Parking sensor module inspection device, parking sensor module inspection system, and inspection thereof that increase maintenance efficiency by easily identifying errors in multiple sensors and multiple communication units by inspecting modules in a standardized way using portable equipment and correcting setting errors It relates to a method and a non-volatile recording medium on which a computer program for checking the method is recorded.

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 is added to the recent parking sensor module, and a terminal carried by a driver wirelessly receives the corresponding parking surface information and transmits identification information of the parking surface and terminal to the parking service server. this 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.

In this parking sensor module, various types of different sensors are configured to increase measurement accuracy, various types of communication units are configured, and the possibility of failure or error occurrence is high because it is exposed to the outdoors and used for a long period of time. In addition, each of the various sensors for detecting a vehicle has a sensor reference value for determining whether or not a vehicle exists. Since such a sensor reference value is individually updated according to the installation location and environment of each parking sensor module, the parking service server can remotely It is not easy to check and verify the normal operation of the parking sensor module. Furthermore, when an error occurs, there is a problem in that a lot of time and cost are incurred in maintenance such as opening a parking sensor module attached to a parking surface in a completely sealed manner to check an error, thereby reducing economic feasibility.

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.

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

The measurement unit 24 includes a communication unit that wirelessly communicates with the parking service server 60 and provides vehicle detection information. This communication unit includes 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), IEEE 802.16, Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), Wireless Mobile Broadband Service (WMBS), 5G mobile communication service, Bluetooth, LoRa (Long Range), RFID (Radio Frequency Identification), infrared communication (Infrared Data Association: IrDA), UWB (Ultra Wideband), ZigBee, Near Field Communication (NFC), Ultra Sound Communication (USC), Visible Light Communication (VLC), It may be a communication unit for supporting Wi-Fi, Wi-Fi Direct, and the like.

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.

In addition, since the parking sensor module 20 must maintain a completely sealed state and is attached to the parking surface, it is difficult to check whether or not the parking sensor module 20 is abnormal from the outside. Therefore, the parking sensor module 20 according to the embodiment of the present invention may be equipped with a function for inspecting the corresponding parking sensor module 20 from the outside.

As shown in FIG. 3, a non-contact communication unit 25 may be configured in the parking sensor module 20. This non-contact communication unit 25 is inspected through non-contact means such as light, magnetic force, sound waves, and wireless signals. A start signal may be received, and the measuring unit 24 receiving the signal may perform a preset inspection procedure by switching an operation mode to an inspection mode.

Such a non-contact communication unit 25 may include various wireless communication methods described above, but a lead that responds to a strong magnetic force directly applied in order to receive an actual physical and direct inspection signal separately from other types of wireless noise signals Extremely simple and low-fault means such as switches can also be used. Of course, the corresponding inspection start signal may include a certain pattern or information so as not to misidentify the inspection start signal only with simple magnetic force, but may simply be a digital signal pattern of a promised speed.

When the measurement unit 24 is switched to the inspection mode, it performs test communication with a plurality of communication units (communication units for communicating with the remote parking service server, communication units for communication with the driver's terminal, etc.) It is possible to measure sensors and determine a vehicle accordingly, and provide measurement results of each sensor and a vehicle determination result. The provision of the corresponding result may be transmitted to a local area through a plurality of communication units or delivered to a parking service server in a remote location.

Meanwhile, as shown in FIG. 1 , a plurality of parking sensor modules 20 exist in a certain area, but each has a sensor reference value for independently correcting the sensing values of the sensors or determining the presence of a vehicle. The sensor reference value is initially constant, but due to the characteristics of the sensors for detecting the vehicle (for example, by using means such as geomagnetism whose characteristics change according to time and season, light and sound waves whose characteristics change according to the external environment), it is adjusted according to the external environment. The sensor reference value is changed autonomously.

For example, the measurement unit 24 of the parking sensor module 20 that determines the parking and departure of the vehicle accumulates the last certain number among the successfully determined sensing values and uses the average as a sensor reference value, The sensor reference value is also used to determine whether the measured value is noise or a significant value, and the sensor reference value is adjusted if the frequency of determining the measured value as noise or a significant value is excessive.

As a result, the plurality of parking sensor modules 20 disposed in a certain area have different sensor reference values over time. may occur

However, since it is difficult for the parking service server 60 to remotely receive only the information provided by the parking sensor module 20 in practice, it is difficult to verify whether each parking sensor module 20 accurately determines the presence or absence of a vehicle. It is difficult to distinguish the parking sensor module 20 in which an error has occurred.

Furthermore, in the case of the parking sensor module 20, even if it is located in a similar location due to environmental factors, there may be deviations in the sensor reference value, so even if the parking service server receives and confirms the sensor reference value, the actual manager uses the vehicle to detect the parking sensor. Before checking the operation of the module 20, there is a problem that it is difficult to check whether there is an error.

