Method for adjusting parameters of remote control model receiver and remote control model

Abstract

The invention discloses a method for adjusting parameters of a remote control model receiver and a remote control model. The remote control model receiver is provided with an adjustment state signal judging module and an adjustment parameter processing module. The method is implemented as follows: judging whether a signal emitted from a remote control unit and received by the receiver is a preset adjustment state entering signal or an adjustment state exiting signal by the adjustment state signal judging module; taking received subsequent signals as adjustment parameters and processing the subsequent signals by the adjustment parameter processing module if the signal is a preset adjustment state entering signal; and never receiving the subsequent signals any more by the adjustment parameter processing module if the signal is a preset adjustment state exiting signal. The method for adjusting the parameters of the remote control model receiver provided by the invention is in no need of a trimmer potentiometer, input / output port wires and analog / digital conversion, and the model shell can realize parameter adjustment for the receiver without tapping.

Description

technical field [0001] The invention relates to the field of miniature models, in particular to a parameter adjustment method applied in the field of miniature remote control models and a remote control model. Background technique [0002] For remote control models, such as the receiver of the remote control helicopter model, relevant parameters need to be set according to the different characteristics of each model, so as to ensure the normal flight of each remote control helicopter model. In the past, the setting of these parameters was realized by the trimmer potentiometer on the electronic board of the remote control model receiver. If the remote control model needs to set three parameters, three trimmer potentiometers should be arranged on the electronic board; Figure 1 shows The schematic diagram of the circuit structure of a typical remote control model helicopter receiver, as shown in the figure, three potentiometers are set on the receiver, namely, the sensitivity a...

Problems solved by technology

[0009] It is not difficult to see that the parameter adjustment of the remote control model receiver through the manual adjustment of the potentiometer will not only increase the number of electronic components, but also increase the Arranging these components on the electronic circuit board of the receiver will not only increase the cost, weight and area of ​​the electronic circuit board, but also the adjustment process of the trimmer potentiometer on the electronic circuit board of the receiver is very troublesome, especially after the remote control model is fully assembled , it is necessary to pre-open several adjustment holes in the corresponding position of the remote control model case, and the screwdriver used for adjustment should go deep into the hole, and adjust by fumbling for the position of the trimmer potentiometer. This operation is quite troublesome, and it is easy to damage the trimmer potentiometer.

The trimmer potentiometer itself is also a kind of electronic component that is prone to failure. It is prone to deviation of parameters due to poor contact, thus causing the failure of the remote control model to work normally, and even the complete failure of the trimmer potentiometer, which makes the electronic circuit board scrap

On the other hand, in the data processing process of the remote control model receiver, it is first necessary to perform A / D conversion on the adjustment voltage of the trimmer potentiometer, and then send the converted data to the corresponding register for storage, and then transfer these To read out the stored data, this design not only needs to use several ports, but also requires A / D conversion for each operation, which requires more port resources and more computing time.
