Description

Technical Field

[0001] This specification relates to the field of computer technology, and in particular to a remote operation and maintenance system, method, and device. Background Art

[0002] In the new retail warehousing sector, various internet-based devices, such as sensors, gateways, and facial recognition attendance machines, are deployed in major warehouses. When problems arise with these devices, maintenance personnel must remotely operate and maintain the equipment because the device is located on a different local area network than the one used by the maintenance personnel.

[0003] In the existing technology, a VPN gateway device can be installed in each warehouse and another VPN gateway device can be installed at the operation and maintenance personnel's end. Based on the two VPN gateway devices, a virtual private network (i.e., virtual local area network) is formed. The operation and maintenance personnel can use the VPN to operate and maintain the equipment with problems.

[0004] However, in the prior art, operation and maintenance of devices with problems through VPN must rely on VPN gateway devices, thereby increasing resource waste during the operation and maintenance process. Summary of the Invention

[0068] To make the objectives, technical solutions, and advantages of this specification more clear, the following will clearly and completely describe the technical solutions of this specification in conjunction with the specific embodiments of this specification and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this specification.

[0069] The technical solutions provided by the embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0070] Taking the warehouse operation and maintenance scenario as an example, in the warehousing field, various equipment needs to be deployed in each warehouse. When the equipment in the warehouse fails, the operation and maintenance personnel will choose to remotely operate and maintain various equipment in the warehouse in order to improve operation and maintenance efficiency.

[0071] In the embodiments of this specification, the business in the warehouse can be processed through the communication link between the device in the warehouse and the first device (which can be a business server), so each device in the warehouse needs to establish a long connection with the first device, that is, each device in the warehouse needs to maintain communication with the first device. Under the condition that each device in the warehouse establishes a long connection with the first device, the first device can monitor the status of each device in the warehouse in real time, that is, monitor whether each device in the warehouse has a fault. When a device in the warehouse fails, the operation and maintenance personnel can promptly operate and maintain the faulty device through the remote operation and maintenance system. It should be noted that the first device does not refer to a fixed hardware device. Different software can be run on the first device according to actual needs, and the first device implements different functions according to different software.

[0072] Figure 1 This is a schematic diagram of the remote operation and maintenance system structure provided in an embodiment of this specification. The remote operation and maintenance system includes: a device to be operated and maintained, a first device, a second device, and an operation and maintenance device. The device to be operated and maintained is located in a warehouse's local area network, while the first device, the second device, and the operation and maintenance device are located in the local area network where the operation and maintenance personnel reside. That is, the first device, the second device, and the operation and maintenance device are all in the same local area network. Furthermore, the device to be operated and maintained is connected to the first device, and the device to be operated and maintained is connected to the second device via the public network.

[0073] In an embodiment of the present specification, the device to be operated and maintained first establishes a long connection with the first device. On this basis, the first device receives the operation and maintenance start-up instruction sent by the operation and maintenance operation device, and sends the operation and maintenance start-up instruction to the device to be operated and maintained based on the long connection. After receiving the operation and maintenance start-up instruction sent by the first device, the device to be operated and maintained sends its own first address information to the second device. After receiving the first address information of the device to be operated and maintained, the second device establishes a mapping relationship between the first address information and its own second address information based on the first address information. When the second device receives the operation and maintenance operation instruction sent by the operation and maintenance operation device, it sends the operation and maintenance operation instruction to the device to be operated and maintained based on the mapping relationship. Among them, the destination address information in the operation and maintenance operation instruction is the second address information of the second device. The device to be operated and maintained performs the operation and maintenance operation according to the received operation and maintenance operation instruction.

[0074] In the embodiments of this specification, Message Queuing Telemetry Transport (MQTT) client software and reverse proxy service client software can be installed on the device to be operated and maintained. The MQTT server software is installed on the first device, the reverse proxy service server software is installed on the second device, and the operation and maintenance service software and operation and maintenance tool software are installed on the operation and maintenance operation device, wherein the operation and maintenance tool software includes but is not limited to ssh, adb, etc. Then, each device performs remote operation and maintenance through each software. Since each device in the remote operation and maintenance system performs remote operation and maintenance through the installed software, the first device, the second device and the operation and maintenance operation device can be the same hardware device. That is to say, the first device, the second device and the operation and maintenance operation device can be in the same local area network. Among them, the first device, the second device and the operation and maintenance operation device can be servers. The device to be operated and maintained can be a device that requires operation and maintenance due to a fault, such as: a sensor, a gateway device, a camera, a face attendance machine, etc.

[0075] It should be noted that the remote operation and maintenance system in this manual can be applied to any operation and maintenance scenario.

