The multi-channel power generation module Connected to the energy storage module, the energy storage module is respectively connected to the power display module and the wireless mouse body. The multi-channel power generation module includes one of the shaking power generation unit 1, the displacement power generation unit 2, the knock power generation unit 3, and the rotation power generation unit 4. More than species.
[0030] The shaking power generating unit is composed of a first powerful magnet and a first power generating coil built into the body of the wireless mouse;
[0031] The displacement generating unit is composed of a second generating coil built into the body of the wireless mouse and a second powerful magnet located under the mouse pad;
[0032] The percussion power generation unit is composed of a piezoelectric ceramic sheet built into the body of the wireless mouse for converting the left and right buttons of the mouse into electric energy;
[0033] The rotating power generation unit is composed of a motor built into the body of the wireless mouse for converting the scrolling of the mouse wheel into electric energy.
[0034] The selection switch is respectively selectively connected with the self-learning home appliance remote control module and the wireless mouse body.
[0035] The energy storage module is composed of a rectifier bridge 5, a Zener diode 6 and a super capacitor 7 connected in sequence.
[0036] The power display module is composed of an STM32 core board 8 and a 12864 display screen 9.
[0037] The self-learning home appliance remote control module is composed of AD009-03140317 chip and peripheral circuits.
[0038] The rectifier bridge is composed of 1N4001 rectifier diodes, and the super capacitor is 0.47F, which has a strong power storage capacity. The energy storage module stores the electric energy generated by the multi-channel power generation module in the super capacitor. The power display module uses the STM32 core board to AD convert the power of the super capacitor and displays it on the 12864. The power display module is a removable module. AD009-03140317 has a highly built-in resonator, triode, high-sensitivity learning circuit, storage circuit, suitable for digital remote control.
[0039] The electric energy generated by the multi-channel power generation module is full-wave rectified by leaving a 1N4001 rectifier diode. After voltage stabilization, it charges a 0.47F super capacitor. The movement of the mouse ensures the continuity of power supply.
[0040] The working principle of the self-learning home appliance remote control module is as follows: (1) Measurement of the transmitted signal waveform: The high-speed main control chip collects the original signal very precisely, and at the same time uses a relatively large capacity RAM as the signal buffer. This step Mainly buffer the original signal in RAM; (2) Analyze the signal: analyze the collected signal, such as the period of signal sending, the commonly used high and low time and other parameters for detailed analysis to facilitate the next step of compression; (3) Compression coding, according to the time of common high and low level, special high and low level time, sending cycle, compress and code the original signal; (4) Store signal: store the compressed and coded data in EEPROM.
[0041] A charging method for a self-charging wireless mouse based on the principle of electromagnetic induction includes the following:
[0042] When using the mouse normally, the mouse moves on the mouse pad, and the kinetic energy of the movement drives the first powerful magnet to cut the first power generating coil to generate electricity. At the same time, the second power generating coil and the second strong magnet generate electromagnetic induction to generate electricity. When the user taps the left and right sides of the mouse Key, the piezoelectric ceramic sheet deforms to generate electricity. When the user rolls the mouse wheel, the wheel drives the gear of the motor to generate electricity;
[0043] The generated electric energy is stored in the capacitor through the rectifier diode and the Zener diode;
[0044] The electric energy of the capacitor supplies power to the power display module and the wireless mouse body or the self-learning home appliance remote control module through the selection switch.
[0045] The four power generation modes work in parallel, and the generated electrical energy is stored in a 0.47F super capacitor after passing through a rectifier bridge and a Zener diode; the electrical energy stored in the super capacitor is supplied to a wireless mouse, a power display circuit and a self-learning home appliance remote control module.
[0046] The specific working process is as follows:
[0047] When the mouse is used normally, the four power generation modes alternately or simultaneously generate power. When the mouse moves horizontally, the power generation unit and the displacement power generation unit will work. When the left and right buttons of the mouse are clicked, the power generation unit will work. When the roller is rolled, the rotating power generation unit works. The electric energy generated by the above four power generation methods passes through the rectifier module, and after all rectification, it is further stabilized and input into the super capacitor for storage. The voltage input pin of the STM32 core board samples the voltage across the supercapacitor in real time and performs A/D conversion internally. The percentage of power is calculated by the formula and displayed on the 12864 LCD screen. The calculation method is as follows: the set maximum voltage V max , Real-time sampling voltage V now , The displayed battery percentage is (V now /V max )*100%. The above description is when the selector switch is turned on the mouse.
[0048] When the selector switch is in the remote control block, the connection between the super capacitor and the wireless mouse body is disconnected, and power is supplied to the self-learning remote control module, and the infrared receiving tube of the self-learning module is aimed at the infrared transmitting tube that is being remote controlled by learning. , Press the learning button and long press the remote control button corresponding to the learned function. After learning, you can use the mouse to control the corresponding home appliances, and you can repeatedly control multiple types of home appliances.
