Description

Technical Field

[0001] The present invention relates to the field of intelligent ground locks, and in particular to an intelligent ground lock remote control and fault self-checking system. Background Art

[0002] With the rapid development of smart cities and Internet of Things technologies, smart ground locks, as an important part of smart city traffic management, are gaining more and more attention for their remote control and fault self-checking technologies. Smart ground locks can not only provide convenient parking services, but also effectively manage parking resources and improve the utilization rate of parking spaces. However, in actual applications, smart ground locks face many challenges, including how to ensure the stability and real-time performance of remote control, how to accurately and quickly self-check faults, and how to optimize the working status of ground locks in different environments.

[0003] Existing intelligent ground lock remote control technologies often have problems with unstable communication connections and slow response speeds. Especially in complex urban environments, signal interference and changes in communication distance will seriously affect the quality of data transmission between the ground lock and the control center. In addition, current ground lock systems usually rely on manual inspections or user feedback for fault self-detection, which is not only inefficient, but also difficult to detect and handle faults in a timely manner. At the same time, existing technologies are also insufficient in automatically adjusting the working status of ground locks, and are unable to respond flexibly and quickly based on real-time environmental conditions and vehicle status.

[0004] In order to solve the above problems, this study proposed an intelligent ground lock remote control and fault self-detection system. Summary of the invention

The third instruction action includes unlocking, locking, and status display, and supports instructions for automatically adjusting the working status of the smart ground lock according to the environmental conditions and / or vehicle status, including automatic locking after the vehicle leaves, and automatic unlocking and falling when the vehicle approaches; in response to the third instruction action, identity authentication information uniquely corresponding to the smart ground lock is generated, and the identity authentication information is updated to the trigger source.

[0007] Optionally, in a first implementation of the first aspect of the present invention, the trigger information is obtained, and a first instruction action is entered in response to the trigger information. The first instruction action includes obtaining real-time trigger source distance information. If the real-time trigger source distance information is greater than a preset threshold, a first communication connection is established, otherwise a second communication connection is established, including: obtaining trigger information, the trigger information includes that the trigger source sends a request to the smart ground lock, and the real-time trigger source distance information is less than a preset threshold; dynamically adjusting the preset threshold according to environmental changes, and setting the signal interference index to SII, then:

[0008]

[0009] Among them, γ and δ are weight coefficients, satisfying γ+δ=1; N error is the number of communication errors in the recent period; N total is the total number of communications in the recent period; S signal is the current signal strength; S max is the theoretical maximum signal strength;

[0013] In an environment with large signal interference, the system automatically increases the preset threshold DTV to avoid frequent establishment of communication connections. In an environment with small signal interference, the preset threshold DTV is lowered to improve the response speed of the smart lock. Edge computing nodes are deployed near the smart ground lock. The nodes process data from the smart ground lock in real time and respond quickly. When the trigger source sends a request instruction to the smart ground lock, the instruction is first sent to the nearest edge computing node, and then quickly forwarded to the smart ground lock by the node. Real-time trigger source distance information is obtained, including the real-time distance between the smart ground lock and the trigger source, and the distance is obtained based on the signal attenuation model using the wireless communication signal strength. If the real-time trigger source distance information is greater than the preset threshold, it means that the trigger source is far away from the smart ground lock. At this time, a first communication connection is established. The first communication connection includes 4G / 5G and Wi-Fi direct connection to ensure the stability and response speed of remote control. If the real-time trigger source distance information is less than or equal to the threshold, it means that the trigger source is near the smart ground lock.

[0037] The embodiment of the present invention provides a remote control and fault self-checking system for intelligent ground locks, which improves the remote control performance, fault self-checking capability and environmental adaptability of intelligent ground locks by dynamically adjusting the communication connection strategy, collecting and analyzing the ground lock operation data in real time, establishing a fault diagnosis rule base and automatically adjusting the working state of the ground lock. The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than that illustrated or described here. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0038] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 An embodiment of the intelligent ground lock remote control and fault self-checking method in the embodiment of the present invention includes:

[0039] 101. Acquire trigger information, respond to the trigger information, and enter a first instruction action, wherein the first instruction action includes acquiring real-time trigger source distance information, and if the real-time trigger source distance information is greater than a preset threshold, establish a first communication connection, otherwise establish a second communication connection;

[0040] It is understandable that the execution subject of the present invention may be a smart lock remote control and fault self-checking system, or a terminal or a server, which is not limited here. The embodiment of the present invention is described by taking a server as the execution subject as an example.

[0041] It should be noted that to obtain trigger information: the trigger source (such as the user's mobile phone) sends a request signal to the smart lock, which contains the unique identifier of the trigger source and the request type (such as unlocking, status query, etc.). After receiving the request signal, the smart lock recognizes it as valid trigger information.

