The network 120 is used as a medium to provide a communication link between the energy storage device 110 and the data receiving end 130. The network 120 may include one or more connection types of subnetworks (i.e., first subnetwork, second subnetwork … …, nth subnetwork in the figures), such as wired, wireless communication links, or fiber optic cables, etc., wherein the network supports at least 3G/4G/5G, etc., mobile network connections. The energy storage equipment can be an energy storage system such as an optical storage and charging integrated machine, the energy storage equipment comprises a first physical layer data transmission link and a second physical layer data transmission link … … Nth physical layer data transmission link, and the physical layer data transmission links in the energy storage equipment are in one-to-one correspondence with the communication modes of the sub-networks in the network. And a link switching device is also arranged in the energy storage equipment so as to facilitate the switching requirement of the subsequent physical layer data transmission link.
It should be noted that, the method for transmitting data of the energy storage system provided by the embodiment of the application is generally executed by the energy storage system. The energy storage system comprises, but is not limited to, an optical storage and charging integrated machine and the like.
It should be understood that the number of energy storage devices, data receiving ends in fig. 1 is merely illustrative. Any number of energy storage devices, networks, and data receiving ends may be provided, as desired for implementation.
Referring to fig. 2, fig. 2 is a schematic flow chart of a data transmission method of an energy storage system according to an embodiment of the application, which includes the following steps:
step S210, data transmission parameters of at least two physical layer data transmission links in the data to be transmitted and the energy storage system are obtained.
The data transmission parameters comprise network transmission response speed, network packet loss rate, network transmission speed and overrun cost, and the communication modes of at least two physical layer data transmission links are different.
The method can be used in an energy storage system provided with at least two physical layer data transmission links, the communication modes of the at least two physical layer data transmission links in the energy storage system are different, and if the energy storage system is only provided with the two physical layer data transmission links, the communication modes of the two physical layer data transmission links are different, wherein the communication modes include at least two of wire, wireless, 4G and the like. The manner of traffic may also be required to be different for each physical layer data transfer link in the energy storage system.
The data to be transmitted is data generated based on equipment operation instructions, state data and abnormal data in the energy storage system, the data to be transmitted can be split into a plurality of sub-data packets to be transmitted, and the sub-data packets to be transmitted can be transmitted through a physical layer data transmission link respectively. At this time, the energy storage system may monitor the data transmission parameters of the physical layer data transmission link to be selected, and further select one or more of the physical layer data transmission links as a target transmission link, and transmit the data to be transmitted to the cloud (i.e., the data receiving end in fig. 1) through the target transmission link.
The data to be transmitted can also be data which needs to be issued to the energy storage system by the cloud, and similarly, the data to be transmitted can be split into a plurality of sub-data packets to be transmitted, and the sub-data packets to be transmitted can be transmitted respectively through a physical layer data transmission link. At this time, once the energy storage system receives the instruction issued by the data or the energy storage system is in a state of being able to receive the data, the energy storage system may monitor the data transmission parameters of the physical layer data transmission link to be selected therein, so as to select one or more of the physical layer data transmission links as a target transmission link, and transmit the data to be transmitted to the local (i.e., the energy storage device in fig. 1) through the target transmission link.
That is, the data to be transmitted may be data that needs to be sent to the energy storage system, and/or data that needs to be uploaded to the cloud end by the energy storage system.
The overrun fee may be determined by charging criteria corresponding to different physical layer data transmission links, including but not limited to the cost per data transmission unit (Mbyte) and the like. For example, for a mobile network, there may be a certain tariff package, if the current mobile network flow still belongs to the tariff package, the overrun may be marked as 0 or an amount set by a person skilled in the art, but if the current mobile network flow already belongs to the tariff package, the overrun may be determined according to the tariff standard of the tariff outside the mobile network package, and for a wireless network such as WiFi, the overrun may be set as 0 or an amount set by a person skilled in the art.
The network transmission response rate may be determined by replying from the sender request to the receiver to the sender, for example, the sender request may be sent to the receiver (such as the data receiver or the energy storage device in fig. 1) in advance through the sender (such as the energy storage device or the data receiver in fig. 1), and the receiver may feedback a feedback message to the sender based on the received sender request, so as to determine the network transmission response rate according to the time a of the sender request sent by the sender and the receiving time B of the feedback message received by the sender.
