Description
Technical field
The present invention relates to switching circuit, be specifically related to power on-off control circuit.
Background technology
UART communication is a kind of transport communication of serial data bus, is that the parallel data that will receive converts serial data to and transmits, and is mainly used in asynchronous communication.This bus two-way communication can realize full duplex transmission and reception.In embedded design, UART communicates by letter with auxiliary equipment in order to main frame, as communicating by letter and communicating by letter with PC between automobile audio and the external AP.At communication technical field, it is multiplexing to use charging port through regular meeting, interferes with each other for avoiding the signal between the unlike signal in UART communication and switch control because charging port is multiplexing, can use wireless signal that charge power supply is carried out switch control.We know that high voltage refers to the voltage that is higher than 250V, and the safe voltage of human body is 36V, safe current be 10mA once, the safety that overtension can harmful to human.But for actual needs uses high voltage through regular meeting, and also can't use the wireless signal of low voltage in the prior art in the circuit, the charge power supply switch of control high voltage.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and power on-off control circuit is provided, and has realized using the requirement of charge power supply switch of the wireless signal control high voltage of low voltage.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: power on-off control circuit, comprise wireless control signal, triode T1, triode T2, resistance R 1, resistance R 2, resistance R 3, resistance R 4, resistance R 5 and charge power supply, described wireless control signal, resistance R 1, triode T1, triode T2, resistance R 3, resistance R 4 and charge power supply are connected successively, resistance R 4 wherein is connected on the collector electrode D of triode T2, and the collector electrode C of triode T1 is connected with the basis set of triode T2; Described triode T2, resistance R 3 and resistance R 4 are all in parallel with resistance R 3, input charge switch control signal between resistance R 3 and resistance R 4; Described resistance R 2 is in parallel with triode T1.
Further, the equal ground connection of emitter E of described resistance R 2 and triode T1.
Further, the emitter E ground connection of described triode T2.
Further, an end of described resistance R 1 and resistance R 2 all is connected with the basis set B of triode T1.
Further, described triode T1 and triode T2 are the NPN pipe.
Further, described resistance R 2 is 75 kilo-ohms.
Compared with prior art, the invention has the beneficial effects as follows: in the present invention, the control of charge power supply switch only needs a high level that is not less than charge power supply voltage, directly uses wireless control signal that the charge power supply switch is controlled, and the voltage of wireless signal is not enough.This design has successfully realized the control of wireless signal to the charge power supply switch by two NPN triode T1 and T2 conversion.And conversion speed is fast, and action is not accurately almost delayed time.
