The Ministry of Transport pointed out that the original intention of transportation to deepen the reform of the taxi industry and encourage and develop new formats is to stimulate market vitality, and strive to build a diversified and differentiated travel service system to better meet the travel needs of the people. After some online ride-hailing platform companies have grown, they have not carried the necessary social responsibilities on their shoulders, but have spared no effort to infringe the interests of drivers and passengers. These companies only use online car-hailing as a tool to increase "traffic" and "valuation", and they don't take the people's sense of gain at heart. They only look at the faces of investors, not the feelings and experience of passengers, and the drivers. Objective needs.
JT/T 794-2019 "Technical Requirements for Road Transport Vehicle Satellite Positioning System Vehicle Terminals"
This standard specifies the general requirements, functional requirements, performance requirements and installation requirements of the vehicle-mounted terminal of the road transportation satellite positioning system (hereinafter referred to as the terminal).
This standard applies to the terminal equipment installed on the vehicle in the road transportation satellite positioning system.
JT/T 808-2019 "Road Transport Vehicle Satellite Positioning System Terminal Communication Protocol and Data Format"
This specification stipulates the Beidou compatible vehicle-mounted terminal (hereinafter referred to as the terminal) and supervision/supervision of the road transport vehicle satellite positioning system.
The communication protocol and data format between the control platforms (hereinafter referred to as the platform), including protocol foundation, communication connection, message processing, protocol classification and description, and data format.
After the platform software developers and GPS equipment developers have installed the standard development, they need to pass the Ministry of Transportation’s Ministry of Transport’s Ministry of Standards inspection and certification, and then they can participate in the software and hardware bidding in various places.
The function test of the platform by the Ministry of Transport mainly simulates the GPS terminal sending standard protocol data, and then tests whether it can receive the data correctly. Developers of GPS applications must understand and master these protocols. The platform protocols are mainly JT/TB808, 809 and extended supplementary protocols. At the same time, the protocol also applies the ministry-promulgated GB19056 standard for the driving recorder. /T796 is mainly a standard for hardware equipment, you can refer to it.
JTT 808-2019 road transport vehicle satellite positioning system terminal communication protocol and data format
GB/T35658 Technical requirements for the platform of the road transport vehicle satellite positioning system
JTT 794-2019-Beidou compatible vehicle terminal technical specification for road transport vehicle satellite positioning system
JTT 809-2019 Road Transport Vehicle Satellite Positioning System-Platform Data Exchange
Whether developing GPS equipment hardware or developing application software, we have to face a standard. This standard is the certification standard of road transport vehicle satellite positioning system issued by the Ministry of communications. It covers the parameters and function standards of GPS hardware equipment, the protocol standard of equipment uploading to application platform, and the technology of platform to platform interconnection and mutual transmission Standards. That is to say, all the application platform software developed according to the standard of the Ministry of communications can access the upload data sent by the GPS equipment which meets the national standard developed by different manufacturers. Because the protocol is the same, the platform can also forward the data to the transportation management center of provincial transportation department. At present, for buses and dangerous goods transport vehicles that need to be on the road, two passengers and one danger for short, it is required to install GPS in line with the national standard. If the transport carrier does not have its own software platform, it can use the client software of the Transportation Management Bureau and access to the transportation management center for monitoring. The charging is also a burden for enterprises. Now the national standard for GPS terminal equipment has been further extended, which requires that the reader with fingerprint and other identification must be added, and the cost is not low. After the platform software developers and GPS equipment developers install the standards, they need to pass the Ministry of transportation's detection and certification. Only after obtaining the Ministry's certification can they participate in the bidding of software and hardware. The function test of the platform by the Ministry of communications is mainly to simulate the GPS terminal sending standard protocol data, and then test whether the data can be correctly received. GPS application developers must understand and master these protocols. The platform protocols mainly include JT / tb808, 809 and extended supplementary protocols. At the same time, the protocol also applies the GB 19056 standard issued by the Ministry for the dash cam part. Therefore, all these should be seen. JT / t796 is mainly the standard of hardware equipment, which can be referred to.
