Embodiment one
Referring to Fig.1 and 2, the present embodiment provides a kind of new intelligent energy information collection pipes being different from the prior art
Reason method can realize that the reasonable management and control of the common resource/energy such as water, electricity, gas, heat, the method for the present embodiment are based on structure
The system of " energy information administrative center+star-like system gateway+teletransmission energy meter terminal " is realized.
Specifically, as shown in Figure 1, the system comprises center for information management 1, at least one system gateways 2 and extremely
Few one energy meter terminal 3.Between the system gateway 2 of each and its at least one energy meter terminal 3 having under its command
Based on the single star-like communication network of wireless communication connection type structure；Meter terminal determines it in a manner of being affiliated to corresponding gateway
It networks.Multiple star-like communication networks is generally comprised in structure, the gateway in each star-like communication network again in information management
The heart establishes long-range wireless communication connection, and data communication technology or WLAN can be based between gateway and administrative center
The communication technology connects, it is preferred to use the former 3G/4G networks.
Wherein, described information administrative center, hereinafter referred to as administrative center are made based on the upper software systems of server
Remote management and interaction are carried out with communication pair and its lower gateway connected.Meter terminal refer to intelligent low-power consumption without
Line energy meter terminal, can be water meter, ammeter, gas meter, hotlist etc., be considered as in systems from node, below abbreviation meter.
The communication host node of numerous meter terminals (from node) is the system gateway in star-like communication network, hereinafter referred gateway.From
The communication link of node to host node is gateway downlink communication channel, becomes Sub-G wireless channels a herein.
Based on above-mentioned system, in the method for the present embodiment, communication network is divided into two layers, upper layer is information
The telecommunication network that administrative center's active downlink accesses, lower layer are that meter actively establishes communication, gateway half actively executes downlink task
Star Network.
Following effect is realized with this：Real-time Communication for Power is combined with non-realtime traffic, preferential to ensure that meter node is operated in phase
Under low consumption conditions, while taking into account the real-time of upper layer centralized management.
The present embodiment is realized particular by following processes：
Administrative center carries out remote interaction by 3G/4G communication modes and gateway, and support is managed multiple gateways, together
When, each gateway can manage hundreds of to 1,000 meter nodes, constitute the wireless Sub-G Star Networks of one master and multiple slaves.
Referring to Fig.1 and 2, administrative center is carrying out copy reading, configuration and control with being real-time Communication for Power between gateway to meter
Before system etc., it is necessary to first specify and distribute subordinate meter node to gateway.
Specifically, if the meter node near intended gateway includes the relevant information typing of information and configuration needs
Administrative center and the deployment scenario for understanding them, then can by way of directly issuing meter white list to gateway realization table
Score is matched.Meter archives are loaded to gateway by administrative center, the specified meter group of gateway management is distinctly claimed, referred to as issues
Meter function of white name list.
If meter node deployment situation near intended gateway is simultaneously indefinite, meter ID or table number do not carry out sorting out and
Statistics or administrative center are not stored with their relevant information, then need that gateway is first allowed voluntarily to find that it is residing star-like
Meter node in network, after specified discovery end cycle, administrative center according to the meter information that is got from gateway and
Respective table score is matched and is affiliated on corresponding gateway by regulatory requirement.Wherein, the RSSI of every meter is anti-to a certain extent
The fine or not degree of the distance of Ying Qiyu gateways or itself residing communication environment, therefore can be selected to ensure to communicate stabilization
Select and the higher meter of signal strength be affiliated to this gateway, the meter of dtr signal be affiliated to it closer to another gateway, it is real
Now reasonably distribution and management.Specifically distributing and be affiliated to foundation is：Gateway receives the data that neighbouring meter reports and upload
To center for information management, there are three indexs to can be used as the reference frame being affiliated to：First, RSSI, the empirical value tested according to the application
General RSSI has not been particularly stable less than -110dBm communications, it is possible to consider that the meter that will be less than this signal strength is hung
Come to other gateway；Second is that communication success rate, it is assumed that it is 10 minutes that allocation list, which counts report cycle, center for information management search
Nearby meter for a period of time, such as 10 hours, it is found that certain meters report success rate relatively low, it is assumed that success rate is less than to certain gateway
90%, it is also considered as communicating unstable consideration and is affiliated to other gateway；Third, the meter node storage capacity of gateway, single gateway energy
The number of nodes enough managed be it is limited, when the meter terminal quantity of discovery being affiliated to exceed gateway capacity limit when, it is more
The part gone out should be affiliated to other gateway.
By above-mentioned, it is the selectivity referred to realize gateway search meter and available received signal strength indicator (RSSI)
It is affiliated to function, thereby guarantees that the communication quality of meter and gateway, and then ensure the validity of management；In addition, gateway supports meter
White list issues management, filters out unrelated meter data.
After completing meter distribution, gateway, which will cache to have the latest data information sent on meter under its command and store, to be frozen each table day
Knot, moon freezing data, read in real time for center for information management.
