Description

[0001] This application relates to the technical field of equipment upgrading, and particularly relates to an upgrading method, device, storage medium and master control end for equipment in a multi-connected unit system. Background Art

[0002] A multi-connected unit system is an on-line system composed of multiple devices. For example, an exemplary multi-connected unit system is an air-conditioning system. The multiple devices in the air-conditioning system include at least one outdoor air conditioner (such as a main outdoor unit and a slave outdoor unit, etc.) and at least one indoor air conditioner. Multiple devices in the multi-connected unit system usually communicate through a bus (such as a CAN bus).

[0003] Currently, in order to ensure the normal operation of the multi-connected unit system, related means usually adopt a non-stop upgrade strategy, that is, splitting the upgrade data packet into multiple upgrade data segments of a fixed length, and inserting each upgrade data segment into multiple rounds of communication in the bus to be transmitted to the target device, so as to achieve equipment upgrade.

[0004] However, in the current non-stop upgrade method, when the segmented upgrade data inserted in each round of communication in the bus is superimposed on the device service data, it is easy to cause the load in the bus to be too high, affecting the normal operation of the multi-connected unit system, or the load in the bus to be too low, resulting in a low upgrade efficiency.

[0027] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments provided herein are only used to explain the present disclosure and are not used to limit the present disclosure. In addition, the embodiments provided below are partial embodiments for implementing the present disclosure, rather than all embodiments for implementing the present disclosure. Without conflict, the technical solutions described in the embodiments of the present disclosure can be implemented in any combined manner.

[0028] It should be noted that in the embodiments of the present disclosure, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, so that a method or device including a series of elements not only includes the clearly recited elements, but also includes other elements not explicitly listed, or further includes elements inherent to the implementation of the method or device.

[0029] For example, the method for upgrading devices in the multi-connected air-conditioning system provided by the embodiments of the present disclosure includes a series of steps, but the method for upgrading devices in the multi-connected air-conditioning system provided by the embodiments of the present disclosure is not limited to the recited steps.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this disclosure.

[0031] It can be understood that in the specific implementation manners of the present application, when related data is involved and the embodiments of the present application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of the related data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0032] Figure 1A flowchart of a method for upgrading devices in a multi-connected unit system according to an embodiment of the present application is schematically shown. Multiple devices included in the multi-connected unit system perform polling communication through a bus (such as a CAN bus) (polling communication means communicating in rounds, and each round of communication starts from a polling command initiated by one device and ends when the remaining other devices have reported their respective device information). The bus is connected to a master control end. The execution subject of the method for upgrading devices in this multi-connected unit system can be any master control end with processing capabilities and connected to the bus. The master control end can be a preset networked device or any device with processing capabilities in the multi-connected unit system, etc. The multi-connected unit system can be an air-conditioning system or other on-line systems that communicate through a bus.

[0033] In a scenario of the present application, the multi-connected unit system is specifically an air-conditioning system. Multiple devices in the air-conditioning system include at least one outdoor air conditioner (specifically including a main outdoor unit and a slave outdoor unit) and at least one indoor air conditioner. A preset networked device is connected to the bus as the master control end, or the main outdoor unit can be used as the master control end. In this air-conditioning system, the "main outdoor unit" and the "slave outdoor unit and the at least one indoor air conditioner" perform polling communication through the bus. Specifically, the specific process of each round of communication in the polling communication is as follows: (1) The main outdoor unit initiates a polling command (such as a start command) through the bus; (2) After the "slave outdoor unit and the at least one indoor air conditioner" receive this polling command, the "slave outdoor unit and the at least one indoor air conditioner" will report their respective status information, control information, and other device information according to the IP address competition. After the "slave outdoor unit and the at least one indoor air conditioner" have all reported, they will not report actively again; (3) The main outdoor unit determines that the bus is idle for a predetermined idle duration (such as 100 ms) and initiates a newly initiated polling command in the bus to trigger a new round of communication.

