The self-powered rotation sensing device provided by the present embodiment will be described in detail with reference to the drawings. The self-powered rotation sensing device described in this embodiment is applied to a light console. Referring to fig. 1, a schematic structural diagram of a self-powered rotation sensor device is shown. As shown in fig. 1, the self-powered rotation sensing device 1 includes a mechanical rotation sensing module 11, a power generation module 12, a rectification module 13, an energy storage module 14, and a wireless communication module 15.
The mechanical rotation sensing module 11 is used for sensing signals of mechanical power and rotation when entering a mechanical rotation state. Referring to fig. 2A and 2B, a front view and a bottom view of a mechanical rotation sensor module are shown. As shown in fig. 2A and 2B, the mechanical rotation sensing module 11 includes: the roller 111 is sleeved on a rotary encoder 112 on the roller 11 and is sleeved on a speed increasing gear set on the rotary encoder 112. When the roller 111 enters a mechanical rotation state, the roller 111 drives the speed increasing gear set to rotate in an acceleration mode, and mechanical power is generated.
In the present embodiment, the rotary encoder 112 is an incremental rotary encoder. The incremental rotary encoder converts the time sequence and phase relation of an angle code disc through two photosensitive receiving tubes to obtain the increase (positive direction) or decrease (negative direction) of the angle displacement of the angle code disc.
With continued reference to fig. 2A and 2B, the rotary encoder 112 is disposed on the roller 111 through a rotary encoder roller 113, and mechanically rotates the mechanical power and the rotation sensing signal through the roller 111 sleeved on the rotary encoder roller 113.
The speed increasing gear set comprises a multi-stage speed increasing gear set.
In the present embodiment, the multistage speed increasing gear set includes a first stage driving gear 114, a second stage driven main gear 115, a second stage driven sub-gear 116 coaxial with the second stage driven main gear 115, a third stage driven main gear 117, a third stage driven sub-gear 118 coaxial with the third stage driven main gear 117, and a fourth stage brushless motor shaft gear 119.

When the roller 111 mechanically rotates mechanical power and rotation sensing signals, the first-stage driving gear 114 is driven to rotate at the same speed, then the second-stage driven main gear 115 is driven to engage and accelerate, the second-stage driven main gear 115 and the second-stage driven secondary gear 116 are coaxial, the rotating speed is accelerated and then transmitted to the third-stage driven driving gear 117 to engage and accelerate, the third-stage driven driving gear 117 and the third-stage driven secondary gear 118 are coaxial, and the rotating speed is accelerated and then transmitted to the fourth-stage brushless motor shaft gear 119, so that the fourth-stage rotating speed is accelerated.
The power generation module 12 is configured to receive the mechanical power and convert the mechanical power into electrical energy.
Specifically, the power generation module 12 includes a brushless motor 12 sleeved on the fourth-stage brushless motor shaft gear. Through the acceleration of four-stage speed-increasing gear set, the stator coil of the internal cutting of the brushless motor generates induced electromotive force, namely alternating current.
The rectifying module 13 connected to the power generating module 12 is used for rectifying the alternating current generated by the power generating module 12 into direct current. As shown in fig. 3, the rectifier module 13 is formed by a diode bridge connection.
The energy storage module 14 connected to the rectifier module 13 is used for storing the converted direct current. With continued reference to fig. 3, the energy storage module 14 includes a schottky diode, a current limiting resistor, a farad capacitor, a discharge diode, and a load; the Schottky diode comprises a Schottky diode, a current-limiting resistor, a load and a current-limiting resistor, wherein the Schottky diode is connected with a positive pole end rectifying module, a negative pole end of the Schottky diode is connected with one end of the current-limiting resistor, the other end of the current-limiting resistor is connected with one end of the Faraday capacitor, the other end of the Faraday capacitor is connected with one end of the load, and the other end of the load is connected with one end of the current-limiting resistor; the current limiting resistor is connected in parallel with the discharge diode. The positive electrode of the rectifier module 13 is connected in series with the Schottky diode for reverse current protection, and meanwhile, the voltage limiting test can be carried out, so that the voltage is limited within the rated voltage of the Farad capacitor. Because the internal resistance of the farad capacitor is small, if the front end is not subjected to charging current limiting control during charging, larger impact current is easily caused, and the farad capacitor is damaged. Therefore, the farad capacitor needs to be protected from being damaged through measures such as charging voltage stabilization and current limiting.
In practical application, the energy storage E of the farad capacitor is 1/2U 2C, the leakage current of the farad capacitor is about microampere, the power consumption of the circuit part is about 1-5 mA Vcc under the condition of 100HZ transmission data packet, the electric quantity of the equipment can be calculated and stored for several months, and the electric quantity generated in use is abundant.
And the wireless communication module 15 connected with the energy storage module 14 is used for receiving the power supply of the energy storage module and transmitting the rotation sensing signal parameters generated by the mechanical rotation sensing module. The wireless communication module can adopt a Bluetooth transmission module. The Bluetooth transmission module is composed of an ultra-low power consumption Bluetooth 2.4G transceiver, a crystal oscillator and a radio frequency circuit.
Specifically, after the energy storage module 14 supplies power to the bluetooth transmission module 15, the roller drives the rotary encoder shaft to rotate, three groups of square wave pulses A, B and Z phase data are directly collected and output by using the photoelectric conversion principle, and then the rotation sensing signal parameters generated by the mechanical rotation sensing module are transmitted by the radio frequency antenna through the bluetooth transmission module 15.
In summary, the self-powered rotation sensor device provided by the invention utilizes mechanical power generated by mechanical rotation of the roller transmission sensor to drive the generator to generate electric energy, and obtains a stable working power supply through steps of energy storage, voltage stabilization and the like. Meanwhile, a self-generating mechanism can generate a damping effect on the rotation of the rotation sensor, so that the rotation of the roller of the rotation sensor is more stable, the damping effect is a defect for other application scenes, and the damping effect is beneficial to the application of the light console.
The invention effectively overcomes various defects in the prior art and has high industrial utilization value.
