[0059] Aspects of the present invention are described below with reference to the accompanying drawings.

[0060] like Figure 1 As shown, an exemplary embodiment of the present invention provides a method for reading historical records of a generator set controller, comprising the following steps:

[0061] S1. The generator set controller allocates a MODBUS address for the historical record data. The MODBUS address includes the total number of addresses, the address of the current record to be read, and the address of the historical record data content.

[0062] Optionally, the total number of addresses, the address of the number of entries currently to be read, and the address of the content of the historical record data are allocated in this order, and each address uses a certain number of holding registers.

[0063] Among them, the historical record data content address includes event type address, event item address, time address, power generation information address, load information address, AC information address and engine information address. The above addresses are also allocated in sequence, and each address uses a certain number of holding registers.

[0064] The total number of addresses, the address of the current number to be read, the event type address, and the event item address each occupy a holding register, the time address occupies 6 holding registers, the power generation information address occupies 7 holding registers, the load information address occupies 4 holding registers, and the AC power information address occupies 7 holding registers; the "event type" includes: 0, power on / off event; 1, shutdown alarm event; 2, tripping shutdown event; 3, tripping alarm event; and the "event item" is a specific item under a certain "event type".

[0065] S2. The host computer reads the total number of addresses through the MODBUS protocol and records the total number of historical record data. The total number is a natural number greater than or equal to 1. The 03 function code in the MODBUS protocol is used to read the "total number".

[0066] S3. The host computer writes the serial number of the record to be read to the address of the record to be read through the MODBUS protocol. The serial number is a natural number between 1 and the total number of records, representing which historical record the host computer needs to read. The serial number of the record to be read uses the 06 function code in the MODBUS protocol.

[0067] S4. The generator controller updates the data content corresponding to the serial number in the historical record to the historical record data content address according to the serial number written by the host computer; the generator controller updates the data by traversing the historical record to find the data content corresponding to the written serial number, and updates the data to the historical record data content address. Optionally, the event type address, event item address, time address, power generation information address, load information address, mains information address, and engine information address are updated respectively.

[0068] Step S4 is the generator set controller responding to the upper computer's operation of reading historical records. Normally, the serial number written does not exceed the total number of records. If the serial number in the address of the current record to be read is greater than the total number of historical records, no response will be given, and then step S3 will be repeated to rewrite the serial number of the current record to be read.

[0069] S5. The host computer reads the updated historical record data content address through the MODBUS protocol and records the updated historical record data content. The written sequence number is matched with the updated historical record data content to form a complete historical record data, thus completing the reading of a historical record data.

[0070] S6. Continue to read the next historical record, and repeat steps S3-S5 until all the records are read.

[0071] As an example, the total number of historical record data read and recorded by the host computer is 10. The host computer writes the serial number 1 to the address of the current record to be read through the MODBUS protocol, and the generator set controller updates the content of the first historical record data in the historical record to the historical record data content address. Then the host computer reads and records the updated historical record data content through the MODBUS protocol, and the reading of the first historical record data is completed. Then the host computer can write serial number 2, and complete the reading of the second historical record data in the same way; repeat this until the reading of 10 historical record data is completed. The serial numbers written by the host computer can be written in order from large to small or from small to large, or they can be written randomly, as long as the total number of records is read. Preferably, the written serial numbers are written in order from large to small or from small to large.

[0072] This application implements the reading of historical records of generator set controllers based on the MODBUS protocol, realizes data synchronization between the host computer and the generator set controller, and solves the problem of a wide variety of interfaces and protocols for reading historical record data of generator set controllers in the current industry. It has strong versatility, low maintenance cost, is easy for secondary development, and has simple logic, high-speed communication, and high reliability.

[0073] like Figure 2 As shown, an exemplary embodiment of the present invention provides a method for reading historical records of a generator set controller, the method comprising:

[0074] S1', the generator set controller allocates a MODBUS address for the historical record data. The MODBUS address includes the total number of addresses, the address of the current record to be read, the address of the current record to be updated, and the address of the content of the historical record data.

[0075] Optionally, the total number of addresses, the address of the number of entries currently to be read, the address of the number of entries currently updated, and the address of the content of the historical record data are allocated in this order, and each address uses a certain number of holding registers.

[0076] Among them, the historical record data content address includes event type address, event item address, time address, power generation information address, load information address, AC information address and engine information address. The above addresses are also allocated in sequence, and each address uses a certain number of holding registers.

