[0039] Figure 1It is a schematic structural diagram of a broadcast end provided by an embodiment of the present invention. The broadcast end includes a broadcast module 110, an environment detection module 120, a decision-making module 130, and a communication module 140. The broadcast module 110, the environment detection module 120, and the communication module 140 are respectively connected to the decision-making module 130. Among them, the environment detection module 120 is used to detect the environmental data of the environment where the broadcast end is located and transmit the detected environmental data to the decision-making module 130; the decision-making module 130 determines the environmental data. When the environmental data meets the warning conditions, it transmits the environmental data to the control end through the communication module so that the control end can perform control processing based on the environmental data; the decision-making module 130 also receives the broadcast data sent by the control end through the communication module, determines the environmental state based on the environmental data, determines whether there is a contradiction between the data content of the broadcast data and the environmental state. If so, it updates the broadcast data based on the environmental data and sends the broadcast data to the broadcast module 140; the broadcast module 140 outputs the broadcast data.

[0040] The broadcast system includes a control end set at the back end and a broadcast end set in a public environment. Among them, the broadcast end can be set in a public environment such as indoors or outdoors. The public environment can be such as a park, a museum, a building, etc. The setting position and the number of broadcast ends in the public environment are not limited here.

[0041] There can be multiple broadcast ends set in the public environment, and each broadcast end is respectively communicatively connected to the control end for data transmission.

[0042] In this embodiment, the broadcast end is provided with an environment detection module 120 for detecting the environmental data of the environment where the broadcast end is located. By integrating the environment detection module 120 into the broadcast end, the detection and transmission of environmental data can be realized through the communication connection between the broadcast end and the control end, without separately arranging a set of environmental data transmission system, reducing the equipment layout cost.

[0043] Optionally, the environment detection module 120 includes one or more of the following: a brightness sensor, a noise detection sensor, an electrostatic sensor, a temperature sensor, a humidity sensor, an infrared sensor; correspondingly, the environmental data includes one or more of the following: environmental brightness data, environmental noise data, environmental electrostatic data, environmental temperature data, environmental humidity data, infrared image data.

[0044] Among them, the brightness sensor is used to detect the environmental brightness data of the environment where it is located; the noise detection sensor is used to detect the environmental noise data of the environment where it is located; the temperature sensor is used to detect the environmental temperature data of the environment where it is located; the humidity sensor is used to detect the environmental humidity data of the environment where it is located; the infrared sensor is used to collect the infrared image data of the environment where it is located. It can be understood that the sensors included in the environmental detection module 120 are not limited to the above sensor types. Correspondingly, the detected environmental data is also not limited to the above data types. The types of sensors included in the environmental detection module 120 can be set according to the detection requirements of the environment where it is located, and no limitation is made in this regard. Optionally, an expansion interface is provided in the environmental detection module 120, and the sensors in the environmental detection module 120 can be expanded according to requirements to meet the detection needs.

[0045] In this embodiment, environmental data is collected by at least one sensor in the environmental detection module 120 to implement the collection of environmental data for subsequent determination of the environmental data.

[0046] At least one sensor in the environmental detection module 120 is respectively connected to the decision module 130, and each sensor sends the collected environmental data to the decision module 130. Exemplarily, see Figure 2 , Figure 2 is a schematic diagram of multiple sensors in the environmental detection module and the decision module provided by the embodiment of the present invention. Among them, the sensors in the environmental detection module 120 can collect environmental data in real time, or collect data based on a preset time interval. Among them, multiple sensors can be collected synchronously or asynchronously, and no limitation is made here.

[0047] The decision module 130 respectively determines each type of collected environmental data based on a preset first determination rule. When any type of environmental data meets the warning condition, a warning message is generated, and the warning message and the detected environmental data are transmitted to the decision module through the communication module.

[0048] The decision module 130 can be a processor or a controller, and no limitation is made on the hardware implementation of the decision module 130 here. The decision module 130 receives the environmental data sent by multiple sensors in the environmental detection module 120, and determines the environmental data. When each type of environmental data does not meet the warning condition, the environmental data can be locally stored or discarded; when any type of environmental data meets the warning condition, multiple types of environmental data are sent to the control end for warning processing.

