Description
Technical field
The present invention relates to a kind of wireless receiver, especially a kind of portable mobile wireless decoding receiver.
Background technology
At present, the application of wireless technology has more and more widely promoted wireless encoding chip and the use of decoding chip in applications of wireless technology low-cost, low-power consumption.In numerous applications, all be to utilize the 220V AC power, the wireless receiving decoding chip that is transformed to by power supply provides operate as normal required DC power supply, therefore, has limited the application of decoding chip on portable product to a certain extent.
The utility model content
The objective of the invention is at the deficiency of existing decoding chip on using, a kind of portable mobile wireless decoding receiver based on decoding chip is provided,, improve portable by lithium battery power supply.
According to technical scheme provided by the invention, described portable mobile wireless decoding receiver comprises: 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, described decoding chip module and wireless receiving module receive the code signal of given frequency range and realize decoding; Described 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 by boost module, and described decoding chip module links to each other with wireless receiving module.
One of described lithium cell charging protection module comprises sound, the light reminding module of charging, or both.
One of described lithium battery discharge prevention module comprises sound, the light reminding module of discharge, or both.
One of described low-voltage reminding module comprises sound, the light reminding module of low-voltage, or both.The low-voltage reminding module detects the lithium battery output end voltage in real time, when voltage is lower than set point, reports to the police by low-voltage warning light, voice prompt.
Advantage of the present invention is: can provide its steady operation required DC power supply for decoding chip and wireless receiving circuit by common lithium battery; lithium battery charge and discharge protection module realizes the charge and discharge monitoring of lithium battery science; prolong the useful life of lithium battery; improve the safety that lithium battery uses; by low-voltage prompting prompting user is lithium cell charging in time, also can not influence the operate as normal of receiving circuit in charging process.
Description of drawings
Fig. 1 is a system architecture diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention includes: 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, described decoding chip and wireless receiving module receive the code signal of given frequency range and realize decoding; Described 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 by boost module, and described decoding chip links to each other with wireless receiving module.
Specific embodiment is as follows:
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 is too much, will directly influence the ionization activity of lithium battery interior lithium ion, cause the damage of lithium battery.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
Described 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.
Described 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 present invention can provide the DC power supply of required steady operation for decoding chip by common lithium battery, and simple in structure, cost is low, easily implements, and is applicable to the decoding receiver of various portable mobile wireless products.
