Abstract

The invention discloses a dual-core work system and method for an electronic tag system. The dual-core work system comprises a main controller and a monitoring controller. A corresponding IO interface of the main controller is connected with a corresponding IO interface of the monitoring controller through an interface circuit, and a wireless transceiver is internally or externally arranged on the main controller in a connecting mode. According to the dual-core work method, the work mode that the main controller and the monitoring controller are in mutual real-time monitoring and regular restoration is mainly used. The dual-core work system and method can meet the requirements for being strong interference resistance, low in cost, low in power consumption, capable of achieving monitoring in real time, and capable of completely solving the problem of dead halt and restoring regularly of the electronic tag system at present, and is particularly suitable for electronic tag systems under complex electromagnetic environments.

Description

technical field

[0001] The invention relates to a dual-core working system and method for an electronic label system, belonging to the technical field of electronic labels. Background technique

[0002] In civilian systems of electronic products, there are more and more applications of single-chip microcomputers. At present, due to system interference factors, design defects and other problems, the phenomenon of "crash" frequently occurs due to the fact that the single-chip microcomputer cannot be started or cannot be executed normally according to the predetermined program after startup. When the controller MCU is used, it will cause the value of the program counter in the controller MCU to change, causing program confusion and system out of control. Therefore, when designing a single-chip microcomputer system, how to find that the controller MCU is disturbed, and how to restore the system to the normal working state without disturbance as much as possible is the main prob...
