The information demodulator (112) is used to demodulate the broadcast signal output by the information receiver (111) to obtain the corresponding normal audio digital signal, and output the normal audio digital signal to the digital audio processor (113). The digital audio processor (113) is used to receive the normal audio digital signal output by the information demodulator (112), and perform signal quality improvement processing on it, including denoising, equalization, compression and other steps, aiming to improve the intelligibility and intelligibility of the audio signal, and output the emergency audio digital signal after signal quality improvement processing to the power amplifier (114). In addition, the digital audio processor (113) also has an automatic volume adjustment (AVC) function, which can automatically adjust the volume according to the environmental noise to ensure that the sound played can cover each area underground. The power amplifier (114) is used to receive the emergency audio digital signal output by the digital audio processor (113) and convert it into an electrical signal of a certain power to drive the loudspeaker (115) to emit sound. In this embodiment, the power amplifier (114) adopts high-efficiency digital power amplifier technology, which has the advantages of high power conversion efficiency and low distortion, and the power amplifier (114) also has an overload protection function, which can automatically cut off the output when the input signal is too large to protect the loudspeaker (115) from being damaged. The output power of the power amplifier (114) is matched according to the size of the underground area and the impedance of the loudspeaker (115) to ensure that the loudspeaker (115) can emit enough sound to cover each area underground. The loudspeaker (115) is the final output device of the loudspeaker station (11), responsible for converting the electrical signal output by the power amplifier (114) into sound. In this embodiment, the loudspeaker (115) can be a mine intrinsically safe type speaker box, and ensure that it has the advantages of wide frequency response range and low distortion. In addition, the loudspeaker (115) also has the functions of waterproof and dustproof, which can adapt to the harsh working environment underground. The arrangement of the loudspeaker (115) is reasonably planned according to the size and shape of the underground area to ensure that the sound can uniformly cover each area.
[0028] Through the above optional implementation, the emergency broadcast terminal (1) realizes the whole process from receiving the broadcast signal sent by the emergency broadcast host (33) to demodulating, signal quality improving processing, power conversion, overload protection, and finally converting the electrical signal into sound and uniformly covering each area underground through the efficient cooperation of the information receiver (111), the information demodulator (112), the digital audio processor (113), the power amplifier (114) and the sound (115). The digital audio processor (113) adopts optimization steps such as noise reduction, equalization and compression, improves the intelligibility and intelligibility of the audio signal, and is equipped with an automatic volume adjustment function, which can automatically adjust the volume according to the environmental noise to ensure the sound coverage effect. The power amplifier (114) adopts high-efficiency digital power amplifier technology, and the output power is optimized according to the size of the underground area and the sound impedance matching, to ensure that the sound (115) can emit a large enough sound. The sound (115) is designed as a mine intrinsically safe type, with characteristics such as wide frequency response range and low distortion, and has waterproof and dustproof functions, which can adapt to the harsh environment underground and finally uniformly cover each area underground.
[0029] In an optional embodiment, the smart mine emergency broadcasting system further comprises power supply devices, namely, a mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply arranged in the mine and an uninterruptible power supply arranged outside the mine, to ensure that the system can stably operate under various environments inside and outside the mine. The mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply is a power supply device specially designed for the mine environment, which has double protection features of explosion-proof and intrinsic safety. Through the explosion-proof performance, it can effectively prevent the explosion flame and heat from spreading to the outside of the mine when an explosion occurs inside the electrical equipment, thereby protecting the safety of the mine. Through the intrinsic safety performance, it ensures that the sparks or heat generated by the power supply in a fault state are not enough to ignite the combustible gas or dust in the mine, further improving the safety. The output end of the mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply is directly connected to the emergency broadcasting terminal (1) and the underground ring switch (21), providing stable and reliable direct-current power supply for them. In the complex and variable environment inside the mine, the mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply can ensure the stable operation of the emergency broadcasting system and the communication network, providing strong protection for information transmission in emergency situations. At the same time, the uninterruptible power supply is arranged outside the mine, and its output end is connected to the input end of the mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply through a mine-used power cable, providing uninterrupted power supply for the power supply devices inside the mine. When the power grid outside the mine fails or is powered off, the uninterruptible power supply can quickly start to provide emergency power for the power supply devices inside the mine, ensuring the continuous operation of the emergency broadcasting system and the communication network. In addition, the output end of the uninterruptible power supply is also connected to the monitoring and dispatching room (3), the wellhead ring switch (22), the core switch (23), and the monitoring room ring network switch (24) to provide power protection. In emergency situations, the stable operation of the monitoring and dispatching room (3), the wellhead ring switch (22), the core switch (23), and the monitoring room ring network switch (24) is crucial for the safety management and emergency response of the mine.
[0030] The working principle of the power supply device of the smart mine emergency broadcasting system is as follows: in the normal working state, the power grid outside the mine supplies power to the mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply through the uninterruptible power supply, which in turn provides power for the emergency broadcasting terminal (1), the underground ring switch (21), and other devices inside the mine. At the same time, the uninterruptible power supply also provides power protection for the monitoring and dispatching room (3), the wellhead ring switch (22), the core switch (23), and the monitoring room ring network switch (24). When the power grid outside the mine fails or is powered off, the uninterruptible power supply can quickly start to convert the stored electrical energy in the battery pack into alternating current, providing emergency power for the power supply devices inside the mine. In this process, the mine-used explosion-proof and intrinsic safety type direct-current stabilized power supply can maintain the stability of the output voltage, ensuring the stable operation of the emergency broadcasting system and the communication network.
