Detailed description of the invention
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 1 is the matching system structured flowchart according to the embodiment of the present invention one, and as shown in Figure 1, this matching system comprises: tester for water ratio 10 and host computer 30.Wherein, tester for water ratio 10 is connected with host computer 30 or is coupled.
Tester for water ratio 10 is for measuring the moisture content of concrete aggregate to be produced; By the actual proportioning of the aggregate that adopts and water when host computer 30 produces concrete for calculating according to the moisture content of aggregate measured and default standard proportioning.
In existing production model, because water content of sandstone can change with Changes in weather and accumulation degree, therefore each production all needs laboratory technician to carry out the measurement of moisture content, thus adds the amount of labour.And in the present embodiment, by the moisture content of on-line measurement concrete aggregate to be produced, realize the automatic conversion of standard proportioning to actual proportioning, and then reach the effect reducing workload and enhance productivity.
Fig. 2 is the matching system structured flowchart according to the embodiment of the present invention two, and as shown in Figure 2, this matching system comprises: tester for water ratio 10, programmable logic controller (PLC) 20 (PLC), host computer 30, electric control circuit 40 and Executive Module 50.Programmable logic controller (PLC) 20 also comprises: AD conversion module 22, conversion module 24 and production control module 26.Host computer 30 also comprises: computing module 32, human-computer interaction module 34, display module 36 and output module 38.
Tester for water ratio 10, for the moisture content of on-line determination concrete aggregate to be produced, exports moisture content to PLC 20 as electronic signals; The signal of telecommunication from tester for water ratio 10 is converted into the moisture content of aggregate by PLC 20, and exports moisture content parameter to host computer 30; Host computer 30 according to the moisture content of aggregate and default standard proportioning calculate produce concrete time by the aggregate that adopts and the actual proportioning of water.
Wherein, tester for water ratio 10 is connected to programmable logic controller (PLC) 20, and programmable logic controller (PLC) 20 is also connected with electric control circuit 40 with host computer 30 respectively, and Executive Module 50 is connected to electric control circuit 40.Communication between them can adopt the mode of Ethernet.
The operating process between each various parts is described in detail below in conjunction with Fig. 2.
Tester for water ratio 10 is mounted to aggregate bin place, when producing at every turn, automatically can both be measured the moisture content of every storehouse material by tester for water ratio 10, achieve real-time online and accurately measure.
The AD conversion module 22 that the data that tester for water ratio 10 is recorded send into PLC20 with the current signal of 4-20mA carries out analog-to-digital conversion, convert through the inside of conversion module 24 and draw the actual percentage of water content of sandstone, be i.e. the percentage of the corresponding moisture content of input current signal.Such as, when input current signal is 4mA, moisture content is 0%, and when input value is 20mA, moisture content is 100%; When input value is 12mA, moisture content is 50%, and size of current is corresponding with moisture content linearly proportional.
By the actual moisture content recorded, send into host computer 30 via ethernet communication, too increase the real-time Presentation Function of moisture content simultaneously at the monitoring interface (display module 36) of host computer 30.In the present embodiment, host computer display module 36 can show the real-time condition of production and each controling parameters, and can show again the actual percentage of moisture of sandstone, working condition is very clear, reach the state of man-machine interface close friend, make the working condition of the understanding whole system that operator can be real-time.
Host computer 30, by after reading the moisture content sent here of PLC20, is converted to existing laboratory standard proportioning by computing module 32 on backstage, draws actual proportioning value.
Its corresponding proportioning transfer algorithm is as follows, and principle is the multiplication computing formula based on moisture content:
Sandstone inventory=sandstone proportioning × (1+ moisture content)
Water inventory=water proportioning-sandstone inventory × moisture content
Namely, after tester for water ratio records the moisture content of sandstone, actual sandstone inventory can corresponding increase, while corresponding minimizing proportioning in the inventory of water.
Such as: the stoichiometric(al) of setting laboratory to provide is as sand 200Kg, water 100Kg, and the actual moisture content recording sand is 10%, then can be obtained by above-mentioned reduction formula:
Actual sandstone inventory=200 × (1+10%)=220Kg
Actual water inventory=100-220 × 10%=78Kg
After obtaining the proportioning value after conversion, the up-to-date proportioning parameter of host computer 30 Lookup protocol, sends up-to-date producting proportion parameter instruction by output module 38 to PLC20, and PLC20 activates and starts corresponding control program simultaneously.
PLC20 exports production control signal to electric control circuit 40 by programme-control by production control module 26, controls Executive Module 50 realize automatic production via electric control circuit 40.Because electric control circuit 40 and Executive Module 50 all belong to prior art, be not explained in detail at this.
In the above-described embodiments, the human-computer interaction module 34 by host computer 30 inputs relevant parameter and instruction, such as, and the parameters such as standard proportioning.Certainly, after the real time data that tester for water ratio 10 measures, the moisture content that operator can record according to analyzer carries out manual parameters setting by human-computer interaction module 34, thus obtains the proportioning after changing, and typing job order is produced.
By above-described embodiment, the accuracy of proportioning can be realized, both reached real-time, in turn ensure that the Performance and quality of product.
