Abstract

The invention discloses an abnormal processing method and device for an air conditioner single-chip microcomputer. Wherein the abnormality handling method of the air conditioner single-chip microcomputer includes: monitoring the state data and communication state between the external unit and the internal unit of the air conditioner; judging whether the state data or the communication state is abnormal based on preset rules, and notifying the external unit if abnormal and / or the internal unit to reset accordingly. The invention can realize the automatic reset of the program abnormality of the single-chip microcomputer, and makes up for the defect that the existing watchdog cannot reset the program abnormality.

Description

technical field [0001] The invention relates to an abnormal processing technology of single-chip microcomputers of an external unit and an internal unit of an air conditioner, in particular to a method and device for abnormal processing of a single-chip microcomputer among the external unit and the internal unit of an air conditioner. Background technique [0002] At present, single-chip microcomputers are widely used in various air-conditioning equipment, and the normal operation of single-chip microcomputers affects the realization of the functions of air-conditioning equipment. At present, the mainstream method of monitoring the normal operation of the single-chip microcomputer generally uses a watchdog, including the use of the watchdog module inside the single-chip microcomputer, or an external watchdog module, relying on the regular dog feeding operation of the single-chip microcomputer to determine whether the chip has crashed. However, in the following cases, the pro...