In addition, when the parking sensor module 20 is embedded in the parking surface and completely sealed with a plurality of sealing means, it is difficult to accurately determine whether parts need to be replaced or settings can be changed for errors in some functions, and individual parking Since standardized inspection of the sensor module 20 is also difficult, in the case of a parking sensor module 20 in which an error occurs, the entire vehicle is replaced over a certain period of time, resulting in increased maintenance costs.

Therefore, the present invention proposes a new method of checking whether the parking sensor module 20 is abnormal using a standardized method, checking an error according to the deviation of the sensor reference value, and updating it.

5 shows a configuration example of a parking sensor module inspection device 100 according to an embodiment of the present invention, FIG. 5A is a side view, and FIG. 5B is a top view.

As shown, the parking sensor module inspection device 100 is configured with a frame 101 of a portable size and a predetermined position of the frame 101 so that each sensor configured in the parking sensor module to be inspected can determine that the vehicle is parked. The reference panel 120 prepared in a material, size, and shape of a certain degree, and the frame 101 or the reference panel 120 so as to be in a position adjacent to the parking sensor module to be inspected during the inspection, provide non-contact information indicating the start of the inspection. Test communication is performed with the non-contact communication unit 110 provided in the method and each communication unit configured in the frame 101 and configured in the parking sensor module to be inspected, and the results are collected, and the measurement of each of the sensors for the reference panel is performed. Includes an inspection terminal 130 that collects test results and vehicle determination results and provides inspection results, and a handle portion 102 that is connected to the frame 101 to support the inspection terminal 130 and performs a handle function for carrying. do.

Furthermore, an extension part 104 for connecting the non-contact communication unit 110 to the frame 101 may be further configured, or a joint part 103 capable of folding the reference panel 120 into the frame 101 may be further included. there is.

In the parking sensor module inspection device 100 as described above, the reference panel 120 may be folded toward the frame 101 during movement, and the inspection may proceed after unfolding the reference panel 120 during inspection.

The corresponding reference panel 120 is configured so that the parking sensor module can be recognized as an actual vehicle when deployed in a position installed on the frame 101, for example, a metal or a magnetic material (eg ferrite material mixture) to correspond to a geomagnetic sensor. etc., may have appropriate reflectivity to correspond to a laser sensor or optical sensor, and may have an appropriate reflection or shielding function to correspond to a sound wave sensor. By standardizing the reference panel 120, it is possible to clearly determine the measurement accuracy of each sensor or the vehicle determination reliability.

In an embodiment of the present invention, the reference panel 120 may be made of a conductor or a magnetic material having a size and surface that can be reliably recognized as a vehicle by a geomagnetic sensor and a laser sensor.

In addition, the non-contact communication unit 110 is configured to transmit a signal for inspection start through a non-contact method such as light, magnetic force, sound wave, or wireless signal. Basically, it only needs to be able to transmit a signal for the start of inspection, but if necessary, a two-way communication method capable of exchanging information on inspection with the parking sensor module can be supported.

Such a contactless communication unit 110 is 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), Code Division Multi Access (CDMA), Code Division Multi Access 2000 (CDMA2000), Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-DO), Wideband CDMA (WCDMA), 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), 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 Communication: It can support wireless communication such as NFC), Ultra Sound Communication (USC), Visible Light Communication (VLC), Wi-Fi, and Wi-Fi Direct. . However, in order to simplify the configuration, after configuring a magnetic force sensing means such as a reed switch or a Hall sensor in the parking sensor module, the illustrated non-contact communication unit 110 may be configured to provide a magnetic force signal having a predetermined pattern through an electromagnet. .

By displaying, it is possible to provide the manager with information on whether or not there is an error and the subject or degree of the error in case of an error, and the information can be delivered to the parking service server.

Furthermore, if the occurrence of an error is a sensor reference value deviation problem of sensors provided in the parking sensor module, it is updated and then checked again to confirm whether the error is due to the sensor reference value deviation.

Hereinafter, the operation of the inspection system using the parking sensor module inspection device according to an embodiment of the present invention will be described with reference to FIGS. 6 and 7 .

6 is a system configuration diagram for explaining the operation of the present invention.

As shown, the parking sensor module inspection system includes a parking sensor module 20, a parking sensor module inspection device 100, a communication network 50, and a parking service server 60.

First, the parking sensor module 20 according to an embodiment of the present invention is tested through a plurality of vehicle detection sensors, a plurality of communication units, a non-contact communication unit receiving a test start signal in a non-contact communication method, and the communication units according to the test start signal. Communication is performed and the measurement results and vehicle determination results through the detection sensors are transmitted to the parking sensor module inspection device 100 or the parking service server 60.

