Be further described below with concrete operations example, to the two-way inverter 1 based on Modbus Transmission Control Protocol into
Row charge and discharge control is tested, which includes the following steps：
(1) after ensuring that system wiring is errorless, upper 380V alternating currents, inverter upper left are supplied for 1 exchange side of two-way inverter
Green power supply lamp lights expression normally, opens inverter internal exchange input plug-in strip and direct current output plug-in strip.
(2) in the UI surface charts for the control operation of two-way inverter 1.Configuration interface is first had to, that is, what charge and discharge selected
Pattern has constant current mode, constant voltage mode and constant power mode herein.If selecting constant current mode, charging and discharging currents value is set, this
Place's software has red font prompt " electric discharge is negative, is charged as just ", exchange to have work value, exchange without work value and DC1 performance numbers without spy
It is set as default value 0 in the case of different, therefore the configuration is related to multiple Modbus registers, includes configuration and the electric current of mode register
The configuration of value register, so the setting in " write operation ", without configuration in " writing single ".
(3) after having configured charge and discharge electric condition, send button is clicked, Modbus TCP reports can be shown by sending in message text box
Text, this send message be exactly according in step (1) by UI with postpone organized in BLL layers it is chummy, then using
After DAL layers of network communication interface Socket is transmitted, inverter end Modbus registers are reached, while inverter end also can be immediately
A message is returned as response.
(4) the accurate rear click power on button of message is sent, two-way inverter 1 receives power-on instruction by process as above
Booting task is executed, the constant-current charge task configured in (2) is immediately executed.
(5) charging a period of time, UI power-off buttons are clicked, inverter shutdown stops charging.So far, by being based on C# multilayers
1 control method of two-way inverter of framework completes the action of constant-current charge and shutdown.
Embodiment 2：
Control gathered data is carried out to the terminal device based on Modbus Transmission Control Protocol, shows or calculates for UI, the mistake
Journey includes the following steps：
(1) in the UI surface charts operated for acquisition module.According to the step in embodiment 1, it would be desirable to which parameter read
After message is sent, acquisition module, which can return, carries the Modbus TCP messages of relevant parameter to DAL layers of host computer.
(2) parameter in DAL layers of message is intercepted one by one, and by hexadecimal turn the decimal system parsing after with common parameter PP
The parameter that class defines mutually is bound.
(3) UI layers of reference PP classes, you can call the parameter in PP classes, realize display or calculating of the parameter in UI.
(4) parameter after parsing can be preserved by local Excel or Txt, can also be protected by remote data base SQL Serve
It deposits, convenient for later data processing analysis.
It can be seen that application multi-layer framework programming idea, level is very clear, and parameter transmits safety, and code migrating is convenient easily
It is called in forming method library dll.The involvement for facilitating the update and new equipment of later stage terminal device code, after greatly reducing
Phase maintenance cost and maintenance time.
