Description

Heavy equipment trading system

The present invention relates to a heavy equipment trading system, and more particularly, to a heavy equipment trading system for purchasing or selling heavy equipment online so that used heavy equipment can be traded not only in Korea but also abroad.

With the development of information and communication (Information & Technology, IT) technology, many tasks and sales activities that were performed offline in the past are being performed online.

Among online sales, sales of online shopping malls and open markets in which goods or services are transacted using the Internet network or other data communication networks are the most routinely performed.

As online transactions become more active, online transactions for second-hand products are also becoming more and more active, beyond simply transacting new products through a communication network.

A seller who wants to sell used products for the transaction of used products uses a terminal to access an appropriate server or platform through a communication network, registers a used product, contacts a buyer who meets the conditions to negotiate a price, or Connect to a company that specializes in purchasing products or a server operated by this company and request the purchase of used products.

In a conventional used product sales system using a communication network, a seller transmits an image of a used product along with information on the used product owned by the seller so that the buyer can check the status of the used product.

However, since the seller cannot check the condition of the used product such as the appearance or operation of the used product, the reliability of the used product is lowered.

Since there is no platform that can objectively and neutrally check the status of used products, online trading of used products requires a lot of time and effort.

On the other hand, Republic of Korea Patent No. 10-2234602 B1 (2021.03.26.) discloses a used vehicle direct transaction service provision system, but limits only direct transactions, not used vehicle consignment transactions. There was a problem that a transaction had to be made, but there was no way to guarantee reliability to the buyer.

The present invention is intended to solve the above problems, and in the case of used heavy equipment transactions, due to the nature of many consignment transactions by purchasing overseas, it guarantees reliability to the buyer during consignment transactions, and provides a heavy equipment transaction system that is beneficial to sellers of used heavy equipment. is intended to provide

Hereinafter, with reference to FIGS. 1 to 6, the heavy equipment trading system 1 according to an embodiment of the present invention will be described in detail.

First of all, heavy equipment means heavy machinery used in the construction field, and is classified into civil engineering equipment, packaging equipment, transport equipment, etc. depending on the purpose.

Civil equipment includes excavators, bulldozers, loaders, scrapers, etc., paving equipment includes graders and rollers, and transport equipment includes forklifts, dump trucks, truck mixers, dredges, crushers, and the like.

The heavy equipment transaction system 1, as shown in FIG. 1, is a system for online trading of used heavy equipment, and a plurality of sellers use the seller's terminal P1 as the central server 10 of the heavy equipment transaction system 1 . By communicating with the communication unit 11 of store information about each

A plurality of buyers communicate with the communication unit 11 of the central server 10 of the heavy equipment transaction system 1 with the buyer's terminal P2 to view information about the heavy equipment they want to purchase, or ask the seller about the heavy equipment they want to purchase. can do.

Furthermore, the heavy equipment trading system (1, hereinafter referred to as the system) opens a chat room between a specific buyer who wants to purchase a specific heavy equipment and a specific seller who sells a specific heavy equipment so that a specific seller and a specific buyer can answer questions in real time. do.

A plurality of consignment companies can transmit consignment company information, which is information on the location and consignment cost of the consignment company, by communicating with the communication unit 11 to the terminal P3 of each consignment company, and the memory unit 13 receives the Store the consignment company information.

The seller's terminal (P1), the buyer's terminal (P2), and the consignment company's terminal (P3) may mean a mobile communication terminal, a tablet PC, a computer, etc., and the seller's terminal (P1), the The buyer's terminal (P2), the terminal (P3) of each of the consignment company is installed with a dedicated application to implement the heavy equipment transaction system (1).

The central server 10 may mean a server computer to which the seller's terminal (P1), the buyer's terminal (P2), and each of the consignment companies' terminals (P3) connect through a dedicated application, and the communication method is several known It may be one of the methods of using various communication networks.

The communication unit 11 receives the seller information, which is information about each seller's personal information, location information, product information, and price information, from the plurality of seller terminals P1, and the memory unit 13 receives the seller information Save.

