Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is the theory diagram of the utility model wireless control system.
Embodiment
As shown in figure 1, a kind of wireless control system of remote control combining inverter of the present utility model, including:
The self-resetting type over-and under-voltage protector 110 of self-resetting type over-and under-voltage protector 110 is with over-and under-voltage protection and certainly Dynamic reset function;For protecting AC power supplies 70, GSM controllers 60, combining inverter 10, alternating current-direct current air switch divide-shut brake control Device processed is not caused instantaneously voltage rise to influence this control system by electric network fault or thunder and lightning;
Combining inverter 10, the combining inverter 10 are used to direct current caused by solar cell panel assembly 20 being converted into The alternating current for meeting utility grid requirement is directly accessed public electric wire net after this;And combining inverter 10 can be by power setting all the way Or the solar cell panel assembly 20 that multiple access direct current generates electricity by way of merging two or more grid systems;
Alternating current air switch 30, the alternating current air switch 30 are connected on self-resetting type over-and under-voltage protector side and parallel network reverse The exchange outlet side of device 10, and the alternating current air switch 30 is provided with the auxiliary closure motor 40 that can drive its divide-shut brake;Civil power During suspension, alternating current air switch 30 disconnects automatically;
Direct current air switch 50, the direct current air switch 50 are connected on the straight of solar panel 20 and combining inverter 10 Input side is flowed, and the direct current air switch 50 is provided with the auxiliary closure motor 40 that can drive its time-delay closing;In the present embodiment Direct current air switch 50 has two groups, it can also be provided that multigroup;In addition, between solar panel 20 and direct current air switch Also have additional Double safety device F;Above-mentioned auxiliary closes motor 40 and realized with the butted part of controller 60 by motor-drive circuit, such as Diagram.
Controller 60, the controller 60 carry the AC power supplies 70 that civil power is obtained from self-resetting type over-and under-voltage protector side, should AC power supplies 70 is that controller 60 and auxiliary closure motor 40 are powered, and controller 60 has the remote of wireless communication module and back-stage management The communication connection of process control terminal 80, so that the controlled in wireless of remote control terminal 80 aids in closure motor 40 to start and then completes exchange The divide-shut brake of air switch 30 or direct current air switch 50 controls.
As the instantiation of the technical program, wireless communication module is using the GSM address cards of mobile data on flows, is somebody's turn to do The communication data transmission that GSM address cards are used between controller 60 and remote control terminal 80, controller 60 have monitoring power network Whether normally, the control of alternating-current switch state, alternating-current switch, the control of dc switch state, dc switch and temperature-humidity monitoring etc. Function and data acquisition, using GSM address cards by long-range control of the data feedback monitored to background monitoring center or user side Terminal processed(Such as mobile phone).It should be noted that GSM address cards are only preferable to carry out as the wireless communication module of the technical program Example, other known wireless communication module are equally applicable to the utility model.
Further, 60 such controller of controller, as long as the local can for having mobile phone signal uses, using area scope More extensively, using GPRS flow mechanicss of communication, can mobile phone remote control APP real-time status feedback configuration simple operations easy to get started, There are controller various modes may be selected, can more people control, a key control, memory function is not optional for power-fail memory function power-off, private Passport account, it is ensured that remote operation is safe and reliable;Scene carries LED display lamps(Or display), it is respectively used to display switch shape State and signal designation, for example shutdown is represented when LED is gone out, and LED signal indicator lamp dodges and then judges to enter GSM mobile networks for 2 seconds one Network.
