Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a compressor, and more particularly to a non-general-purpose compressor in which required specifications vary widely for each customer.
The present invention relates to an estimation method for replying an estimation result to a customer via a network, and an estimation support system for executing the method.

[0002]

2. Description of the Related Art Focusing on the form of manufacture and sale of a compressor, a general-purpose compressor that performs a relatively large amount of manufacture and sale according to predetermined specifications, and a compressor based on specifications required by a customer. It is roughly divided into non-general-purpose compressors that manufacture and sell small quantities. General-purpose compressors have various specifications, such as the type of gas to be used, their allowable suction temperature, pressure, assumed discharge temperature, and pressure, in order to meet the needs of many customers. It is set for each finite number of models. When purchasing such a general-purpose compressor, the customer requests the product from a catalog distributed by a manufacturer who sells and sells the product and a list of manufacturing and sales items published on the Internet homepage. In many cases, a general-purpose compressor of a type close to the specifications to be selected was selected, and the quantity of the general-purpose compressor was presented to the manufacturer and seller to make an estimate. Alternatively, the specifications requested by the customer are presented to the manufacturer / distributor at a meeting or the like, and the manufacturer / distributor brings it back and examines it repeatedly to select and estimate a general-purpose compressor that meets the specifications according to the customer's request. Was doing.

However, the specifications of the compressor required by the customer are not uniform. Especially in plants, etc.
Compressors having various specifications such as gas types, pressure conditions, and temperatures are required for each plant. It is often difficult for a customer alone to select an appropriate compressor that meets the specifications required by the customer. There are many cases where an existing general-purpose compressor cannot find an applicable one, and a new non-general-purpose compressor must be newly designed. Also, in the case of a non-general purpose compressor, it is difficult to derive the estimation result only by selling by distributing pamphlets etc. listing compressors of which specifications are predetermined in advance. In many cases, a procedure for estimating that the performance is calculated and an estimate is designed to be brought back to the customer, and the result is presented to the customer later. Some non-general-purpose compressors are provided with a common model in certain limited specifications in advance, but in any case, for specifications that cannot be determined only by the model, It was necessary to perform performance calculation and estimate design based on the

[0004]

In quoting from a customer, in practice, the customer does not present the type of general-purpose compressor he or she wants to purchase to the manufacturer, but rather the required compression. It is often the case that only the specifications of the compressor are presented, and an estimate including selection of a compressor conforming to the specifications is commissioned. Then, when it is necessary to search for a model of a suitable general-purpose compressor and further to apply a non-general-purpose compressor, time and labor for the estimation design are imposed on the manufacturer and seller. Particularly in the case of non-general-purpose compressors, as described above, it is difficult to sell by distributing pamphlets etc. listing compressors whose specifications have been specified in advance. Was taken back to a place that holds reference materials and the like that can perform estimation, and performance calculation and estimation design were performed. As a result, in most cases, it took a considerable amount of time to present the estimation result to the customer. In addition, the delay in responding to such estimation results was remarkable when estimating from a remote customer.

Further, in order to quickly and appropriately respond to an estimate from a specific customer, a record of the past delivery record of the customer and the specification of the compressor specifications required by the customer at the time of the past estimate are recorded. There are advantages to referencing. However, in the past, in most cases, the records of the past delivery results and the required specifications of the compressor were printed and prepared on paper, so that handling was difficult.
Therefore, the degree of utilization as reference materials often depends on the qualities of the designers engaged in the estimation design, and as a result, it has not been fully utilized in the estimation design.

[0006] In preparing the specification, it is necessary to perform advanced performance calculations and reflect the result in the above specification. Because of the large amount of data to be handled and the complexity of the performance calculation itself, whether or not an appropriate specification can be created also often depends on the qualities of the designer who performs the specification. As a matter of fact, there were many errors in data transfer, etc., and it was difficult to say that proper specification documents could be created evenly.

[0007] The present invention has been made under such a circumstance, and its object is to provide a customer who wants to provide a quotation using a quotation method established through a network.
It is an object of the present invention to provide a compressor estimating method capable of providing a proper estimation result evenly without delay and without depending on the quality of an estimating designer, and an estimating support system for implementing the method.

According to this method, a plurality of types of compressors held in advance on a network server, that is, a specification of a compressor input by a person who desires an estimate from a category of fixed type compressors having specified specifications. Since it is the process of selecting a compressor that matches the information on the compressor, it is possible to provide the fixed information including the model as the information of the compressor determined to be manufacturable. In other words, those who wish to receive the quote provided with the information, and when ordering the subsequent manufacture and sale of compressors,
An order can be made using the standard information such as the model, and the procedure is simplified.