The personal information may mean a name, phone number, e-mail address, etc., location information means a residence area of the seller, price information means a desired selling price of heavy equipment that the seller wants to sell, and product information means information on the used heavy equipment that the seller intends to sell, at this time, the seller encloses a recommendation letter from a well-known industry official according to the type of heavy equipment to be sold, or the quality inspection result of the heavy equipment to be sold.

This is, of course, to ensure the reliability of the heavy equipment to the buyer who wants to purchase the heavy equipment.

The communication unit 11 also receives, from the plurality of purchaser terminals P2, individual information of each purchaser, location information, desired product information, desired price information, and purchaser information that is information about past purchase history, and the memory The unit 13 stores the seller information.

The personal information may mean a name, phone number, e-mail address, etc., location information means the residential area of the buyer, and the desired product information means information on the type of heavy equipment the buyer wants to purchase, , the desired price information means the purchase price of the heavy equipment that the buyer wants to purchase, and the information on the past purchase history indicates that the buyer has purchased the heavy equipment using the heavy equipment trading system (1) in the past and has purchased the heavy equipment. It means the purchase price of heavy equipment at the time.

The control unit 12 constituting the central server 10 checks the purchase histories of a plurality of purchasers, respectively, and calculates a purchase cost according to the purchase histories.

The method of calculating the purchase cost may be calculated as a total sum of purchase costs according to a past purchase history.

The control unit 12 calculates the purchase cost of each purchaser and groups a plurality of purchasers according to the purchase cost.

The control unit 12 sets, as a first group, personal information of each purchaser who has consumed a purchase cost that is equal to or greater than the first purchase cost, which is a predetermined purchase cost, and is less than the second purchase cost, which is an amount greater than the first purchase cost. and sets the personal information of each buyer who has consumed a purchase cost equal to or greater than the second purchase cost and less than the third purchase cost, which is an amount greater than the second purchase cost, into a second group, and purchases greater than or equal to the third purchase cost The personal information of each of the buyers who spent the money is set as a third group. (Step S100)

To explain this in more detail, for example, buyers whose past heavy equipment purchase cost is less than 300 million won are set as the first group, and buyers whose past heavy equipment purchase cost is 300 million won or more and less than 500 million won are set as the second group, Buyers whose purchase cost of heavy equipment in the past is 500 million won or more is set as the third group.

However, since the purchase cost is relatively expensive due to the characteristics of used heavy equipment, an example is given in units of billions, but it is not limited thereto, and the range of purchase cost determined by the system administrator can be changed.

The reason why the control unit 12 classifies the plurality of buyers into the first group to the third group according to the purchase cost is that each of the buyers is classified according to the purchasing power of the plurality of buyers, so that a specific seller is given to a buyer having a relatively high purchasing power. This is to provide a notice 30 with a difference in time when a new heavy equipment for sale 20 is uploaded by .

That is, a buyer with a relatively high purchasing power, when an item is uploaded by a specific seller, preferentially checks the item over a buyer with a relatively low purchasing power, and a buyer with a relatively high purchasing power induces a prompt purchase of the item.

To implement this, the control unit 12, for example, when a new heavy equipment item 20 is uploaded from the terminal 70 of a specific seller, based on the time when the item is uploaded, the communication unit 11 48 After the time, a first notification indicating that the item is uploaded is controlled to be sent to each terminal 60 of the first group of buyers. (Step S110)

That is, as can be seen in FIG. 3 , the time when the new heavy equipment for sale 20 is uploaded from the terminal 70 of a specific seller is 00:00 on August 01, 2021, and the time when the first notification is sent is 2021 The year is August 03, 00:00.

The control unit 12 sends a second notification to the communication unit 11 notifying that the item is uploaded after 24 hours from the communication unit 11 based on the time when the item is uploaded. Control to send to the terminal. (Step S110)

That is, as can be seen in FIG. 3 , the time when the new heavy equipment for sale 20 is uploaded from the terminal 70 of a specific seller is 00:00 on August 01, 2021, and the time when the second notification is sent is 2021 The year is August 02 at 00:00.

