Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Fig. 1 is a flowchart illustrating a method for synchronizing states of lighting devices according to an embodiment of the present invention. As shown in fig. 1, the method for synchronizing the states of the lighting devices according to the embodiment of the present invention includes the following steps:

step 101, acquiring characteristics of an alternating current signal according to an externally input power supply, using the characteristics as a pulse signal corresponding to each lighting device to be state-synchronized, enabling the pulse signals corresponding to each lighting device to be state-synchronized to be the same, and using a half period of the pulse signal as a unit time base for timing.

As an example, each lighting device to be state-synchronized is connected to a power grid, and an alternating-current voltage output by the power grid is subjected to voltage division processing through a resistor connected in series, so as to obtain a pulse signal corresponding to each lighting device to be state-synchronized.

As a specific embodiment, as shown in fig. 2, each lighting device reduces a 120V/220V alternating current signal input by a mains supply into a 3-5V voltage pulse signal that can be recognized by an MCU through a first resistor and a second resistor, and due to the consistency of the power grid alternating current signals, corresponding pulse signals acquired by each lighting device to be state-synchronized are the same.

It should be noted that each lighting device to be state-synchronized needs to be connected to the same power grid, for example, there are 10 lighting devices to be state-synchronized in total, and the 10 lighting devices to be state-synchronized may be plugged into the same socket and connected to the power grid, so as to ensure that the ac signals received by the 10 lighting devices to be state-synchronized are the same.

Step 102, when the signal to be synchronized in the mode is received, calculating the number of periodic pulses corresponding to the functional mode according to the periodic time of the functional mode corresponding to the signal to be synchronized in the mode and the pulse signal.

It should be noted that, the infrared remote controller may simultaneously send the signal to be synchronized in the corresponding mode to each lighting apparatus to be state-synchronized.

As an example, the corresponding half period time is obtained according to the pulse signal, and is used as a unit time base for timing, and the unit time base is uniquely corresponding to the frequency of the external alternating current signal; according to the unit time base number corresponding to the pulse signal, the number of periodic pulses corresponding to the period time of the functional mode corresponding to the signal to be synchronized in each mode is calculated and set in advance; when a signal to be synchronized in a mode is received, dividing the cycle time of a functional mode corresponding to the signal to be synchronized in the mode by a unit time base number of timing corresponding to the pulse signal to obtain the number of cycle pulses required by the cycle time of the functional mode.

That is, the cycle time of the functional mode corresponding to the signal to be synchronized in each mode is set in advance in the MCU, for example, there are 4 modes in total, the cycle time corresponding to the first mode is 4S, the cycle time corresponding to the second mode is 6S, the cycle time corresponding to the third mode is 10S, and the cycle time corresponding to the fourth mode is 0.5S; if the alternating current signal accessed by each lighting device to be state-synchronized is 220V/50HZ, the frequency corresponding to the half-cycle time is 100HZ, and if the alternating current signal accessed by each lighting device to be state-synchronized is 120V/60HZ, the frequency corresponding to the half-cycle time is 120 HZ; assuming that the MCU receives the signal to be synchronized in the mode sent by the infrared remote controller in the third mode and waits for the synchronizationThe ac signal accessed by each lighting device with synchronous state is 220V/50HZ, and the number of the periodic pulses corresponding to the functional mode obtained by the MCU through calculation is:

it should be noted that, according to the periodic characteristics of the ac signal, the synchronization accuracy can be improved by using the half period as the time base of the timing; in addition, when the preset cycle time of the functional mode corresponding to the signal to be synchronized in each mode is set, the state synchronization of a plurality of devices can be realized without any error as long as the number of the calculated cycle pulses corresponding to the functional mode is a positive integer; the respective signal diagrams of a specific lighting device are shown in fig. 3.

And 103, clearing the cache for calculating the number of the periodic pulses, and restarting cycle counting according to the number of the periodic pulses corresponding to the functional mode so as to control each lighting device to be state-synchronized to perform state synchronization in the functional mode according to the signals to be synchronized in the mode.

As an example, the buffer variable used to count the number of periodic pulses is cleared when a signal that the pattern is to be synchronized is received.

That is, each time the power is turned on again or a signal to be synchronized in the mode is received, the buffer for calculating the number of the periodic pulses is cleared, so that each lighting device to be synchronized in the state is at the same starting point when receiving the signal to be synchronized in the mode, after the signal to be synchronized in the mode is received, the device continuously accumulates the buffer variables for calculating the number of the periodic pulses according to the pulse rising edge and the pulse falling edge of the pulse signal, and when the buffer variables for calculating the number of the periodic pulses in the device connected to the same power grid are accumulated to be equal to the number of the periodic pulses corresponding to the functional mode, the buffer variables for calculating the number of the periodic pulses are automatically cleared and accumulated again, and the cycle is continuously performed. The lighting device state exhibits a corresponding state defined by the corresponding mode synchronization signal during the period of accumulation of the buffered variables of the number of periodic pulses, which results in a visual effect of synchronization of the plurality of devices. Therefore, the consistency of state synchronization is kept, and the problem of periodic state asynchronism caused by crystal oscillator deviation in the MCU is solved.

In summary, according to the state synchronization method for the lighting devices in the embodiments of the present invention, firstly, the characteristics of the alternating current signal are obtained according to the externally input power source, and the obtained characteristics are used as the pulse signal corresponding to each lighting device to be state-synchronized, so that the pulse signals corresponding to each lighting device to be state-synchronized are the same, and the half period of the pulse signal is used as the unit time base for timing; then when receiving the signal to be synchronized, calculating the number of periodic pulses corresponding to the functional mode according to the periodic time of the functional mode corresponding to the signal to be synchronized and the pulse signal; and then, clearing the cache for calculating the number of the periodic pulses, and restarting cycle counting according to the number of the periodic pulses corresponding to the functional mode so as to control each lighting device to be state-synchronized to perform state synchronization in the functional mode according to the signals to be synchronized in the mode.

