Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The invention proposes a multi-type industrial Ethernet bus integrated master station and a method for realizing parallel work of the multi-type industrial Ethernet bus. In the same master station device, the hardware structure of multiple microprocessors plus FPGA (Field Programmable Gate Array, that is, Field Programmable Gate Array) can be used to realize multi-type industrial Ethernet bus master stations without changing any hardware. The integration of functions, and the parallel work of multiple types of industrial Ethernet bus functions are realized by sharing interrupts and memory, w...

Abstract

The invention discloses a multi-class industrial Ethernet bus integrated master station which comprises a core processor, a system bus interface module, n twin-port data storage devices, an interrupt signal processing module, n micro-processors, n network chips and n network interfaces. According to the multi-class industrial Ethernet bus integrated master station, in the same bus master station equipment, under the condition that no hardware is changed, integration of the multi-class industrial Ethernet bus master station functions can be achieved, and concurrent working of the multi-class industrial Ethernet bus master station functions is achieved, and thus in the same bus master station equipment, different industrial Ethernet bus master station equipment can access the bus master station equipment simultaneously, the different bus master station equipment can be compatible and work concurrently in a same set of system, and consequently technical barriers between different industrial Ethernet bus protocols are broken easily, the problem that various kinds of bus equipment can not be compatible is solved, the extensibility of the sub system is improved, and the configuration requirements of diversification and interchangeability of bus system users are satisfied.

Description

technical field [0001] The invention belongs to the technical field of field bus, and specifically relates to a multi-type industrial Ethernet bus integrated master station and a method for realizing parallel work of multi-type industrial Ethernet buses, which can be used in various automatic control systems. Background technique [0002] Industrial Ethernet bus technology is one of the most important, fastest-growing and most widely used branches in the field of field bus technology. The industrial Ethernet bus adopts the standard Ethernet physical layer and has the ability to transmit various signals in high-speed, real-time and fully digital. , has been widely used in various types of automatic control systems. However, there are many kinds of international standard industrial Ethernet bus protocols at present, and various industrial Ethernet bus protocols are not compatible with each other. At present, the same types of products (such as servo drives, I / O devices, etc.)...
