Detailed Description

The method for dynamically configuring the communication protocol mainly aims at the technical problems that in the prior art, wireless communication among multiple protocols is realized through software compatibility with multiple protocols, software coupling is high, two mutually competing clients can run at the same time, and chip resources and cost are increased.

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:

step 101, when it is determined that the wireless communication protocol currently configured for the wireless communication device is to be updated, loading a logic application in the engineering mode partition through a bootstrap program in the system-on-chip module, wherein the logic application is used for reading model or protocol standard parameters of the household appliance and detecting the wireless communication protocol supported by the household appliance through the model or protocol standard parameters.

In practical application, when the household appliance leaves a factory, the wireless communication device in the household appliance can 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 in the home is not consistent with the default communication protocol of the wireless communication device in the household appliance, the user can dynamically configure the wireless communication protocol in the wireless communication device by triggering the household appliance, namely, the wireless communication protocol currently configured by the wireless communication device is updated.

For example, the embodiment of the application can set a trigger button on the household appliance or on a remote controller corresponding to the household appliance, and a user can trigger the household appliance through the trigger button to dynamically configure the wireless communication protocol in the wireless communication device. When the household appliance detects that a user triggers the button, the wireless communication device can determine that the wireless communication protocol currently configured by the wireless communication device is to be updated when receiving a detection instruction which is sent by the household appliance and aims at the wireless communication protocol supported by the household appliance, and at the moment, the logic application in the engineering mode partition can be loaded through a bootstrap program (Bootloader) in the system level chip module, wherein the logic application is used for reading the model or protocol standard parameter of the household appliance and detecting the wireless communication protocol supported by the household appliance through the model or protocol standard parameter.

Alternatively, 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 determined that a wireless communication protocol currently configured for a wireless communication device is to be updated, address information of an engineering mode partition may be acquired, and loading address information of a bootstrap program is modified into address information of the engineering mode partition, and then, the wireless communication device may be restarted, and a logic application in the engineering mode partition corresponding to the modified loading address information is loaded through the bootstrap program, where the logic application is configured to send an instruction for reading a model or protocol standard to an electronic control module of a home appliance, and detect the wireless communication protocol supported by the home appliance through the model or protocol standard. It should be noted that the address information may be a first address of the engineering mode partition.

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 it is determined that the wireless communication protocol currently configured by the wireless communication apparatus is to be updated, the loading address information of the boot program may be modified to the first address 0x1234 of the engineering mode partition, and then the wireless communication apparatus 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 communication protocol corresponding to the backup protocol partition address information stored in the electric control module of the household appliance and a plurality of wireless communication protocols corresponding to the protocol partitions according to the detection result of the logic application.

In this embodiment of the application, the backup protocol partition address information is preset, for example, the backup protocol partition address information may be address information corresponding to a protocol partition arranged on the first bit in a plurality of protocol partitions, or the backup protocol partition address information may be address information corresponding to any one protocol partition in the plurality of protocol partitions, for example, address information corresponding to a protocol partition arranged on the last bit, or address information corresponding to a protocol partition storing a wireless communication protocol currently configured by the wireless communication apparatus may be used as the backup protocol partition address information, which is not limited in this respect.

In the embodiment of the application, after the logic application detects the wireless communication protocol supported by the household appliance through the model or protocol standard parameters, a target wireless communication protocol to be configured of the wireless communication device can be determined from the communication protocol corresponding to the backup protocol partition address information stored in the electric control module of the household appliance and the plurality of wireless communication protocols corresponding to the plurality of protocol partitions according to the 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, 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.

Specifically, it may be determined whether a wireless communication protocol corresponding to a model or protocol standard parameter exists in a plurality of wireless communication protocols stored in correspondence to the plurality of protocol partitions, and 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. And 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 communication protocol corresponding to the backup protocol partition address information can be used as the target wireless communication protocol.

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 wireless communication protocol currently configured by the wireless communication device is determined to be updated, the logic application in the engineering mode partition is loaded through the bootstrap program in the system-on-chip module, the logic application is used for reading the model or protocol standard parameter of the household appliance and detecting the wireless communication protocol supported by the household appliance through the model or protocol standard parameter, then according to the detection result of the logic application, the target wireless communication protocol to be configured of the wireless communication device is determined from the communication protocol corresponding to the backup protocol partition address information stored in the electric control module of the household appliance and the plurality of wireless communication protocols correspondingly stored in the plurality of protocol partitions, then the loading address information of the bootstrap program is modified into the address information of the target protocol partition corresponding to the stored target wireless communication protocol, and the wireless communication device is restarted, finally, in the process of restarting the wireless communication device, the target wireless communication protocol stored in the target protocol partition is loaded through the bootstrap program, can effectively solve the problems that the prior art realizes the wireless communication among a plurality of protocols by software compatibility with a plurality of protocols, has high software coupling, there may occur technical problems in that protocols of two competing customers are operated at the same time, and that causes an increase in chip resources and an increase in cost, thereby realizing dynamic configuration of wireless communication protocols in the wireless communication device, realizing wireless communication among a plurality of protocols by adopting a partition loading mode, can ensure that the bootstrap program only loads one target wireless communication protocol to operate at the same time, can reduce the requirement on chip resources, thereby reducing the production cost and simultaneously avoiding the situation that the protocols of two mutually competing clients are operated at the same time. In addition, the software coupling can be reduced, and the complexity of protocol function change is reduced, so that the change efficiency is improved.

