Detailed Description
The most traditional anti-theft means for the two-wheeled electric vehicle is manual locking by a chain; obviously, the anti-theft means brings great inconvenience to users; and if the user forgets to lock the vehicle when leaving, the same risk of theft exists.
Therefore, in order to avoid the situation that the user forgets or is inconvenient to lock the vehicle, the technical scheme that the mobile terminal such as a mobile phone of the user can be automatically sensed by using the Bluetooth communication function and the alarm is automatically started when the mobile terminal such as the mobile phone leaves is provided, so that the safety of the two-wheeled electric vehicle is improved to a certain extent.
In order that those skilled in the art will better understand the disclosure, the utility model will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a control circuit of a two-wheeled electric vehicle according to an embodiment of the present application, and fig. 2 is a schematic diagram of a circuit structure of a bluetooth controller according to an embodiment of the present application.
The two-wheeled electric vehicle control circuit may include:
as for the bluetooth controller U1 on the vehicle body; the vehicle speed detection circuit 10 is connected with the Bluetooth controller U1; the vibration detection circuit 20 is connected with the Bluetooth controller U1; the alarm 30 is connected with the Bluetooth controller U1;
the vehicle speed detection circuit 10 is used for detecting the wheel rotation condition of the vehicle body to obtain a vehicle speed signal;
the vibration detection circuit 20 is used for sensing and detecting the vibration condition of the two-wheeled electric vehicle to obtain a vibration signal;
the bluetooth controller U1 is used for outputting a start alarm signal to the alarm 30 if the vehicle speed signal is greater than the set vehicle speed threshold and/or the vibration signal is greater than the set vibration threshold when the mobile terminal is not detected through wireless bluetooth.
The alarm 30 may include a buzzer, LED lights, etc. connected to the bluetooth controller U1.
It can be understood that when the two-wheeled electric vehicle is normally parked, the wheels do not rotate, the speed of the vehicle is 0, and severe vibration does not exist; if the vehicle is moved manually, the vehicle is easy to vibrate, and therefore the vibration signal detected by the vibration detection circuit is overlarge.
In addition, when the electric vehicle is in a parking state, the driving motor for driving the wheels to rotate is generally in a power-off state; however, as long as the wheels of the electric vehicle are not locked manually, the vehicle can still be pushed manually to rotate the wheels, so that the rotation speed of the wheels of the vehicle is caused.
Therefore, the vehicle speed detection circuit is further arranged to detect the rotating speed of the wheels, and when the wheels have a certain rotating speed, the possibility of being manually pushed or slipping can be considered.
On the basis that the vibration detection circuit 20 and the vehicle speed detection circuit 10 respectively detect the vibration condition and the wheel rotation condition of the vehicle, the present embodiment further provides a bluetooth controller U1 connected to the vibration detection circuit 20 and the vehicle speed detection circuit 10. Referring to fig. 2, the bluetooth controller U1 in the present application may employ a LE5010 chip. The main function of the bluetooth controller U1 is to detect the sensing mobile terminal 01 using its own wireless bluetooth function. The mobile terminal 01 in this embodiment mainly refers to a mobile phone that a user can carry with; of course, a specially configured electronic key that interacts with the bluetooth controller U1 within close proximity is also contemplated. The Bluetooth controller U1 detects the mobile terminal 01 through induction as a basis for judging whether the user leaves the electric vehicle or not; when the mobile terminal 01 is not detected, threshold comparison is performed on the vibration signal and the vehicle speed signal respectively output by the vibration detection circuit 20 and the vehicle speed detection circuit 10, and once one of the signals exceeds the corresponding threshold, the alarm 30 is triggered to start alarming.
Based on the above discussion, it can be determined that, in the present application, the bluetooth controller U1 with a bluetooth function is used, active sensing detection of the mobile terminal 01 within a certain area range can be achieved, the mobile terminal 01 is not detected as a trigger signal for alarm, and the alarm 30 is triggered to alarm when the vehicle shakes due to the rotation speed of the wheel, so that no manual operation is required, and the risk of vehicle theft is avoided to a certain extent due to the fact that the user forgets to lock the vehicle.
