Error-proofing architecture of high-speed industrial camera firmware and control method thereof

Abstract

The invention discloses an error-proofing framework of high-speed industrial camera firmware and a control method thereof. A core processing chip of the industrial camera is connected with an ROM forfirmware storage. The method is characterized by comprising the following steps; the core processing chip is connected with an EMMC through an EMMC interface; a first Flash ROM (Read Only Memory) which is conventionally used and a second Flash ROM which is standby are connected through an SPI (Serial Peripheral Interface); wherein a partial space used for storing and updating firmware informationCheck SUM of the two Flash ROMs is cut in the EMMC, and a physical switch which is selectively communicated is connected between the core processing chip and the two Flash ROMs. By applying and implementing the mistake-proofing architecture and the control method thereof, through the principle improvement of firmware storage redundancy, the current equipment damage risk can be improved, it is ensured that the equipment firmware damage probability is extremely small, equipment replacement is avoided, and the equipment maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the field of high-speed industrial cameras, in particular to a system and a control method related to improved operation based on a firmware storage scheme. Background technique [0002] The application scenarios of high-speed industrial cameras have high requirements on the environment, such as large difference between high and low temperature, complex magnetic field changes, and severe vibration. Therefore, the life of industrial cameras will be affected to a certain extent, and the maintenance of industrial equipment has brought great challenges to engineers. At the same time, once industrial equipment starts to work, it is usually required to continue to operate without failure, but there are inevitable probabilistic equipment repairs and maintenance, and even if the equipment is replaced, the cost investment faced is huge. It should be noted that the high-speed industrial camera is only a vague name for the image ...

AI Technical Summary

Problems solved by technology

In industrial and above application scenarios, the stored firmware parameters change in real time, so the loss of parameters means a huge loss, and it is also irreversible. The continuity of the device status cannot be achieved, which does not meet the actual application requirements.
