Description
Technical field
The present invention relates to a kind of agricultural machinery technological field, is a kind of sow information and to the monitoring system of broadcast leakage zone marker of sugarcane planting machine of monitoring.
Background technology
Plantation is that the demand labour is many in the present sugarcane production of China, the mechanization level is low and then restricts one of critical process of Mechanization Development.Several kinds of sugarcane planting machines of China's development are in experimental study, and it is discontinuous in the process of using, to exist the feeding worker to operate, and causes the problem of broadcast leakage easily, and reseed and need wait until that the sugarcane seedling just can carry out after longer.Be different from seed shape seed, the sugarcane kind is longer, broadcast leakage occurs and will have a strong impact on sugarcane yield.Therefore sugarcane broadcast leakage monitoring system will play an important role with the development that promotes planter mechanization to improving the sugarcane planting machine operation quality.
Summary of the invention
Do not have the defective of supporting monitoring system to present China sugarcane planting machine, the purpose of this invention is to provide a kind of to sugarcane broadcast leakage monitoring accurately and can carry out the system of broadcast leakage mark in real time.
To achieve these goals, the present invention adopts following technical scheme:
A kind of sugarcane planting machine broadcast leakage monitoring system; Comprise sugarcane planting machine; Also comprise sensor, central processing module, mark module, power module, the output of said sensor is connected with the input of central processing module, and the output of central processing module is connected with the input of mark module; Power module is respectively to central processing module, mark module power supply.
Sensor is installed in the sow both sides of pipe minor face of sugarcane planting machine, and sensor covers the region area that sugarcane falls, and when the sugarcane kind fell, sensor promptly sent signal and is sent to central processing module.Central processing module is according to judging whether broadcast leakage the blanking time that the sugarcane kind falls kind, leaks kind then sends control signal and give the broadcast leakage mark module if having.Mark module spreads marking objects according to control signal broadcast leakage mark module at plantation row side.
Native system adopts sensor can cover the region area that the whole sugarcane of monitoring falls, as long as the sugarcane kind falls just can monitor, and can not judge other impurity by accident.
Said central processing module comprises and is used for the work initial module whether monitoring sensor has pulse to produce, and is used to calculate the counting module in the time interval that adjacent sugarcane kind falls, and is used to monitor the broadcast leakage monitoring modular of sugarcane kind whereabouts information.The output of work initial module is connected with the input of counting module, and the output of counting module is connected with the input of broadcast leakage monitoring modular.When pulse produces, judge that sugarcane planting machine begins plantation, the initialization of work initial module, counting module is started working, otherwise continues to wait for; Whether the broadcast leakage monitoring modular exceeds preset interval time according to the pulse interval time judges whether broadcast leakage; And the whereabouts information of sugarcane kind arranged through the bright indication of indicator lamp; The working condition of mark module and the state of power module reach the effect of being convenient in time pinpoint the problems.
Said broadcast leakage monitoring modular comprises data transmission module, and said data transmission module is used to transmit the time interval that time that the sugarcane kind sows and sugarcane kind are sowed.Various information comprises the working condition of the time interval, mark module working condition and the power module of sugarcane kind whereabouts in twos.
Said mark module is made up of housing, roller set, running part, motor, carrying case; Roller set is fixed on the housing by axle and bearing block, and sprocket wheel on the axle and motor are through chain drive power, and wheel rolls group through gear drive.Carrying case is fixed by bolts to the housing top.The roller set reverse rotation is stirred the label that loads in the casing to both sides, label gets into roller and loads the space between the casing, falls under arriving when being rotated further.
The motor of mark module is controlled start-stop according to control signal by driver module, and is mandatory with label row down through two roller backward rotation in the roller set.Can adjust the amount of sowing through changing rotating speed as required.Carrying case loads label and can supply the omnidistance minimizing loading number of times that uses of one-stop operation to reduce labour intensity.The color of label is selected for use with the big identification easily of soil difference and to the free of contamination material of soil in the mark module.
Said power module is the accumulator or the independent power supply of sugarcane planting machine; Power module is supplied power to the motor of central processing module and mark module respectively; Power module comprises straightening and filtering unit and apparatus for protecting power supply.Because the required electric current of motor of mark module is bigger, for preventing that influencing central processing module in the start-up course normally uses, power supply divides two parts processing to supply with central processing module and motor respectively, and does rectifying and wave-filtering, and power protection is handled.
Driver module drove the motor of mark module afterwards by two FET parallel connections, so the big electric current shunting of motor and FET was furnished with fin and can strengthens functional reliability and stability greatly.
Said monitoring system also comprises driver module, and the output of central processing module is connected with the input of driver module, and the output of driver module is connected with the input of mark module; The output of driver module is connected with the motor of mark module.
Said monitoring system is PC also, and central processing module is connected with PC through data transmission module; Sugarcane planting machine broadcast leakage monitoring system will be saved in PC blanking time in real time.
The present invention adopts sensor, can all cover the region area that sugarcane falls.Sugarcane kind length is generally about 350-400mm, and sensor will send electric impulse signal in the dropping process, and this monitoring system is calculated the blanking time between the sugarcane kind according to pulse signal, leaves sensor from the preceding paragraph sugarcane kind and begins to get into end to next section sugarcane kind.System will reach PC through serial communication in real time and preserve data blanking time; And according to judging whether broadcast leakage blanking time; If surpass the time interval that broadcast leakage defines then output signal to mark module, start mark module and spread down label and when sugarcane kind whereabouts is arranged, stops.Monitoring result of the present invention is accurate, can to cane planting monitor in real time and can and tense marker broadcast leakage position and distance conveniently reseed, can effectively remedy because the sugarcane underproduction that causes of broadcast leakage.
