Description

Parking sensor apparatus, parking service apparatus, parking service system using them, parking service method, and non-volatile recording medium in which computer programs for the parking service are recorded {Parking sensor apparatus, parking service apparatus and parking service system using them, and parking service method, and non-transitory computer readable medium having computer program for parking service method recorded thereon}

The present invention relates to a parking sensor device, a parking service device, a parking service system using the same, a parking service method, and a non-volatile recording medium on which a computer program for the parking service is recorded, and more particularly, a plurality of sensors including a geomagnetic sensor. A parking sensor device, a parking service device, and a parking service system using the same, a parking service method, and the parking service thereof, which increase the vehicle detection performance of the parking sensor device having a parking sensor device and increase reliability by managing independently managed sensor reference values so as not to be biased. It relates to a non-volatile recording medium on which a computer program for

There is a system for installing a parking sensor module including one or more sensors for detecting parking and departure of a vehicle on a parking surface, and managing parking for a vehicle by communicating with the corresponding parking sensor module.

Since the presence of a vehicle can be detected through such a parking sensor module, a parking service server that operates a parking lot in conjunction with the parking sensor module can determine the parking time of the vehicle and calculate and charge a parking fee.

However, since it is difficult to identify a parked vehicle with only the corresponding parking sensor module, there is a burden that requires additional management personnel or an additional system such as identifying a license plate of a vehicle by interlocking a camera.

Therefore, a function of wirelessly transmitting parking surface information has been added to the recent parking sensor module, and a terminal carried by a driver wirelessly receives the corresponding parking surface information and transmits the parking surface information and identification information of the terminal to the parking service server. configuration is being applied.

In this way, when the parking service server receives the parking surface and terminal identification information from the driver terminal, it can provide parking start information and parking fee settlement information according to departure to the corresponding driver terminal, even without a relatively expensive video analysis system or related personnel. Accurate vehicle parking management is possible.

However, since the existing parking sensor module detects a vehicle by operating a plurality of sensors and transmits only the result to the remote parking service server, it is difficult to verify whether the vehicle has been detected or not. In particular, some of the sensors may not operate normally for a certain period of time depending on the weather, the geomagnetic distribution of the installation area, the existence of heavy conductors in the adjacent area, and environmental influences such as rain, fog, moisture, and dew. Each parking sensor module determines whether some sensors malfunction due to the influence according to its own set algorithm, and uses the measured values of all sensors for vehicle detection or excludes the measured values of some sensors from the vehicle detection judgment. Therefore, there is a problem in that the reliability of the sensor malfunction determination of the parking sensor module, which determines the operating state of the sensor itself without additional information, is not high.

Furthermore, the conventional parking sensor module is biased or distorted because the sensor reference value for compensating the measurement value of each sensor or determining vehicle detection according to the installation environment is updated by the accumulation of measurement values that the corresponding parking sensor module recently detected the presence of a vehicle normally. It also happens that a set sensor reference value is set and continuously affects subsequent measurements.

In addition, since the parking sensor module is installed on the parking surface in a completely sealed state, the process of measuring the sensor, determining whether or not to detect the vehicle, and updating the sensor reference value is simplified as much as possible to reduce the consumption of the built-in battery. .

It is possible to control the sleep mode transition without updating the sensor reference value or updating the sensor reference value.

Meanwhile, when the control unit receives the sensor reference value information for update while receiving the vehicle detection result from the parking service server, the control unit provides the updated sensor reference value information to the reference value setting unit to update the sensor reference value for the corresponding sensor, and then sleep mode. You can also control the transition.

As an example, the control unit may cut off power to a configuration other than a preset monitoring mode operation configuration for switching to a sleep mode through a power management unit, and may switch itself to a low power sleep mode.

As an example, the reference value updating unit uses the average value of the latest information of adjacent parking sensor modules stored in the reference value management unit when the latest information of the specific parking sensor module to be stored in the reference value management unit has a deviation greater than the reference value. It can be corrected to approximate the average value.

As an example, the parking service server may further include an environment information collection unit that collects weather information about the area where the parking sensor module is installed and further provides the collected weather information to the vehicle determination unit.

Furthermore, the vehicle determining unit may classify a malfunctioning sensor using measurement values of each sensor of a specific parking sensor module and the meteorological information, and determine a change in existence of a vehicle using measurement values of normally operating sensors.

