Detailed Description
To make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 shows a flow chart of an embodiment of the DALI online upgrade method of the present invention, which includes:
s101, when the system receives an upgrade starting instruction sent by a first communication instruction set, exiting the current application program, entering an online upgrade program segment, setting an upgrade flag in the online upgrade program segment, and starting to receive an upgrade transmission instruction sent by a second communication instruction set.
Unlike the prior art, the present invention utilizes a system setup instruction "-136" reserved by the first communication instruction set as an upgrade initiation instruction, where-136, namely: 1111,1111,1000,1000B (0 xff 88).
After the system receives the upgrading starting instruction, the original application program is immediately jumped out, the system enters an independent online upgrading program segment, and meanwhile, an upgrading mark must be set inside the system to start receiving 24-bit upgrading transmission instructions reserved for the second communication instruction set.
It should be noted that the upgrade start instruction is transmitted in a broadcast manner, and must be repeatedly sent within 100ms during normal use, which is highly reliable.
And S102, when the system receives the upgrading transmission instruction, programming the application program according to the content of the upgrading transmission instruction, repeating the steps until a programming finishing instruction in the upgrading transmission instruction is received, stopping receiving the upgrading transmission instruction, clearing the upgrading mark, and starting receiving an upgrading finishing instruction sent by the first communication instruction set.
Unlike the prior art, the present invention utilizes the 24-bit instruction reserved by the second communication instruction set as the upgrade transmission instruction. The upgrade transmission instruction comprises a start address transmission instruction, a data transmission instruction and a programming end instruction, and specifically:
the starting address transmission instruction is used for recording a starting address of a program block to be modified, and comprises three bytes, wherein the first byte is an identification byte, the second byte is a starting address high-order byte, and the third byte is a starting address low-order byte. The first byte is preferably 1111,0001 (0 xf 1).
The data transmission instruction is used for recording the data of the program block to be modified, and comprises three bytes, wherein the first byte is an identification byte, the second byte is a high-order byte of a data word, and the third byte is a low-order byte of the data word; the first byte is preferably 1111,0101 (0 xf 5). In the transmission process, when the second communication instruction set sends the upgrading transmission instruction, the initial address transmission instruction is sent firstly, and the data transmission instruction can be sent repeatedly until all the contents on the program block to be modified are sent in sequence.
The programming ending instruction is used for indicating that programming of the program block to be modified is completed, and comprises three bytes, wherein the first byte, the second byte and the third byte are identification bytes. The first byte is preferably 1111,0111 (0 xf 7), the second byte is preferably 0xaa, and the third byte is preferably 0x55.
It should be noted that, after the system receives the programming end instruction in the upgrade transmission instruction, the system immediately stops receiving the 24-bit upgrade transmission instruction in the second communication instruction set, and converts the 24-bit upgrade transmission instruction into a 16-bit upgrade completion instruction in the first communication instruction set. That is, after receiving the programming end instruction in the upgrade transmission instruction, the system waits for receiving the upgrade completion instruction, and when receiving the upgrade completion instruction, exits from the "online upgrade" state and enters into the new programming application program.
Further, the upgrade transmission instruction also comprises a total byte number instruction used for recording the total byte number to be transmitted by the program block to be modified. The total byte number instruction comprises three bytes, wherein the first byte is an identification byte, the second byte is a high-order byte of the total byte number, and the third byte is a low-order byte of the total byte number. The first byte is preferably 1111,0011 (0 xf 3).
It should be noted that the total byte number refers to the program byte in the program block, and does not include the start address and the total byte number itself, and usually a program block is 64 bytes or an integer multiple thereof, if it is standard 64 bytes, the total byte number instruction may not be sent.
S103, after the system receives the upgrade completion instruction, all upgrade information in the online upgrade program segment is cleared, and a newly programmed application program is entered.
Unlike the prior art, the present invention utilizes a system setup instruction "-137" reserved by the first communication instruction set as an upgrade complete instruction, where-137, i.e.: 1111,1111,1000,1001B (0 xff 89).
It should be noted that the upgrade start instruction and the upgrade complete instruction are transmitted in a broadcast manner, and must be repeatedly transmitted within 100ms during normal use.
Further, the method for entering the newly-programmed application program comprises the following steps: and entering a newly-programmed application program through a soft reset method.
After the system receives the upgrade complete instruction, all upgrade information in the online upgrade program section in the online upgrade process is immediately cleared, and the newly programmed application program is initialized immediately by a soft reset method.
Therefore, the invention redefines the DALI online upgrading instruction (such as the upgrading starting instruction, the starting address transmission instruction, the total byte number instruction, the data transmission instruction, the programming ending instruction and the upgrading finishing instruction) by using the instruction reserved in the first communication instruction set and the second communication instruction set but not used, thereby expanding and supplementing the DALI function, realizing the online upgrading based on the DALI and having strong practicability and flexibility. Meanwhile, the invention adopts a system setting instruction '-136' reserved by the first communication instruction set (DALI 1) as an upgrade starting instruction and '-137' as an upgrade completing instruction, and borrows a 24-bit instruction reserved by the second communication instruction set (DALI 2) as an online upgrade data transmission instruction, thereby ensuring that the upgrade instruction type is consistent with the reserved instruction type, reducing the change of the instruction and being more convenient to operate.