On the other hand, the corresponding parking sensor module 20 updates the sensor reference value by itself by accumulating a plurality of the latest measurement results of each sensor according to the measured values of the provided sensors or the vehicle determination result, and updates the updated sensor reference value to the parking service server ( 60) can be transmitted.

If the parking sensor module 20 can directly exchange information with the parking sensor module inspection device 100 in a short-range communication method, the parking sensor module 20 communicates directly with the parking sensor module inspection device 100 during the inspection process. Inspection can be done in this way.

However, if there is no communication means for directly exchanging information about inspection with the parking sensor module inspection device 100 in the parking sensor module 20, the parking sensor module 20 and remote information may be exchanged. The parking sensor module inspection device 100 may indirectly receive information according to the inspection process of the inspection target parking sensor module 20 through the parking service server 60 that can be transmitted and received.

The parking sensor module inspection device 100 provides a reference panel 120 prepared in a material, size, and shape to the extent that each sensor configured in the parking sensor module 20 to be inspected determines that the vehicle is parked, and a test start signal Test communication is performed with the non-contact communication unit 110 for the test and each communication unit configured in the parking sensor module to be inspected to collect the result, and the test result is collected by collecting the measurement result of each sensor and the vehicle determination result for the reference panel 120. It includes a test terminal 130 that provides.

Here, the inspection terminal 130 transmits inspection start information of a preset pattern to the inspection target parking sensor module 20 through the non-contact communication unit 110, and the inspection starts from one of the communication units configured in the corresponding parking sensor module 20. After confirming the response to the information received, proceed with the inspection. The corresponding response may be received directly or indirectly through the parking service server 60 .

Upon the start of the inspection, the inspection terminal 130 receives test communication information provided by the communication unit configured in the parking sensor module 20 to be inspected, performs a preset communication procedure with the corresponding communication unit, or A test communication result of the parking sensor module to be inspected is received from the parking service server 60 that remotely manages.

If an error occurs in the communication process, even if the vehicle is normally determined, parking surface information cannot be provided to the driver or vehicle parking information cannot be provided to the parking service server 60, so it can be determined as the most serious error, In the case of a substantial communication unit error, the inspection may be terminated at that stage. However, the possibility of an error in the communication unit occurring in the parking sensor module 20 having a substantially completely enclosed structure is not high.

If there is no error in the communication units of the parking sensor module 20 to be inspected during the communication inspection process, errors in each sensor provided in the parking sensor module 20 to be inspected are checked.

The parking sensor module inspection device 100 may receive measurement results and vehicle determination results for each sensor of the parking sensor module 20 to be inspected with respect to the reference panel 120 and check malfunction through the results.

Such a malfunction is judged as a sensor error when the measured values of the sensors fall within the preset failure range (normally, the measured value at a level that is difficult to be measured by the corresponding sensor, the measurement change (vibration) range that is impossible during continuous measurement, etc.) Thus, the failure can be displayed to the manager as inspection result information or transmitted to the parking service server 60 .

However, as described above, since the parking sensor module 20 updates the sensor reference value by itself by accumulating a plurality of the latest measurement results of each sensor according to the vehicle determination result, the independently updated sensor reference value is biased or distorted. It may also occur frequently that the presence of is not accurately determined.

Therefore, in the parking sensor module inspection apparatus 100 according to an embodiment of the present invention, measurement results and vehicle determination results for each sensor of the parking sensor module 20 to be inspected targeting the reference panel 120 in the inspection process. is received and an error occurs outside the failure range, the parking sensor module 20 to be inspected is requested to update the reference value for each sensor, and after updating the sensor reference value, the sensor measurement and vehicle determination results are checked again.

In particular, the parking sensor module inspection device 100 transmits the sensor reference value of the inspection target parking sensor module 20 to the parking service server 60 that remotely manages the inspection target parking sensor module 20. It is requested to update the average sensor reference value of the arranged area (parking lot), or the average sensor reference value is received from the parking service server 60 and provided to the inspection target parking sensor module 20 as sensor reference value update information.

The parking service server 60 communicates with the parking sensor module 20 to receive measurement results of each sensor or vehicle determination result and sensor reference value from the parking sensor module 20, and the parking sensor module 20 to be inspected is disposed. The average reference value of the area (parking lot) can be calculated. That is, although the sensor reference values may differ from each other depending on the location characteristics of each parking sensor module 20, since the deviation between parking sensor modules 20 disposed in the same area is not excessively large, the average sensor reference value is used. When the sensor reference value of the specific parking sensor module 20 that is biased or distorted is updated, the possibility of correcting the malfunction increases.

