Embodiment Construction

[0022] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0023] see figure 1 , a highly reliable and lossless data acquisition and storage method, the specific steps are as follows:

[0024] (1) Start the system. After the server receives the network data from the client, it first inserts the data into the tail of the sending data cache queue, and notifies the database storage thread, and then stores the network data according to the massive storage overhead cache algorithm;

[0025] (2) Then notify the data sending module to send, the data sending module is an infinite loop sending processing thread, connects to the current main collection and transmission server, and uses an asynchronous non-blocking method to send network data;

[0026] (3) When there is data in the sending data buffer queue, read the sendable data from the head of the sending data buffer queue, call the underlying API function async...

Abstract

The invention discloses a high-reliability and lossless data acquisition and storage method. After receiving network data sent by a client, a server inserts the data into the tail of a message sendingqueue, informs a database storage thread and then stores the network data according to a massive storage overhead caching algorithm; the database storage thread reads the data from the head of the message sending queue and inserts the data into a background database; and a heartbeat message is sent between a main acquisition and transmission server and a slave acquisition and transmission serverregularly to detect the survivability of the main server. According to the method, the data can be sent to a server module in a high stability and high reliability mode in the high traffic and outburst huge traffic environment, and meanwhile it is guaranteed that the acquired data is losslessly forwarded to the background database on the abnormal condition generated in the switching process of a main server module and a slave server module.

Description

technical field [0001] The invention relates to the technical field of information collection and analysis, in particular to a highly reliable and lossless data collection and storage method. Background technique [0002] During the operation of the data acquisition system, it is necessary to record the parameters, status and other information of the system operation for future analysis of the system status. The military data acquisition system operates on airborne equipment in the field. It mainly operates in the field, and the external environment is harsh. situation. [0003] At present, the dual-machine backup technology is used to ensure the high reliability of data collection. The dual-machine backup includes the backup of the collection process and the backup of background data. Engine and database storage backup purpose; and the collection process backup is due to the different application purposes of each system. Currently, there are relatively few architectures d...
