FIG. 1A is a plan view for explaining respective devices constituting a parking lot access control system according to the present invention, and vehicle recognition and transmission using the devices.
1B is a front view of a vehicle entering and exiting the parking lot access control system according to the present invention.
FIG. 2 shows a main configuration of a parking lot access control system according to the present invention.

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

FIG. 1A and FIG. 1B are a plan view and a front view for explaining each device constituting the parking lot access control system according to the present invention and the vehicle recognition and transmission using the same. FIG. The main configuration of the system is shown.

Hereinafter, with reference to FIGS. 1A, 1B, and 2, the configuration and functions of the parking lot access control system according to the present invention will be described in detail.

2, a parking lot access control system 100 according to the present invention includes a shut-off bar mounting sensor unit 110, a geomagnetic sensor 120, a shut-off bar operating unit 130, and a multi-sensor license plate input control unit 50a And a sticky body 50b.

1A, the shut-off bar mounting sensor unit 110 includes a distance sensor 111, a PIR sensor 112 (see FIG. And the RF sensor 113 are installed to detect the front direction of the entering and exiting vehicle C1. This is different from the conventional case where various sensors are installed in areas other than the shut-off bar 10.

In this case, the distance sensor 111 senses the distance to the front direction of the vehicle C1 entering and exiting the entry / exit road surface area 30. For example, an ultrasonic sensor can be used as the distance sensor 111 have.

Here, the entry / exit road surface 30 is a square-shaped area through which the vehicle C1 passes between the first and second pedestals 20a and 20b. And the like.

The ultrasonic sensor senses the distance by measuring the time taken to receive the reflected wave from the object by transmitting ultrasound with sharp direction to the object, and it can detect not only the vehicle but also other objects and people, Be sensitive to the environment, especially when there is a risk of malfunction due to light reflection or smooth surface.

The passive infrared ray (PIR) sensor 112 senses the heat emitted from the vehicle C1 or the human body in the area of the entry and exit surface 30 to detect the presence or absence of a pedestrian and the movement of the vehicle C1 or a human body at about 7 to 10 meters do.

The RF sensor 112 is a motion sensor that detects movement of people and objects using microwaves and accurately detects minute movements without being affected by external environment such as temperature, humidity, light, and dust.

The geomagnetic sensor 120 may be installed on the entrance road surface 30 or a side structure such as a wall or a pole so as to detect a change in the earth's magnetic field due to the movement of the vehicle C1 and use the output voltage The presence or absence of the vehicle C1, and the like.

In this case, by using the geomagnetic sensor 120 for detecting the vehicle C1, it is possible to detect the vehicle more accurately than when using a loop coil sensor, simplify the installation, and reduce the installation cost .

In other words, the disadvantages of the loop coil sensor are that the first construction method is cumbersome, the construction cost is excessive, the second construction takes a long time, and the exposure time is long. Thirdly, The detection range on the fourth and fifth roads is relatively short, which causes malfunctions; and fifth, the volume of the vehicle detector is large, which makes it difficult to carry out a large number of construction work in one space.

The geomagnetic sensor 120 is provided with one or a plurality of S1 to Sn at the bottom or left or right of the exit road surface 30 at a certain distance from the shutting bar 10 for more accurate detection of the vehicle C1 And can be used to detect the state of the vehicle C1 by matching the respective magnetic field change amounts sensed by the respective sensor nodes S1 to Sn.

Hereinafter, the features and advantages of the arrangement of the multiple sensors 111, 112, 113, and 120 will be summarized.

First, the sensors 111, 112, and 113 installed in the blocking bar mounting sensor unit 110 according to the present invention do not need to be spaced apart from each other because they have little interference with each other.

However, it is preferable to arrange the distance sensor 111 at the center of the shut-off bar 10 at a position corresponding to the middle of the width of the possible entry and exit road surface 30, which is an active sensor, Because of the nature of the sensor (IR, ultrasonic, for example), it should be detected from the front of the incoming vehicle to minimize the sensitivity degradation to the slope reflection.

Second, the geomagnetic sensor 120 may be installed on the floor of the moving path of the vehicle C1 or may be fixed to the side structure. In the case where the sensor is embedded in the floor, the maximum distance from the upper surface of the sensors S1- 1a, the distance between the sensors S1 to Sn and the vehicle C1 must be within 1.5 m to allow accurate detection when the vehicle is installed on the side of the entry / exit road surface 30 as shown in FIG.

Third, since the present invention uses multiple sensors 111, 112, 113 and 120 for detecting a vehicle, the following advantages are provided compared to the case of using a single sensor.

That is, by installing a plurality of sensors 111, 112, 113, 120 according to the present invention (installing a plurality of sensors on a shut-off bar + installing a geomagnetic sensor on the sides of the exit road surface or exit road surface) It is possible to detect a vehicle with a minimum of misrecognition by judging the detection results of various sensors in a complex manner without sensing it.

For example, a geomagnetic sensor (a geo-magnetic sensor or an earth's magnetic sensor) can detect a metal chain vehicle because it is a sensor that detects a change in a geomagnetic field by using a magnetoresistive element whose resistance value changes according to a change of a magnetic field, Malfunctions due to changes in the characteristics of metal parts other than vehicles such as bicycles and geomagnetism in the area may occur.

In order to improve this, it is possible to improve the detection accuracy of the vehicle by analyzing the results (for example, the distance to the target object, the size, etc.) detected by the plurality of sensors 111, 112 and 113 installed on the shut- have.