[0042] Respond to the trigger information and enter the first command action: The control system inside the smart lock responds to the trigger information and starts the execution process of the first command action. As part of the first command action, the smart lock first obtains the real-time trigger source distance information. This can be achieved through built-in sensors (such as distance sensors) or by estimating the strength of the communication signal. For example, the smart lock can measure the RSSI (received signal strength indication) value of the received trigger source signal and convert it into distance information.

[0043] Determine the distance and establish a communication connection: The preset threshold is set to 5 meters, which is set according to the needs of system design and actual application scenarios (such as parking lots, private residences, etc.).

[0044] If the real-time trigger source distance information indicates that the trigger source is greater than 5 meters away from the smart lock, the system decides to establish a first communication connection. The first communication connection can be a long-distance wireless communication method, such as 4G / 5G or Wi-Fi direct connection, to ensure stable communication at a longer distance.

[0045] On the contrary, if the real-time trigger source distance information is less than or equal to 5 meters, the system establishes a second communication connection. The second communication connection usually adopts a short-range wireless communication method, such as Bluetooth Low Energy (BLE) or NFC (Near Field Communication), which provides higher communication efficiency and security in a short distance.

[0046] Specific data example: When the trigger source is 7 meters away from the smart ground lock, the RSSI value measured by the smart ground lock is -65dBm. According to the system's built-in RSSI-distance conversion algorithm, the approximate distance corresponding to this value is 6.8 meters (note: the actual conversion may be affected by the environment and deviate). Since 6.8 meters is greater than the preset threshold of 5 meters, the smart ground lock decides to establish the first communication connection. The system sends a request to the remote server through the built-in 4G module and waits for the server's response. After receiving the request, the remote server processes the request and sends instructions or data to the smart ground lock as needed. At the same time, the server can also record the information of this interaction for subsequent analysis and management.

[0047] 102. In response to the first communication connection, obtain real-time operation data of the smart ground lock, including lock body status, battery power, and communication signal strength, and obtain a real-time fault self-check result according to the real-time operation data of the smart ground lock. If it is determined that there is no fault according to the real-time fault self-check result, re-enter the first instruction action;

[0048] It should be noted that the smart lock has established a first communication connection according to the above conditions, for example, a connection is established with a remote server through a 4G network. The remote server sends a data request instruction to the smart lock through the first communication connection, requesting to obtain real-time operation data of the smart lock.

[0049] Get real-time operation data: After receiving the data request command, the smart lock starts to collect real-time operation data. Real-time operation data includes lock body status (such as locked, unlocked, abnormal lock, etc.), battery power (such as remaining power percentage), communication signal strength (such as RSSI value or signal-to-noise ratio, etc.).

[0050] Specific data: Lock status: locked (indicated by status code "01"); Battery power: remaining power 75% (indicated by value "75"); Communication signal strength: RSSI value is -70dBm (indicated by value "-70");

[0051] Real-time fault self-check: The smart lock compares the collected real-time operation data with the preset normal range to determine whether there is a fault. For example, the normal range of the lock body status is "locked" or "unlocked", the normal range of battery power is 20% to 100%, and the normal range of communication signal strength is -60dBm to -90dBm (the specific range depends on the actual environment and device capabilities).

[0052] Determine the fault and re-enter the first command action: Based on the comparison result, the smart ground lock obtains the real-time fault self-test result. In this example, the lock body state is "locked", the battery power is 75%, both within the normal range; the communication signal strength is -70dBm, which is also within the normal communication range, so it is determined to be fault-free. The smart ground lock sends the real-time fault self-test result of no fault back to the remote server through the first communication connection so that the server can understand the current state of the ground lock.

[0053] After completing the fault self-check, if there is no fault, the intelligent lock re-enters the first instruction action.

[0054] 103. If the real-time fault self-check result determines that there is a fault, switching to a second command action, the second command action includes forced lowering and locking of the intelligent ground lock, forced raising and locking of the intelligent ground lock, and remote fault repair;

[0055] It should be noted that real-time fault self-check: Data collection: The smart ground lock collects data such as the current lock body status, battery power, and communication signal strength. Lock body status: abnormal (for example, the sensor detects that the lock body is not locked normally); Battery power: 15% (lower than the minimum power threshold required for normal operation); Communication signal strength: normal (does not affect fault judgment); Fault judgment: The ground lock compares the collected data with the preset fault threshold; Abnormal lock body status and low battery power are both considered faults.

[0056] Switch to the second command action. Since the real-time fault self-check result determines that there is a fault, the smart lock automatically executes the following second command action:

[0057] Force the intelligent floor lock to fall down and lock: The system controls the lock body drive mechanism and tries to force the lock body to fall down to the locked state to ensure safety. After the lock is successfully locked, a lock confirmation signal is sent to the remote server.

[0058] Or force the intelligent floor lock to lift and lock (depending on the specific fault type and scenario requirements): If the fault causes the lock body to fail to fall normally, the system can try to force the lock body to lift and lock. This action is to prevent the lock body from getting stuck in the middle position, causing safety hazards.

