Data can also be transmitted through the Internet.

In one embodiment, the networked control box 11 and the drive control module 101 are respectively installed in different devices. In addition, the communication device of the networked control box 11 is wired or wirelessly connected to the drive control module 101. It can send operation instructions to the drive control module 101 for execution to perform operation control on the electric device 10 or send inspection instructions to the drive control module 101 for execution to obtain the internal state of the electric device 10. Therefore, the user only needs to purchase a networked control box 11 so that the conventional electric device 10 can have functions such as networking and smart processing (such as an electronic key function described later), and the upgrade cost can be greatly reduced.

In one embodiment, the networked control box 11 and the drive control module 101 are integrated in the same device (ie, the electric device 10 is an electric device with networking and smart processing functions), which can greatly reduce the device volume.

The client application 120 (e.g., an application paired with the networked control box 11) is stored on the user's mobile device 12 (e.g., a smartphone, tablet, wearable device, or other mobile device with a network function) held by the user ) Storage device (not shown in the figure, such as non-transitory computer-readable media), and recorded computer-readable code. After being executed, the client-side application 120 can control the user's mobile device 12 to obtain the original key of the electric device 10 (that is, an electronic key, such as identifiable data such as a specific character sequence or personal biometric information), and via The original key controls the networked control box 11, thereby achieving control of the electric device 10.

In one embodiment, after the aforementioned client application 120 is executed, the client application 120 can also control the client application 120 to interact with other devices (such as the maintenance host 13 or the security server 14 described later) to implement the embodiments of the present invention. Steps of the remote detection method.

Please refer to FIG. 2 together, which is a flowchart of a remote detection method according to the first embodiment of the present invention. The invention proposes an electronic key sharing mechanism, which allows users to conveniently and securely share existing original keys to other users without the need for additional original keys. The present invention also provides a remote detection function based on the aforementioned electronic key sharing mechanism, which can be used by remote maintenance personnel to perform instant detection on the local electric device 10.

In the present invention, when the electric device 10 is faulty or needs to be routinely tested, the user may operate the user mobile device 12 to issue an instant detection application to the maintenance host 13 via the Internet, or, Users can apply for instant detection via customer service via phone or online booking. Then, after receiving the instant detection application, the remote maintenance personnel can operate the maintenance host 13 to perform instant detection on the electric equipment 10.

Specifically, when real-time detection is desired, the user may first operate the user mobile device 12 so that the user mobile device 12 obtains an original key that can be used to control the electric device 10 and performs a preset operation on the obtained original key. The algorithm is encrypted to calculate the shared key (step S10).

It is worth mentioning that the aforementioned client application 120 can record code useful for implementing the aforementioned encryption algorithm, and the user's mobile device 12 can execute the aforementioned code to achieve encryption of the original key.

Then, the user mobile device 12 can obtain the connection information (such as a network address) of the network control box 11 and send the shared key and connection information to the maintenance host 13 via the Internet (step S11).

Then, the maintenance host 13 can connect to the network control box 11 via the Internet according to the received connection information (step S12), such as establishing a P2P connection.

Moreover, the maintenance host 13 may perform a decryption algorithm on the received shared key to calculate a decryption key (step S13). The executed decryption algorithm corresponds to the aforementioned encryption algorithm, that is, the original key before encryption and the decryption key after decryption will match. In one embodiment, the encryption algorithm and the decryption algorithm may use symmetric encryption technology.

It is worth mentioning that the maintenance host 13 can store the maintenance application 130, and the maintenance application 130 can record the code useful for implementing the decryption algorithm, and the maintenance host 13 can execute the foregoing code to achieve the shared key Decryption.

Then, the maintenance host 13 can generate (such as automatically generated or generated by the maintenance personnel's operation) a set of operating instructions (such as a door opening instruction, a door closing instruction, a raising instruction, or a lowering instruction), and decrypt the operating instruction and the decryption through the established connection The key is transmitted to the network control box 11 (step S14).

