The purpose of this utility model provides a kind of combine that can in time report to the police and spills the grain warning device when combine operation breaks down.
The utility model adopts following technical proposals: a kind of combine spills the grain warning device, it is characterized in that: comprise cereal detecting sensor and grain cleaning monitor, described grain cleaning monitor comprises first telecommunication circuit, CPU, warning circuit; The signal output part of cereal detecting sensor is connected with the signal input part of first telecommunication circuit, the signal output part of first telecommunication circuit is connected with the signal input part of CPU, and the signal output part of CPU is connected with the signal input part of warning circuit.
Described cereal detecting sensor comprises left, center, right three road cereal pulse signal acquisition shaping circuits, processor and second communication circuit, the output of three road cereal pulse signal acquisition shaping circuits is connected with the signal input part of processor respectively, the signal output part of processor is connected with the signal input part of second communication circuit, and the signal output part of second communication circuit is connected with the signal input part of first telecommunication circuit by the four-core wire harness.
Described warning circuit comprises buzzer alarm circuit and light emitting diode warning circuit.
The signal output part of described CPU is connected with key circuit.
The signal output part of described CPU is connected with No. three LCDs by liquid crystal driver circuit.
Described first telecommunication circuit and second communication circuit constitute by communication chip (MAX232).
After the utility model adopts such scheme, when combine carried out operation, if serious spilling grain and run the grain situation takes place, this warning device will be received and spill the grain signal and carry out sounding and lighting alarm, thereby remind the tractor driver, make the tractor driver in time find fault and solve a problem promptly.So not only can improve the job scheduling and the results efficient of combine greatly, and avoid unnecessary grain economy loss.

Fig. 2 is the circuit block diagram that the utility model two-story valley quality testing is surveyed sensor.
Embodiment
As shown in Figure 1, the utility model combine spills the grain warning device and comprises cereal detecting sensor and grain cleaning monitor, and described grain cleaning monitor comprises first telecommunication circuit, CPU (single-chip microcomputer MEGA48), warning circuit; The signal output part of cereal detecting sensor is connected with the signal input part of first telecommunication circuit, the signal output part of first telecommunication circuit is connected with the signal input part of CPU, and the signal output part of CPU is connected with the signal input part of warning circuit.Described warning circuit comprises buzzer alarm circuit and light emitting diode warning circuit.The signal input part of CPU also is connected with key circuit, and signal output part also is connected with No. three LCDs by liquid crystal driver circuit (HT1621).
As shown in Figure 2, the cereal detecting sensor comprises a left side, in, right three road cereal pulse signal acquisition shaping circuits, processor (ATMEGA48) and second communication circuit, the signal output part of three road cereal pulse signal acquisition shaping circuits is connected with the signal input part of processor respectively, the signal output part of processor is connected with the signal input part of second communication circuit, the signal output part of second communication circuit is connected by the signal input part of wire harness with first telecommunication circuit, wherein wire harness is the four-core wire harness, wherein two cores are used for cereal detecting sensor and grain cleaning monitor are powered, and other two cores are used for carrying out data communication.First telecommunication circuit and second communication circuit all adopt communication chip MAX232, have long transmission distance, characteristics that antijamming capability is strong.
Operation principle of the present utility model: when using the utility model, the cereal detecting sensor is installed in the back lower place of combining machine vibration tail sheet by assembly bracket, can eliminates the interference of combine self vibration by some glissandoes.The grain cleaning monitor is installed in driver's cabin inside, links to each other by wire harness with the output of cereal detecting sensor, and four-core wire harness length can reach 8 meters.After combine was started working, the dc source on the combine was given grain cleaning monitor and the power supply of cereal detecting sensor, and grain cleaning monitor and cereal detecting sensor are started working.As shown in Figure 1 and Figure 2, the data of the unrestrained cereal of vibration tail sheet are gathered by three road cereal pulse signal acquisition shaping circuits of the left, center, right in the cereal detecting sensor, and high-tension cereal pulse signal is shaped as the signal that processor can receive is transferred to processor; After processor is handled and is integrated the cereal signal that receives, data are carried out level conversion by the second communication circuit after, send to the grain cleaning monitor by the signal output part of second communication circuit by the four-core wire harness.The grain cleaning monitor is received the data that the cereal detecting sensor sends, and elder generation passes to CPU with data after carrying out level conversion by first telecommunication circuit then; After CPU is handled to received signal cereal is detected data show on No. three LCDs.
The grain cleaning monitor shows according to the image data that receives, when the cereal percent of loss hour, the grain cleaning monitor enters " normally " state, green LED is bright; When the cereal percent of loss was big, the grain cleaning monitor entered " alert state ", and yellow light-emitting diode is bright; When cereal percent of loss severe overweight, the grain cleaning monitor enters " warning " state, and red light emitting diodes glimmers, and buzzer intermittently reports to the police, and reminds the operation tractor driver to note, guarantees the operate as normal of grain header.Can select per mu yield (greater than 900 mu/jin with less than 900 mu/jin) and different crops (wheat and paddy rice) by the button that the CPU signal input part is provided with, and some parameters of grain cleaning monitor are adjusted.
