A circuit for generating a clock pulse signal based on alternating current

Abstract

The invention relates to the technical field of synchronous control and discloses a circuit for generating clock pulse signal based on alternating current. In accordance with that present invention, anovel circuit for converting an alternating current signal in a power supply network into a frequency-doubled clock pulse signal is provided, as a consequence, after the novel circuit is arranged inthe intelligent product, the output clock pulse signal can be used as the input signal of intelligent products internal counting / timing circuits and other units, therefore, not only can the crystal oscillator circuit unit be removed to avoid the frequency offset phenomenon and timing deviation caused by the working temperature, but also the same clock pulse signal can be obtained in a plurality ofintelligent products connected to the same power supply network, so as to realize the purpose of synchronously controlling a plurality of intelligent products and meet the requirements of intelligenthome. In addition, independent communication modules are not required for each intelligent product, which can reduce the cost, facilitate the volume miniaturization of the product, and avoid the influence of communication interference on the consistency of synchronization control.

Description

technical field [0001] The invention belongs to the technical field of synchronous control, and in particular relates to a circuit for generating clock pulse signals based on alternating current. Background technique [0002] In the smart home, many products are becoming more and more intelligent, that is, by running the intelligent program built into the product, the corresponding intelligent functions can be realized. However, in the process of running an intelligent program, the crystal oscillator circuit unit is generally required to provide a constant frequency clock pulse signal. If you want to synchronously control more than two smart home products, such as smart lights, a family has multiple lights. If you want to synchronize To control the brightness or color changes of these lights, there will be the following technical problems: (1) If an independent communication module (such as RS232 interface or WiFi wireless communication module, etc.) is configured for each s...

However, in the process of running an intelligent program, the crystal oscillator circuit unit is generally required to provide a constant frequency clock pulse signal. If you want to synchronously control more than two smart home products, such as smart lights, a family has multiple lights. If you want to synchronize To control the brightness or color changes of these lights, there will be the following technical problems: (1) If an independent communication module (such as RS232 interface or WiFi wireless communication module, etc.) is configured for each smart home product, and through these communication modules Controlling the collaborative work of multiple products will undoubtedly increase product cost and volume; (2) If these smart home products do not have independent communication modules, they can only rely on the crystal oscillator circuit unit in the product for accurate timing (that is, to provide clock pulses). signal), and realize synchronous control based on the same clock pulse signal, but in the actual application process, due to temperature changes, the frequency deviation of the crystal oscillator will occur, which will cause differences in the internal clock pulse signals of each product, which will lead to differences between products. Synchronization of is no longer possible
