Description

Design, the method for making of horizontal positioned garden shape tank body scale

Affiliated technical field: metering and computer utility.

By searching on Internet, the domestic same industry and relevant industries are gone and found out what's going on, and relevant channel information feedback, this technology still belonged to blank in the past.

The purpose of this invention: solve metering and financial accounting problem that long-term puzzlement usage level is placed garden shape tank body unit; Further be energy-saving and cost-reducing, reduce the production cost, improve the competitiveness of product in market.

In recent years, develop rapidly along with aluminium is manufacturing, the aluminum tank body industries such as wine brewing, petrochemical industry and transportation that come into operation in a large number because advantages such as that it has is in light weight, good leak tightness, price are low, convenient transportations, are subjected to manufacturing firm and use the popular welcome of producer.But because its insufficient strength, mean level is placed, and tank body is not of uniform size, and specification is lack of standardization, makes the measurement problem of horizontal positioned garden shape tank body perplex the metering and the financial accounting personnel of enterprise always.Along with progressively perfecting of large and medium-sized enterprise's secondary system of verification, metering between each subunits, accounting problem become the pith of work again and put on work schedule, although some enterprise drops into hundreds of thousands even millions of metering system that improves oneself, often go into meaning in the actual operation process not to the utmost.Although volume pump has various advantages, maximum shortcoming is that metering is inaccurate and not directly perceived, and amount of fluid can't be calculated in the service pipe; Be subject to voltage, thermal source and strong electromagnetic; If there is foreign matter to twine the pump turbine, gross error phenomenon such as registration is motionless the liquid proper flow then can appear and; Moreover some occasion incompatibility extracts back and forth with volume pump and measures, as bulk storage number in the tank body etc.By long-term observation, concentrate on studies, we have succeeded in developing " design, the method for making of horizontal positioned garden shape tank body scale ", have all made scale at each tank body, and after coming into operation, effect is very good; Because its less investment, effect is simple and clear, and is practical, and the novelty height is subjected to real work personnel's popular welcome.It below is the concrete method for making of scale.

At first, two kinds of scales have been designed: a kind ofly be called special-purpose scale, a kind ofly be called general scale according to the actual operating position of producer.As the term suggests the scale that special-purpose scale pointer is made certain tank body, it only is used in this tank body; Its scale method is unit with the volume, and according to the specific requirement of producer, per 0.1 cubic metre or 0.01 cubic metre even 0.0001 cubic metre is the one division lattice, the corresponding corresponding tank body height of per minute degree lattice; Because shape tank body centre in horizontal positioned garden is wide, two is narrow up and down, the scale of this scale is uneven.General scale refers to scale that each tank body all is suitable for, and its scale method is a unit with the tank body height, and according to the specific requirement of producer, per 0.1 meter or 0.01 meter even 0.0001 meter is the one division lattice, the corresponding corresponding tank body volume of per minute degree lattice; The scale of this scale is uniformly, when certain this scale is used in each different tank body, must be used with the data form of a special use, and this form outlines the tank body volume of per minute Du Ge unit correspondence in detail according to producer's requirement.

The key that scale is made is to calculate, and whether accurate precision, the correctness with calculating of scale be closely related.Past if make a scale, will be calculated the data of each calibration lattice because computational tool and computing method are backward relatively, can think the quite heavy complexity of calculated amount; Even made a scale change expense one month even the longer time, precision, correctness also can't guarantee.By looking for rule and repeatedly practice, revise repeatedly, I with computer compilation " horizontal positioned garden shape tank body height/volume corresponding relation computing system " software, solved this difficult problem well, one wheat harvesting period even the workload of longer time are compressed to a few minutes just can be finished, the work efficiency that improves can't be calculated, and precision, correctness have had qualitative leap.

This computing system software has advantages such as usable range is wide, accuracy is high, easy and simple to handle, it is applicable to that the cross section is the various tank bodies in garden, ellipse garden, different requirements at the user, multiple algorithms such as height corresponding volume, volume respective heights have been designed, as long as the user is by parameters such as the garden shape radius (or major radius, short radius of ellipse garden shape) of interface prompt input tank body, length of tank, computational accuracies, just can calculate and meet the various data that producer requires, the calculation result data precision can reach 14 decimals behind the radix point, can satisfy the actual demand of producer fully.Scale accuracy height, the expense produced thus are low, practical, produce a desired effect fully.Its workflow diagram is seen Figure of description (Fig. 1: " horizontal positioned garden shape tank body height/volume corresponding relation computing system " software workflow figure).

After moving this computing system software, at first requiring the user to import accesses to your password, input is incorrect if access to your password, can not enter this computing system, after correct input accesses to your password, show this software for information about, comprise that software opens with the people, the unit of licensing, the workbench of this software, version number, warning and relevant information etc., then enter [scale computing system 1.0] main interface, in this interface, comprise [tank body shape], [help], menu items such as [withdrawing from], with click [tank body shape] menu item, this menu item right side occurs one simultaneously and comprises [garden shape], the pull-down menu of [ellipse garden shape] two selections, mouse is shifted to wherein each, occur one again simultaneously on this menu item right side and comprise [general scale], the pull-down menu of [special-purpose scale] two selections, again mouse is shifted to wherein each, will be occurred one simultaneously on this menu item right side and comprise [demonstration], the pull-down menu of [printing] two selections; Double-click wherein each, the framework of input tank body parameter will occur, correctly import a parameter by [determining] key after, enter the input framework of another parameter, till having imported all parameters of tank body; If in the input process, input data error, removable cursor key are made amendment or are re-entered by [cancellation] key, and the parameter of input comprises garden shape radius (or ellipse garden major radius, short radius), length of tank etc.; After having imported the tank body parameter, enter next framework, require the input computational accuracy, computational accuracy is according to the actual conditions of using producer, input value is more greatly the lower data of precision as far as possible, generally selects 0.01 or 0.001 the best, and too big (0.1 or bigger) can not meet the demands, too little (0.0001 or littler) will influence computing velocity and cause the wasting of resources; After having imported all parameters, will show on the computer screen or printer will print result of calculation, promptly various corresponding relation data.
