Abstract
The invention relates to the monitoring and measuring technology of residential electricity consumption safety, in particular to equipment aiming at carrying out intelligent monitoring and safety protection on residential electricity consumption safety, and discloses an intelligent power distribution security control terminal based on residential electricity consumption. The intelligent power distribution security control terminal is characterized by being capable of monitoring load current, residual current, voltage loss, overvoltage, over-current and other security conditions of a total user circuit and all branches, and setting intelligent power failure and switching off a power supply circuit according to a limiting value, and displaying alarm information. The equipment has a telecommunication capacity. According to the intelligent power distribution security control terminal provided by the invention, a small intelligent power distribution automation system is built for the power consumption of existing residential households, and therefore the safety and reliability can be improved, and the fire safety accidents caused by an electrical reason can be eliminated; furthermore, the system is capable of remotely controlling the power supply of all the branches, so as to realize the family energy efficiency management.
Description
Technical field
the present invention relates to monitoring and the measurement technology of residential electricity consumption safety, the equipment of intelligent monitoring is mainly carried out safely for residential electricity consumption, the security situation such as load current, residual current, decompression, overvoltage of this device energy monitor user ' total line and each branch road, and intelligent power-off is set according to limit value and closes, and there is the ability of telemanagement, guarantee the safe and reliable of residential electricity consumption.
Background technology
all have a little distribution box in current most of resident family, power line is divided into several branch road by the distribution box of this belt fuser and distributes to illumination, air-conditioning (electric heater), refrigerator and each room socket and power, because the household electrical appliances quantity such as present family air-conditioning, computer, electric heater, refrigerator are many, power consumption is large, therefore often occurs excess load and jumps electric problem.
a lot of old residential building, because the electric wire be embedded in body of wall is aging, easy generation wire single phase ground fault, as single-phase wire break, wire overlap joint earth electrode, and wherein most of phenomenon of the failure is hidden, this is because the insulation resistance of the insulating barrier of wire is defective, due to the too small generation leakage current of insulation resistance.Concentrate inflow geodetic point (earth electrode) that high heat just can occur at leakage current, once have combustibles at inflow geodetic point, just can produce burning through high temperature action.The leakage current of wire is generally mA level, and the overcurrent protection (overload protection and short-circuit protection) of circuit action cannot play protective effect.Fire prevention and electrical safety problems can be caused, if house lead in zero line burns out, voltage instability easily causes electrical equipment in resident family to be burnt.
Summary of the invention
the present invention monitors the total house lead in of user, carries out Real-time Collection, and can arrange alarm limits to every parameter to all electric parameters of each branch road circuit, restriction is exceeded to load, leakage current numerical value exceedes restriction, can report to the police, and can automatic shutdown circuit.
the present invention adopts touch screen to carry out man-machine interface operation, is realized and the communicating and control to each branch road measurement module and overall measurement module of touch screen by MCU.
the present invention adopts manganese copper diverter to sample each branch current, and shunt maximum current to 60 peaces, then through resistance current limliting, capacitor filtering, jayrator, finally can send into metering units.
the present invention receives the signal of multichannel shunt by MCU P1 mouth simultaneously simultaneously, and to collection current data amount, and total electricity that is cumulative and computation chip is compared, and error is as being greater than 2%, and this sends warning message.
the present invention adopts single-phase double-current sampling electric energy computation chip HG7211 to monitor way circuit, and obtains all electric parameters, comprises electric current, voltage, active power, apparent power, phase angle, frequency.
the present invention adopts residual current detection ability, can prevent person electric shock, electrical fire and electric equipment from damaging.
the present invention adopts magnetic latching relay to carry out automatic switch control to each branch road respectively, and magnetic latching relay volume is little, reliability is high, cut off current capacity by force, and power consumption is low.
Accompanying drawing explanation
fig. 1 is theory diagram of the present invention.
Embodiment
the specific embodiment of the present invention:
1, measuring unit: by completing test and the storage of all electric parameters to the sampling of resident's house lead in power line, and the parameters such as electric current, voltage, power, electric energy, frequency are sent to MCU control unit;
2, touch screen is man-machine interface, and realizing various limit value must be arranged, the setting of warning message, and reads various electricity consumption data;
3, current data Acquisition Circuit, the current sampling value of each branch road enters into the different I/O port of MCU control unit by A/D conversion, each branch current and house lead in voltage multiplication obtain power and power consumption, and at any time by electric current and limit value comparison, finding that there is overage will report to the police;
4, residual current protecting function, the power line zero of house lead in, live wire are penetrated a current transformer by the present invention simultaneously, detect residual current size, normal condition current transformer current transformer does not respond to output, and when leaking electricity, live wire and ground wire form loop, now in zero line not or have very small area analysis, this electric current and the specified protective current that arranges of MCU control unit compare, and exceeding limit value will send open command, and display alarm information;
5, MCU control unit is core, mainly carry out the process of branch current data analysis, control magnetic latching relay and carry out load management, carry out necessary monitoring and energy conservation simultaneously to total house lead in power line and branch road, the instruction that reception touch screen sends simultaneously realizes optimum configurations;
6, communication unit: mainly by receiving the user instruction come by WIFI network, warning message being sent to user automatically, and realizes the access of user to family distribution situation, as situations such as load condition, energy resource consumption, voltage fluctuations.The present invention is that existing residential households electricity consumption establishes intelligent power distribution automated system, improve safe and reliable level, eliminate the security against fire accident because electric reason causes, can also the power supply of each branch road of Long-distance Control by this system, and then realize family's energy efficiency management.
