In order to better understand the above technical solutions, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments. Before describing the embodiments of the present application in detail, for the sake of understanding, common technical terms are first introduced:
the boot program (Bootloader) is a program for booting the operating system, which runs before the operating system kernel runs, and can initialize hardware devices and establish a memory space mapping diagram, so that the software and hardware environment of the system reaches a proper state, and a correct environment is prepared for finally calling the operating system kernel.
Example one
Fig. 1 is a flowchart illustrating a dynamic configuration method of a communication protocol according to an embodiment of the present application.
The embodiment of the present application is exemplified by configuring the dynamic configuration method of the communication protocol in a wireless communication device, where the wireless communication device may be applied to a household appliance, and the household appliance may be, for example, a household air conditioner, a television, a refrigerator, and other intelligent household appliances.
The hardware of the household appliance mainly comprises an electric control module and a wireless communication device. The electric control module is used as the central nerve of the whole household appliance and has control and protection functions on the household appliance, for example, the electric control module of the variable frequency air conditioner has the functions of a frequency converter, a temperature controller, a timer, a protector and the like. A wireless communication device belongs to the transmission layer of the Internet of things, has the function of converting a serial port or TTL level into an embedded module which accords with the wireless network communication standard and is embedded into household appliances so as to realize networking, intellectualization and digitization of the household appliances.
In this embodiment, the wireless communication device may include a system on chip module and a flash memory module, where the flash memory module has an engineering mode partition and a plurality of protocol partitions, the engineering mode partition stores a logic application for detecting a wireless communication protocol type supported by the home appliance, and each protocol partition stores an independently operable wireless communication protocol.
For example, taking the WIreless communication device as a WIreless-Fidelity (WiFi) communication device (or referred to as a WiFi module), and the WIreless communication protocol as a WIreless WiFi communication protocol as an example, the main components of the WiFi module are: a WiFi SOC chip (i.e., a system on a chip) and a Flash memory module (Flash). The flash memory module may have an engineering mode partition for storing a logic application for detecting a type of a wireless communication protocol supported by the home appliance, and a plurality of protocol partitions, each of which may store an independently operable wireless communication protocol, that is, each of which is an application of an operating system + a protocol function. It is understood that each partition in the flash memory module corresponds to a partition address, and each partition has an independent corresponding space size.
As an example, the partition table of the flash memory module may be as shown in fig. 2, where fig. 2 is a schematic view of the partition table of the flash memory module in this embodiment. The partition table only lists partition schematic diagrams of multiple protocols, and each partition in the partition table sequentially stores corresponding protocols. For example, partition 1 may be an engineering mode partition, in which a logic application for detecting the type of wireless communication protocol supported by the household appliance is stored, and the corresponding partition Address is Address0, and the corresponding space size is size 0; the partitions 2, 3, 4 and … are protocol partitions, wherein the household appliance protocol is stored in the partition 2, the corresponding partition Address is Address1, and the corresponding space size is size 1; the protocol partition 3 stores a protocol of household appliance + e-commerce 1 (such as the kyoto), the corresponding partition Address is Address2, and the corresponding space size is size 2; the protocol partition 4 stores a household appliance + e-commerce 2 (such as ali) protocol, the corresponding partition Address is Address3, and the corresponding space size is size 3; in the protocol section 5, the household appliance + C protocol, etc. are stored, which are not listed here.
As shown in fig. 1, the method for dynamically configuring the communication protocol includes the following steps:
In practical applications, when the household appliance leaves a factory, the wireless communication device therein may be compatible with a plurality of protocols, so that after a user purchases the household appliance home, if the wireless communication protocol used by the internet of things at home is not consistent with the default communication protocol of the wireless communication device in the household appliance, at this time, the wireless communication protocol currently configured by the wireless communication device needs to be updated.
In the embodiment of the application, when the household appliance is powered on and started, the wireless communication protocol in the wireless communication device can be configured. Specifically, the user may control the household appliance to be powered on and started, for example, a terminal device of the user may be bound to the household appliance, and the user may control the household appliance to be powered on and started through the terminal device, or the user may directly control the household appliance to be powered on and started by touching a power key on the household appliance, or the user may control the household appliance to be powered on and started through a remote controller of the household appliance, or the user may set a fixed turn-on or turn-off time of the household appliance, which is not limited to this. The household appliance can be provided with a monitor to monitor the power-on starting operation triggered by the user, and when the power-on starting operation triggered by the user is monitored, the household appliance can be powered on and started.
