In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship. Further, the term "plurality" herein means two or more than two.
It is understood that the methods of the present application can include any of the method embodiments described below as well as any non-conflicting combinations of the method embodiments described below.
It is understood that the voice broadcasting method in the present application can be executed by a voice processing device, and the voice processing device can be any device with processing capability, such as a tablet computer, a mobile phone, a computer, and the like, and the voice processing device can also be simply referred to as a device. The speech processing device may be a device capable of connecting to and communicating with the server, or the speech processing device may be the same device as the server.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a voice broadcasting method according to an embodiment of the present application.
The method comprises the following steps:
step S110: and acquiring first broadcast data.
It should be noted that, the image data server capable of acquiring the target scene through the scene information acquisition device may determine whether an alarm event exists in the target scene based on the image data, and when the alarm event exists, it is necessary to prompt that the alarm event exists through voice broadcast. The first broadcast data is generated in response to the target scene existing alarm event.
It can be understood that under the condition that an alarm event occurs in a target scene, voice broadcasting is required, so that people in the target scene are reminded of risks. For example, the target scene is an escalator, and when a falling event occurs at the escalator, voice broadcasting is required to prompt people at the escalator to have the falling alarm event. The server can be used for judging whether an alarm event exists in a target scene or not, but the server cannot perform voice broadcast when the alarm event occurs. In some cases, the target scene has a playing terminal, for example, the escalator itself can play audio or a broadcast speaker box or the like is provided at the escalator. In some cases, the target scene does not have a play terminal, and then a separate play terminal may be provided at the target scene, for example, placing an active speaker next to an escalator. The server may be disposed in other locations, for example, a computer room, and is used for determining whether an alarm event exists at the target scene. The voice processing device provided by the application can be used for connecting a server and receiving broadcast data sent by the server when an alarm event exists so as to control the playing terminal to play audio.
In a specific application scenario, the target scene may be an escalator or an elevator, the scene information acquisition device is a plurality of network cameras, and may acquire image data at the escalator or the elevator, the server may receive the image data sent by the scene information acquisition device and determine whether an alarm event exists in the image data of the target scene, the alarm event may indicate that a risk exists, and an event type of the alarm event that the server determines may be set by a user according to an actual need, for example, the alarm event corresponding to the escalator or the elevator may include a fall alarm, a reverse travel alarm, a retention alarm, a congestion alarm, a wheelchair alarm, a stroller alarm, a large luggage case alarm, and other alarm types, indicating that a safety accident risk exists. In order to perform voice broadcast to prompt that an alarm event exists currently, the server may generate first broadcast data in response to the image data that the alarm event exists, so that the voice processing device may obtain the first broadcast data to perform voice broadcast.
Step S120: a first target audio matched with the first broadcast data is obtained.
It can be understood that, several audios may be pre-stored in the voice processing device, and different audios may be selected to be sent to the play terminal for different alarm events. After the first broadcast data is obtained, the device may obtain, according to the first broadcast data, a first target audio matched with the first broadcast data, where the first target audio is used to prompt an alarm event corresponding to the first broadcast data existing in a target scene.
Step S130: and sending the first target audio to a playing terminal associated with the target scene in a wireless transmission mode.
The playing terminal associated with the target scene can be any device capable of playing audio to the target scene, the number and the position of the playing terminals can be set by a user according to actual needs, and the playing terminal can receive the audio sent by the voice processing device in a wireless transmission mode and play the audio to prompt people existing in the target scene to have alarm events through the audio.
Generally speaking, a wired connection is needed from the server to the voice processing device and then to the broadcasting terminal, but due to the variety of application environments, there are some situations where the server to the broadcasting terminal cannot satisfy the complete wiring condition, for example, the wiring is affected by factors such as too far distance or fire door obstruction, and then the voice broadcast cannot be realized. The voice processing device sends the first target audio to the playing terminal in a wireless transmission mode, so that the position setting of the voice processing device and the playing terminal is not interfered by environmental factors any more, and the setting can be flexibly performed.
In the above scheme, the first target audio corresponding to the first broadcast data is determined by receiving the first broadcast data, and the first target audio is wirelessly transmitted, so that the first target audio is played by the broadcast terminal associated with the wirelessly connected target scene, and the voice broadcast of the alarm event is realized.
