Close the elementary key name of JSON data formats；The status data of the electrical equipment is converted to and meets the elementary of JSON data formats
Key assignments.
Still so that electrical equipment 220 elects header box as an example, then accommodation is the device name " header box " of header box
Meet the elementary key name of JSON data formats, i.e. " Junctionboxdata ".Header box includes multiple item names, these classes
Alias, which claims, to be arranged side by side and is respectively provided with categorical data, and these data need independent description, could correctly show the work of header box
State.
In embodiments of the present invention, data converting 20 is additionally operable to so that the status data with multiple categorical datas to be turned
It is changed to elementary key assignments.Specifically, data converting 20 is used to be converted to the item name of the electrical equipment to meet JSON
The nested key name of data format；The status data of the electrical equipment is converted to the nested key assignments for meeting JSON data formats；
According to the nested key name and nested key assignments, elementary key assignments is generated.Elementary key assignments now is embedded to be cased with multiple array objects.
Still so that electrical equipment 220 elects header box as an example, " DC voltage 1 " is converted to meets JSON data lattice to item name
The nested key name of formula, i.e. " votage1 ".Magnitude of voltage as categorical data is directly as the nested key assignments for corresponding to nested key name.
Finally, data converting 20 generates target data according to the elementary key name and elementary key assignments.Target data is
To meet the code of JSON data formats.
Photovoltaic monitoring data in table 1 can be then still converted to by number of targets with data instance in table 1, data converting 20
According to specifically as shown in Table 2 above.
Data transmitter part 30 is used to transmit target data to target terminal 300.
Target data is presented as the code for meeting JSON data formats, for example, by the ICP/IP protocol of high reliability by mesh
Data transfer is marked to target terminal.In actual applications, can be using for example " with the positive acknowledgment retransmitted ", technology passes to realize
Defeated reliability, the packet loss occurred in transmitting procedure, wrong the problems such as wrapping, similarly possess the mechanism such as error correction, repeating transmission.Application layer
What agreement was then taken is the HTTP POST agreements of high security, POST be the data of submission are then placed on be HTTP bags bag
In body, it is not easy to be intercepted or is attacked.
In embodiments of the present invention, target terminal 300 can elect the destination server with data-handling capacity as, the mesh
