Since electric battery charging stations are not widely available, it is necessary to provide accurate information on the remaining usable time of electric batteries. However, unlike automobiles in which there is no significant difference in load according to weight even when a person is on board, agricultural machinery has a large load depending on a work device connected to a power take-off (PTO). Therefore, the remaining usable time of the battery cannot be measured based on the basic weight of the agricultural machine, and the remaining usable time must be measured according to the work device connected to the PTO.

Therefore, there is a need for a method and apparatus for providing information on the remaining usable time of a battery according to a work device connected to a power take-off (PTO) of an agricultural machine driven by an electric battery.

1 illustrates an example of autonomous driving of an agricultural machine according to various embodiments of the present disclosure.

Agricultural machinery is treated as a very important factor to reduce high labor burden and production cost in response to labor shortage due to the decrease and aging of rural labor population. Agricultural machinery is for carrying out various types of work necessary for farming, and is capable of various types of work such as plowing, rotary, pest control, and transplanting. A walking type work machine operated by a worker while walking with the agricultural machine and a worker equipped on the agricultural machine It is classified as a riding machine that operates agricultural machinery by riding in the driver's seat.

Various embodiments of the present invention disclose a device applicable to agricultural machines classified as riding machines such as tractors.

Driving of agricultural machines on farmland such as rice fields or fields involves work.

The user of the agricultural machine can directly perform manual driving control. The user of the agricultural machine can directly control the forward or backward movement of the machine by manipulating the shuttle lever of the machine, and can control the path of the machine by manipulating the steering wheel.

A drive control device for controlling forward or backward driving for autonomous driving of the agricultural machine may be installed in the agricultural machine. In this case, the agricultural machine may move according to a set path, and may move forward or backward according to a bar set by a user of the agricultural machine. Autonomous driving can be controlled and set through information exchange between a drive control device installed in an agricultural machine and a user device. A user may generate autonomous driving-related setting information and transmit it to a driving control device using a user device, such as a smartphone or a computer, which is a terminal capable of calculating information and transmitting and receiving information. The driving control device includes a transceiver and a processor, and is electrically connected to the driving unit of the agricultural machine to control the driving unit. The driving control device may receive autonomous driving-related setting information from a user device, and may control forward or backward movement of a driving unit of an agricultural machine according to the autonomous driving-related setting information.

In this case, the steering control device may be configured to control the steering wheel so that the agricultural machine moves along a set path according to the autonomous driving-related setting information received from the user device. The steering control device may be configured to be mechanically connected to the steering wheel and rotate the steering wheel according to a set path. The steering control device may receive autonomous driving-related setting information from a user device including a transceiver. The steering control device may include a processor and control rotation of the steering wheel according to setting information related to autonomous driving.

2 illustrates an example of a power take off (PTO) of an agricultural machine according to various embodiments of the present disclosure.

A power take-off (PTO) is a device used when a driving device, for example, an engine or a motor's rotational power, is used for a purpose other than the original purpose of the device. Air compressors, generators, and many other power devices can be connected to the PTO. The power of the ladder car is also supplied through the PTO. It is usually used in automobiles (agricultural trucks, etc.) or agricultural machinery (cultivators, tractors, etc.), and is also installed on ships, and in this case, it connects fire suppression devices or generators.

The PTO increases efficiency by allowing the drive unit in one unit to be used for a wide variety of purposes. For example, in the case of an agricultural pesticide sprayer, if there is no PTO, a model with an engine or motor must be obtained, which is heavy and expensive and maintenance is cumbersome. . In addition to agricultural use, the PTO is useful when there are cars (trucks) and multiple power units are needed at construction sites.

The PTO makes the drive unit very efficient for a variety of uses, but it also presents the risk of an accident. In particular, when connecting other power devices such as a threshing machine to the outside for agricultural use, there are many cases where a person's body or clothes are caught in the power shaft, resulting in safety accidents. PTO has a high possibility of fracture or death in the event of a safety accident due to its enormous torque. For example, in the United States, 6% of tractor deaths are serious enough to be attributed to PTO.
