Abstract
The present invention relates to a method for correctly identifying and blanketing noise interference fault in chips of remote control toys. Through fault blanketing technology, when receiving detectable fault signals, the chip of a remote control toy distinguishes whether an emitter stops emission or the noise interference causes error codes, and then different methods are adopted to carry out processing; if the fault signal is in the former state, the output is kept for some time and then is shut off to prevent keys shaking; if the fault signal is in the latter state, the previous output is kept.
Description
Technical field
The present invention relates to a kind of method of in the remote-control toy chip, correctly discerning and cover the noise jamming mistake.
Background technology
Remote-control toy is in remote control process, because the influence of surrounding environment or distance, recipient has certain probability to receive wrong signal, present remote-control toy chip is after receiving these rub-out signals, if detected signal all is rub-out signal (no matter being that what reason causes) in one period set time, then the output zero clearing.Like this, the remote-control toy chip can not distinguish that the wrong reason that takes place is that reflector stops to have launched or because noise jamming and error code also can't divide other processing to these situations when receiving wrong signal.
Summary of the invention
In order to overcome the remote-control toy chip can not be differentiated the origin cause of formation of the rub-out signal that is received and can't adopt the different disposal method to the rub-out signal of different origins in remote control process drawback, the present invention covers wrong technology by use, make chip when receiving detectable rub-out signal, differentiating earlier is that reflector stops to launch or the error code that noise jamming causes, adopt diverse ways to handle then, just keep output a period of time just to close output (preventing key jitter) to the former, the latter is then kept previous output.
For the remote-control toy chip, all need frame synchronization, promptly each frame data all can have the starting point that a stature signal comes marking signal, and the present invention just judges with the correctness of this stature signal whether reflector transmits.If in one period regular time, do not find a correct signal, then can regard as reflector and not transmit; If find a correct signal, and data-signal has detectable mistake, then can regard as mistake is that noise jamming causes.The remote-control toy chip is handled on the basis of the rub-out signal that is received being made above-mentioned different identifications accordingly, that is: do not transmit as being identified as reflector, and chip stops output after through one period regular time; As to be identified as be the rub-out signal that noise jamming causes, and chip keeps previous output.
Advantage of the present invention has: the origin cause of formation that 1, can differentiate rub-out signal; 2, can adopt different processing methods to the rub-out signal of different origins.
The present invention can make the remote-control toy chip significantly promote not jitter distance of remote control under the situation that does not reduce reaction speed.
Description of drawings
Fig. 1 is the flow chart of one embodiment of the invention.Wherein, A represents to receive coherent signal; B represents that the signal that A is accepted carries out an input; C represents to find to have a signal according to the detection of B; D represents because of existing the signal among the C to assert that rub-out signal is that noise jamming causes; E represents to keep previous output according to the identification of D; F represents that a signal is not found in preliminary survey through B; T represents the input that F continued to carry out one period set time t second; G represents to find a signal after the elapsed time t detection of second and stops output.
Embodiment
As Fig. 1, the remote-controlled toy vehicle that is advancing, receive the signal (A) that allows dolly advance of remote control transmitter emission suddenly, the remote-control toy chip carries out an input (B) to the signal that allows dolly advance that is received, a header signal is correct if any detecting, the signal of error in data, dolly will move on (C, D, E); Continue t as the remote-control toy chip and do not detect signal to the end second, dolly halt (G); There is not t to detect in the time in second that a stature signal is correct, the signal of error in data as the remote-control toy chip, dolly move on (C, D, E).
Claims (2)
1, correctly discern and cover the method for noise jamming mistake in the remote-control toy chip, it may further comprise the steps:
Chip keeps a continual search signal;
After searching to the end signal, illustrate that a signal of this packet is correct, then further whether the data-signal of detection head signal back is wrong;
If it is wrong to detect subsequent data signal, assert then and cause that chip keeps current drive signal output by noise jamming.
2, the method for in the remote-control toy chip, correctly discerning and cover the noise jamming mistake according to claim 1, it is characterized in that: in a duration section, do not search for signal to the end as fruit chip, assert that then reflector does not transmit, chip stops output after through one period regular time.
