[0034] Following, the advantages and effects of the present application will be described in detail with specific embodiments. Other advantages and effects of the present application can be easily understood by those skilled in the art from the description. The present application can also be implemented or applied in other different embodiments, and the details in the description can be modified or changed based on different views and applications without departing from the spirit of the present application. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application, and the figures only show the components related to the present application, not the number, shape and size of the components when actually implemented. The shape, number and proportion of each component can be arbitrarily changed when actually implemented, and the layout pattern of the components can be more complex.

[0036] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details, and in other embodiments, the well-known structures and devices are shown in the form of block diagrams rather than in the form of details to avoid making the embodiments of the present application difficult to understand.

[0037] The main drive system of the SL150 generally refers to the core power transmission device of a certain equipment (such as a rolling mill, a shearing machine, etc.).

[0038] TDC (Teleperm D Digital Control) is a high-performance and high-reliability industrial automation controller launched by Siemens, mainly for complex process control and large industrial systems (such as power, metallurgy, chemical industry, papermaking, etc.).

[0039] AC-AC frequency conversion is a technology that directly converts fixed frequency and fixed voltage AC power into variable frequency and variable voltage AC power without passing through a DC intermediate link.

[0040] Unix system is a multi-user and multi-task operating system (OS), which is known for its stability, security, portability and modular design.

[0041] Currently, there are many problems in time synchronization in the equipment using a specific control system (for example: SIMADYND) and a SL150 main drive system. When the main drive system appears an alarm and a fault information, if the displayed time is error data, the maintenance personnel is difficult to determine the accurate time of the fault according to the error time information, and the fault elimination lacks effective guiding significance, so that the maintenance personnel cannot timely and accurately understand the time sequence and related conditions of the fault, resulting in low fault disposal efficiency, increasing the production interruption time and cost.

[0042] In the prior art, the time of the main drive system mainly depends on manual setting, but the manual setting mode needs to use a programmed computer, and the computer system is a unix system in the early 1970s, which increases the complexity of manual operation, and most of the maintenance personnel are not familiar with the start and shutdown steps of the unix system. In addition, the manual setting of the time also needs to modify the program, and the professional requirements of the maintenance personnel are higher. After each maintenance and restart of the system controller, the time needs to be manually set again, and the frequent manual setting of the time also increases the maintenance cost and workload, and reduces the reliability and stability of the system.

[0043] To solve the above problems, as shown in Figure 1 The application provides a time synchronization method of a main drive control system, which at least includes steps S110-S150:

[0044] S110: obtaining a standard time.

[0045] Specifically, the TDC controller in the SIMADYND system obtains the standard time sent by an external process control system, and the standard time is transmitted in a 6-word data format and contains time sequence information of year, month, day, hour, minute and second; the standard time can adopt a local time reference based on a geographical time zone, and the standard time includes but is not limited to Beijing time (UTC+8), Tokyo time (UTC+9) or Seoul time (UTC+9) and the like. The driving mode of the main drive control system includes but is not limited to AC-AC frequency conversion.

[0046] S120: performing first-level byte processing on the standard time to obtain date bytes and time bytes.

[0047] In detail, the standard time includes year information, month information, day information and time information, the first-level byte processing is performed on the standard time to obtain the date bytes and the time bytes, including: performing century removal processing and byte splitting on the year information to obtain year split bytes; respectively performing byte splitting on the month information, the day information and the time information to obtain month split bytes, day split bytes and time split bytes; performing byte reorganization on the year split bytes, the month split bytes, the day split bytes and the time split bytes to obtain the date bytes and the time bytes. Specifically, as shown in Figure 2As shown, the year information in the standard time is subtracted by the year at the beginning of this century to obtain the year number of this century, for example: the year information is 2024, the year information is subtracted by 2000 to obtain the year number of this century as 24, the year number of this century is split into high and low bytes by the splitting function (W_BY) of the first preset byte processing block to obtain the year split byte 0018. The month information 5, the day information 20 and the time information 15 are byte split into month split byte, day split byte and time split byte by the splitting function (W_BY) of the first preset byte processing block, the month split byte is 0005, the day split byte is 0014, and the time split byte is 000F. The year split byte, the month split byte, the day split byte and the time split byte are reorganized to obtain the date byte and the time byte; wherein the encoding mode of the year split byte, the month split byte, the day split byte and the time split byte is hexadecimal.

[0048] More specifically, the year split byte, the month split byte, the day split byte and the time split byte are byte reorganized to obtain the date byte and the time byte, including: the low byte of the year split byte is taken as the high byte of the date byte, the low byte of the month split byte is taken as the low byte of the date byte, and the date byte is reorganized; the low byte of the day split byte is taken as the high byte of the time byte, and the low byte of the time split byte is taken as the low byte of the time byte, and the time byte is reorganized. Specifically, as shown, Figure 3 The low byte 18 of the year split byte is taken as the high byte, the low byte 05 of the month split byte is taken as the low byte, and the low byte 18 of the year split byte and the low byte 05 of the month split byte are combined by the combination function (BY_W) of the first preset byte processing block to obtain the date byte 1805; as shown, Figure 4 The low byte 14 of the day split byte is taken as the high byte, the low byte 0F of the time split byte is taken as the low byte, and the low byte 14 of the day split byte and the low byte 0F of the time split byte are combined by the combination function (BY_W) of the first preset byte processing block to obtain the time byte 140F.

