when the vehicle is in a non-lifting state, if the tire pressure difference is larger than or equal to a first maximum tire pressure difference between the two coaxial sides, sending an alarm signal;
and when the vehicle is in a lifting state, if the tire pressure difference is greater than or equal to the second maximum tire pressure difference between the two coaxial sides, the height of the carriage is adjusted.
2. The method for preventing the dump truck from rolling according to claim 1, wherein the adjusting the height of the car comprises:
and controlling the lifting controller to stop the lifting action and reduce the height of the carriage to enable the height of the carriage to be smaller than or equal to the preset safety height.
3. The method for preventing a roll of a dump truck according to claim 1, wherein the method further comprises:
acquiring a vehicle lifting signal;
and judging whether the vehicle is in a lifting state or not according to the lifting signal.
4. A system for preventing a roll of a dump truck, comprising:
the first acquisition module is used for acquiring tire pressure values on two coaxial sides;
the calculation module is used for calculating the tire pressure difference between two coaxial sides according to the tire pressure value;
the control module is used for sending an alarm signal if the tire pressure difference is larger than or equal to a first maximum tire pressure difference between two coaxial sides when the vehicle is in a non-lifting state; and when the vehicle is in a lifting state, if the tire pressure difference is greater than or equal to the second maximum tire pressure difference between the two coaxial sides, the height of the carriage is adjusted.
5. The system of claim 4, wherein the control module is specifically configured to:
and controlling the lifting controller to stop the lifting action and reduce the height of the carriage to enable the height of the carriage to be smaller than or equal to the preset safety height.
6. The system for preventing a roll of a dump truck of claim 4, wherein the system further comprises:
the second acquisition module is used for acquiring a vehicle lifting signal;
and the judging module is used for judging whether the vehicle is in a lifting state according to the lifting signal.
7. The system of claim 4, further comprising a switch module for: and when the vehicle is in a maintenance state, the control module is in a dormant state or a closed state.
8. A vehicle, characterized by comprising: the dump truck roll prevention system according to any one of claims 4 to 7.
9. A dump truck roll prevention apparatus, comprising: a memory and a processor, the memory having stored therein at least one instruction, the at least one instruction being loaded and executed by the processor to implement the method of preventing a roll of a dump truck according to any one of claims 1 to 3.
10. A computer-readable storage medium characterized by: the computer storage medium stores computer instructions that, when executed by a computer, cause the computer to perform the method of preventing a roll of a dump truck according to any one of claims 1 to 3.
