In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Embodiment is described in detail.
Embodiment one
Referring to Fig. 1, it is a kind of one of method flow diagram of data transmission method of the present invention, setting steps are introduced first
S100: one corresponding data transmission set with GPRS function is set for a pickup area, the pickup area includes
Multiple data collection points are that each data collection point in the multiple data collection point is arranged in unique corresponding data set
Device.
This step is the necessary setting steps for executing subsequent data transmission, but is not to require to execute each time, when
For a pickup area, this step only generally is needed to be implemented when just beginning to use technical solution of the present invention, when
After being provided with, for for this pickup area, when subsequent each progress meter reading, does not need substantially to execute this step.
It should also be noted that, pickup area described here can be understood as a residential area, an office building or
One market of person etc., multiple data collection points included by this pickup area can be to one be interpreted as in residential area
A specific region etc. in residential building, one layer of office building or market, the data concentrator can be total by m-bus
The wired connections such as line form and unit to be collected (such as the family in residential building, office building in corresponding data collection point
A region in one layer or a retail shop in the specific region of market etc.) water power hotlist (general abbreviation hotlist) led to
Letter, and acquire the meter reading data that generates in hotlist with this (communication mode is shown in national standard CJ/T188-2004 " family measuring instrument
Data transmission technology condition " standard), the data output end of data concentrator has GPRS function by wireless network and one
Data transmission set is connected.The data output apparatus can be specially the net with GPRS function in the technical solution of the present invention
It closes, alternatively, specifically the DTU by not having the gateway of GPRS function and with GPRS function is formed.The DTU be integrated GPRS without
Line wan communication and the terminal of RS232/RS485 wire communication can be received from RS232 interface/RS485 number of ports
According to then by GPRS wireless network, reception data are sent to monitoring center background server, are equally also received in monitoring
The various data and control instruction of central server are sent to the connected end end equipment of the RS232/RS485 interface of terminal.
Method includes the following steps:
S101: the data concentrator obtains the address mark of each unit to be collected in corresponding data collection point in advance；
What needs to be explained here is that since the m-bus agreement that hotlist is supported is generally poll system, hotlist itself
Data concentrator actively will not be sent by the meter reading data of generation, but need data concentrator in the data collection point of place
Each hotlist carry out active inquiry, acquire meter reading data.Therefore, where data concentrator must be obtained in advance and locally be saved
The address of all hotlists in data collection point identifies such as the information such as ID.The method for obtaining the address mark of hotlist in advance is asked
Referring to embodiment as shown in Figure 2, which is not described herein again.
S102: caused by the data concentrator is acquired according to address mark from corresponding each unit to be collected
Meter reading data includes the address mark of the corresponding unit to be collected in the meter reading data；
That is, in the collected meter reading data of this step include the meter reading data be to be collected from which block hotlist
, thus when the subsequent preservation to meter reading data is handled, it can be determined by the address mark carried in meter reading data
Corresponding relationship between meter reading data and the hotlist of unit to be collected out.
S103: the data concentrator sends the collected meter reading data to by preset wireless network described
Data transmission set, so that the meter reading data that the data transmission set will acquire is sent to background system, after described
Platform system according to corresponded in the meter reading data unit to be collected address identify determine the meter reading data with it is described
The corresponding relationship of unit to be collected.
Preset wireless network described here can be understood as that any wireless network exists in the prior art, as long as range
It is sufficiently large, the data concentrator of each data collecting point of pickup area can be enabled to send collected meter reading data
To the data transmission set of the corresponding pickup area.Moreover, when the data transmission set is not specifically by having
When the gateway of GPRS function and DTU composition with GPRS function, the gateway reception without GPRS function is from the number
According to the meter reading data that concentrator is sent, and send the meter reading data received to the coupled DTU, so that
The meter reading data that the DTU will acquire is sent to background system.
But in the case where national unauthorized, the cordless communication network built can only be using some of national regulation
It is disclosed, without the i.e. workable frequency range of application, such as 340M, 433M, 470M, 2.4G, but the power in these frequency ranges is all
Be it is strictly limited, be usually no more than 50mW, therefore under this wireless network environment, the communication distance of data concentrator is general
In 100m-400m or so, it is unpractical for concentrator one all in a cell to jump to gateway, it is therefore desirable to multi-hop without
Linear system system, that is, Wireless MESH network.
It will be described in detail when the preset wireless network is Wireless MESH network by embodiment shown in Fig. 2 below
Situation, referring to Fig. 2, it is the two of a kind of method flow diagram of data transmission method of the present invention, comprising:
Setting steps S200 please refers to content documented by the setting steps S100 of embodiment as shown in Figure 1.
S201 and S202 please refers to content documented by the S101 and S102 of embodiment as shown in Figure 1.
