Embodiment Construction

[0171] Below in conjunction with accompanying drawing, structure principle and working principle of the present invention are described in detail:

[0172] see Figure 9 , Figure 9 It is a flow chart of the method of the present invention. The method for measuring grain yield distribution information of the present invention is used to obtain yield distribution information of grain crops in the field when harvested by a combine harvester, including:

[0173] a. The step of measuring the grain flow, which is used to set the grain conveying mechanism on the combine harvester and transport the measured grain through the grain conveying mechanism, and obtain the weighing information according to the weight signal acquisition device installed on the grain conveying mechanism Statistics of the grain flow passed through to obtain the grain flow data;

[0174] b. The step of correcting the flow data, used for the real-time grain moisture monitoring information measured by the rota...

Abstract

The invention relates to a grain yield distribution information measurement method and device, which are used for acquiring yield distribution information of grain crops in the field by utilizing an additional grain yield measurement device at the same time of harvesting grains by using a combined harvester. The method comprises the following steps of: metering the grain flow rate, wherein a grain conveying mechanism is arranged on the combined harvester and used for conveying metered grains, and a weight signal acquisition device arranged on the grain conveying mechanism is used for acquiring weighing information so as to calculate the flow rate of the grains which pass through the grain conveying mechanism to obtain the grain flow rate data; and correcting the flow rate data, wherein the grain flow rate data is corrected according to the rotating speed of the grain conveying mechanism, the traveling speed of the combined harvester and real-time grain moisture monitoring information measured by a moisture measurement device arranged below the grain conveying mechanism so as to obtain corrected grain flow rate data; and recording and outputting the grain flow rate data.

Description

technical field [0001] The invention relates to the technical field of automatic control of precision agricultural machinery and equipment, in particular to a method and device for measuring grain yield distribution information. Background technique [0002] Today, the combine harvester has become the main agricultural machinery widely used in my country. The research on the real-time monitoring technology of the harvesting and feeding of the combine harvester can adjust the operation status in time, avoid abnormal damage to the working parts, and achieve high efficiency, reduce losses and improve reliability. It has very important social and economic value. On the other hand, the problem of metering and charging for cross-regional operation of combine harvesters and the lack of on-site testing and evaluation methods in supervision and inspection departments are more prominent. The research on automatic airborne grain flow metering technology and real-time monitoring system f...
