Description of drawings
Fig. 1 is the system architecture diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The utility model comprises: 3.7V lithium battery, lithium cell charging protection module, lithium battery discharge prevention module, low-voltage reminding module, boost module, decoding chip module and wireless receiving module, said decoding chip module and wireless receiving module receive the code signal of given frequency range and realize decoding; Said lithium battery connects lithium cell charging protection module, lithium battery discharge prevention module and low-voltage reminding module respectively, and connects decoding chip module and wireless receiving module through boost module, and said decoding chip module links to each other with wireless receiving module.
Specific embodiment is following:
1. charge protection module
Lithium battery is in charging process, if improper use will produce a large amount of bubbles, reduces the useful life of lithium battery, has buried potential safety hazard simultaneously.Therefore, when using the 3.7V lithium battery, it has been designed charge protector, the 3.7V lithium battery is when charging, and charge protector can prevent that the over-charge of lithium battery electricity from causing danger.
2. discharge prevention module
If the lithium battery discharge too much,, cause the damage of lithium battery with the ionization activity that directly influences the lithium battery interior lithium ion.Therefore, design lithium battery discharge prevention module, when voltage was lower than certain value, discharge protection circuit turn-offed the output of lithium battery, and discharge protection circuit can prevent that the lithium battery over-discharge can from influencing useful life;
2. low-voltage reminding module
Lithium battery when voltage is lower than certain value in discharge the voltage exponentially descend, the low-voltage reminding module is realized when lithium battery forces down in certain value, luminous warning is pointed out lithium battery is charged.
3. wireless receiving module
Said wireless receiving module is realized the reception of wireless signal and the amplification of signal, and amplifying signal is input to the data pin of decoding chip.
4. boost module
Boost module with the voltage rise of 3.7V lithium battery to 5V, for decoding chip and wireless receiving module provide stable operating voltage.
Said lithium cell charging and discharge prevention module, low-voltage reminding module, boost module, wireless receiving module all can be made up of integrated chip and peripheral circuit thereof, also can adopt the discrete component mode to realize.
The utility model can be the DC power supply that decoding chip provides required steady operation through common lithium battery, and simple in structure, cost is low, is prone to implement, and is applicable to the decoding receiver of various portable mobile wireless products.
