[0057] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0058] It should be noted that the terms "including" and "having" in the embodiments of the present application and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes 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 are inherent to these processes, methods, products or devices.

[0059] This application discloses an Arduino-based smart door control method and system for smart agricultural greenhouses. This system unlocks the smart door only when the face of a legitimate operator with a task is scanned, reducing the risk of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking. This is described in detail below with reference to the accompanying figures.

[0060] See also Figure 1 , Figure 1This is a flow chart of the first embodiment of the smart door control method for a smart agricultural greenhouse based on Arduino disclosed in the embodiment of this application. Figure 1 In the smart door control method of the smart agricultural greenhouse based on Arduino, the smart door is provided with an Arduino controller, and the wearable device is worn by a certain user. It is understandable that the Arduino controller involved in the embodiment of the present application can be a controller with an Arduino UNO development board. It is understandable that the wearable device involved in the embodiment of the present application can include but is not limited to smart bracelets, smart watches, phone watches, wrist phones or headphones, and the embodiment of the present application does not limit it. Figure 1 As shown, the Arduino-based smart door control method for a smart agricultural greenhouse may include the following steps:

[0061] 101. When the user approaches the locked smart door outside the smart agricultural greenhouse, the Arduino controller uses a camera module to capture the user's facial image.

[0062] In an embodiment of the present application, a shooting module (i.e., a camera) may be provided on the Arduino controller. When the user wearing the wearable device approaches the locked smart door outside the smart agricultural greenhouse, the Arduino controller may use the shooting module to capture the user's facial image.

[0063] 102. When the Arduino controller recognizes, based on the user's facial image, that the user is a legal operator preset by the Arduino controller and allowed to enter the smart agricultural greenhouse, if it recognizes that the wearable device is playing a specified audio file, the smart door is unlocked; wherein the specified audio file is used to describe the work tasks of the legal operator after entering the smart agricultural greenhouse.

[0064] In some embodiments, when the Arduino controller recognizes a legal operator who is allowed to enter the smart agricultural greenhouse and is preset by the user for the Arduino controller based on the user's facial image, it can identify whether the unique audio ID of the target audio file being played by the wearable device broadcast by the wearable device is the same as the unique audio ID of the designated audio file preset by the Arduino controller for the wearable device; if they are the same, it is determined that the wearable device is playing the designated audio file (that is, the target audio file being played by the wearable device is the designated audio file) and the smart door is unlocked.

[0065] For example, the work task of the legal operator described in the designated audio file after entering the smart agricultural greenhouse may be to perform deep plowing and turning over the soil in certain areas to be planted in the smart agricultural greenhouse; wherein, deep plowing and turning over the soil in certain areas to be planted in the smart agricultural greenhouse can destroy the compaction in the soil, thereby preventing and improving the salinization of the soil in these areas to be planted.

[0066] It can be seen that implementation Figure 1 In the Arduino-based smart door control method for a smart agricultural greenhouse shown in the figure, the smart door is unlocked only when the face of a legitimate operator with an operating task is scanned, thereby reducing the occurrence of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking.

[0067] See also Figure 2 , Figure 2 This is a flow chart of the second embodiment of the smart door control method for smart agricultural greenhouses based on Arduino disclosed in the embodiment of this application. Figure 2 In the smart door control method of the smart agricultural greenhouse based on Arduino, the smart door is provided with an Arduino controller, and the wearable device is worn by a user. Figure 2 As shown, the Arduino-based smart door control method for a smart agricultural greenhouse may include the following steps:

[0068] 201. When the user approaches the locked smart door outside the smart agricultural greenhouse, the Arduino controller uses a camera module to capture the user's facial image.

[0069] 202. When the Arduino controller recognizes, based on the user's facial image, that the user is a legal operator preset by the Arduino controller and allowed to enter the smart agricultural greenhouse, it determines a unique device ID corresponding to the preset legal operator.

[0070] Exemplarily, the unique device ID corresponding to the legal operator may include a unique MAC address corresponding to the legal operator.

