[0026] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 , shows a vibration detection device, including a vibration detection module 110, a discharge module 130 and a main control module 150.

[0028] The vibration detection module 110 is used to store energy when vibration is detected, and output a first detection signal when the stored energy reaches a first threshold.

[0029] The discharge module 130 is connected to the vibration detection module 110. When the vibration detection module 110 detects that the vibration stops, the discharge module 130 releases energy, and outputs a second detection signal when the stored energy is released to a second threshold.

[0030] Among them, the first threshold and the second threshold are preset values. By adjusting the size of the first threshold and the second threshold, the output conditions of the first detection signal and the second detection signal can be adjusted, and then by configuring the output duration between the first detection signal and the second detection signal, the sensitivity of the vibration detection device for vibration detection is changed, thereby instructing the vibration detection device to perform vibration detection.

[0031] The main control module 150 is connected to the vibration detection module 110 and the discharge module 130 respectively, and is used to receive the first detection signal and the second detection signal, and generate a vibration signal according to the first detection signal and the second detection signal.

[0032] Specifically, refer to Figure 2 The main control module 150 includes at least one configuration terminal 211 . The configuration terminal 211 of the main control module 150 is connected to the discharge module 130 .

[0033] The main control module 150 is used to generate a corresponding sensitivity configuration signal according to an externally input sensitivity indication signal, and the configuration terminal 211 is used to transmit the sensitivity configuration signal to the discharge module 130 .

[0034] The discharge module 130 includes a discharge unit 310 connected to the configuration terminal, and the discharge unit is used to configure the speed at which the vibration detection module releases the stored energy according to the received sensitivity configuration signal.

[0035] In one possible implementation, see Figure 3 The number of configuration terminals includes two, the discharge module 130 includes two discharge units 131 and 133, and the main control module outputs a first sensitivity configuration signal and a second sensitivity configuration signal to the discharge unit 131 and the discharge unit 133 through the configuration terminal 211 and the configuration terminal 213 respectively.

[0036] For example, as shown in Table 1:

[0037] Table 1 Sensitivity levels

[0038]

[0039] As shown in Table 1, L in the table represents a low level, H represents a high level, IO port Vibration_Level1 and IO port Vibration_Level2 are two configuration terminals, the two configuration terminals are respectively connected to the discharge unit 131 and the discharge unit 133, and the sensitivity levels include default sensitivity, sensitivity 1, sensitivity 2, and sensitivity 3.

[0040] Therefore, when different levels are input to the configuration end, the parameters that determine the discharge rate of the discharge module are changed, and then the vibration detection sensitivity is changed to the corresponding sensitivity value, so as to achieve the effect of configuring the vibration detection sensitivity and improve the vibration detection efficiency. In a possible implementation, the sensitivity of vibration detection is changed by using a MOS tube switch, for example, connecting the IO port Vibration_Level1 through the MOS tube switch Q1 and connecting the IO port Vibration_Level2 through the MOS tube switch Q2.

[0041] When both Vibration_Level1 and Vibration_Level2 output low levels, the corresponding sensitivity is changed to the default sensitivity, the discharge module circuit does not change, and the discharge module discharge rate is the value corresponding to the default sensitivity.

[0042] When the sensitivity is adjusted from the default sensitivity to sensitivity 1, Vibration_Level1 outputs a high level and Vibration_Level2 maintains a low level, so that Q1 is turned on, the discharge unit 131 is connected to the circuit, the discharge module circuit is changed to the circuit corresponding to sensitivity 1, and the discharge module discharge rate is the value corresponding to sensitivity 1.

[0043] When the sensitivity is adjusted from the default sensitivity to sensitivity 2, Vibration_Level1 maintains a low level and Vibration_Level2 outputs a high level, so that Q2 is turned on, the discharge unit 133 is connected to the circuit, the discharge module circuit is changed to a circuit corresponding to sensitivity 2, and the discharge module discharge rate is the value corresponding to sensitivity 2.

[0044] When the sensitivity is adjusted from the default sensitivity to sensitivity 3, Vibration_Level1 and Vibration_Level2 both output high levels, so that Q1 and Q2 are both turned on, and discharge units 131 and 133 are both connected to the circuit, changing the discharge module circuit to a circuit corresponding to sensitivity 3, and the discharge module discharge rate is the value corresponding to sensitivity 3.

[0045] Therefore, a first detection signal is generated when the vibration detection module detects vibration, and a second detection signal is generated when the vibration detection module does not detect vibration. The output time length between the first detection signal and the second detection signal is changed to adjust the vibration detection sensitivity of the vibration detection module, thereby avoiding mutual interference between the vibration detection charging delay and the vibration amplitude detection and improving the accuracy of vibration detection.

[0046] In one possible implementation, the energy storage process is performed by charging the capacitor, and the energy release process is performed by discharging the capacitor. During the energy storage process and the energy release process, the amount of energy is determined by the voltage value of the capacitor, that is, the first threshold and the second threshold are preset voltage values. When the capacitor voltage value is greater than the first threshold, the first detection signal is output, and when the capacitor voltage value is less than the second threshold, the second detection signal is output.

