[0079] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0080] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0081] The present application provides a device upgrading method, which is applied to a program upgrading device, such as Figure 1 As shown in the figure, the method comprises:

[0082] Step 101: Obtain multiple candidate baud rates of test data and multiple candidate data frame lengths.

[0083] There is only one master device in the communication network of the RS485 communication unit, and the program upgrading device is only connected when the unit has a program upgrading demand, and the connection is as a slave device. Figure 2 The schematic diagram of the RS485 communication unit network of the air conditioning device is shown, in which the line controller or outdoor unit is the master device.

[0084] When it is necessary to solve the problem by upgrading the program of the device to be upgraded, the technician will store the upgrading program file into the program upgrading device, which can be the program file of a certain type of device to be upgraded, or the program file of multiple types of devices to be upgraded.

[0085] The program upgrading device is connected to the RS485 communication network through communication, obtains the communication parameters of the communication network, including baud rate, polarity, etc. The upgrading tool sends the program upgrading instruction to the RS485 communication network according to the device type of the device to be upgraded, and the device to be upgraded of the device type will feedback its own device address to the RS485 communication network, so as to facilitate the program upgrading device to accurately send the test data and program upgrading segment according to the device address in the future. The program upgrading device selects the upgrading program file required by the device to be upgraded according to the device type of the device to be upgraded.

[0086] The to-be-upgraded device is a controller with an IAP (In Application Programming) function, and the program thereof is composed of two parts, namely, a bootloader and an application part program. The bootloader is a boot loader, controls initialization operation after chip reset, provides a function of programming a Flash memory, and the boot code can reprogram a chip that has been programmed in advance. The application part program implements specific logical functions of the controller.

[0087] The test data needs to be sent at a certain baud rate and a certain data frame length. The program upgrading device first acquires multiple candidate baud rates and multiple candidate data frame lengths of the test data.

[0088] Step 102: According to a preset communication quality test strategy, the optimal test scheme is determined according to the candidate baud rates and the candidate data frame lengths.

[0089] The product of the target baud rate and the target data frame length of the test data in the optimal test scheme is the maximum.

[0090] The program upgrading device determines the target baud rate and the target data frame length according to the preset communication quality test strategy. Among all the candidate baud rates and the candidate data frame lengths, the product of the target baud rate and the target data frame length is the maximum. In this way, the communication efficiency and the data transmission reliability can be considered at the same time.

[0091] Step 103: The program upgrading segment is sent to the to-be-upgraded device at the target baud rate and the target data frame length.

[0092] In the actual program upgrading process, the program upgrading device sends the program upgrading segment to the to-be-upgraded device at the target baud rate and the target data frame length.

[0093] In the present application, the communication quality is tested before the device is upgraded, and the optimal target baud rate and the target data frame length are determined. In the formal device upgrading process, the program upgrading segment is sent at the target baud rate and the target data frame length, so that the communication efficiency and the data transmission reliability can be considered at the same time in the device upgrading process, and the program upgrading efficiency is improved.

[0094] The entire process of the present application is between the program upgrading device and the to-be-upgraded device, and does not need to connect to the Internet and a server, and is particularly suitable for program upgrading of a single-chip microcomputer chip with limited chip resources.

[0095] According to the preset communication quality test strategy, the optimal test scheme is determined according to the candidate baud rates and the candidate data frame lengths, including at least three embodiments.

[0096] For the first embodiment:

[0097] The program upgrading device determines a baud rate-data frame length combination according to the selected baud rate and the selected data frame length. For example, there are three selected baud rates: baudrate1, baudrate2, baudrate3, and three selected data frame lengths: L1, L2, L3, so there are nine baud rate-data frame length combinations: baudrate1-L1, baudrate1-L2, baudrate1-L3, baudrate2-L1, baudrate2-L2, baudrate2-L3, baudrate3-L1, baudrate3-L2, baudrate3-L3.

[0098] Due to the characteristics of the program address space, L1-L3 are preferably multiples of 128, and can also be other values. Here, L1-L3 are the lengths of the data segments of the program file, and the actual data frame needs to add header code, address information, data frame length information, function code, frame code, and check information.

[0099] The program upgrading device sends test data to the device to be upgraded according to each baud rate-data frame length combination. If the response information from the device to be upgraded is received, the product value of the baud rate and the data frame length in the baud rate-data frame length combination corresponding to the response information is selected as the target baud rate and the target data frame length.

[0100] For each baud rate-data frame length combination, n (n>=3) times of test data are sent to the device to be upgraded to improve the test accuracy. If the device to be upgraded does not receive the response information, the baud rate-data frame length combination is directly cancelled.

[0101] For the second embodiment:

[0102] The program upgrading device determines an ordered sequence according to the selected baud rate and the selected data frame length. Each data in the ordered sequence is a baud rate-data frame length combination, and each baud rate-data frame length combination is arranged in order according to the product value of the corresponding selected baud rate and selected data frame length.

