Description of drawings
Fig. 1 is a system architecture diagram of the present invention.
The specific embodiment
A kind of ventilation forecasting and early-warning system for mine; The auxiliary computing system of resolving as ventilation network; As shown in Figure 1; Comprise the SQL database that is used for store data, data file generation module, ventilation forecast budget module and output module as a result, said data file generation module is used to receive all kinds of parameters that ventilation network resolves that are used for of designer's typing, when receiving the data typing, data is carried out the check of form and number range; Said ventilation forecast budget module is used to accomplish the various calculating that mine ventilation network resolves; Be the nucleus module of said ventilation forecasting and early-warning system for mine, its result of calculation comprise mine ventilation network and wherein each bar divide air quantity, resistance and the pressure of branch air duct and ventilating fan; Said output module as a result is used for the output to the calculation result data of said ventilation forecast budget module, comprises air quantity, blast and windage and equivalent orifice; The result of calculation of data that said data file generation module received and said ventilation forecast budget module all deposits said SQL database in, and the former is by said ventilation forecast budget module invokes, and the latter is called by said output module as a result.
Said data file generation module comprises data input submodule and data edition submodule, and said data input submodule only is used to said SQL database and creates the raw data file that resolves; Said data edition submodule is used for the data of said raw data file are made amendment, with adjustment Design of ventilation scheme.
The said data input data that submodule received are divided into two types; Be network basic parameter and network characterization parameter; Said network basic parameter comprises the title of mine, scheme, the total amount of branch, node and blower fan, the fixedly numerical value of air quantity number and natural ventilation pressure number; These all are the values to the global variable of a certain design scheme, also comprise being used to characterize the precision of resolving the result and iteration precision and the maximum iteration time of finding the solution speed.
Said network characterization parameter is used for characterizing the characteristic of the blower fan that network type, ventilation characteristics and network be provided with, and relates to some design parameters of preliminary project.Said network characterization parameter comprises the network raw data that contains roadway shape in each branch, position, ventilation type feature, the natural ventilation pressure data that contain the fan characteristic data of the characteristic parameter that characterizes ventilating fan and contain the natural ventilation pressure parameter of each branch.The typing process of network characterization parameter has promptly embodied the process of preliminary design, and system one by one sets each parameter value according to the design cycle guide designers of routine, has saved the time that the designer browses chart, and the unit of should be noted that chooses in the data typing.
This prediction early warning system is applicable to multiple roadway shape and multiple ventilation type, and calculates to the internal portion of different roadway shapes and ventilation type and to encapsulate, and as long as the designer is the attention correct selection.In this example, said roadway shape comprises: trapezoidal, semicircle arch, Samsung arch or circle, and said ventilation type comprises: the passageway that generally ventilates (comprising chamber); Transporter lane, air entering and returning lane, exploiting field, coal-face, stone drifting work plane; Coal (half coal petrography) lane driving face, up-down material pit shaft does not have the ventilating shaft of lifting or wind cave; Main air entering and returning lane, up-down personnel pit shaft, stringing electrical locomotive lane, air crossing.
In the data typing process, system also can provide corresponding essential design parameters input prompt, and guiding user design, selected parameter in time feed back error message, and prompting is revised.
After having accomplished ventilation forecasting and early-warning system for mine and dividing the establishment and edit-modify that wind resolves raw data file, just can get into ventilation forecast budget module and the branch wind of having set up resolved raw data file ventilate forecast budget.Ventilation forecast budget module is the nucleus module of ventilation forecasting and early-warning system for mine; Its internal calculation is the groundwork of native system; Outside design operation seldom; If resolve to the data file of having set up, then directly to carry out " dividing wind to resolve " order and get final product, native system also provides the function of calling external data; Promptly can calculate said external data and be directed against resolving the result and all can being saved in the SQL database automatically of its through carrying out the prediction of ventilating of formatted data outside the said SQL database of " importing external data " command calls with early warning.
Be provided with two big generic modules in the said output module as a result; One type is the prediction output sub-module, is used for the output of resolving the result of each branch of ventilation network, and another kind of is early warning branch output sub-module; The implementation method of this two generic module comes down to identical; All be to resolving all or part of output of result data, different is to different focus, its querying condition and result field choose difference to some extent.
The way of output of prediction output sub-module has the querying condition of employing and the result field customization way of output and resolves the full way of output of result data; Wherein customize the way of output and be divided into coal-face prediction output sub-module, the driving face prediction output sub-module that the ventilation type is respectively coal-face branch and driving face branch according to querying condition; Branch pattern is the fixing fixedly air quantity branch prediction output sub-module of air quantity branch; The blower fan actual parameter prediction output sub-module of output blower fan actual condition is weighed the equivalent orifice of ventilation effect and is predicted output sub-module.
Early warning branch output sub-module; Be used to export its resolve the result do not meet designing requirement branch resolve the result; These situation that do not meet designing requirement comprise: wind speed transfinites, deficiency in draught or inverted air current, and every its relevant result that resolves of branch of above-mentioned situation that exists all exports in this module.Because what this way of output adopted also is the customization way of output, and institute might in-problem branch all be shown, and has made things convenient for designer's inquiry.
Said output module as a result also has result data is converted to extended formatting and saves as the function of outside result data files; Said outside result data files form can be EXCEL or Access form; The extended formatting data file that produces can and be checked by other routine calls, can also be called by native system once more as the foreign format data.
Ventilation forecasting and early-warning system for mine is that a cover aims at mine safety production and the ventilation professional software that designs; Can carry out forecast budget to the various ventilation systems adjustment and the modification scheme in mine the present and the future each period; In time early warning is carried out in deficiency in draught, the wind speed place of transfiniting, can be assisted and carry out the mine ventilation system adjustment and improve with scheme.