Referring to fig. 2, fig. 2 shows a specific structure of the DALI online upgrade system 100 of the present invention, which includes an upgrade starting module 1, an upgrade transmitting module 2, and an upgrade completing module 3.

The invention utilizes a system setting instruction '-136' reserved by a first communication instruction set as an upgrading starting instruction, wherein, 136 is: 1111,1111,1000,1000B (0 xff 88).
It should be noted that the upgrade start instruction is transmitted in a broadcast manner, and must be repeatedly transmitted within 100ms during normal use.
2. Upgrading the transmission module:
the upgrading transmission module 2 is configured to receive an upgrading transmission instruction sent by a second communication instruction set, and when the upgrading transmission instruction is received, program the application program according to the content of the upgrading transmission instruction, repeat the above steps until a programming end instruction in the upgrading transmission instruction is received, stop receiving the upgrading transmission instruction, and drive the upgrading completion module 3.
The present invention utilizes the 24-bit command reserved by the second communication command set as an upgrade transfer command. The upgrade transmission instruction comprises an initial address transmission instruction, a total byte number instruction, a data transmission instruction and a programming end instruction, and specifically:
the starting address transmission instruction is used for recording a starting address of a program block to be modified, and comprises three bytes, wherein the first byte is an identification byte, the second byte is a starting address high-order byte, and the third byte is a starting address low-order byte. The first byte is preferably 1111,0001 (0 xf 1).
The total byte number instruction is used for recording the total byte number to be transmitted by the program block to be modified, and comprises three bytes, wherein the first byte is an identification byte, the second byte is a high-order byte of the total byte number, and the third byte is a low-order byte of the total byte number. The first byte is preferably 1111,0011 (0 xf 3). It should be noted that the total byte number refers to the program byte in the program block, and does not include the start address and the total byte number itself, and usually a program block is 64 bytes or an integer multiple thereof, if it is standard 64 bytes, the total byte number instruction may not be sent.
The data transmission instruction is used for recording the data of the program block to be modified, and comprises three bytes, wherein the first byte is an identification byte, the second byte is a high-order byte of a data word, and the third byte is a low-order byte of the data word; the first byte is preferably 1111,0101 (0 xf 5). In the transmission process, when the second communication instruction set sends the upgrading transmission instruction, the initial address transmission instruction is sent firstly, and the data transmission instruction can be sent repeatedly until all the contents on the program block to be modified are sent in sequence.
The programming ending instruction is used for indicating that programming of the program block to be modified is completed, and comprises three bytes, wherein the first byte, the second byte and the third byte are identification bytes. The first byte is preferably 1111,0111 (0 xf 7), the second byte is preferably 0xaa, and the third byte is preferably 0x55.
3. Upgrade completion module
And the upgrading completion module 3 is used for receiving an upgrading completion instruction sent by the first communication instruction set, clearing all upgrading information in the online upgrading program segment after receiving the upgrading completion instruction, and entering a newly written application program.
The invention utilizes a system setting instruction '-137' reserved by a first communication instruction set as an upgrade completion instruction, wherein, -137 is that: 1111,1111,1000,1001B (0 xff 89).
It should be noted that the upgrade start instruction and the upgrade complete instruction are transmitted in a broadcast manner, and must be repeatedly transmitted within 100ms during normal use.
In the online upgrading process, after receiving an upgrading starting instruction sent by a first communication instruction set, an upgrading starting module 1 immediately jumps out of an original application program and enters an independent online upgrading program segment, and meanwhile, an upgrading mark is required to be arranged inside the upgrading starting module, and then an upgrading transmission module 2 is started to start to receive a 24-bit upgrading transmission instruction reserved for a second communication instruction set. When the upgrade transmission module 2 receives the upgrade transmission instruction, the application program is programmed according to the upgrade transmission instruction, and meanwhile, after the upgrade transmission module 2 receives a programming end instruction in the upgrade transmission instruction, the 24-bit upgrade transmission instruction of the second communication instruction set stops being received immediately, and meanwhile, the upgrade completion module 3 is driven to receive the upgrade completion instruction of the first communication instruction set. After receiving the upgrade complete instruction, the upgrade complete module 3 immediately clears all upgrade information in the online upgrade program segment in the online upgrade process, and immediately initializes and enters the newly programmed application program by a soft reset method.
Therefore, the invention can effectively realize the DALI-based online upgrade, thereby expanding and supplementing the DALI function and having strong practicability and flexibility.
Correspondingly, the invention also provides computer equipment which comprises a memory and a processor, wherein the memory stores a computer program, and the processor realizes the steps of the DALI online upgrading method when executing the computer program.