[0049] The decision-making module 130 stores the determination rules for each type of environmental data and determines each type of environmental data separately. Among them, different types of environmental data can be determined in parallel through different threads. Exemplarily, the determination rules for environmental brightness data, environmental noise data, environmental static electricity data, environmental temperature data, and environmental humidity data can include warning thresholds, and the warning thresholds for different types of environmental data are different. Compare the above environmental data with the corresponding warning thresholds, and determine that the warning condition is met when the environmental data exceeds the warning threshold. The determination rule for infrared image data can be to identify the objects included in the infrared image data and the object behaviors of consecutive multiple frames of infrared image data. When the identified object is a warning object and / or the identified object behavior is a warning behavior, it is determined that the warning condition is met. Among them, warning objects include but are not limited to fire, knives, etc., and warning behaviors include but are not limited to damaging public facilities, fighting, etc.

[0050] When the environmental data satisfies the warning condition, the decision-making module 130 sends the collected environmental data to the control terminal so that the control terminal can perform control feedback based on the received environmental data. The decision-making module 130 does not transmit the environmental data that does not satisfy the warning condition, reducing the unnecessary data transmission process and at the same time reducing the space occupied by unnecessary environmental data on the control terminal.

[0051] Optionally, the broadcast terminal further includes a memory for storing environmental data. Specifically, it can store environmental data within a certain time period for querying historical environmental data.

[0052] It can be understood that since the environmental range where a broadcast terminal can collect data is limited, when the control terminal receives the warning information and its environmental data sent by a broadcast terminal, in order to perform accurate control feedback through comprehensive environmental data, it is necessary to obtain the environmental data of other broadcast terminals in the environment where the broadcast terminal is located to improve the comprehensiveness of the environmental data and further improve the accuracy of the control information for the broadcast terminal.

[0053] Optionally, when the environmental data satisfies the warning condition, the decision-making module 130 sends a trigger signal to other broadcast terminals in the environment where it is located so that the other broadcast terminals send environmental data to the control terminal. Among them, different broadcast terminals can be communicatively connected, and a communication connection is established in advance among multiple broadcast terminals in the same environment. When the environmental data collected by any broadcast terminal satisfies the warning condition, the decision-making module 130 generates a trigger signal and sends the trigger signal to other broadcast terminals through the communication module 140 so that the other broadcast terminals send the collected environmental data to the control terminal when they receive the trigger signal.

[0054] Optionally, when the control terminal receives the warning information and environmental data sent by any broadcasting terminal, it determines the associated broadcasting terminals in the same environment based on the location information of the broadcasting terminal. Each broadcasting terminal is provided with a device identifier for uniquely marking the broadcasting terminal. The control terminal stores the corresponding relationship between the device identifier and the location information of the broadcasting terminal. The broadcasting terminal can send environmental information in the form of a message, and the message can also include warning information and the device identifier of the broadcasting terminal. The location information of the broadcasting terminal can be determined through the device identifier. The associated broadcasting terminals of the broadcasting terminal can be other broadcasting terminals within a preset range, or other broadcasting terminals within the same building range, such as other broadcasting terminals within the same square, the same museum, or the same shopping mall, etc.

[0055] The control terminal determines the associated broadcasting terminals according to the location information of each broadcasting terminal and sends a trigger signal to the associated broadcasting terminals. Correspondingly, any associated broadcasting terminal receives the trigger signal sent by the control terminal and sends environmental data to the control terminal.

[0056] When the control terminal does not receive environmental data, it generates broadcast data for each broadcasting terminal according to a preset control strategy and sends the broadcast data to each broadcasting terminal. The broadcasting terminal receives the broadcast data through the communication module 140 and sends it to the decision-making module 130. The preset control strategy can be a playing strategy for audio data. Exemplarily, the preset control strategy can be the corresponding relationship between time information and audio data. The audio data to be played is determined according to the current time information, and the broadcast data is generated based on the audio data to be played. Exemplarily, the preset control strategy can be a playing strategy for audio data. For example, if the audio data is music data, its playing strategy can be loop playing. The preset control strategy can be pre-set or edited according to the playing requirements.

