Abstract
The invention relates to a Bluetooth electric energy meter which comprises an electric energy measurement loop, a controller, a display circuit, a power circuit and the like. The Bluetooth electric energy meter is characterized in that a Bluetooth module is further connected onto the controller. The electric energy measurement loop can transfer measured metering data to the controller, and then the controllers transfers the metering data to the Bluetooth module and enables the Bluetooth module to sends the metering data out, so that receiving of a meter reading device is facilitated. The Bluetooth electric energy meter utilizes a Bluetooth technology to perform wireless transmission of the electric energy metering data, so that a meter reading worker can conveniently use a special device to receive the data, meter reading errors and the meter reading difficulty caused by influences of the service level and surrounding environments can be avoided, the meter reading accuracy is ensured, and the meter reading work efficiency is also improved.
Description
Technical field
The present invention relates to a kind of electric power meter, particularly a kind of bluetooth electric energy meter that can wirelessly transmitting electrical energy continuous data.
Background technology
The mode that at present meter reading personnel of electric company obtains electric energy measurement data mainly contains three kinds: (1) manual metering, (2) IC-card (3) remote automatic meter reading of checking meter.In these modes, remote automatic meter reading is because its data transmission is accurate, save the advantages such as manpower, the concentrated urban subscriber of table meter and capacity, in the user of 100kVA, be used widely, but still there is following problem: remote meter reading needs extra concentrator and the GPRS remote transmission device installed, the annual larger data transmission expense of Xu Xiang telecommunications company's payment amount; The table of remote meter reading is counted signal between 485 interfaces and concentrator and is transmitted because being subject to electromagnetic interference (EMI) to affect reliability.Manual metering mode is affected by meter reading personnel's professional skill, surrounding enviroment etc., often there will be the mistake of checking meter, registration to read difficulty, checking meter wastes time and energy and the problems such as security incident easily occur.IC-card is often checked meter and can is difficult to carry out because the problems such as table meter position is improper make to check meter.
?
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and utilize bluetooth device transmissions electric energy measurement data, can avoid the bluetooth electric energy meter of artificial, IC-card and remote automatic meter reading Shortcomings.
The object of the present invention is achieved like this: a kind of bluetooth electric energy meter, comprise electric energy measurement loop, controller, display circuit, power circuit etc., and it is characterized in that being also connected with bluetooth module on controller.
Electric energy measurement loop can be transferred to controller by the continuous data recording, then by controller, is sent to bluetooth module and controlled bluetooth module continuous data is sent, so that kilowatt meter recorder receives.
The invention has the advantages that: utilize Bluetooth technology that electric energy measurement data is carried out to wireless transmission, so that meter reading personnel uses specialized equipment to carry out data receiver, thereby can avoid check meter mistake and the difficulty of checking meter that because of professional skill, surrounding enviroment impact, cause, both guarantee the accuracy of checking meter, also improved the work efficiency of checking meter.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, electric energy measurement of the present invention loop is is mainly connected and composed by electric energy computation chip ADE, current filtering circuit 1, voltage filter circuit 2, load current converts suitable current signal to through current filtering circuit 1, enters current channel, i.e. the V1P of electric energy computation chip, V1N pin; Load voltage passes through after voltage sensor step-down, then enters voltage channel by voltage filter circuit 2, i.e. the V2P of electric energy computation chip, V2N pin; The elements such as the resistance in current filtering circuit 1 and voltage filter circuit 2, electric capacity mainly play filtering and protective effect, voltage signal is after diode D5, D6 and capacitor C 15, C16, through voltage transitions chip U4, by 5V voltage transitions, be 3V voltage, be sent to the RESET pin of electric energy measure chip, input voltage is monitored; 3 is the clock loop of electric energy measure chip.After electric energy measure chip received current and voltage signal, through its inner multiplier, signal is converted to power data, again by inner numeral--frequency converter is converted to high-frequency pulse signal, high-frequency pulse signal exports the INTO pin of controller MCU to by light-power conversion circuit 4, controller is single-chip microcomputer, it receives after power data, by plug-in, calculate electric quantity data, and pass through RTX, TXD pin sends data to bluetooth module BLK1, blue die block receives after data, instruction by controller sends data-signal, for blue tooth meter recorder, receive.The P21 of controller, P22 pin are also sent to electric energy measurement data storage chip CP1, it are stored, in order to back up current data under the unexpected situations such as power failure; Controller is also transferred to display module P1 by P0.0-P0.7 pin by energy data, and selects by fill order, reading and writing operation and the register of P2.5, P2.6 and P2.7 pin control display module.The 5th, the function reset loop of controller, presses the button after switch S 1, and controller restarts electric energy statistical work; The 6th, the clock loop of controller; The 7th, the DC power supply circuit of whole electric energy meter, changes 5V DC voltage by transformer and rectification circuit by 220V alternating voltage, then by 5V voltage transitions, is 3.3V voltage through voltage transitions chip U1, as the direct supply of each electronic component.