In some embodiments, the target scene may not be limited to an escalator or an elevator, but may also be some areas where a risk needs to be prompted, such as an office building, a garden, and the like. The alarm event may indicate that there is a security accident risk or a security leakage risk, and the like, for example, the target scene is a campus, and the alarm event may include an unauthorized entry, and the like.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another embodiment of a voice broadcasting method according to the present application. It is understood that the voice processing device may run a voice broadcast program, where the program includes a service layer, and the relevant steps of the voice processing device in the embodiment of the present application may be executed by the service layer.
The method comprises the following steps:
step S210: and sending a subscription request containing the alarm event information to a server to request the server to respond to the alarm event which is matched with the alarm event information in the target scene, and pushing broadcast data related to the alarm event.
The voice processing device may send a subscription request to the server, where the subscription request includes the alarm event information and is used to request the server to push, to the voice processing device, the announcement data about the alarm event when the alarm event matching the alarm event information exists in the target scene.
The alarm event information includes at least one event type of alarm event, and if the event type of a certain alarm event is the same as one of the event types included in the alarm event information, the alarm event can be considered to be matched with the alarm event information.
It should be noted that the server may determine, based on the image acquired by the scene information acquisition device, whether an alarm event exists in the target scene, the event types of the alarm event that the server can identify may be several, and the event type of the alarm event that the voice processing device subscribes to the server is at least one of the event types of the alarm event that the server can identify.
In a specific application scenario, the target scenario is an escalator, the voice processing device may push a subscription request to the server through a Kafka (distributed publish-subscribe message system) message, where the subscription request includes three types of alarm events, namely, a fall alarm, a reverse alarm and a stroller alarm, so as to request the server to push broadcast data of the alarm event to the voice processing device when the event type of the alarm event occurs is any one of the fall alarm, the reverse alarm and the stroller alarm.
It is to be understood that, in order for the server to send the broadcast data to the voice processing device, the subscription request may further include a receiving address, where the receiving address is an address for receiving the broadcast data related to the alarm event information.
The specific step of sending, by the voice processing device, the subscription request including the alarm event information to the server may be to package the alarm event information and the receiving address to obtain the subscription request, and send the subscription request to the server, where after receiving the subscription request, the server sends, when it is determined that the target scene has an alarm event matching the alarm event information in the subscription request, broadcast data about the alarm event to the receiving address in the subscription request, so that when the target scene has an alarm event matching the alarm event information, the broadcast data about the alarm event is pushed to the voice processing device.
Step S220: and acquiring first broadcast data.
The first broadcast data may include event types to which alarm events exist in the target scene belong, and the voice broadcast device may determine the first target audio that needs to be played based on the event types in the first broadcast data.
In some embodiments, the first report data may include, in addition to the event type of the alarm event, data related to the alarm event, such as image data related to the alarm event, a scene information collection device identification for collecting the image data, and the like. The above-mentioned correlation data can be used in the statistics of alarm events.
Step S230: a first target audio matched with the first broadcast data is obtained.
It can be understood that preset audios corresponding to a plurality of event types can be prestored in the voice processing device, and are used for performing voice broadcast corresponding to different event types, for example, preset audios corresponding to a wheelchair alarm, a stroller alarm, and a large trunk alarm are prestored. Specifically, step S230 may be to select a preset audio matched with the event type in the first broadcast data as the first target audio.
Step S240: and sending the first target audio to a playing terminal associated with the target scene in a wireless transmission mode.
The voice processing device and the playing terminal are connected in a wireless mode through the wireless audio transmitter, so that the voice processing device can send the first target audio to the playing terminal in a wireless transmission mode. In a specific application scenario, the target scenario is an escalator, a sound box is arranged at the escalator to serve as a playing terminal, the voice processing device is a personal computer, the personal computer is connected with a wireless audio transmitter, and the sound box is connected with a wireless audio receiver, so that step S240 can be implemented.
In some embodiments, multiple alarm events may occur simultaneously in the target scene, where multiple alarm events of the same event type may also be included, and for the alarm events of the same event type, the server may perform a merging process on the alarm events of the same type, or may perform separate alarm event processes, where the merging process is described below as an example. In addition, the above multiple alarm events occurring simultaneously may include multiple event types, for example, a case where a stay, a fall, a jam, etc. occur simultaneously on an escalator. Then, in a short time or at almost the same time, the server generates a plurality of first broadcast data corresponding to different types of alarm events, and may send the plurality of first broadcast data to the voice processing device, where each first broadcast data corresponds to an event type of an alarm event, or may also send one first broadcast data including event types of a plurality of alarm events, so that the voice processing device performs voice broadcast on multiple alarm events.
