step two: obtaining irrigation water quantity Gi by using a formula Gi = (1/Bi) × z1+ (1/Di) × z2, wherein z1 and z2 are preset proportionality coefficients, and the lower the soil humidity is, the larger the irrigation water quantity is; the smaller the predicted precipitation is, the larger the irrigation water quantity is;
step three: acquiring a participation value Ci and a distance difference Hi of an appointed irrigation user;
step four: obtaining a water unit price Mi by using a formula Mi = Ma + Hi k1-Ci k 2; wherein k1 and k2 are preset proportionality coefficients; ma is a water unit price basic value; the larger the distance difference, the higher the water unit price; the larger the participation value, the lower the water unit price;
step five: obtaining the water price by using a formula Fi = Gi Mi;
and the water price calculating module sends the calculated irrigation water quantity and water price of the appointed irrigation user to the database for storage.
2. The remote irrigation monitoring and control system of claim 1 wherein the data consolidation module is configured to integrate user data stored in the database, the user data including corresponding basic data, participation values, irrigation water volume and water price, the specific integration steps being as follows:
SS 1: acquiring the starting time of user data storage and the participation value of a user, and counting the total times of user data access, wherein each time of user data access, a storage list duration is obtained; obtaining an access increasing time length through the product of the total number of access times and the time length of the storage unit;
SS 2: dividing the storage time length into a plurality of grades, wherein each grade corresponds to one time length;
SS 3; each grade corresponds to a different value range; matching the participation value with the value range;
SS 4: obtaining the grade and the duration of the participation value in the corresponding value range;
SS 5: when the sum of the starting time and the duration of the user data storage and the access increasing duration is equal to the current time of the system; compressing and storing the user data;
SS 6: counting the time of starting compression and storage of user data; when the sum of the time and the duration of the start of the compression and storage of the user data is equal to the current time of the system; the user data is sent to the cloud server for storage.
3. The remote irrigation monitoring and control system as recited in claim 1 wherein the login access module is configured for a user to access user data in the database via a mobile phone terminal and to pay a water price via the mobile phone terminal.
