[0030] The method embodiments provided in the embodiments of the present invention can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a method for limiting the function of multiple devices according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0031] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the function restriction method of multiple devices in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0032] According to an embodiment of the present invention, a method embodiment of a method for limiting the functions of multiple devices is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] Figure 2 is a flow chart of a method for limiting the functions of multiple devices according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0034] Step S202: the device control server groups multiple devices with the same functions into a device block, so that all devices in the device block establish communication connections.

[0035] It should be noted that the above-mentioned device control server is a central server for managing and controlling multiple devices, which can realize remote monitoring, setting and control of the devices, as well as restriction and management of device functions.

[0036] In this embodiment, multiple devices with the same function are grouped into a device block, which can improve the collaboration and communication efficiency between devices. By establishing a communication connection, the devices in the device block can share data and work together to improve the overall performance and efficiency of the system. At the same time, through the management and control of the device block, the devices in the device block can be managed in a unified manner, which is convenient for centralized control and monitoring, thereby improving the security and stability of the system. The establishment of device blocks can simplify the structure and management of the system, reduce system maintenance costs, and improve the scalability and flexibility of the system.

[0037] Specifically, the device control server organizes multiple devices with the same functions into device blocks. Communication connections are established for the devices in each device block. Each device controller stores a copy of the data of the device relationship block and connects to the network. To achieve batch control, the networking function is used to realize communication between the server and the device, and between the devices in the relationship block. The entire data relationship block will eventually be encrypted into a string and transmitted between devices.

[0038] Optionally, the data of the device relationship block may include, but is not limited to: relationship block name, relationship block update time, device ID, and restricted function list.

[0039] Optionally, the above networking function can be wifi or a 4g / 5g communication module.

[0040] Step S204: the device control server sends a modification restricted function list instruction to the target device, so that the target device modifies the restricted function list of the target device, and other devices receive the first relationship block data sent by the target device, the first relationship block data includes the modified restricted function list and the device block name of the device block to which the target device belongs, and the other devices are the devices other than the target device in the device block; the first relationship block data sent by the target device is compared with the second relationship block data of the other devices to obtain a comparison result, the second relationship block data includes the restricted function list of the other devices and the device block name of the device block to which the other devices belong; when the comparison result is that the device block name of the first relationship block data is the same as the device block of the second relationship block data and the modified restricted function list is different from the restricted function list of the other devices, the restricted function list of the other devices is updated to the modified restricted function list, the target device is any device in the device block, the restricted function list corresponds to the device one-to-one, and the restricted function list includes functions that the device is not allowed to control.

[0041] In this embodiment, by sending a modification instruction of the restricted function list to the target device through the device control server, the functions of all devices in the device block can be centrally managed and controlled. By modifying the restricted function list, certain devices in the device block can be restricted from performing specific functions, thereby ensuring that the devices comply with relevant regulations and safety requirements during use. At the same time, synchronizing the modified restricted function list to all devices in the device block can ensure that all devices comply with the same functional restrictions, avoiding inconsistent functions, thereby improving management efficiency and consistency, and being able to effectively manage multiple devices in the device block, achieve unified control and management, and ensure the safety and compliance of device use.

[0042] It should be noted that the above-mentioned restricted function list is a list of restricted functions that needs to be designed and stored separately for the control inside the device. When receiving external instructions, the system needs to filter through the restricted function list to ensure that the instructions in the restricted function list are not executed, regardless of whether the operation is performed through infrared remote control, APP (Application program) control, etc.

[0043] Optionally, the above restricted function list may be in the form of an array, a list, etc.

[0044] From the above, it can be seen that in the embodiment of the present invention, by forming a device block with multiple devices with the same functions, all devices in the device block establish a communication connection, and the device control server can send a modified restricted function list instruction to the target device, so that the target device modifies its restricted function list, and synchronizes the modified restricted function list to all devices in the device block, thereby realizing function restriction of all devices in the device block and realizing batch control. There is no need to set function restriction for each device one by one, which solves the problem of low efficiency in performing function restriction on multiple devices in the prior art.

[0045] Figure 3 is a flow chart of an optional multi-device function restriction method according to an embodiment of the present invention. Figure 3 As shown, when the target device receives the instruction to modify the restricted function list sent by the server and completes the writing, it spontaneously sends the data of its own device relationship block through broadcast at a certain interval. Other devices receive the broadcast data (i.e., the first relationship block data) and compare it with the stored device relationship block data (i.e., the second relationship block data). When the received broadcast data is the same as the stored device relationship block data, and the restricted function list after writing by the target device is different from the restricted function lists of other devices, the restricted function lists stored in other devices are updated to the restricted function list after writing.

[0046] It should be noted that the above restricted function list only accepts write operations sent by the server and synchronization operations of the relationship block to which the device belongs, that is, functions that are not allowed to operate.

[0047] In addition, it should be noted that broadcast communication is performed between devices so that devices in the same relationship block can be aware of each other's existence, which facilitates sending their own device data and synchronizing the data of other devices (ie, relationship block data).

[0048] In the above embodiment of the present invention, when the comparison result is that the device block name of the first relationship block data is the same as the device block of the second relationship block data and the modified restricted function list is different from the restricted function list of other devices, the process of updating the restricted function list of other devices to the modified restricted function list includes: when the comparison result is that the device block name of the first relationship block data is the same as the device block of the second relationship block data and the update time of the modified restricted function list is later than the update time of the restricted function list of other devices, updating the restricted function list of other devices to the modified restricted function list, the first relationship block data also includes the update time of the modified restricted function list, and the second relationship block data also includes the update time of the restricted function list of other devices.

