BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 A detection flow chart of a tool for detecting the IP communication protocol standard of an emergency broadcast terminal provided by the present invention. DETAILED DESCRIPTION

[0019] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0020] like Figure 1 As shown, the present invention provides a tool for detecting the IP communication protocol standard of emergency broadcast terminals, which includes: an acquisition module, a protocol parsing module, a verification module, a data evaluation and a terminal asset inventory module. The acquisition module is used to collect IP communication data. The protocol parsing module parses the IP communication data according to the corresponding industry standards of emergency broadcasting, and obtains key information of the IP communication data during parsing; and parses the emergency broadcast message message according to the corresponding standards. The verification module verifies the parsed data, compares the communication protocol with the industry standard, and determines whether the IP communication protocol of the emergency broadcast terminal complies with the industry standard. The data evaluation module evaluates the parsed and verified data and generates an evaluation report. The terminal asset inventory module analyzes all collected terminal device information, confirms the brand and model of the terminal device, and forms an asset list.

[0021] Specifically, the acquisition module collects IP communication data by accessing the emergency broadcast system terminal. Based on the acquired IP communication data, the protocol parsing module parses the emergency broadcast terminal according to the industry standard to identify the message information in the data, determine whether the message body content complies with the specification, and extract the key information. Based on the extracted information, the verification module verifies the parsed data to ensure the integrity and authenticity of the data. The parsed communication protocol is compared with the industry standard to determine whether the IP communication protocol of the emergency broadcast terminal complies with the industry standard. Based on the parsed and verified data, the data evaluation module evaluates the communication data of the emergency broadcast system to detect anomalies or errors in the communication protocol data packets, and whether the terminal feedback time meets the standard requirement of 15 seconds (15 seconds is the industry standard time), and finally generates an evaluation report. By comparing and analyzing the communication data and the evaluation report, the information that complies or does not comply with the emergency broadcast system is automatically detected and located, and relevant suggestions are put forward. The terminal asset inventory module will analyze the collected terminal equipment information, confirm the online and offline status of the terminal equipment, the terminal brand and terminal model, and form an asset list.

[0022] In this embodiment, when the protocol parsing module parses the protocol, it parses the IP communication data of the emergency broadcast terminal according to the industry standard. The parsing method in the prior art is usually for a wide range of communication protocols, rather than specific to the IP communication protocol standard of the emergency broadcast terminal, which may result in the failure to fully meet its specific requirements and details when parsing a specific industry standard, such as specific format, data structure and processing mechanism requirements. The parsing method is not only based on a general parsing method, but also deeply integrates the specific requirements of the emergency broadcast terminal IP communication protocol standard, including the emergency broadcast platform and the emergency broadcast terminal IP communication protocol. When parsing IP communication data, it is first necessary to identify and parse the TCP / IP protocol header to obtain key information such as the source address, destination address, port number, etc. of the data, and then parse the emergency broadcast message message, and parse the message body file, message instruction file and other information according to the standard specified in GD / J089-2018. Moreover, the parsing method adopts a modular design, which is convenient for subsequent expansion and maintenance. With the update or change of industry standards, it can adapt to new requirements more quickly to ensure the accuracy of the parsing results and full compliance with industry standards. For example, when the terminal receives an emergency broadcast command message from the upper-level platform, it will first parse the protocol header to confirm the source and destination of the message, and then further process the information to determine whether the main content of the message complies with the specification and extract key information, such as information content, release time, type, etc. Among them, the industry standards analyzed in this article include but are not limited to "GDJ 089-2018 Technical Specifications for Emergency Broadcast Loudspeaker Systems", "GDJ 089-2018 Technical Specifications for Emergency Broadcast Loudspeaker Systems" and "National Emergency Platform System Information Resource Classification and Coding Specifications".

[0023] In this embodiment, the verification module is based on the parsed data, using relevant verification algorithms and signature verification mechanisms, including the length of the digital signature information, the digital signature time, the signature certificate number, the digital signature, and the CRC32 value of the data packet, wherein the 32-bit decoder of the CRC32 value is composed of 14 adders and 32 delay units Z(i), and operates bit by bit. The hardware structure of the CRC32 value decoding can optimize the calculation speed and reduce resource usage, ensuring that the emergency broadcast system can operate stably in scenarios with high concurrency and high real-time requirements. Because the emergency broadcast terminal must ensure timely and accurate data transmission, each bit can be accurately controlled and processed according to the bit operation, which helps to ensure the accuracy and reliability of the decoding. The input of the CRC decoder is added to the output of the delay unit Z(31), and the result is transmitted to the input of the delay unit Z(0) and other adders. The parsed data is verified to ensure the integrity and authenticity of the data. As an important channel for the release of emergency warning information, the emergency broadcast system has formulated relevant standards to regulate the technical requirements and protocol specifications of emergency broadcast terminals. The terminal protocol industry standard ensures the accurate, rapid and extensive dissemination of emergency information. The parsed communication protocol is compared with the industry standard to determine whether the IP communication protocol of the emergency broadcast terminal complies with the industry standard. The parsed communication protocol is compared with the communication protocol in the industry standard one by one to determine whether each item is consistent, and the number and specific content of the non-conforming items are counted.

[0024] Based on the parsed and verified data, the data evaluation module detects anomalies or errors in the communication protocol data packets, such as format errors, data errors, etc., and evaluates the communication data of the emergency broadcast system. This evaluation method may combine a variety of technical means and more stringent and comprehensive security standards and specifications, such as format verification, data integrity verification, data content verification and security evaluation, to form a comprehensive evaluation system. This comprehensive evaluation method can detect anomalies or errors in communication protocol data packets more comprehensively and accurately, improve the accuracy and reliability of the evaluation, and finally generate an evaluation report.

[0025] By comparing and analyzing communication data and evaluation reports, including data content verification (data consistency check to ensure that the data complies with business logic and relevant parameters match), security assessment (security of communication data, whether the digital signature in the data packet is valid), etc., the tool will verify whether the overall structure of the data complies with the specifications, and check each field in the data one by one to ensure that they match the fields in the protocol specifications and meet the requirements of the specifications in the protocol, such as data type, data range, enumeration value verification, etc. The data also includes detailed information on terminal instructions and returns, such as terminal source target, broadcast time and feedback time, so as to confirm whether the terminal broadcast time complies with the standard within 15 seconds (15 seconds is the standard time required by the industry), and locate the information that complies or does not comply with the emergency broadcast system, and make relevant suggestions.

[0026] In addition to collecting and analyzing terminal information, we will also conduct an asset inventory of the terminal equipment to determine the online and offline status of the terminal, as well as information such as the terminal brand and model, and form an asset list to compile into a final report.

[0027] In actual applications, users only need to connect the emergency broadcast system to the tool of the present invention and start the corresponding detection program to obtain the detection results, problem assessment report and asset inventory report of whether the emergency broadcast terminal IP communication protocol complies with industry standards.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
