Below in conjunction with the accompanying drawings the specific embodiment of the application is described in more detail.
As shown in figure 1, the television system of the control AC switching on and shutting down of the application proposition, including TV and remote control, TV 11
Power supply circuit board 111 and AC switching on and shutting down module 112 are installed, power supply circuit board 111 includes exchange electrical input AC_In and electricity
Power-switching circuit Cov;AC switching on and shutting down module 112 includes infrared receiving terminal P and control circuit U, and the outfan of infrared receiving terminal P connects
One signal input part Pin1 of connection control circuit U;On power supply circuit board 111, AC_In and Power convert electricity are input in alternating current
Relay R is installed between the Cov of road;The first control output end Pout1 connection relay R of control circuit U, for triggering relay
Device is opened or closed.
Remote control 12 includes AC on & off switches, the AC on & off switches can be a button, or separate two by
Key, can be separately provided, it is also possible to and other button multiplexings.In diagram, AC on & off switches 121 are for AC switching on and shutting down modules
112 send ac dump remote signal or exchange start remote signal.
Specifically, when user wants ac dump, ac dump remote signal is sent using remote controller operation AC on & off switches,
Infrared receiving terminal P receives the ac dump remote signal so that control circuit U is based on ac dump remote signal from the first control
Outfan Pout1 output trigger control relays disconnect, and realize the AC shutdown of TV;When user will exchange start, make
Exchange start remote signal is sent with remote controller operation AC on & off switches, infrared receiving terminal P receives exchange start remote signal, makes
Obtain control circuit U to close from the first control output end Pout1 outputs trigger control relay based on exchange start remote signal
Close, realize the AC starts of TV.
It is above-mentioned to understand, in the television system of the control AC switching on and shutting down that the application is proposed, AC switches are provided with a remote control
Switch, user only need the AC in remote controller that the ac dump of TV is realized by switching switch;And in television, increase has
AC switching on and shutting down modules, the AC switching on and shutting down modules include reception remote control and send ac dump remote signal and exchange start remote control
The infrared receiving terminal of signal, and a control circuit is included, can for example realize the singlechip chip of simple control or have
Output control signal is produced after receives input control signal as the on-off circuit etc. of trigger;In the friendship of power supply circuit board
Between stream electrical input and power-switching circuit, a relay is connected with, the relay can be in the triggering for receiving control circuit
Disconnect after signal or close;After user sends ac dump remote signal using remote control, infrared receiving terminal receives the letter
Number and be sent to control circuit, control circuit sends trigger to relay based on this signal so that relay disconnects, so as to
Ac dump is realized in switching exchange input;And after user sends exchange start remote signal using remote control, infrared receiving terminal
The signal is received, and sends the signal to control circuit, control circuit sends trigger to relay based on this signal,
So that relay closure, so as to realize exchanging the path of input and power-switching circuit so that power-switching circuit exports TV
Running voltage, it is achieved thereby that exchange start.Compared to the mode that must operate TV in prior art to alternating-current switch machine,
The mode that the application is proposed causes user stand up to go to, and only needs operation
Remote control is capable of achieving the alternating-current switch machine of TV, has also prevented stand-by power consumption, solve while Consumer's Experience is improve
Existing TV needs to be manually operated AC switches to prevent the technical problem of standby energy consumption.
To ensure after TV ac dump, AC switching on and shutting down modules remain in that mode of operation, enabling receive remote control
The exchange start remote signal that device sends, and based on exchange start remote signal control TV exchange start, in the application, AC is opened
The power supply of shutdown module is realized that by external connection battery specifically, the feeder ear of the feeder ear and relay of AC switching on and shutting down modules connects
The positive pole output of external supplying cell.
Preferably, in order to save battery power consumption, in television startup state, it is possible to use TV power supply is AC switching on and shutting down moulds
Block is powered, and after TV ac dump state, uses battery instead and power.Specifically, as shown in Fig. 2 can in AC switching on and shutting down modules
There is power supply switch circuit Pch to increase;Power supply switch circuit Pch is connected to the positive pole output of battery B and power-switching circuit is defeated
Between the 5V voltage outputs for going out, the feeder ear of the feeder ear and the relay of 5V voltage outputs connection AC switch modules;The electricity
Source switching circuit switches 5V voltage outputs after being used for electricity on TV be that AC switching on and shutting down module and relay are powered, in TV power down

So that first switch pipe Q1 conductings, and then second switch pipe Q2 conductings are caused, realize that by battery be control circuit U, infrared receiver
Head P and relay R powers, now, the 5V voltage outputs power down of power-switching circuit.
After as user, in the case of TV AC dump, remote controller sends exchange start remote signal, infrared receiver
The ac dump remote signal of reception is sent to control circuit U by head P, and control circuit U is exported from the first control output end Pout1
Trigger trigger relay R is closed, and realizes the upper electricity of exchange, when the power-switching circuit of power supply circuit board has 5V voltage outputs
Afterwards, the second control output end Pout2 outputs low level so that Q1 and Q2 end, is control circuit U, red by 5V voltage outputs
Outer reception head P and relay R powers, and powers without the need for battery, so the power consumption very little of battery, can extend battery and use the longevity
Life.
The preferred normally opened relay of relay;This is because, in the case where not powering to relay, the path of relay is
Disconnect, when powering to relay and have trigger, the path of relay is closure.When the upper electricity of exchange, TV is used
5V voltage outputs are powered to relay, control circuit output trigger, armature adhesive inside relay;When AC dump,
Relay is to disconnect, and is powered without the need for battery, so power consumption very little.