As an example, the vehicle determination unit may determine the vehicle presence/absence change state according to the measurement values of a plurality of sensors received through a deep learning neural network model that has learned the measurement values of each sensor of the parking sensor module and the vehicle presence/absence change result. there is.

When the up signal is received, the first sensor unit and the second sensor unit are operated to detect the vehicle, and if there is a valid value equal to or greater than the preset reference value for each sensor, the corresponding measured value is transmitted to the parking service server, and the vehicle detection result is received from the parking service server When the parking sensor module returns to the sleep mode and the measured values of the plurality of sensors of the specific parking sensor module are received, the change in the presence or absence of a vehicle is determined to determine the start and end of parking, and the and a parking service server that transmits the result of determining the change to the parking sensor module as a vehicle detection result.

There is an effect of determining the existence of a vehicle more reliably through an advanced judgment method such as using more or applying a deep learning model.

In addition, after the parking service server detects a change in the presence of a vehicle through the effective measurement value provided by the parking sensor module, when the existence of the vehicle has changed, the corresponding effective measurement value is accumulated and stored in correspondence with the parking sensor module, and the previously stored valid measurement value and If the deviation of is greater than the standard, the stored measurement value is corrected using the average of the last stored measurement values of other parking sensor modules disposed adjacent to the corresponding parking sensor module and stored instead, and the corrected measurement value is used as the sensor reference value for update.

This has the effect of reducing battery power consumption and increasing measurement reliability.

1 is an exemplary view of a parking lot 10 configured with a management target parking surface to which an embodiment of the present invention is applied. As shown, the parking surface 11 detects parking and departure of a vehicle and transmits it to a remote parking service server. The parking sensor module 20 is configured. The illustrated parking lot 10 is composed of a plurality of management target parking surfaces 11 configured with the parking sensor module 20, and each parking sensor module 20 detects vehicles parked in the corresponding parking lot 10. Based on the parking and departure information, the remote parking service server calculates the parking cost for each vehicle.

If such a parking lot 10 exists in a certain range and the entry/exit area is limited, the parking service server may calculate the parking cost in conjunction with a video analysis system including a separate camera, but usually video analysis including a camera In the case of the system, there is a problem of relatively high installation and operation costs.

In addition, in the case of a public parking lot installed along the road or a parking lot installed in a space where entry and exit is free, not only the number of required cameras increases, but also the installation and operation costs due to the space for installing cameras and facilities for power supply increase. Research is being conducted to accurately check whether the vehicle is parked or not using only the parking sensor module.

Figures 2 and 3 show the configuration of the parking sensor module 20 used in the embodiment of the present invention, Figure 2 shows the appearance and Figure 3 shows the internal configuration.

4 shows the configuration of a parking management system for managing the parking lot 10 using the parking sensor module 20 according to an embodiment of the present invention.

As shown, the parking sensor module 20 includes a case composed of a lid portion 21 and a body portion 22, and the lid portion 21 and the body portion 22 are separated through a separate sealing means. completely sealed

One or more of these parking sensor modules 20 may be installed in a designated area of the parking surface 11, and are configured to enable continuous operation for several years even if installed in a buried manner.

The parking sensor module 20 according to the illustrated embodiment includes a battery unit 23 that guarantees use for several years or more and a measurement unit 24 configured with a plurality of sensors and communication units therein.

Such a measurement unit 24 is composed of one or more vehicle detection sensors, for example, a geomagnetic sensor, a loop sensor, a laser sensor, an optical sensor, an ultrasonic sensor, a radar sensor, a lidar sensor, a camera sensor, an acoustic sensor, and the like may be applied. .

The measuring unit 24 according to an embodiment of the present invention may be a combination of a geomagnetic sensor and a laser sensor, and the geomagnetic sensor may be a multi-axis geomagnetic sensor capable of measuring multi-axis geomagnetism.

On the other hand, the measuring unit 24 according to this embodiment can accurately grasp the parking and departure conditions of the vehicle 30 by operating the geomagnetic sensor and the laser sensor sequentially or simultaneously, and by external environmental factors, a plurality of Even if one of the sensors malfunctions, it is possible to detect the existence of a vehicle or the state of parking or leaving, thereby increasing measurement reliability, thereby accurately determining whether a vehicle is parked or departing without separate image analysis.