S203: the data concentrator sends the collected meter reading data to by preset Wireless MESH network
The data transmission set, so that the meter reading data that the data transmission set will acquire is sent to background system, institute
State background system according to corresponded in the meter reading data unit to be collected address identify determine the meter reading data with
The corresponding relationship of the unit to be collected.
It should be noted that step S204 to S208 is to the default step for how presetting Wireless MESH network in step S203
Suddenly, generally only just starting default Wireless MESH network or data transmission set powers on Shi Caihui and is performed, that is to say, that
The default step must be performed before S203.After the default step is completed, as long as data transmission set
Do not cause to re-power because restarting or powering off, the default step does not need to be performed when acquiring meter reading data every time.
S204: the data transmission set broadcasts the first beacon frame, the beacon frame includes the gateway when opening
Identity；The data transmission set in this step is the core of entire Wireless MESH network, the foundation of network topology and
Maintenance all realizes on the one hand the data transmission set has Wireless MESH network networking and communication by the data transmission set
(when such case, the data transmission set can be by the gateway without GPRS function and with GPRS function function
DTU is formed, and networking function is realized by the gateway, and to the function of background system transmission meter reading data by the DTU Lai complete
At), internet on the other hand can also be linked by modes such as Ethernet, GPRS, and (when such case, the data transmission is set
And it can be complete by the gateway to the function of background system transmission meter reading data for the gateway that can have GPRS function, networking
At can even not need the presence of DTU in this way).MESH network itself is meant that mesh network, but in technical solution of the present invention
In type of service be convergent type, the node (each data concentrator in a namely pickup area) in all mesh networks
Meter reading data collected requires to converge to the data transmission set, and therefore, real network topology is that tree structure is (but every
A node has a plurality of backup link to connect with the data transmission set), which generates in network construction.
What needs to be explained here is that the whole network is based on synchronous superframe and carries out periodic net when setting up Wireless MESH network
Network scheduling and maintenance, the structure for dispatching the superframe of data concentrator are as shown in Figure 3.Superframe length is macBeaconInterval,
Wherein dormancy time length is macSleepDuration, and activation Period Length is macMultisuperframeDuration.
The activation period is divided into macInterferenceNum period, and each period is a superframe unit, the length is
macSuperframeDuration.The foundation of sleep period can reduce the power consumption of concentrator, to guarantee practical business demand
Data concentrator can be used solar powered in the case where less.
Wherein, first superframe unit (namely has the function of GPRS or not by the data transmission set
Gateway with GPRS function is referred to as gateway in the embodiment shown in fig. 3 below) it initiates, the gateway broadcasts one first
A first beacon frame, the first beacon frame are mainly used to indicate Super frame parameter, such as how many superframe, each
Superframe duration etc., in addition subsidiary temporal information, (namely can receive for the gateway with one hop neighbor
To the data concentrator of beacon frame transmitted by the gateway) time synchronization.
The initial time of each superframe unit, all data concentrators listen to channel, according to what is listened to
The superframe configuration of itself is safeguarded or adjusted to Super frame parameter configuration information entrained by first or second beacon frame.Each data set
Middle device selects a superframe unit in multisuperframe as the stick unit of itself, and data concentrator exists
Data transmission is carried out in the stick unit of selection, and using other superframe units as data receipt unit, is being selected
When selecting the stick unit of itself, non-neighbours and supervisory stick unit need to be selected (cannot to select to close with the node of itself in other words
System is the stick unit that father node selected, the reservation that cannot also select other data concentrators adjacent with itself selected
Unit), it can guarantee each data concentrator in this way when data are sent, two-hop neighbors are (in the data set adjacent with itself
Device and the data concentrator adjacent with these data concentrators) it is sent without data, so as to avoid wireless collision, improve
The success rate of data transmission.
It should also be noted that, the data that DTU is received can be sent directly to background system due to the function restriction of DTU,
In this way using the prior art each data collection point setting DTU acquire meter reading data when, once need to carry out field adjustable or
On-site maintenance, live staff can not obtain field data and maintenance information directly from DTU, and can only rely on long-range
Work could be completed by contacting with background system so that it is this need scene carry out debugging maintenance working efficiency it is low and excessively according to
Rely the background system of distal end.And the gateway being connected by setting with DTU in technical solution of the present invention, so that needing to carry out live dimension
Staff can directly obtain required real time data from the gateway when shield, it is no longer necessary to which connection or calling backstage are
System, substantially increases the working efficiency and use scope of on-site maintenance in this way.
