Communication method for network communication application layer of ancient book protection box system

Abstract

The invention belongs to the wireless network communication technology and applies to a network communication technology in an indoor high-density wireless environment. According to a communication method for a network communication application layer of an ancient book protection box system, multi-functional instruments are in wireless communication with a relay device, the relay device is in wired communication with a central control center, and the protocol stipulates structures and formats of data and command information, stipulates an inquiry response relation between commands and data information and stipulates a transmission sequence of the commands and the data information. Real-time performance of communication is improved while communication reliability of a wireless network is guaranteed through combination of a UDP (user datagram protocol) and an application layer retransmission mechanism; under the action of unified control for communication initiation and termination modes, real-time delivery of communication information is guaranteed, and the utilization rate of channel resources is increased; due to detailed regulations of transmission data formats, coding and decoding efficiency is improved; by means of multi-digit coding confirmation for key information, acquisition reliability of key parameters of an ancient book packaging box is improved.

Description

technical field [0001] The invention belongs to the wireless network communication technology, and is suitable for the network communication technology in the indoor high-density wireless environment. Background technique [0002] In 1983, the International Organization for Standardization ISO issued the standard communication system using the official document ISO7498 international standard based on Open Systems Interconnection (hereinafter referred to as "OSI"). The goal of OSI is to create a system in which any vendor computer system connected to any network An open system networking environment that can freely share data with any other computer system on that network. The main content of OSI is a seven-layer protocol architecture, including physical layer, data link layer, network layer, transport layer, session layer, Although the presentation layer and application layer have clear concepts and complete theory, they are complicated and impractical. The subsequent TCP / I...

Problems solved by technology

[0007] 1. This method guarantees the real-time performance of wireless communication by adopting the UDP protocol at the transport layer, and retransmits lost frames or error frames at the application layer, thereby ensuring the reliability of wireless communication and solving the problem of real-time performance of traditional wireless networks. The problem that reliability is difficult to be guaranteed at the same time;
