Description

Technical Field

[0001] This invention relates to the field of hydrogen production equipment technology, and in particular to a method for writing and printing data on hydrogen production equipment, a writing and printing system, and a hydrogen production system. Background Technology

[0002] In existing technologies, remote rewriting solutions for hydrogen production equipment (Electronic Control Unit, ECU) have the following drawbacks: Firstly, most solutions centralize firmware flashing protocol processing and flashing logic on cloud servers. Public network transmission delays and jitter can severely interfere with the strict timing requirements of firmware flashing messages, easily leading to flashing process timeouts and failures, resulting in very poor stability.

[0003] Secondly, existing solutions are mostly fixed software, which is difficult to adapt to the specific flashing streams or diagnostic needs of different ECUs. When the flashing strategy needs to be updated, the entire cloud platform needs to be upgraded, which is a complex process and slow to respond.

[0004] Thirdly, security measures often focus only on the application layer (such as secure access during firmware flashing) or the transport layer (such as Hypertext Transfer Protocol HTTPS), lacking a defense-in-depth system. Once a single security mechanism is breached, the entire system faces risks.

[0005] Fourthly, the entire process involves transmitting a large number of firmware flashing requests, response raw messages, or firmware data via remote connection, which consumes a lot of bandwidth and is inefficient.

[0006] Therefore, it is necessary to provide a novel brushing method, brushing system, and hydrogen production system for hydrogen production equipment to solve some of the aforementioned problems existing in the prior art. Summary of the Invention

[0007] The purpose of this invention is to provide a method, system, and system for flashing firmware for hydrogen production equipment, thereby improving the stability of firmware flashing for hydrogen production equipment.

After receiving the response information from the hydrogen production equipment in response to the verification request information, the field edge management unit enters the reset process and then sends the reset request information to the hydrogen production equipment. After receiving the response information from the hydrogen production equipment in response to the reset request information, the field edge management unit sends the write result information to the data transmission unit. The data transmission unit receives the flashing result information, then encrypts and transmits the flashing result information to the cloud management unit.

[0013] This invention also provides a flashing system, including a cloud management unit, a data transmission unit, and a field edge management unit. The cloud management unit and the data transmission unit, as well as the data transmission unit and the field edge management unit, are communicatively connected.

After receiving the flashing task instructions and the flashing firmware data, the field edge management unit calls a locally stored flashing script, triggers the flashing process of the hydrogen production device according to the flashing task instructions, and then flashes the flashing firmware data into the hydrogen production device according to the flashing process.

[0014] Optionally, the field edge management unit includes a programming session request information sending module, a key sending module, a memory erase information sending module, and a firmware data writing module. The programming session request information sending module is used to send programming session request information to the hydrogen production device during the programming session process.

[0018] The beneficial effects of this invention are as follows: the cloud management unit is only responsible for issuing flashing task instructions and flashing firmware data. The data transmission unit transmits the flashing task instructions and flashing firmware data to the field edge management unit, which then flashes the flashing firmware data into the hydrogen production equipment via the local network. This eliminates the need for the cloud management unit to directly flash the flashing firmware data into the hydrogen production equipment via an unstable public network, thus improving the stability of the flashing process. The cloud management unit only communicates once through the data transmission unit, resulting in a highly efficient process with extremely low bandwidth consumption. The data transmission unit processes the flashing task instructions and flashing firmware data... Encrypted transmission is implemented, and the cloud management unit communicates with the field edge management unit only through the data transmission unit, achieving mandatory isolation and encryption of network access. The field edge management unit calls the locally stored flashing script to complete the flashing process. Updating the flashing script directly can adapt to different models of hydrogen production equipment without upgrading the entire cloud management unit, realizing the possibility of "one-time deployment, unlimited expansion". The field edge management unit flashes the flashing firmware data into the hydrogen production equipment through the local network. The data of the flashing process does not occupy the bandwidth of the public network, which greatly reduces the bandwidth utilization rate and avoids the latency of the public network, ensuring the strict timing of the flashing process.

Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed following the word and its equivalents, but do not exclude other elements or objects.
