The monitoring equipment will also send control instructions to the on-site terminal to control the working status of the on-site terminal. Among them, the on-site terminal includes power production equipment, power emergency equipment and personal wearable devices. The power production equipment includes sensors, automation equipment and detection instruments, etc. The power emergency equipment includes drones, repair vehicles and control balls, etc. Personal wearable devices include tablets, AR smart glasses and walkie-talkies. Different types of equipment often use different network protocols. Therefore, protocol conversion is required when data is communicated between the monitoring equipment and the on-site terminal.

[0003] In the power emergency repair scenario, the type and number of equipment at the on-site terminal may change at any time, and there is a great deal of uncertainty. For example, during the emergency repair process, a new drone was suddenly added. For another example, during the emergency repair process, the number of control balls increased from one to two. However, the existing heterogeneous network protocol processing system uses gateways or similar devices to achieve protocol conversion, which has low scalability and is difficult to apply to scenarios where the type and number of equipment are prone to change; and because there are many network protocols involved, the existing heterogeneous network protocol processing system also has the problem of a large maintenance workload for protocol conversion.

[0010] Optionally, the server is an edge server.

[0011] Optionally, in the data access terminal, when the interface module accesses a first target on-site terminal, the second data sending module generates a target request according to a target network protocol adopted by the first target on-site terminal;

[0012] The second data sending module sends the target request to the first data receiving module, so that the server obtains the second target protocol decapsulation algorithm and the second target protocol encapsulation algorithm corresponding to the target network protocol from the protocol storage module, and sends the second target protocol decapsulation algorithm and the second target protocol encapsulation algorithm to the second data receiving module through the first data sending module;

[0024] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0025] At present, in the scenario of power emergency repair, it is necessary to realize data communication between the monitoring equipment at the command center and the on-site terminal. Specifically, the on-site data collected by the on-site terminal will be displayed in the monitoring equipment so that the command personnel can read the on-site equipment. The monitoring equipment will also send control instructions to the on-site terminal to control the working status of the on-site terminal. Among them, the on-site terminal includes power production equipment, power emergency equipment and personal wearable devices. The power production equipment includes sensors, automation equipment and detection instruments, etc. The power emergency equipment includes drones, repair vehicles and control balls, etc. Personal wearable devices include tablets, AR smart glasses and walkie-talkies. Different types of equipment often use different network protocols. Therefore, protocol conversion is required when data is communicated between the monitoring equipment and the on-site terminal.

[0026] In the power emergency repair scenario, the type and number of equipment at the on-site terminal may change at any time, and there is a great deal of uncertainty. For example, during the emergency repair process, a new drone was suddenly added. For another example, during the emergency repair process, the number of control balls increased from one to two. However, the existing heterogeneous network protocol processing system uses gateways or similar devices to achieve protocol conversion, which has low scalability and is difficult to apply to scenarios where the type and number of equipment are prone to change; and because there are many network protocols involved, the existing heterogeneous network protocol processing system also has the problem of a large maintenance workload for protocol conversion.

[0027] Based on this, in order to improve the scalability of a heterogeneous network protocol processing system and reduce the workload of protocol conversion and maintenance, the present invention provides a heterogeneous network protocol processing system.

[0028] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings.

[0029] Figure 1 Schematic diagram of a heterogeneous network protocol processing system provided by an embodiment of the present invention. Figure 1 As shown, the system includes: a server 11 and at least one data access terminal 12.

[0030] The server 11 includes a protocol storage module, a first data sending module and a first data receiving module; the protocol storage module stores protocol decapsulation algorithms and protocol encapsulation algorithms corresponding to different network protocols.

[0031] The data access terminal 12 includes an interface module, a protocol decapsulation module, a protocol encapsulation module, a second data sending module and a second data receiving module; the second data sending modules and the second data receiving modules in all data access terminals 12 constitute a virtual protocol conversion wireless bus; the protocol conversion wireless bus is connected to the server 11; the protocol conversion wireless bus is also used to connect the monitoring device, and the interface module is used to connect the field terminal; the first target protocol decapsulation algorithm and the first target protocol encapsulation algorithm used by the data access terminal 12 when supporting data communication between the monitoring device and the corresponding field terminal are obtained from the protocol storage module; the first target protocol decapsulation algorithm is downloaded to the protocol decapsulation module, and the first target protocol encapsulation algorithm is downloaded to the protocol encapsulation module.

[0032] In the embodiment of the present invention, the server 11 may be an edge server. An edge server is a small server that sinks the computing power of a traditional server from a central point to a terminal close to the user. The present invention adopts an edge server, so that the present invention can shorten the delay of the data access terminal obtaining the protocol decapsulation algorithm and the protocol encapsulation algorithm, reduce the bandwidth requirement of the process, improve data security, and improve the reliability of the server.

