Description

IOT outlet power control system through watching advertisements

The present invention relates to a system for controlling power supplied to an IoT outlet. When a user watches an advertisement on a smartphone at a branch, the user's smartphone and an outlet with a built-in short-distance communication function perform wireless communication to supply power to the IoT outlet. This relates to an IoT outlet power control system that controls power supply through watching advertisements.

Recently, as quality convenience facilities have increased in various places, users who use them are increasingly spending a long time in one place.

Although it appears that there are actually a lot of customers at the branch, there may be a loss in business due to lack of seat rotation. In particular, in areas near universities, students use coffee shops like libraries, and some students stay there all day.

When customers stay at a branch, they often plug their cell phones or laptops into the outlet to use them. However, if customers stay for a long time and use the power for free, the branch is bound to spend a considerable amount of money every month.

In this way, the profitability of branches decreases due to customers staying for long periods of time, and at the same time, due to the additional electricity costs incurred by charging customers' mobile phones and laptops, some coffee shops reduce the number of outlets installed inside or install more outlets. It is being removed so that electricity cannot be used.

In other words, by reducing the number of outlets in a coffee shop or eliminating outlets in a coffee shop altogether to prevent the use of electricity within the coffee shop, the number of customers who use electricity within the coffee shop and sit in for long periods of time is reduced, and the number of customers is reduced. By increasing the turnover rate, we are increasing the profitability of our branches.

This is to prevent damage to the branch caused by many of the customers visiting branches such as coffee shops using electricity through outlets within the branch for more than 3 to 5 hours after ordering inexpensive menu items.

In particular, it is not a large franchise due to problems such as leaving a computer, including a laptop, in the seat after taking a seat in a coffee shop, going to eat with the laptop connected to the outlet, or requesting frequent refills of drinks such as coffee. In the case of coffee shops that operate as small stores, there is a problem that their livelihood may be affected by customers who occupy seats in the store for long periods of time.

In order to solve the problems described above, “Power control device for limiting use time of electronic devices (Korean Patent No. 10-1617149)” has been proposed as prior art.

Prior art restricts the supply of power required for the operation of electronic devices, including TVs, personal computers, video devices, audio devices, and entertainment devices, preventing students, children, or teenagers from using electronic devices for long periods of time without permission. In addition to correct use of devices, it is possible to promote mental and physical health, especially for children and adolescents, by allowing them to be used only for the necessary time when necessary, and by using a smartphone as a power control device to limit the use time of electronic devices. This facilitates the use of electronic devices by allowing them to be controlled from a short or long distance.

However, in addition to simply limiting the power supply time provided to the outlet to operate electronic devices, it also benefits business owners who run branches such as coffee shops, study cafes, and saunas, and customers who use the outlet at the branch do not have to pay. There is a demand for an outlet power control system that can improve customer convenience by conveniently using electricity without electricity.

The present invention was invented to improve the above problems. After recognizing the QR code of the outlet you want to use using a smartphone app, request the use of an IoT outlet containing QR information and user information to the server.

Afterwards, an IoT outlet use approval message is sent to the smartphone, and when the IoT outlet receives an IoT outlet use approval message from the smartphone using short-distance communication, the power is switched from OFF to ON to activate power supply. It is intended to provide an IoT outlet power control system through .

In addition, the advertising cost paid by the advertiser is divided between the branch where the IoT outlet is installed and the company that operates this control system, but by paying a larger percentage of the profit to the branch, the branch earns separate profits in addition to the products sold at the branch. The purpose is to provide an IoT outlet power control system through watching advertisements that can be created.

In order to achieve the above object, the IoT outlet power control system through advertising viewing according to the present invention has a built-in short-distance communication function to perform wireless communication with a smartphone, and is in the OFF state when a use approval message is received from the smartphone.

The IoT outlet power control system through advertising viewing according to the present invention includes an IoT outlet 100, a QR code 200, a smartphone 300, an advertisement server 400, and a central management server 500.

The IoT outlet 100 has a built-in short-distance communication function and performs wireless communication with the smartphone 300. When an IoT outlet use approval message is received from the smartphone 300, the power in the OFF state is turned off using an internal switch. Switch to ON state to activate power supply. Near field communication capabilities can utilize either NFC, Bluetooth, or WiFi technologies.

