Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, in an embodiment, a lighting control method is provided, where the lighting control method is applicable to both a terminal and a server, and specifically includes the following steps:
The microwave signal is a signal generated by a microwave sensor based on a microwave induction technology, and is used for detecting whether motion information exists in a target area of the lighting equipment, and a sine wave is generated when the motion signal is detected, wherein the higher the motion speed is, the larger the amplitude of the sine wave is, so that the motion information of the target area can be determined according to the microwave signal. The target area refers to an area which is close to the area where the lighting device is located, and exemplarily, the maximum area which can be radiated by the lighting device can be tested as the target area. The motion information is information indicating whether a person or an object moves in the target area, and is used as a basis for controlling the illumination of the illumination device at the server side.
And 104, acquiring a voltage signal of the target area acquired by an illuminance sensor, acquiring an illuminance coefficient corresponding to the voltage signal, and multiplying the voltage signal by the illuminance coefficient to obtain illuminance information of the target area, wherein the illuminance coefficient is calculated based on a corresponding relation between an actual voltage signal and actual illuminance information.
The voltage information is a voltage signal of the illuminance sensor in the surrounding environment of the lighting device, i.e., the target area, and is used for determining the illuminance information of the target area. The illuminance coefficient is an index reflecting a conversion relationship between the illuminance information and the illuminance signal, and is calculated based on a correspondence relationship between the actual voltage signal and the actual illuminance information.
It should be noted that, because the voltage signal is collected by the single chip microcomputer in the illuminance sensor, and the interval range of the voltage signal value that can be read by the single chip microcomputer is 0 to 3.3V, the illuminance value collected by the corresponding illuminance sensor is 0 to 20Wlux (lux), that is, it is difficult to collect illuminance information of more than 20Wlux by using the illuminance sensor under normal conditions. Therefore, in the present embodiment, two chips, namely, LM2904 and CD4051 are used, wherein the CD4051 chip implements channel selection, and the chip outputs one of pins C0-C7 by controlling three pins ABC. The resistors with different resistance values are connected to the pins C0-C7, voltage signals output by the sensor are weak, the voltage signals are amplified by selecting different resistance values according to the principle of voltage division, corresponding resistors are selected by comparing the voltage signal values, and then different amplifying circuits are controlled, so that the illumination sensor can detect illumination intensity in a larger range.
Furthermore, in the process of calculating the illumination coefficient, a plurality of gears are divided according to the actual value of the illumination information and the actual value of the voltage signal, that is, one voltage signal range corresponds to one illumination information range, that is, one gear, and the gear in which the voltage signal value is located is judged, and then the voltage signal value is collected according to the amplification factor corresponding to the amplification circuit of the current gear. The actual illumination information and the actual voltage signal value are detected for multiple times by the amplifying circuit method, the illumination coefficient of each time is respectively calculated, the average value of each illumination coefficient is used as the illumination coefficient in the embodiment, and understandably, the voltage signal is multiplied by the illumination coefficient to obtain the illumination information of the target area, so that the range of the illumination information is increased, and the accuracy of the illumination information is improved, so that the illumination control can be more accurately performed on the basis of the illumination information.
And 106, controlling the lighting equipment by adopting a preset strategy based on the illumination information and the motion information.
The preset strategy refers to a lighting control circuit of the device in advance, and includes adjusting illumination information of the lighting device, turning off the lighting device and the like. Specifically, the server judges whether a judgment condition corresponding to a preset strategy is reached or not according to the illumination information and the motion information of the target area, and controls the lighting equipment, so that the lighting equipment is intelligently controlled, and dual effects of energy conservation and emission reduction and use of the lighting equipment as required are favorably achieved.
According to the illumination control method, the microwave signal is obtained, and the motion information of the target area of the illumination equipment is obtained based on the microwave signal; acquiring a voltage signal of the target area acquired by an illuminance sensor, acquiring an illuminance coefficient corresponding to the voltage signal, and multiplying the voltage signal by the illuminance coefficient to obtain illuminance information of the target area, wherein the illuminance coefficient is calculated based on a corresponding relation between an actual voltage signal and actual illuminance information; and controlling the lighting equipment by adopting a preset strategy based on the illumination information and the motion information. The illumination control method can realize intelligent control of the illumination equipment, and is beneficial to achieving the dual effects of energy conservation and emission reduction and using the illumination equipment as required.
