The utility model discloses a to the detection of board main line electric current, can be effectual overflow the main line, lack looks, the signal early warning is carried out in the short circuit, guarantees when the trouble takes place, can very first time discovery and solve the problem, make trouble loss minimum.
Description
Technical field
The utility model belongs to Digit Control Machine Tool field, particularly relates to a kind of Digit Control Machine Tool early warning system.
Background technology
Digit Control Machine Tool is typical electromechanical integrated product, and be the main flow equipment of modern manufacturing industry, along with the develop rapidly of Numeric Control Technology, numerical control device spreads all over the world.Along with the generally use of Digit Control Machine Tool, the fault of Digit Control Machine Tool also increases sharply, and adds many manpower and financial resources to production and plant maintenance unit, even causes a serious accident and economic loss to user.
At present, three aspects are mainly concentrated on to the research of diagnosing faults of numerical control machine: machining process monitoring system, remote fault diagnosis and fault prediction system.On-site supervision and remote fault diagnosis are all indirectly infer fault by carrying out monitoring to cutting process, and fault prediction system mainly detects machine tool component, the running status of the systems such as hydraulic pressure, carries out fault pre-alarming at the scene.
The NC Circuits System relative complex of Digit Control Machine Tool, component is also many.Easily there is some situations about happening suddenly, such as overcurrent, phase shortage, short circuit etc. in machine operation process.If Digit Control Machine Tool does not arrange a special current detecting early warning system, these faults are often ignored by the very first time.If these faults can not find in the very first time and keep in repair in circuit, some important circuit component damage will be made.The more serious whole Digit Control Machine Tool that will make is paralysed.
Summary of the invention
The utility model provides a kind of Digit Control Machine Tool early warning system, is intended to solve Digit Control Machine Tool circuit main line in prior art and occurs the bursting problem such as overcurrent, phase shortage, short circuit and be do not know, thus runs the problem that Digit Control Machine Tool causes electrical equipment to damage further.
A kind of Digit Control Machine Tool early warning system, comprises detecting element, gathers judgment component, signal output element; Described detecting element is arranged on the main line of Digit Control Machine Tool circuit by battery main switch, be used for detecting electric current, when described collection judgment component judges that the electric current that detecting element detects is greater than or less than rated current thresholding, just send early warning signal by signal output element.
Further, described collection judgment component is power supply acquisition module, the rated current thresholding that described power supply acquisition module setting board runs, described power supply acquisition module makes early warning whether judgement after being compared by the size detecting electric current of detecting element and the rated current thresholding of setting.
Further, described signal output element is RS232 communicator, when described power supply acquisition module judges that detecting electric current is greater than or less than rated current thresholding, provides early warning signal by RS232 communicator.
Further, when described collection judgment component judge to detect electric current equal or in rated current domain value range time, Digit Control Machine Tool runs well, and does not send early warning signal.
Finally, described detecting element is current transformer, and described current transformer is arranged on main line by battery main switch.
The utility model is by a kind of Digit Control Machine Tool early warning system; realize the monitoring to whole numerically-controlled machine tool system electric current; serve the effect of monitoring and monitoring; thus lathe is played a very good protection, can effectively to main line overcurrent, phase shortage; signal early warning is carried out in short circuit; ensure that the very first time finds and deals with problems when fault occurs, make breakdown loss minimum.

Detailed description of the invention
Below with reference to accompanying drawing, specific implementation process of the present utility model is described in detail.
A kind of Digit Control Machine Tool early warning system, as shown in Figure 1, comprises detecting element, gathers judgment component, signal output element; Described detecting element is arranged on the main line of Digit Control Machine Tool circuit by battery main switch 5, be used for detecting rail current, when described collection judgment component judges that the electric current that detecting element detects is greater than or less than rated current thresholding, early warning signal is sent by signal output element, described early warning signal can be sound, light warning device, the red light such as glimmered, buzzer etc.
Concrete, described detecting element is current transformer 1, and described current transformer 1 is arranged on main line by battery main switch 5, is used for detecting electric current.Described collection judgment component is power supply acquisition module 2, described power supply acquisition module 2 can set the rated current thresholding that board runs, after described power supply acquisition module 2 is compared by the collection size detecting electric current of current transformer 1 and the board rated current thresholding of setting, make accurately correct judgement, described correct judgement is whether the electric current of the clear and definite trunk circuit of Digit Control Machine Tool is at present normal, if normal, then Digit Control Machine Tool normally runs; If abnormal, then send the operation of early warning signal or stopping Digit Control Machine Tool.
Described signal output element is RS232 communicator 3, when described power supply acquisition module 2 judges that detecting electric current is greater than or less than rated current thresholding, will by RS232 communicator (3) communication to Digit Control Machine Tool 4 one early warning signals, prompting operator has fault to produce, the operation of Digit Control Machine Tool should be stopped immediately, rerun after carrying out failture evacuation; When described power supply acquisition module 2 judge to detect electric current equal or in rated current domain value range time, board runs well, and does not send early warning signal.During start, when system detects power phase shortage or have large impact electric current, Digit Control Machine Tool 4 can not operate.
The Digit Control Machine Tool early warning system more than realized, is arranged on Digit Control Machine Tool, by the detection to main line system electric current, can effectively to main line overcurrent, and phase shortage, signal early warning is carried out in short circuit.Ensure when fault occurs, the very first time can find and deal with problems.Make breakdown loss minimum.
Above with reference to the accompanying drawings of preferred embodiment of the present utility model, not thereby limit to interest field of the present utility model.Those skilled in the art do not depart from any amendment done in scope of the present utility model and essence, equivalent replacement and improvement, all should within interest field of the present utility model.