Then, the network control box 11 can verify the received decryption key (step S15), such as comparing whether the received decryption key matches the pre-stored original key.

If the networked control box 11 determines that the received decryption key is verified, it can execute the received operation instruction to control the electric device 10 to be turned on or off (step S16).

In an embodiment, if the networked control box 11 receives the setting instruction, the received setting instruction may be executed to modify the settings of the electric device 10 or the networked control box 11.

In addition, during the operation of the electric device 10, the built-in sensor 100 senses the internal state of the electric device 10, and the networked control box 11 can obtain the internal state sensed by the built-in sensor 100 and pass the internal state through the Internet. The route is transmitted back to the maintenance host 13 (step S17).

Thereby, the remote maintenance personnel can perform real-time detection by remotely controlling the electric device 10, and can determine whether the electric device 10 is faulty by analyzing the internal state of the electric device 10 and further understand the cause of the fault when determining the fault.

If the network control box 11 determines in step S15 that the received decryption key has not been verified, it can send a warning notification to the user mobile device 12 via the Internet (step S18).

The invention can effectively provide a convenient and safe electronic key sharing mechanism, and can effectively realize remote detection of the electric device 10.

It is worth mentioning that although the electronic key sharing mechanism is applied to the maintenance host 13 operated by the maintenance personnel in the above embodiment, it is not limited thereto.

The electronic key sharing mechanism can also be applied in other situations. Taking the sharing of the electronic key to the tenant as an example, the user mobile device 12 may transmit the generated sharing key to the tenant mobile device held by the tenant, and the tenant mobile device may be installed with a tenant terminal that is the same as or similar to the maintenance application 130 Application, and can decrypt the received shared key to obtain the decryption key, and send the decryption key and the operation instruction (such as the door open instruction) to the networked control box 11 to pass the verification to the electric device 10 Perform control (such as turning on the electric device 10).

Continue to refer to FIG. 3A and FIG. 3B together. FIG. 3A is a first part flowchart of the remote detection method according to the second embodiment of the present invention, and FIG. 3B is a second part flowchart of the remote detection method according to the second embodiment of the present invention. Illustration. Compared to the embodiment of FIG. 2, the electronic key sharing mechanism of the embodiments of FIGS. 3A and 3B can encrypt the same original key to generate different shared keys according to different sharing conditions. In other words, different shareees (such as tenants or maintenance personnel) have different sharing keys due to different sharing conditions (such as tenants' sharing conditions are three days to open the door and maintenance personnel's sharing conditions are to open the door once). It is also different, which makes it easy for users to manage or clarify the ownership of responsibilities when the shared key is outflowed.

In addition, in this embodiment, the original key includes a set of original identification codes and a set of original authorization codes. The original identification code is unique and recognizable and can be used to verify the user's identity, and the original authorization code is used to judge the user's permissions. For example, if the user authority is administrator, not only the electric device 10 can be turned on and off, but also the settings of the electric device 10 or the network control box 11 can be modified; if the user authority is ordinary users, only the power on and off The electric device 10 is turned off without allowing the setting to be modified.

In addition, in this embodiment, the network control system 1 includes a security server 14 connected to the Internet. The security server 14 is used to store the sharing conditions required for encryption and decryption (described in detail later). In one embodiment, the security server 14 is independently provided outside the networked control box 11, the user mobile device 12, and the maintenance host 13, and is managed by different personnel (such as a third-party server), which can greatly reduce the number of users Or maintenance personnel to steal or tamper with data and increase information security.

The following description will take the sharing of an electronic key to remote maintenance personnel for remote detection as an example, but those with ordinary knowledge in the technical field to which the present invention pertains should understand that the electronic key sharing mechanism of this embodiment can also be used in other situations. (Such as sharing electronic keys to tenants).

In this embodiment, when the electronic key is to be shared, the user may first operate the user mobile device 12 to enter a sharing operation to set sharing conditions (step S200). For example, the sharing condition can be a specified period of validity (such as March 16, 2018) or a specified number of valid periods (such as 3 times).