The terminal device can be a hardware device with various operating systems, curved touch screens and/or display screens, such as a mobile phone, a tablet computer, a personal digital assistant and a wearable device.
In the embodiment of the application, when the household appliance is monitored to be powered on and started, the logic application in the engineering mode partition can be loaded through the bootstrap program in the system-on-chip module, wherein the logic application is used for detecting the wireless communication protocol supported by the household appliance.
Optionally, the default address in the loading address information may be read by the bootstrap program to load the logic application in the engineering mode partition, where the logic application is configured to read the model or protocol standard parameter, and detect the wireless communication protocol supported by the home appliance through the model or protocol standard parameter. The default Address is preset, for example, the default Address may be Address information corresponding to the first protocol partition, such as Address1 in fig. 2. For example, the wireless communication protocol supported by the household appliance may be determined from a pre-established comparison table according to model or protocol standard parameters of the household appliance. The pre-established comparison table may have a correspondence between a model and a wireless communication protocol type, or a correspondence between a protocol standard parameter and a wireless communication protocol type. For example, the protocol standard parameter is used to indicate an identifier of a type of wireless communication protocol supported by the household appliance, for example, the protocol standard parameter is 01, which may be denoted as a type a wireless communication protocol, the protocol standard parameter is 02, which may be denoted as a type B wireless communication protocol, and the like.
As an example, when it is monitored that the household appliance is powered on and started, a default address in the loading address information may be acquired, the loading address information of the bootstrap program is modified into the default address, then, the wireless communication device may be restarted, and the modified default address in the loading address information is loaded through the bootstrap program, so as to load a logic application in the engineering mode partition, where the logic application is configured to send an instruction for reading a model or protocol standard parameter to an electronic control module of the household appliance, and detect a wireless communication protocol supported by the household appliance through the model or protocol standard parameter.
For example, as shown in fig. 3, Address2 is an Address for the bootstrap program to read the loaded Address information, after the loaded Address is read, the Address2 Address value becomes 0x1234, and 0x1234 is the first Address corresponding to the logical application that needs to be actually run to detect the wireless communication protocol supported by the home appliance. That is, when the household appliance is monitored to be powered on and started, the loading address information of the bootstrap program can be modified to a default address (the first address is 0x1234), and then the wireless communication device is restarted. When the wireless communication device is restarted, in the boot program starting process, the first address 0x1234 in the loading address information is read, and the corresponding engineering mode partition is found through the first address, so that the loading of the logic application in the engineering mode partition is realized. When the logic application is in operation, the logic application can send an instruction for reading the model or protocol standard to the electric control module of the household appliance, and can detect which wireless communication protocol the household appliance supports according to the model or protocol standard when the model or protocol standard fed back by the electric control module is obtained.
And step 102, determining a target wireless communication protocol to be configured by the wireless communication device from a plurality of wireless communication protocols correspondingly stored in the plurality of protocol partitions according to the detection result of the logic application.
In the embodiment of the application, after the logic application detects the wireless communication protocols supported by the household appliance through model or protocol standard parameters, a target wireless communication protocol to be configured of the wireless communication device can be determined from a plurality of wireless communication protocols correspondingly stored in a plurality of protocol partitions according to a detection result of the logic application. That is, in the present application, it is possible to detect which wireless communication protocol is supported by the home appliance according to the model or the protocol standard parameter, and use the wireless communication protocol supported by the home appliance as the wireless communication protocol (i.e., the target wireless communication protocol) to which the wireless communication device is to be configured.
And 103, modifying the loading address information of the bootstrap program into the address information of the target protocol partition corresponding to the stored target wireless communication protocol, and restarting the wireless communication device.
In the embodiment of the application, each protocol partition in the flash memory module corresponds to one partition address, and each protocol partition has an independent corresponding space size. After the target wireless communication protocol to be configured by the wireless communication device is determined, the target protocol partition corresponding to the stored target wireless communication protocol can be determined, so that the address information of the target protocol partition can be determined.