[0059] Remote fault reporting: The smart lock sends a repair request containing detailed fault information to the remote server through the established first communication connection (such as 4G network). The repair request data includes: fault type (abnormal lock state, low battery), fault occurrence time, lock body unique identifier, etc. After receiving the repair request, the remote server records the fault information and notifies the maintenance personnel to go to the site for inspection.

[0060] 104. Responding to the second communication connection, obtaining a user terminal operation request, environmental condition information, and vehicle status information, and generating a third instruction action according to the user terminal operation request, environmental condition information, and vehicle status information, wherein the third instruction action includes unlocking, locking, and status display, and supports instructions for automatically adjusting the working state of the smart ground lock according to the environmental condition and / or vehicle status, including automatically locking after the vehicle leaves, and automatically unlocking and lowering when the vehicle approaches;

[0061] It should be noted that when a user brings a smartphone (as a user terminal) close to the smart lock and the distance between the two is less than a preset threshold (such as 5 meters), the smart lock establishes a second communication connection with the user's smartphone through a built-in Bluetooth Low Energy (BLE) module.

[0062] Obtaining user terminal operation request: The user sends an operation request to the smart lock through the application on the smartphone. In this example, the user requests to unlock the lock.

[0063] Specific data example: User terminal operation request: unlock (expressed as instruction code "001");

[0064] Obtain environmental status information and vehicle status information. The smart ground lock obtains current environmental status information and vehicle status information from built-in environmental sensors and vehicle detection sensors at the same time.

[0065] Specific data examples: Environmental condition information: temperature 25°C, humidity 40%, no rainfall (expressed as a series of numerical values ​​and status codes); Vehicle status information: the vehicle is approaching (detected by the geomagnetic sensor, expressed as status code "10");

[0066] Generate a third instruction action. Based on the operation request of the user terminal, the environmental condition information and the vehicle status information, the control system of the smart lock generates the third instruction action.

[0067] Unlock: According to the user's operation request, the smart ground lock performs the unlocking action. Status display: The smart ground lock displays the current status as "unlocked" through the LED indicator or the mobile phone screen. Automatic adjustment of working status: As the vehicle approaches, the smart ground lock remains unlocked and is ready to automatically lock after the vehicle leaves.

[0068] Execute subsequent actions: After the user drives the vehicle out of the ground lock range, the ground lock detects that the vehicle has left through the vehicle detection sensor. The smart ground lock automatically performs the locking action and confirms "locked" through the status display.

[0069] 105. In response to the third instruction action, generate identity authentication information uniquely corresponding to the smart lock, and update the identity authentication information to the trigger source;

[0070] It should be noted that the smart lock has generated a third instruction action, such as unlocking, according to the operation request of the user terminal, environmental condition information and vehicle status information.

[0071] Generate authentication information, unique identifier: The smart lock has a unique identifier (such as a serial number or MAC address) inside to identify the uniqueness of the lock. In this example, the unique identifier is set to "LockID_12345".

[0072] Dynamic verification code: To enhance security, the smart lock will also generate a dynamic verification code. This verification code can be a one-time password generated based on a timestamp, a random number, or other algorithms. For example, the current timestamp is "1677224834" (representing a specific time point), and the smart lock uses this timestamp as a seed to generate a dynamic verification code "Code_A5B6" through an encryption algorithm.

[0073] Combined authentication information: Combine the unique identifier and the dynamic verification code to form a complete authentication information. In this example, the combined authentication information is "LockID_12345:Code_A5B6".

[0074] Update the authentication information to the trigger source and send the authentication information: The smart lock sends the generated authentication information to the trigger source, that is, the user's smartphone, through the second communication connection (such as Bluetooth BLE). Trigger source reception and storage: After the user's smartphone receives the authentication information, it stores it in the local cache or a specific application for subsequent use.

[0075] Verification and application: When the user needs to interact with the smart lock again (such as remote status query or control), the smartphone will provide the stored authentication information for verification. The smart lock will verify whether the received authentication information is valid and decide whether to allow further interaction based on it.

