Description
Technical field
The present invention relates to the information gathering transmission technique field, particularly a kind of environmental monitoring system based on zigbee technology and Ethernet.
Background technology
Environmental parameter and industrial and agricultural production and people's lives are closely related, and as warehouse, farmland, production process, humidity is crossed conference and caused that grain goes mouldy and goes bad; Variations in temperature can influence grain quality; Precision instrument, semiconductor device can be crossed wet performance because of excess temperature and reduce.In addition, along with the raising of people's quality of life, the high request of indoor environment is also needed real-time monitoring to environmental parameter.
Environmental parameter transducer in the past is that wired mode transmits data mostly, and circuit is redundant complicated, is not suitable for most amount placements on a large scale, the wiring cost height, and the problem of aging of circuit has also influenced its reliability.On the other hand, the desired wireless technology of networked transducer is different from more existing radio network techniques now, and this network does not need too high transmission rate, but in the requirement that the comparison harshness is arranged aspect cost and the power consumption.Chang Yong wireless communication technique comprised WiFi in the past, Bluetooth, UWB etc., the complicated cost height of WiFi equipment, the too big cost of Bluetooth power consumption can fall yet, UWB is owing to most of bandwidth of electric wave is taken by infrastructure such as radio communications, can not arbitrarily use, adding the electric wave power output of UWB will control on the level below the noise that does not influence other radio communications as far as possible, therefore the ultimate range that can communicate by letter also has only about 10m, and they are not the desirable communication technologys of framework wireless environment parameter sensors network.
Be similar in order to satisfy that the environmental parameter transducer is small-sized like this, the requirement of low-cost equipment Wireless Networking, the ZigBee technology produces also and grows up.The ZigBee technology is to grow up on the IEEE802.15.4 basis, be up-to-date a kind of closely, low complex degree, low-power consumption, low data rate, two-way wireless communication technology cheaply, can be operated on 2.4GHz (whole world is popular), 868MHz (Europe is popular) and these three frequency ranges of 915MHz (U.S. is popular).Its major advantage is as follows:
1) low in energy consumption: under the low power consumption standby mode, common No. 5 dry cells of two joints can use more than 6 months, and this also is the unique advantage that the ZigBee supporter is be proud of always;
2) time delay is short: ZigBee should be used as optimization at what time delay had a strict demand, and communication delay and the time delay that activates from resting state are all very short.Equipment representative value search time is 30ms, and device activation time representative value is 15ms, and vehicular equipment channel turn-on time is 15ms;
3) cost is low: the ZigBee message transmission rate is low, and agreement is simple, greatly reduces cost;
4) network capacity is big: each ZigBee network can be supported 255 equipment at most, and namely each ZigBee equipment can be connected with other 254 equipment;
5) reliable operation: in order to improve the reliability of transmission data, ZigBee has adopted carrier sense multiple/conflict to avoid channel access way and the complete Handshake Protocol of (CSMA/CA).
6) working frequency range is flexible: the frequency range of use is respectively 868MHz (Europe), and 915MHz (U.S.) and 2.4GHz (general) are unlicensed band, need not to apply for the registration of.For China, have only the general frequency range of 2.4GHz to need not application at present.
Because characteristics and the advantage of ZigBee technology, just embodied its superiority based on the exploitation of the wireless device of ZigBee.At present aspect wireless senser, have patent " Bluetooth wireless transducer " based on the wireless senser aspect of Bluetooth technology (number of patent application: 2003105080.9), but be based on the ZigBee technology, the related news that can be used for the network-enabled intelligent environmental parameter transducer of various complicated flexibly do not appear in the newspapers.
