Problems solved by technology

In addition, because the operator's main energy is concentrated on the monitoring of the quality of the operation process itself, the safety of the operation process is often ignored, so that the rollover accident rate of agricultural equipment remains high
[0003] The self-propelled spraying machine with high ground clearance has the characteristics of high center of mass, large center of mass change, and complex operating environment. When driving at high speed or tur...

Embodiment 1

[0058] figure 1 It is the flow chart of the spraying machine rollover warning provided in this embodiment, see figure 1 , the sprayer rollover early warning method includes:

[0059] S1: Obtain the operating attitude information of the spraying machine, and calculate the lateral load transfer rate LTR of the spraying machine according to the operating attitude information;

[0060] S2: Correct the obtained lateral load transfer rate LTR according to the amount of chemical liquid in the liquid storage tank of the sprayer to obtain the corrected lateral load transfer rate LTR';

[0061] S3: Determine whether the corrected lateral load transfer rate LTR' is within the preset alarm threshold range, if yes, send an alarm message, otherwise return to step S1.

[0062] It should be noted that: the spraying machine's working attitude information includes the spraying machine's driving speed, lateral acceleration, roll angle, pitch angle, longitudinal acceleration, etc.

Embodiment 2

[0091] image 3 It is a structural schematic diagram of the sprayer rollover warning system provided in this embodiment, see image 3 , the sprayer rollover early warning system A includes an acquisition module A1, a calculation module A2, a correction module A3 and a judgment module A4.

[0092] Wherein, the obtaining module A1 is used to obtain the operation attitude information of the spraying machine;

[0093] Calculation module A2, used to calculate the lateral load transfer rate LTR of the sprayer according to the operation posture information;

[0094] The correction module A3 is used to correct the lateral load transfer rate LTR according to the amount of chemical liquid in the liquid storage tank of the sprayer, so as to obtain the corrected lateral load transfer rate LTR';

[0095] The judging module A4 is used to judge whether the corrected lateral load transfer rate LTR' is within the preset alarm threshold range, if so, send an alarm message, otherwise return to...

Embodiment 3

[0104] Figure 4 It is a flow chart of the spraying machine rollover warning method provided in this embodiment, see Figure 4 , after obtaining the working attitude of the sprayer, judge its working status type, according to 6 different working status types (high-speed steering, acceleration and deceleration uphill and downhill, uniform speed uphill and downhill, ramp camber, ramp inclination and ramp constant speed), Calculate the current lateral load mobility LTR of the sprayer, and correct the LTR according to the liquid level information of the liquid storage tank to obtain the corrected lateral load mobility LTR'. Determine whether the LTR' is within the preset threshold range, if so, send an alarm message, indicating that the sprayer is currently in danger of tipping over, if not, continue to collect operating attitude information.

[0105] Figure 5 It is the flow chart for judging the type of spraying machine operation status provided by this embodiment, see for exa...

Abstract

The invention discloses a side-tilting prewarning method and system for a chemical spraying machine. The method comprises steps as follows: S1: operation attitude information of the chemical spraying machine is acquired, and a transverse LTR (load transfer rate) of the chemical spraying machine is calculated according to the operation attitude information; S2: the transverse LTR is corrected according to the quantity of liquid chemicals in a liquid storage tank of the chemical spraying machine, and a corrected transverse LTR' is obtained; S3, whether the corrected transverse LTR' is in a preset alarm threshold value range is judged, if the answer is positive, warning information is sent out, and otherwise, the step S1 is performed again. According to the side-tilting prewarning method and system for the chemical spraying machine, the real-time motion state of the chemical spraying machine is acquired, the operation state type of the chemical spraying machine is judged, a side-tilting prewarning value is calculated and then corrected, and the accuracy of the prewarning value is improved; the corrected prewarning value is compared with a preset prewarning threshold value range, whether a sound-light alarm is sent to a driver through a prewarning module is judged, and the purpose of preventing a side-tilting accident is achieved.

Description

technical field [0001] The invention belongs to the technical field of safety, and in particular relates to a method and a system for early warning of side tilting of a spraying machine. Background technique [0002] The hazards of rollover accidents of self-propelled agricultural equipment have attracted enough attention from the society. At present, the anti-rollover protection system commonly used abroad can only play a role in passive protection of equipment, and cannot fundamentally prevent accidents from happening. According to statistics, about 30,000 people around the world are injured or even die every year due to agricultural equipment rollover accidents. Among the agricultural equipment that had accidents, self-propelled agricultural equipment was the main one, and the main reasons for its rollover included making an emergency turn on the ground with a large slope, hitting ground obstacles, or pulling inappropriate work tools, etc. In addition, because the operat...
