Description
Technical field
The utility model relates to a kind of remote control device more particularly to a kind of radio frequencies without any power supply of energy harvester
Remote control device.
Background technique
While RF remote-controlled technology brings convenient, people have higher requirement to based radio frequency remote controller,
Current based radio frequency remote controller is required to be driven by external power supply or be battery powered, in numerous application scenarios power supply or
The cost that person replaces battery is too high, time-consuming and laborious, demand ten of these occasions to unpowered without battery-driven RF remote
Divide urgent.In view of this, the utility model is a kind of based radio frequency remote controller without any power supply.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is received based on energy
The based radio frequency remote controller without any power supply of storage, has the characteristics that very flexible and convenient.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of based radio frequency remote controller based on energy harvester, comprising: energy harvester, rectifier bridge module, super electricity
Hold, MCU/EEPROM and radio frequency sending set, the energy harvester are connected with rectifier bridge；The rectifier bridge difference
It is connected in super capacitor, MCU/EEPROM, radio frequency sending set；The energy harvester is accompanied with mechanical switch, Ke Yi
It stirs or is produced electricl energy by the moment of lower switch, and (< 5ms) generates metastable voltage output in a short period of time；Institute
The energy harvester stated uses ECO100 collector, can generate the voltage of 5V or so after toggle switch about 2ms
Output.
The rectifier bridge module rectifies the output of energy harvester using diode rectification bridge；It is described
Super capacitor be energy-storage travelling wave tube, energy harvester and the extra power storage of rectification are got up, when electric energy is insufficient in collector
When, electric energy is discharged, whole device is maintained to work normally；The radio frequency sending set has antenna, according to matching for MCU/EEPROM
It sets, the data packet sent will be needed to send in time.
The beneficial effects of the utility model are:
The utility model is produced completely without any power supply in the moment for stirring or pressing energy harvester mechanical switch
Raw electric energy can maintain MCU/EEPROM and radio frequency sending set to work, will contain specific control in time through over commutation and accumulator
The data packet of information processed is sent to receiving end, to realize remote control function；Actual test performance, the utility model can be with
At least power output of 200ms or more is maintained, radio frequency sending set can emit the number for being up to 100ms or more with 10dBm transmission power
According to packet, 300 meters or more of distance can achieve between transmitting-receiving, present apparatus transmitting is highly stable, and the ratio correctly emitted accesses
99.9% or more, it realizes really without power supply, the function of remote wireless control is carried out without battery, it is very convenient and real
With can be applied to other multiple fields.
Detailed description of the invention
For the clearer technical solution illustrated in the embodiment of the present application, will make below to required in embodiment description
Attached drawing makees brief description, it should be apparent that, drawings discussed below is only some embodiments of the present application, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other accompanying drawings.
Fig. 1 is a kind of structural block diagram of the embodiment of the based radio frequency remote controller based on energy harvester of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Revealed the utility model is a kind of based radio frequency remote controller based on energy harvester, as shown in Figure 1, a kind of base
In the based radio frequency remote controller of energy harvester, including energy harvester 100, rectifier bridge module 200, super capacitor 300, MCU/
EEPROM400 and radio frequency sending set 500.
The energy harvester 100 is connected with rectifier bridge module 200, and the rectifier bridge module 200 is respectively at super
Grade capacitor 300, MCU/EEPROM400, radio frequency sending set 500 connect, and energy harvester 100 is accompanied with mechanical switch, Ke Yi
It stirs or is produced electricl energy by the moment of lower switch, and (< 5ms) generates metastable voltage output in a short period of time；
Energy harvester in the application is ECO100 collector, and the voltage that after toggle switch about 2ms, can generate 5V or so is defeated
Out, since the output of energy harvester 100 is unstable, so being rectified.
The utility model rectifies the output of energy harvester using diode rectification bridge 200, to export ratio
More stable 3.3V DC voltage is used to power to MCU/EEPROM 400 and radio frequency sending set 500, wherein super capacitor 300
It is energy-storage travelling wave tube, it is super after the electric energy of collector exhausts for storing the electric energy of energy harvester and rectification output
Capacitor 300 starts to discharge, so as to the normal work of holding circuit.MCU is used to control radio frequency sending set 500, including needs to emit
The power of signal, frequency, packet content etc., and start in time or close radio frequency sending set 500, according to MCU/EEPROM 400
Configuration, the data packet that sends will be needed to send in time.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
