[0070] 本发明采用拓扑无线网络,引入中继概念实现所有输液监控节点与值班中心机之间的可靠通信,输液监控节点不仅可以直接与值班中心机进行无线通信,当无线网络环境复杂,部分输液节点与中心机间无法直接建立联系时,临近的输液监控节点便作为中继节点,担当路由器或父节点以实现互联互通,最终实现与值班中心机之间的通信。 [0070] The present invention employs a wireless network topology, the introduction of the concept of the relay reliable communications between all nodes infusion monitoring center duty machines, infusion monitoring node can only communicate directly with the wireless center duty machine, when the complex wireless network environment, part when infusion between nodes and the central unit can not establish a direct link near the infusion will be monitoring node as a relay node acts as a router or a parent in order to achieve interoperability, and ultimately the communication between the center and the duty machines. 以下对本发明的路由原理进行详细说明。 The following routing principles of the present invention will be described in detail.

[0071] 如图5所示,I为值班中心机,2-7为输液监控节点,且7为通信中继节点。 [0071] As shown in FIG 5, I is the duty Centers, infusion monitored nodes 2-7, and 7 is a communication relay node. 除中心机Iタト,其它节点,即2至7均由WiFi通信模块207 (ZigBee芯片)构建,Zigbee节点有两个地址:ー个16位网络短地址和ー个64位IEEE扩展地址。 In addition to the central unit Suites I ta, other nodes, i.e., 2-7 by the WiFi communication module 207 (ZigBee chip) construct, Zigbee node has two addresses: ー a short address and 16-bit network ー IEEE 64-bit extended address. 其中16位网络地址在网络内部使用,用于路由机制和数据传输。 16 wherein the internal network address of the network for routing and data transfer mechanisms. 该地址在节点加入网络时由其父节点动态分配的。 The addition of a network node address dynamically assigned by the parent node. 当网络中的节点允许ー个新节点通过它加入网络时,它们之间就形成了父子关系。 When the network nodes allow ー new nodes join the network which, between them to form a parent-child relationship. 在图5中,节点4为节点5和6的父节点,节点3为节点4的父节点。 In FIG. 5, node 4 to node 5 and 6 of the parent node, the parent node of the node 3 to node 4. 节点4、5、6构成ー个通信子网。 4,5,6 ー communication nodes constituting a subnet.

[0072] 当应用场景环境理想时,通信信号强度较好,值班中心机I可以直接作为路由器,作为根节点与所有的输液监控节点间进行通信,如图5中I与节点2间的通信。 [0072] When the environment over the application scenario, the communication signal strength is better, the duty machine center I can be used as a router, as between the root node and all nodes monitor the infusion communication, the two communication node I in FIG. 5. 当环境不理想时,有部分输液节点与中心机间无法直接建立联系,假设中心机I与节点2间的通信被阻断,但该节点可以与其它节点连接,即节点2可以与节点3建立通信。 When the environment is not ideal, and there is between the center portion of the infusion machine nodes can not establish a direct link, assuming the communication between the central unit 2 and the node I is blocked, but the node may be connected to other nodes, i.e. the node 2 and the node 3 may be established communication. 此时,应用动态路由规划,用多跳技术将节点2的信息经节点3实现与中心机间的通信。 In this case, the application programming dynamic routing, techniques with multi-hop communication between nodes 3 through node 2 implementation information to the central unit. 当所有的输液监控节点均无法与中心机建立连接时,可以在合适的地理位置增设输液检测节点,如节点7,并将该输液节点作为路由器或父节点,最终实现互联互通。 When all the nodes are unable to monitor the infusion establish a connection with the central unit, in an appropriate location may be an additional infusion detection node, such as node 7 and the node as a router or infusion parent node, ultimately to achieve interoperability.

[0073] 路由技术主要作用是为数据以最佳路径通过通信子网到达目的节点提供服务。 [0073] The main function is routing data serving node via the optimum route to the destination subnetworks. 路由协议是自组网体系结构中不可缺少的组成部分,其主要作用是发现和维护路由,主要有以下几个方面:监控网络拓扑结构的变化,交换路由信息,确定目的节点的位置,产生、维护以及取消路由。 MANET routing protocol architecture is an integral part, its main role is to route discovery and maintenance, mainly in the following aspects: monitoring changes in the network topology, routing information exchange, determine the location of the destination node, generating, maintenance and cancel the route. 为了达到低成本,低功耗,可靠性高的设计目标,本专利采用以下两种算法的结合体作为自身的路由算法。 In order to achieve low cost, low power consumption, high reliability design goals, this patent uses a combination of the following two algorithms as its own routing algorithm.

[0074] I) AODV :Ad-Hoc On-Demand Distance Vector (按需距离矢量路由) [0074] I) AODV: Ad-Hoc On-Demand Distance Vector (On Demand Distance Vector Routing)

[0075] 2) Cluster-Tree algorithm (树型网络结构路由) [0075] 2) Cluster-Tree algorithm (routing tree network structure)

[0076] ZigBee网络中,节点可以按照网络树状结构的父子关系使用Cluster-Tree算法选择路径。 [0076] ZigBee network, a node may use Cluster-Tree algorithm selects the network path in accordance with parent-child relationship of the tree structure. 即每ー个节点都会试图将收到的信息包转发给自己的后代节点,如果通过计算发现目的地址不是自己的ー个后代节点,则将这个数据包转发给自身上ー级的父节点,由父节点进行类似的判断处理,直到找到目的节点。ー per node will attempt to forward incoming packets to their offspring node, if the destination address is not found by calculating their ー offspring node, the packet is forwarded to the parent node itself ー level by similar parent node determination process until it finds the destination node. Cluster-Tree算法的特点在于使不具有路由功能的节点间通过与各自的父节点间的通信仍然可以发送数据分组和控制分组,但它的缺点是效率不高。 Features Cluster-Tree algorithm is to make the inter-node has no routing function may still send data packets and control packets over a communication between the respective parent node, but its drawback is that the efficiency is not high. 为了提高效率,ZigBee中允许具有路由功能的节点使用AODV算法去发现路由,让具有路由功能的节点可以不按照父子关系而直接发送信息到其通信范围内的其他节点。 For efficiency, ZigBee node having a routing function allows AODV algorithm is used to find the route, so that a node having a routing function can not directly send information to other nodes within its communication range according to the parent-child relationship.