Meanwhile, when the parking sensor module inspection device 100 cannot directly communicate with the inspection target parking sensor module 20, the parking sensor module inspection device 100 requests the parking service server 60 to update the sensor reference value, When information indicating that the sensor reference value of the parking sensor module 20 has been updated is received from the parking service server 60, the measurement result of each sensor of the parking sensor module 20 and the vehicle determination result are checked again to malfunction. Check if this happens again. In the case of the parking sensor module 20, when a sensor reference value update is requested and the existing sensor reference value is updated with the received reference value, the sensor measurement result for the reference panel 120 and the vehicle detection result are obtained again based on the sensor reference value and then transmitted. .

7 is a configuration block diagram of a parking sensor module inspection device 100 according to an embodiment of the present invention.

As shown, it is composed of a reference panel 120, a non-contact communication unit 110, and an inspection terminal 130. The inspection terminal 130 controls the non-contact communication unit 110 to start inspection on the parking sensor module 20 to be inspected. The inspection synchronizing unit 132 that provides information notifying the inspection, the communication test unit 134 that performs test communication with the communication unit configured in the parking sensor module 20 to be inspected and collects the result, and the reference panel 120. The sensor test unit 135 that collects the measurement results and vehicle determination results measured by each sensor of the parking sensor module 20 to be inspected and the sensor reference value of the parking sensor module 20 to be inspected are received and the It controls the inspection process of the setting test unit 136 that is changed and updated, the inspection synchronization unit 132, the communication test unit 134, and the sensor test unit 135, and the measurement results of the sensor test unit 135 or If there is an error in the vehicle determination result, the sensor reference value of the parking sensor module 20 to be inspected is updated through the setting test unit 136, and then the measurement result and the vehicle determination result are reconfirmed through the sensor test unit 135. Under the control of the execution unit 137 and the inspection execution unit 137, the inspection progress status and inspection result are visually or audibly displayed to the manager, and inputs such as inspection start or sensor reference value renewal request and result transmission are received by the manager. It may include an interface unit 131 to.

If the inspection terminal 130 cannot directly communicate with the inspection target parking sensor module 20 or needs to share the inspection result with the parking service server 60, the inspection terminal 130 is the inspection target parking sensor module ( 20) may further include a server interlocking unit 133 that communicates with the parking service server 60 that remotely manages, collects information on the parking sensor module 20, or requests a setting change for the parking sensor module 20. can

Through this, while carrying the parking sensor module inspection device 100, it is possible to carry out a standard, quick, and accurate inspection of the parking sensor modules 20 disposed in a number in a certain area.

For example, when trying to inspect the parking sensor module 20 disposed on the parking surface 11 of the parking lot shown in FIG. 8, the inspection of the parking sensor module 20 of each parking surface can be performed sequentially and quickly, Even if there is an error in sensor measurement or vehicle determination of a specific parking sensor module 20a, normal operation after updating the sensor reference value of the specific parking sensor module 20a with the average sensor reference value of adjacent parking sensor modules 20 operating normally Since it is possible to immediately determine whether or not to do so, it is possible to accurately determine failure and correct errors, thereby reducing maintenance costs and increasing reliability of the parking sensor module 20.

If an error occurs as a result of the corresponding communication test, information on the communication unit where the error occurred and its status is collected, the final test result is generated, and then displayed to the manager or transmitted to the parking service server.

If there is no error as a result of the communication test, the sensor test is performed.

Through the parking sensor module or the parking service server, the parking sensor module checking device collects the measurement result of each sensor and the vehicle judgment result transmitted by the parking sensor module to identify error information.

If the error occurs for the first time and is not within the fault range, the parking sensor module inspection device requests the parking sensor module to be inspected to update the reference value for each sensor according to the manager's input or a preset inspection schedule. It is possible to use a preset initial value as a sensor reference value update request, but in this case, a separate optimization setting process may be required and the characteristics of the location are not reflected at all. Request the parking service server that remotely manages the sensor module to update the sensor reference value of the parking sensor module to be inspected to the average sensor reference value of the area where the parking sensor module to be inspected is located, or receive the average sensor reference value from the parking service server It is directly provided to the parking sensor module as sensor reference value update information.

The parking sensor module updates the sensor reference value by receiving the sensor reference value update information provided by the parking service server or the parking sensor module inspection device according to the sensor reference value update request, and then obtains the measured value targeting the reference panel again and updates the updated Measurement results and vehicle determination results are calculated using the sensor reference values and directly provided to the parking sensor module inspection device or transmitted to the parking service server.

The parking sensor module inspection device that receives the second measurement result and the vehicle determination result directly or indirectly through the parking service server collects the measurement result of each sensor and the vehicle determination result transmitted through the additional sensing step to determine an error Information about the next sensor with an error and its status, and if there is no object with an error, information that there is no error are generated as the final inspection result and displayed to the manager or transmitted to the parking service server.
