Operation-region automatic identification and area measurement system of cross-regional operation machinery and method

Abstract

The invention provides an operation-region automatic identification and area measurement system of cross-regional operation machinery and a method. The operation-region automatic identification and area measurement system comprises an ARM9 series embedded central processing unit, a cross-regional operation area measurement module, a power module, a GPRS network communication module, a storage module, a detection module and a remote monitoring display module. The cross-regional operation area measurement module comprises a GPS positioning module, an operation region and non-operation region automatic identification module and an area measuring module, and the GPS positioning module enables positioning information to be transmitted into an ARM9 embedded processor; the ARM9 embedded processor is used for processing the positioning information and calculating the corresponding operation area and cost; the GPRS network communication module is used for transmitting measurement data to the remote monitoring display module in real time. Area and cost calculation is completed rapidly. Measurement is conducted rapidly, the situation that a payment dispute occurs between a lease broker and a farmer due to the area of farmland can be avoided, the requirements for low prices, simple operation and use convenience are met, and accurate bases are provided for operation costs of cross-regional agricultural machinery.

Description

technical field [0001] The present invention mainly relates to the field of agricultural machinery for cross-area operation, in particular to a system and method for automatic identification and area measurement of remote operation areas for cross-area operation machines, which are mainly used for the identification of the operation area and non-operation area of ​​agricultural machinery for cross-area operation Automatic identification, and automatic measurement of the working area, and realize billing and simultaneous management of multiple machines. Background technique [0002] The traditional farmland area is mostly measured with a tape, which is simple and practical, but the main problem is that it is only suitable for small rectangular fields. For large fields, it is time-consuming, laborious, error-prone, and difficult to measure irregular fields. area. [0003] With the development of modern science and technology, the requirements for agricultural modernization ar...

Problems solved by technology

[0005] In order to solve the above problems, the present invention discloses a system and method for automatic identification and area measurement of remote cross-regional operation machines. For low-level problems, the design proposes processing based on compound filtering and smoothing iterative algorithms, and corrects positioning data through static and dynamic tests; for cross-area operation machinery, the GPS positioning trajectory is realized through a self-designed strip scanning positioning point algorithm Automatic identification, regardless of the shape of the field, the system can identify the operating area and non-operating area of ​​the machine through the analysis of the positioning point, and then calculate the area of ​​the scanned operating area, and transmit the data in real time to the VB6.0-based development platform through GPRS. The upper computer monitoring software is used for remote monitoring, thereby effectively improving the intelligence of the system, the convenience of remote management and the accuracy of area measurement