If the server sends a plurality of first broadcast data to the voice processing device, the voice processing device responds to the received first broadcast data, and the device can send first target audio corresponding to each first broadcast data to the playing terminal according to a preset sequence. The preset sequence may be a priority sequence of event types of the alarm event. For example, the first target audio corresponding to the previous event type is preferentially transmitted in the order of a fall alarm, a reverse alarm, a stay alarm, a congestion alarm, a wheelchair alarm, a stroller alarm, a major trunk alarm.
In addition, if the server sends a first broadcast data containing event types of multiple alarm events to the voice processing device, the voice processing device responds that the first broadcast data contain event types of multiple alarm events, and sends a first target audio corresponding to each event type in the first broadcast data to the playing terminal according to a preset sequence.
It can be understood that voice broadcasting of one alarm event may last for a certain time, for example, playing a first target audio may last for 1 minute, multiple alarm events may occur in a target scene successively, a voice processing device may receive multiple pieces of broadcast data successively, each piece of broadcast data is for one alarm event, and if there is no temporal overlap in voice broadcasting of the alarm events that occur successively, that is, when playing a preset audio based on a next piece of broadcast data, a preset audio corresponding to a previous piece of broadcast data has already been played, then the voice processing device may process the preset audio separately, that is, step S220-step S240 may be repeatedly executed. If the device receives new broadcast data and determines a corresponding preset audio during playing of a preset audio corresponding to a certain alarm event, the voice processing device may determine the playing object in multiple ways, for example, the preset audio corresponding to the new broadcast data is used as the audio to be played, and the playing is performed after the playing of the currently played preset audio is completed, or the playing of the current preset audio may be directly stopped, the preset audio corresponding to the new broadcast data is directly played, or the playing object may be determined based on preset rules, for example, the priority of the current alarm event and the priority of the new alarm event, or the playing object may be randomly selected from the currently played preset audio. The following description will be given by taking an example of directly playing a preset audio corresponding to new broadcast data.
Step S250: and acquiring second broadcast data.
It should be noted that after the voice playing device sends the first target audio to the playing terminal associated with the target scene in the wireless transmission manner, the playing terminal receives the first target audio, and receives the second broadcast data during the playing of the first target audio.
And the second broadcast data is generated by the server in response to the alarm event existing in the target scene.
Step S260: and sending a second target audio matched with the second broadcast data to the playing terminal in a wireless transmission mode so that the playing terminal stops playing the first target audio and plays the second target audio.
The playing terminal receives the second target audio data in the process of playing the first target audio, then stops playing the first target audio and plays the second target audio, and therefore the new alarm event corresponding to the second target audio can be broadcasted.
In a specific implementation scene, the target scene is an escalator, two network cameras are used as scene information acquisition equipment to acquire image data at the escalator, and the scene information acquisition equipment is connected with a security network switch of a security monitoring room. The server is connected with the corresponding network switch, the server and the corresponding network switch are deployed in a power distribution room machine room together, and the server is connected with the security network switch through the corresponding network switch, so that the network camera can send the acquired image data of the target scene to the server. In addition, the server is in wired connection with the voice processing device through the corresponding network switch, so that the server can acquire a subscription request and send broadcast data. Escalator department is provided with the active audio amplifier as broadcast terminal, and voice processing equipment connects wireless audio transmitter, and the wireless audio receiver of active audio amplifier connection, both pass through wireless audio transmitter wireless connection to can transmit the target audio frequency, make broadcast terminal can play the target audio frequency and realize voice broadcast. The voice processing device can be arranged at any position capable of being in wireless connection with the playing terminal, the server and the voice processing device can be in wired connection, flexible wiring can be conducted according to the field condition, the positions of the server, the voice processing device and the playing terminal are flexibly arranged, the limitation of the field condition to voice broadcasting is reduced, and the flexibility of the voice broadcasting is improved.
In some embodiments, the server may also be connected to the external network switch through its corresponding network switch, so that data transmission may be performed.
