Introduce the sensor method for customizing below.
At present, the risks and assumptions relevant with agricultural production is more, for example sunshine time, net radiation, wind speed, wind direction, temperature, humidity, soil moisture, quantity of precipitation etc., system are wanted to customize type of sensor adaptively, and can support the product sensor model of many producers.The signal output signal of sensor mainly contains three classes: impulse type, current mode and voltage-type, and support the sensor of pulse type signal output to have: precipitation sensor, air velocity transducer etc.; Support the sensor of voltage-type signal output to have: sunshine time sensor, net radiation sensor, wind speed wind direction sensor, Temperature Humidity Sensor, soil moisture sensor etc.; Support the sensor of current mode signal output to have: wind speed wind direction sensor, Temperature Humidity Sensor, soil moisture sensor etc.
The present invention proposes a kind of universal data collection method, cooperation by software and hardware, link mutually by data center and collecting device, make collecting device can connect production, the various sensors unlike signal way of output, dissimilar of different manufacturers, can customize neatly according to kind, growth phase, the planting area of crops.
As shown in Figure 2, the maximum 8 circuit-switched data acquisition interface of this equipment support, each interface all can customize and connect electric current, voltage and impulse type sensor.The electric current of standard is input as 4-20mA, and the voltage of standard is input as 0-3.3V.In order on electric interfaces, to adapt to the mode signal output of different sensors, control by 8 way switch.For the sensor of current mode and impulse type, on-off circuit be placed UNICOM's state, through variable resistor it is become the voltage signal of 0-3.3v.Sensor for voltage-type places off-state with on-off circuit, and signal is connected to the A/D port by holding circuit, carries out the collection of data.
Want to customize sensor type adaptively, important problem is how collecting device to discern is the sensor of which kind of type.
Because collecting device is a kind of embedded device, and require Installation and Debugging simple as much as possible, easy-to-use, therefore will think to the configuration of sensor and move on in data center's software systems, when carrying out facility registration, carry out the registration of its each entrained sensor, comprise Register Sensor type, interface type, frequency acquisition, report information such as frequency, disaster threshold value, sensor states.Behind device start, collecting device is handed down to above-mentioned information in data center.
Collecting device carries out initialization to each A/D acquisition interface, and carries out data acquisition by assigned frequency after receiving above-mentioned message.For amperometric sensor, because it has converted voltage signal to by variable resistor and support circuit thereof, therefore can take same strategy to handle with voltage sensor, the signal of gathering is 0 to 1023 discrete data, and the implication of data is changed by type of sensor by data center.Need interrupt process to carry out the seizure of pulse signal for the impulse type sensor.Also have two types of needs to handle for the pulse signal after gathering, a kind of type that adds up is as rainfall; Another kind is a frequency type, as wind speed.Processing for the type sensor that adds up is fairly simple, the accumulated value of a recording impulse, after reporting with its zero clearing; For the sensor of frequency type, at first in a collection period, carry out accumulated counts, after collection period finishes,, obtain the average frequency information of pulse again divided by the time interval of its frequency acquisition.
Introduce below and how to customize crop growth model and crops hazard model.
Disaster alarm is the critical function that high applicability agricultural product production risk factor data is gathered.System can be the last lower threshold value of every kind of sensor customization early warning, when Monitoring Data surpasses threshold range, this sensor produces a chance alarm announcement automatically and reports data center, and this sensor changes over to and meets alert state simultaneously, and frequency acquisition and data report frequency all can strengthen until alert and remove.
The growth of crops is a very long process, and this process can be divided into a plurality of stages.The crop difference, the stage of division is also different, for example winter wheat can be divided into from planting maturation: emerge, three leaves, tiller, survive the winter, turn green, stand up, jointing, booting, ear, bloom, 12 stages such as grouting, maturity stage.In each stage, the principal risk factor that influences plant growth is different; Simultaneously with a kind of crop because the planting area difference, each place date in stage, lasting time length also can be different.Therefore, be according to planting area, the kind of plantation crops, the last lower threshold value that residing growth and development stage is set each sensor in real time.
Fig. 3 is the collecting device initiation message sequential chart of agricultural product production risk factor data acquisition system of the present invention, and as we can see from the figure, native system is supported the setting and the change of the threshold value of each sensor.System is in implementing deployment, kind according to crop is divided growth phase, set up the hazard model of every kind of risks and assumptions again according to the historical information of this zone (granularity in zone refers generally to the county) past three year environment, and then calculate the threshold curve up and down of every kind of risks and assumptions, just can set the last lower threshold value of every kind of risks and assumptions, every day according to this threshold curve.Data center every day, the threshold setting with each sensor was handed down to collecting device.
