Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
The hardware block diagram of a kind of portable greenhouse environmental parameter harvester of the present invention is as shown in Figure 1.Comprise microprocessor and serial ports expansion chip, data storage module, keyboard, liquid crystal display, time module, test amplifying circuit, communication interface and voltage transformation module; Communication interface, keyboard and LCD MODULE through and the serial ports expansion chip link to each other with microprocessor; The input end of microprocessor links to each other with various required sensors through the test amplifying circuit; Data storage module directly is connected on the microprocessor through the SPI communication that microprocessor carries, and time module has microprocessor I/O mouth directly to drive, and microprocessor increases I/O mouth and serial ports number respectively through parallel port extended chip (8255a) and serial ports expansion chip GM8123; Wherein, Keyboard and liquid crystal display are connected on the 8255a chip, and after two-way converted 232 level in 3 road serial ports of GM8123 expansion, the one tunnel was used for communicating by letter with PC; A sensor communication that is used for 232 level, the serial ports of remaining one road Transistor-Transistor Logic level only with TTL serial ports sensor communication.
Microprocessor spce061A uses 10 high-speed a/d translation functions of self integrated octuple, and utilization wherein 6 the tunnel converts analog sensed signal (voltage, electric current) to digital signal and handles; Draw two I/O mouth lines that do not use this function and be used to connect sensor with I2C or SPI digital communication signal.Wherein, 6 road A/D conversion I/O mouth line connects test amplifying circuit signal output part.In the test amplifying circuit, the mV magnitude voltage signals zooms into the V magnitude voltage signals through filtering and second amplifying circuit, but amplifier is selected the operational amplifier LM358 of binary channels input single power supply, low-power consumption for use; MA level current signal connects a precision resistance between delivery outlet and ground, making it output also is the V magnitude voltage signals.The test amplifying circuit is provided with the signal voltage dividing potential drop adjustable resistance after the amplification, so that regulate the single channel measurement parameter in the later stage use.Sensor with analog quantity output signals inserts the test amplifying circuit through communication interface.
Consider the cost of apparatus of the present invention and be not all the sensors that each user can use this device support in users use; And prices are rather stiff for a lot of sensors (needing about 980.0 yuan like the carbon dioxide digital sensor), so all the sensors of apparatus of the present invention all adopts flexible circumscribed.On Design of System Software, set the sensor drive program that various this system supported.Only need the user to be connected on the corresponding interface during use and select corresponding sensor drive or range (need regulate suitable range for analog signal sensors) can drive this kind sensor.But the notebook data collector also provide a pressure regulation power interface (0 ~ 24V), the use of convenient various analog sensors.The use of the integrated as far as possible more multiple digital of this device sensor like Temperature Humidity Sensor 18b20 and DHT21, all is I2C communications protocol, when you insert the corresponding port of portable greenhouse data acquisition unit, in respective selection, chooses corresponding driving to get final product again.Apparatus of the present invention are supported the upgrading of driver.
As a kind of intelligent measuring device, except that require the interface visual strong, stable, operation is simple and reliable for it, using flexibly, conveniently is apparatus of the present invention one big advantages.The function of certain button of keyboard is launched round the liquid crystal display prompting, and 16 buttons are distributed in around the liquid crystal display.As shown in Figure 2, be the measurement channel selecting interface of a kind of handheld portable greenhouse of the present invention parameter acquisition device.Wherein the figure on Fig. 2 left side is the selection interface of inserting the analog sensor signalling channel, and the figure on the right is the selection interface of inserting the digital sensors signalling channel.When a certain analog sensor inserts a certain passage, select this passage through the prompting button on LCDs next door, and can get into measurement channel parameters value modification interface as shown in Figure 3.The screen periphery demonstrates following 16 buttons in this interface function separately.Revise range according to the prompting operation on the liquid crystal display, make it be fit to this sensor; Also need revise the analog signals of this sensor and the relation of the parameter of surveying, i.e. multiplying power simultaneously.Range is selected the whether suitable acquisition precision that determines this tunnels analogy amount for use, and the reference voltage when range is revised is selected from the 5V voltage of apparatus of the present invention self.Each passage can be worked simultaneously, and range etc. all can be different.In like manner, when digital channel inserts digital sensor (sensor voltage and communication level must select to), only need this passage of selection and set this sensor for driver get final product.
