Description

Technical Field

[0001] The invention discloses an emergency communication method combining short-range star flashes and wireless broadcasting, and relates to the technical field of wireless communications. Background Art

[0002] In modern society, the stability and reliability of communication networks are of vital importance. The wireless transmission distance between the current communication network receiving terminal and the base station is usually limited to a few kilometers. This limitation makes the communication network base station extremely vulnerable to being affected when an emergency or disaster occurs, and it is unable to receive emergency information from the communication network, which can easily lead to potential dangers.

[0003] Existing emergency communication solutions, such as satellite communications, have certain advantages in coverage, but due to their high costs and complex operating procedures, they are difficult to deploy quickly in emergency situations. Summary of the invention

[0004] In view of the problems of the prior art, the present invention provides an emergency communication method combining short-range star flash and wireless broadcasting, making full use of the low latency and anti-interference characteristics of star flash, the intelligence of AI technology and the broadband and wide coverage characteristics of radio communication to achieve communication guarantee in emergency situations, and can be widely used in production, transportation and many other aspects.

[0005] The specific scheme proposed by the present invention is:

[0013] Step 7: Use wireless short-range star flash to monitor the progress of emergency response in real time and receive feedback information.

[0014] Furthermore, in step 2 of the emergency communication method combining short-range star flashes with wireless broadcasting, a long short-term memory network LSTM or a Transformer architecture is used as an automatic speech recognition model.

[0015] The input audio signal is preprocessed, and the processed acoustic features are input into the automatic speech recognition model for speech recognition.

[0016] Furthermore, in step 3 of the emergency communication method combining short-range star flash and wireless broadcast, digital signature key management is performed: public key infrastructure PKI is used to generate and manage public keys and private keys,

[0017] During the signing process, the text information to be sent is hashed to generate a hash value, the hash value is encrypted using a private key, a digital signature is generated, and the original information and the digital signature are sent to the recipient together.

[0018] When verifying the digital signature in step 4, the receiver uses the sender's public key to decrypt the digital signature, obtains a hash value, performs a hash operation on the received text information, compares the two hash values ​​to see if they are consistent, and verifies the integrity and authenticity of the text information.

[0019] Furthermore, in step 7 of the emergency communication method combining short-range star flashes and wireless broadcasting, the Zigbee or LoRa protocol is used to send to relevant emergency response personnel and equipment, and the progress of the emergency response is monitored in real time, and feedback information is received.

[0027] The wireless short-range star flash module uses wireless short-range star flash to monitor the progress of emergency response in real time and receive feedback information.

[0028] Furthermore, the automatic speech recognition module of the emergency communication device combining short-range star flash and wireless broadcast adopts a long short-term memory network LSTM or a Transformer architecture as an automatic speech recognition model.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 It is a schematic flow chart of the method of the present invention.

[0037] Figure 2 It is a flowchart of text information encryption and decryption processing. DETAILED DESCRIPTION

[0038] Automatic speech recognition (ASR) is a technology that converts speech signals into text and is widely used in voice assistants, voice translation, and telephone customer service. ASR systems usually consist of multiple modules, including acoustic models, language models, and decoders.

[0039] Acoustic model: The acoustic model is responsible for matching the acoustic features of the speech signal with the corresponding phonemes or words. Deep neural networks, such as LSTM and convolutional neural networks (CNNs), are widely used to build acoustic models to improve recognition accuracy.

[0040] Language model: The language model is used to perform contextual analysis on the recognition results and determine which word combinations are more reasonable in a specific context. Common language models include the N-gram model and deep learning-based models such as Transformer.

[0041] Decoder: The decoder is responsible for combining the output of the acoustic model and the language model to generate the final text result. Greedy algorithms or beam search algorithms are usually used in the decoding process to improve the efficiency and accuracy of recognition.

[0042] Digital signature technology is an encryption technology used to verify the authenticity and integrity of information. It is based on public key cryptography and ensures data security by signing and verifying information.

[0043] Signing process: The sender uses his private key to hash the information, then encrypts the hash value to generate a digital signature. This signature is sent to the receiver along with the information.

[0044] Verification process: The receiver uses the sender's public key to decrypt the digital signature and obtain a hash value. At the same time, the receiver performs a hash operation on the received information and compares whether the two hash values ​​are consistent. If they are consistent, it means that the information has not been tampered with and the source is reliable.

[0045] Digital signatures are widely used in fields such as email, software distribution, and financial transactions to ensure the security and authenticity of data.

[0046] Short-range Blink Technology: Wireless short-range Blink technology is a highly efficient and low-latency communication technology. This technology has the following characteristics:

[0047] Fast response: This technology can receive instructions and respond in a very short time, ensuring that relevant equipment can quickly enter the alarm protection state in an emergency. Its low latency feature makes information transmission almost real-time, thereby improving the efficiency of emergency handling.

[0048] Domestic reliability: The development and application of this technology is based on domestically developed communication protocols and equipment, ensuring reliability and stability under special circumstances. This feature allows communication to remain unimpeded even when facing the risk of external technology dependence.

[0049] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0050] Example 1

[0051] The present invention provides an emergency communication method combining short-range star flash and wireless broadcast, comprising:

[0052] Step 1: Based on the emergency environment, release emergency information through radio broadcasts.

[0053] Step 2: Use the automatic speech recognition model to convert the emergency messages received in real time into text information.

[0054] The long short-term memory network LSTM or Transformer architecture is used as the automatic speech recognition model.

[0055] The input audio signal is preprocessed, such as noise reduction, feature extraction such as MFCC, etc., and the processed acoustic features are input into the automatic speech recognition model for speech recognition.

[0056] Step 3: Digitally sign the processed text information.

[0057] Key management for digital signatures: Public key infrastructure (PKI) is used to generate and manage public and private keys.

[0058] During the signing process, the text information to be sent is hashed to generate a hash value, the hash value is encrypted using a private key, a digital signature is generated, and the original information and the digital signature are sent to the recipient together.

[0059] Step 4: Verify the digital signature and encrypt the text information for transmission. When verifying the digital signature, the receiver uses the sender's public key to decrypt the digital signature, obtain the hash value, perform a hash operation on the received text information, compare the two hash values ​​to see if they are consistent, and verify the integrity and authenticity of the text information.

[0060] Step 5: Use natural language processing methods to decrypt the received text information and identify the semantics of the text information, extract key information for subsequent operations.

[0061] Step 6: Send the processed text information to relevant emergency response personnel and equipment using wireless short-range star flash.

[0062] The appropriate scrambling algorithm is selected, such as frequency hopping, spread spectrum technology, etc., to ensure that the information will not be demodulated by unauthorized users during transmission. At the sending end, the information is scrambled and embedded into different frequencies using a preset scrambling sequence. At the receiving end, only authorized devices can use the same scrambling sequence for descrambling and restore the original information.

[0063] Step 7: Use wireless short-range star flash to monitor the progress of emergency response in real time and receive feedback information. Zigbee or LoRa protocol can be used to send to relevant emergency response personnel and equipment, and monitor the progress of emergency response in real time and receive feedback information.

[0064] The method of the present invention has a wide range of application prospects. It can be used not only in the fields of emergency communications, natural disaster response and public safety management, but also in smart homes, industrial automation and environmental monitoring. Through the implementation of this method, efficient and real-time information transmission and security can be achieved, providing strong support for various emergency responses and improving the overall emergency management capabilities of society. In addition, the flexibility and scalability of this technology enable it to adapt to different application requirements and provide greater convenience and security for people's lives and work.