[0071] 203. The Arduino controller broadcasts first interaction information including the unique device ID, where the first interaction information is used to instruct the target device to which the unique device ID belongs to report the unique audio ID of the target audio file being played by the target device.

[0072] 204. The wearable device receives the first interaction information and identifies whether the unique device ID is the same as the unique identity ID of the wearable device; if they are the same, execute step 205; if they are not the same, end this process.

[0073] Exemplarily, the unique identity ID of the wearable device may be a unique MAC address of the wearable device.

[0074] 205. The wearable device determines that the wearable device is the target device to which the unique device ID belongs, and broadcasts a first response message including the unique audio ID of the target audio file being played by the wearable device in response to the first interactive information.

[0075] 206. The Arduino controller receives the first response information and identifies whether the unique audio ID of the target audio file being played by the wearable device is the same as the unique audio ID of the specified audio file associated with the preset unique device ID; if they are the same, execute step 207; if not, end this process.

[0076] Among them, the designated audio file is used to describe the work tasks of the legal workers after entering the smart agricultural greenhouse.

[0077] 207. The Arduino controller determines that the target audio file being played by the wearable device is the designated audio file, and unlocks the smart door.

[0078] In an embodiment of the present application, the implementation of the above steps 202 to 206 enables the Arduino controller to accurately identify that the wearable device is playing a specified audio file describing the work tasks of the legal operator after entering the smart agricultural greenhouse when the Arduino controller recognizes a legal operator preset by the user for the Arduino controller based on the user's facial image, thereby accurately unlocking the smart door and reducing the occurrence of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking.

[0079] 208. The wearable device is connected to the Internet of Things management platform corresponding to the smart agricultural greenhouse.

[0080] In some embodiments, after the Arduino controller unlocks the smart door, it can broadcast a second interactive message including the unique device ID, the unique identifier of the Internet of Things management platform corresponding to the smart agricultural greenhouse, and the access verification information of the Internet of Things management platform; accordingly, the wearable device can receive the second interactive message and identify whether the unique device ID is the same as the unique identity ID of the wearable device; if they are the same, the Internet of Things management platform corresponding to the smart agricultural greenhouse is accessed according to the unique identifier of the Internet of Things management platform corresponding to the smart agricultural greenhouse and the access verification information of the Internet of Things management platform.

[0081] It is understandable that the access verification information of the Internet of Things management platform may include the access key of the Internet of Things management platform.

[0082] 209. The Arduino controller reports a request for obtaining operation instruction information including the task type of the operation task and the unique device ID to the Internet of Things management platform.

[0083] For example, when the operation task is to perform deep plowing and turning over the soil in certain areas to be planted in the smart agricultural greenhouse, the task type of the operation task is deep plowing and turning over the soil to break up compaction.

[0084] 210. The wearable device obtains the operation guidance information of the operation task that matches the task type and is issued by the Internet of Things management platform in response to the operation task guidance information acquisition request and according to the unique device ID.

[0085] For example, when the task type of the operation task is deep plowing and soil turning to break up compaction (at this time, the operation task is to perform deep plowing and soil turning operations on the soil in certain areas to be planted in the smart agricultural greenhouse), the Internet of Things management platform responds to the operation task guidance information acquisition request and matches the operation guidance information of the operation task according to the task type issued by the unique device ID, which may include a specified deep plowing and soil turning thickness (such as 50 cm) and a setting method for setting the specified deep plowing and soil turning depth (such as 50 cm) on the deep plowing and soil turning machine.

[0086] 211. The wearable device outputs the operation guidance information.

[0087] In the embodiment of the present application, implementing the above steps 202 to 206 allows the user wearing the wearable device to perform the operation task under the guidance of the operation guidance information, thereby improving the accuracy of the user's operation task.

[0088] It can be seen that implementation Figure 2In the Arduino-based smart door control method for a smart agricultural greenhouse shown in the figure, the smart door is unlocked only when the face of a legitimate operator with an operating task is scanned, thereby reducing the occurrence of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking.