[0076] In an embodiment of the present invention, by responding to different trigger information, the first or second communication connection is intelligently established, and a fault self-check is performed or an action requested by the user is executed according to real-time data. Specifically, the system first obtains the trigger information, and according to the distance between the trigger source and the smart ground lock, chooses to establish a long-distance first communication connection or a short-distance second communication connection. After establishing the first communication connection, the system can remotely obtain the real-time operating data of the smart ground lock, perform a fault self-check, and re-enter the waiting state in the absence of a fault. If a fault is detected, the system will execute the second instruction action, including forced locking or unlocking and remote repair. When establishing the second communication connection, the system responds to the operation request of the user terminal, while considering the environmental conditions and the vehicle status, generates and executes the third instruction action, such as unlocking, locking, etc., and supports automatic adjustment of the working status. Finally, to enhance security, the system will generate identity authentication information that uniquely corresponds to the smart ground lock and update it to the trigger source. The present invention can intelligently select a communication mode according to the distance of a trigger source, which not only ensures the feasibility of remote control, but also optimizes the efficiency of short-range communication; by acquiring the ground lock operation data in real time and performing fault self-checking, the system can promptly discover and handle potential problems, thereby improving the stability and reliability of the ground lock; an identity authentication method combining a dynamic verification code and a unique identifier is adopted, which significantly improves the security of the system and prevents unauthorized access and operation; it supports automatic adjustment of the working state according to environmental conditions and vehicle status, such as automatic unlocking when the vehicle approaches and automatic locking after leaving, which greatly improves the user's convenience and experience; through the first communication connection, the remote server can understand the ground lock status in real time and record the interaction information, which is convenient for subsequent data analysis and management, and also facilitates maintenance personnel to respond to repair requests in a timely manner.

Acquire trigger information, respond to the trigger information, and enter the first command action, wherein the first command action includes acquiring real-time trigger source distance information, and if the real-time trigger source distance information is greater than a preset threshold, establish a first communication connection, otherwise establish a second communication connection, wherein the preset threshold is dynamically adjusted according to the signal interference index, and when the signal interference exceeds a preset intensity of one (-70 dBm (decibel milliwatts)), the preset threshold is automatically increased to avoid frequent establishment of communication connections, and when the signal interference is less than a preset intensity of two (-85 dBm), the preset threshold is lowered to increase the response speed of the smart lock;

[0079] Specifically, the trigger information is obtained, and the trigger information includes that the trigger source sends a request to the smart ground lock and the real-time trigger source distance information is less than the preset threshold; the preset threshold is dynamically adjusted according to environmental changes, and the signal interference index is set to SII, then:

[0080]

[0081] Among them, γ and δ are weight coefficients, satisfying γ+δ=1; N error is the number of communication errors in the recent period; N total is the total number of communications in the recent period; S signal is the current signal strength; S max is the theoretical maximum signal strength;

[0082] Set the dynamically adjusted preset threshold to DTV:

[0083] DTV=D base +k·SII

[0084] Among them, D base The basic preset threshold is the preset distance threshold in a non-interference or standard environment; k is the adjustment coefficient used to control the impact of SII on DTV;

[0085] In an environment with large signal interference, the system automatically increases the preset threshold DTV to avoid frequent establishment of communication connections. In an environment with small signal interference, the preset threshold DTV is lowered to improve the response speed of the smart lock. Edge computing nodes are deployed near the smart ground lock. The nodes process data from the smart ground lock in real time and respond quickly. When the trigger source sends a request instruction to the smart ground lock, the instruction is first sent to the nearest edge computing node, and then quickly forwarded to the smart ground lock by the node. Obtain real-time trigger source distance information, including the real-time distance between the smart ground lock and the trigger source, and use the wireless communication signal strength to obtain the distance according to the signal attenuation model. If the real-time trigger source distance information is greater than the preset threshold, it means that the trigger source is far away from the smart ground lock. At this time, a first communication connection is established. The first communication connection includes 4G / 5G and Wi-Fi direct connection to ensure the stability and response speed of remote control. If the real-time trigger source distance information is less than or equal to the threshold, it means that the trigger source is near the smart ground lock. At this time, a second communication connection is established. The second communication connection includes Bluetooth low energy consumption BLE and NFC.

[0086] It should be noted that this embodiment will describe in detail how to dynamically adjust the preset threshold, obtain real-time trigger source distance information, and choose to establish different types of communication connections based on this information in the smart floor lock remote control and fault self-detection system.

[0087] System initialization, basic preset threshold D baseIt is set to 5 meters, which is the distance at which the smart lock can communicate stably in an interference-free or standard environment. The adjustment coefficient k is set to 0.5 to control the impact of the signal interference index SII on the dynamically adjusted preset threshold DTV. The weight coefficient γ is set to 0.6 and δ is set to 0.4, reflecting the relative importance of communication error rate and signal strength in SII.

[0088] Environmental monitoring and SII calculation, the system detected that there were 10 communication errors in the last 100 communications, that is, N error =10, N total =100. Current signal strength S signal The theoretical maximum signal strength is -70dBm. max is -40dBm. Calculated according to the SII formula:

[0089]

[0090] Dynamically adjust the preset threshold value, according to the DTV formula: DTV = 5 + 0.5 × 0.22 = 5.11 meters, the system automatically adjusts the preset threshold value to 5.11 meters.

[0091] Trigger information acquisition and response: The trigger source (such as the user's mobile phone) sends a request command to the smart lock. The command is first sent to the edge computing node deployed near the smart lock, and the node quickly forwards it to the smart lock.

[0092] Real-time trigger source distance information acquisition, the smart ground lock measured the real-time signal strength of the trigger source to be -65dBm. Using the signal attenuation model, the smart ground lock estimated the real-time distance to the trigger source to be about 4.8 meters.

