Description
Technical field
The present invention relates to on/off circuit, specifically refer to adopt the on/off circuit of reset chip.
Background technology
The dynamo-electric road of common key switch is by can start shooting immediately after starting key equipment, and after inferior button, equipment shuts down immediately.And in some electronic product equipments, portable equipment particularly, as mobile phone etc., all the long key switch machine control circuit that adopts: for example switching on and shutting down of mobile phone, when the switching on and shutting down process of general mobile phone is start, need the action press the sufficiently long switch switch of switch switch, if the time of pressing key less than time of mobile phone in advance, equipment can not produce any switching on and shutting down and operate (namely long key switch machine just produces boot action by equipment after switching on and shutting down time long enough exactly).The benefit of doing like this be prevent many such as the electronic equipment switches such as mobile phone be not intended to press, cause being placed on start or the shutdown action of the electronic equipment execution error in bag or in pocket.For the handheld electric products such as mobile phone, necessary when the circuit of such power on/off function and characteristic is arranged.Realization prevents the long button extending switch of false triggering machine function, and a kind of easy way is to utilize discrete original paper such as RC time-delay to add the auxiliary circuit realization, has principle simple, cheap, design is convenient, but its time-delay accuracy is low, can only partly prevent the false touch circuit, adopt special-purpose switching on and shutting down chip to realize, reliability is high, simplicity of design, but professional because of it, therefore price is more expensive, common market is difficult for buying, and amateur making or other application realize being difficult for.
Foregoing is in order that for the on/off circuit of hand trigger-type, and in many radio communications, in the controlled in wireless field, the majority that on/off circuit usually adopts is the design of automatic time switch machine.The dynamo-electric road of this automatic time switch need not Artificial Control, can solve the human cost problem.But control in real time many, the scheme of automatic switching can not be as the object that adopts.Demand based on real-time control, therefore, we need a kind of can be for the signal of RFID aerial signal after rectification, by this on/off circuit, switching on and shutting down signal that can triggering system, thus reach the on/off circuit of the purpose of the wireless signal triggering system switching on and shutting down of using RFID.
Summary of the invention
The object of the present invention is to provide a kind of simple in structurely, cost is low, can guarantee the on/off circuit of the employing reset chip that the invalid signals in reference time delay is all filtered out by effective mistake.
Implementation of the present invention is as follows: adopt the on/off circuit of reset chip, mainly be made of reset chip circuits for triggering and the rectified signal input port that all is connected with the reset chip circuits for triggering, switch owner process chip, VRTC circuit.
Described reset chip circuits for triggering comprise reset chip D1, capacitor C 1, resistance R 1; Reset chip D1 comprises VSEN pin, VIN pin, VOUT pin, CD pin, GND pin; Described VSEN pin is connected with the rectified signal input port, and described CD pin is connected with capacitor C 1, resistance R 1 successively, and an end ground connection of described resistance R 1 close capacitor C 1, and resistance R 1 is connected with the VSEN pin away from an end of capacitor C 1; Described VIN pin is connected with the VRTC circuit; The VOUT pin is connected with switch owner process chip; Described GND pin ground connection.
Described VOUT pin is connected with the ON/OFF pin of main process chip.
The model of described reset chip D1 is XC6118, and its reset threshold is 1.8V.
The resistance of described resistance R 1 is: 100K ± 100K*5%.
The capacitance of described capacitor C 1 is: 100nF ± 100nF * 10%.
The signal input of above-mentioned rectified signal input port after as the antenna rectification is uploaded to the VSEN pin with the signal after the antenna rectification.
The time of delay of the adjustable reset chip D1 of above-mentioned capacitor C 1.
Above-mentioned reset chip D1 receives signal after the antenna rectification and reaches after threshold values after the regular hour, its VIN pin, the conducting of VOUT pin, thus make the switching on and shutting down signal be triggered.And the switching on and shutting down signal is uploaded to switch owner process chip by the VOUT pin.
Based on the foregoing circuit framework, signal controlling flow process of the present invention is: use a reset chip D1 to be the basis, build the on/off circuit of system.Reset chip D1 is in the state that detects input signal all the time, when the input signal of rectified signal input port reaches threshold voltage 1.8V, reset chip D1 can export a signal specific as output signal, this signal is determined by the power supply of reset chip D1, is the switching on and shutting down power supply signal in this design.And the signal of output is connected to the ON/OFF pin of switch owner process chip.That is to say when reset chip D1 is triggered, the switching on and shutting down power supply signal is to the ON/OFF pin output of switch owner process chip, the switching on and shutting down flow process of trigger switch owner process chip.Reset chip D1 has the input signal delay feature simultaneously, after namely inputting a signal maintenance certain hour, just can trigger reset chip D1 output signal.
Can use equally wireless signal control switch machine except the on/off circuit of building with triode or metal-oxide-semiconductor in the present invention, use the reset chip D1 threshold voltage of control switch machine comparatively accurately, because its threshold voltage arranges when dispatching from the factory, and precision is very little, compare triode and metal-oxide-semiconductor, the threshold voltage error of its triggering is less.And because the exclusive time-delay Trigger Function of reset chip D1 can guarantee that the invalid signals in reference time delay is all filtered out by effective mistake, thereby played the effect that shielding is disturbed.
The invention has the advantages that: 1, simple in structure; 2, possesses the extension Trigger Function; 3, can guarantee that the invalid signals in reference time delay is all filtered out by effective mistake, thereby play the effect that shielding is disturbed.4, production cost is low.
