The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The embodiment of the invention provides a transmitter and a control system; as shown in fig. 1, the present disclosure provides a control system, which includes the transmitter 100, and a target network 200; the target network 200 may be any one or a combination of a Zigbee network, a WIFI network, and a bluetooth network. Wherein the target network 200 may be formed based on a gateway 202; the gateway 202 may be any device or combination of devices capable of forming and/or managing the corresponding target network 200, and the number of the gateways 202 may be one or multiple, but is not limited thereto. In a specific example, the gateway 202 is a gateway device or a sound box with a gateway function.
The target network 200 is provided with at least one of the following target devices 201: intelligent wall opening, intelligent curtain, intelligent lamp, intelligent audio amplifier. The target device 201 may be controlled by the signal sent by the transmitter 100 to perform a corresponding action.
The control system further comprises a mobile terminal 300 connected to the target network 200, which may be configured to be able to communicate with the transmitter 100, devices in the target network 200 and/or gateways, wherein the communication may be direct or indirect. The mobile terminal 300 may be, for example, a mobile phone, a tablet computer, a computer, etc. In addition, the mobile terminal 300 may also acquire the signal sent by the transmitter, so as to control or implement the forwarding of the signal, or implement the control based on the signal.
The target device 201 is further configured to: receiving a signal transmitted by the transmitter 100 through the target network 202, and sending a control message corresponding to the signal to a server 400; the mobile terminal 300 is further configured to: the control packet is obtained from the server 400. In an example, the distribution network process of the transmitter 100 may be implemented by relying on a mobile terminal 300, and the mobile terminal 300 is further configured to send security information (e.g., a network access password) of the target network 200 to the transmitter 100 when executing the distribution network. In an example, the network distribution process of the gateway 202 may be implemented by relying on the mobile terminal 300, and the mobile terminal 300 is further configured to send the security information (e.g., a network access password) to the gateway 202, so that the gateway 202 joins the target network 200.
Referring to fig. 2a, a structural diagram of a transmitter 100 according to an embodiment of the present invention is shown; the transmitter 100 comprises: a self-generating motor 101 for generating electric power; an energy storage assembly 102 electrically connected to the self-generating motor 101 to store the electric energy; a signal transmitting component 103 for transmitting a signal; a first energy transfer component 104 disposed between the energy storage component 102 and the signal transmitting component 103 and adapted to not supply power to the signal transmitting component 103 when the output voltage of the energy storage component 102 is in a specified voltage interval; and: when the output voltage of the energy storage component 102 is in a non-specified voltage interval, the signal transmitting component 103 is powered to form a power supply stage, so that the signal transmitting component 103 is powered on and transmits a signal.
In the non-specified voltage interval, it can be understood that: not in the specified voltage interval. The designated voltage interval can be understood as any voltage interval designated in advance or during working. The specified voltage interval may be characterized by an upper operating voltage limit and/or a lower operating voltage limit. In an example, the designated voltage interval may refer to a voltage interval ending at the lowest operating voltage of the signal transmitting assembly 103, and further, the non-designated voltage interval may be understood to include a voltage interval starting at the lowest operating voltage and ending at the highest operating voltage of the first energy transfer assembly. Illustratively, if the operating voltage interval of the signal emitting component 103 is 1.8V-3.3V, and the highest input voltage of the first energy transfer component 104 is 6V, the specified voltage interval is [0V,1.8V ], and the non-specified voltage interval is (1.8V,6V ], where the specified voltage interval may be understood as a charging process of the energy storage component 102 before the signal emitting component 103 is powered on, and/or a stopping process after the power consumption in the energy storage component 102 is lower than the lowest operating voltage of the signal emitting component 103 after the signal emitting component is powered on to start operating.
In this embodiment, by setting the first energy transfer component 104 and setting the first energy transfer component 104 not to supply power to the signal transmitting component 103 when the output voltage of the energy storage component 102 is in a specified voltage interval, so that the supply voltage of the signal transmitting component 103 is within the operating voltage range thereof, the situation that the power is wasted due to the reduction or failure of the signal transmitting efficiency caused by the insufficient supply voltage is avoided, and in addition, by setting different power supply states of the specified voltage interval and the non-specified voltage interval, the power supply loop of the signal transmitting component 103 can be disconnected when the output voltage of the energy storage component 102 is not enough to support the signal transmitting component 103 to continue operating, and it can be ensured that the supply voltage of the signal transmitting component 103 during operating is sufficient (i.e. at least greater than the lowest operating voltage thereof), thereby improving the stability of signal transmission.
