A layered program and redundant control architecture in a smart lock

Abstract

The invention discloses an intelligent lock internal hierarchical program and redundancy control framework comprising a switching module, an enable module, a one-chip microcomputer, and a management module. According to the intelligent lock internal hierarchical program and redundancy control framework, complex degree of one-chip microcomputer programming is simplified, so that program design difficulty of a complex system based on the one-chip microcomputer is reduced greatly, switching of a plurality of working modes is realized via restarting, after each time of restarting, system initialization and internal storage reallocation are carried out, so that occurrence rate of memory overflow or logical error is reduced effectively. According to the intelligent lock internal hierarchical program and redundancy control framework, redundancy control is increased, so that module self fault is controlled in a limited range, fault spreading is avoided, and reliability of program running is guaranteed effectively; and at the same time, fault error positioning is convenient to realize, and convenience of maintenance is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of intelligent lock control, and in particular relates to a layered program and a redundant control framework in an intelligent lock. Background technique [0002] Today's smart locks apply various advanced electronic technologies to the intelligent control, management and electronic control of the lock body, making them more intelligent, manageable, safe, and convenient compared to traditional mechanical locks. "Blowout" development. However, there are problems such as failure, aging, and system collapse in the electronic system. In response to these problems, some dual-circuit systems or dual-motor system smart locks have appeared in recent years, such as the utility model-invisible five-hole dual-system electronic lock. It uses two dual-circuit systems that individually control the motor, which greatly improves the security and stability of the smart lock, but the following problems still commonly exist ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above problems, the present invention provides a layered program and redundant control framework in the smart lock, which solves system problems such as memory overflow in general circuit systems, and divides business processes such as system testing, switching, and management into different levels Each module can operate independently without interfering with each other, and provides a complete work detection and switching mechanism. When switching the working state, restart the system to refresh the memory, re-plan the system, and release the memory of the previous working mode. reliability of system operation

In addition, aiming at the lack of communication between the dual systems and the lack of alternate working methods, the present invention also proposes a redundant communication mechanism for the dual systems, which effectively solves the communication and alternate work problems between the dual systems, and improves the dual function of the smart lock. Safety and stability of circuit system work