Due to the characteristics of the parking sensor module 20, which normally operates based on the battery 23, power consumption must be minimized, so each sensor of the measuring unit 24 periodically repeats sleep and wake-up to check the presence of a vehicle. Alternatively, when a specific sensor operates in a watchdog state and a change in the presence or absence of a vehicle is expected, measurement may be performed by operating other sensors, and the communication unit may also operate only in a selective situation according to the parking state or cycle of the vehicle.

On the other hand, the use period can be extended by adding an energy harvesting means (for example, a piezoelectric power generating means, a wireless power receiving means, a temperature difference generating means, a solar power generating means, etc.) or a wireless power charging means to the parking sensor module 20. can

In the embodiment of the present invention, a communication unit capable of communicating with the remote parking service server 60 using LoRa may be configured in the measurement unit 24 .

On the other hand, when the vehicle 30 is parked on the parking surface 11, a short-range communication unit may be further configured in the measurement unit 24 to provide information about the parking surface 11 to the driver of the vehicle, which is also Wireless LAN (WLAN), DLNA (Digital Living Network Alliance), Wireless Broadband (Wibro), WiMAX (World Interoperability for Microwave Access: Wimax), GSM (Global System for Mobile communication), CDMA (Code Division Multi Access), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), WCDMA (Wideband CDMA), HSDPA (High Speed Downlink Packet Access), HSUPA (High Speed Uplink Packet Access) Access), IEEE 802.16, Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), Wireless Mobile Broadband Service (WMBS), 5G mobile communication service, Bluetooth ), LoRa (Long Range), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, Near Field Communication (NFC), Ultrasonic Communication ( It may be a communication unit for supporting one of Ultra Sound Communication (USC), Visible Light Communication (VLC), Wi-Fi, and Wi-Fi Direct.

In the illustrated embodiment, the measuring unit 24 can provide information on the parking surface 11 of the vehicle 30 to the driver terminal 35 in the vehicle using a Bluetooth (specifically, BLE: Bluetooth Low Energy) communication method. can be configured so that

The in-vehicle driver terminal 35 has a dedicated application installed to receive parking surface 11 information provided by the measurement unit 24 in a Bluetooth communication method, and provides it to the parking service server 60 along with its own terminal identification information. .

The driver terminal includes a smart phone, a portable terminal, a mobile terminal, a personal digital assistant (PDA), a portable multimedia player (PMP) terminal, a telematics terminal, Navigation terminal, personal computer, notebook computer, slate PC, tablet PC, ultrabook, wearable device (for example, a watch type terminal ( Smartwatch), glass-type terminal (Smart Glass), HMD (Head Mounted Display), etc.), Wibro terminal, IPTV (Internet Protocol Television) terminal, smart TV, digital broadcasting terminal, television, 3D television, It may be various terminals such as a home theater system, an audio video navigation (AVN) terminal, an audio/video (A/V) system, and a flexible terminal.

Such a driver terminal 35 and the parking service server 60 are wireless LAN (WLAN), DLNA (Digital Living Network Alliance), WiBro (Wireless Broadband: Wibro), WiMAX (World Interoperability for Microwave Access: Wimax) , GSM (Global System for Mobile communication), CDMA (Code Division Multi Access), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), WCDMA (Wideband CDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), IEEE 802.16, Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), broadband wireless mobile communication service (Wireless Mobile Broadband Service: WMBS), 5G mobile communication service, Bluetooth, LoRa (Long Range), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee , Near Field Communication (NFC), Ultra Sound Communication (USC), Visible Light Communication (VLC), Wi-Fi, Wi-Fi Direct can communicate as one.

The parking service server 60 may include a device communication unit for communicating with a plurality of different external devices through a communication network, a device storage unit for storing various information, and a control unit, and may be configured as a server having such a configuration. . For example, it may be composed of one server, a plurality of servers, or a cloud-type server, and may also be composed of one of various terminals such as the driver terminal exemplified above.

Through this configuration, the parking service server 60 can check whether the vehicle 30 is parked or kicked out through the parking sensor module 20 installed on the parking surface 11, and the parking sensor module 20 provides Parking surface information and terminal identification information (driver information) are received from the driver terminal 35 that has received the parking surface information, and the parking cost for the vehicle 30 parked on the corresponding parking surface 11 is calculated, and the parking start and At the end time, a guide message according to the start and end of parking may be provided to the driver terminal 35 . Furthermore, parking costs may be automatically settled based on the driver terminal identification information.

