[0002] In today's industrial production, the degree of automation is getting higher and higher, and there will be special systems for supporting use. In order to connect different intelligent devices, different communication protocol libraries need to be used. This requires developers to provide a flexible way to allow on-site construction personnel to import different protocol libraries according to the actual situation of the customer. Since the protocol library is relatively complicated and there are many on-site construction situations, remote protocol library upgrades and execution docking have become a very important post-maintenance means.

[0003] In narrow-bandwidth IoT, due to bandwidth limitations, the amount of single data transmission should not be too large. The existing docking includes whole-machine docking and dynamic library docking. Whole-machine docking is not suitable for use in narrow-bandwidth IoT areas because the upgrade package is large and the upgrade time is long. The existing dynamic library docking method is very complicated, and the amount of implementation code is large, which is not suitable for low-cost master control. Summary of the invention

[0040] The following is combined with Figure 1-3 The present invention is further described:

[0041] A protocol library docking execution system suitable for the Internet of Things, comprising a main program module 10, an upgrade platform 20 and a protocol program module 30, wherein the protocol program module 30 is arranged in the main program module 10, and the main program module 10 exchanges information with the upgrade platform 20;

[0042] The main program module 10 includes:

[0043] A data storage area 12 for storing data and a protocol program module 30;

[0044] The execution program module 11 is used to obtain the function address from the protocol library placement interval 121 and execute it,

[0045] The protocol program module 30 includes:

[0046] The protocol main function module 32 is used to store the protocol functions.

[0047] The header module 31 is used to store the addresses of all protocol functions of the protocol program module 30 to call the protocol functions in the protocol main function module 32.

[0048] The data storage interval 12 includes a protocol library storage interval 121 and a miscellaneous storage interval 122.

[0049] The protocol library storage area 121 is used to store the protocol program module 30 and the protocol library data.

[0050] The miscellaneous storage area 122 is used to store miscellaneous data.

[0051] Miscellaneous data includes user configuration data and measurement point data.

[0052] The protocol functions placed in the protocol main function module 32 include a configuration function, a parsing function and several polling functions.

[0053] The data stored in the header module 31 includes the dynamic library version, the number of polling functions, the polling interval, the configuration function address, the parsing function address and several polling function addresses.

[0054] A working method for connecting an IoT protocol library to an execution system:

[0055] A main program module 10 exchanges information with the upgrade platform 20, obtains the protocol file, and sends it to the execution program module 11;

[0056] B execution program module 11 upgrades the protocol library data in protocol library placement interval 121 according to the received protocol file:

[0057] 1.1 Verify the protocol file. If the content of the protocol file is the same as the protocol library data in the protocol library placement interval 121, directly proceed to step C.

[0058] 1.2 Verify the protocol file. If the content of the protocol file is different from the protocol library data in the protocol library placement interval 121, replace the protocol library data with the data in the protocol file, and then proceed to step C;

[0059] C. The main program module 10 connects to the docking device, and the execution program module 11 obtains the configuration function address in the header module 31 and executes the hardware configuration;

[0060] D execution program module 11 obtains the polling function interval and the number of polling function instructions in the header module 31, and calls the polling function in the protocol main function module 32 according to the function address in the header module 31 to obtain a complete polling protocol command, and sends it to the docking device;

[0061] F The docking device receives the complete polling protocol command, and the device performs the polling command operation one by one according to the polling function interval, and sends the executed command response data back to the execution program module 11;

[0062] G execution program module 11 calls the parsing function in protocol main function module 32 according to the received command response data, performs parsing, and generates measurement point data;

[0063] H saves the measurement point data to the miscellaneous placement interval 122.

[0064] The upgrade platform 20 is a software service module responsible for updating protocol files.

[0065] The executive program module 11 provides periodic execution codes.

[0066] The configuration function is used to configure the chip hardware or peripheral hardware. In this embodiment, the baud rate, data bit, stop bit, and check bit of the RS485 serial port are configured.

[0067] The parsing function is used to parse the command response data sent back by the docking device into monitoring point data, for example, voltage: 220V is a monitoring point.

[0068] A monitoring point is a specific monitoring signal on the monitored object, such as voltage, temperature, operating status, etc.

[0069] The polling function obtains the function of the polling command according to the polling interval. For example, if there are three polling commands and the polling interval is 10s, the first polling command is sent to the docking device at the 0th second. The docking device protocol library generates a command response data according to the received command and sends it back to the main program module 10. The main program module 10 calls the parsing function to parse the data to obtain the first measuring point. The second polling command is issued at the 10th second. The second measuring point is obtained by the same process. The third polling command is issued at the 20th second to obtain the third measuring point, and so on. The composition of the complete polling command is very free and flexible.

[0070] The complete polling protocol command is a command set consisting of multiple polling commands and a fixed or fluctuating polling interval setting data.

[0071] The function address is the entry address of the code, which is used to call a specific function.

[0072] The protocol file contains configuration functions, parsing functions, several polling functions, dynamic library version, number of polling functions, polling interval, configuration function address, parsing function address and several polling function addresses. These data are specially prepared for the docking device, that is, the protocol file matches the protocol library of the docking device.

[0073] The key functions of the protocol library program are called through the header. By saving the addresses of all protocol function bodies in the header in sequence, the length of the protocol body function can be changed arbitrarily. The number of protocol body functions can be flexibly changed through the function quantity attribute saved in the attribute.

[0074] In steps 1.1 and 1.2, the verification file is implemented through the CRC component, and the configuration function, parsing function and polling function can use function algorithms that can solve related requirements.

[0075] The key function segments of the configuration function are as follows:

[0076]

[0077]

[0078] The key function segments of the parsing function are as follows:

[0079]

[0080]

[0081]

[0082] The key parts of the polling function are as follows:

[0083]

[0084]

All of these modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
