The utility model content

At the above-mentioned shortcoming of existing twin-power switch controller, the applicant improves through research, and another kind of twin-power switch controller is provided.

The technical solution of the utility model is as follows:

A kind of twin-power switch controller comprises monitoring module and shows the control module;

Described monitoring module is installed within the Switch main body, adopts standardization to be connected with Switch main body; Described monitoring module comprises first CPU, and the voltage, the phase shortage acquisition module that are connected with described first CPU, executive component and the one 485 communication module; Described voltage, phase shortage acquisition module monitor power supply status, the state information of collecting is transferred to described apparent control module by a RS485 communication module after described first central processing unit for processing, and the instruction that receives described apparent control module is by described executive component diverter switch body switching;

Described apparent control module is connected with monitoring module on the Switch main body by the standard USB cable; Described monitoring module comprises second CPU, and the button, the knob that are connected with described second CPU, status indicator LED and the 2 485 communication module; Described the 2 485 communication module receives the power state information of described monitoring module transmission and is sent to second CPU; Under-voltage, the overvoltage of the described second central processing unit controls status indicator LED display power supply, open-phase fault dynamically show twin-power switch switching state; Described button, knob are used to be provided with the parameter and the mode of operation of twin-power switch controller.

Useful technique effect of the present utility model is:

1) the utility model adopts the design of Switch main body and controller monitoring module integral type, only has a USB line that carries out information interaction to exist between the apparent control module of the monitoring module of controller and controller.Line between Switch main body and the monitoring module has become interconnector, production plant's specialty Installation and Debugging by twin-power switch, the user who need not twin-power switch carries out loaded down with trivial details lead connection and school team's work, has avoided unnecessary safety issue, has also reduced the workload of Installation and Debugging.

2) the utility model adopts the mode that dynamically shows to carry out information output to power supply state and twin-power switch operating state, make the Field Force very clear and definite sense organ understanding be arranged, and according to circumstances in time take measures parameter informations such as the overvoltage of the commit condition of switch, power supply, low-voltage, phase shortages.

3) the utility model has the apparent control module of man-machine interaction, can be provided with, revise parameter and the mode of operation and the energy current failure memory of controller flexibly, has improved application range of products and on-the-spot applicability greatly.