Next, the user mobile device 12 executes an encryption algorithm on the original key according to the set sharing condition to calculate a sharing key corresponding to the sharing condition (step S201).

In an embodiment, the user mobile device 12 may first encode the sharing conditions into a corresponding set of character sequences, and then perform an encryption algorithm on the original key according to the encoded sharing conditions to generate a corresponding set of sharing keys. . The foregoing encryption of the original key to different shared keys based on different character sequences is a common technique in cryptography, and is not repeated here.

Then, the user mobile device 12 can obtain the connection information (such as the network address) of the network control box 11, and send the shared key and connection information to the maintenance host 13 via the Internet (step S202), and via the Internet The sharing key and sharing conditions are transmitted to the security server 14 (step S203).

In an embodiment, after receiving the sharing key and sharing condition, the security server 14 first records the received sharing key and sharing condition in a lookup table, and the foregoing lookup indicates that each time a record is received The correspondence between sharing keys and sharing conditions.

Then, the maintenance host 13 can connect to the network control box 11 via the Internet according to the received connection information (step S204), and query the corresponding sharing conditions from the security server 14 according to the received sharing key (step S205). ). In one embodiment, the maintenance host 13 searches the lookup table of the security server 14 according to the shared key to obtain the corresponding sharing conditions.

After obtaining the sharing conditions, the maintenance host 13 may perform a decryption algorithm on the received shared key to calculate a decryption key (step S206). Then, the maintenance host 13 can generate an instruction (operation instruction or setting instruction), and send the instruction and decryption key to the network control box 11 (step S207).

Then, the network control box 11 can parse the received decryption key to obtain a set of decryption identification code and a set of decryption authorization code, and obtain the pre-stored original key and sharing conditions (the sharing conditions can also be from the security servo Device 14 query).

The network control box 11 determines whether the decryption identification code of the decryption key matches the original identification code of the original key to determine whether the maintenance host 13 has passed the verification (step S208).

In addition, the network control box 11 can also determine whether the sharing conditions are satisfied (step S209), that is, determine whether the sharing conditions are invalid (such as whether the current time exceeds the valid period or whether the number of times the shared key is used exceeds the valid number).

In addition, the networked control box 11 can also determine the authority of the maintenance host 13 according to the decryption authority code, and determine whether the maintenance host 13 has the authority to execute the received instruction (such as the operation instruction or the setting instruction) according to the determined authority (steps) S210).

If the networked control box 11 determines that the maintenance host 13 has passed the verification and sharing conditions (that is, it has not expired) and the maintenance host 13 has the authority to execute the instructions, the received instructions are executed (step S211, such as a running instruction or a setting instruction) .

In addition, during the operation of the electric device 10, the built-in sensor 100 senses the internal state of the electric device 10, and the networked control box 11 can obtain the internal state sensed by the built-in sensor 100 and pass the internal state through the Internet. The route is transmitted back to the maintenance host 13 (step S212).

If the network control box 11 determines in steps S208-S210 that the received decryption key has not been verified, the sharing conditions are not met (that is, it has expired), or the maintenance host 13 does not have the authority to execute the instruction, it can go through the Internet An alert notification is sent to the user mobile device 12 (step S213).

The invention can encrypt the same original key according to different sharing conditions to generate different shared keys, which can facilitate user management.

Please refer to FIG. 2 and FIG. 4 together. FIG. 4 is a partial flowchart of a remote detection method according to a third embodiment of the present invention.

Compared to the embodiment shown in FIG. 2, the remote detection method in the embodiment in FIG. 4 may further perform the following steps after step S16.

