Abstract
An electric quantity metering device belongs to the active energy-saving field of energy resource real-time metering. The electric quantity metering device can be used for any electric quantity consumption point. The electric quantity metering device is similar to a power converter, one end of the metering device is connected with a detected electricity-consuming point, the other end of the metering device is connected with electricity-consuming equipment, a voltage sensor and a current sensor are arranged between the two ends, metered current and voltage are calculated into power or corresponding electric charge by a microprocessor, and a power carrier communication module built in the metering device can transmit the power or the electric charge parameters to a receiving device in the power carrier mode. Therefore, the electric quantity metering device realizes the purpose of remotely metering the electricity consumption of the electricity consumption point.
Description
Technical field
The utility model relates to a kind of electric quantity metering device, belongs to the active energy-saving field of energy real time measure.
Background technology
Present electric quantity metering device mainly is the total amount metering that is used for electric weight, is the total amount metering on temporal total amount and the space.That is, normally measure the metering of the power consumption total amount of the electricity consumption point in the spaces in a period of time, whole.Present meticulous day by day along with energy-saving and emission-reduction and environmental protection requirement, to energy process detect requirement with monitoring at any time can realize be in time real-time transient state, to be that each electricity consumption point is independent spatially measure.But traditional electric quantity metering device all can't satisfy above-mentioned requirements, more can't supervise consumer individual initiatively to carry out energy conservation through behavior.
Summary of the invention
Say on the subordinate act science that people's behavior generally has two kinds of active and passive-types, also be divided into active and passive-type in energy-saving field people's common behavior.
In order to solve the problem that above-mentioned prior art exists; The utility model provides a kind of electric quantity metering device; Can be at all instantaneous power consumption of electricity consumption point metering; Make receiving trap can show the power consumption of each electricity consumption point, thereby let the user learn the electricity condition of using of present each electricity consumption point, electric quantity consumption is controlled in the measure of taking the initiative.
The utility model solves the technical scheme that its technical matters adopted:
A kind of electric quantity metering device uses the external form that is similar to power-supply adapter, comprising: a body; Body is provided with one and is installed on the current sensor coil of measuring electric current in the circuit, a voltage sensor that is installed on measuring voltage in the circuit, a microprocessor and a power carrier module; Body also is provided with a terminal A who is connected with tested electricity consumption point and a terminal B who is connected with consumer.Link to each other with tested electricity consumption point at terminal A, when terminal B linked to each other with consumer, voltage sensor recorded voltage, and the current sensor coil records current DC; Magnitude of voltage that records and current value calculate the performance number and the electricity charge through microprocessor, and this signal is input to the power carrier module, and the power carrier module is exported to receiving trap after with the modulation of performance number and electricity charge signal.
The electric quantity metering device of the utility model, the metering of transient state in real time in time spatially is the metering separately of each electricity consumption point.
The sensor technology that the electric quantity metering device of the utility model relates to, microprocessor technology, PLC technology all are proven technique, and the commercially produced product of forgiving its technology contents can be easy to buy, and therefore, the utility model implements very simple.
The beneficial effect of the utility model is:
Can the unit of access or the full socket place of family; On receiving trap, show the electric quantity consumption or the electricity charge consumption of each electricity consumption point in real time; Make the user can see the electric weight or the electricity charge that each electricity consumption point is consuming, thereby learn and how to take measures, avoid unnecessary waste.
In sum, this electric quantity metering device is made simple, with low cost, can make module and embed use in socket or the power supply box, also can embed in the Power conversion board and use.
Description of drawings
Fig. 1 is a kind of elementary diagram of electric quantity metering device.
Among the figure: the terminal A that 1, is connected, 2, the current sensor coil, 3, voltage sensor, 4, microprocessor, 5, the power carrier module, 6, the terminal B that is connected with consumer with electricity consumption point.
Embodiment
Specify the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the current sensor coil 2 of the utility model is enclosed within on the live wire, according to the difference of the rated current that flows through, different range gears is arranged.Voltage sensor 3 is across between live wire and zero line; The output of current sensor coil 2 and voltage sensor 3; Send into the input end of microprocessor 4 and carry out the analog digital conversion, microprocessor 4 connects live wire and zero line obtains working power, and program wherein calculates the power or the electricity charge according to the electric current and the voltage parameter of input; And with this signal output; Send into power carrier module 5, power carrier module 5 is modulated into carrier signal with this signal, and through with the live wire and being connected of zero line of power supply carrier signal is sent into power lead.
During installation, with the live wire and the zero line disconnection of electricity consumption point, the terminal A1 that is connected with electricity consumption point connects supply side, and the terminal B6 that is connected with consumer connects the electricity consumption side, thereby this electric quantity metering device is inserted.Reception is loaded with the device of power or electricity charge modulation signal, is connected on the power lead, from power lead the modulated carrier signal that contains power information and address information is received.