[0057] When the control terminal receives environmental data, it can generate a control strategy according to the environmental data of multiple broadcasting terminals, generate broadcast data for each broadcasting terminal based on the control strategy, and send the broadcast data to each broadcasting terminal. The control strategy can include a crowd evacuation strategy. The control terminal analyzes the environmental data of multiple broadcasting terminals and generates a crowd evacuation strategy when it determines that there is a need for crowd evacuation. The generation method of the crowd evacuation strategy can be to generate a crowd evacuation path according to the map of the environment where the broadcasting terminal is located, and generate path indication broadcast data for each broadcasting terminal according to the location information of the broadcasting terminal and the crowd evacuation path. The path indication broadcast data can include the evacuation direction.

[0058] The control strategy can also include prompt broadcast data. Exemplarily, when the detected environmental noise data exceeds the warning information, broadcast data for prompting to reduce the noise is generated.

[0059] Optionally, the control end further includes sending a prompt message to the management end of the environment where the broadcast end is located, and displaying the prompt message on the management end, so that the management personnel can process it by viewing the prompt message. The management end can be the terminal of the management personnel, such as a mobile phone, etc. Exemplarily, when the management end receives a noise prompt of a certain broadcast end, it can prompt the personnel who generate the noise, etc.

[0060] The decision-making module 130 receives the broadcast data through the communication module 140, and can send the broadcast data to the broadcast module 110, and the broadcast module 110 can output the broadcast data. Among them, the broadcast module can be devices such as speakers and horns.

[0061] Before sending the broadcast data to the broadcast module 110, the decision-making module 130 also determines whether the data content of the broadcast data conflicts with the environmental state of the location. If there is no conflict, the broadcast data is sent to the broadcast module 110 for playback. If there is a conflict, the broadcast data is updated based on the environmental data, and the updated broadcast data is sent to the broadcast module 110 for playback.

[0062] Optionally, when the broadcast data is media data such as music, it is determined that there is no conflict. When the broadcast data is a prompt message, the data content of the broadcast data is identified, and the environmental state of the current environmental data, and whether the data content of the broadcast data conflicts with the environmental state are determined. Exemplarily, when the data content of the broadcast data is to reduce noise, it is determined whether the environmental noise data exceeds the noise threshold. If so, it is determined that the current noise is large and the noise needs to be reduced, which does not conflict with the broadcast data. Exemplarily, when the data content of the broadcast data is to please move to the left exit, it is determined whether the current path and the left exit meet the evacuation conditions. If not, it is determined that there is a conflict with the broadcast data.

[0063] When there is a conflict between the environmental state and the data content of the broadcast data, the broadcast data is updated according to the environmental data. Exemplarily, when the broadcast data is path indication broadcast data and conflicts with the environmental state, the broadcast data can be updated to this path is blocked, etc. The updated broadcast data can be determined according to the environmental data, which is not limited here. Optionally, multiple updated broadcast data of the broadcast data are preset, and when any broadcast data conflicts with the environmental state, the corresponding updated broadcast data of the broadcast data is called.

[0064] In the technical solution of this embodiment, by integrating the environmental detection module into the broadcast end, the broadcast end can send environmental data to the control end through the transmission path between the broadcast end and the control end based on the function of environmental data detection. By setting a decision-making module in the broadcast end to judge the collected environmental data and the broadcast data to be played, the broadcast end adds a decision-making function on the basis of the broadcast function, and can determine whether to transmit to the control end for early warning according to the judgment result of the environmental data, and judge the broadcast data through the environmental data to decide whether to play the broadcast data. This replaces the way of only playing the data transmitted to the backend, and improves the flexibility and accuracy of the audio broadcast of the broadcast end.

[0065] On the basis of the above embodiment, the broadcast end further includes an ultrasonic generator and an ultrasonic receiver, which are respectively used for transmitting and receiving ultrasonic data. The broadcast end and the control end perform data transmission through a communication network. In the case of a failure of communication module 140, the broadcast end and the control end are disconnected, resulting in the inability to transmit environmental data and broadcast data. To solve the above technical problem, by setting an ultrasonic generator and an ultrasonic receiver in the broadcast end, communication between broadcast ends can be achieved through the ultrasonic generator and the ultrasonic receiver in the case of disconnection between the broadcast end and the control end, so as to realize data transmission with the control end by means of other broadcast ends.

