| Abstract: | This article introduced a kind of interface scheme applied to interlinkage of petroleum downhole tools is introduced, and inerlinkage model based on controller area network is put forward. The controller area network module available on digital signal processor is the fundamental element, whose software consists of initializing controller area network module, receiving data, sending data and management of mailbox interrupts. Testing show that the design has high reliability and real-time ability, and call satisfies requirements of control and data transfer of petroleum downhole tools. |
