Remote control panels regard the STC12C5A60S2 microcontroller as core and use the MMA7361 to capture the remote board tilt angle. Remote control panels use the NRF905 to wireless transmission. The car system is using the NRF905 to receiving control instruction , process data by STC89C52 microcontroller and drive the motor with L298N. The remote control system use the MMA7361 sensor to acquisition tilt angle, it is relative to the current tilt angle of the mercury switch acquisition, has the characteristics of high precision of angle measurement, safety, reliable performance. The wireless transmission is used in NRF905 module, and it’s safe to transmission by the software encryption, and strong anti-interference ability. The motor drive is by the L298N. One module can drive two motors. Relative to the current mainstream BTS driver is a number of single drive. The experimental results show that, this design has the advantages of low cost, high reliability, high precision, convenient installation and debugging of features. It’s very suitable for car manufacturers to improve market compe
