Abstract
A digital grain condition detection apparatus comprises a sensor, data signal conversion chips, a gauge rod, a CPU, a display circuit, and an LED screen, and is characterized in that the data signal conversion chips are arranged in the sensors, the sensors are evenly distributed in the gauge rod and parallelly connected with the CPU, and the CPU integrates data and then outputs the data via the display circuit and the LED screen. Conversion from a weak electricity signal to a data signal is realized in the sensors, and a digital value is directly outputted, thus solving the problems of long distance transmission of signals and reduced precision caused by interference and attenuation during the transmission process. A monitoring earphone is added to assist the detection of grain pest activities, thus improving the accuracy.
Description
Technical field
The utility model relates to a kind of electron detection device, specifically relates to a kind of digital grain information detection device.
Background technology
By Gu so far, the whether proper economy to country of the storage of silo grain can be normally reasonably operation very big influence is arranged.But former economy and scientific and technological level are limited, and be so the environment of the storage of China's grain is very poor, backward in management.
Early stage grain condition monitoring mainly adopts the thermometer measure method, and it is that thermometer is put into special inserted link, rule of thumb is inserted in a plurality of points for measuring temperature of grain heap; Managerial personnel regularly extract reading, confirm the high and low of grain temperature, and whether decision grain; This method has certain effect to grain storage, but owing to the reasons such as human factor of thermometer precision, artificial reading, temperature detection not only speed is slow; And precision is low; It is not thorough to sample, and the too high difficult quilt of local grain temperature is in time found, causes happening occasionally because of local grain moldy metamorphism causes the situation of bad grain of large tracts of land.
Along with development of science and technology; The grain industry has been developed the multiple instrument and equipment that is used to detect the foodstuff preservation state, comprises Moisture Meter, gas detecting instrument, temperature monitor etc., and each point for measuring temperature of each grain depot is gone the rounds to detect; Detection speed, precision improve greatly; Reduced labour intensity, yet mostly this detecting instrument is to adopt the mode of dial plate, pointer to show the grain feelings because dial plate, pointer sensitivity is low and signals transmission in be interfered easily and decay; Cause accuracy of detection, reliability all not ideal enough, become a big hidden danger of safe grain storage.
Summary of the invention
The utility model proposes a kind of digital grain information detection device for addressing the above problem, and this device has solved the problems such as precision reduction because of disturbing and decaying and cause in the signals transmission, has improved accuracy, stability that the grain feelings detect greatly.
The utility model is realized through following technical proposals:
A kind of digital grain information detection device; Comprise sensor, data-signal conversion chip, feeler, CPU, display circuit, LED screen; It is characterized in that said data-signal conversion chip places in the said sensor, said sensor is evenly distributed in the said feeler and is connected with said CPU in parallel; Said CPU integral data is then through said display circuit and the output of said LED screen.
As a kind of prioritization scheme of the utility model, a kind of digital grain information detection device is characterized in that, also comprises monitoring headpone.
The utility model is compared in traditional grain information detection device has following advantage:
One of which, the utility model are realized the transformation of weak electric signal to data-signal in sensor, directly spread out of digital quantity, thereby have solved in signal long-distance transmission problem and the transmission course because of the problems of disturbing and decay causes such as precision reduction.
Two, the utility model has added monitoring headpone, and the auxiliary detection movable to grain insect pest improved accuracy.
Description of drawings
Accompanying drawing is the utility model block diagram;
Among the figure: 1-sensor, 2-data-signal conversion chip, 3-feeler, 4-CPU, 5-display circuit, 6-LED screen, 7-monitoring headpone.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
A kind of digital grain information detection device; Comprise sensor 1, data-signal conversion chip 2, feeler 3, CPU4, display circuit 5, LED screen 6; It is characterized in that said data-signal conversion chip 2 places in the said sensor 1, said sensor 1 is evenly distributed in the said feeler 3 and is connected with said CPU4 in parallel; Said CPU4 integral data is then through said display circuit 5 and said LED screen 6 outputs.
As the another kind of prioritization scheme of the utility model, a kind of digital grain information detection device is characterized in that, also comprises monitoring headpone 7.
The utility model sensor 1 comprises temperature sensor, humidity sensor, acoustic sensor; In use; Feeler 3 is inserted in the grain heap to be detected, and by sensor 1 acquired signal, data-signal conversion chip 2 changes weak electric signal into data-signal in sensor 1; Directly outputting data signals is to CPU4; The CPU4 integral data feeds back to the staff through said display circuit 5 and said LED screen 6 with the grain feelings then, and the staff can be with monitoring headpone 7 auxiliary judgement grain insect pest active situation simultaneously.
Claims (2)
