[0002] With the development of energy storage technology, the installed capacity of energy storage power stations has been continuously expanded, and a large number of energy storage power stations of various types have been built and put into use. Energy storage power stations have potential risks such as aging of energy storage equipment, heat dissipation failure, and line failure, which can lead to various serious accidents such as fire, equipment damage, and high-voltage leakage. Therefore, safety monitoring of energy storage power stations is very important. It is necessary to collect the status data of energy storage power stations in real time, conduct safety monitoring of energy storage power stations, and ensure the safe operation of energy storage power stations.

[0003] However, energy storage power stations are often composed of hundreds of thousands or even more batteries. A 20MWH small energy storage power station can collect up to 40,000 signals in total. At a collection frequency of 1 second, the amount of raw data in one year is as high as 100GB. Traditional solutions use JSON format or KeyValue format to generate data packets. Such data packets have too large additional attribute identifiers, and the character encoding of the data itself will also take up a lot of space, causing high load problems on network transmission bandwidth, server storage, and access gateway processing.

[0053] The embodiment of the present application provides a data transmission system, method, device, equipment and storage medium for an energy storage power station. The transmission system of the embodiment of the present application includes: an energy storage power station system, an access gateway, a message server, a data receiving computer and a data server; wherein the energy storage power station system is used to obtain energy storage power station data; the access gateway is used to binary encode the energy storage power station data to obtain a data packet, and send the data packet to the message server; the message server is used to forward the data packet to the data receiving computer; the data receiving computer is used to decode the data packet to obtain the energy storage power station data, and write the energy storage power station data to the data server; the data server is used to store the energy storage power station data. The embodiment of the present application uses an efficient binary encoding method to encode the energy storage power station data through the access gateway. The volume of the data packet obtained after binary encoding is greatly reduced compared with the data packet volume of the prior art. Therefore, the present application can reduce the transmission network bandwidth, the load of the data receiving computer and the data server, and improve the transmission efficiency of the energy storage power station data.

[0054] Next, a data transmission system for an energy storage power station provided in an embodiment of the present application is described in detail. The transmission system may include: an energy storage power station system, an access gateway, a message server, a data receiving computer, and a data server;

[0055] Wherein, the energy storage power station system is used to obtain energy storage power station data;

[0056] The access gateway is used to binary encode the energy storage power station data to obtain a data packet, and send the data packet to the message server;

[0057] The message server is used to forward the data packet to the data receiving computer;

[0058] The data receiving computer is used to decode the data packet to obtain the energy storage power station data, and write the energy storage power station data to the data server;

[0059] The data server is used to store the energy storage power station data.

[0060] Specifically, the energy storage power station system and the access gateway can be set up in the energy storage power station, the message server, the data receiving computer and the data server can serve as a cloud platform, the access gateway and the cloud platform can be connected through a network, and the various devices in the cloud platform can be connected through a data bus.

[0061] As a further implementation, the energy storage power station system includes a data acquisition computer and a data publishing computer;

[0062] Wherein, the data acquisition computer is used to collect the energy storage power station data;

[0063] The data publishing computer is used to publish the energy storage power station data to the access gateway.

[0064] Specifically, the data acquisition computer can obtain the status data of the energy storage power station as the energy storage power station data through various sensors or monitoring equipment, and then the data publishing computer can publish the collected energy storage power station to the access gateway, and the access gateway can also obtain the energy storage power station data from the data publishing computer.

[0065] As a further optional implementation, the energy storage power station system is used to obtain at least one of telemetry data, telesignaling data and telepulse data of the energy storage power station as the energy storage power station data.

[0066] As a further optional embodiment, refer to Figure 1 , This embodiment provides an optional structural diagram of an energy storage power station data transmission system, wherein the message server adopts an MQTT server;

[0067] The MQTT server is used to:

[0068] Receiving a publishing request for the MQTT topic of the access gateway to obtain the data packet from the access gateway;

[0069] A subscription request for the MQTT topic from the data receiving computer is received to send the data packet to the data receiving computer.

[0070] Specifically, the energy storage power station access gateway (ie, access gateway) can obtain energy storage power station data from the energy storage power station system, binary encode the energy storage power station data to obtain a data packet, and then send the data packet to the MQTT server through the MQTTS protocol.

[0071] The MQTT server may implement a server of the MQTTS protocol, process a topic publishing request of a first MQTTS client (eg, an access gateway), and process a topic subscription request of a second MQTTS client (eg, a data receiving computer).

[0072] The energy storage power station data receiving computer (i.e., data receiving computer) can subscribe to the MQTT topic, receive the data packets pushed by the access gateway, then perform binary decoding on the data packets, and then write the decoded energy storage power station data to the data server.

[0073] The data server can store the power plant data, such as the telemetry data, telesignaling data and telepulse data obtained after decoding.

