Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 is a block diagram illustrating a security system configuration of a medicine refrigerator according to the present invention.

Reference numeral 110 denotes a fingerprint recognition module installed at a predetermined position of the medicine refrigerator for recognizing a user's fingerprint. Fingerprint recognition is one of the biometric technologies (biomatrix), also known as fingerprint recognition system. Fingerprints are kept in the same shape until they die at birth, and even when they are damaged by external factors, they are reproduced in a conventional form, so the probability of having fingerprints of the same type as others is only one billionth. Fingerprint recognition technology refers to a technique of electronically reading a user's finger using these characteristics of a fingerprint and comparing the fingerprint with previously input data to identify the user and confirm the identity of the user.

There are two typical approaches: optical and silicon. The former is the most widely used method, in which strong light is projected onto a platen to reflect the shape of the fingertip placed on the platen, the image of the reflected fingerprint passes through a high refractive lens to convert the CCD A device that allows the device to be read. The latter utilizes the biologic features of the skin by using electrical conduction characteristics to directly touch the surface of the silicon chip to read the specific shape of the fingerprint that comes into contact with the chip surface as an electric signal.

Reference numeral 120 denotes an RFID authentication module installed at a predetermined position of the medicine refrigerator for authenticating RFID carried by a user. RFID is a non-contact recognition system that attaches a small chip to various goods and transmits and processes information of objects and surrounding environment information by radio frequency. This system, which has emerged since the 1980s, is also referred to as dedicated short range communication (DSRC) or radio identification systems. A radio identification system consisting of a reader with read / decode capability, an RF ID tag with built-in information, operating software, and a network processes the information by identifying the thin flat tag attached to the object.

RF tags consist of transponder chips and antennas made of semiconductors, and they are both manual and active. While the manual type operates by receiving energy from the reader's radio signal without internal power, the active type has an RF tag battery built in for its own operation. Chip tag using a silicon semiconductor chip, and a non-chip tag composed of an LC element or a plastic or polymer element. Low-frequency radio identification systems (30 kHz to 500 kHz) are used at short distances of less than 1.8 m and high-frequency systems (850 MHz to 950 MHz or 2.4 GHz to 2.5 GHz)

Reference numeral 130 denotes a temperature control board for controlling the temperature in the refrigerator to be maintained at a set temperature and detecting a current temperature and a temperature change in the refrigerator. The temperature control board 130 controls the current temperature, the set temperature, the DIV temperature, (RFID) authentication module 120, and controls the release and locking of the door lock according to the authentication of the fingerprint and / or the RFID. And a main control unit for controlling the information to be stored in the data storage unit such as the information of the door open person and the temperature change at the time of opening the door, and is preferably an ordinary microcomputer or a microprocessor and has a memory and a timer therein.

Reference numeral 160 denotes a data storage device for storing image information of a user generated during operation of the medicine refrigerator, temperature information of the refrigerator, set temperature information set by the user, DIV temperature information, fingerprint information, RFID information, Reference numeral 190 denotes a camera module for capturing an image of the manager when the fingerprint recognition or RFID authentication is performed, and acquiring image information and providing the image information to the main controller 150. The camera module 190 acquires image information that can be used as evidence information when the medicine is stored in the refrigerator or taken out of the stored medicine in the future.

Reference numeral 180 denotes a voice output module which responds to the control of the main control unit 150 to open the door of the medicine refrigerator for a predetermined time or send a warning message by voice in the event of a specific error, . ≪ / RTI >

Reference numeral 170 denotes a door lock for locking or unlocking the door of the medicine refrigerator. Reference numeral 200 denotes a keyboard connected to the main control unit 150 to change the information of the person to be fingerprinted or the RFID subject. Here, it is preferable to implement the keyboard 200 so that the keyboard 200 can be attached to the medicine refrigerator, and the administrator using the RFID or the fingerprint using the keyboard can register / modify / delete the information.

Reference numeral 140 denotes a display unit connected to the main control unit 150 for displaying current temperature, temperature change amount, fingerprint information, RFID information, stored image information and the like on the screen, and it is preferable to use a general liquid crystal display .

The operation of the security system of the drug refrigerator according to the present invention constructed as described above is as follows.

