Further, the ZigBee transmission equipment of Centroid adopts the F8114 equipment with ZigBee and GPRS network function.
Beneficial effect:
The most significant advantage of the utility model is that the remote transmitting system collection of wireless ZigBee data acquisition Real-Time Monitoring Building Deformation is stable, reliable, convenient, practical.Mounting cost is cheap, safeguards simple, does not need to rent public network, also need not huge operating cost.And this transmission system has wireless penetration, intellectuality, support are star-like, tree-shaped, the series of advantages such as multiple network topological structure such as Mesh network, along with the growth of demand and the further maturation of technology, wireless Zigbee has more wide application prospect in the remote transmitting system of Real-Time Monitoring Building Deformation.
Embodiment
As shown in Figure 1-2, the remote transmitting system of a kind of wireless ZigBee data acquisition Real-Time Monitoring Building Deformation of the present utility model, comprises front end monitoring data collection equipment 2, ZigBee transmission equipment and central monitor system 1.The data collected for realizing the parameter acquisition of each monitor node, and are sent to ZigBee transmission equipment by serial ports by front end monitoring data collection equipment 2.Each monitor node comprises Centroid 3 and general node 4.ZigBee transmission equipment is in the entire system for realizing the foundation of wireless network transmissions passage.After ZigBee transmission equipment receives monitor data from the front end monitoring data collection equipment 2 of each monitor node, by being sent to central monitor system 1 from the wireless network transmissions set up, simultaneously, central monitor system 1 also sends control command by wireless network to each monitor node, thus the two-way communication realizing data is to reach the object of remote measurement, remote control.
When central monitor system 1 is laid near front end monitoring data collection equipment 2, the ZigBee transmission equipment of each monitor node directly and central monitor system 1 wireless connections; When central monitor system 1 and front end monitoring data collection equipment 2 are distant, general node is first connected with Centroid by ZigBee transmission equipment, and then Centroid is connected with central monitor system 1 by GPRS network again.Concrete connected mode is as follows:
As shown in Figure 1, when central monitor system 1 is laid near front end monitoring data collection equipment 2, the wireless network that the transfer of data of each monitor node adopts ZigBee transmission equipment to set up directly carries out short-distance transmission access central monitor system 1, and whole ZigBee wireless network adopts F8914 to set up; As shown in Figure 2, when central monitor system 1 and front end monitoring data collection equipment 2 distant, the terminal data of general node 4 first passes through ZigBee wireless network transmissions to Centroid 3, then Centroid 3 transfers data to central monitor system 1 by GPRS network again, and Centroid 3 adopts the equipment F8114 with GPRS.That is, the ZigBee transmission equipment of general node 4 adopts the F8914 equipment only having ZigBee-network function, and the ZigBee transmission equipment of Centroid 3 then adopts the F8114 equipment with ZigBee and GPRS network function.
ZigBee transmission equipment can realize MANET function, maximumly supports 65000 nodes.Central monitor system 1 is primarily of server unit peace platform software composition.After central monitor system 1 receives monitor data, various analysis can be carried out to data, and carry out various control operation according to analysis result, as sent warning information or sending control command to each monitor node.
When data are sent to central monitor system 1 by GPRS network by Centroid 3, central monitor system 1 network has various network access modes:
(1) central monitor system 1 adopts APN special line, and all terminals all adopt Intranet to fix IP, and Call center, by an APN access via telephone line commmunication company GPRS network, sets up gre tunneling between GGSN and commmunication company's dlsw router.For client distributes special APN, other user must not apply for this APN.Only have the SIM card in this private network just can enter this APN, prevent entering of other disabled users.User can set up radius server in inside, to ensure user's internal security.User sets up Dynamic Host Configuration Protocol server (or in APN router, enabling DHCP function) in inside, be the user's distributing user home address by certification.
This kind of scheme no matter real-time, safety and stability comparatively before a kind of scheme have and greatly improve, be suitable for the applied environment that security requirement is higher, data point many, requirement of real-time is higher.Best networking mode when fund allows.
(2) central monitor system 1 adopts ADSL public network to connect, adopt public network dynamic IP+dns resolution service, client first contacts with DNS service provider and opens DDNS, then IP MODEM adopts domain name addressing system to connect dns server, find central monitor system 1 public network dynamic IP by dns server again, connect.This kind of mode can save the expense that public network fixes IP greatly, but stability is limited by the stable of dns server, so will find reliable DNS service provider.This kind of scheme is applicable to small-scale application.
(3) central monitor system 1 adopts ADSL public network to connect, and adopts public network to fix IP service, it is first to INTERNET operator application ADSL broadband services, and central monitor system 1 has public network to fix IP, and IPMODEM initiates to connect directly to central monitor system 1.Reliable stable, recommend this kind of scheme.
Be more than a specific embodiment of the present utility model, enforcement of the present utility model is not limited thereto.
