Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Referring to FIG. 1, FIG. 1 is a schematic flowchart of an embodiment of the dimming method of the present application, and the dimming method includes:

S110: When receiving the trigger instruction, the dimming device acquires and saves the current ambient brightness value.

Specifically, the dimming device may have the function of collecting ambient brightness values. For example, the dimming device may be integrated with a sensor for collecting ambient brightness values, or it may not have the function of collecting ambient brightness values. The sensor establishes a communication connection to obtain the current ambient brightness value. Among them, when the dimming device itself has the function of collecting the ambient brightness value, the dimming device and the lighting device are installed in the same space, and when the dimming device itself does not have the function of collecting the ambient brightness value, establish communication with the dimming device Connected sensors and lighting are installed in the same space. Hereinafter, for the convenience of description, the dimming device itself has the function of collecting the ambient brightness value for description.

The trigger instruction can be an instruction sent by the user. For example, when the user wants to adjust the brightness value of the lighting device, the user sends a dimming instruction to the dimming device, and the dimming instruction is the trigger instruction, or the trigger instruction is the dimming device. It is automatically generated according to the preset rules. For example, if the user sets the dimming to be performed every half hour, the dimming device will generate a trigger instruction every half hour.

S120: Determine whether the brightness difference between the current ambient brightness value and the target brightness value is within a preset range.

Wherein, if the determination result is yes, the process ends, that is, step S180 is entered, and if the determination result is no, then step S130 is entered.

Specifically, the target brightness value may be carried by the trigger instruction, or may be preset and stored in the dimming device, which is not limited herein.

At the same time, if the brightness difference between the current ambient brightness value and the target brightness value is within the preset range, it means that the current ambient brightness value meets the requirements, and when the target brightness value is near, there is no need to dim the lighting equipment, and the process ends directly at this point. .

S130: Acquire the saved dimming value, and determine the dimming direction according to the current ambient brightness value and the target brightness value.

Specifically, the dimming value is the magnitude of the rise or fall of the brightness of the lighting device.

At the same time, if the current ambient brightness value is greater than the target brightness value, the dimming direction is downward, that is, the brightness of the lighting device needs to be reduced. If the current ambient brightness value is less than the target brightness value, the dimming direction is upward, that is, the lighting needs to be increased. The brightness of the device.

S140: Send a dimming instruction to the lighting device that has established a communication connection, where the dimming instruction carries a dimming direction and a dimming value.

Specifically, after receiving the dimming instruction, the lighting device performs dimming according to the dimming instruction.

Among them, the unit of the ambient brightness value and the target brightness value is lux (lux), the brightness value of the lighting device is a level value, and the level value range is 0-255, representing 0-100% brightness. That is, the unit of the ambient brightness value is different from the unit of the lighting device brightness value. It can be understood that the unit of the dimming value is the same as the unit of the brightness value of the lighting device, and is different from the unit of the ambient brightness value.

In an application scenario, in order to reduce the entire dimming time, the dimming instruction sent by the dimming device to the lighting device carries a communication identifier that can be recognized by the lighting device.

Specifically, with reference to FIG. 2 and FIG. 3 , the traditional dimming method in the prior art is that the lighting device reports the current ambient brightness value to the gateway, and then the gateway reports it to the cloud, and then the cloud according to the value set by the user (that is, the target If the absolute value of the difference between the two is found to exceed the preset value, the dimming command will be sent to the gateway, and the gateway will then forward it to the lighting device. This process has a long link and is not conducive to reducing the dimming time.

In this embodiment, the dimming device and the lighting device use the Zigbee (Zifeng protocol, which allows devices to exchange data through groups) group communication mode for communication, and the dimming device and the lighting device pre-establish a Group, that is, the dimming device and the lighting device share a communication identifier, and then in the process of dimming, the dimming device sends a dimming command to the lighting device through multicast, that is, the dimming command sent by the dimming device carries There is a shared communication identifier, and then the lighting device performs authentication after receiving the dimming command, and adjusts the brightness corresponding to the dimming command after the authentication is successful. It can be seen from Figure 2 and Figure 3 that in this embodiment, no need When the gateway relays and forwards data, its communication link can be shortened compared to the communication link in the prior art, so that the dimming delay caused by the long data link can be avoided, and the dimming efficiency can be improved.

S150: After the preset time of sending the dimming command, obtain the current ambient brightness value.

Specifically, after the preset time for the dimming device to send the dimming instruction, it is determined that the lighting device has performed brightness adjustment according to the dimming instruction, and the current ambient brightness value obtained at this time is the brightness of the current environment after the lighting device performs the brightness adjustment. value.

S160: Calculate the brightness difference between the current ambient brightness value and the stored ambient brightness value, and update the stored dimming value according to the brightness difference value.

Specifically, the saved ambient brightness value is the ambient brightness value before dimming, so it can be understood that the brightness difference between the current ambient brightness value and the saved ambient brightness value indicates that the lighting device is performing brightness adjustment according to the dimming instruction After that, the change value of the ambient brightness, that is, the brightness difference value is the feedback to the dimming value carried by the dimming command, reflecting the dimming effect, and then the saved dimming value is updated according to the brightness difference value, so that the next sent dimming value The dimming value carried by the dimming command is the updated dimming value, that is, the next dimming effect is adjusted, so that the dimming time can be shortened and the dimming effect can be improved.

It should be noted that, after the dimming device receives the trigger instruction, the dimming value carried in the dimming command sent to the lighting device for the first time is preset and stored in the dimming device.

