Problems solved by technology

Unsatisfactory reliability and measurement accuracy due to large changes in grain density and weak anti-dust pollution ability of photoelectric sensors
The radiation measurement system determines the grain yield by measuring the attenuation degree of the ray after penetrating the grain flow. It has high precision, but it is generally seldom used because of the complexity of auxiliary equipment and radioactive pollution.
There is no domestic research literature on the impulse system

Embodiment Construction

[0014] Such as figure 1 , 2 As shown, the present invention includes: a main control system 1, a stabilized power supply 2, a walking speed sensor 3, an impulse sensor 4, a humidity sensor 5, a header sensor 6, a GPS sensor 7, a wireless transmission module 8 and a grain hoist speed sensor 9 . The connection method is as follows: the main control system 1 and the stabilized power supply 2 are set in the cab of the harvester and connected by wires, and the walking speed sensor 3 is set above the front drive wheel shaft of the harvester to measure the number of wheel rotations and transmit it to the main control system 1 , after being processed by the main control system 1, the walking speed of the harvester is obtained. The impulse sensor 4 is set at the exit of the grain hoist on the top of the grain cabin to measure the impulse generated by the grain flow coming out of the grain hoist in real time. The humidity sensor 5 is set inside the grain cabin Facing the exit of the g...

Abstract

An intelligent yield estimating system based on remote data transmission is composed of master control system, voltage-stabilized power supply, running speed sensor, impact sensor for measuring the impact of grains stream, humidity sensor for measuring the humidity of grains, harvesting bench sensor, GPS sensor, speed sensor for grains lifting unit, and radio transmission module.

Description

technical field [0001] The invention relates to a measurement system in the field of information technology, in particular to an intelligent production measurement system based on remote data transmission. Background technique [0002] The current production measurement system generally includes two types: remote sensing measurement and on-line measurement. Among them, remote sensing measurement includes satellite remote sensing and aerial remote sensing, which are generally only used for total production assessment due to low resolution and poor accuracy. The online measurement is to measure the yield in real time while the combine harvester is working, so the resolution is high. Commonly used online measurement systems include: volumetric measurement system, which uses photoelectric sensors to measure the grain thickness of the scraper elevator to determine the output. Due to the large variation of grain density and the weak ability of the photoelectric sensor to resist ...