The self-generating motor 101 can be understood as a self-generating motor for electromagnetic power generation, a self-generating motor for piezoelectric ceramic power generation or other self-generating motors with self-generating function; taking a self-generating motor for electromagnetic power generation as an example, the following explanatory description is made on the technical problems to be solved and the technical effects to be achieved by the embodiments of the present disclosure: assuming that the electric energy generated by the self-generating motor 101 during one operation is a relative fixed value of 200uj, the electric energy W generated by the self-generating motor 101 during each operation (including a forward pressing operation or a reverse resetting operation) is a fixed value of 200uj, and there are:
Figure BDA0003547007190000051
in the above formula, W is 200uj, C is the capacitance of the energy storage device 102, and U is the output voltage of the energy storage device 102; it should be noted that for ease of expression and understanding, the above formula ignores non-dominant voltage drops due to other factors in the circuit, such as diode drops, triode drops, etc. Based on the above formula, the square of the output voltage of the energy storage device 102 is inversely proportional to the capacitance of the energy storage device 102. Further, assuming that the capacitance value of the energy storage device 102 is 15uF, the maximum output voltage of the energy storage device 102 can be calculated to be 5.2V based on the above formula. The operating voltage range of the signal transmitting component 103 is generally 1.8V to 3.3V, so thatThe output voltage of the energy storage component 102 needs to be converted into 1.8V to 3.3V to supply power to a back-end circuit (for example, a processing unit MCU, a signal transmitting unit RF SOC, and other circuits forming the signal transmitting component 103). Similarly, based on the above formula, if the capacitance of the energy storage component 102 is gradually increased on the basis of 15uF, the output voltage generated on the energy storage component 102 during each operation of the self-generating motor 101 will gradually decrease, and when the capacitance of the energy storage component 102 is within a certain range, the output voltage of the energy storage component 102 will decrease to 1.8V to 3.6V, so as to directly supply power to a back-end circuit (such as the signal emitting component 103 in this embodiment); for example, if the capacitance value of the energy storage assembly 102 is 33uF, under the condition that the generated electric quantity of the self-generating motor 101 is still 200uj, the output voltage of the electric energy generated by one time of the action of the self-generating motor 101 on the energy storage assembly 102 is reduced to 3.5V, and at this time, the output voltage of the energy storage assembly 102 may be directly supplied to the signal transmitting assembly 103 at the rear end. However, if the power supply voltage of the signal transmitting element 103 is lower than the minimum operating voltage (e.g. 1.8V), the signal transmitting element 103 will stop operating, and therefore, when the output voltage of the energy storage element 102 is lower than 1.8V, the residual power in the energy storage element 102 cannot be continuously supplied to the back-end circuit, which results in the waste of the residual power, according to the above formula: residual electric quantity W1As the capacitance value C of the energy storage component 102 takes 33uF, the residual electric quantity is 54uj, and it can be seen that the larger the capacitance value of the energy storage component 102 is, the more the residual electric quantity is, the less the electric quantity actually used for the rear-end signal transmitting component 103 to operate is, and thus the utilization rate of the electric energy of the self-generating motor 101 is low.
To solve the problem of power supply and utilization rate of energy collection of the self-generating motor 101, in some embodiments of the present disclosure, the first energy transfer assembly 104 includes at least one linear adjustment unit 1041; the input end of the linear adjustment unit 1041 is electrically connected to the energy storage element 102, and the output end is electrically connected to the signal transmitting element 103, so as to linearly adjust the output voltage of the energy storage element 102 to the power supply voltage suitable for the signal transmitting element 103, and supply power to the signal transmitting element, thereby forming the power supply stage. In this embodiment, the linear adjustment unit 1041 adjusts the voltage of the electric energy generated by the self-generating motor 101 and then supplies power to the back-end circuit, so that the output power supply voltage can also meet the power supply requirement of the back-end circuit when the capacitance value of the energy storage assembly 102 is small, the residual electric quantity of the self-generating motor 101 can be reduced, the overall power supply efficiency and the utilization rate of the electric energy generated by the self-generating motor 101 are improved, and the output voltage of the energy storage assembly 102 can be converted into the voltage required by the operation of the signal transmitting assembly 103.
In some embodiments, referring to fig. 2b, the first energy transfer element 104 comprises a transistor; the transistor works in a linear region, the transistor is arranged between the energy storage component 102 and the signal transmitting component 103, the control end of the transistor is directly or indirectly controlled by the voltage fed back by the input end of the signal transmitting component 103, the internal resistance of the transistor is adjusted based on the fed back voltage, so that the output voltage of the energy storage component 102 is linearly adjusted to the supply voltage suitable for the signal transmitting component 103, and the signal transmitting component 103 is powered, and the power supply stage is formed.
