Method and system for blind area data supplementary transmission by using extended transparent transmission protocol

Abstract

The invention relates to a method and a system for blind area data supplementary transmission by using an extended transparent transmission protocol. The method comprises the following steps: uploading blind area supplementary transmitted data generated by a vehicle-mounted terminal to a platform according to the extended transparent transmission protocol, and uploading the real-time location data according to department standard location information protocol; distinguishing the extended transparent transmission protocol from the department standard location information protocol through package heads, wherein the extended transparent transmission protocol self-nests the department standard location information protocol, and transparent transmitted message content in the extended transparent transmission protocol has no limitation of length, and the principle of transmission by one data packet without sub-packets is adopted. The invention also provides a system for blind area data supplementary transmission by using the extended transparent transmission protocol. The system comprises a vehicle-mounted terminal and a platform, and has the advantages that the platform can conveniently distinguish real-time location data uploaded by the vehicle-mounted terminal from blind area supplementary transmitted data, and reduces uploading times and saves flow.

Description

technical field [0001] The present invention relates to the use of the transparent transmission protocol in the "Road Transport Vehicle Satellite Positioning System Terminal Communication Protocol and Data Format" (hereinafter referred to as the Ministry Standard), and more specifically, relates to a method of using the extended transparent transmission protocol for supplementary data transmission in blind areas methods and systems. Background technique [0002] The ministry standard specifies the communication protocol and data format between the vehicle-mounted terminal of the satellite positioning system of road transport vehicles and the supervision / monitoring platform, and is applicable to the vehicle-mounted terminal of the satellite positioning system of road transport vehicles (referred to as the vehicle terminal) and the supervision / monitoring platform (referred to as the platform) The communication between the vehicles, the development of the vehicle terminal is ba...

Problems solved by technology

In the actual development process, the ministry standard agreement does not have a clear specification for the supplementary transmission of blind area data. The current method of use is to perform supplementary transmission of blind area data after the network is reconnected under the premise that there is blind area data. At the same time , the real-time location data is also continuously uploaded, and the currently used supplementary transmission protocol is the same as the real-time location information upload protocol, so when the monitoring platform obtains real-time location information and blind area data information, it is difficult to distinguish between real-time location data and blind area supplementary transmission data, which is not conducive to the acquisition and screening of two different data
