Description

Background Art

[0002] With the vigorous development of the new energy industry, the cascade application of battery packs is becoming more and more important, which can improve the recycling efficiency of battery packs, optimize the cost of batteries and reduce the environmental pollution caused by the disassembly of battery packs. For example, there will be multiple battery packs in series and parallel in the battery PACK carried by new energy vehicles to meet the voltage and power requirements of new energy vehicles.

[0003] In order to reasonably allocate the time and cycle of communication detection, the commonly used method is: by setting the detection device end as the master node, setting each battery in the battery pack as a slave node, and setting a fixed communication cycle for each slave node. During this cycle, the slave node can communicate with the master node multiple times, so that the detection device end of the master node can determine the status of the battery pack of the slave node through communication information during the communication cycle, so that the battery pack forms an integrated structure.

[0004] However, the commonly used methods have the following technical problems: During the communication process, since the communication cycle of each slave node is still pre-set and the duration of the communication cycle is also fixed; if the communication quality of a slave node is good, it can complete the communication with the master node once, but it still needs to wait for the entire communication cycle to detect the next slave node; and if the communication quality of a slave node is poor, the slave node cannot complete the communication with the master node within the allocated communication cycle. At this time, there will be a problem that a slave node fails to communicate in this communication cycle, and the master node cannot get data. The whole process is not only inflexible, but also time-consuming, and the utilization rate of the time cycle is not high. Summary of the invention

[0088] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0089] In order to solve the above problems, a communication time slice allocation method, device, system, electronic device and computer-readable storage medium provided in an embodiment of the present application will be introduced and explained in detail through the following specific embodiments.

[0090] Reference Figure 1 , showing a flow chart of a method for allocating communication time slices provided by an embodiment of the present invention.

[0091] The method can be used for time slot allocation in a multi-node wireless communication system. The method involves a master node and N slave nodes that are interconnected in the wireless communication system. In each communication time period, each slave node is provided with I communication time slot, and each communication time slot communicates once.

[0092] Reference Figure 2-4 , respectively showing a schematic diagram of a wireless communication multi-node network provided by an embodiment of the present invention, a schematic diagram of a wireless communication network master-slave node communication provided by an embodiment of the present invention, and a schematic diagram of a wireless communication network slave node communication time slice provided by an embodiment of the present invention.

[0093] Specifically, it may involve one wireless communication master node and N wireless communication slave nodes. The slave node is a node of a battery in a battery pack, referred to as a slave node.

[0094] like Figure 3 , which is a schematic diagram of the communication between the master and slave nodes of the wireless communication network. The wireless communication network includes a master node and N slave nodes, where the value of N is at least 2. The N wireless communication slave nodes complete the wireless communication with the wireless communication master node in turn, and the above communication process is repeated periodically, thereby completing the communication of the entire wireless communication network.

[0095] like Figure 4 , each slave node is allocated I communication time slices, the master and slave nodes will complete a wireless communication within I communication time slices, each communication time slice can communicate once, a total of I times. Figure 4 For example, I can be 4.

[0096] Wherein, as an example, the method for allocating the communication time slice may include:

[0097] S11. Before the master node respectively performs wireless communication with the N slave nodes, a communication parameter value of each slave node is calculated, wherein the communication parameter value includes at least one of a signal strength value and a signal loss rate.

[0098] In one embodiment, in wireless communication, the communication quality of different nodes varies. In this case, the communication parameter value of each slave node can be determined first, and the communication quality of the slave node can be determined by the communication parameter value, and then the communication time slices of the slave node can be reallocated according to the communication quality. Under the condition that the wireless communication quality varies, the communication time slices of the slave nodes with better communication quality can be allocated to the slave nodes with poor communication quality, so that the slave nodes with poor quality have more time to connect with the master node.

[0099] Based on the current communication quality, wireless communication can be completed within a time slot less than the allocated time slot, which can improve the wireless communication efficiency of the system. At the same time, based on the current communication quality, the excess time slots of slave nodes with good communication quality can be allocated to slave nodes with poor communication quality, which can reasonably utilize communication resources and improve communication efficiency.

