The invention discloses an NB-IOT remote switching-on and switching-off control system, which comprises a voltage reduction module, a power supply circuit, an NB-IOT transmitting circuit, a remote control module, an NB-IOT receiving circuit, a relay control circuit, a photoelectric isolation switch circuit, a main chip circuit, a first relay coil and a second relay coil, wherein the voltage reduction module is connected with the NB-IOT receiving circuit and the relay control circuit through the power supply circuit, the relay control circuit and the NB-IOT receiving circuit are both connected to the main chip circuit, the photoelectric isolation switch circuit is connected with the main chip circuit, and the remote control module is wirelessly connected to the NB-IOT receiving circuit through the NB-IOT transmitting circuit. The NB-IOT remote switching-on and switching-off control system has the beneficial effects that the remote control module sends an switching-on or switching-off signal to the NB-IOT receiving circuit through the NB-IOT transmitting circuit, the NB-IOT receiving circuit controls the switching-on or switching-off circuit through a main chip and the relay control circuit according to the switching-on or switching-off signal, the remote control effect is achieved, the switching-on or switching-off circuit can be controlled on site, and the combination of local field control and remote control is realized.
Description
technical field [0001] The invention relates to the technical field of opening and closing control, in particular to an NB-IOT remote opening and closing control system. Background technique [0002] Such as figure 1 Shown is the opening and closing control circuit diagram of the prior art, including the start button SB1, stop button SB2, contactor coil KM and contactor auxiliary contact KM1, the start button SB1 is connected to the contactor coil KM through the stop button SB2, and the contactor The auxiliary contact KM1 is connected in parallel with the start button SB1. When the start button SB1 is lowered, the contactor pulls in, and the contactor auxiliary contact KM1 also pulls in. When the start button is released, the contactor auxiliary contact KM1 still pulls in, and the contactor coil KM remains on. When the stop button SB2 is released, the contactor auxiliary contact KM1 is released, the start button SB1 and the contactor auxiliary contact KM1 are both disconne...