As shown in fig. 2, in one embodiment, acquiring a microwave signal, and acquiring motion information of a target area of an illumination device based on the microwave signal, includes:
and step 102A, acquiring microwave signals of the target area acquired by the microwave sensor in a periodic sampling mode.
Specifically, by adopting a periodic sampling mode to collect microwave signals, the motion of a human body or an object is continuous, the microwave signals collected by corresponding microwave sensors can generate continuous waveforms, and since the clutter is irregular and discrete, the microwave signals collected by corresponding microwave sensors are sampled at intervals for a plurality of times within a period of time, namely, in a periodic adoption mode, if continuous waveforms generated by the motion exist, the continuous waveforms can be sampled for a plurality of times, the probability of the clutter being sampled continuously is extremely low, exemplarily, the motion is detected every 1 millisecond, when the motion is detected for the first time, the motion is waited for 10 milliseconds, and whether the motion exists is judged by judging the number of times of triggering within 10 milliseconds. Through the method of time-delay multiple detection, clutter collected by the microwave sensor can be effectively filtered out, so that the motion information of the target area can be further processed on the basis of the microwave information.
And step 102B, filtering the microwave signal, and normalizing the microwave signal after the filtering to obtain a microwave waveform.
The filtering process is a data preprocessing process for removing noise, such as a smoothing filtering method, a mean filtering method, or a gaussian filtering method. Normalization refers to the process of analyzing the distribution of useful information in a microwave signal. The microwave waveform is an expression form capable of reflecting the degree of motion of data corresponding to the microwave signal. It can be understood that the microwave waveform is obtained by filtering the microwave signal and normalizing the filtered microwave signal, so that the motion information of the target area is identified by the microwave signal.
And step 102C, judging whether the target area moves according to the amplitude of the microwave waveform, and taking the judgment result as the motion information.
Specifically, the amplitude of the microwave waveform can reflect the movement speed of the object or the human body, so that whether the target area moves or not is judged according to the amplitude of the microwave waveform, and the judgment result is used as movement information, wherein the movement information comprises movement and no movement. Understandably, due to the fact that the microwave information is preprocessed in the steps 102A to 102B, clutter is filtered, the microwave waveform of the microwave signal is determined, and then the motion of the object or the human body can be rapidly and accurately identified according to the microwave information, so that the motion information is prevented from being determined through the camera, and compared with the camera, the cost is reduced, and the efficiency of obtaining the motion information is improved.
In the above embodiment, first, the microwave signal of the target area acquired by the microwave sensor is acquired in a periodic sampling manner; then, filtering the microwave signal, and normalizing the filtered microwave signal to obtain a microwave waveform; and finally, judging whether the target area moves or not according to the amplitude of the microwave waveform, and taking the judgment result as the motion information, thereby improving the efficiency of obtaining the motion information.
As shown in fig. 3, in an embodiment, determining whether the target area has motion according to the amplitude of the microwave waveform, and using the determination result as the motion information includes:
step 102C1, if the amplitude of the microwave waveform is greater than a preset detection threshold, the motion information is motion.
The preset detection threshold is a critical value used for judging whether the amplitude of the microwave waveform moves or not. When the amplitude of the microwave waveform is larger than a preset detection threshold value, a motion signal exists, and therefore the motion information is determined to be motion.
Step 102C2, if the amplitude of the microwave waveform is less than or equal to a preset detection threshold, the motion information is no motion.
Specifically, when the amplitude of the microwave waveform is less than or equal to the preset detection threshold, that is, there is no motion signal, the motion information is determined to be no motion.
By comparing the amplitude of the microwave waveform with the preset detection threshold, the motion information can be quickly determined according to the microwave information.
As shown in fig. 4, in one embodiment, the preset strategy includes adjusting the illuminance of the lighting device;
the controlling the lighting device by adopting a preset strategy based on the illumination information and the motion information includes:
Specifically, when the motion information is no motion, that is, no moving object or human body exists in the target area, at this time, the illuminance of the lighting device is adjusted to 0, that is, the lighting device is turned off, so that an energy-saving effect is achieved, and light pollution is reduced.
And step 106B, if the motion information indicates that motion exists, adjusting the illumination intensity of the lighting equipment according to the illumination information.
