Abstract
The electronic balance and microcomputer combined application method for analysing electric signal of fuel, raw material or other sample, collecting data and transfering the data into microcomputer is characterized by that its microcomputer host possesses three kinds of matched drivers, and its program development is designed with three user programs of data acquisition,data management and system management, and the system management program possesses an extended virtual hard disk D in its internal storage, the user program can be copied on the hard disk D, and a data base is established, after a data access process is completed, said data can be stored in disk C and disk A, and after the whole analytic work is completed, the data can be transfered to disk B, and used as information record.
Description
The present invention is used for the analysis to the ash of fuel, raw material or other samples, fugitive constituent, moisture content or other compositions, is particularly useful for the new method to the technical analysis of coal and coke.
At present, in the technical analysis of coal and coke, be to adopt GB GB-212-77 to measure to the mensuration of ash, fugitive constituent, moisture content etc. always.Its assay method is manually accurately to take by weighing 1g (accurate to 0.0002g) coal sample, in temperature is to obtain ash after the calcination under 815 ± 10 ℃ the condition, and the percentage that residue weight accounts for the former weight of sample after the ashing is the percentage composition of ash.Fugitive constituent is meant that coal in the heating of high temperature secluding air, decomposes, with vaporous that a part of combustible of separating out of gas under regular hour and temperature.The method has the human factor of very big composition in measuring the slow and weighing process of process medium velocity, cause error to strengthen the cumbersome again fallibility of calculation procedure.
The objective of the invention is to provide a kind of new method that is used for coal and proximate analysis of coke, can increase work efficiency and obtain result accurately, avoid the influence of human factor in the weighing process.
The present invention realizes as follows:
With electronic balance and microcomputer coupling, sample is transformed into electric signal, report is handled and be printed as to data.But electronic balance has the charactron video data, has the RS-232 communication interface to connect with microcomputer.The microcomputer of selecting for use, main frame are accepted operating personnel instruction, then according to the data of instruction acquisition electronic balance or carry out data processing; Microcomputer monitor is selected 718 * 1024 high-resolution color monitors for use, adopts the screen prompt operation in the design, and each step of analyzing is all pointed out.Keyboard is selected 101 type universal keyboards for use, for operator's input instruction and data.Printer is selected the printer of LQ-1600K band Chinese character base, output report for use.The establishment of program is provided with the user program of three kinds of functions: the one, and data acquisition program, the 2nd, data administrator, the 3rd, system supervisor.The electronic balance parameter is arranged to the flowing water method of operation, ceaselessly transmits the weight data of sample by the RS-232 communication interface, and before data titled with stable and astable mark.Microcomputer employing BASIC is implemented the communication with electronic balance, just its form with text is preserved after receiving the data that have stable labelling, imports data administrator then.Data administrator adopts DBASE-III Database Systems, and total system is divided into a MAIN primary module and seven submodules, E, F, G, H, I, J, K.E: database is founded; F: working sample moisture content; G: working sample ash; H: working sample fugitive constituent; I: data operation; J: sample moisture content; K: printed report is single; L: withdraw from.Primary module implements screen design and function menu shows, starts the various functions of primary module screen prompt and selects for the operator.The operator by the function corresponding key, and can enter the function corresponding submodule according to prompting.System supervisor, main frame are furnished with A, B, three kinds of starters of C, and the B dish is exclusively used in storing history data, and one month once, periodic replacement.A dish and C have taken inventory driver and user program, use the C dish usually, and the A dish is made hot storage dish.The disk workload is big because The whole analytical process deposits, withdraws, and a day accessing disk number reaches several thousand times more than, so operation is infeasible on floppy disk or hard disk, so work out a cover system supervisory routine, starts computer system at every turn, and supervisory routine just starts voluntarily.This system supervisor at first at virtual hard disk D of memory expansion, copies user program on the virtual hard disk D to then, and sets up database on the D dish.Because the D dish is actually the Installed System Memory district, access does not have the action of magnetic head, and is not only safe and reliable, and access speed is very fast.Pending data access computing finishes, and deposit data is coiled to C dish and A again, in case have a power failure data is washed out.After class's analytical work finishes, again data are moved on to the B dish, give over to historical summary, analyze for the parties concerned and use.
The present invention is used for the technical analysis of coal, coke, and speed is fast, and the result is accurate, can satisfy sample analysis in enormous quantities, alleviates labor intensity of operating staff, and can adapt to the variation adjustment running parameter of site environment, guarantees to analyze the quality of data.
Fig. 1 constitutes synoptic diagram for the present invention.
Fig. 2 is a software flow block diagram of the present invention.
The present invention is described in further detail below in conjunction with accompanying drawing 1:
Electronic balance (1) is converted into electric signal to example weight through RS-232 communication interface input main frame (2).Operating personnel, import printer (5) and print analysis report with keyboard (4) input instruction and data according to the prompting of display (3) after the microcomputer calculation process.