S205: when data concentrator receives first beacon frame, the data concentrator determine itself with it is described
Data transmission set is the node relationships of child node and father node；
Data concentrator described in this step can be understood as the gateway mentioned in above-mentioned embodiment illustrated in fig. 3
One hop neighbor.As long as meeting a certain range of data concentrator at a distance from the data transmission set, institute can be received
The first beacon frame is stated, to become a hop neighbor of the data transmission set.Moreover, because need to set up is convergent type
The network topology of tree, therefore can be transmitted according to the distance apart from the data transmission set, and with the data
Convergent point i.e. starting point of the equipment as the network topology of tree, determining between each data concentrator and
Node relationships (namely determining respective child node and father node) between the data transmission set.
S206: the data concentrator broadcasts the second beacon frame, and second beacon frame includes and the data concentrator
Fixed node relationships；
This step is referred to step S206 substantially, and difference is only in the main body for sending beacon frame from the data transmission set
A hop neighbor of the data transmission set is changed into.Thus the network topology of tree is allowed to set to far from data transmission
Standby direction is continued.
S207: when other data concentrators receive second beacon frame, other described data concentrators are determined certainly
Node relationships between body and the data concentrator for sending second beacon frame, and so on, determine the pickup area
Between interior all data concentrators and the node relationships between the data transmission set.
After having set up the Wireless MESH network, the data concentrator is pre- to be should be noted to step S201
First obtain the address mark of each unit to be collected in corresponding data collection point, comprising:
The data concentrator is identified from the address that the gateway obtains each unit to be collected in corresponding data collection point.
Data concentrator is in the case where batch production, it is impossible to the ID that all hotlists are written is realized in factory, it is inevitable
It to be written after the installation is completed at the scene, the mode that each data concentrator is written in batches is clearly unreasonable (data concentrator
The position of installation is generally approached in roof, dispersion and inconvenience), the gateway can pre-save to be needed in affiliated pickup area
The address of acquisition unit identifies ID in other words, and when accessing a data concentrator in Wireless MESH network, the gateway is according to institute
The address mark of corresponding unit to be collected is sent to the data concentrator by the position for stating data concentrator.
Moreover, the Wireless MESH network uses time-multiplexed mode to distribute time slot for each data concentrator, each
The adjacent data concentrator of the occupied time slot of data concentrator and adjacent data concentrator and the adjacent data concentrator
Occupied time slot is different.It in this way can be to avoid being likely to occur when carrying out data transmission using same slot transmission data institute
The conflict of generation.
The data concentrator, which passes through the collected meter reading data in advance, should be noted for step S203
If Wireless MESH network be sent to the data transmission set, comprising:
According to fixed node relationships, a corresponding father node transmission to selection collects the data concentrator
The meter reading data and the meter reading data that is received from other data concentrators, until every in the pickup area
A collected meter reading data of data concentrator sends the gateway by preset Wireless MESH network and sends out from the gateway
It is sent to the data transmission set.It can be transmitted further refering to Fig. 4 for data of the present invention under Wireless MESH network
Schematic diagram, Fig. 4 are specifically formed by not having the gateway of GPRS function with the DTU with GPRS function with the data transmission set
For be illustrated.Figure 4, it is seen that passing through selection apart from the farther away node of the gateway i.e. data concentrator
Meter reading data collected is converged to the gateway step by step by the father node of itself, for example node 401 sends out meter reading data
It is sent to its father node 402, node 402 sends it for the meter reading data that the meter reading data itself acquired and 401 are sent
At father node 403, node 403 by the meter reading data received (including the meter reading data of node 401 and 402) and itself
The meter reading data of acquisition is sent to the namely described gateway of its father node 400, and the data received are sent to by the gateway
DTU connected to it.It is also to be noted that the data transmission link between node shown in Fig. 4 is a kind of transmission mode
, each time when node-node transmission meter reading data, it is required to listen to the transmission quality of channel, when a certain section of letter of discovery link
The decline of number quality to a certain extent when, the channel for being best suitable for requirement can be selected to be transmitted, that is to say, that transmission link is not one
It is fixed, such as the at a time poor quality of the channel between node 401 to 402, it is not used to transmission data, node 401
It then can be by listening to selection to other node transmission datas, as long as final data converges to above-mentioned gateway.
Meter reading data it can be seen from the present embodiment by each data collection point acquisition in a pickup area passes through
Wireless network is sent to the data transmission set with GPRS function, and described in only will acquire as the data transmission set
Meter reading data is sent to background system, and the data transmission set, which can be one, has the gateway of GPRS function or by common
Gateway and DTU composition with GPRS function, are directed to a pickup area in this way, it is only necessary to use DTU even without
DTU can complete the function of needing multiple DTU to be just able to achieve originally, thus effectively control the maintenance cost of kilowatt meter reading-out system.
On the other hand, pass through base between each data collection point in data transmission set foundation and pickup area
In the connection of Wireless MESH network, is further supported from wireless network with this and passed using the data with GPRS function
Transfer device is that may achieve the function of needing multiple DTU to be just able to achieve originally.