Specifically, when the motion information indicates that there is motion, that is, there is a moving object or human body in the target area, the illuminance of the lighting device is adjusted according to the illumination information, so that the lighting device is used as needed, and an effect of intelligently controlling the lighting device is achieved.
In the above embodiment, if the motion information is no motion, the illuminance of the lighting device is adjusted to 0, so that the effect of energy saving is achieved, and light pollution is reduced; if the motion information is motion, the illumination intensity of the lighting equipment is adjusted according to the illumination information, so that the lighting equipment can be used as required, and the effect of intelligently controlling the lighting equipment is achieved.
As shown in fig. 5, in one embodiment, the illuminance information includes first illuminance information of a lighting device of the target area and second illuminance information of a current environment of the target area.
The first illuminance information refers to illuminance information of an illumination device of the target area, and the second illuminance information refers to illumination information of a current environment of the target area.
The adjusting the illuminance of the lighting device according to the illumination information includes:
step 106B1, comparing the first illuminance information with the second illuminance information, and keeping the illuminance of the illuminance device unchanged when the difference between the first illuminance information and the second illuminance information is within a preset illuminance range.
Specifically, the first illuminance information and the second illuminance information are compared, and when a difference value between the first illuminance information and the second illuminance information is within a preset illuminance range, that is, illuminance values of the first illuminance information and the second illuminance information are relatively close to each other, the illuminance of the illuminance device is kept unchanged.
Step 106B2, when the difference is not within the preset illumination range and the first illumination information is greater than the second illumination information, adjusting the illumination of the illumination device to an illumination corresponding to the second illumination information.
Specifically, when the difference is not within the preset illumination range, that is, the difference between the illumination values of the first illumination information and the second illumination information is large, and the first illumination information is greater than the second illumination information, in order to reduce the unnecessary illumination of the lighting apparatus, the illumination of the lighting apparatus is reduced to the illumination corresponding to the second illumination information, so that the illumination of the lighting apparatus is close to the illumination of the current environment, and the energy saving effect is achieved.
Step 106B3, when the difference is not within the preset illumination range and the first illumination information is smaller than the second illumination information, increasing the illumination of the illumination device to the illumination corresponding to the second illumination information.
Specifically, when the difference is not within the preset illumination range, that is, the difference between the illumination values of the first illumination information and the second illumination information is large, and the first illumination information is smaller than the second illumination information, in order to better achieve the illumination effect of the illumination device, the illumination intensity of the illumination device is increased to the illumination intensity corresponding to the second illumination information, so that the illumination intensity of the illumination device is close to the illumination intensity of the current environment, so that the user can use the illumination device better as needed, and the intelligent control of the illumination device is achieved.
The illuminance of the lighting equipment is adjusted according to the illumination information, so that the intelligent degree of the control of the lighting equipment is improved.
In one embodiment, after the controlling the lighting device by using the preset strategy based on the illuminance information and the motion information, the method further includes:
and sending the preset strategy to an explosion-proof detector connected with the lighting equipment in a gateway mode.
The gateway is a network transmission protocol, and is used for transmitting data of the server, namely a preset policy. Specifically, a preset strategy can be sent to the explosion-proof detector connected with the lighting device through the RF433 protocol, so that the explosion-proof detector controls the lighting device according to the preset strategy, and the transmission efficiency and the operation efficiency of the explosion-proof detector are improved.
The process of sending the preset strategy to the explosion-proof detector connected with the lighting equipment in a gateway mode improves transmission efficiency and operation efficiency.

The heartbeat packet is a self-defined command word which is used for regularly informing the self state of the other side between the client side and the server. And the server side judges whether a heartbeat packet exists or not by receiving the gateway instruction.
And 108B, when a heartbeat packet exists, responding to the heartbeat packet to enable the explosion-proof detector to control the lighting equipment according to the preset strategy.
Specifically, when a heartbeat packet exists, the server responds to the heartbeat packet, so that the explosion-proof detector can store a preset strategy, the control on the lighting equipment is realized according to the preset strategy, the gateway pressure is reduced, and the control efficiency on the lighting equipment is improved.
In the above embodiment, if a gateway instruction is received, it is determined whether a heartbeat packet exists in the gateway instruction; and when the heartbeat package exists, responding to the heartbeat package so that the explosion-proof detector controls the lighting equipment according to the preset strategy, thereby reducing the gateway pressure and improving the control efficiency of the lighting equipment.
