Research And Realization Of Localization For Dual-screen Community Correction Self-service Terminal

In the process of promoting the digitization,informatization and intelligence of various industries such as judicial community corrections in our country,cybersecurity incidents have occurred repeatedly,seriously threatening national interests and security.Especially since2018,the outbreak of the "ZTE and Huawei Incident" has exposed the current situation that Chinese upstream core technologies such as core chip and operating system are controlled by others.Therefore,it is urgent to realize the localization of critical information infrastructure,which is independent,controllable,safe and reliable.This paper takes the dual-screen community correction self-service terminal in the judicial field as the main body of development for localization transformation and migration.Through the investigation and analysis of the current situation of localization transformation,it summarizes the problems and difficulties in the process of localization transformation of self-service terminals,and mainly carries out the following researches on the localization transformation of the main control system and the localization migration of the peripheral drivers:(1)By investigating the development status of domestic CPUs and domestic operating systems,we decide to take Phytium CPU equipped with Kylin operating system as the localization transformation plan for the main control system of the dual-screen community correction self-service terminal,and summarize the problems and difficulties of localization transformation.We determine the selection of domestic CPU motherboards.At the same time,for the application scenarios of dual-screen community correction self-service terminals,we use the operating system adaptation optimization technology to tailor,optimize and customize the domestic Kylin operating system,and design and develop system components based on inter-process communication to realize low-latency and high-efficiency inter-process communication.At the same time,at the image transmission level of the system,an image transmission strategy based on running face recognition algorithm and virtual camera in the backstage is proposed,which improves the efficiency of image transmission and the accuracy of face recognition on domestic platforms.(2)The localization transformation for the main control system of the dual-screen community correction self-service terminal makes the original brand peripheral drivers unable to be reused under the domestic platform.Through the research on the self-service terminal driver and middleware communication mechanism,a set of middleware platform based on self-service terminal is developed to provide a peripheral device management method that can automatically load or unload the peripheral device driver when the peripheral device is inserted or pulled out;For different types of peripherals,we establish a general peripheral driver management resource pool and a biometric peripheral management resource pool,and encapsulate the correction application business into a unified JS standard interface for the upper-level community,which greatly simplifies the development difficulty of upper-level applications and shortens the localization migration cycle of old applications on localized platforms.Through this study,the feasibility of the localization transformation of the dual-screen community correction self-service terminal is preliminarily verified,and the successful pilot application is carried out in the judicial units to establish an industry demonstration of the localization transformation in the judicial field.