[0089] See also Figure 3 , Figure 3 This is a flow chart of the third embodiment of the smart door control method for smart agricultural greenhouses based on Arduino disclosed in the embodiment of this application. Figure 3 In the smart door control method of the smart agricultural greenhouse based on Arduino, the smart door is provided with an Arduino controller, and the wearable device is worn by a user. Figure 3 As shown, the Arduino-based smart door control method for a smart agricultural greenhouse may include the following steps:

[0090] 301. When the user approaches the locked smart door outside the smart agricultural greenhouse, the Arduino controller uses a camera module to capture the user's facial image.

[0091] 302. When the Arduino controller recognizes, based on the user's facial image, that the user is a legal operator preset by the Arduino controller and allowed to enter the smart agricultural greenhouse, it determines a unique device ID corresponding to the preset legal operator.

[0092] 303. The Arduino controller broadcasts first interaction information including the unique device ID, where the first interaction information is used to instruct the target device to which the unique device ID belongs to report the unique audio ID of the target audio file being played by the target device.

[0093] 304. The wearable device receives the first interaction information and identifies whether the unique device ID is the same as the unique identity ID of the wearable device; if they are the same, execute step 305; if they are not the same, end this process.

[0094] 305. The wearable device determines that the wearable device is the target device to which the unique device ID belongs, and in response to the first interactive information, broadcasts a first response message including the unique audio ID of the target audio file being played by the wearable device and the actual playback duration of the target audio file when the wearable device receives the first interactive information.

[0095] 306. The Arduino controller receives the first response information and identifies whether the unique audio ID of the target audio file being played by the wearable device is the same as the unique audio ID of the specified audio file associated with the preset unique device ID; if they are the same, execute steps 307 to 310; if they are not the same, end this process.

[0096] Among them, the designated audio file is used to describe the work tasks of the legal workers after entering the smart agricultural greenhouse.

[0097] 307. The Arduino controller determines that the target audio file being played by the wearable device is the designated audio file, and unlocks the smart door.

[0098] 308. The Arduino controller determines the unlocking completion time of the smart door, and estimates the estimated playing time of the target audio file played by the wearable device based on the actual playing time of the target audio file and the unlocking completion time of the smart door.

[0099] 309. The Arduino controller calculates a ratio of the estimated playback time of the target audio file to the total playback time of the designated audio file.

[0100] 310. The Arduino controller determines whether the ratio exceeds a specified target threshold; if so, executes step 311; if not, terminates the process.

[0101] 311. The Arduino controller broadcasts second interactive information including the unique device ID, the unique identifier of the Internet of Things management platform corresponding to the smart agricultural greenhouse, and access verification information of the Internet of Things management platform.

[0102] 312. The wearable device receives the second interaction information and identifies whether the unique device ID is the same as the unique identity ID of the wearable device; if they are the same, execute step 313; if they are not the same, end this process.

[0103] 313. The wearable device accesses the Internet of Things management platform corresponding to the smart agricultural greenhouse according to the unique identifier of the Internet of Things management platform corresponding to the smart agricultural greenhouse and the access verification information of the Internet of Things management platform.

[0104] It should be noted that, in the embodiment of the present application, the designated target threshold can be set according to actual needs, and the embodiment of the present application does not limit it.

[0105] It can be understood that when the specified target threshold is large, the estimated playback time of the target audio file is required to be longer when the wearable device receives the first interactive information in order to increase the probability that the ratio of the estimated playback time of the target audio file to the total playback time of the specified audio file (this is a fixed value) exceeds the specified target threshold. Requiring that the estimated playback time of the target audio file is longer when the wearable device receives the first interactive information means that the user wearing the wearable device is required to listen to the target audio file through the wearable device for a longer time when the wearable device receives the first interactive information, so that the user wearing the wearable device is as clear as possible about his or her work tasks after entering the smart agricultural greenhouse.

[0106] 314. The Arduino controller reports a request for obtaining operation instruction information including the task type of the operation task and the unique device ID to the IoT management platform.

[0107] 315. The wearable device obtains the operation guidance information of the operation task that matches the task type and is issued by the Internet of Things management platform in response to the operation task guidance information acquisition request and according to the unique device ID.

