Referring to fig. 1, fig. 1 is a schematic structural diagram of a device according to a first embodiment of the vibration wake-up system of the present invention, which provides the first embodiment of the present invention.
As shown in fig. 1, in this embodiment, the vibration wake-up system includes: a vibration detection module 10 and a control module 20.
The vibration detection module 10 is connected with the control module 20, and the control module 20 is connected with an external tire pressure detection system.
The vibration detection module 10 is a module for detecting the vibration of the vehicle door and transmitting the detection result. The vibration detection module 10 may detect the vibration of the door in the X-axis and the Y-axis of the door by using a sensor including three-axis detection.

It should be appreciated that, in order to avoid wasting resources, the external tire pressure monitoring system enters a deep sleep state when the vehicle is parked for more than a certain time, for example, when the vehicle is stopped for more than one minute, the external tire pressure monitoring system actively enters the deep sleep state.
In a specific implementation, when the external tire pressure detecting system enters a deep sleep state, the vibration detecting module 10 of the vibration wake-up system detects the vibration condition of the vehicle door.

Based on the foregoing the utility model discloses a first embodiment provides the utility model discloses a second embodiment.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a device according to a second embodiment of the vibration wake-up system of the present invention.
As shown in fig. 2, in the present embodiment, the vibration detection module 10 includes: a vibration detection chip U1, a first power supply circuit 101, and a second power supply circuit 102; the vibration detection chip U1 is connected to the first power supply circuit 101, the second power supply circuit 102, and the control module 20, respectively.
The vibration detection chip U1 is a chip for detecting vibration of the vehicle door. The vibration detection chip U1 may be a sensor chip, and the vibration detection chip U1 may detect movement of the vehicle door in different directions to determine a vibration condition of the vehicle door, may also detect gravity data of a position of the vehicle door to determine a vibration condition of the vehicle door, and may of course be in other manners, which is not specifically limited herein. In this embodiment, an SC7a20 chip may be taken as an example, the SC7a20 chip may obtain position information of the vehicle door in three axial directions, and the control module 20 may determine a vibration condition of the vehicle door through a change of the position information of the vehicle door, so as to wake up the external tire pressure detection system.
In a specific implementation, the vibration detection module 10 may generate a reference electrical signal according to parking space position information collected when the vehicle is parked for more than a certain time, and send the generated reference electrical signal to the control module 20. The vibration detection chip U1 acquires a door position electric signal when detecting the vibration in the vehicle, and generates the interrupt signal when acquiring the door position electric signal. The transmission of the door inner position signal may be powered by the first power supply circuit 101, the vibration detection chip U1 transmitting the door position electrical signal and the second power supply circuit 102 powering the clock signal transmitting the door position electrical signal. The termination signal may be sent directly to the control module 20 by the vibration detection chip U1.
In this embodiment, the vibration detection module 10 further includes: a first regulator circuit 103 and a second regulator circuit 104; the first voltage stabilizing circuit 103 is connected with the vibration detection chip U1, and the second voltage stabilizing circuit 104 is connected with the vibration detection chip U1.
The first voltage regulator circuit 103 is a circuit for supplying a stable voltage to the vibration detection chip U1. The vibration detection chip U1 is directly connected to the power source VCC, and when the voltage inside the vibration detection chip U1 fluctuates, the voltage inside the vibration detection chip U1 may fluctuate, so as to avoid the influence of the fluctuation of the power source VCC on the vibration detection chip U1, and to stabilize the input voltage of the vibration detection chip U1. The second voltage regulator circuit 104 is a circuit for regulating the voltage in the vibration detection chip U1.
In a specific implementation, the first voltage regulator circuit 103 may regulate an input voltage of the vibration detection chip U1, i.e., an output voltage of the power supply VCC, so that the power supply VCC provides a stable input voltage for the vibration detection chip U1. The second voltage stabilizing circuit 104 can stabilize the voltage inside the vibration detection chip U1 to determine the voltage inside the vibration detection chip U1 to be stable, thereby avoiding the influence on the detection of the vehicle door, the data transmission, and the like.
In this embodiment, the first power supply circuit 101 includes: a power supply VCC and a first pull-up resistor R1.
The power source VCC is connected to a first end of the first pull-up resistor R1, and a second end of the first pull-up resistor R1 is connected to the vibration detection chip U1 and the control module 20, respectively.
It should be noted that the pull-up is to clamp the indeterminate signal at a high level through a resistor, which is a pull-up resistor. The pull-up resistor can play a role in limiting current at the same time. When the external component is not connected, the external component is high impedance with respect to the input terminal of the external component. At this time, the voltage at the input port can be pulled up to a high level by the pull-up resistor. If the external component is enabled, it will remove the high level set by the pull-up resistor. By doing so, the pull-up resistor can maintain the pin at a certain logic level even when an external component is not connected. In this embodiment, the first pull-up resistor R1 may maintain the information transmitting terminal of the vibration detection chip U1 in a high state. The power source VCC may be shunted through a first pull-up resistor R1 to provide power for the transmission of the door position electrical signal.
