Definitions
- the present invention relates to the field of smart cars, and more particularly to a smart car balance detecting device.
- the invention provides a smart car balance detecting device, which detects the balance of the automobile, and when the car loses balance in the following, that is, an alarm, the car is safely driven.
- the present invention adopts the following technical solutions:
- a smart car balance detecting device comprising a direction sensor, an acceleration sensor, a controller and four weighing sensors respectively disposed on four wheels, wherein the load cell, the direction sensor and the acceleration sensor are connected to the controller, An alarm device is also connected to the controller.
- the load cell is a digital load cell.
- the direction sensor is disposed on a turntable of a car.
- a speed sensor is further included, and the speed sensor is coupled to the controller.
- the alarm device is a buzzer.
- the controller is an MSP 430.
- the invention utilizes a load cell to detect the balance of the automobile, and when the car loses balance in the following, that is, an alarm, the vehicle is safely driven.
- Figure 1 is a schematic block diagram of the present invention.
- the smart car balance detecting device shown in FIG. 1 comprises a direction sensor, an acceleration sensor, a controller and four weighing sensors respectively arranged on four wheels, and the load cell, the direction sensor and the acceleration sensor are connected in the control.
- an alarm device is also connected to the controller.
- the load cell is mounted on the four wheels of the car, and the load-bearing conditions of the four wheels are detected.
- the direction sensor and the acceleration sensor respectively detect the direction and acceleration of the car.
- the controller determines whether the car is in an unbalanced state according to the data detected by the direction sensor and the acceleration sensor. State, to control the alarm device to start the alarm.
- the direction sensor detects that the direction of travel of the car is directly in front of the car. At this time, if the load-bearing conditions of the four wheels are different, the controller determines that the car is unbalanced. Then, the control alarm device starts to alarm.
- the direction sensor detects that the direction of travel of the car is not in line with the direction of the vehicle body.
- the controller detects the direction of the car and the state of the car detected by the acceleration sensor according to the direction sensor, that is, The angle of the offset and the magnitude of the acceleration determine the balance state of the car. If the car is in a normal turning or lane change state, the car runs normally. If it is determined that the car is in an unbalanced state, the control alarm device starts to alert, reminding people to pay attention. Or replace it with human driving to stop the car to check the condition of the vehicle to ensure safe driving.
- the load cell is a digital load cell.
- the digital load cell detects the bearing condition of the wheel.
- the data transmission distance is long, the anti-interference ability is strong, and there is a unique mark.
- the state of each sensor can be detected separately, which is convenient for fault diagnosis.
- the structure of the digital load cell detection is digital, and its structure is directly transmitted to the controller, which facilitates the processing of the controller and simplifies the processing circuit.
- the direction sensor is disposed on a turntable of the automobile.
- the direction sensor is used to detect the direction of travel of the car. Since the turntable controls the direction of travel of the car, the direction sensor is placed on the turntable of the car to facilitate direct detection of the direction of travel of the car.
- the speed sensor is used to detect the traveling speed of the automobile, which can enhance the detection accuracy of the balance of the present invention.
- the speed sensor is used to detect the speed of the car. When the vehicle is in a low speed state, such as reversing or parking, the controller misjudges the balance state.
- the alarm device is a buzzer. Remind the driver with a buzzer to reach the reminder The purpose of the driver's attention.
- the controller is MSP430. Using the MSP430 as a controller, its sensitivity is high, which improves the reliability of the entire device.