[0100] S12. Determine whether the communication parameter value is within a preset parameter range value, where the preset parameter range value includes at least one of a preset signal strength value and a preset signal loss rate.

[0101] In one embodiment, the communication parameter value may include a signal strength value and a signal loss rate. The signal strength value may be an RSSI value, which may also be called a receiving sensitivity, or in layman's terms, the received signal strength. The signal loss rate may be a per value, which may be the loss of the optical signal transmitted per unit length.

[0102] Different parameter range values ​​can be used for different communication parameter values, and then the number of communication time slices of each slave node is adjusted according to the comparison result between the communication parameter value and the parameter range value, so that the master node can communicate wirelessly with each slave node according to the adjusted number of communication time slices.

[0103] S13: If the communication parameter value is within the parameter range, the number of communication time slices of the slave node is not adjusted.

[0104] In one embodiment, if the communication parameter value is within the parameter range, for example, the signal strength value is within the corresponding preset parameter range, or the signal loss rate is within the corresponding preset parameter range, it indicates that the communication quality between the master node and the slave node is relatively stable, and the number of communication time slices of the slave node may not be adjusted.

[0105] S14: If the communication parameter value is not within the parameter range, adjust the number of communication time slices of the slave node.

[0106] In one embodiment, if the communication parameter value is not within the parameter range, for example, the signal strength value is not within the corresponding preset parameter range, or the signal loss rate is not within the corresponding preset parameter range. This indicates that the communication quality between the master node and the slave node may be relatively good or relatively poor. If it is relatively good, the number of communication time slices of the slave node can be appropriately reduced. On the contrary, if it is relatively poor, the number of communication time slices of the slave node can be appropriately increased.

[0107] Reference Figure 5 , shows an operation flow chart of adjusting the communication time slice according to the signal strength value provided by an embodiment of the present invention.

[0108] In one embodiment, the communication parameter value is: a signal strength value, and the parameter range value includes: a preset signal strength value.

[0109] In order to dynamically average the signal strength value, as an example, the adjusting the number of communication time slices of the slave node may include the following sub-steps:

[0110] S21. If the signal strength value is greater than a preset first strength value, a first strength adjustment quantity is calculated according to a preset first coefficient parameter and I, and the number of communication time slices of the slave node is reduced according to the first strength adjustment quantity.

[0111] S22. If the signal strength value is less than a preset second strength value, a second strength adjustment amount is calculated according to a preset second coefficient parameter and I, and the number of communication time slices of the slave node is increased according to the second strength adjustment amount.

[0112] The preset first intensity value is the maximum value of the intensity range, and the preset second intensity value is the minimum value of the intensity range.

[0113] The user can pre-set the first intensity value and the second intensity value, and the first intensity value and the second intensity value can be adjusted according to actual needs. The first intensity value is greater than the second intensity value, and the intensity range value can be obtained by setting the first intensity value and the second intensity value.

[0114] It can be determined whether the signal strength value is within the strength range. If the signal strength value is greater than the preset first strength value, it means that the communication quality of the slave node is good. The first strength adjustment quantity is calculated according to the preset first coefficient parameter and I, and the number of communication time slices of the slave node is reduced according to the first strength adjustment quantity.

[0115] Specifically, the number of communication time slices of the slave node may be adjusted to a first strength adjustment number.

[0116] Similarly, if the signal strength value is less than the preset second strength value, indicating that the communication quality of the slave node is poor, the second strength adjustment quantity can be calculated according to the preset second coefficient parameter and I, and the number of communication time slices of the slave node can be increased according to the second strength adjustment quantity. Specifically, the second strength adjustment number of communication time slices can be increased based on the existing number of communication time slices of the slave node.

[0117] In one embodiment, the preset first coefficient parameter includes: a first intensity coefficient and a second intensity coefficient.

[0118] Reference Figure 5 , the step of calculating the first intensity adjustment amount according to the preset first coefficient parameter and I may include the following sub-steps:

[0119] S211, calculating the ratio of I to the first intensity coefficient to obtain a first intensity ratio, if the first intensity ratio is not an integer, then extending the first intensity ratio to the next integer to obtain a first intensity adjustment amount, if the first intensity ratio is an integer, then taking the first intensity ratio as the first intensity adjustment amount;

[0120] or;

[0121] S212: Calculate the difference between I and the second intensity coefficient to obtain a first intensity adjustment amount.