[0066] Optionally, the decision-making module 130 sends a first heartbeat signal to the control end through the communication module and receives a second heartbeat signal sent by the control end; in the case of not receiving the second heartbeat signal after a preset time interval of sending the first heartbeat signal, it is determined that the broadcast end and the control end are disconnected. Among them, the first heartbeat signal can be sent periodically to verify the periodic communication connection between the broadcast end and the control end. By verifying the communication connection, the normal sending of environmental data and the normal receiving of broadcast data are ensured, and in the case of disconnection, self-decision of the broadcast end is performed through the decision-making module 130.

[0067] When the broadcast end and the control end are disconnected, the decision-making module 130 transmits the information to be transmitted to the ultrasonic generator; the ultrasonic generator converts the information to be transmitted into an ultrasonic signal and transmits it. Among them, the information to be transmitted can include environmental data and device identification. The ultrasonic signal can be a sound wave signal with a frequency exceeding 20 kHz, and data transmission between broadcast ends can be realized without affecting the broadcast function of the broadcast end, so as to send environmental data to other broadcast ends in the case of disconnection and send the environmental data to the control end by means of other broadcast ends.

[0068] The ultrasonic receiver at the broadcasting end receives the ultrasonic signals transmitted by other broadcasting ends, parses the ultrasonic signals into information to be transmitted, and sends the information to be transmitted to the decision-making module 130; the decision-making module 130 transmits the information to be transmitted to the control end through the communication module. It can be understood that after the ultrasonic receiver receives the ultrasonic signals transmitted by other broadcasting ends, it determines whether its own device is disconnected from the control end. If so, it converts the environmental data and device identifier collected by its own device into ultrasonic signals, and transmits the converted ultrasonic signals and the received ultrasonic signals through the ultrasonic generator until the broadcasting end that receives the ultrasonic signals can send the data to be transmitted in the ultrasonic signals to the control end. Exemplarily, see Figure 3 , Figure 3 which is a schematic diagram of data transmission in the case of disconnection provided by an embodiment of the present invention.

[0069] In some embodiments, when the broadcasting end is disconnected from the control end, the decision-making module 130 determines the disconnection reason according to the detected environmental data. Correspondingly, the information to be transmitted may include the disconnection reason and the device identifier. Among them, the disconnection reason includes device reasons and environmental reasons. Specifically, it is determined whether the conditions for disconnecting the broadcasting end are met in the detected environmental data. If so, it is determined that the disconnection reason is an environmental reason. If not, it is determined that the disconnection reason is a device reason. Among them, the conditions for disconnecting the broadcasting end include, but are not limited to, the environmental humidity data being greater than the preset humidity value, the environmental temperature data being less than the first temperature value, or being greater than the second temperature data, etc., which are not limited here.

[0070] The decision-making module 130 makes self-decisions when the broadcasting end is disconnected from the control end, determines the broadcast data according to the environmental data, and sends the broadcast data to the broadcast module; the broadcast module 140 outputs the broadcast data.

[0071] The decision-making module 130 obtains the broadcast data sent by the control end before disconnection, and determines whether there is a contradiction between the broadcast data and the environmental state corresponding to the collected environmental data. If not, it plays the broadcast data. If so, it generates new broadcast data according to the environmental data and plays the new broadcast data. Specifically, in the case where none of the environmental data reaches the warning condition, the broadcast data stored locally, such as music, is called. When any environmental data reaches the warning condition, broadcast data containing warning information is generated. Further, the warning level range of each type of environmental data can be preset in advance, and according to the warning level range to which the environmental data belongs, the broadcast data corresponding to the environmental data type and the warning level range is called for playback.

[0072] The technical solution of this embodiment determines the connection status between the broadcast end and the control end in real time. In the case of disconnection, it realizes data transmission with the control end through other broadcast ends and makes self-decisions to adaptively generate broadcast data, improving the adaptability in different environmental states and reducing the dependence on the control end.

[0079] Based on the above embodiment, optionally, in the case of disconnection between the broadcast end 1 and the control end 2, the information to be transmitted is converted into an ultrasonic signal and transmitted; and, the ultrasonic signal transmitted by other received broadcast ends is parsed into the information to be transmitted, and the information to be transmitted is sent to the control end 2.

[0080] Based on the above embodiments, optionally, the broadcasting end 1 sends a first heartbeat signal to the control end 2 and receives a second heartbeat signal sent by the control end 2; in the case where the second heartbeat signal is not received after a preset time interval for sending the first heartbeat signal, it is determined that the broadcasting end 1 is disconnected from the control end 2.
