As shown in Figure 1, communication network overall architecture is a kind of multiband multi-channel transmission pattern, multiband multi-channel transmission and business data flow in the present embodiment incorporate in application layer, application layer is marked off an application sublayer, described application layer is provided with application layer host state machine, and described application sublayer is provided with application support sublayer host state machine and application support sublayer receives state machine；

In the present embodiment, application layer principal function achieves tens kinds of electric power protocol-driven and data collection application, and runs sequential from formation network, networking to the protocol stack of data communication。System administration, network management and safety management are positioned at operation backstage。Application layer design framework mainly includes networking, application list report, resource distribution and user's application process four part, and its concrete design framework is as shown in Figure 2。230MHz subnet is connected with 433MHz or 470MHz or the 780MHz subnet of the other end by the present embodiment by communication processor。
In the present embodiment, due to apart from problems such as remote or barrier block, the star network topology of single-hop can not be suitable for some special application scenarios, the tree type network based on multi-hop cascade communication or mesh network should be adopted, most routing algorithms only consider a kind of situation the affecting network service interpretational criteria as algorithm, only consider channel quality in some researchs。And in another part algorithm only using the communication delay in link as the criterion seeking optimal path, in practice, the packet loss phenomenon of data communication when the channel of communication link is poor, can be caused。Aloft adopt electromagnetic mode to propagate due to data, speed is exceedingly fast, and the end-to-end delay caused in being wirelessly transferred process is negligible, and therefore the main slot offset produced by with deterministic schedule of communication delay is relevant。Additionally, if some node loads on selected optimal path are excessive, energy loss is too fast, will reduce the life-span of its battery, and also result in whole unstable networks, internodal slot offset that the present embodiment distributes according to deterministic schedule and the channel quality of hop channel process, the path choosing the best carries out data communication, concrete, as seen in figures 3-6, using slot offset produced by deterministic schedule and in hop channel process the channel quality of selected channel as two weights, be designated as G respectivelysAnd Gq, by abstract for IPv6 Sensor Network subnet be two weighted graphs with this two groups of weights composition respectively, respectively with GsAnd GqMark。Each edge in each directed graph has corresponding weights。Slot offset, it is determined that property scheduling is when meeting time synchronized, distributes to each node in network by corresponding time slot in superframes and is used for its data communication。Source node can be orderly in the time slot that deterministic schedule distributes transmission data；Meanwhile, the data message that the reception source node that the destination node of correspondence is also orderly on predetermined time slot sends over。All of terminal unit is intended to the time slot transceiving data according to scheduling entity distribution。Channel quality, according to IEEE802.15.4-2006 standard, works in global general free 2.4GHzISM frequency range, has 16 channels (11-26) to select。In this frequency range, also having coexisting of other wireless short-distance networks, such as IEEE802.11 network, based on the wireless network (ZigBee, wireless HART, WIA-PA) of IEEE802.15.4 standard, bluetooth and RFID system etc.。In order to prevent the interference of these equipment being operated in similar frequency bands, it is necessary to adopting hop channel technology, to reduce the equipment time at each multi-channel operation, thus decreasing the interference to network itself of other equipment, also reducing the impact on other wireless devices。But, disturbed probability is all there is corresponding to every channel corresponding to time slot in path, different channels also can affect route and make the communication of data after Path selection, as seen in figures 3-6, only consider slot offset, in the path meeting scheduling requirement, it is possible to link-quality is poor, so will increase network overhead, waste the communication resource。Routing algorithm in the present embodiment can ensure that deterministic schedule and channel quality are optimum simultaneously。
As it is shown in fig. 7, in the present embodiment, network adopts distributed administration of energy conservation scheme, and whole network has multiple energy manager, and energy manager process runs on inside routing device, and each energy manager manages respective multiple sub node equipment respectively。Energy management is mainly by the energy management process (EMAP) in node device and what energy manager completed jointly, in the entire network, energy management process (EMAP) accepts the management of energy manager, and energy manager can arrange various configuration parameter and state parameter (if data sending time slots, transmission state are that compression sends or long data frame sends)；In individual node equipment, adopt deep-sleep, radio frequency dormancy and dynamic data buffer memory, selectively carry out data compression transmission or long data frame sends, and the dynamic setting of various power save parameters (such as deep-sleep time slot, data buffer storage time slot) is carried out by energy management process (EMAP)。At transport module in the collection of monitored data (such as electric current, voltage and electric energy etc.), storage, analysis process, transport module starts dormancy mechanism, thus saving energy consumption；When monitored data fluctuations is less, node device can increase self dormancy time automatically, and does not change wakeup time, thus adding the ratio that transport module power save mode is shared within the whole service time, has reached the purpose of power save mode Automatic Optimal；Data are carried out buffer memory transmission, the data repeatedly monitored once just are sent, thus also saving energy consumption by the data buffer storage queue depth that transport module requires according to energy manager simultaneously；When monitored data value is bigger, it is also possible to carry out data compression transmission according to the requirement of energy manager, decrease the length of Frame, thus further reducing energy consumption。Transport module starts energy management process initialization relevant parameter, energy saving in running UAP afterwards, first, penetration depth resting state (CPU, acquisition module, memorizer, radio-frequency module fully enters resting state, only internal dormancy intervalometer is in running order), through deep-sleep time slot TdsiAfter time, node device is waken up by doze output by internal interrupt mode, transport module enters (the only radio-frequency module dormancy of radio frequency resting state from deep sleep state, other parts are waken up), in radio frequency resting state, acquisition module gathers such as field datas such as flow, temperature, pressure, rotating speeds, and data are stored。At radio frequency resting state time slot, transport module is according to the data queue's analytical data situation of change gathered, and percentage regulation dormancy time slot Tdsi。Transport module judges that data queue that local acquisition module gathers is whether more than the minimum data number DN of starting algorithmmin, in order to monitored data situation can be made accurate analysis；If data queue is more than the minimum data number of starting algorithm, node device is automatically adjusted the deep-sleep time slot T of this localitydsi, the otherwise node device repeated priming energy management process when radio frequency dormancy time slot terminates。The communications band of final module include 230MHz 433MHz 470MH 780MHz tetra-frequency range, interface mode includes RS232 or RS485 or Ethernet etc., and power supply mode includes plug-in and battery type。
