AI Technical Summary

Problems solved by technology

However, connecting to AC power will affect the mobility of the lawn mower, and it can only mow small areas, such as domestic lawns
There are also problems with the way of setting up the lithium battery. Due to the limited capacity of the lithium battery, the lawn mower can only complete the mowing task for a short time, and cannot work continuously for a long time.
In addition, the life of lithium batteries is limited, and the lithium batteries that need to be disposed of will cause serious secondary pollution to the environment (there is also some pollution in the preparation of lithium batteries)
[0005] Moreover, a large part of the electric energy charged by lithium batteries is obtained through non-renewable resources such as coal and oil, and the process of power generation will also pollute the environment; electric energy will be damaged during transmission, and the charging process will also make power loss
In addition, the existing lawn mowers need to be controlled manually, which is tiring and the work efficiency is not high

Embodiment 1

[0079] See Figure 1 to Figure 5 , The present invention discloses an automatic lawn mower, including a lawn mower body, a delineation mechanism 20 for enclosing the area to be cut, the lawn mower body includes: a first motor 11, a cutter head 13, and a blade 14. , Hydrogen generator 30, raw material storage container 40, traveling wheel 15, second motor 12, housing 10 and main control circuit.

[0080] The outer side of the housing 10 is provided with a sensor 16 (for example, it may include an external line sensor, an ultrasonic sensor, and a pressure sensor), and the external line sensor, an ultrasonic sensor, and a pressure sensor are connected to the main control circuit.

[0081] When the lawn mower body is close to the delimiting mechanism 20, the pressure sensor is in contact with the delimiting mechanism 20, and when pressure is sensed, it is considered to have contacted the delimiting mechanism 20, and it can be turned immediately; or through an outside sensor or / and ultra...

Embodiment 2

[0091] The difference between this embodiment and the first embodiment is that in this embodiment, a hardness sensor is provided on the periphery of the first housing, and the hardness sensor is connected to the main control circuit. When the hardness sensor senses an object with a hardness greater than the set value, the main control circuit can control the walking wheel to stop walking.

Embodiment 3

[0093] The difference between this embodiment and the first embodiment is that in this embodiment, the control system of the automatic lawn mower includes a system power management circuit, a main control circuit, and a cutter control circuit.

[0094] See Figure 6 to Figure 9 , Image 6 For the power management circuit of the system, the voltage stabilized power supply is provided, and two voltages are provided for the system. The lawn mower is internally powered by a 24V battery (which can be powered by a battery or directly by a hydrogen fuel cell). The circuit can convert a DC 24V voltage to a 5V voltage and can output a 3.3V voltage.

[0095] Control circuit such as Figure 7 , Figure 8 Shown, use STM32F103ZE6 as the main control chip. Choose the ultrasonic module URM37V3.2 as the obstacle avoidance sensor, and use the GP2D02 as the infrared distance sensor. Design the level conversion circuit in the interface of STM32F103ZET6 and URM37V3.2, choose MAX232 chip to realize T...

Abstract

The invention discloses an automatic mower and a control system thereof. The mower comprises a mower body and a delineation mechanism used for delineating an area in which grass is to be cut. The mower body comprises a first electric motor, a cutter, a blade, a hydrogen water machine, a raw material storage container, a traveling wheel, a second electric motor, a shell and a main control circuit;a distance sensor and / or a pressure sensor is arranged on the outer side of the shell, and the distance sensor and / or the pressure sensor is connected with the main control circuit; the first electricmotor, the cutter and the second electric motor are arranged in the shell; the hydrogen water machine is arranged in the shell; and the hydrogen water machine comprises a methanol water reforming hydrogen production device, a hydrogen fuel cell, an air pump and a liquid pump. According to the automatic mower and the control system thereof provided by the invention, the mower can be controlled towork automatically, the labor cost is reduced, and meanwhile the equipment noise can be reduced, and the continuous work of the machine also can be ensured without depending on nonrenewable resources.In addition, the cost needed by hydrogen production power generation by using the methanol is lower and the user cost can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of lawn mowers, and relates to a lawn mower, in particular to an automatic lawn mower; meanwhile, the invention also relates to a control system of the automatic lawn mower. Background technique [0002] Lawn mowers are also called lawn mowers, lawn mowers, lawn trimmers, etc. The lawn mower is a mechanical tool used for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutter head is installed on the traveling wheel, the cutter head is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, saving the weeding worker's working time and reducing a lot of human resources. [0003] Normal lawn mowers use gasoline to drive the engine to work, which makes a lot of noise, which affects people’s work and ...
