Description

Technical Field

[0001] The present invention belongs to the technical field of wireless control, and in particular relates to a RF receiving system and a control method based on the RF receiving system. Background Art

[0002] In the field of wireless or radio frequency (RF) control technology, RF control systems are usually used to control controlled models such as remote control cars, aircraft models, and drones, so that the controlled models can perform actions that meet the expectations of users or operators, such as turning, moving forward, accelerating, etc. Specifically, by controlling the model components on the controlled model to perform corresponding actions, the RF receiving system is the key link between the RF control system and the controlled device. It receives the control instructions sent by the RF receiving system to control the model components, that is, the RF control system sends control instructions to the RF receiving system, and then the RF receiving system parses and processes the control instructions and outputs them to the controlled devices corresponding to each model component to control the model components, thereby realizing the control of the controlled model. In specific tasks or certain scenarios, it is necessary to coordinate and control multiple model components, or when controlling a model component, it is necessary to refer to the status of other model components. For example, when the remote control car model slows down, it is necessary to control the motor and the lights at the same time, and when performing a formation aircraft performance, it is necessary to control the lights, motors, and servos at the same time.

[0003] At present, when the model components are coordinated and controlled, the real-time status of each model component is judged by human judgment or RF control system, and control instructions are sent to the controlled device that controls the model component according to the real-time status of each model component to coordinate and control the model components. However, there are many model components on a controlled model and many control parameters involved in each model component. If human judgment is used, it is easy to cause the coordinated control accuracy of the model components to be low. If it is processed by the RF control system, the real-time status of multiple model components needs to be transmitted back to the RF control system through the RF receiving system for fusion processing, but the model components are not directly interoperable, which will lead to increased control delay and increased wireless link burden. Although there are also integrated machines with RF receiving systems and model components, the model components in this integrated machine are independent of each other and cannot realize data communication, resulting in the inability to coordinate work between the model components, and the coordinated control accuracy of the model components is low. Therefore, how to improve the coordinated control accuracy of each model component under the premise of ensuring that the control delay does not increase has become a technical problem that needs to be solved in the field of remote control technology.

[0056] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0057] Please refer to Figure 1 In the field of RF control technology, especially in the field of RF controlled vehicles, the controlled models basically have model components such as motors, lights, and servos. We control the model components (motor, light, servo) by connecting the controlled devices such as the electric control unit (control motor), light group (control the on and off of the lights), and servo module (control the direction of travel) to the RF receiving system of the controlled model. If the RF control system is used to handle it, the real-time status of multiple model components needs to be transmitted back to the RF control system through the RF receiving system for fusion processing, but the various model components are not directly interoperable, which will increase the control delay and increase the burden on the wireless link.

[0058] First, the control instructions of the electric tilt unit for controlling the motor need to be sent from the RF control system to the RF receiving system, and then from the RF receiving system to the electric tilt unit. For different setting requirements, additional tools such as parameter adjustment card devices are required to adjust the parameters. When implementing feedback control for the real-time motor data of the electric tilt unit, the real-time data also needs to be transmitted back to the RF control system for processing through a standard protocol, which will increase the control delay.

[0059] Secondly, for the control of the model lights, a large part of the control signal of the light group is used as the model status indicator light. Generally speaking, feedback signal control can be used. However, since other controlled devices of the model are all transmitted back to the RF control system for processing through the RF receiving system, they are not directly interoperable. To achieve feedback control, the model parameters need to be transmitted back to the transmitter for fusion, and then a new control signal is sent to achieve feedback control. This increases the control delay and the data burden on the wireless link.

[0060] In addition, there are many steering servo controls on the model, and it is hoped that they can be associated with the status of the engine. The existing control association can only be achieved through the preset mixing control of the RF control system, which is not accurate in some cases. For example, high-speed steering and low-speed steering servo control have different requirements, but relying solely on the throttle value cannot directly reflect the speed of the car. It usually requires a lot of human judgment to achieve, which makes control more difficult and the collaborative control accuracy is also low.

[0061] At present, although there are all-in-one machines that combine RF receiving systems and model components, they simply open up interfaces to achieve integration, and data communication between the model components is not realized, resulting in the inability to coordinate work between the model components and low collaborative control accuracy of the model components.

[0062] Therefore, how to improve the coordinated control accuracy of various model components while ensuring that the control delay does not increase has become a technical problem that needs to be urgently solved in the field of remote control technology.

[0063] To solve the above technical problems, please refer to Figure 2 , an embodiment of the present invention provides an RF receiving system, which may be configured to include:

[0064] A power input unit, electrically connected to each unit of the RF receiving system, and configured to provide power to each unit of the RF receiving system;

[0065] An interface unit, connected to the model components of the controlled model, can be configured to receive real-time model status signals input by some model components, wherein the model components include but are not limited to: motors, lamp groups, steering gears, built-in or external sensors;

[0066] The command processing unit is connected to the RF control system and the interface unit, and is used to receive the model control RF signal and model setting information sent by the RF control system; generate a control channel signal by fusing the model control RF signal, the real-time model status signal and the model setting information; and obtain a channel pulse control signal or a power on / off control signal by parsing the control channel signal, wherein the command processing unit includes: a serial port signal pin, a pulse control signal output pin and an on / off control signal output pin;

[0067] The interface unit is also connected to the serial port signal pin, the pulse control signal output pin and the on-off control signal output pin, and can also be configured to transmit the control channel signal, the channel pulse control signal or the power on-off control signal to each model component to achieve coordinated control of each model component.

