An embodiment of a competitive bidding system of the present invention will be described with reference to the drawings. The connection device and the competitive bidding device of the present invention are included in the competitive bidding system. Also, the competitive bidding method of the present invention will be described. In the following embodiments, the same components are denoted by the same reference numerals, and redundant description will be omitted.

(1) First embodiment

A first embodiment of the competitive bidding system of the present invention will be described with reference to the drawings. This embodiment is an auction system in which a plurality of bidders present a bid price for a presented product, and a person who presents the highest bid price makes a bid for the product and purchases it. First, the configuration of the auction system according to the present embodiment will be described. FIG. 1 is a system configuration diagram of an auction system according to the present embodiment, and FIG. 2 is a diagram illustrating a processing flow and a data flow in the option system according to the present embodiment. In FIG. 2, continuous auction processing is shown in a time-sharing manner in order to facilitate understanding. Figure 2 shows that the distance between the sub auction device 14 and the connection device 16 is relatively short (for example, about several kilometers), and the distance between the connection device 16 and the main auction device 12 is extremely long. (For example, about tens of thousands of km).

The auction system 10 according to the present embodiment includes a main auction device 1

2 (first competitive bidding device) and sub-auction device 1 4 (second competitive bidding device) And a connection device 16. Hereinafter, each component will be described in detail.

The main auction device 12 presents the products to be auctioned to the auction participants, and accepts bids from a plurality of participants to perform auction (competitive bidding). More specifically, the main auction apparatus 12 is connected to an input terminal 100 provided for each of a plurality of participants by a dedicated line, and each of the plurality of participants uses the input terminal 100 Thus, a bid can be made on the main oak device 12.

As shown in FIG. 3, the input terminal 100 includes a keyboard 102, a display 104, and a post switch 106. Before the auction starts, the main auction device 12 distributes information (including video) of the product to be auctioned to the input terminal 100 using a satellite line, and the information of the product is It is displayed on the display 104 of the input terminal 100. In other words, the participant can operate the keyboard 1 2 before the auction starts to display the product to be auctioned on the display 104 and preview the product. After the auction starts, participants can bid on the main auction device 12 by pressing the bidding button 106a provided on the POS switch 106. That is, after the auction starts, the bid price of the bidder who is currently winning in the main auction device 12 (hereinafter referred to as the bid price) is input from the main auction device 12 through the dedicated line. Transmitted to 100 and displayed on display 104. On the other hand, by pressing the bid button 106a, the participant can bid at a bid price obtained by adding a bid unit price to the bid price displayed on the display 104. For example, if the bidding price is 100,000 yen and the bidding unit price is 300,000 yen, every time any one of the participants presses the bidding button 106a, the bidding on the main auction device 12 is performed. The price is auctioned by 30.0 yen Will be. Here, since the main auction device 12 detects a bid from each input terminal 100 at an extremely short period (for example, 100 ms), immediately after the start of the auction, the winning price rises rapidly. Go. In addition, the main auction device 12 determines the final bid price when the bid has not been received from any participant for a certain period of time or when the bid price has risen to the seller's desired price. The bidder who bid is determined as the successful bidder. With such a mechanism, in the case of a used car auction, it may take only tens of seconds from the start of the auction to the determination of the winning bidder.

Further, the main auction device 12 accepts a bid from a bidder who has won in the sub auction device 14 via the connection device 16, the details of which will be described later.

Similar to the main auction device 12, the sub auction device 14 presents the merchandise to be auctioned to the auction participants and accepts bids from a plurality of participants to conduct the auction. More specifically, the sub-function device 14 is connected to an input terminal 100 provided for each of a plurality of participants by a dedicated line, and each of the plurality of participants uses the input terminal 100. Thus, a bid can be made for the sub auction device 12.

Here, the sub-auction device 12 causes the bidder who has won the bid in the sub-option device 12 to participate in the main auction device 14 as a bidder via the connection device 16, which will be described in detail later.

The connection device 16 connects the main auction device 12 and the sub auction device 14. More specifically, the connection device 16 determines the bid price for the main auction device 12 based on the bid price of the bidder who is winning in the sub auction device 14, and uses the bid price to determine the main auction device. Bid on 1 2 Here, in particular, the connection device 16 wins the sub auction device 14 By adding a fixed amount determined based on the delay time of signal transmission from the sub auction device 14 to the main auction device 12 to the bid price of the existing bidder, the bid for the main auction device 12 is added. Determine the price. More specifically, the period at which the main auction device 12 detects bids from a plurality of input terminals 100 (pressing the bidding button 106a of the POS switch 106) is set to 100 ms, If the delay time of the round-trip signal transmission from the auction device 14 to the main auction device 12 is 300 ms, and the bidding unit price of the main auction device 12 is 300 yen, go to the sub auction device 14 The maximum bid price of the main auction device 1 2 is up to 30% after the bidder of the sub auction device 14 bids on the sub auction device 14 and bids on the main auction device 12. 0 yen X 3 times, that is, there is a possibility of rising 900 yen, and when bidding is performed frequently, the participants of the sub auction device 14 It is difficult to fight in person and equal. Here, the connection device 16 is the maximum increase in the auction price of the main auction device 12 within the delay time of the signal transmission with respect to the bid price of the bidder winning in the sub-auction device 14. The bid price for the main auction device 12 is determined by adding 0 0 yen, and a bid is made to the main auction device 12 at the bid price.

