Description
(pass) machine method and device thereof are opened in the remote control that the present invention relates to television set, exactly are to repeat to connect and cut off the method and the device thereof of drone version television set power supply about a kind of by remote control, and this device is for being independent of the corollary apparatus of television set.
Known drone version television set is provided with " awaiting orders " state (Stand By) usually, its purpose is to utilize the remote control means that it is repeated out (pass) machine, but not belonging to, its meaning do not cut off opening under the power supply notion (pass) machine fully, otherwise in case after the shutdown, television set can not be started shooting once more by remote control command.Accessory power supply only when television set is awaited orders, some digital circuit and remote control receive the relevant charging operation under low-power consumption that partly waits, and the right any damage that may cause of awaiting orders for a long time also is the damage of television set itself undoubtedly.So user, the user who especially with the family is the unit for various considerations, often adopt manual mode shutdown (cutting off the electricity supply fully) to replace " awaiting orders " state, therefore also just lost the possible condition of remote-controlled start-up in this case.No matter " await orders " state or remote-controlled start-up function under the meaning of cutting off the electricity supply fully is set in addition of television set setting all is not that (pass) machine function is opened in the remote control under the complete meaning.Generally adopt the TV remote-control of " awaiting orders " method to open with regard to (pass) machine method with regard to it, its weak point itself is to be difficult to be overcome at the drone version television set.
(pass) machine is opened in the known remote control that is independent of television set, and its mode adopts single signal to carry out remote control usually, and device is promptly carried out (pass) machine of opening in accordance with regulations in proper order after receiving this signal.The another kind of normal mode that adopts is to differentiate the instruction of (pass) machine with the length of sending the remote signal time.But above-mentioned various opening (pass) machine mode all can not be utilized the former remote control signal generator of drone version television set.Reason is that the remote control command of television set often reaches tens of kinds, and every kind of instruction all has its specific function, the time length of sending remote signal during use is again at random, so adopt the former remote control signal generator of drone version TV to control the confusion that will cause various functions and drive (pass) machine.Because control signal is simple, its antijamming capability is lower than the code identification circuit, in case no matter false triggering is the function that device or television set self all do not possess automatic shutdown, gives rise to trouble.If will discern special opening (pass) machine command code, could respond signal behind identification that must be by special setting and the decoding circuit, this often makes circuit complexity and cost higher, its coding definition of the remote control command sign indicating number of each producer is different still more, and the device that therefore possesses this function does not possess versatility.
Open (pass) machine method and device thereof by above-mentioned known remote control, for the drone version television set, the one, can not realize cutting off fully and open (pass) machine function under the television set power supply meaning, again if just have to use two remote control signal generators, perhaps cost is higher and do not possess versatility.Therefore no matter from actual needs, easy to operate, installation cost, protection and prolong aspects such as television life-span and user's psychology and opinion is inappropriate all.
The objective of the invention is to repeat to connect and cut off the method and the device thereof of drone version television set power supply about remote control.
One of purpose of the present invention is about repeating to connect and cut off the method for this television set power supply with the former remote control signal generator remote control of drone version television set.
One of purpose of the present invention provides a kind of drone version television set that is independent of, and the universal remote control that can respond its former remote control signal generator remote control command opens (pass) machine, to satisfy needs of society.
The method that achieves the above object is: this method is the armed state that the armed state of drone version television set is converted into " (pass) machine is opened in remote control " on the outer current supply circuit of the machine of being arranged on, arbitrary command signal of sending to " (pass) machine is opened in remote control " by former remote control signal generator is as start-up command, thereby connects the television set power supply; The standby instruction of sending to the drone version television set is as shutdown command, when " (pass) machine is opened in remote control " detects television set and be ready in the television set current supply circuit after, promptly cuts off the television set power supply through time-delay again.
