A kind of farm irrigation reservoir liquid level real time monitoring device
Technical field
The utility model belongs to agricultural monitoring apparatus field, particularly a kind of farm irrigation reservoir liquid level real time monitoring device.
Background technology
Along with society and scientific and technological progress, a general orientation that develops into China's agricultural development of large-scale agricultural base, large area mechanized cultivation, can obtain maximum value with minimum labour and material consumption, greatly improves farm labor efficiency and economic benefit.Certainly, in large area mechanized cultivation process, must conscientiously carry out planning management, management of labour, financial management and the engineering management work of mechanization production, only like this, could bring into play to greatest extent the advantage of mechanization of agriculture, obtain due effect.
In the mechanization production process of large-scale farm, crops high-efficient irrigation is an extremely important job.It should belong to the link of automatic management.In this important management link, the real time on-line monitoring of farm irrigation reservoir middle water level is undoubtedly to a major issue of farm automatic monitoring.Reason is very simple, and on the one hand, large-scale acreage of farm is all very large, need to lay in a large amount of water and carry out irrigate crops, and no margin for error, wastes time and energy and manually watch management.On the other hand, because the supplementary cycle of the water yield in reservoir is longer, and be generally placed on the place distant from caretaker room, and reservoir different location water level situation difference, if thereby managerial personnel can not obtain understanding in real time and comprehensively to the situation of water level, probably cause crops to lack required moisture, down to crop production reduction, even crops are withered, and then the infringement that brings interests to user.And the intelligent monitoring device of current domestic this respect does not almost have.

Embodiment
Below with reference to accompanying drawing, the technical solution of the utility model is elaborated.
System architecture schematic diagram of the present utility model as shown in Figure 1, a kind of farm irrigation reservoir liquid level real time monitoring device, comprise data acquisition and transmission system and data monitoring and display system, described data acquisition and transmission system are placed in farm reservoir, and data monitoring and display system are placed in monitoring chamber, farm; Described data acquisition and transmission system comprise several subsystems, and each subsystem comprises the data acquisition module, signal processing module, data conversion module and the wireless sending module that connect successively; Described data monitoring and display system comprise microcontroller and the wireless receiving module being attached thereto respectively, clock module, input and display module and alarm module, realize the data transmission between data acquisition and transmission system and data monitoring and display system by the radio communication between wireless sending module and wireless receiving module.In the present embodiment, described data acquisition module adopts PTH601 liquid level sensor, be used for detecting the water level of reservoir and export with electric signal, described signal processing module is amplifying circuit and the double operational bandpass filter connecting successively, for nursing one's health the electric signal of sensor output, described data conversion module adopts AD7794 digital to analog converter, described wireless sending module and the wireless receiving module employing SI4463 radio receiving transmitting module stated, described microcontroller is low-power consumption MSP430 microcontroller, described clock module is low-power consumption DS1302 chip, described input and display module adopt ALIENTEK TFTLCD, described alarm module adopts the acoustooptic alarm system of light emitting diode and hummer composition, light emitting diode has red, orange, yellow three kinds of colors, for carrying out the warning of different brackets.
Workflow of the present utility model is: first, be opposite to data monitoring and the display system initialization of farm sensing chamber, the threshold value of 3 different journey grades now can be set online by ALIENTEK TFTLCD touch-screen.PTH601 liquid level sensor is given signal processing module by the reservoir liquid level signal measuring and is processed, AD7794 every one-period to signal sampling after treatment and carry out analog to digital conversion, the signal data that is converted to digital signal sends the SI4463 wireless receiving module that is positioned at farm sensing chamber to by SI4463 wireless sending module, and send microcontroller MSP430 to, the signal data receiving is given ALIENTEK TFTLCD touch-screen by microcontroller MSP430, show reservoir liquid level, and whether the signal data that judgement collects is lower than the threshold value of setting, if be less than max-thresholds and be greater than Second Threshold, now the amber light of alarm module is bright, be greater than minimum threshold if be less than Second Threshold, orange lamp is bright, if be less than minimum threshold, the urgent sounding alarm of when red and hummer.
The involved software program of the utility model is all known, and the utility model does not relate to the improvement to any software program.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain.
