Detailed Description
As shown in fig. 1 to 2, the multipoint monitoring and early warning device for the wheat and corn meteorological disasters comprises a lower bottom plate 11, wherein a telescopic adjusting supporting leg can be connected to the lower side of the lower bottom plate, and the balance of the lower bottom plate can be adjusted through four adjusting supporting legs arranged on the lower bottom plate. Ensure that the device is horizontal when being placed in a wheat and corn field.
The lower side of the lower bottom plate can be provided with a heavy block, so that the gravity center of the device is lowered, and the device is prevented from tipping due to rain and wind in the field.
The upper side of the lower bottom plate is provided with a plurality of fixing columns 12, guide grooves 15 are formed in the fixing columns, a lifting column 13 is arranged in the guide grooves in a sliding fit mode, the lifting column can move up and down along the guide grooves, a spring 16 is arranged between the bottom of each guide groove and the bottom of each lifting column, and the lifting columns are connected with an upper plate 14, so that the upper plate can move up and down with the help of the elasticity of the spring.
Be equipped with a plurality of sensitization modules 21 on the upper plate, the sensitization module is formed by a plurality of light sensor arrays, light sensor is connected with the control panel, and when the branches and leaves of millet maize sheltered from sunshine, the illumination sensor that the shadow of wheat maize corresponds then can not detect shining of sunshine, and then the illumination sensor output is the high-order, and the illumination sensor output that shines sunshine is the low level. Therefore, the output quantity of the illumination sensor is used for detecting the leaf area of the wheat and corn. And establishing a relevant growth model by comparing the output quantity of the illumination sensor at different times of a day.
The control panel is also connected with a wireless communication module which is widely applied to the fields of vehicle monitoring remote control and remote measurement, industrial data acquisition systems, biological signal acquisition and the like.
Wireless communication module cooperatees with unmanned aerial vehicle, be equipped with relevant receipt emission module on the unmanned aerial vehicle equally, when unmanned aerial vehicle tours to the device top, unmanned aerial vehicle's position is detected to the control panel, gives unmanned aerial vehicle with relevant illumination sensor's relevant data transmission, through unmanned aerial vehicle as the transfer station, with information transmission for people.
The upper plate is provided with a water collecting groove 22 in the middle, as shown in fig. 2, one side of the water collecting groove is provided with a butt joint groove 23, the other side of the water collecting groove corresponding to the butt joint groove is provided with an inner cavity 24, one side of the inner cavity is sealed by a movable sealing plate 25, and the movable sealing plate can move to the butt joint groove of the other side of the water collecting groove, so that the upper side of the water collecting groove is sealed by the movable sealing plate.
The inner cavity 24 is communicated with the air blowing and sucking mechanism through a first air passage 26. By blowing air to the first air passage, the pressure in the inner cavity is increased, so that the movable sealing plate is moved to the left in the butt joint groove, and the water collecting tank 22 is sealed.
And a second air channel is arranged on the lower side of the first air channel in parallel and is used for communicating the water collecting tank with the air blowing mechanism.
The catch basin bottom is equipped with a plurality of pressure water mechanisms, pressure water mechanism includes left sheet rubber 28 and right sheet rubber 29, left side sheet rubber closely laminates with right sheet rubber.
When removing shrouding shutoff catch basin upper portion, if there is ponding in the catch basin, then the mechanism of blowing blows to second gas circuit passageway for pressure increase in the catch basin, and left sheet rubber and right sheet rubber can leak from this department under the condition of pressure grow. So that the water quantity in the water collecting tank is reduced.
When it rains, the water collection tank accumulates a certain amount of water per unit time, and the amount of water presses the spring 16, so that the distance between the lifting column and the guide groove changes.
Furthermore, a pressure sensor is arranged at the bottom of the spring, and the rainfall is judged by detecting the change condition of the pressure.
If it rainstorm occurs, the water collecting tank is filled with water per unit time, and the spring pressure is rapidly changed, so that it is known that the rainstorm occurs. Then the air blowing and sucking mechanism and the air blowing mechanism are controlled to act, so that the water is emptied.
If the wind blows, the distance between the lifting column and the bottom of the guide groove is changed continuously, and the pressure change of the spring is large or small. The pressure change that arouses through the spring can realize judging whether to blow wind or rain, and the spring is ingenious in design in this department, and the cost is also low.
A second embodiment is shown in figures 3 and 4,
be equipped with distance sensor transmitter 31 bottom the lift post, be equipped with distance sensor receiver 32 bottom the guide way, the distance sensor transmitter cooperatees with distance sensor receiver, through distance sensor's design, can detect the distance change between lift post and the guide way, more image, quantization.
A vertical channel 41 is also arranged in the fixed column 12, and the bottom of the vertical channel is communicated with the outside through a horizontal channel 42. Humidity sensors 43 are provided at different heights in the vertical channel. When it rains heavily, the water quantity entering the vertical channel is small by using the principle of the communicating vessel, and the height of the water level is detected by the humidity sensor.
In the working mode, when natural disasters occur, such as strong wind, the strong wind can blow the upper plate to move up and down, so that the pressure sensor positioned on the lower side of the spring or the distance sensor positioned in the guide groove is correspondingly changed, and the situation that the strong wind comes is known. And judging the time of the strong wind through the time of the relevant signals. If it rains, the water collecting tank accumulates water, and the amount of water per unit time becomes a basis for judging heavy rain or light rain. And the accumulated water in the water collecting tank can be discharged by utilizing a related mechanism. If the drought is long, the pressure sensor or the distance sensor can not be changed. The equipment can also be provided with a camera which can be used for judging by taking pictures and can be used as archival data.
The control panel of the device is connected with a wireless communication module, and the wireless communication module transmits related information to a remote computer control end. The coming person awakens people from natural disasters and gives early warning.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