In addition, the connecting device 16 determines the bid price of the bidder winning in the main auction device 12 based on the bid price of the bidder winning in the main auction device 12, The auction price to be provided to the auction is determined, and the offered price is notified to the sub auction apparatus 14. Here, in particular, the connection device 16 sets the delay time of the signal transmission from the main auction device 12 to the sub auction device 14 to the bid price of the bidder winning in the main auction device 12. The above-mentioned offer price is determined by adding a certain amount determined based on this. More specifically, The cycle at which the Yong device 12 detects bids from a plurality of input terminals 100 is 100 ms, and the delay time of the round trip signal transmission from the main auction device 14 to the sub auction device 14 is 300 ms, when the bidding unit price in the main auction apparatus 1 2 is 300000 yen, the winning price in the main auction apparatus 1 2 is the input terminal 100 of the participant of the sub auction apparatus 1 4 4 At the time of presentation, there is a possibility that the winning price in the main auction apparatus 12 is up to 300000 yen x 3 times, that is, 90000 yen. Therefore, in this case, even at the same time, the participant of the sub-auction apparatus 14 receives the bid price of 900 yen less than the participant of the main-action apparatus 12. That is, when bidding is frequently performed, it is difficult for the participants of the sub auction apparatus 14 to compete with the participants of the main auction apparatus 12 on an equal basis. Therefore, the connecting device 16 is the above-mentioned 90 which is the maximum increase in the winning price of the main auction device 12 within the signal transmission delay time with respect to the bid price of the bidder winning in the main auction device 12. The offer price to be presented to the participants of the sub auction apparatus 14 is determined by adding 0 yen, and the offer price is notified to the sub auction apparatus 14.

The main auction device 12 that receives the bid from the connection device 16 includes a bidder who directly bids on the main auction device 12 from the input terminal 100 and a connection device 16 that functions as a bidder. An auction is conducted between the two and the bidder including the connection device 16 is determined to be the successful bidder by winning the bid in the main auction device 12.

Here, when the connection device 16 becomes a successful bidder in the main auction device 12, the main auction device 12 notifies the sub auction device 14 via the connection device 16 to that effect. Upon receiving this notification, the sub-auction device 14 determines the bidder who has won the bid in the sub-auction device 14 as the successful bidder. Next, the operation and effect of the auction system according to the present embodiment will be described. The auction system 10 according to the present embodiment does not make all the bidders for the sub auction device 14 bid to the main auction device 12 as it is, but only the bidder who has won the sub auction device 14 in the main auction device. Auction equipment 1 and 2 are bidding. Therefore, it is possible to accept bids from many participants in the competitive bidding performed by the main auction apparatus 12 without significantly increasing the processing load of the main auction apparatus 12. As a result, an auction system that is easy for many participants to use is realized. For example, a main auction device 12 capable of processing bids of 1000 participants and a sub-auction device 14 also capable of processing bids of 1000 participants are connected. When the auction system 10 is configured as such, the main auction device 12 which has only the ability to process the bids of 100 participants can be directly transmitted from the 999 participants and the sub auction device 14. It is possible to hold an auction in which a total of 199 9 participants, including 100,000 participants. In addition, by increasing the number of sub auction devices 14 connected to the main auction device 12 or by connecting the sub auction devices 14 hierarchically, participants in the auction held in the main auction device 12 Can theoretically be increased without limit.

Further, the auction system 10 according to the present embodiment provides a delay in signal transmission from the sub auction device 14 to the main auction device 12 with respect to the bid price of the bidder who is winning in the sub auction device 14. By adding a fixed amount determined based on time, the bidding price for the main auction device 12 is determined, and the bid price of the bidder who is winning in the main auction device 12 is compared with the main auction device 12. By adding a fixed amount determined based on the delay time of signal transmission from 12 to the sub-auction device 14, the offer price to be presented to the participants of the sub-auction device 14 is determined. Therefore, The influence of the delay time of the signal transmission on the auction can be reduced. As a result, an auction system that is easy to use for participants who participate from remote locations will be realized. Here, auctions between general consumers via the Internet are often held for several days to several weeks, and in most cases, the delay time of signal transmission does not matter. However, in so-called business-to-business auctions, such as used car dealerships with used car dealers, the successful bidder is often determined within a few seconds to several tens of seconds, and transmissions are delayed due to transmission signal delays. Delays in bills are fatal. Therefore, the auction system 10 according to the present embodiment can be very effectively applied to a so-called business “toe” business auction such as the used car auction described above.