[0108] 316. The wearable device outputs the operation guidance information.

[0109] In an embodiment of the present application, when implementing the above steps 308 to 313, only on the premise that the user wearing the wearable device is as clear as possible about the work tasks after entering the smart agricultural greenhouse, is the wearable device allowed to access the Internet of Things management platform corresponding to the smart agricultural greenhouse to obtain the work guidance information of the work tasks, so as to improve the integrity and correctness of the execution of the work tasks.

[0110] For example, when the task type of the operation task is deep plowing and soil breaking (in this case, the operation task is to perform deep plowing and soil breaking operations on the soil in certain areas to be planted in the smart agricultural greenhouse), the Internet of Things management platform responds to the operation task guidance information acquisition request and matches the operation task with the task type issued according to the unique device ID. The operation guidance information may include a specified deep plowing and soil breaking thickness (such as 50 cm), a setting method for setting the specified deep plowing and soil breaking depth (such as 50 cm) on the deep plowing machine, and a rear door for the user to open the cockpit door of the deep plowing machine. key segment; wherein, the Internet of Things management platform can divide the preset complete opening key corresponding to the cockpit door of the deep tillage machine according to the actual playing time of the target audio file when the wearable device receives the first interactive information, and obtain the front key segment and the back key segment; wherein, the character length of the front key segment is directly proportional to the actual playing time of the target audio file when the wearable device receives the first interactive information, that is, the longer the actual playing time of the target audio file when the wearable device receives the first interactive information, the longer the character length of the front key segment. , accordingly, the character length of the rear key segment is shorter; and, the Internet of Things management platform sends the front key segment to the gate control device of the deep tillage machine for storage, and uses the specified deep tillage thickness (such as 50 cm), the setting method of setting the specified deep tillage depth (such as 50 cm) on the deep tillage machine, and the rear key segment as the operation guidance information of the operation task matching the task type and sends it to the wearable device according to the unique device ID, so that the user can input the rear key segment to the gate control device of the deep tillage machine, and the gate control device of the deep tillage machine The front key segment and the rear key segment are spliced ​​to form a verification key, and the verification key is checked to see if it is the same as the preset complete opening key pre-stored in the door control device. If they are the same, the cockpit door of the deep plowing machine is controlled to open so that the user can enter the cockpit of the deep plowing machine, and the specified deep plowing thickness (such as 50 cm) is set according to the setting method of setting the specified deep plowing depth (such as 50 cm) on the deep plowing machine, so that the deep plowing machine performs deep plowing operations according to the specified deep plowing thickness (such as 50 cm) under the control of the user.

[0111] In an embodiment of the present application, when the wearable device receives the first interactive information, the longer the actual playback time of the target audio file is, the longer the character length of the front key segment is, and correspondingly the character length of the rear key segment is shorter. The shorter the character length of the rear key segment, the higher the efficiency of the user in inputting the rear key segment into the door control device of the deep plowing machine, thereby quickly controlling the opening of the cockpit door of the deep plowing machine, which helps to improve the efficiency of the deep plowing machine in deep plowing operations according to the specified deep plowing thickness (such as 50 cm) under the control of the user.

[0112] In some optional implementations, the user may input the rear key segment into the gate control device of the deep tillage machine in the following manner:

[0113] The Internet of Things management platform sends the connection verification string randomly assigned by the Internet of Things management platform to the door control device of the deep tillage scarifier when the door control device of the deep tillage scarifier was last wirelessly connected to the Internet of Things management platform to the wearable device;

[0114] The wearable device receives the connection verification string and broadcasts a wireless connection request including the connection verification string, a unique identity ID of the wearable device, and an instant location of the wearable device;

[0115] The gate control device of the deep tillage scarifier receives the wireless connection request, and upon recognizing that the gate control device of the deep tillage scarifier has stored the connection verification string included in the wireless connection request, determines a target distance, and determines whether the distance value between the instantaneous position of the wearable device and the instantaneous position of the deep tillage scarifier is less than or equal to the target distance, and if so, establishes a wireless connection with the wearable device;

