Description
Technical field
It the utility model is related to technical field of battery management, more particularly to a kind of simple and practical battery electric quantity display system
System.
Background technology
Old style equipment does not have battery electric quantity to show, the equipment for typically having electricity to show all can be integrated design, if
Damage can not repair or be not easy to repair, and can influence equipment work.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of simple and practical battery electric quantity display system, to solve
Deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions：
A kind of simple and practical battery electric quantity display system is provided, including power supply, single-chip microcomputer, signal amplifier, electricity show
Display screen, civil power measure loop and voltage detection circuit, the power supply, the single-chip microcomputer, the signal amplifier and the electricity
Display screen is sequentially connected, and the power supply connects the signal amplifier and the electricity display screen, the single-chip microcomputer difference respectively
The civil power measure loop and the voltage detection circuit are connected, the civil power measure loop includes the first bleeder circuit and light
Coupling, the voltage detection circuit include the second bleeder circuit.
Above-mentioned simple and practical battery electric quantity display system, wherein, the electricity display screen can be replaced indicator lamp.
Compared with the prior art, the beneficial effects of the utility model are：
System is independent, and compact is applied widely, and detection is accurate, and wiring is simple, and installation site is convenient, flexible.
Brief description of the drawings
Form a part of accompanying drawing of the present utility model to be used for providing further understanding to of the present utility model, this practicality is new
The schematic description and description of type is used to explain the utility model, does not form to improper restriction of the present utility model.
In accompanying drawing：
Fig. 1 shows the structural representation of the simple and practical battery electric quantity display system of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
With reference to shown in figure 1, the simple and practical battery electric quantity display system of the utility model includes power supply 1, single-chip microcomputer 2, letter
Number amplifier 3, electricity display screen 4, civil power measure loop 5 and voltage detection circuit 6, power supply 1, single-chip microcomputer 2, signal amplifier 3
It is sequentially connected with electricity display screen 4, power supply 1 connects signal amplifier 3 and electricity display screen 4 respectively, and single-chip microcomputer 2 connects city respectively
Electro-detection loop 5 and voltage detection circuit 6, civil power measure loop 5 include the first bleeder circuit 51 and optocoupler 52, and voltage detecting is returned
Road 6 includes the second bleeder circuit 61.In the technical program, electricity display screen 4 can be replaced indicator lamp.
First, judge whether to charge by the detecting system of civil power measure loop 5, battery voltage detection system by using
The mode of electric resistance partial pressure, monitors cell voltage in real time, and single-chip microcomputer 2 reads corresponding magnitude of voltage by A/D mouths, then by battery electric quantity
It is shown on screen.Because electricity is shown by single-chip microcomputer 2 to send signal, it is possible to customized corresponding aobvious according to specific requirement
Display screen and pattern, can be screen or indicator lamp, can be convenient, flexible with customized, and function is simple and practical, compact.
Illustrate：Electricity display screen 4 is divided into 5 lattice, and 20% electricity is represented per lattice (because normal device can all have low-voltage variation, institute
It is exactly electricity when battery is filled to equipment low-voltage variation with total electricity), when equipment works, often decline 20%, the finger on screen
Show that lamp extinguishes a lattice, until so indicator lamp extinguishes, equipment automatic protection can also be by monitoring electricity come control device.Fill
When electric, time detecting module has detected civil power, and screen display will show charge mode, by the display mode of revolving horse lantern, often
Charging 20%, lights a lattice, and the continuation of other indicator lamps is glittering according to revolving horse lantern form, until battery is full of.
From above-described embodiment as can be seen that advantage of the present utility model is：
System is independent, and compact is applied widely, and detection is accurate, and wiring is simple, and installation site is convenient, flexible.
Specific embodiment of the utility model is described in detail above, but the utility model is not restricted to the above
The specific embodiment of description, it is intended only as example.To those skilled in the art, any equivalent modifications and substitute also all
Among category of the present utility model.Therefore, the impartial conversion made in the case where not departing from spirit and scope of the present utility model
And modification, it should all cover in the scope of the utility model.