Usually remote control signal generator sends tens of kinds of command codes and finishes various specific functions with the control television set, but the common trait of various machine is a command code is to launch by CF signal, especially the extensive infrared remote control that adopts, its carrier frequency concentrates on about 40KHz, therefore can receive consciousness by the reception head with bandpass filtering link.So adopt and to send the method for arbitrary command code, promptly need only receive CF signal and no matter the sign indicating number type of instruction, just can carrying out starts shooting makes as start-up command to " (passs) machine is opened in remote control ".It is the bandpass filtering link of 30-60KHz that adjustable frequency is set, and can satisfy the needs of various machine, and versatility is very strong.Because start-up command is arbitrary instruction that generator is sent out, therefore only when power supply is cut off start-up command just effectively real, in case after starting shooting, the start-up command of various equivalences loses meaning automatically, so start back television set can carry out the normal remote control operation of various functions, function is without prejudice.
The drone version television set is provided with armed state, (comprise TV turn off the state of mains switch) " power consumption during the television set operate as normal of its power consumption when awaiting orders, difference on this power consumption meaning will be embodied on the television set current supply circuit, so can utilize this difference to judge whether television set requires shutdown.Setting await orders and the median (this value generally can satisfy various television set) of operating state television set power consumption meaning as discriminant value, when being ready in case television set receives standby instruction, the perception at once of (pass) machine is opened in the remote control that is in the current supply circuit, be equivalent to device and received shutdown command, cut off power supply.Therefore this with the mode of standby instruction as shutdown command, have the strongest universal.
Because shutdown command also is equivalent to start-up command from certain angle, so press when awaiting orders key, remote control is opened (pass) machine and is received start order and shutdown order simultaneously, may cause the instability of television set on open and closed.In order to overcome above-mentioned instability, and to touch accidentally in preventing to use and await orders key and cut off the electricity supply, also in order to keep the characteristics of the former armed state of television set, just taked to carry out the method for shutdown through the certain time-delay time after being received when shutdown makes.The armed state that has kept a period of time is brought operational bigger flexibility to the user, and having overcome start-up command is the contradiction of same instruction, has also greatly improved the antijamming capability of being opened the system of (pass) machine and television set formation by remote control simultaneously.After the general drone version TV energized, television set still is ready, so after power supply is cut off, the energized in case run into powerful interference (be equivalent to remote control switch machine receive start make) because television set is ready, opened (pass) machine and has been received to shut down and make so be equivalent to remote control again, after time-delay, cut off the electricity supply automatically again, therefore say that this method has the characteristics of automatic shutdown on this meaning, antijamming capability is strong.
The working procedure process of this method: (the setting remote control is opened (pass) machine and is ready, and TV set power is cut off).Press the arbitrary button (key of also can awaiting orders) on the former remote control signal generator, device receives start-up command, promptly connects TV set power, and this moment, television set was ready (indicator light is bright).If not launching working signal in delay time devotes oneself to work television set, power supply was cut off again after then time-delay finished, if promptly press the work button of remote control generator in delay time, television set is devoted oneself to work.After seeing that TV finishes, press the key of awaiting orders, television set enters armed state, cuts off the electricity supply automatically after delaying time.Therefore whole work or operating process, just many by primary key start remote control and open (pass) machine power connection, easy to operate.
The object of the present invention is achieved like this: the electrical schematic diagram of the one embodiment of the invention shown in showing is in conjunction with the accompanying drawings set forth.
This device ((pass) machine is opened in remote control) is serially connected between city's power supply (8) and the outer current supply circuit of drone version television set (19) (20) and is independent of television set, by the receiving circuit part (21) that receives head (2), front end circuit (3), bandwidth-limited circuit (4) formation is arranged; By the state control circuit part (22) that has control circuit (6), given circuit (10), comparison circuit (11), delay circuit (12), signaling conversion circuit (14) to constitute; And indicating circuit (7), drive circuit (16), power circuit (9), actuator (15) etc. are partly formed.Wherein state control circuit partly (22) to the reception input port of enabling signal (5) with receiving circuit partly the output port of (21) be connected, and the state control circuit partly same respectively indicating circuit of output (7), the drive circuit (16) of (22) is connected, and the output of drive circuit is connected with the actuator (15) between the current supply circuit (20) that is serially connected in city's power supply (8) and television set (19).Its characteristics are to be provided with its signal output part with the State Control state detection circuit (13) that is connected of an input port of (22) partly, to detect the current state of television set under the power consumption meaning between city's power supply (8) and drone version television set (19) current supply circuit (20).