For example, the transmitting end (such as the energy storage device or the data receiving end in fig. 1) sends data to be transmitted to the receiving end (such as the data receiving end or the energy storage device in fig. 1) through the transmitting end (such as the energy storage device or the data receiving end in fig. 1), the receiving end feeds back a data receiving feedback message to the transmitting end based on the received data to be transmitted, and further determines the network packet loss rate according to the sending number of the data to be transmitted sent by the transmitting end and the receiving number of the data receiving feedback message received by the transmitting end.
The network transmission response rate, the network packet loss rate, and the network transmission speed may also be collected in a manner known to those skilled in the art.
Step S220, calculating the transmission coefficient of each physical layer data transmission link according to the network transmission response rate, the network packet loss rate, the network transmission speed and the overrun cost.
Because the counting mode of the network transmission response speed, the network transmission packet loss rate, the network transmission speed and the overrun expense in each physical layer data transmission link is realized based on the same counting logic, the data transmission capacity and the data transmission expense of each physical layer data transmission link can be evaluated in the four dimensions. For example, the four parameters may be summed to obtain the transmission system.
In an embodiment, since parameters of different dimensions may affect overall data transmission to different extents, or the current requirement for transmission efficiency is very high, but the requirement for cost is not very strict, a corresponding weight may be set for each parameter to adjust the extent of influence of each factor, and at this time, the transmission coefficient of each physical layer data transmission link is calculated according to the network transmission response rate, the network packet loss rate, the network transmission speed and the overrun cost, including: acquiring a preset network transmission response weight, a preset network packet loss weight, a preset network transmission speed weight and a preset cost weight of each physical layer data transmission link; and calculating the transmission coefficient of the physical layer data transmission link according to the network transmission response rate, the preset network transmission response weight, the network transmission packet loss rate, the preset network transmission packet loss weight, the network transmission speed, the preset network transmission speed weight, the overrun cost and the preset cost weight of the physical layer data transmission link to obtain the transmission coefficient of all the physical layer data transmission links.
In this embodiment, the transmission coefficient is determined in the following manner:
kx= (tx.1 x wx.1+tx.2 x wx.2+tx.3 x wx.3+tx.4 x wx.4)/(wx.1+wx.2+wx.3+wx.4) formula (1);
wherein Kx is a transmission coefficient of a physical layer data transmission link x, tx.1 is a network transmission response rate, wx.1 is a preset network transmission response weight, tx.2 is a network packet loss rate, wx.2 is a preset network packet loss weight, tx.3 is a network transmission speed, wx.3 is a preset network transmission speed weight, tx.4 is an overrun cost, and Wx.4 is a preset cost weight.
In this embodiment, obtaining a preset network transmission response weight, a preset network packet loss weight, a preset network transmission speed weight, and a preset cost weight of each physical layer data transmission link includes: acquiring a data importance level of data to be transmitted; and matching preset network transmission response weights, preset network packet loss weights, preset network transmission speed weights and preset cost weights of each physical layer data transmission link corresponding to the data to be transmitted according to the data importance level. In other words, the weights of the parameters are not constant, and different weight combinations can be configured according to the current importance level of the data to be transmitted, and the data can be selected as required. Therefore, the flexibility of the data transmission method can be further improved, and the requirements of users can be met more.
Step S230, prioritizing the physical layer data transmission links based on the transmission coefficients.
For example, the transmission coefficient size may be used as a priority ranking criterion, where the smaller the transmission coefficient, the higher the priority. Of course, the priority ranking may be ranked by a transmission coefficient and a preset priority of each physical layer data transmission link, and the preset priority may be further ranked based on a sequence of the preset priorities if there are at least two physical layer data transmission links with equal transmission coefficients. If the preset priority is not set, the physical layer data transmission links with the same transmission coefficient can be set to the same priority.
Step S240, selecting one or more physical layer data transmission links as target transmission links according to the order of priority order, and controlling the energy storage system to transmit the data to be transmitted through the target transmission links.