Through this parking service system, unmanned parking management for the vehicle is possible, and the user can process the cost of the parking lot through the driver's terminal carried without calling a manager or using a separate calculator, and automatically processing it. When set, driver convenience increases as there is no need to worry about parking.

However, since the illustrated parking sensor module 20 operates a plurality of sensors to directly determine whether the vehicle is detected and transmits the determination result to the parking service server 60, it is difficult to verify its reliability. In particular, some of the sensors may not operate normally for a certain period of time depending on the weather, the geomagnetic distribution of the installation area, the existence of heavy conductors in the adjacent area, and environmental influences such as rain, fog, moisture, dew, and dust. Each parking sensor module determines whether some sensors are malfunctioning due to environmental influences according to its own algorithm and uses the measured values of all sensors for vehicle detection or excludes the measured values of some sensors from vehicle detection. In the case of a parking sensor module in which it is difficult to directly check an enemy change, the reliability for classifying such a malfunctioning sensor is low.

In particular, the parking sensor module uses a sensor reference value for compensating the measurement value of each sensor according to the installation environment or determining vehicle detection. (For example, by accumulating 5 measured values at the time of the latest successful vehicle presence change determination, each for when the vehicle is present and when there is no vehicle, and using the average as the sensor reference value), a deflected or distorted sensor reference value is set for follow-up. There may also be cases where it has a lasting effect on the measurement.

In particular, there is a limit in that the reliability of vehicle detection is not high because the effectiveness of such sensing, classification of malfunctioning sensors, and updating of sensor reference values are simplified to minimize power consumption.

5 to 7 show a conceptual diagram of a parking service system according to an embodiment of the present invention, a configuration diagram of a parking sensor module 100 applied to the parking service system, and a configuration diagram of a parking service server 200.

The parking service system shown in FIG. 5 includes the basic parking sensor module 100 described above in FIG. 4 for sensing for detecting a vehicle and a configuration for transmitting parking surface information to a driver terminal, and the parking service server 100 also A configuration for parking cost settlement through parking surface information and driver terminal identification information through the driver terminal is included as it is.

However, in the embodiment of the present invention, the configuration and operation of the parking sensor module 100 for vehicle detection and the configuration and operation of the parking service server 200 are improved as follows.

First, as shown in FIG. 5, the parking service system according to an embodiment of the present invention receives sensor measurement values from the parking sensor module 100 and the corresponding parking sensor module 100 respectively configured on the parking surface of the parking lot 110. A parking service server 200 is included.

Instead of the parking sensor module 100, which cannot reflect limited computational efficiency and environmental changes, independently determining the existence of a vehicle, in the embodiment of the present invention, the measured value determined by the parking sensor module 100 as valid is used as a parking service. When transmitted to the server 200, the corresponding parking service server 200 determines whether a vehicle exists. In this way, when the parking service server 200 determines the existence of a vehicle or its change, weather information or regional information about the malfunctioning environment of the sensor can be collected as environment information, so that the sensor that malfunctions by reflecting the environment information When determining the presence of a vehicle based on the measured value, an analysis algorithm with a high computational load or a deep learning neural network model (various types of artificial intelligence classification, prediction algorithms) can be applied. A change in the existence of a vehicle can be determined with high reliability.

Meanwhile, in order to determine whether or not the measured value is valid, each parking sensor module 100 has a sensor reference value for each configured sensor and continuously updates it. Such a sensor reference value is, for example, when vehicle detection (vehicle parking, vehicle departure) is successfully performed, the effective sensor value used in the measurement is added to the sensor reference value list (vehicle presence and non-existence, respectively) for the corresponding sensor, and the latest An average of n valid sensor values may be used as a sensor reference value. Of course, the sensor reference value may be set in a different way, but in order to intelligently reflect the environmental influence, each parking sensor module updates the reference value of an individual sensor based on its measurement value.

However, since each parking sensor module 100 independently updates the sensor reference value based on its own measured value, the measured value belongs to the effective range but has a slightly larger deviation than the previous measured value (noise mixed or sensor The reference value may be excessively biased or distorted when the measured values including errors according to the characteristics of ) are accumulated.

