Description
The present invention relates to a kind of electric energy metering controller, the oil pumper electric energy measurement of particularly suitable field work.For a long time, the oil pumper electric energy measurement is blank at home always, therefore how convenient, fast measurement oil pumper electric energy is the weak link in producing always, power consumption accounts for 30% of cost for oil production at present, in order to reduce cost, the power consumption that recovers the oil must be lowered, the measurement of the electric energy of oil pumper is the indispensable means that reduce the oil pumper power consumption.
The purpose of this invention is to provide a kind of device for measurement of electrical energy that can be directly installed on the pumping-unit motor casing, check meter with telepilot, be with liquid crystal display on the meter-copy device, it is efficient and convenient to check meter, and does not expose gauge outfit, is fit to field work.
The present invention realizes by following scheme: adopt current sensor, voltage sensor, to oil pumper operating voltage, current sample, measure with electric energy measure chip, and deliver to single-chip microcomputer and carry out computing, operation result is stored by the single-chip microcomputer internal storage.When transceiver receives meter reading instruction, after single-chip microcomputer is confirmed, the store memory accumulate can data be accessed, and the process transceiver is launched, the transceiver that transmits in the remote control meter-copy device receives, single-chip microcomputer in meter-copy device confirms, at the liquid crystal display displays number of checking meter, thereby finished the purpose of electric energy measurement.
The present invention has following advantage:
1. electric energy metering controller for oil pumping machine is directly installed on the motor case, and volume is little, totally-enclosed, safe and reliable, prevents artificial destruction.
2. carry out straighforward operation, liquid crystal display, more quick and easy than meter sense.Get back to indoor playback and can directly print, deposit, reduce the complicate statistics error, increase work efficiency.
3. show the electric energy number on meter-copy device, it is fragile to have solved common electric energy meter field work, moistureproof, dustproof is difficult, makes electric energy measurement more reliable.
Electric energy metering controller for oil pumping machine have that oil pumper " leaves ", " pass " control, and defencive functions such as phase shortage, overload are arranged.Collection control, protection, three kinds of functions of measurement are one, have reduced the outfit of equipment cost.
5. electric energy metering controller energy measurement ascending current, centrifugal current, average current with the trouble of split-core type meter measurement above-mentioned parameter, are increased work efficiency when avoiding the oil pumper balancing.Now in conjunction with the embodiments the present invention is further described.
Fig. 1 is principle of the invention figure.Fig. 2 is meter control box structure figure of the present invention.Fig. 3 is a remote control meter-copy device schematic diagram of the present invention.
Electric energy metering controller for oil pumping machine of the present invention is as shown in Figure 1: be made up of two parts: a part is remote control meter-copy device (1), another part is the meter control case (6) that is directly installed on the pumping-unit motor casing, and current sensor (8), voltage sensor (7), controller (5), electric energy measure chip (2), single-chip microcomputer (3), transceiver (4) are equipped with in meter control case (6) inside.Current sensor (8), voltage sensor (7), link to each other with electric energy measure chip (2), electric energy measure chip (2), single-chip microcomputer (3) transceiver (4) link to each other successively, and single-chip microcomputer (3) links to each other with controller (5).
Present embodiment meter control box structure figure is made up of case lid, base plate as shown in Figure 2.Current sensor (8), voltage sensor (7), controller (5), single-chip microcomputer (3), electric energy measure chip (2) are installed on the base plate, on the base plate 4 mounting holes are arranged simultaneously, link to each other with the casing of oil pumper with bolt, side of base plate is a panel, three three-phase supply entrance holes and transceiver signal transmission hole are arranged on the panel.
Remote control meter-copy device principle is as shown in Figure 3: meter-copy device (1) by transceiver (01), single-chip microcomputer (02), display (03), signal output device (04) and button open (050), close (051), manually (052), automatically (053), increase (054), reduce (055), electric energy measurement (056), fault explanation (057), parameter declaration (058), parameter adjustment (059), running current (060), standby (061) ten two button form.Transceiver (01), single-chip microcomputer (02), signal output part (04) link to each other successively, and single-chip microcomputer (02) links to each other with display (03), and button (050～061) links to each other with single-chip microcomputer 02.Start, stop key are used to control start, the shutdown of oil pumper; automatic key explanation oil pumper is in automatic mode, manipulated key explanation oil pumper is in manual work state, parameter declaration key in order to the running parameter of oil pumper to be described: as protective current, delay time, accumulative total working time, ascending current, centrifugal current, the average current of running current key text oil pumper.The parameter adjustment key is used for the protective current size of oil pumper, the adjustment of the length of delay time.The fault that fault explanation key is used to illustrate oil pumper as: phase shortage, overload etc., electric energy measurement key are used to measure the power consumption of oil pumper accumulative total.So just reaching measurement, control, protection, three kinds of functions is the purpose of one.
The start course of work: by " opening " key of remote control meter-copy device, remote control meter-copy device (1) sends start-up command, received by transceiver (4), after single-chip microcomputer (3) is confirmed, single-chip microcomputer sends instruction and makes controller (5) adhesive, pumping-unit motor must be established the beginning running by cable, current sensor (8), voltage sensor (7) just has signal output, deliver to electric energy measure chip (2) and begin counting, and data are delivered to single-chip microcomputer (3) internal storage store, when by remote control meter-copy device (1) electric energy measurement key, remote control meter-copy device (1) sends copies instruction, is received by transceiver (4), after single-chip microcomputer (3) is confirmed, the data of storage inside are launched by transceiver (4), received by the transceiver of remote control meter-copy device (1) (01), after single-chip microcomputer (02) is confirmed, upward show the number of checking meter at display (03), finish the process of electric energy measurement, the data of remote control meter-copy device storage can supply back indoor back to print or deposit.