Step S30: The maintenance host 13 obtains the operation record of the electric equipment 10. Specifically, the networked control box 11 can usually save the operating state (such as the internal state) of the electric device 10 as an operating record, and store the operating record in a local storage device or upload it to a cloud server via the Internet 15. In this way, the maintenance host 13 can obtain the normal operation records of the electric equipment 10 from the networked control box 11 or the cloud server 15 for reference by maintenance personnel. Furthermore, the maintenance host 13 may output the obtained operation records (such as displayed on a display or listed on a printer).

Step S31: The user mobile device 12 senses an external operating state (hereinafter referred to as an external state) of the electric device 10. Specifically, the user mobile device 12 includes a motion sensor 121. The maintenance personnel may further request the user to provide an external status after viewing the operation record (for example, the maintenance host 13 is operated to send an external status acquisition request to the user mobile device 12). Then, after receiving the external status acquisition request, the user can operate the motion sensor 121 to sense the external status of the electric device 10 and provide it to a remote maintenance person as a detection reference.

Step S31: The user mobile device 12 transmits the sensed external state to the maintenance host 13 via the Internet.

The present invention senses the external state of the electric device 10 through the existing motion sensor 121 of the user's mobile device 12, and can provide more status information of the electric device 10 to maintenance personnel for analysis, and does not need to be provided for sensing A sensor for measuring an external state of the electric device 10.

Please refer to FIG. 8, which is a schematic diagram of remote detection according to an embodiment of the present invention. FIG. 8 illustrates how to obtain the external state by using the electric door 20 as an example.

The aforementioned motion sensor may be a camera, a three-axis accelerometer, or a microphone of the user's mobile device 22 in this example. When the motion sensor is a video camera, the user can operate the user's mobile device 22 to capture a running video of the electric door 20. When the motion sensor is a three-axis accelerometer or a microphone, the user can temporarily fix the user's mobile device 22 on the electric door 20 (as shown by the user's mobile device 22 ') to sense the operation of the electric door 20 via the three-axis accelerometer. The vibration amplitude at the time or the operating sound of the electric door 20 is recorded through a microphone, or the user can temporarily fix the user mobile device 22 on the drive control module of the electric door 20 (such as the position shown by the user mobile device 22 '' in the present In the example, the drive control module 201 is a door opener. The motor, the built-in sensor 200 and the drive control module 201 are integrated and provided in the same casing) to sense the vibration amplitude of the motor via a triaxial accelerometer or record the operating sound of the motor via a microphone.

Please refer to FIG. 9, which is a schematic diagram of remote detection according to another embodiment of the present invention. In FIG. 9, an electric table 30 is used as an example to describe how to obtain an external state.

The aforementioned motion sensor may be a camera, a three-axis accelerometer, or a microphone of the user's mobile device 32 in this example. When the motion sensor is a video camera, the user can operate the user's mobile device 32 to capture a running video of the electric table 30. When the motion sensor is a three-axis accelerometer or a microphone, the user can temporarily place the user's mobile device 32 on the electric table 30 (as shown by the user's mobile device 32 ') to sense the operation of the electric table 30 via the three-axis accelerometer. The vibration amplitude at the time or the operating sound of the electric table 30 is recorded via a microphone, or the user can temporarily fix the user mobile device 32 on the drive control module of the electric table 30 (such as the position shown by the user mobile device 32 '' in the present In the example, the motor, the built-in sensor 300 and the drive control module 301 are integrated in the same housing, and the networked control box 31 is built in the electric table 30) to sense the vibration amplitude of the motor through a three-axis accelerometer Or record the running sound of the motor through the microphone.

Continuing, please refer to FIG. 5, which is a flowchart of automatic updating and abnormal monitoring according to a fourth embodiment of the present invention. The invention further provides a cloud backup function and an abnormality monitoring function for operation records.

Specifically, the networked control box 11 can determine whether the electric device 10 has received the operation instruction (step S40), continuously detects when it is determined that the operation instruction has not been received, and further determines a preset notification when it is determined that the operation instruction has been received. Whether the conditions are satisfied (step S41). If the network control box 11 judges that the notification conditions are met (for example, the current time is the user's time away from home or the frequency of receiving operation instructions is not too high, such as not receiving more than 2 times in 1 minute), it sends an operation notification to the user for action Device 12 (step S42). Otherwise, the networked control box 11 does not issue a notification. Thereby, the present invention can automatically prompt a remote user when the electric device 10 is operated.

