The present invention relates to an intelligent power supply system and device having wireless identification and more particularly to an intelligent receptacle using an RFID wireless identification technique in collaboration with an intelligent chip module to collect and transmit related information through a network to a remote monitoring and control center, thereby precisely locating irregular wiring and power supply conditions, facilitating wire and equipment maintenance, and effectively obtaining power efficiency of equipment in a region on a real-time basis.
New generation intelligent receptacles having intelligent chip modules are used to detect the power consumption of multiple electric appliances connected therewith. When any of the electric appliances undergoes an irregular power supply condition and is automatically powered off, power consumed in a region where the electric appliances are located can be digitally managed to make power allocation more flexible and safe and achieve energy economy targets and power-savings effects. Despite fulfillment of switch control and power management objectives, conventional intelligent receptacles are unable to identify the electric appliances plugged therein. Hence, when each electric appliance is connected with another receptacle or is changed to another operating environment, setting up the electric appliance once again gives rise to inconvenience in terms of equipment management. In fact, the feature of purely controlling and limiting power supply of the receptacle is not enough to effectively keep track of actual power consumption of all electric appliances in an identical power supply region. Incomplete collection of power consumption information is never sufficient to realize remote monitoring and control of power consumption in the region at all times.
Such issues, reflecting on aspects advanced information technology (IT) industries, are aggravating. For example, whether regular large scale keyboard-video-mouse (KVM) switches or the rapidly developing cloud computing in networking applications nowadays, a data center is usually equipped with a tremendous number of servers combined to achieve practical functions as demanded. When taking more compact computer servers but higher computing power and denser power-consuming equipment into account, the required power supply allocation and management is challenging indeed. Besides, to ensure operational stability around the clock, regular data centers plan on and are designed to inevitably consume more power. An electric bill and maintenance charge arising from inefficient power utilization can be staggering and run counter to energy economics concepts.
To keep up with the constant addition of equipment, network complexity and continuous expansion of the network, servers and storage media in data centers cannot help multi-fold growth in terms of quantity. Such expansion oftentimes results in space shortage, multifarious and messy wires and disorderly generatrix in data centers. As all equipment in a data center must be connected with external power sources and densely arranged in the same space, if certain equipment abnormally consumes more power or any obsolete power supply is about to be fail, detecting such a problem beforehand is totally beyond the capabilities of conventional intelligent receptacles. The mentioned problem can only be identified and fixed after its occurrence. Upon identifying and maintaining the wiring problem, service personnel on site need to move out each equipment and check power cables one by one to make sure that power supplied to the equipment therethrough is normal. Besides the time-consuming troubleshooting, the maintenance costs are high and the operational efficiencies are poor. Furthermore, data centers are usually full of hubs ending up with twisted and entangled power cables and network lines all around, which worsen the wire spotting problem and easily trip up passerby to cause power shutdowns and heavy loss of equipment and information.
The objective of the present invention is to provide an intelligent power supply system, which employs an RFID wireless identification technique in collaboration with multiple intelligent receptacles respectively equipped with multiple intelligent chip modules mounted in multiple power sockets of the receptacles, to precisely locate each electric appliance within a region and power consumption information of the electric appliance so that the collected product and power consumption information is transmitted to a remote site for instant monitoring and control through a network, thereby facilitating the management of power utilization efficiencies of equipment inside a region and reducing the severity of equipment damage and data loss caused by abrupt power outages, including regular power supply detection and allocation, automatic power-off protection upon power irregularity detection, and early notice of obsolete parts.

The present invention will now be described more specifically in terms of structure and applications thereof with reference to the following embodiments. With reference to
Each one of the at least one electric appliance 1 has a power plug 11 and an RFID wireless identification transmitter 12. The RFID wireless identification transmitter 12 is connected to a power supply loop 10 or specifically mounted on the power plug 11 of the electric appliance 1 to wirelessly transmit signals each having an identification number (ID) of the electric appliance 1.
Each receptacle 2 has multiple power sockets 20, an RFID wireless identification receiver 21, multiple power measuring units 22 and multiple power control units 23. The power sockets 20 are formed in the receptacle 2. The RFID wireless identification receiver 21 is mounted on the receptacle 2 to detect the ID of the electric appliance 1. Each power measuring units 22 and one of the power control units 23 are mounted inside one of the power sockets 20.
Each control circuit 3 is connected with the RFID wireless identification receiver 21, the power measuring unit 22 and the power control unit 23 of one of the receptacles 2. Each hub 31 is connected to one of the control circuits 3 and a local area network (LAN) 32 for each control circuit 3 to transmit power information of each one of the at least one electric appliances 1 connected with a corresponding power socket 20 to a remote control center 4 and for the remote control center 4 to selectively switch on or off the at least one electric appliance 1.
Given the intelligent power supply system, product information and power consumption information of each electric appliance 1 connected to a corresponding power socket 20 within the region A can be monitored and powered on or off by a command sent from the remote control center 4 to the power socket 20.
To implement the intelligent power supply system, a wireless transmission technique, such as Zigbee, Z-WAVE, Bluetooth or the like, can be employed. When implemented with Zigbee, a communication protocol defined in certain layer of an interoperable smart energy standard can be configured in a preset user-defined application stack area of an interoperable home automation standard. The intelligent power supply system can be built in compliance with the interoperable home automation standard to measure power consumption measurement, power on or off the electric appliance 1 connected to each controlled power socket 20, and provide a fine-tunable dimmer to control power supplied to the controlled power socket in the region A.
