating state.
[0068] Specifically, the second power supply voltage signal V2 can specifically be a signal that is floating when the processing module 12 enters the standby state, but is at a high level when the processing module 12 exits the standby state and enters the operating state.
[0069] Based on the above setting of the fourth resistor 1307, when the processing module 12 exits the standby state and enters the operating state, the second switching transistor 1302 can be stably turned on. At this time, the processing module 12 can perform operations required in the operating state based on the human body movement within its detection range by the sensing module 14, improving the stability of the processing module 12 using the sensing module 14 in the operating state, and further improving the reliability of the sensing device.
[0070] Optionally, as Figure 3 shown, the switch module 13 further includes a fifth resistor 1308.
[0071] One end of the fifth resistor 1308 is connected to the second end of the second switching transistor 1302, and one end of the fifth resistor 1308 is grounded. The other end of the fifth resistor 1308 is used to receive a second power supply voltage signal, which is the power supply voltage signal output when the processing module 12 is in the operating state.
[0072] Specifically, when the processing module 12 exits the standby state and enters the operating state, through the cooperation of the high-level second power supply voltage signal V2 and the sensing signal, the processing module 12 can have a greater discrimination when the sensing signal appears and does not appear, thereby improving the accuracy of sensing detection and further improving the reliability of the sensing device.
[0073] Optionally, as Figure 3 shown, the switch module 13 further includes a sixth resistor 1309.
[0074] One end of the sixth resistor 1309 is connected to the first end of the second switching transistor 1302, and the other end of the sixth resistor 1309 is connected to the sensing module 14.
[0075] Specifically, based on the setting of the sixth resistor 1309, overcurrent protection can be provided for the sensing module 14 or the second switching transistor 1302, reducing the possibility of damage caused by excessive current and improving the reliability of the sensing device.
[0076] Optionally, the sensing module 14 includes a pyroelectric infrared sensor, which is used to output a sensing signal when detecting human body movement.
[0077] Specifically, the human body infrared sensor may specifically refer to a pyroelectric infrared sensor, which can be used to detect whether there is human movement within its detection range, so as to judge the movement parameters (such as speed change, position change, etc.) of the people within its detection range.
[0078] Furthermore, the sensing signal is a low-level signal, and the conduction direction of the body diode of the second switching tube 1302 is from the first end of the second switching tube 1302 towards the second end of the second switching tube 1302.
[0079] Specifically, the sensing module 14 can output a high-level signal when no human movement is detected, and output a low-level sensing signal when human movement is detected. The high-level signal can be directly sent to the processing module 12 through the body diode, so as to avoid the situation that the processing module 12 misidentifies that it has received the sensing signal when it does not receive the high-level signal, improving the accuracy of the sensing device.
[0080] In one example, the sensing device may specifically be a device in a display device, and the display device may specifically be an intelligent interactive flat panel.
[0081] Such as Figure 1 And Figure 3 As shown, in advance, the user can control the processing module 12 (such as a TV card chip) to perform I2C communication settings on the clock module 11, and set the clock module 11 to output a corresponding first interrupt output signal INTRA through its interrupt signal output terminal 5 seconds after detecting that the processing module 12 enters the standby state.
[0082] In practical applications, when the user controls the intelligent interactive flat panel to enter the standby mode, the processing module 12 will enter the standby state and send a corresponding signal to the clock module 11 to make the clock module 11 start to record the duration of the processing module 12 entering the standby state. 5 seconds after the processing module 12 enters the standby state, the clock module 11 will output a corresponding first interrupt output signal INTRA to the driving end of the first switching tube 1301 through its interrupt signal output terminal to turn on the first switching tube 1301.
[0083] After the first switching tube 1301 is turned on, the first power supply voltage signal V1 received at the first end of the first switching tube 1301 is sent to the second switching tube 1302 to turn on the second switching tube 1302.
