Description

Technical Field

[0001] The invention belongs to the technical field of sanitation vehicles, and particularly relates to a weighing method for sanitation vehicles. Background Art

[0002] When recycling kitchen waste and other garbage, charges are based on the weight of the garbage. The corresponding sanitation vehicle needs to be equipped with a garbage weighing system, which has the function of weighing the garbage each time it is loaded and accumulating the garbage weight. The current market mostly uses the method of adding an additional weighing system to meet the above requirements, which adds an additional weighing system and corresponding costs. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a weighing method for a sanitation vehicle, which is used to realize the function of weighing loaded garbage at zero cost.

[0004] The specific plan is as follows: A sanitation vehicle weighing method, characterized in that it comprises the following steps: S1): The sanitation vehicle adopts a motor-driven feeding system. The corresponding relationship between the motor current and weight is calibrated based on the whole vehicle or the motor-driven feeding system, and a calibration database is formed; S2): When the sanitation vehicle feeding system starts working, the vehicle controller records the initial weight value of the garbage in the sanitation vehicle; S3): The vehicle performs the loading action, and the motor controller detects the current value of the motor when driving the loading. According to the detected current value of the motor, the weight value corresponding to this loading action is searched from the calibration database, and the weight value found is used as the weight increase; S4): the motor controller transmits the acquired weight increase to the vehicle controller, and the vehicle controller accumulates the weight increase to obtain a cumulative value of the weight increase; S5): The vehicle controller determines whether the loading action is completed. If not, repeat steps S3) to S4). If it is completed, the vehicle controller adds the accumulated value of the weight increase to the initial weight value as the final weight value.

[0005] The method for calibrating the correspondence between motor current and weight based on the whole vehicle is that the whole vehicle controller executes the loading action, and the motor drives the loading system to start loading objects of different weights and detect the corresponding motor current value.

[0006] The method for calibrating the corresponding relationship between motor current and weight based on the motor-driven feeding system is as follows: installing the motor-driven feeding system on a test bench, starting the motor-driven feeding system, loading the motor-driven feeding system with objects of different weights and detecting the corresponding motor current values.

[0007] The initial weight value of the garbage in the sanitation vehicle is zero or the final weight of the last weighing when the garbage is not dumped.

[0008] The power source of the feeding system is a motor, and the power transmission is a hydraulic mechanism or a rack and pinion mechanism.

[0009] The invention discloses a weighing method for a sanitation vehicle. The sanitation vehicle uses a motor to drive a feeding system, calibrates the correspondence between the weight of the fed garbage and the motor current, forms a calibration database, detects the motor current value during each feeding action, searches for the corresponding weight according to the calibration database, accumulates the weight corresponding to each feeding action, and realizes an automatic weighing function without adding an additional system and corresponding costs.
