Support the communication simultaneously between multiple host computer servers；Transparent transmission instruction or concentration upload data to host computer service
Device or third party's energy consumption platform；It supports the preservation of historical data and resumes, data space can be defined, it is empty beyond storage
Between, data scrolling is removed and is saved.
(2) transparent transmission and data are saved
Normal operating condition: each port of gateway is as an independent TCPClient client, with host computer server-side
Establish connection.Each port keeps a long connection, and timing reporting port ID (heartbeat), and port id is configurable.Main website receives
After heartbeat packet, heartbeat is responded immediately, and gateway judges whether normal operation according to response.Under normal condition, main website issues acquisition and refers to
Order/control instruction is transparent to corresponding port, and in the instrument issued, the data that instrument returns are transparent to upper computer software.This
Process gateway does not save data.
Connection abnormality: gateway and main website server disconnection TCP connection be not alternatively, transmission heartbeat receives response, even
Continuous retransmit 3 times is not all responded, then labeled as connection abnormality.Abnormality is connected, gateway enters automatic collection mode, root
According to equipment configured in gateway and the corresponding meter reading instruction of each equipment, automatic copy reading data are carried out, and save data, number
According to being not processed.Each meter reading all saves.
Connection restores normal: gateway and host computer server restore connection, and can receive heartbeat response, gateway again into
Enter normal operating condition, historical data is reported toward host computer server frame by frame (data include meter reading instruction, response data and
Storage time).Data report rule: reporting historical record when being not received by host computer instruction.Gateway answers priority processing master
The instruction that station issues.Evacuation reports historical data；After main website receives historical data, responds receive successfully immediately.Gateway receives master
It stands after response, removes the historical record that this has reported, continue to repeat historical record if without responding.
(3) communications protocol is arranged
Configure device protocol (Modbus-RTU, DL/T 645-1997, DL/T 645-2007, the CJ/T 188- of gateway
2004, IEC101/104 agreement), or use customized communications protocol.
The present invention must not adapt to the application scenarios of most power industry by connected applications multi-protocol interface, solution
Technical problem, to support the agreement of perfect power industry, can flexible custom protocol, and then realize using operation more
It is convenient.
Particular embodiments described above has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that the above is only a specific embodiment of the present invention, the protection being not intended to limit the present invention
Range.It particularly points out, to those skilled in the art, all within the spirits and principles of the present invention, that is done any repairs
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
