Problems solved by technology

[0004] In the prior art, most of the electricity consumption information collection using wireless communication network adopts 230 megabytes or GPRS methods. These collection methods have the problems of low transmission efficiency, long collection period, fast signal attenuation, and poor reliability.
Moreover, in the existing wireless communication network collection schemes, only narrowband channels are provided, and the speed and bandwidth cannot meet the requirements of the smart grid for real-time and interactive services in the power consumption link.
[0005] The recently proposed scheme of using EPON optical fiber dedicated line network to collect power consumption information, although this scheme meets the transmission bandwidth requirements of the smart grid for power consumption, it needs to lay a large number of optical cables in large-capacity residential areas and use a large number of ONUs unit, which increases the cost of input and wastes a lot of optical fiber resources, and it is still not applicable in terms of economic feasibility for scattered residential areas and remote rural areas

Embodiment 1

[0022] Example 1, see figure 1 , a novel electricity consumption information collection system based on TD-LTE wireless broadband, comprising a power communication control center 1 and a smart meter 7, characterized in that: an information control system 2, a TD -LTE communication system 3 , radio frequency processing device 4 , concentrator 5 and collector 6 . Wherein: the concentrator 5 is connected to at least one smart meter 7 through an RS485 or RS232 serial port, and collects user electricity consumption information recorded by the smart meter.

[0023] The collector 6 and at least one concentrator 5 perform data transmission through a broadband power carrier.

[0024] The radio frequency processing device 4 and at least one concentrator 5 perform data transmission through a TCP / IP local area network.

[0025] The radio frequency processing device 4 performs data transmission with the TD-LTE communication system 3 through the TD-LTE communication protocol.

[0026] Th...

Embodiment 2

[0028] Example 2, see image 3 The difference between this embodiment and Embodiment 1 is that the collection system of electricity consumption information data is different: the smart meter 7 directly transmits the recorded user electricity consumption information to The radio frequency processing device 4 does not go through the concentrator 5 and the collector 6. The rest of the processing is the same as in Example 1.

Embodiment 3

[0029] Example 3, see figure 2 , the radio frequency processing device 4 includes a radio frequency processing unit 401, an interface board 402, a signal processing unit 403, a memory 404, a protocol control unit 405 and a CPU 406, wherein: the radio frequency processing unit 401 receives the information of the TD-LTE communication system 3 and the concentrator 5 and Demodulate it, remove the carrier frequency through the interface board 402, and input the signal processing unit 403, the signal processing unit 403 will input the processed data into the memory 404 for buffering, and the CPU 406 will process the data in the memory 404, and the processed data After passing through the memory 404, it is coded and processed by the signal processing unit 403, and then sent to the TD-LTE communication system 3 and the concentrator 5 by the radio frequency processing unit 401 via the interface board 402.

[0030] In the scheme of the present invention, TD-LTE frequency can utilize 18...

Abstract

The invention discloses a novel power utilization information collection system based on TD-LTE (time division-long term evolution) wireless broadband. The system comprises a power communication control center, an intelligent ammeter, an information control system, a TD-LTE communication system, a radio-frequency processing device, a concentrator and a collector. The system disclosed by the invention adopts the TD-LTE technology and can adopt a flexible uplink/downlink configuration scheme in which the down peak rate can reach 80M and the up peak rate can reach 20M, and can provide a 64-Kbps full-duplex channel. Due to the adoption of a flat network architecture, the characteristics of high-speed data transmission, short system response time and high safety can be ensured.

Description

technical field [0001] The present invention relates to a technology for collecting power consumption information in a power system, in particular to a novel power consumption information collection system based on TD-LTE wireless broadband. Background technique [0002] At present, the State Grid Corporation of China has proposed the concept of smart grid. The construction of smart grid requires the characteristics of large capacity, high speed, multi-service and self-healing function of the power consumption information collection system, which puts forward new requirements for the power consumption information collection system. requirements; the power consumption information collection system can be divided into two parts, the backbone layer and the access layer. The current communication methods of the access layer mainly use industrial Ethernet, power line carrier, wireless communication network, etc.; industrial Ethernet is an active device, Does not have multi-point ...
