Abstract
The invention discloses a field operation examination mechanism and a field operation examination method. The field operation examination mechanism comprises a signal reflection board, a reflection board support, a signal projector and an upper computer. The signal projector is mounted on an examining vehicle. When an examination starts, the upper computer transmits number-fetching commands continuously in a wireless mode; distance between the vehicle and a roadside benchmark is measured, and measured distance value is transmitted to the upper computer; the upper computer performs data processing according to the measured distance value, performs measurement by utilizing of the signal projector, continuously measures the distance between the examining vehicle and the roadside benchmark and transmits a result to the upper computer for processing in the wireless mode to judge turning-around deviation and running parallel deviation of the examining vehicle. The field operation examination mechanism is high in degree of automation and high in measurement accuracy, so that timeliness for acquiring data can be guaranteed by adopting wireless transmission.
Description
Technical field
The invention belongs to tractor technical field of measurement and test, relate in particular to a kind of farm work examining body and method.
Background technology
Along with science and technology and social development, the mechanization degree of agricultural is also more and more higher, and many farm works have replaced manual operation in the past by mechanically actuated, as the sowing of wheat and harvesting.In various farm works, there is the operation that much needs control operation gap and parallel deviation, as the sowing of corn.This just requires operator when control machinery carries out operation, has consummate technology, to reach desirable plantation gap and density.In current farm work examination, be mainly to rely on examiner's subjective judgement to determine examinee's operant level, usually can cause examinee's total marks of the examination defective because of reasons such as the collimation errors, lack certain cogency.
Summary of the invention
The present invention is directed in current Field-working Tractor-implement examination; mainly to rely on examiner's subjective judgement to determine examinee's operant level; usually can cause examinee's total marks of the examination defective because of reasons such as the collimation errors; lack certain problems such as cogency, propose a kind of farm work examining body.
The embodiment of the present invention is achieved in that a kind of farm work examining body, and this farm work examining body comprises signal reflex plate, reflecting plate support, signal projector, host computer;
Several reflecting plate supports are arranged and are fixed on the ground as requested, and signal reflex plate is arranged on reflecting plate support; Testing vehicle is provided with signal projector, and signal projector and host computer carry out wireless telecommunications.
Further, signal projector adopts ultrasonic distance measuring module.
Another object of the embodiment of the present invention is to provide a kind of farm work method of examination, and this method of examination comprises the following steps:
Signal projector is arranged on testing vehicle;
Enter after examination, host computer sends retrieval command continuously by wireless mode;
Measure the distance between car and roadside benchmark, and measuring distance value is sent to host computer;
Host computer is done data processing according to measuring distance value, the error of advancing during judgement examination vehicle travels.
Further, described roadside benchmark is comprised of reflecting plate support and signal reflex plate.
Farm work examining body provided by the invention and method, utilize signal projector to measure, the distance of continuous coverage testing vehicle and limit, place benchmark, pass through wireless transmission method, result is sent to host computer and process, thereby judge turn around deviation and the travel parallel deviation of examination vehicle in advancing.This structure automaticity is high, and without manual measurement distance, measuring accuracy is high, and adopts wireless transmission, guarantees the real-time of image data.