Therefore, in the embodiment of the present invention, the parking service server 200, which has received the valid measurement value provided by the parking sensor module 100, corresponds to the received valid measurement value when a change in the presence or absence of a vehicle is confirmed, to the corresponding parking sensor module. However, if there is a large deviation from the previously recorded effective measured value, the measured value is corrected by reflecting the average of the latest measured value of the adjacent (preset group, certain radius, same parking lot, etc.) parking sensor module instead of recording the measured value as it is. After that, it is recorded, and the corrected information is transmitted to the parking sensor module 100 as a sensor reference value for updating and used to update the sensor reference value.

Through this, it is possible to check parking and departure of a more stable and reliable vehicle.

Furthermore, in the case of such a parking sensor module 100, power management is required because it must operate for several years using a built-in battery, and for this purpose, the parking sensor module 100 according to an embodiment of the present invention management to reduce power consumption.

6 is a configuration of the parking sensor module 100 configured in FIG. 5, and FIG. 7 is a configuration of the parking service server 200 configured in FIG.

First, the parking sensor module 100 shown in FIG. 6 includes a monitoring mode that generates a wake-up signal when a change in geomagnetism is detected based on a preset base sensing value, and a sensing mode that detects a change in the presence or absence of a vehicle as a change in geomagnetism. A geomagnetic sensor unit (first sensor unit) 100 operating as one and a laser sensor operating in a sensing mode that generates a measurement value for detecting the presence of a vehicle in a method different from that of the geomagnetic sensor unit 110, which is the first sensor unit. unit (second sensor unit) 120, a communication unit 130 communicating with the remote parking service server 200, and a reference value setting unit accumulating and updating sensor reference values for each sensor to determine the validity of the sensing values of each sensor unit ( 150), a monitoring management unit 160 that operates the geomagnetic sensor unit (first sensor unit) 110 in monitoring mode and periodically provides a wake-up signal for monitoring all sensors, and each component (laser sensor unit) 120, the communication unit 130, the reference value setting unit 150, the control unit 140, etc.) and the power management unit 170 that selectively provides power, and the geomagnetic sensor unit (first sensor unit) 110 or monitoring All of the sensor units 110 and 120 are operated in the sensing mode according to the wake-up signal from the management unit 160, and the measured values of each sensor unit 110 and 120 are compared with the sensor reference value for each sensor of the reference value setting unit 150. When there is a measured value determined to be valid, the communication unit 130 is operated through the power management unit 170 to transmit the valid measured value to the parking service server 200, and if there is no valid measured value, sleep mode conversion is controlled. It includes a control unit 140.

The second sensor unit may be a loop sensor, a laser sensor, an optical sensor, an ultrasonic sensor, a radar sensor, a lidar sensor, a camera sensor, an acoustic sensor, etc. ) is described as an example.

The illustrated geomagnetic sensor unit 110 can operate in a monitoring mode that operates based on a wake-up sensing value separate from vehicle detection. Through a passive configuration that compares only the output change of the multi-axis geomagnetic sensor with the wakeup sensing value, when an output change exceeding the corresponding wakeup sensing value occurs, a wakeup signal is generated to wake up the control unit 140 in sleep mode. .

The monitoring and management unit 160 may also wake up the control unit 140 in the sleep mode by generating a wake-up signal at a preset point in time using a watchdog timer.

The monitoring mode of the geomagnetic sensor unit 110 and the watchdog timer of the monitoring management unit 160 consume very little power, and the rest of the components consume little power until a wake-up signal is provided. state, so the limited battery power can be used efficiently.

The control unit 140 that receives the wake-up signal from the geomagnetic sensor unit 110 or the monitoring management unit 160 wakes up from the sleep mode according to the wake-up signal and independently operates all of the configured sensor units 110 and 120 to measure the After the values are collected, they are compared with the reference values for each sensor. Based on the value set as the reference value for each sensor (vehicle presence, vehicle absence), measured values within a certain range are judged as valid measured values, and The measured value is judged as an invalid measured value and ignored. For example, if the measured value according to the presence of a vehicle is 100 and the reference value of the corresponding sensor according to the presence of the vehicle is 95, the measured value 100 is valid if 20 below and above the reference value is set as an effective range. If the measured value is 70 or 120, it can be determined to be invalid.