[0122] Specifically, if the signal strength value is greater than a preset first strength value, the ratio of I to the preset first strength coefficient may be calculated to obtain a first strength ratio, and when the first strength ratio is not an integer, the first strength ratio is postponed to the next integer value, and the number of communication time slices of the slave node is adjusted according to the postponed first strength ratio. If the first strength ratio is an integer, the first strength ratio is used as the first strength adjustment amount.

[0123] For example, assuming I=3, the preset first strength coefficient is 2, and I / 2 can be calculated. It is calculated that I / 2=1.5, and 1.5 can be deferred to the next integer value to get 2, and then the number of communication time slices of the slave node is adjusted from 3 to 2. For another example, assuming I=6, the preset first strength coefficient is 2, and I / 2 can be calculated. It is calculated that 6 / 2=3, 3 is an integer value, and the number of communication time slices of the slave node can be adjusted from 6 to 3.

[0124] Or; calculate the difference between I and the second intensity coefficient to obtain the first intensity adjustment amount.

[0125] For example, assuming that I=3 and the preset second strength coefficient is 2, the first strength adjustment quantity can be calculated to be 3-2=1, and the number of communication time slices of the slave node can be adjusted from 3 to 1.

[0126] In one embodiment, the preset second coefficient parameters include: a third intensity coefficient and a fourth intensity coefficient.

[0127] As an example, the step of calculating the second intensity adjustment amount according to the preset second coefficient parameter and I may include the following sub-steps:

[0128] S221, calculating the ratio of I to the third intensity coefficient to obtain a second intensity ratio, if the second intensity ratio is not an integer, extending the second intensity ratio to the previous integer value to obtain a second intensity adjustment amount, if the second intensity ratio is an integer, taking the second intensity ratio as the second intensity adjustment amount;

[0129] or;

[0130] S222. Calculate the sum of I and the fourth intensity coefficient to obtain a second intensity adjustment amount.

[0131] If the signal strength value is less than the preset second strength value, it means that the communication quality of the slave node is poor. The ratio of I to the third strength coefficient can be calculated to obtain the second strength ratio. When the second strength ratio is not an integer, it is postponed to the previous integer value, and then the number of communication time slices of the slave node is adjusted according to the sum of the postponed second strength ratio and I.

[0132] For example, assuming I=3 and the third strength coefficient is 2, I / 2 can be calculated. It is calculated that I / 2=1.5, and 1.5 can be postponed to the previous integer value to obtain the second strength adjustment number of 1, and then the sum of the postponed second strength adjustment number and I is calculated, specifically 3+1=4, and the number of communication time slices from the node is adjusted from 3 to 4. For another example, assuming I=6 and the preset third strength coefficient is 2, I / 2 can be calculated. It is calculated that 6 / 2=3, the second strength adjustment number is 3, which is an integer value and does not need to be postponed. The sum of the second strength adjustment number and I can be calculated, specifically 6+3=9, and the number of communication time slices from the node can be adjusted from 6 to 9.

[0133] Alternatively, if the signal strength value is less than the preset second strength value, it indicates that the communication quality of the slave node is poor, and the sum of I and the fourth strength coefficient is calculated to obtain the second strength adjustment quantity, and then the number of communication time slices of the slave node is adjusted according to the second strength adjustment quantity.

[0134] For example, assuming I=3 and the preset fourth strength coefficient is 2, the sum of I and the preset fourth strength coefficient can be calculated, and the second strength adjustment quantity is calculated to obtain 3+2=5, and the number of communication time slices of the slave node can be adjusted from 3 to 5.

[0135] For the above example, if the signal strength value is greater than the preset second strength value and the signal strength value is less than the preset first strength value, the number of communication time slices of the slave node is not adjusted.

[0136] Reference Figure 6 , shows an operational flow chart of adjusting the communication time slice according to the signal loss rate provided by an embodiment of the present invention.

[0137] In an optional embodiment, the communication parameter value is a signal loss rate, and the parameter range value includes: a preset signal loss rate.

