Process data read-write optimization method and system of mobile system

Abstract

The invention discloses a process data read-write optimization method and a system of a mobile system. The method comprises the steps of through conversion of three processes, when the main socket receives a read-write request of each read-write process, reading and writing data of the server side according to the reading and writing request; sequentially putting the read-write processes into a data access queue according to the occurrence sequence of the read-write requests, writing the unfinished read-write requests into a process record queue by the inspection process, and converting the inspection process into a blocked state when the number of the read-write requests in the process record queue is greater than a record threshold; under the condition that the process is disconnected with an online database or other data sources, ensuring normal work of the application of the terminal equipment; and a recovery mechanism is provided, so that the process of the terminal equipment cannot be deadlocked. The data read-write process of the process is not influenced in the area switching of the network communication base station; and the phenomena of jamming and false death of a terminal device program are reduced.

Description

technical field [0001] The present disclosure relates to the fields of mobile devices and process scheduling, and in particular to a process data reading and writing optimization method and system for a mobile system. Background technique [0002] In mobile systems and Internet of Things devices, data reading, writing and uploading are much more complicated than traditional data reading and writing. Therefore, mobile devices often freeze, I / O reading and writing timeouts, etc.; the process of reading and writing data is a process Entity, each process has its own address space, the address space generally corresponds to a file, and generally includes text area, data area and stack. The text area stores code executed by the processor; the data area stores variables and dynamically allocated memory used during process execution; the stack area stores instructions and local variables for active procedure calls. [0003] When the process reads and writes data, the following prob...

AI Technical Summary

Problems solved by technology

[0003] When the process reads and writes data, the following problems are often encountered: 1. The process system is often disconnected from the online database or other data sources. In the case of disconnection, data cannot be sent or received, and data is needed exchanged protocol not working

2. The connection area of ​​the network communication base station can be switched at any time, and the area switching may affect the data reading and writing process of the process; 3. Unreliable connection of the network: in some objective reasons such as signal blind areas and weak signal areas, the network is unreliable, thus making the network unreliable. The process deadlock on the mobile device end or the Internet of Things terminal, resulting in program freezes, suspended animation and other phenomena that are difficult to overcome with existing technical means
