The crystal oscillator and the second clock capacitor are connected in series with each other, the capacitance value of the first clock capacitor is consistent with the capacitance value of the second clock capacitor, the crystal oscillator is used to generate a low-precision clock signal through vibration, and the first clock capacitor and the second clock capacitor are both used to stabilize the vibration frequency of the crystal oscillator; the control module includes a drain and a gate, the drain is connected to the other end of the second clock capacitor, and the gate is connected to the other end of the first clock capacitor, which can simplify the crystal oscillator circuit of the low-power wireless remote control, improve the clock accuracy and stability of the crystal oscillator circuit, thereby increasing the service life of the wireless remote control, while also improving the integration of the internal system of the wireless remote control and reducing the production cost.
[0033] Therefore, the embodiments of the present invention are further described below in conjunction with the accompanying drawings.
[0034] Reference Figure 1 As shown, Figure 1 It is an overall structural diagram of a low-power wireless remote control provided by some embodiments of the utility model. The low-power wireless remote control includes a clock signal module 100 and a control module 200. The control module 200 is connected to the clock signal module 100. The clock signal module 100 is used to generate a stable clock signal. The control module 200 is used to process the clock signal of the clock signal module 100. The clock signal module 100 includes a crystal oscillator X2, a first clock capacitor C4 and a second clock capacitor C3. The capacitance value of the first clock capacitor C4 is consistent with the capacitance value of the second clock capacitor C3. The crystal oscillator X2 is used to generate a low-precision clock signal by vibration. The first clock capacitor C4 and the second clock capacitor C3 are both used to stabilize the vibration frequency of the crystal oscillator X2.
[0035] It should be noted that the capacitance of the first clock capacitor C4 or the second clock capacitor C3 is determined by the crystal load capacitance of the crystal oscillator X2 and the stray capacitance of the circuit board, that is, the capacitance of the first clock capacitor C4 or the second clock capacitor C3 can be the sum of the capacitance of the crystal load capacitance and the capacitance of the stray capacitance, and this application does not make specific limitations.
[0036] Among them, one end of the crystal oscillator X2 is connected to one end of the first clock capacitor C4, the other end of the crystal oscillator X2 is connected to one end of the second clock capacitor C3, the first clock capacitor C4 and the second clock capacitor C3 are connected in parallel to each other, the crystal oscillator X2 and the first clock capacitor C4 are connected in series to each other, and the crystal oscillator X2 and the second clock capacitor C3 are connected in series to each other. The control module 200 includes a drain XT1 and a gate XT2, the drain XT1 is connected to the other end of the second clock capacitor C3, and the gate XT2 is connected to the other end of the first clock capacitor C4.
[0037] It should also be noted that the first clock capacitor C4 and the second clock capacitor C3 provide frequency deviation adjustment for the control module 200. By adjusting the capacitance of the first clock capacitor C4 or the second clock capacitor C3, the clock signal frequency, clock signal power consumption and clock signal oscillation capability generated by the clock signal module 100 can be changed, thereby ensuring that when the ambient temperature of the low-power wireless remote control changes greatly, the signal of the clock signal module 100 works close to the frequency center point, so that the generated clock signal is as close to the target frequency as possible, thereby ensuring that the clock signal of the low-power wireless remote control will not change with changes in the operating voltage or ambient temperature, so that the operating frequency of the low-power wireless remote control tends to be stable.
[0038] Further, refer to Figure 1 As shown, the clock signal module 100 also includes a first clock resistor R13, which is used to protect the clock signal module 100. One end of the first clock resistor R13 is connected to one end of the crystal oscillator X2, and the other end of the first clock resistor R13 is connected to the control module 200. The first clock resistor R13 and the crystal oscillator X2 are connected in series with each other, and the first clock resistor R13 and the first clock capacitor C4 are connected in series with each other, thereby ensuring that the clock signal module 100 avoids the situation where the excitation voltage is too high or the excitation current is too large in the oscillation circuit, that is, it can prevent the irreversible damage to the crystal oscillator X2 due to excessive excitation power.
[0039] Further, refer to Figure 1As shown, the clock signal module 100 also includes a second clock resistor R12, and the second clock resistor R12 is used to gain the clock signal generated by the clock signal module 100. One end of the second clock resistor R12 is connected to one end of the first clock resistor R13, and the other end of the second clock resistor R12 is connected to the drain. The second clock resistor R12 and the crystal oscillator X2 are connected in parallel, and the second clock resistor R12 and the first clock resistor R13 are connected in series, so that when the interference signal is weak, it can ensure that the crystal oscillator circuit of the clock signal module 100 obtains signal gain, that is, the circuit negative impedance (-R) of the clock signal module 100 is increased, and the start-up time of the crystal oscillator X2 is shortened, so that the crystal oscillator X2 is easier to start.
[0040] It should be noted that the vibration frequency of the crystal oscillator X2 is 32.768KHz, the capacitance of the first clock capacitor C4 is 12.5PF, the capacitance of the second clock capacitor C3 is 12.5PF, the resistance of the first clock resistor R13 is 100Ω to 1KΩ, and the resistance of the second clock resistor R12 is 10MΩ.
[0041] Further, refer to Figure 2 As shown, Figure 2 It is a structural diagram of the communication module of the low-power wireless remote control provided by some embodiments of the utility model.

One end of the first communication resistor R2 serves as an access end for an external power supply. One end of the first communication resistor R2 is connected to the negative electrode of the photodiode TR1. The positive electrode of the photodiode TR1 is connected to the collector of the transistor Q1. The collector of the transistor Q1 is connected to one end of the second communication resistor R1. The emitter of the transistor Q1 serves as a ground terminal. The other end of the second communication resistor R1 is connected to the control module 200, so that the corresponding optical signal can be sent to and received from the external electrical appliance through the photodiode TR1, thereby improving the wireless communication capability between the low-power wireless remote control and the external electrical appliance.
[0042] Further, refer to Figure 3 As shown, Figure 3It is a structural diagram of the key module of the low-power wireless remote control provided by some embodiments of the utility model. The low-power wireless remote control also includes a key module 400. The key module 400 is used to send an electrical signal to the control module 200. The key module 400 is connected to the control module 200. The key module 400 includes a plurality of first machine keys K (such as: the first machine key K1 to the first machine key K22). The plurality of first machine keys K are interconnected in a matrix manner, thereby being able to provide different remote control instructions for the low-power wireless remote control, thereby improving the versatility of the low-power wireless remote control.
[0043] Further, refer again Figure 1 The low-power wireless remote control also includes a cold start reset module 500. The cold start reset module 500 is used for the control module 200 to send an electrical signal requesting a reset. The cold start reset module 500 is connected to the control module 200. The cold start reset module 500 includes a second machine button RESET, a reset capacitor C5 and a reset resistor R4. One end of the reset resistor R4 is respectively connected to the control module 200, one end of the second machine button RESET, and one end of the reset capacitor C5. The other end of the second machine button RESET is grounded, and the other end of the reset capacitor C5 is grounded. The second machine button RESET and the reset capacitor C5 are connected in parallel with each other, so that the low-power wireless remote control can be quickly reset.
[0044] Further, from Figure 1 It can be seen that the low-power wireless remote control also includes a power module 600, which is used to power the low-power wireless remote control. The power module 600 includes a first power supply potential CON1, a second power supply potential CON2, a power supply resistor R5, a first power supply capacitor C1 and a second power supply capacitor C2.