Further, as can be seen from fig. 2b, the first energy transfer component 104 further includes a configuration circuit for matching the transistor, specifically including a voltage regulator, an error amplifier, a first impedance element and a second impedance element; a first end (for example, an S pole of a PMOS transistor) of the transistor is connected to the energy storage component 102, and a second end (for example, a D pole of a PMOS transistor) of the transistor is connected to the signal emitting component 103; one end of the voltage stabilizing element is connected to the energy storage assembly 102, and the other end of the voltage stabilizing element is connected to the reverse input end of the error amplifying element, and is used for providing a specified reference voltage for the direction input end of the error amplifying element; the first impedance element and the second impedance element are connected in series and then connected to the second end of the transistor, and are used for dividing the voltage fed back by the second end; the positive input end of the error amplification element is connected between the first impedance element and the second impedance element, and the output end of the error amplification element is connected to the control end of the transistor (for example, the G pole of a PMOS (P-channel metal oxide semiconductor) transistor); the output voltage of the energy storage component 102 is adjusted to be suitable for the voltage of the signal transmitting component 103. The transistor can be implemented as any one or combination of a PMOS tube, an NMOS tube or a triode. Illustratively, as shown in fig. 2b, the first impedance element is set as a resistor R1, the second impedance element is set as a resistor R2, the voltage stabilizing element is set as a zener diode Q2, the error amplifying element is set as an error amplifier E1, the transistor is set as a PMOS transistor Q1, and the PMOS transistor Q1 is set to operate in a linear region; one end of the resistor R2 is grounded, the other end of the resistor R2 is electrically connected to the positive input end of the error amplifier E1 and one end of the resistor R1, and the other end of the resistor R1 is electrically connected to the D-pole of the PMOS transistor Q1; the inverting input end of the error amplifier E1 is connected with a stable reference voltage, one end of the Zener diode Q2 provides the reference voltage for the error amplifier E1, the other end of the Zener diode Q2 is respectively connected to the S pole of the PMOS tube Q1 and the energy storage component 102, and the output end of the error amplifier is connected to the G pole of the PMOS tube Q1 through a driving circuit;
when the self-generating motor 101 operates to generate electric energy, the energy storage component 102 stores the electric energy and supplies power to the first energy transfer component 104 through the S pole of the PMOS transistor Q1, the zener diode Q2 provides a stable reference voltage for the reverse input end of the error amplifier E1, and the resistor R1 and the resistor R2 divide the output voltage of the first energy transfer component 104 and then feed the divided voltage back to the forward input end of the error amplifier E1; the resistor R1, the resistor R2, the reference voltage and the error amplifier E1 form a voltage negative feedback circuit, and the PMOS transistor Q1 operates in a linear region, so that the internal resistance of the PMOS transistor Q1 can be adjusted based on the output of the error amplifier E1, thereby achieving the purpose of controlling the output voltage of the first energy transfer component 104; for example, the following steps are carried out: assuming that the output voltage of the first energy transfer assembly 104 is set to 3V, the reference voltage may be set to 1.5V, and the resistance value of the resistor R1 is set to be equal to the resistance value of the resistor R2, when the output voltage of the first energy transfer assembly 104 is lower than 3V, the voltage of the positive input terminal of the error amplifier E1 is lower than 1.5V, the error amplifier E1 outputs a negative value, at this time, the PMOS transistor Q1 is turned on, the internal resistance becomes smaller, the voltage drop across the PMOS transistor Q1 in the main circuit power loop of the first energy transfer assembly 104 decreases, and the power supply voltage obtained by the signal transmitting assembly 103 becomes larger; when the output voltage of the first energy transfer component 104 is greater than 3V, and the voltage of the forward input terminal of the error amplifier E1 is higher than 1.5V, the error amplifier E1 outputs a positive value, at this time, the PMOS transistor Q1 is turned on, and the internal resistance becomes large, the voltage drop across the PMOS transistor Q1 in the circuit main power loop of the first energy transfer component 104 increases, and the supply voltage obtained by the signal transmitting component 103 becomes small, so that the voltage reduction and stabilization function of the supply voltage of the signal transmitting component 103 by the first energy transfer component 104 is realized.
Preferably, in some embodiments, as shown in fig. 2b, the first energy transfer assembly 104 further includes an output capacitor disposed at the output end of the first energy transfer assembly 104 for filtering the output voltage of the first energy transfer assembly 104. Specifically, referring to fig. 2b, the output capacitor is configured as a capacitor C2, one end of the capacitor C2 is grounded, and the other end is connected to the D-pole of the PMOS transistor Q1 and the signal emitting element 103 respectively. In operation, the voltage U2 across the capacitor C2 and the current I flowing from the capacitor C2 are monitored2As shown in fig. 2C, U1 is the output voltage curve of the capacitor C1, and U2 is the output voltage curve of the capacitor C2.
As can be seen from fig. 2C, after the self-generating motor 101 powers the signal transmitting assembly 103 to power on the signal transmitting assembly 103, the current I of the capacitor C22Increases when the current I flows from the capacitor C2 in fig. 2b2Increasing, after the signal transmission is finished, the current I2Tending to 0. During the signal transmission process, the load (signal transmission component 103) is electrifiedThe current is increased, the capacitance value of C2 is not changed, the filtering effect of the capacitor C2 is deteriorated, so the voltage ripple at both ends of the capacitor C2 is increased during signal transmission, after the signal transmission is finished, the signal transmission assembly 103 enters the sleep mode, the load current in the circuit is reduced, and the ripple voltage is reduced. Therefore, the voltage ripple is related to the capacitance of the filter capacitor (C2) and the load current. When the capacitance value of the filter capacitor is fixed, the larger the load current is, the larger the ripple voltage is; when the load current is constant, the larger the filter capacitor is, the smaller the ripple voltage is. Therefore, it is preferable that the capacitance of the output capacitor is set to be greater than or equal to 1uF to reduce the Weak wave voltage; in a specific embodiment, the capacitance value of the output capacitor is set to 4.7 uF.