In one embodiment, the networked control box 11 sends an operation notification to the cloud server 15 so that the cloud server 15 forwards the operation notification to the user mobile device 12.

Next, the electric device 10 is operated according to the operation instruction, and at the same time, the built-in sensor 100 senses the internal state of the electric device 10 (step S43). After the operation is completed, the network control box 11 can obtain the internal state sensed by the built-in sensor 100 and make a running record (step S44). In one embodiment, the networked control box 11 can further make the received instructions (including the operation instruction, the inspection instruction and the setting instruction) into an operation record.

Next, the network control box 11 determines whether a preset update condition (such as every 100 operation records or 8 am every day) is satisfied (step S45). If the update conditions are met, the operation records that have not been updated to the cloud server 15 are uploaded to the cloud server 15 for cloud backup (step S46). Thereby, the present invention can automatically update the operation records of the electric equipment 10 stored in the cloud server 15.

In one embodiment, the networked control box 11 may delete the operation records stored in the local storage device after uploading the operation records to the cloud server 15 to increase the available storage capacity.

Then, the cloud server 15 can actively analyze the received operation records (such as comparing with the past operation records) to determine whether the operation records are abnormal (step S47), and determine whether the operation records are abnormal (such as the current of the motor). When an abnormality occurs), an abnormality notification is sent to the user mobile device 12 via the Internet (step S48). Accordingly, the present invention can automatically detect whether the electric device 10 is abnormal.

In an embodiment, the cloud server 15 may establish an analysis model based on the past operation records of the electric device 10, and determine whether the current operation records are abnormal according to the established analysis model (such as using machine learning technology or neural network-like). technology).

Continuing, please refer to FIG. 6, which is a flowchart of a maintenance prompt according to a fifth embodiment of the present invention. The invention further provides a maintenance prompt function.

Specifically, the cloud server 15 stores a maintenance record of the electric device 10. The cloud server 15 can determine whether the preset maintenance conditions (e.g., the electric device 10 has been operated 1000 times or the previous maintenance date is more than one year from the previous date) according to the current time, the maintenance record and / or operation record of the electric device 10 (step S50) . If the maintenance conditions are not met, continue to judge. If the maintenance conditions are met, the cloud server 15 sends a maintenance reminder notification to the user mobile device 12 via the Internet to prompt the user to perform maintenance on the electric device 10 (step S51).

Please refer to FIG. 7 for a flowchart of remote setting according to a sixth embodiment of the present invention. The invention further provides a remote setting function, which can be used by maintenance personnel to set the electric device 10 at a remote location.

Specifically, the maintenance personnel can operate the maintenance host 13 to obtain the equipment state of the electric equipment 10 from the cloud server 15 or the networked control box 11 (step S60, such as the values of various setting parameters of the electric equipment 10 and the firmware of the electric equipment 10). Version or operation record of the electric device 10). Next, the maintenance host 13 accepts the setting operation from the maintenance personnel (step S61, such as inputting a parameter value or selecting a firmware version), generates a setting instruction according to the setting operation, and sets the setting instruction and the verification data (such as the aforementioned decryption key and network control) The identification information of the box 11 or the verification code set by the user) is transmitted to the network control box 11 (step S62).

Next, the network control box 11 determines whether the received verification data passes the verification (step S63, such as comparing whether the original key matches the decryption key, or determining whether the received identification information or verification code is correct).

If the network control box 11 determines that the verification data passes the verification, it executes the received setting instruction (step S64). Taking the setting instruction as a firmware update instruction as an example, the networked control box 11 can update the firmware of the electric device 10 or update the firmware of the networked control box 11 to the specified version or the latest version.
