In FIG. 1, a gate management system according to an embodiment of the present invention includes an indoor intercom unit 1, an outdoor intercom unit 2, a database 3, and an electric lock 4.

The indoor intercom unit 1 is usually
It is provided inside the gate or in the room, and has a function of notifying that there is a person who wants to enter or enter the room. Recently, a small liquid crystal display or the like is mounted on such an indoor intercom unit 1 and a video camera or the like is installed outside the gate in advance, so that an image of a person who wants to enter or enter the room can be displayed. it can.

The outdoor intercom unit 2 includes a fingerprint detection unit 21, a determination unit 22, and an authentication unit 23, and the authentication unit 23 is provided with the database 3.

The fingerprint detecting section 21 detects fingerprint information of a person who wants to enter or enter a room, and is provided in a push button for requesting a lock or informing the user indoors that he is a visitor. Also, the fingerprint detection unit 21
Is stored in the database 3.

The determination section 22 determines whether the fingerprint information of the fingertip placed on the fingerprint detection section 21 is a bare finger (finger not covered with gloves or the like) or a finger (finger covered with gloves or the like). Is determined at the same time as whether the finger is a real finger.

When the determining unit 22 determines that the finger placed on the fingerprint detecting unit 21 is a real finger, the authenticating unit 23 compares the fingerprint information detected by the fingerprint detecting unit 21 and stored in the database 3 with the fingerprint information. An authentication process is performed with fingerprint information of a person who is allowed to enter or enter the room in advance. If the authentication results match, the authentication unit 23 sends an unlock signal for unlocking the gate to the electric lock 4 described later.

As described above, the database 3 is for storing the fingerprint information detected by the fingerprint detecting unit 21 for a certain period. For example, if a burglar or the like rings the interphone and confirms that no one is inside the building and the theft occurs, fingerprint information when the push button provided on the interphone is pressed is registered in the database 3. Therefore, it has the effect of being useful for an early solution.

The electric lock 4 includes an indoor intercom unit 1, an authentication unit 23 of the outdoor intercom unit 2,

The density distribution image generation section 232 measures the density distribution in the temperature distribution image generated by the temperature distribution image generation section 231 and generates the measurement result as a density distribution image.

The blood vessel pattern recognition unit 233 uses the temperature distribution image generation unit 23 to determine the portion of the grayscale distribution image generated by the grayscale distribution image generation unit 232 that is measured as dark.
1 is a portion where the temperature is measured to be high. That is, the blood vessel is measured as having a higher temperature than the surrounding part due to the blood flow flowing through the blood vessel. Therefore, the blood vessel pattern recognition unit 233 recognizes that the portion of the grayscale distribution image measured as dark is a blood vessel.

For example, in the temperature distribution image generated by the temperature distribution image generation unit 231, the measured temperature is measured to be substantially uniform, and in the density image generated by the density distribution image generation unit 232, When the shading is substantially uniform, the blood vessel pattern recognition unit 233 recognizes that there is no blood vessel pattern. Therefore, the subsequent authentication processing by the authentication unit 23 is not performed, and the fingerprint information of the fingerprint detection unit 21 is again processed. A notification to the effect that the detection process will be performed is given to the applicant. This notification is performed by providing a display unit for displaying character information, a speaker for outputting an audio signal, and the like on the outdoor interphone unit 2.

FIG. 3 is a flowchart showing an operation example of the outdoor intercom unit in the embodiment of the present invention. In FIG. 3, first, it is determined whether or not a fingertip is placed on the fingerprint detection unit 21 (step S31). If the fingertip is not placed, the process is continued until it is determined that the fingertip is placed.

In step S31, the fingerprint detecting section 21
When it is determined that the fingertip is placed on the fingertip, the temperature distribution image generation unit 231 irradiates the fingertip with infrared light,
A temperature distribution image is generated (Step S32).

Next, the density distribution in the temperature distribution image generated by the temperature distribution image generation section 231 is measured by the density distribution image generation section 232 to generate a density distribution image (step S33).

Next, in the grayscale distribution image generated by the grayscale distribution image generation unit 232, the blood vessel pattern recognition unit 233 is used.
It is determined whether or not there is a blood vessel pattern (step S34).