[0084] When the second switching transistor 1302 is turned off, even if the sensing module 14 detects human activities and emits a sensing signal, the sensing signal cannot be sent to the processing module 12 through the second switching transistor 1302. That is, within 5 seconds after the processing module 12 enters the standby state, the sensing module 14 is disabled. At this time, even if the user is still walking within the detection range of the sensing module 14, the processing module 12 cannot exit the standby state due to receiving the sensing signal and cause accidental startup.
[0085] After the second switching transistor 1302 is turned on, after the sensing module 14 detects human activities and emits a sensing signal, the sensing signal can be sent to the processing module 12 through the second switching transistor 1302 to realize the detection of human activities. That is, after 5 seconds after the processing module 12 enters the standby state, when the sensing module 14 detects that the user is walking within its detection range, a sensing signal with a low level will be generated and sent to the processing module 12 through the second switching transistor 1302. After receiving the sensing signal with the low level, the processing module 12 can recognize that there is human movement within the detection range of the sensing module 14. At this time, the processing module 12 will exit the standby state to realize startup wake-up for the user to use normally.
[0086] In addition, in an example, 5 seconds after the clock module 11 detects that the processing module 12 enters the standby state, the clock module 11 outputs a corresponding first interrupt output signal INTRA to the switch module 13 through its interrupt signal output terminal to turn on the switch module 13.
[0087] After the sensing module 14 is turned on by the switch module 13, if it detects human activities, it will send a sensing signal to the processing module 12 through the turned-on switch module 13 to trigger the processing module 12 to exit the standby state. Among them, after the processing module 12 exits the standby state, it can enter the running state or other types of non-standby states, which are not limited here.
[0088] After the processing module 12 exits the standby state, the clock module 11 stops outputting the corresponding first interrupt output signal INTRA to the switch module 13 through its interrupt signal output terminal to turn off the switch module 13.
[0089] Subsequently, if it is detected again that the processing module 12 enters the standby state, the steps of "after the clock module 11 detects that the processing module 12 enters the standby state for 5 seconds, the clock module 11 outputs a corresponding first interrupt output signal INTRA to the switch module 13 through its interrupt signal output terminal to turn on the switch module 13" and subsequent steps are returned for execution, achieving the effect of delaying the activation of the sensing module for detecting human motion after each time the processing module 12 enters the standby state. Furthermore, it reduces the possibility that the processing module 12 quickly exits the standby state because the user is still within the detection range of the sensing module 14 during the short duration when the processing module 12 enters the standby state, thereby reducing energy waste and further reducing the usage cost of the sensing device.
[0090] It should be noted that the above-mentioned 5-second duration is specifically an example and can also be replaced with 10 seconds, 1 minute, 1 hour, and other durations, which can be determined according to actual needs and are not limited here.
[0091] This application also proposes a display device. Refer to Figure 4 , Figure 4 is a schematic structural diagram of an embodiment of the display device of this application. As Figure 4 shown, the display device 20 includes a sensing device 10, and the sensing device 10 can be the sensing device in any of the previous embodiments and will not be elaborated here.
[0092] Specifically, the display device can specifically be a television, or a smart interactive tablet, or other types of devices with a display function, which are not limited here.
[0093] Different from the prior art, in the technical solution of this application, a switch module is provided between the processing module and the sensing module, and the clock module can record the duration when the processing module enters the standby state. When the duration when the processing module enters the standby state is not greater than a preset duration threshold, the switch module is controlled to disconnect, and when the duration when the processing module enters the standby state is greater than the preset duration threshold, the switch module is controlled to turn on. Thus, the sensing signal output by the sensing module will not be sent to the processing module within the duration of the preset duration threshold, that is, the processing module will not exit the standby state due to receiving the sensing signal within the duration of the preset duration threshold after entering the standby state, achieving the effect of delaying the activation of the sensing module for detecting human motion after the processing module enters the standby state, reducing the possibility that the processing module quickly exits the standby state because the user is still within the detection range of the sensing module during the short duration when the processing module enters the standby state, thereby reducing energy waste and further reducing the usage cost of the sensing device.
