Embodiment
Technical scheme provided by the invention is: utilize the control chip control infrarede emitting diode with microprocessor MCU function of telepilot inside periodically to launch infrared pulse, the remote-control electrical equipment supporting with telepilot receives infrared pulse, if someone or thing block infrared pulse, the remote-control electrical equipment supporting with telepilot can't receive infrared pulse, when not receiving infrared pulse with the supporting remote-control electrical equipment of telepilot in cycle regular hour, its inner control chip will trigger warning; Periodically send intermittent phase of infrared pulse at telepilot, the MCU in the telepilot is in battery saving mode with automatic remote controllers, also saves the telepilot electric energy.
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Be that example describes with televisor and supporting telepilot thereof in the embodiment of the invention, also can realize technical scheme provided by the invention on other household electrical appliance, its principle is similar.
Fig. 1 is the telepilot theory diagram of inventive embodiments, comprises keyboard matrix, pulse encoder, MCU and infrared emission head composition.
Different with existing TV remote controller is, increased " antitheft startup " button in the embodiment of the invention telepilot keyboard matrix, this button is used for starting the anti-theft alarm function of telepilot, during specific implementation, also can multiplexing telepilot on existing certain button or key combination.
Press " antitheft startup " button of telepilot the user after, telepilot MCU sends a specific remote control mode.This remote control mode form is with other buttons, the code value that just is different from other buttons, be convenient to receiving end identification, to show that telepilot begins to enter the state of regular transmission infrared pulse, next control chip MCU begins periodically to produce control wave, drives infrarede emitting diode and periodically sends infrared pulse signal.Certainly, when specific implementation, also can not send above-mentioned specific remote control mode, directly periodically produce infrared pulse signal by telepilot MCU.After infrarede emitting diode sends an infrared pulse signal, in excess time in this cycle, the MCU remote controllers enters the energy saving standby state and picks up counting, after this timing time arrives setting value (one-period), waken system sends a pulse signal once more.
Above-mentioned setting value is the time interval of periodic transmission infrared pulse, and its numerical values recited can be determined according to actual needs.If there is not new button to press, then telepilot is just periodically launched infrared pulse always.When MCU detects after any button presses once more, system's dwelling period transmission infrared pulse signal, and send the remote control mode of this button.
The described system of the embodiment of the invention as shown in Figure 2, comprise telepilot and televisor, the circuit structure of telepilot and principle of work are as mentioned above, TV set terminal has increased the burglar alarm module on existing televisor basis, link to each other with TV MCU, when not receiving infrared pulse in the cycle that televisor is being set, TV MCU starts the burglar alarm module, the burglar alarm module starts warning function, as sending chimes of doom by hummer or alerting signal being transferred to the Property Management of residence system.
At the televisor receiving end, the infrared pulse that telepilot produces is exported the middle fracture that an impulse level signal is given MCU after infrared receiving terminal receives, and makes MCU produce and interrupts.
Televisor recognizes " antitheft startup " button in reception after, beginning regularly detects whether produce the remote control interruption, interrupts taking place as there is remote control in the time of setting, and illustrates that the remote control pulse is interdicted, and MCU produces alerting signal.
As shown in Figure 3, the flow process of telepilot work mainly comprises the steps:
(1) user presses " burglar alarm " function button, or presses some combination button, starts the telepilot anti-theft feature.
(2) telepilot sends a specific remote control mode, and televisor enters anti-theft state after receiving this remote control mode.
(3) telepilot sends an infrared pulse signal at first timing cycle.
(4) if televisor receives telepilot emission infrared pulse signal, then change step (5), if the people is arranged through between telepilot and the televisor this moment, infrared pulse signal is interdicted, and when televisor does not receive infrared pulse signal, changes step (7).
(5) after infrared pulse signal sent, the MCU remote controllers was in the energy saving standby state, and timer picks up counting.
(6) timing cycle of She Dinging expires, and telepilot sends infrared pulse signal once more, changes step (4).
(7) TV MCU triggers anti-theft alarm function.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
