Description

Outdoor advertising management system using Zigbee {OUTDOOR SIGNBOARD MANAGE SYSTEM USING ZIGBEE}

The present invention relates to an outdoor advertisement management system, and more particularly, to an outdoor advertisement management system that can quickly identify whether a plurality of outdoor advertisements are licensed in a ZigBee manner.

In the present specification, the outdoor advertisement is defined as referring to various types of signboards mainly installed on the outer wall and roof of a shopping mall building, and does not include a large display board installed to display contents. Since these outdoor advertisements have a great influence on the aesthetics of the city and the safety and convenience of pedestrians, local governments manage outdoor advertisements through the licensing system for outdoor advertisements. However, unregistered signboards and illegal signboards that deviate from the standard are still struggling, and the need for detection and corrective measures for unregistered outdoor advertisements has been discussed. There is a situation.

Accordingly, various systems and methods have been proposed for the efficient crackdown of illegal outdoor advertisements. For example, Korean Patent Registration No. 10-0566392 "Signage Information Management System and Method Using RFID", and Korean Patent Registration No. 10-0670217 "Signage management system and method using RFID-equipped building license plate", Republic of Korea Patent Registration No. 10-755431 "Outdoor advertising information automatic inquiry terminal and inquiry system and method using it", Republic of Korea Patent Registration No. 10-0847002 "Outdoor advertising information automatic inquiry terminal, the inquiry system and the method using the same" and the like.

As pointed out in the listed patent documents, patent inventions using RFID tags have a very limited recognition distance by using passive tags. As shown in FIG. 1, a number of signboards are suspended in one shopping mall building, and the number of floors is also varied, which makes the system ineffective using an RFID tag.

Instead of attaching a tag to each sign, the RFID invention is attached by building unit, and then based on the information read from the building tag, a list of outdoor advertisements registered to be attached to the building is provided. It's hard to see it work less. This is because a crackdown official will have to visually compare the information listed on the terminal with the actual signs installed in order to distinguish the unregistered outdoor advertisements. If so, this patent invention is merely to provide an improved method of providing information of outdoor advertisements registered in a building, so it is difficult to suggest an efficient method of crackdown. This problem also applies to the patent invention whose main content is to obtain the outdoor advertisement information of the building by inputting the building number into the PDA.

In conclusion, the conventional patent inventions in the art have their own efficient methods, but it is difficult to see them helpful in the actual work progress.

The present invention has been made in view of the above problems, it is an object of the present invention to be able to quickly investigate the number of outdoor advertisements.

The above object is an outdoor advertisement management system of the present invention, comprising: a response module that is separately mounted to an outdoor advertisement and can transmit and receive various information including unique registration information of the outdoor advertisement by Zigbee communication; And first broadcasting the request for transmission of the unique registration information to the unspecified outdoor advertisements using Zigbee communication, and when the reception error occurs due to interference between the unique registration information transmitted from the outdoor advertisement, the unspecified outdoor advertisements. A management terminal for secondly broadcasting a request for transmitting the unique registration information using Zigbee communication to compare the unique registration information normally received in response to the first and second broadcasting with the previously stored registration data to authenticate the management terminal. It can be achieved by an outdoor advertising management system characterized in that it comprises.

Here, when a reception error occurs in the response of the secondary broadcasting, the management terminal broadcasts a request for transmission of the unique registration information to the unspecified outdoor advertisements by using Zigbee communication, and performs the primary and The unique registration information normally received in response to the secondary broadcasting together with the unique registration information normally received in response to the third broadcasting may be compared with the registration data to authenticate.

In addition, when a reception error occurs due to channel interference, the management terminal broadcasts a channel change, a PN code change, and a request for retransmission of the unique property information, and in response, the response module transmits a request of the channel and the PN code. At least one may be changed to retransmit the unique registration information.

The present invention can solve the collision problem caused by a large number of unspecified outdoor advertisements sharing a few channels by providing an efficient operation method of one-to-many communication by the Zigbee communication method. Thus, error correction due to channel interference is solved in a simple manner.

In addition, although the present invention can achieve the above-described effects, by removing the network equipment such as servers, GPS equipment, video equipment, etc. to lower the system complexity of the operating equipment and to reduce the manufacturing cost, it is possible to practical use and commercialization .

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a shopping mall building commonly seen in the vicinity. 13 stores are located in the simplified mall building of Figure 1, it can be seen that there are a total of 22 outdoor advertisements installed there. Even if a crackdown official checks the list of registered outdoor advertisements against the 22 signs, it is difficult to immediately distinguish illegal outdoor advertisements. In that sense, the registered outdoor advertisement list information does not seem to help the enforcement directly.

2 shows a schematic connection relationship of an outdoor advertisement management system according to an embodiment of the present invention.

