Description

SYSTEM AND METHOD FOR MONITORING DISABLED PARKING ZONE

The present invention relates to a system and method for enforcement of parking spaces for persons with disabilities. More specifically, it relates to a system and method for enforcement of a parking area for the disabled for controlling non-disabled vehicles to park in the parking area for the disabled.

The disabled parking area may mean a parking area exclusively for the disabled. The disabled-only parking area is an area in the parking lot created for the disabled or disabled, and can only be parked if a person with a walking disability is on board. The disabled-only parking area can have a wide parking space for easy passage and close to the entrance. Under the current law, if a vehicle without a disability sign is parked in a parking area for the disabled, the vehicle may be subject to a fine for negligence.

In this case, the term "disabled person" means a person with a walking disability, and may mean a person who has been granted permission to use a vehicle display for the disabled by a national institution. According to the current law, vehicles marked with a disabled car sign can use the disabled parking area, and general vehicles cannot use the disabled parking space.

Recently, as the protection of the rights and interests of the disabled is required, welfare facilities for the disabled are being expanded in various places such as buildings, toilets, elevators, stairs, and sidewalks.

Generally, in the case of a parking area for the disabled, an identification sign such as a logo for the disabled is drawn on the floor of the parking area through painting, indicating that the parking area is an area where only vehicles owned by the disabled can be parked.

However, due to the parking problem caused by many vehicles, some unethical ordinary drivers often park in the disabled-only parking area even though they are aware that the parking area is a disabled-only parking area.

Although many enforcement personnel are being put in to crack down on illegal parking in these parking areas exclusively for the disabled, it is difficult to detect illegally parked vehicles by monitoring countless parking spaces for the disabled nationwide. Despite this, there are many problems in which the rights and interests of the disabled are infringed because the disabled parking area cannot be used due to the illegal parking of the general public.

In addition, the main body 131 may supply power to the notification unit 133 and control the notification unit 133 to display a predetermined expression (color, sound, etc.) to the outside.

The server 130 according to the present invention communicates with devices for communication inside the main body 131 , and may receive image data captured by the camera 132 . The server 130 may learn the image data and determine whether the vehicle V1 in the image data corresponds to the disabled vehicle based on the learned result.

The server 130 may generate parking state information of the disabled parking area based on the image data received from the camera 132 . The parking state information may include first information on whether the vehicle V1 parked in the disabled parking area exists and second information on whether the parked vehicle V1 corresponds to the disabled vehicle.

The parking state information may be generated through a vision recognition algorithm. First information on whether the vehicle V1 is parked in the parking area may be generated through the vision recognition algorithm. In addition, the first information may be generated using a specific sign for the parking area. That is, when a specific sign displayed in the parking area is not recognized, such as being obscured by the vehicle V1, it may be defined that the parked vehicle V1 exists in the current parking area.

A list of disabled vehicles may be stored in advance in the server 130 . The server 130 may compare the list with the vehicle number, and if they match, determine the parked vehicle V1 as a disabled vehicle. Conversely, the server 130 may determine that the parked vehicle V1 is not a disabled vehicle if the list and the vehicle number are not matched and there is a discrepancy.

When the non-disabled vehicle is parked in the disabled parking area, the server 130 may extract the vehicle number of the parked vehicle V1 from the image data, and generate an illegal vehicle list based on the extracted vehicle number. The illegal vehicle list may be transmitted to a separate external server (police server, etc.). If the license plate number of the non-disabled vehicle parked in the disabled parking area already exists in the illegal vehicle list, the server 130 extracts the number of times registered in the illegal vehicle list, and extracts the extracted number of times together with a separate external server (police server) etc.) can be transmitted.

4 is a view showing a camera according to the present invention.

According to FIG. 4 , the camera 132 of the present invention may include a camera module 1320 . The camera module 1320 may generate a video image from the optical image. The camera module 1320 may include a housing including a through hole in a sidewall, a lens 1321 installed in the through hole, and a driving unit 1323 for driving the lens 1321 . The through hole may be formed in a size corresponding to the diameter of the lens 1321 . The lens 1321 may be inserted into the through hole.

The driving unit 1323 may be configured to control the lens 1321 to move forward or backward. The lens 1321 and the driving unit 1323 may be connected in a conventionally known manner, and the lens 1321 may be controlled by the driving unit 1323 in a conventionally known manner.

In order to obtain various video images, the lens 1321 needs to be exposed to the outside of the camera module 1320 or the housing.

In particular, since the camera 132 according to the present invention has to directly photograph the first area A1, it must be located outside the housing, so a lens with strong contamination resistance is required. Accordingly, the present invention is to solve this problem by proposing a coating layer for coating a lens.

Preferably, the lens 1321 may include an acrylic compound represented by the following Chemical Formula 1 on its surface; It may be coated with a coating composition containing an organic solvent, inorganic particles and a dispersing agent.

[Formula 1]

here,

n and m are the same as or different from each other, and are each independently an integer from 1 to 100,

L ₁ is a biphenylene group.