[0034] The master control end can execute the steps of the method for upgrading devices in the multi-connected unit system as Figure 1 shown. The method for upgrading devices in this multi-connected unit system can specifically include step S110 to step S140.

[0035] Step S110, after initiating device upgrade, detect the real-time bus load rate during each round of communication in the bus;

[0036] Step S120, perform an equalization calculation based on the real-time bus load rate of each round and the target bus load rate to obtain the adapted bus load rate of each round;

[0037] Step S130, according to the adapted bus load rate of each round, intercept the upgrade data segment of each round from the upgrade data packet;

[0038] Step S140, insert the upgrade data segments of each round into the communication of the corresponding round, so as to transmit the upgrade data packet to the target device among the multiple devices through the bus for device upgrade.

[0039] In response to the upgrade instruction, the master control end initiates device upgrade. After initiating the device upgrade, it detects the real-time bus load rate (load_current) during each round of communication in the bus. For example, after initiating the device upgrade at time A, it can detect the real-time bus load rate (load_current1) during the first round of communication in the bus after time A, and can further detect the real-time bus load rate (load_current2) during the second round of communication after time A.

[0040] In an embodiment of the present application, a target bus load rate (Load_Target) is predetermined, and an equilibrium calculation is performed based on the real-time bus load rate of each round and the target bus load rate to obtain the adapted bus load rate (Adjust_load) of each round. For example, an equilibrium calculation is performed based on load_current1 and Load_Target to obtain the adapted bus load rate (Adjust_load1) of the first round, and an equilibrium calculation is performed based on load_current2 and Load_Target to obtain the adapted bus load rate (Adjust_load2) of the second round.

[0041] Furthermore, according to the adapted bus load rate of each round, the upgrade data segments of each round are intercepted from the upgrade data packet. For example, refer to Figure 2 , intercept the data segment 201 from S1 to S2 from the upgrade data packet (S) according to Adjust_load1 to obtain the upgrade data segment 1 of the first round, and intercept the data segment 202 from S2 to S3 from the upgrade data packet (S) according to Adjust_load2 to obtain the upgrade data segment 2 of the second round. Among them, the lengths of the segments from S1 to S2 and from S2 to S3 may be the same or different.

[0042] Furthermore, insert the upgrade data segments of each round into the communication of the corresponding round. For example, insert the upgrade data segment 1 into the first round of communication in the bus, and transmit the upgrade data segment 1 to the target device among the multiple devices through the bus; insert the upgrade data segment 2 into the second round of communication in the bus, and transmit the upgrade data segment 2 to the target device among the multiple devices through the bus. When the upgrade data packet is completely transmitted to the target device, the target device can combine all the upgrade data segments into the upgrade data packet to perform device upgrade. Among them, the target device is one or several devices among the multiple devices in the multi-connected system.

[0043] In this way of the embodiment of the present application, when performing communication in each round according to the bus, an adaptive bus load rate for each round is calculated by balancing the real-time bus load rate during each round of communication with the target bus load rate. Then, according to the adaptive bus load rate for each round, the upgrade data segment for each round is intercepted from the upgrade data packet. Subsequently, the upgrade data segment for each round is inserted into the communication of the corresponding round and transmitted to the target device. In this way, the upgrade data packet can be reliably segmented and transmitted according to the bus load, and it can reliably avoid the situation that the excessive load in the bus affects the normal operation of the multi-connected system or the low load in the bus leads to low upgrade efficiency. Thus, on the basis of ensuring the working performance of the multi-connected system, the non-stop upgrade efficiency of the devices in the multi-connected system is effectively improved.

[0044] The following describes Figure 1 When upgrading the devices in the multi-connected system in the embodiment, specific embodiments that are further optional under each step.

[0045] In one embodiment, referring to Figure 3 , detecting the real-time bus load rate during each round of communication in the bus includes: step S310, determining the communication limit duration during each round of communication in the bus; step S320, determining the communication interval time between each round of communication in the bus and the previous round of communication; step S330, calculating according to the communication limit duration and the communication interval time during each round of communication to obtain the real-time bus load rate during each round of communication.

