Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The lighting gateway is a system for intelligently controlling and managing lamps, and a general lighting gateway relays and converts received control signals of a light console to send the control signals to the lamps to control the lamps, but with the improvement of life quality of people, the requirements for lamp management and control modes are higher and higher, for example, for lamps of a whole building, the requirements are that the lamps of the whole building can be integrally controlled in color, brightness and the like of light through the light console, and the requirements are that the lamps of a certain floor or a certain room can be locally controlled in color, brightness and the like of light through an intelligent switch, a sensor, a knob and the like, so that an effective means for flexibly controlling the lamps is required.

In one embodiment, as shown in fig. 1, a luminaire control method is provided, and the method is applied to a lighting gateway, and it should be noted that the embodiment of the present application does not limit the specific type of the lighting gateway. In the embodiment of the application, the method comprises the following steps:

step 101, obtaining a plurality of luminaire control signals, wherein the plurality of luminaire control signals comprise at least one of an overall control signal for luminaires in a target site and a local control signal for luminaires in a local area of the target site.

Specifically, the lighting control signal is a control signal that can be used to control the operating mode of the lighting gateway and thus control the lighting. The lamp control signals of the lamps in a certain place can be divided into two types, wherein one type is an integral control signal, namely the signals of all the lamps in the place can be controlled; one is a local control signal, i.e. a signal that can control a part of the luminaires in the site. For example, for an entire building, a control signal capable of controlling all lamps in the entire building is an overall control signal, and a control signal capable of controlling lamps in a certain room or a certain floor of the building is a local control signal.

Optionally, the lighting gateway may receive a lighting control signal sent by the lighting console and a local controller (e.g., an intelligent switch, a sensor, a knob, etc.), where the control signal sent by the lighting console is an overall control signal, the control signal sent by the local controller is a local control signal, and the lighting gateway may receive the overall control signal sent by the multiple lighting consoles and the local control signal sent by the multiple local controllers at the same time.

Step 102, determining a target lamp control signal from a plurality of lamp control signals according to a preset strategy.

Specifically, the preset strategy may be a strategy for performing sorting processing on the plurality of lamp control signals to find a lamp control signal executed first, where the found lamp control signal executed first is a target lamp control signal, and specifically, the preset strategy may be sorting according to letters included in the lamp control signal, and the lamp control signal with the letters arranged first is the target lamp control signal. For example, the lighting gateway receives 3 lighting fixture control signals, where the letter in the overall control signal sent by the lighting console is F, the letter in the local control signal sent by the intelligent switch is C, and the letter in the local control signal sent by the sensor is D, then the local control signal sent by the intelligent switch is the target lighting fixture control signal.

After the lighting gateway acquires the multiple lamp control signals, the execution sequence of the multiple lamp control signals can be determined through a preset strategy, and the risk that the lamps are damaged possibly due to the fact that the lamps are controlled in a chaotic mode due to the fact that the multiple lamp control signals are executed simultaneously is avoided.

And 103, controlling the lamp to work according to the target lamp control signal.

Specifically, the target lamp control signal includes a signal source identifier capable of uniquely identifying and sending the lamp control signal, and information capable of determining a working mode of the lighting gateway, where the working mode of the lighting gateway includes a direct mode, a play mode, and a record mode, and the modes of the lighting gateway controlling the lamp to work are different in different modes.

Optionally, when the target lamp control signal is an overall control signal sent by the light console, and the mode is a direct mode, the lighting gateway is equivalent to a transfer station, and signals for controlling the color, brightness and the like of the lamp sent by the light console are directly sent to the lamp to achieve the purpose of controlling the lamp to work; when the target lamp control signal is an integral control signal sent by a light console, and the mode is a recording mode, the lighting gateway is equivalent to a memory, stores signals for controlling the color, the brightness and the like of the lamp sent by the light console, and sends the signals to the lamp in a play mode to achieve the purpose of controlling the lamp to work; when the target lamp control signal is a local control signal sent by the intelligent switch, and the mode is a playing mode, the lighting gateway is equivalent to a player, and the stored signals of the color, the brightness and the like of the related lamp are called according to the needs of a user and sent to the lamp so as to achieve the purpose of controlling the lamp to work.

In summary, by obtaining a plurality of lamp control signals, where the plurality of lamp control signals include at least one of an overall control signal for a lamp in a target location and a local control signal for a lamp in a local area of the target location, then determining the target lamp control signal from the plurality of lamp control signals according to a preset strategy, and then controlling the lamp to work according to the target lamp control signal, overall control and local control over the lamp can be achieved, and flexibility of lamp control is improved.

Specifically, the lamp control signal includes priority information, the priority information is used for indicating the priority of the lamp control signal, and belongs to a numerical field, the higher the numerical value is, the higher the priority is, and the lamp control signal with the highest priority is the target lamp control signal. The priority in the lamp control signal is set by a User through a browser in a WEB-UI (WEB User Interface), and the priorities of different signal sources are different.