The control unit 140 transmits the valid measurement value to the parking service server 200 (the contents of the transmission of the valid measurement value include identification information of the parking sensor module, information on the valid measurement value and the type of sensor that measured it), When the vehicle detection result is received from the parking service server 200, a valid measurement value is provided to the reference value setting unit 150 according to whether the vehicle exists or not, so that the sensor reference value for the sensor that measured the effective measurement value is updated or without updating the sensor reference value. Control sleep mode transition.

That is, when the parking service server 200 determines that the state of the vehicle maintains the existing state, the parking sensor module 100 further confirms the existing state, so it is switched back to the sleep mode without any change and the monitoring mode operates. , When it is determined that there is no vehicle state (parking) or there is no vehicle state (departure), the parking sensor module 100 updates the reference value for each sensor of the reference value setting unit 150 and then switches to the sleep mode. will do Here, the update of the reference value for each sensor is a method of accumulating n effective measurement values when there was a previous change in vehicle presence and then using the average as the reference value of the sensor, deleting the oldest among the existing n accumulated measurement values and updating the latest Sensor measurements can be updated by adding valid measurements.

On the other hand, although the parking service server 200 determines the change in whether or not there is a vehicle through the valid measured value transmitted by the parking sensor module 100, the valid measured value is the same as the previously stored valid measured value for the same parking sensor module and the criterion. If the above deviation is shown, the received effective measurement value can be corrected (simply replaced) using the average of the latest valid measurement values of adjacent parking sensor modules, or a weighted value can be applied to the effective measurement value to be close to the average. The difference between effective measured values may be reduced to a certain level), and the corrected measured values are used as sensor reference value information for updating (information on the type of sensor corresponding to the corrected measured values), and the parking sensor module 100 can be forwarded to

When the control unit 140 receives the update sensor reference value information while receiving the vehicle detection result from the parking service server 200, the controller 140 provides the sensor reference value information for update to the reference value setting unit 150 to provide the sensor for the corresponding sensor. After updating the reference value, switching to sleep mode can be controlled.

On the other hand, the control unit 140 cuts off the power of the components 120, 130, and 150 other than the preset components 110 and 160 for monitoring mode operation through the power management unit 170 to switch to the sleep mode, and You can switch to a low power sleep mode.

Through this, the parking sensor module 100 of the present invention utilizes the geomagnetic sensor operating in a passive manner as a vehicle detection and separate wake-up detector to reduce power consumption, and applies periodic wake-up using a timer in parallel to malfunction of the geomagnetic sensor. It is possible to effectively detect vehicles even in the environment, thereby reducing battery power consumption and increasing measurement reliability.

In addition, it is possible to increase the reliability of determining the effective value of the parking sensor module by managing the sensor reference value for each parking sensor module so that it is not excessively biased or distorted, and the parking service server 200 instead of the control unit 140 with limited computational load determines whether a vehicle exists or not. Since the change is determined, the reliability of vehicle detection can be increased and the computational load of the parking sensor module 100 can be reduced. In particular, the recent communication unit 130 is configured to enable long-distance communication with low power, and LoRa designed to reduce power consumption of battery-based IoT devices exists, and since further improved communication methods will be provided in the future, the parking sensor module ( 100), long-distance communication may be possible with the degree of power consumption according to the operation.

When the latest information of the management unit 250 and the specific parking sensor module 100 stored in the reference value management unit 250 has a deviation greater than or equal to the reference value compared to previously stored sensor measurement values, adjacent parking sensor modules stored in the reference value management unit 250 The latest information of the specific parking sensor module 100 is corrected and stored using the latest information of (100), and the corrected information is used as sensor reference value information for updating through the sensor module communication unit 210. The specific sensor module 100 It includes a reference value updating unit 260 to transmit to.

The reference value updating unit 260 updates the latest information of the specific parking sensor module 100 to be stored in the reference value management unit 250 (when a vehicle exists according to a change in whether or not a vehicle exists, the measurement value of sensors according to 'parking', the presence of a vehicle If the measured value of sensors according to 'departure/absence' has a deviation greater than the standard, the average value of the latest information (latest measured value for each situation of parking and departure) of adjacent parking sensor modules stored in the standard value management unit is used to determine the specific value. The latest information of the parking sensor module is corrected to be close to the average value.