Introduce the data acquisition scheme of native system below.
Data center constitutes a data acquisition system with collecting device, and data center also carries out image data and receives and management work when finishing equipment and carrying the management of sensors task.
The equipment support reports mode for three kinds, is respectively periodic report, meets alert report and instruction reports.Periodic report is according to the agricultural product condition of production, sets fixing report cycle, and collecting device periodically reports Monitoring Data; Meeting alert reporting is according to set strategy, and after Monitoring Data broke through setting numerical value, equipment initiatively reported Monitoring Data information, to support early warning work; It is that data center issues a data query instruction that instruction reports, after collecting device is received instruction, and real-time report Monitoring Data information.Equipment can be according to the threshold value that sets in advance automatically at periodic report with meet alert reporting between pattern and change, meet under the general situation and alertly report the frequency acquisition of pattern and report frequency big than under the periodic report pattern.The frequency acquisition of each sensor that equipment carries and report frequency also can to change according to the growth phase of crop.
Introduce the problem that transmission of messages faces below.
Reporting of the management of collecting device, data all needs to finish by the information interaction between data center and the collecting device, carries out the transmission of message between them by the GSM network.
First problem that faces is a transmission cost.Owing to also do not have any wide-area deployment under the 3G network lowered in field environment, therefore still pass through the 2G network in the transmission of message.The expense of transmission is directly proportional with the transmission quantity of data.
Another key issue of data acquisition is the data security problem.This is mainly concerned with: 1) junk data bombs problem, and data center wants to filter out the reported data of non-Authentication Client equipment; 2) data falsification center instruction issue, the configuration of collecting device, initialization, acquisition tasks all issue by data center's instruction and finish, and collecting device is wanted to discern legal data center; 3) data confidentiality problem, the data of collection will be transmitted with the form of ciphertext in the process of transmission, prevent that data from being monitored and distort.Preceding two problems can solve by Handshake Protocol.
Simultaneously because above-mentioned work will be finished, because collecting device is a kind of embedded device, its processor processing speed and storage space are all limited, need therefore that agreement is simple as much as possible, light weight on collecting device.
Existing communication protocol can not satisfy above-mentioned reporting functions and data compression function to equipment and management of sensors function, data, therefore the present invention proposes a kind of new communication protocol.
Introduce protocol model below.
Similar with the TCP/IP model to OSI, agreement adopts hierarchical model, and bottom-up is respectively Physical layer, network layer, transport layer and application layer.Wherein transport layer can be supported traditional TCP/IP model, and based on the short message service SMS of GSM network and GPRS packet service etc.Agreement is defined within the application layer, and its message can be by the application program establishment or the parsing of protocol compliant standard arbitrarily.
Table 1 protocol hierarchy table
The block diagram of agricultural product risks and assumptions data acquisition system (DAS) as shown in Figure 4.Wherein, need communication between data acquisition management system and the collecting device, this will be by the collection communication Platform Implementation.In the collection communication platform, acquisition protocols is realized by the acquisition protocols framework.System is communication specification based on the GSM network with the acquisition protocols, uses SMS and GRPS service transmission information between management system and collecting device.
The present invention proposes and has realized that a kind of high applicability agricultural product production risk factor data acquisition system, this data acquisition system (DAS) relate to by data acquisition equipment and control data corporation cooperation to finish the customization of sensor and the customization of early warning hazard model.Wherein, maximum portability No. 8 sensors of agricultural product production risk factor data collecting device, the sensor output signal interface can be any in impulse type, voltage-type and the current mode, this equipment is undertaken alternately by GSM network and data center, collecting device adopts external 220v AC power to power, after external power interruption, enable standby 6v rechargeable battery power supply, sustainable 48 hours of powered battery.Equipment is supported periodic report, chance police reports and instruction reports three kinds of data to report mode, supports the real-time setting of each sensor threshold value.The dependent thresholds of crop growth model and crops hazard model can be by data center by both fixed cycle settings.The minimum particle size of threshold setting is the sky in hazard model.Communicate by the GSM network between data acquisition equipment and the control data corporation.The communications framework that the present invention proposes encapsulates and operates acquisition protocols exactly, and extended method flexibly is provided enough, not only supports the communication of SMS-Based, can be based on communicating by letter of GRPS and 3G the basis is provided.
