Technical field

The present invention relates to teaching demonstration method and technology field, in particular to a kind of construction engineering cost teaching demonstration method.

Background technique

Construction engineering cost generally refers to carry out the expense that a certain engineering construction is spent, i.e., from establishing final acceptance of construction Full payment used in handing over.It is taken by building installation engineering, equipment Work tool purchase commodity, and engineering construction is other to take and reserve fund And tax composition.

The course for having opened up construction engineering cost profession in the course of university now, can turn out to engineering in this way The relevant professional of cost technical field.But in the teaching of project cost, by the way that a specific engineering pair can be passed through Student explains, and the engineering mostly demonstrated in teaching is all that teacher is imagined, thus can be with reality Engineering there are some differences.It is also resulted in when demonstration in this way, cost cannot be carried out according to true situation meeting engineering.

Summary of the invention

The purpose of the present invention is overcoming above-mentioned problems of the prior art, a kind of construction engineering cost teaching is provided and is drilled Show method, by the way that actual engineering is showed student with virtual technological means, cost is being carried out according to the concrete engineering, is being made It obtains during teaching, specific example is more close to reality.

For this purpose, the present invention provides a kind of construction engineering cost teaching demonstration method, include the following steps:

S1: obtaining the project completed in project publicity on the net, obtains each stage progress of the project completed And cost information corresponding to the progress in each stage, and the project to be demonstrated for receiving user's selection will be demonstrated with the project Stage information；

S2: according to the project to be demonstrated and the information in the project stage to be demonstrated of user's selection, which is existed The progress in the stage constructs the 3-D view of the project at this stage by the means of three-dimensional simulation, and 3-D view is shown to User；

S3: user carries out the assessment of the stage project cost according to the 3-D view of the project at this stage, and will assessment Numerical information carry out typing；

S4: by the numerical value of the numerical information of the project cost of user's typing and the project actual project cost at this stage Information compares, and the difference obtained between the two feeds back to user.

Further, in step sl, include the following steps:

S1-1: the project of publicity is obtained on the net in project publicity；

S1-2: by being split according to each stage of publicity of project obtained in step S1-1, each stage is obtained Publicity content；

S1-3: the cost information in the publicity content in each stage is extracted respectively；

S1-4: the stage to be demonstrated in the project to be demonstrated and the project of user's selection is received.

Further, in step S1-2, according to being split for each stage of publicity, include the following steps:

S1-2-1: the publicity full text of publicity project is extracted；

S1-2-2: being retrieved in the full text of publicity according to the keyword of setting, and marks the keyword retrieved Position；

S1-2-3: separator is set in the top of the position for the keyword that label retrieves；

S1-2-4: interception segmentation is carried out in the position of separator, each stage of the publicity after being divided.

Further, in step s 2, include the following steps:

S2-1: the stage to be demonstrated in the project to be demonstrated and the project of user's selection is received, and according to the project The stage extract the progress msg of the project at this stage；

S2-2: it is searched in three-dimensional modeling data storehouse according to the progress msg in the stage obtained in step S2-1 and this The corresponding 3-D view of mesh information；

S2-3: the 3-D view found is shown to user by way of threedimensional model；

Corresponding to each progress msg and each progress msg of the three-dimensional modeling data storehouse for stored items 3-D view.

Further, in step s 4, include the following steps:

S4-1: by the number of the numerical information of the project cost of user's typing and the project actual project cost at this stage Value information carries out the conversion of format, is allowed to be converted into the numerical value of format；

S4-2: by the numerical information of the project cost of user's typing after conversion and the project actual engineering at this stage The numerical information of cost carries out division arithmetic and obtains the ratio of the two；

S4-3: by properly converting for the ratio both obtained in step S4-2, and by after conversion as the result is shown To user.

A kind of construction engineering cost teaching demonstration method provided by the invention, has the following beneficial effects:

1, it by the way that actual engineering is showed student with virtual technological means, is made according to the concrete engineering Valence, so that specific example is more close to reality during teaching.
