Infrared seeding monitoring device

Abstract

The invention relates to an infrared seeding monitoring device which comprises a singlechip, an infrared emission circuit, an infrared detection circuit, a buzzer voice alarm circuit and an LCD circuit, wherein a control unit of the detection device adopts a 8-bit singlechip; a power supply circuit comprises a voltage-stabilizing module and provides a stable +5V voltage for the system through a capacitance filter; the infrared emission circuit adopts an infrared pipe and is demodulated into a 38kHz infrared carrier signal by using a timer of the singlechip, and the 38kHz infrared carrier signal is output by a P2.7 port, is amplified by an audion, and is transmitted by an infrared transmission pipe; and an infrared receiving circuit has a core of an infrared receiving module which is a receiver integrating the receiving and the amplifying of an infrared raw signal, wherein the center receiving frequency of the receiver is 38kHz, the output of the receiver is TTL level, the output of the receiver at ordinary times is high level, and when a code signal is received, the output is low level. The invention can ensure that the signal is accurately controlled by the singlechip, and has simple and stable mechanical structure and reasonable circuit design.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a real-time monitoring device which uses an infrared tube to accurately measure the seeding amount and feeds back the information to a seeding mechanism to realize seeding. Background technique [0002] Sowing is an extremely important link in the agricultural production process. With the development of sowing technology, sowing methods and sowing tools are constantly changing. In recent years, with the development of precision agriculture, precision seeding technology has been greatly developed, and the confidential seeder has become the development direction of modern seeding technology. In the process of seeding operation, due to its fully enclosed feature, the operator cannot directly monitor the operation quality. Therefore, when process failures such as emptying of the seed box, blockage of the seed delivery pipe, failure of the seed meter or blockage of the opener occur, , will caus...

AI Technical Summary

Problems solved by technology

Regardless of whether photoelectric or piezoelectric acoustic sensors are used, during the sowing process, multiple seeds may pass through the sensor at the same time or with a very short interval, which may lead to false detection and affect the accuracy of detection.

Second, automatic compensation cannot be realized

When the lower seed tube cannot sow normally, the monitoring system will send out an alarm. Due to the certain speed of the car itself, it will cause certain missed seeding and replaying before the operator picks up the car for inspection.
