Abstract
The utility model discloses a drip irrigation control system comprising a main station controller, a field controller, a valve control circuit board and an electromagnetic valve. A combination cable is connected and arranged at least between the field controller and the valve control circuit board, and the combination cable is composed of six cables including a serial sending bus, a parallel receiving bus, a testing bus and three corresponding ground wires. The connection model of the utility model is quite simple, the cost of investment is low, and mechanical intensity of the cable connection between modules is effectively improved. The utility model not only has relative strong ability of anti-interference, but also can fast find the broken wire when a wire cuts off. Moreover, the utility model has low cost of maintenance and can be easily promoted.
Description
Technical field
The utility model relates to a kind of drip irrigation control system that is used for farm environment parameter acquisition and irrigation.
Background technology
Calculator farm environment parameter acquisition and drip irrigation automation control system, be mainly used in automatic monitoring soil moisture, soil temperature, relative humidity of atomsphere, field water evaporation quantity and the isoparametric changing condition of soil total salt content, can forecast according to these parameter combined mathematical modules simultaneously needs to irritate time and needs irrigation quantity, show relevant farmland temp. and humidity changing condition, for the automatic irrigation system provides control information, transfer control signal.System's running is: the various kinds of sensors that information acquisition system is provided with according to the field, with all kinds of farm environment parameter timing acquiring once, pass to the calculator beyond several kilometers by data radio station, send the irrigation order by data radio station to main control system at a distance when providing Irrigation Forecast to irrigate as calculated after the machine system handles, the magnetic valve on the aqueduct of field is opened automatically and is irrigated.485 data/address bus that adopt carry out serial communication more between existing all kinds of each module of long-range irrigation control system, and when main line was subjected to external force that broken string takes place, whole system will local paralysis or all paralysis.Because can't accurately investigate and prosecute the broken string region, it is bigger to recover difficulty, workload is bigger, when entering the farmland and carry out scene seeking, usually causes the farmland extensive damage.
The utility model content
The purpose of this utility model is to provide a kind of drip irrigation control system, has effectively improved the mechanical strength that cable connects between each module, and not only antijamming capability is stronger, and when broken string takes place, can find the place of breaking fast.
The purpose of this utility model is achieved in that a kind of drip irrigation control system, comprise main station controller, field controller, valve control circuit plate and magnetic valve, at least between field controller and valve control circuit plate, be connected combination cable be set, said combination cable by serial send bus, parallel receive bus, testbus and corresponding ground wire totally 6 cables constitute.
Owing between field controller of the present utility model and valve control circuit plate, be provided with at least by serial and sending bus, parallel receive bus, testbus and corresponding ground wire totally 6 combination cables that cable constitutes, so not only the mechanical strength that cable connects between each module is improved, and transmission data stabilization, the influence of the form that do not connected up, antijamming capability is stronger, particularly when broken string takes place, the connection status of circuit between each module can be controlled by testbus, thereby the place of breaking can be found fast.Carry out scene seeking even enter the farmland, because known fault point position is with strong points, therefore can not cause the farmland extensive damage, maintenance cost is low, is easy to promote.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the syndeton schematic diagram of the utility model embodiment 1;
Fig. 2 is the syndeton schematic diagram of the utility model embodiment 2;
Fig. 3 is the electrical block diagram of the utility model main station controller;
Fig. 4 is the electrical block diagram of the utility model field controller.
Embodiment
A kind of drip irrigation control system, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, comprise main station controller, field controller, valve control circuit plate and magnetic valve, main station controller be finish that the PC control order sends and with each field controller communication, realize that order is assigned and the intermediate link of data acquisition.
Main station controller is made up of single-chip microcomputer, power supply, static memory, watchdog circuit, time-of-day clock circuit, communication commutation circuit and communication interface.A plurality of power supplys are being set, for different components and parts provide different power supply to improve antijamming capability in main station controller.Field controller is directly controlled the switching of big each electromagnetic valve of Tanaka, has the function that receives the main station controller instruction and feed back various running parameters to main station controller.Field controller is made up of single-chip microcomputer, power supply, address dial, keyboard interface, control circuit, sample circuit, communicating circuit etc.For satisfying the voltage request of different components and parts, the power supply of field controller adopts the modular Switching Power Supply.
In order to improve the communication reliability between each module of the utility model and to reduce rate of breakdown, reduce maintenance cost, should be at least between field controller and valve control circuit plate, be connected combination cable 2 be set, said combination cable 2 by serial send bus, parallel receive bus, testbus and corresponding ground wire totally 6 cables constitute.As shown in Figure 3, Figure 4, in order to improve interference free performance, reduce the influence of distribution capacity and correlated noise, guarantee that stable signal transmission is reliable, the microcontroller serial port end of installing in main station controller and field controller is connecting electric current loop communicating circuit 3 respectively.As shown in Figure 2, for the smaller farmland of irrigated area, linking to each other by said combination cable 2 between main station controller and the field controller gets final product.Also can link to each other between the valve control circuit plate by said combination cable 2.As shown in Figure 1, for the bigger farmland of irrigated area, consider on-the-spot distance, the wiring difficulty big, cost is high, usually use data radio station 1 transmitting control data and Monitoring Data between main station controller and field controller, promptly on main station controller, connecting data radio station 1 by the RS232/RS485 cable, corresponding, on field controller, also be connected with data radio station 1, so both satisfy the requirement of transfer of data, accelerated construction speed again.
In order to improve automatic control level, main station controller is connecting control calculator 4 by the RS232/RS485 interface.