[0046] The communication limit duration (Time_max) during each round of communication is the maximum duration for completing communication in each round, that is, the maximum polling time that does not affect the normal operation of the multi-connected system, which means that all devices in the bus can send and complete their respective device information within the communication limit duration of one round. For example, within the communication limit duration of one round, it is required that both the outdoor unit and the at least one air-conditioning indoor unit can complete reporting their respective status information and control information and other device information to the main outdoor unit. The communication limit duration during each round of communication can be preset according to the actual situation, and the present application does not make special limitations on this.

[0047] The communication interval time between each round of communication and the previous round of communication. For example, after the main outdoor unit initiates a polling command 1 for one round through the bus, the main outdoor unit determines that the bus is idle for a predetermined idle duration (such as 100 ms) and then initiates a new round of polling command 2 in the bus. The communication interval time between the new round of communication and the previous round of communication is the "interval time between the moment of initiating polling command 1 and the moment of initiating polling command 2".

[0048] In this way of calculating the real-time bus load rate during each round of communication based on the communication limit duration and communication interval time during each round of communication, by considering the communication limit duration and communication interval time during each round of communication to calculate the real-time bus load rate, the accuracy of the real-time bus load rate can be effectively guaranteed.

[0049] Specifically, in one implementation manner, the calculation of the real-time bus load rate during each round of communication according to the communication limit duration and the communication interval time during each round of communication may include: calculating according to the formula Load_current = Time_current / Time_max × 100%, where Load_current refers to the real-time bus load rate during each round of communication, Time_current refers to the communication interval time during each round of communication, and Time_max refers to the communication limit duration during each round of communication.

[0050] Calculating the real-time bus load rate during each round of communication according to the formula Load_current = Time_current / Time_max × 100%, and the real-time bus load rate calculated in this way is used in the solution of this application. The applicant finds that the reliability of inserting data during each round of communication can be reliably improved.

[0051] In one embodiment, the balanced calculation of the real-time bus load rate and the target bus load rate for each round to obtain the adapted bus load rate for each round may include: performing a balanced calculation of the real-time bus load rate and the target bus load rate for each round through a proportional-integral-derivative control algorithm to obtain the adapted bus load rate for each round.

[0052] The proportional-integral-derivative control algorithm is the PID algorithm. By performing a balanced calculation of the real-time bus load rate and the target bus load rate for each round through the PID algorithm, the real-time bus load rate approaches the target bus load rate, and the adapted bus load rate for each round is obtained (i.e., Adjust_load = PID(Load_Target, Load_current)). Among them, the control effect can be optimized by adjusting the PID parameters (proportional, integral, derivative) in the PID algorithm, and the PID parameters (proportional, integral, derivative) in the PID algorithm can be pre-adjusted. The adapted bus load rate for each round is obtained through a balanced calculation by the PID algorithm. Based on the adapted bus load rate calculated in this way, the amount of data in the reasonable upgrade data segment for each round can be reliably determined.

[0053] Optionally, in other embodiments, the step of performing an equalization calculation based on the real-time bus load rate and the target bus load rate for each round to obtain the adapted bus load rate for each round may be: performing an average calculation or other calculations on the real-time bus load rate and the target bus load rate. Optionally, in other embodiments, the step of performing an equalization calculation based on the real-time bus load rate and the target bus load rate for each round to obtain the adapted bus load rate for each round may be: performing an equalization calculation based on the real-time bus load rate and the target bus load rate for each round through a proportional-integral control algorithm (i.e., PI algorithm) or a proportional-derivative control algorithm (i.e., PD algorithm) to obtain the adapted bus load rate for each round.

[0054] In one embodiment, referring to Figure 4 , the step of intercepting the upgrade data segment for each round from the upgrade data packet according to the adapted bus load rate for each round may include: Step S410, calculating according to the adapted bus load rate, the communication limit duration, and the communication baud rate of the bus for each round to obtain the adapted data volume for each round; Step S420, obtaining the inserted data volume for each round according to the adapted data volume for each round; Step S430, intercepting the upgrade data segment of the inserted data volume for each round from the upgrade data packet.