Next, in the invention according to claim 4 of the present invention,
In the invention according to claim 1, a unique encryption is determined for each person who desires an estimate of the compressor, and the network server specifies the person who wants the estimate of the compressor by the compressor. The person desiring the estimate accesses the network and performs the encryption based on the encryption.

[0015] Thus, there is no possibility that the information of the person who wants to estimate the compressor and the fact that the person wants the estimate itself is known to a third party. Also, if the contract is always undertaken with the above-mentioned encryption, it becomes easier for the network server to discriminate the estimation result for each person who desires the estimate.

Next, in the invention according to claim 5 of the present invention,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings. However, the configuration shown below does not limit the present invention,
Any design change in the spirit of the following or the following is included in the technical scope of the present invention.

FIG. 1 schematically shows the structure of a compressor estimation support system according to the present invention. A network server 2 is connected to the network line 1. This network server 2 is a contractor for contracting quotes for compressors,
In other words, a company that manufactures and sells compressors holds
Managing. Further, the network line 1 can be accessed by a plurality of applicants for estimating. Here, traders C ₁ , C ₂ , and C ₃ are illustrated as the applicants for estimation.

Such a network line 1 may be a dedicated line laid so as to connect a contractor who makes a contract with another contractor who is a specific customer who wants a quote.
In addition, a line other than such a dedicated line may be used. In the former case, there is a security advantage that the fact that a series of estimation actions such as requesting an estimate or undertaking the estimate and the contents thereof are less likely to be known to a third party is low. Also, because of the dedicated line, information can be exchanged between networks at high speed. On the other hand, the non-dedicated line referred to as the latter is, for example, a network using the Internet, which can be used for a wide range of users, and in an existing network environment which is already widely used. , There is no need for the cost of new infrastructure development, etc., which is a great economic advantage. In addition, the penetration of encryption technology for information transfer and the improvement of so-called firewall system technology have recently solved security problems. Hereinafter, the network line 1 shown here will be described as being constructed with a line other than a dedicated line using the Internet or the like.

The network server 2 is connected to a plurality of network terminals 3, 4, 5 via a network line 1. Of course, the network terminals 3, 4, 5 may be of a stationary type connected to the network line 1 by wire, or a portable type of wirelessly connected to the network line 1. The network terminals 3, 4, and 5 are configured so that a person who desires an estimate directly operates and can refer to an estimation result described later on the network terminal. The person who operates the network terminals 3, 4, and 5 and who wants an estimate may be the person who wants to be finally provided with the result of the estimate, or may be entrusted to the person to undertake the work of the estimate. May be a person.

The network server 2 has a built-in program for executing various calculations related to the estimation design, and relates to a request from the network terminals 3, 4, and 5 for a request from a person who wants an estimate. The transmission of the signal is detected, the program is executed, the result is returned to the network terminals 3, 4, and 5 again, and the result is provided to a person who wants an estimate.

FIG. 2 shows the correlation between the main program, each program, and the database. When the above programs are classified by function, (1) Performance calculation (Sizin
g), (2) Preparation of specifications (Specification), (3) Preparation of piping and instrumentation drawings (P & ID), (4) Preparation of layout drawings (Layout), and (5) Price estimation. Furthermore, as functions to support estimation design, (6) past case search function (CaseSearch),
(7) There is a function (DataBase) that supports data operations between the shared database and the personal database. These various programs are controlled by the main program.

The network terminals 3, 4, and 5 provide an input screen for allowing a person who wants an estimate to input information relating to the specifications of a compressor which the user wants to estimate. (Sizing) and various calculations are performed, and an output screen for presenting the calculation results is displayed. FIG. 3, FIG. 4, and FIG. 6 are examples.

FIG. 3 shows an initial input screen for selecting a desired process from various calculations. That is,
(1) Performance calculation (Sizing), (2) Specification creation (S
pecification), (3) Piping instrumentation diagram creation (P & ID), (4)
Layout drawing (Layout), (6) Search function of past cases (CaseS
(7) An input screen on which various treatments of a function (DataBase) for supporting data operation between the shared database and the personal database can be selected. This input screen is a dialog box displayed on a display device such as a display of the network terminals 3, 4, and 5. By mouse click on the rectangular part in this dialog box,
Execute each process.