The IoT outlet 100 may be attached to a general outlet in a branch and be plugged into the outlet, or it may be provided as an IoT outlet 100 without a general outlet and used by inserting a plug. Even if the plug is inserted into the IoT outlet 100, power is not supplied to the plug when the internal switch is in the OFF state. However, when an IoT outlet use approval message is received from the smartphone 300, the internal switch is switched to the ON state to activate power supply to the plug.

The QR code 200 is attached to the outside of the IoT outlet 100 and contains unique information for each outlet. In other words, each outlet has a unique QR code, and the QR code contains information unique to the outlet.

Users who wish to use this service download and install the mobile app on their smartphone 300, then use the app to connect to the central management server 500 and request the use of an IoT outlet. Requests the advertisement server 400 to transmit an advertisement so that the user can use the IoT outlet 100 when he or she watches the advertisement.

The smartphone 300 recognizes the QR code 200 of the outlet 100 to be used using an installed app, and then requests the central management server 400 to use the IoT outlet including QR information and user information. Send a message.

The advertising server 400 uses the user information transmitted to the central management server 500 to transmit a specific advertising link to the user's smartphone 300. The advertising server 400 stores advertisement information 410 requested by advertisers and advertisement link information 420 that can be viewed by clicking on the advertisement.

The central management server 500 manages information about the branch and unique information and user information about the outlet 100 delivered to the branch, and uses an IoT outlet containing QR information and user information from the smartphone 300. Upon receiving the request message, the advertisement server 400 is requested to transmit a specific advertisement link to the user's smartphone, and when the user watches a specific advertisement for more than a certain period of time, the IoT outlet 100 uses unique information to An IoT outlet use approval message is sent to (300). Branches can be various facilities such as cafes, saunas, libraries, hospitals, and theaters. Although the configuration of the advertising server 400 and the central management server 500 has been described separately, the central management server 500 may be configured to include the functions of the advertising server 400.

When the central management server 500 receives an IoT outlet use request message, it goes through an internal approval process to check whether the outlet is a registered outlet using the outlet-specific information included in the QR information. Once internal approval is completed, the advertisement server 400 is requested to transmit a specific advertisement link to the user's smartphone 300.

When a user watches a specific advertisement for more than a certain period of time, the app on the smartphone 300 transmits an advertisement viewing completion message to the central management server 500. When the central management server 500 receives the advertisement viewing completion message, it transmits an IoT outlet use approval message to the smartphone 300 using IoT outlet unique information.

The IoT outlet 100 has a built-in short-distance communication function and performs wireless communication with the smartphone 300. When an IoT outlet use approval message is received from the smartphone 300, the power in the OFF state is turned off using an internal switch. Switch to ON state to activate power supply.

The IoT outlet 100 includes a short-range communication unit 110, a power control unit 120, and an abnormality detection unit 130.

The short-range communication unit 110 performs short-range wireless communication with the smartphone 300. It is preferable to use Bluetooth.

The power control unit 120 is normally kept in an OFF state where power is not supplied, and when the short-range communication unit 110 receives an IoT outlet use approval message from the smartphone 300, it closes the internal switch to turn the IoT outlet 100 on. It is switched to the ON state, which activates the power supply to the plug plugged in for a certain period of time, and after a certain period of time, the switch is opened again and switched to the OFF state, which blocks the power supply to the plug plugged into the IoT outlet 100. For example, when a user watches an advertisement for more than a certain period of time and receives an IoT outlet use approval message from the smartphone 300, the power control unit 120 closes the switch for 1 hour to switch to the ON state to activate power supply. After 1 hour, open the switch again and change it to the OFF state to cut off the power supply. The time at which the IoT outlet 100 closes the switch and activates the power can be remotely changed using the outlet's unique information in the central management server 500. If the user wishes to continue using the IoT outlet 100, he or she must view additional advertisements. Viewing additional advertisements is explained in detail below.

The central management server 500 is equipped with a mobile phone information unit 510 and an outlet information unit 520.

The mobile phone information unit 510 stores the user's mobile phone information, such as phone number and unique identification number, and the user's personal information.

The outlet information unit 520 manages information unique to the IoT outlet 100 registered at the branch, such as the serial number of the outlet.