When the lens 1321 is coated with the coating composition, it can exhibit excellent water repellency and stain resistance, so even if the lens 1321 installed outside the vehicle is exposed to a polluted environment for a long time, images or images that can be used as road information are collected. can do.

The inorganic particles may be selected from the group consisting of silica, alumina, and mixtures thereof. The average diameter of the inorganic particles is 70 to 100 μm, but is not limited to the above example. After the inorganic particles are formed as a coating layer 1322 on the surface of the lens 1321 , physical strength may be improved, and the viscosity may be maintained within a certain range to increase moldability.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited thereto.

As the dispersant, a polyester-based dispersant may be used, and specifically, as a polyester-based dispersion stabilizer composed of a copolymer of 2-methoxypropyl acetate and 1-methoxy-2-propyl acetate, TEGO-Disperse 670 (manufacturer : EVONIK), but not limited to the above examples, and any dispersing agent obvious to those skilled in the art can be used without limitation.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, etc., but is not limited to the above examples and may be used without limitation.

For forming the coating layer 1322, the coating composition may include, more specifically, an acrylic compound represented by Chemical Formula 1; organic solvents, inorganic particles and dispersants.

The coating composition may include 40 to 60 parts by weight of the acrylic compound represented by Chemical Formula 1, 20 to 40 parts by weight of inorganic particles, and 5 to 15 parts by weight of a dispersant based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component has a critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost absent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when applied to the surface of the lens 1321, it flows down and the formation of the coating layer 1322 is not easy, and it exceeds 1800 cP In this case, there is a problem in that the formation of a uniform coating layer 1322 is not easy.

[Preparation Example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing the acrylic compound represented by the following formula (1), inorganic particles and a dispersing agent in methyl ethyl ketone:

[Formula 1]

here,

n and m are the same as or different from each other, and are each independently an integer from 1 to 100,

L ₁ is a biphenylene group.

A more specific composition of the antistatic composition is shown in Table 1 below.

(unit parts by weight)

2. Preparation of coating layer

The coating composition of DX1 to DX5 was applied to one surface of the lens 1321 and cured to form a coating layer 1322 .

[Experimental example]

1. Evaluation of surface appearance

Due to the difference in viscosity of the coating composition, after the coating layer 1322 was prepared, a sensory evaluation was performed as to whether a uniform surface was formed. Whether or not a uniform coating layer 1322 was formed was evaluated, and evaluation was performed according to the following criteria.

○: uniform coating layer formation

×: Formation of a non-uniform coating layer

TX1 TX2 TX3 TX4 TX5 sensory evaluation Х ○ ○ ○ Х

When the coating layer 1322 is formed, when the viscosity is less than a certain level, a flow occurs on the surface of the lens 1321 , and after the curing process, it is difficult to form a uniform coating layer 1322 . Accordingly, there may be a problem in that the production yield is lowered. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition to form a uniform coating layer 1322 .

2. Measurement of water repellency angle

After forming the coating layer 1322 on the surface of the lens 1321, the results of measuring the water repellency angle are shown in Table 3 below.

)advancing contact angle (

) stop contact angle (

) receding contact angle (

) TX1 117.1±2.9 112.1±4.1 < 10 TX2 132.4±1.5 131.5±2.7 141.7±3.4 TX3 138.9±3.0 138.9±2.7 139.8±3.7 TX4 136.9±2.0 135.6±2.6 140.4±3.4 TX5 116.9±0.7 115.4±3.0 < 10

As shown in Table 3, after forming the coating layer 1322 using the coating composition of TX1 to TX5, the result of measuring the contact angle was confirmed. For TX1 and TX5, the receding contact angle was measured to be less than 10 degrees. That is, when it is out of the optimal range for preparing the coating composition, it was confirmed that a phenomenon in which water droplets are pinning occurs. On the other hand, it was confirmed that the peening phenomenon did not occur in TX2 to 4, thereby exhibiting an excellent waterproof effect.

3. Pollution resistance evaluation

The lens 1321 having the coating layer 1322 formed according to the embodiment on the outside of the facility was attached to the model camera, and exposed to the driving environment on a general road for 4 days. As the comparative example (Con), the same lens 1321 on which the coating layer 1322 was not formed was used, and in each embodiment, the model camera was attached to the same position of the vehicle.

Thereafter, the degree of contamination of the lens 1321 before and after the experiment was evaluated as related, and for objective comparison, the result was evaluated as an index of 1 to 10 in comparison with the comparative example in which the coating layer 1322 was not formed. shown in In the following index, the lower the number, the better the stain resistance.

Con TX1 TX2 TX3 TX4 TX5 stain resistance 10 7 3 3 3 8

(Unit: Index)

Referring to Table 4, when the coating layer 1322 is formed on the lens 1321, the high contamination resistance is easily analyzed for a long period of time even when the lens 1321 is exposed to the outside while the camera is installed in an external environment. It can be seen that image data can be collected. In particular, in the case of TX2 to TX4, it can be seen that the stain resistance by the coating layer 1322 is very excellent.