[0033] In actual application, when the data access terminal 12 accesses a new type of on-site terminal, it needs to download the protocol decapsulation algorithm and the protocol encapsulation algorithm required by the new type of on-site terminal from the server 11 .

[0034] Based on this, in the data access terminal 12, when the interface module accesses the first target on-site terminal, the second data sending module generates a target request according to the target network protocol adopted by the first target on-site terminal; the second data sending module sends the target request to the first data receiving module, so that the server 11 obtains the second target protocol decapsulation algorithm and the second target protocol encapsulation algorithm corresponding to the target network protocol from the protocol storage module, and sends the second target protocol decapsulation algorithm and the second target protocol encapsulation algorithm to the second data receiving module through the first data sending module; the protocol decapsulation module stores the second target protocol decapsulation algorithm; and the protocol encapsulation module stores the second target protocol encapsulation algorithm.

[0035] In addition, the second data sending module can also generate a target request in combination with the device type of the first target on-site terminal. Specifically, the second data sending module determines the first data transmission requirement of the first target on-site terminal according to the device type of the first target on-site terminal, and determines the second data transmission requirement of the first target on-site terminal according to the target network protocol adopted by the first target on-site terminal. If the first data transmission requirement is consistent with the second data transmission requirement, the target request is generated according to the second data transmission requirement. The data transmission requirement includes information such as the data format of the transmission and the transmission object.

[0036] In actual application, a field terminal connected to the data access terminal 12 may disconnect the connection. At this time, the protocol decapsulation and encapsulation algorithm for the field terminal stored in the data access terminal 12 may be deleted to reduce the maintenance workload of protocol conversion.

[0037] Based on this, in the data access terminal, when the second target field terminal connected to the interface module is disconnected, the protocol decapsulation module deletes the protocol decapsulation algorithm of the second target field terminal stored therein, and the protocol encapsulation module deletes the protocol encapsulation algorithm of the second target field terminal stored therein.

[0038] In actual application, a new data access terminal 12 may be added. In this case, the second data sending module and the second data receiving module of the new data access terminal 12 will form a new protocol conversion wireless bus with the second data sending modules and the second data receiving modules of other data access terminals 12. And, subsequently, the protocol decapsulation and encapsulation algorithm acquisition process when the new data access terminal 12 accesses the on-site terminal is the same as the above solution, which will not be repeated here.

[0039] The following uses the control ball as an example to illustrate the process of data intercommunication between the monitoring equipment and the corresponding field terminal. First, the control ball sends the data it collects to the data access terminal 12 to which it is connected. The data access terminal 12 receives the data sent by the control ball through its interface module. Then, in its protocol unpacking module, the protocol unpacking algorithm corresponding to the control ball is used to unpack the data sent by the control ball. Then, in its protocol encapsulation module, the unpacked data is encapsulated according to the protocol encapsulation algorithm corresponding to the monitoring device. Then, it is packaged at the link layer according to the TLV format (Tag: identifier, L: length, V: data content) and sent to the protocol conversion wireless bus. Finally, the monitoring device obtains the packaged data from the protocol conversion wireless bus. It should be noted that the process of the monitoring device sending data to the corresponding field terminal is the same, which will not be repeated here.

[0040] In the embodiment of the present invention, the interface module may include a wired interface module and a wireless interface module, thereby increasing the richness of interface types and expanding the application scenarios of the present invention.

[0041] In the embodiment of the present invention, the wired interface module may include an RJ45 interface and an HDMI (High Definition Multimedia Interface).

[0042] The wireless interface module may include a WIFI interface and a LoRa (Long Range Radio) interface. LoRa is a long-distance wireless communication technology based on spread spectrum technology.

[0043] In the embodiment of the present invention, the interface module is used to connect at least one field terminal.

[0044] In the embodiment of the present invention, the on-site terminal includes power production equipment, power emergency equipment and personal wearable equipment.

[0045] The embodiment of the present invention adopts the above-mentioned technical solution, and the second data sending module and the second data receiving module in all data access terminals constitute a virtual protocol conversion wireless bus. The modular design makes each second data sending module and the second data receiving module an independent and replaceable component, and the wireless bus has the advantages of supporting a variety of network topologies and supporting a variety of types of device connections. This makes it possible for the present invention to add or reduce data access terminals at any time according to actual needs, thereby improving scalability and being applicable to scenarios where the type and quantity of devices are prone to change.

[0046] Furthermore, by centrally storing the protocol decapsulation algorithms and protocol encapsulation algorithms corresponding to different network protocols in the server, each data access terminal obtains the protocol decapsulation algorithm and protocol encapsulation algorithm it needs from the server, thereby realizing centralized storage and distributed application of protocol conversion data. This enables the present invention to reduce the maintenance workload of protocol conversion, and helps to avoid related problems caused by inconsistent protocol conversion data.

[0047] Furthermore, by decoupling the protocol decapsulation module from the protocol encapsulation module, great flexibility is achieved in protocol conversion.
