Embodiment 2  application Embodiment 1

[0066] Refer below Figure 6 Introduce the application example 1 of the present invention - the application of visual navigation of agricultural vehicles (001):

[0067] During the field work of agricultural vehicles, there are always working areas and non-working areas. Use this measurement and control system and the industrial camera configured to detect the boundary line of the working area and the non-working area in real time, and then obtain the heading deviation and navigation position deviation. Through the constructed navigation control The system realizes the automatic steering of the steering wheel, and finally achieves the purpose of automatic driving of agricultural vehicles along the boundary line, reduces the labor intensity of the operation, and improves the quality of the operation.

[0068] Using the process channel module (100) of the construction system of the present invention, the angle sensor (111) installed on the steering wheel shaft of the agricultura...

Embodiment 3  application Embodiment 2

[0075] Refer below Figure 8 Introduce application example 2 of the present invention--concentrated pneumatic precision seed metering device (002) seeding rate control:

[0076] Concentrated pneumatic precision seed metering device (developed by the Engineering College of Huazhong Agricultural University, patent number 2009100610887, authorized date January 26, 2011) relies on the rotation of the seeding disc to allow the rapeseed to obtain sufficient centrifugal force and then reach the position of the hole for seeding. , The amount of seeding increases with the increase of the speed. This application is to use the measurement and control system to realize the control of the speed of the centrifugal seeding disc through real-time detection of the speed of the rapeseed live broadcast machine, and then realize the control of the seeding amount and achieve the consistency of seeding.

[0077] Utilize the process channel module (100) of the system designed by the present inventio...

Abstract

The invention belongs to the technical field of agricultural measurement and control, and particularly relates to an agricultural equipment parameter measurement and control system. Various sensors can be utilized by the system for collecting various kinds of signals in the process of operation of agricultural machines, and after conditioned, the signals are connected into a multifunctional data collection card or process channels of a single chip microcomputer system to conduct real-time collection, analyzing and processing. The system can set up a secondary measurement and control mode of an upper computer, a secondary measurement and control mode of a lower computer, and a direct measurement and control mode of a single chip microcomputer or a computer through a configured industrial touch tablet computer and the single chip microcomputer system. Reuse of a multichannel input process channel and a multichannel output process channel can be achieved through the configuration of a flexible wire jumper, a short circuit and software, and the process channels are combined with a stepping motor driving interface configured by the system so as to achieve real-time detection and control over various kinds of parameters of the agricultural equipment. The system has the advantages that the structure is compact, more than ten process channels can conduct synchronous collection and output, the debugging is easy and reliable, and the signal processing is accurate and rapid.

Description

technical field [0001] The invention relates to an agricultural equipment parameter measurement and control system, which belongs to the technical field of agricultural measurement and control. Background technique [0002] After years of development, the level of agricultural mechanization in my country has been significantly improved, and the intelligentization of agricultural machinery is gradually becoming the trend of agricultural development today. Traditional agricultural machinery can no longer meet the needs of modern agricultural development in many aspects. The present invention aims to provide real-time collection, analysis, and processing of the working state parameters of agricultural machinery for structural optimization of agricultural machinery, power consumption distribution, and intelligent improvement. A more general measurement and control platform. [0003] The measurement and control parameters in the multi-parameter measurement and control system inc...
