Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the accurate weighing and dispensing system of one of the present utility model, there is many material feedings system 1, data handling system 7, two overlaps Weight acquisition system (3,5) and two cover batching control centring systems (4,6), described many material feedings system 1 has material outlet, and described material outlet is positioned at above weighing bucket 12; Often overlap Weight acquisition system (3,5) LOAD CELLS and analog-to-digital conversion module is included, two cover Weight acquisition systems (3,5) LOAD CELLS is installed on after mutually connecting in weighing bucket 12, often overlap Weight acquisition system (3,5) signal input port of the analog-to-digital conversion module in and same set of Weight acquisition system (3,5) load cell signal connects, two cover Weight acquisition systems (3,5) signal outlet of the analog-to-digital conversion module in connects with a set of batching control centring system (4,6) signal respectively; Two covers batching control centring system (4,6) are all connected with data handling system 7 signal.Described data handling system 7 is high-speed data disposal system.
Also comprise input system 9, display system 8, storage system 10 and acoustooptic alarm system 11, described display system 8 is connected with data handling system 7 signal, and described input system 9 and storage system 10 are all connected with display system 8 signal.Described acoustooptic alarm system 11 is connected with data handling system 7 signal.
Described Weight acquisition system (3,5) comprises communication device.Described communication device is used for batching control center (4,6) and downloads material formula data from storage system 10 and feed back its blending process status signal to display system 8.
Many material feedings system is used in blending process according to batching control centring system (4,6) instruction will specify material to drop in weighing bucket 12, input system 9 is for the input of the formula of user and the instruction of equipment operation, input system 9 also can be used for lead and the speed reinforced switching point value of material in blending process, the input of alarming determining and comparison error rate scope.Material drain system 2 comprises most Constant Current Control System, evenly sends into next procedure for controllably preparing material at blowing process medium velocity.
Weight acquisition system (3,5) and batching control centring system (4,6) all have two covers respectively, and a set of is normality active configuration, and another set of is redundant configuration.Two covers Weight acquisition system (3,5) are sent into gathering after the weight simulating signal come is converted into digital signal in each self-corresponding batching control centring system (4,6).Two cover batching control centring systems (4,6) formulation data being responsible for issuing according to operating system controls many material feedings system and accurately drops in weighing bucket 12 by various materials segmentation, and weight data Weight acquisition system (3,5) gathered and the actual batching value of current material send into high-speed data disposal system 7.
High-speed data disposal system 7 needs to check weighing precision and proportioning accuracy simultaneously, weighing precision process of checking is by two cover Weight acquisition systems (3,5) digital signal inputted is compared and is drawn the error rate of weighing data, and proportioning accuracy process of checking is that actual batching value when being completed by often kind of material feeding in blending process is compared with the material allocation value issued and drawn the error rate of data of preparing burden.Drawn two kinds of error rates are drawn comparison result (namely error rate is judged to be working properly within the scope of specification error rate, exceeds error rate scope and is namely judged to be fault) with the corresponding error rate scope comparison of setting by high-speed data disposal system 7 more respectively.Finally, the result of determination after process and weight information are sent into display system 8 and storage system 10 by high-speed data disposal system 7.
The result of determination of input and weight of weighing are shown on HMI interface by display system 8, the data feeding storage systems 10 such as the actual ingredients by weight value of every batch and formula value are carried out intelligent screening storage simultaneously and inquire about to facilitate in the future.Display system 8 is also responsible for the formula table of input, before each batching starts, material formula table is issued to batching control centring system (4 by communication device, 6) in and in high-speed data disposal system 7, for burden process provides the target weight value of often kind of material and proportioning accuracy to check the check foundation of the precision of process.
As long as high-speed data disposal system 7 finds that any one error rate in two kinds of error rates judges not pass through, then send sound and light alarm signal to acoustooptic alarm system 11, in display system 8, show corresponding alarm content simultaneously, warning comprises the suggestion processing scheme of current alerts kind (weighing precision is reported to the police or proportioning accuracy is reported to the police) and corresponding warning, for maintenance personal's handling failure quickly.Corresponding progress is reported to the police once produce, and high-speed data disposal system 7 will stop the batching work of Weight acquisition system (3,5) immediately, avoid the not right material of proportioning to enter next procedure, reduces loss.Maintenance personal, after receiving the system failure, can eliminate the audible alarm of emergency alarm bell by the alarming determining button in display system 8 or on acoustooptic alarm system 11, avoid causing interference to maintenance process.When system can not keep in repair recovery very soon due to fault, system manager can judge device (the two cover Weight acquisition systems (3 that break down, 5) or Weight acquisition system (3,5) a set of in) prerequisite under, the Weight acquisition system (3 that will normally can be worked by the HMI interface of display system 8,5) normality active configuration is classified as, and allow system works to carry out weighing and burden work under single weighing operation state, such permission staff can utilize production gap to keep in repair, and does not affect manufacturing schedule.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
