Abstract
The utility model discloses an electric meter recording system for carrying out intelligent query and recording on electricity consumption for frequency conversion and preventing external disturbances, and the system is composed of a PLC (programmable logic controller), a touch screen, a smart electric meter, an AC (alternating current) contactor and a frequency converter; the electricity consumption is read in a mode of carrying out communication between the PLC and the smart electric meter, thereby changing the previous mode of recoding the electricity consumption through reading the meter manually; intelligent data recording and data query windows are set on a screen of the touch screen, thereby facilitating the queries of users; the smart electric meter is connected to a frequency conversion loop, so that the smart electric meter is started while the frequency converter is started, and because the smart electric meter has an individual timing function, the accuracy of the power consumption records is guaranteed; and the PLC monitors the operation state of the electric meter, and when a phenomenon of communication fault or unbalance three phase circuit occurs, the PLC locks the output of the frequency converter. The electric meter recording system is applicable to various occasions on which a frequency converter is adopted and the electricity consumption for frequency conversion is calculated individually, so that the electric meter recording system has the advantage of great practicality.
Description
Affiliated technical field
The utility model relates to a kind of frequency conversion power consumption intelligence inquire, record and anti-external disturbance ammeter register system; Especially adopting touch-screen is display interface; Can make things convenient for user inquiring frequency conversion power consumption; The working time that on touch-screen, shows simultaneously frequency converter and ammeter respectively, the accuracy of assurance frequency conversion power consumption, PLC can export according to ammeter running status control of conversion device.
Background technology
At present, most power consumption calculates the mode that all adopts manual metering, has not only increased manpower, and the mistake that also inevitably can produce record simultaneously makes power consumption not meet the loss that actual amount causes both sides.In the occasion that frequency converter is used, the most calculating of frequency conversion power consumption and power frequency power consumption has caused inconvenience to the calculating of frequency conversion power consumption; Simultaneously, in the part occasion, because partly cause causes the ammeter cisco unity malfunction, this makes the power consumption can not accurate recording, and supplier of electricity has been caused very big economic loss.
Summary of the invention
For overcome the big and data recording of manual metering labour intensity exist ammeter that error, external cause cause can not accurate recording etc. problem, the utility model provides a kind of frequency conversion power consumption intelligence inquire, record and anti-external disturbance ammeter register system.This system can realize accurately calculating the frequency conversion power consumption and power consumption intelligence writes down, the function of inquiry.
The utility model solves the technical scheme that its technical matters adopted: this system is made up of frequency converter, PLC, touch-screen, intelligent electric meter, A.C. contactor summation current transformer, and intelligent electric meter is connected between contactor and the frequency converter inlet wire side.Adopt and support the intelligent electric meter of MODBUS communication protocol to be connected to the acquisition module of frequency conversion loop as electric weight; PLC reads the data in the ammeter in real time as communication main station; Touch-screen communicates with PLC as display interface, record and storage ammeter data, and edit the inquiry that corresponding picture is realized electric weight in certain period; After ammeter starts, on touch-screen, open clocking capability, and the timing variable is stored, and read single-conversion device accumulated running time at set intervals and be presented on the touch-screen through PLC; Ammeter and frequency converter realize that through electric steering logic promptly when starting frequency converter, ammeter also starts simultaneously with opening with closing; When the ammeter phase shortage or when communication failure occurring, can on touch-screen, show fault and block frequency converter output.
The advantage of the utility model: can write down the frequency conversion power consumption automatically, and can conveniently read the power consumption of certain period through touch-screen; Simultaneously, ammeter and frequency converter are taked with opening with closing and separate timing mode, and; The working time that on touch-screen, shows the two; The two compares, and can prevent the go wrong error logging of the frequency conversion power consumption that causes of ammeter, and PLC can export according to ammeter running status control of conversion device.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Accompanying drawing is the utility model system construction drawing.
The explanation of accompanying drawing sign:
1 frequency converter, 2 intelligent electric meter 3PLC
4 touch-screens, 5 A.C. contactors
Embodiment
Embodiment 1: A.C. contactor is closed, and frequency converter powers on, and starts intelligent electric meter and PLC simultaneously; PLC reads the ammeter running status, if normal, then control of conversion device output.Ammeter is gathered frequency conversion loop power consumption, through the MODBUS agreement record data is delivered to PLC then, and data are handled through PLC and delivered to touch-screen; In touch-screen, ammeter data writes down once at set intervals; Be provided with power consumption time period inquiry picture in the touch-screen, only need be during use in the time period that the input of picture appropriate section will be inquired about, touch-screen will demonstrate the power consumption of this time period.PLC program set inside communications status position, if PLC communicates by letter with ammeter normally, mode bit is 1, ammeter timing variable continues timing on original basis simultaneously; If communication failure, state position 0, the variable of timing simultaneously stops timing, and preserves the present timing time.PLC reads the accumulated running time of frequency converter inside, and on touch-screen, shows; PLC reads the running status of ammeter when communicating by letter with ammeter, when ammeter power down or input imbalance, PLC blocks frequency converter output.
Claims (2)
1. a frequency conversion power consumption intelligence inquire, record and anti-external disturbance ammeter register system; It is characterized in that: this system is made up of frequency converter, PLC, touch-screen, intelligent electric meter, A.C. contactor summation current transformer, and intelligent electric meter is connected between contactor and the frequency converter inlet wire side.
