Abstract
Description
technical field
[0001] The invention relates to a protocol conversion device in the field of network technology, and is a GPS device access gateway device. Background technique
[0002] The data transmission method of the existing GPS system is simple. Usually, the TCP protocol is used to upload the positioning data obtained by the GPS module to the server without processing the data or managing the communication mode. In large frameworks such as video recording, this is not conducive to integration with other data, causing inconvenience in managing multiple data. Audio and video data usually have their own applicable communication protocols, such as RTP, etc., which leads to the coexistence of data of multiple protocols within the same framework, which urgently requires an application layer protocol that can manage data indiscriminately. The SIP protocol is formulated by the IETF. It is an application layer control signaling protocol used to establish, modify, and terminat...

Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings.
[0028] refer to Figure 1 to Figure 5 A GPS device access gateway device, the bottom layer of the access gateway device is a thread pool module for task scheduling, the module controls the TCP communication module, the SIP communication module and the protocol conversion module, and realizes the functions of the entire access gateway device. The communication between the server and the access gateway device is through the TCP communication module, and the GPRS network is used for interaction, and the SIP+TCP protocol is adopted; the TCP connection between the access gateway device and the GPS device is performed through the TCP communication module. The data communication between the access gateway device and the server adopts the SIP+XML protocol, the data communication between the access gateway device and the GPS device adopts ordinary binary data, encapsulated in t...
