Protocol converter instrument remote configuration method

Abstract

The invention discloses a protocol converter instrument remote configuration method, which comprises the following steps that a configuration tool for an appointed CAN instrument protocol is provided,and a configuration file is output; an operation and maintenance engineer inputs data items in a CAN instrument protocol needing to be docked and outputs a configuration file in a specified format through a page or a configuration program, and the file comprises configuration attribute data of each data item needing to be issued; the configuration file can trigger the vehicle-mounted machine to the ftp server through a command to formulate path downloading and import the path downloading into the vehicle-mounted machine through the USB flash disk, and the ftp server downloads a command to bereported to the scheduling platform to receive a response; the vehicle-mounted machine downloads the configuration file to a protocol converter in a data stream mode for local storage and then deletesthe configuration file; and the vehicle-mounted machine sends the uploading sub-message sending interval of each period to the protocol converter local machine for storage through a protocol. The invention provides an instrument protocol docking scheme which can achieve the purposes of flexibility, unification and scientific management, remote configuration management can be achieved, configuration work is executed by an operation and maintenance department, repeated work of a research and development department is reduced, maintenance work becomes simple, and the purpose of improving the efficiency of research and development of human resources is achieved.

Description

technical field [0001] The invention belongs to the technical field of meter configuration equipment for public transport vehicles, and in particular relates to a remote configuration method for a protocol converter meter. Background technique [0002] In recent years, bus users have purchased vehicles and proposed to use intelligent dispatching terminals to collect vehicle instrument bus data and upload them to the intelligent dispatching platform. The current hardware connection scheme mainly uses protocol converters as intermediate acquisition devices to connect the vehicle CAN bus and vehicle dispatching terminals. . Up to now, our company has connected many instrument buses such as Intrinsic Safety, Okejia, Weidi, Sherryman, Jingyida, Hannasen, etc. With the gradual increase of new energy vehicles, new energy related data are also connected more and more. Summarizing the data formats of various instrument manufacturers, the content and expression methods of different ...

AI Technical Summary

Problems solved by technology

With the continuous increase of docking protocols, new data items will continue to be added at the end of the sub-message, resulting in a continuous increase in the length of the sub-message, resulting in more and more waste data uploaded to the platform;

[0007] 2. Every time a new bus protocol is received, it is necessary to confirm the version that conforms to the protocol and can be used from many protocol converter programs

If it cannot be retrieved, it is necessary to arrange engineers to carry out development and verification tests, and at the same time increase the flow of processes in each link, resulting in a large increase in human resource costs including testing links and release links;

[0008] 3. Affect the normal use of customers

When the agreement is obtained, it is often faced with the delivery of equipment, and the equipment has been installed on site before the program is released, causing customers to be unable to use it in time, and increasing the workload of program updates and maintenance in the future;

[0009] 4. The program version is not uniform and difficult to manage

The reason is that with the increasing number of protocols, the software versions of the protocol converter program are also increasing, which increases the difficulty and time of retrieval, making version management more and more difficult
