Description

Synchronous control method and system for lighting equipment

Technical Field

The application relates to the field of smart home, in particular to a synchronous control method and system for lighting equipment.

Background

In the field of intelligent lighting, various scene modes such as synchronous turning-on, synchronous color changing and synchronous color temperature adjusting can be realized in a scene through the control (such as adjusting brightness, color temperature and color) of a plurality of lighting devices at the same time. However, since it is not possible to ensure that the trigger timings of the respective devices are the same, there are problems such as inconsistency in lighting change time and confusion in change in the above-described scene mode.

In the related art, a common solution to the above problem is as follows:

1. a unified cloud is adopted to issue control instructions at regular time, and the cloud is used as a synchronous control center; however, for some purely localized full-house intelligent lighting environments, the method cannot be implemented because the whole environment does not depend on a cloud or even does not have a cloud service.

2. A mobile phone client is adopted to issue control instructions at regular time, and the mobile phone is used as a synchronous control center. The method needs the mobile phone to be online at any time, and is poor in convenience.

In addition, because the two methods both need to send instructions at the control end at regular time, the overall effect of synchronous control is poor due to the objective network delay.

At present, no effective solution is provided for the problem of low accuracy of synchronous control of the lighting equipment.

The synchronous control method for the lighting devices provided in the embodiment of the present application can be applied to the application environment shown in fig. 1, where fig. 1 is an application environment schematic diagram of the synchronous control method for the lighting devices according to the embodiment of the present application, and as shown in fig. 1, the terminal 10 and the lighting device 11 are disposed in an intelligent illumination scene, such as an intelligent home and an intelligent exhibition hall.

When the control instructions are executed by the plurality of lighting apparatuses 11 synchronously, scene patterns such as synchronous turning on, synchronous color adjustment, and synchronous color temperature adjustment can be presented in the smart lighting scene. It should be noted that the terminal 10 in the present embodiment may be, but is not limited to, a personal computer, a notebook computer, a smart phone, a tablet computer, and a portable wearable device, and the lighting device 11 includes, but is not limited to, a wall lamp, a desk lamp, a floor lamp, a bedside lamp, and the like.

An embodiment of the present application provides a synchronous control method for a lighting device, and fig. 2 is a flowchart of the synchronous control method for the lighting device according to the embodiment of the present application, and as shown in fig. 2, the flowchart includes the following steps:

s201, a terminal sends a control command to an illumination lamp group in a broadcasting mode, wherein the illumination lamp group comprises a plurality of illumination devices, and the illumination devices share the same input alternating current;

in this embodiment, the control instruction is sent in a broadcast manner, so as to achieve synchronization of sending the control instruction to the lighting device. Since the topology structure of the broadcast mode is a mesh type, which is different from a star type structure, in a well-defined communication domain, the command output by the terminal can be forwarded by each device without being limited by the distance between the lighting device and the terminal.

S202, the lighting equipment obtains an alternating current clock from input alternating current through an internal clock circuit;

the alternating current clock can convert an alternating current signal into a clock pulse signal, and the clock pulse signal is applied to links such as timing and counting.

And S203, the lighting device executes a control command according to the tick of the alternating current clock.

It should be noted that when the clock pulse signal decreases to a value of 0, a clock interrupt, i.e., a clock tick (clock tick) is generated on the clock. When the lighting apparatus executes the control instruction, the hardware section in the lighting apparatus executes one action in the control instruction depending on the tick, that is, once per tick of the ac clock.

Since the frequency of the alternating current is generally 50Hz in daily life, the alternating current ticking time can be determined to be 20ms according to the relationship between the period and the frequency. Due to the persistence of vision of human eyes, the range is 0.1-0.4S, the time of once alternating current ticking is 20ms, and the range is far less than the minimum value of the persistence of vision of human eyes, so that the lighting equipment executes actions according to the ticking beat of the alternating current clock and does not generate abnormal interference on synchronous control.

Through the steps S201 to S203, compared with a method for realizing synchronous control by regularly sending a control instruction through a cloud or a terminal in the related art, in the embodiment of the application, synchronization of sending the control instruction to the lighting device is realized at the control end in a broadcast manner; on the other hand, on the device side, synchronization of control instruction execution is achieved by an alternating current clock obtained based on alternating current. Since the execution of the control command depends on the ac clock, and the lighting devices are powered by the same input ac, the initial time and the step rhythm of the command executed by the lighting devices are consistent, and correspondingly, the action execution of the lighting devices is also synchronous.

Compared with the prior art that synchronization is realized by regularly sending control instructions through a cloud terminal or a field terminal, the embodiment realizes synchronization on the equipment side, so that poor synchronization control effect caused by network delay can be avoided, and more accurate synchronization control effect can be realized. In addition, in the embodiment of the application, the control instruction can be directly sent to the lighting equipment through the terminal in the target scene, so that the method is suitable for a purely local lighting environment and has a wide application range; furthermore, the terminal realizes synchronous control by the equipment side after sending the control command, the terminal is not required to be online at any time, the convenience of personnel is greatly improved, and the resource cost is reduced.

It should be noted that before the terminal sends the control command to the lighting lamp set in a broadcast manner, the terminal needs to establish a connection with the lighting lamp set, where the connection establishment manner includes, but is not limited to, Wi-Fi, a one-key distribution network, an AP distribution network, and a bluetooth peer-to-peer. Optionally, in this embodiment, the terminal and the lighting device are paired through a bluetooth communication protocol, and the pairing mode is independent of a gateway or a cloud, and is simpler and more reliable. Therefore, the intelligent lighting scene in the embodiment can maintain normal work of linkage of various service functions and scenes under the condition of no gateway or cloud support.

