Detection and judgment method for shutdown control

Abstract

The invention relates to a detection and judgment method for shutdown control. The method comprises the following steps: an infrared transponder receives a close instruction sent by a remote control device; the infrared transponder sends a close control signal to a controlled device according to the close instruction in a first moment; a power supply device supplies power to the controlled device, a current detector detects power supply currents of the power supply device, the power supply current before the first moment is a first power supply current, the power supply current after the first moment is a second power supply current, and the first power supply current and the second power supply current are sent to a processor; and the processor executes judgment according to the first power supply current and the second power supply current and judges that the controlled device is shut down when the second power supply current is smaller than the first power supply current and the difference between the first power supply current and the second power supply current is not smaller than a preset power supply threshold. According to the detection and judgment method, a user can know whether the controlled equipment is successfully shut down in real time without modifying a protocol of the infrared transponder.

Description

technical field [0001] The invention relates to the field of smart devices, in particular to a detection and judgment method for shutdown control, which is mainly used to solve the problem that an infrared transponder cannot confirm whether the shutdown operation is successful. Background technique [0002] With the development and changes of social economic structure, family population structure and information technology, and the improvement of human beings' requirements for the safety, comfort and efficiency of the home environment, the demand for intelligent home furnishing has greatly increased. At the same time, more and more families require Smart device products not only need to meet some basic needs, but also require the smart device system to be simple, convenient and safe in terms of function expansion, extension and even service. [0003] Infrared transponder is a wireless signal transceiver device, with infrared signal learning and memory functions, intelligent ...

AI Technical Summary

Problems solved by technology

[0004] At present, in the application process of the infrared transponder in the smart device system on the market, due to the limitation of the infrared transponder protocol, the infrared transponder cannot receive the status feedback of the operated device after sending the shutdown command, and cannot judge whether the operation is successful. Therefore It brings great inconvenience to the user's use process, and the user cannot immediately grasp the status of the operated equipment
