Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a wireless communication system and method based on Lora omnidirectional transparent transmission. Background Art

[0002] Power distribution network automation requires the support of communication protocols. In 10kV distribution networks, the power IEC 60870-5-101 / 104 (hereinafter referred to as 101 / 104 protocol) protocol is often used for communication between the dispatching center and the substation or terminal; 101 protocol serial communication can also be used in UDP mode, and 104 protocol is used for network communication in TCP / IP mode.

[0003] Although the mobile network is well-developed at present, there are still a few areas that cannot be covered by the mobile network. The distribution network automation equipment in these areas will find it difficult to obtain reliable communication support.

[0004] There are currently several solutions to the communication problem of distribution automation equipment in areas without mobile network coverage, but they all have disadvantages that cannot be ignored:

[0005] 1. Use power carrier multi-communication data relay transmission, but there are still some problems to be solved when this solution is applied to 10kV distribution network: the first is that the signal coupling equipment of medium-voltage power carrier is very expensive; the second is that the installation and construction of medium-voltage power carrier is difficult (it is necessary to shut down the line for construction, and the construction cost is expensive); the third is that the reliable transmission distance of medium-voltage power carrier is not enough, and it is limited by the status of medium-voltage line circuit breaker (when the circuit breaker in the line is open, the power carrier signal will be interrupted);

[0006] 2. Build a dedicated power network base station or a phased array antenna array base station to transmit data in a centralized manner. However, this solution is not economically suitable for the scenario set here. The reasons are as follows: the distribution network line passes through areas without operator signal coverage. The distribution network equipment that needs to communicate is widely distributed, small in number, and not concentrated. The construction cost of a dedicated power network base station or a phased array antenna base station is often expensive and its energy consumption is extremely high. It is necessary to build its power supply facilities separately. It is suitable for scenarios where communication terminals are concentrated. Therefore, building a dedicated power network base station or a phased array antenna array base station to transmit data in a centralized manner is not suitable for the scenario set here.

[0007] This patent needs to solve the communication problem of distribution automation equipment in the above areas without mobile network coverage, which are as follows:

[0008] 1. Solve the problem of reliable data transmission in the complex and changeable spatial environment of mountainous areas. The propagation of radio signals in the air is affected by many factors, resulting in unstable transmission or transmission interruption. The main factors are weather factors: such as rainy days, foggy days, etc., and natural terrain environment: such as urban buildings, forest trees, mountains, etc., which will have a great impact on the propagation of radio waves, resulting in unstable transmission or transmission interruption.

[0009] 2. Solve the problem of construction convenience in existing communication solutions for areas without mobile networks. The construction of power carrier communication is too complicated, especially medium-voltage power carrier communication, which requires power outages or the use of electrified vehicles, which poses a great risk. The construction of power-dedicated network base stations or phased array antennas cannot be completed in a short time, and the construction period is too long.

[0010] Among them, the Lora wireless network has the advantages of low power consumption, strong long-distance communication capability, strong anti-interference ability, anti-multipath effect, anti-Doppler characteristics, easy deployment and low cost. These advantages make the Lora wireless network very suitable for distribution network power communication scenarios that require low power consumption, long communication distance, strong anti-interference ability, shielded environment (strong diffraction ability) and low cost.

[0011] However, the 350MHz to 510MHz Lora wireless network belongs to the narrowband Internet of Things technology, and its communication rate is extremely low, only 11kbps to 100kbps. This low transmission rate feature is not suitable for transmitting any protocol based on TCP / IP, because the TCP / IP protocol packet header and tail will consume a lot of bandwidth resources, resulting in serious packet loss in data transmission.

[0022] As a preferred solution of the Lora omnidirectional transparent wireless communication system based on the present invention, the IEC104 protocol extraction and TCP / IP protocol packet unit of the second communication module will package the IEC104 protocol data frame received from the Lora wireless unit layer by layer according to the TCP / IP protocol packet rules and send it to the distribution module connected to the network cable.

[0037] Specifically, the transmitter 200 and the receiver 300 are both connected to the relay 100 by wireless signals, and transmit signals over long distances through the relay 100. The transmitter 200 is located in an area covered by a mobile network, and the receiver 300 is located in an area not covered by a mobile network; when data is downlinking, the master station data transmitted by the transmitter 200 is transmitted to the receiver 300 via the relay 100; when data is uplinking, the reply data transmitted by the receiver 300 is transmitted to the transmitter 200 via the relay 100.

[0038] Background of this embodiment In rural areas, due to the vast geographical environment and sparse mobile network base stations, many areas may not have mobile network coverage.

This enables the system to communicate directly with the power distribution equipment, which can improve the efficiency and accuracy of data transmission.

[0047] Preferably, the relay terminal 100 includes a third communication module 101, and the third communication module 101 is provided with at least one. The third communication module 101 is used to transmit master station data or reply data, which can enhance the data processing capability of the system and ensure the effective transmission of data at the relay terminal.

[0048] Furthermore, the first communication module 202 and the second communication module 301 both include an IEC104 protocol extraction and TCP / IP protocol packet unit 202a, which is used to unpack the TCP / IP protocol frame received from the network cable to extract the IEC104 protocol data frame, thereby optimizing the data encapsulation and decapsulation process and improving the efficiency and reliability of data transmission.

[0049] Furthermore, the third communication module 101 includes a Lora wireless unit 101a; when data is downlink, the Lora wireless unit 101a receives the IEC104 protocol data frame extracted by the IEC104 protocol extraction and TCP / IP protocol packet unit 202a of the first communication module 202, and then transmits it to the IEC104 protocol extraction and TCP / IP protocol packet unit 202a of the second communication module 301, utilizing the low power consumption and long-distance communication capabilities of the Lora technology, which is suitable for the specific needs of power distribution network automation.

[0050] Furthermore, the IEC104 protocol extraction and TCP / IP protocol packet unit 202a of the second communication module 301 will package the IEC104 protocol data frame received from the Lora wireless unit 101a layer by layer according to the TCP / IP protocol packet rules and send it to the distribution module 302 connected to the network cable, ensuring the compatibility and transmission efficiency of the data in different network environments.