In addition, control instruction and configuration information that gateway also issues meter cache information administrative center, wait for meter
It is handled when waking up.The control instruction is as closed valve order, parameter read/write command, open/close lock order.Due to gateway and table
Meter communication is initiated by meter, and when center for information management transmitting order to lower levels, perhaps meter is just in suspend mode, so gateway needs to delay
Depositing the order waits for meter initiation two-way communication that could execute or handle related command.The advantage of doing so is that：In information management
The heart need to only ensure to reach gateway under order, and gateway automatically processes follow-up work, and center for information management has executed without waiting
At task processing time being shortened, it is possible thereby to manage more gateways.
The major function of whole system is meter continuous data copy reading, followed by carries out meter control or systematic parameter once in a while
Configuration, totally unnecessary worry cache command is too many and causes gateway processes excessively complicated or busy problem.
In a specific embodiment, as shown in Fig. 2, the interaction between administrative center and gateway specifically includes：
S200：Administrative center loads meter archives to gateway, is distinctly claimed the specified meter group of gateway management；
S210：Administrative center's request gateway statistics and the meter for reporting neighbouring normal work, realize meter search or hair
It is existing；
S211：Administrative center makes gateway stop search, and center for information management is by the part meter having found or whole meter

Embodiment two
Fig. 1 and Fig. 3 are please referred to, further extension refines the present embodiment on the basis of the above embodiment 1, specifically
It is bright as follows：
The method of the present embodiment makes meter work in two kinds of communication patterns, first, it only includes newest continuous data unidirectionally to report
And the short packet of current operating conditions (distributes suspend mode immediately to wait for after random time arrives next time once again using the T1 stochastic models of message
Give out a contract for a project), referred to as T1 patterns；Second is that realize that the T2 cyclic patterns that principal and subordinate's two-way communication designs (wait time-out to be received without under
Line command secondary dormancy), referred to as T2 patterns.The random time thresholding of T1 patterns can be set, and the period that enters of T2 patterns can set, they
Value depending on actual demand or battery capacity.
Following effect is realized with this：T1 patterns are random reported can effectively to avoid the hollow middle message superposition of same Star Network
Or collide, gateway acquires meter basic data to the maximum extent；T2 patterns reasonably realize meter Remote configuration or control.
The present embodiment is realized particular by following processes：
Here, first being illustrated to the random fashion of T1 patterns, it is assumed that random time thresholding is T1, after meter loads onto battery
It is random that t0 is waited for report the first bag data (t0≤T1), another random time t1 (t1≤T1) is calculated after having sent message, then,
The meter needs to wait for the side T1-t0+t1 that can send second of data, and third time transmission data needs to wait for T1-t1+t2, and (t2 is
The random time of third time), namely the difference of last time random time and random time thresholding T1 must be supplied.Can reserve in this way compared with
Other meter reported data is given in big time slot.
The message that T1 patterns report is that short packet applies message, carries meter ID, stoichiometric number number and meter current state three
Divide information, gateway to be cached after receiving its data, and constantly refresh follow-up, confidence administrative center needs real time data direct
It is read to gateway transmitting order to lower levels.
T2 pattern cycles are generally 1 day or a few hours (being much larger than T1), and meter is by the longer report of periodic report set
Literary data, content further include measuring parameter, messaging parameter, time other than meter ID, stoichiometric number number and meter current state
The configuration information of stamp etc. becomes long packet and applies message.Later etc. to be received, the meter institute windowing time is tw, overtime not receive
Any down order meter is from suspend mode is advanced into, and otherwise, executes or processing order, window time reclocking, repetition are straight
To finally no longer receiving order ability suspend mode.As shown in figure 3, for gateway, once the T2 pattern messages for having meter under its command are received,
It first checks whether the parameter of the meter needs to update, i.e., compares the parameter that the parameter reported in message has been deposited with itself one by one,
It is inconsistent, the parameter deposited is issued to meter；Then, search whether for the meter the down order being not carried out (such as
Control valve, control lock), if there is then issuing execution.Update meter parameter or transmitting order to lower levels need to wait for meter and return to implementing result, success
If allow meter suspend mode immediately, if unsuccessfully order can retransmit once or twice.
Referring to Fig. 3, the gateway of the present embodiment and the communication interaction process of meter are as follows：
S300：Meter T1 patterns random reported short packet data in specific period, is sent suspend mode immediately.
S310：Meter T2 pattern cycles report long bag data, wait the down order of gateway to be received, are kept for a period of time
Reception state.
S311：Gateway judges whether current meter parameter needs to update, and is to issue corresponding configuration order.
S312：Gateway judges whether the order being not carried out for being also directed to the meter, is to issue execution.
S313：If need not currently be inquired the meter, configure, control, gateway, which issues sleep command, makes meter
Into dormant state.
S314：The order that meter receives gateway is executed or is handled, and implementing result is returned.
S315：Issuing sleep command after gateway receives the correct response of meter and complete order is finished makes meter enter
Dormant state.
