In the conventional apparatus using the dc motor, the dc motor is generally driven by using a driving unit including a transistor or a MOS transistor, and the driving unit is disposed on a main control board. In this manner, when the number of motors increases, the more driving units are required, that is, the more electronic components are required, resulting in an increasingly large area of the main control board.

The embodiment of the utility model provides a motor control system and massage device can reduce the area of master control board.

In a first aspect, an embodiment of the present invention provides a motor control system, please refer to fig. 1, the motor control system includes: a main control board 10, at least m sub-control boards 21, and at least m motors 22.

In the motor control system, the nth motor 22 is provided on the nth sub-control board 21, the nth motor 22 is electrically connected to the nth sub-control board 21, and the motor 22 is drive-controlled by the sub-control board 21. The first sub-controller board 21 to the mth sub-controller board 21 are serially connected in communication in turn, and the first sub-controller board 21 is also serially connected in communication with the main controller board 10.

In the motor control system, the main control board 10, the first sub-control board 21 to the mth sub-control board 21 are sequentially communicated in this order. The main control board 10 is configured to send first operation information of each motor to the first sub-control board 211, where the first operation information may include at least one of operation start time, operation duration, operation frequency, and operation intensity of each motor. The first sub-control board 21 is used for receiving the first operation information, controlling the first motor 22 to operate according to the first operation information, and sending the operation information of the second to mth motors 22 to the second sub-control board 21. The ith sub-control board 21 is configured to receive second working information sent by the (i-1) th sub-control board 21, control the ith motor 22 to work according to the second working information, and send the working information of the (i + 1) th to the mth motors 22 to the (i + 1) th sub-control board 21, where the second working information is the working information of the (i) th to the mth motors 22. The mth sub-control board 21 is configured to receive the operation information of the mth motor 22 sent by the m-1 th sub-control board 21, and control the operation of the mth motor 22 according to the operation information of the mth motor 22. Wherein i is more than 1 and less than m, n is more than or equal to 1 and less than or equal to m, m is more than or equal to 2, and i, n and m are positive integers.

The m-th sub-control board refers to a terminal sub-control board in all the sub-control boards which are connected in serial communication in sequence. The working information includes the working start time, working duration, working frequency, working intensity, etc. of each motor.

And then, after receiving the first working information, the first sub-control board reads the working information of the first motor, controls the first motor to work according to the working information of the first motor, and sends data containing the working information of the third motor and the working information of the second motor to the second sub-control board. Similarly, after receiving the data sent by the first sub-control board, the second sub-control board reads the working information of the second motor and controls the second motor to work, and sends the data containing the working information of the third motor to the third sub-control board. And finally, after receiving the data containing the working information of the third motor, the third sub-control board controls the third motor to work.
