Abstract

A current monitoring system is connected to an alternating-current power supply loop consisting of an alternating-current power supply and an electronic device. The alternating-current power supply loop comprises a first power line and a second power line; the current monitoring system comprises a current detecting element, a current signal processing unit, a current switch unit, a switch control circuit and a microprocessor; the current detecting element is coupled to the first power line and the second power line; the current signal processing unit comprises a signal amplifier and an analog-to-digital converter; and the current switch unit comprises a first selector switch and a second selector switch; the first selector switch is serially connected to the first power line; and the second selector switch is serially connected to the second power line. The current monitoring system is simple in structure; current is monitored in real time by a simple circuit; the current monitoring system is convenient to mount; the circuit does not require to be modified; current can be monitored and displayed in real time; data can also be stored in the current monitoring system; and a data support is provided for a user on follow-up analysis.

Description

technical field [0001] The invention relates to a current monitoring system. Background technique [0002] With the continuous improvement of the degree of automation, more and more electronic devices are automatically monitored, and their applications are becoming more and more extensive. It can not only provide convenient and fast management, but also realize fast processing. [0003] Commonly used electronic device monitoring needs to monitor the current or voltage of the electronic device to know the information of the electric device in time. [0004] This kind of current monitoring in the prior art usually adopts a mechanical structure, which is relatively complex and expensive, and the monitoring object is relatively simple, which is prone to loopholes. [0005] For this reason, in view of the above-mentioned defects, the designer of the present invention researches and designs a current monitoring system to overcome the above-mentioned defects by concentrating on re...