The blocking bar operation unit 130 recognizes the vehicle number of the stick fish 50b and the vehicle number of the vehicle C1 entering and exiting the road surface area 30 from the storage unit 180, The control unit 10 generates the unblocking signal to move the blocking bar 10 upward so that the vehicle C1 can pass.

Next, the multi-sensor license plate input control unit 50a includes an access vehicle photographing unit 140, a sensor signal processing unit 150, and a communication unit 160. [

Particularly, the multi-sensor license plate input control unit 50a, which is one of the core devices of the present invention, is installed in the body of the first cradle 20a together with the microcomputer equipped with the parking management unit 170 and the car number recognition and storage unit 180 And detects the vehicle entering / exiting information through the blocking bar mounting sensor unit 110 and the geomagnetic sensor 120, and controls the blocking bar actuating unit 130.

As shown in FIG. 1A, the entrance and exit vehicle photographing unit 140 includes a first entrance and exit vehicle photographing unit 140a installed on one side of the body of the first cradle 20a, And a second access vehicle photographing unit 140b provided on one side of the body of the second mount table 20b disposed on the opposite side of the first mount table 20a with the access road surface 30 interposed therebetween.

The first entrance and exit vehicle photographing section 140a and the second entrance and exit vehicle photographing section 140b photograph the front and rear faces of the vehicle C1 entering and exiting the exit road surface area 30, Based network camera or the like can be used.

The sensor signal processing unit 150 generates a sensor signal based on the sensing signals inputted from the distance sensor 111, the PIR sensor 112, the RF sensor 113 and the geomagnetic sensor 120 mounted on the blocking bar mounting sensor unit 110, Or not.

For example, when the distance sensor 111 senses the vehicle within a predetermined first reference value, the PIR sensor 112 transmits a first vehicle sensing signal. When the PIR sensor 112 senses the vehicle within a predetermined second reference value, The RF sensor 113 transmits a third vehicle detection signal when the vehicle senses the vehicle within a predetermined third reference value and the geomagnetic sensor 120 detects the vehicle within a preset fourth reference value The sensor signal processing unit 150 can determine whether the vehicle is entering the vehicle more accurately than when using a single vehicle detection signal based on the transmitted first to fourth vehicle detection signals .

Even if the geomagnetism sensor 120 fails, the sensor signal processing unit 150 determines whether or not the vehicle enters the vehicle based on the first to third vehicle detection signals transmitted by the remaining three sensors 111, 112, and 113 It is possible to accurately detect the vehicle irrespective of the failure of some vehicle detection sensors.

The distance sensor 111, the PIR sensor 112, the RF sensor 113, the geomagnetism sensor 113, the geomagnetism sensor 113, the geomagnetism sensor 113, A sensor mode switching unit (not shown) for switching the operation mode of the sensor 120 and the entrance vehicle photographing unit 140 from a wake-up mode to a sleep mode to realize a low- Sensor vehicle license plate input control unit 50a.

In this case, the sensor mode switching unit (not shown) immediately switches to the wake-up mode when the vehicle C1 enters and exits from the entering / exiting road surface area 30 even in the sleep mode, thereby controlling each sensor to exhibit its normal function.

The communication unit 160 provides an interface capable of performing communication with an external terminal. For example, the communication unit 160 can utilize Ethernet communication in a wired communication manner and can use a WiFi, a Zigbee, a Bluetooth, , RF (RF), 3G, 4G, LTE, LTE-A, and Wireless Broadband Internet, but the present invention is not limited thereto.

Lastly, the stick fish 50b includes a parking management unit 170 and a car number recognition and storage unit 180. [

The microcomputer such as a stick PC or a mini PC is installed in the breaker main body 100a and interlocks with the vehicle number recognizing unit 150 and the parking managing unit 170 built in the breaker body 100a, It uses the recognition and parking management function to provide the overall function of the parking access control system.

In addition, the stick PC or mini PC is different from a conventional PC, for example, a 1.33GHz Intel Atom processor that operates as a dual-core in the form of a tiny bar or box (Box) Performance built-in processor, built-in memory capacity of 2GB, internal storage capacity of 16 ~ 32GB, and the monitor is connected to the HDMI terminal, the same function as a normal PC.

Accordingly, the present invention can perform car number identification, storage, and communication using only a small stick PC without building a separate server.

If the vehicle number analyzed by the vehicle number recognition and storage unit 180 is unusual, for example, if the vehicle number is the stolen notification number, the parking management unit 170 transmits an alarm signal to the police station to quickly arrest the thief Or if the number is an unregistered number, an alarm may be generated to control the entry of the vehicle to the parking attendant, or a separate payment system may be used.

The vehicle number recognition and storage unit 180 includes a function of receiving and storing the vehicle image acquired by the entrance vehicle shooting unit 140 and a function of extracting the vehicle number by the vehicle number recognition engine 180a.

Here, the vehicle number recognition engine 180a searches the vehicle license plate first by applying a pattern analysis algorithm to the forward image of the blocking bar 10 acquired by the access vehicle photographing unit 140, (S / W) for extracting the data.

In this case, the extracted vehicle number is provided to the parking management unit 170 and utilized as parking management information. For example, the basic parking management service may include registered vehicle management, designated parking management, parking lot management, But is not limited to.

That is, in the case of the present invention, after storing the conventional photographed vehicle image in the server, the car number recognition result analyzed by the car number recognition engine is stored again in the server, and when there is a request from the user, Unlike the method of the first embodiment, real-time information of the access vehicle C1 is received in real time and analyzed in real time through the car number recognition engine 180a to recognize the car number in the field, , Smart phone, server, etc ..