[0093] The communication connection is established. Since the real-time trigger source distance information (4.8 meters) is less than the dynamically adjusted preset threshold (5.11 meters), the system determines that the trigger source is near the smart lock. Therefore, the system establishes a second communication connection, namely a Bluetooth low energy BLE connection, to achieve low-power and fast near-field communication.

[0094] 202. In response to the first communication connection, obtain real-time operation data of the smart ground lock, including lock body status, battery power, and communication signal strength, and obtain a real-time fault self-check result according to the real-time operation data of the smart ground lock. If it is determined that there is no fault according to the real-time fault self-check result, re-enter the first instruction action;

[0095] Specifically, in response to the first communication connection, the smart lock collects and uploads operation data in real time, including: lock body status: unlocked, locked, locked status; battery power: percentage of remaining power; communication signal strength: RSSI value; the remote server receives the data uploaded by the smart lock, performs real-time processing and analysis, and implements fault self-checking, including: cleaning, verifying and formatting the received data; judging whether the state of the smart lock is abnormal through logic, including long-term non-response and frequent unlocking; setting a low power threshold, and determining it as abnormal when the power is lower than the threshold; setting a weak signal threshold, and determining it as communication abnormality when it is lower than the threshold; establishing a fault diagnosis rule base, including fault judgment conditions and processing methods, if the battery power is low and the communication signal is weak, it is determined to be a possible power supply or communication module failure, if the lock body state is abnormal and reported frequently, it is determined to be a mechanical failure or sensor failure; generating real-time fault self-checking results based on real-time operation data and fault diagnosis rules;

[0096] It should be noted that when establishing the first communication connection, the distance between the trigger source (such as the user's mobile phone) and the smart lock is measured to be 10 meters, which is greater than the dynamically adjusted preset threshold (for example, 5.11 meters). Therefore, the system establishes the first communication connection and uses 4G / 5G or Wi-Fi direct connection to ensure the stability and response speed of remote control.

[0097] The intelligent ground lock collects and uploads operation data in real time. Lock status: currently in "locked" status. Battery power: the remaining power percentage is 25%. Communication signal strength: the received signal strength indication (RSSI) value is -80dBm.

[0098] The remote server receives and processes the data, and the server successfully receives the real-time operation data uploaded by the smart lock. The data is cleaned, verified, and formatted to ensure data accuracy and consistency.

[0099] Realize fault self-check and logical judgment: the smart lock is currently responding normally, and there is no long-term non-response or frequent unlocking. Battery power check: set the low power threshold to 20%, the current power (25%) is higher than the threshold, and the battery status is judged to be normal. Communication signal strength check: set the signal weak threshold to -85dBm, the current RSSI value (-80dBm) is higher than the threshold, and the communication status is judged to be normal.

[0100] Fault diagnosis rule base application, according to the established fault diagnosis rule base, analyzes the current data and does not trigger any fault judgment conditions. For example, there is no combination of "low battery and weak communication signal" or "abnormal lock status and frequent reporting".

[0101] Generate real-time fault self-check results. Based on real-time operation data and fault diagnosis rules, the system generates real-time fault self-check results: the smart ground lock is operating normally and there is no fault. The server feeds this result back to the trigger source (such as the user's mobile phone) and continues to monitor the smart ground lock in real time.

[0102] 203. If the real-time fault self-check result determines that there is a fault, switching to a second command action, the second command action includes forced lowering and locking of the intelligent ground lock, forced raising and locking of the intelligent ground lock, and remote fault repair;

[0103] Specifically, if the real-time fault self-check result determines that a fault exists, the fault response logic is triggered, and the response logic determines which second instruction action to execute based on the fault type and preset rules; the second instruction action is implemented, including: forcibly dropping the smart ground lock and locking it: after the smart ground lock receives the instruction, the controller controls the actuator to perform the dropping action, and confirms through the sensor that the smart ground lock has been dropped, and then locks it. At the same time, the smart ground lock sends the execution result and the current state back to the remote server and the user terminal; forcibly raising the smart ground lock and locking it: after the smart ground lock receives the instruction, the controller controls the actuator to perform the raising action, and confirms through the sensor that the smart ground lock has been raised, and then locks it. The smart ground lock sends the execution result and the current state back to the remote server and the user terminal; remote fault reporting: generate reporting information based on the fault self-check result, including the fault type, fault time, and smart ground lock location, and send the reporting information to the user terminal or the maintenance personnel's mobile terminal, and the user or maintenance personnel perform fault troubleshooting and repairs based on the reporting information;

[0104] It should be noted that the real-time fault self-check result: the system found an abnormality in the smart ground lock through fault self-check, and the specific fault type was "communication abnormality". The RSSI value continued to be lower than the set signal weak threshold (-90dBm), and it was determined to be a communication fault. The fault occurred at XX hours and XX minutes, and the specific location of the smart ground lock was "in front of No. XX, XX Street".

