ELECTRIC ENERGY METERING TERMINAL AND ELECTRICAL FIRE MONITORING METHOD

Номер: WO2016115848A1
Автор: FAN, Wenxue
Принадлежит:

An electric energy metering terminal and an electrical fire monitoring method, comprising: a sampling unit, used for acquiring a leakage current on a load line of the electric energy metering terminal in real time by means of a high-precision residual current transformer (300); a determining unit, used for determining whether an electrical fire happens according to the leakage current on the load line acquired in real time (301); and a processing unit, used for controlling on and off of a circuit load by means of a preset switch according to the determining result indicating whether the electrical fire happens (302). By integrating a fire monitoring function into the electric energy metering terminal, an electrical fire can be prevented; by carrying out timely circuit on-off processing on a happening fire, the spreading speed of the electrical fire can be greatly reduced, safety guarantee of the rescue work is provided for fire extinguishment, and an electric shock incident in the fire ...

METHOD OF MANAGING PREPAID SMART MEASUREMENT AND CONTROL TERMINAL AND PREPAID SMART MEASUREMENT AND CONTROL TERMINAL UTILIZING SAME

Номер: WO2016201985A1
Автор: FAN, Wenxue
Принадлежит:

A method of managing a prepaid smart measurement and control terminal and a prepaid smart measurement and control terminal utilizing the same are disclosed. The terminal comprises a CPU interface (101), a memory (102), a keyboard input unit (103), and a processor (104). The CPU interface (101) is connected to a CPU card. The memory (102) is configured to store electricity management information. The keyboard input unit (103) is configured to receive first encoded information input via an external keyboard, wherein the first encoded information is configured to modify electricity information. The processor (104) is configured to modify, according to the first encoded information, the electricity management information in the memory, and store new electricity management information after the modification into the memory (102). When the CPU interface (101) is connected to the CPU card, the electricity management information after the modification is transmitted to the CPU card via the CPU ...
