Abstract

The invention discloses a QNX operation-based embedded APP system. The system comprises an APP launcher, an authorization manager and an APP window manager, wherein the APP window manager manages the display of a plurality of windows through an interface of an HMI; the APP window manager further comprises a PPS API and a Screen API; and the APP launcher serves as an intermediate layer, notifies the HMI and the APP window manager to launch a display mechanism, and performs digital signature examination through the authorization manager. According to the system, the authorization manager is set for an APP of an embedded operation system, the APP windows are subjected to digital signature and examination, and the permission setting is performed, so that the APP security of the APP system is improved, the APP is ensured to only access system services developed for the APP, the security is ensured, and the stability of the whole system is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of software development, in particular to an embedded APP system based on QNX operation. Background technique [0002] With the continuous popularity of medical electronics, smart home, logistics management and power control, embedded systems use their own accumulated experience to pay attention to and grasp this opportunity, and find ways to integrate with application sensing on the basis of mature platforms and products. The combination of units expands the supporting capabilities of the Internet of Things and perception, and explores the application of the Internet of Things in certain fields. As an embedded system that is an important technology component of the Internet of Things, the perspective of an embedded system is helpful for a deep and comprehensive understanding of the essence of the Internet of Things. [0003] Aiming at the problems of low security and system instability of the embedded APP ...