In an embodiment, selecting one or more physical layer data transmission links as the target transmission link in the prioritized order includes: acquiring a data importance level of data to be transmitted; and if the data importance level is greater than the preset importance level, taking the physical layer data transmission link of N before the priority order as a target transmission link, wherein N is greater than or equal to 2. The data importance level of the data to be transmitted may be preset based on the data source (which module generates the data), the data type (alarm data, device status data, device operation instructions, etc.) of the data to be transmitted, and the like. For the data to be transmitted with higher data importance level, a plurality of physical layer data transmission links can be selected for redundant transmission, so that the data to be transmitted can be successfully transmitted, and the network failure fault tolerance rate is increased. The data to be transmitted with the data importance level being greater than the preset importance level comprises, but is not limited to, fire alarm, equipment abnormality alarm, environment abnormality alarm, equipment operation instructions and the like. By adopting different numbers of target transmission links and selection criteria for different data importance levels, important data can be ensured not to be lost.
In an embodiment, after the energy storage system is controlled to transmit the data to be transmitted through the target transmission link, the method further includes: in the transmission process, acquiring new data transmission parameters of at least two physical layer data transmission links in an energy storage system; re-calculating new transmission coefficients of each physical layer data transmission link, and re-sequencing priorities and selecting new target transmission links; and if the new target transmission link is different from the target transmission link, controlling the energy storage system to switch the new target transmission link to transmit the data to be transmitted.
In other words, during a data transmission process of a piece of data to be transmitted, the target transmission link is not unchanged, and the current new target transmission link is determined according to the determination logic of the previous target transmission link again by monitoring the change condition of the data transmission parameter of each physical layer data transmission link in real time during the data transmission process, so that a possible condition is whether all new target transmission links or the previous target transmission links need not to be switched, or the original data transmission mode is maintained, but at least one of the target transmission links may be changed, for example, the original target transmission links are a 4G network and a wired network, and the new target transmission links are the wired network and WiFi, and the original 4G network needs to be replaced by the WiFi at this time, so that the link switching is performed. That is, the original target transmission link is compared with the new target transmission link, different physical layer data transmission links in the original target transmission link are used as the links to be switched, different physical layer data transmission links in the new target transmission link are used as the target switching links, and the target switching links are used for replacing the links to be switched.
In this embodiment, if the data to be transmitted is split into multiple sub-data to be transmitted, the timing of the link switching may be that after the link to be switched completes the transmission of the sub-data to be transmitted currently being transmitted, the target switching link performs the subsequent transmission of the sub-data to be transmitted.
In this embodiment, if there is only one data packet in the data to be transmitted, the transmission degree may be determined according to the transmission degree of the data packet, and the ratio of the size of the transmitted data to the size of the data packet is compared with a preset ratio to evaluate whether a handover link is necessary.
In this example, if there are multiple target transmission links, each target transmission link may transmit data to be transmitted separately, and perform redundant transmission, or a part of the target transmission links may transmit data to be transmitted separately, and another part (at least two) of the target transmission links jointly transmit data to be transmitted separately. For example, the data to be transmitted is split into a data packet a, a data packet B and a data packet C, the target transmission links are a link a, a link B and a link C, based on the preset transmission label of the data to be transmitted, at most two links are required to be completely transmitted, at this time, the link a with the highest priority can be selected to transmit the data packet a, the data packet B and the data packet C, the link B with the highest priority can be selected to transmit the data packet a and the data packet B, and the link C with the lowest priority can be selected to transmit the data packet C. As to how the receiving end performs the packetization after the data unpacking, this can be achieved in a manner known to those skilled in the art.
The number of target transmission links may be preset based on a data tag represented by at least one of a data type, a data source, and a data importance level of data to be transmitted. When there are multiple target transmission links, the data transmission mode of each target transmission link may be preset by a data tag represented by at least one of the data type, the data source and the data importance level of the data to be transmitted.
In this embodiment, if the target transmission link is one, the control energy storage system transmits the data to be transmitted through the target transmission link, including: acquiring a data transmission state of data to be transmitted; if the data transmission state is transmission failure, determining a physical layer data transmission link with a priority ordering sequence of one bit behind a target transmission link as a current transmission link, controlling the energy storage system to switch from the target transmission link to the current transmission link to transmit data to be transmitted until a preset stop condition is reached, wherein the preset stop condition comprises at least one of the following conditions, the data to be transmitted is successfully transmitted, and all physical layer data transmission links transmit the data to be transmitted.