On the basis, as for the bluetooth controller U1 in the present embodiment, although there is a software running program that compares the magnitude of the vehicle speed signal and the vibration signal and determines whether to trigger an alarm according to the comparison result. However, it is obvious that for a controller chip or a processor chip, when a trigger signal (i.e. a signal of the mobile terminal is not detected) is obtained, the two received data are respectively compared with the corresponding thresholds, wherein one of the two received data exceeds the threshold, i.e. a corresponding signal is output, which belongs to the conventional software program function that can be realized by the existing controller chip, and the software program executed by the controller chip does not belong to the improvement in the present application, and the key in the present application is that the controller chip with this function is adopted to cooperate with the vehicle speed detection circuit 10 and the shock detection circuit 20, so as to jointly realize the technical scheme of automatically starting the vehicle alarm without manually locking the vehicle.
In addition, it can be understood that, when the mobile terminal 01 is an electronic device such as a mobile phone carried by a user, the bluetooth controller U1 and the mobile terminal 01 of the user may be bound in advance by using a wireless communication function of the bluetooth controller U1, and for a specific binding manner, reference may be made to a conventional technology for binding two electronic devices to each other, which is not described in detail in this embodiment.
To sum up, utilize the bluetooth controller can auto-induction mobile terminal's such as cell-phone function in this application, and combine speed of a motor vehicle detection circuit and vibrations detection circuit to detect the speed of a motor vehicle and the vibrations condition respectively, and can't respond to at the bluetooth controller and detect corresponding mobile terminal, and speed of a motor vehicle signal and vibration signal are too big, trigger the alarm and report to the police, make two-wheeled electric motor car under the state of berthhing, need not manual operation and can realize the burglar alarm to two-wheeled electric motor car, the security of electric motor car has been promoted to a certain extent, and bring the convenience for the use of electric motor car.
Based on the foregoing embodiment, referring to fig. 3, fig. 3 is a schematic structural diagram of a vehicle speed detection circuit provided in an embodiment of the present application, and in another optional embodiment of the present application, the vehicle speed detection circuit 10 may include:
the circuit comprises an electromagnetic sensor U2, a first resistor R1, a second resistor R2, a third resistor R3, a first diode D1, a first capacitor C1 and a first triode Q1;
the electromagnetic sensor U2 is arranged on the wheel motor and used for sensing a rotating speed signal of the wheel shaft relative to the motor coil.
For two-wheeled electric vehicles, the basic principle of wheel rotation is to connect the main shaft of the driving motor with the wheel shaft of the wheel, and when the coil in the driving motor is energized, the main shaft of the driving motor can be controlled to drive the wheel shaft of the wheel to rotate, so as to drive the whole wheel to rotate.
But when the electric motor car was in the parking state, driving motor was in the off-electricity state, if the people for this moment promoted the electric motor car or appeared the swift current car and lead to the wheel to rotate, just also make the shaft of wheel drive driving motor's main shaft rotatory, driving motor converts the generator to a certain extent, therefore, can set up magnetic sensor U2 such as hall sensor on driving motor, it is rotatory to lock driving motor's main shaft, electromagnetic sensor U2 also can detect the magnetic field of sensing the change, and then produce the magnetic field that changes along with the magnetic field change. Taking the hall sensor as an example, the output of the hall sensor is generally a pulse square wave signal, and obviously, the signal period of the pulse square wave signal is proportional to the wheel rotating speed. Therefore, the vehicle speed of the wheel can be determined by only determining the pulse number of the pulse square wave signal received in unit time.
For this reason, the vehicle speed detecting circuit 10 in the present embodiment may further include:
the output end of the electromagnetic sensor U2 is connected with the first end of a first resistor R1, the second end of a first resistor R1 is connected with the first end of a second resistor R2, the cathode end of a first diode D1, the first end of a first capacitor C1 and the base of a first triode Q1; a second end of the second resistor R2, an anode end of the first diode D1, a second end of the first capacitor C1 and an emitter of the first triode Q1 are commonly grounded; the collector of the first triode Q1 is connected with the direct-current voltage end 3V3 through a third resistor R3; the collector of the first transistor Q1 is connected to the bluetooth controller U1 as the output of the vehicle speed detection circuit 10.