Optionally, a corresponding relationship between each protocol partition, the wireless communication protocol stored in the protocol partition, and the address information of the protocol partition may be pre-established, and after a target wireless communication protocol to be configured by the wireless communication device is determined, the corresponding relationship may be queried to obtain the address information of the target protocol partition corresponding to the target wireless communication protocol.
It should be noted that the address information may be a first address of the target protocol partition, for example, referring to fig. 2 and fig. 3, assuming that the target wireless communication protocol is protocol 2, it may be determined that the address information of the target protocol partition corresponding to the storage protocol 2 is: address2, assuming that the first Address corresponding to the protocol partition storing protocol 2 is: 0x1234, it may be determined that the address information of the target partition is 0x 1234.
In the embodiment of the application, after the address information of the target protocol partition of the target wireless communication protocol is determined, the current loading address information of the boot program in the system-on-chip module may be modified to the address information of the target protocol partition of the corresponding storage target wireless communication protocol, so that the boot program loads the target wireless communication protocol stored in the target protocol partition according to the address information of the target protocol partition. Further, since the identification of the target protocol partition is performed in the boot program, the wireless communication apparatus needs to be restarted when the currently loaded address information of the boot program is modified.
And 104, loading the target wireless communication protocol stored in the target protocol partition by the bootstrap program in the process of restarting the wireless communication device.
In the embodiment of the application, in the process of restarting the wireless communication device, the target wireless communication protocol stored in the target protocol partition can be loaded to run through the bootstrap program according to the address information of the target protocol partition. Still taking the above example as an example, after determining that the head address of the target protocol partition is 0x1234, the bootstrap program may load the corresponding protocol 2 according to the head address to run.
In the embodiment of the application, wireless communication among multiple protocols is realized by adopting a partition loading mode, so that the condition that a bootstrap program only loads one target wireless communication protocol to operate at the same time can be ensured, the requirement on chip resources can be reduced, the production cost is reduced, and meanwhile, the condition that two mutually competing clients operate the protocols at the same time can be avoided. And the software coupling can be reduced, for example, when the function of the protocol 3 needs to be changed, only the code corresponding to the protocol 3 needs to be changed, and the codes corresponding to other protocols do not need to be changed, so that the complexity of the function change of the protocol can be reduced, and the change efficiency is improved. In addition, when the household appliance is produced, only the supported wireless communication protocol needs to be written, the firmware can be commonly used in a plurality of products, the applicability of the method can be improved, and the complexity in production can be reduced.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
on one hand, when the household appliance is monitored to be powered on and started, the logic application in the engineering mode partition is loaded through the bootstrap program in the system level chip module, the logic application is used for detecting the wireless communication protocol supported by the household appliance, then the target wireless communication protocol to be configured of the wireless communication device is determined from the plurality of wireless communication protocols correspondingly stored in the plurality of protocol partitions according to the detection result of the logic application, then the loading address information of the bootstrap program is modified into the address information of the target protocol partition correspondingly storing the target wireless communication protocol, the wireless communication device is restarted, and finally the target wireless communication protocol stored in the target protocol partition is loaded through the bootstrap program in the restarting process of the wireless communication device, so that the problem that the wireless communication among the plurality of protocols is realized through software compatibility with the plurality of protocols in the prior art can be effectively solved, the software coupling is high, the protocols of two mutually competing clients can be operated at the same time, and the technical problems of increasing chip resources and cost are caused, so that the dynamic configuration of the wireless communication protocol in the wireless communication device is realized, the wireless communication among various protocols is realized by adopting a partition loading mode, the condition that only one target wireless communication protocol is loaded by a bootstrap program to operate at the same time can be ensured, the requirement on the chip resources can be reduced, the production cost is reduced, and meanwhile, the condition that the protocols of the two mutually competing clients are operated at the same time can be avoided. In addition, the software coupling can be reduced, and the complexity of protocol function change is reduced, so that the change efficiency is improved.
On the other hand, the wireless WiFi communication device which is high in popularization rate and mature in technology is adopted as the wireless communication device, so that the applicability of the method can be improved.
