DEVID=123456&data

Note: The data format sent by the device to the server is DEVID=123456&data=xxxxxxxxx

The data format issued by the server should be
data=xxxxxxxxx

XXXXXXXXX is hexadecimal data in ASCII format.

E.g:

Device raw data 0x55 0x03 0x05 0x62 0x00 0x0D 0x28 0xC9

Device HTTP data DEVID=123456&data=55030562000D28C9

If the device resolves that the data does not satisfy data = xxxxxxxxx, it

will directly discard it. If it is satisfied and the address code is the device's

own address code, perform the corresponding operation; if it is satisfied but

the address code is not the device's own address code, it will be sent to the

RS485 network.