When receiving head (2) and receive the CF signal (1) that remote control signal generator sends (being equivalent to arbitrary command code), toward front end circuit (3) processing and amplifying, and in the presence of bandwidth-limited circuit (4), send (or one a group) enabling signal (5) by receiving circuit part (21) to state control circuit part (22), state control circuit is partly promptly exported control signal (18), makes actuator (15) connect the television set power supply behind drive circuit (16).Therefore receiving circuit partly (21) be transported to state control circuit partly the enabling signal (5) of (22) be equivalent to start-up command, so it all is start-up command that this device receives head (2) external remote control signal that directly receive and that cause response by it, and can not carry out corresponding specific function according to the specific meanings of its instruction.This device is in case the start-up command that receives once more is owing to still carry out the start task after the start, so no practical significance thereby is an illegal command, promptly the start-up command that only this device receives under the cut state of television set power supply is only effective instruction.
The output signal that is arranged on the state detection circuit (13) on the current supply circuit (20) is delivered to state control circuit partly (22), pass through signaling conversion circuit (14) therein with after the signal transformation, in comparison circuit (11), compare with the set point of sending here by given circuit (10).Wherein set point is the charge value of setting according to television set work and the intermediateness of awaiting orders.When television set is in running order, comparison circuit (11) non-output signal, its meaning does not promptly allow shutdown, when television set is ready, current power consumption value is sent one " allowing off signal (17) " by the control circuit (6) of comparison circuit (11) in the state control circuit part after relatively in comparison circuit, be equivalent to this device and received " shutdown command " this moment, thereby control circuit (6) is received and is allowed promptly to start delay circuit (12) behind the off signal (17), and, cut off power supply by control circuit (6) output control signal (18) and by actuator through behind the delay time of setting.Therefore shutdown command is by being sent by the television set of remote control when transferring armed state to by television set.
The control signal of partly being sent to drive circuit (16) by state control circuit (18) is divided into (t1) and (t2) two sections in time: when this device receives effective start-up command and during energized, this moment, television set was if only rest on armed state and the state of not devoting oneself to work, then the control signal (18) of control circuit output is in (t2) time phase, and (t2) time for the treatment of finishes the back and carries out the shutdown task.The state if television set was devoted oneself to work before (t2) time finishes, control signal (18) changes (t1) time phase over to, and (t1) time is determined by the length of television set operating time.Therefore (t1) is the television set operating time, for awaiting orders time in stage or be called delay time, is power cutoff after (t2) finishes (t2).No matter be (t1) and (t2) time phase, only need (t2) time not finish (for set point) then (t1) and (t2) all can be by the external remote control signal with " start-up command " and " standby instruction " mutual conversion, applying flexible.
The present invention has overcome existing drone version television set deficiency in use, makes television set itself and power supply by on the remote control meaning and opinion, and the present invention makes television set become the Full remote controlled type by original semiremote handling.Because this device serial connection on current supply circuit, therefore can not cause any substantial change and destruction to television function and safety.Again because this device can respond the signal of the original signal generator of former remote control machine; so the operator only just can realize all distant control function operations of cutting off TV set power that comprises with original-pack signal generator; and in a single day television set is ready the trend that has just possessed automatic shutdown; the anti-dried ability of scratching by force, convenient again; yet having protected television set, is a kind of supporting device of drone version television set that aims at.