In some embodiments, the linear regulating unit 1041 includes a low dropout regulator, an input terminal of which is electrically connected to the energy storage component 102, and an output terminal of which is electrically connected to the signal transmitting component 103; and during operation, the minimum voltage difference of the low-dropout regulator is less than or equal to 0.2V (in fig. 2c, although the minimum voltage difference also exists, it is not specifically shown because it is smaller), so as to facilitate energy transfer, and the electric energy stored in the energy storage assembly 102 can be used for supplying energy to the signal transmitting assembly 103 at the rear end as much as possible. As shown in fig. 2d, during the output voltage drop, there is a minimum voltage difference, which is the voltage difference value obtained by subtracting U2a (the output voltage value of the low dropout linear regulator) from U1a (the input voltage value of the low dropout linear regulator). The concrete explanation is as follows: when the voltage of the energy storage assembly 102 plus the voltage difference of the low dropout regulator is smaller than the lowest working voltage of the signal transmitting assembly 103, the signal transmitting assembly 103 stops working, and the electric energy in the energy storage assembly 102 becomes residual electric quantity to be wasted, so that the smaller the voltage difference of the low dropout regulator is, the more the electric energy in the energy storage assembly 102 can be transmitted to the signal transmitting assembly 103 under the condition that the electric energy stored in the energy storage assembly 102 is fixed; for example, the following steps are carried out: if the voltage of the energy storage assembly 102 is 5V and the lowest working voltage of the signal transmitting assembly 103 is 1.8V, when the voltage difference of the low-dropout linear regulator is 0.5V and the voltage of the energy storage assembly 102 drops to 2.3V, the signal transmitting assembly 103 cannot be powered continuously; when the voltage difference of the low-dropout linear regulator is 0.4V and the voltage of the energy storage assembly 102 is reduced to 2.2V, the signal transmitting assembly 103 cannot be powered continuously; if the voltage difference of the low dropout regulator is 0.2V, and the voltage of the energy storage assembly 102 is reduced to be less than 2V, the signal transmitting assembly 103 cannot be powered continuously; it can be seen that as the voltage difference of the low dropout regulator decreases, the voltage at which the energy storage assembly 102 stops supplying energy also decreases gradually, and according to the energy formula, the lower the voltage, the smaller the residual capacity. The application combines the whole scheme of transmitter, will low-dropout linear regulator's pressure differential sets up to be less than or equal to 0.2V for the electric energy that stores in energy storage component 102 can be used for as much as possible for the rear end signal transmission component 103 energy supply.
In one embodiment, if the first energy transfer element 104 comprises the ldo linear regulator, the transmitter 100 at least comprises the following operating states:
the first working state: when the output voltage of the low dropout regulator is greater than the working voltage of the signal transmitting assembly 104 (for example, the lowest working voltage of the processing unit), the signal transmitting assembly 103 transmits a signal in both the output voltage stabilization phase and the output voltage reduction phase of the low dropout regulator; or, the second operating state: when the output voltage of the low dropout regulator is equal to the working voltage of the signal transmitting assembly 103, the signal transmitting assembly 103 transmits a signal at the output voltage stabilization stage of the low dropout regulator, and does not transmit a signal at the output voltage reduction stage of the low dropout regulator, so that in a signal transmitting process, the electric energy generated by the self-generating motor 101 which is controlled to act once or for a limited time can support the signal transmitting assembly 103 to complete the transmission of all data packets in the signal transmitting process.
In the present embodiment, the signal transmitting assembly 103 can have stable signal transmitting time and signal transmitting effect by setting the first operating state and the second operating state of the first energy transfer assembly 104. The specific description is as follows: the output voltage of the low dropout regulator is generally 1.8V-5V, and the output voltage of the low dropout regulator needs to be matched with the withstand voltage value of the signal transmitting assembly 103; preferably, the output voltage of the low dropout linear regulator is selected to be 1.8V or 3.3V; therefore, when the signal transmission module 103 has inconsistent signal transmission effect parameters (packet transmission speed, packet loss rate, etc.) in the working voltage interval of 1.8V to 3.3V (for example, the signal transmission module 103 has better transmission effect in the high voltage interval of 3.3V, and the transmission effect gradually deteriorates with the decrease of the supply voltage), the low dropout linear regulator with a voltage output of 3.3V is selected, so that the signal transmission module 103 can transmit at least part of the signals with better transmission effect in the high voltage supply interval, and after the signal transmission module 103 has transmitted part of the data (for example, the 1 st packet data packet in fig. 2 d) based on the stable 3.3V supply voltage (the stable stage) output by the output capacitor, the voltage of the output capacitor gradually decreases from 3.3V due to the voltage decrease of the first energy storage element 1021 (energy storage capacitor) in the energy storage module 102, then, the process of gradually decreasing the output voltage of the