[0138] In order to dynamically average the signal loss rate, as an example, the step of adjusting the number of communication time slices of the slave node may include the following sub-steps:

[0139] S31. If the signal loss rate is less than the preset first loss rate, a first loss adjustment quantity is calculated according to the preset third coefficient parameter and I, and the number of communication time slices of the slave node is reduced according to the first loss adjustment quantity.

[0140] S32. If the signal loss rate is greater than the preset second loss rate, the second loss adjustment amount is calculated according to the preset fourth coefficient parameter and I, and the number of communication time slices of the slave node is increased according to the second loss adjustment amount.

[0141] Among them, the preset first loss rate is the minimum value of the loss range value, and the preset second loss rate is the maximum value of the loss range value.

[0142] The user can pre-set the first loss rate and the second loss rate, and the first loss rate and the second loss rate can be adjusted according to actual needs. Among them, the first loss rate is smaller than the second loss rate, and the loss range value can be obtained by setting the first loss rate and the second loss rate.

[0143] It can be determined whether the signal loss rate is within the loss range value. If the signal loss rate is less than the preset first loss rate, it means that the communication quality of the slave node is good. The first loss adjustment quantity is calculated according to the preset third coefficient parameter and I, and the number of communication time slices of the slave node is reduced according to the first loss adjustment quantity.

[0144] Specifically, the number of communication time slices of the slave node may be adjusted to a first loss adjustment number.

[0145] Similarly, if the signal strength value is greater than the preset second loss rate, indicating that the communication quality of the slave node is poor, the second loss adjustment amount can be calculated according to the preset fourth coefficient parameter and I, and the number of communication time slices of the slave node can be increased according to the second loss adjustment amount. Specifically, the second loss adjustment amount of communication time slices can be increased based on the existing number of communication time slices of the slave node.

[0146] In one embodiment, the preset third coefficient parameter includes: a first loss coefficient and a second loss coefficient.

[0147] Reference Figure 6 , the calculation of the first loss adjustment amount according to the preset third coefficient parameter and I may include the following sub-steps:

[0148] S311. Calculate the ratio of I to the first loss coefficient to obtain a first loss ratio. If the first loss ratio is not an integer, postpone the first loss ratio to the next integer to obtain a first loss adjustment amount. If the first loss ratio is an integer, take the first loss ratio as the first loss adjustment amount.

[0149] or;

[0150] S312. Calculate the difference between I and the second loss coefficient to obtain a first loss adjustment amount.

[0151] Specifically, the numerical range of the signal loss rate can be determined. If the signal loss rate is less than the preset first loss rate, it means that the communication quality of the slave node is good. The ratio of I to the preset first loss coefficient can be calculated to obtain the first loss ratio. When the first loss ratio is not an integer, the first loss adjustment amount is obtained by delaying to the next integer value, and the number of communication time slices of the slave node is adjusted according to the first loss adjustment amount. If the first loss ratio is an integer, the first loss ratio is used as the first loss adjustment amount.

[0152] For example, assuming I=3, and the preset first loss coefficient is 2, the ratio of I to the preset first loss coefficient can be calculated. The first loss ratio is calculated to be I / 2=1.5. The first loss ratio is not an integer value. 1.5 can be deferred to the next integer value to get 2, and then the number of communication time slices of the slave node is adjusted from 3 to 2. For another example, assuming I=6, and the preset first loss coefficient is 2, the first loss ratio can be calculated to be 6 / 2=3. 3 is an integer value, and the number of communication time slices of the slave node can be adjusted from 6 to 3.

[0153] In order to allocate a fixed value for the signal loss rate, if the signal loss rate is less than the preset first loss rate, the difference between I and the preset second loss coefficient can be calculated to obtain the first loss adjustment amount, and then the number of communication time slices of the slave node is adjusted according to the first loss adjustment amount.

[0154] For example, assuming that I=3 and the preset second loss coefficient is 2, the first loss adjustment quantity can be calculated to be 3-2=1, and the number of communication time slices of the slave node can be adjusted from 3 to 1.

