Hardware used in the present invention is specifically described as follows:
The microprocessor of the present invention uses S3C6410 (ARM11) embedded microprocessor that Samsung company is up-to-date, and specifically used hardware platform UP-CUPIOT-6410-II type development board is S3C6410 (ARM11) embedded microprocessor up-to-date based on Samsung company.S3C6410X is the risc microcontroller of a 16/32, has the fine qualities such as low cost, low-power consumption, high-performance, it is adaptable to mobile phone and be widely applied exploitation.Thering is provided superior performance to the communication service of 2G and 3G, S3C6410X uses 64/32 inside bus structure, its internal bus be by AXI, AHB and APB tri-partial bus constitute.S3C6410X include many hardware adaptor, 4 passage UART interface, 32 passage DMA, 5 passage 32 bit timing devices and PWM output, general purpose I/O port, I2S interface, EBI, I2C EBI, usb host, hi-speed USB interface OTG equipment (transmission speed of 480Mbps), 3 passage SD/MMC remember console controllers and PLL clock generator.ARM subsystem be based on ARM1176JZF-S be core.It includesIndependent16KB instruction and 16KB data high-speed cache, 16KB instruction and 16KB data.
Each switch that controls of the present invention all uses relay control switch: the relay used uses one-level amplifying circuit; input signal is amplified; and then drive relay to trigger, control the parts of appliance such as light compensating lamp, greenhouse air conditioner, illumination protecting film, spray drop filling；CircuitFigure such as figure 5Shown in.
When Temperature Humidity Sensor DHT11 measured temperature reaches the low temperature that parameter is preset, greenhouse can automatically start heating rod and heat up greenhouse, and when greenhouse reaches the high temperature that parameter is preset, greenhouse can automatically start air conditioner, lower the temperature greenhouse.
Greenhouse degree sensor DHT11 brief introduction:
The communication of DHT11 can complete (steps of the peripheral hardware such as data of microcomputer reads DHT11) by following several steps.
Step one:
After DHT11 powers on (DHT11 after powering on 1s to be waited can not send any instruction during this period to cross labile state), test environment humiture data, and recording data, the DATA line of DHT11 is drawn high by pull-up resistor and is always maintained at high level simultaneously；Now the DATA pin of DHT11 is in input state, moment detection external signal.
Step 2:
The I/O of microprocessor is set to output output low level simultaneously, and the low level retention time can not be less than 18ms, and then the I/O of microprocessor is set to input state, due to pull-up resistor, the I/O of the microprocessor i.e. DATA line of DHT11 uprises the most therewith, waits that DHT11 makes recall signal
Step 3:
The DATA pin of DHT11 detects when external signal has low level, wait that external signal low level terminates, after delay, the DATA pin of DHT11 is in output state, export the low level of 80 microseconds as answer signal, and then the high level notice peripheral hardware exporting 80 microseconds prepares to receive data, the I/O of microprocessor is now in input state, after detecting that I/O has low level (DHT11 back-signalling), waits the data receiver after the high level of 80 microseconds.
Step 4:
40 bit data are exported by the DATA pin of DHT11, microprocessor receives 40 bit data according to the change of I/O level, the form of bit data " 0 " is: the low level of 50 microseconds and the high level of 26-28 microsecond, and the low level that form is 50 microseconds of bit data " 1 " adds the high level of 70 microseconds.
Light sensor use photoconductive resistance:
Photosensitive circuit is placed on the top in greenhouse, and it is used for detecting the intensity of illumination in the external world.When intensity of illumination is sufficiently strong, greenhouse will be in open curtain state, i.e. allow the light in the external world enter in greenhouse.When extraneous intensity of illumination is strong not, greenhouse will automatically put down illumination isolation protection film and opens light compensating lamp plant carries out light filling process, and illumination isolation protection film can make the luminous energy in greenhouse reduce to run off.
Video camera:
Video camera is by being connected by serial ports between development board with PC or passing through wireless connections.
The present invention uses goahead server that with greenhouse information, webpage is produced interactive function, and goAhead is the embedded web server of increasing income that a function is more complete, and goAhead supports asp, embedded, javascript, CGI and static page html.Fast response time, per second processes the request more than 50.If not comprising SSI, require nothing more than the internal memory of 60K；Comprise SSI, it is desirable to 500K internal memory.Web page can exist in ROM or file system.Support several operation systems, including vxWorks, LINUX, Windows, WinCE etc..Use Apache Server with greenhouse information, webpage can also be produced interactive function, but use apache server requirement configuration surroundings higher, and volume is relatively big, is adapted to the webpage making that larger pageview is huge, so finally selecting gohead server is the server of the present invention.
The realization of Web server: Web server is the key equipment of network application, mutual by the information using Web browser can complete between the two.Web server is formed by using the language such as HTML HTML, JavaScriptFigureWen Bingmao information page, Web browser is a kind of common device of networked desktop, can provide and communicate with remote equipment and the abundant function of display data, providing the user user interface based on http hypertext transfer protocol, Web browser accesses the HTML on remote web-server by Internet.In the client computer/browser working environment of Web, Web browser plays control action, and it, by obtaining the document on Web server with a URL, explains this HTML, and by document content with the expressive ability licensed by user environment, show to greatest extent.Web server provides the means from equipment derived information, is provided the means of display dynamic data by CGI (CGI).Figure 2It it is Web server operation principle.
The realization of camera collection: its operation principle is that scenery projects in image sensor surface by the optical imagery that camera lens generates, then turn to the signal of telecommunication, data image signal is become after A/D changes, it is then sent through processed in digital signal processing chip, then is transferred in the processor on development board process by USB interface.Figure 3It it is photographic head operation principleFigure。
The realization of wireless network card: the design specifically uses USB wireless network card as the equipment of transmission data, broadband has extremely significantly advantage, speed can reach 11～108Mbps, and effectively transmission range is the biggest, video data can be transmitted glibly, it is achieved that the smooth playing of video to host.
Utilize wireless network card can realize the video collected to realize on mobile phone.By collecting the video information in greenhouse by the way of webpage, video is shown on webpage.
The realization of GSM: the very first time can being apparent from by 3G network user is known, on-the-spot real time information, concrete framework is as follows, whereinFigure 4It it is GSM frameworkFigure；The gsm module used is the GTM900B module of Huawei.GTM900B is nearly product newly gone out for 2 years, is outstanding in terms of signal quality, disposal ability.Through reality test, gsm module stability, reliability, economy are high.
For the gsm module of seedling booth, use wireless network GSM node, in the way of short message is sent out, it is achieved householder and the docking of seedling booth.More quick, be accurately obtained the instant messages in greenhouse, use the mode of wireless network, it is to avoid the complexity of maintenance simultaneously.
Gsm module is made up of three parts, is respectively as follows: collection information, controls main frame, client terminal.This frameFigureSpecifically understand workflow.Information gathering in greenhouse, after the treated device of sensor signal is analyzed, is given to gsm module by signal, gsm module uses GSM network, send an SMS to householder's mobile phone, inform the instant messages in householder's seedling booth.