For clarity of the above embodiment, the embodiment of the present application provides another dynamic configuration method of communication protocol, see

Example 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 invention.

As shown in fig. 4, the method for dynamically configuring a communication protocol may include the following steps:

step 201, when it is determined that the wireless communication protocol currently configured by the wireless communication device is to be updated, determining a protocol partition corresponding to and storing the wireless communication protocol currently configured by the wireless communication device.

Step 202, acquiring address information of a protocol partition corresponding to a wireless communication protocol currently configured by the wireless communication device.

In the embodiment of the application, after the protocol partition corresponding to the wireless communication protocol currently configured by the wireless communication device is determined, the address information of the protocol partition corresponding to the wireless communication protocol currently configured by the wireless communication device may be determined. For example, a correspondence relationship between each protocol partition, the wireless communication protocol stored in the protocol partition, and the address information of the protocol partition may be established in advance, and after the protocol partition of the wireless communication protocol currently configured by the wireless communication apparatus is determined, the correspondence relationship may be queried to acquire the address information corresponding to the protocol partition.

For example, referring to fig. 5, in the embodiment of the present application, a trigger button may be disposed on the household appliance or on a remote controller corresponding to the household appliance, and a user may trigger the household appliance through the trigger button to dynamically configure a wireless communication protocol in the wireless communication device. When the home appliance detects that the user triggers the button (S1), the electronic control module in the home appliance may transmit an instruction to enter an engineering mode, i.e., a detection instruction for a wireless communication protocol supported by the home appliance, to the wireless communication device (S2). When the wireless communication device receives a detection instruction, sent by the household appliance, for a wireless communication protocol supported by the household appliance, it may be determined that the wireless communication protocol currently configured by the wireless communication device is to be updated, and then the wireless communication device may determine a protocol partition corresponding to the wireless communication protocol currently configured by the wireless communication device, and send address information (i.e., address information of the original protocol) corresponding to the protocol partition storing the wireless communication protocol currently configured by the wireless communication device to the electronic control module (S3), and at the same time, may feed back confirmation information to the electronic control module (S4).

Step 203, taking the address information of the protocol partition corresponding to the wireless communication protocol currently configured by the wireless communication device as the backup protocol partition address information, and sending the backup protocol partition address information to the electronic control module for storage.

That is to say, when it is determined that the wireless communication protocol currently configured by the wireless communication device is to be updated, the address of the wireless communication protocol currently used by the wireless communication device may be used as the backup protocol partition address information and sent to the electronic control module for storage, that is, the address of the wireless communication protocol currently used by the wireless communication device is stored in the electronic control module, so that when an abnormal condition occurs in the dynamic configuration process, the backup protocol partition address information may be found from the electronic control module, and thus the wireless communication protocol corresponding to the backup protocol partition address information is loaded for operation, and it is ensured that the wireless communication device can communicate normally.

And step 204, loading the logic application in the engineering mode partition through a bootstrap program in the system-on-chip module, wherein the logic application is used for reading the model or protocol standard parameters of the household appliance.

And step 205, detecting the wireless communication protocol supported by the household appliance through the model or protocol standard parameter.

Referring to fig. 5, address information of the engineering mode partition may be acquired, and the loading address information of the bootstrap program may be modified to address information of the engineering mode partition (S5), and then, the wireless communication device may be restarted (S6), and a logic application in the engineering mode partition corresponding to the modified loading address information is loaded through the bootstrap program (S7), wherein the logic application is configured to send an instruction to read a model or protocol standard to an electronic control module of the home appliance (S8), receive the model or protocol standard returned by the electronic control module (S9), and then, may detect a wireless communication protocol supported by the home appliance through the model or protocol standard.

And step 206, 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 parameters, taking the wireless communication protocol corresponding to the model or protocol standard parameters as a target wireless communication protocol.

And step 207, 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, sending a reading instruction for the backup protocol partition address information to the electronic control module, wherein the reading instruction is used for indicating that the backup protocol partition address information is read from the electronic control module.

And step 208, taking the communication protocol corresponding to the read backup protocol partition address information as a target wireless communication protocol.

Step 209, modify 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 restart the wireless communication device.

Alternatively, when the wireless communication protocol supported by the household appliance is detected by the logic application, it may be determined whether the wireless communication protocol supported by the household appliance is stored in the plurality of wireless communication protocols stored in the plurality of protocol partitions (S10), and if so, that is, when it is determined that the wireless communication protocol supported by the household appliance is stored in the plurality of wireless communication protocols stored in the plurality of protocol partitions, the loading address information of the bootstrap program may be modified to the address information of the target protocol partition (for example, marked as address n), and the wireless communication apparatus may be restarted to configure the communication protocol of the wireless communication apparatus to the wireless communication protocol supported by the household appliance (S11).

If not, that is, when it is determined that there is no wireless communication protocol supported by the home appliance in the plurality of wireless communication protocols stored in the plurality of protocol partitions, configuration failure information may be sent to the electronic control module (for example, the wireless communication device does not support the wireless communication protocol), and an instruction may be sent to the electronic control module to obtain backup protocol partition address information (i.e., a previously backed-up address) (S12), and accordingly, the electronic control module may send the backup protocol address information to the wireless communication device (S13), and then, the wireless communication device may restore the loading address information of the bootstrap program to the previously backed-up address, that is, restore the communication protocol of the wireless communication device to the communication protocol used in the previous configuration, and restart the wireless communication device (S14).
