The next intelligence instrument is one kind in intellectual water meter, intelligent electric meter, intelligent gasometer, intelligent charging spot.
The Refresh Data cycle in the isolated data storehouse is 168 hours~720 hours.
The radio receiving transmitting module is preferably passed using WSN nets transport module, GSM/GPRS wireless transport modules, power carrier
In defeated module it is a kind of come realize the communication of Relay Server and host computer connect.
Ciphering unit is connected with the isolated data storehouse, and is connected by the ciphering unit with rfid uint, with
The data that intelligence instrument is transferred in isolated data storehouse are prevented to be tampered by way of data encryption.
Beneficial effect：The utility model is realized long-range fast by way of wired meter reading and wireless data transmission are combined
The accurate meter reading of speed, a sets of data is subjected to two sets of processing, at the same using wired connection mode one side and host computer it is direct-connected come
Carry out data transmission, while data packing and data progress that is temporary, then being received with upper computer end are carried out using Relay Server
Contrast and corrigenda operation, meanwhile, be additionally provided with radio frequency unit be read out it is convenient manually check on the spot, there is reliability
The advantages that high, easy to operate, anti-collision, encryption performance are good, also saving labour and time, convenient management.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to a kind of preferred embodiment of Fig. 1 long-distance meter-reading system based on Internet of Things, in the present embodiment, remotely copy
Table system is applied in the long-range water meter reading system in a certain cell, including host computer 1 is arranged at six groups under host computer 1
Relay Server 2, every group of Relay Server 2 corresponds to independent building respectively, and includes 30 family users in every building, that is, sets
There are 30 intellectual water meters as the next intelligence instrument 3.
Wherein, encoder 301 and RS485 buses, encoder are included on the next intelligence instrument 3 in user family
301 front ends are read out and encoded to the data on intelligence instrument 3, and back segment is provided with two groups of data outlets, and one group of data goes out
