Description
Technical field
The utility model belongs to a kind of intelligent electronic electric energy meter.
Background technology
Present resident's electric energy meter has obtained significant progress, develops from single household mechanical type ammeter to have infrared copy meter system, the IC-card kilowatt meter reading-out system that numeral shows, up-to-date intelligent electric meter with the many families demonstration of single table.But because the restriction of communication modes, cause user data can only one-way transmission to administrative center, and the corresponding information at center does not embody on electric supply meter, the electricity consumption behavior that administrative center can't limited subscriber, the function that not have identification and limit for the malice electricity consumption of user's overload.
Summary of the invention
The purpose of this utility model provides a kind of electronic electric energy meter, has the electrical appliance recognition function, the malice electricity consumption of limited subscriber.
The technical scheme that addresses the above problem is: in the control relay circuit, the communication interface P5.2 of microprocessor MCU 1 connects the data communication line of network system; The P2.0 of microprocessor MCU 1～P2.3 pin connects 11 pin of 4 control chips 2 respectively, is the chip selection signal port of control chip 2;
3,7 pin of chip for driving 3 link to each other with 19 pin of 2 relay control chips 2 respectively, by control chip 2 chip for driving 3 are produced and are switched on or switched off signal, 1,10 pin ground connection of control chip 2; 2～9 pin of control chip 2 are connected with D0～D7 of microprocessor MCU 1;
The terminals of relay 4 link to each other with subscriber's drop, with connecting and disconnecting user's power supply; 1,2 pin of relay 4 link to each other with 5,1 pin of chip for driving 3, produce the actuating signal of relay 4 by chip for driving 3;
The data port D0 of bus driver chip 5～D7 links to each other with the P7 mouth of microprocessor MCU 1, finishes image data after the processing and the transmission between the microprocessor MCU with this; The 10th pin ground connection of bus driver chip 5,20 pin connect+the 5V power supply;
Principle of work of the present utility model is: the communication interface of this ammeter is connected with the data communication line of automatic system, can carry out exchanges data by network service and Automatic meter reading system: automatic system can be sent command information to the single-chip microcomputer of electric energy meter, also can directly read ammeter data from communication interface.Suddenly increase when surpassing limit value when ammeter detects user power utilization amount moment, microprocessor MCU will send control signal and be used for control and disconnect this family relay, and its electricity consumption behavior of warning user is undesirable.After a few minutes of cutting off the power supply, microprocessor MCU restores electricity to this user automatically; If user's malice electricity consumption behavior surpasses time several of setting, then ammeter is thoroughly to this user's outage, to prevent to continue the generation of malice electricity consumption behavior.
Compare with existing electronic electric energy meter, the beneficial effects of the utility model are: the function that is provided with identification and restriction for the malice electricity consumption of overload.Load when the user has powerful electrical appliance, microprocessor MCU cuts off the power supply with regard to pilot relay, after the user removes high-power electric appliance, after 5 seconds that set, restore electricity again automatically, if above after the predefined number of times 5 times, and then thoroughly outage.Thorough like this malice electricity consumption of having stopped the user.

Embodiment
The model of the main modular that the utility model adopts:
Microprocessor MCU chip model C8051F020; Relay control chip 2 model 74LS573; Relay chip for driving 3 model BL8023; Relay 4 model BST902; Bus driver chip 5 model 74ls244; Photoisolator 6 model TLP521-4; Electric energy computation chip 7 model ADE7755.
Acquisition module adopts the collection of C8051F020 expansion ADE7755 realization ammeter electric weight, microprocessor MCU in the ammeter
Control center is handled and sent to image data manage control concentratedly.Control signal is detected and sent in control center to user's dump energy; By the data communication line microprocessor MCU is sent control information.
Present embodiment is established 4 control chips 2 altogether.Each relay chip for driving 3 is connected 3, the 7 pin realization control of chip for driving 3 by 19 pin of 2 control chips 2, the input pin 2～9 of control chip 2 is connected with microprocessor MCU data port D0～D7, output pin 19 links to each other with chip for driving 3, with this drive signal as pilot relay 4, when the control pin 1,5 of chip for driving 3 high and low level occurs respectively, relay 4 will produce corresponding action.
D0～D7 of microprocessor MCU is as data port, is used for receiving and transmit the data between microprocessor MCU and the peripheral hardware.The P2.0 of microprocessor MCU～P2.3 pin connects 11 pin of 4 control chips 2 respectively, chip selection signal port for control chip 2, be used for the gating control chip, by microprocessor MCU difference constantly gating control chip 2 realize the different level signal of control pin output of chip for driving 3.4,8 pin of chip for driving 3 connect the 12V power supply.
As shown in Figure 2, microprocessor MCU is provided with P2.0～P2.3 totally 4 control ports, controls 4 control chips 2, may command 16 family ammeter users' electricity consumption.The quantity of the control port of microprocessor MCU and control chip 2 is determined according to number of users, each microprocessor MCU may command user 1～48 family.In native system, electric energy acquisition chip 7 is passed to microprocessor MCU1 after the user's electric quantity data that collects is transformed through electric isolator chip 6, microprocessor MCU1 judges according to the data that receive whether the user has malice electricity consumption behavior, if malice electricity consumption behavior is arranged then microprocessor MCU1 pilot relay control chip 2 sends the corresponding driving control signal to chip for driving 3, by the corresponding actions of chip for driving 3 pilot relays 4.