[0105] The fault response logic is triggered. According to the fault type "communication abnormality" and the preset rules, the system decides to execute two second instruction actions: "remote fault repair" and "force the intelligent ground lock to drop and lock". In the preset rules, communication failure may cause remote control failure. To ensure safety, the ground lock must be forced to drop and lock first to prevent unauthorized access.

[0106] Force the smart lock to drop and lock: After the smart lock receives the "force drop" command, the controller immediately controls the actuator to perform the drop action. Through the built-in sensor, the system confirms that the smart lock has successfully dropped to the locked position. The smart lock sends the execution result "dropped and locked" and the current status information back to the remote server and the user's mobile terminal so that the user can understand the current situation.

[0107] Remote fault reporting: The system automatically generates repair information based on the fault self-check results, including the fault type "communication abnormality", fault time "XX hour XX minute", and smart ground lock location "in front of No. XX, XX street". The repair information is sent to the user's mobile terminal and the maintenance personnel's mobile terminal through the system. After receiving the repair information, the user and maintenance personnel can conduct fault troubleshooting and repair arrangements based on the information provided.

[0108] Subsequent processing: Maintenance personnel went to the site for inspection and repair, confirmed that the communication failure was caused by external interference, and made necessary adjustments and optimizations to the smart ground lock. After the repair was completed, the smart ground lock resumed normal communication function, and the system re-entered the first command action, waiting for the next trigger.

[0109] 204. Responding to the second communication connection, obtaining a user terminal operation request, environmental condition information, and vehicle status information, and generating a third instruction action according to the user terminal operation request, environmental condition information, and vehicle status information, wherein the third instruction action includes unlocking, locking, and status display, and supports instructions for automatically adjusting the working state of the intelligent ground lock according to the environmental condition and / or vehicle status, including automatically locking after the vehicle leaves, and automatically unlocking and lowering when the vehicle approaches;

[0110] Specifically, in response to the second communication connection, a user terminal operation request, environmental condition information and vehicle status information are obtained, wherein the user initiates a user terminal operation request through a trigger source, and the environmental sensor on the smart ground lock collects environmental condition information in real time, including temperature and humidity, light intensity, and whether the smart ground lock detects the presence of the vehicle through an infrared or pressure sensor; a third instruction action is generated based on the user terminal operation request, environmental condition information and vehicle status information: if the user requests to unlock, an unlock instruction is generated; if the user requests to lock and the vehicle has left, a locking instruction is generated, and the smart ground lock state is automatically adjusted according to the environmental condition and the vehicle state; in the automatic adjustment of the smart ground lock state according to the environmental condition and the vehicle state, the distance between the vehicle and the ground lock is set to D:

[0111]

[0112] Among them, (x v ,y v ) represents the coordinates of the vehicle, (x l ,y l ) represents the coordinates of the ground lock; when D is less than a certain threshold D th When D is greater than D th And if the vehicle was approaching before, it is considered to be leaving;

[0113] E f =α·W r+β·T e +λ·H u +∈·O c

[0114] Among them, E f Indicates the environmental condition influencing factor, W r Indicates weather conditions, T e Indicates the ambient temperature, H u Indicates the ambient humidity, O c represents other environmental conditions, including light intensity and whether there are obstacles. α, β, λ,∈ are weight coefficients;

[0115] S new =f(D,E f , S old , V s )

[0116] Among them, S new represents the new ground lock state, including unlocked state and locked state. f represents the decision function, which comprehensively considers the distance D between the vehicle and the ground lock and the environmental condition influencing factor E. f 、Current ground lock status S old and the vehicle state V s , including whether the vehicle is started and whether the door is closed;

[0117] According to S new Automatically adjust the state of the smart ground lock; the smart ground lock uploads the execution result and current state to the cloud server, and notifies the trigger source of the operation result;

[0118] It should be noted that in response to the second communication connection, the smart lock establishes a second communication connection with the user terminal (such as a smartphone App, a key card) through the wireless communication module. The user initiates a user terminal operation request, such as requesting to unlock, through a trigger source (such as an App interface button).

[0119] Obtaining environmental information and vehicle status information: The environmental sensors on the smart lock collect environmental information in real time: The temperature and humidity sensors detect that the current ambient temperature is 25°C and the humidity is 60%. The light sensor detects that the current light intensity is 500 lux. The smart lock detects the presence of the vehicle through the infrared sensor and obtains the vehicle status information: the vehicle is started and the door is closed.

[0120] The vehicle coordinates obtained through the vehicle positioning system are (100,200).

[0121] The third instruction action is generated based on the information obtained. The user requests to unlock the vehicle, and the vehicle has started and is close to the ground lock (according to the distance calculation formula, the distance D between the vehicle and the ground lock is less than the set threshold D th ), thus generating an unlock instruction.