Referring to fig. 3, when the output terminal of the electromagnetic sensor U2 inputs a pulse square wave signal to the first transistor Q1 through the first resistor R1, it is obvious that the first transistor Q1 can be turned on and off periodically, and the turn-off and turn-on periods are the same as the periods of the pulse square wave signal, and when the collector and emitter of the first transistor Q1 are turned on, it is obvious that the output terminal of the vehicle speed detection circuit 10 is turned on with the ground terminal, and at this time, the vehicle speed detection circuit 10 outputs a low level signal to the bluetooth controller U1; when the collector and the emitter of the first triode Q1 are disconnected, the output terminal of the vehicle speed detection circuit 10 and the dc voltage terminal 3V3 are turned on, and the vehicle speed detection circuit 10 outputs a high level signal to the bluetooth controller U1. Because the electromagnetic sensor U2 outputs the pulse square wave signal with high and low level switching, based on the working principle of the vehicle speed detection circuit 10, it can be determined that the periods of the high and low level signal switched and output by the vehicle speed detection circuit 10 and the square wave pulse signal output by the electromagnetic sensor U2 are the same, and therefore, the bluetooth controller U1 can determine the magnitude of the vehicle speed of the wheel based on the signal period of the high and low level signal output by the vehicle speed detection circuit 10, and further determine whether the wheel is in a rotating state.
It should be noted that, for the vehicle speed detection circuit 10 in which the electromagnetic sensor U2 is a hall sensor, although the output signals of the electromagnetic sensor U2 and the vehicle speed detection circuit 10 are both pulse square wave signals, the peak value of the pulse signal output by the electromagnetic sensor U2 is not certain, and if the pulse signal is directly input to the bluetooth controller U1, the peak value may exceed the receiving range of the bluetooth controller U1. In addition, the electromagnetic sensor U2 is not necessarily a hall sensor outputting a pulse square wave signal, and other electromagnetic sensors U2 with similar functions may also be used, so that the output electrical signal is not necessarily a square wave signal, and the peak value of the signal is rather uncertain. Therefore, in the embodiment, a certain degree of isolation is formed between the signal output by the electromagnetic sensor U2 and the bluetooth controller U1 by using the first triode Q1, so that the safety of the bluetooth controller U1 is ensured on the basis that the bluetooth controller U1 is ensured to be capable of obtaining an electric signal representing the vehicle speed.
In addition, the second resistor R2, the first diode D1, and the first capacitor C1 in fig. 3 are mainly used to ensure stable operation of the entire circuit structure to filter out noise, and detailed description thereof is omitted.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a shock detection circuit according to an embodiment of the present disclosure. In another optional embodiment of the present application, the shock detection circuit 20 may include:
a shock sensor P1 with adjustable sensitivity and a fourth resistor R4; a first end of the shock sensor P1 is connected with a direct-current voltage end 3V3 through a fourth resistor R4; the second end of the shock sensor P1 is grounded; a first terminal of the shock sensor P1 is connected to the Bluetooth controller U1 as an output terminal of the shock detection circuit 20.
The shock sensor P1 and the fourth resistor R4 in fig. 4 are connected in series between the ground and the dc voltage terminal 3V3, and with the change of the shock intensity of the vehicle, the resistance value of the shock sensor P1 changes correspondingly, so that the magnitude of the divided voltage between the fourth resistor R4 and the shock sensor P1 changes, and the node between the fourth resistor R4 and the shock sensor P1 is used as the output terminal of the shock detection circuit 20, and the magnitude of the voltage changes correspondingly, obviously, when the magnitude of the voltage exceeds a certain threshold, it can be determined that the vehicle is shocked severely, and it can be determined that the vehicle is possibly stolen.
Further consider that the alarm device of many cars at present, even if the thunder, the sound of firecrackers are played, and then when sensing slight vibrations, also trigger the warning, cause not good influence for the surrounding environment. For this purpose, a shock sensor P1 with adjustable sensitivity is used in the present application. The knob button can be specially arranged on the operation panel of the two-wheeled electric vehicle for the vibration sensor P1, so that a user can manually adjust the sensitivity of the vibration sensor P1, and the user can select proper sensitivity for the vibration sensor P1 according to the current environment, for example, in a relatively quiet environment, the sensitivity can be increased, and in a noisy environment, the sensitivity can be decreased.
