Description
Technical field
The utility model belongs to electronic device field, and in particular to a kind of billboard of continued power.
Background technology
With the development of society and the progress of science and technology, advertisement turns into the important channel of major businessman publicity.In order in fierceness
Competition in highlight the influence power of brand, almost all of businessman can select billboard to be publicized.Due to billboard quantity
Finite sum businessman it is numerous, the value of leass one of billboard, which rises, to rise again, or even calculates in hours.If the because accident such as power failure
Generation and cause billboard can not be if normal work, this is all great loss for businessman and lease side.Therefore, one
Kind can be when the contingencies such as power failure occur, and the billboard for being still capable of normal work seems extremely important.
The content of the invention
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, and the one kind provided enough exists
When the contingencies such as power failure occur, still it is capable of the billboard of normal work.
What the purpose of utility model was realized in：
A kind of billboard of continued power, it includes billboard main body, and billboard main body is provided with display screen and electrically
Box, the electrical box include built-in power, external application power supply, diode, relay contact, electromagnetic relay, ammeter, protection electricity
Resistance；Ammeter include the first hard contact, ammeter conduction pointer, the second hard contact, diode be connected to built-in power and
Between external application power supply；Built-in power and external application power sources in parallel；Display screen, protective resistance, ammeter be series among circuit and with
Power supply connects；First hard contact and the circuit where ammeter conduction pointer in ammeter, successively with electromagnetic relay, power supply
Positive pole connection.
Two metal contacts are provided with the dial plate of ammeter, the first hard contact is in the position of the zero graduation close to ammeter
On, the second hard contact is arranged near the maximum scale position of ammeter, is also set on the ammeter conduction pointer in ammeter
There is wire.
Above-mentioned display screen is LED electronic displays.
Using said structure, under normal circumstances, billboard is in power supply power supply, has circuit to flow through in external application power circuit,
Ammeter conduction pointer in ammeter deflects to the right, causes contact under ammeter to be separated with ammeter upper contact head, now electromagnetism
Relay circuit disconnects, and electromagnetic relay does not work, thus built-in power circuit disconnects.
External application power supply also charges while providing electric for display screen for built-in power, and built-in power is because diode
Presence, can not be that display screen is powered, thus electricity will not be lost.
When external application power supply is because of forced outage, external application power cut-off, now the ammeter conduction pointer in ammeter is to the left
Deflection, the first hard contact are connected with circuit where ammeter conduction pointer, cause the hard contact of ammeter first and ammeter
Middle ammeter conduction pointer is in contact, and electromagnetic relay work, relay contact contact, connects built-in power circuit, now interior
Power supply is put to power for display screen；
Using two metal contacts are provided with the dial plate of ammeter, the first hard contact is in the zero graduation close to ammeter
On position, the second hard contact is arranged near the maximum scale position of ammeter, on the ammeter conduction pointer of ammeter
Structure provided with wire, the ammeter conductive finger crown can be rested at the first metal contact according to the size of current by ammeter or
At second metal contact.First hard contact is connected with circuit where ammeter conduction pointer with electromagnetic relay, in ammeter
When not having electric current, the ammeter conduction pointer in ammeter deflects to the left, contacts with the first hard contact, has in electromagnetic relay
Electric current passes through, and electromagnetic relay is started working；
Structure of the display screen for LED electronic displays is used, can so be dropped significantly on the basis of good advertisement broadcasting
Energy consumption required for low display screen.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the utility model external structure schematic diagram；
Fig. 2 is the utility model internal structure schematic diagram；
Fig. 3 is current meter structure schematic diagram in Fig. 2.
Embodiment
A kind of billboard of continued power shown in Fig. 1 and Fig. 2, it includes billboard main body 1, and billboard main body 1 is provided with
Display screen 2 and electrical box 3, electrical box 3 include built-in power 4, external application power supply 5, diode 6, relay contact 7, electromagnetism after
Electrical equipment 8, ammeter 9, protective resistance 10；Ammeter 9 includes the first metal dots 11, ammeter conduction pointer 12, the second metal and touched
Point 13, diode 6 is connected between built-in power 4 and external application power supply 5；Built-in power 4 is in parallel with external application power supply 5；Display screen 2,
Protective resistance 10, ammeter 9 are series among circuit and connected with power supply；First hard contact 11 and ammeter in ammeter 9
Circuit where conductive pointer 12, successively the positive pole with electromagnetic relay 8, power supply 4 be connected.
As shown in figure 3, being provided with two metal contacts in the dial plate of ammeter 9, the first hard contact is close to ammeter 9
On the position of zero graduation, the second hard contact is arranged near the maximum scale position of ammeter 9, and the ammeter of ammeter 9 is led