First, a keyboard 200 is connected to a connector provided at a predetermined position of the refrigerator in order to register a user (administrator) of the medicine refrigerator while the medicine is stored in the medicine refrigerator, so that the keyboard 200 and the main controller 150 (PS / 2) line, and performs registration, correction or deletion of the user through the keyboard 200. [

In the case of the user registration, the registration mode is set through the keyboard, and the user information is registered through the fingerprint recognition module 110 or the RFID authentication module 120. For example, when a fingerprint is used, a finger corresponding to the fingerprint to be registered is connected to the fingerprint input field. The fingerprint recognition module 110 scans the fingerprint image to extract a fingerprint image, 160). At this time, it is preferable that the user's information is provided through the keyboard and the fingerprint image is stored together with the user information (name, department, contact number, etc.).

Next, when the user is registered using the RFID, the registration mode is set through the keyboard in a state where the RFID card is already issued. When the RFID card is brought close to the reader, the reader reads the information recorded in the RFID card, (150). The main control unit 150 stores the provided RFID card information in the data storage 160 and registers it as a user. When the user information is registered using the RFID card, since the user information is already included in the information of the RFID card, it is not necessary to input the user information by using the keyboard.

Similarly, modification or deletion of user information is performed in the same manner as the above-described registration method, except that the mode (correction mode, deletion mode) is selected only through the keyboard.

In a state where the temperature of the medicine refrigerator is maintained at a predetermined temperature by the control operation of the temperature control board 130, the temperature control board 130 stores the current temperature, the set temperature, DIV temperature, time, and the like to the main control unit 150. The main control unit 150 stores the information in the data storage unit 160 so that the temperature change amount can be checked in real time.

On the other hand, when the user inputs fingerprint information through the fingerprint recognition module 110 or presents an RFID card (both of them can be used in parallel according to the user's needs) in order to fetch medicines stored in the medicine refrigerator, , And the entire process from door lock release to door locking of the medicine refrigerator is controlled by the main control unit 150.

For example, when the user provides the fingerprint information, the camera module 190 picks up the user who provided the fingerprint, stores the image information and the time information together in the data storage 160, Extracts the fingerprint image information of the user, compares the extracted fingerprint image information with the fingerprint image information registered in the data storage 160, and provides the comparison result to the main controller 150.

The main control unit 150 analyzes the comparison result, and when it is not the same, transmits an error message through the voice output module 180. Alternatively, when the input fingerprint information is already registered, the door control unit 170 controls the door lock 170, . At this time, it is also possible to display the door state by using a separate display device (for example, an LED) in the door lock 170. A user who wants to withdraw medication draws out necessary medicines after opening the door, and inputs the information through the keyboard 200. [ When the medicine is withdrawn, the main control unit 150 can check the withdrawn medicine, so that the stock management is performed through the inventory management function. At this time, since all processes of user's drug withdrawal are recorded by the camera module 190 and stored in the data storage 160, the retrieval information inputted by the user through the keyboard 200 and the drug withdrawn by the camera If the information is different, an error message can be generated and other administrators can confirm it.

In addition, since the camera can prevent the user from shooting the medicine when the user takes out the medicine, the weight sensor for weight detection is attached to the lower end of the medicine refrigerator in order to further improve the accuracy of drug withdrawal and inventory, It is possible to confirm whether or not the fetching information and the actually fetched medicine match with each other. This can be used to identify facts later if the user has misrepresented the withdrawal drug information or deliberately misrepresented it.

When the door is opened to withdraw the medicine, the temperature is sensed by the operation of the temperature control board 130 and stored in the data storage 160.

In addition, if the user does not close the door within a predetermined period of time while the door is opened to withdraw the medicine, there is a possibility that the medicine stored due to the temperature change of the medicine refrigerator may be altered. Accordingly, in order to prevent such a case, the main control unit 150 checks the door open time in conjunction with the door lock 170. When the door open time exceeds a preset time, the voice output module 180 The voice message is transmitted, and the corresponding information is stored in the data storage 160. [

In this process, it is possible to confirm the stored medicine information, the confirmation of the withdrawn medicine information, the retrieval person's image information, and the like through the display unit 140.

FIG. 2 is a flowchart showing a first embodiment of a security method for a drug refrigerator according to the present invention. This is the process of operating the drug refrigerator using fingerprint information.

As shown in the figure, the first embodiment of the security method for the refrigerator of the present invention checks whether the fingerprint information is inputted in the state where the medicine refrigerator is operated in step S101, and if the fingerprint information is not inputted, It is confirmed whether a specific error occurred during operation of the medicine refrigerator. If it is determined that a specific error has occurred, the process proceeds to step S105 to transmit a voice for the occurrence of a specific error. As a result, the user (manager) can know which part of the medicine refrigerator has an error.