[0049] In this embodiment, by comparing the update time of the restricted function lists of different devices, the function of updating the restricted function lists of other devices to the modified restricted function list can be realized, which can ensure that the function restrictions on all devices are consistent and avoid inconsistencies. By comparing the update time, it can be ensured that the modified restricted function list is the latest, ensuring the security and stability of the system, improving the management efficiency of the system, reducing the workload of managers, and also providing users with a more stable and unified functional experience.

[0050] like Figure 3 As shown, after receiving the broadcast data, other devices compare whether the relationship block name (i.e., the device block name of the first relationship block data) in the received data is the same as their own relationship block name (i.e., the device block name of the second relationship block data), that is, whether they belong to their own relationship block. If they are not the same, ignore the data. If they are the same, continue to compare whether the update time of the modified restricted function list is greater than the data time saved by themselves. When the device block names are the same and the update time is greater than the data time saved by themselves, update the restricted function lists of other devices to the modified restricted function list. If it is less than the data time saved by themselves, it is saved in a temporary area and not updated temporarily.

[0051] According to the above embodiment of the present invention, the device control server sends an instruction to modify the restricted function list to the target device, so that the target device modifies the restricted function list of the target device, including: the device control server uses a private key to encrypt the instruction to modify the restricted function list to obtain an encrypted instruction; the device control server sends the encrypted instruction to the target device, so that the target device uses the public key corresponding to the private key to decrypt the encrypted instruction to obtain the instruction to modify the restricted function list and modifies the information of the restricted function list of the target device according to the instruction to modify the restricted function list.

[0052] In this embodiment, the communication security between the device control server and the target device can be effectively protected to prevent unauthorized operations from modifying the device function list. By using private key encryption and decryption, the confidentiality of instruction transmission is ensured. Only devices with corresponding private keys can decrypt and execute instructions, thereby effectively controlling the functional limitations of the device. It can also ensure the integrity of the instructions, prevent the instructions from being tampered with or forged during transmission, and ensure the validity and reliability of the instructions.

[0053] It should be noted that the device control server uses a private key to encrypt the instruction to modify the restricted function list, and encrypts the content written into the restricted function list to prevent it from being used by criminals.

[0054] According to the above embodiment of the present invention, after the device control server sends an instruction to modify the restricted function list to the target device, so that the target device modifies the restricted function list of the target device and synchronizes the modified restricted function list to all devices in the device block, the multi-device function restriction method also includes: when the target device receives the control instruction and the restricted function list of the target device contains a function corresponding to the control instruction, the target device does not execute the control instruction.

[0055] In this embodiment, it can be ensured that the target device can be restricted according to its restricted function list when receiving a control instruction, avoiding the execution of control instructions that may cause problems or security risks. The security and reliability of the target device can be improved, the user's privacy and data security can be protected, and it is helpful to uniformly manage the functional restrictions of multiple devices, simplify the management and maintenance processes, and improve the overall efficiency and availability of the system.

[0056] That is, if the control instruction received by the target device is a control instruction for which the operation is not permitted, the target device does not execute the control instruction.

[0057] According to the above embodiment of the present invention, after the device control server groups multiple devices with the same functions into a device block, the function limitation method of multiple devices also includes: the device control server sends a status control instruction to the target device, so that the target device adjusts the device status according to the status control instruction and synchronizes the device status to all devices in the device block, and the device status includes the on / off status of the device.

[0058] In this embodiment, by sending status control instructions to the target device through the device control server, unified control and management of multiple devices can be achieved. By adjusting the device status and synchronizing the device status to the devices of all device blocks, the status synchronization between the various devices can be ensured, thereby improving the collaborative working efficiency of the devices. By sending status control instructions through the device control server, multiple devices can be centrally managed and monitored, thereby improving the management efficiency and operational safety of the devices.

[0059] In addition, the target device continues to receive data broadcast by other devices, and saves them for comparison. When a large number of device IDs are shared in a certain group of saved data, its own relationship block data is updated synchronously, and broadcast outward after the synchronous writing is completed.

[0060] In summary, it can ensure that the data block of the device will not be easily modified, and it will be updated synchronously after other devices are updated, avoiding the situation where devices in the area request the server at the same time, causing load difficulties for the server and base station. It can synchronize device relationship blocks and can also be used to synchronize other information such as device status.

[0061] The technical solution provided by the above embodiment of the present invention solves the problem of batch locking the functions specified by all devices in the same area, not allowing private adjustment, and individual devices being unable to keep consistent with other devices due to too many devices under batch control. At the same time, it has the beneficial effect of improving the processing efficiency of batch control devices, which is conducive to better management of equipment by site managers.

[0062] That is, the technical solution provided by the embodiment of the present invention comprehensively considers various factors, implements the function of batch locking or controlling devices based on the device relationship block, and improves the success rate of batch controlling devices.

[0063] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0064] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, disk, CD), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.

[0065] According to an embodiment of the present invention, a multi-device function restriction apparatus for implementing the multi-device function restriction method is also provided. Figure 4 is a schematic diagram of a function limiting device for multiple devices according to an embodiment of the present invention. Figure 4 As shown, the device includes: a grouping unit 401 and a sending unit 403. The function limiting device for multiple devices is described below.

[0066] The grouping unit 401 is used for the device control server to group multiple devices with the same function into a device block, so that all devices in the device block establish communication connections.