After the advertisement server 400 transmits an advertisement to the user's smartphone, the central management server 500 informs the user of how much the IoT outlet can be used by sending time information to the user's smartphone when the advertisement 320 is viewed. Video advertisements transmitted from the advertising server 400 can be produced in about 3 minutes, and the central management server 500 notifies that if the user watches more than 60% of the advertisement, the IoT outlet can be used for 1 hour.

The app 310 of the smartphone 300 includes an outlet use request unit 311 that transmits an advertisement viewing completion message to the central management server 500 when the user clicks on the advertisement 320 and watches it for a certain period of time.

When the central management server 500 receives an advertisement viewing completion message from the app 310 on the smartphone 300, the central management server 500 has an IoT outlet use approval unit 530 that transmits an IoT outlet use approval message to the app 310 on the user's smartphone. Includes.

When the app 310 of the smartphone 300 receives the IoT outlet use approval message from the IoT outlet use approval unit 530, it transmits the IoT outlet use approval message to the IoT outlet 100 and sends the IoT outlet use approval message to the IoT outlet 100. The power control unit 120 switches to the ON state to activate power supply to the outlet.

The central management server 500 further includes an advertisement classification unit 540 and an advertisement viewing confirmation unit 550.

The advertisement classification unit 540 classifies the advertisement list stored in the advertisement server 400 into categories. The advertising server 400 stores various types of video advertisements requested by advertisers, and the advertising classification unit 540 uses information about various types of video advertisements stored in the advertising server 400 to advertise restaurants for each advertisement. , the list is classified and stored according to categories such as accessory advertisements, resort advertisements, electronic device advertisements, beauty advertisements, cafe advertisements, and delivery food advertisements.

The advertisement viewing confirmation unit 550 determines the advertisement viewing status for each user by checking which category the advertisement viewed by the user belongs to. The user can use the IoT outlet 100 while using various branches that provide this service. The number of advertisements for each category viewed by the user and the ratio of each advertisement category among all advertisements viewed by the user are identified and updated. For example, the total number of advertisements that users have watched so far is 40, and among them, 20 restaurant advertisements, 5 electronic device advertisements, and 15 beauty advertisements are used to determine the advertisement viewing status for each user.

The central management server 500 further includes an advertisement viewing time check unit 560 and an advertisement interest analysis unit 570.

The advertisement viewing time check unit 560 checks the time from when the app 310 on the user's smartphone starts watching the advertisement until it ends and sends it along with the advertisement viewing completion message to determine whether the user has watched the advertisement for more than a certain amount of time set by the server. Check the advertising viewing time. The central management server 500 determines whether the user has completed watching the advertisement by checking whether the user has watched more than 108 seconds, which is 60% of the 3-minute advertisement. Users may watch the advertisement for more than 60% of the standard time and stop watching the advertisement immediately, but if the advertisement is of interest to them, they may watch the entire 3 minutes.

The advertising interest analysis unit 570 analyzes advertisements of interest to each user based on the user's viewing time for each advertisement. The total number of advertisements that the user has watched so far is 40, and among them, 20 restaurant advertisements, 5 electronic device advertisements, and 15 beauty advertisements have been viewed. Assuming that the user has viewed 20 advertisements, 60% of the time), a more specific analysis shows that most electronic device advertisements were viewed by users slightly more than a certain amount of time, but more than 12 out of 20 restaurant advertisements were viewed more than a certain amount of time. It can be confirmed that more than 90% of the total advertising time was viewed, and more than 9 out of 15 beauty advertisements exceeded the certain time limit, making it possible to check whether 90% of the total advertising time was viewed. In other words, the IoT outlet 100 can be used even if more than 60% of the advertisement time set by the server is viewed. However, if an advertisement corresponding to 90% of the total advertisement time is viewed, it is classified as an advertisement of interest to the user. The above user is analyzed as a user who is not interested in electronic device advertisements, but is very interested in restaurant advertisements and beauty advertisements.

The central management server 500 further includes an advertisement matching unit 580.

The advertisement matching unit 580 analyzes the business type of the branch and the user's advertisement viewing time, matches the advertisement with a good response from the user using the branch, and requests the advertisement server 400 to transmit the advertisement to the user's smartphone. .

