The control device comprises a trigger signal generating device and a transistor time-delay relay, the trigger signal generating device is used for generating trigger signals and is provided with a first delay level to delay the trigger signals, the transistor time-delay relay is electrically connected with the trigger signal generating device and is provided with a second delay level, the transistor time-delay relay is used for receiving the trigger signals to connect, delay and close a working power supply of the single-chip microcomputer , and the retardation of the first delay level is larger than that of the second delay level. The transistor time-delay relay comprises a trigger circuit and a fast discharge reflex circuit, the trigger circuit is composed of a filed-effect tube, a resistor and a capacitor, and the fast discharge reflex circuit is composed of a filed-effect tube and a resistor. The transistor time-delay relay is contactless, small in size, less in power consumption, low in cost, interference resistant, stable in performance, convenient to integrate and package and accurate in metering when applied to the intelligent meters of water, power and gas.

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...
