Please refer to FIG. 1 , which is a system architecture diagram of a preferred embodiment of the present invention. The smart light sensing system includes a light sensing device 10 and a smart mobile device 20 .

The light sensing device 10 includes a light sensing component 11 , a first memory 12 , a first processor 13 , an indicator 14 , a first wireless transceiver 15 , and a battery 16 . The light sensing component 11, the first memory 12, the indicator 14 and the first wireless transceiver 15 are all connected to the first processor 13, and the battery 16 is used for supplying power (and forming an electrical connection) to the light sensing device 10. Other power consuming components include, but are not limited to, light sensing component 11, first memory 12, first processor 13, indicator 14 and first wireless transceiver 15. In other possible embodiments, the light sensing device may not include a battery and may be externally connected to the utility as its power source.

The light sensing component 11 is configured to sense the illuminance or color temperature of the surrounding environment and emit a light sensing signal. Preferably, the optical sensing signal converts the optical sensing signal of the analog signal into a digital signal via an analog digital converter.

The first memory 12, the first processor 13, the indicator 14, the first wireless transceiver 15 and the battery 16 can be, but are not limited to, integrated into a Programmable Logic Controller (PLC), and the indicator 14 can be In combination with at least one light-emitting element (such as an LED) or at least one buzzer or light-emitting element and a buzzer, the indicator 14 can be used to emit an indication signal such as light or sound. In the preferred embodiment, the first processor 13 can be used to sense the remaining charge of the battery 16 and generate a remaining charge signal.

The smart mobile device 20 can be, but is not limited to, a smart phone, a PDA or a tablet, and includes a human machine interface 21, a second memory 22, a second processor 23, a second wireless transceiver 24, and a Battery 25. The human interface 21, the second memory 22, and the second wireless transceiver 24 are all connected to the second processor 23, and the battery 25 is used to supply power to other power-consuming components of the smart mobile device 20, including but not limited to people. The device interface 21, the second memory 22, the second processor 23, and the second wireless transceiver 24. Similarly, in other possible embodiments, the smart mobile device may not include a battery and may be externally connected to the utility as its power source.

The user can operate the smart mobile device 20 through the human interface 21, and the human interface 21 usually includes a screen and an input component. In a common implementation, the human interface 21 can be a touch screen and a screen. The function with both input elements. In other possible implementations, the input element can be, but is not limited to, other physical keys, a keyboard, or a mouse.

The second memory 22 carries at least one of an upper limit value and a lower limit value of optical information (such as illuminance or color temperature) suitable for different usage scenarios. In a preferred embodiment, the optical information stored in the second memory 22 generally includes both an upper limit value and a lower limit value. In other possible implementations, part of the optical information stored in the second memory 22 includes only Upper limit or only lower limit.

As shown in FIG. 2, the human interface 21 is available for the user to select one of the usage scenarios. In this embodiment, the selection panel for using the context includes a location option 211 (eg, "home", "office", "outdoor", etc. And action options 212 (such as "writing", "reading", "watching TV", etc.), when the user selects a location option and an action option, in other words, when a particular usage context has been selected, it corresponds to the second memory. 22 corresponding optical information upper and lower limits.

In this embodiment, when the human interface 21 is in a detection mode and the user has selected a specific usage scenario, as shown in FIG. 3, the light sensing signals sensed by the light sensing component 11 are sequentially The first wireless transceiver 15 and the second wireless transceiver 16 are transmitted to the second processor 23, and the received light sensing signal is displayed by the second processor 23 to the human interface 21, and the human interface 21 is at this time. For example, the current usage scenario 213, the optical information upper and lower limit values 214 corresponding to the usage context 213, and the current optical sensing signal value 215 can be displayed. Meanwhile, the second processor 23 can also determine whether the optical sensing signal value is Between the upper and lower limits, and according to the judgment result, a brief comment message 216 (for example, "good" or "poor") is displayed on the human machine interface 21.

In addition, the smart mobile device 20 also feeds back the user's selection result of the use situation to the light sensing device 10. At this time, the second processor 23 transmits and stores at least one of the upper and lower optical information corresponding to the usage scenario selected by the user through the second wireless transceiver 24 and the first wireless transceiver 15 in sequence. In the first memory 12, the first processor 13 can compare the light sensing signal sensed by the light sensing component 11 with at least one of the optical information stored in the first memory 12 and the lower limit value. And according to the result of the comparison, the indicator 14 sends a corresponding indication signal.

