Technical field
The present invention relates to intelligence instrument meter-copy collector installation site technical fields, more particularly to true based on analytic hierarchy process (AHP)
Determine the method for intelligence instrument meter-copy collector installation site.
Background technique
In recent years, with the extensive use of intelligence instrument, data acquire the mode for also gradually disengaging manual metering, more
Rely on the acquisition of wireless remote transmission data.Instantly remotely control copy reading intelligence instrument mainly passes through Lora and NB-Iot telecommunication.
Wireless remote transmission intelligent meter is grouped as by mechanical base table and electronic control unit, even if electronic section breaks down, intelligence
Energy table still accurately measures, and wireless communication can under the premise of taking into account low-power consumption using the LoRa wireless communication technique of mainstream
Realize the communication function of long range.For concentrator uplink by public network and master station communication, downlink is wirelessly logical with intelligent meter by LoRa
Letter, communication data are encrypted using soft and hardware, are guaranteed data security.For that can be carried out by repeater apart from too far intelligent meter
Relay forwarding communication.
At present during Lora data acquisition, due to the diversity and complexity of Lora intelligence instrument installation environment
Property, the data acquisition success rate and correctness of Lora intelligence instrument be not high.
It is currently installed on the experience progress addressing installation that concentrator relies primarily on engineers and technicians.Intelligence is likely to occur after installation
Energy table causes signal of communication weak with concentrator hypertelorism, the acquisition failure of table data.It may also be installed in somewhere concentrator close
Collection leads to the additional wasting of resources.
Summary of the invention

Lora intelligence instrument population groups, if only remaining a group, cluster process terminates；
If 2) multiple groups remaining, two groups A and B that wherein distance is nearest are found；
3) judge the distance between A and B whether to be greater than preset threshold that (and the communication distance of scene Lora intelligence instrument has
Close), that is, cluster termination condition；If then cluster process terminates；
4) if it is less than preset threshold, A and B are merged into new group C, and use average link (Average Linkage)
Update the distance of C to every other group；
5) repetitive process 1 to 4 is until end of clustering.
Further, using average link method when the distance between the calculating group and group；
I.e. the distance between two groups be in group A all tables to group B in all tables distance arithmetic average；
All tables are constituted the data structure of a two-dimentional doubly linked list by polymerization in space before starting, polymerize each time
Two groups before polymerization are deleted from doubly linked list afterwards, new group after polymerization are placed on to the initial position of doubly linked list, then
The distance value of new group and other groups after updating polymerization.
Further, the cluster termination condition is when the distance between the smallest two groups of all group inner distances are greater than locality
Lora Intelligent Instrument telecommunication distance R.
The technical scheme provided by the application includes following advantageous effects: one kind determining Intelligent Instrument based on analytic hierarchy process (AHP)
The method of table meter-copy collector installation site, its special feature is that: in the customer profile information using new installation intelligence instrument
Latitude and longitude information, the distance between computational intelligence instrument；
Then in conjunction with live geographical environment and building etc. factors, field survey locality Lora intelligence instrument telecommunication away from
From, and the value is saved in system to use as step analysis termination condition；
The algorithm that the present invention uses uses bottom-up hierarchical clustering, and cluster starts preceding using each table as individual one
A group, then the gradually nearest group of combined distance, then updates the distance between new group and other groups using average link method,
Until all groups merge into a group, or the condition that satisfaction cluster terminates.
After end of clustering, its central point, each group of central point, which should exactly install Lora collection, to be determined to each group after cluster
The position of middle device.The case where for outlier (single table be one group) after end of clustering, if the table with apart from nearest group
Can be communicated by repeater then can reload signal repeater, otherwise the table needs separately installed concentrator；
Lora concentrator installation site is determined using analytic hierarchy process (AHP), guarantees that Lora signal covers all Lora Intelligent Instruments
The case where table, the installation number and concentrator signal for reducing concentrator interfere with each other, increase Lora wireless remote transmission intelligent instrument with
The success rate of concentrator communication, improves the stability of communication and the correctness of data.
