Embodiment
As shown in Figure 1, the big-dipper satellite-signal civil processing system of the present invention's proposition is made up of satellite interface machine, core processing machine, public network interface three parts.
As follows for the downlink data handling process:
The downlink data handling process is meant that the data that the big-dipper satellite terminal sends to Beidou satellite navigation system are transmitted to the core processing machine after the satellite interface machine receives, and the core processing eedle carries out corresponding service processing after public network interface sends to end user's process to the different types of business under the data.
Present embodiment sends the data to the user with the form of mobile phone short message.
The satellite interface machine is responsible for receiving the data that Beidou satellite navigation system is distributed, and is sent to data parsing, conversion process.Data parsing, conversion process are the data that Beidou satellite navigation system is distributed to be carried out preliminary treatment (comprise part message screening, message format conversion, message priority is determined), then data processed is put into message queue, give the core processing machine by message queue; Data are deposited in the database of satellite interface machine simultaneously.Flow chart of data processing figure such as Fig. 2 of satellite interface machine.The satellite interface machine data receives flow chart such as Fig. 8.
The core processing machine is that the core processing machine connects public network interface and satellite interface machine, carries out Business Processing and forwarding respectively for satellite-signal and public network signal.The basic structure of core processing machine as shown in Figure 3, the flow chart of data processing of core processing machine is as shown in Figure 9.
Principle based on modularized design is divided into following submodule with the core processing machine:
The formation receiver module
The message pretreatment module
The message distribution module
Service Processing Module
Public module
Data queue's transceiver module
The satellite interface machine is sent to the formation receiver module of core processing machine with data, and the formation receiver module is sent to the message pretreatment module with data.
Message pretreatment module flow chart of data processing such as Fig. 4.The message pretreatment module is at first disassembled packet, then user's service authorization is verified; After by the service authorization checking, send the packet after disassembling to the message distribution module.For those message that do not need to carry out service authorization checking warning message for example, the message pretreatment module directly is transmitted to the message distribution module without the user right authentication and handles.
The message distribution module receives the data of having verified by subscriber authorisation, and the class of service under the judgment data is called the corresponding service processing module and carried out data processing.Data distribution module flow chart of data processing such as Fig. 5.
Service Processing Module carries out the data of receiving after the corresponding service processing, and submodule is served in the formation that data processed is transmitted in the public module.Service Processing Module flow chart of data processing such as Fig. 6.
As Fig. 3, public service module comprises formation service submodule, directory service submodule, database service submodule, the service submodule charges.The public module major function comprises:
υ formation connection pool
The υ database connection pool
The υ log pattern
υ XML interpreter object
υ format character stream packet parsing device
υ binary stream packet parsing device
υ abnormality processing module
υ binary stream object
The υ date is stabbed object
υ synchrolock object
The queue server submodule calls the database service submodule after receiving the data that Service Processing Module transmits, and storage in database, is meanwhile called the directory service submodule and chargeed the service submodule.Directory service is a computer management tools, makes directory information be easy to management and search more; The service submodule employing uniform data model of chargeing reflects the business datum of various charging ways, the consumption situation of the different services of reflection on same bill.Formation service submodule forwards the data to data queue's transceiver module.
So far the core processing machine has been finished all Business Processing of the data-signal that the satellite interface machine is sent, and gives public network gateway with the data forwarding after the Business Processing.
As shown in Figure 7, public network gateway comprises formation service module, monitoring module, message dispatch module, uses access module.The formation service module is given the message dispatch module with data forwarding after receiving the data that the core processing machine is sent to, and the message dispatch module sends data to end user in the mode of web, email, mobile phone short message, group user special line, marine satellite terminal.Monitoring module is monitored the operating state of public network gateway at any time, produces wrong, fault message immediately in case break down.
The upstream data handling process is as follows:
The upstream data handling process is that the end user is transmitted to the core processing machine with data through public network interface, the core processing eedle carries out corresponding service processing to the variety classes service request under the data, send to Beidou satellite navigation system through the satellite interface machine then, be sent to the big-dipper satellite terminal by Beidou satellite navigation system.Upstream data handling process such as Figure 12.
The mode of end-user electronic mail, the Internet, mobile phone short message, group user special line, marine satellite terminal sends data to public network gateway.The application access module of public network gateway is transmitted to the core processing machine by the formation service module after receiving user's data.
Present embodiment is that the user sends request with the mobile phone short message form.
The public network module receives handling process such as the Figure 10 after user's short message.
The core processing machine is given the message distribution module after receiving the next data of public network module forwards.Class of service under the message distribution module judgment data is called the corresponding service processing module and is carried out data processing.Data distribution module flow chart of data processing such as Fig. 5.
Service Processing Module carries out the data of receiving after the corresponding service processing, and submodule is served in the formation that data processed is transmitted in the public module.Service Processing Module flow chart of data processing such as Fig. 6.
After treated data were forwarded to the satellite interface machine by the core processing machine, the satellite interface machine sent to Beidou satellite navigation system with data, and Beidou satellite navigation system sends to data the big-dipper satellite terminal again.Satellite interface machine handling process such as Figure 11.
