Description
Technical field
The present invention relates to voltmeter technical field, specially a kind of digital display voltmeter.
Background technology
Voltmeter is the important detection device in power supply system, can carry out whole prison to the curent change in circuit
Control, there is particularly important meaning to improving circuit operation stability and security, find in use, presently used electricity
Pressing table, often function phase to single, is only capable of detecting specific data, but detection data can not be stored, and is worked as
Preceding voltmeter networking capability is also relatively weak, does not on the one hand possess group net operation ability, and another aspect transfer speed of data is slow,
Signal poor anti jamming capability, so as to seriously constrain the raising of power monitoring working automation degree；To some important lines
Precision digital voltmeter, the data of its internal record need to carry out taken at regular intervals or replacement.But traditional digital display voltage
Table is for the degree of protection deficiency of communication interface, electric power cabinet or electric power box the degree of protection deficiency in only outer portion.
The content of the invention
It is an object of the invention to provide a kind of digital display voltmeter, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of digital display voltmeter, including housing, operated key, display, alarm buzzer and control system, wherein display, behaviour
Make key and alarm buzzer and be embedded in housing upper surface, control system is located at enclosure interior, and with operated key, display and alarm
Buzzer is electrically connected；Voltage acquisition module separately sets binding post on protecting crust；Control system includes data processing module, number
According to memory module, I O module, USB port module, communication module, voltage acquisition module, temperature detecting module and timing module,
Separately bottom sets coffret to communication module on protecting crust, and a sliding door, sliding door and shell are set in the outer end of coffret
The chute of body bottom coordinates, and the bottom side wall fixed of sliding door connects the output end of a linear electric machine surely, and the linear electric machine is set
It is connected in housing and with a driving power and a Fingerprint Identification Unit, Fingerprint Identification Unit is also connected with alarm buzzer.
As the further technical scheme of the present invention, data processing module respectively with data memory module, I O module,
USB port module, communication module, voltage acquisition module, temperature detecting module and timing module electrical connection, I O module separately divide
It is not electrically connected with operated key, display and alarm buzzer.
As the further technical scheme of the present invention, housing outer surface is evenly equipped with radiating groove.
As the further technical scheme of the present invention, protective cover is set on the outside of binding post.
Compared with prior art, the present invention has flexible and efficient and stable ability to communicate and networking capability, so as to help
In the automaticity of raising electric circuit inspection work, while separately possess USB abilitys to communicate, detection data can be carried out at any time
Read and instrument operational factor is configured, greatly improve using flexible and convenience, and the present invention is for electricity
Press the protectiveness of data very strong, can effectively prevent malice from stealing.
Brief description of the drawings
Fig. 1 is a kind of structural representation of digital display voltmeter of the present invention.
Fig. 2 is the electrical installation principle schematic of voltmeter main part of the present invention.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1~2, a kind of digital display voltmeter, including housing 4, operated key 2, display 1, alarm buzzer 3 and control
System processed, wherein display 1, operated key 2 and the alarm device of buzzing 4 are embedded in the upper surface of housing 4, and control system is located in housing 4
Portion, and be electrically connected with operated key 2, display 1 and alarm buzzer 3；Control system includes data processing module, data storage
Module, I O module, USB port module, communication module, voltage acquisition module, temperature detecting module and timing module, wherein count
According to processing module respectively with data memory module, I O module, USB port module, communication module, voltage acquisition module, temperature examine
Survey module and timing module electrical connection, I O module be separately electrically connected respectively with operated key 2, display 1 and alarm buzzer 3,
Voltage acquisition module separately sets binding post 7 on protecting crust, and the outside of binding post 7 sets protective cover 6；The outer surface of housing 4 is uniform
There is radiating groove 5.
Separately bottom sets coffret to communication module on protecting crust, and a sliding door 10 is set in the outer end of coffret,
Sliding door 10 and the chute of the bottom of housing 4 coordinate, and the bottom side wall fixed of sliding door connects the output end of a linear electric machine surely, should
Linear electric machine is arranged in housing 4 and is connected with a driving power and a Fingerprint Identification Unit 8, Fingerprint Identification Unit also with buzzing of alarming
Device connects, the controller as linear electric machine in use of Fingerprint Identification Unit 8, when the fingerprint authentication of staff passes through
When, linear electric machine promotes sliding door sidesway to enter in the fixed door 9 of the lower end of housing 4, exposes the coffret of voltmeter, checking is not
By when alarm immediately, improve the Information Security of digital display voltmeter.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Various changes can be made.
