Embodiment Construction

[0026] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] figure 2 is a schematic diagram of a delay control circuit according to an embodiment of the present invention. Such as figure 2 As shown, the delay control circuit includes: a trigger circuit, a voltage regulator IC (U1 in the figure) and a micro control unit MCU. The trigger circuit can be used to receive an optical signal (the optical signal can be a visible light signal), and convert the optical signal to obtain a level trigger signal. The enable pin EN of the voltage stabilizing IC is connected to the output terminal of the trigger circuit, and is used for receiving the level trigger signal and outputting electric energy under the trigger of the level trigger signal. The volta...

Abstract

The invention discloses a time-delay control circuit and a time-delay control system. The time-delay control circuit comprises a trigger circuit for receiving optical signals and obtaining level trigger signals based on the optical signals; a voltage stabilization IC, of which the enabling pin is connected with the trigger circuit and which is for outputting electric energy under the triggering of the level trigger signals; and a micro-control unit, of which the I / O pin is connected with the enabling pin of the voltage stabilization IC and which is for carrying out time-delay control on the electric energy output by the voltage stabilization IC. Through the time-delay control circuit and the time-delay control system, power consumption of the time-delay control circuit is reduced.
