Abstract

Disclosed is a palm style maintenance and test device for low voltage electric power carrier instrument, wherein a central processing unit is connected with and controls a low voltage power carrier communication unit, a liquid crystal display screen and a user push button to finish on-site measurement and function arrangement for a device which adopts a low voltage power carrier communication interface in a palm type industrial insulating casing. The central processing unit finishes the control of the whole device, and supplies test projects needed by a corresponding measured device for users,the liquid crystal display screen displays needed information in an audio-visual mode, and meanwhile, complete push buttons required by users are distributed for finishing the input of on-site affairs. Maintainers can conveniently adopt low voltage power carrier as the instrument of a communication mode in on-site operation, such as user ammeters and the like.

Description

A kind of hand held that is used for the low-voltage power carrier instrument is safeguarded and testing apparatus

Affiliated technical field

The utility model relates to a kind of hand held portable field attending device, and by this equipment, the maintainer can operate the low-voltage power instrument easily at the scene, especially adopts the instrument of low-voltage power carrier as communication modes, as electric supply meter etc.

Background technology

At present, adopt low-voltage power carrier to obtain increasing application, particularly in the electric network reconstruction process, adopt power carrier communication, obtained increasing application owing to need not additionally to arrange communication cable as the instrument of communication modes.

Along with power carrier instrument in the electrical network, particularly the electric supply meter number increases, power carrier instrument huge amount under platform district, and only depend on the unified allocation of resources of top service end to have significant limitation, in order better to provide service for the user, the on-the-spot maintainer of needs can be in limited scope, solve and measure some problems in real time, like this, both can improve the satisfaction of service, can provide more information for the top service system again.

Background technology

At present, known conventional electric power carrier test mainly is the form appearance with instrument, provide from power line parameters to metering and many functions of test, some function is very complicated, this has also caused this quasi-instrument that following shortcoming is arranged: 1, volume is very big, inconvenience is carried, and only is applicable to the tester of specialty; 2, function is various, but the scene that is not suitable for the maintainer is suitable for custom; 3, do not go out special test and debugging project at application and development, making the test mode complexity needs special staff training.

Traditional power carrier testing tool for above-mentioned reasons, and its distinctive technicality makes that numerous maintainers is difficult to be suitable for, and causes the number of power carrier instrument increasing, and the situation that corresponding service is not in time caught up with.

Simultaneously, in the production run of power carrier instrument, also need be in some common problems of real-time solution, and adopt professional equipment because complicated operation is multiple functional this time, finish one specific, but the phenomenon that often occurs location and being provided with often needs for a long time.

Summary of the invention

From software and hardware, all be not suitable for the shortcoming that the field maintemance personnel are suitable in order to overcome existing power carrier test equipment, the utility model provides a kind of hand held portable field attending device, by this equipment, the maintainer can operate at the scene easily and adopt the instrument of low-voltage power carrier as communication modes, as electric supply meter etc.This hand-held device also can pass through expansion module simultaneously, and the interface of compatible traditional approach is provided, as: infrared reception and RS485 or the like, the scene that maintains easily personnel greatly uses and uses simple mode to tackle various case in the reality.

The technical scheme that its technical matters that solves the utility model adopts is: in hand held industry insulation crust, connected and control low-voltage power carrier communication unit, LCDs and these three parts of user key-press by CPU (central processing unit).The low-voltage power carrier communication unit can be independently, removable module, also can be to adopt and the integrated SOC (system on a chip) of CPU (central processing unit); Device is aided with LCDs and user key-press simultaneously, and the equipment of finishing adopting the low-voltage power carrier communication interface carries out on-the-spot test and function setting.

CPU (central processing unit) is finished the control to entire equipment, for the user provides corresponding equipment to be tested required test event, LCDs shows information needed in a kind of mode intuitively, arranges complete required user key-press simultaneously, finishes the input of live event.

The utility model design has realized flexible configuration to different power carrier agreements and distinct interface with the built-in module form, in actual applications, can join the module of different agreement as required.

The beneficial effects of the utility model are, because it is simple, practical, portable, can pass through simple explanation, the problem that just can allow the on-the-spot electric instrument that solves huge amount of vast maintainer occur also can be convenient to use simultaneously in the production and other possible environment of instrument.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is a realization block diagram of the present utility model.

Embodiment

In the drawings, low-voltage power carrier communication unit (1) is finished power carrier communication, and be connected with CPU (central processing unit) (2), result who handles and process and out of Memory can show intuitively by LCDs (3), user key-press (4) is finished user's input, for the more interface characteristics of compatibility, can increase infrared, expansion interfaces (6) such as RS485, RS232 simultaneously.

Power management (5) part provides the working power of system under the situation of civil power or portable power supply for equipment.

Claims

A kind of hand held that is used for the low-voltage power carrier instrument is safeguarded and testing apparatus, it is characterized in that: it is connected and control low-voltage power carrier communication unit, LCDs and these three parts of user key-press by CPU (central processing unit) in hand held industry insulation crust.
