Abstract
The present invention relates to a new method for combining an electronic balance with a microcomputer, which is suitable for analyzing electric signals of fuels, raw material or other samples, collecting data and transmitting the data to a microcomputer. A host microcomputer is provided with three drivers; three user programs, namely a data collection user program, a data management user program and a system management user program, are designed for programming; the system management user program expands a virtual hard disk D in a memory; the user programs are copied to the virtual hard disk D, and a database is created; after data access is finished, data is stored to a C disk and an A disk; after work is completed, the data is transferred to a B disk and used as information records.
Description
The present invention is used for ash, fugitive constituent, the moisture analysis of fuel, primary product, is particularly useful for the 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 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 is that following mode realizes:
With electronic balance and microcomputer coupling, sample is transformed into electric signal, report is handled and be printed as to data.But electronics has the charactron video data flat, has the RS-232 communication interface to connect with microcomputer.Microcomputer is 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 the 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, microcomputer 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.Because the The whole analytical process preface, to get the disk workload big, 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, not only safe and reliable, and access speed is very fast, and pending data access computing finishes, again deposit data is coiled to C dish and A, in case the power failure data are 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 and fails and main frame (2) through the RS-232 communication interface.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.
The electronic balance that the present invention adopts and the microcomputer method and the conventional GB method ash contrast test data of microcomputer coupling see Table one.
