Embodiment
As Fig. 2～Figure 3 shows that the utility model silo grain complex closes the structure principle chart of an embodiment of detection system, as seen from the figure, this system comprises silo data acquisition unit, radio extension and portable control center.The silo data acquisition unit comprises temperature sensor, humidity sensor and the data processor that each measurement terminals is provided with, and sensor is arranged in the silo, is responsible for the grain feelings information of detected temperatures and humidity; Data processor can be arranged in the grain heap, also can be arranged on grain out-pile face, directly links to each other the signal of the autobiography sensor of collecting with temperature, humidity sensor cable; Passing through wireless communication module after treatment---the CC1100 wireless data transmission module sends to radio extension; Humiture data after radio extension is handled it are sent to the portable control center by the radio station.Adopt AVR single-chip microcomputer, ARM7 and ARM10 kernel processor chip in the present embodiment respectively, have advantages such as low in energy consumption, that processing speed fast, the memory node data are many as measurement terminals silo data acquisition unit, radio extension and portable control center.
The measurement terminals of silo data acquisition unit arranges that according to the distribution standard of sensor each end points identifies with ID in the storehouse, and whole silo forms a distributed wireless sensor network.The AVR chip microcontroller of wireless measurement end points super low-power consumption, use a joint 3.6V lithium battery, adopt and boost and Voltage stabilizing module, make battery operated voltage range broad, can be stabilized to 3.3V from 0.8V～3.6V, can fully use up all electric energy of battery; In addition, adopt under-stream period to match with rest period on communication mechanism, main frame Remote Wake Up function has realized the purpose of extremely low power dissipation, and through calculating and test-run a machine, one saves new battery can make the continuous working of wireless measurement end points about 4 years.
The wireless transmission method that the utility model relates to has adopted current advanced person's wireless sensor network technology.Each wireless measurement end points has unique encoding, it is ID number, built-in wireless transmitter module, the data that transmitter module is gathered sensor by instruction are inquired about, and measured data carry out behind the compressed encoding sending with the signal that is converted into a certain frequency for ID number jointly.Based on the wireless data transmission module system of CC1100 chip, to have realized detecting the reliable communication between extension set outside end points and the storehouse in the storehouse, communication distance is above 300 meters.Adopt reliable wireless interference protection measure: used frequency range difference in the different storehouses, in case the phase mutual interference.The silo spacing is generally nearer, all adopt radio communication in each storehouse, radio communication phase mutual interference in each storehouse, make and near 433MHz, divide 80 wave bands, use same wave band outside the storehouse, make like this and avoided the phase mutual interference between each storehouse, solved simultaneously in the storehouse with the storehouse outside the mutual interference mutually of radio communication, make system communication mechanism reliable and stable.
After radio extension receives data, just obtain data and ID number behind the coding that decompresses.A radio extension can receive the data that a plurality of wireless measurement end points are sent simultaneously, be that each warehouse is provided with a radio extension, arrange many cable for measuring temperature by certain mounting means, the wireless measurement end points is installed in the top of cable for measuring temperature, arranges measurement point as required on cable for measuring temperature.Launch data after the wireless measurement end points inquiry humiture information, radio extension is transported to the portable control center after receiving and resolving, for next step grain condition analysis and Control work are prepared.
Radio extension arrives the portable control center by data radio station with data delivery, be that radio extension links to each other with data radio station, data radio station by radio communication with data transfer to control center, this transmission mode make total system realize in the storehouse and the storehouse outside wireless connections, communication distance is above 3 kilometers.
Be illustrated in figure 4 as the circuit module structure principle chart of the utility model silo data acquisition unit, the signal output part control linkage of the signal input part of the single-chip microcomputer of silo data acquisition unit and temperature sensor and humidity sensor, the control output end is connected with radio extension by wireless transport module, setting boost voltage stabilizing and low pressure detection module have increased stability, reliability and the working time of system's operation.Single-chip microcomputer is handled the humiture data of other position in the grain that the collects heap or in the silo, is transferred to wireless data transmission module through the serial communication line, wireless data transmission module the humiture data are carried out coded modulation after antenna transmission to radio extension.
Be illustrated in figure 5 as the circuit module structure principle chart of the utility model radio extension, with ARM7 is kernel processor chip, adopt measures such as photoelectricity isolation, anti-thunder tube, increased system thunder defending and hit performance, can expand some peripherals such as connecting LCD, keyboard, toggle switch and work indication.Radio extension receives the signal that the wireless measurement end points is sent by antenna, is transferred to ARM7 by the serial communication line behind the wireless data transmission module demodulating and decoding, and ARM7 is sent to control center with the humiture data after it is handled.
Portable control center is made of arm processor, storer, LCD MODULE and wireless communication module.Arm processor has advantages such as low-power consumption, high-performance and peripheral interface enrich, and can transplant embedded real-time operating system, realizes multi-task scheduling, analyzes, handles and demonstration grain feelings information.
The portable control center receives the data that the data communication layer is transmitted, and the humiture data is carried out the location of silo and point for measuring temperature according to source extension address, source wireless measurement end-point addresses; Giving data processing module with data handles, stores.
Except the grain feelings detected, the portable control center also had grain condition analysis and functions such as networking, printing.
The utility model is used in the silo detection to the grain feelings with wireless communication technology, wired mode that data in the storehouse move by original use stube cable changes wireless mode into, promptly realize by the mutual transmission between the wireless data transmission module, and adopted the multiband technology, therefore wireless transmission has improved the reliability and the maintainability of system, has also reduced the spoilage of labor strength and cable simultaneously.