[0047] It should be noted that the first detection signal and the second detection signal may be level signals output by the vibration detection module. For example, the vibration detection module outputs a low level signal as the first detection signal and outputs a high level signal as the second detection signal.

[0048] In an exemplary embodiment, if Figure 4 As shown, the discharge module 130 includes a discharge unit 131. The discharge unit 131 is connected to at least one configuration terminal of the main control module to obtain a sensitivity configuration signal sent by the main control module through each configuration terminal of the main control module. The discharge unit is used to configure the speed at which the vibration detection module releases the stored energy according to the received sensitivity configuration signal.

[0049] Specifically, the discharge unit 131 includes a first switch element 1311 and a discharge element 1313 .

[0050] The control end of the first switch element 1311 is used to receive a sensitivity configuration signal, and control the input end and the output end of the first switch element 1311 to be turned on or off according to the sensitivity configuration signal.

[0051] When the input and output ends of the first switch element 1311 are turned on, the discharge element 1313 is used to release the energy stored in the vibration detection module. When the input and output ends of the first switch element 1311 are turned off, the discharge element 1313 stops releasing the energy stored in the vibration detection module.

[0052] In a possible implementation, the discharge element is a resistor. When the vibration detection module detects that the vibration stops, the first switch element receives a sensitivity configuration signal and controls the input and output ends of the first switch element to be turned on based on the sensitivity configuration signal, so that the discharge element is connected to the circuit to release the energy stored in the vibration detection module and finally output a second detection signal. In the above process, the capacitor voltage drop rate in the discharge process can be controlled by adjusting the sensitivity of the vibration detection, thereby controlling the output time between the first detection signal and the second detection signal.

[0053] The circuit structure of the discharge unit 133 may be similar to or identical to that of the discharge unit 131 , and the resistance of the discharge element in the discharge unit 133 may be the same as or different from that of the discharge element in the discharge unit 131 .

[0054] In other embodiments, the number of configuration terminals of the main control module may be three, four or more, and correspondingly, the number of discharge units included in the discharge module may also be three, four or more. Each configuration terminal is connected to each discharge unit, respectively. By connecting different numbers of discharge units to the circuit in a non-passing form, the discharge process can be controlled at different rates, thereby achieving different sensitivity adjustments.

[0055] It should be noted that the inventors are aware that the prior art detects vibration by storing energy and performing charging delay, and determines whether vibration occurs through the energy storage process. However, since the frequency of the AC signal generated in the charging delay circuit changes during the energy storage process, the energy storage process is unstable, resulting in a decrease in the sensitivity of detecting the vibration amplitude. Therefore, by performing vibration detection through discharge delay, the interference caused by charging delay can be avoided, and the sensitivity and accuracy of vibration detection can be improved.

[0056] Based on the above circuit, vibration detection is implemented through the discharge unit, thereby improving the accuracy and efficiency of vibration detection.

[0057] In an exemplary embodiment, if Figure 5 As shown, the vibration detection module 110 includes a switch circuit 410 , a charging circuit 430 , and a vibration detection circuit 450 .

[0058] The vibration detection module 110 includes a switch circuit 410, a charging circuit 430, and a vibration detection circuit 450 connected to each other.

[0059] The vibration detection circuit 450 is used to generate a voltage jitter signal when vibration is detected.

[0060] The charging circuit 430 is used to receive the voltage jitter signal, charge and store energy according to the voltage jitter signal, and release the energy through the discharge module.

[0061] The switch circuit 410 is used to generate a first detection signal and a second detection signal according to the energy stored in the charging circuit, the first threshold and the second threshold during the process of charging and releasing energy of the charging circuit, and transmit the first detection signal and the second detection signal to the main control module.

[0062] The switch circuit 410 includes a third switch element 413 connected to the charging circuit and a detection signal output terminal 411 .

[0063] First, it is explained that the switch circuit 410 is used to output the first detection signal and the second detection signal according to the energy stored in the charging circuit, the first threshold and the second threshold respectively during the process of the charging circuit storing energy and the discharging module releasing energy.

[0064] The third switch element 413 is used to be turned on when the energy in the charging process of the charging circuit reaches a first threshold, or to be turned off when the energy in the energy releasing process of the charging circuit reaches a second threshold.

[0065] The detection signal output terminal 411 is used to generate a first detection signal when the third switch element is turned on, or to generate a second detection signal when the third switch element is turned off.

[0066] Among them, the third switch element is turned on when the energy in the charging circuit reaches a first threshold during the energy storage process, and controls the detection signal output end to output a first detection signal, or is turned off when the energy stored in the charging circuit reaches a second threshold during the energy release process of the discharge module, and controls the detection signal output end to output a second detection signal.

[0067] Secondly, the charging circuit 430 is used to receive the vibration signal and charge and store energy according to the vibration signal. In a possible implementation, see Figure 5 The charging circuit 430 includes an energy storage element 431 and a second switch element 433 .

