Problems solved by technology

[0003] The measurement technicians of the industry and enterprises are very confused about the replacement and periodic inspection of such instruments, and cannot realize the independent measurement operation of the instruments, but can only carry out the inspection and calibration in the field environment, and there are many uncertain factors in the field environment
At the same time, due to the lack of supporting independent instrument system support, the parameter setting of spare parts instruments and the replacement of defective instruments cannot be realized

Abstract

The invention relates to a multi-protocol reconfigurable bus-based instrument experiment system. The system comprises a human-computer interface, a PLC hardware system and a reconfigurable intelligent instrument system. The PLC hardware system comprises a power module, a CPU module, an Ethernet module, a DI / DO module and an AI / AO module. The human-computer interface is in communication connection with the PLC hardware system through the Ethernet module. The reconfigurable intelligent instrument system comprises an analog quantity instrument system, a MODBUSTCP instrument system, a Profibus-DP instrument system, a Profinet instrument system, an FF instrument system and a Profibus-PA instrument system. The multi-protocol reconfigurable bus-based instrument experiment system can achieve the purpose that software and hardware are reused to the largest extent and achieve interchange of bus-based instruments, so that the fact that the software is repeatedly programmed due to system upgrade or test demand changing is avoided, the flexibility of the system can be greatly improved, and development time is reduced.

Description

technical field [0001] The invention relates to an instrument experiment system, in particular to a bus-type instrument experiment system, in particular to a multi-protocol reconfigurable bus-type instrument experiment system. Background technique [0002] With the new round of technological transformation in the tobacco industry, various process instruments in production workshops and energy auxiliary workshops mainly use bus communication to transmit data and instrument information. According to the current statistics of various process instruments, there are various types of protocols supported. The bus protocols currently in use include Profibus-PA, Profibus-DP, ProfiNet, FF Foundation Fieldbus, MODBUS, and Industrial Ethernet. [0003] The measurement technicians of industrial enterprises are very confused about the replacement and periodic inspection of such instruments. They cannot realize the independent measurement operation of the instruments, but can only carry ou...