Referring to FIG. 2, the outdoor advertisement management system of the present invention is largely comprised of a management terminal 10 carried by a public official in charge and a response module 20 separately installed on a registered outdoor advertisement.

The management terminal 10 and the response module 20 communicate in a ZigBee manner. ZigBee is an IEEE 802.15.4 standard specification characterized by low power, small size, and low cost, as is well known. Network is known to be a suitable protocol for rare systems. More specifically, the 2.4GHz frequency band, 16 channels, 250kbps transmission speed, 6dBm transmission output, DSSN modem method, etc., it is known that it can operate for about one year with one battery.

A schematic internal block diagram of the management terminal 10 shown in FIG. 2, according to an embodiment of the invention, is shown in FIG.

Referring to FIG. 3, the management terminal 10 includes a communication unit 11, a user input unit 12, a memory 13, a display unit 14, a photographing apparatus 15, and a management control unit 16. .

The communication unit 11 is composed of a Zigbee-type antenna capable of transmitting and receiving, a chipset including a demodulator, an encoder, a decoder, and the like, and the user input unit 12 receives a command from a user by using a touch pad, an input button, or the like. Can be implemented.

The memory 13 is for storing registration information of pre-registered outdoor advertisements, and may be implemented as a nonvolatile memory having a number of GBytes, and the display unit 14 is for displaying various information for an interface with a user. It comprises a LCD panel and a driving circuit.

The photographing apparatus 15 is for capturing a state when illegal outdoor advertisements are visually identifiable as described below, and may be implemented as a low-cost camera apparatus based on a CMOS image sensor. In another embodiment of the present invention, the photographing apparatus 15 may be provided independently of the management terminal 10. Since the portable digital camera, the camera mounted on the mobile phone, and the like are widely used, the management terminal 10 is provided. It would be more desirable to exclude the camera device.

The management controller 16 is for overall operation of the management terminal 10, and performs user commands input through the user input unit 12, outdoor advertisement registration information and memory 13 input through the communication unit 11. Various functions are performed, such as determining whether the registered information previously stored is matched, controlling an imaging function of the photographing apparatus, and providing information to be displayed through the display unit 14. However, it will be appreciated that the management controller 16 can be sufficiently implemented using a low cost microprocessor.

Next, with reference to FIG. 4, a schematic internal block diagram of the response module 20 shown in FIG. 2 according to an embodiment of the present invention will be described.

The response module 20 includes a transceiver 21, a memory 22, a light emitting lamp 23, and a response controller 24.

The transceiver 21 is paired with the communication unit 11 of the management terminal 10, and is configured to include a Zigbee communication module. In particular, the transceiver 21 may select any of 16 channels allowed in ZigBee to transmit data, and optionally select one of a predetermined one or several PN codes to transmit data. This is to retransmit after changing the channel and / or PN code in order to solve a transmission error caused by channel interference or the like caused by one-to-many communication as described below.

The memory 22 is for storing registration information of pre-registered outdoor advertisements, wherein the registration information is defined to include minimal identification information, for example, an ID number.

The light emitting lamp 23 may be implemented as any one of various lighting lamps such as a high-brightness LED, a light bulb, a fluorescent lamp, or an explosion-proof lamp that emits specific color light. The light emitting lamp 23 is provided for the identification of the registered outdoor advertisement by the operator of the management terminal 10, and remotely turns on to visually identify an unregistered illegal outdoor advertisement when multiple outdoor advertisements coexist. Or flashing control.

The response controller 24 is for executing a command from the management terminal 10 input through the transceiver 21. For example, when the registration information of the outdoor advertisement is requested, the response controller 24 receives data stored in the memory 22. 21), the light emitting lamp 23 is turned on for a predetermined time or when a light command is received when the light emitting lamp 23 is requested to be turned on, and a channel is changed in case of a data transmission error due to channel interference. Control data retransmission.

Now, a method of operating an outdoor advertisement system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The outdoor advertisements permitted to be installed in the local government are given registration information, for example, an ID number, and stored in the memory 22 of the response module 20 and then mounted at an arbitrary position of the outdoor advertisement. Furthermore, the registration information is managed through the computer of the local government and stored in the management terminal 10 of the crackdown official.

It is assumed that a crackdown official (hereinafter referred to as a "user") conducts crackdown activity in front of the mall building shown in FIG.

First, a user inputs a request for transmitting registration information through a user input unit 12 of the management terminal 10 in a broadcasting manner, and accordingly, the management control unit 16 transmits the request command in a broadcasting manner. 11). That is, the same request information is transmitted through all channels (eg, 16) used in Zigbee, and these commands are transmitted in a direct sequence spread spectrum (DSSN) scheme according to a predetermined PN code.

The response module 20 mounted to the outdoor advertisement at a position where it can be received responds to the request by transmitting registration information stored in the memory 22. At this time, each response module 20 randomly selects any one of the available channels and transmits data, and / or transmits registration information by using a randomly selected PN code among one or several predetermined PN codes.

