Referring to fig. 1 and fig. 2, a firmware upgrade method according to an embodiment of the present invention is applied to a distributed multi-tier system 100. The distributed multi-tier system 100 includes a plurality of components 10, the plurality of components 10 including a current-level component 12 and a lower-level component 14 in communication with the current-level component. The firmware upgrading method comprises the following steps:
s12, the current-stage component 12 acquires the firmware upgrade program;
s14, the current stage part 12 judges whether or not there are a plurality of lower stage parts 14;
s16, the current-stage component 12 broadcasts the firmware upgrade program to the plurality of lower-stage components 14 when the plurality of lower-stage components 14 exist.
The firmware upgrading method of the present embodiment can be implemented by the distributed multi-tier system 100 of the present embodiment. Step S12, step 14, step 16 may be implemented by the current stage component 12. The distributed multi-tier system 100 includes a plurality of components 10. The plurality of components 10 includes a current level component 12 and a lower level component 14 in communication with the current level component. The current stage component 12 is used to obtain a firmware upgrade program. The current level component 12 is used to determine whether a plurality of lower level components 14 exist and broadcast a firmware upgrade program to the plurality of lower level components 14 when the plurality of lower level components 14 exist.
In the firmware upgrading method and the distributed multi-layer system 100 according to the embodiment of the present invention, the front-stage component 12 acquires the firmware upgrading program and transmits the firmware upgrading program to the plurality of lower-stage components 14 in a broadcast manner, and the plurality of lower-stage components 14 receive and upgrade the firmware upgrading program at the same time. In this way, each of the current-stage component 12 and the lower-stage component 14 of the distributed multi-layer system 100 can be upgraded simultaneously, so that the time required for upgrading the distributed multi-layer system 100 is short, the efficiency is high, and the user experience is good.
Specifically, the distributed multi-tier system 100 is composed of a client application, an application server tier, and a database service tier. The distributed multi-tier system 100 includes a plurality of components 10, with coupling connections between the components 10. Each component 10 of the distributed multi-tier system employs a master-slave data transfer and storage approach. The components 10 are connected and communicated with each other through an RS485 communication bus.
It will be appreciated that the current stage component 12 may obtain the firmware upgrade program through an external port. For example, the external port of the front-stage component 12 may obtain the firmware upgrade program from the outside in a USB, SD card, WIFI, or other manners.
It will be appreciated that the front level component 12 may send the firmware upgrade program to the RS485 communication bus and inform the plurality of lower level components 14 of the firmware upgrade program in a broadcast fashion at the same time, and the lower level components 14 may directly obtain the firmware upgrade program from the RS485 communication bus.
It is understood that the distributed multi-tier system 100 may be applied to an air conditioner. For example, the components 10 may include a cluster controller, an outdoor unit, an MS, an indoor unit, and a line controller. The centralized controller, the outdoor unit, the MS, the indoor unit and the line controller are all connected and communicated with each other through an RS485 communication bus. In one embodiment, the centralized controller may be considered as the current stage part 12, and the outdoor unit may be considered as the lower stage part 14. When the centralized controller learns that the centralized controller is connected with a plurality of outdoor units through the RS485 communication bus. At this time, the centralized controller may simultaneously send the firmware upgrade program to the plurality of outdoor units in a broadcast manner.
In some embodiments, referring to fig. 3 and 4, the firmware upgrading method includes the following steps:
s11, initializing the distributed multi-layer system 100;
s13, each component 10 obtaining current firmware information of a plurality of components 10; and
s15, judging whether any part 10 is triggered to be upgraded, if yes, entering step S12; if not, the step S15 is returned to.
In some embodiments, the firmware upgrade method may be performed by the distributed multi-tier system 100. Distributed multi-tier system 100 includes components 10 and processors 20. Steps S11 and S15 may be implemented by the processor 20. Step S13 may be implemented by component 10. The processor 20 is used to initialize the distributed multi-tier system 100. Each component 10 is used to obtain current firmware information for the plurality of components 10. And the processor 20 is used for judging whether any part 10 is triggered to upgrade the firmware, if yes, the current-stage part 12 obtains a firmware upgrading program; if not, the processor 20 continues to determine whether any of the components 10 has triggered a firmware upgrade.
Therefore, the firmware upgrading can be checked one by one for any component 10, and the condition that the distributed multilayer system 100 does not start an upgrading step when the component 10 triggers upgrading through an external interface is avoided.
It is understood that initialization refers to the initialization of data objects or variables in the field of computer programming, and how initialization depends on the program language used and the properties of the object to be initialized, such as the storage type. The program structure for initialization is called an initializer or initialization list. The distributed multi-tier system 100 may be initialized by encoding an address.
It is understood that the distributed multi-tier system 100 may include centralized controllers, line controllers, outdoor units, indoor units, etc. The centralized controller, the line controller, the outdoor unit, and the indoor unit communicate with each other via the RS485 communication bus, and each component 10 notifies its own firmware information to any other component 10. In this manner, each component may be aware of firmware information for any component 10 in the distributed multi-tier system 100.
