Background technology
China is Rice Production state maximum in the world and country of consumption, and national rice yield accounts for 40% of cereal crops gross yield, and Monitoring of Paddy Rice Plant Area reaches more than 3,000 ten thousand hm
2, account for 28% of the national cereal crops gross area, for China's grain security and national security provide powerful guarantee.And the plantation of paddy rice needs the support of great lot of water resources, China's paddy rice water consumption accounts for more than 45% (having data to claim more than 50%) of total water consumption, and can be rated as the whole society first uses water rich and influential family.But China's agricultural water resources is very short, and along with expanding economy, the frequent generation of water contamination accident, degree of water shortage is more and more serious, and lack of water increasing extent is large, and water crisis more and more approaches to us.Further urgent with the water-saving irrigation of water rich and influential family as the whole society first.Existing conventional rice field irrigation method is " light irrigation stores deeply " or " storing in light irrigation " mode, namely carries out shallow irrigation, precipitation then deeply store or in store.By manual adjustment, field water layer depth is controlled between suitable water layer is upper and lower.Be characterized in that paddy rice is in whole breeding time, except late tillering state once falls except dry (overboard dry field), all there is water layer in all the other stage fields.
Because different field height is different, current irrigation method is by irrigation canals and ditches, makes the horizontal plane that the water level of each field reaches identical, and the water level in the farmland of reality cannot reach the water level of expectation due to the height reason of field.
Summary of the invention
The object of the present invention is to provide a kind of paddy rice Precision Irrigation TT&C system based on wireless sensor network and method, irrigate with the water-saving precision realizing paddy rice.
In order to solve above technical problem, the present invention obtains farmland water level by level sensor, and controls the water level of different field by magnetic valve, and irrigate with the water-saving precision realizing paddy rice, the concrete technical scheme of employing is as follows:
Based on a paddy rice Precision Irrigation TT&C system for wireless sensor network, it is characterized in that: comprise farmland water level sensor (1), wireless sensor network transport module (2), data server (3), water pump controller (4), magnetic valve (5), water pump (6);
Described farmland water level sensor (1) is deployed in different field and also connects and composes farmland water level information gathering network with wireless sensor network (2) respectively; Wireless sensor network (2) is connected with data server (3), for by gathered farmland water level information transmission to data server (3); Data server (3) requires to judge current farmland water level whether within range of set value according to the water level in the requirement of rice cropping setting farmland, if lower than setting value, data server (3) sends water pump open command feed pump controller (4) to open water pump (6) by wireless sensor network (2), send open command to the magnetic valve (5) that farmland water level sensor (1) is corresponding simultaneously, realize the accurate control of farmland water level.
According to the investigating method of described a kind of paddy rice Precision Irrigation TT&C system based on wireless sensor network, it is characterized in that comprising the following steps:
Step one, utilizes farmland water level sensor (1) to obtain the water level information data of different croplands field;
Step 2, utilizes wireless sensor network transport module (2) that described water level information data are transferred to data server (3);
Step 3, utilizes data server (3) according to obtained water level information data, and farmland water level setting value, determines field irrigation amount;
Step 4, is sent to water pump controller (4) and magnetic valve (5) by wireless sensor network transport module (2) by irrigation control instruction, thus realizes the water lev el control of different croplands field.
Described according to obtained water level information data, and farmland water level range of set value, determine that field irrigation method for determination of amount is as follows:
Judge that the water level of each field is whether within described farmland water level range of set value;
If the water level of certain field is lower than the lower limit of described farmland water level setting value, water pump open command is then sent to water pump controller (4) by wireless sensor network (2) by data server (3), opens water pump; Simultaneously by magnetic valve (5) transmission opens solenoid valve (5) instruction of wireless sensor network (2) to the field of correspondence, open corresponding field magnetic valve, realize the irrigation of corresponding field;
When farmland water level sensor (1) collect that field water level reaches described farmland water level setting value upper in limited time, data server (2) sends out code to the magnetic valve (5) in corresponding field, closes the magnetic valve in corresponding field.
When magnetic valve (5) Close All in all fields, data server (3) feed pump controller sends the instruction that switches off the pump, to switch off the pump.
the present invention has beneficial effect
The present invention obtains farmland water level by utilizing level sensor, data server is sent data to by wireless sensor network transport module, data server is according to obtained farmland water level information and farmland water level setting value, determine field irrigation amount, and by wireless sensor network, information will be sent to water pump controller and magnetic valve, realize the water lev el control of different field, irrigate with the water-saving precision reaching differing heights paddy field.
Accompanying drawing explanation
Fig. 1 is present system structure chart;
In figure: 1 farmland water level sensor, 2 wireless sensor network transport modules, 3 data servers, 4 water pump controllers, 5 magnetic valves, 6 water pumps.
