Abstract
The utility model discloses a prepaid metering device, which comprises a current mutual inductor, a voltage mutual inductor, an electronic electric energy meter, an alarm, a circuit breaker, a GPRS intelligent terminal and a controller. The prepaid metering device is characterized in that the controller is respectively connected with the alarm, the circuit breaker, the GPRS intelligent terminal and the electronic electric energy meter; and the electronic electric energy meter is respectively connected with the current mutual inductor and the voltage mutual inductor. The prepaid metering device has the technical effects of being suitable for prepaid users of special metering or centralized metering with the transformer capacity less than 3150KVA, facilitating the user to query the electricity utilization information anytime and anywhere, reducing the arrear situations, needing not get close to watch the meter information and improving continuity and security of electricity utilization.
Description
Technical field
The utility model relates to a kind of measuring apparatus, relates in particular to a kind of prepayment metering device.
Background technology
2009, general requirement according to strong intelligent grid construction, guarantee that the intelligent grid construction specification advances in order, realize the overall goal of power consumer power information acquisition system construction " all standing, full collection, full pre-payment, two-way interaction ", functional configuration, type structure, performance index, communication protocol, safety certification, the method for inspection, construction and the operational management etc. of unified and standard power information acquisition system and main website, acquisition terminal, communication unit.On the basis of State Grid Corporation of China's " power consumer power information acquisition system study on construction " project achievement in research, sales department of State Grid Corporation of China tissue is used present situation to the construction of domestic and international acquisition system and is investigated and analyze, and abundant development in conjunction with technology such as the communication technology, microprocessor technology, manufacturing process, the Its Relevant Technology Standards of the domestic and international power information acquisition system of combing has been formulated " power consumer power information acquisition system " series standard comprehensively.
Traditional ammeter needs the meter reading personnel to make rounds to each other's home to copy to fetch data, clear out expense after, ask for to each family again, error is large, the statistical work amount is large.Artificial mistake is brought great inconvenience to power department and user, produces easily dispute between power department and user.
Summary of the invention
The purpose of this utility model is to provide a kind of prepayment metering device, take public GPRS mobile communications network as carrier, the prepayment metering device carries out information interaction by note and designated user cell-phone number, sends electricity consumption arrearage alarming short message to the designated user cell-phone number; And providing the data messages inquiries such as the residue electricity charge, energy information, electrical parameter to the designated user cell-phone number, the user can inquire about the electricity consumption situation at any time and any place.
The utility model is achieved like this, it comprises current transformer, voltage transformer (VT), electronic electric energy meter, alarm, isolating switch, GPRS intelligent terminal, controller, it is characterized in that controller connects respectively alarm, isolating switch, GPRS intelligent terminal and electronic electric energy meter, electronic electric energy meter connects respectively current transformer and voltage transformer (VT).
Single Chip Microcomputer (SCM) system analytical calculation user power utilization situation and pre-paying situation in the prepayment metering device when reaching alarm threshold value, then send electricity consumption arrearage alarming short message by the GPRS intelligent terminal to the designated user cell-phone number.When Single Chip Microcomputer (SCM) system was received user's short message enquiry by the GPRS intelligent terminal, Single Chip Microcomputer (SCM) system then provided the data SMSs such as the residue electricity charge, energy information, electrical parameter by the GPRS intelligent terminal to the designated user cell-phone number.
Technique effect of the present utility model is: be applicable in transformer capacity the 3150KVA following special change metering or centralized measure prepaid user, make things convenient for the user to inquire about power information whenever and wherever possible, reduce the arrearage situation, need not closely watch ammeter information, improve continuity and the security of electricity consumption.
Description of drawings
Fig. 1 is functional-block diagram of the present utility model.
In the drawings, 1, current transformer 2, voltage transformer (VT) 3, electronic electric energy meter 4, alarm 5, isolating switch 6, GPRS intelligent terminal 7, controller.
Embodiment
As shown in Figure 1, the utility model is achieved like this, the utility model is achieved like this, controller 7 connect respectively alarm 4, isolating switch 5, GPRS intelligent terminal 6 and electronic electric energy meter 3, and electronic electric energy meter 3 connects respectively current transformer 1 and voltage transformer (VT) 2.By current transformer 1, voltage transformer (VT) 2 and electronic electric energy meter 3 the power consumer power consumption is converted to electric pulse; Controller 7 gathers electric pulse by the metering interface, and calculating, store power user power utilization amount; Management of power use unit pays the electricity charge by GPRS intelligent terminal 6 with the user and is transferred to sky controller 7; Controller 7 is analyzed and is compared the power consumer power consumption and pay electricity charge data, sends alerting signal or isolating switch cut-off signal by control interface, and reports to the police or the power failure note to the transmission of designated user cell-phone number by GPRS intelligent terminal 6; The designated user cell-phone number remains the data such as the electricity charge, energy information, electrical parameter by note to controller 7 inquiries.
