2.4G remote control car solution
Shenzhen Zuchuang Microelectronics Co., Ltd. exclusively develops the 2.4G remote control car solution: on the basis of the original ordinary four-function remote control car, it is upgraded to a wireless 2.4G remote control with low cost and simple and stable debugging. Using the global open 2.4G ISM frequency band, the remote control distance is long, the circuit is simple, the anti-interference ability is strong, the operation is stable, and the control is flexible. It can realize the remote control control of 25 remote control cars at the same time without interference.
This solution adopts wireless 2.4G remote control, including forward, backward, left turn, right turn, acceleration and braking functions. Low cost, simple and stable debugging.
1. Using low-cost 8-bit MCU, effective 12BIT high-precision sampling AD MCU, making the most cost-effective;
2. The low-cost 2.4G high-frequency IC has few peripherals and is easy to debug. It can be made into a module or directly placed on the PCB with the IC, which can meet the needs of different customers;
3. The remote control distance is long, and the distance of 2.4G open space can reach 60~100 meters;
4. The original 2.4G frequency hopping protocol can reduce code drop as much as possible and ensure an excellent operating experience when playing;
5. The original automatic code matching technology is convenient and worry-free, and can ensure that it can quickly enter the working state every time it is powered on, and there will be no conflicts or disconnection when multiple machines are playing at the same time.
remote control part
A: Turn on the working power of the transmitter, and the system will enter the normal working mode (if the receiver is turned on, it will automatically pair the code soon).
B: When the front and rear control handles of the transmitter return to the neutral position, the system will control the receiver to be in a stationary state. The front and rear handles can be controlled
To control the receiver to move forward and backward. Twist the direction knob to control the receiver's left and right turning direction.
C: Low voltage reminder function: According to customer requirements, when the power supply voltage is lower than the normal working voltage (can be set), the system enters the low voltage reminder function.
D: Power-saving function: When the transmitter is in the middle state (the motor does not operate), and the button function does not work for 10 minutes, the system enters the power-saving working mode.
E: LED indicator light: In normal working mode, the LED indicator light is always on. Corresponding functions can be added or changed according to customer requirements.
receiving part
A: Within the range of the remote control, the receiver can move forward, backward, left, and right, so as to realize movement control in all directions.
B: Low voltage reminder function: According to customer requirements, when the power supply voltage is lower than the normal working voltage (can be set), the system enters the low voltage reminder function.
C: Power-saving function: When the transmitter is in the middle state (the motor does not operate), and the button function does not work for 10 minutes, the system enters the power-saving working mode.
D: Locked rotor detection function: The locked rotor current can be set according to customer requirements. (Generally, remote control cars do not do this function, if the current is large, such as aircraft models, it can be set)