Further, after the terminal is matched with the lighting device, a control instruction needs to be generated through the terminal. In the embodiment, an application program in the terminal receives an external interaction signal from an external environment, and generates a control instruction according to the external interaction signal. The external interaction signal can be a touch screen of a manually-used terminal or an external product such as a mouse and a key, and is generated through interaction actions such as clicking and sliding; it can also be generated by machine simulation in an automated fashion.

Furthermore, a self-defined control instruction is generated according to the external interaction signal, and rich illumination effects can be flexibly generated in an intelligent lighting scene; in some embodiments, fig. 3 is a flowchart of generating a control instruction according to an external interaction signal according to an embodiment of the present application, and as shown in fig. 3, the flowchart includes the following steps:

s301, creating a lighting lamp group in an application program according to an external interaction signal, and adding lighting equipment in the lighting lamp group;

in this embodiment, all lighting devices in a scene may be added to each lighting lamp group, or only some lighting devices may be added. In addition, for one lighting scene, multiple lamp groups may also be created simultaneously. That is, in this embodiment, the user can design the control instruction for multiple groups of lighting devices according to the requirement, and further instruct each lamp group to perform different actions, respectively, thereby generating a richer illumination effect.

S302, defining a contextual model in an application program according to an external interaction signal, and adding an action set in the contextual model, wherein the action set comprises a single action or a cyclic action consisting of a plurality of single actions and is used for indicating the action state and the action time of the lighting equipment;

wherein, this contextual model can be according to the nimble definition of user habit or target scene site conditions, for example, under intelligent house scene, the contextual model that can define has: a bed-up mode, a night-reading mode, a sleep mode, etc.; correspondingly, the specific action sets included in each profile may be: (corridor lamp on, toilet lamp on), (bedside lamp on, all lamps except bedside lamp off), (bedroom all lamps off, atmosphere lamp on warm color temperature mode), and the like.

It should be noted that, what is specifically described above is only a part of the contextual models, and a user may design various types of contextual models according to requirements and hardware support conditions, and the scope of protection of the present application should not be limited to the contextual models.

And S303, associating the lighting lamp group with the contextual model to generate a control command.

After the scene mode is defined in step S202, the light group and the scene mode need to be associated, that is, a certain scene mode is specified to be executed by a certain lighting light group. The specific implementation manner of the association is also realized through an application program of the external interactive information operation terminal.

In some embodiments, the clock circuit is a hardware device disposed in the lighting apparatus, and is configured to obtain an ac clock from ac power, and since each lighting apparatus is powered by the same input ac power, an initial value and a tick of the clock obtained based on the ac power are consistent, and the ac clock is applied to the control of the apparatus, so that a good synchronization effect can be achieved. The principle that the clock circuit obtains the alternating current clock from the input alternating current is based on half-wave rectification and shaping, and the method comprises the following steps of:

the clock circuit performs half-wave rectification on input alternating current to obtain pulsating direct current, wherein the half-wave rectification is a method for keeping half of the alternating current to flow through a diode and other elements and blocking the other half to obtain direct current with sine wave half cycle, the pulsating direct current obtained by the method only has positive half cycle or negative half cycle of the sine wave, and the waveform of the pulsating direct current is shown in FIG. 4;

the pulsating direct current is shaped again to obtain a square wave as shown in fig. 4, and the clock circuit can obtain an alternating current clock at the falling edge or the rising edge of the square wave. The ticking beats of the ac clock are different according to the different frequencies of the input ac. Alternating current as is common in life can obtain an alternating current clock with a tick of 10ms or 20 ms.

finally, the user associates above-mentioned banks 1 with contextual model A through APP and generates control instruction, and the terminal is based on bluetooth communication protocol, sends this control instruction to individual lighting apparatus who contains in the banks 1 through the broadcast mode.

The following steps are executed on the device side:

firstly, a table lamp and a bedside lamp which are contained in a lamp group 1 receive the control command at the same time;

secondly, each lighting device acquires a scene mode A in the control instruction through the internal control firmware, and analyzes an action set of the scene mode A to acquire a string of 'on-red-green-blue-off' cyclic action instructions;

further, each lighting device acquires an alternating current clock from the same input alternating current, and cyclically executes the action command of "on-red-green-blue-off" based on the tick of the alternating current clock;

and finally, generating a scene effect of synchronously changing colors in the intelligent home environment when each device synchronously and circularly executes the action instruction.

The embodiment of the application provides a synchronously-controlled lighting device, which can acquire an alternating current clock from input alternating current through an internal clock circuit after receiving a control instruction sent by a terminal, and execute the control instruction according to a tick clock cycle of the alternating current clock.

The step of the lighting device executing the control instructions comprises: performing half-wave rectification on input alternating current through an internal clock circuit to obtain pulsating direct current, wherein the waveform of the pulsating direct current is the positive half cycle or the negative half cycle of a sine wave; further, a clock circuit shapes the pulsating direct current to obtain a square wave, and the alternating current clock is obtained from the square wave; and finally, acquiring the tick clock of the alternating current clock through internal control firmware, and indicating the LED to execute a control instruction according to the tick clock.
