Embodiment 1

[0024] Embodiment 1: as Figure 1 to Figure 3 As shown, a square baler production measurement system based on Beidou / GPS technology includes a weighing device 11, a first slave controller 4, a Beidou / GPS receiver 5, a second slave controller 7, and a master controller 8. Terminal display 6; said weighing device 11 and the first slave controller 4 are located at the end of the bale output chute 12, and the weighing device 11 includes a weighing tank 1, a load cell 2, and a support frame 3, wherein the weighing Groove 1 is lower than bale output chute 12, the distance is about 200mm, and it is in the shape of two steps; the length of square bale is less than the length of weighing trough 1, and greater than half of the length of weighing trough 1, so as to ensure that the weighing trough Only one square bale is weighed this time; the Beidou / GPS receiver 5 is located outside the tractor 10, and the second slave controller 7, master controller 8, and terminal display 6 are located...

Embodiment 2

[0026] Embodiment 2: the specific process of weighing data reading, when square straw bale falls into weighing groove 1 instant its instantaneous pressure mutation signal is recorded as this square straw bale weighing initial signal I 1 , when the square bale slides out of the weighing slot 1, its instantaneous pressure mutation signal is recorded as the final signal I of this square bale weighing 2 , wherein the first slave controller 4 reads the square bale weighing initial signal I 1 To square bale weighing final signal I 2Between the weighing sensor 2 data, measure 3 sets of weighing data, each set of 30 weighing values, use the Grubbs algorithm to remove the weighing abnormal value in each set of data, and calculate the abnormal value of each set of data After the value has been eliminated, the average value of the data is recorded as the data of this group of weighing, and the average value of the calculation of 3 groups of weighing data is recorded as the final data of...

Embodiment 3

[0032] Embodiment 3: the measurement of working area, Beidou / GPS receiver 5 gathers a latitude and longitude information per second, and the latitude and longitude information is sent to the second slave controller 7, and the second slave controller 7 reads the latitude and longitude of Beidou / GPS receiver 5 Data, the longitude and latitude data are converted into the working distance and combined with the width of the baler 9 to calculate the real-time farmland working area, and the real-time working area is transmitted to the main controller 8 through the CAN bus.

Abstract

The invention relates to a rectangular baler yield monitoring system and a yield monitoring method based on a Beidou/GPS technology, which belong to the technical field of balers. The system comprisesa weighing device for measuring the weight of a rectangular bale, a first slave controller for reading and processing data of a weighing sensor, a Beidou/GPS receiver for reading the geographical position data of the baler, a second slave controller for reading the data of the Beidou/GPS receiver and combining the breadth of the baler to calculate the working area, a main controller for reading the data of the first slave controller and the second slave controller and performing real-time yield monitoring and data storage and a terminal display with a real-time display function, wherein the weighing device and the first slave controller are located at the tail end of a bale output slideway; the Beidou/GPS receiver is located outside a tractor; and the second slave controller, the main controller and the terminal display are located inside the tractor cab. Real-time and reliable straw yield spatial distribution information corresponding to the temporal geographic position can be acquired, and a farmer can understand the harvest and manage the work field accurately.

Description

technical field [0001] The invention belongs to the technical field of balers, and relates to a production measurement system and method for a square baler baler based on Beidou / GPS technology. Background technique [0002] Our country is rich in forage resources, which are rich in various trace elements and vitamins, so it becomes the first choice for raising livestock. At present, silage harvesting machinery cuts, crushes and bundles some crop stalks. As a product of forage harvesting machinery, straw bales are not only easy to transport and stack, but also can guarantee its quality to a certain extent. Its output directly affects the production of animal husbandry. Economic benefits, the production measurement system has long been valued in Western countries. Straw bale yield measurement is the application of precision agricultural technology, and its important link is the acquisition of field crop yield information. Since the square baler is a continuous operation, the...