[0118] When the gate control device of the deep tillage scarifier identifies that the gate control device of the deep tillage scarifier has stored the connection verification string included in the wireless connection request, the gate control device of the deep tillage scarifier determines whether the number of historical connections between the wearable device and the gate control device of the deep tillage scarifier in a set historical period exceeds a specified number of connections based on the unique identity ID of the wearable device; if not, the preset distance is used as the target distance; if exceeded, the difference between the number of historical connections and the specified number of connections is calculated;

[0120] Among them, when implementing the above-mentioned embodiment, when the number of historical connections for establishing a wireless connection between the wearable device and the gate control device of the deep plowing machine within a set historical period exceeds the specified number of connections, the probability of judging that the distance value between the instant position of the wearable device and the instant position of the deep plowing machine is less than or equal to the target distance can be increased, thereby improving the success rate of establishing a wireless connection between the wearable device and the gate control device of the deep plowing machine.

[0121] It can be seen that implementation Figure 3 In the Arduino-based smart door control method for a smart agricultural greenhouse shown in the figure, the smart door is unlocked only when the face of a legitimate operator with an operating task is scanned, thereby reducing the occurrence of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking.

[0129] 414. The wearable device receives the second interaction information and identifies whether the unique device ID is the same as the unique identity ID of the wearable device; if they are the same, execute step 415; if they are not the same, end this process.

[0130] 415. The wearable device accesses the Internet of Things management platform corresponding to the smart agricultural greenhouse according to the unique identifier of the Internet of Things management platform corresponding to the smart agricultural greenhouse and the access verification information of the Internet of Things management platform.

[0131] 416. The Arduino controller reports a request for obtaining operation instruction information including the task type of the operation task and the unique device ID to the IoT management platform.

[0132] 417. The wearable device obtains the operation guidance information of the operation task that matches the task type and is issued by the Internet of Things management platform in response to the operation task guidance information acquisition request and based on the unique device ID.

[0134] In an embodiment of the present application, the Arduino controller reads the recorded number of executions of historical tasks matching the task type that have been performed by the legal operator in the smart agricultural greenhouse, and when it is determined that the number of executions does not exceed the specified number, the Arduino controller may consider that there is a risk that the user may be unfamiliar with the task. Only then is the wearable device allowed to access the Internet of Things management platform corresponding to the smart agricultural greenhouse and obtain the operation guidance information of the task issued by the Internet of Things management platform. This not only improves the completeness and correctness of the user's operation on the task, but also helps to reduce the number of devices connected to the Internet of Things management platform, thereby reducing the workload of the Internet of Things management platform.

[0135] It can be seen that implementation Figure 4In the Arduino-based smart door control method for a smart agricultural greenhouse shown in the figure, the smart door is unlocked only when the face of a legitimate operator with an operating task is scanned, thereby reducing the occurrence of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking.

It is understood that the wearable device 502 can include but is not limited to a smart bracelet, a smart watch, a phone watch, a wrist phone or a headset, and is not limited in this embodiment of the application. Among them:

[0138] The Arduino controller 501 is configured to capture a facial image of the user using a camera module when the user approaches the locked smart door outside the smart agricultural greenhouse;

[0139] The Arduino controller 501 is also used to unlock the smart door when it is recognized that the user is a legal operator preset by the Arduino controller 501 and allowed to enter the smart agricultural greenhouse based on the user's facial image, and if it is recognized that the wearable device 502 is playing a specified audio file; wherein the specified audio file is used to describe the work tasks of the legal operator after entering the smart agricultural greenhouse.

[0144] The Arduino controller 501 receives the first response information and identifies whether the unique audio ID of the target audio file being played by the wearable device 502 is the same as the unique audio ID of the specified audio file associated with the preset unique device ID; if they are the same, it is determined that the target audio file being played by the wearable device 502 is the specified audio file, and the smart door is unlocked.

