KR20100079288A - Wireless digital high sensitivity electric current sensor - Google Patents

Abstract

The present invention provides a separate proximity to the operation of home appliances and industrial electronic devices that use general power line (AC 220V or AC 110V) as a power source of UBIQUITUS SENSORS NETWORK (USN), which is emerging as a core technology field of ubiquitous. It's about a current sensor that can be found in place.

In general, current detectors are used to detect overcurrent (15 A minimum) in devices such as overcurrent breakers (earth leakage breakers) that detect and cut off excessive current to protect the entire plant system or the plant itself. The need for monitoring the operating conditions such as air conditioners and heaters (eg, going out with the air conditioner on) is increasing in order to save energy.

The present invention is to amplify and filter the induced AC voltage through the electromagnetic induction ring to the existing AC line to grasp the flow of current, and the detected signal is an external information processor through a wireless network such as Zigbee built-in Is sent.

The digital wireless current detector of the present invention can be installed simply without changing any existing equipment and can remotely check the operation of electronic / electrical devices (whether air conditioners or heaters operate), thereby saving energy. It can be utilized for a lot of facilities.

Wireless (wired) communication technology

(1) high sensitivity current detector manufacturing technology

(2) filtering technology

(3) Zigbee wireless communication technology

In the present invention, home appliances and industrial electronic devices that use a general power line (AC 220V or AC 110V) as a power source without changing the existing equipment can be reliably used even in a noise environment generated from noise generated from AC power or various signal lines. We want to make a high-sensitivity current detector to check the operation of electrical equipment. In addition, the sense signal must be transmitted wirelessly so that it can be easily centrally grasped.

The present invention amplifies the induced AC voltage by simply applying an electromagnetic induction ring to the existing AC line, and detects the presence or absence of operation by filtering out various noises, the detected signal through a wireless network such as Zigbee built-in Send to central processor.

Since the digital wireless current detector of the present invention is a wireless method, it is possible to check the operation of electronic / electrical devices remotely (with or without air conditioners) by simply installing it without the need for wiring work, thereby saving energy. It can be utilized for a lot of facilities.

The digital wireless high-sensitivity current detector of the present invention is a high-sensitivity current detector of a terminal, which is a central item of the UBIQUITUS SENSORS NETWORK, which is emerging as a core technology field of ubiquitous, and uses a general power line (AC 220V or AC 110V) as a power source. It is a method to detect the operation status by amplifying and filtering the induced AC voltage by simply applying the electromagnetic induction ring 102 to the existing AC line so as to wirelessly detect the operation signal of home appliances and industrial electronic devices. There is no change in equipment. The detected signal is transmitted to the central processor through a wireless network such as Zigbee, and the data received from the central processor is aggregated and analyzed.

The digital wireless current detector of the present invention can be easily installed to remotely check the operation of electronic / electrical devices (whether air conditioners or heaters operate), and can be utilized in energy saving facilities.