In a specific implementation, in the case of no door position electrical signal transmission, the power source VCC and the first pull-up resistor R1 may set the output terminal of the vibration detection chip U1 to a high level. In order to ensure that the door position electrical signal can be transmitted smoothly when the door position electrical signal needs to be transmitted, the power source VCC and the first pull-up resistor R1 may provide energy for the transmission of the door position electrical signal.
In this embodiment, the second power supply circuit 102 includes: a second pull-up resistor R2; a first end of the second pull-up resistor R2 is connected to the power VCC, and a second end of the second pull-up resistor R2 is connected to the vibration detection chip U1 and the control module 20, respectively.
The second pull-up resistor R2 is a resistor for setting the clock signal output terminal of the vibration detection chip U1 to a high level. The connection of the second pull-up resistor R2 to the power supply VCC may provide energy for the transmission of the clock signal. The vibration detection chip U1 may provide a clock signal for door position electrical signaling when the door position electrical signaling is sent.
In a specific implementation, in the case of no door position electrical signal transmission, the vibration detection circuit does not need to provide a clock signal, and the output end of the clock signal can be set to a high state through the second pull-up resistor R2. Of course, when the clock signal is required for other functions of the vibration detection chip U1, the output point of the clock signal may be set to a low level, for example, in the process of collecting the door position information. Under the condition that no electric signal of the position of the vehicle door is sent, the vibration detection circuit can provide a clock signal for sending the electric signal of the position of the vehicle door, and the power supply VCC is connected with the second pull-up resistor R2 to provide energy for the clock signal.
In this embodiment, the first stabilizing circuit 103 includes: a first capacitance C1; the first end of the first capacitor C1 is respectively connected with the power supply VCC and the vibration detection chip U1, and the second end of the first capacitor C1 is grounded.
The first capacitor C1 is a capacitor for stabilizing the voltage of the power source VCC. The capacitor needs a certain time to charge and discharge, and the voltage at the two ends of the capacitor cannot change suddenly. When it is connected in parallel to the DC circuit, the capacitor is charged when the voltage is higher than the voltage of the capacitor and discharged when the voltage is lower than the voltage of the capacitor, so that the voltage on the circuit is smoother than that on the input end. According to the characteristic of the capacitor, the first capacitor C1 can stabilize and stabilize voltage fluctuation, so that the voltage stabilizing effect is better and the ripple is smaller.
In a specific implementation, the first end of the first capacitor C1 is connected to the power source VCC and the vibration detection chip U1, and the power source VCC supplies a voltage to the vibration detection chip U1 and charges the first capacitor C1, so that the voltage across the first capacitor C1 is the same as the voltage of the power source VCC. When the voltage supplied by the power source VCC fluctuates, the first capacitor C1 may regulate the input voltage of the vibration detection chip U1 in a charging or discharging manner. For example, when the voltage supplied from the power source VCC decreases due to fluctuation, the first capacitor C1 is discharged to supplement the voltage with the fluctuation, so as to stabilize the input voltage of the vibration detection chip U1.
In this embodiment, the second stabilizing circuit 104 includes: a second capacitance C2; the first end of the second capacitor C2 is connected with the vibration detection chip U1, and the second end of the second capacitor C2 is grounded.
The second capacitor C2 is a capacitor for stabilizing the voltage inside the vibration detection chip U1. The voltage stabilizing principle of the second capacitor C2 is as described in the first capacitor C1, and will not be described herein.
In a specific implementation, the power VCC may charge the second capacitor C2 through the vibration detection chip U1, so that the voltage across the second capacitor C2 is the same as the voltage inside the vibration detection chip U1, when the voltage inside the vibration detection chip U1 fluctuates, the second capacitor C2 may stabilize the voltage inside the vibration detection chip U1 through a discharging or charging manner, for example, when the power VCC inside the vibration detection chip U1 rises due to the fluctuation, the voltage across the second capacitor C2 may be charged by the internal voltage of the vibration detection chip U1 exceeding the voltage across the second capacitor C2, so as to stabilize the voltage inside the vibration detection chip U1.
In this embodiment, the control module 20 includes: a control chip U2, a power supply circuit 201 and a setting circuit 202;
the control chip U2 is connected to the second end of the first pull-up resistor R1, the second end of the second pull-up resistor R2, and the vibration detection chip U1, and the control chip U2 is further connected to the power supply circuit 201 and the setting circuit 202.