The control unit 12 sends a third notification informing that the sale is uploaded at the time the item is uploaded by the communication unit 11 to each terminal of the third group of buyers based on the time when the item is uploaded. control (Step S110)

That is, as can be seen in FIG. 3 , the time when the new heavy equipment for sale 20 is uploaded from the terminal 70 of a specific seller is 00:00 on August 01, 2021, and the time when the third notification is sent is also 2021 It is 00:00 on August 01 of the year.

However, the first notification to the third notification are, when the sale of heavy equipment different from the sale 20 is uploaded by any seller, the first notice to the first notice according to the sale of heavy equipment different from the sale 20 3 notifications are sent at a time interval, and the first to third notifications are independently sent to the terminals of the first to third groups of buyers for each sale.

On the other hand, as shown in (a) of FIG. 4, when the control unit 12 receives a purchase request for the property 20 from a terminal of a specific buyer who has received the first notification to the third notification, (Step S120) The communication unit 11 controls to provide an interface screen for selecting a direct transaction or a consignment transaction for the sale 20 to the terminal 70 of the specific seller. (Step S130)

The direct transaction means that the specific seller and the specific buyer directly meet, and the specific buyer directly confirms and transacts the property 20 .

Accordingly, when the specific seller selects a direct transaction, the control unit 12 controls the communication unit 11 to transmit the personal information of the specific buyer to the specific seller, and the communication unit 11 to the specific seller control to transmit personal information of (Step S150)

The consignment transaction means that the seller delivers the property 20 to the specific buyer through a consignment company because the physical distance between the specific seller and the specific buyer is relatively long, and the transaction is made.

This is because, due to the characteristics of used heavy equipment, there are many cases where the seller or buyer is a foreigner, not a Korean, so in many cases the sale of heavy equipment is delivered from the seller to the buyer through a consignment company.

Accordingly, the control unit 12, as shown in FIG. 4 (b), when receiving a consignment transaction request from the specific seller terminal 70, pre-stored location information of a specific seller among the plurality of consignment companies Based on this, the first consignment company, which is a specific consignment company located in a relatively close location, is recommended. (Step S160)

When the control unit 11 receives a request for a consignment transaction between the first consignment company and the item 20 recommended from the terminal 70 of the specific seller (step S170), the sale price of the item 20 A first commission rate, which is a relatively smaller commission rate than the preset sales commission rate applied to , is applied. (Step S180)

Here, the commission rate refers to a percentage (%) of the sale price of the property 20 in order to pay the system administrator a fee, which is the cost that the specific seller uses the system 1 to sell the property 20. And, for example, if the sale price of the property 20 is 100 million won and the set commission rate is 10%, the commission to be paid by the specific seller to the system developer is 10 million won.

That is, if the preset sales commission rate is 10%, the first commission rate may mean 8%.

The reason why the control unit 12 applies the first commission rate is that the specific seller uses the first consignment company recommended by the system 1 to transport the property 20 to the area where the specific buyer is located. Because the specific seller must also pay the cost for the consignment of the property 20 to the first consignment company, in order to reduce the burden of cost, and at the same time, the control unit 12 applies the first fee rate This is because, because of its advantages, it is possible to induce a new seller to use the system 1 rather than the specific seller.

That is, from the standpoint of the system 1, it is because it is possible to secure a new customer (a new seller).

However, the preset fee rate and the first fee rate can be changed by the system administrator.

On the other hand, when the control unit 12 receives information about rejection of the consignment transaction with the first consignment company recommended from the terminal 70 of the specific seller, as shown in FIG. 5 , the An interface screen for requesting input of the consignment company information for a second consignment company that the specific seller wishes to consign to a terminal of a specific seller is provided.

This is to broaden the selection of the consignment company of the specific seller, and also because there may be a consignment company in which the specific seller has maintained a transaction.

