Detailed Description
The utility model is further described below with reference to the drawings and examples.
As shown in fig. 1 and fig. 2, a system for preventing side turning of a farm management vehicle comprises a carriage 1, wherein weight sensors 2 are arranged in the carriage, in this embodiment, the number of the weight sensors 2 is 4, and the weight sensors are respectively arranged at four corners of the carriage 1 and are used for detecting the weight born by the four corner positions of the carriage.
The two sides of the carriage 1 are respectively provided with a first angle sensor 21 and a second angle sensor 22, which are specifically arranged below the two sides of the carriage 1 and can be oppositely arranged left and right. The first angle sensor 21 and the second angle sensor 22 are used to detect the corresponding side inclination angle θ of the vehicle compartment 1. When the vehicle runs on the flat ground 10, the first angle sensor 21 and the second angle sensor 22 can detect that the inclination angle theta of the two sides of the carriage 1 is 0 degrees, and when the carriage is prone to rollover and incline, the first angle sensor 21 and the second angle sensor 22 can detect that the specific overturning angle of the carriage is the inclination angle theta.
The weight sensor 2, the first angle sensor 21 and the second angle sensor 22 are connected with the micro-control unit 3, and a storage module 31 is arranged in the micro-control unit 3 and is used for storing the weight threshold value, the weight difference threshold value, the first angle threshold value and the second angle threshold value. The weight sensor 2, the first angle sensor 21 and the second angle sensor 22 transmit the detected data to the micro control unit 3, the micro control unit 3 compares the received data with the weight threshold value, the weight difference threshold value and the angle threshold value stored in the storage module 31, when the detected data of the four weight sensors exceeds the weight threshold value or the front-rear side or the left-right side stress difference exceeds the weight difference threshold value or the result of the first angle threshold value and the second angle threshold value exceeds the angle threshold value, the micro control unit 3 judges that the vehicle has a rollover risk, and the micro control unit 3 sends a signal to the ECU control unit 5. The weight threshold and the weight difference threshold are determined according to the bearing of the garden management vehicle, and in the embodiment, the first angle threshold and the second angle threshold are set to 15-22 degrees.
The micro-control unit 3 is connected with the ECU control unit 5 through the receiver 4, and the ECU control unit 5 is connected with the alarm 6. The micro control unit 3 sends a control signal of the previous comparison result to the ECU control unit 5 through the receiver 4, and the ECU control unit 5 controls the alarm 6 to start.
The micro control unit 3 is also connected with a vehicle speed sensor 7 and a GPS locator 8, and the storage module 31 also stores a vehicle speed threshold value and a mountain road map. So configured, the micro-control unit 3 may signal the ECU control unit 5 to activate the associated alarm 6 to alert the driver when the vehicle speed exceeds a vehicle speed threshold or the vehicle enters a mountain area.
In the present embodiment, the ECU control unit 5 is also connected to a motor drive control unit 9. The ECU control unit 5 may instruct the motor drive control unit 9 to control the motor to slow down or stop advancing when there is a risk of rollover.

Meanwhile, the first angle sensor 21 and the second angle sensor 22 detect the inclination angle of the vehicle, when the inclination angle theta is 0-15 degrees, the micro control unit 3 does not send out a signal, the alarm 6 does not send out an alarm, when the inclination angle theta is 15-22 degrees, the micro control unit 3 sends a control signal to the ECU control unit 5, the ECU control unit 5 controls the alarm 6 to send out an alarm to warn a driver, and the rollover angle is displayed on the angle display; when the inclination angle theta exceeds 22 degrees, the alarm 6 continuously sends out a warning, the ECU control unit 5 gives an instruction to the motor drive control unit 9, and the motor rotation speed is adjusted to control the vehicle speed to stop or slow down the vehicle. Meanwhile, since the micro control unit 3 is also connected with the vehicle speed sensor 7 and the GPS locator 8, the storage module 31 also stores a vehicle speed threshold value and a mountain road map. Therefore, when the vehicle speed exceeds the vehicle speed threshold or the vehicle enters the mountain area, the micro-control unit 3 sends a signal to the ECU control unit 5 to activate the relevant alarm 6, thereby giving a warning to the driver. Beyond the higher permission, the alarm 6 continuously sends out a warning, and the ECU control unit 5 controls the motor to be decelerated or stopped through the motor drive control unit 9, so that the life and property safety of drivers and passengers is ensured.