The control chip U2 is a chip for controlling the start of the external tire pressure detecting system according to the interrupt signal and the door position electrical signal. The control chip U2 may wake up the external tire pressure detection system by generating and transmitting an enable signal. In the present embodiment, the control chip U2 may be exemplified by an Rb33P165ALL chip. The power supply circuit 201 is a circuit for supplying a stable voltage to the control chip U2. The setting circuit 202 is a circuit that sets the tire air pressure condition in the tire air pressure detecting system. The tire pressure condition may be information on the corresponding air pressure, temperature, etc. of the tire. The tire pressure condition may be set after the tire pressure detection system is awakened, or may be preset and stored.
In specific implementation, the power supply circuit 201 supplies power to the control chip U2 to enable the control chip U2 to be in a working state, when the control chip U2 receives the door position electrical signal and the interrupt signal, determines a reference electrical signal according to the received interrupt signal, generates an enable signal according to the output of the comparison module by using the comparison module between the door position electrical signal and the reference electrical signal, and sends the enable signal to the external tire pressure detection system to wake up the external tire pressure detection system. For example, when receiving the door position electrical signal and the interrupt signal, the control chip U2 extracts a reference electrical signal according to the interrupt signal, and passes the door position electrical signal and the reference electrical signal through a comparator, generates an enable signal when the difference between the door position electrical signal and the reference electrical signal exceeds a certain threshold, and sends the enable signal to the external tire pressure detection system, so as to wake up the external tire pressure detection system. The enable signal may be one signal or a plurality of signals. For example, the control chip U2 may generate a display enable signal to wake up a display module of the tire pressure detecting system; generate the voice enable signal and awaken the voice broadcast module of tire pressure detecting system when tire pressure is unusual, certainly under the condition that tire pressure does not have the anomaly, can make the voice broadcast module continue to be in the state of sleeping deeply.
In this embodiment, the power supply circuit 201 includes: a third capacitance C3;
the first end of the third capacitor C3 is respectively connected with the power VCC and the control chip U2, and the second end of the third capacitor C3 is grounded.
The third capacitor C3 is a capacitor for stabilizing the voltage of the control chip U2. The third capacitor C3 has the same function as the first capacitor C1, and will not be described herein.
In a specific implementation, the first end of the third capacitor C3 is connected to the power source VCC and the control chip U2, respectively, and the power source VCC provides a voltage for the control chip U2 and charges the third capacitor C3, so that the voltage across the third capacitor C3 is the same as the voltage of the power source VCC. When the voltage supplied by the power source VCC fluctuates, the third capacitor C3 may regulate the input voltage of the vibration detection chip U1 in a charging or discharging manner.
In this embodiment, the setting circuit 202 includes: a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first flip-flop SW1, a second flip-flop SW2, and a third flip-flop SW 3.
A first end of the third resistor R3 is connected to the power VCC, a second end of the third resistor R3 is connected to the control chip U2, a first end of the fourth resistor R4, a first end of the fifth resistor R5 and a first end of the sixth resistor R6, a second end of the fourth resistor R4 is connected to the first end of the first flip-flop SW1, a second end of the fifth resistor R5 is connected to the first end of the second flip-flop SW2, a second end of the sixth resistor R6 is connected to the first end of the third flip-flop SW3, and a second end of the first flip-flop SW1, a second end of the second flip-flop SW2 and a second end of the third flip-flop SW3 are grounded.
It should be noted that the third resistor R3 is a voltage dividing resistor for stepping down the voltage of the power source VCC to set the tire pressure condition in the tire pressure detecting system. The fourth resistor R4, the fifth resistor R5, and the sixth resistor R6 are used to divide the voltage of the third resistor R3 to provide different voltages for setting the tire pressure condition. The tire pressure is set for the tire pressure condition at the control chip U2, and different conditions of the tire pressure detecting system of different voltage control settings are input. The first flip-flop SW1 is a flip-flop that controls whether or not the fourth resistor R4 performs voltage drop. Similarly, the second flip-flop SW2 is a flip-flop for controlling whether the fifth resistor R5 performs voltage drop; the third flip-flop SW3 is a flip-flop that controls whether or not the sixth resistor R6 performs voltage drop. Under the condition of triggering of different triggers, the resistors which are cooperatively stepped down with the third resistor R3 are different, so that the voltage of the power supply VCC input control chip U2 is different.
In a specific implementation, after the external tire pressure detecting system is awakened, the voltage output of the setting circuit 202 may also be controlled by the trigger, so as to control the setting of the tire pressure condition in the external tire pressure detecting system. For example, when the first trigger SW1 is triggered, the voltage between the third resistor R3 and the fourth resistor R4 is input to the control chip U2, so that the minimum tire pressure condition of the external tire pressure monitoring system can be set, and the minimum tire pressure condition can be displayed through the display module of the external tire pressure monitoring system.
