Description

Technical Field

[0001] This application relates to the technical field of power metering, and in particular, to a Beidou short message data hot standby device and method. Background Art

[0002] Currently, technologies such as medium-voltage power line carrier communication and Beidou short message communication are vigorously promoted in the power grid system to solve data communication problems in signal blind areas of the power grid and under emergency conditions. In the field of power metering, the Beidou short message communication technology is currently widely used to solve the problem of uploading power metering data. Compared with the medium-voltage power line carrier technology, the Beidou short message communication technology has greater advantages such as live installation, small communication interference, low cost, and small space-air communication delay, and is becoming more and more suitable for the electricity metering and centralized meter reading scenarios in remote areas, mountainous areas, and areas with frequent natural disasters in China. The power metering and centralized meter reading system based on the Beidou short message technology usually consists of: a Beidou power metering terminal at the field end and a Beidou power metering front-end server located at the master station end.

[0003] However, the current technical solutions of Beidou front-end servers have the following disadvantages in terms of reliability: 1) Since Beidou short message communication belongs to narrowband communication and the communication frequency is limited by the transmission frequency of the Beidou card, the error correction redundancy during communication is low, resulting in a low single communication success rate; 2) Currently, most of the Beidou short message access gateway units in Beidou front-end servers adopt a single-channel command machine mode. When the single communication success rate is low, the data processing in the Beidou power metering data processing unit cannot effectively restore the power metering data returned from the field terminal; 3) Since the single-frame data length of Beidou short message communication is shorter than the power metering data length, the power data must be transmitted in frames during transmission and then frame combination processing is performed in the front-end server. When frame combination cannot be performed due to the above reasons, the entire metering report data will be lost, resulting in the loss of the entire metering data. Summary of the Invention

[0034] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0035] Please refer to Figure 1 and 2 A Beidou short message data hot standby device provided in an embodiment of this application includes: a Beidou short message gateway composed of a plurality of array antenna receiving sub-units and a Beidou short message signal processing sub-unit, and a Beidou power metering data processing unit;

[0036] It can be understood that this application uses an array-type Beidou front-end server to replace the existing Beidou front-end server based on Beidou commander technology.

[0037] Among them, several array antenna receiving sub-units are in a one-to-one pairing relationship, forming several paired receiving sub-units. One receiving sub-unit in the paired receiving sub-unit uses a physical entity card, and the other receiving sub-unit uses a mapping card of the physical entity card. The mapping card is used to receive Beidou short message signals; and the card numbers of the Beidou short message cards of the two receiving sub-units in the paired receiving sub-unit are the same;

[0038] It should be noted that as Figure 2 shown, the array receiving sub-units satisfy the one-to-one pairing relationship, that is, receiving sub-unit 1 and receiving sub-unit 2 are paired, and receiving sub-unit 3 and receiving sub-unit 4 are paired; the card numbers of the Beidou short message cards used in the receiving sub-units are the same. One of the receiving sub-units uses a physical entity card, while the other receiving sub-unit uses a mapping card of the physical entity card. At the same time, the mapping card can only be used for data reception and cannot be used for data transmission.

[0039] The Beidou short message signal processing sub-unit is used to perform restoration processing on the Beidou short message signal to obtain the original power measurement data. Among them, the Beidou short message signal is the power measurement data uploaded by the Beidou power measurement terminal to the Beidou satellite navigation system;

[0040] It should be noted that the Beidou short message signal processing sub-unit completes signal parsing, source decryption, data error tolerance processing, data framing processing, etc. on the received Beidou short message signal until the original power measurement data sent from the field terminal to the power measurement master station is restored.

[0041] The Beidou power measurement data processing unit is used to make the original power measurement data compliant with the power measurement communication protocol, so that the compliant power measurement data meets the standardized requirements for power grid power measurement data transmission.

[0042] It should be noted that the Beidou power data processing unit completes the compliance of the original power measurement data transmitted by the Beidou short message signal processing sub-unit with the power measurement communication protocol, so that it meets the standardized requirements for power grid power measurement data transmission, so as to realize the data reporting from the power terminal to the power master station.

[0043] The above process is the data processing process of the on-site power measurement data reported to the power measurement master station (i.e., the uplink communication link). Further, for the relevant measurement instructions issued by the measurement master station, the Beidou power measurement data processing unit uploads the compliant power measurement data to the power measurement master station.

[0044] It should be noted that the mapping card in the paired sub-unit cannot participate in the data transmission process.

[0045] The above is a Beidou short message data hot standby device provided in an embodiment of the present application, and the following is a Beidou short message data hot standby method provided in an embodiment of the present application.

[0046] See also Figure 3 , a Beidou short message data hot standby method provided in an embodiment of the present application includes:

[0047] Step 101: A first receiving subunit and a second receiving subunit in a paired receiving subunit receive power metering data respectively;

[0048] It should be noted that if Figure 1 and 2 As shown, since the Beidou cards of the first receiving subunit (array antenna receiving subunit 1) and the second receiving subunit (array antenna receiving subunit 2) are mutually mapped cards, the addresses of the two cards are the same address, so the power data signal reported by the Beidou power metering terminal can be received at the same time.

[0049] Furthermore, the two receiving sub-units respectively parse the received power data signals and send them to the signal processing sub-unit for decryption and fault-tolerant processing.

[0050] Step 102: compare the power metering data of the first receiving subunit with the power metering data of the second receiving subunit to analyze whether the two power metering data meet the frame combination requirement;

[0051] It is understandable that the frame data comparison analysis is then performed to determine the reliability of the framing of the two data signals. If both cannot meet the framing requirements, step 104 is executed to start the supplementary call process; otherwise, step 103 is executed to start the framing program to form the original metering data packet.

[0052] Step 103: When the frame combination requirement is met, the power metering data is restored to obtain the original power metering data, and the original power metering data is compliantly processed so that the compliant power metering data meets the standardization requirements of power grid power metering data transmission;

[0053] It should be noted that when the frame integration requirements are met, the protocol processing of the power metering data packet is completed so that it can meet the power transmission protocol requirements of the power grid, so as to upload the data to the power metering master station legally and compliantly.

[0054] Step 104: When the frame combination requirement is not met, the data supplementary call processing flow is started.

[0055] In one embodiment, after the compliance processing of the original power metering data is completed, the power metering data after compliance processing is saved to the database in the Beidou front-end server; and after responding to the instruction of the power metering master station, the power metering data in the database is uploaded to the power metering master station.

[0056] Furthermore, in the embodiment of the present application, a Beidou short message data hot standby device is also provided, and the device includes a processor and a memory:
