[0022] The utility model is further described in detail below:

[0023] The utility model provides a motorcycle parking prompt warning system, comprising a parking detection unit, a control unit and a prompt warning unit;

[0024] The parking detection unit is used to detect the parking state of the motorcycle and output the parking state of the motorcycle to the control unit;

[0025] The control unit, whose input end is connected to the parking detection unit, is used to receive the parking status information output by the parking detection unit and output a parking prompt warning instruction according to the parking status information;

[0026] The input end of the prompt warning unit is connected to the output end of the control unit, and is used to receive the prompt warning instruction output by the control unit and execute the prompt warning. Through the above structure, the parking state of the motorcycle can be detected, and the user's leaving state can be accurately detected after the motorcycle stops, and corresponding prompt warnings can be issued according to the detection results, thereby effectively preventing the user from losing mobile phones and other personal belongings and avoiding economic losses to the user.

[0027] In this embodiment, the parking detection unit includes a current sensor, which is used to detect the current signal of the circuit where the motorcycle key switch is located and output it to the control unit. When the key switch is closed, the circuit has current, which indicates that the motorcycle is not stopped. When the key switch is disconnected, the current sensor has no output, which indicates that the motorcycle is stopped. The current sensor adopts an existing Hall sensor.

[0028] In this embodiment, the parking detection unit includes an engine speed sensor, and the output end of the engine speed sensor is connected to the control unit. When the engine speed sensor outputs that the engine speed is 0, it can be determined that the current state is parking, thereby providing a basis for subsequent judgment.

[0029] In this embodiment, the parking detection unit further includes a pressure sensor, which is arranged under the seat of the motorcycle and is used to sense whether the driver has gotten off the motorcycle. The output end of the pressure sensor is connected to the control unit. When the pressure sensor outputs a right signal, it indicates that the driver is on the motorcycle. If there is no signal output, it indicates that the current driver has gotten off the motorcycle and intends to leave. At this time, the control unit controls the prompt warning unit to work according to the signal and gives a voice prompt.

[0030] In this embodiment, the parking detection unit also includes a human body distance detector, the output end of which is connected to the control unit, wherein the human body distance detector adopts an existing infrared human body detector to sense the distance between the user and the current motorcycle. When the distance exceeds a set value (generally not more than 2 meters), the control unit controls the voice prompter to increase the warning volume.

[0031] In this embodiment, a delayed power-off control circuit is also included. The delayed power-off control circuit is used to start working when the engine speed output by the engine speed sensor is 0, and delay the set time to disconnect the power supply circuit of the parking detection unit, the control unit and the prompt warning unit. After parking, the user will turn off the engine, so that the engine speed is 0. However, the engine is turned off, which causes the power supply of the entire motorcycle system to be turned off, so the control unit, the detection unit and the prompt warning unit cannot work. Therefore, the above situation can be prevented by the above-mentioned delayed power-off control circuit. Specifically: Figure 2 As shown: the delayed power-off control circuit includes a PMOS transistor Q1, a transistor Q2, a transistor Q3, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5 and a capacitor C1, wherein the transistor Q2 is a P-type transistor;

[0032] The source of the PMOS tube Q1 is connected to the vehicle power supply, the drain of the PMOS tube Q1 is used as the output end to supply power to the load, the emitter of the transistor Q2 is connected to the source of the PMOS tube Q1, the collector of the transistor Q2 is connected to the gate of the PMOS tube Q1 through the resistor R6, the gate of the PMOS tube Q1 is connected to the collector of the transistor Q3 through the resistor R4, the emitter of the transistor Q3 is grounded, the base of the transistor Q3 is connected to the collector of the transistor Q4 through the resistor R3, the base of the transistor Q4 is connected to the output end of the key switch SK through the resistor R5, and the base of the transistor Q2 is connected to the output end of the key switch SK through the resistor R1; one end of the resistor R2 is connected to the output end of the key switch SK of the motorcycle, the other end of the resistor R2 is grounded through the capacitor C1, and the common connection point of the resistor R2 and the capacitor C1 is connected to the emitter of the transistor Q4; wherein the capacitor C1 is used as a delay capacitor;

[0033] In the above circuit, when the key switch SK is turned off, although the transistor Q2 is turned on, the transistor Q3 is turned off, so that the PMOS tube Q1 is turned off, that is, the motorcycle is in a power-off state. At this time, the vehicle power supply (that is, the vehicle battery is not powered). When the key is inserted, the key switch is in the ON position, indicating that the current motorcycle is in a power-on state. At this time, the load of the motorcycle is powered on when SK is in the ON position. At the same time, the capacitor C1 is charged through the resistor R2. Since the value of the resistor R5 is less than the value of the resistor R2, the transistor Q4 is turned off, the transistor Q3 remains turned off, and at the same time, the transistor Q2 remains turned on, but the PMOS tube Q1 remains When the motorcycle stops and the power is cut off again, the transistor Q2 is still turned on at this time. However, due to the reverse bias between the emitter and the base of Q4, the transistor Q4 is turned on, and then the transistor Q3 is turned on, so that the PMOS tube Q1 is turned on, so that the detection unit, the control unit and the prompt unit can still work for a certain time after the motorcycle stops (the time is determined by C1, and different delay times are achieved by C1 with different capacitance values). When C1 is discharged (not necessarily completely discharged, until the voltage provided by C1 can no longer turn on Q3), the transistor Q3 is restored to be cut off, and the PMOS tube Q1 is cut off, so that the power supply of the motorcycle completely stops.

[0034] In this embodiment, the control unit is a smart meter or a vehicle-mounted controller, which can save costs and is convenient to use.

[0035] In this embodiment, the prompt warning unit is a voice prompter, and the control input end of the voice prompter is connected to the control unit, wherein the prompt warning unit adopts an existing speaker or sound that can adjust the volume according to instructions.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
