Technical field
The utility model relates to a kind of device status monitoring and error correction device.
Background technology
Electric energy metrical simulator (hereinafter referred to as simulator) is usually by power supply unit, adjustment unit, protecting control unit, the compositions such as display unit, on two or three different operating surfaces of simulator, be separately installed with one or two real training electric energy meters, when simulator normally works, the unlatching to simulator is completed by a computer for controlling, the setting of electrical quantity, adjustment with the control and operation such as to close down, simulator can simulate the various different field conditions of electric power meter, for technician, the professional training of the professionals such as electrician, comprise: high, the analysis of low-voltage Watt-hour meter false wiring and correction, high, the field calibration exercise of low-voltage Watt-hour meter, the projects such as the pressure fall-off test of voltage secondary circuit, at present in the teaching of electric system, be widely used in training and Skill Competition.
In the use procedure of such simulator, there is system stability and the bad problem of reliability sometimes, be exactly that the various parameters set by computer for controlling occur drift at the run duration of simulator and restore back to zero specifically, and the display of computer for controlling is still the problem of former setting value, especially wiring analysis project, if the setting value of power factor angle departs from former setting value at run duration, or recovery back to zero, add the output of simulator and the measured deviation of testing tool, operator will make the judgement different resolutely in nature from former proposition, once there is this phenomenon, follow-up phasor graph drawing is with power expression and calculate then meaningless, this fault state is once occur, light then teaching and training effect can be affected, heavy then directly can affect result of the match, cause unnecessary dispute and loss.Appearance due to this phenomenon of the failure has very large uncertainty, belongs to the soft fault of system, is therefore difficult to solve this problem from analogue system self aspect.
Utility model content
The utility model, in order to solve the problem, discloses a kind of device status monitoring and error correction device, and this device directly utilizes the computer for controlling of emulator as controller; Utilize the real training electric energy meter on emulator as the feedback carrier of emulator output parameter, controller is by this electric energy meter, the electrical quantity that real-time reading emulator finally exports, and compare with the former setting value of computer for controlling, depart from setting value once discovery and exceed setting value, then send warning.
To achieve these goals, the utility model adopts following technical scheme:
A kind of device status monitoring and error correction device, comprise controller, electric energy meter, audible-visual annunciator, and wherein, controller connects electric energy meter, and electric energy meter is arranged on emulator, and audible-visual annunciator is connected with controller; Controller receives the setting voltage of emulator, electric current and power factor value parameter, the controller also voltage of reading power meters Real-time Feedback, electric current and power factor value parameter simultaneously; Controller is by setting value compared with the similar parameter of the feedback of electric energy meter, and send a signal to audible-visual annunciator when fiducial value is greater than setting value, audible-visual annunciator is reported to the police.
Described controller can be the computer for controlling of emulator.
Described audible-visual annunciator is LTE--1101J type alarm.
Described electric energy meter is DSSD188 type electric energy meter.
Described emulator is WT-F24 type connection box of electric energy meter simulator.

Described electric energy meter is multiple, and the electric energy meter had more is redundancy electric energy meter.
The beneficial effects of the utility model are:
(1) controller is by electric energy meter used on emulator, monitors in real time the setup parameter of emulator computer for controlling, guarantees there be the stable and reliable of emulator, is conducive to improving teaching, training and contest quality;
(2) be provided with audible-visual annunciator, when occurring relatively large deviation occurs between the output valve and setting value of emulator and alarm, contribute to Timeliness coverage problem;
(3) utilize the computer for controlling of emulator as controller; Utilize real training electric energy meter on emulator as feedback carrier, ingeniously utilize existing equipment, economy is high.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model;
Wherein, 1, controller, 2, electric energy meter, 3, audible-visual annunciator, 4, emulator.
Embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, by controller 1, two electric energy meters 2, audible-visual annunciator 3 and emulator 4 form, and controller 1 is wherein same machine with the computer for controlling of simulator; The DSSD188 type electric energy meter that electric energy meter is; Audible-visual annunciator 3 is LTE--1101J type alarm; Emulator 4 is WT-F24 type connection box of electric energy meter emulator.
Controller 1 connects electric energy meter 2 by 485 lines, and be connected with emulator 4 by USB interface, audible-visual annunciator 3 is arranged on emulator 4 simultaneously.
Below in conjunction with Fig. 1, its principle of work and implementation process are described.
The course of work of the present utility model is: when emulator 4 enters normal operating conditions, the voltage that computer for controlling is set, electric current and power factor value are transferred to controller simultaneously, the electric energy meter 2 of controller by connecting, constantly read the output parameter of emulator 4, and compare in real time with the setting value of emulator, numerical bias both finding exceedes setting range, even controller 1 sends alarm command, after instruction received by audible-visual annunciator 3, signal can be sent, the relevant personnel are reminded to examine, timely correction, avoid causing unnecessary dispute.
