Accompanying drawing 2 is the workflow schematic diagram of a kind of distributed accelerometer data harvester of the present invention.
Accompanying drawing 3 is the hardware schematic of a kind of distributed accelerometer data harvester of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment that the present invention is provided is elaborated.
With reference to Fig. 1, a kind of distributed accelerometer data harvester of the present invention, including control module, modular converter, deposit
Storage module, wireless module, control module are connected with modular converter, memory module, wireless module respectively, and control module is that ARM is micro-
Controller, modular converter is modulus conversion chip, and memory module is flash card or hard disk, and wireless module is wireless network sensing
Device, is the one kind in bluetooth sensor, WIFI sensors, radio transceiver sensor or ZigBee sensors.
With reference to Fig. 2, the workflow of a kind of distributed accelerometer data harvester of the present invention is：Accelerometer is gathered
Data Jing charge amplifier amplification after transmit to data acquisition unit；Data are carried out modulus by the modular converter in data acquisition unit
Conversion, and by the data transfer after conversion to control module；After control module is processed to data, store to memory module,
And while be published in wireless network by wireless module；Equipment receiving data in same wireless network；End of transmission
Afterwards, memory module is taken out, and the data in memory module is synchronized into integration.
Preferably, with reference to Fig. 3, a kind of distributed accelerometer data harvester of the present invention, its control module is
STM32F103 microprocessors, modular converter are ADS1256 modulus conversion chips, and memory module is SD card, and wireless module is
ZigBee sensors, it is as follows which is wirelessly transferred experiment：
Experiment one：Direct-connected two-forty test, accelerometer group stands and directly exports indoors, for detecting STM32F103
The data-handling capacity of microprocessor；
Experiment two：Measurement of near distance, is calculated as output source in roof placement 3-axis acceleration, and STM32F103 microprocessors are read
Carried out data transmission by ZigBee sensors after fetching data, it is dew of the receiving terminal range transmission end less than 5 meters to receive and dispatch environment
Its roof, for the laser propagation effect under test signal good condition；
Experiment three：Wireless Mesh netword is disposed in same Zhuan Lou buildings, the data positioned at roof that script cannot be interconnected are adopted
Storage is connected with the receiving device in room, tests the data transfer effect after routing node turns, nothing in Mesh nets
About 85 meters of thread path total length；
Experiment four：Distance Test, under spacious situation of the distance for 400 meters, two roofs carry out transmitting-receiving test, are used for
Test Long-range Data Transmission effect.
Three groups of message transmission rates of each experiment test, every group of data transmission bauds are tested three times, and are averaged；Every time
Experiment test removes 2 second datas end to end, and when preventing equipment from just starting, caused by unstable networks, transfer rate declines.
1. data transfer of table tests each item data
From experimental data as can be seen that in usual cases, when data acquisition unit carries out data processing, transmission, will not
There is loss of data；When being wirelessly transferred, data have certain probability and go out active, and its reason is mainly wireless network
2.4GHz frequency ranges and ZigBee sensors in integrated RF components meet interference.Although having when real-time radio is transmitted certain
Probability causes loss of data, but SD card is also included in a kind of data acquisition unit of the present invention, for staff between not
Disconnected data carry out reclaiming, contrast, analyze.Real-time radio transmission is cooperated with SD card, it is ensured that real-time Transmission efficiency and data
Integrity.
The advantage of a kind of distributed accelerometer data harvester of the present invention is electric charge output type acceleration of can plugging into
Meter or piezoelectricity output type accelerometer；Cost is relatively low, reduces monitoring enforcement difficulty；Can be according to accelerometer quantity, in data
The modular converter of respective numbers is set in harvester；By data real time parsing, compress, store and be dealt into wireless network；Can
Guarantee the integrity of data transfer, improve work efficiency.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, on the premise of without departing from the inventive method, can also make some improvement and supplement, and these improve and supplement also should be regarded as
Protection scope of the present invention.
