Description
Technical field
The present invention relates to a kind of kilowatt meter reading-out system, relate in particular to the low power consumption wireless meter reading system based on Internet of Things.
Background technology
In recent years, the requirement of To Intelligent Home is more and more higher, there is the reasons such as Human Error Rate is high, efficiency is low in the manual mode that needs full-time staff to visit to have checked meter, meter reading method starts to automation direction development, such as IC card Automatic meter reading system, RS-485 bus kilowatt meter reading-out system etc.The purpose of design of Automatic meter reading system is quality of life, operational reliability and the security for improving people.In the design process of residential quarters, robotization is checked meter and is conventionally had the function of intercommunication mutually with other system of Intelligentized System for Residence District, is also Property Management System important component part.
Wireless automatic meter reading technology is owing to not being subject to the restriction in geographic position, and without wiring, is considered to current state-of-the-art reading technique.This technology is checked meter conveniently, real-time is high, degree of accuracy is high, wide coverage, is saved manpower, also can be realized remote monitoring and remote maintenance by robotization means.In fact, radio communication itself have radio-frequency performance unstable, be subject to that environment scattering etc. causes that incomprehensiveness impact is large, the restriction such as communications band resource scarcity, co-channel interference are more serious, therefore have the difficulty that sizable technology realizes aspect, in addition, power consumption is also to realize one of bottleneck.Therefore, high-quality radio meter register network design seems extremely urgent.
At present, domestic aspect gas meter, flow meter wireless remote transmission checks meter, mainly experience two stages.
First stage: 2005-2009, be mainly the research of the wireless remote transmission reading technique based on ZigBee technology this period.
But these systems, only in development, are not promoted on market.Trace it to its cause, or due in gas meter reading industry, ZigBee exists fatal shortcoming:
(1) power consumption is higher, only can use 3-6 month, cannot meet the requirement of the gas meter, flow meter long-term work in kitchen.
(2) its frequency of operation is higher, generally adopts 2.4GHz.Frequency and its diffracting power are inversely proportional to.Cannot meet the requirement of gas meter, flow meter.
Subordinate phase: 2009 so far.This stage mainly concentrates on the research of the wireless remote transmission reading technique based on Internet of Things of 470MHz frequency range.470MHz is the free frequency range that is exclusively used in radio meter register of national regulation.
MSP430F449 is a kind of super low-power consumption FLASH type single-chip microcomputer, it has efficient 16 RISC kernels, 27 instructions, 125ns instruction cycle, according to low-power consumption and related request, this single-chip microcomputer can be widely used in gas meter, communication and home automation product and other low-power consumption application.In addition,, because ammeter and gas meter, flow meter also belong to different unit administrations, like this to the copying of each personal table, and separately to the bothering of user, can cause user and meter reading personnel's inconvenience.
Summary of the invention
Object of the present invention will provide that a kind of structural design is simple, with low cost, low in energy consumption, practicality is extremely strong exactly, can carry out the low power consumption wireless meter reading system based on Internet of Things that the intelligence of ammeter and gas meter, flow meter data is copied simultaneously.
In order to solve the existing problem of background technology, the technical solution used in the present invention is:
Low power consumption wireless meter reading system based on Internet of Things, it is made up of radio meter register data center and several pneumoelectric table counters, described radio meter register data center comprises radio network gateway 1, radio network gateway 2, region concentrator and remote data center, and described pneumoelectric table counter comprises wireless communication module, MSP430F449 module, ammeter and gas meter, flow meter; Radio network gateway 1, radio network gateway 2 in radio meter register data center carry out radio communication connection with region concentrator respectively, region concentrator and remote data center carry out two-way connection, wireless communication module in pneumoelectric table counter is connected with MSP430F449 module is two-way, MSP430F449 module is carried out two-way connection with ammeter and gas meter, flow meter respectively, and the wireless communication module in each pneumoelectric table counter and the radio network gateway of radio meter register data center carry out two-way communication.
Beneficial effect of the present invention is: be somebody's turn to do the low power consumption wireless meter reading system based on Internet of Things, structural design is simple, with low cost, low in energy consumption, practicality is extremely strong, can carry out the intelligence of ammeter and gas meter, flow meter data copies simultaneously, the restrictions such as the serious and power consumption of current existing wireless kilowatt meter reading-out system communication radio frequency unstable properties, communications band resource scarcity, co-channel interference is larger are solved, there is good dirigibility and reliability, be convenient to robotization and check meter and manage.
Brief description of the drawings
Fig. 1 is the theory diagram that the present invention is based on the low power consumption wireless meter reading system embodiment of Internet of Things.
Embodiment
As shown in Figure 1, low power consumption wireless meter reading system based on Internet of Things, comprise radio meter register data center and several pneumoelectric table counters, described radio meter register data center comprises radio network gateway 1, radio network gateway 2, region concentrator and remote data center, and described pneumoelectric table counter comprises wireless communication module, MSP430F449 module, ammeter and gas meter, flow meter; Radio network gateway 1, radio network gateway 2 in radio meter register data center carry out radio communication connection with region concentrator respectively, region concentrator and remote data center carry out two-way connection, wireless communication module in pneumoelectric table counter is connected with MSP430F449 module is two-way, MSP430F449 module is carried out two-way connection with ammeter and gas meter, flow meter respectively, and the wireless communication module in each pneumoelectric table counter and the radio network gateway of radio meter register data center carry out two-way communication.
