Description

technical field [0001] The invention relates to a time-delay relay, which is suitable for a counting device or a similar control device of water, electricity, gas meters and other metering instruments. Specifically, it relates to a control device for realizing intermittent operation of a single-chip microcomputer, which belongs to the field of electronic technology. Background technique [0002] The existing sensing and counting devices for various measuring instruments generally use a single-chip microcomputer to collect measuring and sensing signals, such as described in Chinese patents 20220531067.4, 201110267269.2, and 201020544489.6. These methods are to keep the single chip microcomputer in the state of power on for a long time, and then collect the pulse or switch signal from the sensor. Regardless of whether the signal comes or not, and when it comes, the microcontroller must remain powered on. Many problems arise from this. The first is the problem of external int...