[0049] In detail, before the date byte and the time byte are transmitted to the main drive control system, including: converting the encoding mode of the date byte and the time byte, so that the converted date byte and the time byte are consistent with the target encoding mode of the receiving end of the main drive control system. Specifically, before the date byte and the time byte are transmitted to the main drive control system, the date byte 1805 is converted from the encoding mode of 16 to the encoding mode of 10 to obtain the date byte of 10 as 6149, and the time byte 140F is converted from the encoding mode of 16 to the encoding mode of 10 to obtain the time byte of 10 as 5136; so that the target encoding mode of the receiving end of the main drive control system is the same when the date byte of 10 6149 and the time byte of 10 5136 are sent.

[0050] S130: transmit the date byte and the time byte to the main drive control system, and the main drive control system performs second-level byte processing on the date byte and the time byte to obtain time synchronization information.

[0051] As shown in Figure 5 , the decimal date byte 6149 and the time byte 5136 are sent to the main drive control system whose target coding mode is decimal.

[0052] In detail, the main drive control system performs second-level byte processing on the date byte and the time byte to obtain time synchronization information, including: the main drive control system splits the date byte and the time byte into four different single bytes; each single byte is combined with a preset threshold high byte to obtain time synchronization information. Specifically, as shown in Figure 6 , when the main drive control system receives the date byte and the time byte, the date byte is split into two bytes by the splitting function (SWB) of the second preset byte processing block T10, and the time byte is split into two bytes by the splitting function (SWB) of the second preset byte processing block T20. The first single byte split from the date byte is combined with the preset threshold high byte 0H0 by the combining function (SBW) of the second preset byte processing block T12 to obtain the year word in the time synchronization information; the second single byte split from the date byte is combined with the preset threshold high byte 0H0 by the combining function (SBW) of the second preset byte processing block T14 to obtain the month word in the time synchronization information; the first single byte split from the time byte is combined with the preset threshold high byte 0H0 by the combining function (SBW) of the second preset byte processing block T22 to obtain the day word in the time synchronization information; and the second single byte split from the time byte is combined with the preset threshold high byte 0H0 by the combining function (SBW) of the second preset byte processing block T24 to obtain the hour word in the time synchronization information.

[0053] In detail, after obtaining the time synchronization information, it further includes: calling a time configuration module in the main drive control system, inputting the time synchronization information into the corresponding pin of the time configuration module, and initializing the time configuration module. Specifically, as shown in Figure 6 , after obtaining the four bytes of the time synchronization information, the time configuration module RTCM in the main drive control system is called, as shown in Figure 7As shown, the year character in the time synchronization information is transmitted to the year pin XYR of the time configuration module RTCM through the first transmission unit NSW (T32), the month character in the time synchronization information is transmitted to the month pin XMD of the time configuration module RTCM through the second transmission unit NSW (T34), the day character in the time synchronization information is transmitted to the day pin XDA of the time configuration module RTCM through the third transmission unit NSW (T36), the hour character in the time synchronization information is transmitted to the hour pin XHR of the time configuration module RTCM through the fourth transmission unit NSW (T38), and the minute pin XM1 in the time configuration module RTCM is set to zero.

[0054] S140: When the hour word in the time synchronization information changes, a time synchronization enable signal is generated.

[0055] Specifically, such as Figure 8 As shown, when the hour word in the time synchronization information is sent to the hour input pin XHR of the time configuration module RTCM via the fourth transmission unit NSW (T38), a clock monitoring unit ETW.C is also set between the fourth transmission unit NSW (T38) and the enable pin IS of the time configuration module RTCM. The data input pin of the clock monitoring unit ETW.C is connected to the output terminal of the fourth transmission unit NSW (T38), the function control pin of the clock monitoring unit ETW.C is OHFFFF, and the output terminal of the clock monitoring unit ETW.C is connected to the enable pin IS of the time configuration module RTCM. The clock monitoring unit ETW.C monitors the changes in the hour word in real time. When the hour word changes, for example, from 14 to 15, the clock monitoring unit ETW.C detects the change in the hour and outputs a pulse, which is the time synchronization enable signal.

[0056] S150: Time synchronization of the main drive control system based on the time synchronization enable signal.

[0057] Specifically, such as Figure 8 As shown, the output of the clock monitoring unit ETW.C sends the time synchronization enable signal to the enable terminal of the time configuration module RTCM. At this time, the clock configuration pin of the system time configuration block of the time configuration module RTCM is connected to the external clock configuration D01_P1 to perform time synchronization operation on the system time of the main drive control system, ensuring that the time of the main drive control system is consistent with the standard time.

[0058] It needs to be emphasized that after the time synchronization of the main drive control system is completed, the clock monitoring unit ETW.C will output a time synchronization enable signal once the hour word changes every hour, and the time configuration module RTCM is updated once for time synchronization, further ensuring the accuracy and timeliness of time synchronization, and avoiding the problem of time asynchronization caused by data transmission delay or interference.

[0059] In an embodiment of the present application, as shown in Figure 8 , the time configuration module RTCM synchronized time is format converted by the clock output unit RTC003(LTC2) and output to the control panel, as shown in Figure 9 , after the time synchronization of the main drive control system, the time displayed on the control panel is correct after the alarm occurs.

[0061] The acquisition module 1001 is configured to obtain a standard time.

[0062] The first byte processing module 1002 is configured to perform first-level byte processing on the standard time to obtain a date byte and a time byte.

[0065] The clock synchronization module 1005 is configured to synchronize the time of the main drive control system based on the time synchronization enable signal.