[0055] The communication baud rate (Baud) of the bus is the data transmission rate on the bus. For example, 125 kbps, 250 kbps, 500 kbps, or 1 Mbps, etc. By calculating according to the adapted bus load rate, the communication limit duration, and the communication baud rate of the bus for each round, the reasonably adapted data volume (Adjust_size) for each round can be obtained. For example, the adapted data volume Adjust_size1 for the first round is calculated according to the adapted bus load rate Adjust_load1, the communication limit duration Time_max, and the communication baud rate Baud of the bus for the first round; the adapted data volume Adjust_size2 for the first round is calculated according to the adapted bus load rate Adjust_load2, the communication limit duration Time_max, and the communication baud rate Baud of the bus for the second round.

[0056] Then, based on the adaptation data volume of each round, the inserted data volume of each round is obtained, and the upgrade data segment of the inserted data volume of each round is intercepted from the upgrade data packet. For example, based on the adaptation data volume Adjust_size1 of the first round, the inserted data volume Ota_size1-1 of the first round (i.e., the length of the segment from S1 to S2) is obtained. Based on the adaptation data volume Adjust_size2 of the second round, the inserted data volume Ota_size1-2 of the second round (i.e., the length of the segment from S2 to S3) is obtained. Further, the upgrade data segment 1 of the first round can be intercepted from the upgrade data packet (S) for the data from S1 to S2, and the upgrade data segment 2 of the second round can be intercepted from the upgrade data packet (S) for the data from S2 to S3. Calculating and determining the inserted data volume of each round in the manner of this embodiment can further reasonably intercept the upgrade data segment of each round.

[0057] Further, in an embodiment, the calculation based on the adaptation bus load rate, communication limit duration, and communication baud rate of the bus for each round to obtain the adaptation data volume of each round may specifically include: calculating according to the formulas Adjust_time = Time_max × Adjust_load and Adjust_size = Adjust_time × CAN_baud / 8. Here, Adjust_size refers to the adaptation data volume of each round, Adjust_time refers to the adaptation duration of each round, CAN_baud refers to the communication baud rate of the bus, Time_max refers to the communication limit duration of each round, and Adjust_load refers to the adaptation bus load rate of each round.

[0058] The applicant found that calculating according to the formulas Adjust_time = Time_max × Adjust_load and Adjust_size = Adjust_time × CAN_baud / 8 can extremely reasonably obtain the adaptation data volume of each round.

[0059] Further, in an embodiment, the obtaining of the inserted data volume of each round based on the adaptation data volume of each round may include: calculating according to the formulas Ota_size1 = Ota_size2 + Adjust_size and Ota_size1 = Limit(Ota_size_min, Ota_size_max), where Ota_size1 refers to the inserted data volume of each round, Ota_size2 refers to the predetermined standard data volume, Adjust_size refers to the adaptation data volume of each round, Ota_size_min is the predetermined data volume lower limit, and Ota_size_max is the predetermined data volume upper limit.

[0060] The specific meaning of this formula is as follows: After calculating the initial Ota_size1 according to the formula Ota_size1 = Ota_size2 + Adjust_size, if the initial Ota_size1 is between Ota_size_min and Ota_size_max, then this initial Ota_size1 is the final inserted data volume; if the initial Ota_size1 is less than Ota_size_min, then the final inserted data volume is equal to Ota_size_min; if the initial Ota_size1 is greater than Ota_size_max, then the final inserted data volume is equal to Ota_size_max.

[0061] After calculating the adaptation data volume Adjust_size for each round, calculate according to the formula Ota_size1 = Ota_size2 + Adjust_size and Ota_size1 = Limit(Ota_size_min, Ota_size_max) to determine the final inserted data volume. The applicant finds that using the inserted data volume calculated in this way to intercept the upgrade data segment can effectively ensure the rationality of the load in the bus.
