The program upgrading equipment is connected to an RS485 communication network through communication to acquire communication parameters of the communication network, including baud rate, polarity and the like. The upgrade tool sends a program upgrade instruction to the RS485 communication network according to the equipment type of the equipment to be upgraded, and the equipment to be upgraded of the equipment type can feed back the equipment address of the equipment to the RS485 communication network, so that the program upgrade equipment can accurately send test data and program upgrade fragments according to the equipment address.

Step 102: and determining an optimal test scheme according to the to-be-selected baud rate and the to-be-selected data frame length according to a preset communication quality test strategy.
And the product value of the target baud rate of the test data and the target data frame length in the optimal test scheme is the largest.
The program upgrading equipment determines a target baud rate and a target data frame length according to a preset communication quality testing strategy, wherein the product value of the target baud rate and the target data frame length is the largest in all the baud rates to be selected and the data frame length to be selected, and thus the communication efficiency and the data transmission reliability can be simultaneously considered.

The whole process of the application is between the program upgrading equipment and the equipment to be upgraded, the internet and the server are not required to be connected, and the application is particularly suitable for the chip program upgrading of the singlechip with limited chip resources.
The method comprises the steps of determining an optimal test scheme according to a preset communication quality test strategy, a to-be-selected baud rate and a to-be-selected data frame length, and at least three embodiments.
For the first embodiment:
the program upgrading device forms a baud rate-data frame length combination according to the baud rate to be selected and the data frame length to be selected, for example, there are 3 baud rates to be selected: baudrate1, baudrate2, baudrate3,3 candidate data frame lengths: l1, L2, L3, a total of 9 baud rate-data frame length combinations: baudrate1-L1, baudrate1-L2, baudrate1-L3, baudrate2-L1, baudrate2-L2, baudrate2-L3, baudrate3-L1, baudrate3-L2, and Baudrate3-L3.
Because of the characteristics of the program address space, the multiple of L1-L3 is preferably 128, and can also be other values, wherein L1-L3 is the length of a program file data segment, and a header code, address information, data frame length information, a function code, a frame code, check information and the like are required to be added to an actual data frame.
And the program upgrading equipment sends test data to the equipment to be upgraded according to each baud rate-data frame length combination, and if response information of the equipment to be upgraded for the test data is received, the baud rate and the target data frame length with the largest product value of the baud rate and the data frame length are selected from the baud rate-data frame length combination corresponding to the response information.
For each baud rate-data frame length combination, n (n > =3) times of test data are sent to the device to be upgraded, so that the test accuracy is improved. If the equipment to be upgraded does not receive the response information, namely the program receiving upgrading equipment does not receive the response information fed back by the equipment to be upgraded, the baud rate-data frame length combination is directly canceled.
For the second embodiment:
the program upgrading equipment determines an ordered sequence according to the baud rate to be selected and the length of the data frame to be selected, wherein each data in the ordered sequence is a baud rate-data frame length combination, and each baud rate-data frame length combination is orderly arranged according to the product value of the corresponding baud rate to be selected and the length of the data frame to be selected.
The ordered sequence comprises an ascending sequence or a descending sequence, wherein the ascending sequence is determined according to the sequence arrangement of the data frame length corresponding to the one-baud rate to be selected from low to high, and the data frame length corresponding to the one-baud rate to be selected from short to long, and the descending sequence is determined according to the sequence arrangement of the data frame length corresponding to the one-baud rate to be selected from high to low, and the data frame length corresponding to the one-baud rate to be selected from long to short.
The program upgrading device selects an intermediate baud rate-data frame length combination positioned at an intermediate position in the ordered sequence, and determines a target baud rate and a target data frame length by taking the intermediate baud rate-data frame length combination as a starting point.
If the ordered sequence contains odd number of combinations, the most middle position is used as the middle baud rate-data frame length combination; if the ordered sequence contains an even number of combinations, any combination with a nearby middle position is used as the middle baud rate-data frame length combination.