Sometimes, there may be an unknown problem in a certain target transmission link, resulting in failure of transmission of data to be transmitted, where one or more new target transmission links (one or more physical layer data transmission links with priorities ordered after the original target transmission link) may be reselected for replacement, and switching of the transmission links is performed to ensure that the data to be transmitted is transmitted as successfully as possible. If each physical layer data transmission link attempts to transmit data and fails, stopping the process, and feeding back the message of data transmission failure to the preset terminal. Of course, if the new target transmission link determined according to the original target transmission link determination rule and the current new data transmission parameter is changed, the new target transmission link may be directly used as the current transmission link. Otherwise, if the new target transmission link determined according to the original target transmission link determining rule and the current new data transmission parameter is not changed, one or more physical layer data transmission links after the priority ordering can be selected as the current transmission link, and the number of the current transmission links can be consistent or inconsistent with the number of the previous target transmission links.
In an embodiment of the present invention, after the energy storage system is controlled to transmit the data to be transmitted through the target transmission link, the method further includes: if at least one first data transmission link to be selected exists, in the transmission process, the energy storage system is controlled to sequentially establish communication connection based on the at least one data transmission link to be selected according to the cost sequence, wherein the first data transmission link to be selected is a physical layer data transmission link with the overrun cost smaller than that of the target transmission link; each time the communication connection is established successfully, new data transmission parameters of a current transmission link are obtained, new transmission coefficients are determined, and the current transmission link is a first data transmission link to be selected corresponding to the current communication connection; if the new transmission coefficient is smaller than the transmission coefficient of the target transmission link, the energy storage system is controlled to be switched to the current transmission link to continue transmitting the data to be transmitted, and the energy storage system is stopped to sequentially establish communication connection with the data transmission links to be selected, which are not yet established with communication connection according to the cost sequence. That is, the cost of the target transmission link that may be currently selected is not the most economical, for commercial data transmission, the data amount may be relatively large, if the cost is relatively high, at this time, the physical layer data transmission links with the cost lower than the cost of the target transmission link can be found out by combing the cost of the target transmission links, the first data transmission links are ordered according to the cost, then the communication connection is attempted to be established based on the first data transmission links and the communication connection objects such as the cloud end (the communication connection is parallel to the communication connection of the current target transmission link and is not switched at this time), each time the establishment of the communication connection is successful, new data transmission parameters of the first data transmission link at this time are newly acquired once, new transmission coefficients of the first data transmission link at this time are recalculated based on the new data transmission parameters, the new transmission coefficients are compared with the transmission coefficients of the target transmission link, if the new transmission coefficients are smaller than the transmission coefficients of the target transmission link, the first data transmission link is further controlled to be switched to be the preferred data transmission link, and the first data transmission link can be continuously transmitted. This allows the cost of data transmission to be saved as much as possible.
In an embodiment of the present invention, after the energy storage system is controlled to transmit the data to be transmitted through the target transmission link, the method further includes: if the overrun cost of the target transmission link is greater than the minimum extremum, the energy storage system is controlled to establish communication connection based on a second to-be-selected data transmission link, wherein the second to-be-selected data transmission link is the minimum physical layer data transmission link of the overrun cost, and the minimum extremum is the minimum value of the overrun cost of each physical layer data transmission link; if the communication connection is established successfully, the energy storage system is controlled to switch to the second data transmission link to be selected to continue transmitting the data to be transmitted (continue transmitting the partial data which is not transmitted yet). If the overrun cost of the target transmission link is greater than the minimum extremum, it means that the target transmission link is not the link with the lowest cost, at this time, the link with the lower cost is often abnormal, and the connection is not caused, so the energy storage system can be controlled to establish a communication connection (parallel to the communication connection of the current target transmission link and not switched at this time) based on the second candidate data transmission link, and once the connection is successful, the energy storage system is switched to a new communication connection for data transmission, so that the cost is saved as much as possible.
