[0029] For easy understanding, please refer to Figure 1The utility model provides an embodiment of broadcast prompting system, including broadcast console 100, networked power amplifier module 200, broadcast loudspeaker 300 and wearable smart device 400. Broadcast console 100 is connected with networked power amplifier module 200. Networked power amplifier module 200 includes network audio decoding module 2001 with MCU chip and post power amplifier module 2002. Network audio decoding module 2001 with MCU chip is used to generate ultrasonic signal when receiving the audio signal sent by broadcast console 100, and the ultrasonic signal and audio signal are mixed and exported to post power amplifier module 2002. Post power amplifier module 2002 is connected with broadcast loudspeaker 300. Wearable smart device 400 is provided with pickup microphone 4001, controller 4002 and vibration module 4003, and controller 4002 is connected with pickup microphone 4001 and vibration module 4003 respectively, and the pickup frequency range of pickup microphone 4001 is the frequency range of ultrasonic signal.

[0030] Need to explain, staff send the audio signal that needs broadcasting through broadcast console 100, and the audio signal of broadcasting can be the audio signal that records beforehand, can also be the audio signal of staff on -the -spot output through speaking to microphone 1001. The audio signal of broadcasting is received by network audio decoding module 2001 with MCU chip, and network audio decoding module 2001 with MCU chip receives the audio signal, decodes the audio signal and outputs on one hand, and generates an ultrasonic signal and outputs on the other hand, and post power amplifier module 2002 includes operational amplifier and power amplifier connected in turn, and the audio signal and ultrasonic signal are inputted to post power amplifier module 2002 and are mixed and amplified, and then are exported to broadcast loudspeaker 300 and broadcast, and the audio signal of broadcast loudspeaker 300 broadcast can be heard by human ear, and ultrasonic signal cannot be heard by human ear. The staff working in the work site wears wearable smart device 400, and pickup microphone 4001 of wearable smart device 400 picks up the ultrasonic signal broadcast loudspeaker 300 plays and transmits to controller 4002, and controller 4002 controls vibration module 4003 and vibrates, and therefore, the staff can feel the vibration through wearable smart device 400 in the way of tactile sensation, thereby knowing that broadcast console 100 is broadcasting at this time.

[0031] In an embodiment, the wearable smart device 400 is a smart bracelet. The staff wears the smart bracelet on the hand, and when the smart bracelet receives the ultrasonic signal, the smart bracelet vibrates, and the staff can perceive the occurrence of vibration with the hand, so as to know that the broadcasting console 100 is currently broadcasting. The power module of the wearable smart device 400 uses a solar power module 4004 as a power supply. The solar power module 4004 is arranged on the wearable smart device 400, converts solar energy into electric energy, and supplies power to the wearable smart device 400. Further, in order to avoid insufficient solar energy leading to the solar power module 4004 being unable to continuously supply power to the wearable smart device 400, a lithium battery module 4005 can also be arranged in the wearable smart device 400 as a backup power supply of the wearable smart device 400.

[0032] In an embodiment, the broadcasting console 100 is configured with an emergency broadcasting button 1002, and the emergency broadcasting button 1002 is connected with the network audio decoding module 2001 with an MCU chip. The broadcasting console 100 can have two broadcasting modes, one is a normal broadcasting mode, and the other is an emergency broadcasting mode. In the case that the emergency broadcasting button 1002 is not pressed, the audio signal directly broadcasted by the broadcasting console 100 is a normal broadcasting audio signal, and the ultrasonic signal generated by the network audio decoding module 2001 with an MCU chip is a single-frequency ultrasonic signal. In the case that the emergency broadcasting button 1002 is pressed, the network audio decoding module 2001 with an MCU chip obtains the signal that the emergency broadcasting button 1002 is turned on, and generates a multi-frequency ultrasonic signal. Further, the vibration module 4003 includes a primary vibration module and a secondary vibration module, and the vibration intensity of the primary vibration module is greater than that of the secondary vibration module. When the pickup microphone 4001 of the wearable smart device 400 picks up a single-frequency ultrasonic signal, the secondary vibration module is controlled to vibrate. When the pickup microphone 4001 of the wearable smart device 400 picks up a multi-frequency ultrasonic signal, the primary vibration module is controlled to vibrate.

The vibration module 4003, the vibration warning light 4006 and the buzzer 4007 are simultaneously configured on the wearable smart device 400, which can simultaneously prompt the staff in a tactile, audible and visual manner, and can completely ensure that the staff knows the occurrence of the broadcast.

[0034] In one embodiment, the wearable smart device 400 is further configured with a toxic gas sensor 4008, and the toxic gas sensor 4008 is connected with the controller 4002. The toxic gas sensor 4008 is installed on the outer surface of the wearable smart device 400, and is used to detect toxic gas in the working environment of the staff. When the concentration of the toxic gas detected is higher than the threshold value, the controller 4002 can also control the vibration module 4003 to vibrate for reminding. Among them, in order to distinguish from the vibration of the broadcast prompt, the controller 4002 controls the first level vibration module to vibrate at intervals of a preset time, for example, the first level vibration module vibrates once every 0.5 seconds, so as to remind the staff to leave the area where the toxic gas is as soon as possible, and avoid personal safety accidents.
