Description
Technical field
The utility model relates to a kind of humiture collection terminal, especially super low-power consumption humiture wireless acquisition terminal.
Background technology
Temperature-humidity monitoring has a wide range of applications in fields such as Industry Control, agricultural management, warehouse storage, historical relic's protections, and the humiture network monitor equipment of research low-power consumption, low cost, high reliability is extremely important.The humiture network sensor of application adopts ZigBee technology mostly at present, although the ZigBee technology power consumption is lower, but its transfer rate is low, the WSN built seals, can not be directly integrated with Internet/Intranet, need the support of gateway, by comparison, the WiFi technology has that transfer rate is high, wide coverage, networking cost are low, with the advantages such as the Internet network seamless is connected.
Summary of the invention
In view of above reason, the utility model provides a kind of super low-power consumption humiture wireless acquisition terminal, adopting the super low-power consumption chip GS1010 of integrated WiFi function is core, by reducing number of communications, reduce sensor data acquisition, the power consumption while processing, make most time of node in dormant state, reach the purpose that extends sensor life-time.
The utility model solves the technical scheme that its technical matters adopts: a kind of super low-power consumption humiture wireless acquisition terminal, comprise humiture data acquisition module, main control module, usb interface module, power module, filtering transceiver module, it is characterized in that, main control module is connected with humiture data acquisition module, usb interface module, power module, filtering transceiver module respectively, and power module also is connected with humiture data acquisition module, usb interface module respectively.Main control module is after unlatching humiture data acquisition module carries out data acquisition, immediately data are not sent, but at first with historical data before, compare, if (difference of temperature data is within 0.5 ℃ in certain scope for the difference of the temperature data collected for twice, the difference of humidity data is within 1.0%RH), and terminal just thinks that current extraneous state does not change, need not be to Surveillance center's wirelessly transmitting data, but directly enter low power consumpting state, after exceeding certain limit, main control module is sent to Surveillance center by data in the mode of udp protocol by inner radio-frequency (RF) transceiver and filtering transceiver module.
The beneficial effects of the utility model are that working stability, reach the monitoring of low-power consumption humiture data wireless, has higher practicality.
The accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
In Fig. 1, a kind of super low-power consumption humiture wireless acquisition terminal, comprise humiture data acquisition module 1, main control module 2, usb interface module 3, power module 4, filtering transceiver module 5, it is characterized in that, main control module 2 is connected with humiture data acquisition module 1, usb interface module 3, power module 4, filtering transceiver module 5 respectively, and power module 4 also is connected with humiture data acquisition module 1, usb interface module 3 respectively.Main control module 2 is after unlatching humiture data acquisition module 1 carries out data acquisition, immediately data are not sent, but at first with historical data before, compare, if (difference of temperature data is within 0.5 ℃ in certain scope for the difference of the temperature data collected for twice, the difference of humidity data is within 1.0%RH), and terminal just thinks that current extraneous state does not change, need not be to Surveillance center's wirelessly transmitting data, but directly enter low power consumpting state, after exceeding certain limit, main control module is sent to Surveillance center by data in the mode of udp protocol by inner radio-frequency (RF) transceiver and filtering transceiver module 5.
The SHT15 single-chip digital humiture integrated sensor that humiture data acquisition module 1 adopts Switzerland Sensifion company to release, this product low-power consumption, the characteristics that response is fast, volume is little, SHT15 powers on or data acquisition and communication work can be advanced people's park mode after completing automatically in system, its sleep current is only 0.3 A, temperature and humidity transition response shortest time is respectively 5s and 8s, by the two-wire system digital interface, with main control module 2, is connected.The super low-power consumption SoC chip GS1010 based on IEEE 802.11b/g that main control module 2 adopts GainSpan company to release, quiescent current is only 5uA, this chip adopts two ARM7 processor structures, by the peripheral hardwares such as 384 KB Flash, 192 KB SRAM, 802.11 MAC/PHY and RF transceiver and IC, SPI, ADC all design in the single-chip of a QFN encapsulation, reduce the complicacy of system power dissipation and application design, realized the microminiaturization of humiture wireless acquisition terminal and integrated.Usb interface module 3 adopts the usb communication interface can save the PCB space, dwindle terminal volume, this interface both can be used for wired download and the debugging of program, also can do the man-machine interaction of end message output, and, in the situation that the terminal normal operation is to adopt wireless mode to carry out Data Collection and network node control, therefore is designed with special power switch it is closed.Power module 4 adopts the LM3671 family chip that the lithium ion battery supply voltage of 3.0 ~ 4.2 V is converted to 3.3 V, maximum output current is 600mA, when entering dormant state, 3.3V the quiescent current of power supply chip is only 16 uA, and the GS1010 controller can cut out 1.8 V power supplies of kernel by the enable pin of power supply chip, the cut-off current of 1.8 V power supply chips is only 0.01 uA.Filtering transceiver module 5 adopts 2.45 GHz bandpass filter, and making microstrip line between radio-frequency front-end and antenna port and the impedance of antenna is 50 ohm.
