Current Control Device and management device

Abstract

The invention discloses a current control device and a management device. The current control device includes a power connection unit, a primary current control unit and a primary power supply unit. The primary current control unit is coupled between the power connection unit and the primary power supply unit to control whether electricity is conducted between the power connection unit and the primary power supply unit. The primary current control unit includes a primary power switch, a current detection element and a microprocessor. The current detection element is utilized to measure an operation current value (OCV) transmitted from the power connection unit to the primary power supply unit and compares the operation current value (RCV) to the operation current value. When the comparison result is abnormal, a countdown period (CP) starts. If the operation current value (OCV) remains abnormal during the countdown period (CP), the primary power switch is OFF to cut off electricity supplied from the power connection unit to the primary power supply unit. Thus the energy consumption is prevented when an appliance is not in use or in long standby or in abnormal operation, and the efficiency of the safety utilization of electric power supply is improved.

Description

technical field [0001] The invention relates to a current detection and management device, in particular to a current detection and management device which controls and manages the power supply of electrical appliances by detecting the working current state, so as to avoid idle electrical appliances from consuming electric energy in standby. Background technique [0002] Generally, as long as the electrical appliances are connected to the power supply, even if they are not turned on or unplugged, they are in a standby state, and there will be a small current passing through, causing power consumption, which will cause considerable waste of power over a long period of time. The result is not only costly. It will also increase the emission of carbon dioxide, increase the crisis of global warming, and threaten the human living environment. From a statistical point of view, if a family has dozens of unnecessary electrical appliances wasting, tens of millions of households around...

Problems solved by technology

[0002] Generally, as long as the electrical appliances are connected to the power supply, even if they are not turned on or unplugged, they are in a standby state, and there will be a small current passing through, causing power consumption, which will cause considerable waste of power over a long period of time. The result is not only costly. It will also increase carbon dioxide emissions, increase the global warming crisis, and threaten the human living environment

From a statistical point of view, if a family has dozens of unnecessary electrical appliances wasting, tens of millions of households around the world will have hundreds of millions of unnecessary power supplies continuing to waste, and the situation of energy waste is considerable; It can be seen that the lack of energy waste caused by idle electrical appliances connected to the power supply obviously needs to be actively studied and solved.

[0003] In the prior art, Taiwan Patent Application No. 098143628 "Energy Saving Socket" B, although low power consumption can be used to power off the jack module, but in practical application, it does not provide flexible and adjustable buffer time. Inconvenience in use; another Taiwan patent application No. 099213855 "intelligent energy-saving plug" case B also does not provide elastic and adjustable buffer time, causing inconvenience in use; Taiwan patent application No. 098220768, "current management For device "B", testing idle power consumption requires both a voltage sensor and a current sensor at the same time, and the cost is relatively high, which increases the difficulty of implementation; Taiwan Patent Application No. 098209298 "An Energy-saving Power Distributor" B requires additional use for comparison circuit, which increases the cost of the circuit; and in Taiwan Patent Application No. 09911714, "electrical device power-off device" B case, the starting unit will not only start the power supply unit, but also start the controlled circuit breaking unit, causing inconvenience in application