Here, the range of the adjacent parking sensor module is limited to a parking sensor module directly in contact with the specific parking sensor module 100 (a parking sensor module that exists among left, right, top and bottom), or parking where the specific parking sensor module 100 is disposed. It may be limited to parking sensor modules disposed in a surface area (set area such as area A or area B) or a corresponding parking lot.

On the other hand, the vehicle determination unit 230 determines the measured value of each sensor of the parking sensor module 100 and the measured value of a plurality of sensors received through a deep learning neural network model (algorithm) that has learned the result of changing the presence or absence of a vehicle. A vehicle presence/absence change state may be determined. That is, the presence of a vehicle can be more accurately determined by applying various statistical and analytical methods that require a large computational load.

Furthermore, as shown, the parking service server 200 includes a driver terminal communication unit 230 that receives parking surface information and terminal identification information transmitted by a driver terminal that has received parking surface information provided by the parking sensor module 100 and , According to the determination result of the vehicle determining unit 220, the parking management unit 240 may include a parking management unit 240 that separates the start and end of parking for the parking surface on which the parking sensor module 100 is installed and performs settlement.

As shown, a monitoring step of generating a wake-up signal when the parking sensor module detects a change in the geomagnetic field according to the approach of a vehicle or an object based on a vehicle detection and a separate base sensing value or when a predetermined time is reached.

If a wake-up signal is generated in the monitoring step, the parking sensor module independently operates a plurality of sensors to generate a sensing value, and determines an effective measurement value by comparing it with a preset reference value for each sensor. includes

Here, the validity of the measured value may be determined by whether the measured value for each sensor falls within a set range of the reference value for each situation (vehicle presence, vehicle absence) of the reference value for each sensor.

Thereafter, a transmission step in which the parking sensor module transmits the measurement value for each sensor determined as a valid measurement value to the parking service server, and the parking service server uses the measurement value for each sensor received from the specific parking sensor module to detect changes in the existence of the vehicle. It includes a decision step of making a decision.

In the determining step, when it is determined that the presence or absence of a vehicle has changed, the parking service server stores the received measurement value in correspondence with the corresponding parking sensor module, but if the deviation from the previously stored measurement value is greater than or equal to the standard, the parking sensor module is disposed adjacent to the corresponding parking sensor module. A correction step of correcting the stored measurement value using the average of the last stored measurement value of other parking sensor modules and storing it instead.

Thereafter, a result transmission step in which the parking service server transmits the result of determining the change in the presence or absence of a vehicle in the determining step to the parking sensor module as a vehicle detection result, and the monitoring after the parking sensor module receiving the vehicle detection result switches to the sleep mode. Includes a completion step that executes the step.

Meanwhile, the result transmission step further transmits the measured value corrected in the correction step to the parking sensor module as update reference value information, and the completion step uses the update reference value information received by the parking sensor module receiving the update reference value information from the parking service server. After updating the reference value for each sensor, it is possible to switch to the sleep mode.

In this way, the weight is sensed in a low-power state using the self-determined sensor and the timer configured in the parking sensor module as a wake-up generating means, and after wake-up, a plurality of sensors are independently operated to calculate the measured value Then, if the measured value is greater than or equal to the reference value for each sensor, it is transmitted to the parking service server. The parking service server determines the change in vehicle presence (parking or departure) based on the valid measured values, but uses environmental information more or uses a deep learning model. It is possible to more reliably determine the presence of a vehicle through an advanced determination method such as applying .

Furthermore, after the parking service server detects a change in the presence of a vehicle through the effective measurement value provided by the parking sensor module, when the existence of the vehicle has changed, the corresponding effective measurement value is accumulated and stored in correspondence with the parking sensor module, and the previously stored valid measurement value and If the deviation of is greater than the standard, the stored measurement value is corrected using the average of the last stored measurement values of other parking sensor modules disposed adjacent to the corresponding parking sensor module and stored instead, and the corrected measurement value is used as the reference value for updating. Parking By providing it to the sensor module, it is possible to increase measurement reliability by preventing the sensor reference value for each parking sensor module from being excessively deflected or distorted.

In addition, by using the geomagnetic sensor as a vehicle detection and separate wake-up detector to reduce power consumption, and by applying periodic wake-up using a timer in parallel, the vehicle can be effectively detected even in a malfunctioning environment of the geomagnetic sensor, thereby reducing battery power consumption. At the same time, measurement reliability can be improved.