output capacitor along with the transmission of the signal (the decreasing stage) is performed, and although the output voltage decreases, because the output voltage is still greater than the minimum working voltage (e.g., 1.8V) of the signal transmitting assembly 103, the signal transmitting assembly 103 can still continue to operate until the power supply voltage is less than the minimum working voltage of the signal transmitting assembly 103, and then stops operating, in other words, when the transmitting effect of the signal transmitting assembly 103 in a high voltage interval (e.g., a voltage interval where 3.3V is located) is better than that in a low voltage interval (e.g., a voltage interval where 1.8V is located), the output voltage of the low dropout linear regulator is set to 3.3V, and further, the beneficial effects that can be achieved are that: when the electric energy of the first energy storage element is sufficient and the output voltage of the low dropout regulator can be stabilized at 3.3V, the signal transmitting assembly 103 can complete transmission of a part of data packets in a signal transmission process based on the power supply voltage of 3.3V with a better transmission effect, and when the electric energy of the first energy storage element decreases and the output voltage of the low dropout regulator cannot be stabilized at 3.3V and gradually decreases, the signal transmitting assembly 103 can still continue to complete transmission of the remaining data packets in the signal transmission process before the output voltage of the low dropout regulator decreases to the lowest working voltage of the signal transmitting assembly 103; furthermore, based on the power supply voltage provided by the low dropout regulator, the signal transmitting component 103 can utilize the signal transmitting effect of the high voltage section, and can utilize the whole power supply cycle to complete the transmission of all data packets, thereby prolonging the working time. As shown in fig. 2d, after the 2 nd packet data packet transmission is started, a stage will be entered where the output voltage of the low dropout regulator and the input voltage of the signal transmitting element are both reduced, and although the output voltage of the low dropout regulator is reduced, the signal transmitting element 103 still keeps working because the lowest working voltage (U5) of the signal transmitting element 103 is reached, i.e. the signal can still be transmitted;
when the signal transmitting component 103 has consistent signal transmitting effect parameters (such as transmitting speed, packet loss rate, etc.) in the voltage range of 1.8V to 3.3V, since it is not necessary to use the high voltage transmitting range of the signal transmitting component 103, a low dropout linear regulator with an output voltage of 1.8V is selected, then in the stable stage of the output voltage of the output capacitor (i.e. the stable stage, the output voltage is stabilized to 1.8V), the signal transmitting component 103 will transmit the completed data packet, when the output voltage of the output capacitor drops below 1.8V due to the voltage drop of the energy storage capacitor in the energy storage component 102 and gradually drops (i.e. the dropping stage), the output voltage will be less than the lowest operating voltage of the signal transmitting component 103, so that the signal transmitting component 103 stops operating (as shown in fig. 2 c), therefore, the voltage of the signal transmitting assembly 103 during the signal transmitting period can be ensured to be constant, and the more stable signal transmitting effect caused by unnecessary loss (such as power consumption increase, device heating, signal transmitting speed reduction and the like caused by voltage fluctuation) caused by the fluctuation of the power supply voltage during the operation of the signal transmitting assembly 103 can be avoided. Specifically, when the model is actually selected, the low dropout linear regulator can adopt any one or a combination of the following LDO linear regulators: an LDO linear regulator model ME6206A33M3G (FIG. 3), an LDO linear regulator model ME6260A33XG (FIG. 4).
Of course, a peripheral circuit corresponding to the model of the LDO linear regulator should be further included, and those skilled in the art may match the corresponding peripheral circuit based on the specific model of the LDO linear regulator provided in the present disclosure, which is not described in detail in the present disclosure. It is worth noting that: in the prior art, in order to solve the technical problem of the present disclosure, a DCDC voltage-stabilized power supply (as shown in fig. 5, a circuit using a DCDC BUCK voltage reducer in the prior art) is used to perform voltage conversion between the self-generating motor and the signal transmitting component;
because the DCDC voltage-stabilized power supply is a switching power supply, pulse voltage/current always exists in a corresponding circuit, and further, when the equipment works, electromagnetic interference (see figure 6) is always emitted into the space to influence the emission of signals; in contrast, the first energy transfer component 104 of the present disclosure employs a low dropout linear regulator (LDO) with low ripple voltage, and since it is a linear power supply, there is no electromagnetic radiation problem (see fig. 7), and it can be seen from the comparison between fig. 6 and fig. 7 that the technical solution employed by the present disclosure reduces the BOM of PCB components and saves more cost compared to the DCDC solution employed in the prior art; it should be noted that the "1 st packet", "2 nd packet" and "3 rd packet" in fig. 6 or fig. 7 mean corresponding data packets when the signal transmitting component 103 transmits signals, for example, 4 packets of the same data packets will be transmitted in one signal transmission, and then the "1 st packet" represents the 1 st data packet, the 2 nd packet represents the 2 nd data packet, and so on.
