[0016] Embodiments of the invention facilitate the simultaneous and rapid deployment of emergency messages to different regions of an event space, and enable the messages to be centrally and easily updated as the situation changes.

[0017] Figure 1 illustrates an outdoor emergency broadcasting system 100 according to one embodiment of the invention.

[0018] The system 100 comprises a first outdoor emergency broadcasting device 102a, a second outdoor emergency broadcasting device 102b and at least one server device 104 in wireless communication with each of one or more user device(s) 106 and the broadcasting devices 102a, 102b.

[0019] It may be desirable to provide different messages to different zones or regions of an event space. For this purpose, at least one respective outdoor emergency broadcasting device 102a, 102b is provided for each zone or region. Each outdoor emergency broadcasting device 102a, 102b is arranged to broadcast an audible emergency message within its respective region as will be explained. Each outdoor emergency broadcasting device 102a, 102b may additionally be used to broadcast other information, such as venue information, parking information, travel information or advertisements. In this way, the outdoor emergency broadcasting device 102a, 102b can serve a dual function when no emergency occurs.

[0020] In the illustrated example, two outdoor emergency broadcasting devices are provided. The first outdoor emergency broadcasting device 102a is located at a first location 112a, or first zone 112a of the event space, and the second outdoor emergency broadcasting device 102b is located at a second location 112b, or second zone 112b, of the event space. Although only two zones each having a respective device therein are illustrated, in other embodiments the event space may have additional zones and therefore the outdoor emergency broadcasting system 100 may comprise additional outdoor emergency broadcasting devices.

[0021] In some embodiments, more than one outdoor emergency broadcasting device may be provided for a given zone, for example if a zone is large and requires multiple outdoor emergency broadcasting devices in order to provide audible coverage across the zone.

[0022] As discussed, it may be desired to provide a different emergency message at the first zone 112a to the second zone 112b.

[0023] Advantageously, the outdoor emergency broadcasting system 100 facilitates the central management and deployment of emergency messages to different zones of the event space. This is achieved via at least one central server device 104, illustrated in Figure 1 as a cloud device 104 provided as part of a cloud service. The at least one central server device 104 is in communication with one or more user devices 106 via one or more wireless networks.

[0024] A server system 104 according to one embodiment is illustrated schematically in Figure 2A. In the illustrated embodiment, the server system comprises one server device 200, however in other embodiments the functions of the server system 104 described below may be distributed across a plurality of devices 200. The server device 200 is located remotely to each of the first outdoor emergency broadcasting device 102a and second outdoor emergency broadcasting device 102b.

[0025] The server device 200 comprises processing means 206 and memory means 208. The processing means 206 may be one or more electronic processing device 206 which operably executes computer-readable instructions. The memory means 208 may be one or more memory device 208. The memory means 208 is electrically coupled to the processing means 206. The memory means 208 is configured to store instructions, and the processing means 206 is configured to access the memory means 208 and execute the instructions stored thereon to perform the functions described below.

[0026] The server device 200 further comprises a communication module 212 for communicating with each of the first outdoor emergency broadcasting device 102a, second outdoor emergency broadcasting device 102b and user device 106. The communication module 212 comprises hardware for performing wireless communication, such as via one or more networks. In particular, the communication module 212 may support communication via a 4G network, 5G network or the like.

[0027] The server device 200 is configured to receive, via the communication module 212, an indication of an emergency event from a user device.

[0028] The user device 106 may be any personal computing device with wireless communications capabilities such as a laptop, personal computer, tablet or mobile phone. Although one user device 106 is illustrated, it will be appreciated that any number of user devices 106 may be in communication with the server device 200. For example, an end user may access the cloud based service and communicate with the server device 200 through a mobile application, web application or similar.

[0029] The indication of the emergency event may be provided at the user device 106 in the form of a user input, such as a touch input, voice input or the like, and communicated to the server device 200 over the one or more wireless networks.

