Embodiment Construction

[0037] GPRS (General Packet Radio Service) is the abbreviation of General Packet Radio Service. GPRS is one of the contents realized by the GSMPhase2.1 specification, which can provide a higher data rate than the existing GSM network 9.6kbit / s. GPRS uses the same frequency band, frequency bandwidth, burst structure, wireless modulation standard, frequency hopping rules and the same TDMA frame structure as GSM. Therefore, when building the GPRS system on the basis of the GSM system, most of the components in the GSM system do not need to be changed in hardware, but only need to be upgraded in software.

[0038] CDMA 1X refers to the first stage of cdma2000 (the rate is higher than IS-95, lower than 2Mbps), the forward link data rate can reach 144Kbps, the network part introduces packet switching, and can support mobile IP services. Among the international proposals for wireless interfaces of third-generation mobile communications, W-CDMA and cdma2000 are the most widely notice...

Abstract

The present invention relates to a multi-link wireless mobile industrial control integrated data-transmission system, which adopts a multi-link terminal to quickly and dependably transmit the text data, picture data and audio/video data to a server, and simultaneously can quickly acquire the text data, picture data and audio/video data from the server, thereby effectively resolving the data transmission problem under manufactory complicated environment. The invention adopts a double-card multi-link to perform dependable concurrent transmission to the data, the multi-link wireless double-card data-transmission system adopts a user-defined data frame format, a TCP and UDP combined communication mode, and adopts an intellectualized load proportion method, error control method and safety control method.

Description

1. Technical field: [0001] The present invention relates to a wireless data transmission system, in particular to a multi-link wireless mobile industrial management and control integration that supports multi-channel data concurrent transmission, automatic load balancing, and supports link backup functions that can be used in complex application environments in factories. data transfer system. 2. Background technology: [0002] With the rapid development of wireless network technology, the demand for wireless data transmission and remote monitoring applications in industrial enterprise environments is increasing. Due to the complex environment of the factory has high requirements for the reliability of the wireless network, and the harsh working environment of the factory equipment, the requirements for data transmission are relatively high. The existing wireless data transmission system cannot meet the above requirements of the factory. 3. Contents of the invention [0...
