Air-suction no-tillage corn planter intelligent monitoring device based on embedded computer

Abstract

The invention discloses an air-suction no-tillage corn planter intelligent monitoring device, and belongs to the field of agricultural machinery intelligent monitoring. According to the device, the sensor technology, the wireless communication technology and the embedded technology are combined, and a PXA270+CPLD+IPC system structure is adopted; the software and hardware resources of the whole device are managed through a wireless communication protocol and C++ language programming and processing threads under the Windows CE system environment so that the functions of data acquisition, metering, alarm, control and communication are integrated; data acquisition and control are respectively controlled by a processor so that each monitoring point is enabled to be real-time, accurate and efficient, adding of the monitoring point is easy, fault maintenance is convenient, space occupation is small, the device can be installed in a homemade closed control box arranged at the side surface of an engine, and thus the influence of field moisture and dust and other environmental factors can be avoided; and operation is reliable so that the problems that polling detection has no alarm or seed manure tubes perform false alarm when the engine starts to operate do not occur. The actual requirements of field seed manure operation monitoring of the air-suction no-tillage corn planter in the northern cold areas can be completely met.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitoring of agricultural machinery, and in particular relates to an intelligent monitoring device for an air-suction no-tillage corn planter. Background technique [0002] my country's total corn production ranks second in the world, and the continuous field operation of corn sowing has a large area, which is especially suitable for high-horsepower corn precision sowing machinery, and has become the key to increasing production and income. At present, most of the corn precision seeders used in China are mechanical and pneumatic, and the sowing operation process is completely closed. Once the phenomenon of "broken strips" and missed sowing or missed application occurs during the sowing process, it cannot be directly continued by human audiovisual alone. Monitoring, especially for the no-tillage corn planter used for sowing and fertilizing operations, due to the straw cover on the working surf...

Problems solved by technology

Through field use, it is found that there are many power supply wirings for 15-chip single-chip microcomputers, coupled with wired communication, the wiring is complicated, the placement position is not easy to determine, and there are many power supply wirings, especially when the system is tested, the system works by polling. Information, program running time Delay program is used in many places, and the delay time determines whether the information of each monitoring point can be collected

For example, the same alarm program normally alarms at the 15th monitoring point, but does not alarm at the first monitoring point, with poor reliability, slow response speed, poor real-time performance, and prone to system failures, which affect real-time monitoring performance

In addition, in order to improve the operation quality of large-scale corn planters, according to the actual field sowing operations, the monitoring of tillage depth, sowing depth and corn sowing mechanical performance parameters should be increased.
