Description
Technical field
The present invention relates to the dynamo-electric road of key switch, specifically refer to system physical key multiplexing design circuit.
Background technology
The dynamo-electric road of common key switch, be can start shooting immediately by after starting key equipment, after secondary button, equipment shuts down immediately.And in some electronic product equipments, particularly portable equipment, as mobile phone etc., all the long key switch machine control circuit adopted: the switching on and shutting down of such as mobile phone, when the switching on and shutting down process of general mobile phone is for start, need the action by the sufficiently long switch switch of switch switch, as long as the time of pressing key is less than the time of mobile phone in advance, equipment can not produce any switching on and shutting down operation (namely long key switch machine just produces boot action by equipment after switching on and shutting down time long enough exactly).The benefit done like this is the pressing unintentionally preventing the electronic equipment switches such as many such as mobile phones, causes start or the shutdown action of the electronic equipment execution error be placed in bag or in pocket.For the handheld electric products of such as mobile phone and so on, necessary when having a circuit of such power on/off function and characteristic.Realization prevents false triggering long button extending switch machine function, and a kind of easy way utilizes discrete original paper to add that auxiliary circuit realizes as RC time delay, has principle simple, cheap, design is convenient, but its time delay accuracy is low, can only partly prevent false touch circuit, adopt special switching on and shutting down chip to realize, reliability is high, simplicity of design, but because it is professional, therefore price is more expensive, common market is not easily purchased, and amateur making or other application realize not easily.
Foregoing is in order that for the on/off circuit of hand trigger-type, and in many radio communications, in 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, without the need to Artificial Control, can solve human cost problem.But in many real-time control, the scheme of automatic switching can not as the object adopted.Based on the demand controlled in real time, therefore, we need a kind of can for the signal of RFID antenna signal after rectification, by this on/off circuit, can the switching on and shutting down signal of triggering system, thus reach the on/off circuit of the object of the wireless signal triggering system switching on and shutting down using RFID.
In production wireless terminal, before the production of its pcb board, need to design, debugging pcb board can be made after design, therefore switching circuit be needed for wireless terminal, but as the emergency parachute of system, therefore also need urgency signal call circuit.Therefore wireless system is needed to the button of a urgent call, and the normal switching on and shutting down of system should be waken up by wireless signal, but the system research and development debug phase in early stage, conveniently debug and operate, how the button of urgent call uses as switching on and shutting down button, thus makes to save a kind of method producing cost.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, cost is low, uses a switch key, as the switch of switching on and shutting down signal when can realize debugging early stage, can be used as the system physical key multiplexing design circuit of emergency signal switch during the later stage production and operation.
Implementation of the present invention is as follows: system physical key multiplexing design circuit, comprise the urgency signal input terminal of connecting successively, urgent resistance R24, switch resistance R8, also comprise connect successively switch signal input end, switch resistance R68, urgent resistance R69, urgency signal lead-out terminal, also comprise switch J11, described switch J11 is connected with urgent resistance R24, switch resistance R8, switch resistance R68, urgent resistance R69 simultaneously.
Described switch J11 comprises four switch pin and is respectively: urgency signal input pin 1, switching signal output pin 2, switching signal input pin 3, urgency signal output pin 4; Described urgency signal input pin 1 is connected away from one end of urgency signal input terminal with urgent resistance R24; Described switching signal output pin 2 is connected near one end of urgent resistance R24 with switch resistance R8; One end that described switching signal input pin 3 and switch resistance R68 keep away OFF signal input terminal is connected; Described urgency signal output pin 4 is connected away from one end of urgency signal lead-out terminal with urgent resistance R69.
Described urgent resistance R24 and switch resistance R8 is 0R resistance.
Described switch resistance R68 and urgent resistance R69 is 0R resistance.
Link position between described switch signal input end and switch resistance R68 leads to a lead-in wire, and described wire locations is provided with test point TP_ON/OFF.
Based on foregoing, operation principle of the present invention is: need on the switch J11 basis of a urgency signal calling in system, and the normal switching on and shutting down of system should be waken up by wireless signal, but the system research and development debug phase in early stage, conveniently debug and operate, this switch J11 uses as switching on and shutting down button, after treating that the debugging of whole switching on and shutting down flow process is smooth and easy, then is that the switch J11 that urgent model is called out carries out debugging urgent call by its wire jumper.
System possesses an external physical switch J11, and this switch J11 uses as switching on and shutting down button when system debug in early stage, and on final volume production version, this switch J11 uses as push button for emergency call.These two kinds of functions control with one group of wire jumper respectively, can not use simultaneously.
Therefore: when switch J11 uses as switching on and shutting down button when system debug in early stage: switch signal input end, switch resistance R68, switch J11, switch resistance R8 line conduction, form on/off circuit, circulation switching on and shutting down signal, the circuit that can control between limber up period that cut-offs of switch J11 cut-offs, and forms a physical button switch; When switch J11 uses as push button for emergency call, after wire jumper process, urgency signal input terminal, urgent resistance R24, urgent resistance R69, urgency signal lead-out terminal line conduction, form urgency signal circuit, circulation urgency signal, the circuit cut-offfing urgency signal of switch J11 cut-offs, and forms a physical button switch.
The invention has the advantages that: facilitate system debug, when PCB need not be redesigned, taken into account the convenience of research and development debugging.