For clarity of the above embodiment, another dynamic configuration method of a communication protocol is provided in the embodiments of the present application, see embodiment two.
Example two
Fig. 4 is a flowchart illustrating a dynamic configuration method of a communication protocol according to a second embodiment of the present application.
As shown in fig. 4, the method for dynamically configuring a communication protocol may include the following steps:
The execution process of step 201 may refer to the execution process of step 101 in the above embodiments, which is not described herein again.
In this embodiment of the application, after the logic application determines, according to the model or the protocol standard parameter, the wireless communication protocol corresponding to the model or the protocol standard parameter, it may be determined whether the wireless communication protocol determined by the logic application exists in a plurality of wireless communication protocols that should be stored in a plurality of protocol partitions, and specifically, it may be determined whether each protocol partition in the flash memory module is traversed to match the wireless communication protocol stored in each protocol partition with the wireless communication protocol determined by the logic application, and if the wireless communication protocol determined by the logic application exists in the plurality of wireless communication protocols, if the wireless communication protocol determined by the logic application is matched, step 203 may be executed, otherwise, step 204 is executed.
And step 203, taking the wireless communication protocol corresponding to the model or protocol standard parameter as a target wireless communication protocol.
In this embodiment of the application, when the logic application detects that the corresponding wireless communication protocol exists in the plurality of wireless communication protocols according to the model or protocol standard parameter, the wireless communication protocol corresponding to the model or protocol standard parameter may be used as the target wireless communication protocol. For example, when the logical application detects that the corresponding wireless communication protocol exists in the plurality of wireless communication protocols according to the model, the wireless communication protocol corresponding to the model may be taken as the target wireless communication protocol. Alternatively, when the logic application detects that the corresponding wireless communication protocol exists in the plurality of wireless communication protocols according to the protocol standard parameters, the wireless communication protocol corresponding to the protocol standard parameters may be taken as the target wireless communication protocol.
In this embodiment of the application, the default wireless communication protocol may be preset for a built-in program of the household appliance, or the default wireless communication protocol may be set by a user, which is not limited to this. For example, when the default wireless communication protocol is preset for a built-in program of the household appliance, the default wireless communication protocol may be specified as a wireless communication protocol stored corresponding to a protocol partition arranged at the first position in the plurality of protocol partitions, for example, the protocol 1 in fig. 2, or the default wireless communication protocol may be a wireless communication protocol stored corresponding to any one protocol partition in the plurality of protocol partitions, for example, a wireless communication protocol stored corresponding to a protocol partition arranged at the last position, or the default wireless communication protocol may also be a wireless communication protocol currently configured by the wireless communication device, which is not limited thereto.
In the embodiment of the application, when the logic application detects that the corresponding wireless communication protocol does not exist in the plurality of wireless communication protocols according to the model, or when the logic application detects that the corresponding wireless communication protocol does not exist in the plurality of wireless communication protocols according to the protocol standard parameters, a preset default wireless communication protocol can be found out from the plurality of wireless communication protocols, and the default wireless communication protocol is used as the target wireless communication protocol.
For example, when the default wireless communication protocol may be a wireless communication protocol stored in correspondence with a protocol partition arranged at the first bit in the plurality of protocol partitions, the protocol partition arranged at the first bit may be found from the plurality of protocol partitions, and then the wireless communication protocol stored in correspondence with the protocol partition arranged at the first bit is determined as the default wireless communication protocol, such as protocol 1 in fig. 2, and then the default wireless communication protocol is taken as the target wireless communication protocol.
The process of step 205-206 may refer to the process of step 103-104 in the above embodiments, which is not described herein again.
Compared with the previous embodiment, the technical solution in the embodiment of the present application at least has the following further technical effects or advantages:
when the logic application detects that the corresponding wireless communication protocol does not exist in the plurality of wireless communication protocols according to the model or protocol standard parameters, the preset default wireless communication protocol is found out from the plurality of wireless communication protocols, and the default wireless communication protocol is used as the target wireless communication protocol, so that the success rate of the bootstrap program for loading the target wireless communication protocol can be ensured, the condition that the bootstrap program cannot load the target wireless communication protocol is prevented, and the wireless communication device can normally communicate.
