As shown in FIG. 1, the system S includes an investor terminal 1, a fund management server 2, and a crowd funding platform 3.

It is preferable that crowd funding includes a plurality of investor terminals 1 in that the basic concept is to invest the capital of a large number of investors and to invest in a company with a growth potential. The investor terminal 1 may be a computer of each investor, a mobile device, and the like.

Next, the fund management server 2 is a server 2 provided in the fund managing company, and may be provided to connect other investors other than the investors participating in crowd funding.

The fund management server 2 may include a database (storage section 23), communication means (communication section 21), control program (control section 25), and the like. .

Next, the crowdfunding platform 3 is constructed to be linked to the investor terminal 1 and the fund management server 2, and is provided for grouping a plurality of investors and creating a large amount of money by collecting the funds.

The crowdfunding platform 3 is preferably provided by a client installed in the investor terminal 1. Such a client may be represented by an application in the case of a mobile device and by an execution program in the case of a computer.

Therefore, the crowdfunding platform 3 is an environment (infrastructure) constructed to bundle a plurality of investors and exchange data with the fund management server 2. Such a crowdfunding platform 3 may be implemented by a software module (including a central processing unit) installed in the investor terminal 1 and the fund management server 2, depending on the source programmed in the client.

FIG. 2 is a block diagram illustrating the functions of the crowdfunding platform 3 in order to explain the characteristics of the system S. FIG. Referring to FIG. 2, each sub function of the crowned funding platform 3, which is a characteristic of the system S, will be described in detail.

Therefore, when the fund management company purchases the stock for the growth company through the investment sharing unit 31 of the system S, it sets a part of the purchased shares as a share and shares it with the crowdfunding platform 3 And provides investors with the purchase of this share.

Next, the redemption request unit 32 receives the redemption request from the investor terminal 1, and performs two main functions. One is to transmit the secondary investment information received from the fund management server 2 to the investor terminal 1 so that the investor can check the secondary investment information, The buyer can receive the request for redemption of the stock exchange and confirm the redemption intention for the share.

Next, the redemption processing unit 33 is configured to purchase shares in the secondary investment according to the request for redemption, and proceeds to redemption for the shares, thereby returning the profits to the investors through the redemption processing unit 33 .

The system (S) having the above-described configuration and features is designed to provide a venture company with investment for venture businesses, provide capital for promoting business items, and provide investors with efficient profit generation , And the fund manager has the effect of providing funds securing means and means of securing investment funds.

The next sharing step S2 is a step in which the crowd funding platform 3 shares a portion of the number of shares (share) with the investor terminal 1 according to the first investment information received from the crowd funding platform 3, The step S1 and the sharing step S2 are performed by the investment sharing unit 31. [

In particular, for the sake of investment stability, it is desirable that the above share is restricted to 25% of the number of first-tier investment shares. If more than 25% of shares are shared by a large number of individual investors, the management rights of the venture firms may be threatened. Also, since the proportion of the number of shares to be invested in the secondary investment is too large, the burden on the fund management companies may be increased Because.

The next secondary investment information receiving step S3 is a step of receiving the secondary investment information from the fund management server 2 by the crowdfunding platform 3 and the secondary investment information is also the same as the primary investment information Information about the venture company, number of investment shares, investment price, etc., and may further include information about the share.

Next, the second investment information transmission step S4 is a step in which the crowdfunding platform 3 transmits the secondary investment information to the investor terminal 1, and through this step S4, to provide.

The next refund request receiving step S5 is a step in which the crowdfunding platform 3 receives a refund request for the share, and the method receives the refund request of the investor in step S5 and proceeds the refund process .

The secondary investment information receiving step (S3), the secondary investment information transmitting step (S4), and the redemption request receiving step (S5) are performed by the redemption requester (32).

The next buying step S6 is a step in which the crowfing platform 3 buys a share if a redemption request is transmitted from the investor terminal 1. This step S6 is performed by the redemption processing unit 33 described above It proceeds.

In particular, in the purchase step (S6), the purchase price of the share is preferably 30% higher than the first investment price or 30% lower than the second investment price. It is a matter of course that the purchase price of the shareholder should be made at a price 30% higher than the first investment price or 30% lower than the second investment price for the satisfaction of the investor.

Of course, it is also possible to provide only the filtering unit 54. However, since the level adjusting unit 51 sets the voltage level of the stable signal, the control signal can be maintained at a constant level, The signal is amplified to detect the noise more sensitively and the driving of the filtering unit 54 can be selectively operated according to the noise detection through the filter driving unit 53 so that the life of the filtering unit 54, The life of the capacitors C114 to C117 provided in the capacitor 54 is extended.

In addition, the fact that the filtering unit 54 is not driven at all times and is selectively driven according to whether or not noise is detected can provide a remarkable effect in reducing power consumption.
