Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses a language control lighting system based on a DMX protocol. Referring to fig. 1, the lighting system includes a lighting controller host, a lamp connected to the lighting controller host, and a wireless microphone in communication connection with the lighting controller host, and the wireless microphone is provided with a voice command switching key.
After the voice command switching key is pressed, the wireless microphone receives and identifies voice signals and wirelessly transmits the voice signals to the light controller host; when the voice command switching key is released, the wireless microphone stops transmitting voice signals to the light controller host.
The wireless microphone transmits the received voice signals to the light controller host in a real-time wireless manner, namely, the voice information received by the wireless microphone can be synchronously transmitted to the light controller host for processing, so that the lamp can respond to the light controller host more quickly, and the lamp can respond to the voice signals quickly to display light.
In this embodiment, the light controller host may support about 100 real-time voice commands.
Referring to fig. 2, the language control lighting system based on the DMX protocol compares the voice signal information with the preset display effect information, so that each lamp or the corresponding lamp can perform corresponding lighting display according to the voice signal, thereby realizing voice intelligent control of the lighting system.
The wireless microphone receives and identifies the voice signal and wirelessly transmits the voice signal to the light controller host so as to acquire the voice control information of the user on the lamp.
The light controller host receives the voice signal, compares the voice signal with an internal preset display effect signal, and acquires a related lamp preset display effect signal from the voice signal.
When the comparison result of the voice signal and the preset display effect signal meets the preset condition, the light controller host outputs the light preset display effect signal corresponding to the voice signal to the lamp, namely, the light controller host converts the voice signal into the preset display effect signal which can be recognized by the lamp to output, and the light effect of the lamp is controlled.
Referring to fig. 3, the specific steps of comparing the light controller host with the internal preset display effect according to the voice signal are as follows:
firstly, a one-to-one mapping relation is established between preset display effects and preset voice information in a light controller host. For example, in the preset voice message of "the ginkgo leaves slowly turn yellow in autumn," the "ginkgo leaves" correspond to a type of lighting equipment, such as a moving head light, "slowly" corresponds to a processing effect of gradual change of lighting, "yellow" corresponds to a color change of lighting to yellow.
After receiving the voice signal information transmitted by the wireless microphone, the light controller host analyzes the voice signal information.
The voice signal information contains control signal information related to a preset display effect, and the control signal information comprises action object information, processing effect information and color change information. For example, in the preset voice message of "in autumn, the ginkgo tree leaves slowly turn yellow", the "ginkgo tree leaves" are the information of the action object, "slowly" are the information of the processing effect, and "yellow" is the information of the color change.
The preset voice information comprises a Chinese command word preset by a non-specific person, and the Chinese command word preset by the non-specific person comprises control signal information related to a preset display effect. The Chinese command words preset by unspecific persons do not limit the user identities of the preset voice information, so that the setting mode of the preset voice information is more flexible, and the popularization of the control mode for controlling the light display effect of the lamp according to the voice information is facilitated.
The preset voice information also comprises sensitive words, and the sensitive words are directly mapped with the preset display effect. For example, the preset display effect mapped to "start at night now" is the turning off of the lamp, and the preset display effect mapped to "end at night" is the turning on of the lamp. The sensitive vocabulary is directly mapped with the preset display effect without extracting control signal information from the voice information, so that the response time of the light controller host is shortened, the corresponding preset display effect signal can be rapidly found according to the voice signal, and the light display is favorably realized by rapidly responding the voice signal by the lamp.
After the voice signal information is analyzed, the light controller host extracts control signal information related to a preset display effect in the voice signal information, namely action object information, processing effect information and color change information, or extracts sensitive words related to the preset display effect in the voice signal information.
And after the control signal information or the sensitive words in the voice signal information are extracted, the lamplight controller host machine enables the control signal information or the sensitive words to be mapped with a preset display effect.
When the control signal information or the sensitive vocabulary in the extracted voice signal information is the same as the preset voice information, the light controller host maps to obtain a preset display effect signal for driving the lamp to display due to the one-to-one mapping correspondence between the preset voice information and the preset display effect, so that the aim of acquiring the related preset display effect signal of the lamp from the voice signal is fulfilled.
The language control lighting system based on the DMX protocol has the following beneficial effects:
1. the language control lighting system based on the DMX protocol can establish a mapping relation according to the voice signal and preset display effect information, so that each lamp or corresponding lamp can perform corresponding lighting display according to the voice signal, the aim of adjusting the lighting effect of the lamp in real time according to an actual scene is achieved, a lighting scene effect interacting with audiences is also formed, the instantaneity and the vividness of the display effect of the lamp are improved, the display effect is vivid and profound, the expressive force and the interactivity of a stage are enhanced, meanwhile, the lighting control mode is flexible, the instant exertion of an operator is facilitated, the effect of controlling the whole on-site lighting system through voice can be realized by slightly exercising the operator, and the voice intelligent control of the lighting system is realized;
2. the preset display effect and the preset voice information establish a one-to-one mapping relation to shorten the response time of the light controller host, so that the corresponding preset display effect signal can be quickly found according to the voice signal, and the light display of the lamp is controlled;
3. the action object information in the control signal information is used for controlling the corresponding lamp to display light, so that the light control is more accurate; the processing effect information and the color change information in the control signal information are used for enabling the display effect of the light to be more diversified;
