摘  要:
精量播种机的监测系统是现代精播机的一个重要组成部分,其性能优劣将影响精量播种的质量,精播机对不同性能有不同的要求,而且其参数覆盖面广。为了实现对精量播种机排种性能的自动监测,以及提高农作物的播种质量,在借鉴国内外研究的基础上,设计了一种精量播种机自动监测系统。系统选用激光栅格光电传感器采集信号,AT89C51单片机作为控制器,采用8259A中断控制器扩展中断端口、8155芯片扩展I/O端口,由显示装置显示排种量,并通过指示灯和蜂鸣器对故障进行报警,以及时提醒驾驶员停车检查。该系统具有结构简单、成本低廉、可靠性高和便于扩展等特点,对发展高效农业具有重要意义。

摘  要:
Seeding monitoring system is an important component of present precision drill and its function directly affects the quality of precision seeding.There are different demands to the different performances,and its parameters are widely covered with.In order to carry out the automatic monitoring system of precision drill,increase the seeding quality.Based on analyzing studies in domestic and overseas,the monitoring system was designed.The system use grid laser Photosensor to collect the signal,employ the AT89C51 single chip as controller and use the 8259A interrupt controller to expand the interrupt port,use 8155 chip to expand the I/O port.Displaying the quantity of seeding by display unit and use the pilot lamp and the buzzer to alert troubles and warn the driver stop and check them in time.The system has features such as simple structure,low cost,high reliability and easy to install.So it is very significant to the development of the high-efficiency agriculture.
