Abstract
The utility model relates to a control instrument for circuits of pumping units, and is substantially a microcomputer-controlled pumping unit monitor & protector. Technical plan of the utility model is that three transformers are used to collect current and phase-missing analogues, a power transformer is used to collect voltage analogues, then the analogues are converted to digital signals through an A/D converter, the digital signals are sent to a CPU through data lines, and the CPU is outer connected with a data storage, a clock generator, an electronic monitor, a digital display, operation buttons and a protective relay. The outside of the CPU is also connected with a wireless transmitter & receiver and an indicator. The electronic monitor is a watchdog electronic monitor. The utility model is featured with high integrity, stable and reliable operation and convenient handling and data acquisition. The utility model can realize real-time monitoring and protection of current, voltage and phase of motors, real-time analyze, store, read and send operation data of motors, and effectively avoid damage to motors and power theft by others.
Description
One, technical field: the utility model relates to a kind of oil pumper circuit control instrument, specifically is microcomputer oil pumper monitoring and protection instrument.
Two, background technology: the circuit supervision instrument that is used for pumping-unit motor protection at present is primarily aimed at the normal operation of motor and raises the efficiency and carries out, as phase shortage, overvoltage, overcurrent, and converting operation or the like.The ubiquity function singleness of these protectors, independent component Welding Design are also damaged, the problem of poor reliability easily.For the demonstration of data, store, read powerless especially.
Three, summary of the invention: the purpose of this utility model is exactly the defective that exists at prior art, provides that a kind of height is integrated, perfect in shape and function, reliable microcomputer oil pumper monitoring and protection instrument.
Its technical scheme is: gather electric current, phase shortage analog quantity by three instrument transformers; gather voltage analog by power transformer; then through mould number converter convert digital signal to; insert central processing unit through data wire, be externally connected to data storage, clock generator, electronic monitor, nixie display, operation push-button and protection relay at central processing unit.Periphery at central processing unit also is connected with wireless transceiver, indicator light, and described electronic monitor is the house dog electronic monitor.Described operation push-button is provided with and selects phase, checks card ,+,-, → and be provided with, described central processing unit is the AMTBGA16 processor, described clock generator and house dog electronic monitor are the MAX826 watch-dogs, described data storage is the 93CC46A memory, described mould number converter be the 7109C transducer, described nixie display is made up of 74LS245 driver and charactron.
The utlity model has the characteristics of integrated level height, stable and reliable operation, handled easily and data read; realize the monitoring constantly and the protection of current of electric, voltage, phase place; simultaneously the motor service data is analyzed constantly, stores, read and sends, prevent that effectively other people from destroying and stealing the generation with electrical phenomena to motor.
Four, description of drawings: accompanying drawing is a schematic block circuit diagram of the present utility model.
Five, specific embodiment:
With reference to accompanying drawing, three instrument transformers are gathered electric current, phase shortage analog quantity, and power transformer is gathered voltage analog, then through the 7109C mould number converter convert digital signal to, insert the AMTBGA16 central processing unit through data wire.Be externally connected to 93CC46A data storage, MAX826 watch-dog, 74LS245 driver and SN410502 charactron, wireless transceiver, indicator light, operation push-button and protection relay at central processing unit.Wherein the MAX826 watch-dog has the double action of clock generator, electronic monitor.Operation push-button is provided with and selects phase, checks card ,+,-, → and button is set.
Operation principle is:
Microcomputer oil pumper monitoring and protection instrument; utilize three instrument transformers to gather electric current; the phase shortage analog quantity; utilize power transformer to gather voltage analog; convert digital signal to through the 7109C analog to digital converter then and read in central processing unit ATMBGA16 the inside through data wire; be presented on yard pipe through driver; relatively judge with set point then; in case determine phase shortage; electric current; overtension; cross low (but the setting of scope manual adjustment); the protection instrument will be controlled protection relay and cut off motor power; and various power-off times are stored in the corresponding memory cell of memory 93CC46A the inside respectively; one looks into after being equipped with; the central processing unit of protecting instrument simultaneously is by the check card switching of button of driver 74LS245 detecting; check card in case determine to patrol well person's button, the time that central processing unit will this moment is stored the corresponding memory cell of memory 93CC46A the inside, and control is simultaneously checked card glittering 2 seconds of indicator light as responding.Remote control is opened; the realization of shutdown; it is central processing unit ATMBGA16 reads wireless receiver by the wireless receiving plate state; the switching on and shutting down signal that utilizes wireless receiver to receive; implement switching on and shutting down control to motor; central processing unit in above work simultaneously, the state of monitoring and protecting instrument operation push-button constantly also is in case have people's button then come fill order according to the button program.
