Abstract
The invention provides a method for detecting the network construction speed based on the Zigbee. The method comprises network flow detection and network delay detection. The detection range of the two kinds of detection is 75-5000 meters, the network flow detection is that data packages are sent to all user terminals on a server of a service provider through a Zigbee protocol in a memory contract multithread mode, the user terminals download the data packages, and the download rate and the broadband access rate signed by users are compared to obtain a detection result. The network delay detection is that at least 5 web portals are selected at the user terminals, the user terminals simulate users to input website URL addresses to browse the web on the server of the service provider, and information of Zigbee service availability, DNS delay, TCP delay and Zigbee page first package delay is obtained, and then a detection result is obtained. The method has the advantages of being good in stability, low in cost and power consumption, and high in accuracy, and reliable technological support is provided for the users to obtain accurate service provider broadband data.
Description
Technical field
The present invention relates to a kind of detection method of network speed, particularly a kind of network struction speed detection method based on Zigbee.
Background technology
ZigBee is the synonym of IEEE 802.15.4 agreement.According to the technology of this agreement regulation, it is the wireless communication technology of a kind of short distance, low-power consumption.Its communication distance is from 75 meters of standard to hundreds of rice, several kilometers, and supports infinite expanding.In theory, ZigBee be one by a wireless-transmission network platform that can how to form to 65000 wireless transport modules, in whole network range, between each ZigBee-network transport module, can intercom mutually.ZigBee-network is mainly to set up for industry spot automation control data transmission, thereby it has simply, easy to use, reliable operation, the feature that price is low.Particularly, ZigBee-network following points advantage:
(1) low-power consumption.Under low power consumption standby mode, No. 5 dry cells of 2 joints can be supported 1 node work 6～24 months, even longer.This is the outstanding advantage of Zigbee.The lower bluetooth of comparing can only be worked several weeks; WiFi works a few hours only.
(2) low cost.By significantly simplify agreement (less than bluetooth 1/10), reduced the requirement to communication controler, by forecast analysis, the 8 8-digit microcontroller measuring and calculating with 8051, Full Featured host node needs 32KB code, and subfunction node is few to 4KB code, and Zigbee exempts from agreement patent fee.The price of every chip block is approximately 2 dollars.
(3) low rate.Zigbee be operated in 20～250kbps compared with low rate, the initial data throughput of 250kbps (2.4GHz), 40kbps (915MHz) and 20kbps (868MHz) is provided respectively, meet the application demand of lower rate transmissions data.
(4) prolong in short-term.The response speed of Zigbee is very fast, generally from sleep, proceeds to operating state and only needs 15ms, and node connection enters network only needs 30ms, has further saved electric energy.Compare down, bluetooth needs 3～10s, WiFi to need 3s.
(5) high power capacity.That Zigbee can adopt is starlike, sheet and mesh network topology, by a host node, manages some child nodes, and maximum host nodes can be managed 254 child nodes; Host node also can, by last layer network node control, can form at most the large net of 65000 nodes simultaneously.
(6) high safety.Zigbee provides three level security patterns, comprises without security settings, uses access control inventory (ACL) to prevent the symmetric cryptography that illegally obtains data and adopt Advanced Encryption Standard (AES 128), to determine flexibly its security attribute.
(7) unlicensed band.Adopt direct sequence spread spectrum at industrial science medical treatment (ISM) frequency range, 2.4GHz (whole world), 915MHz (U.S.) and 868MHz (Europe).
Each Zigbee network node not only itself can be used as monitored object, for example its transducer connecting directly carries out data acquisition and monitoring, automatically other network node of transfer passes the data information of coming, and therefore when a network node breaks down, can not affect the proper communication of whole network.
The detection technique of existing Internet speed is generally the mode of wire transmission, the complexity but this mode connects up, and cost is high, once transmission cable damages, whole supervisory control system cannot work.Also having the mode that adopts wireless transmission, be generally based on bluetooth, WiFi Radio Transmission Technology, but this mode is with high costs, poor stability, and high power consumption, maintenance difficulties is high.
Therefore, need a kind of good stability, low cost, low-power consumption, wireless network that accuracy is high to build speed detection method, can utilize ZigBee-network agreement to carry out transfer of data.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of network struction speed detection method based on Zigbee be provided, overcome with high costs, poor stability, high power consumption, accuracy is the high difficult problem of high maintenance difficulty not.
In order to realize object of the present invention, be achieved in that
