[0120] V. Data storage unit The data storage unit is responsible for data storage management.

[0121] The data storage unit includes a standard database, an original database, a data backup library, and a cache. The standard database is used to store the converted standard protocol data; the original database is used to store the original data reported by the terminal devices; the data backup library is used to store the data that needs to be retained for a long time; the cache is used to store and retrieve the data for the application system services and other frequently used data.

[0123] S2, Command reception and processing: The application system issues a terminal device control command to the system of the present invention, and the command is routed to the data processing unit. The data processing unit automatically calls the configuration information of the relevant application read by the parameter configuration unit and parses the command according to the configuration information; If it is a query command, first check whether the query content exists in the cache of the data storage unit. If it exists, return directly; if it does not exist, directly issue the command. If it is other types of commands, directly issue them.

[0124] S3, Convert the command according to the protocol: The terminal device control command is forwarded by the data processing unit to the protocol conversion unit. After receiving the command, the protocol conversion unit first reads the data protocol configuration information through the parameter configuration unit, then parses the command and reorganizes the command into a protocol command recognizable by the terminal device according to the corresponding data protocol, and then issues the command to the terminal communication unit.

[0125] S4, Issue the command to the terminal device: The terminal communication unit receives the commands parsed by the protocol conversion unit, reads relevant configuration information through the parameter configuration unit to load the communication protocol, and issues communication commands recognizable by various terminal devices to achieve the scheduling of different terminal devices.

[0127] S6, Data conversion according to protocol: After receiving the original data returned by the terminal communication unit, the protocol conversion unit first reads the data protocol configuration through the parameter configuration unit, then loads the corresponding data protocol to parse the original data, reorganizes the data according to the standard protocol, and finally stores the standard protocol data in the standard database of the data storage unit and forwards it to the data processing unit.

[0128] S7, Data reorganization: After receiving the standard protocol data returned by the protocol conversion unit, the data processing unit first reads the application system configuration information through the parameter configuration unit, then reorganizes the data according to the data format required by the application system and updates the cache of the data storage unit, and finally returns the data according to the interaction method required by the application system.

[0129] S8, Data storage.

[0130] During the use of the system of the present invention, the converted standard protocol data is managed by the standard database; the original data reported by each terminal device is managed by the original database; the data that needs to be retained for a long time is managed by the data backup library; the cache is used to store and retrieve data for application system services and other frequently used data.

[0131] Embodiment 1 In a certain centralized monitoring and scheduling project, it is necessary to connect various devices connected to terminals such as on-vehicle, on-aircraft, and on-satellite to various application systems such as the already established centralized monitoring system and business system, and provide data services for these application systems. The terminal devices to be connected all have their own control software, but their communication protocols are different (UDP, PDXP, FEP...), and their data protocols are also different (different devices have different protocols, and the same protocol has different versions, such as protocol 1.1, protocol 1.2, protocol 2.1, protocol 3.1, protocol 3.2, protocol 3.3...).

[0132] In order to reduce the integration difficulty, improve the data service ability, enhance the system scalability, and compress the R & D cost, the present invention is adopted for the integration and scheduling of multi-source heterogeneous terminal devices, specifically as Figure 2 , Figure 3 shown.

