Composition of remote control equipment
The remote control equipment is generally composed of transmitter, receiver and servo steering gear (or electronic governor).
1. Transmitter - used to convert manipulation commands into radio signals with control information and radiate into the air. There are two types of transmitter stick type and gun type for vehicle models. The stick transmitter has two joysticks, the left one is used to control the speed and braking (or backward) of the model car, and the right one is used to control the direction of the model car. Shotgun transmitters use a wheel (steering wheel) and a joystick similar to a pistol trigger to control direction and speed, respectively. In addition to these basic functions, some higher-level transmitters also use advanced computer technology and add many additional functions, such as storing the adjustment data of multiple model cars, one machine is multi-purpose; it has timing and lap counting functions, which is convenient for practice. and games; there is a large LCD screen that can display the working status and various functions.
2. Receiver - is used to receive the radio signal sent by the transmitter. Since the receiver is installed on the model car, it is generally made as small as possible. For example, the FUTABA R-113F receiver made in Japan is only the size of a match and weighs only 18g. It has high sensitivity and can receive radio signals transmitted from nearly a kilometer away. The receiver is generally used in conjunction with the transmitter, usually using a six-volt DC power supply (4 AA batteries).
3. Servo steering gear and electronic transmission - the function of the servo steering gear is to convert the electrical signals received by the receiver into corresponding mechanical actions, thereby completing the control of direction and speed. Servo steering gear can be divided into ordinary steering gear, powerful steering gear and micro steering gear according to different purposes. Ordinary steering gears can meet general usage requirements; powerful steering gears are usually used on larger models or control mechanisms with greater force (such as the steering mechanism of off-road vehicles); miniature steering gears are often used for both size and force. On a smaller model car. The electronic transmission is used in electric model cars. It is a kind of servo device specially used for speed regulation. Compared with ordinary mechanical speed regulators, it has the advantages of small size, long life, high efficiency and high output power. Some advanced electronic transmissions also use digital technology, use high-frequency operation, and have multiple program braking, temperature-controlled automatic protection, and automatic power-off functions.