[0068] The second switch element 433 is used to convert the output voltage of the vibration detection circuit into an energy storage voltage when receiving the voltage jitter signal, and to charge the energy storage element through the energy storage voltage.

[0069] The energy storage element 431 is used to store energy.

[0070] It should be noted that, when receiving the vibration signal, the charging circuit 430 converts the output voltage of the vibration detection circuit into an energy storage voltage, and outputs the energy storage voltage to the energy storage element via the second switch element for energy storage.

[0071] Next, it is explained that the vibration detection circuit 450 is used to output a vibration signal when vibration is detected.

[0072] In one possible implementation, see Figure 5 The vibration detection circuit 450 includes a vibration detection element 451 and a current limiting element 453 connected to the vibration detection element 451 .

[0073] The vibration detection element 451 is used to switch between on and off when vibration is detected.

[0074] In one possible implementation, when the vibration detection element does not detect that the vibration amplitude exceeds the vibration threshold for indicating the occurrence of vibration, the on or off state of the input and output ends of the vibration detection element remains unchanged; when the vibration amplitude is detected to be greater than the vibration threshold, it is determined that vibration has occurred and the on or off state of the input and output ends of the vibration detection element is switched.

[0075] In addition, the current limiting element 453 is used to generate a voltage jitter signal when the vibration detection element is switched between on and off, and transmit the voltage jitter signal to the charging circuit.

[0076] There may be multiple current limiting elements, which are connected in series, so that when the vibration detection element is turned on or off, a node at which the multiple current limiting elements are connected outputs a vibration signal.

[0077] In a possible implementation, when the vibration signal is a vibration detection element switching on or off, a voltage jitter is generated in the circuit, and energy is stored in the energy storage element in the charging circuit through the voltage jitter.

[0078] In a possible implementation, the number of current limiting elements 453 includes two, including a first current limiting element and a second current limiting element. One end of the first current limiting element is used to connect to the power supply end, and one end of the second current limiting element is connected to the vibration detection element. The other end of the first current limiting element is connected in series with the other end of the second current limiting element, and a voltage jitter signal is generated at the node where the first current limiting element and the second current limiting element are connected in series.

[0079] Figure 6 This is a schematic diagram of a specific implementation of a vibration detection device in an application scenario. Figure 6 In the embodiment, the vibration detection device is composed of a main control, a switch circuit, an energy storage circuit, a discharge circuit, a charging circuit and a vibration detection circuit. Among them, the vibration detection circuit is a vibration sensor S1, the energy storage circuit is composed of a capacitor C5 and a resistor R3, the switch circuit is composed of a MOS tube switch Q3 and an IO port Vibration_INT, the discharge circuit is composed of MOS tube switches Q1 and Q2 connected to the IO port Vibration_Level1 and the IO port Vibration_Level2 respectively, and the charging circuit is composed of a capacitor C4 and a diode D1.

[0080] When the vibration detection circuit detects the occurrence of vibration, it generates voltage jitter in the circuit by continuously turning on and off the vibration sensor S1. At this time, the voltage jitter charges the capacitor C5 in the energy storage circuit through the capacitor C4 and the diode D1 in the charging circuit. Among them, the charging capacitance value of the capacitor C5 is a capacitance value that can be fully charged by one energy storage, that is, as long as the vibration detection module detects a vibration, the capacitor can be fully charged at one time, and the energy storage voltage is maintained at a stable maximum value. When the energy in the energy storage circuit reaches the first threshold, the switch circuit turns on the MOS tube switch Q3 and outputs the first detection signal through the IO port Vibration_INT.

[0081] When the vibration detection circuit detects that the vibration stops, the vibration sensor S1 stops changing the state, the voltage jitter disappears, the charging circuit stops charging the energy storage circuit, and the main control obtains the sensitivity information configured by the user and outputs the signal corresponding to the sensitivity through the IO port Vibration_Level1 and IO port Vibration_Level2. The discharge circuit configures the on and off of the MOS tube switches Q1 and Q2 by detecting the output signals of the IO port Vibration_Level1 and IO port Vibration_Level2, so that as shown in Table 2, the discharge time constant of the discharge circuit corresponds to the configured sensitivity. The energy storage circuit discharges by forming a discharge loop with the discharge circuit, and the discharge rate is determined by the discharge time constant of the discharge circuit. When the energy in the energy storage circuit reaches the second threshold, the switch circuit turns off the MOS tube switch Q3 and outputs the second detection signal through the IO port Vibration_INT.

[0082] Table 2

[0083]

[0084]

[0085] It should be noted that in other application scenarios, the energy storage circuit and the charging circuit can also be combined together, that is, the shared capacitor C5, so as to facilitate charging and energy storage when the vibration detection module detects vibration, and cooperate with the discharge module to release energy when the vibration detection module detects that the vibration stops. This does not constitute a specific limitation here.

[0086] Based on the above circuit, the vibration detection energy storage process is controlled and the energy release process is stabilized, thereby achieving the effect of improving the vibration detection accuracy.

Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

[0088] The above description is only a partial implementation mode of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
