The remote intelligent soil moisture monitoring system comprises a central controller part, a sensor input part, a keyboard input part, an LCD (Liquid Crystal Display) display output part and a GSM (Global System for Mobile Communication) short message output part. In the utility model, the site soil moisture monitoring is free, data is collected through a remote data collecting device, then the collected data is transmitted to analysis equipment of the utility model, after the analysis, the correct soil moisture data can be obtained, and thus, farmers can conveniently improve the local soil moisture.

Description

Soil moisture long-distance intelligent monitoring system

Technical field

The utility model belongs to agriculture electronic device field.

Background technology

Aspect agricultural planting, it is crucial that the moisture of soil is regulated moderate, and it directly influences the supply of social crops, and the life of affect people's is the most important thing.Yet existing moisture monitoring equipment major part is to lean on people's experience to go range estimation, and accuracy remains textual criticism, and some monitoring equipments are arranged, but its basic need takes a sample to the scene, not only bothers but also limitation is arranged, and wastes a large amount of human resources.

Summary of the invention

The purpose of the utility model is through Long-distance Control, can monitor the soil moisture long-distance intelligent monitoring system of regional soil water regime in real time.

The utility model is made up of central controller part, sensor importation, key input section, LCD demonstration output and GSM short message output;

Soil moisture sensor J4 links to each other with central controller through P3.5;

Central controller reads keypad information through the P1 mouth, and is provided with the TEST key;

The LCD data line links to each other with 89C51 single-chip microcomputer P0 mouth, and control line RS, R/W and E link to each other with P2.7, P2.6 and P2.5 respectively;

Adopting 74F07 to act as voltage matches drives with buffering; J2 is a sim card socket; D1 is a relay indicating light, and the SYNC pin of TC35i has two kinds of mode of operations, and available AT order AT SYNC switches; A kind of is the flash-up situation of indication during emission state, and another kind is the duty of indication TC35i.

The utility model need not arrive the scene of the soil moisture that needs monitoring; Carry out image data through the remote data capture device; Then the data of gathering are dealt on the analytical equipment of the utility model; Will draw soil moisture data accurately after analysis finishes, just can make things convenient for the peasant that local soil moisture is improved.

Embodiment

The utility model is made up of central controller part, sensor importation, key input section, LCD demonstration output and GSM short message output;

Soil moisture sensor J4 links to each other with central controller through P3.5;

Central controller reads keypad information through the P1 mouth, and is provided with the TEST key;

The LCD data line links to each other with 89C51 single-chip microcomputer P0 mouth, and control line RS, R/W and E link to each other with P2.7, P2.6 and P2.5 respectively;

Adopting 74F07 to act as voltage matches drives with buffering; J2 is a sim card socket; D1 is a relay indicating light, and the SYNC pin of TC35i has two kinds of mode of operations, and available AT order AT SYNC switches; A kind of is the flash-up situation of indication during emission state, and another kind is the duty of indication TC35i.

Below in conjunction with accompanying drawing the utility model is described in detail:

Comprise central controller 89C51 part, the sensor importation, key input section, LCD shows that output and GSM short message efferent grade.

Soil moisture sensor 3 links to each other with single-chip microcomputer through P3.5; System's (for example 2 hours) central controller whenever at regular intervals reads the temperature value of each node respectively; Temperature value is 12 binary messages, converts ram cell that ASCII character is stored in the processor internal fixation into for LCD output and the form transmission of GSM with short message by central controller.

Phone number that the moisture short message is accepted in input and the setting of sending at interval etc. through the 4*4 keyboard, read keypad information through the P1 mouth, use for program.System also is provided with the TEST key, uses when supplying the start test through the mode of interrupting, as long as no matter when click the TEST key, system is just immediately to the mobile phone output of the appointment temperature of each test point at that time.

LCD adopts the 1602A display module, and data line links to each other with 89C51 single-chip microcomputer P0 mouth, and control line RS, R/W and E link to each other with P2.7, P2.6 and P2.5 respectively, shows the temperature value of the information (telephone number) and the demonstration different soil of input.

Because single-chip microcomputer voltage is 5V, and TC35I voltage is about 4V, system adopts 74F07 to act as voltage matches and buffering driving for this reason.J2 is a sim card socket, and D1 is a relay indicating light, and the SYNC pin of TC35i has two kinds of mode of operations; Available AT order AT SYNC switches; A kind of is the flash-up situation of indication during emission state, and another kind is the duty of indication TC35i, the flash-up situation that this module is used when being a kind of function emission state in back; When LED extinguishes, show that TC35i is in to close or sleep state; When LED be 600ms bright/represent when 600ms puts out that SIM does not insert or TC35i is carrying out network entry; When LED be 75ms bright/when 3s puts out, show that TC35i has logined enter the internet, is in holding state.Can know the duty of system through this pilot lamp.

The total system power supply is direct current 5V.