In addition, an embodiment of the present invention further provides a computer-readable storage medium, on which a state synchronization program of a lighting apparatus is stored, which, when executed by a processor, implements the state synchronization method of the lighting apparatus as described above.

According to the computer-readable storage medium of the embodiment of the invention, by storing the state synchronization program of the lighting device, when the state synchronization program of the lighting device is executed by the processor, the state synchronization method of the lighting device is realized, so that the state synchronization effect can be improved on the premise of low cost and high reliability.

Fig. 4 is a block diagram illustrating a state synchronization apparatus of a lighting device according to an embodiment of the present invention. As shown in fig. 4, the state synchronization apparatus of the lighting device includes an acquisition module 201, a calculation module 202, and a state synchronization module 203.

The acquisition module 201 is configured to acquire characteristics of an alternating current signal according to an externally input power source, and use the characteristics as a pulse signal corresponding to each lighting device to be state-synchronized, so that the pulse signals corresponding to each lighting device to be state-synchronized are the same, and a half period of the pulse signal is used as a unit time base for timing; a calculating module 202, configured to calculate, when a signal to be synchronized in a mode is received, the number of periodic pulses corresponding to a functional mode according to the periodic time of the functional mode corresponding to the signal to be synchronized in the mode and the pulse signal; and the state synchronization module 203 is configured to perform buffer clearing for calculating the number of the periodic pulses, and restart cycle counting according to the number of the periodic pulses corresponding to the functional mode, so as to control each lighting device to be state-synchronized to perform state synchronization in the functional mode according to the signal to be synchronized in the mode.

As an example, each lighting device to be state-synchronized is connected to a power grid, and an alternating-current voltage output by the power grid is subjected to voltage division processing through a resistor connected in series, so as to obtain a pulse signal corresponding to each lighting device to be state-synchronized.

As an example, when a signal to be synchronized in a mode is received, calculating the number of periodic pulses corresponding to a functional mode according to the periodic time of the functional mode corresponding to the signal to be synchronized in the mode and the pulse signal, including: acquiring corresponding half-period time according to the pulse signal, and taking the half-period time as a unit time base for timing, wherein the unit time base is uniquely corresponding to the frequency of the pulse signal; according to the unit time base number corresponding to the pulse signal, the number of periodic pulses corresponding to the period time of the functional mode corresponding to the signal to be synchronized in each mode is calculated and set in advance; when a signal to be synchronized in a mode is received, dividing the cycle time of the functional mode corresponding to the signal to be synchronized in the mode by the unit time base of the timing corresponding to the pulse signal to obtain the number of the cycle pulses required by the cycle time of the functional mode.

As an example, the preset cycle time of the functional mode corresponding to the signal to be synchronized in each mode satisfies that the calculated number of the periodic pulses corresponding to the functional mode is a positive integer, that is, the cycle time of the mode and the unit time base are in a positive integral relationship.

As an example, the buffer variable used to count the number of periodic pulses is cleared when a signal that the pattern is to be synchronized is received.

As an example, after receiving the signal to be synchronized in the mode, the lighting device calculates the buffer variable of the number of pulses in the period according to the continuous accumulation of the rising edge and the falling edge of the pulse signal.

As an example, when the above-mentioned cache variables for calculating the number of periodic pulses in the longitudinal mode devices connected to the same power grid are accumulated to be equal to the number of periodic pulses corresponding to the functional mode, the cache variables for calculating the number of periodic pulses are automatically cleared and accumulated again, and are continuously cycled.

As an example, the lighting device status exhibits the corresponding status defined by the corresponding mode synchronization signal during the period of accumulation of the buffered variables of the number of periodic pulses, which will result in the visual effect of the synchronization of the plurality of lighting devices described above.

It should be noted that the above explanation on the state synchronization method of the lighting device is also applicable to the state synchronization apparatus of the lighting device in this embodiment, and is not repeated herein.

In summary, according to the state synchronization apparatus for lighting devices in the embodiments of the present invention, the obtaining module obtains characteristics of an alternating current signal according to an externally input power source, and the characteristics are used as pulse signals corresponding to each lighting device to be state-synchronized, so that the pulse signals corresponding to each lighting device to be state-synchronized are the same, a half period of the pulse signals is used as a unit time base for timing, and when the calculating module receives a signal to be mode-synchronized, the calculating module calculates the number of periodic pulses corresponding to a function mode according to a period time of the function mode corresponding to the signal to be mode-synchronized and the pulse signals; clearing the cache for calculating the number of the periodic pulses, and restarting cycle counting according to the number of the periodic pulses corresponding to the functional mode so as to control each lighting device to be state-synchronized to perform state synchronization in the functional mode according to the signals to be synchronized in the mode; therefore, the effect of state synchronization can be improved on the premise of low cost and high reliability.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

It should be noted that in the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word "comprising" does not exclude the presence of elements or steps not listed in a claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The invention may be implemented by means of hardware comprising several distinct elements, and by means of a suitably programmed computer. In the unit claims enumerating several means, several of these means may be embodied by one and the same item of hardware. The usage of the words first, second and third, etcetera do not indicate any ordering. These words may be interpreted as names.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.

In the description of the present invention, it is to be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

In the description herein, references to the description of the term "one embodiment," "some embodiments," "an example," "a specific example," or "some examples," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above should not be understood to necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art within the scope of the present invention.