[0074] As a further optional implementation, the access gateway is used to periodically obtain the energy storage power station data from the energy storage power station system according to a preset time window, encapsulate the energy storage power station data into a full data packet in a binary encoding format, and send the full data packet to the message server;

[0075] Alternatively, the access gateway is used to receive the displacement data generated by the energy storage power station in real time within the preset time window, encapsulate the displacement data into an incremental data packet in a binary encoding format at each preset time interval, and send the incremental data packet to the message server.

[0076] Specifically, the data packet obtained by binary encoding may include a full data packet and an incremental data packet. The full data packet may include all telemetry data, telesignal data, and telepulse data of the energy storage power station, and is a snapshot of the current state of the energy storage power station. The incremental data packet may be a collection of energy storage power station data that has changed within a preset time interval. The energy storage power station data that has not changed may not appear in the incremental data packet, thereby greatly reducing the amount of data sent. Exemplarily, Figure 2 A schematic diagram of data included in a full data packet provided in this embodiment, Figure 3 A schematic diagram of data included in an incremental data packet provided in this embodiment.

[0077] This embodiment can provide a method for transmitting energy storage power station data based on binary coding. In order to ensure that the bandwidth and capacity required for transmission and storage of energy storage power station data are as small as possible and to improve the reliability and security of transmitting energy storage power station data, this embodiment can adopt the following implementation methods:

[0078] Full data packet collection and sending stage: The access gateway periodically obtains all telemetry data, telesignal data and telepulse data from the energy storage power station system as energy storage power station data according to the preset time window, encapsulates the energy storage power station data into a full data packet in a binary fixed encoding format, and then sends it to the MQTT server through the MQTT protocol.

[0079] Incremental data packet processing stage: within the above-mentioned preset time window, the access gateway receives the displacement data generated by the energy storage power station in real time, and encapsulates the newly generated telemetry data, telesignal data and telepulse data (i.e. displacement data) in a binary fixed encoding format as an incremental data packet every preset time interval (e.g. 1 second), and sends it to the MQTT server through the MQTTS protocol.

[0080] For example, when the network connection is normal and the device (the device mentioned in the embodiment of the present application may refer to each device, system or apparatus in the energy storage power station data transmission system) is working normally, the flow chart of the access gateway sending a full packet (i.e., a full data packet) to the MQTT server can be referred to as follows: Figure 4 , the flow chart of MQTT server receiving data packets can be referred to Figure 5 .

[0081] Considering that there may be a situation where the data packet transmission fails due to network anomalies or equipment failures, the embodiment of the present application may further include:

[0082] The message server adopts MQTT server;

[0083] The access gateway is further used to store the full data packet and the incremental data packet that failed to be sent in a local cache queue; after the failure is recovered, the full data packet and the incremental data packet that failed to be sent are taken out from the local cache queue, and sent to the breakpoint resume topic of the MQTT server;

[0084] The data receiving computer is also used to subscribe to the breakpoint resume topic; receive the full data packet and the incremental data packet through the breakpoint resume topic and decode them, and then write the decoded energy storage power station data to the data server.

[0085] Specifically, the processing process of failed data packets and the processing process of breakpoint resumption can specifically include: when the access gateway detects that the data packet sending fails, the data packet that was not successfully sent can be cached, and the breakpoint resumption process can be started after the fault is recovered, and the cached data packet can be resent to the MQTT server through the breakpoint resumption topic.

[0086] The access gateway can save the full data packets and incremental data packets that failed to be sent through the local cache queue. After the fault is recovered, the access gateway can take out the data packets one by one from the local cache queue and send the data packets to the breakpoint-resume topic of the MQTT server without re-encoding; the data receiving computer can subscribe to the breakpoint-resume topic, and then decode the data packets received through the breakpoint-resume topic and save them to the data server.

[0087] The breakpoint-resume transmission mechanism of this embodiment can ensure that data integrity is maintained even in the event of abnormal data packet transmission. The MQTTS protocol ensures the security of channel communication, effectively handles abnormal situations such as data packet loss and loss, and improves the security and reliability of data transmission in energy storage power stations.

[0088] For example, when the network connection is abnormal or the device fails, the flow diagram of the access gateway sending a data packet to the MQTT server can be referred to Figure 6 , the flow chart of MQTT server receiving data packets can be referred to Figure 7 .

[0089] The embodiments of the present application may have the following beneficial effects:

[0090] (1) The energy storage power station data is encoded in binary and arranged in the order of the point table of the energy storage power station data, without the need for additional identification or auxiliary description attributes, thus saving space;

[0091] (2) A protocol combining full data packets and incremental data packets is used. The incremental data packets only need to contain the changed energy storage power station data, which greatly saves the amount of data that needs to be transmitted;

[0092] (3) The breakpoint-resume protocol solves the problem of data loss in the event of network anomalies or device failures;

[0093] (4) Through the MQTTS protocol, the communication is encrypted using the SSL certificate to ensure the security of data transmission in the energy storage power station;

[0094] (5) The energy storage power station data transmission system of the present application can be applied to various types of energy storage power stations to achieve efficient and secure transmission and storage of energy storage power station data.