[0155] In one embodiment, the preset fourth coefficient parameter includes: a third loss coefficient and a fourth loss coefficient;

[0156] Reference Figure 6 , the calculation of the second loss adjustment amount according to the preset fourth coefficient parameter and I may include the following sub-steps:

[0157] S321. Calculate the ratio of I to the third loss coefficient to obtain a second loss ratio. If the second loss ratio is not an integer, the second loss ratio is postponed to the previous integer value to obtain a second loss adjustment amount. If the second loss ratio is an integer, the second loss ratio is used as the second loss adjustment amount.

[0158] or;

[0159] S321. Calculate the sum of I and the fourth loss coefficient to obtain a second loss adjustment amount.

[0160] Similarly, if the signal loss rate is greater than the preset second strength value, it means that the communication quality of the slave node is poor, and the ratio of I to the third loss coefficient can be calculated to obtain the second loss ratio. If the second loss ratio is not an integer value, the second loss ratio can be extended to the previous integer value to obtain the second loss adjustment amount, and the number of communication time slices of the slave node is adjusted according to the sum of the second loss adjustment amount and I. If the second loss ratio is an integer, the second loss ratio is used as the second loss adjustment amount.

[0161] For example, assuming I=3, and the preset third loss coefficient is 2, the second loss ratio can be calculated. The second loss ratio is calculated to be I / 2=1.5. The second loss ratio is not an integer value. 1.5 can be deferred to the previous integer value to get 1, and then the sum of the deferred second strength ratio and I is calculated, specifically 3+1=4, and the number of communication time slices from the node is adjusted from 3 to 4. For another example, assuming I=6, and the preset first loss coefficient is 2, the second loss ratio can be calculated to be 6 / 2=3, 3 is an integer value, and then the sum of the second loss ratio and I is directly calculated, specifically 6+3=9, and the number of communication time slices from the node can be adjusted from 6 to 9.

[0162] Similarly, if the signal loss rate is greater than the preset second loss rate, it means that the communication quality of the slave node is poor. The sum of I and the preset fourth loss coefficient can be calculated to obtain the loss sum value, and then the number of communication time slices of the slave node can be adjusted according to the loss sum value.

[0163] For example, assuming I=3 and the preset fourth strength coefficient is 2, the sum of I and the preset fourth strength coefficient can be calculated, and the loss sum is 3+2=5, and the number of communication time slices of the slave node can be adjusted from 3 to 5.

[0164] For the above example, if the signal loss rate is greater than the preset first loss rate and the signal loss rate is less than the preset second loss rate, the number of communication time slices of the slave node may not be adjusted.

[0165] Reference Figure 7 , shows an operational flow chart of remaining time slice allocation provided by an embodiment of the present invention.

[0166] In one embodiment, after the number of communication time slices of the slave node is readjusted, the master node can communicate wirelessly with the slave node. During the communication process, the master node may successfully communicate with the slave node within one communication time slice; it may also fail to communicate with the slave node within multiple communication time slices and then succeed once; it may also fail to communicate with the slave node within multiple communication time slices.

[0167] During the wireless communication process between the master node and the slave node, if the communication is successful, the entire communication time slice may not be used, and there may be remaining communication time slices. In order to further reasonably utilize the remaining communication time slices for subsequent use by the slave nodes, the method may further include the following steps as an example:

[0168] S15. When it is determined that the communication between the master node and the current slave node fails and the number of communication failures is equal to the number of communication time slices of the current slave node, multiple remaining time slices are obtained. The multiple remaining time slices are obtained by accumulating the remaining communication time slices of each of the previous slave nodes that have not communicated after the master node has successfully communicated with the previous slave node.

[0169] S16. Allocate the multiple remaining time slices to the current slave node, so that the master node can use the multiple remaining time slices to perform wireless communication with the current slave node.

[0170] S17: When it is determined that the master node fails in wireless communication with the current slave node using the multiple remaining time slices, trigger the master node to perform wireless communication with the next slave node of the current slave node.

[0171] Specifically, after re-adjusting the number of communication time slices of the slave nodes, each master node can communicate with the slave node, and when it is determined that the master node successfully communicates with the current slave node, the number of communications between the master node and the current slave node can be counted. For example, if the master node fails to communicate with the slave node for the first time and succeeds for the second time, the number of communications is 2.