In some embodiments, as shown in fig. 2b, the energy storage assembly 102 includes at least a first energy storage element 1021; the capacity of the first energy storage element 1021 is set to be less than or equal to 22uF, so that during one signal transmission process, the electric energy stored in the energy storage component 102At least half is used for the signal emitting component 103 to power. The basis is as follows: from the residual capacity formula:
Figure BDA0003547007190000111
in the formula, W1 is the residual capacity, C is the capacitance of the first energy storage element 1021, and U is the lowest output voltage of the first energy storage element 1021; it can be known that, under a certain U condition (generally, the working voltage of the signal transmitting assembly 103 is 1.8V), the smaller the capacitance value of the first energy storage element 1021 is, the less the residual electric quantity W1 is; and the PMOS tube Q1 works in a linear region, so that the consumed energy is W2 ═ I2RT ═ I (ir) ═ I × Δ U × T, Δ U is the voltage drop across the PMOS transistor Q1 in the first energy transfer assembly 104, so that the greater the voltage drop Δ U, the more energy consumed by the first energy transfer assembly 104 and the less energy available to the signal emitting assembly 103; in order to reduce the energy loss caused by the first energy transmission assembly 104, W1 (residual capacity) is set to be less than or equal to W (all the electric energy stored in the energy storage assembly 102 by one action of the self-generating motor 101), resulting in C being less than or equal to 22 uF. Therefore, when the capacity of the first energy storage element 1021 is set to be less than or equal to 22uF, at least half of the electric energy stored in the energy storage component can be used for supplying energy to the signal transmitting component 103. For example, as shown in fig. 2b, the first energy storage element 1021 is implemented as a capacitor C1; the transmitter 100 further includes a first rectifying component 105 electrically connected between the self-generating motor 101 and the energy storage component 102, for rectifying the electric energy generated by the self-generating motor 101 to charge the energy storage component 102; specifically, one end of the capacitor C1 is electrically connected to one end of the first rectifying component 105 and the S pole of the PMOS transistor Q1 in the first energy transfer component 104, and the other end of the capacitor C1 is electrically connected to the other end of the first rectifying component 105 and the ground, respectively, and is configured to be connected to two electrodes of the self-generating motor 101 through the first rectifying component 105 so as to receive the electric energy generated by the self-generating motor 101. In one embodiment, the first rectifying element 105 is implemented as a single rectifying elementImplemented as a full bridge rectifier circuit including diode D1, diode D2, diode D3, and diode D4 as shown in fig. 2 b; wherein the anode of the diode D1 is electrically connected to the cathode of the diode D4, the anode of the diode D2 is electrically connected to the cathode of the diode D3, the anode of the diode D3 and the anode of the diode D4 are electrically connected to one end of the capacitor C1 and the ground, the cathodes of the diode D1 and the diode D2 are electrically connected to the other end of the capacitor C1, one electrode of the self-generating motor 101 is electrically connected between the diode D1 and the diode D4, and the other electrode of the self-generating motor 101 is electrically connected between the diode D2 and the diode D3, so as to perform full-wave rectification on the electric energy generated by the self-generating motor 101 through the full-bridge rectification circuit, so that the electric energy generated by the action of the self-generating motor 101 in any direction can be used for charging the capacitor C1.
In a preferred embodiment, the capacitance of the capacitor C1 is set to 15uF, so that a better balance between the efficiency of the first energy transfer assembly 104 and the residual capacity of the energy storage assembly 102 is achieved, i.e. in case of a small residual capacity, the resulting energy loss of the first energy transfer assembly 104 is small.
In some embodiments, the signal transmitting component 103 comprises at least: a processing unit (MCU) 1031 and a signal transmitting unit (RF SOC) 1032; the signal transmitting unit 1032 is communicably connected to the processing unit 1031 to transmit a signal to the outside under the control of the processing unit 1031. The processing unit 1031 and the signal transmitting unit 1032 may be integrated into a whole, for example, an OOK radio frequency chip with a model of CMT2150L, as shown in fig. 8, when the self-generating motor 101 operates, an electric energy pulse is generated, and the electric energy pulse charges a capacitor C1, so that the voltage of the capacitor C1 gradually rises from 0V to about 5V to establish the voltage of the input end of the first energy transfer component 104, and then, through the adjustment of the first energy transfer component 104, a stable 3.3V voltage is output from the output end of the first energy transfer component 104 to be supplied to the signal transmitting component at the rear end, that is, the OOK radio frequency chip with the model of CMT2150L, after the OOK radio frequency chip is powered on, the operation direction of the self-generating motor 101 is determined by detecting the level of the corresponding IO port pin, and then, a signal is transmitted to the air based on the detection result (the wireless control message corresponding to the signal at least includes the preset transmission The device's own ID and key).
Of course, in other embodiments, the processing unit 1031 and the signal transmitting unit 1032 may be separately disposed, for example: the processing unit 1031 adopts an MCU chip with a model number of 8PE53M, the signal transmitting unit 1032 adopts an RF radio frequency chip with a model number of CC115L, and the two are communicatively connected through an SPI bus. Referring to fig. 9, the self-generating motor 101 generates electric energy pulses when it operates, the pulse of electrical energy charges the capacitor C1, causing the voltage of the capacitor C1 to gradually rise from 0V to around 5V, further establishing the voltage of the input end of the first energy transfer component 104, and outputting the stable 3.3V power supply rear end processing unit (8PE53M)1031 and the signal transmitting unit (CC115L)1032 from the output end of the first energy transfer component 104 through the voltage regulation effect of the first energy transfer component 104, the processing unit 1031 determines the action direction of the self-generating motor 101 by detecting the pin level of the corresponding IO port, and controlling the signal transmitting unit to transmit a signal to the air according to the judgment result (the wireless control message corresponding to the signal at least should include the preset ID number and key value of the transmitter 100). The skilled person may choose to integrate or not integrate the processing unit 1031 and the signal transmitting unit 1032 together based on specific usage requirements and scenarios, and the disclosure is not limited in particular.