[0030] In response to receiving the indication, the server device 200 generates emergency alert data to be transmitted to each of the first outdoor emergency broadcasting device 102a and second outdoor emergency broadcasting device 102b.

[0031] With reference to Figure 2B, the server device 104 is configured to access first location data 210a associated with the first location and second location data 210b associated with the second location. In the illustration, the first location data 210a and second location data 210b are stored in the memory 208 of the server device 104, however the first location data 210a and second location data 210b may be stored in any location accessible to the server device 104, such as m the user device 106, first outdoor emergency broadcasting device 102a, or any other external storage with which the server device 104 is communicably coupled.

[0032] The first location data 210a comprises information for providing an emergency message at the first location. In particular, the first location data 210a may be audio data comprising a pre-recorded emergency message for playing at the first location. In other embodiments, the first location data 210a may comprise textual data indicating an emergency message for playing at the first location. For example, the message may comprise one or more of a location of an emergency exit associated with the first location; a location of a safe zone associated with the first location; or a warning or health and safety alert associated with the first location.

[0033] The first location data 210a further comprises an indication of which outdoor emergency broadcasting devices are associated with the first location. For example, the first location data 210a may comprise a list of device IDs associated with each outdoor emergency broadcasting device at the first location. In the illustrated example of Figure 1, this is only the one first outdoor emergency broadcasting device 102a.

[0034] Likewise, the second location data 210b comprises information for providing an emergency message at the second location. This facilitates providing a different message at the second location to the first location. As with the first location data 210a, the second location data 210b may be audio data comprising a pre-recorded emergency message for playing at the second location, or textual data indicating an emergency message for playing at the second location. For example, the message may comprise one or more of a location of an emergency exit associated with the second location; a location of a safe zone associated with the second location; or a warning or health and safety alert associated with the second location. This facilitates, for example, guiding different zones of the event space to different exits in an emergency, or providing different emergency instructions (for example, it may be desired to direct the first zone to an emergency exit, and instruct the second zone to stay in place).

[0035] The second location data 210b further comprises an indication of which outdoor emergency broadcasting devices are associated with the second location. For example, the second location data 210b may comprise a list of device IDs associated with each outdoor emergency broadcasting device at the second location. In the illustrated example of Figure 1, this is only the one second outdoor emergency broadcasting device 102b.

[0036] Each of the first location data 210a and second location data 210b may be configurable based on user input from the user device 106. In particular, an event host or other user of the user device 106 can update the first location data 210a and second location data 210b m real time during use of the system. This may include reconfiguring the zones of the event space, to change which outdoor emergency broadcasting devices are associated with each location, or updating the emergency message to be played at each location by uploading a new pre-recorded message or textual data.

[0037] In response to receiving the indication of an emergency event, the server device 104 is configured to determine first emergency alert data in dependence on the first location data 210a, and determine second emergency alert data in dependence on the second location data 210b. In the case that the first location data 210a and second location data 210b comprise prerecorded messages, determining the first emergency alert data and second emergency alert data may comprise retrieving the pre-recorded messages. In the case where the first location data 210a and second location data 210b comprise textual data, the server may be configured to generate the emergency alert data by using a text-to-speech algorithm. In this way, audio messages can be generated on-the-fly when the information is updated. In this case, the first emergency alert data is generated by applying a text-to-speech algorithm to the first location data 210a, and the second emergency alert data is generated by applying a text-to-speech algorithm to the second location data 210b.

[0038] The server device 104 then transmits the first emergency alert data to the first outdoor emergency broadcasting device 102a for providing a first audible emergency message and transmits the second emergency alert data to the second outdoor emergency broadcasting device 102b for providing a second audible emergency message.

[0039] It will be appreciated that the system 100 therefore facilitates the generation and deployment of emergency messages in a zoned event space, such that the messages can be centrally updated and deployed simultaneously to ensure a crowd is provided with accurate and up to date messaging.

[0040] With reference to Figures 3 A to 3D, there is illustrated an outdoor emergency broadcasting device 300 according to one embodiment.