[0076] Among them, the prerequisite for operating and maintaining the equipment to be operated and maintained that has failed in the warehouse is that the equipment to be operated and maintained establishes a long connection with the first device. The process of establishing a long connection is: after the equipment to be operated and maintained is powered on, the equipment to be operated and maintained sends a connection instruction to the first device based on the public network through the MQTT client software installed on the equipment to be operated and maintained. The first device receives the connection instruction through the MQTT server software and establishes an MQTT long connection with the equipment to be operated and maintained according to the connection instruction. That is, the equipment to be operated and maintained establishes an MQTT long connection with the first device through the public network. It should be noted that the long connection between the equipment to be operated and maintained and the first device is not limited to MQTT, as long as a long connection is established between the equipment to be operated and maintained and the first device.

[0077] After the device to be operated and maintained establishes a persistent connection with the first device, the operation and maintenance device sends an operation and maintenance start-up instruction to the first device via the operation and maintenance service software installed on the operation and maintenance device. The first device receives the operation and maintenance start-up instruction via the MQTT server software installed on the first device and sends the operation and maintenance start-up instruction to the device to be operated and maintained via the MQTT server software. The operation and maintenance start-up instruction includes the second address information of the specified second device. The device to be operated and maintained receives the operation and maintenance start-up instruction via the MQTT client software and sends the operation and maintenance start-up instruction to the reverse proxy service client software installed on the device to be operated and maintained. The reverse proxy service client software starts the reverse proxy service client software based on the received operation and maintenance start-up instruction. Then, based on the second address information of the second device contained in the operation and maintenance start-up instruction, the device to be operated and maintained sends a reverse proxy service connection request to the reverse proxy service server software installed on the second device via the reverse proxy service client software over the public network. The reverse proxy service connection request carries the first address information of the device to be operated and maintained. That is, the device to be operated and maintained sends its own first address information to the second device. The second device receives the reverse proxy service connection request through the reverse proxy service server software and establishes a reverse proxy service connection between the reverse proxy service client software and the reverse proxy service server software. After the device to be operated and maintained establishes a reverse proxy service connection with the second device, the second device receives the first address information of the device to be operated and maintained, and establishes a mapping relationship between the first address information and the second address information of the second device itself based on the first address information. In other words, the second device can proxy the service port on the device to be operated and maintained through the reverse proxy service server software. That is, each service port of the device to be operated and maintained is mapped to the service port corresponding to the second device. In this way, for the operation and maintenance device, the second device is the device to be operated and maintained, and the operation and maintenance device can operate and maintain the device to be operated and maintained on the second device.

[0078] After establishing a mapping relationship between the first address information and the second address information, the operation and maintenance device, using the operation and maintenance tool software installed on the operation and maintenance device, sends an operation and maintenance instruction to the second device based on the second device's second address information. The destination address information in the operation and maintenance instruction is the second device's second address information. The second device, using the reverse proxy service server software, maps the second device's second address information to the first address information of the device to be operated and maintained based on the mapping relationship. Then, based on the first address information, the second device transmits the operation and maintenance instruction sent by the operation and maintenance device to the device to be operated and maintained over the public network. After receiving the operation and maintenance instruction, the device to be operated and maintained performs the operation and maintenance operation in accordance with the instruction.

[0079] After the maintenance of the device to be maintained is complete, the maintenance operation device sends a shutdown instruction to the first device via its installed maintenance service software. After receiving the shutdown instruction, the first device sends it to the device to be maintained. The device to be maintained receives the shutdown instruction via the reverse proxy service client software and shuts down the reverse proxy service.

[0080] Based on the above remote operation and maintenance process, this manual provides a cloud architecture, such as Figure 2 shown.

[0081] exist Figure 2 In this example, a device to be operated and maintained is located in LAN 1, and the reverse proxy service client software and MQTT client software are installed on the device to be operated and maintained. The first device, the second device, and the operation and maintenance device are located in LAN 2. LAN 1 and LAN 2 are connected via the public network. MQTT server software is installed on the first device, reverse proxy service server software is installed on the second device, and operation and maintenance service software and operation and maintenance tool software are installed on the operation and maintenance device. The communication interaction between the devices is as follows: Figure 2 shown.

[0082] Taking the camera as an example, when the camera freezes while capturing images, that is, there are missing frames in the captured images, the operation and maintenance personnel can send an operation and maintenance start instruction to the first device through the operation and maintenance operation device. The first device sends the operation and maintenance start instruction to the camera. After the camera receives the operation and maintenance start instruction, it starts the reverse proxy service client software and establishes a connection between the reverse proxy service client software installed on the camera and the reverse proxy service server software installed on the second device. After the camera establishes a connection with the second device, the camera maps the service port to the second device, and the operation and maintenance operation device sends a restart instruction (that is, an operation and maintenance operation instruction) to the second device. The second device sends a restart instruction to the camera. After the camera receives the restart instruction, it automatically restarts. That is, the operation and maintenance is completed.