Next, if the fingerprint information is input, the process proceeds to step S107 to photograph the fingerprint inputting person and stores the image information, and goes to step S109 to confirm whether or not the inputted fingerprint information is registered. If the fingerprint information is the unregistered fingerprint information, the error message is transmitted in step S111. If it is the registration fingerprint, the door lock is released in step S113 so that the user can open the door.

In a state in which the door lock is released, it is checked whether the door is opened in step S115. If the door is not opened, the process goes to step S117 and it is confirmed whether it is a user information change request. As a result of the confirmation, if the user information change (registration / deletion / modification) request is made, the canceled door lock is re-locked in step S119 and the user information is registered / corrected / deleted in accordance with the user's operation in step S121.

If it is determined in step S115 that the door has been opened, the internal timer is driven to check the door open time in step S123. In step S125, it is determined whether the door is closed. If it is determined that the door is not closed, the process proceeds to step S127 to check whether a predetermined time has elapsed. If the door is opened for the predetermined time, the door open error message is transmitted in step S129.

Otherwise, if the door is closed within a predetermined time, the process proceeds to step S131 to lock the door, and then proceeds to step S133 to generate and store user information and detail information. Here, the user information and the history information include user information for opening a door, a time when the door is opened, a temperature change amount of the medicine refrigerator, a medicine withdrawing amount, and the like.

FIG. 3 is a flowchart showing a second embodiment of a security method of a drug refrigerator according to the present invention. This shows the process of operating a drug refrigerator using RFID.

As shown in the figure, the second embodiment of the security method for the refrigerator of the present invention checks whether the RFID information is inputted in the state where the drug refrigerator is operated in step S201, and if the RFID information is not inputted, It is confirmed whether a specific error occurred during operation of the medicine refrigerator. If it is determined that a specific error has occurred, the flow advances to step S205 to transmit a voice for a specific error occurrence. As a result, the user (manager) can know which part of the medicine refrigerator has an error.

Next, if the RFID information is inputted, the process goes to step S207, the corresponding RFID input person is photographed to store the image information, and the process goes to step S209 to check whether the inputted RFID information is registered. If it is determined that the RFID information is unregistered RFID information, an error message is transmitted in step S211. If it is the registered RFID, the door lock is released in step S213 so that the user can open the door.

When the door lock is released, it is checked whether the door is opened in step S215. If the door is not opened, the process goes to step S217 and it is confirmed whether it is a user information change request. As a result of the confirmation, if the user information change (registration / deletion / modification) request is made, the canceled door lock is re-locked in step S219 and the user information is registered / corrected / deleted according to the user's operation in step S221 .

If it is determined in step S215 that the door has been opened, the internal timer is driven to check the door open time in step S223. In step S225, it is determined whether the door is closed. If it is determined that the door is not closed, the process proceeds to step S227 to check whether a predetermined time has elapsed. If the door has been opened for the predetermined time, the door open error message is transmitted in step S229.

Otherwise, if the door is closed within a predetermined time, the process proceeds to step S231 to lock the door, and then proceeds to step S233 to generate and store user information and detail information. Here, the user information and the history information include user information for opening a door, a time when the door is opened, a temperature change amount of the medicine refrigerator, a medicine withdrawing amount, and the like.

As shown in the figure, the third embodiment of the security method of the refrigerator of the present invention checks whether the RFID information is inputted in the state where the drug refrigerator is operated in step S301, and if the RFID information is not inputted, It is confirmed whether a specific error occurred during operation of the medicine refrigerator. If it is determined that a specific error has occurred, the flow advances to step S305 to transmit a voice about a specific error occurrence. As a result, the user (manager) can know which part of the medicine refrigerator has an error.

Next, if the RFID information is input, the process goes to step S307 to photograph the corresponding RFID input person, stores the image information, and goes to step S309 to confirm whether or not the inputted RFID information is registered. If it is the unregistered RFID information, it transmits an error message in step S311. If it is the registered RFID, it receives the fingerprint information in step S313 and confirms whether it is the registered equity information in step S315. If the fingerprint information is not the registered fingerprint information, the process proceeds to step S311 described above. Otherwise, the process proceeds to step S317 to perform the following steps. Here, steps S317 to S337 are the same as steps S113 to S113 of FIG. 2 or steps S213 to S233 of FIG. 3, so that detailed description will be omitted in order to avoid redundant description.