The specific seller transmits the consignment company information about the second consignment company to the communication unit 11 using the terminal 70 of the specific seller. (Step S190)

When receiving the consignment company information for the second consignment company from the terminal of a specific seller, the control unit 12 determines whether the second consignment company is included in the pre-stored consignment company. (Step S200)

When the second consignment company is included in the pre-stored consignment company, the control unit 12 applies a commission rate applied to the sale price of the item 20 as the first commission rate. (Step S210)

This is because, from the standpoint of the system (1), a plurality of sellers, a plurality of buyers, and a plurality of consignment companies may all be customers, and the second consignment company that the specific seller has maintained a transaction with is also from the standpoint of the system (1). Because you are an existing customer.

On the other hand, when the second consignment company is not included in the pre-stored consignment company, the control unit 12 applies a second commission rate, which is a commission rate that is relatively smaller than the first commission rate, a commission rate applied to the sale price of the item. . (Step S220)

This is because the specific seller introduces the system 1 to a second consignment company that is a new customer from the standpoint of the system 1, and new customers are introduced from the standpoint of the system 1.

For example, if the first fee rate is 8%, the control unit 12 may apply the second fee rate to 6%, and the numerical values for the first fee rate and the second fee rate are for convenience of explanation. This is only an example, and can be changed by the system administrator.

On the other hand, when the specific seller is included in any one of the first group to the third group (step S230), the control unit 12 compares the commission rate applied to the sale price of the item to the second commission rate. The third fee rate, which is a small fee rate, is applied. (Step S250)

To explain this in more detail, due to the nature of the used transaction, the seller can not only sell, but also play the role of a buyer. By combining the sales price and capital, a fork crane with relatively better performance than the previously used fork crane can be purchased through the system 1 .

That is, the seller sells heavy equipment at the present time, but may have a history of purchasing heavy equipment in the past, and may purchase heavy equipment needed in the future.

Accordingly, if a specific seller selling the item 20 has a history of purchasing necessary heavy equipment through the system 1 in the past, the control unit 12 sets the commission rate applied to the sale price of the item to the second The third commission rate, which is a relatively smaller commission rate than the commission rate, is applied.

In this case, from the standpoint of the system 1, if a specific seller selling the property 20 has a history of purchasing necessary heavy equipment through the system 1 in the past, purchase the necessary heavy equipment through the system 1 in the past. Because it is a more important customer than a seller without a history, it is to provide a relatively large benefit.

The control unit 12, for example, if the second fee rate is 6%, the third fee rate may be applied as 4%, and the figures for the second fee rate and the third fee rate are for convenience of explanation. This is only an example, and can be changed by the system administrator.

The controller 12 applies the first commission rate or the second commission rate, not the third commission rate, when the specific seller is not included in the first group or the third group. (Step S240)

On the other hand, the control unit 12 to prevent the so-called reseller from purchasing heavy equipment through the system 1 and reselling through the system 1, the so-called reseller recognizes the license plate of each item for sale. or by assigning a unique identification code to each of the items for sale of heavy equipment, a well-known identification method or recognition method may be used.

When the re-seller purchases a specific property through the system 1 and a predetermined time elapses, and uploads the specific property for sale to the system 1, the A fourth commission rate that is relatively larger than the preset sales commission rate applied to the sale price of the item is applied.

The control unit 12, for example, if the preset commission rate is 10%, the fourth commission rate may be applied as 30%, and the preset commission rate and the numerical values for the fourth commission rate are an example for convenience of explanation. However, it can be changed by the system administrator.

This not only prevents the reseller from taking unfair advantage through the system 1, but also allows a specific buyer to buy and sell a plurality of items through the system 1, so that a specific buyer buys a plurality of items through the system 1 Of course, this is to prevent taking unfair profits by selling.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and it is understood that various changes or modifications can be made within the spirit and scope of the present invention. It is intended that such changes or modifications will be apparent to those skilled in the art, and therefore fall within the scope of the appended claims.
