Embodiment Construction

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the explanatory text.

[0049] The present invention provides an early warning method for electricity safety of an intelligent power distribution box. Firstly, an electric signal acquisition circuit is constructed to facilitate real-time monitoring of the electric signal on the line, and the monitoring result is transmitted to a remote terminal to realize remote monitoring. .

[0050] Such as Figure 1-2 As shown, the electrical signal acquisition circuit includes:

[0051] A plurality of voltage dividing resistors R5-R8 connected in series, the first said voltage dividing resistor R5 is connected to the incoming terminal of the fire wire, and the last said voltage dividing resistor R8 is connected to the non-inverting input terminal of a first comparator OP1, said first comparator The output...

Abstract

The invention discloses a power utilization safety early-warning method for an intelligent distribution box. The method comprises the steps of step 1, collecting a real-time current value I on the incoming line of the distribution box, and calculating a current effective value Ia; step 2, acquiring a real-time voltage value U on an incoming line of the distribution box, and calculating a voltage effective value Ua; step 3, setting an absolute threshold value of the real-time current value I, an absolute threshold value of the real-time voltage value U, an effective threshold value of the current effective value Ia and an effective threshold value of the voltage effective value Ua; step 4, carrying out overcurrent protection early-warning on the real-time current value I and the current effective value Ia, carrying out overcurrent protection when the real-time current value I or the current effective value Ia exceeds a corresponding threshold value, cutting off a power supply, and sending out early-warning; and step 5, performing bidirectional over-limit protection early-warning on the electric signal on the line. The technical problem that line fault early-warning is not in time issolved.

Description

technical field [0001] The invention relates to the technical field of intelligent power consumption monitoring, in particular to an early warning method for power consumption safety of an intelligent power distribution box. Background technique [0002] The Internet of Things technology has developed rapidly in the past ten years. As an important part of the new generation of information technology, the Internet of Things is the third wave of the world's information industry after computers and the Internet, and it has a tendency to gradually replace the traditional Internet.
