Embodiment
The utility model greenhouse computer control system is made of more than one discrete control module; The output of each discrete control module greenhouse controller connects the input port of central computer altogether by communication bus, implements control by central computer.
As shown in Figure 1, discrete control module structure of the utility model comprises:
One places the sensor 1 of chamber, greenhouse inside/outside;
One input acquisition module unit 2;
One control core component CPU element 4;
One output acquisition module unit 3;
The output of sensor 1 connects the input of input acquisition module 2 (model is EM231) by signal transmssion line, core component CPU4 (model is S7-200) is controlled in outputing signal to of this input acquisition module, through computing, the analysis of control core component CPU, give the J1 of executing agency (motor relay of window is backed down in control), J5 (control external sunshade motor relay), the audible-visual annunciator 5 in control greenhouse by output acquisition module 3 (model is EM222) output control signal.
In the present embodiment, above-mentioned sensor 1 for the executing agency in the greenhouse that places indoor Temperature Humidity Sensor (sensor model number is VAISALA) and adopt for backing down window motor, external sunshade motor, audible-visual annunciator.
For cooperating to a plurality of parametric measurements, monitoring, also can use sensors such as temperature that outdoor meteorological station is provided with, illumination, rainfall, wind direction, wind speed simultaneously, be input among the control core component CPU4 simultaneously by each sensor signal outside the outdoor meteorological station detection module sensing chamber, and by signal transmssion line.
Above-mentioned greenhouse executing agency also can be the external sunshade motor that is used to drive sunshade, the work drive motor that drives wet curtain window, ventilation all or part combination with blower fan;
Above-mentioned one group of all or part combination of sensing device that places indoor, the outdoor sensor in greenhouse also to can be to be used to the temperature/humidity sensor of surveying temperature/humidity and illumination, rainfall, wind direction, wind speed.
The general control system in the utility model greenhouse is realized with relevant software program by central computer (Intel Pentium 4 256M RDRAMPC machines), 1 host computer and a plurality of down discrete control module are realized the master-slave mode communication, a plurality of greenhouses are monitored, managed and control, the adjustment and the expansion of system can be according to circumstances carried out in central computer and employing RS485 bus connection between the discrete control module down at any time.Each discrete control module is to temperature, humidity, illumination and wind speed, wind direction, rainfall, the meteorological environment factors such as illumination are monitored and greenhouse facilities are controlled, its two parts function is as follows: 1, PC is configured whole system, and the control parameter of following discrete control module is set, and reads the data of measurement, storage shows operations such as printing; 2, discrete control module (each greenhouse of down discrete control module control) has data acquisition and control function down, can be independent of PC work.If PC is start not, following discrete control module also can carry out data acquisition and control automatically, and test data is deposited in the inner mass storage, it is imported in the PC database after waiting the PC start again.
Its operation principle and process: at first gather average indoor temperature, humidity, and be sent to greenhouse controller (being CPU element 4) by signal transmssion line by sensor and input acquisition module; Also be input to the greenhouse controller simultaneously by each sensor signal (as temperature, illumination, rainfall, wind direction, wind speed etc.) outside the outdoor meteorological station detection module sensing chamber, and by signal transmssion line; The greenhouse controller carries out computing, analysis by software program to each data of acquisition module collection again, thereby determine whether to reach each equipment of operation (as executing agencies such as external sunshade, wet curtain windows), so that the temp. and humidity in the control greenhouse etc. make it to reach the growing environment requirement of crop.
Can import the condition (as temperature, humidity, illuminance etc.) that each equipment moves by computer operating system software, both the unlocking condition to each equipment carried out independent control.Simultaneously, the operation conditions that on the computer software screen, shows each equipment with the form of animation.Except that inferior, computer operating system software also has each software kit such as data query, greenhouse warning.