In the above scheme, the first target audio corresponding to the first broadcast data is determined by receiving the first broadcast data, and the first target audio is wirelessly transmitted, so that the first target audio is played by the broadcast terminal associated with the wirelessly connected target scene, and the voice broadcast of the alarm event is realized. In addition, when a plurality of alarm events occur and the alarm event processing occurrence time is coincident, the voice processing equipment can process according to the sequence and the rule preset by the user, so that the voice broadcasting is more flexible.
Referring to fig. 3, fig. 3 is a schematic flowchart of a voice broadcasting method according to another embodiment of the present application, and in this embodiment, a voice processing device and a server are taken as the same device for example.
It is understood that the server includes an event detection module and a voice processing module, and data transmission can be performed between the voice processing module and the event detection module. The event detection module may be configured to determine whether an alarm event exists in a target scene, and the voice processing module may be configured to perform a related operation of voice broadcast based on the alarm event, for example, to perform acquisition of a first target audio matched with first broadcast data and subsequent steps thereof. The playing terminal can be located near the target scene, so that when the playing terminal plays audio, a user in the target scene can hear the voice prompt, and the server can be located within the wireless transmission range of the playing terminal.
Further, the server may further include a message system module, and the message system module may be used for data transmission between the voice processing module and the event detection module. The voice processing module can package the alarm event information and the receiving address to obtain a subscription request, and sends the subscription request to the message system module, and the message system module stores the subscription request after receiving the subscription request, so as to push the broadcast data.
Step S310: an event detection module of the server receives image data obtained by shooting a target scene, responds to the fact that an alarm event exists in the image data, and generates first broadcast data related to the alarm event.
The scene information acquisition equipment can shoot a target scene to obtain image data, and transmits the image data to the event detection module of the server, and the event detection module can process based on the image data to detect whether an alarm event exists in the target scene. And generating first broadcast data regarding the alarm event in the case where the alarm event exists in the image data.
It should be noted that, in some embodiments, the event types of the alarm event that can be detected by the event detection module may include several types, including the event type subscribed by the voice processing module, and may also include other event types beyond the event type subscribed by the voice processing module. The event detection module may detect all detectable event types and generate corresponding broadcast data, where the first broadcast data includes the event types subscribed by the voice processing module. The event detection module can also store the generated broadcast data.
Step S320: and the event detection module pushes the first broadcast data to a voice processing module of the server.
It can be understood that step S110 can be implemented by step S310 and step S320, because the voice processing device and the server are the same device, the event detection module of the server generates the first broadcast data and pushes the first broadcast data to the voice processing module, which means that the voice processing device acquires the first broadcast data, and then can perform subsequent processing based on the first broadcast data.
Specifically, the event detection module can push the generated broadcast data to the message system module through a Kafka message queue "transmission queue", wherein the generated broadcast data also includes the first broadcast data, and after the message system module receives the broadcast data, according to the stored subscription request, it is determined that the event type corresponding to the first broadcast data matches with the subscription request sent by the voice processing module, and the first broadcast data is pushed to the receiving address in the subscription request, so that the first broadcast data is pushed to the voice processing module.
In the above embodiments, the server processes the image data of a certain target scene, the voice processing device broadcasts based on the broadcast data of the target scene, in some embodiments, the server may also receive and process image data corresponding to a plurality of different target scenes separately to generate broadcast data separately, each target scene may correspond to a voice processing module/voice processing device separately, or a plurality of target scenes may correspond to one voice processing module/voice processing device, and if a plurality of voice processing modules/voice processing devices exist, the server may also receive a multi-party subscription request, and the message system module may match the subscription request sent by each voice processing module/voice processing device with the broadcast data sent by the event detection module, and push corresponding broadcast data to the subscriber. The subscriber may be a number of voice processing modules in the server and/or a number of voice processing devices connected to the server.
Step S330: the voice processing module acquires a first target audio matched with the first broadcast data.
Step S340: the voice processing module sends a first target audio to a playing terminal associated with a target scene in a wireless transmission mode.
In the above scheme, the server and the voice processing device can be the same device, so that the device for voice broadcasting is simplified, the device is more flexibly deployed, the first broadcast data are received, the first target audio corresponding to the first broadcast data is determined, and the first target audio is wirelessly transmitted, so that the first target audio is played by the play terminal associated with the wirelessly connected target scene, and the voice broadcasting of the alarm event is realized.