In step S34, when the grayscale distribution image generated by the grayscale distribution image generation unit 232 is uniformly distributed at a low temperature, it is determined that no blood vessel pattern exists. In addition, even if the grayscale distribution image is around 35 to 40 degrees, if the temperature distribution is uniform, the finger may be a warm replica (fake) finger, and similarly, there is no blood vessel pattern. Is determined.

In step S34, when it is determined by the blood vessel pattern recognition unit 233 that there is no blood vessel pattern in the grayscale distribution image (step S34 / NO), the fingerprint detection unit 21 again sends a message indicating that a bare finger is to be placed. Information and / or audio information is output (step S35).

In step S34, when the blood vessel pattern recognition unit 233 determines that the blood vessel pattern exists in the grayscale distribution image (step S34 / YES), the authentication unit 23 executes the fingerprint collation processing (step S3).

If the fingerprint collation results match, an unlock signal is sent to the electric lock 4, and if not, an instruction signal for instructing the indoor intercom unit 1 to sound a ringing tone. Is sent.

FIG. 4 is a block diagram showing a first operation example of the present invention. FIG. 4 illustrates a case where the determination unit 22 determines that the fingerprint information detected by the fingerprint detection unit 21 is a bare finger (directly detected from a human body). Authentication unit 23
Reads the fingerprint information from the database 3 and performs a matching process with the fingerprint information of a person who has been permitted to enter in advance. If the fingerprint information matches the fingerprint information, nothing is performed on the indoor intercom unit 1 and the electric lock 4 transmits an unlock signal to unlock the gate. The electric lock 4 unlocks the gate based on the transmitted unlock signal. At this time, information such as the ID number, date, and time of the person who performed the collation processing is registered in the database 3 as a log.

FIG. 5 is a block diagram showing a second operation example of the present invention. FIG. 5 shows a case where the determination unit 22 determines that the fingerprint information detected by the fingerprint detection unit 21 is a finger covered with gloves or the like (not detected directly from a human body). The determination unit 22 calculates the presence or absence of a feature point, the ratio of a black and white image, and the like to the detected fingerprint information, and determines whether or not the fingerprint information has a fingerprint. If it is determined that it is covered, the entry requester is notified again of a re-input instruction to remove the gloves and the like and detect fingerprint information via a display unit or a speaker (not shown). The determination unit 22 continues the same processing until a bare finger is input.

FIG. 6 is a block diagram showing a third operation example of the present invention. FIG. 6 illustrates a case where it is determined that the authentication results by the authentication unit 23 do not match. Here, if it is determined that they do not match, it means that a person who is not permitted to enter is visiting, and thus an instruction signal for sounding a ringing tone is sent to the indoor intercom unit 1. The indoor intercom unit 1 sounds a ringing tone based on the instruction signal from the authentication unit 23, transmits an unlocking signal for unlocking the electric lock 4, after confirming the visitor by a person who is indoors, The gate is unlocked.

FIG. 7 is a block diagram showing a schematic configuration of a gate management system according to another embodiment of the present invention. In FIG. 7, a gate management system according to another embodiment of the present invention replaces the indoor intercom unit 1 in the above-described embodiment of the present invention with a home security system 11 and operates based on a control instruction from the home security system 11. The controlled device 12 to be controlled is connected.

The home security system 11 is usually installed for the main purpose of crime prevention.
It is also possible to manage the power of the main controlled device 12 in the home.

For example, by adding control instruction information different for each individual to the fingerprint information of a person permitted to enter, when it is determined that the fingerprint collation results match, the controlled object based on the control instruction information is determined. The operation of the device can be controlled.

More specifically, when an instruction to turn on the air conditioner is set as the control instruction information of a person who is permitted to enter, the result of the fingerprint verification processing performed by the person indicates that there is no match. If so, the electric lock 4 is unlocked and the power of the air conditioner is turned on.

The control instruction information can be registered as different information for each fingertip. For example, the control instruction information added to the fingerprint information of the thumb may be set to power on the air conditioner, and the control instruction information added to the fingerprint information of the index finger may be set to fill the bath.

The above-described embodiment is a preferred embodiment of the present invention, and various modifications can be made without departing from the spirit of the present invention.