The communication unit 11 of the management terminal 10 extracts the registration information received through each channel through a demodulation and decoding process. Descriptions used for restoring registration information, such as demodulation for each channel and decoding process based on a predetermined PN code, are well known in the CDMA art, and thus detailed descriptions thereof will be omitted.

Next, the management control unit tests whether the received and extracted registration information matches the registration information previously stored in the memory 13.

The registration information determined to match is visually provided to the user through the display unit 14. On the other hand, if there is a mismatch registration information as a result of the test or if it is determined that the proper registration information has not been extracted despite the information received through the channel, the management control unit 16 requests the channel change and retransmission of the registration information. Transmit by broadcasting method.

All response modules 20 responding to this randomly select a channel and / or PN code and then retransmit the registration information to the management terminal 10. As described above, the PN code is determined to select from one or several predetermined codes, and the change of the channel and the change of the PN code can be changed simultaneously or only one.

This is to solve a data transmission error that occurs when a plurality of response modules 20 transmit the registration information through the same PN code through the same channel. Attention has been paid to the fact that the response modules 20 which caused the collision are very unlikely to cause a collision. Therefore, it is possible to correct the data reception error by maintaining registration information verified as a result of the first test and adding newly confirmed registration information after the second.

Now, a secondary test is performed to see if the registration information received secondly matches the registration information stored in the memory 13 again.

If all registration information is determined to match, all the results are displayed on the display unit 14, or on the display unit 14 by adding the confirmed registration information in addition to the primary result.

If there is a discrepancy between the registration information that is still received and the previously stored registration information even in the second test result, it is assumed that there is information transmission in the same channel / PN code, and the channel and / or PN code change and request for retransmission of the registration information. do.

If the third test results still show inconsistencies between the received registration information and previously stored properties, you can request a channel and / or PN code change and retransmission of the registration information for the fourth test, The results may be confirmed by appending the newly confirmed registration information to the registration information verified through the first and second tests. This is because, considering the density of outdoor advertisements and the number of channel / PN codes, there is a very small probability that the same response module 20 will continue to generate errors despite changing the channel and PN codes. Therefore, it may be reasonable to correct the transmission error due to one-to-many wireless communication by finally confirming the registration information received at the level of the second or third test degree.

Next, the management control unit 16 may specify the outdoor advertisement designated by the user through the user input unit 12 or may perform a request to turn on the light emitting lamp 23 for all the outdoor advertisements which have been registered and confirmed.

Accordingly, it is possible to visually confirm that the light emitting lamp 23 is lit on all or part of the user-specified registered outdoor advertisements among the 22 outdoor advertisements shown in FIG. 1.

If the light emitting lamp 23 is lit in all the outdoor advertisements which have been registered, illegal outdoor advertisements in which the light emitting lamp 23 is not lit will be easily distinguished by the naked eye.

Such a state may be photographed by the photographing apparatus 15 and used as the basis for administrative disposal, and later, the government may return to the local government to extract only illegal outdoor advertisements through image editing on an image processing apparatus such as a personal computer. It is possible.

The management terminal 10 according to the embodiment of the present invention uses the low-capacity memory 13 and, in order to minimize system complexity, excludes a device for wireless connection with an external server or a network, and performs GPS function and image analysis. And an image comparison device. Nevertheless, since the management control unit automatically corrects signal interference and transmission errors due to one-to-many communication at a long distance, it is possible to increase user convenience and reliability. In addition, through the lighting of the light emitting lamp 23 there is an advantage that the public official in charge can easily check the illegal outdoor advertisements with the naked eye.

It will be understood by those skilled in the art that various modifications, substitutions, and the like are possible without departing from the spirit of the present invention.

For example, although the method of operating the system according to the embodiment of the present invention described above is described as having a time series order, it does not have to proceed in such an order unless it is to be logically preceded / followed up. .

In detail, the command to turn on the light emitting lamp 23 may be independently performed by only a user's selective command input. That is, the response module 20 may transmit the command in a broadcasting manner to perform the received command. It can be. In other words, the user may omit the procedure of checking whether the registration information stored in the memory 13 and the received registration information match and display the display information, and may independently instruct only to turn on the light emitting lamp 23 for visual identification. Such operating method is within the scope without departing from the spirit of the present invention.

In addition, although not shown, it is possible to extract only outdoor advertisements in which the light emitting lamp 23 is not turned on through an image processing apparatus such as a user's personal computer. It will be understood by those skilled in the art that such an image processing technique may be possible through input of a method of identifying the color, shape, etc. of the light emitting lamp 23 or a partial deletion command of the user.

Therefore, the technical idea of the present invention is not limited to the above-described embodiment of the present invention, and the protection scope of the present invention should be considered to be extended to the equivalent range based on the claims below.