It will be appreciated that the hub or cable will typically be located in a location that is relatively accessible indoors. Thus, a firmware upgrade typically selects either a hub or a line director as the entry point for the triggering of the firmware upgrade. And an external interface of the centralized controller or the line controller acquires a firmware upgrading program from the outside in a USB (universal serial bus), SD (secure digital) card, wireless WIFI (wireless fidelity) and other modes, and then triggers upgrading. On the contrary, the outdoor unit is generally installed outdoors, and the indoor unit is generally installed in a ceiling or the like, and is not generally selected as an entry point for triggering upgrade.
In some embodiments, referring to fig. 5, step S13 further includes the following sub-steps:
s132, the distributed multi-layer system 100 allocates addresses to the indoor units; and
and S134, the distributed multilayer system 100 operates normally.
In some embodiments, steps S132 and S134 may be implemented by the distributed multi-tier system 100. The distributed multi-tier system 100 is used to assign addresses to the indoor units. The distributed multi-tier system 100 operates normally.
Thus, addresses are allocated to the indoor units, so that the distributed multi-layer system 100 can transmit and receive data according to the corresponding addresses, and the distributed multi-layer system 100 can normally operate.
Specifically, address coding may be performed on the indoor units in sequence. The distributed multi-layer system 100 transmits data to corresponding target addresses according to address matching in the process of transmitting the data, so that the error rate can be reduced.
In some embodiments, the firmware information includes model information, software version information, chip information, supported function information, and firmware size.
Therefore, the firmware upgrading information of the component can be quickly acquired through the model information, the software version information, the chip information and the supported function information of the component.
In some embodiments, referring to fig. 6, when the front-level component 12 has transparent transmission capability, the firmware upgrade method further includes the following steps:
s17, the current-stage component 12 obtains the software information of the firmware upgrade program;
s18, the current stage component 12 determines whether it is suitable for upgrading according to the software information and the current firmware information, if not, it goes to step S14 and broadcasts the firmware upgrading program to the plurality of lower stages 14 by the current stage component 12 using the transparent transmission capability when there are a plurality of lower stages 14. And firmware upgrade with a firmware upgrade program for the front-stage component 12 when appropriate for the upgrade.
In some embodiments, the firmware upgrade method may be implemented by the distributed multi-tier system 100. The front stage component 12 has transparent transmission capability. The current level component 12 is used to obtain software information of the firmware upgrade program. The current-stage component 12 is configured to determine whether the upgrade is appropriate according to the software information and the current firmware information, and if not, the current-stage component 12 is configured to determine whether a plurality of lower-stage components 14 exist and broadcast a firmware upgrade program to the plurality of lower-stage components 14 by using the transparent transmission capability when the plurality of lower-stage components 14 exist; and performing firmware upgrade using a firmware upgrade program when upgrade is appropriate.
In this manner, the front level component 12 can be upgraded when appropriate and pass data directly to the lower level component 14 when not appropriate, in a manner that increases the rate of data transfer and reduces the time required for upgrade.
It can be understood that transparent transmission refers to that in the process of transmitting a service, a transmission system only needs to transmit data to be transmitted to a destination node without processing the transmitted data on the premise of ensuring the transmission quality. The current stage component 12 may pass the transmitted data directly to the lower stage component 14 in a pass-through manner.
It is understood that the chip having the storage capability of the current-stage component 12 includes a Bootloader area, an application program area, a backup program area, and a program information area. The Bootloader area is entered immediately after the power on of the front-stage component 12. The Bootloader area is responsible for managing the application program area and the backup program area. The application area includes programs having specific functions. The backup program area may backup the upgraded firmware program. When the current-stage component receives the program of the upgraded firmware, the current-stage component compares the program of the upgraded firmware with the program memory of the backup program area. If the backup program area can accommodate the program of the upgraded firmware, the backup program area saves the program of the upgraded firmware. The program information area is arranged at the end of the application program area and the backup program area. The program information area includes information such as model information, version, program size, and verification of the current-level component.
It is understood that the current stage component 12 reads the software information of the firmware upgrade program, and the software information includes model information, version, program size, verification, and the like. The current stage component 12 compares the read information with current firmware information of the current stage component 12 to determine whether an upgrade is appropriate. For example, when the model information of the firmware upgrade program does not coincide with the model information of the current-stage component 12, the current-stage component 12 is not suitable for upgrade. Or the model information of the firmware upgrade program coincides with the model information of the current-stage component 12, although the version information of the firmware upgrade program does not coincide with the version information of the current-stage component 12, the current-stage component 12 is still suitable for upgrade.
In certain embodiments, step S16 includes the following sub-steps
And S162, when the firmware upgrading program is suitable for upgrading, the current-stage component 12 is used for storing the firmware upgrading program firstly and then broadcasting the firmware upgrading program.
