Problems solved by technology

[0003] Compared with foreign countries, most of the domestic research on precise sowing control technology involves the fields of monitoring missed sowing, replaying and fault alarms in the sowing process, and most of these control systems have certain deficiencies: 1) The phenomenon of ground wheel slipping is still inevitable, resulting in the discharge of 2) It is troublesome to adjust the seeding rate, and the adjustment accuracy is not enough, it is necessary to stop the machine and manually adjust the sprocket

Embodiment Construction

[0020] Such as figure 1 As shown, the wheat two-line precision sowing intelligent control system is composed of two parts: the host system and the slave system. Sowing, monitoring of sowing status and faults, etc.; two control units realize wireless transmission of relevant data through Bluetooth. The intelligent control precision seeder uses independent buttons to set the seeding parameters (including seed spacing and seeding amount); the rotary encoder is used to measure the forward speed of the seeder. After the speed measurement signal is sent to the host through the conditioning circuit and received and processed, the host then sends the parameter information such as the current vehicle speed and the set broadcast volume (grain distance) to the slave through the Bluetooth wireless transceiver module, and the slave performs comprehensive calculations to obtain At this time, the proper rotational speed of the stepping motor is used to control the rotational speed of the se...

Abstract

An intelligent control system for two-line precision sowing of wheat In order to avoid the adverse effect of ground wheel slipping on the uniformity of sowing and ensure better sowing quality, an automatic control system for seeders was invented, which uses stepping motors to drive seed metering devices . The system takes the AT89C55 single-chip microcomputer as the control core, uses the rotary encoder to collect the forward speed information of the seeder in real time, and the microprocessor (CPU) judges the speed, and adjusts the step in real time in combination with the setting of the seed distance (or sowing amount) The rotation speed of the motor is used to drive the seed meter to sow on demand. In addition, the system can also realize auxiliary functions such as liquid crystal display and sound and light alarm. The test results show that the working performance of the system is stable and reliable, and can meet the requirements set during sowing.

Description

technical field [0001] The invention relates to an intelligent control system, in particular to an intelligent control system for two-line precision sowing of wheat. Background technique [0002] In recent years, precision seeding has become the main development direction of modern seeding technology. With the continuous development of electronic information technology, automatic control technology has been widely used in precision seeding industry. The research and application of precision seeding in foreign countries is relatively early. In the 1980s, a radar-based speedometer for measuring walking speed, sowing density and grain leakage came out; in 1995, Polish scientists developed a set of equipment UKS-1 The electronic control system of the seed meter, the system can be programmed according to the working width, the radius of the ground wheel and different models, which improves the operating conditions and is easy to operate and improve work efficiency; in 1996, Dicke...