[0122] At the same time, the system calculates the environmental impact factor E based on the environmental information f :

[0123] Set weather conditions r It is a sunny day (assigned as 1), and the ambient temperature is T e The ambient temperature is 25℃ and the humidity is H u 60%, light intensity 500 lux (other environmental conditions O c Assigned to 1), weight coefficients α, β, λ,∈ are 0.3, 0.2, 0.2, 0.3 respectively. Then E f =0.3×1+0.2×25+0.2×60+0.3×1=23.6.

[0124] The system comprehensively considers the distance D between the vehicle and the ground lock and the environmental condition influencing factor E according to the decision function f. f 、Current ground lock status S old (set to locked state) and vehicle state V s (started, car door closed), determine the new ground lock status S new It is in unlocked state.

[0125] Automatically adjust the state of the smart lock and execute the command. After the smart lock receives the unlock command, the controller controls the actuator to perform the unlocking action. After the unlocking is successful, the smart lock uploads the execution result (unlocked) and the current status information to the cloud server. At the same time, the operation result (unlocking success) is notified to the user terminal through the second communication connection (such as the App displays the unlocking success message).

[0126] Subsequent monitoring and automatic adjustment: During vehicle use, the intelligent ground lock continuously monitors environmental information and vehicle status information. th When the vehicle is approaching and the automatic locking conditions are met (such as the user does not request to keep the unlocked state through the terminal), the smart ground lock will automatically perform the locking action. All execution results and status changes will be uploaded to the cloud server in real time and notified to the user terminal.

[0127] 205. In response to the third instruction action, generate identity authentication information uniquely corresponding to the smart lock, and update the identity authentication information to the trigger source;

[0128] Specifically, in response to the third instruction action, a unique identifier of the target smart lock is obtained; a unique, time-limited authentication information is generated based on the authentication server using an encryption algorithm and the unique identifier of the target smart lock, the authentication information includes the smart lock ID, generation timestamp, validity period, and encrypted signature field; the third instruction action is encapsulated together with the generated authentication information into a data packet; the data packet is sent to the smart lock using a communication protocol, and after the smart lock receives the data packet, the instruction and authentication information are parsed, and the smart lock uses a pre-stored key or algorithm to verify the validity of the authentication information, including verifying whether the signature in the Token is correct, checking whether the Token is expired, and ensuring that the smart lock ID in the Token matches the local ID; if the authentication information is valid, the smart lock executes the instruction action, and the smart lock uploads the instruction execution result and its current status to the cloud server; after receiving the feedback, the cloud server updates the authentication information status associated with the smart lock and the trigger source to obtain new or updated authentication information; the new or updated authentication information is pushed back to the trigger source, and the authentication information record of the smart lock is updated in the authentication server and secure storage;

[0129] It should be noted that, in response to the third instruction action, the user initiates an unlocking request through the user terminal (such as a smartphone App), and the request is received by the system as the third instruction action.

[0130] Obtain the unique identifier of the target smart lock, and the system determines the unique identifier (ID) of the target smart lock, such as "LockID12345".

[0131] Generate authentication information. The authentication server uses an encryption algorithm (such as HMAC-SHA256) and the unique identifier of the smart lock to generate a unique, time-limited authentication information (Token).

[0132] The token contains the following fields:

[0133] Smart ground lock ID: LockID12345;

[0134] Generate timestamp: 2023-04-0110:00:00;

[0135] Validity period: 300 seconds (5 minutes);

[0136] Encrypted signature: abcdef1234567890 (set signature result);

[0137] The system encapsulates the third instruction action (unlock request) and the generated authentication information (Token) into a data packet and sends the data packet to the smart lock using a communication protocol (such as MQTT).

[0138] The smart lock receives and verifies the authentication information. After receiving the data packet, the smart lock parses the instruction and authentication information. Use the pre-stored key or algorithm to verify the validity of the Token: Verify whether the signature is correct: Compare the locally calculated signature with the signature in the Token to confirm consistency. Check whether the Token is expired: Compare the current time with the generation timestamp and validity period in the Token to confirm that the Token has not expired. Ensure that the smart lock ID in the Token matches the local ID: Compare the smart lock ID in the Token with the locally stored ID to confirm consistency.

[0139] Execute the command action and feedback. If the identity authentication information is valid, the smart lock executes the unlock command action. The smart lock uploads the command execution result (unlocking success) and its current status (unlocked) to the cloud server.

[0140] Update the authentication information status. After receiving the feedback, the cloud server updates the authentication information status associated with the smart lock and the trigger source. Generate new or updated authentication information, such as updating the validity period and signature.

[0141] Push the new authentication information back to the trigger source and push the new authentication information back to the user terminal (such as the App displays the updated Token information).

[0142] Update the authentication information record, and update the authentication information record of the smart lock in the authentication server and secure storage at the same time to ensure that the latest information is used for the next verification.