In some embodiments, the firmware upgrade method may be implemented by the distributed multi-tier system 100. Step S162 may be implemented by the current stage component 12. The current stage component 12 is used to store the firmware upgrade program before broadcasting the firmware upgrade program when appropriate for upgrading.
The current stage component 12 stores the firmware upgrade program and broadcasts the firmware upgrade program, so that the current stage component 12 can determine when to upgrade according to the requirement, and the stored firmware upgrade program can be directly forwarded to other components 10 needing to be upgraded.
Specifically, the current-stage component 12 stores the firmware upgrade program in the backup program area of the current-stage component 12 when the upgrade is appropriate. When the upgrade of the current-stage component 12 fails, the current-stage component 12 may be upgraded again using the saved firmware upgrade program. In addition, when the other components 10 fail to be upgraded by broadcasting, the current-stage component 12 may directly acquire the firmware upgrade program from the backup program area and directly forward to the failed component 10 in a one-to-one manner.
In some embodiments, referring to fig. 7, the firmware upgrading method further includes the following steps:
s19, the current-stage component 12 determines whether it is a bottom-stage component; if yes, go to step S16; and
when the current-stage component 12 determines that the lower-stage component 14 does not exist, it is a bottom-stage component.
In some embodiments, the firmware upgrade method may be implemented by the distributed multi-tier system 100. Step S19 may be implemented by the current stage component 12. The current-stage component 12 is used for judging whether the current-stage component is a bottom-stage component; if yes, the current-stage component 12 acquires software information of the firmware upgrade program; and the current stage part 12 is used to judge that the lower stage part 14 does not exist when it is the bottom stage part itself.
In this manner, by determining whether the component is a bottom-level component stage by stage, each stage of the distributed multi-layer system 100 can be checked and each component can obtain a firmware upgrade program, so that all components of the distributed multi-layer system 100 can be covered.
In some embodiments, referring to fig. 8, the firmware upgrading method further includes the following steps:
s21, the current stage part 12 inquiring the firmware upgrade status of the plurality of lower stage parts 14 when the plurality of lower stage parts 14 exist; and each lower level component 14 feeds back the firmware upgrade status to the current level component 12.
In some embodiments, the firmware upgrade method may be implemented by the distributed multi-tier system 100. Step S21 may be implemented by the current level component 12 and the lower level component 14. The current-stage component 12 is used to query the firmware upgrade status of the plurality of lower-stage components 14 when the plurality of lower-stage components 14 exist. Each lower level component 14 is used to feed back the firmware upgrade status to the current level component 12.
In this manner, the front level element 12 and the lower level element 14 communicate with each other, thereby increasing the rate of information exchange.
In some embodiments, referring to fig. 9, the plurality of components 10 includes a lower component 16 in communication with a lower component 14; the lower level component 14 forwards the firmware upgrade program to the lower level component 18 while feeding back the firmware upgrade status to the current level component 12.
In some embodiments, the firmware upgrade method may be implemented by the distributed multi-tier system 100. The plurality of components 10 includes a lower level component 16 in communication with a lower level component 14. The lower level component 14 is used to forward the firmware upgrade program to the lower level component 18 while feeding back the firmware upgrade status to the current level component 12.
The lower level component 14 forwards the firmware upgrade program to the lower level component 18 while feeding back the firmware upgrade status to the current level component 12. Thus, the efficiency of communication can be improved, and the time for upgrading can be reduced.
Specifically, referring to fig. 10, in an embodiment, the external interface of the centralized controller 12 obtains the firmware upgrade program through USB or the like. The outdoor unit 14(14a), the outdoor unit 14(14b), and the outdoor unit 14(14c) communicate with each other via an RS485 communication a bus. The outdoor unit 14(14a) serves as an outdoor master of the RS485 communication bus. The outdoor unit 14(14a), the indoor unit 16(16B), and the indoor unit 16(16c) communicate with each other via another RS485 communication B bus. The centralized controller 12 issues the firmware upgrade program to the outdoor unit 14(14 a). The outdoor unit 14(14a) determines whether the model information of the firmware upgrade program matches the model information of the outdoor unit 14, and if so, the outdoor unit 14(14a) performs broadcast upgrade on the outdoor unit 14(14b) and the outdoor unit 14(14c) through an RS485 communication a bus. Meanwhile, the outdoor unit 14(14a) determines whether the model information of the firmware upgrade program matches the model information of the indoor unit 16, and if so, the outdoor unit 14(14a) performs broadcast upgrade on the indoor unit 16(16a), the indoor unit 16(16B), and the indoor unit 16(16c) through an RS485 communication B bus.
Of course, the connection method of the central controller 12, the outdoor unit 14, and the indoor units 16 is not limited to the above embodiment, and in one embodiment, the central controller 12 may be connected to the indoor units 16 by wires. In still other embodiments, other implementations are used depending on actual installation requirements.