For example, when the first processor 13 determines that the illuminance value sensed by the light sensing component 11 is between the upper and lower illuminances corresponding to the context selected by the user, the first processor 13 can control the indicator 14 to issue Green light to indicate that the current lighting environment is suitable for the usage scenario. In contrast, when the first processor 13 determines that the illuminance value sensed by the light sensing element 11 is higher than the upper limit value or less than the lower limit value, the indicator 14 can be controlled to emit red light, indicating that the current lighting environment is not suitable for the usage scenario.

It should be noted that each time the user selects a specific use context, the optical information upper and lower limits corresponding thereto can be transmitted and "stored" in the first through the first and second wireless transceivers 15, 24. The memory 12 has the advantage that the light sensing device 10 can directly access the upper and lower limits corresponding to the use situation as a basis for judging before the user changes the other use scenarios again, and the smart mobile device The light sensing device 10 can operate independently and emit corresponding indication signals without being placed in the vicinity of the light sensing device 10 or continuously maintaining wireless communication.

In the preferred embodiment, the working mode selectable by the user is not limited to the detecting mode. For example, in FIG. 4, the human interface 21 displays a control panel including a plurality of operating modes for the user to switch between these operating modes, including but not limited to the detection mode 217, the battery state 218, and the illumination. In mode 219 and night illumination mode 220, the smart light sensing system will have different performance after the user selects different working modes.

For example, if the user clicks the "battery status" option, the first processor 13 sequentially transmits and stores the remaining battery power signal of the battery through the first wireless transceiver 15 and the second wireless transceiver 16 to the second memory 22 . Then, the second processor 23 can display the remaining power signal to the human machine interface 21.

In the case where the user needs more illumination light, the user can click the "lighting mode" option, and the second processor 23 sequentially transmits an illumination signal to the light via the second wireless transceiver 24 and the first wireless transceiver 15. The device 10 is sensed to cause the indicator 14 to continue to illuminate.

If the light sensing component 11 is used to sense the illuminance of the surrounding environment, the user may also select the "night lighting mode" option. At this time, the second processor 23 sequentially transmits and receives via the second wireless transceiver 24 and the first wireless transceiver. The device 15 transmits a night illumination control signal to the first processor 14, and then the first processor 14 determines whether the light sensing signal (ie, the illuminance value) sensed by the light sensing component 11 is smaller than the nighttime stored in the first memory 12. The illumination activation value (for example, 15 lux), and if so, the first processor 14 issues a control signal to control the indicator 14 to emit light, thereby realizing the function of actively providing night illumination.

In addition, referring to FIG. 5, in this embodiment, the human interface 21 can also be used by the user to select different user identifications 221, such as adults, seniors, and children, and the second memory 22 carries corresponding users. The weighting parameter for identification, for example, the weighting parameter corresponding to "adult" may be 1, the weighting parameter corresponding to "elder" may be 1.3, and the weighting parameter corresponding to "child" may be 0.8. When the human interface 21 is in the detection mode and the user selects a specific user identification, the second processor 22 multiplies at least one of the upper and lower optical information corresponding to the usage context selected by the user. The weighting parameter corresponding to the user selected by the user is identified, and the weighted optical information upper and lower limits are sequentially transmitted through the second wireless transceiver 24 and the first wireless transceiver 15 and stored in the first memory. The first processor 13 compares the light sensing signal sensed by the light sensing component 11 with at least one of the weighted optical information stored in the first memory 12 and the lower limit value, and is based on The comparison result control indicator 14 issues a corresponding indication signal.

Taking "elderly" as an example, when the user selects "elderly" and the user recognizes and selects the use situation of "home watching TV", the second processor 23 will correspond to the optical information corresponding to "home watching TV". (for example, illuminance) The lower limit value 150 lux is multiplied by the weighting parameter 1.3 corresponding to the "old person" identification, and the weighted lower illuminance lower limit value is 195 lux; similarly, the second processor 23 can also correspond The illuminance upper limit value 300 lux of "home TV" is multiplied by the weighting parameter 1.3, and the illuminance upper limit value 390 lux suitable for the "elderly person" is obtained, and the weighted upper and lower illuminance values are passed through the second wireless transceiver 24 and The first wireless transceiver 15 transmits and stores in the first memory 12, so that the first processor 13 can perform comparison according to this to control the indicator 14 to issue a corresponding indication signal.

In other possible implementation manners, the user identification selection method may be input age, gender or other identification information, and the second processor 23 may identify the corresponding user according to the entered age, gender and the like.

Referring to FIG. 6, in addition to illuminance, the intelligent light sensing system of the present invention can also be applied to sensing technology related to color temperature, and its working mode is similar to the foregoing description. In other possible embodiments, the light sensing device can also be internally built with a light sensing component that can sense the illuminance and a light sensing component that can be used to sense the color temperature, and can also be applied to both the illuminance and the color temperature.