Optionally, after the lighting gateway obtains the multiple lamp control signals, the priority information is extracted from the multiple lamp control signals, and then the priorities are compared, that is, the magnitudes of the values are compared, and the lamp control signal corresponding to the largest value is used as the target control signal.

Specifically, the lighting device control signal includes mode information for indicating an operation mode of the lighting gateway, and therefore, the target lighting device control signal necessarily includes the mode information, the mode information may be represented by a 16-ary numerical value, and different numerical values represent different operation modes of the lighting gateway, for example: 0x01, 0x11, 0x12, 0x21 respectively represent a direct mode, a single play mode, a loop play mode, and a record mode of the lighting gateway. Other identifiers capable of uniquely determining each operation mode of the lighting gateway, such as letters AA, BB1, BB2, CC, may also be used, and the specific form of the mode information is not limited herein.

Optionally, the target lamp control signal is decoded to obtain mode information, different mode information represents different working modes of the lighting gateway, and different working modes control different modes of the lamp to work. The specific mode of operation controls the operation of the lamp as follows.

To sum up, the lamp control signal includes a signal source identifier, priority information, and mode information, and in addition, parameter information, and a specific data structure diagram of the lamp control signal is shown in fig. 2, it should be noted that a user can set a data structure of the lamp control signal through a WEB-UI according to a need of the user. The parameter information includes different information in different working modes of the lighting gateway, which is shown in the following table.

Mode information	Parameter information	Means of
			0x01	Is free of	Straight-through mode
0x11	Signal mark to be played	Single play mode
			0x12	Identification of signal to be played, cycle number	Circular play mode
0x21	New recording signal identification, recording duration	Recording mode

In one embodiment, controlling the operation of the light fixture according to the mode information includes: if the working mode indicated by the mode information is a play mode, extracting a first data signal identifier from the target lamp control signal; and acquiring a first data signal from the signal storage area according to the first data signal identifier, and controlling the lamp to work according to the first data signal.

Specifically, as shown in fig. 2, the data structure of the target luminaire control signal may be extracted from the parameter information to obtain a first data signal identifier, that is, a signal identifier to be played, and according to the identifier, a first data signal may be retrieved from a signal storage area of the lighting gateway, where the first data signal is a signal capable of controlling the color, brightness, and the like of the luminaire. The signal storage area stores a plurality of data signals, and different data signals have unique identifications. And obtaining playing indication information from the parameter information in the target lamp control signal, wherein the playing indication information may be at least one of playing cycle number and playing duration. And then controlling the time length for outputting the first data signal to the lamp according to the playing time length, and controlling the frequency for outputting the first data signal to the lamp according to the playing cycle frequency to achieve the purpose of controlling the lamp to work.

In one embodiment, the first data record includes a first reference data record and a first changed data record, the first reference data record includes channel values of channels in a target data frame in the first data signal, the first changed data record includes channel values of changed channels in a non-target data frame in the first data signal, the channel values of the changed channels are different from a previous data frame, and each data frame included in the first data signal is sequentially determined according to the first data record, including: and determining a target data frame in the first data signal according to the first reference data record, and sequentially determining non-target data frames in the first data signal according to the first change data record after determining the target data frame of the first data signal.

In particular, the first data signal comprises a plurality of data frames, that is to say the first data signal can be regarded as consisting of a plurality of data frames. The data records for storing the data signals in the signal storage area are stored in a data format as shown in fig. 3, and include signal identifiers, frame numbers, channel numbers and channel values, where the channel values are 8-bit binary numbers, and the meaning of different numerical values is different, for example, 00110010 indicates that the color of the lamp is yellow.

Optionally, all data records stored in the data format of fig. 3 that are consistent with the first data signal identifier may be acquired from the signal storage area according to the first data signal identifier, that is, the first data record is obtained. The first data record can be divided into a first reference data record and a first changed data record, the first reference data record is all data records with a frame number of 1, and the first changed data record is all data records with a frame number different from 1. The channel value of each channel in the first reference data record is a target data frame, and the channel value of each channel corresponding to each frame number in the first conversion data record is a non-target data frame.

Optionally, the data record with the frame number of 1, that is, the first reference data record, is obtained first, each channel value in the first reference data record is stored in the buffer area, then the next frame data record, that is, the data record with the frame number of 2 in the first changed data record is obtained, each channel value in the data record is stored in the buffer area, and so on until all the first data records are stored in the buffer area, or the playing time length is reached. It should be noted that, after each channel value is stored in the buffer area, the content stored in the buffer area may be directly sent to the lamp, or after all the first data records are stored in the buffer area, the content stored in the buffer area may be sequentially sent to the lamp, which is not limited herein.