[0103] The ordered sequence includes an ascending sequence or a descending sequence. The ascending sequence is determined in order according to the selected baud rate from low to high and the data frame length corresponding to the selected baud rate from short to long. The descending sequence is determined in order according to the selected baud rate from high to low and the data frame length corresponding to the selected baud rate from long to short.

[0104] The program upgrading device selects a middle baud rate-data frame length combination in the ordered sequence, and determines the target baud rate and the target data frame length based on the middle baud rate-data frame length combination.

[0105] If the ordered sequence contains an odd number of combinations, the middle position is the middle baud rate-data frame length combination; if the ordered sequence contains an even number of combinations, any one of the combinations near the middle position is the middle baud rate-data frame length combination.

[0106] Specifically, the program upgrading device sends test data to the device to be upgraded according to the middle baud rate-data frame length combination. For one case, if the program upgrading device does not receive the response information sent by the device to be upgraded, it indicates that the product value of the baud rate and the data frame length in the middle baud rate-data frame length combination is too large, and thus the product value needs to be reduced. Therefore, the program upgrading device selects the adjacent baud rate-data frame length combination of the middle baud rate-data frame length combination in the descending order of the ordered sequence to send test data. If the response information is still not received, the next baud rate-data frame length combination is selected in the descending order to send test data, until the response information is received. Then, the baud rate-data frame length combination corresponding to the response information is the target baud rate and the target data frame length, i.e., the optimal test scheme.

[0107] For another case, if the program upgrading device receives the response information sent by the device to be upgraded, it indicates that the device to be upgraded can use the baud rate-data frame length combination, and the product value of the baud rate and the data frame length can be further increased to achieve better communication efficiency and data transmission reliability. Therefore, the program upgrading device continues to send test data according to the next adjacent baud rate-data frame length combination in the ascending order of the ordered sequence, until the response information is not received. Then, the baud rate-data frame length combination corresponding to the last response information is the optimal test scheme.

[0108] For a third embodiment:

[0109] The program upgrading device determines an ascending sequence according to the order of the low-to-high baud rate, and the short-to-long data frame length corresponding to the same baud rate, wherein each data in the ascending sequence is a baud rate-data frame length combination. The program upgrading device sends test data to the device to be upgraded according to the first baud rate-data frame length combination in the ascending sequence. If the program upgrading device receives the response information sent by the device to be upgraded, it indicates that the product value of the baud rate and the data frame length can be further increased. Therefore, test data is sent to the device to be upgraded according to the next baud rate-data frame length combination. The baud rate-data frame length combination corresponding to the last response information is the optimal test scheme.

[0110] Compared with the first embodiment, the second and third embodiments can only need to send test data according to part of the baud rate-data frame length combinations to determine the optimal test scheme, thereby improving the efficiency of determining the optimal test scheme.

[0111] As an optional implementation, before determining the optimal test scheme according to the selected baud rate and the selected data frame length according to the preset communication quality test strategy, the method further includes: obtaining an initial baud rate of the device to be upgraded, wherein the initial baud rate is different from the selected baud rate; sending a data frame to the device to be upgraded according to the initial baud rate; and if reply information fed back by the device to be upgraded is received within a preset time length, switching the initial baud rate to the selected baud rate.

[0112] When the baud rate changes, the program upgrade device needs to confirm according to the initial baud rate before sending the test data, and the initial baud rate can be the baud rate used by the device to be upgraded in daily work. For example, when the initial baud rate of the slave group is switched to baudrate1, the program upgrade device sends a baud rate data frame at the initial baud rate. After the program upgrade device sends the data frame, a certain time length is reserved to wait for the reply of the device to be upgraded. If the program upgrade device receives the reply information fed back by the device to be upgraded within the preset time length, it indicates that the device to be upgraded can normally communicate, and the initial baud rate is switched to the selected baud rate of the test data, and the communication quality test is started.

[0113] As an optional implementation, the device to be upgraded includes at least one sub-device of the same device type. After sending the program upgrade segment to the device to be upgraded at the target baud rate and the target data frame length, the method further includes: if the upgrade confirmation information fed back by all the sub-devices is not received, the program upgrade segment is re-sent at the target baud rate and the target data frame length; and if the upgrade confirmation information fed back by all the sub-devices is received, the next program upgrade segment is sent at the target baud rate and the target data frame length.

[0114] After the program upgrade device sends the program upgrade segment to the device to be upgraded at the target baud rate and the target data frame length, since the program upgrade segment is sent to multiple sub-devices of the same device type, if the program upgrade device does not receive the upgrade confirmation information fed back by all the sub-devices, it indicates that some sub-devices fail to upgrade, and the program upgrade segment needs to be re-sent at the target baud rate and the target data frame length.

[0115] The to-be-upgraded device receives all program upgrade files, checks for no errors, and then performs erasing, burning, checking, etc. The program upgrade device sends a device start running instruction according to the original machine group communication baud rate, the to-be-upgraded device runs according to the updated program, at this time the program upgrade device exits the master device role, and the original master device is switched from the slave device to the master device role to perform normal communication of the machine group.