[0143] In the embodiment of the present invention, precise control and security of the intelligent ground lock are achieved by dynamically adjusting the preset threshold, real-time monitoring of environmental conditions and vehicle status, and generation and verification of identity authentication information. The specific steps include obtaining trigger information, establishing different types of communication connections according to the trigger information, performing fault self-checking, generating command actions according to user requests and environmental and vehicle status, and performing identity authentication before executing the command. This series of processes ensures that the intelligent ground lock can respond correctly in various situations, improving the intelligence and security of the system. Through the generation and verification of identity authentication information, it is ensured that only authorized users can control the intelligent ground lock, effectively preventing illegal access and operation. The working state of the ground lock can be automatically adjusted according to environmental changes and vehicle status, such as automatically unlocking when the vehicle approaches and automatically locking when leaving, which improves user experience and convenience. By dynamically adjusting the preset threshold, the system can select the most appropriate communication connection mode in different environments, ensuring the stability and response speed of remote control. Through real-time monitoring and fault self-checking functions, the system can detect and report faults in a timely manner, which is convenient for maintenance personnel to quickly locate and solve problems. Through data collection and analysis of cloud servers, real-time monitoring and management of the use of intelligent ground locks can be achieved, which helps to optimize resource allocation and reduce maintenance costs. In summary, this technology improves the security, intelligence level, response speed and resource management efficiency of smart ground locks through intelligent remote control and fault self-detection functions, providing users with a more convenient and safe parking service experience.

[0144] The above describes the remote control and fault self-checking method of the intelligent ground lock in the embodiment of the present invention. The following describes the remote control and fault self-checking system of the intelligent ground lock in the embodiment of the present invention. Figure 3In one embodiment of the present invention, an embodiment of the remote control and fault self-checking system of the intelligent ground lock includes: a trigger module 301, which is used to obtain trigger information, respond to the trigger information, and enter a first instruction action, wherein the first instruction action includes obtaining real-time trigger source distance information, and if the real-time trigger source distance information is greater than a preset threshold, a first communication connection is established, otherwise a second communication connection is established; a processing module 302, which is used to respond to the first communication connection, obtain real-time operation data of the intelligent ground lock, including lock body status, battery power, and communication signal strength, and obtain a real-time fault self-checking result based on the real-time operation data of the intelligent ground lock, and if it is determined that there is no fault based on the real-time fault self-checking result, re-enter the first instruction action; a fault module 303, which is used to switch to if the real-time fault self-checking result determines that there is a fault, The second instruction action, the second instruction action includes forced lowering of the smart ground lock and locking, forced raising of the smart ground lock and locking, and remote fault reporting; an allocation module 304, used to respond to the second communication connection, obtain the user terminal operation request, environmental condition information and vehicle status information, and generate a third instruction action based on the user terminal operation request, environmental condition information and vehicle status information, the third instruction action includes unlocking, locking, and status display, and supports instructions for automatically adjusting the working status of the smart ground lock according to the environmental condition and / or vehicle status, including automatic locking after the vehicle leaves, and automatic unlocking and falling when the vehicle approaches; an update module 305, used to generate identity authentication information uniquely corresponding to the smart ground lock in response to the third instruction action, and update the identity authentication information to the trigger source.

[0145] In the embodiment of the present invention, five core modules are included: a trigger module, a processing module, a fault module, a distribution module and an update module. This system accurately obtains trigger information and intelligently selects to establish different communication connections based on the real-time trigger source distance information. The system can monitor the operating status of the intelligent ground lock in real time, perform fault self-checking, and take corresponding actions according to the self-checking results, such as re-entering the command action or performing fault handling. At the same time, the system can also respond to the operation request of the user terminal, automatically adjust the working status of the ground lock according to the environmental conditions and vehicle status, and ensure the safety and convenience of the ground lock. In addition, the system further enhances the safety performance of the intelligent ground lock by generating and updating identity authentication information. The system can monitor the state of the ground lock in real time and perform intelligent management according to the actual situation, thereby improving management efficiency and convenience. Through the fault self-checking function, the system can timely discover and handle the ground lock fault, reducing the cost of manual inspection and maintenance, and the remote fault reporting function also greatly improves the efficiency of fault handling. The system effectively prevents illegal operation and malicious damage by generating identity authentication information uniquely corresponding to the ground lock, thereby enhancing the safety of the ground lock. The system supports automatic adjustment of the working status of the ground lock according to the environmental conditions and vehicle status, such as automatic locking after the vehicle leaves and automatic unlocking and lowering when approaching, which greatly improves the user experience. The design of five modules makes the system functions highly integrated, and at the same time, each module is relatively independent, which is convenient for system expansion and maintenance. In summary, the intelligent ground lock remote control and fault self-detection system not only improves the intelligence level of ground lock management, but also significantly enhances the safety and user-friendliness of ground locks, bringing important technological innovation and practical application value to the field of intelligent parking and vehicle safety management.