[0172] If the value of the communication times is less than the number of communication time slices of the slave node, it means that the communication quality between the master node and the slave node is high, the communication times are small during the wireless communication process, and the slave node has not used up all the communication time slices, and there are communication time slices remaining. In order to reasonably use the remaining communication time slices, the remaining communication time slices can be unified and accumulated to form a set of remaining time slices.

[0173] When it is determined that the communication between the master node and the current slave node fails, the number of communications between the master node and the current slave node may also be counted. For example, if the master node and the slave node fail to communicate for the first time and the second time, the number of communication failures is 2.

[0174] It can be determined whether the number of communication failures is equal to the number of communication time slices of the current slave node. If the number of communication failures is equal to the number of communication time slices of the slave node, it means that the master node fails to communicate with the current slave node during the time corresponding to the communication time slice of the slave node. In order to enable the master node to establish communication with the current slave node, multiple remaining time slices are obtained. The multiple remaining time slices can be a number of communication time slices extracted from the set of previously constructed remaining time slices.

[0175] Specifically, after the master node successfully communicates with several previous slave nodes before the current slave node, the communication time slices are accumulated for each of the previous slave nodes during which no communication is performed.

[0176] Assuming that 10 communication time slices have been accumulated before, 10 communication time slices can be allocated to the current slave node, so that the master node can continue to communicate wirelessly with the current slave node during the time corresponding to the multiple remaining time slices.

[0177] If it is determined that the master node has failed to establish wireless communication with the current slave node using multiple remaining time slices, it means that the master node and the current slave node cannot establish communication within the time corresponding to the multiple remaining time slices. In order to avoid repeated processing on a slave node, the master node can be triggered to establish wireless communication with the next slave node of the current slave node.

[0178] In yet another optional embodiment, the number of remaining time slices to be extracted may also be adjusted according to actual needs, for example, only two are extracted each time to prevent a slave node with poor quality from using up all remaining time slices.

[0179] Reference Figure 8 , shows an operation flow chart of a method for allocating communication time slices provided by an embodiment of the present invention.

[0180] Specifically, the operation of the communication time slice allocation method may include the following steps:.

[0181] In the first step, the master node communicates with the slave node. The wireless communication system includes a master node and n slave nodes (n≥2).

[0182] In the second step, within each cycle, each slave node is allocated i time slices by default (depending on the system time allocation resources, the number of time slices is at least 2). Within each time slice, the slave node communicates with the master node.

[0183] The third step is that in the wireless communication system, when the communication quality of a slave node is poor, the master node can complete the communication with the slave node with poor communication quality by scheduling the time slices of other slave nodes with better communication quality.

[0184] The fourth step is that there are n slave nodes in the wireless communication system, and each slave node is allocated i time slices to complete the current communication between the master and slave nodes; when the communication quality of some slave nodes in the entire wireless communication system is good, not all i time slices will be used to complete the current communication between the master and slave nodes, and im time slices or in time slices are sufficient to support the completion of the current communication between the master and slave nodes; when the communication quality of some slave nodes is poor, the time slice of a slave node with good communication quality can be dynamically allocated to the slave node with poor communication quality through the master node scheduling, that is, when the wireless communication quality is poor, the current slave node can have i+m time slices or i+n time slices to complete the current communication between the master and slave nodes; by dynamically adjusting the allocated communication time slice of each slave node, the reliability of the wireless communication of the entire system is guaranteed.

[0185] In this embodiment, the embodiment of the present invention provides a method for allocating communication time slices, and its beneficial effect is that: the present invention can calculate the communication parameter value of each slave node before the master node respectively communicates with N slave nodes wirelessly; and then adjust the number of communication time slices of each slave node according to the size of the communication parameter value, so that the master node can wirelessly communicate with each slave node according to the adjusted number of communication time slices. In this way, the communication time of the master and slave nodes can be reasonably allocated, avoiding the problem of long waiting time or insufficient communication time, improving the resource utilization rate of time and communication flexibility, shortening the communication time, and improving communication efficiency.