[0083] Through the above Figure 1It can be seen from the method shown that, in this specification, under the condition that there is a long connection between the device to be operated and maintained and the first device, the operation and maintenance operation device first sends an operation and maintenance start instruction to the first device. The first device sends the received operation and maintenance start instruction to the device to be operated and maintained. After receiving the operation and maintenance start instruction, the device to be operated and maintained sends the first address information of the device to be operated and maintained to the second device. The second device establishes a mapping relationship between the first address information and the second address information of the second device itself based on the received first address information. The operation and maintenance operation device sends the operation and maintenance operation instruction to the second device, and the second device sends the operation and maintenance operation instruction to the device to be operated and maintained based on the mapping relationship. Among them, the destination information in the operation and maintenance operation instruction is the second address information. The device to be operated and maintained performs the operation and maintenance operation according to the operation and maintenance operation instruction. During the whole process, there is no need to set up a gateway device separately, and operation and maintenance are performed according to the software installed on each device, thereby reducing resource waste during the operation and maintenance process.

[0084] Based on the remote operation and maintenance system provided above, and according to each device end in the remote operation and maintenance system, this specification provides a remote operation and maintenance method for each device end.

[0085] Figure 3 This is a flowchart of a remote operation and maintenance method provided in an embodiment of this specification.

[0088] In this embodiment of the present specification, after the device to be operated and maintained establishes a persistent connection with a first device, the operation and maintenance device sends an operation and maintenance start instruction to the first device. After the first device receives the operation and maintenance start instruction, the first device sends the operation and maintenance start instruction to the device to be operated and maintained based on the persistent connection. The device to be operated and maintained receives the operation and maintenance start instruction sent by the first device.

[0089] S304: According to the operation and maintenance start instruction, the first address information of the device to be operated and maintained is sent to the second device, so that the second device establishes a mapping relationship between the second address information of the second device and the first address information according to the first address information.

[0091] In the embodiments of this specification, after determining a mapping relationship between the first address information of the device to be operated and maintained and the second address information of the second device, the operation and maintenance device sends an operation and maintenance instruction to the second device based on the second address information of the second device. After receiving the operation and maintenance instruction, the second device determines the first address information corresponding to the second address information based on the mapping relationship, and sends the operation and maintenance instruction to the device to be operated and maintained via the public network based on the first address information.

After the device to be operated and maintained receives the operation and maintenance start instruction, it sends a reverse proxy service connection request to the second device according to the second address information of the specified second device contained in the operation and maintenance start instruction, wherein the reverse proxy service connection request contains the first address information of the device to be operated and maintained. That is, the device to be operated and maintained sends its own first address information to the second device.

The destination address information in the operation and maintenance instruction is the second address information of the second device. After receiving the operation and maintenance instruction, the second device searches for the first address information corresponding to the second address information based on the mapping relationship.

The device to be operated and maintained performs the operation and maintenance operation according to the operation and maintenance instruction.

[0122] This specification also provides a computer-readable storage medium, wherein the storage medium stores a computer program, which can be used to perform the above-mentioned Figure 3 、 4 , 5, and 6 provide remote operation and maintenance methods.

[0123] based on Figure 3 、 4 , 5, 6 shown in the remote operation and maintenance method, the embodiment of this specification also provides Figure 11 The structural diagram of unmanned equipment is shown in FIG. Figure 11 At the hardware level, the unmanned equipment includes a processor, an internal bus, a network interface, a memory, and a non-volatile memory.

The processor reads the corresponding computer program from the non-volatile memory into the memory and then runs it to achieve the above Figure 3 、 4 , 5, and 6. The remote operation and maintenance method described in

[0124] Of course, in addition to software implementation, this specification does not exclude other implementation methods, such as logic devices or a combination of software and hardware, etc. That is to say, the execution subject of the following processing flow is not limited to each logic unit, but can also be hardware or logic devices.

[0125] In the 1990s, technological improvements could be clearly distinguished as either hardware improvements (for example, improvements to circuit structures like diodes, transistors, and switches) or software improvements (improvements to process flows). However, with the advancement of technology, many process flow improvements today can now be considered direct improvements to hardware circuit structures. Designers almost always create the corresponding hardware circuit structure by programming the improved process flow into the hardware circuit. Therefore, it cannot be said that a process flow improvement cannot be implemented using hardware modules. For example, a programmable logic device (PLD), such as a field programmable gate array (FPGA), is an integrated circuit whose logical function is determined by user programming. Designers can "integrate" a digital system on a PLD through their own programming, without having to hire a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly done using "logic compiler" software. This is similar to the software compiler used when developing programs. Before compilation, the original code must also be written in a specific programming language, called a hardware description language (HDL). There is not just one HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art will also understand that by simply programming the method flow in one of these hardware description languages ​​and then programming it into an integrated circuit, a hardware circuit that implements the logic method flow can be easily obtained.

[0126] The controller can be implemented in any suitable manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to implementing the controller in a purely computer-readable program code format, the controller can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be considered as structures within the hardware component. Or even, the devices for implementing various functions can be considered as both software modules that implement the method and structures within the hardware component.

[0127] The systems, devices, modules, or units described in the above embodiments may be implemented by computer chips or entities, or by products having certain functions. A typical implementation device is a computer. Specifically, the computer may be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