[0068] In the example of the present disclosure, the power input unit may be a battery interface provided on the RF receiving system, which may support a wider voltage input. In this embodiment, the supported voltage range is 3.5 to 26V.

[0069] The command processing unit can be a command processing chip arranged on the RF receiving system, and the command processing chip includes: a wireless receiving module, a plurality of pulse signal output pins and a plurality of on-off control pins, and two serial port pins. The command processing unit can integrate the signal analysis and computing capabilities for the output interface through the above-mentioned signal analysis and fusion operation. In this embodiment, through the command processing unit, it is possible to realize the integration of model components such as control motors, lights, servos, built-in or external sensors. Specifically, according to the type of control required, a data fusion algorithm can be selected to generate a control channel signal, a channel pulse control signal or a power on-off control signal, and the motor, light, servo, built-in or external sensor can be collaboratively controlled.

[0070] Please refer to Figure 3 The RF receiving system provided in the embodiments of the present disclosure, by setting an interface unit in the RF receiving system, there is no need to separately set an electric adjustment unit outside the RF receiving system, and the controlled devices such as the light group and the servo module can realize coordinated control of model components such as motors, lights, servos, built-in or external sensors, and can also directly connect some model components such as the induction lines on the motors and external sensors to obtain real-time status data of the motors or external sensors, such as real-time data such as the motor's speed, temperature, and load.

[0072] The first interface module is serially connected to some model components of the controlled model and can be configured to receive real-time model status signals input by some model components and transmit control channel signals to some model components. The first interface module can be configured as a serial port interface module.

[0073] The second interface module is connected to the command processing unit and each model component, and can be configured to transmit the channel pulse control signal or the power on / off control signal to each model component. Among them, the first interface module can be configured as a control interface module, and the second interface module can be set according to the control requirements, and can be set as a channel pulse second interface module, through the on / off second interface module, the channel pulse second interface module can be configured as a pulse width modulation interface module, and can also be configured as a pulse position modulation interface module. By setting the second interface module, a variety of control outputs of the RF receiving system can be achieved, and the adaptation range of the RF receiving system can be increased. The embodiment of the present invention can transmit the channel pulse control signal or the power on / off control signal to the model component through the second interface module, so as to realize the pulse control or power on / off control of each model component. In the embodiment of the present invention, the control channel signal can also be transmitted to some model components through the first interface module to realize the serial port signal control of some model components.

[0074] In an embodiment of the present disclosure, the command processing unit may also be configured to include:

[0078] The pulse control module, whose input end is connected to the command processing main module and whose output end is connected to the signal pin of the second interface module through the pulse control signal output pin, can be configured to parse the control channel signal according to the model setting information to obtain the channel pulse control signal, and output it to the second interface module to realize the pulse control of each model component. The pulse control module can modulate a preset channel pulse width signal or channel pulse position signal to realize the control of the speed, direction, voltage, current, temperature, etc. of each model component.

[0079] The on-off control module, whose input end is connected to the command processing main module signal and whose output end is connected to the negative pin of the second interface module through the on-off control signal output pin, can be configured to parse the control channel signal according to the model setting information to obtain the power on-off control signal, and output it to the second interface module to realize the power on or off of each model component. The control channel signal can be used to control the power on and off of the corresponding second interface module through the on-off control module. Among them, the on-off control module can be set to connect the second interface module to the ground, so that one interface can be used as a pulse control signal and power supply interface to connect model components (such as a servo), or it can only be used as an on-off control interface to connect model components (such as connecting a lamp to realize the on and off control of the lamp).

[0080] The serial port module can also be configured to transmit the control channel signal back to the first interface module to implement signal control of some model components.

[0081] In an optional embodiment of the present disclosure, the command processing unit is further configured to receive a model control radio frequency signal and model setting information sent by the RF control system; parse the model control radio frequency signal to obtain a first control channel signal, and parse the model return information from the real-time model state signal; generate a new second control channel signal by fusing the first control channel signal and the model return information; parse the second control channel signal to obtain a channel pulse control signal or a power on / off control signal;

[0082] Among them, the model feedback information includes but is not limited to: real-time speed, real-time steering, real-time temperature, real-time voltage, real-time current; the model setting information includes but is not limited to: speed threshold, steering threshold, temperature threshold, voltage threshold, current threshold; the control channel signal is used for but not limited to: controlling motor speed or direction, steering servo direction, brake lights, reversing lights, turning lights, and warning lights.

[0084] It should be noted that by generating a second control channel signal that carries the second speed channel value and matches the speed, the motor speed can be maintained constant, that is, the motor speed can be maintained constant by automatically increasing or decreasing the speed control channel value. When the model is driving on a flat road, the motor speed can be kept constant by automatically increasing or decreasing the speed control channel value, thereby ensuring the constant speed of the model. When the real-time speed of the model drops to the braking threshold, the RF receiving system can automatically fuse and generate the bearing braking channel value, thereby generating a new second control channel signal that matches the speed to control the brake lights to light up; when the real-time speed is detected to be reversed, it can be determined that the model is reversing, and the reversing channel value can be automatically fused and generated, thereby generating a new second control channel signal that matches the speed to control the reversing lights to light up; when the model is detected to be turning sharply, the sharp turn channel value can be automatically fused and generated, thereby generating a new second control channel signal that matches the speed, so that the hybrid control motor sharp turn speed drops, and the model can slow down when turning sharply.
