Description
Technical field
The utility model belongs to the measuring instrument field, and the functional structure that relates in particular to measuring instrument improves.
Background technology
Measuring instrument in the market is multifarious, but an identical point is arranged, basically all be to adopt surface-mounted integrated circuit, the communication interface that provides be RS485 RS232.Its total shortcoming is as follows: the one, RS485 the communication speed of RS232 slower; The 2nd, communication modes is with robotization bus (PROFINET) and the fieldbus (PROFIBUS) of the Industrial Ethernet technology of main flow are difficult to directly dock at present; The 3rd, relatively poor antijamming capability will cause larger error to the precision of metering, cause measuring accuracy to descend; Four is that an instrument can only be controlled a metering outfit, has increased measuring cost, has also caused the wasting of resources; The 5th, its maintenance difficult, assembly technology is complicated; The 6th, the database function of existing measuring instrument is poor, can't realize historical query data and report capability.
Summary of the invention
The utility model is exactly for the deficiencies in the prior art, a kind of intelligent metering instrument is provided, thereby it can improve communication speed, realizes the Direct Communication of instrument and PROFINET/PROFIBUS, strengthen antijamming capability raising measuring accuracy, and can realize that an instrument is to the control of many metering outfits, the inquiry of historical data and the report capability of realization instrument; Especially it has been simplified assembly technology, has saved time and cost, easy to maintenance convenient.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises a cabinet, its structural feature is: integrated installation has the CPU module in the cabinet, instrument, communication module, signal processing module A, signal processing module B, power module of voltage regulation, signal anti-interference process module, display module, the multi-point detection module, after instrument starts, enter after the metering signal source process signal anti-interference process resume module of instrument to collect and carry out the signal processing among the signal processing module A, metering signal after signal processing module A will process feeds back to the CPU module, the CPU module calculates the metering result according to metering signal, and regulate according to the result who the calculates pair metering outfit that is connected with the multi-point detection module, display module and the two-way control linkage of CPU module, communication module provides PROFINET or PROFIBUS communication interface for instrument, and the multi-point functional module is the be connected control of realization separate unit instrument with many metering outfits; The database function that CPU provides can be realized historical query and the report capability of instrument.Preferably, a series of processing is isolated, amplifies, changed to the signal immunity module to the signal source of analog signals processing module; In order to greatly strengthen the antijamming capability of instrument.
Further optimize, display module is one of touch-screen or PC.
Preferably, the metering outfit that is connected with the multi-point detection module is that belted electronic balance, spiral claim, rotor weigher,
At least a in blk weigher, impact flow meter, the weighbridge.
The utility model beneficial effect:
The one, the utility model adopts modular structure, and assembling is simple, and the time spent is few, for in the future maintenance and maintenance job brings great convenience, certain functional block breaks down in the future, directly its replacing is got final product, and has avoided that other instrument are out of joint will change the cost waste that instrument brings; The 2nd, PROFINET/PROFIBUS provides very easily interface, makes the control of instrument and the management of data enter very easily the DCS system; Three is that an instrument can be to the separate unit metering outfit, control such as belted electronic balance, bucket type blanking scale, helix balance, rotor weigher, impact flow meter etc., also can control many metering outfit of the same race, can also control many metering outfit not of the same race; The 4th, the utility model can not only be controlled metering outfit, and various controls can also be provided for the equipment except metering outfit and detect interface; The 5th, its communication speed is accelerated, and data-handling capacity strengthens, and powerful report capability can be inquired about the historical data of in the past any time section.