Specifically, the above (1) performance calculation (Sizin
g) will be described below as an example, and the description of other processes will be omitted. "Si" on the dialog box shown in Fig. 3
When the mouse clicks on the rectangular part with the notation "zing", an input screen as shown in FIG. 4 is newly displayed on a display device such as a display of the network terminal. This input screen is configured so that the user who wants an estimate can input information about the specifications of the compressor, such as suction pressure (Ps), discharge pressure (Pd), air volume (capacity), gas type, etc. ing. After inputting information about the specifications of the compressor on this input screen, performance calculation (Sizing) is executed by clicking on the rectangular part with the word "calculate" at the approximate center of the upper part of the input screen. Is done.

FIG. 5 is a simplified flowchart of the performance calculation (Sizing) process, including the procedure for inputting information on the specifications of the compressor. Input information related to gas, such as suction pressure (Ps), discharge pressure (Pd), air volume (capacity), gas type, etc., and also input the compressor model. The data is sent to the network server 2, where the calculation of the internal compression ratio, the calculation of the volumetric efficiency, the calculation of the power, and the like are executed on the network server 2. If it is determined that the volumetric efficiency satisfies the requirements of the person requesting the estimate, that is, whether it is possible to manufacture a compressor with the specifications of the information presented by the person requesting the estimate, In addition, the result of the performance calculation is displayed on an output screen as shown in FIG. If it is determined that manufacture is impossible, a dialog box (not shown) including a message prompting re-input is displayed, and the screen returns to the input screen shown in FIG. 4 again.

By estimating a compressor using such an estimation support system, a person who wishes to estimate a compressor can determine whether a compressor having desired specifications can be manufactured or not. In this case, more detailed specifications of the compressor can be immediately provided as a result of the estimation via the network line 1 to a person who desires an estimate of the compressor. Further, since the determination as to whether or not the compressor can be manufactured is based on a fixed determination routine held as a function by the network server 2, artificial determination is excluded, and an even and appropriate determination result can be derived.

In the above description, the input information includes the type of the compressor, but the present invention is not necessarily limited to this. The person requesting the quote is often unaware of the compressor type information. In such a case, the requester of the estimate is made to input only the gas information, and the network server 2 uses the input information and the information of the compressor stored in the network server 2 in advance to determine a suitable compressor. The model may be extracted, and information on the extracted model of the compressor may be displayed on the output screens of the network terminals 3, 4, and 5 as calculation results. In any case, if it is possible to provide standard information including the model as information on the compressor determined to be manufacturable, those who wish to receive a quotation provided with the information,
Also when ordering the manufacture and sale of the compressor thereafter, the order can be made using the standard information such as the model, which is advantageous in that the procedure is simplified.

Further, a unique encryption is determined for each person who wants an estimate of the compressor, and the network server 2 wants the estimate of the compressor to specify a person who wants an estimate of the compressor. The user may access the network line 1 and perform the encryption based on the encryption. In this way, even if a third party can see the quote information due to unauthorized access, etc., since the information of the person requesting the quote is encrypted, the person who wants the quote to the third party cannot It is impossible to identify who it is, which has security benefits. In addition, there is an advantage that it is easy to separate the estimation result for each person who desires the estimation on the network server 2.

Further, the network server 2 is a system in which a person who wishes to estimate a compressor has previously been connected to the network line 1.
And has a function of retaining a history of information on the specifications of the compressor for which a quotation entered by inputting a request is input. When a person who desires a quotation of the compressor newly accesses the network line 1, The server 2 may specify a person who wants an estimate of the compressor, and may make an estimate based on the history related to the person who wants the specified estimate. For example, when displaying the input screen,
It is possible to display the input information at the time of the immediately preceding quotation on the screen, and the subsequent input work can be facilitated. Alternatively, it is possible to determine whether the information of the compressor input by the person who wants the estimate and the input information of the past estimate are the same or very similar, and in that case, the new compressor It is sufficient to provide the past estimation result without performing the performance calculation, so that the estimation can be accelerated. Of course, the person who wants the quote may be specified by the above cipher.

[0034]

The present invention is configured as described above, and according to the present invention, a method for estimating a compressor and an estimating support system for implementing the method can be realized, and the present invention can be realized via a network. By using the quotation method, it is possible to provide a customer who wants to provide a quotation without delay and even with a quotation designer's ability to provide a proper quotation result evenly.