In an embodiment of the present invention, if the minimum extremum is smaller than the preset minimum value, the energy storage system is controlled to establish communication connection based on the second data transmission link to be selected at the first time interval; and if the minimum extreme value is greater than or equal to the preset minimum value, controlling the energy storage system to establish communication connection based on the second data transmission link to be selected at intervals of a second time interval, wherein the second time interval is greater than the first time interval. If the minimum extremum is greater than or equal to the preset minimum value, at this time, all links may need additional cost, so that the switching of the links is relatively less urgent, and the connection attempt can be performed at a longer interval, but if the minimum extremum is less than the preset minimum value, a free or low-cost transmission link exists, and the connection attempt can be performed at a shorter interval, so that the cost of data transmission is reduced as soon as possible.
In an embodiment of the present invention, after the energy storage system is controlled to transmit the data to be transmitted through the target transmission link, the method further includes: if the target transmission link is one, re-acquiring the secondary selection data transmission parameters of the secondary selection data transmission link in the energy storage system in the transmission process, wherein the secondary selection data transmission link is a physical layer data transmission link with priority order one bit behind the target transmission link; and re-calculating the secondary selection transmission coefficient of the secondary selection data transmission link, and if the secondary selection transmission coefficient is smaller than the transmission coefficient of the target transmission link, controlling the energy storage system to switch to the secondary selection data transmission link to continue transmitting the data to be transmitted. In other words, the transmission coefficients of all the physical layer data transmission links do not need to be monitored and recalculated, so that more calculation force is likely to be consumed, whether the transmission coefficients of the physical layer data transmission links ranked at the back have larger change can be only seen, once the transmission coefficients of the physical layer data transmission links are smaller than the originally calculated transmission coefficients of the target transmission links, the physical layer data transmission links can be switched, on one hand, the calculation force is saved, and on the other hand, the possibility that the currently used physical layer data transmission links are optimal is further improved. In order to ensure the stability of the communication link as much as possible, under the communication scene, the physical layer communication link is switched by adopting a plurality of communication modes, thereby ensuring that important information is reported to the cloud in time. Wherein, the important information includes, but is not limited to, fire alarm, equipment abnormality alarm, environment abnormality alarm, equipment operation instruction, etc. Taking an energy storage system as a complete machine device as an example, the complete machine device adopts three networking interconnection modes, and the network failure fault tolerance rate is increased. The whole machine adopts a network checking strategy, and selects an optimal link for network interconnection. Under a special necessary scene, the important data is uploaded by simultaneously enabling three networking modes, so that the data is ensured not to be lost. Referring to fig. 3, fig. 3 is a specific flow chart of a data transmission method of an energy storage system according to an embodiment of the present invention, as shown in fig. 3, in a normal service flow, in which in a time T, a communication manner 1 is a wired network, a communication manner 2 is a wireless network, a communication manner 3 is a mobile network, for example, a network transmission response rate T1.1 of the wired network is calculated, a weight value is set to W1.1, a network packet loss rate T1.2 of the wired network is calculated, a weight value is set to W1.2, a network transmission rate T1.3 of the wired network is calculated, a weight value is set to W1.3, an overrun fee T1.4 of the wired network is calculated, a weight value is set to W1.4, a network transmission response rate T2.1 of the wireless network is calculated, a weight value is set to W2.1, a network packet loss rate T2.2 of the wireless network is calculated, and a weight value is set to W2.2, calculating a network transmission speed T2.3 of the wireless network, setting a weight value of the network transmission speed T2.3 as W2.3, calculating an overrun cost T2.4 of the wireless network, setting a weight value of the network transmission speed T2.4 as W2.4, calculating a network transmission response speed T3.1 of the mobile network, setting a weight value of the network transmission speed T3.1 as W3.1, calculating a network packet loss rate T3.2 of the mobile network, setting a weight value of the network transmission speed T3.3 of the mobile network as W3.2, calculating an overrun cost T3.4 of the mobile network as W3.4, calculating a network weighted average value of three kinds of communication in the initial operation of the equipment to obtain transmission coefficients K1, K2 and K3, wherein a specific calculation mode can refer to x in the formula (1) as values 1, 2 and 3 respectively, selecting a minimum Kx value link as a default link, and continuously calculating Kx value in a service flow, and switching the links when the Kx value is larger than the minimum Kx value of other links. And setting a highest allowable usage weight value. Meanwhile, after each link weight is determined for the first time and the main link has been selected, comparing the link corresponding to the lower value of the cost weight (overrun cost) with the main link overrun cost weight (overrun cost) of the main link being used according to the network overrun cost weight (overrun cost), performing link switching attempt, and recalculated the link selection weight (transmission coefficient), for example, the wired network overrun cost weight is 0, the wireless network overrun cost weight is 1, the mobile network overrun cost weight is 2, when the main link is 4G network and the network can be connected normally, the second link is opened at regular time to try the wired network in sequence, the wireless network is switched to the wired network if the first attempt of the wired network succeeds and the link weight is lower than the mobile network weight.