Cafes will be mainly used by young customers in their 20s and 30s, Jjiljilbang will be used by female customers in their 30s and 50s, and beauty businesses such as nail art will be used by female customers in their 30s and 40s. And the study cafe will be mainly used by young customers in their 10s to 30s. As explained above, by analyzing the advertisement viewing time for each user, it is possible to analyze which advertisements each user is most interested in. Statistical analysis of advertisements of interest by user allows cluster analysis of which advertisements customers using the branch are most interested in by business type.

Here, information on the branch the user is currently using is additionally reflected to exclude advertisements that overlap with the branch currently in use and the industry. As a result of cluster analysis, female customers in their 30s are interested in beauty advertisements and restaurant advertisements. Currently, if a user wants to use the IoT outlet (100) for nail art, one of the restaurant advertisements excluding the beauty advertisement to which the nail art currently being used is matched is matched. Thus, a request is made to the advertising server 400 to transmit an advertisement. The advertising server 400 will transmit, among several restaurant advertisements, an advertisement for a restaurant geographically close to the branch the user is currently using.

As a result of cluster analysis, male customers in their 20s are very interested in electronic device advertisements and cafe advertisements. Currently, if a user wants to use an IoT outlet (100) in a café, one of the electronic device advertisements excluding the café advertisement is matched to the advertisement server (400). Request to send an advertisement to .

The central management server 500 further includes a follow-up advertisement matching unit 590.

If the user watches the first advertisement for a certain amount of time or more and the usage time of the IoT outlet expires, the follow-up advertisement matching unit 590 determines that the user using the branch may be interested in addition to the previously viewed first advertisement and sends the first advertisement A second advertisement for a different industry is transmitted, and when the user watches the second advertisement, the usage time of the IoT outlet is extended.

When a man in his 30s watches a delivery food advertisement at a cafe for 2 minutes and uses the IoT outlet 100 for 1 hour, the usage time of the outlet has ended, so the IoT outlet 100 opens a switch to cut off the power supply. When the power supply is cut off, the app 310 of the smartphone 300 notifies the user that the usage time of the IoT outlet 100 has ended and transmits an electronic device advertisement that may be of interest to the user. When a man in his 30s watches an electronic device advertisement for more than a certain period of time, an approval message for use of the IoT outlet is sent to the man's smartphone (300), allowing the user to use the IoT outlet for an extended period of time.

The advertisement matching unit 580 transmits the first advertisement that the customer using the branch will be most interested in, and the follow-up advertisement matching unit 590 transmits the first advertisement that the customer is interested in if the business type does not overlap with the branch the customer is using. After watching the first advertisement, a second advertisement corresponding to a different industry from the first advertisement with a high viewer rating is transmitted.

The purpose of providing follow-up ad matching is two-fold. (1) If the user needs power for the laptop and wants to continue using the IoT outlet 100, he or she will use the IoT outlet 100 by watching a follow-up advertisement. (2) However, after using the IoT outlet 100 for about an hour, there may be customers who no longer use the IoT outlet 100 and want to leave the branch to move to another location. At this time, the user is planning to leave the branch in a while and does not intend to use the IoT outlet 100 anymore, but is interested in a follow-up advertisement and may click on the advertisement to watch it. (1) is a case of watching a follow-up advertisement to use the IoT outlet 100, and (2) is a case of watching a follow-up advertisement because the user does not use the IoT outlet 100 but is interested in the advertisement itself.

As a result of the cluster analysis, it was explained above that it was possible to analyze which advertisements customers using the branch were most interested in by business type. The follow-up advertisement matching unit 590 provides advertisements that may be of interest to users using the branch, that is, advertisements for industries in which users are slightly less interested based on the advertisement viewing time compared to the advertisement viewed first, but have the next highest interest. says Additionally, it refers to advertisements that do not overlap with the branch or industry that the user is currently using.

According to the present invention having the above configuration, when a customer needs power to use a laptop, cell phone, etc. in a store, he or she can use the power from the outlet for free by watching an advertisement provided by the server for a certain period of time. Owners of active branches can generate advertising revenue through advertisements viewed by customers. In addition, the system analyzes, matches, and transmits advertisements that may be of interest to customers using the branch, so advertisers can also enjoy the effectiveness of advertisements.

Although the present invention has been described in detail with reference to preferred embodiments so far, those skilled in the art to which the present invention pertains can implement the present invention in other specific forms without changing its technical idea or essential features. The embodiments should be understood in all respects as illustrative and not restrictive.
