Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the examples, but the protection scope of the present invention is not limited thereto.
[0027] The invention relates to an electrical fire early warning method, which includes the following steps.
[0028] Step 1: Set the sampling unit at the neutral line of the cable.
[0029] In the step 1, the sampling unit collects the instantaneous current and voltage at the neutral line of the cable.
[0030] Step 2: The sampling unit feeds back the power data to the control terminal.
[0031] In step 2, the power data includes vector values of instantaneous current and voltage.
[0032] The sampling unit also includes a temperature sensor, and when the temperature sensor is higher than a threshold value, the control terminal controls the current cable to be disconnected.
[0033] In the present invention, the power data obtained by sampling is used for subsequent analysis and identification...

The invention relates to an electrical fire early warning method. By setting a sampling unit at the neutral line of the cable, the power data is fed back to the control terminal by the sampling unit and input into the corresponding hierarchical identification network. The situation will be reported to the police. The present invention can comprehensively monitor the operation data of the electrical circuit, mainly consider factors such as zero line current, harmonics, and three-phase imbalance for detection, conduct on-site sampling through the sampling unit, and have low dependence on field equipment, and can feedback abnormalities in real time through the data output through the network According to the situation, realize the fire alarm and strive for the time for emergency rescue and disaster relief.
Description
technical field [0001] The present invention relates to the technical field of signaling device or calling device; instruction sending device; alarm device, and particularly relates to an electrical fire early warning method. Background technique [0002] With the development of the country's economy and technology and the improvement of people's living standards, fire protection systems are widely used in people's production and life. Among them, electrical fire warning is one of the most important parts of the fire protection system. [0003] In the existing technology, electrical fire safety products are mainly based on residual current for post-fire alarm, focusing on leakage monitoring, and the monitoring data is single, without considering many other important factors such as neutral current, harmonics, and three-phase imbalance. High dependence on on-site equipment requires manual intervention, poor real-time performance, no preventive effect, and delays the best time...