Specifically, the program upgrading device sends test data to the device to be upgraded according to the intermediate baud rate-data frame length combination, and for a situation, if the program upgrading device does not receive response information sent by the device to be upgraded, which indicates that in the intermediate baud rate-data frame length combination, the product value of the baud rate and the data frame length is too large, the product value needs to be reduced, so that adjacent baud rate-data frame length combinations of the intermediate baud rate-data frame length combination are selected to send the test data along the descending direction of the ordered sequence. If the response information is not received, continuously selecting the next baud rate-data frame length combination along the descending order direction to send the test data until the response information can be received, and then the baud rate-data frame length combination corresponding to the response information is the target baud rate and the target data frame length, namely the optimal test scheme.
For another situation, if the program upgrading device receives the response information sent by the device to be upgraded, which indicates that the device to be upgraded can adopt the baud rate-data frame length combination, in order to achieve better communication efficiency and data transmission reliability, the product value of the baud rate and the data frame length can be improved, and then the program upgrading device continues to send test data according to the next adjacent baud rate-data frame length combination along the ascending direction of the ordered sequence until the response information is not received, and then the baud rate-data frame length combination corresponding to the last response information is the optimal test scheme.
For the third embodiment:
the program upgrading device determines an ascending sequence according to the sequence from low to high of the baud rate to be selected and the length of the data frame to be selected corresponding to the same baud rate to be selected from short to long, wherein each data in the ascending sequence is a baud rate-data frame length combination. Starting from the first baud rate-data frame length combination in the ascending sequence, the program upgrading device sends test data to the device to be upgraded according to the first baud rate-data frame length combination. If the program upgrading device receives the response information sent by the device to be upgraded, the program upgrading device can continue to take the product value of the larger baud rate and the data frame length, and then test data is sent to the device to be upgraded according to the next baud rate-data frame length combination, wherein the baud rate-data frame length combination corresponding to the last response information is the optimal test scheme.
Compared with the first embodiment, the optimal test scheme can be determined by sending test data for multiple times according to each baud rate-data frame length combination, the second embodiment and the third embodiment can determine the optimal test scheme by sending test data only according to partial baud rate-data frame length combinations, and the efficiency of determining the optimal test scheme is improved.
As an optional implementation manner, before determining the optimal test scheme according to the to-be-selected baud rate and the to-be-selected data frame length according to the preset communication quality test strategy, the method further includes: acquiring initial baud rate of equipment to be upgraded, wherein the initial baud rate and the baud rate to be selected are different; transmitting a data frame to equipment to be upgraded according to the initial baud rate; and if the reply information fed back by the equipment to be upgraded is received within the preset time, switching the initial baud rate to the baud rate to be selected.
When the baud rate changes, the program upgrading device needs to confirm according to the initial baud rate before sending out test data, and the initial baud rate can be the baud rate adopted by the daily work of the device to be upgraded. For example, when the initial baud rate of the unit is switched to baudrate1, the program upgrading device sends out a baud rate data frame at the initial baud rate, after the program upgrading device sends out the data frame, a certain period of time is reserved for waiting for the upgrading device to answer, if the program upgrading device receives answer information fed back by the equipment to be upgraded in the preset period of time, which indicates that the equipment to be upgraded can normally communicate, the initial baud rate is switched to the baud rate to be selected of test data, and a communication quality test is started.
As an optional implementation manner, after the device to be upgraded includes at least one sub-device of the same device type and the program upgrade fragment is sent 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, retransmitting the program upgrade fragments according to the target baud rate and the target data frame length; and if the upgrade confirmation information fed back by all the sub-equipment is received, transmitting a next program upgrade fragment according to the target baud rate and the target data frame length.
After the program upgrading device sends the program upgrading fragments to the device to be upgraded according to the target baud rate and the target data frame length, the program upgrading device sends the program upgrading fragments to a plurality of sub-devices of the same device type, and if the program upgrading device does not receive upgrading confirmation information fed back by all the sub-devices, which indicates that some sub-devices are failed to upgrade, the program upgrading fragments need to be retransmitted according to the target baud rate and the target data frame length.
And after the equipment to be upgraded receives all the program upgrading files and checks, erasing, burning, checking and the like are performed. The program upgrading equipment sends an equipment starting operation instruction according to the communication baud rate of the original unit, the equipment to be upgraded operates according to the updated program, at the moment, the program upgrading equipment exits the role of the main equipment, and the original main equipment is switched to the role of the main equipment by the slave equipment to perform normal communication of the unit.
