Description
技术领域 technical field
本发明涉及工业无线传感网络领域，特别是涉及一种基于工业无线传感器网络的路由分区调度装置。 The invention relates to the field of industrial wireless sensor networks, in particular to a routing partition scheduling device based on industrial wireless sensor networks.
背景技术 Background technique
以较低的投资和使用成本实现对工业全流程的“泛在感知”，获取传统由于成本原因无法在线监测的重要工业过程参数，并以此为基础实施优化控制，来达到提高产品质量和节能降耗的目标。然而，由于工业现场环境复杂，信道容易受到干扰，如果采用单信道的通信模式，当该信道受到干扰而无法通信时，将使整个网络通信中断，影响数据传输，在工业通信中对数据的可靠性和实时性常难以实现，这样的通信中断往往是不能容忍的。目前，具体有以下三种工业无线路由感知通信解决方案： Realize the "ubiquitous perception" of the entire industrial process with low investment and use costs, obtain important industrial process parameters that cannot be monitored online due to cost reasons, and implement optimal control on this basis to improve product quality and energy saving consumption reduction goals. However, due to the complexity of the industrial site environment, the channel is susceptible to interference. If a single-channel communication mode is used, when the channel is interfered and cannot communicate, the entire network communication will be interrupted, affecting data transmission. In industrial communication, the reliability of data Real-time performance and real-time performance are often difficult to achieve, and such communication interruptions are often intolerable. Currently, there are three specific industrial wireless routing-aware communication solutions:
（1） 基于WIA-PA协议的集中式和分布式相结合的多信道和跳频技术路由算法； (1) Based on WIA-PA protocol centralized and distributed combination of multi-channel and frequency hopping routing algorithm;
（2） 基于HART协议的图表路由算法； (2) Chart routing algorithm based on HART protocol;
（3） 基于ZigBee协议的路由方法； (3) Routing method based on ZigBee protocol;
（4） Dijkstra 算法 (4) Dijkstra algorithm
（5） K短路径算法 (5) K short path algorithm
通过分析，方案（1）方法结构复杂，适用于无线网络中对实时性要求不高且数量占绝大多数的数据报文的转发。选择出来的路径不一定是延迟最小的路径，并不是最优的；方案（2）所有的网络节点必须事先配置好图表路由，因此冗余度和随机性较差；另外，无线HART网络中节点之间的跳数有限，网关与任意节点的通信延迟比较大。（3）结构显得太过复杂，效率精度有待提高，在网络拓扑变化很快的无线传感器网络中，导致Zigbee路由能耗过大，降低了节点通信效率。（4）和（5）不适用于动态网络中低功耗和低时延发现新的转发路径，以上方案远远不能满足高精度、低成本、高效益实现与大量远程的可移动并作为终端用户界面的机器装置联系起来，实现物联网数据的定位采集和传输，高效地使用传感器节点的能量，延长网络的存活时间。 Through analysis, scheme (1) has a complex structure and is suitable for the forwarding of data packets that do not require high real-time performance and account for the vast majority of data packets in wireless networks. The selected path is not necessarily the path with the smallest delay, and it is not optimal; scheme (2) all network nodes must be configured with graph routing in advance, so the redundancy and randomness are poor; in addition, nodes in the wireless HART network The number of hops between them is limited, and the communication delay between the gateway and any node is relatively large. (3) The structure is too complex, and the efficiency and accuracy need to be improved. In the wireless sensor network with rapid network topology changes, the energy consumption of Zigbee routing is too large, which reduces the communication efficiency of nodes. (4) and (5) are not suitable for finding new forwarding paths with low power consumption and low latency in dynamic networks. The above schemes are far from meeting the requirements for high-precision, low-cost, and high-efficiency implementations and a large number of remote mobile devices that can be used as terminals. The machine devices of the user interface are connected to realize the location collection and transmission of IoT data, efficiently use the energy of sensor nodes, and prolong the survival time of the network.