[0145] In some optional embodiments, Figure 5 The Arduino-based smart door control system for the smart agricultural greenhouse shown also includes an Internet of Things management platform 503 corresponding to the smart agricultural greenhouse, wherein:

[0146] The wearable device 502 is further configured to access the Internet of Things management platform 503 corresponding to the smart agricultural greenhouse after the Arduino controller 501 unlocks the smart door;

[0147] The Arduino controller 501 is further configured to report a request for obtaining operation instruction information including the task type of the operation task and the unique device ID to the Internet of Things management platform 503;

[0148] The wearable device 502 is further configured to obtain the operation instruction information of the operation task matched with the task type issued by the Internet of Things management platform 503 in response to the operation task instruction information acquisition request and according to the unique device ID;

[0149] The wearable device 502 is further configured to output the operation guidance information.

[0150] In some other optional embodiments, Figure 5 In the Arduino-based smart door control system for smart agricultural greenhouses shown in FIG, the first response information also includes the actual playback duration of the target audio file when the wearable device 502 receives the first interactive information. Then:

[0151] The Arduino controller 501 is further configured to, after unlocking the smart door, determine a time point at which the smart door is unlocked, and estimate an estimated playback time length of the target audio file played by the wearable device 502 based on the actual playback time length of the target audio file and the time point at which the smart door is unlocked;

[0152] The Arduino controller 501 is further configured to calculate a ratio of the estimated playback duration of the target audio file to the total playback duration of the designated audio file;

[0153] The Arduino controller 501 is further configured to determine whether the ratio exceeds a specified target threshold; if so, broadcast a second interactive message including the unique device ID, the unique identifier of the IoT management platform 503 corresponding to the smart agricultural greenhouse, and access verification information of the IoT management platform 503;

[0154] The wearable device 502 is connected to the Internet of Things management platform 503 corresponding to the smart agricultural greenhouse in the following manner:

[0155] The wearable device 502 receives the second interactive information and identifies whether the unique device ID is the same as the unique identity ID of the wearable device 502; if they are the same, it accesses the Internet of Things management platform 503 corresponding to the smart agricultural greenhouse based on the unique identifier of the Internet of Things management platform 503 corresponding to the smart agricultural greenhouse and the access verification information of the Internet of Things management platform 503.

[0156] In some other optional embodiments, Figure 5 In the smart door control system of the smart agricultural greenhouse based on Arduino:

[0157] The Arduino controller 501 is further configured to read the number of executions of historical tasks matching the task type that have been recorded by the legal operator in the smart agricultural greenhouse after determining that the ratio exceeds a specified target threshold;

[0158] The Arduino controller 501 is also used to determine whether the execution times exceed the specified times; if not, execute the step of broadcasting the second interactive information including the unique device ID, the unique identifier of the Internet of Things management platform 503 corresponding to the smart agricultural greenhouse and the access verification information of the Internet of Things management platform 503.

[0159] For example, when the task type of the operation task is deep plowing and soil breaking (in this case, the operation task is to perform deep plowing and soil breaking operations on the soil in certain areas to be planted in the smart agricultural greenhouse), the Internet of Things management platform 503 responds to the operation task guidance information acquisition request and matches the operation task with the task type issued according to the unique device ID. The operation guidance information may include a specified deep plowing and soil breaking thickness (such as 50 cm), a setting method for setting the specified deep plowing and soil breaking depth (such as 50 cm) on the deep plowing machine, and a rear seal for the user to open the cockpit door of the deep plowing machine. key segment; wherein, the Internet of Things management platform 503 can divide the preset complete opening key corresponding to the cockpit door of the deep tillage machine according to the actual playing time of the target audio file when the wearable device 502 receives the first interactive information, and obtain the front key segment and the back key segment; wherein, the character length of the front key segment is directly proportional to the actual playing time of the target audio file when the wearable device receives the first interactive information, that is, the longer the actual playing time of the target audio file when the wearable device receives the first interactive information, the longer the character length of the front key segment. The longer the character length of the rear key segment is, the shorter the character length of the rear key segment will be; and the Internet of Things management platform 503 sends the front key segment to the gate control device of the deep tillage tiller for storage, and uses the specified deep tillage thickness (such as 50 cm), the setting method of setting the specified deep tillage depth (such as 50 cm) on the deep tillage tiller, and the rear key segment as the operation guidance information of the operation task matching the task type and sends it to the wearable device 502 according to the unique device ID, so that the user can input the rear key segment to the gate control device of the deep tillage tiller, and the deep tillage tiller The gate control device splices the front key segment and the rear key segment to form a verification key, and verifies whether the verification key is the same as the preset complete opening key pre-stored in the gate control device. If they are the same, the cockpit door of the deep plowing machine is controlled to open so that the user can enter the cockpit of the deep plowing machine, and the specified deep plowing thickness (such as 50 cm) is set according to the setting method of setting the specified deep plowing depth (such as 50 cm) on the deep plowing machine, so that the deep plowing machine performs deep plowing operations according to the specified deep plowing thickness (such as 50 cm) under the control of the user.