[0133] During the project construction process, the integration of multi-source heterogeneous terminal devices was quickly completed through the present invention; the system of the present invention sends relevant commands to each terminal device to complete the scheduling of the terminal device; receives various types of data reported by the terminal device and feeds it back to the centralized monitoring system; automatically performs the conversion of standard protocol data / non-standard protocol data during the communication process. The specific steps are as follows: 1. Parameter configuration Configure the information of each application system parameter, terminal device parameter, data protocol, and communication protocol in the parameter configuration unit of the system of the present invention according to actual needs, as Figure 4 shown. The specific process of parameter configuration is as follows: (1) Each application system administrator starts the parameter configuration operation in the system of the present invention; (2) The system of the present invention checks whether there is a corresponding data protocol according to the data protocol input by each application system administrator; (3) If there is no corresponding data protocol, jump out of the data protocol addition page and prompt each administrator to add the corresponding data protocol first; (4) If there is a corresponding data protocol, the system of the present invention performs a communication protocol check to determine whether there is a corresponding communication protocol; (5) If there is no corresponding communication protocol, jump out of the communication protocol addition page and prompt each administrator to add the corresponding communication protocol first; (6) If there is a corresponding communication protocol, pop up the application information filling page and prompt each administrator to fill in the application information; (7) After the application information is filled in and automatically checked by the system of the present invention without error, pop up the data protocol selection page and prompt each administrator to select the corresponding data protocol; (8) After the data protocol is selected and automatically checked without error, pop up the communication protocol selection page and prompt each administrator to select the corresponding communication protocol; (9) After all information is configured, each administrator can click the "Save" button to end the parameter configuration operation.

[0134] 2. Command reception and processing The application system issues a terminal device control command to the system of the present invention. This command is routed to the data processing unit of the system of the present invention. The data processing unit automatically calls the configuration information of the relevant application read by the parameter configuration unit and parses the command according to the configuration information, as Figure 5 shown. The specific process of command reception and processing is as follows: (1) Receive the request commands sent by each application system to the system of the present invention; (2) Invoke the "parameter configuration" unit to read the configuration information of relevant applications; (3) The system of the present invention automatically authenticates the requester's authority and determines whether the request content has been authorized; (4) If the "authentication" fails, pop up the corresponding feedback prompt information to each system administrator; (5) If the "authentication" passes, parse the command according to the configured information; (6) After the command parsing is completed, the system of the present invention automatically identifies the command content; (7) If the command is a query command, check the cached data. If the data satisfying the command exists in the cache, directly push the corresponding data to the corresponding interface; (8) If the command is a query command and the corresponding data does not exist in the cache, or the command is other commands, issue a request according to the command content; (9) Feed back the request result to the application side.

[0135] 3. Convert commands according to the protocol As Figure 6 shown, the terminal device control command is forwarded to the protocol conversion unit via the data processing unit. After receiving the command, the protocol conversion unit first reads the data protocol configuration information through the parameter configuration unit, then parses the command and reorganizes the command into a protocol command recognizable by the terminal device according to the corresponding data protocol, and then issues the command to the terminal communication unit.

[0136] 4. Issue commands to terminal devices As Figure 7 shown, the terminal communication unit receives the command parsed by the protocol conversion unit, loads the communication protocol by reading the relevant configuration information through the parameter configuration unit, and issues communication commands recognizable by various terminal devices, so as to realize the scheduling of different terminal devices.

[0137] 5. Terminal device monitoring As Figure 8 shown, when initializing, the terminal communication unit traverses all terminal devices that need to be monitored by the system of the present invention, schedules the communication protocol according to the configuration information of the terminal devices, establishes a connection with the terminal devices and monitors the terminal devices. After receiving the information reported by the terminal devices, the terminal communication unit stores this original data in the original database and returns it to the protocol conversion unit.

[0138] 6. Convert data according to the protocol As Figure 9As shown, after the protocol conversion unit receives the original data returned by the terminal communication unit, it first reads the data protocol configuration through the parameter configuration unit, then loads the corresponding data protocol to parse the original data, reorganizes the data according to the standard protocol, and finally stores the standard protocol data in the standard database and forwards it to the data processing unit.

[0139] 7. Data Reorganization As Figure 10 shown, after the data processing unit receives the standard protocol data returned by the protocol conversion unit, it first reads the application system configuration information through the parameter configuration unit, then reorganizes the data according to the data format required by the application system and updates the cache, and finally returns the data according to the interaction method required by the application system.

[0140] 8. Data Storage During the use of the system of the present invention, the converted standard protocol data is managed by the standard database; the original data reported by each terminal device is managed by the original database; the data that needs to be retained for a long time is managed by the data backup library; the cache is used to store and retrieve data for the application system service and other frequently used data.
