Description
Technical field
The present invention relates to a kind of instrument experimental system, is a kind of bus type instrument experimental system specifically, particularly a kind of multi-protocols reconfigurable bus formula instrument experimental system.
Background technology
Along with the technological transformation of a tobacco business new round, all kinds of process instruments of workshop and energy branch works mainly adopt bus communication mode to carry out the transmission of data and meter information, according to the situation of current all kinds of process instrument statistics, the protocol type of supporting is various, has Profibus-PA, Profibus-DP at present at the bus protocol of use, ProfiNet, FF foundation fieldbus, MODBUS, Industrial Ethernet.
Replacing, the cycle calibration of industry and enterprise measurement technology personnel to this class instrument is very puzzled, cannot realize the independent metrological operation of instrument, and under environment, carry out calibration at the scene, has many site environment uncertain factors.Owing to there is no supporting self contained instrument system support, cannot realize the parameter setting of spare part instrument and the replacing of problem instrument simultaneously.Set up this system and can effectively break away from the restriction of instrument producer to instrument corollary system, grasp meter performance and the transmission of understanding bus type agreement comprehensively, configuration, configuration, has great practical value.
Summary of the invention
In order to solve above-mentioned technical matters, object of the present invention provides a kind of multi-protocols reconfigurable bus formula instrument experimental system, not only can realize bus type intelligent instrument (being comprised: Profibus-PA, Profibus-DP, ProfiNet, FF foundation fieldbus, MODBUS, Industrial Ethernet) parameter be configured with measurement data and show, and can also be in the time changing the instrument system of different bus type, do not change system software programming, only need change system hardware configuration, realize software and hardware farthest multiplexing.
In order to realize above-mentioned object, the present invention by the following technical solutions:
A kind of multi-protocols reconfigurable bus formula instrument experimental system, this system comprises man-machine interface, PLC hardware system and reconfigurable intelligent instrument system, described PLC hardware system comprises power module, CPU module, ethernet module, DI/DO module and AI/AO module, described man-machine interface is communicated and is connected with described PLC hardware system by ethernet module, described reconfigurable intelligent instrument system comprises analog quantity instrument system, MODBUS TCP instrument system, Profibus-DP instrument system, Profinet instrument system, FF instrument system and Profibus-PA instrument system, analog quantity instrument system is communicated and is connected with described PLC hardware system by AI/AO module, MODBUS TCP instrument system is communicated and is connected with described PLC hardware system by ethernet module, Profinet instrument system is communicated and is connected with described PLC hardware system by CPU module, Profibus-PA instrument system communicates and is connected with described Profibus-DP instrument system by DP/PA coupling mechanism and DP/PA connector are set, FF instrument system communicates and is connected with described Profibus-DP instrument system by DP/FF coupling mechanism and DP/FF connector are set, described Profibus-DP instrument system is communicated and is connected with described PLC hardware system by CPU module.
Multi-protocols reconfigurable bus formula instrument experimental system of the present invention, it (comprising: Profibus-PA bus type intelligent instrument by realizing, Profibus-DP, ProfiNet, FF foundation fieldbus, MODBUS, Industrial Ethernet) access the bus protocol instrument system of all kinds of supports, data (comprise power module through the PLC system of building, CPU module, ethernet module, analog quantity (AI/AO) module, digital quantity (DI/DO) module), each module is connected by core bus, realize parameter configuration and the data display function to all kinds of instrument by man-machine interface.This invention is in the time changing with agreement experimental subjects, without the programming of change system software, only need change system hardware configuration, can realize software and hardware farthest multiplexing, realize the interchangeable of bus type instrument, thereby avoid, because the change of system upgrade or testing requirement causes software overprogram, greatly increasing the dirigibility of system, reduce the development time.
