Technical field
It the utility model is related to field of electrical equipment, more particularly to a kind of intelligent meter data recording system based on NB-IoT.
Background technology
The long-distance meter-reading system of intelligent electric meter is generally made of ammeter, collector, concentrator and main website at present, wherein ammeter
Physical communication is carried out using RS485 with collector, collector generally carries out physical communication using power carrier with concentrator, concentrates
The communication mode of device and main website generally carries out physical communication using GPRS, and power line has impulse disturbances inherently,
In each ac cycle, there are two minor peaks, two minor peaks can bring impulse disturbances twice, while power line makes carrier signal
Cut down into height, when load is very heavy on power line, line impedance causes to cut down the height of carrier signal up to less than 1 ohm, real
In the application of border, when power line is unloaded, point-to-point carrier signal can be transferred to several kilometers but when load is very heavy on power line, only
Tens meters can be transmitted, so when signal on power carrier transmit when can there are it is unstable the problem of.
The content of the invention
It is an object of the invention to：Solves the problems, such as the jitter that existing power line carrier, PLC is brought, there is provided one
Intelligent meter data recording system of the kind based on NB-IoT.
The technical solution adopted by the present invention is as follows：
A kind of intelligent meter data recording system based on NB-IoT, including intelligent electric meter, further include concentrator and are used for and concentrator
The main website of wireless communication, the concentrator includes being connected with intelligent electric meter to communicate for obtaining the RS485 of ammeter information data
Module, the signal for RS485 communication modules to be obtained carry out the NB-IoT communication modules of wireless remote transmission and for analyzing
Judge to input and control the control module of output, the RS485 communication modules and NB-IoT communication modules are connected with control module.
In order to make the concentrator adapt to the ammeter of various communications protocols, the concentrator is further included for that will use
The ammeter information data of DL-T645 communication protocols are converted to be believed for the communication protocol of wireless remote transmission for Q/GDW 376.1
The protocol conversion module of data is ceased, the protocol conversion module is connected with control module.
In order to enable the concentrator real-time report fault message, the concentrator is further included for detecting fault message
Fault detection module, the fault detection module are connected with the control module.
Preferably, the fault message includes RS485 communication lines failure and electric meter fault two types.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. employ with the NB-IoT for covering wide, support magnanimity connection, low-power consumption, low module cost and low communication cost
Communication module, avoids signal and uses electric force carrier transmission, solves the jitter band that existing power line carrier, PLC is brought
The problem of dropout come and misinformation；
2. employ the ammeter that protocol conversion module makes concentrator adapt to various communications protocols；
3. realize the real-time Transmission of fault message.

A kind of intelligent meter data recording system based on NB-IoT, including intelligent electric meter, further include concentrator and are used for and concentrator
The main website of wireless communication, the concentrator includes being connected with intelligent electric meter to communicate for obtaining the RS485 of ammeter information data
Module, the signal for RS485 communication modules to be obtained carry out the NB-IoT communication modules of wireless remote transmission and for analyzing
Judge to input and control the control module of output, the RS485 communication modules and NB-IoT communication modules are connected with control module.
In order to make the concentrator adapt to the ammeter of various communications protocols, the concentrator is further included for that will use
The ammeter information data of DL-T645 communication protocols are converted to be believed for the communication protocol of wireless remote transmission for Q/GDW 376.1
The protocol conversion module of data is ceased, the protocol conversion module is connected with control module.
In order to enable the concentrator real-time report fault message, the concentrator is further included for detecting fault message
Fault detection module, the fault detection module are connected with the control module.
Preferably, the fault message includes RS485 communication lines failure and electric meter fault two types.
The intelligent electric meter carries out the transmission of signal with the concentrator by RS485 communication modules, and control module judges
The communication protocol of application layer then calls the protocol conversion module that application layer communication protocol is unified for Q/GDW when being DL-T645
Signal after uniform protocol is wirelessly transmitted to main website by 376.1 agreements, the control module by NB-IoT communication modules.
The fault detection module is detected transmitting fault information after failure to the control module, the control module
Fault message is sent to NB-IoT communication modules and is wirelessly transmitted to main website.
By above-mentioned implementation, the utility model can realize that the stabilization of kilowatt meter reading-out system signal is effectively transmitted, and concentrator can fit
Answer the ammeter of a variety of application layer communication protocol transmission.