In some embodiments, the transmitter 100 further includes a second energy transfer component (not shown) for turning down the supply voltage output by the first energy transfer component 104 to a voltage suitable for the digital and analog cores of the processing unit 1031, so as to provide a lower supply power for the digital and analog cores of the processing unit 1031. In this embodiment, the second energy transfer component is configured to further reduce the supply voltage output by the first energy transfer component 104 and supply the supply voltage to the digital and analog cores inside the processing unit 1031, so that energy consumption of the digital and analog cores of the processing unit 1031 is reduced, and an IO interface outside the processing unit 1031 is directly powered by the power supply provided by the first energy transfer component 104, so as to ensure that IO levels of communication between the external IO interface and other digital systems in the transmitter 100 are consistent. The second energy transfer component adjusts the supply voltage output by the first energy transfer component 104 by repeatedly switching through a switching element, so as to reduce the supply voltage and supply the supply voltage to the digital and analog cores of the processing unit 1031.
Further, in a preferred embodiment, the second energy transfer assembly includes a DCDC buck power supply; the DCDC step-down power supply is integrated in the processing unit 1031 inside the signal transmitting assembly 103, so that the overall size miniaturization of the processing unit 1031 can be ensured; illustratively, the signal emitting component 103 integrated with the second energy transfer component may be, for example, a BLE bluetooth chip of model ATM2201 (see fig. 10); of course, components such as an inductor (e.g., L3 in fig. 10) for configuring the DCDC step-down power supply, which cannot be integrated into the processing unit 1031, are directly electrically connected to a port of the processing unit 1031, and further communicate with the DCDC step-down power supply inside the processing unit 1031 through the port, referring to fig. 11, a partial specific circuit diagram of the ATM2201 chip corresponding to fig. 10 is given, and it can be known from fig. 11 that: when the self-generating motor 101 acts, electric energy pulses are generated, the electric energy pulses charge the capacitor C1, so that the voltage of the capacitor C1 gradually rises from 0V to about 5V, to establish the input voltage of the first energy transfer assembly 104, and then through the voltage regulation of the first energy transmission component 104, a stable 3.3V power is output from the output end of the first energy transmission component 104, and is supplied to the signal emission component 103 (i.e. the low power consumption Bluetooth chip ATM2201) at the rear end, the low-power-consumption bluetooth chip judges the action direction of the self-generating motor 101 by detecting the pin level of the corresponding IO port, and signals to the air through a bluetooth protocol based on the judgment result (a bluetooth broadcast packet corresponding to the signal at least includes a preset ID number and a preset key value of the transmitter 100 (for example, a transmitter of a plurality of keys is to be provided with a key value for each key)); please refer to fig. 11 for a specific circuit connection relationship between circuit elements in the peripheral circuit corresponding to the ATM2201 chip, which is not described herein again. In this embodiment, on the basis of the adjustment of the output voltage generated by the self-generating motor 101 by the first energy transfer component 104, the adjusted output voltage is continuously adjusted again by the second energy transfer component, so that the once adjusted output voltage is directly used for supplying power to the external IO port of the processing unit 1031, and the once adjusted output voltage is used for supplying power to the digital and analog cores inside the processing unit 1031, so that under the condition that it is ensured that the IO levels of the external IO port of the processing unit 1031 and the communication of other digital systems in the transmitter 100 are consistent, the energy consumption of the processing unit 1031 is reduced, and the purpose of reducing the overall energy consumption of the transmitter 100 is achieved.
In some embodiments, the transmitter 100 further includes a polarity identification component 106 (see fig. 2 b); which is electrically connected between the self-generating motor 101 and the signal transmitting assembly 103 and is used for identifying the voltage polarity of the electric energy generated by the self-generating motor 101. The signal transmitting component 103 is further configured to determine the polarity of the electric energy according to the output result of the polarity identifying component 106, and further determine the action direction of the self-generating motor 101, so that the signal transmitting component 103 can identify through the polarity identifying component 106 whether the self-generating motor 101 acts in a forward direction or resets in a reverse direction. Specifically, an input end of the polarity identification component 106 is electrically connected to a certain electrode of the self-generating motor 101 (for example, an anode, and an electrode that outputs a forward voltage when the self-generating motor 101 operates in a forward direction is used as the anode), and an output end of the polarity identification component 106 is electrically connected to a certain IO port of the processing unit of the signal transmission component 103, so that when the self-generating motor 101 operates in the forward direction, the polarity identification component 106 outputs a specified level to the IO port, and the processing unit 1031 in the signal transmission component 103 determines the operation direction of the self-generating motor 101 based on a determination result of a pin level of the IO port. Fig. 2b shows a circuit diagram of an embodiment of the polarity identification component 106, and it can be seen that the polarity identification component 106 at least comprises: the second rectifying component, the second energy storage element and the third impedance element; the second rectifying assembly is electrically connected between the self-generating motor 101 and the second energy storage element, and is used for rectifying part of electric energy generated by the self-generating motor 101 and then charging the second energy storage element, so that the second energy storage element outputs a voltage; the third impedance element is connected between the second energy storage element and the processing unit 1031 of the signal transmitting assembly 103, and is configured to divide the voltage output by the second energy storage element and output the divided voltage to the processing unit 1031; based on the