For example, if the first number of signals has N frame data frames, the 1 st frame data frame is retrieved from the signal storage area, that is, all the data records with the frame number of 1, the channel value of each channel in the data record is stored in the buffer area, then the next frame data frame is retrieved, the channel value of each channel in the retrieved data record is stored in the buffer area, the channel value of each channel which is not retrieved is still maintained in the data record of the previous frame until each channel value in the data record with the frame number of N is stored in the buffer area, and finally the data of the transmission buffer area is sequentially transmitted to the lamp, so that the first data signal is played.

In one embodiment, the method further comprises: acquiring a frame period from a signal storage area according to a first data signal identifier; determining a target time length of an interval required between the steps of determining the data frames in each execution according to the frame period; and according to the target duration, sequentially determining each data frame according to the first data record, and storing the determined data frames into a buffer area after determining the data frames each time.

Specifically, in addition to the data record of the data signal shown in fig. 3, the signal storage area also stores the frame period of the data signal in the data format shown in fig. 4, including the signal identifier, the total number of frames, the frame period, i.e., the playing interval of each data frame. Therefore, before determining each data frame in sequence according to the first data record, it is necessary to identify a frame period for acquiring the first data signal according to the first data signal, and use the frame period as an interval duration for acquiring the data frame each time, that is, after storing the acquired data frame in the buffer area each time, the duration of one frame period is equal, and then perform the step of acquiring the data of the next data frame.

In one embodiment, the size of the storage space of the buffer is consistent with the number of channels in the data frame; storing the determined data frame to a buffer, comprising: and covering the channel value of each channel in the determined data frame with the currently stored channel value in the buffer area.

Specifically, if the data signal is DMX512 data, each frame of data has 512 channels, the buffer may have 512 bytes of storage space, and the channel value of each channel in the data frame acquired each time is written into the channel corresponding to the buffer, and if the channel value of each channel in the data frame is not acquired, the channel value of the channel corresponding to the transmission buffer is the channel value of each channel in the previous data frame.

Specifically, if a user sets a play mode through a WEB-UI to play a plurality of data signals, the lighting gateway acquires a plurality of identifiers of signals to be played from parameter information of a target control lamp control signal, that is, the number of first data signal identifiers is multiple, and under the condition that the frame periods of the first data signals are consistent, channel values of channels in first data records corresponding to the first data signal identifiers acquired from the signal storage area for the nth frame are merged or overlaid to obtain a data frame of the nth frame, and the data frame is sent to a buffer area, where the channel values of different channel numbers are merged, and the channel values of the same channel number are overlaid, and the channel value in the first data record of which first data signal identifier is selected in the overlay processing process is not limited, so that the user can set the data frame by himself/herself. In addition, a plurality of first data signals are fused to obtain new data signals, and diversification of the data signals for controlling the lamp is achieved.

In one embodiment, the second data signal includes a plurality of data frames, and determining the second data record based on the second data signal includes: recording the channel value of each channel in the target data frame in the second data signal as second reference data; taking the channel value of each change channel in the non-target data frame in the second data signal as a second change data record, wherein the channel value of the change channel is different from the channel value of the previous data frame; the second reference data record and the second changed data record are recorded as a second data record.

Specifically, in the recording mode, the received data signal capable of controlling the color, brightness, and the like of the lamp is the second data signal, and the second data signal identifier may be obtained from the parameter information in the target lamp control signal. The second data signal is DMX512 data, which is composed of a plurality of data frames, and is stored in the signal storage area in the data format as shown in fig. 3.

Optionally, first, a target data frame, that is, a first data frame, in the second data signal is obtained, and a first reference data record is generated and stored according to the data format of fig. 3, where the data format includes a signal source identifier, a frame sequence number, a channel number, and a channel value. And then acquiring a non-target data frame in the second data signal, namely a next data frame except the first data frame, comparing the acquired next data frame with the previous data frame channel by channel, only storing the data frame with the same channel number and different channel values as the previous data frame according to the data format of fig. 3, and generating a second change data record. And finally, calculating the frame period of the second data signal according to the recording duration in the parameter information of the target lamp control signal and the total frame number of the acquired second data signal, and storing the second data signal identifier, the total frame number and the frame period in a signal storage area according to the data format shown in fig. 4. In addition, the data is stored according to the mode, the changed channel data can be ensured to be stored, the storage space is saved, and the stored data signals are convenient to combine when being played simultaneously in the playing mode.

Specifically, when the operating mode of the lighting gateway is the direct mode, the second data signal acquired from the light control console is directly sent to the lamp to achieve the purpose of controlling the lamp, that is, in the direct mode, the light control console can directly control the lamp, that is, the effect of scene programming of the lamp by the light control console can be achieved.

Specifically, the overall lighting control device may be a lighting console that may send a plurality of signals to the lighting gateway, the plurality of signals including an initial data signal and a second initial control signal.
