Camera traffic and MES services share the same network and can easily affect each other. This article explains the difference in performance between packet loss and delay during mixed running, and the three levels that separate the visual network and the MES network.

With the same nominal rating of 10 Gigabit, the actual performance of the acquisition host network card is quite different. This article explains the judgment basis for visual workstation selection from three perspectives: main control chip, slot negotiation bandwidth, and interrupt queue settings.

The machine vision station must not only supply power to the camera and light source, but also run data. If the power supply and wiring are not planned well, it is easiest to rework. This article summarizes the main points of power supply location, strong and weak current slots, and downlink protection.

When the production line network loses packets and suspects the equipment, it is often in vain. This article gives a three-step troubleshooting sequence to distinguish between frequency converter interference, line quality and equipment problems, as well as the true applicable boundaries of copper-to-optical conversion.

Quality inspection images need to be fed to MES and on-site judgment at the same time. How can the network and local cache be combined to prevent data loss? This article summarizes the upload path, network disconnection caching strategy, and storage expansion ideas for the workstation host.

Converting camera pixels and frame rates into actual link requirements is the first step in deciding between Gigabit and 10 Gigabit access. This article gives the calculation of aperture, the role of large frame length, and the respective applicable distances of electrical ports and optical ports.

When reporting instrument data from university and hospital laboratories, a common pain point is packet loss and misalignment of recording times. This article provides certain planning standards from three aspects: isolation of instrument network and office network, unified clock, and single-fiber or dual-fiber cabling at the end.

Campus network upgrades are often stuck in the links and wiring resources between buildings, rather than the old and new switches. This article gives a three-step sequence: first measure the light reception margin direction by direction, then calculate the connection bandwidth according to the dormitory night peak value, and finally reserve enough trunk core cores and distribution frame ports at one time.

Standardized test sites need to stably transmit examination room images, sound pickup and PTZ access control back to the center. The school's original network cable is often limited by distance. This article focuses on three parts: channel inventory, single-fiber core saving, and reverse 485 wiring to provide comparison points before the transformation and construction of the test site.

The selection of the link for recording and broadcasting lessons determines whether to rework it later. This article gives a comparison based on three lines: baseband signal or network code stream, multi-mode or single-mode transmission distance, and the number of two-way channels required in the control room, and explains which classroom scenarios the non-compressed optical transceiver is suitable for.
