The health industry is a sunrise industry in the 21st century. In recent years, with the rapid development of the economy and the continuous improvement of living standards, health care has gradually become a social life concept. Thanks to advances in new materials and electronic technology, the massage ball device has been miniaturized and precisely controlled, which greatly enhances the comfort of the massage device, and the massage device is increasingly favored by consumers. As a sub-product of massage equipment, the massage chair is attracting the attention of many investors. With the continuous influx of many enterprises, the massage chair industry has developed rapidly and has shown rapid growth.
So, what is the working principle of the intelligent massage chair? The control system first completes the initialization of the hardware software, then scans the keyboard input, and performs various functions according to the module interface set by the key code. The software sets the continuous running time of each motor, and the DC motor is driven by PWM, and the speed of the motor is realized by changing the pulse width of the PWM.

As can be seen from Figure 1, the main components and functions of the massage chair can be divided into:
Main board: a carrier used to control the operation of the massage chair program, the power supply, and the pneumatic valve motor;
Movement: The movement of the massage chair is equipped with a robot and a motor that controls the motor of the manipulator;
Guide rail: The guide rail is the main body of the massage chair, with the movement robot and most of the main internal components;
Manipulator: The manipulator of the massage chair can realize a variety of artificial massage techniques through the design of the program;
Motor: Commonly known as a motor, its main function is to generate drive torque, as a power source for electrical appliances or various machines.
For the massage chair control, the Renesas Electronics RL78/G13 MCU from Shiqiang can realize the main control function of the massage chair. The RL78 is a new generation microcontroller series of Renesas Electronics, which integrates the advanced features of the 78K and R8C series. Low power consumption and high performance. Designed for ultra-low power applications, enabling users to build small, energy-efficient systems at a lower cost.

Among them, RL78/G13 has excellent CPU performance, more than 1.27DMIPS/MHz, and integrates a variety of peripheral devices, which can reduce the board area and reduce the overall cost; it is fully pin-pin compatible with the same series of products, supporting peripheral I / O Reorientation (PIOR): Some pins can be redefined; easy layout and ultra-low power consumption will help you create a small, energy-efficient smart massage chair.