Still further, it is assumed that when the primary link is a wireless network and can be normally connected to the internet, the second link is enabled to continuously try the wired network because the wired overrun cost is 0, and (if the wired network overrun cost is not zero and is lower than the wireless network, the wired network is periodically tried), and the mobile network overrun cost weight is high (overrun cost) for the wireless network and the wired network, so that the mobile network will not be tried to be connected.
In an embodiment, the highest allowable usage weight value (weight extremum) for each parameter and/or the weight sum value for all parameters may be preset.
Referring to fig. 4, fig. 4 is a schematic flow chart of another specific method for transmitting data in the energy storage system according to the embodiment of the present invention, as shown in fig. 4, in a necessary scenario (where the data importance level is greater than the preset importance level), data needs to be stably transmitted to the cloud end, if the physical layer data transmission link of the energy storage system is wired, wireless, and 4G, the data is uploaded sequentially through the wired, wireless, and 4G until the data is successfully uploaded. Namely, the data to be transmitted with the data importance level larger than the preset importance level is regarded as important uploading data, the important uploading data line is uploaded through a wire, if the uploading is successful, the process is ended, if the uploading is failed, the wireless uploading is ended, if the uploading is successful, the process is ended through 4G uploading, if the uploading is failed, the process is ended, if the uploading is successful, the process can be ended or the first step is returned again, and the circulation of the steps is carried out through the wire uploading again. To prevent unnecessary loops, a limit on the number of loops may be set, and if the limit is exceeded, the overall flow is stopped. It should be noted that this embodiment is only an example, and the selection order of the specific links may be selected by those skilled in the art as needed.
Aiming at the problem that in the integrated machine, in order to ensure the stability of a communication link as much as possible in a single communication scene when uploading and downloading important information, but under the condition of the means, such as the situation that a physical link layer is damaged and the loss of a link is unavoidable, the method provided by the embodiment of the invention further ensures the stability of the communication link and improves the reliability of data transmission by collecting data transmission parameters of at least two physical layer data transmission links in an energy storage system configured with at least two communication modes, calculating the transmission system, performing priority ordering, selecting one or more physical layer data transmission links as a target transmission link based on the priority order, and transmitting the data to be transmitted by configuring multiple communication modes in the energy storage system.
In the data transmission process, the transmission system of each physical layer data transmission link is continuously updated, the priority ordering is refreshed, the target transmission link is adjusted based on the change of the priority order, and the target transmission link is switched, so that the data transmission is always kept through more excellent links in the data transmission process, the data transmission speed and efficiency can be improved, the resource waste is reduced, and the reliability of the data transmission is further improved.
Through configuring the corresponding weight for the data transmission parameters, the preference of the current link selection can be adjusted by adjusting the weight, for example, the stability and the speed of retransmission can be improved, the weight of the network transmission response speed, the network packet loss rate and the network transmission speed can be set larger, the weight of the overrun fee can be set larger, or the balance of the fee and the stable transmission can be taken, so that the overall target transmission link selection is more diversified, the requirements of users are met, and the customer experience is improved.
The data to be transmitted is important, that is, the data importance level is greater than the preset importance level, at least two links can be selected or all physical layer data transmission links can be adopted for redundant transmission, so that the reliability of data transmission is further ensured.
