Detailed Description
All of the features disclosed in all of the embodiments of this specification, or all of the steps in any method or process disclosed implicitly, except for the mutually exclusive features and/or steps, may be combined and/or expanded and substituted in any way.
In view of the problems in the background, the current implementation structure of the baseband software up-cloud is based on the traditional monomer architecture, as shown in fig. 1, and the digital radio frequency front end downlink IP signal data is subjected to capturing, downsampling, carrier wave ring, bit ring, decoding and frame synchronization to be demodulated and output. Micro-service is taken as an important technology of cloud primordia, a cloud platform is taken as a base, a baseband measurement and control function is micro-serviced (the measurement and control function is serviced, a single measurement and control function can be provided with a plurality of examples distributed on different servers for signal processing), the important problem can be effectively solved, but the micro-service focuses on communication among services, is a concept of local processing, and does not stand on the global measurement and control link to consider the global property of signal data, so that the baseband micro-service needs to solve two characteristics of signal data of an aerospace measurement and control link: (1) sequential relevance: the IP signal data packets are sequentially sent, the packets are mutually dependent, and the signal data in figure 1 are processed sequentially through each module; (2) calculated accumulation: when the IP signal data is demodulated, the loop processing of the functional unit needs to carry out loop accumulation calculation on the signal data packet, and the calculation processing of the current signal packet depends on the result of the previous calculation.
There are two approaches to conventional microservices to solve the above problems. Taking carrier micro service and bit ring micro service communication as an example for illustration, three servers exist, and each server runs one bit ring micro service instance, then three bit ring micro service instances are total. The two schemes are specifically as follows: (1) point-to-point communication: the carrier micro-service and the bit ring micro-service are directly communicated in a unit of one packet, the carrier micro-service waits for the completion of processing of one bit ring micro-service, then signal data is sent to the next bit ring micro-service, and a loop result is read and calculated to be a durable database. (2) publish/subscribe message middleware: the services communicate through message middleware, the middleware pushes signal data, alternately waits for pushing the data to different service instances under the same micro service, and the loop result reads the calculation persistence database, as shown in fig. 2.
After further analysis by the inventors of the present invention, referring to fig. 2, it was found that the two schemes described above have the following disadvantages: (1) The signal data packets are sequentially and alternately sent to different micro service examples by taking the packets as units, one packet is sent, the next packet is passively waited to be pushed before the signal packet processing is completed, and the utilization rate of the computing resources of the server is not high. (2) The plurality of micro service examples serially receive data to perform loop calculation, only one example in a calculation state works, other examples are busy, and the like, the state examples are changed into calculation to perform data receiving and loop calculation, so that the real-time performance is poor. (3) The loop result of the instance calculation is persisted to the database, the previous result is required to be extracted from the database for each calculation, and the access efficiency is low.
In order to solve the technical problems, the technical scheme of the invention innovatively provides a micro-service data synchronization technical scheme of a cloud measurement and control baseband pool, and improves a micro-service architecture and a data synchronization flow based on the architecture so as to ensure real-time performance, sequential performance and accumulation performance of measurement and control signal data processing in a distributed environment, wherein the micro-service architecture is shown in a synchronization flow chart 7 and 8 with reference to fig. 3. The innovation points of the technical scheme of the invention mainly comprise: (1) The signal data packet pushes the same micro service instance based on the sliding window; (2) The method comprises the steps that IQ signal data are received by a plurality of micro service examples in parallel, such as a plurality of examples under bit ring micro service, the signal data are segmented, each segment is pushed to the examples in different states in parallel, and data packets are received by the computing state examples and the data receiving state examples in parallel; (3) loop result high speed memory persistence.
In a further innovation point, the corresponding data structure is improved, wherein the data structure comprises a measurement and control function theme cyclic array queue structure and an intermediate loop structure. The structure of the measurement and control function topic circular array queue is shown in fig. 4, and the array linked list is used for storing signal data packets of one topic, and one array linked list belongs to one topic. The signal data is stored in a sequence from left to right and from top to bottom to form an array of M x N signal packets. When the signal data packet is pushed to a subscriber, the signal data packet is pushed to a subscriber according to the set number of sliding windows (a window unit is a row in a signal matrix). The data length of each node in the linked list is 8000 signal bytes, and each 4 bytes represent a sampling point and comprise 1000I-path data and 1000Q-path data. Intermediate loop structure as shown in fig. 5, the bit loop example includes clock error and loop filter NCO that need to be accumulated, and the calculation of 2 values depends on the previous value to be accumulated. The intermediate loop is sent as part of the loop result response command when the signal data is switched for bit-loop micro-service instance computation.

The functional components comprise a multiplexer (socket management), a component register (subject queue, publisher and subscriber management), a measurement and control signal receiver, a sliding window pusher (signal data packet pushing), a flow controller (signal command control word processing) and a state receiver, and the functional components complete interaction with each micro service instance according to the signal data packet control command.

The received signal data of the bit ring example 1 and the bit ring example 2 are received simultaneously, and the data parallel reception is completed.
Step 4: the intermediate loop result is responsive to the control command: after the example 1 calculates the N packets of data of a linked list, setting the calculation state as ready, sending a middle loop result response command code to the measurement and control middleware, directly forwarding the IO multiplexer of the measurement and control middleware to the example 2, and simultaneously delivering the IO multiplexer to a loop state machine, wherein the loop state machine stores the calculation result of the 1 st round into the loop state machine.
Step 5: the following example state starts: the IO multiplexer sends a calculation starting command (comprising a loop result of the previous round) to the example 2, the example 2 enters a starting state from a stopping state to calculate, meanwhile, the sliding window polling pusher judges whether the number of the examples pushed at the moment is 2, if so, the IO multiplexer still sends the data packet, and if not, the sliding window operation is carried out to push the data packet of the next linked list to the next example.
