Description
Technical field
The present invention relates to a population honeybee network system, particularly a kind of group honeybee network standby system that there is redundant telegon and can keep group honeybee network on-line.
Background technology
Group honeybee network (ZigBee) is short-distance radio network agreement, media access layer (MediumAccess Layer, MAC) with physical layer (Physical Layer, PHY) be adopt IEEE802.15.4 standard, support multiple network topology, as tree topology (Tree), mesh topology (Mesh), and star topology (Star), its advantage is low power consumption, low cost and the easily a large amount of network node of layout, therefore be widely used in sensor network, as monitoring environment learns temperature, tide water level changes, and for example digital home, each power consumption of home appliances and conditional control appliance switch can be monitored, and emergingly to apply in remote medical-treatment, comprise chronic disease, heart disease and basic health-care, because medical sensor network is all the pulse blood pressure collecting patient usually, the data such as body temperature and mobile status, medical data data volume is simple and transmission quantity is little, the low transmission rate of Zigbee and low complex degree can fully reach reliable transmission quality.The power of Zigbee itself is low in addition, little to human health damage, is the good selection of medical applications.
But, Zigbee specifies that each personal area network (Personal Area Network (PAN)) will have the telegon (Coordinator) of only, whole PAN is in charge of by telegon, it similarly is initialization network, new node is allowed to add network, and network end-point transducer is after adding network, telegon can be given sense data at these transducers of predetermined condition, then telegon is transmitted to server again (also known as Sink, the final receiving terminal of data), because Zigbee is mainly used in sensor network, collect the data of all the sensors, there is Sink server, therefore the role of telegon is very important.If telegon is ineffective, whole PAN network just cannot manage, sensing data more cannot give Sink server, but, Zigbee specifies that each PAN only has a coordinator, the telegon that therefore cannot another telegon be had again to take over inefficacy works on, therefore, if telegon lost efficacy, whole PAN network will be ineffective, and Sink server just cannot receive the data of transducer inside whole PAN, affect very large, so the redundant function of Zigbee telegon is in demand, the reliability of PAN network significantly can be increased.
Therefore, how to design and a kind ofly automatically can recover online group honeybee network standby system when telegon lost efficacy, desire most ardently by inventor a large problem of solution.
Summary of the invention
Main purpose of the present invention is to overcome the deficiencies in the prior art and defect, proposes a kind of group honeybee network standby system having redundant telegon and can keep group honeybee network on-line.
For reaching above-mentioned purpose, the invention provides a population honeybee network standby system, comprise a group honeybee and coordinate group, there is initial coordination unit and a redundant coordination unit, wherein, the firmware of this initial coordination unit memory architecture group honeybee network, this redundant coordination unit detects this initial coordination unit and the firmware of this framework of internal memory group honeybee network; And at least one terminal installation, signal connects the initial coordination unit that this group of honeybees coordinate group, and the online firmware of internal memory autoboot; Wherein, when this initial coordination unit lost efficacy, this redundant coordination unit sends a renewal message by the firmware of this framework group honeybee network of internal memory, this terminal installation receives this renewal message, sets up signal be connected by the online firmware of the autoboot of this terminal installation internal memory with this redundant coordination unit.