[0160] In an embodiment of the present application, when the wearable device 502 receives the first interactive information, the longer the actual playback time of the target audio file is, the longer the character length of the front key segment is, and correspondingly the character length of the rear key segment is shorter. The shorter the character length of the rear key segment, the higher the efficiency of the user in inputting the rear key segment into the door control device of the deep plowing machine, thereby quickly controlling the opening of the cockpit door of the deep plowing machine, which helps to improve the efficiency of the deep plowing machine in deep plowing operations according to the specified deep plowing thickness (such as 50 cm) under the control of the user.

[0161] In some optional implementations, the user may input the rear key segment into the gate control device of the deep tillage machine in the following manner:

[0162] The Internet of Things management platform 503 sends the connection verification string randomly assigned by the Internet of Things management platform 503 to the door control device of the deep tillage scarifier when the door control device of the deep tillage scarifier was last wirelessly connected to the Internet of Things management platform 503 to the wearable device 502;

[0163] The wearable device 502 receives the connection verification string and broadcasts a wireless connection request including the connection verification string, the unique identity ID of the wearable device 502 and the current location of the wearable device 502;

[0164] The gate control device of the deep tillage scarifier receives the wireless connection request, and upon recognizing that the gate control device of the deep tillage scarifier has stored the connection verification string included in the wireless connection request, determines a target distance, and determines whether the distance value between the instantaneous position of the wearable device 502 and the instantaneous position of the deep tillage scarifier is less than or equal to the target distance. If so, establishes a wireless connection with the wearable device 502;

[0165] The wearable device 502 automatically inputs the rear key segment to the gate control device of the deep tillage machine through the wireless connection.

[0166] The gate control device of the deep tillage scarifier determines the target distance when recognizing that the gate control device of the deep tillage scarifier has stored the connection verification string included in the wireless connection request, including:

[0167] When the gate control device of the deep tillage scarifier identifies that the gate control device of the deep tillage scarifier has stored the connection verification string included in the wireless connection request, the gate control device of the deep tillage scarifier determines whether the number of historical connections between the wearable device 502 and the gate control device of the deep tillage scarifier in a set historical period exceeds the specified number of connections according to the unique identity ID of the wearable device 502; if not, the preset distance is used as the target distance; if exceeded, the difference between the number of historical connections and the specified number of connections is calculated;

[0168] The gate control device of the deep tillage scarifier obtains a distance change, which is proportional to the difference in the number of connections; and calculates the sum of the preset distance and the distance change as the target distance.

[0169] Among them, when implementing the above-mentioned embodiment, when the number of historical connections for establishing a wireless connection between the wearable device 502 and the gate control device of the deep plowing machine within a set historical period exceeds the specified number of connections, the probability of judging that the distance value between the instant position of the wearable device and the instant position of the deep plowing machine is less than or equal to the target distance can be increased, thereby improving the success rate of establishing a wireless connection between the wearable device and the gate control device of the deep plowing machine.

[0170] It can be seen that implementation Figure 5 In the Arduino-based smart door control system for smart agricultural greenhouses shown in the figure, the smart door is unlocked only when the face of a legitimate operator with an assignment is scanned, thus reducing the occurrence of pests in the smart agricultural greenhouse caused by unnecessary smart door unlocking.
