Example Embodiment

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative pur...

Abstract

The invention discloses a USB clock module. The USB clock module comprises a USB interface circuit, a USB conversion circuit, a clock circuit and a power supply battery; the input end of the USB interface circuit is electrically connected with the output end of the USB conversion circuit; the input end of the USB conversion circuit is electrically connected with the signal output end of the clockcircuit; and the power supply input end of the clock circuit is electrically connected with the power supply output end of the power supply battery. The power supply battery in the invention can supply power to the clock circuit; the clock circuit always times; furthermore, the timed time in the clock circuit is sent to the USB conversion circuit in an SPI manner; furthermore, clock information issent to electrical equipment through the USB interface circuit; therefore, an accurate clock signal is provided after the electrical equipment is started; the USB clock module is convenient for a user and the electrical equipment to determine the time, and convenient for the user to use; furthermore, the USB clock module is convenient to plug, flexible to use and convenient to install; and furthermore, the clock signal can run continuously.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a USB clock module. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. Electrical equipment consists of two parts: power supply and electrical equipment. Power sources include batteries, generators and their regulators. Electrical equipment includes the starting system of the engine and the lighting, signals, instruments, etc. of the car, and the ignition system of the engine is also included in the forced ignition engine. Whether the electrical equipment should be connected to zero or protective grounding mainly depends on whether the neutral point of the power distribution system is grounded, the nature of the low-voltage power grid, and the tentative voltage level of the electrical equipment. In the low-voltage distribution system with good grounding of ...
