Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the present invention is based on a preferred embodiment of a smart watch key detection method. The intelligent meter in the embodiment comprises a real-time clock, a key, a controller and a voltage detection module capable of detecting the voltage of the intelligent meter.
In this embodiment, the key detection method based on the smart watch includes the following steps:
step 1, when a mains supply is in a power failure or power failure state, a liquid crystal screen of an intelligent meter is cleared, and the intelligent meter is in a sleep state;
step 2, the real-time clock can enable the keys to work within t1 time, so that the liquid crystal display of the intelligent watch can be enabled; in this embodiment, t1 is 1s, that is, the real-time clock can make the liquid crystal of the smart meter have a display function within 1 s.
Step 3, pressing the key, detecting whether the key is always in a low level state, if so, executing step 4, otherwise, executing step 5;