[0077] The total number of addresses, the address of the current number to be read, the address of the current number to be updated, the event type address, and the event item address each occupy a holding register, the time address occupies 6 holding registers, the power generation information address occupies 7 holding registers, the load information address occupies 4 holding registers, and the AC power information address occupies 7 holding registers; the "event type" includes: 0, power on / off event; 1, shutdown alarm event; 2, tripping shutdown event; 3, tripping alarm event; and the "event item" is a specific item under a certain "event type".

[0078] S2', the host computer reads the total number of addresses through the MODBUS protocol and records the total number of historical records. Reading the "total number" uses the 03 function code in the MODBUS protocol.

[0079] S3', the host computer writes the serial number of the record to be read to the address of the record to be read through the MODBUS protocol. The serial number is a natural number between 1 and the total number of records; it represents which historical record the host computer needs to read. The serial number of the record to be read uses the 06 function code in the MODBUS protocol.

[0080] S4', the generator set controller updates the data content corresponding to the serial number in the historical record to the historical record data content address according to the serial number written by the host computer, and updates the data in the address of the current update to the serial number corresponding to the data content in the historical record data content address.

[0081] Step S4' is the generator set controller responding to the operation of the host computer reading the historical records. Usually, the serial number written does not exceed the total number of records. The generator set controller updates the data by traversing the historical records to find the data content corresponding to the written serial number, and updates the data to the historical record data content address, and correspondingly updates the serial number corresponding to the historical data content to the address of the currently updated record to ensure the integrity of the data. If the serial number in the address of the record to be read is greater than the total number of historical records, no response will be given, that is, if the generator set controller traverses the historical records and fails to retrieve the historical record data content corresponding to the written serial number, the historical record data content address will not be updated, nor will the data in the address of the currently updated record be updated, so as to prompt the host computer that the record is damaged or does not exist; then continue to repeat step S3' and rewrite the serial number of the record to be read.

[0082] S5', the host computer determines whether the data content in the historical record data content address is updated by comparing the current serial number in the currently updated address (i.e., the serial number in the currently updated address after the update in step S4') with the serial number of the address currently to be read written by the host computer in step S3', and records the update result; specifically including:

[0083] The host computer reads the current serial number in the address of the currently updated record through the MODBUS protocol, and compares the serial number with the serial number of the address of the currently to be read record written by the host computer in step S3'. If they are consistent, the updated historical record data content address in step S4' is read and the historical record data content of this update is recorded, indicating that the historical record has been read and is a complete historical record; if they are inconsistent, this step is repeated. If there is still inconsistency after repeating the preset number of times (preferably three times), it means that the historical record may be damaged, and the host computer records that the reading of this historical record has failed.

[0084] By comparing the data in the address currently being updated with the data in the address currently being read, it is determined whether the data in the historical record data content address has been updated, thereby achieving synchronization between the generator set controller and the host computer data and ensuring the integrity of the historical record data reading.

[0085] S6', continue to read the next historical record, and repeat steps S3'-S5' until all the records are read.

[0086] As an example, the total number of historical record data read and recorded by the host computer is 10. The host computer writes the serial number 1 to the address of the current record to be read through the MODBUS protocol. The generator set controller updates the content of the first historical record data in the historical record to the address of the historical record data content. Then the host computer reads and records the content of the historical record data updated this time through the MODBUS protocol. After the historical record data is updated, the actual serial number corresponding to the content of the historical record data is used as the current serial number in the address of the current update to update the address of the current update; then a comparison is performed. If the updated serial number in the address of the current update is 1, which is consistent with the written serial number 1, it indicates that the target read historical record data content is consistent with the actual read historical record data content, and the historical record data content is updated, and the reading of the first historical record data is completed. If the updated serial number in the address of the current update is other than 1, that is, the actual serial number corresponding to the data content updated to the address of the historical record data content is not necessarily the same as the serial number to be written, it indicates that the target updated historical record data content is not the same as the actual updated historical record data content, and the historical record is damaged. The integrity of the historical record data is verified by comparison. Then the host computer can write serial number 2 and complete the reading of the second historical record data in the same way; repeat this process until the reading of 10 historical record data is completed.

[0087] An exemplary embodiment of the present invention provides a generator set controller history record reading device 1100, such as Figure 3 As shown, including:

[0088] The first address allocation module 1101 is used for the generator set controller to allocate MODBUS addresses for historical record data.

[0099] The second update result recording module 1105' is used by the host computer to determine whether the data content in the historical record data content address has been updated by comparing the current serial number in the address of the current update with the serial number of the address of the current read written by the host computer, and record the update result;

[0100] The second loop module 1106' is used to continue reading the next historical record and control the second read sequence number writing module, the historical record data content and sequence number updating module and the second update result recording module to execute repeatedly.