When the bluetooth controller U1 fails to sense and detect the mobile terminal 01 and the signal detected by the vehicle road detection circuit 10 or the vibration detection circuit 20 is greater than the corresponding threshold, the alarm 30 may be set to alarm.
Based on the above discussion, in order to further avoid the user forgetting to pull out the mechanical key, the present application further provides the start detection circuit 40. The input end of the starting detection circuit 40 can be connected with a switch button, when the electric vehicle is used, a user only needs to press the control button to realize one-key starting of the electric vehicle, and when the user needs to stop the electric vehicle, the user can also press the control button to realize the power-off control of the electric vehicle.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a start detection circuit according to an embodiment of the present application. In an alternative embodiment of the present application, the start-up detection circuit 40 may include:
a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, a second diode D2, a third diode D3 and a second capacitor C2;
a first end of the fifth resistor R5 is connected with the switch button; a second end of the fifth resistor R5 is connected to the dc voltage terminal 3V3 through a sixth resistor R6, and a second end of the fifth resistor R5 is connected to a cathode terminal of the second diode D2, a first end of the second capacitor C2, and a first end of the seventh resistor R7; an anode terminal of the second diode D2 and a second terminal of the second capacitor C2 are commonly grounded; a second terminal of the seventh resistor R7 is connected to an anode terminal of the third diode D2; the cathode terminal of the third diode D2 is connected to the bluetooth controller U1 as the output terminal of the start detection circuit 40.
Referring to fig. 5, a first terminal of the fifth resistor R5 is connected to the switch button, and when the switch button is pressed, a low voltage signal is inputted to the first terminal of the fifth resistor R5, and when the switch button is not pressed, the first terminal of the fifth resistor R5 maintains a high voltage signal.
When a low voltage signal is input to the first end of the fifth resistor R5, the low voltage signal is input to the anode end of the third diode D3 through the seventh resistor R7, so that the third diode D3 is in an off state, and at this time, the cathode end of the third diode D3 cannot output a trigger signal to the bluetooth controller U1; when a high voltage signal is input to the first end of the fifth resistor R5, the third diode D3 is turned on, and the cathode of the third diode D3 outputs a trigger signal to the bluetooth controller U1, so that the bluetooth controller U1 sends a motor start control signal to the driving motor system based on the trigger signal.
Of course, it can be understood that, when the driving motor system is in the starting operation state, if the bluetooth controller U1 should receive the trigger signal and send a corresponding control signal to the driving motor system, the driving motor may be electrically stopped from the starting operation state, so as to stop the electric vehicle.
In order to ensure the safety of the electric vehicle, when the driving motor is in a power-off state, if the bluetooth controller U1 does not sense the mobile phone of the user, the bluetooth controller U1 does not send a control signal of the driving motor to the driving motor even if the switch button is pressed for control.
The second diode D2 and the sixth resistor R6 correspond to a filter circuit, and the operation stability of the start detection circuit 40 is maintained by filtering out a noise signal.

As shown in fig. 6, the first terminal of the eighth resistor R8 in the indicator light control circuit 50 may be a PWM signal when receiving the voltage control signal output by the bluetooth controller U1. When the first end of the eighth resistor R8 is a high level signal, that is, a high level signal is output to the base of the second triode Q2, the collector and the emitter of the second triode Q2 are turned on, and a low voltage signal is introduced to the base of the third triode Q3, so that the emitter and the collector of the third triode Q3 are turned off, and power supply to the LED indicator lamp connected to the collector of the third triode Q3 is blocked; when the first end of the eighth resistor R8 is a low level signal, that is, a low level signal is output to the base of the second transistor Q2, the collector and the emitter of the second transistor Q2 are disconnected, and a high voltage signal is connected to the base of the third transistor Q2, so that the emitter and the collector of the third transistor Q2 are connected, and the LED indicator light is supplied with power from the collector of the third transistor Q2.