Specifically, the relationship between the current ambient brightness value and the brightness difference value of the saved ambient brightness value and the dimming value is affected by the relative position between the sensor (used to collect the ambient brightness value) and the lighting device, and the ambient light and other factors. Influence, that is, with the relative position between the sensor and the lighting device and the change of the surrounding environment, the brightness difference between the current ambient brightness value and the saved ambient brightness value (the result of the change of the ambient brightness value) and the dimming value The relationship between them is not fixed, so the dimming value carried by the dimming command sent to the lighting device for the first time is preset.

In an application scenario, the step of updating the stored dimming value according to the brightness difference value includes: if the absolute value of the brightness difference value is smaller than the adjustment step, increasing the stored dimming value; if the absolute value of the brightness difference value is equal to Adjust the step, keep the saved dimming value unchanged; if the absolute value of the brightness difference is greater than the adjustment step, reduce the saved dimming value.

Specifically, the adjustment step represents the change value of the expected ambient brightness each time the lighting device adjusts the brightness according to the dimming instruction. Wherein, when increasing or decreasing the dimming value, a fixed value can be increased or decreased.

Wherein, when the trigger instruction is received, the absolute value of the brightness difference between the current ambient brightness value and the target brightness value is calculated; the adjustment step is determined according to the absolute value of the brightness difference.

The step of determining the adjustment step according to the absolute value of the brightness difference value includes: calculating the product of the absolute value of the brightness difference value and the acquired inverse of the dimming time; and using the product as the adjustment step.

Specifically, the dimming time is input by the user, and the adjustment step is Det=|(T_V-S_V)|/T, where T_V represents the current ambient brightness value obtained when the trigger command is received, S_V represents the target brightness value, and T Indicates the dimming time.

In other application scenarios, the calculation formula for adjusting the step can also be: Det=|(T_V-S_V)|/N, where T_V represents the current ambient brightness value obtained when the trigger command is received, and S_V represents the target brightness value, N represents the number of dimming times, and similarly, the number of dimming times N can also be input by the user.

In another application scenario, the step of updating the stored dimming value according to the brightness difference value includes: if the absolute value of the brightness difference value is smaller than the first value, superimposing the stored dimming value and the first adjustment value, and using The stored dimming value is updated with the superimposed result; if the absolute value of the luminance difference is not less than the first value but less than the second value, the saved dimming value and the second adjustment value are superimposed, and updated with the superimposed result The saved dimming value, where the first value and the second value are both smaller than the adjustment step, the first value is smaller than the second value, the first adjustment value is greater than the second adjustment value, and the first adjustment value and the second adjustment value are are greater than zero; if the absolute value of the brightness difference is not less than the second value but less than or equal to the adjustment step, keep the saved dimming value unchanged; if the absolute value of the brightness difference is greater than the adjustment step, reduce the saving dimming value.

Wherein, the first value is one third of the adjustment step, the second value is two thirds of the adjustment step, or the first value is one quarter of the adjustment step, and the second value is the adjustment step 3/4 of , as long as the first value and the second value are both smaller than the adjustment step, and the first value is smaller than the second value, no specific limitation is made here. For the convenience of description, the first value is taken as one-third of the adjustment step, and the second value is taken as two-thirds of the adjustment step.

Specifically, when the absolute value of the luminance difference value is less than one third of Det, it means that the intensity of the dimming value is insufficient, and the dimming value is set to A1=A1+B1 (A1 is the dimming value, B1 is the first adjustment value, The dimming value to be saved is superimposed with the first adjustment value, and the dimming value is updated with the superimposed result), when the absolute value of the brightness difference value is greater than or equal to one-third of Det but less than two-thirds of Det , indicating that although the dimming has an effect, it fails to achieve the expected effect. Set the dimming value A1=A1+B2 (B2 is the second adjustment value, and the saved dimming value and the second adjustment value are superimposed, and the superimposed value is used. The result updates the dimming value), when the absolute value of the brightness difference value is greater than or equal to two-thirds of Det but less than or equal to Det, it means that the dimming effect is better, set A1=A1 (that is, keep the dimming value unchanged) , when the absolute value of the brightness difference is greater than the adjustment step, it means that the dimming effect is too strong, set A1=A1-B3 (B3 is the third adjustment value, the third adjustment value is greater than zero, that is, reduce the saved dimming value ).

In an application scenario, after superimposing the saved dimming value and the first adjustment value, and updating the saved dimming value with the superimposed result, the method further includes: judging that the saved dimming value is superimposed with the first adjustment value. Whether the result of dimming is less than the dimming threshold; if the judgment result is yes, the saved dimming value is updated with the superimposed result; if the judgment result is no, a prompt message is issued.

Specifically, if the result of the superposition of the saved dimming value and the first adjustment value is greater than or equal to the dimming threshold, it means that the superimposed result has reached the upper limit of dimming, and the lighting equipment or sensor may be installed incorrectly at this time. , or there is abnormal light source interference, etc., the user will be reminded.

The above has described in detail how to update the saved dimming value. Next, referring to FIG. 1 again, the steps after step S160 will be described in detail.

S170: Update the saved ambient brightness value with the current ambient brightness value.

Specifically, the current ambient brightness value is saved so that the dimming value can be updated next time.

Then, after performing step S170, return to performing step S120.

S180: End the process.

It can be seen from the above that the dimming method in this embodiment will update the dimming value according to the dimming result after dimming the lighting device, that is, update the dimming value according to the feedback result, and the dimming value is not static At the same time, the dimming value does not need to be set according to the change result of the ambient brightness value, so there is no requirement for the relative position and environment between the sensor that collects the ambient brightness value and the lighting device, that is, the dimming method in this application not only It can shorten the dimming time, improve the dimming effect, and can be applied to any application scenarios.

At the same time, the lighting device in this embodiment can also communicate with a remote terminal such as a mobile phone and a computer, and the user can control the on and off, brightness, color temperature, etc. of the lighting device through the remote terminal.