[0095] Next, the solution of the embodiment of the present application will be described in detail and explained in conjunction with specific application examples:

[0096] Specifically, the full data packet can be an array in binary format, which may include a header, data length, telemetry data, telesignal data, telepulse data, etc. The header of the full data packet is 1 byte, and 0x00 is taken to represent the full data packet. The amount of telesignal data, telemetry data, and telepulse data represent the total number of each type of data, represented by a 2-byte unsigned integer. The data generation time is accurate to milliseconds and is represented by an 8-byte unsigned integer. Each telemetry data item is a floating point number occupying 4 bytes and is arranged in the order of the energy storage power station table. The telesignal data is arranged in the order of the energy storage power station table. Each data occupies one bit in the byte. 1 represents that the data is True, and 0 represents that the data is False. The data is arranged in order from high to low in the byte. For the last few data, if it is less than 8, the other bits are 0. The telepulse data item is a signed integer occupying 4 bytes and is arranged in the order of the point table.

[0097] The incremental data packet can be an array in binary format, which may include a header, data length, telemetry change data, telesignal change data, telepulse change data, etc. The header of the incremental data packet is 1 byte, and 0x01 is taken to represent the incremental data packet. The full data packet identifier is 8 bytes, which is used to identify the full data packet to which this incremental data packet belongs. The packet sequence number is the sequence number of the incremental data packet, which occupies 2 bytes, starts from 0, and represents the sequence number of the incremental data packet within the full time window (i.e., the preset time window). The data generation time is the generation time of the current incremental data packet, which is a timestamp of 8 bytes. The telemetry change data first has a total number of telemetry change items, which is a 2-byte unsigned integer representing the number of telemetry data items in this incremental data packet. Each telemetry change data consists of a point table sequence number, a collection time, and a data item value. The point table sequence number is the order of the telemetry data in the energy storage power station table, which is an unsigned integer of 2 bytes. The acquisition time is a 2-byte signed integer, which is the offset in milliseconds of the data item relative to the data generation time of the incremental data packet. The data item value is a 4-byte floating point number. The telemetering change data first has a total number of telemetering change items, which is a 2-byte unsigned integer representing the number of telemetering data items in this incremental data packet. Each telemetering change item consists of a point table number, acquisition time and data item value. The point table number is the order of the telemetering signal in the electric point table, which is an unsigned integer of 2 bytes. The acquisition time is a 2-byte signed integer, which is the offset in milliseconds of the data item relative to the data generation time of the incremental packet. The data item value is 1 byte, and the 7th bit is used to represent the signal value, 1 is True, 0 is False, and the other 7 bits are 0. The telemetering change data first has a total number of telemetering change items, which is a 2-byte unsigned integer representing the number of telemetering data items in this incremental data packet. Each telemetering change item consists of a point table number, acquisition time and data item value. The point table number is the order of the remote pulse signal in the electric point table, which is an unsigned integer of 2 bytes. The acquisition time is a signed integer of 2 bytes, which is the offset in milliseconds of the data item relative to the generation time of the incremental packet data. The data item value is a 4-byte signed integer.

[0098] The access gateway can periodically obtain all telemetry data, telesignal data, and telepulse data in the point table, and encapsulate them into full data packets, and then publish the full data packets to the normal topic of the MQTT server. The full time window can be set to 5 minutes, sending the first full data packet at 0:00:00, and the second full data packet at 0:05:00, and the full data packets are sent repeatedly. The receiving end (i.e., the data receiving computer) subscribes to the normal topic, decodes the received full data packet, and writes the decoded data to the data server.

[0099] The access gateway can send the received displacement data in the energy storage power station every 1 second within a full time window, encapsulate it into incremental data packets, and publish it to the normal topic of the MQTT server. The receiving end (i.e., the data receiving computer) subscribes to the normal topic, decodes the received incremental data packets, and writes the decoded data to the data server.

[0100] If data packets are sent abnormally, the access gateway can cache the data packets that failed to be sent successfully and initiate the breakpoint resume process after the fault is resolved.

[0101] The local cache queue of the access gateway can save the full data packets and incremental data packets that failed to be sent. After the fault is resolved, the access gateway takes out the data packets one by one without re-encoding and directly sends them to the breakpoint resume topic of the MQTT server. By subscribing to the breakpoint resume topic, the data receiving computer can receive and decode the retransmitted data packets, and then write the decoded data to the data server.

[0102] This embodiment can use binary coding to encode the energy storage power station data, which can greatly reduce the size of the data packet, thereby reducing the pressure on the network bandwidth, data receiving computers and data servers. At the same time, it can also ensure that the integrity of the energy storage power station data can be maintained in the event of abnormal data packet transmission through a breakpoint resume mechanism, and ensure the security of channel communication through the MQTTS protocol.

[0103] The embodiment of the present application also provides a method for data transmission of an energy storage power station, which relates to the field of Internet of Things communication technology. The transmission method provided in the embodiment of the present application can be applied to a terminal, can also be applied to a server, and can also be software running in a terminal or a server.

The server can also be a node server in a blockchain network; the software can be an application that implements the transmission method, etc., but is not limited to the above forms.