specific circuit structure of the polarity identification module 106, when the self-generating motor 101 operates in a forward direction in response to an external trigger, a forward voltage pulse is generated, the forward voltage pulse is rectified by the second rectifying module and then charged to the second energy storage element, so as to generate a voltage on the second energy storage element, the voltage is divided by the third impedance element and then transmitted to the IO port of the processing unit 1031, and then the processing unit 1031 identifies a high level (i.e., the specified level) at the IO port, and then determines that the self-generating motor 101 operates in the forward direction; when the self-generating motor 101 is reversely reset in response to the removal of the external trigger, a reverse voltage pulse is generated, at this time, the polarity identification component 106 cannot output a high level, that is, the designated IO port of the processing unit 1031 cannot identify the designated level, and then the processing unit 1031 obtains a judgment that the self-generating motor 101 is reversely reset when being powered on and the designated IO port does not identify the designated level. In the above embodiment, the positive unidirectional conducting circuit formed by the second rectifying component is used as the polarity identification component 106, so that the characteristics of different polarities of the generated electric energy in the forward action and the reverse reset of the self-generating motor 101 are ingeniously utilized, and the positive unidirectional conducting circuit is matched, so that the detection signal is properly triggered, and the identification process of the generating polarity is realized. Taking a self-generating doorbell as an example, the specific use content of the polarity identification component 106 is described as follows: when a transmitter of the self-generating doorbell is pressed down by an external force (described as a forward action in this embodiment), the signal transmitting component is respectively set to default to an operating mode (at this time, the signal transmitting component receives a detection signal of a specified level from an output port of the polarity identification component), wherein the operating mode can be used for completing the activation of the signal transmitting component in the transmitter and the identification of a basic pressing action, and when the transmitter bounces from a pressed state (also described as a reverse reset in this embodiment), the signal transmitting component in the transmitter does not acquire the detection signal of the specified level (for example, a high level) through the polarity identification component, the signal transmitting component is set to enter another operating mode; and the other working mode completes the sending of signals from the transmitter to the receiver matched with the transmitter in the self-generating doorbell.
It is emphasized that the present invention is described in one of many ways for the convenience of description. For example, similar to the equivalent scheme of pressing the output to be a positive voltage and the reverse reset output to be a negative voltage, and matching with the negative unidirectional conducting circuit, because the equivalent design can be realized without creative labor under the teaching of the technical scheme of the present invention, the present invention belongs to the protection scope of the present invention, and the details are not repeated herein.
Preferably, the capacitance value of the second energy storage element is at most one tenth of the capacitance value of the first energy storage element 1021, so that most of the electric energy generated by one action of the self-generating motor 101 is used for the working function of the signal transmitting assembly 103, and a small part of the electric energy is used for polarity identification. In a specific embodiment, the second energy storage element is implemented as a capacitor, in particular as the capacitor C3 in fig. 2b, the second rectifying component is implemented as a forward conducting diode D5, and the third impedance element comprises a resistor R3 and a resistor R4; wherein the anode of the diode D5 is electrically connected to an electrode (e.g. the anode corresponding to N in fig. 2b) of the self-generating motor 101, and the cathode is electrically connected to one end of the capacitor C3, for connecting the self-generating motor with the capacitor C3The electric energy generated by the machine 101 during forward motion is rectified to charge the capacitor C3; one end of the capacitor C3 is connected with one end of the R3, and the other end of the capacitor C3 is grounded; the other end of the resistor R3 is connected with the resistor R4 in series and then is grounded; the other end of the resistor R3 is further electrically connected to a designated IO port of the processing unit 1031, and is used for dividing the voltage generated on the capacitor C3 and transmitting the divided voltage to the processing unit 1031. As shown in fig. 2b, when the self-generating motor 101 operates in the forward direction, a part of generated electricity charges the capacitor C3 through the diode D5, and the rest of the electricity charges the capacitor C1 in the energy storage module 102 through the diode D2 and the diode D4. Because the energy generated by the self-generating motor 101 charges the two capacitors at the same time, the peak voltage amplitudes generated on the capacitors are basically consistent. According to the capacitance energy formula (
Figure BDA0003547007190000151
W is the capacitance energy, C is the capacitance value of the capacitor, and U is the output voltage of the capacitor) to obtain: the distribution proportion of the electric quantity obtained by the energy storage component 102 and the polarity identification component 106 from the self-generating motor 101 is related to the capacitance values of capacitors (namely, a capacitor C1 and a capacitor C3) of two circuits, the energy storage component 102 is used as a main power supply loop and needs to obtain most of the electric quantity generated by the self-generating motor 101, so that the capacitor C1 obtains uF-level capacitance value; the polarity identifying component 106 only acts as a signal sampling circuit for the specified level and needs to draw less energy, so the capacitance C3 takes on nF-level capacitance. As shown in fig. 12 (the 1 st packet, the 2 nd packet, etc. in the figure represent corresponding data packets in a certain signal transmission process), the waveforms of the capacitor C1 and the capacitor C3 need to be divided by a third impedance element into U2 and then input to a designated IO of the processing unit 1031 in the signal transmission module 103 because the peak voltage U1 of the electric energy generated by the operation of the self-generating motor 101 is too large.
